Evaluating stereo and motion cues for visualizing information nets in three dimensions
- ACM Transactions on Graphics
, 1996
"... This article concerns the benefits of presenting abstract data in 3D. Two experiments show that motion cues combined with stereo viewing can substantially increase the size of tbe graph that can be perceived. The first experiment was designed to provide quantitative measurements of how much more (or ..."

Motion Opponency in Visual Cortex
- Journal of Neuroscience
, 1999
"... ion; visual motion perception; motion opponency; vision; visual cortex Computational theories of visual motion perception typically include a motion opponent stage in which, for example, the response of a hypothetical leftward-selective neuron is subtracted from that of a rightward-selective neuron ..."

-selective neuron to yield a neuronal signal for net rightward motion (van Santen and Sperling, 1984, 1985; Qian et al., 1994b; Adelson and Bergen, 1985; Simoncelli and Heeger, 1998). The importance of opponent mechanisms for motion perception is supported by a number of perceptual studies (Levinson and Sekuler
Coil sensitivity encoding for fast MRI. In:
- Proceedings of the ISMRM 6th Annual Meeting,
, 1998
"... New theoretical and practical concepts are presented for considerably enhancing the performance of magnetic resonance imaging (MRI) by means of arrays of multiple receiver coils. Sensitivity encoding (SENSE) is based on the fact that receiver sensitivity generally has an encoding effect complementa ..."

The effects of non-uniform k-space weighting due to relaxation shall be neglected in the scope of this work. From the linearity
Maintaining Nets and Net Trees under Incremental Motion ⋆
"... Abstract. The problem of maintaining geometric structures for points in motion has been well studied over the years. Much theoretical work to date has been based on the assumption that point motion is continuous and predictable, but in practice, motion is typically presented incrementally in discret ..."

of certificates, which guarantee the structure’s correctness. The other checks that the motion over time satisfies these certificates and notifies the first agent of any violations. We present efficient online algorithms for maintaining both nets and net trees for a point set undergoing incremental motion in a
Transparent Motion Perception as Detection of Unbalanced Motion Signals
"... Our visual system can solve the difficult problem of representing multiple motions in the same part of the visual space, the motion transparency problem. We investigated the conditions under which transparent motion perception occurs through psychophysical observations, using a series of visual disp ..."

ALARM-NET: Wireless sensor networks for assisted-living and residential monitoring
, 2006
"... We describe ALARM-NET, a wireless sensor network for assisted-living and residential monitoring. It integrates environmental and physiological sensors in a scalable, heterogeneous architecture. A query protocol allows real-time collection and processing of sensor data by user interfaces and back-end ..."

Customized infrared motion and dust sensors, and integrated temperature, light, pulse, and blood oxygenation sensors are present. Software components include: TinyOS query
Multiple Camera Tracking of Interacting and Occluded Human Motion
- Proceedings of the IEEE
, 2001
"... We propose a distributed, real-time computing platform for tracking multiple interacting persons in motion. To combat the negative effects of occlusion and articulated motion we use a multi-view implementation, where each view is first independently processed on a dedicated processor. This monocular ..."

Controlling vortex motion and vortex kinetic friction
, 2006
"... We summarize some recent results of vortex motion control and vortex kinetic friction. (1) We describe a device [J.E. Villegas, S. Savel’ev, F. Nori, E.M. Gonzalez, J.V. Anguita, R. Garcìa, J.L. Vicent, Science 302 (2003) 1188] that can easily control the motion of flux quanta in a Niobium supercond ..."

Even though the input ac current has zero average, the resulting net motion of the vortices can be directed along either one direction, the opposite direction, or producing zero net motion. We also consider layered strongly anisotropic
