The MOOCs offers technologies which emerge as an alternative to support the blending of face-to-face pedagogies and virtual activities. However, a blended learning experience is influenced by several factors, such as: the student's attitude to learn; a well-known learning script; and interactions and group dynamic. This article proposes MOOCs scenarios based on the experience of two collaborative...
The description of workshop on project realization in international students teams with the three different ways of dissemination of the results is presented in this paper. The assumptions and purposes of the workshop are specified and few parts of the schedule of activities are given to show the mode of this event realization. Some examples of evaluation of learning skills in presentation are mentioned.
In recent years, the number of appliances connected to the Interned has steadily increased thanks to the wide popularity of WÌFÌ/3G enabled mobile devices. This has led to an increase of multimedia resource consumption, causing traffic overload problems for classic resource providers. Different solutions have been studied to shift this traffic overhead from the server(s) towards the client(s) through...
Museums and similar institutions are historically locations where content is typically only intellectually appreciated following linear visiting patterns. No interactions, in fact, are typically implemented and no possible choice is drawn in front of a visitor regarding the exhibits that will be shown. In addition, exhibition experiences are typically confined within their buildings' walls, not projecting...
Popular videos are often clicked by a mount of users in a short period, and take most of the network traffic. With content recommendation, the popular contents could be broadcast to the potential users in wireless network, to save huge transmitting resource, as described in Content Aware Soft Real Time Media Broadcast (CASoRT) system. With the users' communication log in the Chinese commercial cellular...
Home automation revolves around the user as well as the technology in terms of usability and features. The aim of this paper is to provide an holistic and practical view on the design of a real home automation system. This overview is based on a practical experience gained by creating a real wireless home automation system. Our discussion is focused on two main issues: the actual communicating devices...
The first private chapel for which the Pope granted permission in the middle of the fifteenth century, in Palazzo Medici in Florence, frescoed with the Procession of the Magi by Benozzo Gozzoli, has recently become the setting for an experience of guided perception with the support of multimedia technologies and augmented reality in the workshop “Procession in time through to the splendour of the...
Although valuable crime information is available in human-readable form in online newspapers and electronic archives, software systems that can extract and present relevant information are limited and are of significant interest to researchers in the field of information extraction. This work aims to extract available drug crime information from online newspaper articles. This work has the following...
Software development initially used traditional methodologies which have been in the mainstream until the advent of agile methodologies. It is often thought that as traditional methods would be eventually replaced by new methods, it still remains the closest link to a naturally progressive route although the mind-set wants to get rid of the old and get in with the new. But it is not the replacement...
In open multi-agent systems, agents may hide or lie about information regarding some events. In order to avoid such deception, a multi-agent system must be designed to test the confidence of agents. In this paper, we present a new approach to agent-based confidence modeling. This approach integrates two confidence requirements, namely, trust and certainty. We use fuzzy logic in representing the importance...
In this study we focus on the influence of the voice of a speech corpus on the quality of text-to-speech (TTS) systems. Therefore, we selected a set of attribute scales which consists of items related to the 5 perceptual quality dimensions of TTS systems and of items which are used in studies concerning the likeability of voices. We selected 5 different voices of the TTS systems IVONA and ACAPELA...
In the long term research of visual attention, various computational models have been proposed. However, most of those works do not take audio into consideration. In practice, visual signals often come along with audio. Therefore, it is natural to investigate the influence of audio on visual attention. In this paper, we focus on the problem of when will audio influence visual attention during video...
This paper presents the influence of perceived texture regularity on the visual quality of textures that are synthesized through parametric and non-parametric approaches. It is shown through subjective testing that textures with different degrees of perceived regularity exhibit different degrees of vulnerability to texture synthesis artifacts. The paper also proposes a method for adaptively selecting...
In order to cater for user's quality of experience (QoE) requirements, HTTP adaptive streaming (HAS) based solutions of video services have become popular recently. User QoE feedback can be instrumental in improving the capabilities of such services. Perceptual quality experiments that involve humans are considered to be the most valid method of the assessment of QoE. Besides lab-based subjective...
Multi-exposure image fusion is considered an effective and efficient quality enhancement technique widely adopted in consumer electronics products. Nevertheless, little work has been dedicated to the quality assessment of fused images created from natural images captured at multiple exposure levels. In this work, we first build a database that contains source input images with multiple exposure levels...
In this study, the effect of pure synchronous and asynchronous transmission delay was examined in an interactive videotelephony setting. It was found that the conversational quality rated by participants of the study was clearly dependant on the tested conditions. This outcome can to some extend be ascribed to the used task which facilitated the usage of the visual channel for social interaction....
Most studies on the perceptual quality evaluation of multi-media services are limited to short media samples or epi-sodes, although typical usage of services occurs in a more regular way over longer periods of exposure (weeks, months or years). So far, it is unclear how the experience of individ-ual episodic use is integrated to form an experience of one service as a whole, spanning over multiple...
Since olfactory sense is gaining ground in multimedia applications, it is important to understand the way odor pleasantness is perceived. Although several studies have explored the way odor pleasantness perception influences the power spectral density of the electroencephalography (EEG) in various brain regions, there are still no studies that investigate the way odor pleasantness perception affects...
Subjective quality tests give important information about the user's perception on the quality of an audio or video signal. These tests are helpful but usually lack information about the user's cognitive state. This might be crucial when consuming a service, as lower quality services may lead to a less frequent use. Therefore, physiological measures have become more popular in the domain of quality...
A first step towards creating automatic measures of image aesthetic appeal is understanding its appreciation via subjective testing. Nevertheless, reliably setting up such tests appears to be challenging, as aesthetic appeal is proven to be influenced by a number of subjective factors. In this paper we investigate four scale types for aesthetic appeal rating and assess their ability to provide general...
