Research ArticleOpen accessIn the abstractDesign of a Symmetrical Microstrip Bandpass Filter for S-Band Frequency RangeMohd Fadzil Ain, Mandeep Singh Jit Singh, Prabhu, Syed Idris Syed HassanA new type of microstrip bandpass filter is presented with a center frequency operation at 2.5GHz which lies in the S-band frequency range. The filter is designed to be much smaller compared to the same type of parallel-coupled bandpass filter. The simulation results are excellent and the filter is suitable for integration within various microwave subsystems. …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 6,984 accessesView PDFCite

According to registry and survey data, most immigrant businesses - and particularly those owned by immigrants from less developed countries in Asia, the … …Journal of Social Sciences, Vol. 3, Issue 2 · 30 Jun 2007 · 7,459 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element Analysis of Plasticity- Induced Fatigue Crack Closure with Singular ElementR. Rahgozar, H. Saffari, R. TabatabaeiDeveloping a new method is presented to compute crack opening values in planar geometries using the crack surface nodal force distribution under minimum loading as determined from finite element analyses (FEM). In this technique, two-dimensional elastic-perfectly plastic finite element analyses of middle-crack tension (MT) geometry is conducted to study fatigue crack closure and to calculate the crack opening values under … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 6,850 accessesView PDFCite
Research ArticleOpen accessIn the abstractAgrobacterium-mediated Genetic Transformation in Cucumber (Cucumis sativus L.)A. Vasudevan, N. Selvaraj, A. Ganapathi, C.W. ChoiThe present study was undertaken to develop efficient transformation protocol for cucumber cv. Poinsett 76 using Agrobacterium strain EHA 105. Five-day-old mature cotyledon explants was used for transformation study. The infected explants were co-cultivated for 2 days in MS medium containing BA (1.0 mg Lˉ1). The selection of transformed shoots was carried out in MS medium fortified with BA (1.0 … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 1 · 31 Mar 2007 · 8,901 accessesView PDFCite
Research ArticleOpen accessIn the abstractInformatics and Physics Models of Recognitions of DNA Replication and Their Biological ApplicationsKang Cheng, Chang Hua ZouWe initially propose concepts of Informative Intensity, Informative Response Intensity and Informative Flux, with different expressions. In a special expression of electrostatics, we describe Informative Intensity, Informative Response Intensity and Informative Flux in terms of electric field intensity, electric field force and electric field flux respectively. In a special expression of quantum mechanics, we originally propose a concept of Probability … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 6,869 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Integrated Approach to Digital Objects Storage and RetrievalKhalil Shihab, Haider Ramadhan, Nida Al-ChalabiImage retrieval systems are becoming increasingly important in areas of research and commercial use. The storage of digital objects in the traditional databases is considered inadequate because of the extensive precise data required for successful retrieval. In addition, the retrieval process has been implemented using content-based image retrieval (CBIR) that relies on retrieving stored images from a collection by comparing … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,491 accessesView PDFCite

OnwuboluThe local Principal Component Analysis (PCA) reduces linearly redundant components that may present in higher dimensional space. It deploys an initial guess technique which can be utilized when the distribution of a given multivariate data is known to the user. The problem in initialization arises when the distribution is not known. This study explores a technique that can be easily … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,719 accessesView PDFCite
Research ArticleOpen accessIn the abstractRiemann Estimation for Replicated Environmental Sampling DesignsLucio Barabesi, Marzia marcheselliIn many environmental surveys the population under study is made up of biological units scattered over a planar region. A variable is considered on each unit and the target parameter generally turns out to be the population total of the variable. In order to estimate the population total, field scientists commonly replicate a suitable design on the study region.
