Many conceptual designs for advanced short-takeoff, vertical landing (ASTOVL) aircraft need exhaust nozzles that can vector the jet to provide forces and moments for controlling the aircraft's movement or attitude in flight near the ground. A type of nozzle that can both vector the jet and va...

This chapter discusses the numerical characteristics of random variables. For a rough characteristic of a scalar random variable, one may restrict oneself to its mean value and some number characterizing the scatter of its possible values. For an indefinitely increasing number of trials n, the freque...
But for an efficient team, the role of its members is flexible and variable, and it is constantly being adjusted. This requires members to have adequate negotiating skills. Because the problems and relationships in the team change frequently, members must be able to face and cope with the ...
English language, a West Germanic language of the Indo-European language family that is closely related to the Frisian, German, and Dutch languages. It originated in England and is the dominant language of the U.S., the U.K., Canada, Australia, Ireland,
Recently, a new type of low-loss variable inlet guide vane (VIGV) was proposed for improving a compressor’s performance under off-design conditions. To provide more information for applications, this work investigated the effect of the Reynolds number and clearance flow on the aerodynamic charact...
Initially, the idea of natural ventilation was introduced using a four-sided windcatcher model for a building. Then, this idea was applied for a one-sided windcatcher to analyze the effect of using an internal section inside the windcatcher tower. Moreover, variable cross-section areas of the...
of algae, some calcareous, which help to build the reefs.The size of reefs is variable.Some atolls are very large—Kwajelein in the Marshall Islands of the South Pacific is 120 kilometers long and as much as 24 kilometers across-but most are very much smaller, and rise only a few ...
This paper presents analytical methods to predict the magnetic field distribution, electrical parameters, and output characteristics of a high speed synchronous generator equipped with surface-mounted permanent magnet. In order to analyze the magnetic field distribution and to estimate the electrical paramete...
The maximum ECA changes in the North Pacific and the North Atlantic, which are the largest variations in the Northern Hemisphere, are independent of each other, and their mechanisms may be different. Furthermore, MSLP is a significant physical variable that affects ECA. The North Atlantic ...
