Maximum power consumption is an important consideration in server design, as the total power envelope affects cooling costs and can limit performance. One approach to limiting total power is power shifting, managing power budgets among system sub-components to meet an overall total constraint. In this paper, we investigate processor-memory power shifting on a multi-threaded, 32-core commercial ...

Multicarrier modulation is a powerful transmission technique that provides improved performance in various communication fields. A fundamental topic of multicarrier communication systems is the bit and power loading, which is addressed in this article as a constrained multivariable nonlinear optimization problem. In particular, we present the main classes of loading problems, namely, rate maxim...

The capacity of the point-to-point vector Gaussian channel under the peak power constraint is not known in general. This paper considers a simpler scenario in which the input signal vector is forced to have a constant envelope (or norm). The capacity-achieving distribution for the non-identity 2× 2 MIMO channel when the input vector lies on a circle in R is obtained and is shown to have a finit...

Catalytic partial oxidation (CPOX) has recently received particular attention because it is one of the most attractive technologies for the production of syngas and hydrogen in small to medium scales. Current study subjected to partial oxidation reforming which have simultaneously studied the effect of the fuel composition and flow rates of methane-oxygen mixed gas on the SOFCs performances. In...

Wind power generation reduces our reliance on fossil fuels and can thus reduce environmental pollution. However, rapid wind power development has caused various issues related to power grid restructuring. A high proportion of the generating capacity of northeast China is based on combined heat and power (CHP), whose inflexible response to the peak regulation of power grids hinders the ability t...

Gate and yard congestion is a typical type of container port congestion, which prevents trucks from traveling freely has become the bottleneck that constrains productivity. In addition, urban traffic increases uncertainty truck arrival time additional costs. More more terminals are adopting appointment system (TAS), tries to manage arrivals evenly all day long. Extending existing research, this...
