Remote User Interface for ABB IRB120 Robot Using TCP/IP Communication

Abstract This paper presents the development and implementation of a remote user interface for the ABB robot using the TCP/IP protocol. The study focuses on building a user-friendly interface in Matlab environment that enables precise and secure control of the robot’s operation with an educational support role in teaching the basics of robotics. The remote application offers a simple and intuitive controlling mode, providing users with a firsthand experience of the robot’s capabilities through predetermined actions. Additionally, the advanced mode allows users to test the robot’s functionality and perform simple tasks. The use of asynchronous communication contributes to the stability and performance of the remote control application.

Using Film and Online Group Blogs to Cultivate a Community of Inquiry: A Case Studied at a University of Technology in South Africa

Despite the integration of technology in higher education, there is currently a paucity of research in the field of social entrepreneurship education in South Africa regarding the use of asynchronous communication supported by teaching resources in cultivating critical learning capacities through autonomous learning. Informed by the community of inquiry framework of Garrison, Anderson, and Archer (2007), this study examined the cognitive, social and teaching presences among pre-service educators in online group blogs in relation to the film Who cares? which was used as a primary teaching resource in a social entrepreneurship module. In this study, the participants’ posts and comments were collected, coded and analysed using ATLAS.ti. The results revealed that, after viewing the film, the participating pre-service educators established high cognitive, social and teaching presences, respectively. The results of the study further illustrated that online group blogs in combination with film could provide pedagogical spaces for students to establish a community of inquiry in which pre-service educators’ critical learning capacities were enhanced through autonomous learning.

Using search-based algorithms for Ajax event sequence generation during testing

Modern Web applications offer a rich and unique user experience by taking advantages of the so called Web 2.0 technologies, among which Ajax. Ajax supports the intensive use of asynchronous communication between client-pages and the Web server and it allows on-the-fly manipulations of client-pages content and structure to realize a rich, dynamic and interactive user interface. Correspondingly, new types of faults that cannot be easily revealed by existing Web testing techniques are associated with modern Ajax-based applications. In our previous investigations, we used state-based testing for event sequence generation and it proved to be quite effective in exposing Ajax specific faults. However, the search space of the semantically interacting event sequences is huge, as it can grow exponentially with the event sequence length. In this paper, we apply search-based algorithms, namely hill climbing and simulated annealing, to the problem of generating maximally diverse event sequences of various lengths. In this way, we control the size of the generated test suites, while keeping the included test cases as diverse as possible. We evaluate the performance of the algorithms on two open source Ajax applications.

Design Team Communication and Design Task Complexity: The Preference for Dialogues

The way in which dialogues and group meetings affect the progress of multidisciplinary architectural design teams can be easily underestimated by managers. This is due to the importance of group meetings to review designs, share information, make decisions and hence progress the design. The aim of this paper is to discuss how design dialogues and design team meetings facilitate team communication. A review of research into design team communication and performance using a project website provides an insight into how design team members used and changed their synchronous and asynchronous communication while adopting the project web. Case studies were used to investigate changes in communication practices affecting team performance due to project web use. Research findings reveal a preference among design team members for dialogue as their favourite communication medium despite the growing use of asynchronous communication by teams. Results are discussed against research findings from communication in design and management team meetings. Implications for design managers, concerned with improving communications and the management of design, are discussed in the light of the research findings.
