We present a work in progress for a paradigm of wall-top displays for future offices, where instead of a small desktop, we treat the available walls as the desktop. Multiple projector-camera units, mounted on pan-tilt units (PTU), allow for the creation of the conglomeration of one or more high resolution displays, whose position, size, and aspect ratio can be changed by the user. This can be achieved...
When users are interacting collaboratively in a virtual environment it cannot be guaranteed that every user has the same input device or that they have access to the same information. Our research aims at understanding the effects of such asymmetries on the user embodiment in collaborative virtual environments (CVEs). In order to do this, we have developed a prototyping platform for cooperative interaction...
This paper concentrates on the methodology-oriented components of remote laboratory arrangement in the field of electrical drive. An active learning approach proposed to support online experimentation on the servo-drives, step drives, and induction motor drives helps the students to employ novel online tools and devices, to face real-world situations, and to interact with peers in circumstances that...
The aim of this work was to develop and compare recommendation systems which use the item-based collaborative filtering algorithm, based on Hadoop and Spark. Data for the research were gathered from a real social portal the users of which can express their preferences regarding the applications on offer. The Hadoop version was implemented with the use of the Mahout library which was an element of...
A recommendation system can personalize a website for a user by suggesting items that are according to the user's liking. Recommendation systems predict the rating that a user would give to an item and recommend the top N items to the user. Collaborative Filtering algorithms are a class of knowledge discovery algorithms that give recommendations to a user based on the ratings of other similar users...
Open government is an approach that purposefully emphasizes and re-invigorates the basic principle of a "government of the people, for the people, and by the people."
In a collaborative learning environment, people face obstacles including low participation, distractions and inefficiency. With the development of collaborative systems, people in distributed group prefer Computer Supported Collaborative Learning (CSCL), making the obstacles even harder than obstacles in face to face meetings. Although Collaborative Support System (CSS), which is developed on Collaboration...
Despite the widespread dissemination of the electronic health record, the paper medical record remains an important central artefact in modern clinical work. A number of new technological solutions have been proposed to mitigate some of the configuration, mobility and awareness problems that emerge when using this dual record setup. In this paper, we present one such technology, the HyPR device, in...
Today, many people spend a lot of time online. Their social interactions captured in online social networks are an important part of the overall personal social profile, in addition to interactions taking place offline. This paper investigates whether relations captured by online social networks can be used as a proxy for the relations in offline social networks, such as networks of human face-to-face...
Collaboration is an integral element of the scientific process that often leads to findings with significant impact. While extensive efforts have been devoted to quantifying and predicting research impact, the question of how collaborative behavior influences scientific impact remains unaddressed. In this work, we study the interplay between scientists' collaboration signatures and their scientific...
In this work we present an interactive video conferencing system specifically designed for enhancing the experience of video teleconferencing for a pilot user. We have used an Embodied Telepresence System (ETS) which was previously designed to enhance the experience of video teleconferencing for the collaborators. In this work we have deployed an ETS in a novel scenario to improve the experience of...
With the advances in communication and technologies, the World Wide Web is becoming an important and rich source for information. The amount and variety of information available makes customization and personalized recommendations of utter importance. In this paper, we present a framework for the next page prediction that exploits users' access history combined with his semantic interests to generate...
Effective collaboration between engineers from different branches of engineering, such as computer and electronics engineering is a skill that requires training. Most engineers, do to some degree master this skill. Doing it effectively and as an integral part of ones work is not easy. In order to better prepare engineering students for their professional career, a module in Smart Systems is designed...
Access control is concerned with the policies that manage data sharing activities. Access control plays a crucial role in application areas such as education, health and business. However, most programming languages and programming environments do not naturally provide support for implementing access control policies requiring access control policies for systems to be coded as part of the development...
Personalized entertainment items recommendation is required to help millions of people narrow the universe of potential items to fit their unique tastes. These services usually depend on a machine-learning algorithm, which breaks down items into long lists of attributes and matches these elements to a user's preferences. A set of such algorithms have been proposed. Most of these, such as collaborative...
Test case prioritization is a technique for selecting those test cases, which are expected to outperform for determining faulty modules earlier. Different phases of software development lifecycle represent the total software from different point of views, where priority module may vary from phase to phase. However, information from different phases of software development lifecycle is rarely introduced...
Cloud computing technology has been influential in overcoming problems in e-learning systems, such as the lack of scalability and storage limitation. Therefore, a framework for applying cloud computing on e-learning systems has been prepared. However, to develop a cloud-based e-learning system that matches well with the learners' needs and solves the current problems, it is important to know the learners'...
Collaborative learning environments bring together learners from different cultures and social contexts, around a common task. These learners interact both with each other and with computers. Hence, a dual problem arises: how to model and integrate socio-cultural factors that characterize these learners? How to design and develop culture-aware collaborative learning environments? This paper addresses...
The paper presents a review on, and analysis of, the design, development and evaluation of experiences of learning through the ‘Sustainability Serious Game’. The mobile game has been developed as means of helping public authorities to collect information and feedback on how public spaces could be improved based on collective intelligence procedures. Furthermore, as part of enhancing learning, the...
Currently, numerous researches made several treatments on the traces recorded from distance learning environments. These researches collect traces from different sources to solve several problems: (i) support learners, (ii) engineering/reengineering of learning devices and (iii) adaptation/personalization of learning environments. The traces describe the learners' actions where they interacting with...
