Coordinated optimal dispatch is of utmost importance for the efficient and secure operation hierarchically structured power systems. Conventional coordinated optimization methods, such as Lagrangian relaxation Benders decomposition, require iterative information exchange among subsystems. Iterative coordination methods have drawbacks including slow convergence, risk oscillation divergence, inca...

In the circuit theory, Norton and Thevenin equivalent generators are tools that simplify solutions of networks involving passive or active components. They have been extensively used in frequency domain to describe time-harmonic sources. A time-stepped evolution is instead typically include transient As a particular case latter, extended here investigate pulsed photoconducting sources, where dc...

In this study, efficient methods for optimal sensor placement (OSP) based on a new geometrical viewpoint for damage detection in structures is presented. The purpose is to minimize the effects of noise on the damage detection process. In the geometrical viewpoint, a sensor location is equivalent to projecting the elliptical noise on to a face of response space which is corresponding to the sens...

Locking caches are a useful alternative to standard cache memories in order to reach both predictability and high performance for multitasking, preemptive, fixedpriority real-time systems. Two schemes of locking cache are possible: static and dynamic use. Both schemas present a high degree of predictability and like-cache performance. But these two schemes are not equivalent. Each one performs ...

In this study, the influence of type and structure of different roofing systems were investigated using computational fluid dynamic method. The considered roofing systems include beam and block types (clay brick, light weight concrete block, polystyrene) and Uboot slab which were designed for 6m and 8m span. To simulate the fluid flow and heat transfer, the computational fluid dynamic method wa...

Abstract Aiming at the fatigue life of bearing in oscillatory applications, through analysis equivalent load each part is calculated. Taking 7005 angular contact ball as research object, stress changes component are obtained transient dynamic model, analyzed based on damage theory, and obtained. The results show that rolling element bearings weak failure under given working condition, it more r...
