The process of developing software systems that meet performance objectives has been called Software Performance Engineering (SPE). The goal of SPE techniques is to construct performance models in each phase of the software development cycle. This allows us to detect designs that are likely to exhibit unacceptable performance. Simple models are preferable in early stages of the development cycl...

In WDM networks, it is important to protect connections against link failures due to the high bandwidth provided by a fiber link. Although many p-cycle based schemes have been proposed for single-link failure protection, protection against two-link failures have not received much attention. In this paper, we propose p-cycle based protection schemes for two-link failures. We formulate an ILP mod...

Topology for reactive power compensation of dynamic load in closed loop is presented. The scheme consists of Thyristor Binary Switched Capacitor (TBSC) banks and a Thyristor Controlled Reactor (TCR). TBSC is based on a chain of Thyristor Switched Capacitor (TSC) banks arranged in binary sequential manner. TCR capacity is chosen to be smallest of TBSC step size. A transient free switching of TBS...

The demand of highly efficient and stable DC to AC inverters used in renewable energy systems to convert DC output from green energy sources into purely sinusoidal unwavering AC is on rise, due to low cost energy generation and conversion, less complexity and environmental factors. Later this converter energy can be feed in to grid or utility supply for load sharing purpose also (can be work as...

Title of Document: A NON-LINEAR DAMAGE MODEL WITH LOAD DEPENDENT EXPONENTS FOR SOLDERS UNDER SEQUENTIAL CYCLIC SHEAR LOADS Elviz George, Ph.D., 2015 Directed By: Professor Michael G. Pecht, Department of Mechanical Engineering The damage state of a material subject to cyclic loads is often characterized by the cycle ratio of applied cycles to the number of survivable cycles. The damage in a mat...

INTRODUCTION There is a suspicion of increased risk of Epstein-Barr virus (EBV)-associated lymphoproliferations in patients with inflammatory arthritides receiving immunosuppressive drugs. We investigated the EBV load and EBV-specific T-cell response in patients treated with methotrexate (MTX) or anti-TNF therapy. METHODS Data for patients with rheumatoid arthritis (RA) (n = 58) or spondylart...

System level virtualization provides several advantages: (i) customization is eased since virtual machines may be based on different systems; (ii) virtual machines are isolated from hardware, subsequently applications are isolated via the virtual machines; (iii) basic fault tolerance mechanisms – pro-active fault tolerance through virtual machine migration and virtual machine snapshot/restore; ...

In asynchronous duty-cycled wireless sensor networks, it is desirable that the data forwarding scheme is adaptive to the dynamics caused by the uncertainty of sensor nodes’ working schedules. Contentionbased forwarding is designed to adapt to the dynamic environments. In this work, we are interested in the contention-based geographic forwarding (CGF) for two asynchronous duty-cycling (ADC) mode...

Energy efficiency is still a challenging issue in wireless sensor networks (WSNs). Balancing nodes’ activities and duty cycling are efficient ways that could enhance WSN’s performances. In this paper the authors introduce a new asynchronous power saving mechanism that provides an adaptive duty cycle and a minimum overhead to achieve load balancing and energy saving. This mechanism relies on two...

The study emphasizes on the use of desiccant air conditioning (DAC) system for the storage of agricultural products. The chilling sensitivity of the tropical fruits and vegetables makes this system more promising for their optimal storage. The desiccant air conditioning system assisted by Maisotsenko cycle evaporative cooler is proposed in the study to achieve the latent and sensible load of ai...
