2016 arXiv   pre-print
We show that such transition features are highly predictive of place attributes.  ...  Our method, STEPS, learns from aggregated sequences of place visits.  ...  We introduce STEPS, Spacio-TEmporal analysis of Place attributeS, which learns from trajectory patterns of patrons' visits to the place.  ...

Topographic ERP Analyses: A Step-by-Step Tutorial Review

Micah M. Murray, Denis Brunet, Christoph M. Michel
2008 Brain Topography  
For each step of these analyses, we provide the reader with both a conceptual and mathematical description of how the analysis is carried out, what it yields, and how to interpret its statistical outcome  ...  In these and other ways these topographic analysis methods allow the experimenter to glean additional information and neurophysiologic interpretability beyond what is available from canonical waveform  ...  The spatio-temporal analysis methods that we summarize here can render a far more complete and informative interpretability without any a priori bias on certain time periods or scalp locations.  ...

2014 Movement Ecology  
SSFs compare environmental attributes of observed steps (the linear segment between two consecutive observations of position) with alternative random steps taken from the same starting point.  ...  SSFs also have the potential to depict resource selection at multiple spatial and temporal scales.  ...  The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.  ...

A Two-Step Clustering Approach to Extract Locations from Individual GPS Trajectory Data

Zhongliang Fu, Zongshun Tian, Yanqing Xu, Changjian Qiao
2016 ISPRS International Journal of Geo-Information  
The experimental results show that the spatio-temporal clustering algorithm outperformed traditional extraction algorithms.  ...  The spatio-temporal clustering algorithm can largely avoid the problems of signal loss and data drift. It can also reduce the impact of segmentation found in the literature [3] .  ...  Through the analysis of a large amount of data, Gonzalez et al. [1] found that human trajectories show a high degree of temporal and spatial regularity.  ...

Steps Towards a Precautionary Risk Governance of SPAGE Technologies Including Gene-Drives [chapter]

Arnim von Gleich
2020 Gene Drives at Tipping Points  
At least, an extreme extension of the spatio-temporal range of GMOs is addressed as an insight-limiting aspect, but as a way out, reference is again only made to ex-post observation via Post Market Environmental  ...  On the other hand, emphasis is placed on the spatial and temporal decoupling of emission and possible effect (cf.  ...

Dynamic TOPMODEL: A new implementation in R and its sensitivity to time and space steps

Peter Metcalfe, Keith Beven, Jim Freer
2015 Environmental Modelling & Software  
The paper focuses on the 20 robustness of the predicted output variables to changes in the time and space discretisations. 21  ...  Furthermore, the practical limits on the accuracy and spatio-27 temporal resolution of catchment data lays open to question whether it could ever contain sufficient information to 28 justify such complex  ...  Shown are the absolute difference of the predicted discharges within each trial from those predicted using a time step of 5 minutes.  ...

Clonal building, simple growth rules and phylloclimate as key steps to develop functional–structural seagrass models

FG Brun, JJ Vergara, G Peralta, MP García-Sánchez, I Hernández, JL Pérez-Lloréns
2006 Marine Ecology Progress Series  
This result was mainly attributable to a lack of densitydependence phenomena in the model assumptions, revealing the importance of such phenomena in structuring seagrass populations.  ...  Inter-and intraspecific variability in plant morphology and meadow attributes was simulated, and the results yielded by the model were compared with an existing large data set recorded for both species  ...  Furthermore, the combination of spatio-temporal gradients in resource availability (light, nutrients, current, space, etc.)  ...

Walk to me when I smile, step back when I'm angry: emotional faces modulate whole-body approach–avoidance behaviors

John F. Stins, Karin Roelofs, Jody Villan, Karen Kooijman, Muriel A. Hagenaars, Peter J. Beek
2011 Experimental Brain Research  
Posturographic parameters of the steps related to automatic stimulus evaluation, step initiation (reaction time), and step execution were determined and analyzed as a function of stimulus valence and stimulus-response  ...  The main result was that participants needed more time to initiate a forward step towards an angry face than towards a smiling face (which is evidence of a congruency effect), but with backward steps,  ...  There are a number of relevant spatio-temporal parameters from the COP profile associated with the steps.  ...

2017 arXiv   pre-print
This has consequences in the so-called "signal-to-symbol barrier" problem, as well as in the analysis and design of active sensing systems.  ...  Other approaches include a variety of "spatio-temporal interest point detectors" [194, 104] or other aggregated spatio-temporal statistics [45] . 87 If we are interested in visual decisions involving  ...  This issue is very complex and delicate, and a few small steps towards a complete analysis are described in Section B.3.  ...
