New use for Blu-ray discs

12.10.2012

Japanese companies Memory-Tech, krypton, Q-tec and Camerata Tokyo intend to offer the market a new "format" of audio discs, which uses Blu-ray discs as a medium. These manufacturers have formed an alliance called "Promotion Group of Blu-ray Disc for High Resolution Audio", which will promote the development.

The new discs will use 96kHz/24bit or 192kHz/24bit encoding with Linear PCM (uncompressed) to store sound recordings. The main advantage of Linear PCM - high quality, free from loss associated with compression. The main disadvantage is the large consumption of disk space.

The new discs will be compatible with existing BD players and recorders. Taking into account that in the BD Video standard it is obligatory to support only 96 kHz sampling rate, and 192 kHz is an option, one and the same recording will have to be placed on discs in two versions.

The members of the alliance are going to offer record companies complete sets of equipment for creating and replicating new discs. Camerata Tokyo plans to release the first three albums in the new format in November. They are expected to be no more expensive than SACD editions.

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 ... >>

How to understand a dog 30.12.2013

The Swedish research company The Nordic Society for Invention and Discovery (NSID) has announced a desire to create a device that will allow the owner of the dog to know what his pet is thinking.

No More Woof consists of an electroencephalograph, a decoder and a speaker. All parts are fixed on a special device that is put on the dog's head. The electroencephalograph reads the electrical signals from the animal's brain and sends them to a decoder, which matches the signal with a set of pre-recorded audio recordings. The appropriate audio recording is then played back on the speaker.

According to NSID representatives, they have learned to recognize the electrical signals responsible for hunger, fatigue and curiosity. When pets feel hungry, the speaker will play "I'm hungry," when tired, "I'm tired," and so on. The company claims to be able to recognize other signals, but did not specify which ones.

"It should be noted that dogs think differently than humans. And if signals appear in the brain of a dog that speak of hunger, this does not mean at all that he "thinks" about it. Rather, this is a mental state than a thought. As for the difference between these concepts, let philosophers think about it," the authors of the project said.

The company assures that not a single dog has been harmed and will not be harmed during the research, and also emphasizes that the project is at a very early stage, so for now there is no need to show any special expectations for it.

The authors of the project posted it on the Indiegogo crowdfunding site, hoping to attract funds from ordinary people to the project. The fundraising campaign started on December 16 and will end on February 14, 2014.
