<p>Increased use of wireless technologies and in turn more utilization available spectrum is subsequently leading to the increasing demand for spectrum. This research work incorporates sensing detection consisting a double dynamic threshold followed by cooperative type sensing. The performance has been analyzed using two modulation schemes, quadrature-amplitude-modulation (QAM) & ...

Power management strategies play a key role in the design process of hybrid electric vehicles. Electric Assist Control Strategy (EACS) is one of the popular power management strategies for hybrid electric vehicles (HEVs). The present investigation proposes a new framework to advance the EACS. Dynamic Programming method is applied to an HEV model in several drive cycles, and as a result, some op...

A new concept in group oriented cryptography { the dynamic threshold cryp-tosystem { is presented in the paper. The dynamic system has many advantages over the existing threshold cryptosystems. It is set up by the sender who can not only compose the group of recipients but select the threshold as well. Implementations of the dynamic system based on the ElGamal and the RSA public key cryptosyste...

In this paper we investigate error-thresholds on dynamics fitness-landscapes. We show that there exists both lower and an upper threshold, representing limits to the copying fidelity of simple replicators. The lower bound can be expressed as a correction term to the error-threshold present on a static landscape. The upper error-threshold is a new limit that only exists on dynamic fitnesslandsca...

Dynamic CMOS logic circuits are used in high performance VLSI chips in order to achieve very high system performance. These circuits requires less number of transistors as compare to CMOS logic circuits Dynamic logic circuits are much affected by noise as compared to static CMOS circuit. This is due to the fact that dynamic logic circuits have lower value of switching threshold voltage, which i...

The project suggests effective motion recognition built on background subtraction using dynamic threshold approach with mathematical morphology. Here the techniques frame differencing, dynamic threshold based detection will be used. In addition to dynamic threshold, mathematical morphology is also used within ability of greatly attenuating color dissimilarities has generated by background motio...
