this paper addresses the signal processing principles in passive bistatic radar (pbr) systems. in this case, the detection problem in the presence of system noise, clutter/multipath, direct signal and interfering target signals is investigated. to this light, two types of detectors are studied. in the first one, which is based on intuitive sense, we examine two detectors. in the second type det...

Artificial neural network (ANN) has application in communication engineering in diverse areas such as channel equalization, channel modeling, error control code because of its capability of nonlinear processing, adaptability, and parallel processing. On the other hand, wavelet transform (WT) with both the time and the frequency resolution provides the exact representation of signal in both doma...

This paper present a study of signal processing in Blind Source Separation (BSS) application for medical field, especially during medical data recording. There are two main techniques that will be investigated; Natural Gradient Method (NGM) and Self-Organized Neural Network (SONN). The main source signals are Electrocardiograph (ECG), and Electroencephalograph (EEG) that linearly mixed with noi...

The algorithmic design processes for 3 generic tasks in medical image processing, illustrated on specific applications, are described: (1) registration for intra-oral images, (2) compression for 3D images, (3) segmentation and labelling for images of the cortex.

recently, as the result of the development in modern imaging, computerized three dimensional data processing and advanced engineering techniques, an prosthesis that match the skeletal anatomy can be accurately designed from computer aided design (cad) technique and the physical model of prosthesis or skull replica can be produced through rapid prototyping (rp), rapid tooling (rt), and computer ...
