Countless case-studies have identified weak points in the ever popular open-source system and sometimes, found solutions. Comparisons were made with other popular learning management systems (LMS), either commercial or free and open-source, with mixed results. These comparisons were usually employed as the tools for choosing one LMS over another, in the preliminary phase of adopting or developing a new e-learning platform. However, if the platform already exists, and has been functioning for a decent number of years, is it still necessary to test its usability? Considering that Moodle is currently on a bi-annual cycle for official releases and the online world is a very dynamic environment in need of constant adapting, the answer seems to be affirmative. Then, what are the main ways in which to test the usability of a learning platform (Moodle in particular), with its own characteristics which sets it apart from the general considerations of a web platform? Which of these methods are best suited for the different types of analyses we call “usability”? These are some of the questions that this paper tries to answer by analyzing the needs for usability testing and subsequently proposing a testing strategy for the “Campus Virtual” e-learning platform, the official online tool for managing the learning process in the Politehnica University Timisoara.","PeriodicalId":144551,"journal":{"name":"2015 IEEE 13th International Symposium on Intelligent Systems and Informatics (SISY)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127227980","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 problem can be handled by regularizing the task Jacobian, however this requires the knowledge of the regularization vector. A candidate for the regularization vector for an elbow manipulator is given, and it is proved that this candidate can be used in almost every configuration. The candidate is the linear velocity generator of the last joint, so the calculation of the regularization vector does not require high computational capacity. The smallest singular value of the regularized task Jacobian is further analyzed in different singular configurations.","PeriodicalId":144551,"journal":{"name":"2015 IEEE 13th International Symposium on Intelligent Systems and Informatics (SISY)","volume":"152 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127029626","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 have observed how to transform a pseudo-integral into another pseudo-integral that enables us to give the relationship between the pseudo-integral and other integrals based on monotone set functions such as the universal, Sugeno and Shilkret integrals. Also, using the transformed pseudo-integral we have obtained a monotone convergence theorem for the pseudo-integral. As a consequence of the monotone convergence theorem we get the Fatou's lemma for the pseudo-integral.","PeriodicalId":144551,"journal":{"name":"2015 IEEE 13th International Symposium on Intelligent Systems and Informatics (SISY)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114940796","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}

One of these capabilities is angiogenesis; tumor cells have to become able to force new vessel formation to ensure oxygen and nutrient supply. In the literature, there are several different growth models which aim to describe the growth characteristics. The model creation is a trade-off problem. On the one hand, the model has to be sufficiently complex to describe all the important processes which take part in the system; however, on the other hand, the model has to be sufficiently simple and manageable for real-life usability and - taking into account the applicability of biomedical control theory - for controller design. We discuss some relevant tumor growth models used in the literature showing their complexity and their modeling power.","PeriodicalId":144551,"journal":{"name":"2015 IEEE 13th International Symposium on Intelligent Systems and Informatics (SISY)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122943455","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 the geometry, kinematics and dynamics of the vehicle are modeled as a tree structured mechanical system using the modified Denavit-Hartenberg convention. Two type of techniques are considered to find the dynamic model: the mixed Newton-Euler formalism based on the inverse dynamic model and Appell's method based on the Gibbs function (acceleration energy). Newton-Euler formalism needs a very large number of calls of the inverse dynamic function to find the total dynamic model. The novel Appell formalism eliminates this disadvantage. Two software systems were developed both for poor numerical and advanced symbolic computations taking into account the kinematic constraints at the wheel/ground contact points by applying Lagrange-multipliers. Simulation results illustrate the effectiveness of the method for a 16 DoF vehicle in the presence of active PID suspension control.","PeriodicalId":144551,"journal":{"name":"2015 IEEE 13th International Symposium on Intelligent Systems and Informatics (SISY)","volume":"564 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120884363","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 article is to summarize energetic aspects, which are worth to consider in planning green roofs. We confirm important role of green roofs in energetic calculations of building structures with citing different methods of measurement and calculation. Aim of these methods is to specify heat conductivity of soil, which is used for the calculation of heat permeability of the whole roof structure.","PeriodicalId":144551,"journal":{"name":"2015 IEEE 13th International Symposium on Intelligent Systems and Informatics (SISY)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132739917","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 today's higher education the use of e-generation in teaching has a center stage.
