The number reduction task (NRT) allows us to study the transition from implicit knowledge of hidden task regularities to explicit insight into these regularities. To identify sleep-associated neurophysiological indicators of this restructuring of knowledge representations, we measured frequency-specific power of EEG while participants slept during the night between two sessions of the NRT. Alph...

Various proposals have been made for new paradigms for operating the restructuring electrical system. One of the key challenges associated with this restructuring is to effectively analyze and evaluate the effects these alternative paradigms may have on major aspects of power system operations, including the so called ancillary services. This paper provides preliminary results on the developmen...

–A Power quality problem is an occurrence manifested as a nonstandard voltage, current or frequency that results in a failure or a mis-operation of end user equipments. Utility distribution networks, sensitive industrial loads and critical commercial operations suffer from various types of outages and service interruptions which can cost significant financial losses. With the restructuring of p...

We study the development of conjunctive keyword searchable scheme which enables one to search encrypted documents by using more than one keyword. The notion of conjunctive keyword searching was presented by Golle et al. in 2004. However, their security model was constructed in a symmetric-key setting which is not applicable for the overall applications in the reality. So Park et al. extended Go...

In this paper we present several proofs on the extension of M. Riesz fractional integration and di¤erentiation to the contexts of spaces of homogeneous type and measure metric spaces with non-doubling measures. 1. Introduction, some de…nitions, and a basic lemma Professor M. Ash asked me to write a survey article on some of the results that Stephen Vági and I obtained in the nineties on fractio...

Protection practices in electric utility industry as it existed prior to re-structuring were designed to meet certain goals of sound engineering principles as they were applied, primarily to component protection in vertically integrated electric utility systems. There has been a significant shift in emphasis from uncomplicated component protection to system protection to avoid or mitigate wide-...
