Microfluidic biochips are replacing the conventional biochemical analyzers and are able to integrate the necessary functions for biochemical analysis on-chip. In this paper we are interested in flow-based biochips, in which the fluidic flow is manipulated using integrated microvalves. By combining several microvalves, more complex units, such as micropumps, switches, mixers, and multiplexers, can...
The enterprise information networks (EIN) are forced to continuously update their service architectures to provide reliable network services. Employing distributed service architecture eases the addition of new applications/services to the existing EIN. However, the newly added applications/services may modify the existing EIN architecture (EINA) thereby necessitate the management scheme to be adaptable...
Collaborative supply chains have become an important element for recent years for many companies to improve their supply chain efficiency. This paper reviews the literature on operation research tools and methods for collaboration in supply chain. First, optimization methods for the collaborative supply chain are presented for both vertical and horizontal collaboration. In horizontal collaboration,...
Globalization has caught up with both developed and emerging financial markets. Significant technological advancements have been made to keep with the expansion of financial markets. Trading mechanisms and platforms have been upgraded with the use of technology, but the inherent risks and its impact on the markets are still not completely understood. This paper emphasizes on the increasing use of...
Diffusion of innovation is a research topic which has been subject to several works in the last years. The diffusion of innovation theory aims to explain how new ideas and practices are disseminated between the members of a social system. A significant part of the existing models are based on the use of parameters which determine the process of innovation adoption, and rely on simple mathematical...
Because of global warming and shortage of fossil fuels, much attention has been paid to plug-in electric vehicles (PEVs) worldwide in recent years. With possibly millions of PEVs on road in the future, it is essential for power network operators, especially distribution network operators, to implement coordinated PEV charging. In this paper, an optimal charging method is proposed for PEVs to maximize...
The characteristics of mobile ad hoc network result in necessity of using the simulation for verification of newly proposed concepts in mobile ad hoc networks. Traditional network simulators are oriented towards low level simulation, which leads to various difficulties when these simulators are used for simulation of high level aspects of mobile ad hoc networks. This paper proposes the use of multi-agent...
The stretching, that is, the distance between the centre of mass of the ssDNA and the antibody, has been studied using the potential of mean force calculations based on molecular dynamics and the explicit water model. Our simulations indicate that the 6 residues Gln43, Gly44, Arg98, Tyr100, Val136 and Thr137, pair interactions of antibody-ssDNA, and the 5 interprotein molecular hydrogen bonds might...
This paper discusses the mathematical model depicting how Bursaphelenchus xylophilus infected pine trees. Firstly, according to the spread mechanism of communicable disease, we established a differential equation model with two species, i.e. pine trees and Monochamus alternatus Hop the--host of Bursaphelenchus xylophilus. Secondly, we studied the stability of system equilibrium under disease-free...
Chemical synaptic transmisssion involves the release of a neurotransmitter that diffuses in the extracellular space and interacts with specific receptors located on the postsynaptic membrane. Computer simulation approaches provide fundamental tools for exploring various aspects of the synaptic transmission under different conditions. In particular, Monte Carlo methods can track the stochastic movements...
In the context of an EU project we discuss design decisions regarding virtual experiments contrasting discovery learning and experiential learning approaches.
Wound healing is one of the promising applications of atmospheric pressure gas plasmas in medicine. Recent clinical studies show a significant reduction of bacterial load in treated wounds without any side-effects. [1] Plasma-generated reactive oxygen and nitrogen species (RONS) are thought to be directly or indirectly responsible for the bacterial elimination. We have been developing a multiphysics...
The Monte-Carlo method (stochastic simulation) is the one of the major tools in statistical physics, complex systems science and many other fields and is considered to be the promising computational scheme to run on nearest future exaflop supercomputers with many thousands and even millions of computational cores. We suggest a technique of the distributed stochastic simulation suitable for running...
Nowadays, even though countries take measures to control the population, it is reported that the total number of global population has reached 7billion. In 21st century, the human society is still faced with the problems about the unprecedented consumption of material wealth and the unprecedented increase in population [1]. So the researchers should study the dynamic changes of resources and population...
Following a constant rise in the complexity and scale of peer-to-peer networks, researchers have looked at biological phenomena in order to develop self-organized, adaptive, and robust management systems. Our focus is on distributed swarm intelligence mechanisms that mimic the behavior of social insects to solve problems such as overlay management, routing, task allocation, and resource discovery...
This paper has been carried out to develop a more efficient fuzzy control system with lower costs. This strategy was applied to a biological wastewater treatment process in order to control the dissolved oxygen and the substrate concentrations. Simulation results and comparisons between different cases are given to demonstrate that this model-based control proves the robustness of the fuzzy control.
Three dimensional network-on-chip (3D NoC) is motivated to achieve better performance, functionality, and packaging density compared to 2D NoC. To facilitate performance evaluation for the design stage, an accurate and flexible environment for simulating the 3D NoC performance is necessary. In this paper, we present a complete high-level simulation platform for 3D NoC called Meshim, based on SystemC,...
This paper presents a hierarchical optimization method for determining optimal operation of a distributed energy system which consists of a distribution network and customers with dispersed generation and storage systems. The optimal operation problem of a distributed energy system is divided into two subproblems; optimal operation of a dispersed energy system for a customer and optimal operation...
This study primarily focuses on the simulation of an astronaut moving the orbital replaceable units (ORUs) into the worksites in spacecraft payloads or removing them from these worksites. The upper limb model is established, which includes three segments of upper arm, forearm, and hand, as well as three revolute joints of shoulder, elbow, and wrist. Joint kinematical parameters during one period were...
A framework was presented, which could rapidly establish the basic packaging scheme of cab and corresponding design tools by simulating the main driving postures.
