The objective of this project is to investigate an energy efficient air conditioner to be able to compete with conventional vapour compression systems. Liquid desiccant air dehumidifier/indirect evaporative cooling using cross-flow type Plate Heat Exchanger (PHE) as dehumidifier offers a cost effective and more environmentally friendly air conditioning system. It removes moisture form the air a...

Cooling devices and methods are now integrated into most laser systems, with a view to protecting the epidermis, reducing pain and erythema and improving the efficacy of laser. On the basis of method employed, it can be divided into contact cooling and non-contact cooling. With respect to timing of irradiation of laser, the nomenclatures include pre-cooling, parallel cooling and post-cooling. T...

With the right dimensions, a laser composed of series quantum wells emits hard-to-produce terahertz-frequency light without usual need for cryogenic cooling.

Improvements in the efficiency of gas turbine engines over decades have led to increasing inlet temperatures. This, turn, has resulted need cool blades themselves avoid damage them. While air-cooling and film-cooling methods been adopted as primary blade cooling, heat pipe cooling method shows greater potential terms temperature uniformity, maximum allowable temperature, reliability, durability...

We present two nonlinear di usion processes with timedependent di usion coeÆcients. Both processes converge to nontrivial solutions, eliminating the need to impose an arbitrary di usion stopping time, otherwise required in the implementation of most nonlinear diffusion processes. The two schemes employ nonlinear cooling mechanisms that preserve edges. One scheme is intended for general denoisin...

In data grid, using reservation is accepted to provide scheduling and service quality. Users need to have an access to the stored data in geographical environment, which can be solved by using replication, and an action taken to reach certainty. As a result, users are directed toward the nearest version to access information. The most important point is to know in which sites and distributed sy...

An experimental study of hydrodynamics of film cooling is performed by using a single longitudinal slot on a cylindrical model simulated to the leading edge of the gas turbine blade. The model is set up into the test section of an open-circuit induced flow wind tunnel which provides the main flow. The injected air, as a secondary film flow, produced from a high pressure compressor is considered...

This paper explores the statistical features inherent in clinical trials that make it so difficult to come up with the right answers. No matter how skilled and diligent the research team, their trial may still produce the wrong conclusions. Consumers, healthcare professionals as well as the general public should be aware of the liabilities that threaten clinical investigations. In spite of the ...

Mendel’s laws, phenotype and genotype, recessive and dominant. Do these terms sound familiar to you from your biology lessons? This article regarding formal genetics will introduce you to all important genetic fundamentals regarding biology that you need to know as a physician. By studying and revising the contents of this article, you will be in a better position to do well both in your precli...
