Two-way layout factorial experiments of spatial point pattern responses in mineral flotation
(Springer, 2021-03-25)
Factorial experiments are well-understood when the given observations are outcomes
of random variables. However, when we observe spatial point patterns in each combination
of factors cells, the methodology is much less ...
Process Model Metrics for Quality Assessment of Computer-Interpretable Guidelines in PROform
(MDPI, 2021-03-25)
Background: Clinical Practice Guidelines (CPGs) include recommendations to optimize patient care and thus have the potential to improve the quality and outcomes of healthcare. To achieve this, CPG recommendations are usually ...
Tunable telephoto: governable Fourier spectrum anamorphic scaling
(2021-02-18)
We discuss the Gaussian design of a device that controls the scale, in an anamorphic fashion, of Fraunhofer diffraction patterns. The device uses two pairs of varifocal cylindrical lenses. For spherical lenses, the optical ...
Modeling accident risk at the road level through zero-inflated negative binomial models: A case study of multiple road networks
(Elsevier, 2021-03-26)
This paper presents a case study carried out in multiple cities of the Valencian Community (Spain) to determine the effect of sociodemographic and road characteristics on traffic accident risk. The analyzes are performed ...
Smartphone Distance Estimation Based on RSSI-Fuzzy Classification Approach
(Institute of Electrical and Electronics EngineersIEEE, 2021-06-15)
Positioning people indoors has known an exponential growth in the last few years, especially thanks to Bluetooth Low Energy (BLE) technology and the Received Signal Strength Indicator (RSSI) technique. This approach is ...
High photocatalytic activity of Ag/Ag3PO4:W heterostructure formed by femtosecond laser irradiation
(Sao Paulo State University. Institute of Chemistry, 2022-04-11)
In this work, the W-doped Ag3PO4 was prepared by the chemical coprecipitation method and irradiated with a femtosecond laser (FL). The successful formation of the Ag/Ag3PO4:W heterostructure was confirmed by XRD analysis. ...
Head and eye egocentric gesture recognition for human-robot interaction using eyewear cameras
(IEEE, 2022-06-08)
Non-verbal communication plays a particularly important role in a wide range of scenarios in Human-Robot Interaction (HRI). Accordingly, this work addresses the problem of human gesture recognition. In particular, we focus ...
Comparison of Nitrogen Dioxide Predictions During a Pandemic and Non-pandemic Scenario in the City of Madrid using a Convolutional LSTM Network
(World Scientific, 2022-06-22)
Traditionally, machine learning technologies with the methods and capabilities available, combined with a geospatial dimension, can perform predictive analyzes of air quality with greater accuracy. However, air pollution ...
Testing similarity between first-order intensities of spatial point processes. A comparative study
(Taylor & Francis, 2023)
Testing whether two spatial point processes have the same spatial distribution is an important task that can be addressed from different perspectives. A Kolmogorov-Smirnov test with asymptotic calibration and a Cramer von ...
Mobile device-based Bluetooth Low Energy Database for range estimation in indoor environments
(Nature Research, 2022)
The demand to enhance distance estimation and location accuracy in a variety of Non-Line-of-Sight (NLOS) indoor environments has boosted investigation into infrastructure-less ranging and collaborative positioning approaches. ...
