A physical model for palaeosecular variation

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Physical Determination of Permeability Variation With Porosity For Composite Performs

Abstract: This paper presents the results of experimental determination of fiber bed permeability variation with porosity. Flow measurement experiments were designed to measure fiber mat permeability for fiber beds with various fiber volume fractions. Woven fiberglass, chopped fiberglass, and carbon fiber mats were used as reinforcements. The effects of reinforcement type and porosity on fiber ...

A model for tracking temperature variation in cold and hot metal working conditions during machining operations

This paper presents a mathematical model that could assist in measuring, monitoring and controlling tem-perature variation in cold and ‘red-hot’ metal working conditions of machining. A numerical analysis tech-nique of the temperature distribution, based on the theory of complex applied potential, was carried out using the principles of relationship analysis between the paths of heat supply in ...

Investigation of Submerged Vanes Array for Sediment Control at Intake Using a Physical Model

A Physical Rehabilitation Model for Disabled, Elderly and Injured in Emergency Situations (earthquake)

Objective and Backgrounds: Children, elderly and people with disabilities are mainly affected by damages in any accident or natural disasters. The people with disabilities are neglected in every phase of crisis management evidently. This negligence is more significant in emergencies, specially the need for rehabilitation of these people during 72 hours after earthquake. Method: In this paper, ...
