Directly learning the swimming behaviors of real fish can significantly enhance the swimming performance of bionic robotic fish. This paper presents a novel transfer learning method based on a dynamic ...

The recent development of various methods of modulation such as PCM and PPM which exchange bandwidth for signal-to-noise ratio has intensified the interest in a general theory of communication. A ...

Time delay and Doppler shift between the echo signal and the reference signal are two most commonly used measurements in target localization for the passive radar. Doppler rate, which can be obtained ...

Metal halide perovskite solar cell (PSC) has successfully distinguished itself in optoelectronic field by virtue of the sharp rise in power conversion efficiency over the past decade. The remarkable ...

Holograms synthesized by computer are used for constructing optical wavefronts from numerically specified objects. Elimination of the need for a physical object has made new applications possible, for ...

The electron plasma frequency reduction factor has proved to be a fundamental design parameter in all types of microwave tubes employing long electron beams. This factor is here calculated for a ...

A major engineering challenge in construction projects lies in the stability as-sessment of rocky slopes with faults. The left bank slope of the Jinchuan Hy-dropower Station in the outlet field is ...

A helical coil radiates a wave of circular polarization in a doughnut pattern if the area and pitch of the turns are properly related to the radianlength of the wave. For a coil whose dimensions are ...

A particle swarm optimization algorithm to search for an optimal five-stage constant-current charge pattern is proposed. The goal is to maximize the objective function for the proposed charge pattern ...

This paper presents a dynamic model of a planar flexible inverted pendulum system under the frame of multi-body dynamics by floating frame of reference formulation (FFRF). By proper simplification and ...

The attenuation and scattering of laser beams by rain, fog, and snow have been calculated and measured at 0.63, 3.5, and 10.6μ. Attenuation of the infrared wavelengths by light fog is up to one order ...
