Research ArticleOpen accessIn the abstractMethod of Sliding Bearings Static Characteristics CalculationVladimir Nikolaevich Beschastnyh, Pavel Viktorovich BulatThe direct problem of researching the load capacity of segment gas-static bearing is being discussed. In calculation the movement of the shaft in the bearing is considered slow comparing than the rotational velocity. Vibrations and the influence of non-stationarity are neglected. The given geometry of the bearing and the pressure of lubrication supply in the gap between the bearing and … …American Journal of Applied Sciences, Vol. 11, Issue 11 · 7 Jan 2015 · 6,513 accessesView PDFCite
Research ArticleOpen accessIn the abstractWeb Document Segmentation Using Frequent Term Sets for SummarizationChitra Pasupathi, Baskaran Ramachandran, Sarukesi KarunakaranQuery sensitive summarization aims at extracting the query relevant contents from web documents. Web page segmentation focuses on reducing the run time overhead of the summarization systems by grouping the related contents of a web page into segments. At query time, query relevant segments of the web page are identified and important sentences from these segments are extracted to compose … …Journal of Computer Science, Vol. 8, Issue 12 · 19 Dec 2012 · 6,672 accessesView PDFCite
Research ArticleOpen accessIn the abstractActive Faulting and Quaternary Landforms Deformation Related to the Nain FaultAbolghasem Gourabi, Mojtaba YamaniProblem statement: Landforms developed across terrain defining boundary the Nain fault have imprints of recent tectonic activity in the west region of Central Iran. Depositional landforms such as alluvial fans bear signatures of later phases of tectonic activity in the form of faulting of alluvial fan deposits and development of fault traces and scarps within 100 km long and a … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 2 Nov 2011 · 7,823 accessesView PDFCite
Research ArticleOpen accessIn the abstractSRBIR: Semantic Region Based Image Retrieval by Extracting the Dominant Region and Semantic LearningI. Felci Rajam, S. ValliProblem statement: The Semantic Region Based Image Retrieval (SRBIR) system that automatically segments the dominant foreground region, consisting of the semantic concept of the image, such as elephants, roses and does the semantic learning, is proposed. Approach: The system segments an image into different regions and finds the dominant foreground region in it, which is the semantic concept of that … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 7,026 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Modified Gaussian Mixture Model for Color-Texture SegmentationM. Sujaritha, S. AnnaduraiProblem statement: This study presents a new, simple and efficient modified Gaussian mixture model based clustering algorithm for color-texture segmentation. The proposed mixture model introduces a new component density function which incorporates spatial information and the weighting factor for neighborhood effect is fully adaptive to the image content. Approach: It enhances the smoothness towards piecewise-homogeneous segmentation and reduces the edge-blurring … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,329 accessesView PDFCite
Research ArticleOpen accessIn the abstractProsody Modification of Standard Arabic Speech Using Combining Synchronous Overlap and Add With Fixed-Synthesis Algorithm and Multi Level Discrete Wavelet TransformYkhlef Faycal, Bensebti Mesaoud, Bendaouia LotfiProblem statement: The objective of prosody modification is to change the amplitude, duration and pitch (F0) of speech segments without altering their spectral envelop. Applications are numerous, including, Text-To-Speech synthesis, transformation of voice characteristics and foreign language learning. Several approaches have been developed in the literature to achieve this goal. The main restrictions of these latter are in the modification … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 6,836 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study of Fatigue Data Editing using the Short-Time Fourier Transform (STFT)S. Abdullah, C. K.E. Nizwan, M. Z. NuawiThis study presents the development of the STFT-based fatigue data editing technique that will be used as a tool to accelerate for accelerating fatigue testing. This technique was performed by removing low amplitude cycles contained in the original signal in order to produce a shortened signal using the Short-Time Fourier Transform (STFT) parameter. The effectiveness of STFT power spectrum was … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 8,422 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Torsion on Externally Prestressed Segmental Concrete Bridge with Shear KeyM. A. Algorafi, A. A.A. Ali, M. S. Jaafar et al.Externally Prestressed Segmental (EPS) concrete box sections are widely used in the construction of bridge structures today. EPS concept has become an attractive tool for rehabilitation and strengthening of existing bridges which have insufficient strength and/or excessive deflection and cracking. Problem statement: EPS bridges are affected by combined stresses (bending, shear, normal, and torsional) at the joint interface between the … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,428 accessesView PDFCite
Research ArticleOpen accessIn the abstractLectin Histochemistry Assay in Colon Tissues for Inter-species CharacterizationFaezeh Yazdani Moghaddam, Jamshid Darvish, Nasser Mahdavi Shahri et al.Problem statement: The digestive tract of animals including rodents has taxonomic and ecologic importance due to its ability in adaptation for different environments. Whereas colon absorbs water and carbohydrates, it has a vital role ecologically and physiologically and enjoys different histological structures in different rodents with various diets. Approach: Different rodent specimens belong to the family Muridae, namely Gerbilinae subfamily … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 8,685 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Improved TCP Connection Protocol over Wireless Mobile Networks with Mobile Nodes HandoffMaen M. Al AssafProblem Statement: This study proposes a TCP layer protocol (Div-TCP) that aims to give a solution for communication over wireless mobile networks that have the occurrence of handoff at anytime. It describes a topology of wireless mobile network and the handoff process as an ordinary process in that type of networks which may cause segments losses. Approach: Wireless mobile networks … …Journal of Computer Science, Vol. 4, Issue 8 · 31 Aug 2008 · 6,675 accessesView PDFCite
