This study examines the entanglement of affects that occurred during a short episode at science museum. The involved small number children and teacher who had come to museum in context school field trip. It took place inside an exhibit called ‘Hmong House’, which reproduced various components traditional house Hmong people. A key aim this paper is trace, via microethnographic analysis brief vid...

Abstract Dams are built to store the water flowing from upstream downstream. Sedimentation and siltation some of major problems affecting storage capacity dams. For effective management, bathymetric topographic data used assess this challenge. In Mambila Plateau Taraba, Nigeria, Tunga Dam is a multifunctional reservoir that serves as small hydropower, irrigation domestic use dam. Nonetheless, i...

We argue for space-time partitioning (STP) in manycore operating systems. STP divides resources such as cores, cache, and network bandwidth amongst interacting software components. Components are given unrestricted access to their resources and may schedule them in an application-specific fashion, which is critical for good parallel application performance. Components communicate via messages, ...

A generalized version of a well-known problem of D. G. Kendall states that the zero cell of a stationary Poisson hyperplane tessellation in Rd , under the condition that it has large volume, approximates with high probability a certain definite shape, which is determined by the directional distribution of the underlying hyperplane process. This result is extended here to typical kfaces of the t...

Efficient ray tracing of subdivision surfaces is an important problem in production rendering, and for interactive applications in the near future. The current hardware trends for both CPUs and GPUs suggest that compute power is outpacing bandwidth. Despite this, current approaches for ray tracing subdivision surfaces favor geometry caches or full pre-tessellation. We demonstrate that directly ...

DTMs derived from digitized contour lines often suffer from limited quality. The quality can be enhanced by automatically extracting skeleton lines from the contours prior to triangulation and subsequent interpolation. A hybrid set of raster and vector techniques is used for skeleton extraction and TIN generation, including distance transformation, Dirichlet tessellation, thinning, gap filling,...

A two part probabilistic model for polycrystalline microstructures is described. The model utilizes a Poisson–Voronoi tessellation for the grain geometry and a vector random field model for the crystallographic orientation. The grain geometry model is calibrated to experimental data through the intensity of the Poisson point field underlying the Poisson–Voronoi tessellation and the orientation ...
