Power dissipation in technology mapped circuits can be reduced by performing gate re-sizing, that is, slowing down gates without decreasing the speed of the logic network. Recently we have proposed a symbolic procedure which exploits the compactness of the ADD data structure to accurately calculate the arrival times at each node of a circuit for any primary input vector. In this paper we extend...

This study evaluates the discriminative power of sequential spectrum analysis of the short-term electrocardiogram (ECG) time series in separating normal and subjects with life threatening arrhythmias like, ventricular tachycardia/fibrillation (VT/VF). The raw ECG time series is transformed into a series of binary symbols and the binary occupancy or relative distribution of mono-sequences (i.e. ...

Adder being the basic hardware block of any arithmetic operation, the major constraint in the field of signal processors, data processors to perform any operations are highly dependent on the adder performance of the circuit. The gate level implementation of the carry select adder (CSLA) and modified carry select adder has significantly reduced the area and power consumption which replaced the ...

The more sophisticated a protection algorithm, the more information on both steady-state and transient behavior of a protected element required for proper designing, setting and testing of a given relay. In the case of a power transformer, the most important phenomena to be modeled from the standpoint of protective relaying are: magnetizing inrush including initial, recovery and sympathetic inr...

AIM To investigate the potential usefulness of contrast-enhanced three-dimensional (3D) power Doppler sonography in the differentiation of benign and malignant adnexal lesions. METHODS Thirty one patients with complex adnexal lesions of uncertain malignancy at transvaginal B-mode and/or color Doppler sonography were prospectively evaluated with three-dimensional power Doppler sonography befor...
