Advancing preuniversity students' computational thinking skills through an educational project based on tangible elements and virtual block‐based programming
(Wiley, 2020-11)
University students enroling in Science, Technology, Engineering and Mathematics (STEM)‐related studies such as computer science continue to decline, even though worldwide educational policy reports warn about the need for ...
Tailoring the spatio-temporal distribution of diffractive focused ultrashort pulses through pulse shaping
(Optical Society of America, 2018)
Focusing control of ultrashort pulsed beams is an important research topic, due
to its impact to subsequent interaction with matter. In this work, we study the propagation
near the focus of ultrashort laser pulses of ~25 ...
Analysis of single‑ and dual‑dictionary strategies in pedestrian classification
(Springer Verlag, 2018)
Sparse coding has recently been a hot topic in visual tasks in image processing and computer vision. It has applications
and brings benefts in reconstruction-like tasks and in classifcation-like tasks as well. However, ...
A study of deep neural networks for human activity recognition
(Wiley, 2020)
Human activity recognition and deep learning are two fields that have attracted attention in recent years. The former due to its relevance in many application domains, such as ambient assisted living or health monitoring, ...
Parabolicity, Brownian Exit Time and Properness of Solitons of the Direct and Inverse Mean Curvature Flow
(2019-10-05)
We study some potential theoretic properties of homothetic solitons n of the MCF
and the IMCF. Using the analysis of the extrinsic distance function defined on these
submanifolds in Rn+m, we observe similarities and ...
Supporting Connectivism in Knowledge Based Engineering with Graph Theory, Filtering Techniques and Model Quality Assurance
(Elsevier, 2018-10)
Mass-customization has forced manufacturing companies to put significant efforts to digitize and automate their engineering and production processes. When new products are to be developed and introduced the production is ...
Equivalence of chatbot and paper-and-pencil versions of the De Jong Gierveld loneliness scale
(Current Psychology, 2020-10-13)
Technological progress provides health professionals with an excellent opportunity to take advantage of these developments and contribute to the development of efficient ways of diagnosing, monitoring, treating and assisting ...
The Smartphone-Based Offline Indoor Location Competition at IPIN 2016: Analysis and FutureWork
(MDPI, 2017)
This paper presents the analysis and discussion of the off-site localization competition track,
which took place during the Seventh International Conference on Indoor Positioning and Indoor
Navigation (IPIN 2016). Five ...
Mean curvature, volume and properness of isometric immersions
(American Mathematical Society, 2017)
We explore the relation among volume, curvature and properness
of an
m
-dimensional isometric immersion in a Riemannian manifold. We show
that, when the
L
p
-norm of the mean curvature vector is bounded for ...
Three-dimensional trees for virtual globes
(Taylor & Francis, 2014)
One of the problems in virtual globes technologies is the real-time representation of vegetal species. In forest or garden representations, the low detailed plants produce a lack of realism. Efficient techniques are required ...
