Study of Hole Flanging Process in Sheet Metal: A Review
Abstract: Hole-flanging is a common sheet forming process in which a flat circular sheet with a small homocentric pre-cut hole is forced locally with a punch around a die to produce a smooth rounded lip or flanged neck. The flanged hole is used for assembly with other components or other purpose. It produces a component with higher strength. This process is often used in the industry. In this paper hole flanging …

Experimental Investigation of Self-Compacting Concrete Using Coir Fiber
Abstract: Concrete is the construction material widely used throughout the world. Construction materials used in the industry should be friendly with the environment during their usage. Self-compacting concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. The hardened concrete is dense, homogenous …

Morphological and Dielectric Relaxation Responses of Polymer Stabilized Ferroelectric Liquid Crystal Composite Films
Abstract: Polymer-stabilized ferroelectric liquid crystal (GH-PSFLC) composite films have been prepared by polymerization-induced phase separation (PIPS) process as a function of polymer concentration. Epoxy polymer was homogeneously dispersed into FLC host matrix to create fibril network in the composite films. Twisted fibril-like network was observed through polarizing optical microscope through transmission mode. Dielectric relaxation spectroscopy of these composites shows that real part of permittivity decreases with polymer concentration. Goldstone relaxation mode …

Effect of Water Table Position on the Stability of Tunnel
Abstract: Tunnel is an underground structure used to convey the traffic. Construction of a tunnel in rock is a difficult task. In instances where tunnels are situated at shallow depths, the stability of the tunnel and its lining is notably affected by the adjacent surcharge loadings resulting from new building constructions or excessive loads on the ground surface. Stability of the tunnel crest also depends on the position of the water …

Simple Gain Model of Group III-V Semiconductor-based Laser Diode
Abstract: In these days, a layer of low bandgap material is sandwiched between two high bandgap layers.Most commonly-used pair of materials is gallium arsenide (GaAs) with aluminium galliumarsenide (AlGaAs) and Indium Phosphide (InP) with Indium gallium arsenide phosphide(InGaAsP) laser. A heterostructure is the junctions between different bandgap materials. Here,two such junctions are present, hence it is called the name "double heterostructure laser" orDH laser. The kind of laser diode may be …

Stable control of the motion of gas bubbles dissolved in a vibrating fluid in microgravity conditions
Abstract: Previous theoretical and experimental studies of the effect of vibration on gas bubbles, dissolved in a fluid, permitted to establish the localization and stable position of a “swarm” of gas bubbles at a certain level of fluid in the vessel corresponding to a certain frequency and vibration acceleration, aswell as to the volume of a swarm of gas bubbles. The control of a “swarm“ of gas bubbles in a fluid …

Mechanism of Intensive Gas and Fluid Mixture in the Process of Vibroturbulization and Its Technological Applications
Abstract: Previously conducted experimental studies have established that in a certain narrow frequency range and upon reaching a certain value of the amplitude of water oscillations in a sealed vessel with above-water air shell, subjected to vertical vibration, a resonant phenomenon occurs, called “vibroturbulization”, leading to intensive mixing of media of different density. The studies carried out were purely experimental in nature and could not reveal the physicochemical mechanism of occurrence, …

Stress Analysis and Deflection of Longitudinal Beam and Validate by using ANSYS
Abstract: This study investigates the deflection and stress distribution in a long, slender longitudinal beam of uniform rectangular cross section made of linear elastic material properties that are homogeneous and isotropic. The deflection of a longitudinal beam is essentially a three dimensional problem. An elastic stretching in one direction is accompanied by a compression in perpendicular directions. The beam is modeled under the action of three different loading conditions: vertical concentrated …

Influence of Blending Technique on Surface Free Energy of Modified Asphalt Cement
Abstract: AbstractThe processing technique of modified asphalt cement in the laboratory is adopted by heating the asphalt cement in an oven to the required mixing temperature; then the additive is added and mixed for a target mixing time. It was felt that such technique allows more volatiles to evaporate and required high mixing temperature. In this work, asphalt cement of 44 penetration grade was gained from Dora refinery, south west of …

Comparison of Ultra Wide Band Indoor Multipath IEEE 802.15.3 Channel Model
Abstract: ABSTRACT A very large bandwidth of frequency (3.1–10.6 GHz) has been allocated to UWB systems. A single-band UWB signal propagates differently in the lower and upper bands of the spectrum due to the size of its bandwidth. The lower part of the signal can be obstructed more easily and the man-made interferences are not homogeneously distributed over the whole spectrum. The first experimental results obtained for a UWB channel show …

Concept of Ojas with Relevancy of Physiological Properties
Abstract: In the human body, metabolic activity is performed by Tridosha (functional entity and vitiating substances), Sapta Dhatus (seven tissue levels) and Malas (waste products). In addition to this, Ojas is considered as Dhatu & the essence of all Dhatus, which is present in every compartment of the body. Its quality is homologous to Kapha (lubricating and protective substance). Strength and body protecting phenomenon are governed by certain substances. It lies …

Prevention of Varicose Veins
Abstract: Varicose veins are abnormal, dilated blood vessels caused by weakening in the vessel wall. Such conditions that increase pressure on the leg veins such as overweight, lack of exercises, hormonal fluctuations during pregnancy and menopause, smoking; constipation or people who have prolonged standing or sedentary position or repeated heavy lifting make veins of legs very weak and develop into varicose veins. Researchers report that a mild care of varicose veins …
