MCR is planned to implement in the recently founded Virtual Research Laboratory (VRL). VRL is based on own platform in the 3DEXPERIENCE cloud organized platform at the Doctoral School of Applied Informatics and Applied Mathematics, Óbuda University. This cloud is operated by the Dassault Systémes S. A. In this paper, outline of scenario and former research and objectives are followed by an introduction of improved model mediated approach to MCR. Following this, role and consistent structure of contexts as key issues of model integrated research project and research specific role configuration for project participants are discussed. Finally, implementation issues are discussed in case of cloud platform.","PeriodicalId":321907,"journal":{"name":"2021 IEEE 15th International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"155 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127859006","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 this paper, we survey three different types of persons (instructors, students, and developers) to find out how often do those who write code struggle with architectural issues and how are those issues impacting their work. Our focus was on mobile projects, but to have a comprehensive overview, we have also questioned students – who might become mobile developers, to see if they understand the importance of architecture in their projects. We were also interested in instructors and their experience with the students on whether or not they lack architectural knowledge. Our research has found that all the questioned developers struggle with architectural issues in their projects, over 60% of the students had to re-write a project due to architectural issues, and over 94% of the questioned instructors stated that students have architectural issues in the projects they develop. The vast majority of the participants to the survey (100% of instructors, 100% of students, and 90% of developers) agreed that a tool that could validate the software architecture would help them.","PeriodicalId":321907,"journal":{"name":"2021 IEEE 15th International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128461505","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}

This task only in the case of quadratic cost functions can be solved without numerical iteration. The ambiguity of the possible solutions can be utilized by “adding” certain elements of the null space of the Jacobian to this solution. If the cost function has more complex structure the more general numerical procedure of Lagrange’s Reduced Gradient Algorithm can be applied. Recently it was found that this procedure seriously can be accelerated if the computation of the Lagrange multipliers belonging to the individual constraint equations becomes unnecessary. In this case a single vector must be reduced with the components of another one. In the present paper this method is directly applied for the efficient solution of the inverse kinematic task of redundant robot arms. The method is exemplified in designing a particular kinematic structure for a robot arm for specified use.","PeriodicalId":321907,"journal":{"name":"2021 IEEE 15th International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114319282","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}

Redundancy is often needed to make the arm “dexterous”. In general numerical techniques have to be applied. A typical approach is finding the “differential solution” by formulating the Jacobian of the problem in the first step, and using some generalized inverse that selects a definite solution of the ambiguous set of the possible ones. Each of these solutions suffers from huge joint coordinate time-derivatives in the vicinity of the kinematic singularities that are evaded by “deforming” the original task. A quasi-differential approach was recently elaborated that, though calculates the Jacobian, instead “inverting” it, applies a fixed point iteration that automatically evades the singularities. However, its solution depends on the eigenvalues of the Jacobian, and it was found not “flexible enough” for all practical purposes. The Moore-Penrose solution can be generalized as an optimization task under constraints for quite complex cost functions. The hard constraint in this approach forces the exact solution of the inverse kinematic task when it is possible. Due to it the intent of “minimizing the costs” is “overridden” in the vicinity of the singularities. In the present paper, based on the formal structure of the Receding Horizon Controllers, an alternative solution is suggested that allows flexibility for relaxing the costs and the “hard constraints”, too. Its computational complexity to some extent is reduced via evading the technique of gradient reduction. Simulation results are presented for a 7 DoF robot arm.","PeriodicalId":321907,"journal":{"name":"2021 IEEE 15th International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123684616","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}
