One of the main scenarios for analyzing mechanical systems including the no holonomic constraints will be carried out by using Lagrangian formulation and its associated “Lagrange multipliers”. Most research on movable manipulators are limited to robots with only rotating joints. The dynamic equations of robots with rotational and prismatic movement is a very important subject with many applications. The combination of this system with a movable base will bring capability of operating in a wider area than a fixed base manipulator. The moving ability added to the agility of the manipulator, is requirement of many application such as; space explores, rescue operations, operation in hazardous locations, agriculture, and so on. Eliminating these variables from the obtained equations is a time-consuming and cumbersome task. To prevent computing the Lagrange multipliers associated with the nonholonomic constraints; Gibbs-Appell formulation shall be implemented. To automatically derive the motion equations and upgrade the computational efficiency, a recursive algorithm has been derived in the simulation of the system. In the concept of this algorithm, all the mathematical scheme is carried out by only 3 × 3 and 3 × 1 matrices. In the last section, computational modeling for a chain of the manipulator with 3 links and primary joints in each arm is performed to show the aptitude of the proposed scheme in implementation of the motion equations and parametric analysis for complex systems at this level. One of the main purposes of this study is to develop rover technologies for interplanetary explorations.","PeriodicalId":90538,"journal":{"name":"International journal of advancements in computing technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74285957","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 microstructure of the UTPC-processed specimen showed the spheroidization of cementite observed in the depth region of 0.5-1 mm from the topmost surface. In addition, voids and cracks were not observed in the specimen bulk. The Charpy impact energy of UTPC had the highest value of 101 J because ductile layers were formed by UTPC processing. Stress relaxation behavior of various processed materials at a temperature of 500°C was investigated. Compressive residual stress of more than 100 MPa was retained after annealing both the WJC- and UTPC-processed specimens for 5 hours. After stress relaxation testing, cracks owing to thermal stress do not occur at the grain boundary in the UTPC material having a tenacious tough layer inside. Micro-forging (UTPC) is promising for high-temperature oxidation of low-alloy steel, Ti alloy, and Inconel. Moreover, low-temperature and low-pressure cavitation (LTPC) is applied to age hardening of aluminum alloy Al-Mg-Si (AC4CH).","PeriodicalId":90538,"journal":{"name":"International journal of advancements in computing technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86444111","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 central idea is to mainly determine the role of QoS on some applications. This paper includes a simple network which does not include quality of service and a complete network with some applications in which authentic parameters regarding the quality of service, are applied. Thus, it has been concluded there is a great impact of QoS in a network.
