Research ArticleOpen accessIn the abstractMultiaxial Fatigue Strength to Notched specimens made of 40CrMoV13.9Abedin Gagani, Raffaella Aversa, Relly Victoria V. Petrescu et al.Fatigue is a process (succession of mechanisms) which under the action of time-varying strains or deformations modifies the local properties of a material. These can lead to the formation of cracks and eventual rupture of the structure. Fatigue is in particular characterized by an extent of variation in stress which may be well below the yield strength of the material. … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 31 Dec 2016 · 8,200 accessesView PDFCite
Research ArticleOpen accessIn the abstractNon-Singular Thermodynamic GravityPharis E. WilliamsNewton formed his laws of motion, but still had to assume a law of gravity in order to determine the motions of bodies interacting through gravitational forces. Newton gave a prescription of how to find the dynamics produced by gravity. Einstein sought to determine the motions of gravity without using a force. Rather, he sought a system of equations by … …Space Science International, Vol. 1, Issue 2 · 23 Dec 2013 · 7,651 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Behavior of Tyre Tread BlockK. Sridharan, R. SivaramakrishnanThe Tyre tread pattern is the arrangement of blocks, grooves and voids, sipes and channels designed into the tread to enhance its grip on the road. Tread is the uppermost part of any tyre which contact into the road and it has its own performance towards mileage, traction, low noise and heat built up properties. It would be meaningful to … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 28 Jul 2012 · 9,791 accessesView PDFCite
Research ArticleOpen accessIn the abstractContent Based Image Retrieval of Ultrasound Liver Diseases Based on Hybrid ApproachR. Suganya, S. RajaramProblem statement: In the past few years, immense improvement was obtained in the field of Content-Based Image Retrieval (CBIR). Nevertheless, existing systems still fail when applied to medical image databases. Simple feature-extraction algorithms that operate on the entire image for characterization of color, texture, or shape cannot be related to the descriptive semantics of medical knowledge that is extracted from … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 24 Mar 2012 · 7,643 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Method to Describe Image Theory for an Imperfect ConductorScott L. Meredith, Susan K. Earles, Niescja E. TurnerProblem statement: Modify the equations associated with image theory in order to account for perfect and imperfect conductors. Approach: A novel approach for describing the application of image theory for an imperfect conductive surface was presented. The method presented here purposely downplays the physics of how image theory was employed to account for a charge which is in the presence … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 30 Jun 2010 · 7,721 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Linear Switched Reluctance Machine: Analysis and Experimental VerificationN. C. Lenin, R. ArumugamThe important problems to be solved in Linear Switched Reluctance Machines (LSRMs) are: (1) to design the shape and size of poles in stator and translator cores; (2) to optimize their geometrical configuration. A novel stator geometry for LSRMs that improved the force profile was presented in this study. In the new geometry, pole shoes were affixed on the stator … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,255 accessesView PDFCite
Research ArticleOpen accessIn the abstractPullout Characterizations of Various Steel Fibers Embedded in Very High-Strength ConcreteSameer Hamoush, Taher Abu-Lebdeh, Toney Cummins, Brian ZornigProblem statement: There is a real need for a fundamental understanding of bond and bond mechanisms in the newly developed Very-High-Strength-Concrete (VHSC) materials. The interfacial steel fiber/VHSC matrix bond tests are needed to characterize VHSC and to aid in the development of analytical models that describe bond behavior of this new material. Approach: This research investigated bond-slip characteristics of four … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractSeparable Watermarking Technique Using the Biological Color ModelDavid Nino, Moussa Abdallah, Bassam HammoProblem statement: The issue of having robust and fragile watermarking is still main focus for various researchers worldwide. Performance of a watermarking technique depends on how complex as well as how feasible to implement. These issues are tested using various kinds of attacks including geometry and transformation. Watermarking techniques in color images are more challenging than gray images in terms … …Journal of Computer Science, Vol. 5, Issue 8 · 31 Aug 2009 · 6,611 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpatial Color Indexing: An Efficient and Robust Technique for Content-Based Image RetrievalRachid Alaoui, Said Ouatik El Alaoui, Mohammed MeknassiProblem statement: Color Histogram is admitted as a useful representation of features because it is a statistical result and possesses the merits of simplicity, robustness and efficiency. However, the main problem with color histogram indexing is that it doesn't take into account the spatial information. Previous researches have proved that the effectiveness of image retrieval increases when spatial feature of … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 7,418 accessesView PDFCite
