Self-Organizing Maps (SOM) [ ] are a popular clustering and visualization algorithm. Several implementations of the SOM algorithm exist in different mathematical/statistical softwares, the main one being probably the SOM Toolbox [2]. In this presentation, we will introduce an R package, SOMbrero, which implements several variants of the stochastic SOM algorithm. The package includes several diagnosis...
Maintaining an external focus of attention (FA), as with virtual reality exercise gaming, may be effective in encouraging greater dynamic lateral movements and greater weight bearing for individuals post stroke. This study sought to compare center of pressure movements for individuals post-stroke under three conditions (internal FA, external FA, virtual reality) and compare these differences to healthy...
The aim of this paper is to present a comparison between the performance of virtual and conventional rehabilitation of upper limb gross motor function. To this purpose we define two rehabilitation exercises with a high degree of similarity. The virtual exercise is a computer implementation of the well known game “whack a mole” and the conventional exercise is based on a “shape-sorter” didactic toy...
The aim of the current study was to examine the effectiveness of a meta-cognitive intervention program that uses virtual reality training (VAP-S) to improve the implementation of a shopping task among adolescents with Autism Spectrum Disorder (ASD). The study included 56 adolescents aged 11–19 with ASD, of which 37 performed the intervention program while the remaining 25 formed a control group who...
Multi-label text classification plays a significant role in information retrieval area. The effectiveness of the techniques is especially important in the case of medical documents. In the paper, application of feature selection methods for improving multi-label medical text classification is discussed. We examine combining problem transformation methods with different approaches to feature selection...
During the aging process, cognitive decline occurs in different functions such as memory, language, executive functions and attention. In this sense, TV Neurones, a cognitive training software, was developed and can be used by health professionals to maintain and/or restore cognitive abilities of older people. However, there are no validation studies of the Portuguese version of TV Neurones. This...
Games development can be considered a constantly evolving area that requires a considerable effort by the developers to create elements that capture the players' attention. Researches indicate that games can produce a high engagement, which indicate their potential as tools for education, training or awareness. Games designed with a primary purpose other than entertaining, such as the applications...
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...
Deep learning is a sub-set of machine learning practice employing models based on various learning network architectures and algorithms in the field of artificial intelligence. Businesses planning to adopt a deep learning solution should comprehend a set of complex choices in hardware, software, configuration and optimizations to setup a functional deep learning solution. This paper will describe...
With the increase in the availability of information regarding energy use, there is an increase of forecasting software on the energy market, that can forecast on the short, medium and long term. In the paper, there is presented a software solution for load forecasting using Artificial Neural Networks (ANN) method. In the case study, we have written an application for a consumer which is engaged in...
This study aims to group hotels in terms of the level of IT competencies, and to characterize each group according to contingency factors (size, category, type of customer, among others) and the characteristics of the human resources that work in them. The study focuses on Portuguese hotel industry, based on a sample of 163 hotel professionals, across 3, 4 and 5 star hotels categories. The performance...
There is currently a strong demand for Information and Communication Technologies professionals in Portugal. This demand requires that higher education institutions prepare their graduates adequately, not only in technical skills, but also in terms of the so-called soft skills. In this paper, we describe a strategy that is being implemented, in recent years, in two higher education Information and...
In Transylvania's University — Creativity Laboratory we try to do complex trainings of students and high school children's — connected with the their preparation for LabVIEW (Laboratory Virtual Instrumentation Engineering Workbench) Academy examinations. The graphical nature of LabVIEW makes it easier to develop working code faster — quickly drag and drop built-in functions to simplify acquisition,...
This paper contains a description of programs currently available for detecting physiological changes in the human reaction to a stressful situation. For each program described what is being evaluated, what we get like output of the program, advantages, disadvantages and potential contribution to commercial security. As alternative solutions are included training programs to help security personnel...
The paper describes a new and efficient evaluation method to test very quickly and properly the sportive aptitudes for young subjects, reported to locomotion function. First of all is about the body stability, in terms of center of mass (COM) displacement amplitudes. The key aspect on the developed and proposed method is a software application, programmed and tested as main research activity, allowing...
Machine Learning (ML) is an attractive application of Non-Volatile Memory (NVM) arrays [1,2]. However, achieving speedup over GPUs will require minimal neuron circuit sharing and thus highly area-efficient peripheral circuitry, so that ML reads and writes are massively parallel and time-multiplexing is minimized [2]. This means that neuron hardware offering full ‘software-equivalent’ functionality...
It is shown that virtual laboratory complexes identical to real physical stands may provide an alternative in laboratory workshop for students of technical specialties of higher educational establishments. The basic requirements for virtual complexes are formulated and graphic programming medium LabVIEW is proposed as a platform for their creation. An example of a virtual laboratory complex for the...
Large software development organizations adopting agile methods need solutions and models to help scale agile to fit their needs. During recent years, several frameworks for scaling agile have been created by consultants, including the Scaled Agile Framework (SAFe), Large-scale Scrum (LeSS) and Disciplined Agile Delivery (DAD). However, research on how these frameworks are adopted in practice is seriously...
Aside of main stream of usage of Air Traffic Control (ATC) simulation technology, focusing on training and education of both new and existing staff, there is another possibility, how these technology devices could be operated effectively for a new domain. One of such area is contemporary experimented inside the Air Force and Aircraft Technology Department of Faculty of Military Technology. Continuing...
In crowdsourced testing, it is beneficial to automatically classify the test reports that actually reveal a fault – a true fault, from the large number of test reports submitted by crowd workers. Most of the existing approaches toward this task simply leverage historical data to train a machine learning classifier and classify the new incoming reports. However, our observation on real industrial data...
