A key issue faced by such efforts is the expandability of the network model. This paper discusses the development of a cellular automata framework for micro-simulation of vehicle traffic flow in road networks and highways, which was implemented on MATLAB. Attention has been paid to the modularity of the proposed model, in order to provide not only expandability, but also parameterization and independency from simulation rules. Our goal is to accomodate the study of traffic critical properties by including several parameters in the model and facilitate the construction of hierarhical modular traffic models and the experimentation with alternative simulation rulesets. The first step of this integrated methodology is to validate the proposed framework, by presenting numerical results and comparisons.","PeriodicalId":91410,"journal":{"name":"Summer Computer Simulation Conference : (SCSC 2014) : 2014 Summer Simulation Multi-Conference : Monterey, California, USA, 6-10 July 2014.

This approach uses Radial Basis Networks, RBN, which have the advantage of not being locked into local minima as do feedforward Neural Networks. The RBNs are simply linear function approximators that use Radial Basis Functions which are powerful techniques for interpolation in multidimensional space. The RBN is used to evaluate the stresses accompanying this mode of operation which may result in the failure of the diodes in the rotating rectifier bridge of the generator brushles field exciter. The modeling approach is applied in a case study of two standalone synchronous generators system for aerospace applications. This study resulted in the prediction of the system performance characteristics including the peak currents and reverse voltages of the rotating diodes. The simulation results were validated by comparison to experimental data.","PeriodicalId":91410,"journal":{"name":"Summer Computer Simulation Conference : (SCSC 2014) : 2014 Summer Simulation Multi-Conference : Monterey, California, USA, 6-10 July 2014.

The primitive operations were selected from the five finalist algorithms of the Advanced Encryption Standard (AES [1]) contest. These algorithms are promising for the selection of the new Encryption Standard, which was to replace the Data Encryption Standard (DES). As Field Programmable Gate Arrays (FPGAs) offer high flexibility and a low cost alternative for implementing these algorithms in Application-Specific Integrated Circuits (ASIC), these primitive operations are implemented in an Altera FPGA to permit user-programmable alternatives for a different encryption/decryption algorithm as opposed to a preselected one by a manufacturer.

Electromigration which occur under high current density is the major concern for the nanoelectronics industry. Using a general purpose computational model, which is capable of simulating coupled electromigration and thermo-mechanical stress evolution, several dual damascene copper interconnect structures have been investigated for electromigration damage. Different diffusion boundary conditions including blocking and non blocking boundary conditions, current crowding effects, interface diffusion effects and material plasticity have been considered. Different damage criteria are used for quantifying material degradation. The computational simulation results match the experimental findings; therefore the model proves to be a useful tool for simulating damage evolution in electronics interconnects.","PeriodicalId":91410,"journal":{"name":"Summer Computer Simulation Conference : (SCSC 2014) : 2014 Summer Simulation Multi-Conference : Monterey, California, USA, 6-10 July 2014.

The latter term refers to a new watermarking algorithm based on embedding mark (signature) in both spatial and multi-resolution domain. For the purpose of increasing the image watermarking robustness against attacks of an image transmission, we encode with a turbo code an image-embedded mark. This new scheme of image watermarking is able to embed 2000 bits in medical images. Results of experiments carried out on a database of 30- 256x256 pixel-sized medical images show that watermarks are robust to Noises, Filter attacks, JPEG Compression and geometric distortion such as Cropping. Results demonstrate that fidelity can be improved by incorporating a codage that is shaped into the embedding process. Other advantages of the two embedding domains are to preserve intellectual features and to secure the mark in the image. \u0000 \u0000The image degradation is measured by Relative Peak Signal to Noise Ratio (RPSNR). Experimental results show that this unit of measurement is the best distortion metric witch is correlated with Human Visual System (HVS); and therefore more suitable for digital watermarking.","PeriodicalId":91410,"journal":{"name":"Summer Computer Simulation Conference : (SCSC 2014) : 2014 Summer Simulation Multi-Conference : Monterey, California, USA, 6-10 July 2014.

Unfortunately the notion has an elusive characterization and one might easily get the impression that it is merely a notion and is not, in fact, an actual artefact. The situation borders on the paradoxical in view of the widely acknowledged importance of the conceptual modelling concept. Our intent in this paper is to address this curious situation by presenting a specific framework for the development of conceptual models for simulation studies of discrete event dynamic systems. \u0000 \u0000The framework is essentially a perspective that is supported by a variety of constructs that enable its application within any given problem context. It accommodates, in a common format, both the structural and the behavioural aspects that are fundamental components of any conceptual model. The framework's environment is flexible and adaptable and provides a collection of constructs both for handling input/output and for dealing with special circumstances such as pre-emption interruption and balking. As might be reasonably expected, its constructs can be readily transformed into simulation models (computer programs) within any of the standard world views. \u0000 \u0000We provide an overview of the essential elements of the framework and illustrate some of its features in several example problems.","PeriodicalId":91410,"journal":{"name":"Summer Computer Simulation Conference : (SCSC 2014) : 2014 Summer Simulation Multi-Conference : Monterey, California, USA, 6-10 July 2014.
