the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Automated System for Magnetic Particle Inspection of Railway Wheels
This paper presents a new developed automated system used for flaw detection and classification on railway wheels. The described system uses the principle of non-destructive method based magnetic particle inspection. Our proposed and finally constructed automated system is used in industrial applications where non-destructive testing of railway wheels is desired. As a part of testing line, it i...
متن کاملStrength calculation of rewards
Persuasive negotiation involves negotiating using rhetorical arguments (such as threats, rewards, and appeals), which act as persuasive elements that aim to force or convince an opponent to accept a given proposal. In the case of rewards, these have a positive nature as they use the argument that something positive will happen to the opponent if he accepts to do the requirement sent by the prop...
متن کاملLife Estimation in the Railway Wheels Under the Influence of Residual Stress Field
This paper presents the prediction of fatigue life and crack propagation in the railway wheel due to the stress field caused by mechanical loads and press fitting process of a railway wheel. A 3-D nonlinear stress analysis model has been applied to estimate stress fields of the railway wheel in press fitting process. Finite element analysis model is presented applying the elastic–plastic fin...
متن کاملCalculation of lateral velocity estimation and error discrimination for railway wheelset to avoid sliding
Lateral velocity has very backbone position in the railway vehicle wheelset dynamics as it usually becomes cause of derailment by sliding due to insufficient adhesion ratio. This impropriate balance is pretext owing to contamination and weather procures the disturbances. This perturbation makes hindrances in proper running of wheelset on track. To analyze the noise, Kalman filter is used based ...
