Abstract We study the motion of test particles and photons in vicinity (2+1)-dimensional Gauss–Bonnet (GB) BTZ black hole. find that presence coupling constant serves as an attractive gravitational charge, shifting innermost stable circular orbits outward with respect to one for this theory four dimensions. Further, we consider lensing, GB gravity (2+1) dimensions show parameter causes bending ...

Manipulating seat configuration (i.e., seat tube angle, seat height and pelvic orientation) alters the bicycle-rider geometry, which influences lower extremity muscle kinematics and ultimately muscle force and power generation during pedaling. Previous studies have sought to identify the optimal configuration, but isolating the effects of specific variables on rider performance from the confoun...

semantic shifting which is one of the most important semantic processes forming the meaning of some linguistic structures was first introduced by safavi (1379). the meaning of different structures such as proverbs, are made by semantic shifting which takes place on the syntagmatic axis, but is shown on the paradigmatic axis. the corpus used in this study consists of 10 persian proverbs which ar...

Interharmonic is an emerging issue in photovoltaic (PV) systems. It has been revealed previous studies that the maximum power point tracking (MPPT) control one potential source for interharmonics. In cascaded H-bridge (CHB) PV inverters, if MPPT perturbations of CHB cells are in-phase, sum voltages all will oscillate with a higher amplitude, leading to amplification interharmonics delivered gri...
