Dell XPS 27 All-in-One PC

11.01.2017

Dell introduced the Dell XPS 27 all-in-one computer, which stands out visually for its sound system. On the front panel, under the screen, the manufacturer made six emitters - two high-frequency and four broadband. But four more, two broadband and two low-frequency, are hidden from view. As a result, the audio system produces 50 watts of power and, according to the creators, provides the best sound in devices of its class.

The system's sound was tuned by Jack Joseph Puig, music producer and Grammy Award winner.

Screens to match the sound. The XPS 27 only comes with 27-inch 4K IPS displays. Customers will be able to choose the type of panel: touch or conventional. Both matrices cover 100% of the Adobe RGB color space.

Interestingly, the monoblock uses not the latest seventh, but the sixth generation Intel processors: Core i5-6400 (2,7-3,3 GHz) and Core i7-6700 (3,4-4,0 GHz). They are accompanied by AMD video cards: AMD Radeon R9 M470X with 2 GB of GDDR5 memory and AMD Radeon R9 M485X with 4 GB of GDDR5 memory. The maximum DDR4 RAM is 32 GB.

The XPS 27 supports three drives: one M.2 SSD up to 1TB and two 2,5" HDDs up to 2TB. Also in the configuration of the device are Wi-Fi 802.11 ac and Bluetooth 4.0 adapters, a webcam with 720p video recording, an IR camera (it is located under the screen), five USB 3.0 ports, two USB-C ports with Thunderbolt 3 interface, HDMI connectors and DisplayPort 1.2.

Dimensions of new items - 625 x 435 x 80 mm, weight - 13 kg. A monoblock made in a metal case can already be ordered in the US at a price of $1500.

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 ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

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. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

Earth's inner core is moving in different directions 07.06.2022

Scientists from the University of Southern California, USA, have found evidence that the Earth's inner core is moving in different directions, which contradicts accepted theories, which suggested that the core constantly rotates at a higher speed than the surface of the planet.

A new study shows that our planet's inner core is changing speed and direction of rotation, as well as moving, as seismic data show.

"We think that the surface of the Earth is shifting relative to its inner core, and also that it rotates more slowly than the planet and can rotate in a different direction," says John Vidale from the University of Southern California.

The Earth's inner core is a hot, dense ball of solid iron about 2600 km in diameter. It cannot be seen directly, so scientists have used seismic data to learn about the speed and direction of its rotation, as well as its movement in the center of the Earth.

In the 90s of the last century, scientists suggested that the inner core of the Earth rotates faster than the planet itself. But a new study shows that the core is spinning more slowly than previously thought. The scientists also found that the nucleus can change the direction of rotation.

According to scientists, the inner core of the Earth does not stand still, but it moves and moves back and forth for a couple of kilometers and this happens every 6 years. Next, scientists plan to study the formation of the core and what other processes occur deep below the surface.

According to existing scientific concepts, the Earth's core consists of two parts: an inner solid core and an outer liquid core. It is believed that the temperature on the surface of the inner core is approximately 6 thousand degrees Celsius, and the density reaches 12,5 tons per cubic meter. So far, scientists have obtained all data on the core only through indirect observations, since it is currently not possible to get to the center of the Earth.
