This study introduces a video compression method that uses spatio – temporal lifting based algorithms to compress the video signals. The temporal correlation of consecutive frames causes temporal redundancies which are subject to lifting-like motion predictive compression. Moreover, the spatial correlation between neighbouring pixels of the same frame is subject to intra-frame wavelet compressi...

We define a new notion of satisfaction of a temporal logic formula φ by a behavior w. This notion, denoted by (w, t, t′) |= φ, is characterized by two time parameters: the position t from which satisfaction is considered, and the end of the (finite) behavior t′ which indicates how much do we know about the behavior. We define this notion in dense time where φ is a formula in the future fragment...

We conduct a panel analysis quantifying the degree to which the mixture of low-, middleand high-income males in the neighbourhood affect the subsequent labour income of individuals, and test the degree to which these effects vary by timing (lagging up to three years) duration (one to four years), and cumulative amount of exposure and to what extent these effects are persistent. We employ a fixe...

OBJECTIVE The purpose of this study was to investigate how young normal-hearing (YNH) and elderly hearing-impaired (EHI) listeners make use of redundant speech-like cues when classifying nonspeech sounds having multiple stimulus dimensions. DESIGN A total of four experiments were conducted with 10 to 12 listeners per group in each experiment. There were 27 stimuli, making use of all possible ...

Data from 4,855 respondents to the Panel Study of Income Dynamics were used to examine spatial and temporal dimensions of the effect of neighborhood poverty on teenage premarital childbearing. Although high poverty in the immediate neighborhood increased the risk of becoming an unmarried parent, high poverty in surrounding neighborhoods reduced this risk. The effect of local neighborhood povert...

This paper presents how hot spot detection methods can be extended to allow for temporal dimensions. Major concerns are how temporal dimension is incorporated into the framework of point pattern analysis, while maintaining the capability of multi-scale analysis. The study elaborates on expanding the scope of (space) K function in order to count time in the analysis. With the explicit treatment ...

The increment of spatial-temporal data (STD) collected in many domain areas, including bioinformatics, engineering, medicine, environment, telecommunication, computer vision and many more has leads towards the emergent of information technology initiatives that facilitate the knowledge acquisition, organization and dissemination among research community. The initiatives include but not exhaust ...

The presented data model is a novel approach for integrating temporal concepts into a multimedia database system. Multimedia objects are extended with the traditional time dimensions valid time and transaction time. In addition a new time dimension specifically tailored for multimedia data types is presented with semantics that are completely orthogonal to the already established time dimension...
