High-Tech Robotic Fish Glides Through Water With Great Ease
2013-01-17 12:54:52

Lee Rannals for redOrbit.com — Your Universe Online Scientists from the Michigan State University made a number of improvements on a high-tech robotic fish. The new fish, called Grace, was designed and built by Xiaobo Tan, an MSU associate professor of electrical and computer engineering, and his team. They equipped the new fish with an array of sensors, allowing it to travel autonomously through the water, as well as measure water temperature, quality and other pacts. These...

Commercial Customers save thousands monthly on water utility bills with a new water Conservation Valve. This patented Turbulence Reduction System uses a reverse flow pulse to reduce the meter spin by compressing any air that is entrapped in the municipal water system. Southampton PA (PRWEB) December 26, 2012 Commercial Customers save 5 to 12% on water utility bills with a new Conservation Water Valve. A Pennsylvania energy consulting company is helping large water users nationwide reduce...

Grains Cause Meteorite Impact Waves To Spread Unevenly
2012-12-12 13:06:31

April Flowers for redOrbit.com - Your Universe Online Scientists at Duke University have gained a new microscopic picture of the way the energy of a meteorite or a missile transfers to sand and dirt grains by observing high-speed video of projectiles slamming into a bed of disks. The study, published in Physical Review Letters, showed that the transfer is jerky, not smooth as the researchers believed it would be. "It was surprising just how un-smooth the slow-down of the intruding...

Sneaky Owls Use Stealth And Fly Silently
2012-11-20 15:58:27

Alan McStravick for redOrbit.com — Your Universe Online Researchers are learning about stealth technology from a famous winged inhabitant in nature. Would you like to know just who-who they are taking their lead from? If you guessed the owl, well the “who” clue wasn´t exactly the most difficult. The reason they are looking at the owl is for its ability to fly silently. It is able to do this because of the natural design of its plumage, which aids in noise...

Navy Looks To Rotating Detonation Engines To Improve Fuel Consumption
2012-11-02 12:49:58

U.S. Naval Research Laboratory With its strong dependence on gas-turbine engines for propulsion, the U.S. Navy is always looking for ways to improve the fuel consumption of these engines. At the Naval Research Laboratory (NRL), scientists are studying the complex physics of Rotating Detonation Engines (RDEs) which offer the potential for high dollar savings by way of reduced fuel consumption in gas-turbine engines, explains Dr. Kazhikathra Kailasanath, who heads NRL's Laboratories for...

The boomerang is a flying tool, made of wood or carbon fiber-reinforced plastic, with a curved shape that is often used as a weapon or for sport. They have also been made of bones and come in many different shapes and sizes depending on their geographic or tribal origins and their intended function. The most commonly recognizable type is the returning boomerang which travels in an elliptical path and returns to its point of origin. The returning boomerang has lopsided wings in order to create...

A Vortex (plural: vortices) is a spinning, often turbulent, mass of flowing fluid. Any spiral movement with a closed streamline is considered vortex flow. The speed and rate of rotation of a vortex is always greatest at the center, with progressively decreasing speed away from the center. The fluid pressure is lowest in the center of the vortex, and rises further from the center (Bernoulli's Principle). The core of a vortex is sometimes visible due to a plume of water vapor caused by...

Turbulence (or turbulent flow) is characterized by chaotic, random property changes. Turbulence occurs with low momentum diffusion (spreading of atmospheric properties), high momentum convection (vertical transference of atmospheric properties), and rapid variation of pressure and velocity in both space and time. A flow that is not turbulent is known as laminar flow. A vortex moving at low speeds will most likely cause laminar flow, and as speeds increase a transition is made to turbulent...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
