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 ... >>
| Random news from the Archive Intel neuromorphic nose
27.03.2020
Intel researchers, together with scientists from Cornell University, have created a kind of "electronic nose" that can remember the specific smell of a compound and chemical at a time and identify this smell with high accuracy even if it is masked by other strong smells. The "electronic nose" system is based on Intel's Loihi neuromorphic processor, and its sensitive element is a matrix of 72 chemical sensors.
The Loihi processor is programmed in such a way that its circuits mimic the neurons of the so-called olfactory bulb, the part of the brain that is responsible for smell recognition, as closely as possible. Further development of this system will make it possible in the future to create devices that can detect dangerous chemicals, hidden drugs or explosives, and, of course, make accurate medical diagnoses.
The architecture of the Loihi processor is built to closely match the work of neural circuits and more complex parts of the brain than can be achieved with conventional central processing units, even if equipped with special neuromorphic accelerators. Thanks to this, such neuromorphic processors are able to perform work that is beyond the power of traditional artificial intelligence systems. In addition, the amount of energy consumed by systems with neuromorphic processors is significantly less than the amount consumed by conventional systems that perform comparable tasks in the field of deep machine learning and self-learning.
One of the things that can be implemented on a neuromorphic processor, but is very difficult to do using traditional technologies, is the so-called one-shot learning. The human brain does this with ease, once you feel some kind of characteristic smell, the next time you will certainly recognize it. Artificial intelligence systems using neural networks require training on a huge number of examples, and the worst thing is that a previously trained neural network cannot be trained in a new category without damaging its memory of the previously learned category. To achieve the maximum result, the neural network must be completely retrained using data from all the necessary categories at once.
The next steps that the Intel and Cornell University researchers intend to take will be to make it possible to group related data (smells) into general categories. For example, the system is already able to recognize that the smell corresponds to the smell of strawberries grown in Europe or grown in California, but later it will have to indicate that both smells are the smell of strawberries.
