The goal of this research is recognition of species of pollution and a rough estimate of rate of transmitted pollution through northern Iran rivers to Caspian sea. Sampling from 3stations up-river, mid-river, and down-river in Lavij rood, Gland rood, and Sabze rood in a 6 month period from 2008/5/22 to 2008/11/22 coincides with warm, low rain, cold and rainy seasons and parameters as temperatur...

This paper is a review of the block matching algorithms used for motion estimation in video compression. It implements and compares several different types of block matching algorithms that ranges from the very basic Exhaustive Search to the recent fast adaptive algorithms like Adaptive Rood pattern Search Algorithm. The algorithms that are evaluated in this paper are widely accepted by the vid...

Palmar supracondylar lysis of the third metacarpus, enthesophytes on the proximal sesamoid bones, proximal dorsal P1 fragments in the hind fetlocks, and dorsal medial intercarpal joint disease in Thoroughbred yearlings are associated with decreased likelihood of starting at least one race during the 2or 3-year-old years. Authors’ addresses: Equine Orthopaedic Research Laboratory, College of Vet...

We propose a fast motion estimation (FME) algorithm that performs comparably to the full search while having improved performance when compared to the best FME methods that are recommended for the JVT/H.264 standard despite having a much lower computational complexity than these methods. Our algorithm, called the predictive and adaptive rood pattern with large motion search, incorporates motion...

We present a Lagrangian particle/panel method for geophysical fluid flow described by the barotropic vorticity equations on a rotating sphere. The particles carry vorticity and the panels are used in discretizing the Biot-Savart integral for the velocity. Adaptive panel refinement and a new Lagrangian remeshing scheme are applied to reduce the computational cost and maintain accuracy as the flo...

Background. For X a smooth scheme over ~, K.t(X; 2g/{") is isomorphic to the usual rood(" topological K-theory of X as a complex manifold ([6]). In this case, Theorem 1 essentially answers a question of Fulton, [9], w 5. For many such X the mapp: Ko(X)~K~ot(X) cannot be a surjection, as non-trivial Hodge conditions on the Chern classes prevent some topological bundles from being stably algebrai...

Management of seizure activity in the neonatal foal presents a number of challenges. Control of neurological dysfunction and prevention of secondary physical injury is necessary in the first instance. Diagnosis of any underlying medical conditions must occur. Wide-ranging knowledge of the underlying cerebral pathology is essential when formulating a treatment plan. The relatively limited knowle...

the agriculture sector is the largest water consumer in arid and semi-arid areas. so water scarcity has an important effect on this section. drought as one of the most important factors in making crisis in zayanderud river basin (zrb) has a deep effect on the agriculture sector. this study evaluates the drought effects on irrigation land and farmers profit on the east of zrb by using spi and cb...
