Research ArticleOpen accessIn the abstractWavelet Shrinkage in Noise Removal of Hyperspectral Remote Sensing DataHelmi Z.M. Shafri, Paul M. MatherIt is common in hyperspectral remote sensing studies to perform analysis based on derivative spectroscopy. However, this technique is particularly sensitive to noise in the data. Thus, noise removal is essential before any derivative analysis. Various methods of noise removal are described in the literature. A newly developed method based on the wavelet transform appears promising, though there is little … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 7,013 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructural Analysis of Furniture Hardware Industry in TurkeyTuncer DilikFurniture hardware plays an important role in the appearance, comfort and function of the furniture. In this study, Turkish furniture hardware companies were examined for their technical and economical characteristics, production materials, standards and surface treating methods, legal structures as well as foreign and domestic trade policies. Altogether, 67 companies accounting for 80% of the hardware production were examined. In … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 7,057 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Improvement Method for Swell Problem in Sulfate Soils that Stabilized by LimeM. JahanshahiIn this research low plasticity clay (CL) has to be mixed by varying percents of gypsum and after that this mixture would be treated with different amounts of lime, in two methods: regular application and Double application. The swell examinations would be done on these samples; and the influence of sulfates and mixing method on different quantities of swell will … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,650 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Adaptive Routing Algorithm for Ad hoc Mobile NetworksHamed S. Al-BdourThis research has examined the issues of routing in multi-hop wireless networks of mobile nodes without the need for any existing network infrastructure or administration. This is called ad hoc. The key point of this research article are selecting routing protocols which adapts quickly to routing changes when host movement is frequent, yet requires little or no overhead during periods … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,692 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Improved Scheme for Digital Watermarking Using Functional Link Artificial Neural NetworkBanshidhar Majhi, Hasan ShalabiThe present study proposes a novel technique for copyright protection by utilizing digital watermarking of Images. The watermark is embedded and detected by using Functional Link Artificial Neural Network (FLANN) and Discrete Cosine Transform (DCT). The exhaustive simulation results of the proposed scheme show improved performance over the existing methods in all cases, i.e. when the watermarked image is subjected … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,861 accessesView PDFCite
Research ArticleOpen accessIn the abstractGranulomatous Amoebic Encephalitis: Clinical Diagnosis and ManagementNaveed Ahmed KhanGranulomatous amoebic encephalitis (GAE) is a serious human disease with fatal consequences. With the mortality rate of more than 90%, it is not surprising that the majority of GAE infections are identified at the post-mortem stage. The most distressing aspect is that the high level of mortality is attributed to lack of awareness. Early diagnosis with aggressive treatment can lead … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 7,187 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. Overall ratio … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,585 accessesView PDFCite
Research ArticleOpen accessIn the abstractUse of Cross-linking to Assess Subunit Interaction of Recombinant Human Coproporphyrinogen OxidaseJason R. Stephenson, Nancy E. Thomas, Jon A. Friesen, Marjorie A. JonesTo provide further evidence for a dimeric form of coproporphyrinogen oxidase reported using the conventional hydrodynamic methods, bifunctional cross-linkers were incubated with purified, recombinant human coproporphyrinogen oxidase to determine subunit interaction in solution. The use of cross-linkers provides an effective way to demonstrate subunit association and allows for assessment of activity upon covalent cross-linking. Following incubation with selected cross-linkers, enzyme … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,594 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Reversible Method of Epiphysiodesis-An Experimental Study in RabbitsMahmood Karimi-Mobarakeh, Reza Malekpour-Afshar, Nozar Nakhaee et al.Lower limb discrepancy and angular deformities are among the most common orthopedic problems in pediatrics. All methods for correction of these deformities are irreversible and the epiphyseal growth plate is arrested. Current study describes a new reversible method of epiphysiodesis. At the first step, we decided to examine angular deformity of the knee. Seven New Zealand white female rabbits with … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 7,204 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncreasing Effectiveness of IDS to Improve Security in IntranetUmesh Kumar Singh, A. K. Ramani, Narendra S. Chaudhari, Vandana GuptaToday Intrusion Detection Systems (IDS) are becoming one of the most important tools for intranet security. Research regarding Intrusion Detection Systems (IDSs) has become more active with the recent increases in illegal accesses to computer systems. Many researchers focus only on the techniques or mechanisms for detecting intrusions automatically, without considering the security of IDSs themselves. When an intruder attacks … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 7,146 accessesView PDFCite
