abstract: one of the most visited & important spaces in different countries by tourist are urban areas. the old tehran which major part is located in district 12 is historical showcase of the capital, but, its hiidden cultural attraction is not used as it should be. this thesis occasionally engage in studying the efficacy of correct installation of travel guide boards in welfare & easily acc...
A theoretical model is developed to describe the interferometric coherency between pairs of SAR images of rough soil surfaces. The model is derived using a dyadic form for surface reflectivity in the Kirchhoff approximation. This permits the combination of Kirchhoff theory and spotlight synthetic aperture radar (SAR) image formation theory. The resulting model is used to describe the interferom...
of the Thesis Optimizing Cache Behavior of Ray-Driven Volume Rendering Using Space-Filling Curves by Oleg Mishchenko Master of Science in Computer Science Stony Brook University 2006 We study the cache behavior of space-filling curves in the context of volume rendering with raycasting. An efficient bit-oriented algorithm for 3D Hilbert curve traversal is also proposed. We find that data organiz...
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
[1] We show that the spatial coherency of the ambient seismic field can be used for attenuation tomography in the western United States. We evaluate the real portion of the spatial coherency with an elastic geometric spreading term (a Bessel function) and a distance dependent decay (an attenuation coefficient). In order to invert the spatial coherency, a weight stack inversion technique is appl...
Despite outstanding successes of the state-of-the-art clustering algorithms, many of them still suffer from shortcomings. Mainly, these algorithms do not capture coherency and homogeneity of clusters simultaneously. We show that some of the best performing spectral as well as hierarchical clustering algorithms can lead to incorrect clustering when the data is comprised of clusters with differen...
Multiprocessor systems-on-chip (MPSoC) with distributed shared memory and caches are flexible when it comes to inter-processor communication but require an efficient memory consistency and cache coherency solution. In this paper we present a novel consistency model, streaming consistency, for the streaming domain in which tasks communicate through circular buffers. The model allows more reorder...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
In shared-memory multiprocessor systems, the local caches which are used to tolerate the performance gap between processor and memory cause additional bus transactions to maintain the coherency of shared data. Especially, coherency misses and data traffic due to spatial locality and false sharing have a singificant effect on the system performance. In this approach, an adaptive cache coherence ...
A major problem considering parallel computing is maintaining memory consistency and coherency, and ensuring ownership and access rights. These problems mainly arise from the fact that memory in parallel and distributed systems is still managed locally, e.g. using a combination of shared-busand directory-based approaches. As a result, such setups do not scale well with system size and are espec...
