Photovoltaic (PV) module degradation in the field is a known issue; however, understanding the modes and mechanisms in which modules degrade is still a major undertaking for researchers. To understand the degradation modes and mechanisms, both nondestructive and destructive characterization techniques need to be employed. This paper presents the results and conclusions obtained based on a few major...
Emotional expression is significant as an essential part in our daily life. Ubiquitous presence of mobile technology-mediated communication creates various affective occasions and affords rich emotional expressions with lower complexity of input. In this paper, we aim to design a simple way of emotional expression through finger movements on mobile phone touch screen allowing for richer affective...
Keeping up with rapidly emerging research fronts in various inter-disciplinary fields requires significant effort from scholars and researchers. These users are concerned not only with finding relevant articles or websites, but also for gaining the understanding of key articles, authors, citation information, and current trends. Several tools such as Action Science Explorer (ASE) have been developed...
Drawing principles, or aesthetics, are important in graph drawing. They are used as criteria for algorithm design and for quality evaluation. Current aesthetics are described as visual properties that a drawing is required to have to be visually pleasing. However, most of these aesthetics are originally proposed without consideration of graph structure information. Therefore their ability in visually...
Adaptive educational hypermedia (AEH) is a learning tool that adapts learning content and flow to students' needs and offers students a freedom to explore materials. Adaptation and personalization in AEH are produced from interaction of learner, pedagogic, domain, adaptation, and presentation models. This paper discusses Knowledge Map, a prototype tool for managing and visualizing domain model of...
Many studies have widely accepted the assumption that learning processes can be promoted when teaching styles and learning styles are well matched. In this study, the synergy between learning styles, learning patterns, and gender as a selected demographic feature and learners' performance were quantitatively investigated in a blended learning setting. This environment adopts a traditional teaching...
This paper describes the advancements on the Metaplastic Arts and Design research field through its own cyber media and interdisciplinary methodologies. It enhances the metaplastic discipline within art and sciences application fields. In the conclusion of this paper some examples of applications are introduced.
This paper describes the results of a comparative pilot study of three different approaches to deliver three-dimensional content in an Engineering Design Graphics textbook using Augmented Reality: Desktop Augmented Reality, Mobile Augmented Reality, and an interactive 3D viewer. This work builds on a previous version of our augmented book, which only implements Desktop Augmented Reality. In this extended...
Audio-Games (AGs) are electronic games that mainly (or exclusively) implement auditory means to express the game's plot, mechanics and content. AG players need to concentrate on perceiving sound, in order to understand and play the game. Recent developments in the field of edutainment suggest that AGs can be implemented not only as entertaining systems, but also as valid tools for research and education...
Using a research-to-practice model to teach undergraduate engineering students about the design process, we adopted a classroom activity that used design process data derived from research and represented in the form of timelines as an advance organizer to facilitate student learning. We also developed a set of assignments, including some where students created and shared their own representations...
Adaptive learning systems require student model repository that store student's data in order to provide learning materials tailored to the student's characteristics. Student's learning style is one of the most crucial factors to be identified in order to update the student's profile. Hence, the need for a high accurate classifier that deals with the students data and generates suitable number of...
A learning style index is a model that can help learners to identify their learning preferences and hence adopt suitable learning materials that can enhance their learning process. On the other hand, teachers also can gain by knowing their students' learning preferences. It helps them to prepare a suitable teaching styles and materials that can fit with their students' preferences. This paper is concerned...
We experimentally evaluated the effect of display resolution on physiological and psychological state while viewing video content at 4K and 2K on a 65-inch 4K TV. Four kinds of video content (two types of scenic material and two types of material with movement and action) were used. Each program comprised two minutes of 4K and two minutes of 2K content. The results showed that the scores for “presence,”...
Dyadic brain interactions during eye contact engage multiple processes and recruit multiple networks. To fully characterize these concurrent activities, it's essential to establish the neural basis for reciprocal social interaction. So far most approaches in this pursuit suffered from the limitations in either insufficient dyadic test instruments or entwined reciprocal and non-reciprocal cerebral...
A keyword-based query is not sufficient for retrieving presentations. We assume that episodic memories about authoring slides and giving a presentation can be used for query because users easily recall and recognize slides associated with such memories. In this study, we present slide retrieval based on research episode networks that are a network composed of slides, episodic information and the links...
O uso de Conjuntos de Manobra e Controle de Potência (CMCP) nos sistemas elétricos industriais (SEI) típicos das indústrias petroquímicas, tanto de média quanto de baixa tensão, se depara com diferentes desafios, associados a sua especificação e operação, para se obter soluções que garantam a qualidade da energia elétrica a ser distribuída. Muito destes problemas estão relacionados aos seus componentes,...
Programmers often re-appropriate code or new programming skills they find in unfamiliar code within their own programs [1], [2]. This process enables programmers, including novices, to acquire new programming knowledge while working on their own programming projects. Unfortunately, novice programmers often have difficultly understanding and integrating existing code into their own programs [3], thereby...
In this paper, we present the vision of an open source learning analytics platform, able to harvest data from different sources, including e-learning platforms and environments, registrar's information systems, alumni systems, etc., so as to provide all stakeholders with the necessary functionality to make decisions on the learning process. The platform's architecture is modular, allowing the introduction...
The quality in the presentation of the educational material as well as the personalization of the educational process in a distance learning environment have been and still remain open issues. This is due to the fact that on the one hand, the educational material has to be incorporated into the new artifacts and, on the other hand, the educational process should change in a dynamic way, according...
