An Arrayed Wireless Sensor Network (AWSN) comprises of a large number of small self-contained packages (nodes) that contain a bank of various environmental sensors, a power and a communications module equipped with a microstrip antenna array and an array processor. Although nodes have fixed positions, they may group together under specific rules to form dynamic entities, called wireless arrays,...
Investigating Effective Parameters in Tactile Determination of Artery included in Soft Tissue by FEM
One of the newest ways of surgery is known as Minimally Invasive Surgery (MIS), which in spite of its benefits, because of surgeon's tactile sensing omission, causes some problems with detection of arteries and their exact positions in tissue during a surgery. In this study, tactile detection of an artery in tissue has been modeled by finite element method. In this modeling, three 2D models of ...
Digital's AlphaServer multiprocessor systems are high-performance servers that combine multiprocessing technology with PC-style I/O subsystems. The system architecture allows four processing nodes, four memory nodes (up to a maximum of 2 GB), and two I/O nodes. All nodes communicate through a system bus. The system bus was designed to support multiple generations of Alpha processor technology. ...
Approximately, twenty years ago, the Rare Cancer Network (RCN) was formed in Lausanne, Switzerland, to support the study of rare malignancies. The RCN has grown over the years and now includes 130 investigators from twenty-four nations on six continents. The network held its first international symposium in Nice, France, on March 21-22, 2014. The proceedings of that meeting are presented in two...
A set of five free software solutions for generating realistic human head models from subject-specific MRI data are compared. Boundary Element Method (BEM) is used for realistic modelling. Software tools that can perform the MRI segmentation and can generate BEM surfaces or meshes for those segments are selected for comparison. Performances of those software tools are analysed and compared base...
growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
Linking architectural models to structural analyses can be demanding and time-consuming, especially when the cannot accurately analysed using readily available one- or two-dimensional finite elements. This paper presents a tool for element analysis solid elements developed as plugin Grasshopper 3D® that enables designers include of complex objects within same software design exploration. A benc...
Effective fault classification of rolling element bearings provides an important basis for ensuring safe operation of rotating machinery. In this paper, a novel vibration sensor-based fault diagnosis method using an Ellipsoid-ARTMAP network (EAM) and a differential evolution (DE) algorithm is proposed. The original features are firstly extracted from vibration signals based on wavelet packet de...
