Parallel load balancing is studied for problems with certain bisection properties. A class of problems has bisectors if every problem p of weight w(p) in the class can be subdivided into two subproblems whose weight (load) is at least an -fraction of the original problem. A problem p is to be split into N subproblems such that the maximum weight among them is as close to w(p)=N as possible. It ...

The dynamic response of the railway under accelerated moving load using Dynamic Green Function is presented in this paper. For this purpose, an exact and direct modeling technique is introduced for the railway modeling as the damped Euler-Bernoulli beam on the partial Winkler foundation with arbitrary boundary conditions subjected to the moving load. The effects of the elastic coefficient of Wi...

Transoral robotic surgery (TORS), performed with the da Vinci surgical system (da Vinci), has been classified as a surgical approach for benign and malignant lesions of the oral cavity and laryngopharynx. It provides several unique advantages, which include a three-dimensional magnified view, ability to see and work around curves or angles, and the availability of two or three robotic arms. At ...

From the power systems security point of view, determining voltage stability margin is essential for operation systems. An inaccurate determination maximum loading factor or collapse in a system may cause instability and blackout system. So, applying proper method with high accuracy speed vital analysing This article presents novel based on Thevenin equivalent to accurately determine load-abili...

We investigate randomized processes underlying load balancing based on the multiple-choice paradigm: m balls have to be placed in n bins, and each ball can be placed into one out of 2 randomly selected bins. The aim is to distribute the balls as evenly as possible among the bins. Previously, it was known that a simple process that places the balls one by one in the least loaded bin can achieve ...

As an important part of power system planning and the basis of economic operation of power systems, the main work of power load forecasting is to predict the time distribution and spatial distribution of future power loads. The accuracy of load forecasting will directly influence the reliability of the power system. In this paper, a novel short-term Empirical Mode Decomposition-Grey Relational ...

Numerous wireless sensor network algorithms assume that individual sensors possess location information. However, state of the art localization algorithms often achieve acceptable performance only under restrictive assumptions. For instance, some algorithms necessitate regular sensor deployment or centralized computations. Other algorithms require a high proportion of position aware nodes or th...
