Segmentation accuracy determines the success or failure of computerized analysis procedure in biomedical applications. This paper aims to develop a unique segmentation technique to identify mitotic nuclei from microscopy images of breast histopathology slides. The process involves detection and classification of cell nuclei based on computed features. The(More)
—This paper presents the design and analysis of a novel machine family—the enclosed-rotor Halbach-array permanent-magnet brushless dc motors for spacecraft applications. The initial design, selection of major parameters, and air-gap magnetic flux density are estimated using the analytical model of the machine. The proportion of the Halbach array in the(More)
This paper analyses the various losses due to partial shading on different photovoltaic array configurations under moving non-uniform illumination conditions (passing cloud). Each solar array is composed of modules which are interconnected in series and parallel. Bypass diodes are also modelled to avoid hotspot conditions in a photovoltaic module. The(More)
The advent of inexpensive power semiconductors and digital control platforms has generated an interest in machines like switched reluctance motor (SRM) which is known for its structural simplicity. In domestic sector, however, conventional type of single phase induction motor (SPIM) is still commonly used. Most domestic appliances use fractional kilowatt(More)
Wireless power transfer systems are in vogue today and are being widely used in divergent fields like mobile charging systems, medical implants and powering utility devices in smart homes. Magnetic resonance technology between source and load resonators has been demonstrated as a potential means of non-radiative power transfer. In this paper, the basic(More)
Wireless power transfer for lighting gadgets on a table top using low Q resonant coupling is realized. Using distributed capacitances across the transmitter and receiving coils and the inherent resistances of the wires, the coil acts as a tuned LC circuit. Since the secondary coil is resonant with the primary coil at a common frequency of 400 KHz, power is(More)
The exact measure of mitotic nuclei is a crucial parameter in breast cancer grading and prognosis. This can be achieved by improving the mitotic detection accuracy by careful design of segmentation and classification techniques. In this paper, segmentation of nuclei from breast histopathology images are carried out by Localized Active Contour Model (LACM)(More)
Wireless power transfer systems are widely in use today for eliminating the power cord of battery operated devices. The evanescent resonant coupling operating power transfer efficiency between the transmitter and receiver coils is analytically derived. The power transfer efficiency of the wireless power transfer system is analytically determined. The power(More)
When a distributed generator (DG) is connected to a system and if a fault occurs, it acts as a source of fault current. Original relay protection scheme is affected by the connection of distributed generators (DG) and causes mal-operation of both primary and backup relays. The fault current contribution of DG can be limited by placing fault current limiter(More)
