Social media platforms contain interesting information that can be used to directly measure people' feelings and, thanks to the use of communication technologies, also to geographically locate these feelings. Unfortunately, the understanding is not as easy as one may think. Indeed, the large volume of data makes the manual approach impractical and the diversity of language combined with the brevity...
Increasing demand of multimedia functions in mobile influenced systems provides limitations to battery usage in terms of power. To overcome this problem SLIMbus is designed by MIPI alliance which gives higher bus bandwidth by supporting more number of data channels, supports clock gear mechanism that gives less power consumption in hand held devices by changing the clock frequency dynamically. SLIMbus...
This work describes the evaluation of problems students have with Moodle2 — an e-learning platform. Special focus lies on international students who could overcome language problems by using learning technology. This includes investigation of how the definition ofproblem generating factors can be evaluated by using the evaluation tool CoALa based on the research method Repertory Grid. An evaluation...
The aim of this paper is to present a collaborative social platform developed as a research project to enhance serious collaboration between the students of ESPRIT (School of Engineering, Tunis, Tunisia). The platform focuses on automating the creation of opportunistic collaboration between students, based on the type of the tasks conducted (content creation, project realization, problem resolution…),...
Due to the predictable nature of network transfers in media production industry, advance bandwidth reservation results in higher bandwidth utilization and improved network performance. However, in unreliable networks, this may fail. As a first provisional stage, deploying protection mechanisms ensures that the schedule remains valid when the system is in operation. Constant monitoring and modification...
A concept for a Manufacturing Technology Online Course, which combines the MOOC approach and the use of a remote laboratory is presented. Hence, this online course is a combination of a MOOC-concept and a physically existing but tele-operatively usable experimentation laboratory for real engineering experimentation. Developing this online course can be either used as an advertising for mechanical...
Learning and teaching processes are complex and depend on different surrounding conditions [1] (e. g. missing learning/teaching skills [2], different affinity to "new media" [3], insufficient time [4]). Although different (didactical) concepts are supposed to lead to good learning outcomes, experience at our university shows that the lecturers have problems with the transformation and integration...
Colors play a vital role in letting us perceive and distinguish between the various things that exist in our surroundings. While many of us are able to do so perfectly, some are not blessed with a perfect visual ability. The answer to the question that how fine is our color vision, depends upon some factors which we will be explaining in detail in this paper. When these parameters deviate from their...
Now a day's large amount of digital information such as video, audio or image is spread over the internet. So it should be a great challenge for all researchers to provide security to such a type of digital data. Also the piracy and copyright is emerging issue when digital information in the form of video, audio & image is transmitted over the transmission media. So to prevent the problem of piracy...
Robots are more and more leaving our labs and entering natural interaction settings, such as homes, care facilities, factories, kindergartens, museums, and many more. In the HRI research community, we are aware of all the challenges involved in studying autonomously behaving agents “in the wild”. In order “not to go wild” we want to discuss best practices as well as pitfalls in studying robots in...
Many researchers have started to explore natural interaction scenarios for children. No matter if these children are normally developing or have special needs, evaluating Child-Robot Interaction (CRI) is a challenge. To find methods that work well and provide reliable data is difficult, for example because commonly used methods such as questionnaires do not work well particularly with younger children...
GPS measurements are often affected by errors. This is mainly due to the fact that GPS signals need to pass through the atmospheric layers and this gives rise to unpredictable delays. In this paper we introduce M-DGPS, a novel algorithm to post-processing correct geodetic tracks by means of data coming from multiple DGPS stations. The main idea of M-DGPS is to use a set of DGPS stations as Voronoi...
We propose a pixel similarity based Betacam dropout detection method. Proposed method aims at detecting errors, having vertically similar pattern without considering sequential frame when archiving a tape-based content to a file-based system. Moreover, this method works along with a real-time instant Quality Control(QC) system with less false-alarm.
The combination of personalization parameters for providing personalization of learning scenarios has been an important subject of research in recent years. Several systems have been reported in the literature for assembling the mentioned parameters by reusing existing parameters. However, very little research is available that focuses on optimizing this composition. This work proposes a new approach...
The integration of social media technologies with second screen devices facilitates the social interaction concerning online broadcasted media events that we refer to as the social soundtrack. For this research, we assess the change of Super Bowl 2015 related conversations on various social media platforms, namely Twitter, Instagram and Tumblr via categories (commercials, musicals and game) for three...
While fans of classical music were found to be underrepresented on social media and music streaming platforms, they constitute an important target group for music recommender systems. We therefore focus on this group of listeners and investigate a wide range of recommendation approaches and variants for the task of music artist recommendation. Within the group of classical music listeners, we further...
Rumor events differ in how and where they originate, what topics they address, the emotions they invoke, and how they engage their audience. In this paper, we study various semantic aspects of rumors and analyze the motivational and functional roles they play. Using Twitter as a case study, we develop a framework to characterize rumors. Our characterization covers intrinsic and extrinsic factors,...
Constructing topic hierarchies from the dataautomatically can help us better understand the contents andstructure of information and benefit many applications insecurity informatics. The existing topic hierarchy constructionmethods either need to specify the structure manually, or arenot robust enough for sparse and noisy social media data suchas microblog. In this paper, we propose an approach toautomatically...
