In the face of the climate crisis, petroleum dependence, and volatile gasoline prices, it is imperative to explore possible opportunities in unconventional alternative-fuel vehicles. In this due course Compressed Air Vehicles (CAV) is a thrust area of research. CAV utilizes high pressure energy of air from compressed form which is converted into mechanical output. For the same Compressed air is stored in a cylinder and released by a nozzle connected through the piping. Compressed air passing through nozzle strikes the blade with a very high velocity, resulting in the rotation of prime mover. To produce a high torque and to reduce the rpm, this prime mover is coupled with gear train which is further connected with the axle. So that rotational energy of prime mover is converted into mechanical output easily and efficiently i.e. the motion of CAV. Based this protocol a prototype compressed air vehicle was designed and developed. The efficiency of the prototype model under the different condition of load and speed in rpm was studied. Results show that although the CAV is a bold, unconventional solution for today’s transportation challenges, it is ultimately not workable, and compares poorly with gasoline and electric vehicles in all environmental and economic metrics.","PeriodicalId":234213,"journal":{"name":"CSVTU Research Journal on Engineering and Technology","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121081541","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}

These models are multi-layer perceptron (MLP) and generalized regression neural network (GRNN). Total 96 data were used in neural model. The neural model developed with six input parameters: mass flow rate, wind speed, ambient temperature, inlet air temperature, air mean temperature and solar intensity, thermal efficiency is used as output variable. In MLP model, LM with 13 neurons was optimal model and in case of GRNN model, maximum accuracy in prediction has been obtained at spread value- 0.8.  The comparative analysis shows that the GRNN is the best model as compared to MLP due to less error and highest value of R2. These results show that the GRNN model is appropriate model for predicting the thermal performance SAH.","PeriodicalId":234213,"journal":{"name":"CSVTU Research Journal on Engineering and Technology","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121193177","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 VLSI circuit design, power dissipation and leakage present are the critical design structures as they show anvital role in act of the battery. Power management of chip is the major challenge. Leakage power is a crucial parameter as the technology is shrinking (180 nanometer, 90 nanometer, 45 nanometer).The leakage current is increasing very fast so numerous technique has been proposed for leakage reduction in CMOS digital integrated circuit. This review paper demonstrates the various reduction showcase for CMOS integrated circuited.","PeriodicalId":234213,"journal":{"name":"CSVTU Research Journal on Engineering and Technology","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127621619","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}
