A Blocking Technique for EmulatingVery Large
نویسندگان
چکیده
A new Monte Carlo method for computing thermodynamical properties of very large polyelectrolytes is presented. It is based on a renormalization group relating the original polymer to a smaller system, where in addition to the naively rescaled forces, a corrective nearest-neighbor interaction originating from the short distance Coulomb cutoo is introduced. The method is derived for low T but is in the unscreened case valid for all T. Large polymers with N monomers are emulated by Monte Carlo calculations on smaller systems, K = N=Q. The computational gain of the method is Q 3. It is explored with emphasis on room temperature. Results for N =10000 are presented.

Deblocking Joint Photographic Experts Group Compressed Images via Self-learning Sparse Representation
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 ...
متن کاملA three-stage assembly flow shop scheduling problem with blocking and sequence-dependent set up times
This paper considers a three-stage assembly flowshop scheduling problem with sequence-dependent setup < /div> times at the first stage and blocking times between each stage in such a way that the weighted mean completion time and makespan are minimized. Obtaining an optimal solution for this type of complex, large-sized problem in reasonable computational time using traditiona...
متن کاملImproving Petrophysical Interpretation of Conventional Log by Determination of Real Bed Boundaries
Proper determination of bed boundaries in layered reservoirs is vital for accurate petrophysical interpretation of conventional logs. In the wellbore, logs continuously measure physical properties of reservoir while the properties change stepwise. This continuous representation of logs may lead to ignorance of some high potential reservoir zones. The main reasons for continuous nature of l...

Escherichia coli O157:H7 is found in cattle farms and can live in the intestine of healthy cattle. Mostcases of human illnesses including nonbloody diarrhea, hemorrhagic colitis and hemolytic uremic syndromecan be traced, either directly or indirectly, to cattle. One strategy for reducing the risk of EnterohemorrhagicEscherichia coli (EHEC) infections in human is to reduce the prevalence of inf...

Zinc oxide nanorod arrays (ZnO NRs) were grown on the ZnO seed layers via an aqueous solution using hydrothermal method and their photovoltaic properties were investigated. It was found that the growth period of 20 minutes is the optimum condition for ZnO nanorods growth, the cell containing these nanorods was considered as a reference cell. In order to further increase the cell performance, Zn...
