Abstract Breadth-first and depth-first search are basic search strategies upon which many other search algorithms are built. In this paper, we describe an approach to integrating these two strategies in a single algorithm that combi ....etc

A special type of brushless motor is called a limited-angle torquer (LAT). LATs are constrained to produce torque through a rotation angle of less than 180 degree, But they are widely used to operate servovalves, direct laser mirrors, position missile-guidance radar antennas, open shutters for heat-seeking sensors, and power other systems that rotate through small angles.

The rotor in a limited-angle torquer carries field magnets, and the stator supports armature windings (similar to the construction of conventional brushless motors). LATs, ....etc

Wide angle X-ray scattering (WAXS) is an X-ray diffraction technique that is often used to determine the crystalline structure of polymers. This technique refers to the analysis of Bragg Peaks scattered to wide angles, implies that they are caused by sub-nanometer sized structures.Wide angle x-ray scattering is the same technique as Small-Angle X-ray Scattering (SAXS) with the distance from sample to the detector is shorter and thus diffraction maxima at larger angles are observed.The technique is a time-honored but a somewhat out-of-favor tec ....etc
