Oxalate biosensors (OBs) are based on either measurement of oxygen or electrons generated from splitting of H 2 O 2 or heat released during oxidation of oxalate by immobilized oxalate oxidase. OBs are grouped in four classes based on probe used (DO meter, electrochemical, SIRE technology and thermochip). OBs work optimally at: time, 5 s to 15 min; pH, 2.8 8.0; temp., 30 38°C and linearity, 1.0 ...

Optical Burst Switching (OBS) is the future of optical internet which provides a promising architecture to efficiently utilize WDM and to fulfill today‘s Internet traffic demands. Since this area is yet to mature there is a darn need to study its various protocols. Network simulator is an important tool for researchers and academicians to simulate and model the actual network at a reduced cost ...

The need for accurate provisional restorations has led to the introduction of a multitude of materials for the same, with considerable variation in physical, chemical and biologic properties. Polymethylmethacrylatebased materials have long dominated the arena of provisional restorative materials, but the advent of newer resin based materials with superior handling characteristics has broadened ...

This paper briefs about the Partial Transmit Sequences for Peak-to-Average Power Ratio Reduction of OFDM Signals, PAPR reduction efficiency of this method in comparison with Companding and Clipping and some merits and demerits of using various methods of PAPR reduction. Based on the above survey the criteria for the selection of PAPR reduction is given and proposed scheme of combining PTS appro...

It unpacks technicalities, merits, demerits team-authoring materials context revitalisation indigenous languages within Zimbabwe’s education system. The main focus is on technical compilation design textbook series. evaluates approaches that were used development Namby...

We discuss techniques for Voice Activity Detection (VAD) for Voice over Internet Protocol (VoIP). VAD aids in reducing bandwidth requirement of a voice session thereby using bandwidth efficiently. Such a scheme would be implemented in the application Layer. Thus the VAD is independent of the lower layers in the network stack [3]. In this paper, we compare four time-domain VAD algorithms in term...

This paper, explain a comprehensive survey of recent medium access control (MAC) Protocols for wireless body area networks (WBANs) and presents a comparison of the various approaches pursued. Apart for this, we outline the crucial attributes for a good MAC. Then, we investigate few MAC Based protocols devised for WBAN by emphasizing their Merit and Demerits. As a conclusion, we put forward a nu...

This paper analyzes the merits and demerits of global weak-indication self-timed function blocks versus local weak-indication self-timed function blocks, implemented using a delay-insensitive data code and adhering to 4-phase return-to-zero handshaking. A self-timed ripple carry adder is considered as an example function block for the analysis. The analysis shows that while global weak-indicati...
