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, ...
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 ...
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 ...
DAT-CNN: Dual Attention Temporal CNN for Time-Resolving Sentinel-3 Vegetation Indices
(IEEE, 2022-03-22)
The synergies between Sentinel-3 (S3) and the forthcoming fluorescence explorer (FLEX) mission bring us the opportunity of using S3 vegetation indices (VI) as proxies of the
solar-induced chlorophyll fluorescence (SIF) ...
Video Games and Outdoor Physical Activity for the Elderly: Applications of the HybridPLAY Technology
(MDPI, 2018-10-14)
The incorporation of the elderly into digital leisure has been especially driven by the development of games and applications that link the experience of play with beneficial effects for the user. Some of these benefits ...

Upper bounds for the Poincaré recurrence time in quantum mixed states
(IOP Publishing Ltd., 2017-04)
In this paper we use geometric techniques to provide upper bounds for the Poincaré recurrence time of a quantum mixed state with a discrete spectrum of energies. We obtain two types of upper bounds. One of them depends on ...
