This study presents a novel sequential Type-I optimal normal basis multiplier in GF(2) with a regular structure. The proposed multiplier has a slightly higher space complexity than the Reyhani-Masoleh-Hasan’s (RMH) multiplier, but is 27% faster than the RMH multiplier. Furthermore, the proposed multiplier is highly regular, modular, expandable and well-suited to VLSI implementation. A new norma...

We discuss some collider signatures of the brane world. In addition to the usual bulk (closed string) fields and brane (open string) fields in the Type I string picture, there are closed string fields, namely, twisted modes, which are not confined on the branes but nonetheless are localized in the extra compactified dimensions. While the coupling of the Standard Model (brane) fields with a bulk...

We introduce a domain-theoretic foundation for disjunctive logic programming. This foundation is built on clausal logic, a representation of the Smyth powerdomain of any coherent algebraic dcpo. We establish the completeness of a resolution rule for inference in such a clausal logic; we introduce a natural declarative semantics and a fixed-point semantics for disjunctive logic programs, and pro...

A b s t r a c t -In this paper, we present a new mathematical framework in which disjunctive feature structures are defined as directed acyclic hypergraphs. Disjunction is defined in the feature structure domain, and not at the syntactic level in feature descriptions. This enables us to study properties and specify operations in terms of properties of, or operations on, hypergraphs rather titan...

The paper describes experimental results of a mediumvoltage, modular, 35 MW drive for Oil & Gas applications realized by interconnecting voltage-source three-level converters equally sharing the motor current. Drives rated for tens of Megawatts are increasingly needed as torque helpers for gas turbines in the Oil & Gas industry and one envisions that they will replace them completely in the fut...

This paper presents a simple abdomen model of pregnant women and the evaluation of the specific absorption rate (SAR) inside the proposed model close to normal mode helical antennas (NHAs), which are replacing the portable radio terminals for business at 150 MHz. First, dielectric properties of amniotic fluid and those of fetus of rabbit, which have about the same electrical properties as human...

The ever-increasing penetration of wind power integration into a power system can produce significant impacts on the operation of an interconnected power system. As the major energy conversion technology for large wind turbines, the doubly fed induction generator (DFIG) will play an important role in future power systems. Hence, the impacts of the DFIG on the low-frequency oscillations of inter...

A general approximation formula for the moment-generating function of random variables with broadly distributed logarithms is derived using a saddle-point expansion of the defining integral. As a special case, a simple and accurate approximation formula for the momentgenerating function of log-normal distributions is obtained. For 4.3 dB spread it reaches 0.5% accuracy and improves rapidly as t...

The primary goal of the this paper is to summarize field demonstrations of the feasibility of detecting changes in blade and shaft natural frequencies (such as those associated with a blade or shaft crack) on operating machinery using non-contact, nonintrusive measurement methods. Laboratory demonstration of feasibility and some special signal processing issues were addressed in Parts 1 and 2 [...

It is important to evaluate chipping productivity that often differed according to the timing of observations and varied unexpectedly. A variation in production was the major concern of stakeholders for sustainable forest operation to establish regularly attainable production schedules on many operational levels. The aim of this study was to estimate the variance of chipping productivity by usi...
