Abstract A conjugate forced convection with viscous dissipation heat transfer problem of a second-grade visco-elastic fluid past a flat plate fin has been studied. Governing equations include heat conduction equation of the fin, and continuity equation, momentum equation and energy equation of the fluid, were analyzed by a combination of a series expansion method, the similarity transformation and a second-order accurate finite-difference method. Solutions of a stagnation flow (β = 1.0) at the fin tip and a flat plate shape (wedge flow β = 0.0) on the fin surface were obtained by a generalized Falkner-Skan flow derivation.… More >

Abstract The typical Optical Character Recognition (OCR) systems, regardless the character's nature, are based mainly on three stages, preprocessing, features extraction and discrimination (recognizer). Each stage has its own problems and effects on the system efficiency such as time consuming and recognition errors. In order to avoid these difficulties this talk presents new construction of OCR system without pre-processing, features extraction and classifier for any handwriting characters using standard and advanced Image Compression techniques. The proposed algorithms obtained promising results in terms of accuracy as well as in terms of time consuming. More >

Abstract Prediction of fatigue crack growth in mechanical component is one of the most important problems to prevent catastrophic fracture accident. FEM is generally used for this purpose, but as crack shape changes during growing process, it is necessary to re-mesh for new crack shape. It is time consuming and is very difficult especially for 3-d. problem.
In this study, S-version FEM^[1][2] is employed to solve this problem, and fully automatic crack growth simulation system is made by combining with automatic mesh generationsystem. In the 3-d. field, crack tip stressconditionbecomes under mixed mode condition, and three stress… More >

Abstract Kinetics of the ordered phase growth in a melted multi-component liquid crystalline mixture subjected to a deep cooling was studied using polarizing optical microscopy. The droplets of the ordered phase revealed in the optical images across the phase transition were segmented and treated statistically. In the resulting histograms, two overlapping statistical ensembles related to two main components of the mixture were recognized. These ensembles were successfully described using principles of irreversible thermodynamics and the mean droplet diameters within both ensembles were determined. Analysis of the mean droplet diameter as a function of time allowed recognition More >

Abstract Malaria is one of the most serious infectious diseases on earth. We have about five hundred million patients with two million deaths. When a malaria parasite invades and matures inside a red blood cell (RBC), the infected RBC (IRBC) becomes stiffer and cytoadherent. We propose a numerical model of hemodynamics arising from malaria infection. Our model is based on a Lagrangian and free mesh method (particle) method. A spring network model is employed to compute elastic force generated by the deformation of IRBC membrane. Adhesive property of IRBCs to surrounding cells is also expressed by More >

Abstract The main goals of the present work are to automatically extract the contour of an object and to simulate its deformation using a physical approach. In this work, to segment an object represented in an image, an initial contour is manually defined for it that will then automatically evolve until it reaches the border of the desired object. In this approach, the contour is modelled by a physical formulation using the finite element method, and its temporal evolution to the desired final contour is driven by internal and external forces. The internal forces are defined… More >

Abstract Nanoparticles are materials with at least one dimension in the 1 to 100 nm range. Nanoparticles exhibit different physical and chemical properties due to large ratio of surface area to volume and small size effects (or quantum effects). Nanoparticles cover almost all materials including ceramics, metals, and polymers. Nanoparticles have a wide variety of applications in catalysis, electrodes, metallurgy, magnetic storage, composite materials, coatings, MEMS or NMES, cosmetics, etc. Shape, size, and dispersity have influence on the crystal structure and properties of nanoparticles. So shape, size, and dispersity are keys to controlling structure and properties… More >

Abstract It is important for a company to put themselves under the protection of patent right to keep their unique competitive advantages when they confront global competition. This issue is of particular importance in Taiwan since a growing number of Taiwanese companies have been sued by foreign competitors for patent infringement. For inverter industry, producing labor-saving, energy-saving, space-saving, high-communicational, high-functional, low-noise and cost-saving inverters become a more and more important topic.
This research investigates the state of the art of current inverter technology. By using United States Patent & Trademark Office (USPTO) database, we collect global patent… More >

Abstract A simple numerical method namely Initial Stiffness Method using finite element method has been employed to study the size effect which is prominent in concrete structures. Numerous experimental investigations performed on notched plain concrete beams subjected to three point or four-point bending have revealed the fracture process to be dependent on size of the structural member. It was found that, the nominal stress at maximum load decreases as the size of the structure increases. The nominal stress at failure on the characteristic dimension of structure is termed as size effect. This has also been explained More >
