JPEG is one of the most widely used image compression method, but it causes annoying blocking artifacts at low bit-rates. Sparse representation is an efficient technique which can solve many inverse problems in image processing applications such as denoising and deblocking. In this paper, a post-processing method is proposed for reducing JPEG blocking effects via sparse representation. In this ...

The approaches to conformal and superconformal deposition developed by Abelson Girolami for a low-temperature, low-pressure chemical vapor (CVD) setting relevant electronic materials in micrometer or submicrometer scale vias trenches, are tested here high-temperature, moderate pressure CVD hard coatings millimeter-scale trenches. Conformal of polycrystalline silicon carbide (SiC) can be accompl...

abstract this research attempts to investigate the role of the blocking systems in surface cyclogenesis over eastern mediterranean sea; but particular attention is focused on the flood of iran during march 2000 over western states of iran as: hamadan, ilam, lorestan, kermanshah, kurdestan, zanjan, ghazvin.the data used for this research includes upper level and mean sea level pressure charts ev...

We consider two variants of a two-station tandem network with blocking. In both variants the first server ceases to work when the queue length at the second station hits a ‘blocking threshold.’ In addition, in variant 2 the first server decreases its service rate when the second queue exceeds a ‘slow-down threshold,’ which is smaller than the blocking level. In both variants the arrival process...

Inferences from randomized experiments can be improved by blocking: assigning treatment in fixed proportions within groups of similar units. However, the use of the method is limited by the difficulty in deriving these groups. Current blocking methods are restricted to special cases or run in exponential time; are not sensitive to clustering of data points; and are often heuristic, providing an...

Mitotic blocking agents, colchicine or Velban, were used to estimate cycle times of spleen cells which release hemolysin for sheep erythrocytes (plaque-forming cells). The cells were obtained either from rats immunized with sheep erythrocytes or from cultures of mouse spleen cells immunized in vitro with the same antigen. 2, 3, or 4 days after immunization, animals or cell cultures were treated...

The zero-temperature Glauber dynamics is used to investigate the persistence probability P (t) in the Potts model with Q = 3, 4, 5, 7, 9, 12, 24, 64, 128, 256, 512, 1024, 4096, 16384,..., 230 states on directed and undirected Barabási-Albert networks and Erdös-Rényi random graphs. In this model it is found that P (t) decays exponentially to zero in short times for directed and undirected ErdösR...

The present paper extends the so-called Effective Process Time (EPT) approach to single server flowlines with finite buffers and blocking. The power of the EPT approach is that it quantifies variability in workstation process times without the need to identify each of the contributing disturbances, and that it directly provides an algorithm for the actual computation of EPTs. It is shown that E...

When scheduling a mixed workload of hard and soft(or rm) deadline tasks, we should always guarantee the executions of hard deadline tasks. The priority inversion is one of the problems which may prevent such guarantee for hard deadline tasks. The Priority Ceiling Protocol(PCP) could be a solution to the priority inversion problem. However, the sigle blocking property of PCP is sometimes very re...

Previous studies have shown that symmetric tetraalkylammonium ions affect, in a voltage-dependent manner, the conductance of membranes containing many channels formed by the PAn5 fragment o f anthrax toxin. In this paper we analyze this phenomenon at the single-channel level for tetrabutylammonium ion (Bu4N+). We find that Bu4N + induces a flickery block of the PA65 channel when present on eith...
