Weeding video camera

06.03.2011

Norwegian engineers have created a "smart" sprayer that, using video cameras equipped with image recognition software, recognizes weeds and sprays herbicide only on them, and not on cultivated plants. Chemicals are saved and environmental pollution is reduced.

Before processing the bullet, photographs of the most common weeds in a given place must be stored in the memory of the device.

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 ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

The updated line of Wireless Plus from Seagate 06.05.2014

Seagate Technology has announced a new milestone in the development of wireless storage systems. Seagate Wireless Plus mobile storage devices are now available in 500GB, 1TB, and 2TB. In addition, Seagate Wireless Plus now boasts several more features, such as the ability to save content and files remotely using the updated Seagate Media app, as well as the option to move files to cloud services such as Dropbox and Google Drive, Seagate told CNews.

According to the company, the Wireless Plus solution was designed to enrich the capabilities of mobile devices, including smartphones and tablets. Seagate mobile storage is accessed through the Seagate Media app, optimized for iOS and Android operating systems, as well as KindleFire HD and Windows 8 tablets. The Seagate Media app now lets you sync files on your Seagate Wireless Plus with your existing cloud services, which ensures constant, uninterrupted access to files even without a network connection. "Seagate Media creates its own folder in Dropbox or Google Drive, and as soon as you connect to the network, your files are automatically synchronized so that no changes and updates are 'lost' either in the 'cloud' or on the Wireless Plus drive itself," explained at Seagate.

Seagate Wireless Plus connects to mobile devices using Wi-Fi, which itself distributes, working on battery (the Wireless Plus battery can provide up to 10 hours of device operation). It's easy to connect to the device - just find Wireless Plus in the list of available Wi-Fi networks. The solution creates its own Wi-Fi network, so it is not necessary to connect to third-party networks for full-fledged work, the company emphasized.

At the same time, Wireless Plus can be used to watch videos, photos, music and documents on the big screen using Apple Airplay, DLNA or an app designed specifically for Samsung Smart TVs and Blu-ray players.

"Cloud services provide users with a convenient way to share files with friends and colleagues. With the new Seagate Media app and Wireless Plus device, users will be able to use the cloud to access even more data from their Wireless Plus device," said Scott Horn (Scott Horn ), Vice President of Global Marketing at Seagate.

The Seagate Wireless Plus is available today for a suggested retail price of $199,99 for 2TB and $179,99 for 1TB. The 500GB drives will be available for purchase on the Seagate website starting May 9 this year for $149,99, and can be pre-ordered today.
