Research ArticleOpen accessIn the abstractSupplying a Common Distribution Load through Two Different SourcesM. H. Naeem, K. P. BasuPhase angle difference between any two Busbar voltages of a big power system varies with the loading and operating condition of the power system. Supplying a common distributed load from these two phase shifted sources needs the application of a controlled phase shifter. Three-phase tapped autotransformer connected in delta with properly controlled variation of input and output tap settings may … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,495 accessesView PDFCite

Research ArticleOpen accessIn the abstractKorovkin and Weierstrass Approximation via Lacunary Statistical SequencesRichard F. Patterson, Ekrem SavaşIn this study we shall extended Korovkin and Weierstrass approximation theorem to lacunary statistical convergent sequences. In addition, to these approximation theorems, we established also introduced lacunary statistically convergent of degree β and establish a corresponding Korovkin type theorem namely the following: If the sequence of positive linear operators Pn: CM [a, b]→ B[a, b] satisfies the conditions: * ||Pn(1, … …Journal of Mathematics and Statistics, Vol. 1, Issue 2 · 30 Jun 2005 · 6,659 accessesView PDFCite
Research ArticleOpen accessIn the abstractApproximation Methods for Fixed Points of Quasi-contractive Mappings in Arbitrary Real Banach SpacesOlusegun O. OwojoriOwojori and Imoru [1] introduced some iteration methods and investigated its convergence for pseudocontractive and accretive operators in arbitrary Banach spaces. In this work, strong convergence results are established for fixed points of a general type of quasicontractive mappings in arbitrary real Banach spaces. Our results here represent some improvements on the earlier results of Owojori and Imoru [1], Naimpally … …Journal of Mathematics and Statistics, Vol. 1, Issue 2 · 30 Jun 2005 · 6,155 accessesView PDFCite

Research ArticleOpen accessIn the abstractERCP Related SepsisIffet Palabıyıkoglu, Emin Tekelı, Derya Aysev et al.Endoscopic procedures performed worldwide have increased considerably in recent years. In addition to diagnosis, many cases previously necessitating surgery now often can be carried out by endoscopic techniques. However, endoscopy has introduced its own infection risk. Most reports of gastrointestinal endoscopy-associated infection describe sepsis after endoscopic retrograde cholangiopancreatography (ERCP) in patients with biliary tract obstruction. During this study, which was … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 7,016 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation and Situation of Timber Harvesting Mechanization of Turkey and the Usage of Tractors in Timber ExtractionMurat Demir, Tolga OzturkIn this study is to summarize usage of tractors in timber extraction and major problems of mechanized timber harvesting in Turkey. Timber harvesting in Turkey is still carried out by manual methods due to economical, social and environmental constraints. Almost 80% of harvesting activities are mechanized in many developed countries while this value is only 5% in Turkey.

Research ArticleOpen accessIn the abstractKernel Density Estimation for Interdeparture Time of GI/G/1 QueuesHsing Luh, Berlin WuThe departure process of a single queue has been studied since the 1960s. Due to its inherent complexity, closed form solutions for the distribution of the departure process are nearly intractable. In this study, kernel type estimators of the density of interdeparture time in a GI/G/1 queue are studied. Uniform strong consistency of the estimators in a GI/G/1 queue and … …Journal of Mathematics and Statistics, Vol. 1, Issue 1 · 31 Mar 2005 · 6,585 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproved Performance of Traffic Dependent Outage Rate Cellular SystemHussein M.A. Basi, M. B.R. MurthyThe designers of a mobile cellular system must evaluate the possible configurations of the system components and their characteristics in order to develop a system with greater efficiency. The useful parameters to estimate performances of the system are voice quality, frequency spectrum efficiency and grade of service (GOS).
