SAMSUNG introduced the first DVD recorders

15.03.2005

The Russian representative office of "Samsung Electronics" presented a range of new products - DVD-recorders.

These are the first devices of this type in the company's lineup. Feature of all recorders is support of Multi-format of record: DVD-R/-RW/- RAM. The following formats are also supported: DVD-Video, DVD-R/-RW/-RAM, CD-DA/-R/-RW, MP3, JPEG. There are DV, RCA, S-Video connectors on the front panel of each device. The DV digital output will allow you to copy the film captured on the camera in digital quality directly to DVD. Each recorder comes with a 9,4 GB DVD-R AM disc that can record up to 12 hours of video.

The "Smart RP" processor has been specially developed for Samsung's new recorders, allowing recording to start at the touch of a button. The DVD-R100E and R100EA models open the line. Next comes the DVD-VR300 combo recorder. The DVD-R100 and DVD-R100EA models differ only in the different front panel design and support for the Show View function in the latest model (100EA).

The second model is DVD-VR300. The main feature of this device is the possibility of two-sided copying between DVD and VHS.

On store shelves, these models will be available at a price of about $400 for the R100 and $500 for the VR300.

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 ... >>

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, ... >>

Exploration of lightning inside a thundercloud 30.08.2023

The study of intra-thunderstorm processes was made possible by a daring mission by NASA pilots who flew a science plane into the heart of a lightning storm to record gamma-ray bursts.

Thunderstorms are powerful atmospheric phenomena that generate intense vertical flows of air and water, accelerating them to significant speeds. When the ice crystals collide in these swirling currents, they donate their electrons, creating electric fields that create lightning. Under certain conditions, these electrons can generate short bursts of gamma rays - the shortest and most energetic emissions in the electromagnetic spectrum. Such thunderstorms can generate two different types of gamma rays: short gamma ray bursts and long gamma ray bursts that last from a few minutes to several hours.

An international team of scientists traveled on a NASA ER-2 (Earth Resources 2) science plane, climbing up to 18 kilometers to get as close as possible to thunderclouds. This allowed the team to conduct a detailed analysis of gamma radiation and thunderclouds from airspace, which has its own significance.

The data obtained within the framework of this program contribute to a deeper understanding of the processes in lightning storms and the generation of gamma radiation. Such an analysis could help scientists predict the intensification of storms and provide more time to warn the public about possible lightning.

The NASA ER-2 science aircraft used in this study is one of two in the agency's arsenal. ER-2 is capable of operating at great altitudes, exceeding 99% of the Earth's atmosphere. They were based on the Lockheed U-2 reconnaissance aircraft and were acquired by NASA in 1981 and 1989, respectively.
