We used the event-related potential (ERP) approach combined with a subtraction technique to explore the timecourse of activation of semantic and phonological representations in the picture-word interference paradigm. Subjects were exposed to to-be-named pictures superimposed on to-be-ignored semantically related, phonologically related, or unrelated words, and distinct ERP waveforms were genera...

In this work, we address the problem of spatio-temporal action detection in temporally untrimmed videos. It is an important and challenging task as finding accurate human actions in both temporal and spatial space is important for analyzing large-scale video data. To tackle this problem, we propose a cascade proposal and location anticipation (CPLA) model for frame-level action detection. There...

In the present computing environment, access control decisions are often based on contextual information like the location of users and objects as well as the time of making an access request. Several variants of Role based Access Control (RBAC) have recently been proposed that support spatio-temporal policy specifications. However, unlike the administrative models available for RBAC, there is ...

Schema versioning provides a mechanism for handling change in the structure of database systems and has been investigated widely, both in the context of static and temporal databases. With the growing interest in spatial and spatio-temporal data as well as the mechanisms for holding such data, the spatial context within which data is formatted also becomes an issue. This paper presents a genera...

We study spatio-temporal bursting in a three-scale reaction diffusion equation organized by the winged cusp singularity. For large time-scale separation the model exhibits traveling bursts, whereas for large space-scale separation the model exhibits standing bursts. Both behaviors exhibit a common singular skeleton, whose geometry is fully determined by persistent bifurcation diagrams of the wi...

During the COVID-19 pandemic, access to space has been strictly regulated and restricted. Many of us feel acutely disconnected from our relationships, while at same time new forms (virtual) intimacies have become ubiquitous. In pandemic present, nearly all interpersonal relations are now characterised by a double absence that is concrete material, also emotional felt. This article offers theore...

In this paper, a novel structure is proposed for human activity modeling using time sequential spatio-temporal texture primitives. Gabor filters, which are proven to be robust 2D texture representation tools, are extended to 3D domain to capture spatio-temporal texture features. A well known filtering algorithm and an unsupervised clustering algorithm, the Genetic Chromodynamics, are combined t...

The integrated management of both spatial and temporal components of information is crucial in order to extract significant knowledge from datasets concerning phenomena of interest to a large variety of applications. Moreover, multigranularity, i.e., the capability of representing information at different levels of detail, enhances the data modelling flexibility and improves the analysis of inf...

This research aims to obtain 3D information by using spatio-temporal analysis of omni images for outdoor navigation and map-making in the intelligent transportation system (ITS) application. Two types of omnidirectional cameras are employed to make a spatio-temporal volume, which is a sequence of omni images stacked in the spatio-temporal space. For the spatio-temporal analysis of an omni image...
