Abstract—This paper deals with the analytical investigation of thermal and thermohydraulic performance of double flow solar air heaters with corrugated and flat plate absorber. A mathematical model of double flow solar air heater has been presented, and a computer program in C++ language is developed to estimate the outlet temperature of air for the evaluation of thermal and thermohydraulic eff...

S U M M A R Y We use numerical models to investigate the dynamics of two interacting slabs with parallel trenches. Cases considered are: a single slab reference, outward dipping slabs (out-dip), inward dipping slabs (in-dip) and slabs dipping in the same direction (same-dip). Where trenches converge over time (same-dip and out-dip systems), large positive dynamic pressures in the asthenosphere ...

In this study, fatigue test and crack propagation analysis of welded joints in ships and offshore structures were performed. The test models have two types of welded joints, T-joint and double plate. Test data is presented in S-N curves obtained by the Hot Spot Stress (HSS) approach. The S-N data for each length of crack were appraised to define the fatigue life of crack initiation and propagat...

This paper studies the dynamic response of rectangular reinforced concrete plates on an elastic foundation by state space method. The system differential equations vibration plate is developed using Hamilton's principle. With a single-link plate, displacements are represented through double trigonometric series. Use method to find vibrational responses. calculation examples performed calculate ...

This article investigates the static behavior of functionally graded plate under mechanical loads by using a new quasi 3D model. The theory is designated as fifth-order shear and normal deformation theory (FOSNDT). Properties of functionally graded material are graded across the transverse direction by using the rule of mixture i.e. power-law. The effect of thickness stretching is considered to...

OBJECTIVE The purpose of this study was to compare the stability and feasibility of four fixation constructs in a posterior column acetabular fracture: one reconstruction plate, one reconstruction plate and lag screw, two reconstruction plates, and a W-shaped acetabular angular plate. METHODS Twenty embalmed cadaveric pelvises with a posterior column acetabular fractures were allocated to one...

Notch deformation behaviour under monotonic and cyclic loading conditions was investigated using circumferentially notched round bar and double-notched flat plate geometries, each with two different notch concentration factors. Notch strains for the double-notched plate geometry were measured with the use of miniature strain gauges bonded to specimens made of a vanadium-based microalloyed steel...

Automatic Number Plate Recognition (ANPR) is a mass surveillance system that captures the image of vehicles and recognizes their license number. ANPR can be assisted in the revealing of stolen vehicles. The recognition of stolen vehicles can be done in an efficient manner by using the ANPR systems located in the highways. ANPR systems are very useful to the law enforcement agencies as the need ...
