buckling of viscoelastic composite plates using the finite strip method
در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
Segmenting Multiple Textured Objects Using Geodesic Active Contour and DWT
We address the issue of segmenting multiple textured objects in presence of a background texture. The proposed technique is based on Geodesic Active Contour (GAC) and can segment multiple textured objects from the textured background. For an input texture image, a texture feature space is created using scalogram obtained from discrete wavelet transform (DWT). Then, a 2-D Riemannian manifold of ...
متن کاملSubependymal injuries in anterior horns of lateral ventricles and saggital rotational acceleration applied to the head
The authors histopathologically surveyed 12 autopsy cases with fatal head traumata, especially regarding neural tissue injuries at the anterior horns of the lateral ventricles, compared with 32 control cases with no head traumata. Traumatic injuries, including axonal injuries as well as hemorrhages, tearing of white matter and neurofilamentcontaining hypertrophic astrocytes were observed in the...
متن کاملStripe Chromakey Using Active Contour Models
In this paper, we propose a new region extraction and image composition method with chromakey using a two-tone striped background and active contour models. Conventional chromakey techniques using a monochromatic background have a problem that objects are regarded as the background if their colors are the same. Therefore, we utilize adjacency conditions between two-tone striped areas on the bac...
متن کاملSurface Reconstruction Using Active Contour Models
Variational Methods have been frequently used for surface reconstruction and contour extraction (snakes). We present a surface reconstruction method where we assume the surface composed of two regions of di erent types of smoothness. One region of the surface models a \lake" (constant height region with uphill borders). It is surrounded by the other background region which is reconstructed usin...
