The population of students all over the world is growing without a proportionate increase in teaching/learning resources/infrastructure. There is also much quest for learning in an environment that provides equal opportunities to all learners. The need to provide an equal opportunity learning environment that will hitherto improve the system of education globally has therefore become imperative...

This paper describes the implementation of Distributed Active Filters (DAFs). To share the workload of harmonic filtering, several Active Filter Units (AFUs) are placed on different locations which can perform the harmonic filtering without a direct communication. Different configurations of DAFs are described and are implemented using MATLAB /Simpower system Toolbox environment to observe thei...

The KM3NeT consortium aims at the construction of a research infrastructure in the Mediterranean deep sea, hosting a neutrino telescope with an instrumented volume of several km3 and an integrated platform for earth and deep sea sciences. The telescope location in the Mediterranean Sea will allow for surveying a large part of the Galactic Plane, including the Galactic Centre, thus complementing...

We have analyzed the vulnerability and threat of the biometric evaluation database and proposed the method to generate a synthetic database from a real database. Our method is characterized by finding nearest neighbor triples or pairs in the feature space of biometric samples, and by crossing over those triples and pairs to generate synthetic samples. The advantages of our method is that we can...

Active Learning (AL) methods seek to improve classifier performance when labels are expensive or scarce. We consider two central questions: Where does AL work? How much does it help? To address these questions, a comprehensive experimental simulation study of Active Learning is presented. We consider a variety of tasks, classifiers and other AL factors, to present a broad exploration of AL perf...

Explosive growth of applications for wireless networks and increasing number of users will cause significant increase in the traffic over radio channels. Consequently, uplink and downlink channels may suffer serious traffic congestion problems in the absence of effective congestion control schemes. One approach to enhance the performance of wireless services is to employ an AQM scheme for buffe...

Different rule execution semantics may be available in the same active database system. We perform several simulation experiments t o evaluate the performance trade-offs yielded b y different execution semantics in various operating conditions. In particular, we evaluate the eflect of executing transaction and rule statements that a f f ec t a varying number of data instances, and applications ...
