CDMA
The world is demanding more from wireless communication technologies than ever before as more people around the world are subscribing to wireless. Add in exciting Third-Generation (3G) wireless data services and applications - such as wireless email, web, digital picture taking/sending, assisted-GPS position location applications, video and audio streaming and TV broadcasting - and wireless networks are doing much more than just a few years ago.
This is where CDMA technology fits in. CDMA consistently provides better capacity for voice and ....etc

SPECT

ABSTRACT

SPECT, the acronym for Single Photon Emission Computed Tomography, is a nuclear medicine imaging modality, giving information about a patient s specific organ or body system. SPECT is a nuclear medicine technique that uses radiopharmaceuticals, a rotating camera and a computer to produce images which allow us to visualize functional information about a patient s specific organ or body system. SPECT images are functional in nature rather than being purely anatomical such as ultrasound, CT and ....etc

Detecting Patient Motion in SPECT Imaging Using Stereo Optical Cameras



1. Introduction
Patient motion causes many problems in SPECT imaging, such as blur and other motion artifacts. If patient motion is excessive, it may be necessary to repeat an acquisition, with consequent cost and inconvenience. Previous approaches to motion detection relied on inconsistency checks or motion tracking, or were limited to rigid body parts, such as the head. The goal of this work is to design a more general sys ....etc

SPECT is used to make three dimensional images of the heart, to perform brain studies and for skeletal scintigraphy. It is reasonable to speculate about a constant by perhaps a slower rate of increase of clinical applications of SPECT. It is safe to conclude that SPECT has reached the stage where it will be a valuable and also an unavoidable asset to the medical world. SPECT is used routinely to help diagnose and stage cancer, stroke, liver disease, lungs disease and a host of other physiological (functional) abnormalities. ....etc

Definition

With the proliferation of portable electronic devices, power efficient data transmission has become increasingly important. For serial data transfer, universal asynchronous receiver / transmitter (UART) circuits are often implemented because of their inherent design simplicity and application specific versatility. Components such as laptop keyboards, palm pilot organizers and modems are few examples of devices that employ UART circuits. In this work, design and analysis of a robust UART architecture has been carried out to minimiz ....etc

There are currently many research groups active in the field of photovoltaics in universities and research institutions around the world. This research can be categorized into three areas: making current technology solar cells cheaper and/or more efficient to effectively compete with other energy sources; developing new technologies based on new solar cell architectural designs; and developing new materials to serve as more efficient energy converters from light energy into electric current or light absorbers and charge carriers.

One way of ....etc

ABSTRACT
SPECT, the acronym for Single Photon Emission Computed
Tomography, is a nuclear medicine imaging modality, giving information
about a patient s specific organ or body system. The patient is
injected with a radiopharmaceutical, which will emit Gamma rays. The
radio activity is collected by an instrument called gamma camera and
the image is reconstructed. SPECT is used to make three dimensional
images of the heart, to perform brain studies and for skeletal
