In this paper we design the low-power CMOS limiting amplifier using negative impedance, the purpose of using negative impedance is to increase the gain of the amplifier. low-power operations are also done using all the active elements. The LA was implemented in a standard CMOS 0.18um technology. This limiting amplifier is designed for the instrumentation(bio-medical) application. Gain of the am...

This paper introduces a notion of full abstraction for equational languages under which each language has a unique fully abstract model which can also be characterized as the $na/ object in a category of coherent computable models for the language. We describe two potentially different approaches to limiting completeness with respect to the fully abstract model-a traditional one based on normal...

In this paper, the impacts of installing superconducting fault current limiter (SFCL)in radial and loop power distribution system are evaluated to improve voltage sag in both cases of with and without distributed generations (DG). Among various SFCLs, the hybrid type with a superconducting element in parallel with a current limiting reactor (CLR) is selected. This is more effective than resisto...

A mathematical model of microbial competition for limiting nutrients and for a limited set of available wall-attachment sites in an advection-dominated tubular reactor is formulated as a limiting case of the more general model considered in [M. Ballyk and H. L. Smith, A flow reactor with wall growth, in Mathematical Models in Medical and Health Sciences, M. Horn, G. Simonett, and G. Webb, eds.,...

DC faults cause severe disruption in not only the system but also AC because fault current is very large and rapidly increases. The circuit breaker used to separate from power still being researched, it expensive due use of multiple semiconductors interrupt a short time. However, if quench characteristic superconductor used, amplitude can be reduced. Therefore, possible effectively even relativ...

The heat flux on the divertor plate of a fusion reactor is probably one of the most limiting constraints on its lifetime. The current heat flux profile on the outer divertor plate of a device like the International Thermonuclear Experimental Reactor (ITER) is highly peaked with narrow profile. The peak heat flux can be as high as 30-40 MW/m 2 with full width at half maximum (FWHM) of the order ...

We consider a nonparametric CUSUM test for change in the mean of multivariate time series with time varying covariance. We prove that under the null, the test statistic has a Kolmogorov limiting distribution. The asymptotic consistency of the test against a large class of alternatives which contains abrupt, smooth and continuous changes is established. We also perform a simulation study to anal...
