They can be overlapped to various other manufacturing and storage\u0000system and controlled through an advanced computer control system. Flexible Manufacturing systems (FMS) are\u0000compatible for concurrent manufacturing of a good sort of parts in low quantity. The Flexible Manufacturing systems\u0000elements can operate in a non parallel manner and the scheduling problems are harder. The use of AGVs is increasing\u0000day by day for the fabric movement in production lines of flexible manufacturing plants. The purpose is to extend\u0000efficiency in material transfer and increase manufacturing. Though the hardware of Automated Guided Vehicle has\u0000made remarkable enhancement in the field but the software control of the speed still lacks in many applications. The\u0000order of scheduling of operations on machine centers as well as the scheduling of Automated Guided Vehicles are\u0000important factors contributing to the overall efficiency of flexible manufacturing system (FMS). In this work,\u0000scheduling of job is done for a particular type of flexible manufacturing system (FMS) environment by using the\u0000technique of optimization called the genetic algorithm (GA). A code was developed to seek out the optimal solution\u0000and generate random values in Ms-Excel. When a chromosome is input, the GA works upon it and produces same\u0000number of offspring’s. The number of iterations takes place until the optimum solution is obtained. Here we've\u0000worked upon eight problems, with different no. of machines and no. of jobs. The input parameters used are time\u0000period matrix and time interval matrix with the amount of machines and number of jobs. The results obtained are\u0000very quite close to the results obtained by other techniques and by other scholars.","PeriodicalId":192480,"journal":{"name":"International Journal of Current Engineering and Technology","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126176383","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}

It is blended with the cement for\u0000manufacturing concrete. It reduces the environmental impact of the cement industry. Blending of cement with\u0000supplementary cementitious materials like fly ash and rice husk ash makes concrete more durable. This paper studies\u0000effect of a partial replacement of cement with various ratios of rice husk ash (RHA) on physical and mechanical\u0000properties of concrete. Three mixtures were prepared with proportions of 4, 8, and 16% RHA by weight of cement in\u0000addition to 15% fly ash (FA) by weight of cement to be compared with a reference mixture with 100% Portland\u0000cement. Compressive strength test, tensile strength test, flexural strength test and rate of water absorption test were\u0000performed at different ages of curing. Test results have reflected that the compressive strength, tensile strength and\u0000flexural strength achieved with 16% replacement of cement with RHA maximum increase. Compressive strength\u0000increased with 16% RHA by 12.5% at 56 days age compared to compressive strength of control mix.

It comprises almost sixty per cent of the\u0000world’s energy consumption which demands further extraction of remaining oil.

Mobility control is very important; therefore, the alkaline flooding coupled with polymer\u0000flooding is good for controlling mobility. To provide a critical review of Alkaline-Polymer flooding, this paper presents\u0000a comprehensive study. This paper covers the following content: Interaction of Alkali-Polymer, technical screening\u0000criteria, simulation work and summary of field projects. Analysis was carried out to compare the different scenarios of\u0000polymer, alkaline, and alkaline 8 polymer of injected slugs and their performance in terms of corresponding oil\u0000recoveries.

This has been accomplished to define the dynamic performance of LIM when considering the end\u0000effects, which can be directly applicable for vector control and drive implementations. The first model separates the\u0000primary and secondary(linor) d-q axis currents into two components, one part is free from end effects while the other\u0000is based on end effects.

Billions of dollars are\u0000being spent by oil and gas industries to set up the infrastructures of smart field. Managing these fields involves\u0000combined methods and knowledge for unmanned and independent handling of these field an enough number of\u0000synchronized data is gathered and monitored from wells for smooth and uninterrupted operation. Among all forms of\u0000artificial lift, the most common used is automatic gas lift, which is mostly used for offshore wells. The reason for its\u0000simplicity and relative use is its downhole flexibility, simplicity, reliability, and capability to operate over a widespread\u0000range of flow rates with restricted well head space. Implying the Automatic Gas lift (AGL) technique can cut the\u0000operational cost and increases the “Net Present Value” (NPV) by maximizing recovery from a field.\u0000In this study, GAP models were being made for DN horizontal, DI Vertical, Non-Contagious (NC), and AGL. The models\u0000made were used to predict cumulative oil production, gas production, water production, and pressure drop. After all\u0000the predictions were made comparative study was done in order to understand the trends. The results demonstrate\u0000substantial increase in oil recovery using Auto Gas Lift in the field through vertical wells 1,2 and 3 which otherwise is\u0000quite low in do-nothing case. Moreover, it has been observed that Auto Gas Lift provides higher recovery compared to\u0000vertical wells.
