background: the adverse effects of noise are well known and noise problems due to industrialization of communities are increasing over the time. oil industries due to the process and nature of production; contain many noise sources such as compressors, turbines, and pumps, which cause excessive noise exposure. the objective of this study was to evaluate the noise characteristics of compressors ...

An innovative holographic memory system has been developed at JPL for high-density and high-speed data storage in a space environment. This system utilizes a newly developed electro-optic (E-O) beam steering technology to achieve a design goal of up to 250 Gb storage in a cubic photorefractive crystal with up to 1 Gb/sec transfer rate. Recently, a compact CD-sized holographic memory breadboard ...

Background Wall thickening is the dominant factor for the effective ejection of the left ventricle (LV). Circular tagging is the suitable pattern for studying the radial strain which quantifies the wall thickening. High density tagging facilitates the post processing required for this quantification [1]. Following the recent sequence development for circular tagging, in this work we propose a k...

Introduction: Recent industrial developments in human societies have caused rapid advancements in technologies of production and distribution of electricity, which in turn result in enhancement of power networks and utilization of high voltages. These networks and the high voltages in transfer lines cause the exposure to electric and magnetic fields. In this study, the situation regarding the m...
