Long-Term Analyses of the Rate of Perceived Exertion as an Indicator of Intensity in Women’s Basketball during a Relegation Play-off
(MDPI, 2022-11)
Knowledge of internal load is essential to understand the effect of training and competition on athletes. The aim of this study was to analyse the validity of the rate of perceived exertion (RPE) scale as an indicator of ...
Lp-calculus Approach to the Random Autonomous Linear Differential Equation with Discrete Delay
(Springer Nature Switzerland AG, 2019-06-19)
In this paper, we provide a full probabilistic study of the random autonomous linear differential equation with discrete delay τ > 0:
x
(t) = ax(t) + bx(t − τ ), t ≥ 0, with initial condition x(t) = g(t),
−τ ≤ t ≤ 0. ...
Improving the approximation of the probability density function of random nonautonomous logistic-type differential equations
(John Wiley & Sons, Ltd., 2019-08-16)
In this paper, we address the problem of approximating the probability density function of the following random logistic differential equation: P
′
(t, 𝜔�) =
A(t, 𝜔�)(1 − P(t, 𝜔�))P(t, 𝜔�), t ∈ [t0, T], P(t0, 𝜔�) ...
Multivariate Kalman filtering for spatio-temporal processes
(Springer, 2022)
An increasing interest in models for multivariate spatio-temporal processes has been noted in the last years. Some of these models are very flexible and can capture both marginal and cross spatial associations amongst the ...
Uncertainty quantification for random parabolic equations with nonhomogeneous boundary conditions on a bounded domain via the approximation of the probability density function
(John Wiley & Sons, Ltd., 2018-11-14)
This paper deals with the randomized heat equation defined on a general bounded interval [L1, L2] and with nonhomogeneous boundary conditions. The solution is a stochastic process that can be related, via changes of variable, ...
Identification of Latent Topics in Patients Surviving COVID-19 in Mexico
(IEEE, 2023-01-11)
With the outbreak of the SARS-CoV-2 o COVID-19 pandemic, multiple studies of risk factors and their influence on patient deaths have been developed. However, little attention is often paid to analyzing patients in risk ...
Structural Complexity and Informational Transfer in Spatial Log-Gaussian Cox Processes
(MDPI, 2021-08-31)
The doubly stochastic mechanism generating the realizations of spatial log-Gaussian
Cox processes is empirically assessed in terms of generalized entropy, divergence and complexity
measures. The aim is to characterize ...
Time-expanded φOTDR using low-frequency electronics
(Optica Publishing Group, 2023-01)
Time expanded phase-sensitive optical time-domain reflectometry (TE-φOTDR) is a
recently reported technique for distributed optical fiber sensing based on the interference of two
mutually coherent optical frequency combs. ...
New Cluster Selection and Fine-grained Search for k-Means Clustering and Wi-Fi Fingerprinting
(IEEE, 2020-06-02)
Wi-Fi fingerprinting is a popular technique for Indoor Positioning Systems (IPSs) thanks to its low complexity and the ubiquity of WLAN infrastructures. However, this technique may present scalability issues when the ...
Far-field perfect imaging with time-modulated gratings
(American Physical Society, 2022-06-22)
We study the capabilities of time-modulated diffraction gratings as imaging devices. It is shown that a time-dependent but transversally homogeneous slab can be used to make a perfect image of an object in the far-field, ...
