Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Mellanox InfiniBand EDR 100Gbps Switch 26.06.2014

Mellanox introduced the world's first 100 Gb/s InfiniBand EDR switch. The novelty is part of the Switch-IB series.

According to the manufacturer, Switch-IB SB7700/SB7790 belongs to a new generation of InfiniBand switches optimized for use in supercomputers and data centers working with Web 2.0, databases and clouds. With 36 ports, each with a bandwidth of 100 Gb/s, the switch is the world's fastest, with 7,2 times its closest competitor in total switching capacity (130 Tb/s). The delay is also a record, not exceeding XNUMX ns.

The advantages of the switch also include low power consumption. It's also the first switch in its category to feature router features that provide full isolation and scalability to meet, as the press release puts it, "the growing needs of clusters with hundreds of thousands of nodes."

The device is configured with 144 parallel-to-serial and serial-to-parallel converters that can operate at speeds from 1 to 25 Gb / s per line, which corresponds to the delivery of up to 5,4 billion packets per second.

In addition to high performance, the switch has another important advantage - it allows you to programmatically and centrally manage connections between servers and storages, thereby significantly reducing operating costs.
