On May 14th, after many preheating, Lenovo finally showed their Windows 10 PC folding screen prototype equipment in new york.

This unnamed 13.3-inch device will be released in 2020, equipped with a 4:3 2K OLED folding screen, and the screen supplier is LG, which is an Always Connected PC driven by Intel processor, which can provide full-day battery life.

According to Lenovo, the device will be sold in ThinkPad X1 brand series, so it is more durable than a simple consumer laptop. It will be equipped with Wacom stylus and Bluetooth keyboard to improve the actual work efficiency. In addition, it also supports USB-C charging.

As the use scene of Lenovo Windows 10 PC folding screen, you can fully unfold it like a large tablet computer or partially fold it into a book shape. The built-in stand allows you to support the display screen on the desktop for use with the included wireless keyboard and touchpad.

In addition to completing the final design, Lenovo is still waiting for Microsoft to provide Windows system software support for the folding screen device PC-it can be seen that the soft keyboard does not cover the whole lower part of the screen.

The hit drama "One Mind to Pass the Mountain" is the 85-flower Liu Shishi’s comeback by relying on the costume drama. Since its launch, the popularity of this drama has been rising continuously, and many discussions have been involved. Surprisingly, however, there is no actor in this drama, the official match of Liu Yuning is too worn down, and the male master and apprentice back to Germany and Chang Huasen is a short man to choose a general. On the contrary, Wallace Huo, who had worked with Liu Shishi for three times before, got angry.

Not only did netizens directly replace the face of the leading actor with him, but a platform also deliberately exempted Wallace Huo and Liu Shishi from "A Strange Man’s Plum", and Wallace Huo himself soared in popularity in a small book, becoming a hot figure in making up homework (chasing old dramas) after 05 and 10, and madly rolled up a group of fans.

It’s really hard to imagine that the Internet has really changed a group of people. It seems that everyone has forgotten that Wallace Huo married Ruby Lin because of his poor acting skills, and he was almost scolded to quit the circle. Now it has become a myth of the Internet. I really want to thank my peers for all this.

Excellent face value, Internet substitution can also be played.

The four beauties of the world are not boastful. It is not without reason that I wear a Mao Mao to give you branches in the snow in bilibili every day in winter. The heart is strictly selected from the retention money, and Wallace Huo’s face value is beyond doubt.

When I was young, I was filming without makeup, and I was fresh and natural. When "chinese paladin 3" was broadcast, one of the hot reviews of Douban in that year was: "I watched this drama for Hugh and fell in love with Wallace Huo."

Vivian Wu, who has seen so much of the world, and the woman who has filmed in John Lone, the so-called Asian grass, have always been full of praise for Wallace Huo’s eyes. They have cooperated with him several times and praised his big eyes, so you feel that you can’t help it, and you will forgive him for what he has done.

Therefore, it is not surprising that with such a face here, even if the Internet has changed, it is no longer the wave of people who used to surf the Internet, but people will still fall for the same face again and again. Although it is said that the aesthetic is degraded now, the reason for the degradation is not that everyone’s aesthetic is not good, but more because there is nothing good for everyone to see. Since there is something good to see, why do people choose bad things?

The character is not bad, and digging the old man will not collapse the house.

Now the biggest problem of these traffic stars is that they are easy to collapse. One by one, all kinds of scandals followed, such as divorce, marriage, hidden marriage and cheating marriage. In this way, a person who has been debuting for twenty or thirty years and basically has no black material is not afraid of the collapse of the house.

For some time, the biggest rumor spread to Wallace Huo was that he was whoring while filming, but Wallace Huo could not bear to take it to court directly, winning one fight at a time.

In addition, Wallace Huo has no problem with their hometown artists’ problems of playing big cards and political stance.

Wallace Huo’s filming habit is still very famous. He doesn’t need an assistant to carry an umbrella and carry water to wear shoes. He takes a little assistant alone and has no shelf at all, so he has the saying of retired cadres.

As well as his family background and his name, everyone can see that "Wallace Huo" doesn’t have any political stance that makes everyone criticize him.

The collapse of the house is really annoying. idolize, a fan, chased it well and ended up sleeping or paying taxes. On the one hand, the collapse of the house makes everyone feel that their true feelings have been fed to the dog. On the other hand, they really feel ashamed and like a person. How can the other party collapse? Hating yourself is really bad. Wallace Huo, for example, has been in the entertainment circle for most of his life, and there are no black spots and stains in front of him, so it is reassuring to catch up.

It’s not surprising that the new powder can be used in into the pit.

When I made my debut, I shot an idol drama in Taiwan, China by mistake, but I was not satisfied with the ordinary idol drama. I went north to the mainland to shoot ancient costumes, and the ancient costumes also became popular. The quantity and quality of his works can stand the test.

Nowadays, these young artists can only watch one or two works, and most of their achievements are based on the data boasted by fans. Compared with so many works that can be seen in Wallace Huo, it is far from enough. Even the characters who were spit out at the beginning are all works that look very good now.

Ruyi’s Royal Love in the Palace, which everyone talks about the most, feels that he has been crushed by Zhou Xun in all directions, but we have to say that his role as Slag Dragon is indeed worthy of so many women’s love for him.

There is also "A Strange Man and a Plum", which is just like this time "One Mind to Pass the Mountain". This drama is really good-looking, and Douban scored 8.5, which is called the last swan song of martial arts drama. The loyalty of the squad; Distinctive setting and shaping of characters; Unique music assistance, anything is hard to see at the moment, let alone a combination. Many other ancient works of Wallace Huo can also bring them a lot of joy when they dig graves in Xinfen.

In the mixed circle, there is a saying that there are only two kinds of hybrids in the world, one is Toyota hybrid and the other is others. This is enough to prove the recognition of Toyota THS hybrid system in the industry. Today, we will talk about the planetary gear mechanism, the core component of this world-renowned hybrid system.

Toyota THS hybrid system is mainly composed of Atkinson cycle engine, permanent magnet motor, planetary gear mechanism, generator, high-performance nickel-hydrogen battery, power control unit and power control unit.

The core of the whole system is this planetary gear mechanism, that is, the E-CVT transmission in the media population. However, although it is called a transmission, it does not have such complex mechanisms as clutches, torque converters or gear shafts in the traditional transmission system, and it is a power distribution mechanism specially prepared for hybrid vehicles (the official name of Toyota).

So what are the advantages and disadvantages of Toyota’s system, and what are the differences between them compared with other hybrid systems on the market? This article will be reflected one by one.

1. Why does Toyota develop the E-CVT transmission?

E-CVT transmission is the key to the whole hybrid system, and the original intention of all hybrid systems can actually be attributed to energy saving and emission reduction, as was Toyota’s launch of THS that year.

In the early 1990s, the words such as "sustainable development", "global warming" and "greenhouse effect" began to be known around the world. Under this background, Toyota began to study "automobile development model in the 21st century" and launched a project called "G21" (G stands for Globe 21 and stands for 21st century). Toyota Hybrid Power System (THS) also began to sprout at this stage.

In 1995, Toyota released the Prius hybrid concept car at the Tokyo Motor Show. Two years later, in 1997, Toyota’s first generation Prius hybrid car went on sale in Japan, which was Toyota’s first mass production model based on THS hybrid system and the first model born under the Toyota MC platform.

Here, Toyota’s hybrid world door is officially opened.

Second, at present, the THS hybrid system has developed to which generation, and which models are it mounted on?

As mentioned above, the core of THS system is actually the E-CVT transmission, that is, the planetary gear set, and the iterative upgrade of Toyota THS system is almost around the planetary gear set.

The first generation THS hybrid system was born in 1997, and it was first mounted on Prius. Its planetary gear set consists of three parts: sun gear, planet carrier and outer ring gear, which correspond to three power sources in turn: the engine is connected with the planet carrier; Sun gear is connected with the MG1 motor; The gear ring is connected with the MG2 motor.

Through precise and complex control, this planetary gear set can shunt the engine and use the motor to adjust the speed, so that the engine has been in an efficient working range, so as to achieve the purpose of saving fuel.

In 2003, Toyota introduced the second generation THS hybrid system, but the upgrade of the second generation THS hybrid system was mainly in the aspect of electronic control, and the structure of E-CVT transmission did not change much.

In 2009, Toyota introduced the third generation THS (officially called the second generation, but the industry prefers to call it the third generation). Compared with the second generation THS, it added another planetary row on the basis of the original planetary row. The second planetary row is connected with the gear ring of the first planetary row, the MG2 motor is connected with the sun gear, and the planet carrier is fixed, as shown below:

In this way, the second planetary row becomes the deceleration mechanism of MG2 driving motor, and the output torque is increased by reducing the rotation speed, so the third generation THS of Toyota has better power performance than the previous two generations. Not only that, because of the addition of a first-stage reducer, the cumbersome chain drive was replaced by a lighter and smaller gear drive, which greatly improved the transmission efficiency.

However, due to the limitation of planetary gear structure, the speed of MG2 driving motor is limited by the limit speed of MG1, so the speed of this system in pure electric mode cannot be very high (about 70km/h).

In order to better adapt to the development of the industry, Toyota introduced the fourth generation THS in 2015. In terms of structure, the most significant change in this upgrade is to change the planetary gear added by THS-III into a parallel shaft gear, and at the same time put the MG2 driving motor in the side position.

The obvious advantage is that the axial dimension of this system is reduced by 47mm, which is undoubtedly a technological innovation in the horizontal platform with an inch of land and gold. It can not only adapt to engines with larger displacement, but also make the power of MG2 driving motor higher.

In addition, Toyota also introduced a plug-in hybrid system based on the fourth generation THS in 2016. Its main change is to add a single clutch between the engine and the MG1 motor.

The function of the one-way clutch is that when the MG1 motor participates in the driving function (more often used for starting and generating electricity), it will not drive the engine to rotate together, and at the same time, it forms a dual-motor drive with the MG2 driving motor.

The structural diagram of this one-way clutch is as follows. The structure determines that it can only rotate in one direction.

From the year, Toyota E-CVT has gone through several iterations, as shown in the following figure:

(first generation THS)

(second generation THS)

(third generation THS)

(fourth generation THS)

In addition, there are hybrid systems applied to vertical platforms (the version code has not been found yet), such as Lexus LS and Lexus GS. Compared with the ordinary version of THS hybrid system, it connects a 4AT in series to simulate 10 gears. The result of this combination, on the one hand, is conducive to improving the speed, for example, the pure electric maximum speed of LS500h can reach 140km/h, on the other hand, it is more accelerated.

The four-wheel drive system applied to Erffa and Lexus LM is composed of an E-Four electric four-wheel drive with a separate motor in the rear axle, which is not much different from Toyota THS in structure.

At present, Toyota THS models that have been introduced into China include: Camry, Highlander, Saina, Willanda, Lei Ling, Visa, C-HR, Corolla, RAV4 Rongfang, Asia Dragon, Crown Lu Fang, Lingfang HARRIER, Yize IZOA, Erffa and Wilfa; Lexus brands include lexus ES, Lexus RX, Lexus NX, Lexus LS, Lexus UX, Lexus LM, Lexus CT, Lexus LC and Lexus GS(2016, 2014 and 2012 models).

III. Detailed explanation of E-CVT (officially called THS-II version)

3.1, structural composition

The core of E-CVT is this planetary gear set, which consists of sun gear, planetary carrier (including planetary gears) and external gear ring, which are connected with MG1 motor, engine output shaft and main reducer in turn, as shown in the following figure:

We can find that as long as the state of one mechanism is determined, the rotation of the other two mechanisms can also be determined. For example, if the external gear ring is stationary and the sun gear rotates, it will inevitably drive the planet carrier to rotate, which is the starting process of the vehicle.

Moreover, it is worth noting that the diameters and teeth numbers of the external gear, the sun gear and the planetary gear are fixed, which means that the torque of the engine will always be distributed to the sun gear and the external gear in proportion, and the specific value is about 72% to the external gear and 28% to the sun gear. Once the engine is running, this basic fact will not change.

In addition, due to the structural limitation of the planetary gear set, the gear ratio between the outer ring gear and the sun gear is 2.6, that is, when the outer ring gear rotates once, sun gear has to rotate 2.6 times. As a result, the speed of the M2 motor is limited by the limit speed of the M1 motor of 6,500 revolutions, which is only 2,500 revolutions, corresponding to the speed of the vehicle of 43 miles per hour, that is, about 70 kilometers per hour.

3.2, working mode

Toyota’s THS-II system can essentially realize a variety of working modes, one is pure electricity, the other is hybrid (both B and C in the picture below can be regarded as hybrid), and the other is kinetic energy recovery mode, which we will explain in turn from easy to difficult.

First, the pure electric mode. In the pure electric low load state, the battery drives the MG2 motor, and the power is transmitted to the front axle differential by MG2, which finally drives the wheels. However, because the outer gear ring of the planetary gear is hard connected with the M2 motor, it will also follow the rotation. At this time, the engine connected with the planetary carrier has internal resistance, and the power will be transmitted to sun gear, that is, M1 generator with smaller internal resistance through the planetary gear, so that it rotates in the opposite direction, and the generator is in a state of idling without generating electricity.

In the pure electric load state, at this time, the one-way clutch of the engine output shaft intervenes, the planet carrier remains motionless, the MG1 generator starts to act as a motor, the power is transmitted to the outer ring gear through the sun gear, and the wheel is transmitted to the front axle differential through the parallel shaft, and finally the vehicle is driven forward together with MG2.

The kinetic energy recovery mode is better understood. When the vehicle is decelerating, the wheels will drive MG2 and MG1 in turn, making them act as a generator.

Hybrid mode:

Compared with the first two working modes, the hybrid mode can reflect the essence of the whole system of E-CVT. When the motor power can no longer meet the demand, or the battery power is not enough, the engine needs to start and intervene at this time.

However, the engine of this system has no traditional starting mechanism, so at this time, the MG1 motor needs to turn from reverse rotation to forward rotation, so as to drive the planet carrier to rotate, and this speed will reach the efficient range of engine operation, and then the engine will start with fuel injection.

As we mentioned earlier, once the engine rotates, the torque of the engine will be transferred to the outer ring gear and sun gear, and at this time, the outer ring gear will transfer the power to the front axle differential coupled with it to drive the wheels together with the MG2 driving motor; Sun gear will drive the MG1 motor to generate electricity, which will be provided to the MG2 drive motor.

When we step on the accelerator deeply, or when we are at full load, there are three power flows. Except that part of the torque of the above engine drives the wheels and part of the torque drives the MG1 generator to supply power to MG2, the battery of the vehicle itself will also supply power to the MG2 motor, so that the vehicle can output the maximum power.

Another mode is in-situ power generation, in which all the engine power drives the MG1 generator to charge the battery. Perhaps some readers have found it here. Didn’t you say that as long as the engines move together, the torque must be distributed to the outer ring gear and sun gear in proportion?

(In-situ charging)

There is actually no conflict here, because in the in-situ power generation mode, the battery will supply power to the MG2 motor, provide a reverse torque, and lock the external gear ring.

3.3, control strategy

The structure of planetary gear set is not complicated, but the control unit of the whole system is difficult. After the engine starts and the system enters the hybrid, how to distribute the power?

First of all, we know that the MG1 motor can be regulated, and according to the relationship between planetary gears, the torque of engine torque distributed to the outer ring gear can be calculated. When the driver steps on the accelerator pedal, the system will judge the power required by the engine according to the accelerator opening and the SOC value of the battery. When the vehicle speed is low, most of the power of the engine will be distributed to NG1 for power generation, part of the power will be used to drive the wheels, and the rest will be supplemented by M2 motor.

When the vehicle speed is high, the engine will use most of the power to drive the wheels, and only a small part will be used to generate electricity, and the MG2 motor will assist in driving.

If the vehicle happens to be in the highest thermal efficiency range of the engine, the MG1 motor will get stuck, and the MG2 motor will idle, at this time, the power is completely provided by the engine.

From the above, we can also draw another conclusion: the engine is responsible for the main power output, which is used to maintain SOC balance and respond to the total power request; The generator is used for speed regulation, and its purpose is always to control the engine speed at the target working point; The motor is mainly responsible for supplementing the torque to ensure that the driver’s torque request is guaranteed.

IV. Advantages and Disadvantages of E-CVT

The E-CVT transmission has two advantages. First, the smoothness of driving. The planetary gear set replaces the transmission, and there will be no sense of frustration in shifting gears. At the same time, the system is simple in structure and more reliable in theory.

Secondly, this system can keep the engine in an efficient running range through the power split of planetary gear sets and the speed regulation of the motor, and make the fuel economy higher. We should know that the measured fuel consumption of the third-generation Prius was 4.3L/100km when it went on the market in 2009. It reached this fuel consumption level 10 years ago, which can be said to be ahead of the whole era.

Although the advantages are obvious, this set of E-CVT also has some inherent defects, mainly because of the restrictions brought by the gear structure. For example, the gear ratio of the planetary gear set limits the speed range of the engine, and at the same time, it needs to drive the generator to generate electricity, which cannot release all the power. Moreover, the more transmission paths of the gear set, the greater the energy loss; In the high-efficiency operation range of the engine, the power cannot be completely transmitted to the wheels, and it needs to be converted twice by charging or electric drive.

5. What is the current reputation of E-CVT?

Generally speaking, due to the special type of gearbox, E-CVT will not produce friction when working, and will not wear without friction, with better durability and low failure rate.

From the market reputation, we can also see the reliability of this system, and there are almost no complaints about the failure of E-CVT transmission, which also reflects its leading quality.

VI. Comparison of E-CVT Technology

Due to the limitation of patents, there are not many E-CVT with planetary gear sets as the core. Besides Toyota’s, the most famous one is the universal Volt dual-mode hybrid system (in fact, GM’s patent in this respect is earlier than Toyota’s), which also takes planetary gear sets as the core.

Structurally, the MG2 of the universal Volt is connected with the sun gear, the output shaft is connected with the planetary carrier, and the power is output to the wheels, while the gear ring is connected with the shell or the motor MG1 according to the actual operation. Through the combination and separation of clutches C1 and C2 and brake B1, GM Volt can realize various operation modes, as shown in the following table.

Compared with Toyota’s E-CVT, although the Volt structure of GM is similar, the direction of power split is completely different, which is also the product of Toyota’s racking their brains under the blockade of GM’s patents.

In addition, it is worth mentioning that although the Volt is more similar to Toyota’s YHS in structure, consumers compare more with Honda’s i-MMD hybrid and Toyota’s THS hybrid, so we also make a comparative analysis of them.

First of all, in terms of structure, Honda’s i-MMD system consists of engine, generator, driving motor, power separation device (E-CVT), PCU and lithium battery.

One of the key differences lies in the E-CVT. Compared with Toyota’s complex planetary gears, Honda’s i-MMD completes the power split through very few gear sets and clutches, and we have to know that one more transmission path of power leads to one more loss.

Compared with Toyota’s THS, Honda’s i-MMD is characterized by high structural flexibility, which can realize pure electricity, series, parallel, high-speed direct drive (Toyota THS can’t realize direct drive) and other modes, and its efficiency is very high.

In addition, the hybrid power of Honda i-MMD is higher than that of Toyota THS. Take the third generation Honda i-MMD as an example, its total motor power reaches 135KW, while that of Toyota THS-IV is only 53KW.

As for why Honda i-MMD uses such a high-power motor, the main reason is that Honda i-MMD hybrid system can’t switch the speed ratio at will like Toyota THS, so this system is in series mode under most working conditions, and the motor drives the vehicle. In order to ensure the power of the vehicle, only a more powerful motor can be selected.

It also has some disadvantages: the battery uses lithium battery, the motor power is higher, and the corresponding cost will be higher. At the same time, because it is limited by the speed ratio of the internal reduction gear set, the working space of the Atkinson engine in the i-MMD system that directly participates in driving the wheels is very narrow. In addition, Toyota’s THS has been verified on a large scale in the market, and its reliability has been proved.

Seven, Toyota open E-CVT patent.

At the beginning of the article, it is said that there are only two kinds of hybrids in the world, one is Toyota and the other is others. The reason for this statement is that on the one hand, Toyota THS hybrid performance is excellent and reliable, on the other hand, it has applied for comprehensive patent protection, and it is even more difficult for latecomers to enter the market.

However, due to the timeliness of the patent protection period, in 2017, Toyota announced the opening of the first batch of hybrid patents, and it can provide technology to the outside world, and hopes to cooperate with other car companies in this regard, but there are few respondents.

By 2018, Toyota expressed the patent opening more clearly, claiming that it would provide the right to use for free, including about 23,740 patents of electrification technology such as motor, electronic control and system control.

In 2019, the opening of Toyota’s patent finally ushered in the harvest. First, Toyota "sold" THS technology to Toyota’s core component supplier Keliyuan in China at a price of "US$ 1" (Keliyuan’s major shareholder is Geely, so it can be understood as selling technology to Geely in disguise). Later, it reached a THS hybrid technology transfer agreement with GAC and FAW.

At present, the first Guangzhou Automobile Chuanqi GS8 twin-engine series equipped with Toyota hybrid in its own brand has been listed. The power is a 2.0T engine independently developed by Guangzhou Automobile+Toyota THS hybrid system, and the official fuel consumption per 100 kilometers is 5.3L/ 100 kilometers. In addition, Geely’s Zhiqing Hi·X oil-electric hybrid system is also inextricably linked with it.

Summary:

Generally speaking, as the core of Toyota THS hybrid system, E-CVT transmission perfectly realizes the function of power shunting through planetary gear sets, and makes the engine always in an efficient working range by using motor speed regulation. This is indeed a revolutionary innovation, which also makes Toyota’s hybrid technology almost dominate the world, and its cumulative sales volume is close to 20 million. At present, THS hybrid has developed to the fourth generation, and its structure has approached perfection. Moreover, in the context of pure electric vehicles becoming the general trend, whether Toyota will continue to upgrade THS or improve E-CVT may require a question mark.

The blind road in the city is very busy. The blind man tells us that there are too many "traps" on the blind road, which is unsafe.

Dahe News (Reporter Li Shuai) Core Tip | "My eyes are intact, but why can’t I see them." In an interview the other day, a Zhengzhou citizen asked our reporter a question: Why did they walk to and from work for three years, but they didn’t see a blind friend? Where did they all go?

According to the data released by the World Health Organization in 2010, there are 8.248 million blind people and 67.274 million people with low vision in China. There are many blind people, but why do we seldom see them in our daily life?

doubt

Why can’t I see a blind man after walking the blind road for three years?

At 7 o’clock on the morning of December 19, on Dongming Road in Zhengzhou City, 25-year-old Xiao Zhou just walked to the sidewalk on the side of the road, so he couldn’t help but take out his mobile phone from his pocket and slowly turned to the blind road. Along the way, except crossing the intersection, he hardly looked up; Even when waiting for the traffic lights, he looked down at his mobile phone from time to time. On the way, he almost ran into an electric car parked on the blind road twice, which made the reporters who followed him feel a cold sweat. Afterwards, when he found the reporter following, he also argued that he was experiencing the feeling of blind people traveling.

Xiao Zhou is a chef. Every day when he goes to work, he walks from the rented house to the hotel where he works, with a distance of more than 2,000 meters. On this section of the road, most of the time he will watch his mobile phone while walking in the blind road, and observe the road conditions on the blind road with the corner of his eyes. In his words, the blind road can guide his walking route, and his feet have been "exercised" very sharply. The straight line under his feet is straight, and when he meets a raised dot, he turns.

In addition, he also observes whether there are blind people on the blind road from time to time, but he has never seen a blind person on his way to and from work for three years.

"I am also puzzled. On the sidewalk, I may not notice the blind people around me, but why have I been walking on the blind road and never seen the blind people?" Xiao Zhou said that he is now used to walking on the blind road and observing whether there are blind people on the blind road. "I also want to help the blind friends I met, but why can’t I see them with my intact eyes. Did I go out at the wrong time? Or blind friends don’t go out? "

inner voice

It’s not that they don’t want to go out, but they are afraid to go out.

At 11 o’clock on the morning of December 20, the reporter met several blind friends in the blind massage service center of Sunshine House, Zhengzhou University Road. At this time, some of them are doing massage for the citizens, while others are cooking in the kitchen. Chen Qiang, 52, is one of the blind masseurs in this massage shop. When he was two years old, his cornea was burned by a high fever, and the medical conditions at that time limited him, so that he was blind since he was two years old. Now, the blind stick in his hand is his eyes when he goes out.

Why do you seldom see blind people in your daily life? When the reporter asked Chen Qiang about this question, Chen Qiang said with a sigh that it was not that they didn’t want to go out, but that they were afraid to go out. Although there are blind roads on the road for blind people to travel, there are too many "traps" on the blind road, which is unsafe. Before, when he was in Kaifeng, his hometown, he almost fell into a manhole without a manhole cover on the blind road. "At that time, one of my feet was already empty and I was about to fall in. Fortunately, a good-hearted person grabbed me in time."

Hearing this, another blind masseur next to me, Jin Guoquan, couldn’t help but say, "Last year, I broke my bone on the blind road in huanghe road, Zhengzhou, and I lost two thousand yuan after a year of litigation. Now I basically don’t dare to go out."

Not only Jin Guoquan was injured in the blind road, but even Zhao Wanfu, a blind masseur who was cooking, suffered losses in the blind road. According to Zhao Wanfu, half a month ago, when he went out to buy steamed buns, he was hung around his neck by a cable pole on the blind road. Although it was not very serious, his neck was burning for several days. "We also want to go out and go to the small park to bask in the sun, but there are too many unsafe factors on the road, so we can stay indoors."

In addition, Chen Qiang also told reporters that once, when he went out to buy things, he knocked and walked with a blind cane, and he accidentally knocked on a car on the blind road. The owner began to swear after getting off the bus. If other citizens had not stood up for him, he really didn’t know what to do at that time. Although it has been a long time since this incident, and he himself said that he can’t remember how ugly the words were at that time, it made him sad for a long time, and he was very grateful to the citizen who helped him speak.

In this regard, Tian Chao, vice chairman of China Blind Association and chairman of Henan Blind Association, said that according to their latest blind census, there are currently 76,400 blind people in Zhengzhou. Inconvenient travel and transportation are the reasons why many blind friends are reluctant to go out.

site

Line poles, isolation piles … There are many "traps" in street blind roads.

On the streets of Zhengzhou, there are blind roads on the sidewalks of almost every road, but these blind roads are either blocked by motor vehicles and non-motor vehicles, or occupied by telephone poles and isolation piles, or seriously worn, or even "broken" roads. During the interview, many blind friends interviewed said that there are too many "traps" on the blind road, so it is better not to leave.

During the visit, the reporter also saw many chaos on the blind road on the streets of Zhengzhou. For example, in the sections of Kangfuqian Street and Zhengqi Street in Zhengzhou City, telephone poles are directly erected on the blind road; On the South Yellow River Road, there are isolation piles directly on the blind road; On many roads such as Dongming Road and Hongzhuan Road, blind roads are cut off and blocked by motor vehicles and non-motor vehicles; Even the street merchants in some sections regard the blind road as an isolation line, and put dirty trash cans on the side of the blind road …

Imagine what would happen if we lost the light and walked on such a blind road? If you stand on a busy street, or stand at a bus stop and wait for a bus, close your eyes and experience the feeling of blindness, you will find that it seems that the whole world has become extremely unsafe, surrounded by noisy voices and unknown uneasiness. Even before you close your eyes, you already know that the road ahead is very flat, or you know how to get on the bus, but you will still be timid and afraid to move forward.

suggestion

I hope the blind road can really play its role and add more voice reminders.

During the interview, blind friends all expressed the hope that the blind road can really play a role, and that there will be fewer "traps" on the blind road and the design will be more reasonable. Especially at some small intersections where blind roads are broken, some voice reminders can be added so that blind people can pass safely. Among them, Master Zhang, a blind friend interviewed, asked whether it is possible to set up blind roads on the zebra crossing at the intersection so that the blind roads on both sides of the intersection can be connected together, so that the blind can continue to walk on the blind road after passing the intersection.

In addition, Chen Qiang, a blind friend interviewed, also asked whether it is possible to set up a voice reminder at the intersection of traffic lights, so that the blind can cross the road safely, instead of running the red light with the people next to them when they hear them walking forward.

In addition, Tian Chao, vice chairman of China Blind Association and chairman of Henan Blind Association, also said that blind people mainly rely on public transportation. If we can set up a voice reminder of blind people crossing the road at the intersection of urban traffic lights and install a bus guide system as soon as possible, it will not only ensure the safety of blind people’s travel, but also make it more convenient for blind people to travel.

According to the regulations on the practical assessment standard for the disabled in China (for Trial Implementation), the disability of visually impaired people is divided into four grades, namely, first-degree blindness (first-degree visual disability), second-degree blindness (second-degree visual disability), first-degree low vision (third-degree visual disability) and second-degree low vision (fourth-degree visual disability). For the convenience of description, blindness and low vision are expressed as "blind" in the report.

　　　 When the intelligent hardware configuration is soaring, the size of mobile phone screen is also rising rapidly. At present, although the iOS camp is still at the level of 3. 0, in contrast, mobile devices on Android and Windows Phone platforms have stepped into the big screen field one after another. Especially on the Android platform, when Samsung GALAXY Note appeared with a 5.3-inch large screen, people could not even tell whether it was a mobile phone or a tablet. However, in any case, the emergence of this kind of cross-border mobile phone with vague positioning has indeed made users experience the fun of swimming in the mobile Internet in the high-definition era, and has gradually become a bridge connecting smartphones and tablets.

Evaluation of 5-inch big screen music Phone S880

　　　 As a well-known domestic mobile phone manufacturer, Lenovo certainly saw people’s demand for large-screen mobile phones and the development direction of the smart phone market. Just in mid-June, Lenovo officially released its 5-inch screen smartphone, Le Phone S880. In addition to the large screen, it also has an ultra-thin fashion appearance of 9.9mm, supports dual-mode dual standby, is equipped with a 1GHz Cortex A9 core processor, is equipped with an Android4.0 operating system, and has a 5 megapixel camera and a battery with a capacity of 2250mAh. In addition, in order to give full play to the function of 5-inch screen in audio-visual entertainment, Music Phone S880 is also equipped with front dual speakers and analog gyroscope.

Front: big screen "leading the way"

　　　 The overall impression of Lenovo Music Phone is that it is a big word. This is mainly related to its 5.0-inch large screen. But if you look carefully, you will find that Music Phone has a soft breath in the atmosphere. When you hold it in your hand, it is not an alternative feeling, but a natural beauty. Of course, this may just be the charm of the "pearl white" color scheme, and Lenovo also provides users with the color scheme of starry night black to choose from.

　　　 The front of the fuselage is equipped with a WVGA cool large screen with a resolution of 800×480 pixels. Under normal observation, the color reproduction of the screen is still ideal and the graininess is not obvious. We try to adjust the screen to the brightest and darkest respectively, and we can see that the effect of the change is very obvious, which also means that Music Phone has good adaptability in different environments. However, this screen is also slightly regrettable, and the viewing angle is not ideal.

Front dual speakers

　　　 Lenovo Music Phone has a metal earpiece design at the top of the screen. At the same time, it is equipped with a 300,000-pixel front camera at the top left of the fuselage. In addition, you can see the light distance sensor and Lenovo trademark. At the bottom of the screen, we found that Lenovo Music Phone is not equipped with physical buttons, but virtual buttons are set in the screen. In addition, the front dual speakers are arranged at the bottom of the front of the fuselage, which can ensure excellent audio-visual entertainment playback effect.

Back: white high-gloss paint highlights fresh and beautiful.

　　　 Let’s take a look at the back of the fuselage. The back of the pearl white version of Lenovo Music Phone is made of white high-gloss paint plastic, which will make people feel a crystal clear and white as porcelain. In terms of details, the side of the mobile phone is embellished by the matte NCVM (electroplated) middle frame, which also highlights the aesthetic feeling of the mobile phone in fashion. In addition, although Music Phone has a huge body, its thickness is only 9.9mm, which undoubtedly reflects Lenovo’s pursuit of the ultimate side of the product.

Actual combat: carrying/talking/holding renderings

　　　　In order to show the actual operation experience of Music Phone more intuitively. We have also drawn up several scenarios for actual combat demonstration. The first is the portability test. The author tries to put it in an ordinary trouser pocket, and we can see that the user can carry it normally. Because the fuselage is relatively large, it is inevitable to put it to your ear during the call, which will lead to a high return rate.

Can be put in the trouser pocket completely.

It is difficult to press the leftmost button with one hand.

Hold hands and play horizontal screen games.

　　　　The size of LePhone mobile phone is 142x78x9.9mm, and its weight with battery is 197 2g. For female users, this weight is a little heavy, so it is recommended to use both hands to operate. However, for male users, this weight can make them have a more stable grip. In addition, when we hold the mobile phone horizontally, the prominent part of the palm rest at the bottom of the mobile phone can play an advantage, and holding it in our hands can avoid blocking the front double speakers.

System: Le Magic Android 4.0 do whatever you want

　　　　In addition to the large screen and ultra-thin 9.9mm body, another major feature of Lenovo Music Phone is that it has built-in the latest Le Magic Android 4.0 operating system. Compared with the previous Android2.3, the freedom of setting content is higher. In addition, the most familiar four-leaf clover main interface has become a small plug-in window, and users can choose whether to stay or not.

　
Screen Lock Interface/Clover Plug-in

　　　 In the unlock interface of Music Phone, we were surprised to see the display of weather animation effect. Generally speaking, the design of unlocking interface is still close to native. We can not only quickly enter the main interface, but also choose to turn on the camera module.

　
Change the shortcut key of four-leaf clover/main interface display

　　　 After entering the main interface, you will see the classic four-leaf clover plug-in. Although it has become a plug-in, we can still set various shortcut programs on the four-leaf clover. The icon design is still circular, but we have clearly seen that the overall operating style of the main interface is closer to the native Android4.0.

　
Select Widget/Application List

Interface: Desktop settings to create personalized UI.

　　　 The drop-down menu will display various notification items, and also support quick opening of common functions. In the application, we will see all the applications, and we can also add practical desktop plug-ins to widgets. It is worth mentioning that when we click the thumb on the right side of the widget, the system will also select your favorite application and recommend it to you. Of course, this requires us to operate in a networked environment.

　
Drop-down menu/widget

　
Recommend user’s favorite application/desktop menu settings.

　　　 Clicking the menu key on the desktop will bring up various commonly used function options. Music Phone provides a variety of themes and can be switched freely. The desktop setting is a highlight of Le Magic4.0 Android interface. This includes theme settings, scene settings, personalized settings, special effects settings and advanced settings. If you are good at creating personalized systems, you might as well work harder here.

Application Details/Store Classification

　　　 As a resource station promoted by Lenovo, Music Store is mainly divided into two parts. The first part is about providing resources, which are listed in the form of recommendation, ranking, classification and special area. The download interface will cover application screenshots and introduction content. However, in order to meet the needs of users, Lenovo also added interactive communities to music stores, allowing users to freely comment.

　
Le security/super tool

　　　　The popularity of smart phones has also made mobile phones a privacy tool for users. Therefore, how to protect your important information is the most important thing. Le Security can not only intercept harassing phone calls and filter spam messages, but also actively intercept charging behavior and set corresponding security permissions for its own applications. In addition, if you still don’t trust your information, you can also use the Backup Recovery program to back up the information to the SD card, including contacts, information, call records and applications.

　
Music Phone backup and recovery function

　　　　Music service is a set of service system provided by Lenovo for users. If users encounter problems, they can find answers in frequently asked questions. At the same time, we can also check the latest Lenovo official news in the information announcement. The testing center allows users to carry out detailed testing on all parts of the mobile phone, which provides a guarantee for providing good after-sales service.

Entertainment: HD video test/5 megapixel sample

　　　 Next, we tested the audio and video playback function of Lenovo Music Phone. Since it’s a big screen, it’s still unique to watch high-definition movies with it. We tested 720p video, 1080p video and playing movies with our own. The results show that 720p video can be played very smoothly, but 1080p video can’t support it. Under the condition of connecting to the network, the playback effect of Youku is also very ideal.

　　　 Like many Android4.0 devices, Lenovo Music Phone can also experience a variety of camera functions in the Android4.0 system after upgrading the system. This 5 megapixel camera supports autofocus and digital zoom, and also adds HDR camera mode, which can take better photos in backlight environment.

　　　 Judging from the photo proofs, the color reproduction degree of the photo is still ideal, and the white balance and sharpness are also more accurate. In addition, when shooting an object at close range, we will see that the noise is better controlled in the picture.

Performance: 1GHz processor running minutes/battery life summary

　　　 In terms of hardware configuration, Lenovo Music Phone is equipped with a 1GHz MT6575 processor and a PowerVR SGX 531 GPU, supplemented by 512MB of memory. In addition, the device is also equipped with an Android4.0 customization system and a WVGA resolution screen. The following is the result of running scores. It can be seen that the performance of the device in the graphical performance test of Neocore is very outstanding, which also shows its strength in multimedia audio and video playback and games.

　　　 AnTuTu（）

　　　 AnTuTu, a super rabbit system evaluation, is specially designed for Android system, and the hardware of tablet computer runs away. It can run a complete test project with one click, and pass many performance tests such as memory performance, CPU integer performance, CPU floating-point performance, 2D and 3D drawing performance, database I/O, SD card reading and writing speed, and score the overall and individual hardware performance of the mobile phone. At the same time, upload scores and check the ranking of the device in the world.

　
Music Phone system information

　
The running score is 3765.

　　　 The reason why AnTuTu’s achievement is put in the first place is that it can not only show the comprehensive strength of hardware, but also provide the breakdown results for reference. RAM indicates the throughput of the machine for data operation, integer/floating-point performance of CPU indicates the computing capability of the processor, 2D/3D drawing performance indicates the rendering capability of the graphics processing chip for images, database I/O performance indicates the access efficiency of the processor and RAM to the database, and SD card writing/reading speed indicates the read-write capability of the body ROM. (At present, this test requires ROM free space greater than 300MB, so if the body storage space /ROM is less than 300MB, this achievement will be ignored, but the total score will be achieved. Theoretically, the higher the score, the stronger the performance.

　　　 Vellamo

　　　 Vellamo is a benchmark application developed by Qualcomm (similar to Neocore), which allows you to test the performance and stability of, including Java script performance, rendering, networking and user interface. The result of this tool also includes several sub-items, but we only take the total score. The higher the score, the higher the optimization degree of mobile phone pairs and the better web browsing experience.

The performance test score of Vellamo browser is 1180 points.

　　　 Neocore

　　　 Neocore is a graphical performance benchmark software based on -ES 1.1. After the software is opened, an animation will be played. At the end of the animation, the software will evaluate the machine running the software and get an FPS value. The higher the value, the stronger the mobile phone hardware can handle dynamic images. Accordingly, the higher the screen resolution, the more pixels per unit area need to be rendered, and the greater the load on the graphics chip. In other words, in the case of the same graphics processing chip, the higher the screen resolution, the lower the Neocore value, and the two are in a trade-off relationship.

　
Neocore’s graphics performance test score is outstanding/supports 5-point touch.

　　　 Linpack

　　　 Linpack has become the most popular benchmark for testing the floating-point performance of high-performance computer systems in the world. The floating-point performance of a high-performance computer is evaluated by using gauss elimination to solve a system of linear algebraic equations with density of n degree in one variable. Compared with computers, the Linpack software of Android mobile phone version is relatively simplified, and the latest version only contains single-threaded and multi-threaded tests. As the name implies, the stronger the processor’s computing power, the higher the score. The advantages of dual-core and even future multi-core processors are reflected in the multi-thread testing part, and the test results are given in floating-point operations per second (Flops).

Lateral comparison of test results

　　　 In terms of battery life, Le Phone is equipped with a battery with a capacity of 2250mAh. At 100% power, after 8 hours of high-intensity testing (talking, surfing the Internet, video, running minutes and taking photos), the power is still 72%. Therefore, under normal use, the equipment should be able to reach a standby time of 2 days.

Evaluation summary:

　　　 The above is our all-round evaluation content for Lenovo Music Phone. In fact, overall, this product has achieved the effect of "surprise is greater than regret". Fashionable ultra-thin body, front dual speakers, 5-inch large screen, brand-new Le Magic Android 4.0 system and many Lenovo music services are all surprises. On the contrary, only using a 1GHz single-core processor and not equipped with a flash has become its small shortcoming. In addition, this mobile Phone also supports W+G dual-mode dual standby, and many third-party practical software are built in, so both business people and mobile phone players can feel the good experience brought by Music Phone. For consumers, if you don’t pay attention to the portability of the product and pay more attention to the big screen+multimedia entertainment experience, then the price of Music Phone is only 1999 yuan, which will be one of the good choices.

　　[Global Times-Global Network Report Special Reporter Yuan Hong] For a long time, the US Central Intelligence Agency (CIA) secretly implemented "peaceful evolution" and "color revolution" around the world, and continued to carry out espionage activities. The latest report released by the National Virus Emergency Response Center and 360 Company on the 4th revealed the main technical means of CIA planning and organizing a large number of "color revolutions" around the world, including a non-traditional regime change technology called "swarming" to promote young people connected through the Internet to join the mobile protest of "shooting a gun for a place".

　　The CIA is one of the main intelligence agencies of the US federal government. Headquartered in Langley, Virginia, the United States, it has four departments: Intelligence Department (DI), Secret Service (NCS), Science and Technology Department (DS&T) and Support Department (DS). Its main business scope involves: collecting intelligence information of foreign governments, companies and citizens; Comprehensive analysis and processing of intelligence information collected by other American intelligence agencies; Provide national security information and security risk assessment opinions to senior decision makers in the United States; Organize, implement, guide and supervise cross-border secret activities according to the requirements of the President of the United States.

　　The first part of this series of reports indicates that since the 21st century, the rapid development of the Internet has provided new opportunities for the CIA’s infiltration, subversion and sabotage activities. Organizations and individuals who use American Internet equipment and software products around the world have become the puppet "agents" of the CIA, helping the agency to quickly become a "star" in the cyber espionage war.

　　No matter the attempted "color revolution" in Ukraine in 2014, the "sun flower revolution" in Taiwan Province, China, the "saffron revolution" in Myanmar in 2007 and the "green revolution" in Iran in 2009, they can’t get rid of the influence of American intelligence agencies. According to statistics, for decades, the CIA has overthrown or attempted to overthrow at least more than 50 legitimate governments of other countries (while the CIA only admitted 7 of them), causing unrest in relevant countries.

　　Comprehensive analysis of all kinds of technologies in the above incidents, information communication and on-site command have become the decisive factors affecting the success or failure of the incident. These technologies in the United States are in a leading position in the world, which provides unprecedented technical possibilities for the American intelligence department to launch a "color revolution" abroad. Reports from the National Virus Emergency Response Center and Company 360 disclose five methods used by the CIA.

　　The first is to provide encrypted network communication services.In order to help protesters in some countries in the Middle East keep in touch and avoid being tracked and arrested, American companies (allegedly with American military background) have developed a TOR technology ("onion" routing technology) that can access the Internet and is untraceable. Related servers encrypt all the information that flows through them, thus helping specific users to access the Internet anonymously. After the project was launched by American enterprises, it was immediately provided free of charge to anti-government personnel in Iran, Tunisia, Egypt and other countries, so as to ensure that those "dissident youths who want to shake the rule of their own governments" can avoid the scrutiny and surveillance of the legitimate local governments when participating in the activities.

　　The second is to provide off-line communication services.In order to ensure that anti-government personnel in Tunisia, Egypt and other countries can still keep in touch with the outside world even when the Internet is disconnected, Google and Twitter companies in the United States quickly launched a special service called "Speak2Tweet", which allows users to dial and upload voice messages for free. These messages are automatically converted into tweets and then uploaded to the network, and released publicly through Twitter and other platforms to complete "real-time reporting" of the incident scene.

　　The third is to provide on-site command tools for assemblies and processions based on the Internet and wireless communication.The RAND Corporation of the United States spent several years developing a non-traditional regime change technology called "swarming", which was used to help a large number of young people connected through the Internet to join the mobile protest of "shooting one gun for another place", greatly improving the efficiency of the on-site command of the event.

　　Fourth, American companies developed a software called "Riot".The software supports 100% independent wireless broadband network, provides variable WiFi network, does not rely on any traditional physical access mode, does not need telephone, cable or satellite connection, and can easily avoid any form of government monitoring. With the help of the above powerful network technology and communication technology, the CIA has planned and organized a large number of "color revolution" events around the world.

　　Fifth, the State Council, USA, takes the research and development of anti-censorship information system as an important task.And invested more than $30 million in the project.

　　Specific to a number of typical cyber attacks in China, during the investigation, the National Virus Emergency Response Center and 360 Company captured and successfully extracted a large number of Trojan horse programs, functional plug-ins and attack platform samples closely related to the data of "Vault 7" of the Central Intelligence Agency (CIA). According to our reporter’s further understanding, the public security organs have followed up on this matter. This newspaper will continue to pay attention to the progress of this matter.

　　Through further technical analysis, the National Virus Emergency Response Center and 360 Company found that although the backdoor programs and attack components of CIA mostly run in the form of memory resident execution without physical files, it is extremely difficult to find and obtain evidence of relevant samples. Even so, the joint technical team successfully found an effective way to solve the problem of obtaining evidence, and found nine types of attack weapons used by the CIA, including attack module delivery, remote control, information collection and theft, and third-party open source tools.

　　Among them, the joint technical team accidentally extracted an information stealing tool used by the CIA, which belongs to one of the 48 advanced cyber weapons that exposed the confidential document Ant Catalog of the National Security Agency, and is a special information stealing tool of the National Security Agency. This situation shows that the CIA and the NSA will jointly attack the same victim, or share cyber attack weapons with each other, or provide relevant technical or human support. This adds new and important evidence to the attribution of the identity of APT-C-39 attacker. In 2020, 360 Company independently discovered an APT organization that had never been exposed by the outside world, and numbered it as APT-C-39. The organization specializes in cyber attacks and stealing secrets against China and its friendly countries, with victims all over the world.

　　In addition, the power and harm of CIA attack weapons can be seen from the third-party open source tools. This kind of attack means that the CIA often uses ready-made open source hacking tools to carry out attacks. The initial attack of CIA cyber attacks is usually carried out against the victim’s network equipment or server, and social engineering attacks are also carried out. After obtaining the target authority, it will further explore the network topology of the target organization and move horizontally to other networked devices in the intranet to steal more sensitive information and data. The controlled target computer will be monitored in real time for 24 hours, all the keyboard keystrokes of the victim will be recorded, the copy and paste information of the clipboard will be stolen, and the insertion status of USB devices (mainly mobile hard disks, U disks, etc.) will be monitored in real time. Once a USB device is connected, the private files in the victim’s USB device will be automatically stolen. When conditions permit, the camera, microphone and GPS positioning equipment on the user terminal will be remotely controlled and accessed.

　　Through empirical analysis, the latest report finds that CIA cyber weapons use extremely strict spy technical specifications, and all kinds of attack methods echo and interlock. Now it has covered almost all Internet and Internet of Things assets in the world, and can control other countries’ networks anytime and anywhere and steal important and sensitive data from other countries, which undoubtedly requires a lot of financial, technical and human resources support. American-style cyber hegemony can be seen, and the "matrix" deserves its name.

　　In view of the highly systematic, intelligent and covert cyber attacks launched by CIA on China, it is particularly important for domestic government agencies, research institutes, industrial enterprises and commercial institutions to quickly "see" and deal with them at the first time. The report suggests that in order to effectively deal with the imminent network and real threats, we should organize the self-inspection and self-inspection of APT attacks as soon as possible while adopting self-controlled domestic equipment, and gradually establish a long-term defense system to achieve comprehensive and systematic prevention and control and resist advanced threat attacks.

On January 13th, the 40-day Spring Festival travel rush 2017 was launched, which is also the earliest Spring Festival travel rush in recent five years. The passenger flow is still dominated by students, workers and visiting relatives, and it is expected to show the characteristics of "concentration at both ends of the festival and dispersion in the middle". The local railway and highway departments issued the Spring Festival travel rush Plan and took measures to ensure the smooth and safe travel in Spring Festival travel rush.

In the first 11 months of this year, the total import and export value of goods trade in Sichuan was 922.05 billion yuan, ranking eighth in the country, with an increase of 8.2% year-on-year, and the growth rate ranked fourth among the top ten foreign trade companies in China. Among them, exports were 565.85 billion yuan, up 11.9% year-on-year; Imports reached 356.20 billion yuan, up 2.9% year-on-year. This is what the reporter learned from Chengdu Customs on December 12th.

Since the beginning of this year, Sichuan’s foreign trade has overcome many unstable and uncertain factors and maintained steady growth. Among them, the import and export volume in November was 95.49 billion yuan, up 4.1% from the previous month. This is the second time that our province has exceeded 90 billion yuan in a single month this year after October, and the monthly import and export scale has reached a new high in the year.

In the first 11 months, the market vitality of private enterprises in Sichuan was further stimulated, with import and export of 308.43 billion yuan, up 34.7% year-on-year, 26.5 percentage points higher than the growth rate of the whole province, and the proportion of Sichuan’s foreign trade increased to 33.4%. The number of private enterprises engaged in import and export has also increased significantly. In the first 11 months, there were 6,244 private enterprises with import and export performance in Sichuan, an increase of 704 over the same period of last year, and the endogenous power of trade has been continuously enhanced.

It is worth mentioning that the import and export scale of Leshan and Meishan exceeded the 10 billion mark for the first time this year. In the first eleven months, driven by their respective advantageous industries, the import and export scale of Meishan and Leshan reached 10.52 billion yuan and 10.15 billion yuan respectively, up by 41.1% and 27.6% respectively.
