A key concept in research on the media coverage of politics is the game or strategy frame. Contrasted with coverage of politics as issues, the framing of politics as a strategic game is marked by features such as winning and losing as the central concern and a focus on how candidates or parties are doing in opinion polls. The pervasiveness of such framing is, however, disputed since (1) the way...

In order to solve the problem that three-phase current of interior permanent magnet synchronous motor (IPMSM) contains 11th and 13th harmonics, a multiple rotating frame transformation (MSRFT)-based harmonic suppression method is established. Firstly, influencing factors harmonics in IPMSM vector control are analyzed, influence mechanism inverter’s dead-time effect flux linkage on described. Se...

Pulsewidth modulated (PWM) current-source rectifiers (CSR), among other alternatives, offer marked improvements over thyristor line-commutated rectifiers as a source of variable dc power. Advantages include reduced line current harmonic distortion and complete displacement power factor control, including unity displacement power factor operation. However, due to nonlinearities of the PWM-CSR mo...

In this paper we present an original motion compensation strategy based on frame partitioning. The proposed method uses different temporal resolutions within a frame to improve compression. We present a new bit allocation and rate control algorithm complementing our motion compensation technique. This unique approach to bit allocation ensures the consistency of quality throughout a single frame...

Structural walls commonly used as efficient structural elements to resist lateral and vertical loads. Diverse performance of bearing wall system in past earthquakes, motivates investigation on the adequacy of current seismic design provision for these walls. This study considers seismic performance of model walls of bearing wall and building frame systems designed as ordinary and special struct...
