Exploring fluid dynamics in virtual reality

Anything that moves through water or air leaves behind an invisible wake of swirls and waves. Flow visualization makes these “flow field” patterns visible to allow researchers to study them. Credit: Syracuse University Virtual reality has grown beyond the gaming world and is increasingly being used for a variety of applications—including education. Researchers in Assistant Professor Melissa Green’s Flow Visualization Lab in the College of Engineering and Computer Science are developing a way to apply it to their work. This…

North Korea and the Paradox of Nuclear Weapons

On Tuesday, Nov. 28, North Korea launched a new type of intercontinental ballistic missile (ICBM).  Analysis of the flight path and other data indicates that the new model, called the Hwasong-15, can probably reach any point in the continental U. S.   And last September, Kim Jong-un ordered a successful underground test of a thermonuclear weapon whose yield exceeded 100 kilotons of TNT, the standard measure of nuclear-weapon power.  While North Korea has yet to demonstrate the ability to deliver nuclear…

Voyager 1 fires up thrusters after 37 years — ScienceDaily

If you tried to start a car that’s been sitting in a garage for decades, you might not expect the engine to respond. But a set of thrusters aboard the Voyager 1 spacecraft successfully fired up Wednesday after 37 years without use. Voyager 1, NASA’s farthest and fastest spacecraft, is the only human-made object in interstellar space, the environment between the stars. The spacecraft, which has been flying for 40 years, relies on small devices called thrusters to orient itself…

Study finds drones more damaging than bird strikes to planes

Credit: CC0 Public Domain Drones that collide with planes cause more damage than birds of the same size because of their solid motors, batteries and other parts, a study released by the Federal Aviation Administration on Tuesday found. The study’s researchers say aircraft-manufacturing standards designed for bird strikes aren’t appropriate for ensuring planes can withstand collisions with drones. The FAA said it will depend on drone makers to help develop technology to detect and avoid planes. Reports of close…

How Technology Has Improved Education

Positive Effects of Technology on Modern Education Today, technology has become an integral part of our everyday lives and has drastically changed many areas of society in positive ways, including education. Technology has revolutionized the processes of teaching and learning and made them more easy, interesting, and enjoyable. Technology Enhanced Teaching and Learning Technological developments like computers, mind training software, digital cameras, 3D visualization tools, PowerPoint presentations are great tools for teachers to help students develop their cognitive skills such…

NASA advances concepts for next-gen aircraft

Credit: NASA An aviation renaissance, one focused on energy efficiency and economic impact, is on the horizon, and it’s changing how engineers look at aircraft power and design.  Although the aircraft industry continues to adopt innovative technologies, which are making current aircraft more energy efficient, there’s new interest in exploring alternative propulsion systems and energy sources. This new interest presents an opportunity to develop cutting-edge technologies that will dramatically reduce fuel usage, while opening up potential new markets and business opportunities for…

Software vastly improves the ability of ships to reroute through unpredictable weather

The Navy is using new software developed by UConn engineering professor Krishna Pattipati to vastly improve the ability to route ships through unpredictable situations. Credit: University of Connecticut Major research discoveries generate news headlines. But a research undertaking by one University of Connecticut engineering lab seeks to forestall some headlines of a different kind. The loss of life because of weather events, as happened on Oct. 1, 2015 when cargo ship El Faro sank with its 33-member crew in Hurricane…

The First Evidence of Exoplanets — ScienceDaily

Beneath an elegant office building with a Spanish-style red tiled roof in Pasadena, California, three timeworn storerooms safeguard more than a century of astronomy. Down the stairs and to the right is a basement of wonder. There are countless wooden drawers and boxes, stacked floor to ceiling, with telescope plates, sunspot drawings and other records. A faint ammonia-like smell, reminiscent of old film, fills the air. Guarding one storeroom is a short black door with a sign saying “This door…

Gradation-tint smart window

Dimming glass (20 cm x 20 cm) whose darkness can be varied from a completely darkened state (left) to a completely clear state (right). Credit: National Institute for Materials Science (NIMS) NIMS, Waseda University and Tama Art University developed together smart glass capable of producing various shades on its surface. Unlike the conventional types, the newly developed tinting smart glass allows users to easily change the shaded area of a window. For example, a user would be able to change…
