The primary task of a robotic manipulator is to move its end-effector from an initial position and orientation to a predefined goal position and orientation. This research considers motion planning with obstacle avoidance for planar redundant robots with constrained joint space. It analyses their kinematics and defines the different types of inverse kinematics solutions. On the basis of those types of solutions in the robot workspace are defined zones corresponding to each solution type. The research proposes a numerical approach for finding the specific points at which the robot can change its solution type. Those points are of interest when the robot has to execute a motion which passes through different zones of the workspace which are not intersecting. In such cases the robot is required to pass through some of those points in order to be able to change the solution type and to execute the desired motion. The approach applicability is validated through conducted experiments.","PeriodicalId":115575,"journal":{"name":"Proceedings of the 22nd International Conference on Computer Systems and Technologies","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124110016","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}

An adapted instrument was translated and revised multiple times before administering the final version of the questionnaire to students. The findings of the research have revealed that students have sufficient digital facilities and they are familiar with using technologies for their language learning. Furthermore, students have achieved an average level of digital skill, and they are most proficient in using social networking services in comparison with other applications. Concerning the frequency of using digital tools, students reported that they do not often utilize digital applications in their language learning. Among applications, students more often use social media than other tools. Besides, the study also explored that there are correlations among digital skill, the frequency of using technology and the ICT facilities and ICT familiarity. It is suggested that there is a necessity in curriculum or teaching methodology changes to create opportunities for students to enhance their digital skills in their language learning in particular and in education in general as they are the digital ‘natives’ of the community.","PeriodicalId":115575,"journal":{"name":"Proceedings of the 22nd International Conference on Computer Systems and Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128035231","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}

A novel graph-based approach for the representation of software samples over the depiction of the structural evolution over time, the so-called Temporal Graphs, is discussed, and a method for measuring graph similarity among specific Regions of such graphs is proposed, the so-called Regional Matching. The partitioning of the Temporal Graphs that depicts their structural evolution over time is defined by specific time-slots, while the quantitative characteristics that depict the commonalities appeared over the weights of the vertices are measured by a similarity metric in order to conduct the malware detection and classification procedures. Finally, we evaluate the detection and classification ability of our proposed graph-based framework performing an experimental study over the achieved results utilizing a set of known malicious samples that are indexed into malware families.","PeriodicalId":115575,"journal":{"name":"Proceedings of the 22nd International Conference on Computer Systems and Technologies","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128837630","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 approach is not the best for many learners, especially for those with various difficulties or interests. Strategies for personalization and adaptation can increase the tutoring quality and ensure efficient learning for groups of learners with different needs, goals, or interests. Intelligent technologies can enable the personalization of the learning process. However, no one system can contain all the knowledge needed for all learners, so interoperability between e-learning systems is of greater importance. Standards are needed for ensuring interoperability, but they are not sufficient. This paper first analyzes and classifies sources for learning on the Internet. The findings help to develop a knowledge model needed for a personalized recommendation of web-based sources, complementary to the learning content that a well-organized intelligent educational system can propose to learners. Having in mind specifics of the ontologies needed for modeling the learning domain, a model of the ontological repository for storing ontologies that can be useful for building intelligent educational systems is suggested. We also discussed mapping problems between ontologies and modeling e-learning standards.","PeriodicalId":115575,"journal":{"name":"Proceedings of the 22nd International Conference on Computer Systems and Technologies","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126040872","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}
