ecause stress is a leading cause of illness and disease and is so pervasive, there is an inherent need to be able to monitor stress in real time over extended periods. A real-time personal stress monitor would benefit individuals by providing continuous feedback about their stress levels and by helping their physicians to objectively evaluate stress(More)
Monitoring of the electrocardiogram during normal activity using Holter devices has become standard procedure for detection of cardiac arrhythmias, transient ischemic episodes and silent myocardial ischemia. Existing devices mostly record "twenty-four" hour activity and then perform off-line record analysis. We present realization of an intelligent(More)
This paper presents a fault classification technique for transmission lines based on the fault sequence components, for fast and reliable operation of protective relays. First, symmetrical components of fault current and voltage signals are extracted. Next, the fault type is classified using the zero and negative sequences. To realize the faulted phases in(More)
Speech processing includes the various techniques such as speech coding, speech synthesis, speech recognition and speaker recognition. In the area of digital signal processing, speech processing has versatile applications so it is still an intensive field of research. Speech processing mostly performs two fundamental operations such as Feature Extraction(More)
In harsh economic downtrends, similar to those experienced in the past few years, organizational leaders within companies sought ways to reduce operating costs to boost shareholder value. Unfortunately, most of them took a short-sighted approach by eliminating some of their human capital, one of the most valuable assets of an organization. Of course, in the(More)
In SAR applications, the size of data can be quite large, and many data compression algorithms have been developed to reduce the storage requirements for SAR data. Previous research has been done on the compression of both amplitude and raw SAR data. However, the performance metrics used in these compression schemes are often visual-related metrics such as(More)
