Injuries, accidents or even fatalities are often reported due to direct exposure of process hazards such as hazardous chemicals while working with the pilot plant. Even though the quantity of hazardous materials at the lab-scale pilot plant is small compared to real scale plant, but the impact of the hazards can be very high that may cause fatalities and properties damage. However, there is no structured technique reported that successfully manage process hazards in pilot plant. It is well known that the management of process hazards is a requirement in Occupational Safety and Health Administration (OSHA) Process Safety Management (PSM) CFR 1910.119(e) for process industries. PSM is recognized by industries as the best for prevention of major accidents in process plant, but they are still struggling to comply with the PSM standard due to lack of effective implementation technique. This paper presents a strategy on how researchers could manage the process hazards effectively at the same time could comply with OSHA PSM CFR 1910.119(e). A framework is developed based on OSHA PSM CFR 1910.119(e) as a guideline for easy implementation in the lab-scale plant. The application of this concept will assist by computer technology for efficiently collect, update, review and revalidate the process hazards' information. This method once implemented perhaps could reduce the injuries, fatalities and properties damage due to unsafe workplace.","PeriodicalId":6411,"journal":{"name":"2011 National Postgraduate Conference","volume":"2 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76702938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jha, Sultan Alimuddin, Shafauddin","doi":"10.1109/NATPC.2011.6136465","DOIUrl":"https://doi.org/10.1109/NATPC.2011.6136465","url":null,"abstract":"Enormous percentage of total original oil in place lies in the fractured reservoirs. There dual permeability plays an important role to enhance the oil production rate which is governed by the large surface area provided by fractures so that fluids can move easily from low permeability zone matrix to high permeability channeled network zone. Convective current is setup in reservoir due to density inversion. This creates a favorable condition of mass transfer by diffusion. Due to high geo thermal gradient and convective motion of fluids in geothermal reservoir, diffusion can lead to the elevation or depression of bubble point pressure. When reservoir pressure gets drops it leads to evolution of gas from matrix zone which eventually gets transferred to gas cap. This leads to depression of Bubble Point. Now, when reservoir pressure increases it leads to transportation of gas from gas cap to matrix zone. This leads to elevation of Bubble point. In this paper a quantitative analysis of diffusion process for an arbitrary inclined fracture [1] by the help of FICK'S law of diffusion and continuity equation of diffusion is done. Through this analysis we obtain a final differential equation by applying material balance on the dissolved gas in the fracture. Lastly effective diffusion coefficient of the fractured media is quantitatively analyzed. Thus, correct analysis of reservoir in terms of microscopic and macroscopic sweep efficiency is done by the inclusion of this diffusion process. Hence, a better model to simulate the fractured reservoir can be made by selecting appropriate boundary conditions for the final differential equation obtained and proposed in this paper. Also we can understand the actual solution gas drive mechanism in the fractured reservoirs correctly. Negligible works have been done on the Mass Transfer analysis in the inclined fractured reservoir theoretically or experimentally and thus here an effective mathematical model of the mass transfer in an arbitrary inclined fracture has been formulated and presented for regulators of hydrocarbon industry for high outcome from a field.","PeriodicalId":6411,"journal":{"name":"2011 National Postgraduate Conference","volume":"34 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79054294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In hot mixture asphalt (HMA), gradation helps determine almost every important property. The gradation that produces maximum particle interlock, maximum packing density, maximum strength, desirable air voids and voids in mineral aggregate and lowest permeability is highly desirable for bituminous mixture. Coarse aggregate that have good particle packing can bring the particles closer and can decrease the space between them, and this consequently gives the interlock necessary to increase the strength for better resist to distresses. In this project, different sizes of coarse aggregate are studied to identify their corresponding optimal proportion in bituminous mixture for better density through the packing test. According to the maximum density observed, the optimum proportion for the mix is found to be 14.4% for coarse aggregate retain on 20mm, 21.6% for coarse aggregate retain on 14mm, 24% for coarse aggregate retain on 10mm, and 40% for coarse aggregate retain on 5mm.","PeriodicalId":6411,"journal":{"name":"2011 National Postgraduate Conference","volume":"10 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81649464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these issues, researchers in recent years have proposed computational imaging methods for aiding in the acne diagnosis. This paper proposes an algorithm to identify acne lesions, scars and normal skin features from photographs taken by Digital Single-Lens Reflex (DSLR) cameras. The images are converted from RGB to CIELAB color space, thresholded to three clusters and segmented using minimum Euclidean distance. The segmentation results from randomly selected images show sensitivity and specificity of greater than 80%.","PeriodicalId":6411,"journal":{"name":"2011 National Postgraduate Conference","volume":"1 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86043097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Incident Report-Based Safety Knowledge Transfer (IRSKT) model we advocated in this paper identifies the elements neccessary for social systems in academia to extract, disseminate and use new safety knowledge emanating from incident reports. The purpose of the paper is to understand how developments in systems thinking and materiality of knowledge can influence understanding of safety knowledge transfer (SKT); and to propose a new systems-based safety knowledge transfer model founded on incident reports. The paper is a review of the literature on safety knowledge transfer, materiality of knowledge and systems thinking; leading to the proposal of a new SKT paradigm. The paper shows that the IRSKT model is well suited to analyzing safety knowledge transfer in both complex and small-scale systems in academia. The paper argues that in academic institutions where safety of students and researchers is important, the ability to extract knowledge from incidents reports — which is an assesible and ready estimate of safety situations in organizations - is vital for establishing safe laboratories and learning environments. The capacity for effective exchange and utilization of safety information inherent in incident reports by employees, equipment manufacturers, professional bodies and government agencies as reflected in IRSKT will inform the decisions to build in safety in machinery, better safety rules, effective safety campaigns and enhance safety conscious behaviours in academia.","PeriodicalId":6411,"journal":{"name":"2011 National Postgraduate Conference","volume":"12 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86230268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
