In computing field, demand of speed is going beyond the limit, thus to satisfy the high-end needs, multi-core processors are playing its crucial role. As far as multicore is concerned, there are few difficulties to be optimized for the promising future processor infrastructure, SoC(System on chip) based processor is being replaced with NoC(Network on Chip). NoC is expected to overcome the limit...

Space time cube representation is an information visualization technique where spatiotemporal data points are mapped into a cube. Fast and correct analysis of such information is important in for instance geospatial and social visualization applications. Information visualization researchers have previously argued that space time cube representation is beneficial in revealing complex spatiotemp...

abstract the urmia lake as an important water body in the northwest of iran, recently is faced with a critical level reduction, which makes it important to evaluate the causes. in this regard understanding of the lake's behavior and assessing effect of tele-connections on lake level oscillations is necessary. this subject constructs objective of the present paper that applies the spectral analy...

The objective evaluation of 2D-shape estimation results for moving objects in a video sequence is still an open problem. First approaches in the literature evaluate the spatial accuracy and the temporal coherency of the estimated 2D object shape. Thereby, it is not distinguished between several estimation errors located around the object contour and a few, but larger, estimation errors. Both ca...

Standard stacking procedures are based on the combination of many scalar traces, and can exploit the coherency of arrivals between traces using non-linear methods. Such stacks can be used with some success for three-component data but do not exploit the vector character of the seismic wave¢eld. A set of stacking methods are introduced to work directly with three-component data and include inter...

This paper represents a study on land-cover classification using different polarimetric SAR features. The experiment is carried out using Cand L-band fully polarimetric EMISAR data acquired on July 5 and 6, 1995 over an agricultural area in Fjärdhundra, near Uppsala, Sweden. The polarimetric features investigated are coherency matrix, intensity of both Cand L-band SAR, and Cloud decomposition p...

Database Sharing (DB-sharing) refers to a general approach for building a distributed high performance transaction system. The nodes of a DB-sharing system are locally coupled via a high-speed interconnect and share a common database at the disk level. This is also known as a “shared dis~ approach. We compare database sharing with the database partitioning (shared nothing) approach and discuss ...

The concept of coherency loss is proposed to understand wrinkle branching as a pathway toward hierarchical wrinkling pattern formation in a compressed film-substrate system with gradient stiffness of the film or substrate. A simple model indicates that the wrinkle branching arises when the characteristic length of the stiffness inhomogeneity zone is larger than the coherency persistent length, ...

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...

We investigate the manual and automatic annotation of PDTB discourse relations in student essays, a novel domain that is not only learning-based and argumentative, but also noisy with surface errors and deeper coherency issues. We discuss methodological complexities it poses for the task. We present descriptive statistics and compare relation distributions in related corpora. We compare automat...
