Car simulator

11.01.2009

Models of new car models are always blown in a wind tunnel, but the blowing results are not completely reliable. Indeed, in real conditions, the wheels of the car rotate, the road runs under them, which makes certain changes to the flow pattern.

In North Carolina (USA), a wind tunnel was built with a running track made of a steel tape more than three meters wide, on which a car is placed. The track develops a speed of up to 290 kilometers per hour, which allows you to test racing cars.

A headwind with a force of up to five on the Beaufort scale is provided by a seven-meter fan. For an hour of purge, the owners of the device charge $ 4000.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Wearable sensor for taking vital signs 17.07.2014

In September 2014, Toshiba Corporation plans to begin deliveries of a specialized biological sensor Silmee Bar, designed to record vital signs of the body.

The sensor is fixed in the chest area with a helium pad. It allows you to take an electrocardiogram, register a pulse wave and body movements, and measure temperature. Based on the data obtained, various indicators are calculated, in particular, changes in heart rate are evaluated depending on the intensity of movements and changes in posture are recorded. Information can be transferred to a smartphone or tablet via Bluetooth wireless communication.

The sensor measures 64x28x9,6mm and weighs 14,6g. The battery is said to last approximately 24 hours of continuous use. IPX5/IPX7 certification means protection against moisture and dust.

It is assumed that the novelty will be of interest to various scientific organizations, universities and corporations conducting research in the field of medicine and health care.

Note that Toshiba considers the health care business as one of its top three business areas. It is expected that in 2015 financial year it will bring corporations up to 600 billion yens ($5,9 billion) of revenue. In 2016, revenue could rise to 720 billion yen.
