Obsolete hardware can be effectively reused through intelligent software optimization, which is possible only when source code is available. Virtual Distro Dispatcher (VDD) is a system that produces virtual machines on a central server and projects them on a number of costless physical terminals. VDD is the result of an extreme software optimisation based on virtualization and terminal servers....

A four-bit adder is simulated using HSPICE in two classic design methods: a ripple-carry adder (RCA) and a carry-look-ahead adder (CLA). All components of the adders are composed of PMOS, NMOS, and capacitors. The propagation delay and power dissipation were measured under different VDD values and different operating temperatures in HSPICE. A comparison of these two metrics were analyzed betwee...

Vertical integration is often proposed as a way to resolve hold-up problems, ignoring the empirical fact that division managers tend to maximize divisional (not firmwide) profit when investing. This paper develops a model with asymmetric information at the bargaining stage and investment returns taking the form of cash and “empire benefits.” Owners of a vertically integrated firm then will prov...

The Distributed object migration environment (Dome) addresses three major issues of distributed parallel programming: ease of use, load balancing, and fault tolerance. Dome provides process control, data distribution, communication, and synchronization for Dome programs running in a heterogeneous distributed computing environment. The parallel programmer writes a C++ program using Dome objects ...

Recent studies report a high prevalence of vitamin D deficiency (VDD) among patients with sickle cell disease (SCD), with rates as high as 65–100% depending on the season (Buison et al, 2004; Lal et al, 2006; Adewoye et al, 2008; Rovner et al, 2008; Chapelon et al, 2009). Despite this evidence, VDD remains both under-recognized and under-treated in patients with SCD. There appears to be substan...

In this paper, we propose a technique for designing low-power fast Fourier transform (FFT) processors with applications in next generation wireless LAN and wireless access systems. The proposed low-power technique is based on the general principle of soft digital signalprocessing [4] where voltage overscaling (VOS) [4] (scaling the supply voltage beyond the critical voltage vdd-crit required fo...

INTRODUCTION AND OBJECTIVES Single-lead VDD pacing provides the physiological benefits of atrioventricular synchrony with the convenience of a single-lead system. However, concern remains about the method's safety and effectiveness. METHOD In total, 700 patients with single-lead VDD pacemakers were evaluated retrospectively. The following parameters were recorded: age, sex, etiology, the symp...

Background: Vitamin D deficiency (VDD) in pregnancy has been found to be associated with adverse outcome various observational studies. Evidence from randomized control trials is necessary change current recommendations. Aims and Objectives: We conducted controlled trial assess the effect of supplementation on outcome. also looked for predictors VDD as universal testing neither recommended nor ...

<b>Background: </b>Vitamin D deficiency (VDD) is the one of major public health problem affecting approximately billion people all over world. In recent years, relationship allergic diseases with a low concentration vitamin has been studied worldwide. An association found between small count serum and development immune disorders. Patients disorders and, in particular, respiratory a...
