While studying ergonomic considerations for dentists, it is observed that they suffer from musculoskeletal disorders (back pain) due to repetitive and awkward or stressful motions during their operation. This paper involves the literature survey on ergonomic design of dentist chair and associated studies in dentistry. There is scope for implementing the modifications leading to the design of a new support arm to the dentist chair. In the literature it was found that static and dynamic analysis could be used to find stress (compressive force on lumbar disc) in the human body by Rapid Upper Limb Assessment (RULA) risk assessment technique for different loading conditions. Thus it was observed that there is a need for designing a new support arm to reduce musculoskeletal disorder problems. This paper will help the dental professionals to adopt correct human postures, which will enhance their working capacity to work in a pain — free environment to deliver quality dental care to their patients by providing support to forward-leaning postures.","PeriodicalId":123922,"journal":{"name":"Frontiers in Automobile and Mechanical Engineering -2010","volume":"327 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133985033","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 low heat rejection concept is based on suppressing this heat rejection to the coolant and recovering the energy in the form of useful work. The purpose of this project is to increase the performance of the engine and improved the fuel economy resulting from coating those using partially stabilized zirconia (PSZ) thermal barrier coating for the performance in the diesel engine application. PSZ over the combustion chamber increases the temperature over the inside the combustion chamber and reduces the heat rejection to the atmosphere. Also an experimental investigation performed using a thermally insulated single cylinder direct injection water cooled diesel engine to evaluate the effect of coating on the cylinder head, piston top surface and the valve seats using PSZ to study the heat release, performance and emission characteristics. Studies are conducted for the engine with insulated head and piston and are compared with the base line engine. Based on the experimental studies it is concluded that a thermally insulated engine reduces the fuel consumption, improves the fuel efficiency. Also the emissions of HC and CO are reduced to a great extent while the emissions of NOX are increased due to higher combustion temperature. Various method of reducing NOX emissions will be adopted. Such as retarding the fuel injection timing, lowering the intake temperature, lower compression ratio. Thus, the LHR engine was tested for two different injection timings at Crank angle before top dead centre (BTDC), with the same engine Speeds and load conditions. The results showed that the BSFC and NOx emissions were reduced respectively by retarding the Injection timing.","PeriodicalId":123922,"journal":{"name":"Frontiers in Automobile and Mechanical Engineering -2010","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121462825","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}

Particularly it focuses on the suggestion to curb the vehicular pollution by the use of biodiesel. The pollution loads have been calculated and compared by considering usage of the biodiesel in place of conventional diesel fuel in buses. For the purpose of this study, the three depots of the NE-Karnataka Road Transport Corporation, Gulbarga's were considered. The three depots consists of 86+101+117=304 buses. These buses run on diesel fuel and are responsible for largest amount of lead emissions and various other pollutants. The pollution loads were calculated on the basis of information collected from the Central Pollution Control Board (CPCB), Environment Protection Agency and previous studies carried out in this regard by various important agencies. The use of Biodiesel shows tremendous reduction in various pollutants. By the use of B20 Bio-diesel we can reduce total unburnt hydrocarbons to 20%, Carbon monoxide to 12%, PM10 and PM25 to 12%, NOx +2 or −2%, SO2 to 20%. By the use of B100 Bio-diesel we can reduce total unburnt hydrocarbons to 67%, Carbon monoxide to 48%, PM10 and PM25 to 47%, NOx +10 or −2%, SO2 to 100%.","PeriodicalId":123922,"journal":{"name":"Frontiers in Automobile and Mechanical Engineering -2010","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127176671","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}

Among the various processing route, flex assisted synthesis is a highly potential and low cost method to produce in-situ composites. In-situ aluminum matrix composite has superior performance than the ex-situ composite because of the chemically dispersed reinforcements. In the present work, flex assisted synthesis process is to produce AA2219 — TiB2/ZrB2 in-situ aluminum matrix composite with the different reinforcement ratio. EDAX, SEM and micro hardness analysis was carried out to confirm the presence reinforcements. EDAX analysis confirms the presence of reinforcement and element percentage of the composites. Microstructure analysis shows the distribution of in-situ reinforcements and the CuAl2 formation in the grain boundary regions of the matrix.

For that reason the surface coating techniques become popular. The detonation gun (d-gun) spraying is one of the most advanced thermal spray variants for depositing high quality wear resistant coatings. Of all the ceramic materials that can be D-gun sprayed, alumina (Al2O3) is the most widely established and these coatings have already gained industrial acceptance for diverse applications. The present study deals with a statistical design of experimental study of the D-gun spraying of Al2O3 powder. Coating experiments were conducted, using a Taguchi L4 design parametric study, to optimize the D-gun spray process parameters. Three selected important spraying parameters were considered in their upper and lower levels of the predefined range according to the test matrix, in order to display the range of processing conditions and their effect on the coating quality. Image analysis and micro-hardness testing was used for characterization. Coating qualities are discussed with respect to surface hardness and microstructure. The attributes of the coatings are correlated with the changes in operating parameters and their relative importance and contribution ratios to overall variance are calculated","PeriodicalId":123922,"journal":{"name":"Frontiers in Automobile and Mechanical Engineering -2010","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128541966","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}
