Synopsis The yield-line method of analysis provides a powerful means of identifying the ultimate load carrying capacity of reinforced concrete slabs. Benefits of the yield-line method are that it will often identify additional reserves of strength when applied to the analysis of existing slabs, and to highly economic slabs when used in design. Traditionally a hand-based method, the yield-line m...

The steady time-averaged flows in a rotating system of immiscible fluids are studied experimentally. fill horizontal cylindrical container and brought into centrifuged state, when less dense fluid forms core, denser is distributed the form coaxial layer. Under action gravity field, core steadily displaced along radius such way that its axis oriented parallel to remains stationary laboratory fra...

The study of the propagation and evolution of interplanetary disturbances, shocks and discontinuities through the magnetosheath is critical to improve our understanding of the Sun-Earth system. It’s necessary to study interaction of the Earth’s Bow Shock (BS) with interplanetary discontinuities, because the interactions influence the Earth’s magnetosphere. In this paper we discuss various types...

This paper presents a Continuous-Curvature Path Planner (CCPP) for a car-like robot. Previous collision-free path planners for car-like robots compute paths made up of straight segments connected with tangential circular arcs. The curvature of this type of path is discontinuous so much so that if a car-like robot were to actually follow such a path, it would have to stop at each curvature disco...

Instead of ‘researching’ for perfected (yet rejected) solutions, IMAG-DLO stresses the need for a farmer participatory approach towards: local development of less perfect, yet accepted practical and low-cost technologies; based on simple and durable equipment designs suitable for local manufacture.

Introduction: The purpose of this study was to estimate the secondary cancer risk of thyroid for standard radiotherapy methods which are commonly used for breast cancer patients. Materials and Methods: Sixty-four breast cancer patients (their age range was around 50 years old) who referred to Seyed- Al- Shohada hospital (Isfahan, Iran) were included in this ...

background: providing a cross-sectional image is essential for preimplant assessments. computed tomography (ct) and cone beam ct (cbct) images are very expensive and provide high radiation dose. tangential projection is a very simple, available, and low-dose technique that can be used in the anterior portion of mandible. the purpose of this study was to evaluate the accuracy of tangential proje...

The results of a theoretical study on Benjamin–Ono (BO) soliton evolution are presented in simple model two-layer ocean with shear flow and viscosity. upper layer is assumed to move constant speed relative the lower tangential discontinuity profile. It shown that long-wave approximation, such can be appropriate. If supercritical, i.e., its (U) exceeds long linear waves (c1), then BO solitons ex...
