This paper discusses factors that affect the longevity and durability of an induction motor. Various topics include overall construction of an induction machine and its major components, field and operating conditions, motor vibration, operating temperatures, installation practice and proper motor selection for special environment and application conditions. Sound machine design, proper selection...
This paper discusses the difference in performance of an induction motor while tested at manufacturing factory test stand and customer site. The induction motor is the prime mover in any process or chemical or power generating industries. There are several factors affecting the performance of the induction motor. They are type of driven equipment, installed conditions such as ambient temperature,...
Ultrasound has shown a great potential for serving as an outcome measure for localized scleroderma. High spatial resolution of ultrasound will aid to evaluate Echogenicity, Vascularity index and tissue thickness of localized scleroderma. Echogenicity is higher when the ultrasound waves reflected are lesser in value from any particular body organ. Vascularity index can be defined as the differences...
Digital watermarking is the technique used to embed author's credentials, logo or some other information into digital images which can be used in authentications for courtroom evidence, copyright claims and other applications. The objective of this work is to develop a feasible and invisible watermark embedding hardware for the secure digital cameras using LeGall 5/3 (Discrete Wavelet Transform) DWT...

4 ?? 4 ring array antennas are combined with commercially available and custom designed RF components to realize a base station operating for channel #1 of UWB communications. The 4 transmitters and receivers modules are developed using LNA, PA, buffer amplifiers, custom designed single and dual GCM mixers, and differential BPF and LPF. The GCM mixer is driven by a StLO poly-phase board that is realized...
