Abstract This work presents a novel formulation for a Voronoi-type cellular material with in-plane anisotropic behaviour, showing global positive and negative Poisson’s ratio effects under uniaxial tensile loading. The effects of the cell geometry and relative density over the global stiffness, equivalent in-plane Poisson’s ratios and shear modulus of the Voronoi-type structure are evaluated with a parametric analysis. Empirical formulas are identified to reproduce the mechanical trends of the equivalent
At present, the extraction algorithm for fingerprint direction information is Mehtre, L.Hi made by. Which Mehtre proposed based on the neighborhood of the template in different directions to change the gray value of the point direction, and then statistics of the block direction of
Research efforts on preserving connectivity and coverage As aforementioned, one of the primary objectives of WSNs is to provide full coverage of an FoI as long as possible. Many tasks (i.e., targets tracking or boundary surveillance) require full coverage of FoI at any time. In this case, how to guarantee/preserve the connectivity of a WSN while achieving full coverage is critically important. Many approaches are addressed for this integrated issue. In order to determine the degree of the coverage
the XOR will return output as false.The X-Model X-OR is used in Parallel addition algorithm,Sine model X-OR is used in Listranking algorithm and finally Butterfly X-OR is used in Butterfly algorithm for the purpose of encryption. The inputs for the parallel addition algorithm are taken by using leftfingerprint acts as a plain text,right fingerprint acts as a key1 and palm acts as a key2.The parallel addition algorithm uses X-Model X-OR model which makes the inputs to do XOR operation in the format
A survey of Image Based Artistic Rendering techniques Introduction Paintings have been known to capture the human imagination since the pre-historic times. A skilled artist can evoke a range of human emotions and can portray things like appearances, playing of light in surfaces, mood etc. on the paper. Similarly, with the invention of photography in the 19th century, the artists got a new medium for their expressiveness and simulated artistic diversity. The field of non-photorealistic rendering started
Chapter I INTRODUCTION The heart is the human’s central blood pump, a motor which through arteries, veins and capillaries supplies blood to every part of the body, including the heart itself for correct functioning. Failure to deliver blood to different limbs and organs (excluding the brain) at any particular time can result in pain, numbness or loss of function for some time. However, failure to deliver blood to the heart itself, compromises its correct functioning and could result in a myocardial
