Java bytecode subroutines are used to compile the Java source language try-finally construct into a succinct combination of special-purpose instructions. However, the space saved by using subroutines, in comparison to simpler compilation strategies, comes at a substantial cost to the complexity of the bytecode veriier and other parts of the Java Virtual Machine. This paper examines the trade-oo...

Semiconducting-only single-walled carbon nanotube (SWNT) network field effect transistors (FETs) have been fabricated by selectively reacting all the metallic SWNTs in the devices with diazonium reagents in a controlled manner. We have shown that the concentration of diazonium reagents used is crucial for selectively eliminating metallic SWNTs and keeping semiconducting ones intact. Excessive a...

Recently, BLDC motors have become very popular in wide application areas. The BLDC motor does not have a mechanical commutation, and is, consequently, more reliable than the classic DC motor. In recent years, with the increasing number of nonlinear loads drawing nonsinusoidal current, power quality has become a serious problem; hence an optimal control scheme must ensure the desired motor behav...

Systems of Prony type appear in various signal reconstruction problems such as finite rate of innovation, superresolution and Fourier inversion of piecewise smooth functions. We propose a novel approach for solving Prony-type systems, which requires sampling the signal at arithmetic progressions. By keeping the number of equations small and fixed, we demonstrate that such “decimation” can lead ...

The Governmental Accounting Standards Board Statement 45 (GASB 45) obliges public employers to disclose liabilities related to postretirement medical benefits. Most state and local government entities are beginning to analyze and quantify how GASB 45 liabilities will affect their balance sheets and credit ratings. This article describes the many ways to reduce those liabilities without eliminat...

Bubbles and the dissolved gases in liquids greatly influence the performance of fluid power systems, coating solutions, plants in the food industry and so on. Therefore, it is important to eliminate bubbles in liquids and to prevent degradation of the quality the system performance as well as to avoid possible damage of the components. These problems are often viewed with the knowledge of the d...

The high cost of context switching is one reason that operating system performance is not keeping pace with hardware improvements. Besides the cost of saving and restoring registers, another component of context switch cost is the cache interference between multiple processes sharing the same cache. We measured kernel on user, user on kernel, and user on user cache interference from context swi...
