Hangzhou City Brain Releases AI Vision Products - part 1

On April 8th, the City Brain released the AI product Scorpio, upgraded the monitoring dome intelligent perception system, and provided the city's large-scale real-time cameras with real-time analysis capabilities through automatic tracking recognition and intelligent perception technologies. The use efficiency is further broken through. The traffic accident can be found in only 20 seconds and the accuracy rate was over 95%. It truly replaces traffic police patrols with machine vision.

In order to solve the problem of traditional traffic patrols, Hangzhou City Brain attaches great importance to video intelligent analysis technology and will become the eye of the city's running state in the future. In the fields of target detection, tracking, scene segmentation and behavior identification, they have achieved a number of technological breakthroughs and innovations. It is like a huge smart gsm alarm system at your home. In particular, in pedestrian and non-motor vehicle testing, the Hangzhou City Brain machine vision team has finally launched the mature vision product Scorpio.

20 seconds recognition with an accuracy of 95% or more

In terms of the scene, "Scorpio" possesses comprehensive traffic incident identification capabilities, autonomously identifies different scenes such as intersections, road sections, motor vehicle lanes, non-motor vehicle lanes, and crosswalks in urban roads, and accurately identifies motor vehicles from dynamically changing mixed traffic. Traffic participants such as non-motorized vehicles and pedestrians can realize automatic recognition of various types of traffic anomalies such as congestion, reverse driving, non-motorized vehicles and motorized lanes, and can adapt to the working environment at night in low light conditions. The system can detect traffic jams in a timely manner, calculate the duration of congestion, and discover traffic accidents and non-motorized illegal driving.

In terms of immediacy and accuracy, Scorpio took only less than 20 seconds from the event to the alarm, and the accuracy rate was over 95%, providing strong support for early detection and early disposal.

Why is the solar panel called “the great invention”? - part 2

It gives energy security

Whether a home is on the grid or completely off-grid, solar panels provide energy security. Those on the grid will have to pay for the energy they use outside their solar power, which means they pay the utility. These prices fluctuate based on a range of factors, including political influences. In addition, being on the grid does not guarantee the safety of the power supply. In fact, power outages continue to be common in many parts of the country, leaving people facing blackouts. The sun, however, has no political agenda and does not require payment. It will just get up and shine every day.

It makes you more independent

Once again, the sun has no program or allegiance. It does not matter if we are at peace or at war. The sun will not cut off its ray supply when a government irritates the government of another country. Not only that, oil and gas are finite resources, while sunlight is not.

His operation is silent

Power plants and generators, and even green technologies such as wind turbines, heat generators and hydro devices, are extremely noisy. Solar panels, on the other hand, make no noise. The energy comes simply from the sun, which they harness and deliver to you.

You do not need a lot of space

You do not need to have a huge roof to take advantage of the use of solar panels. In fact, you do not even need a roof (although it's better because of obstructions). Roofs are popular because they receive a lot of sunlight, but you can literally mount the panels on just about anything. One of the coolest features of the solar panel is that it is relatively small, so you can actually be creative in terms of how and where to mount them.

It protects your roof

If you install your panels on your roof, you must first make sure they are in good condition. Once the panels are installed, they also offer some degree of protection to your roof. This is because they will create a protective barrier, stopping the heat, stormy weather and sunlight, hitting the roof directly. Many people have reported that the insulation of their property has improved since the installation of solar panels. This means that their home stays cool in the summer, while warming up in the winter, while being able to lower the heating.

Why is the solar panel called “the great invention”? - part 1

When you look at the solar panels, they all appear the same. However, there are many features to consider. Unfortunately, it is not possible to say that some features are better than others because everything depends on the circumstances. For example, some features work very well in hot climates, but do not do anything colder. Similarly, some features greatly increase the price of the panel, which makes you wonder if they are really worth it. At the end of the day, you need to know how to buy smart, and that means understanding the different features you can find in residential solar panels and the ones you really need. At the same time, there are certain features that all the good solar panels have that you absolutely must look for.

The main features of solar panels allow you to save on your energy bills while making a positive contribution to the environment. However, there are a number of other unique features, and these are the ones that make these panels so attractive to residential properties. This is especially true for people who want to be independent and have energy security. Let's take a look at the key features, which are typically unique to the solar panel.

A recognized brand name

Wanting a recognized brand is a good advice, but it's tricky. If you see brands like Sun Edison, KCASA, Sunpower, Sanyo and Sharp, you are guaranteed to have good quality. However, you will also pay a higher price. Brands like Kyocera and Canadian Solar are also very good. Thus, you will have to spend time reviewing the different brands and comparing their prices.

Low maintenance

Solar panels do not require much maintenance. Once they are installed, you only have to maintain them once a year, after which they will be cleaned. This will ensure that the panels will continue to function properly. There are no moving parts on the solar panels, and they are very durable. Therefore, very little maintenance is needed.

They are a constant and consistent source of energy

The sun will rise every morning, and it will set every night. It's so consistent that we know, by the minute, when that will happen. We understand the sun so well that we can use it to project seasonal sunlight and predict weather. This means that it is possible to know exactly when there will be a lot of power, and therefore when we should use some of our equipment.

Trappist-1 planetary system: our next home?

In February last year, scientists announced the discovery of seven terrestrial planets running around the dim dwarf star - "Trappist-1". So far, this has not only been the star system that found the largest number of planets in the same type, but also three of which are operating in the star's livable belt. Now a new study shows that some planets inhabitable in the planetary system may exist in support of extraterrestrial water. Using an observational data from the NASA Hubble Telescope, an international team estimated that the heat and ultraviolet radiation from the central star over the past eight billion years might affect the water volume of these planets.

About 40 light-years away, TRAPPIST-1, a red dwarf star is inspiring more research enthusiasm among scientists, and now they are making greater efforts to learn more about this extrasolar planet system. Scientists' models show that the planet closest to Trappist-1 may have changed from a watery world to a hotter area, losing more than twenty times as much water as the Earth's oceans. According to the model, planets in so-called "livable zones" may lose even less water. And, billions of years later, their surface and interior may have residual moisture.

The TRAPPIST-1 has a surface temperature of about 2500 Kelvin, about 8% of the mass of the sun, 11% of the sun's radius, and has at least 500 million years of life, with trillions of years remaining to come. Our solar has the life of about 4.6 billion years, and about 5 billion years later, it will evolve into a red giant with the surface temperature of about 5778 Kelvin. Seven planets are likely to be tidally locked, that is, just as the moon is locked by the Earth. Just like our planet Earth, the seven planets are always facing the main star by the same side. The TRAPPIST-1h orbit, about 9.3 million kilometers from the central star, is about 6% of the Earth's day-distance. Although this distance is too close to the solar system, it provides a moderate surface temperature here - minus 104 Celsius (169 Kelvin) because the luminosity of its central star is only one in two-thousandth of our sun. Therefore, the surface of TRAPPIST-1h is likely to be a frozen world.

Temperature and humidity are essential to human life. Living in the suitable environment with comfortable temperature and humidity is important to our health so having a high-quality Digital LCD Hygrometer Thermometer is necessary. With the Digital LCD Hygrometer Thermometer, we will able to know the exact weather every day so that we can be better prepared.
