Effective Spatial Data Broadcasting

2012 IEEE International Conference on Multimedia and Expo, 2012
Data broadcast is an advanced technique to realize large scalability and bandwidth utilization in a mobile computing environment. Three dimensional (3D) contents are emerging data in the data broadcast. However, traditional data broadcast did not consider 3D data to design a data schedule in a broadcast channel.

The spatial dimensions of neighborhood effects

Social Science & Medicine, 2009
In the decade or so of renewed interest in neighborhood contexts and health, significant progress has been made conceptualizing the relationships between the urban environment and public health. Applied research on the link between the environment and health remains limited by the way spatial concepts, such as "the neighborhood" or "the built ...

Sequence effects in estimating spatial location

Psychonomic Bulletin & Review, 2010
Three experiments provide evidence for a primacy effect in judgments of spatial location. Participants viewed and immediately estimated a series of spatial locations that were serially ordered from left to right or from right to left. In a subsequent block, they judged the rightmost, leftmost, and center of the distribution or were shown dots at those ...

An oblique effect of spatial summation

Vision Research, 1983
Contrast thresholds for sinewave gratings were measured as a function of the number of cycles in the grating for two different orientations and three spatial frequencies. At high spatial frequencies, where an oblique effect of contrast sensitivity was demonstrated, there was a greater increase in contrast sensitivity as a function of the number of ...

Spatial effects

Abstract This chapter examines spatial effects in mathematical biology, introducing partial differential equations to model changes over time and space. It begins with the diffusion equation, which can model how substances and populations move randomly, and extends to the classical Fisher–KPP reaction–diffusion model which exhibits ...

Spatial AC Josephson effect

Physics Letters A, 1975
Abstract Investigating the current threshold in the mixed state of superconductors basing on the Ginzburg-Landau theory, we find that the threshold is determined by a mechanism analogous to the Josephson effect. An experimental evidence of this phenomenon is presented.

Covert attention effects on spatial resolution

2009
First, we review the characteristics of endogenous (sustained) and exogenous (transient) spatial covert attention. Then we examine the effects of these two types of attention on spatial resolution in a variety of tasks, such as acuity, visual search, and texture segmentation.

Effects of Spatial Discretization

2015
In this chapter we consider what can happen when we try to compute a singular solution of the critical or supercritical NLS with a naive finite-difference scheme.

Effects of spatial extent

1992
The study of interactions between nutrients and food webs is a complex matter even without taking into account the additional effects of movement in spatially heterogeneous landscapes. However, an understanding of the effects of the additional complexity resulting from spatial extent and heterogeneity is vital for understanding ecosystems.
