Entomological study of Phlebotomine Sand flies in Maceió (Brazil): 2011-2020 analysis [PDF]

Brazilian Journal of Biology
This study investigated the spatiotemporal distribution of phlebotomine sand flies in Maceió, Alagoas, Brazil, over ten years (2011–2020). Maceió, the capital of the State of Alagoas, has a tropical climate with significant seasonal rainfall disparities.

Automated Analysis Using a Bayesian Functional Mixed-Effects Model With Gaussian Process Responses for Wavelet Spectra of Spatiotemporal Colonic Manometry Signals

Frontiers in Physiology, 2021
Manual analysis of human high-resolution colonic manometry data is time consuming, non-standardized and subject to laboratory bias. In this article we present a technique for spectral analysis and statistical inference of quasiperiodic spatiotemporal ...

A semantic content analysis model for sports video based on perception concepts and finite state machines [PDF]

, 2007
In automatic video content analysis domain, the key challenges are how to recognize important objects and how to model the spatiotemporal relationships between them. In this paper we propose a semantic content analysis model based on Perception Concepts (

Common SpatioTemporal Pattern Analysis [PDF]

, 2010
In this work we present a method for the estimation of a rank-one pattern living in two heterogeneous spaces, when observed through a mixture in multiple observation sets. Using a well chosen representation for an observed set of second order tensors (matrices), a singular value decomposition of the set structure yields an accurate estimate under some ...

ST-CORAbico: A Spatiotemporal Object-Based Bias Correction Method for Storm Prediction Detected by Satellite

Remote Sensing, 2020
Advances in near real-time rainstorm prediction using remote sensing have offered important opportunities for effective disaster management. However, this information is subject to several sources of systematic errors that need to be corrected.

Recognizing Events in Spatiotemporal Soccer Data

Applied Sciences, 2020
Spatiotemporal datasets based on player tracking are widely used in sports analytics research. Common research tasks often require the analysis of game events, such as passes, fouls, tackles, and shots on goal. However, spatiotemporal datasets usually do

Flow-directed PCA for monitoring networks [PDF]

, 2017
Measurements recorded over monitoring networks often possess spatial and temporal correlation inducing redundancies in the information provided. For river water quality monitoring in particular, flow-connected sites may likely provide similar information.

Spatiotemporal analysis of brightness induction

Vision Research, 2011
Brightness induction refers to a class of visual illusions in which the perceived intensity of a region of space is influenced by the luminance of surrounding regions. These illusions are significant because they provide insight into the neural organization of the visual system.
