New Voice over Internet (VoIP) Platform

30.06.2005

TEXAS INSTRUMENTS Corporation has implemented a new platform for the transmission of voice signals over the Internet (VoIP). This platform is implemented in the new digital signal processor TNETV2520.

Based on the TMS320C55x architecture, the TNETV2520 processor provides seamless voice and fax communication for traditional and packet telephony. Thanks to the large amount of internal memory, there is no need to connect an external memory.

The processor allows you to simultaneously process 64 channels with pulse code modulation, 32 channels using the G.729AB protocol and 24 channels using the G.723.1A protocol.

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, ... >>

How the brain remembers faces 29.12.2017

A team of scientists led by Doris Tsao, a biologist at the California Institute of Technology, using a combination of brain mapping and recording of individual neuron signals, appears to have cracked the neural code for facial recognition in primates. Scientists have found that the frequency of pulsation of each cell of certain areas of the face (face patches, and this is the term) corresponds to its individual features. Cells can "tune" to respond to bits of information like a system of scales, and then combine these bits in various ways to reproduce each feature of the seen "face" of the animal.

A study of the brain's ability to process images showed that several regions of the temporal lobe of the brain, the size of a blueberry, are responsible for face recognition.

To understand how cells perform this recognition function, Cao and Steven Le Chang took 2000 pictures of faces that differed in 50 features, including facial roundness, distance between the eyes, and skin tone and texture. They showed these pictures to two monkeys, recording the activity of individual neurons in three different facial patches of both animals.

It turned out that neurons respond only to one particular feature. Hippocampal neurons encode non-individual faces. Neurons divide facial images into small sections and encode certain features, such as the width of the hairline. Moreover, individual neurons also process additional information. Data from different parts of the face are combined to get a complete picture.

By understanding how this division of labor works, Chang and Cao were able to predict how neurons would react to a completely new face. They developed a mathematical model in which facial features were encoded by various neurons. They then showed the monkey an image of a face that it had not seen before. Using the created algorithm, scientists were able, based on the data obtained on the reactions of neurons, to digitally form an image of the face seen by the monkey. The reproduction turned out to be almost indistinguishable from the image that the monkey saw.
