The wormhole move: A new algorithm for polymer simulations
نویسنده
چکیده
A new Monte Carlo move for polymer simulations is presented. The “wormhole” move is build out of reptation steps and allows a polymer to reptate through a hole in space; it is able to completely displace a polymer in time N (with N the polymer length) even at high density. This move can be used in a similar way as configurational bias, in particular it allows grand canonical moves, it is applicable to copolymers and can be extended to branched polymers. The main advantage is speed since it is exponentially faster in N than configurational bias, but is also easier to program.

A Secure Routing Algorithm for Underwater Wireless Sensor Networks
Recently, underwater Wireless Sensor Networks (UWSNs) attracted the interest of many researchers and the past three decades have held the rapid progress of underwater acoustic communication. One of the major problems in UWSNs is how to transfer data from the mobile node to the base stations and choosing the optimized route for data transmission. Secure routing in UWSNs is necessary for packet d...
متن کاملPhase behavior of monomeric mixtures and polymer solutions with soft interaction potentials
We present Gibbs ensemble Monte Carlo simulations of monomer–solvent and polymer–solvent mixtures with soft interaction potentials, that are used in dissipative particle dynamics simulations. From the simulated phase behavior of the monomer–solvent mixtures one can derive an effective Flory–Huggins x-parameter as a function of the particle interaction potential. We show that this x-parameter ag...
متن کاملA Robust Distributed Estimation Algorithm under Alpha-Stable Noise Condition
Robust adaptive estimation of unknown parameter has been an important issue in recent years for reliable operation in the distributed networks. The conventional adaptive estimation algorithms that rely on mean square error (MSE) criterion exhibit good performance in the presence of Gaussian noise, but their performance drastically decreases under impulsive noise. In this paper, we propose a rob...

This paper proposes a distributed wormhole detection algorithm for wireless sensor networks, a potential technology for infrastructures of many applications. Currently, most sensor networks assume they will be deployed in a benign environment; however, when a sensor network is deployed in some hostile environment, attacks (especially those like wormhole attacks that don’t need to capture the ke...
متن کاملSimulation Study of Salinity Effect on Polymer Flooding in Core Scale
In this study, simulation of low salinity polymer flooding in the core scale is investigated using Eclipse-100 simulator. For this purpose, two sets of data are used. The first set of data were adopted from the results of experimental studies conducted at the University of Bergen, performed using Berea sandstone and intermediate oil. The second data set, related to sand pack and heavy oil syste...
