Acoustics Willis media, known as bianisotropic acoustic incorporate additional coupling between pressure and velocity momentum volumetric strain in their constitutive equation. The extra terms have a significant influence on wave behavior. In this paper, the unusual phenomena relevant to interfaces homogeneous media are theoretically studied. We show that offer more flexible control front energ...

confined masonry buildings are used in rural and urban areas of iran. they performed almost satisfactoryduring past moderate earthquakes of iran. there is not a methodology in iranian seismic code (standard 2800-3rdedition) to estimate their capacities quantitatively. in line with removing this constraint, an attempt is made to studyin-plane behavior of two squared confined masonry walls with a...

یکی از راهکارهای افزایش کارایی پردازنده های همه منظوره، استفاده از پردازنده ها با مجموعه دستورالعمل های قابل توسعه است. در این نوع پردازنده ها امکان اضافه کردن دستورالعمل های جدید برای پردازنده وجود دارد. مشکلی که برای توسعه برنامه بر روی این پردازنده وجود دارد، پیچیدگی فرایند طراحی در آنها است. انتخاب خودکار دستورالعمل های سفارشی و تشخیص آنها هزینه بالایی دارد. شناسایی دستوالعمل های سفارشی بر ...
In this paper, the linearly conforming enriched radial basis point interpolation method is implemented for the elasto-plastic analysis of discontinuous medium. The linear conformability of the method is satisfied by the application of stabilized nodal integration and the enrichment of radial basis functions is achieved by the addition of linear polynomial terms. To implement the method for the ...
Integration of the PV into the electrical grid needs power electronic interface. This power electronic interface should have some key features and should come up with grid codes. One of the important criteria is the quality and harmonic contents of the current being injected to the grid. High-order harmonics of the grid current should be very limited (lower than 0.3% of the fundamental current)...
Background and aims: Hospital personnel are exposed to various occupational hazards because of their job circumstances. The aim of this study is to investigate the ergonomic problems of hospital from the perspective of human-system interface technology and to recommend the strategies for improvement. Methods: In this qualitative study, the conceptual framework of hospital ergonomic problems ...
At present study, effects of wall thickness and porosity on the conjugate free convection heat transfer inside a square cavity have been examined. Continuity, momentum and energy equations for fluid and solid matrix phases are governing equations in present work. Mentioned equations and related boundary conditions have been transformed into their non-dimensional forms. They are solved using fin...
Soil nailing is a popular reinforcement method for stabilizing slopes, excavations, and retaining walls in many countries. The pullout capacity of the soil-nail interface is a critical parameter for the design and safety assessment of soil-nailed systems. In this paper, a three-dimensional (3D) finite element (FE) model is developed using the commercial program ABAQUS to simulate the pullout te...
