This paper deals with the description of concept of a virtual laboratory designed for educational purposes and deployment of processor-in-the-loop (PIL) concept with the use of the REX Control System. It also presents the case study regarding control of a simple inverted pendulum on the cart. The below mentioned techniques represent modern, accessible and adaptive teaching methods supporting a distance...
This research aims to study the neural influence of conflict between brand and product performance on consumer decision. In the experiment, stimuli of products with brand and performance information were displayed randomly. 22 subjects need to decide whether to buy, while the event-related potentials (ERPs) were recorded. The stimuli were divided into four conditions based on the consistency of brand...
This paper aims to present an ongoing PhD research project in Information and Communication in Digital Platforms course of University of Aveiro and University of Porto. This study, which started in June/2016 and is 24 months long, aims to study, conceptualize, prototype and validate a system for personalized and dynamic recommendation of informative videos about public and social services, for later...
The adoption of agile methods is difficult. No rework metrics, changing scope and requirements are the main difficulties in adopting these. In this sense, the Trace++ approach aims to facilitate the adoption of agile methods by teams that work with traditional methods. However, to obtain use-scale, this paper proposes a tool to facilitate the requirements traceability processes, in order to scale...
It has been shown in previous studies that haptic guidance improves the learning outcomes of handwriting motor skills. In this paper, we present a comparison between full guidance and partial guidance using a haptic learning tool which supports these two modes. The full guidance mode leads the user along a pre-recorded trajectory, whereas the partial guidance mode allows the user a free movement and...
Online experimentation have become a common resource in education since the virtual and remote labs (VRLs) allowed the users to interact with a system without been in a laboratory environment. The science and engineering areas needs to teach their student in experimental practices and this implies, in most cases, costly and complex systems. This work shows how new technologies allows a low cost online...
The preservation of the sites, monuments and other spaces, cultural heritage of the Humanity, has been one of the areas of greater use of computer graphics. This paper presents a methodology of expeditious and low-cost work aimed at virtual recreation of these historical spaces, which, through their availability on the web, allows its analysis and study by experts, as well as their access to the public,...
This paper presents the development of a virtual reality simulator for the management of a UAV (Unmanned Aerial Vehicle) focused on improving the quality of life of grown-up people. The present research has collected characteristics of gestures and physical movements from users made by other related research in order to study the same interaction within a virtual world. Through this research a smaller...
The present research aims to measure the relationship of economic and financial profitability with the use of business accounting software. For this purpose, a sample of 146 Ecuadorian SMEs was used in 2015. The H-test of Kruskal Wallis was applied and it was determined that there were no differences between companies in the case of financial profitability and economic profitability. Companies that...
In this article we approach the current state of art regarding programming education. We analyze the current constraints and challenges that students have been facing when learning programming, as well as the methodologies adopted by teachers and researchers to overcome these adversities. We propose the implementation of gamification to motivate and encourage students to achieve better results and...
The development of expert Systems to support to different areas in the medical field has important implications; it is possible to emphasize the possibility of having timely and effective treatments. Early detection of an anomaly and an effective control of this can prevent the progression of a disease. In this work, shows the progress in the design and implementation of an expert system for ophthalmologic...
Computerized systems employed for the analysis of cardiotocographic signals have become almost indispensable tools in fetal monitoring, for which evaluation of fetal heart rate signals plays a key role. Consequently to the diffusion of these systems, new software and complex signal processing methodologies are spreading and are gaining more and more interest. For testing the performances of new software...
Vision is one of the most important senses that helps people interact with the real world. Commonly visually impaired develop their other senses to feel their surroundings, but in certain cases, this is not enough. The senses can be disturbed by noise or illness. For this reason, many artifacts have been developed to help this group of people. Artifacts such as white canes or guide dogs help sightless...
Visual saliency models are difficult to implement in hardware for real time applications due to their computational complexity. The conventional digital implementation is not optimal because of the requirement of a large number of convolution operations for filtering on several feature channels across multiple image pyramids [1], [2]. Here, we propose an alternative approach to implement a neuromorphic...
In view of the problems that existing visual interface development tool are the interface display code and the logic code are higher coupled, and little weaker in portability and lower extensibility. This paper presents a cross platform visual interface development tool based on template and introduces its key design technologies and system structure. The system uses a unified template management...
An existing psycholinguistics experiment is extended with EEG measurement to analyze the spatiotemporal distribution of activities during a bilingual lexical access task. A low-cost custom trigger hardware was developed to provide event timestamps of the experiment stimulus and response to the EEG apparatus. The experiment was repeated on a subject group of 20 students, and our processing software...
This paper analyzed the temporal and spatial distribution of the CNKI database to infectious diseases as the theme of the literature; then using information visualization software CiteSpace to draw the main research institutions in the field of infectious disease research, knowledge mapping representatives, and detailed analysis of its last words as hot words; sources of infectious disease research...
Learning to program is a challenging task. Novices need to have an accurate understanding of the program execution at the conceptual level provided by the programming language. This level of execution is often referred to as the notional machine, which is often easier to understand through program visualizations.
Storyline visualization, as a process of illustrating data that has a course of events via a visual medium, has been used in the area of film making for a very long time. Not so long ago, it has moved from the paper version to the digital word allowing for a wider usage. In this paper we propose its usage as a teaching tool in the area of literature reading for the Croatian class (primary language)...
During software development, code clones are commonly produced, in the form of a number of the same or similar code fragments spreading within one or many large code bases. Numerous research projects have been carried out on empirical studies or tool support for detecting or analyzing code clones. However, in practice, few such research projects have resulted in substantial industry adoption. In this...
