This paper investigates the problem of optimal lossy encoding of object contours in the Inter mode. Contours are approximated by connected second-order spline segments, each defined by three consecutive control points. Taking into account correlations in the temporal direction, control points are chosen optimally in the rate-distortion (RD) sense. Applying motion to contours in the reference fr...
Traditionally, wind analysis procedures based on the ‘‘gust loading factor’’ approach and experimental techniques involving the high frequency base balance and the ‘‘stick-type’’ aeroelastic model test have assumed ideal structural mode shapes, i.e., linear lateral modes and uniform torsional modes. The influence of nonideal mode shapes manifests itself through modifications in the generalized ...
Delamination monitoring in carbon fiber reinforced polymer (CFRP) laminated plates is crucial to ensure the integrity and safety of the structures that accommodate the plates. To identify delaminations in CFRP laminated plates, the two-dimensional (2D) curvature mode shape method is a prevailing method that features instant and simultaneous determination of the presence and location of the dela...
چکیده: مقدمه و هدف: آگاهی از آناتومی کانال خصوصاً در آناتومی های پیچیده مثل کانال های c-shape برای انجام یک درمان موفق ضروری می باشد. از آنجا که در کانال های c-shape نحوه ارتباط از کرونال تا آپیکال در نحوه درمان انجام شده مهم است تشخیص وضعیت آناتومیک این کانال ها می تواند اهمیت زیادی داشته باشد. در این مطالعه، مقایسه ای بین پنج روش مختلف برای تشخیص آناتومی c-shape انجام گرفته تا روشی دقیق برای...
the most important quality indicator of fruits is the flesh firmness which is well correlated to their young’s modulus. in this research variation of vibration characteristics (shape modes, natural frequency) of apple due to change of material characteristics (density, young's models, poisson ratio) and apple volume was investigated using finite element simulation. an image processing technique...
