Using Monte Carlo simulations, the cascade transition of a single polyelectrolyte chain having permuted charge distribution is investigated. The polyelectrolyte chain is simulated at various solvent regimes. The effect of the electrostatic interaction strength is studied. The structures are analyzed with respect to the scaling laws. The effect of permuted charge distribution is investigated in comparison to the other charge distribution in the literature.

This paper demonstrates model-based dynamic optimization through the coupling of two open source tools: OpenModelica, which is a Modelica-based modeling and simulation platform, and CasADi, a framework for numerical optimization. The coupling uses a standardized XML format for exchange of differential-algebraic equations (DAE) models. OpenModelica supports export of models written in Modelica and the optimization language extension using this XML format, while CasADi supports import of models represented in this format. This allows users to define optimal control problems (OCP) using Modelica and optimization language specification, and solve the underlying model formulation using a range of optimization methods, including direct collocation and direct multiple shooting. The proposed solution has been tested on several industrially relevant optimal control problems, including a diesel-electric power train.

Wireless sensor networks for monitoring and steering industrial systems have emerged as an important new application area for wireless embedded technology in safety-related systems. Therefore several hardware platforms can be targeted. Due to their flexibility and reconfigurability along with high performance and power efficiency, modern Field Programmable Gate Arrays (FPGAs) are an excellent platform to realize such intelligent sensor networks. On one hand, FPGAs can integrate embedded processors and on-chip memory into a single die and can be easily configured to interface with a wide variety of popular communications protocols like SPI, UART and I2C, which are used for sensor communication. On the other hand, the reconfigurability of FPGAs supports the design of self-organizing computing systems, which are increasingly used in sensor applications. In this paper an FPGA-based wireless smart sensor network that integrates acceleration sensors for increasing safety aspects in cognitive systems used for industrial communication is presented.

An L(0,1)-labelling of a graph G is an assignment of nonnegative integers to the vertices of G such that the difference between the labels assigned to any two adjacent vertices is at least zero and the difference between the labels assigned to any two vertices which are at distance two is at least one. The span of an L(0,1)-labelling is the maximum label number assigned to any vertex of G. The L(0,1)-labelling number of a graph G, denoted by λ0.1(G) is the least integer k such that G has an L(0,1)-labelling of span k. This labelling has an application to a computer code assignment problem. The task is to assign integer control codes to a network of computer stations with distance restrictions. A cactus graph is a connected graph in which every block is either an edge or a cycle. In this paper, we label the vertices of a cactus graph by L(0,1)-labelling and have shown that, △-1≤λ0.1(G)≤△ for a cactus graph, where △ is the degree of the graph G.
