baby cry translator

04.07.2019

Developers from the USA decided that the crying of small children is not just an incoherent set of sounds and created a special baby cry translator that helps to recognize what children are trying to "tell" us.

In fact, everything is quite simple and the idea is not new at all, but one of the developers, a professor from the University of Northern Illinois, Lichuan Liu, relied on the experience of pediatricians in the process of creation.

"Experienced nurses or pediatricians can determine why a baby is crying. Specialists can do this based on their own experience. We spoke with many doctors and they confirmed that theoretically, there are some patterns in children's screaming and crying that can be used to create algorithms for translator." says Professor Liu.

Therefore, Liu and the team set out to identify the features of children's cries that signal the presence of pain or discomfort. These characteristics include differences in the intensity and frequency of crying or screaming. The team then developed an algorithm based on automatic speech recognition to detect and identify these features.

This "cry language recognition algorithm" was trained on recordings of infant cries taken from the neonatal intensive care unit. It uses a unique system that reconstructs the signal based on incomplete data (i.e., even if the system hears snippets of a scream, it can "think" what it would look like in its entirety and make a decision). This is necessary to identify sounds in a noisy environment.

The algorithm can identify children's crying against the background of, say, an adult's speech or even the loud sounds of a working TV. In addition, he is able to work in conditions where there are several kids in the room.

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 ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

V2V technologies for road safety 11.04.2014

The embedded vehicle market is growing due to the attention of the US government, although the exact timeline for the implementation of the initiative to implement V2V technologies in cars has not yet been announced.

Analysts note an increase in demand for embedded solutions for cars in the US, although it is difficult to give numerical estimates. They attribute this fact to the mandatory use of V2X technologies (Vehicle-to-X, from vehicle to object), developed by the government of the country.

The sooner the project is completed, the better, said Mak Kevin, senior analyst for Automotive Electronic Services at Strategy Analytics. First of all, he has in mind the development of wireless communication capabilities between two cars. The prospects and profit that V2V technologies (V2V, Vehicle-to-Vehicle, from vehicle to vehicle) can bring to the auto industry are huge, McKevin is sure. The main direction of development can be security. "Wi-Fi has long been used in the auto industry for infotainment applications," comments McKevin. "Security features can be added at a relatively low cost."

There have been many demonstrations of V2X security technologies: Pedestrian Detection by Honda America; demonstrated by General Motors, a system of interaction between the car and mobile devices of pedestrians, cyclists and road infrastructure. The latter alerts the driver to slowed down vehicles ahead, slippery roads, stop signs, and other potential problems. "The more people who use V2X technologies, the more powerful the breakthrough in the development of automotive safety systems will be," said Don Grimm, senior scientist in the division of vehicle recognition and control systems at General Motors.

Improving safety and preventing collisions and accidents is a key objective of the DSRC (Dedicated Short Range Communication) standard being developed by the US government, designed to solve the problem of rapid data exchange between cars and the transport infrastructure surrounding them. As CNews already wrote, according to preliminary estimates, V2X technologies are able to help prevent from 70% to 80% of accidents and save 20 thousand lives every year, not only in the United States.

By 2020, the volume of sales may reach 18,8 million V2X systems built into selected types of vehicles around the world (if the standard takes effect in the United States). The forecast becomes much less optimistic if the DSRC is not adopted. In this case, sales will amount to 5,3 million systems, according to experts from the British company Strategy Analytics. According to Anthony Foxx, the US Secretary of Transportation responsible for legalizing the new technology, no timeline has yet been set.
