Recent advances in mobile technologies led to new spatially-and context-aware definitions of relevance. In this paper, we aim to develop the conceptual framework suggested by Mizzaro (1998) further, in order to improve the characterization and classification of current and future concepts of relevance. We formalise two new dimension of relevance. The first dimension emphasizes the spatio-tempor...

Phenological changes within a growth season were investigated in two grazed, seminatural grasslands in southern Sweden. On four occasions during the growth season, two independent observers recorded plant frequency and percentage cover. The vegetation data sets were analysed with ordination methods. The temporal changes were highly significant, but accounted for only a small part of the total v...

Conventional metrics used to quantify signals in noise/hearing research rely primarily on time-averaged energy and spectral analyses. Such metrics, while appropriate for Gaussian-distributed waveforms, are of limited value in the more complex sound environments encountered in industrial/military settings that have nonGaussian and nonstationary-distributed waveforms. Recent research has shown th...

We consider the distribution of economic activity within a country in light of three leading theories—increasing returns, random growth, and locational fundamentals. To do so, we examine the distribution of regional population in Japan from the Stone Age to the modern era. We also consider the Allied bombing of Japanese cities in WWII as a shock to relative city sizes. Our results support a hyb...

The mechanisms of interdecadal changes of El NifioSouthern Oscillation (ENSO) modes are examined through an eigen analysis of a simple coupled ocean-atmosphere model. It is shown that the observed interdecadal climate shift can effectively modify the strength of two major coupled feedbacks for the ENSO mode, namely, the zonal advection and thermocline feedbacks. These modifications lead to quan...

Automatically understanding human actions using motion trajectories derived from video sequences is a very challenging problem. Since an action takes place in 3-D, and is projected on 2-D image, depending on the viewpoint of the camera, the projected 2-D trajectory may vary. Therefore, the same action may have very different trajectories, and trajectories of different actions may look the same....

An articulatory study was conducted to explore effects of prosodic boundary and syllable structure on temporal realizations of /ma/ in C♯V vs. ♯CV in Korean (where ‘♯’ denotes an Intonational Phrase or a Word boundary). The vocalic gesture underwent boundary-induced lengthening more in C♯V than in ♯CV, implying that the boundary effect is largely localized to the initial element whether consona...

This paper discusses a prototype of a temporal pattern predictor, which was built on specifications derived from the descriptions of the “Ergotrix” temporal memory network in Valentino Braitenberg’s “Vehicles” (Braitenberg, 1984). The prototype was developed as a component for a control architecture for virtual characters.

Moving objects database (MOD) contains the information (locations and times) of moving objects, e.g., taxicabs, trucks, airplanes, polar bears, etc. This information continuously changes and thus needs to be updated frequently in order to maintain the accuracy and usefulness of the information. This paper presents a fuzzy-timing Petri net model for updating a MOD and a method for estimating the...
