Recent ideas for the origin and persistence of the warps commonly observed in disc galaxies have focused on cosmic infall. We present N -body simulations of an idealized form of cosmic infall onto a disc galaxy and obtain a warp that closely resembles those observed. The inner disc tilts remarkably rigidly, indicating strong cohesion due to self-gravity. The line of nodes of the warp inside R26...

The shear-warp algorithm for volume rendering is among the fastest volume rendering algorithms. It is an object-order algorithm, based on the idea of the factorization of the view matrix into a 3D shear and a 2D warp component. Thus, the compositing can be done in sheared object space, which allows the algorithm to take advantage of data locality. Although the idea of a perspective projection s...

Active appearance models (AAMs) have demonstrated great utility when being employed for non-rigid face alignment/tracking. The "simultaneous" algorithm for fitting an AAM achieves good non-rigid face registration performance, but has poor real time performance (2-3 fps). The "project-out" algorithm for fitting an AAM achieves faster than real time performance (> 200 fps) but suffers from poor g...

A way to accelerate DEM calculations on the GPUs is developed. We examined how warp divergences take place in the contact detection and the force calculations taking account of the GPU architecture. Then we showed a strategy to reduce the impact of the warp divergences on the runtime of the DEM force calculations.

In this paper we present WARPLab, a framework which allows rapid prototyping of algorithms for wireless communications by combining the ease of MATLAB with the capabilities of the Wireless Open-Acces Research Platform (WARP). The WARPLab framework provides the software necessary for easy interaction with the WARP hardware directly from the MATLAB workspace. WARPLab is unique in its capabilities...

Time warping allows users to modify timing without affecting poses. It has many applications in animation systems for motion editing, such as refining motions to meet new timing constraints or modifying the acting of animated characters. However, time warping typically requires many manual adjustments to achieve the desired results. We present a technique which simplifies this process by allowi...

It is commonly believed that Alcubierre’s warp drive works by contracting space in front of the warp bubble and expanding space behind it. We show that this expansion/contraction is but a marginal consequence of the choice made by Alcubierre, and explicitly construct a similar spacetime where no contraction/expansion occurs.

Tingle is a new digital music controller that attempts to recapture the acoustic touch and feel, and also gives new opportunities for expressive play. Tingle resembles a pin-art toy which has been made interactive through a new sensing technology, with added haptic feedback and motion control. It pushes back, vibrates, and warps the sound through the musicians nuanced input. In this article Tin...

The school works in co-operation with an Educational Clinic to which all cases of backwardness in the Elementary Schools of the City are referred. The majority of the children are suffering from emotional difficulties due in large measure to environmental causes. There is the nervous child who has fallen behind through fear of failure, the resentful child who may become delinquent, the child wi...
