Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

New User Identification Methods 01.12.2013

Iowa State University engineers (USA) are working on innovative methods of data protection and user identification. They use individual typing patterns, as well as individual features when working with a computer mouse and mobile devices.

Associate Professor Morris Chang argues that each person has an individual style of typing on the keyboard or the manner of using a mobile phone, as well as a computer mouse. Researchers have given this process the name "cognitive fingerprinting." At this stage, the prototype of special software is already able to determine the difference in the rhythm of typing. In experiments conducted on 2000 users, the program was wrong only 0,5% of the time. These indicators are planned to be improved.

A feature of the system is that identification can be carried out without the knowledge of the user. At the same time, the system does not require additional hardware, the solution is implemented in software. When a "stranger" is detected, the identification system blocks it, blocking access to confidential information, or asks for an additional password to unlock it.

Most computers today only ask for a password when they log in. The new identification system will allow you to determine in the course of work whether the person continues to use the computer. In practice, this makes it possible to significantly improve the information security of private and corporate computer networks, as well as additionally protect mobile devices.
