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....
Shape Measurement by Phase-Stepping Method Using Multi-Line LEDs
Three-dimensional shape measurement is used in various fields such as robotics and inspection of industry production. It is requested to measure shape with high speed and high accuracy. It is also requested to make the system compact and low-cost. It is, however, difficult to satisfy these requests simultaneously for 3D shape measurement. In order to measure shape in real-time, Kato et al. prop...
متن کامل3D shape modeling by color phase stepping light projection
Color encoded phase-stepping light projection method is a new and promising technique for 3D shape modeling However, the 3D model acquired is often smeared by large error. The main cause of the error is color coupling amongst the three primary colors RGB. In this paper, we first analyzed the color-coupling problem. It is found that there is a strong coupling between G and R element. The couplin...

3D Object Retrieval Using Compact Shape Descriptor
The need for effective and efficient 3D object retrieval approaches is emerging in a broad range of applications in science and engineering. With the increasing understanding of shape geometry and topology in the context of shape similarity, workable solutions for 3D object retrieval are being produced. In this paper, we present a novel technique for 3D Object Retrieval. The key idea of the pro...
