Leading-edge Developments in Tourism Ict and Related Underlying Technologies
The tourism industry uses Internet technologies extensively, despite some significant shortcomings. The shortcomings of the current Internet technologies include information overload, difficulty in information finding and extraction, as well as interpretation of the information between different resources. The semantic web, as the next generation web, uses background knowledge about the meaning...
متن کاملLeading Edge Vortices
Leading-edge vortices that form at offdesign conditions can profoundly influence the aerodynamic characteristics of highly swept slender wings. predict wing geometry effects on the progressive spanwise development of leading-edge vortices is presented. This method, which can account for sweep, camber, twist, airfoil shape, flap deflections, and planform shape, is shown to be a useful tool for a...
متن کاملLife at the Leading Edge
Cell migration requires sustained forward movement of the plasma membrane at the cell's front or "leading edge." To date, researchers have uncovered four distinct ways of extending the membrane at the leading edge. In lamellipodia and filopodia, actin polymerization directly pushes the plasma membrane forward, whereas in invadopodia, actin polymerization couples with the extracellular delivery ...
متن کاملThe Leading-Edge Vortex of Swift Wings
Recent investigations on the aerodynamics of natural fliers have illuminated the significance of the Leading-Edge Vortex (LEV) for lift generation in a variety of flight conditions. A well documented example of an LEV is that generated by aircraft with highly swept, delta shaped wings. While the wing aerodynamics of a manoeuvring aircraft, a bird gliding and a bird in flapping flight vary signi...
متن کاملRealities at the leading edge of research.
When the Wright brothers set out to invent a flying machine at the end of the nineteenth century, they knew they were facing quite a challenge. Not only was it a daunting task to accomplish powered flight but also to overcome the ideology, morality and sensibility of their time, when most people believed that human flight was neither possible nor natural. Science fiction author Arthur C. Clarke...
