Time variability of reservoir parameters in water flooding has an effect on oilfield development rules. Meanwhile, time variability of different reservoir macro-parameters has certain synergetic relationship with each other. Based on microscopic network simulation and reservoir numerical simulation, a new simulation method is presented, which can describe the influence of reservoir parameters' ...

A new synergetic model based on a pulse neural network and the Perona-Malik anisotropic diffusion algorithm is introduced. The proposed model was developed because of the failure of conventional edge detectors to perform the extraction of geometric structures from low contrast edges and noisy assumed uniform regions. The synergetic model is a variation of the Perona-Malik algorithm that incorpo...

Cooperators forgo their own interests to benefit others. This reduces their fitness and thus cooperators are not likely to spread based on natural selection. Nonetheless, cooperation is widespread on every level of biological organization ranging from bacterial communities to human society. Mathematical models can help to explain under which circumstances cooperation evolves. Evolutionary game ...

In the field of parallel programming we notice a considerable lack of efficient on-line tools for debugging, performance analysis etc. This is due to the fact that the construction of those tools must be based on a complicated software infrastructure. In the case of such software being available tools from different vendors are almost always incompatible as they use proprietary implementations ...

This paper presents a novel optical-electronic shape recognition system based on synergetic associative memory. Our shape recognition system is composed of two parts: the first one is feature extraction system (FES); the second is synergetic pattern recognition system (SPRS). Hough transform is proposed for feature extraction of unrecognized object, with the effects of reducing dimensions and f...

Exploiting new, low-cost and efficient electrocatalysts for hydrogen evolution reaction (HER) is important to resolve the energy crisis and environment pollution. In this work, graphene decorated with Ni nanoparticles (NPs) were synthesized via one-pot reduction using graphene oxide (GO, the obtained composite was denoted as GN) as a precursor. The as-prepared composite GN exhibits much better ...

a fundamental study of scale formation of calcium carbonate (caco3) for producing oil wells hasbeen carried out. this article presents the study of the prediction of salt deposition in two differentsynthetic formation waters and investigates the effects of temperature and pressure on calciumcarbonate precipitation. the dependence of the induction period of the precipitation of calciumcarbonate ...

teachers’ verbal behavior is a key contributor to provision of appropriate indirect intervention in language learning contexts; however, it is surprising that professionals in elt, to date, have not proposed a structured oral/verbal framework to deliver intervention and assistance in language learning contexts. to help redress this gap, heron’s six-category intervention analysis was adapted to ...

Aim: The combination of different antimicrobial agents and subsequent synergetic effects may be beneficial in treatment of P. aeruginosa infections. The aim of the present study was to determine antibiotic susceptibility patterns of clinical isolates of P. aeruginosa and the effect of different antibiotic combinations against the multidrug-resistant (MDR), biofilm-producing bacterium P. aerugin...
