We consider an ideal gas of infinitely rigid rods near a perfectly repulsive wall, and show that the interfacial tension of a surface with rods on one side is lower when the surface bends towards the rods. Surprisingly we find that rods on both sides of surfaces also lower the energy when the surface bends. We compute the partition functions of rods confined to spherical and cylindrical open sh...

Abstract Bridge resilience is a newly proposed bridge design criterion that involves robustness, redundancy and reparability targeting on the rapidity of functionality restoration after suffering extreme actions long-term durability deterioration. It stipulates lower probability reaching ultimate limit state or strength state, which have been only partly involved in codes around world. In AASHT...

The current research work summarizes some previous works on horizontally curved beams. Because of curvature, torsional effects in the analysis and design should be included. Diameter ring beam, number supports, beam width, compressive strength concrete, bearing plate width. Which can summarized from studies is that increasing diameter by about 25-75% decreases capacity load 14-36%, while suppor...

We present the i-ConeTM: a new projection-based panoramic display system for virtual environments. The i-ConeTM uses conical screen geometry, resulting in optimized projector placement to create an extended workspace for standing participants in a front projection curved screen display with a very large continuous field of view. Improved acoustical properties of the conical screen geometry enab...

An experimental apparatus to study the breaking process of axisymmetric liquid bridges has been developed, and the breaking sequences of a large number of liquid bridge configurations at minimum-volume stability limit have been analyzed. Experimental results show that very close to the breaking moment the neck radius of the liquid bridge varies as t, where t is the time to breakage, irrespectiv...

Introduction: The aim of this study was to evaluate the effect of bridge orientation in casting machine on castability and quality of base metal castings. Methods: Three groups of patterns with different direction and lengths in casting machine were casted and then studied qualitatively and quantitatively using mean and standard deviation in table of frequency. Results: Larger nodules and poros...
