The estimation of thermodynamic behavior during filling processes with entrapped air in water pipelines is a complex task as it requires solving system algebraic-differential equations. A lot different numerical methods have been used for this purpose literature including the rigid column (RWC) model. main advantage RWC model its acceptable accuracy very low computational load. In that context,...

Background: Out-of-pocket and informal payments are considered as 2 most important topics for equity in health care financing. Therfore, this study was conducted to systematically review and meta-analyze the status of these payments in Iran's health care system.    Methods: Required data were collected through searching the following key terms: "Unofficial", "Informal ...

pocket infection of a cardiac device is usually treated by removing the device and re - implanting it in a new site after complete treatment of the infection. this report illustrates a complicated case of pocket infection in the wake of the implantation of a permanent pacemaker (cardiac resynchronization therapy). the patient was treated conservatively through daily irrigation and dressing, bro...

In this note we consider two different singular limits to hyperbolic system of conservation laws, namely the standard backward schemes for non linear semigroups and the semidiscrete scheme. Under the assumption that the rarefaction curve of the corresponding hyperbolic system are straight lines, we prove the stability of the solution and the convergence to the perturbed system to the unique sol...

Small devices such as Palm and Pocket PC have gained much popularity with the advent of mobile technology and price affordability. Image browsers are among popular software applications on PDAs. The limitations introduced by these devices such as screen resolution, processing power and interaction make it harder for multimedia applications designed for larger displays to be as much usable on sm...

This paper present numerical computations of solitary wave impact on a vertical wall. Different breaking cases were studied such as the high-aerated (air-pocket) or low-aerated (flip-through) in order to test software ability accurately reproduce generated wall pressure loads. The toolbox OpenFOAM was used here under incompressible and compressible assumptions, together with 2D 3D configuration...

The Itsy pocket computer is a flexible research platform developed at Compaq Computer Corporation’s Western Research Laboratory (WRL). The goal of this project is to enable hardware and software research in handheld computing. Several versions of the Itsy system were designed and built. This document evaluates the power consumption of Itsy version 2.4. A similar study was performed for Itsy v2....

Several previous studies have been performed which evaluate the power consumption of the Itsy pocket computer version 2, developed at Compaq Computer Corporation’s Western Research Laboratory (WRL). Attempts have been made by others to use the data from these studies to characterize the behavior of the Lithium-ion battery used for the Itsy. Although our previous studies correctly characterize t...
