Blinking of the magician and his audience 19.05.2024

Magic and illusions have always captured the attention of the public, but what happens behind the scenes of the magician and in the brains of his audience? Scientists from the UK decided to solve this mystery by conducting a new study involving ten illusionists of varying experience. Illusionists, some of whom had been practicing magic for more than half a century, others for only six months, were invited to demonstrate the same trick - the popular coin trick. Recordings of their performances during training and on stage showed that each of them began to blink significantly more often at the moment of performing the trick. The study's findings indicate that magicians' blink rate may be related to unconscious aspects of their performance. At the same time, as scientists have found, spectators also begin to blink more often, following the movements of the illusionist. This observation supports the idea that magicians may be catalysts for blinking in audiences. Additional research has shown that magicians blink more often during ... >>

Ultrasonic coffee machine 19.05.2024

Iced coffee has become an integral part of coffee culture in recent years. Therefore, engineers from the University of New South Wales decided to improve its preparation. They have developed an ultrasonic coffee machine that reduces the cold brew time for ground coffee beans from 12-24 hours to significantly less time. Iced coffee, or "Cold brew", is popular due to its smoothness, low acidity and low bitterness. It is prepared by steeping ground coffee in cold water for a long time. Unlike traditional hot brewing, which often imparts bitterness to coffee, cold brewing extracts more delicate and complex flavors from the coffee beans. The innovative system, presented by a team of engineers, introduces ultrasonic technology into the coffee preparation process. The system uses ultrasonic waves to speed up the process of extracting oils, flavor and aroma from ground coffee. This allows you to significantly reduce the time ... >>

The speech of sperm whales is similar to that of humans 18.05.2024

In the world of the ocean, where the mysterious and unknown coexists with the studied, sperm whales, with their huge brains, are of particular interest to science. Researchers, working with a huge array of audio recordings collected during the Dominica Sperm Whale Project (DSWP) - more than 8000 recordings, seek to unravel the secrets of their communication and understand the structure and complexity of the language of these mysterious creatures. By studying in detail the recordings of 60 sperm whales in the eastern Caribbean, scientists have revealed surprising features of their communication, revealing the complexity of their language. "Our observations indicate that these whales have a highly developed combinatorial communication system, including rubato and ornaments, which indicates their ability to quickly adapt and vary during communication. Despite significant differences in evolution, sperm whales have elements in their communication that are characteristic of human communication," says Shane Gero, a biologist at Carleton University and director of the CETI project.

Indoor navigation 19.07.2017

ZTE Corporation announced the launch of its Indoor Intelligent Navigation, Smart Car Seeking solution.

The solution provides seamless outdoor and indoor navigation, smart vehicle location and Open Service System (COS). Using QCell indoor coverage solution, mobile edge computing (MEC) technology and IoT-based magnetic induction object detection engine, the solution for intelligent management of indoor parking (both for parking lots with a lot of parking spaces and for multi-level parking lots) requires low cost and high efficiency.

The solution allows the operator to build a modern, user-friendly and smart building by establishing a stable connection between the objects in the solution.

The use of navigation devices when driving on the street has already become an integral part of our daily life, but finding a free parking space in an underground parking often takes quite a long time. To cope with this task, ZTE's solution for organizing "smart" navigation and determining the location of the car indoors allows.

When an approaching vehicle is detected, the QCell interior coverage system automatically reports this to the MEC system. This ensures high accuracy of indoor navigation, guarantees the possibility of reserving a parking space and planning the route of the car.

Modern underground parking lots are often multi-level, and their area can exceed 10 thousand square meters. m. In such conditions, it is easy to get lost or forget exactly where the car was parked. The use of QCell allows you to track the route of the user's movement, and the mechanism based on IoT technology for detecting objects through magnetic induction determines movement algorithms, analyzes and remembers the parking place of the car.

To get detailed information about the exact location of their car and how to get to it, the client, being in the internal parking lot, just needs to scan the QR code and click on "Navi." in a dedicated application. Thus, the driver no longer needs to remember the number of the parking space, the registration number of the parking zone or the route, now it is enough to turn on the navigation and follow the system's instructions in real time.
