The selection of pull strategy or push strategy for specific products depends on not only the change of demand, but also the importance of scale economy for production and distribution. In fact, almost no complete pull strategy or complete push strategy is adopted from begin to end in practice, and in most cases, the combined push-pull strategy is adopted in a marketing process. This paper will...

The focus of this paper is the study of direct alternating-current (ac)–ac converters, beginning by buck, halfbridge, full-bridge, and push–pull converters. From the basic converters, we apply a simple methodology to make the use of switches in commercial configurations possible. Following that, eight voltage restorers supplied either on the line side or on the load side are proposed. A compara...

F or gauging inflationary pressures, many policymakers and financial market analysts pay close attention to the behavior of wages. It is widely believed that if wage costs rise faster than productivity, the price level may rise as firms pass forward increased wage costs in the form of higher product prices. Hence changes in productivity-adjusted wages1 are believed to be a leading indicator of ...

The rapid pace of change in modern medicine makes training on simulation platforms an absolute necessity. With the microprocessors the sophistication of simulators exploded. More recently medicine has developed simulators that are becoming increasingly sophisticated, especially in anesthesia training but also to train intensive care personnel. This is an area that will rapidly advance in the fu...

We present a simple and generic theoretical description of actinbased motility, where polymerization of filaments maintains propulsion. The dynamics is driven by polymerization kinetics at the filaments’ free ends, crosslinking of the actin network, attachment and detachment of filaments to the obstacle interface and entropic forces. We show that spontaneous oscillations in the velocity emerge ...

The most important mission of sociology is perhaps to push forward the production of society. Sociologists should not only in its theory, but also in its practice, help resist the pressure from the state and the market, on the one hand, and assist society to emerge and grow, on the other. In facing the problem of the production of society, sociologists must strive for a transition from a sociol...
