Previous research has indicated a qualitative resemblance between the current distribution along actively corroding crevice walls and currents measured in corresponding anodic polarization plots. Using detailed measurements of the potential gradient along the crevice, a semi-quantitative current distribution was calculated for the crevice wall using a double numerical differentiation method. Th...

This paper deals with Enhanced Phase Locked Loop Control scheme for Distributed Static Compensator (DSTATCOM) in the distribution system. The proposed control scheme based DSTATCOM eliminates current harmonics, maintains unity power factor at source, zero voltage regulation and load balancing. The Enhanced Phase Locked Loop (EPLL) Control scheme is based on Digital Signal Processing (DSP) which...

in this paper, the impacts of installing superconducting fault current limiter (sfcl)in radial and loop power distribution system are evaluated to improve voltage sag in both cases of with and without distributed generations (dg). among various sfcls, the hybrid type with a superconducting element in parallel with a current limiting reactor (clr) is selected. this is more effective than resisto...

Web information contain plentiful, significant knowledge which is eager to be explored by users. Effective semantic layered technology not only can provide theoretical support for knowledge discovery in Web resources, but also can improve the searching efficiency of the related information system. This paper builds the multi-layer theory of association semantic based on the power-law distributi...

BACKGROUND Current sepsis screening tools rely on vital parameters which are, however, normal in one third of patients with serious infections. Therefore, there is a need to include other variables than vital parameters to identify septic patients. Our primary aim was to identify and quantify keywords related to the septic patients' symptom presentation in the prehospital setting. The secondary...

Currently a new version of the distance education platform WeLearn [3] to be combined with an agent system ([1], also developed locally) for providing advanced services [2] is under development. In a previous stage of the project software was created to automatically derive keywords from documents, either from the different versions of metadata already contained (various Microsoft file formats,...

As our ability to store information increases, the mechanisms we employ to access that information become ever more important. In this paper, we present Archosum, a prototype of an organizational system that attempts to encapsulate the benefits of both hierarchical and keyword systems. By introducing abstract entities, Archosum provides a simple interface with which users can build and maintain...
