Study Of Partial Discharge Activity In Magnet Wires Aged By Combined Stresses, Ashwini Mani Dec 2005

Study Of Partial Discharge Activity In Magnet Wires Aged By Combined Stresses, Ashwini Mani

Theses and Dissertations

Partial discharge testing is a nondestructive method of identifying possible premature insulation breakdown. Magnet wires are used in various electrical equipment like injection coils, solenoids, small transformers and motors. Winding wires used in high voltage systems are subjected to several stresses during operation, which considerably lowers their lifetime. A prolonged combined effect of these stresses causes aging of the wires, inception of partial discharge activity, and degradation of the organic material in the enamel coating and varnish used by the manufacturer. The tests were conducted for AWG 30 and AWG 31 twisted magnet wire samples. The samples are aged under …

Parallel Compositing Of Multi-Temporal Satellite Imagery Using Temporal Map Algebra, Bijay Shrestha Dec 2005

Parallel Compositing Of Multi-Temporal Satellite Imagery Using Temporal Map Algebra, Bijay Shrestha

Theses and Dissertations

Spatio-temporal satellite image analysis is a technique for monitoring spatial and temporal changes of land cover and oceanic locations on earth. Temporal Map Algebra (TMA) is a novel technique developed by Jeremy Mennis and Roland Viger for analyzing a time series of satellite imagery using simple algebraic operators that treats time series of imagery as a threedimensional data set, where two dimensions encode planimetric position on earth surface and the third dimension encodes time. The high dimensionality of raster data leads to high computational cost, which is why parallel computation is attractive. This thesis describes the design, implementation, andmperformance evaluation …

Critical Properties Of Small World Ising Models, Xingjun Zhang Dec 2005

Critical Properties Of Small World Ising Models, Xingjun Zhang

Theses and Dissertations

In this dissertation, the critical scaling behavior of magnetic Ising models with long range interactions is studied. These long range interactions, when imposed in addition to interactions on a regular lattice, lead to small-world graphs. By using large-scale Monte Carlo simulations, together with finite-size scaling, the critical behavior of a number of different models is obtained. The Ising models studied in this dissertation include the z-model introduced by Scalettar, standard small-world bonds superimposed on a square lattice, and physical small-world bonds superimposed on a square lattice. From the scaling results of the Binder 4th order cumulant, the order parameter, and …

Development Of An Improved On-Line Voltage Stability Index Using Synchronized Phasor Measurement, Yanfeng Gong

Theses and Dissertations

Recent events, such as the Northeast Blackout of 2003, have highlighted the need for accurate real-time stability assessment techniques to detect when an electric power system is on the brink of voltage collapse. While many techniques exist, most techniques are computationally demanding and cannot be used in an on-line application. A voltage stability index (VSI) can be designed to estimate the distance of the current operating point to the voltage marginally stable point during the system operation. In this research work, a new VSI was developed that not only can detect the system voltage marginally stable point but also is …

Development Of Conjugate Heat Transfer Capability To An Unstructured Flow Solver - U2ncle, Qingluan Xue Dec 2005

Development Of Conjugate Heat Transfer Capability To An Unstructured Flow Solver - U2ncle, Qingluan Xue

Theses and Dissertations

A precise prediction of the heat loads in metal materials in contact with the hot gas is an increasingly demanding problem in the design phase of the complex cooling schemes in the modern turbine engines. The coupled calculation of the fluid flow and the heat transfer is a promising approach as heat transfer coefficients are not necessary in the calculation and the heat transfer itself is part of the calculation and can be derived from local heat fluxes. Therefore, it is useful to incorporate an appropriate scheme for directly coupled heat transfer computations (conjugate heat transfer), capable of handling complex …
