BMW car will pass a pedestrian

26.05.2014

The automotive company BMW Group is engaged in the UR:BAN research project, within which it develops driver assistance systems. The goal of this initiative is to move efficiently in dense urban traffic and ensure the safety of motorists, pedestrians and cyclists.

The German abbreviation UR:BAN stands for "Urban Space: User-Oriented Assistance Systems and Network Management". Launched in 2012 and running through 2016, the project has 31 participants, including automakers and their suppliers, electronics and software developers. The research initiative is sponsored by the German Federal Ministry of Economics and Energy.

As part of UR:BAN, BMW is creating an electronic assistant that, using sensors and built-in cameras, can analyze the actions of cyclists and pedestrians in the vicinity of a moving car. As soon as there is a risk of a collision with a person, the system is activated: the driver receives a warning signal, and if necessary, the electronics slow down the vehicle, stop it or automatically perform a maneuver if it is possible under current conditions.

According to the developers, at the moment the system can recognize the movements of a person's body parts to determine the direction in which he is going or is going to go. Popular Volvo models have previously learned to "see" pedestrians and cyclists on the road.

Another focus of BMW's work is the Green Coordination and Deceleration Assistant system, which makes the movement of cars in the city more efficient. This technology, taking into account the current traffic congestion and information about the signals of nearby traffic lights, advises drivers on the optimal speed and route, and also optimizes engine performance, making it more productive and economical.

In certain situations, the electronic assistant will offer not the shortest, but the fastest route, requiring fewer stops at intersections. Such a feature, according to BMW, will be extremely useful for electric and hybrid vehicles.

Previously, cars with traffic lights linked Honda and Audi. Such developments are designed to make road traffic efficient, reduce fuel consumption and environmental damage.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

paper battery 19.01.2023

Scientists from Singapore have learned how to make batteries from household waste that are twice as good as those used by modern smartphones.

Nanyang Technological University has developed a new method to process disposable paper packages, bags and cartons into electrodes for rechargeable batteries. The researchers used a laser to cut paper waste into thin sheets with gratings of various shapes, then they were heated to 1200 degrees Celsius in a special furnace without a flame. As a result, paper turned into pure carbon, water vapor and oils.

The scientists turned the extracted carbon into electrodes, and the resulting cells showed superior durability, flexibility, and electrochemical properties associated with the structure of paper fibers.

Laboratory tests have shown that a battery with such an anode can withstand up to 1200 charge and discharge cycles - twice as much as modern smartphone batteries. In addition, they are five times better able to withstand physical exertion by absorbing shock.

The Singaporean researchers have filed a patent for their technology with NTUitive, NTU's innovation and enterprise company, with a view to bringing it to the commercial market in the future. Carbonization of paper, in their opinion, occurs without burning oxygen, so some carbon dioxide is released.
