Leakage power accounts for an increasingly larger portion of total power consumption in deep submicron technologies. Active leakage control method reduces leakage power by dynamically disconnecting supply to inactive blocks and adjusting body bias to further limit leakage and maintain performance. The active leakage control scheme is advantageous for blocks with low activity factors and relativ...

When a natural gas pipeline ruptures, the adjacent automatic line control valves (ALCVs) should close quickly to prevent leakage or explosion. The differential pressure set point (DPS) at each valve location is the main criteria for value setting in ALCV action. If the DPS is not properly adjusted, the ALCV may mistakenly close or it may not take any action at proper time. This study focused on...

A multi-class single-server system with general service time distributions is studied in a moderate deviation heavy traffic regime. In the scaling limit, an optimal control problem associated with the model is shown to be governed by a differential game that can be explicitly solved. While the characterization of the limit by a differential game is akin to results at the large deviation scale, ...

This section is written to introduce the reader to nonlinearity and its effect in control systems, and also to ‘set the stage’ for the subsequent articles. Nonlinearity is first defined and then some of the physical effects which cause nonlinear behavior are discussed. This is followed by some comments on the stability of nonlinear systems, the existence of limit cycles, and the unique behavior...

We optimize a selection of eigenvalues the Laplace operator with Dirichlet or Neumann boundary conditions by adjusting shape domain on which eigenvalue problem is considered. Here, phase-field function used to represent shapes over we minimize. The idea behind this method modify introducing dependent coefficients in order extend fixed design containing all admissible shapes. resulting and topol...
