Ultrasonic Treatment to Molten FEM©™ Aluminum Alloy and Effects of Ultrasound...
Ultrasonic Treatment to Molten FEM©™ Aluminum Alloy and Effects of Ultrasound...editor1knowledgecuddle
Today, in the industry of aluminum, the D. C. casting of billets and slabs is playing the major role. The producers of these slabs and billets are many. The end users of the product are OEMs. The degassing technology for producing these aluminum slabs and billets is provided by very few. There are two types of degassing methods currently in use. One of these, vacuum degassing, is used primarily in the steel industry and thus not generally used in the aluminum industry. The second method, generally employed in the aluminum industry, is rotary degassing, which uses finely dispersed argon, chlorine, fluorine to remove dissolved hydrogen and various salts from melt. The challenges associated with producing aluminum are reducing porosity due to hydrogen precipitation during casting through degassing processes; which generates detrimental effects on mechanical properties of alloy castings and removing impurities like; the Ca, Mg salts etc. from the molten metal. Looking at the degassing systems provided by these players, are going to be obsolete as the environment norms will become stricter in the next decade, because of the use of Fluorine and Chlorine for removing the Ca, Mg, etc. impurities from the molten metal as the ozone layer is getting depleted and process becomes more cumbersome and hazardous. So, the innovation in the technology is needed; which leads research interest on development of the ultrasonic degassing as a better option. During this research authors would be using ultrasonic technology over existing technology to compare the results of conventional degasser units available in the market such as LARSTM, SNIFTM, STASTM - ACDTM, AlpurTM, MDUTM etc., and would be finding out the better operating parameters of ultrasonic equipment for the process for replacement of Fluorine and Chlorine based old technology with Ultrasonic Technology. This research paper should underpin improvement in the process and hence improved hardness of material by elimination of the fluorine and chlorine usage by replacing it with ultrasonic technology with suitable mechanical design, metallurgical criteria and thermal analysis consideration. During the entire research and development authors had carried out various operations like Research on thermal and metallurgical behavior of the molten metal and alloys, Comparison of results achieved using ultrasonic technique over existing technique, Formulation of conclusion; making ultrasonic technique a proven technology, and Identifying the further scope of research and development. With the experiments carried out, authors found significant improvement in hardness of the material produced by ultrasonic degassing as compared with the hardness of material produced by conventional degassing.A STUDY ON THE INFLUENCE OF JOB STRESS IN ORGANISATIONAL FACTORS
Today, occupational accidents are considered among the potential threats because of their serious humanitarian, economic, social, and environmental consequences. Occupational accidents and injuries are the third cause of mortality in world and the second one in Iran. In addition, the economic and environmental damages of occupational accidents are catastrophic too.According to International Labor Organization (ILO) report in 1999 the average estimated fatal occupational accident rate was 140/100 000 workers and the number of fatal accidents was 335000. Though the registered number of accidents in Iran cannot be a faultless account of all the accidents happened, but in 2000, about 12000 work related accidents have been registered by the Department of Social Security. Calculations indicated that approximately 345000 fatal occupational accidents occurred in 1998 and that over 260 million occupational accidents causing at least 3 days absence happened in the same year. This work aims to study the relation of occupational stress of workers and the accidents in a rice milling industry. The data was collected using questionnaire. The questionnaire contained 30 questions to measure the perception s of the employees about the management practices. A five point likert scale was used. This was prepared based on review of related literature .The contents of this draft questionnaire were discussed with senior safety professional in the industry. Data was analyzed using IBM SPSS Statistics 20 software. Descriptive statistics and correlations of the studied variables were first analyzed. Confirmatory factor analysis was used to verify the reliability of the management practices. Regression analysis was conducted to test the goodness of fit of the various models. Keywords - industrial safety, occupational stress, accidents, factor analysis
A Basic Knowledge of Image Morphing
The term "morphing" is used to describe the combination of generalized image warping with a crossdissolve
between image elements. The term is derived from "image metamorphosis". Morphing is an image
processing technique typically used as an animation tool for the metamorphosis from one image to another. The
idea is to specify a warp that distorts the first image into the second. Its inverse will distort the second image into
the first..The morph process consists of warping two images so that they have the same "shape", and then cross
dissolving the resulting images. Cross-dissolving is the major problem as how to warp an image. In this paper I
have concentrated on one of the methodology of image morphing named “Mesh Warping”.
Keywords: Morphing, Warping, Cross-dissolve, Metamorphosis.
Missing Data in Research on Child Maltreatment
Implications of non-response and loss to follow up and some possible solutions.
