The fixed-length sliding window approach is widely used in video search applications. This approach computes the similarity between a given query and each windowed sequence, and determines whether their similarity exceeds a predefined threshold. However, using the fixed window length and the predefined threshold is inflexible for detecting video copies that might have been derived by applying a...

The relationships between coping strategies, goal adjustment, and symptoms of depression and anxiety were studied in 104 HIV-positive men who have sex with men, in December 2006. The mean age of the respondents was 50 years, and almost were of Dutch nationality. On average people had known about their HIV-positive status for 10 years and the majority was on HIV-medication. The Cognitive Emotion...

The surface of a nonwetting droplet is separated from a solid surface by a continuous supply of a lubricating gas film within the apparent contact region. Under certain conditions, e.g., application of an external excitation force, the gas film thickness can decrease to a level where intermolecular forces cause the droplet to wet the surface. The thickness of the lubricating film can be measure...

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...

Lately a new generation of application domains is emerging. Such applications, heavily dynamic and interactive, include interactive multimedia applications, virtual reality worlds, digital movies and 3D animations. They deal with intensive spatio-temporal dependencies between the participating objects with motion becoming a central issue. Indeed in the aforementioned application domains, much o...

Abstract This paper reports a site-specific spatio-temporal channel model for the suburban slightly NLOS (non-line-of-sight) microcellular environment, based on the field test result of the azimuth-delay spectrum. The parameter extraction scheme of the spatio-temporal channel is briefly reviewed [1, 2], first. Then, the implementation issue of the stochastic spatio-temporal fading simulator is ...

In this contribution we present a cognitively motivated approach to an interactive assistance system for spatio-temporal planning tasks. Since mental spatial problem solving is known to be based on hierarchical representations, we argue for region-based representation structures that allow for structuring a complex spatio-temporal problem such that exploring and communicating alternative soluti...

ion for spatio-temporal analysis. Specifically, our contribution includes 1) the design of distributed programming abstraction for spatio-temporal analysis, 2) investigation of performance bottleneck for spatio-temporal analysis on large-scale camera networks, and 3) scalable mechanisms that address computation and communication overheads of state update. 4.1 Application Logic of Spatio-tempora...

We present the combination of microscopic model calculations and direct experimental evidence for complex spatio-temporal dynamics on a picosec-ond timescale in the near-eld of a broad area semiconductor laser induced by the interplay of self-focusing, diiraction, and spatial hole burning. We demonstrate the formation of migrating optical laments within the turn-on dynamics of such a laser and ...
