Tiphys: An Open Networked Platform for Higher Education on Industry 4.0
No full textObjective of Tiphys project is building an Open Networked Platform for the learning of Industry 4.0 themes. The project will create a Virtual Reality (VR) platform, where users will be able to design and create a VR based environment for training and simulating industrial processes but they will be able to study and select among a set of models in order to standardize the learning and physical processes as a virtual representation of the real industrial world and the required interactions so that to acquire learning and training capabilities. The models will be structured in a modular approach to promote the integration in the existing mechanisms as well as for future necessary adaptations. The students will be able to co-create their learning track and the learning contents by collaborative working in a dynamic environment. The paper presents the development and validation of the learning model, built on CONALI learning ontology. The concepts of the ontology will be detailed and the platform functions will be demonstrated on selected use cases
A Virtual Reality Laboratory for Blended Learning Education: Design, Implementation and Evaluation
Get PDFLaunched during the pandemic, the EU-funded JANUS project aimed to ensure the continuity of student workshops at universities using a virtual reality (VR) robotics laboratory. With the return to normality, the project has been redesigned to capitalise on the positive outcomes of the experience. The VR lab provides safe and unrestricted access to the labs and experiments with the machines, reducing the consequences of student mistakes and improving the user experience by allowing the experiment to be repeated from different angles, some of which are impossible to access in the real lab. In addition, integration with an interactive learning platform called “ViLLE” allows for continuous assessment of the learning experience. Self-evaluation of the material taught and learned can be integrated with the execution of the exercises that pave the way for Kaizen. Two VR workshops for the blended learning of robotics were developed during the JANUS project. Their evaluation reported favourable responses from the students whose learning performance was indirectly measured
Why Fuzzy Cognitive Maps Are Efficient
Get PDFIn many practical situations, the relation between the experts’ degrees of confidence in different related statements is well described by Fuzzy Cognitive Maps (FCM). This empirical success is somewhat puzzling, since from the mathematical viewpoint, each FCM relation corresponds to a simplified one-neuron neural network, and it is well known that to adequately describe relations, we need multiple neurons. In this paper, we show that the empirical success of FCM can be explained if we take into account that human’s subjective opinions follow Miller’s seven plus minus two law
Strategies to Enhance Students' Capabilities of Abstract Thinking - the Use of Case in Different Learning Situations
No full textVR Training for Security Awareness in Industrial IoT
No full textPart 16: Virtual Reality in Education for Industry 4.0International audienceVirtual Reality technology provides new solutions and more efficient opportunities for a revolutionary new manufacturing training environment. This work focus on presenting a VR training environment on a new and promising IoT communication protocol, the Low-Power Wide-Area Networks (LPWAN). The LP-WAN have recently emerged as a standard IoT communication system that satisfies the challenges of industrial networks by enhancing their reliability and efficiency. The LPWAN is a promising response to the limitations showed by current IoT technologies. Here are exploited the possibilities of the 3D virtual world technology to create experiential learning simulations, which address IoT users’ real needs for privacy and security awareness. To this aim, a 3D role playing game is introduced and a group of master students have evaluated its ability to help them for handling the security features of LPWAN
Dow Theory\u27s Peak-and-Trough Analysis Justified
Get PDFIn the analysis of dynamic financial quantities such as stock prices, equity prices, etc., reasonable results are often obtained if we only consider local maxima ( peaks ) and local minima ( troughs ) and ignore all the other values. The empirical success of this strategy remains a mystery. In this paper, we provide a possible explanation for this success
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Development of weather application for enhancing sea safety and rescue operations
No full textmong many issues which affect the marine-related daily activities, the weather conditions are considered one of the most important. In this study, all the tools and the methods were used to develop a modern weather application which is able to support the quality of vessel services in the sea safety and rescue operations, is presented. The weather application can operate using as basic data source continuous measurements from a mobile meteorological station on a pilot vessel. The meteorological station records automatically all the measurements of its sensors while appropriate modules in the internal structure of the system analyze the initial information and provide final outputs. In the framework of the LINCOLN Project where new concepts of added-value specialized vessels and relative automated services, are developed and promoted, this application is intended to provide accurate and on-site information about weather conditions
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
