Target track is an important research dot in weapon performance testingfiled, to stable track the flying target in optical detection system and testing instrument, horizontal trajectory tracking system based on rotating mirror was researchedin this paper.A horizontal trajectory tracking method was proposed for the tracking problem in the process of the projectile flight, the design of rotating ...

On the basis of predecessors' research and the existing theory, for convenient and reliable to study the biological effect of low frequency rotating magnetic field, design a high precision and low frequency rotating magnetic field generator, which could be used to stimulate the small area. Choose stepper motor to drive permanent magnet for produce a rotating magnetic field, which can reduce the...

This paper investigates the behavior of rotating binaries. A rotation by r digits to left a binary number B exhibits in particular cases divisibility l∣N1(B)·r+1, where l is bit-length and N1(B) Hamming weight B, that ones B. The integer called left-rotational distance. We investigate connection between this rotational distance, length, numbers. Moreover, we follow question under which circumst...

We present the first post core collapse models of initially rotating star clusters, using the numerical solution of an orbit-averaged 2D Fokker-Planck equation. Based on the code developed by Einsel & Spurzem (1999), we have improved the speed and the stability and included the steady three-body binary heating source. We have confirmed that rotating clusters, whether they are in a tidal field o...

We formulate the Rindler space description of rotating black holes in string theories. We argue that the comoving frame is the natural frame for studying thermodynamics of rotating black holes and statistical analysis of rotating black holes gets simplified in this frame. We also calculate statistical entropies of general class of rotating black holes in heterotic strings on tori by applying D-...

The differential acceleration between a rotating mechanical gyroscope and a non-rotating one is directly measured by using a double free-fall interferometer, and no apparent differential acceleration has been observed at the relative level of 2×10-6. It means that the equivalence principle is still valid for rotating extended bodies, i.e., the spin-gravity interaction between the extended bodie...
