that a shockload of 45 kW should be allowed. The desien of The development of a simple chopper harvester is described and ways in which this complicated machine might be simplified are suggested. The decisions taken and some of the specially designed components used in 'building the machine are described and the difficulties experienced during its operation and their solution are explained.

Applications of MEMS variable capacitive sensors are introduced. The design trade-offs of variable capacitive sense amplifiers are discussed and a chopper stabilized variable capacitive sense amplifier topology is introduced. The chopper stabilized topology has the advantage of not being sensitive to 1/f noise, charge injection noise, kT/C noise, and dc offsets. This circuit was designed to mee...

At the level of the cochlear nucleus (CN), the auditory pathway divides into several parallel circuits, each of which provides a different representation of the acoustic signal. Here, the representation of the power spectrum of an acoustic signal is analyzed for two CN principal cells-chopper neurons of the ventral CN and type IV neurons of the dorsal CN. The analysis is based on a weighting fu...

Single-unit responses to infinitely iterated rippled noise and wideband noise were recorded from the cochlear nucleus of anesthetized chinchillas. Rippled noises had a fixed delay of 4 ms, and spectral depth was varied by attenuating the delayed version of the noise. Temporal discharge patterns were analyzed using neural autocorrelograms, and responses to rippled noises were compared to wideban...

Owing to the increasing demand in the urban areas for new technologies such as heat pumps and electric vehicles (EVs), greater power capacity in low voltage (LV) distribution networks is becoming increasingly important. This study will investigate how to improve the power capacity through the implementation of point of use voltage regulation (PUVR). PUVR relies on a power electronics converter ...

OBJECTIVE To determine the operative advantage in terms of minimizing the complications following conventional phaco surgery with dual infusion through irrigating chopper. METHODS A Randomized Controlled Clinical Trial (RCCT) was conducted in the Ophthalmology Unit-III, Sindh Government Lyari General Hospital and DUHS and Al-Noor Eye Hospital Karachi, from March 2008 to February 2009. A total...
