This paper provides an attempt to solve the problem of restoring Linux processes tree during container live migration by creation a mathematical model describing operations, which are performed with container processes tree while container works. During live migration of the container, the state of each process in the container processes tree is saved and then the tree is restored on another node...
Changing the development environment can have severe impacts on the system behavior such as the execution-time performance. Since it can be costly to migrate a software application, engineers would like to predict the performance parameters of the application under the new environment with as little effort as possible. In this paper, we concentrate on model-driven development and provide a methodology...
Based on two-way wave equation, prestack reverse time migration (RTM) overcomes dip limitation, and can image complicated geological body with high precision. However, since the massy storage, large amount of computation, low frequency noise, the industrialization process of this approach develops slowly. High order finite difference algorithm is used to calculate reverse time migration in the paper...
The Restriction of Hazardous Substances (RoHS) in electronic equipment imposed by legal considerations does not allow the manufacture of electronic equipments with alloys containing lead. As an ecological alternative, it can be used lead free alloys. Electrochemical migration is a reliability problem in printer circuit boards in high humidity environments. In this paper, the electrochemical migration...
This paper presents an investigation into the migration from standard centralized control to modular, distributed control for a fruit packing machine. Along with control that was developed using IEC 61499, a simulation model of the plant was developed in parallel. Both were deployed to hardware to demonstrate seamless testing using a single underlying architecture. A visualization of the simulation...
Estimation the shape and position of the objects is an important subject in ground penetrating radar(GPR). Migration method in domain of seismic techniques is effective to locate and reshape the objects. Kirchoff migration method is based on electromagnetic wave equation. It is an accurate calculation method. Kirchoff migration method has widely adaptabilities with different horizontal and vertical...
It has been proposed a method that the all autonomous mobile robots share a common coordinate system without the communication among them and without recognition of the landmarks or maps. However, the effectiveness of the only directional method is confirmed by analysis and simulations. This paper describes the positional modification method, newly. The effectiveness of is confirmed by the simulations...
Arsenic displays complex nature in groundwater. The study of geochemical properties of arsenic in groundwater enables not only the prediction of arsenic pollution trend in groundwater, but also the prevention and mitigation of arsenic pollution. This article is mainly about using soil column dynamic experiment to simulate the arsenic kinetic behavior when it migrates in groundwater environment. Studies...
Sociodemographic studies on human migration phenomena are mostly based on surveys and censuses, which significantly increases the research costs. This scenario becomes even worse when the study involves migration and social networks, which often lacks on representative data and consensually accepted concepts by demographers and sociologists. In this paper we propose a new multi-evolutionary agent...
Agent-based simulation models provide a way to investigate social phenomena that complement existing social science methods. Recent advances in computing hardware such as the wide availability of multi-core CPUs and increased main memory capacities make it possible to investigate population-scale phenomena using commodity compute resources. This paper describes experiences made in the development...
An alternative to classical fault-tolerant approaches for large-scale clusters is failure avoidance, by which the occurrence of a fault is predicted and a preventive measure is taken. We develop analytical performance models for two types of preventive measures: preventive checkpointing and preventive migration. We also develop an analytical model of the performance of a standard periodic checkpoint...
Continuous queries are the more interesting class of data stream queries. The answer to a continuous query is continuously produced over time unless stopped artificially. During an executed continuous query, the run environment changes continuously, meanwhile some properties of data stream itself change too, such as input rate, selectivity of operators and execute time and so on. In order to adapt...
This paper presents Biogeography Based Optimization (BBO) technique for solving constrained economic dispatch problems in power system, Considering valve point nonlinearities of generators. In this paper, two ELD problems of different characteristics have been used to investigate the effectiveness of the proposed algorithm A comparison of simulation results reveals that the proposed algorithm is better...
Oil production and processing industry result in a large number of petroleum hydrocarbon contaminants into groundwater system, destroy the original ecosystem and harm the human health. In this paper, groundwater system in an oil refinery was selected as the research object. In order to predict migration of petroleum hydrocarbon contaminants in groundwater system in the study area, effects of mechanical...
In this paper, a mathematical model of nickel electrode for single flow zinc-nickel battery is developed based on the previous models. Diffusion and migration in the electrolyte phase as well as proton diffusion and ohmic drop through the solid active material in the porous nickel electrode are all taken into account in this model. The most complicated segments, such as the beginning segment of charge...
This work focuses on modeling of film porosity in thin film deposition using stochastic differential equations. A deposition process is modeled via kinetic Monte Carlo (kMC) simulation on a triangular lattice. The microscopic process events involve atom adsorption and migration and the film growth allows for vacancies and overhangs to develop inside the film. Appropriate definitions of film site occupancy...
The travel time calculation of seismic wave propagation in synthetic earth models is a fundamental technique needed for Kirchhoff seismic modeling and migration. Migration is a process used to image the subsurface. In this paper, using layer-based models, a genetic algorithm (GA) approach is presented to calculate the travel time, and implement GA for Kirchhoff ray tracing modeling and Kirchhoff migration...
