Direct lightweight temporal compression for wearable sensor data
(IEEE, 2021-02-01)
Emerging technologies enable massive deployment of wireless sensor networks across many industries. Internet of Things (IoT) devices are often deployed in critical infrastructure or health monitoring and require fast ...
Complex shaping of the depth of focus
(Optical Society of America, 2020)
In this manuscript an exact solution to the inverse problem of axial beam shaping along the focus of a convergent lens is found. This allows to extend, within the framework of the scalar theory of diffraction, the mathematical ...
Remotely Sensed Data Fusion for Spatiotemporal Geostatistical Analysis of Forest Fire Hazard
(MDPI, 2020)
Forest fires are a natural phenomenon which might have severe implications on naturaland anthropogenic ecosystems. Future projections predict that, under a climate change environment,the fire season would be lengthier with ...
Multi-Slot BLE Raw Database for Accurate Positioning in Mixed Indoor/Outdoor Environments
(MDPI, 2020-07-30)
The technologies and sensors embedded in smartphones have contributed to the spread of
disruptive applications built on top of Location Based Services (LBSs). Among them, Bluetooth Low
Energy (BLE) has been widely adopted ...
A game development environment to make 2D games
(Universitat de Girona, 2020)
The creation of video games involves multidisciplinary processes that are not accessible to the general public. Currently, the development environments are very powerful tools, but they also require an advanced technical ...
Improved perception of ceramic molds through augmented reality
(Springer Nature, 2022-05-23)
Augmented Reality techniques allow the user to visualize part of the real world through a display device by incorporating graphical information into the existing physical information. In this sense, it is important to know ...
On the Role of Geometric Constraints to Support Design Intent Communication and Model Reusability
(CAD Solutions, 2020)
The assurance of model quality in parametric CAD implies that designers must build models that facilitate reuse while retaining their design intent when modified. In this context, a suitable selection of geometric constraints ...
A lower bound for the area of Plateau foams
(Springer, 2020-04-07)
Real foams can be viewed as geometrically well-organized dispersions of more or less spherical bubbles in a liquid. When the foam is so drained that the liquid content significantly decreases, the bubbles become polyhedral-like ...
Air Quality Prediction in Smart Cities Using Machine Learning Technologies Based on Sensor Data: A Review
(MDPI, 2020-04-01)
The influence of machine learning technologies is rapidly increasing and penetrating almost in every field, and air pollution prediction is not being excluded from those fields. This paper covers the revision of the studies ...
Dynamics of Fractional Vortex Beams at Fraunhofer Diffraction Zone
(MDPI, 2022-07-09)
Fractional vortex beams (FVBs) possess unique topological properties that are manifested in the vortex distribution. However, there are still discrepancies in the value of the vortex strength of FVBs at the far field. In ...
