Security is a vital issue to be taken care of and to be experienced with different perspectives and preventive measures. In the present time, entire web is coming nearer from content information to mixed media information. One of the real security concerns is the insurance of this sight and sound information. Picture, which covers the most noteworthy rate of the media information, its assurance is...
This paper presents a low voltage, low power CMOS OTA that can be used in high frequency applications. The basic topology using differential input single output OTA is simulated in TSMC 90nm CMOS process technology. The simulation results indicate high bandwidth, greater than 10GHz with 0.721mW power consumption and the transconductance of -69.78dB. The total harmonic distortion for 100mV input at...
Videos are a powerful and expressive media that can capture and present information. As these videos cover many subjects / genres, it is critical task to segregate videos as per the needs or interest of the users which requires classifications. In this paper we present a model for video classification using embedded audio. Video classification is usually accompanied with video annotation which helps...
This paper presents a modelling, simulation and Implementation of topology of single-phase AC-DC active rectifier having power factor correction (PFC). This converter topology is evaluated on the basis of performance and its salient features are discussed to analyze its applicability. The technique not only helps to develop a deeper understanding of this converter but also to evaluate performance...
The aim of this paper is to introduce a new multipurpose human machine interface (HMI) designed using higher level language. Unlike any other software, wherein if hardware is changed; there is a need to bring subsequent change in the software; this HMI can be used as a general purpose software for ECG analysis with any kind of hardware. The same analyzing system can be used to perform allied other...
The progress in portable computing in the past few decades has provided the means with PC or customized microcomputer based instrumentation to develop solutions to biomedical problems that could not be approached before. Detection of irregularities in the rhythms of the heart using customized microcomputer based instruments is a growing field in medical research. This paper gives an emphasis on the...
Design of the binary logic circuits is limited by the requirement of the interconnections and a possible solution can be achieved by using a larger set of signals over a similar chip area, such as multiplevalued logic (MVL) designs. Quaternary logic and number systems are known to offer certain advantages over their binary counter part due to larger information per symbol carried by the former. Common...
