We investigate nonlinear behaviors of light known as bifurcation and chaos within a nonlinear silicon microring resonator (SMRR). The research is used to controlling SMRR's behaviors such as chaos applicable in security coding systems. The variable parameters affect the bifurcation to be happened in smaller roundtrip among total round trip of 20000 or input power. Simulated Results show that rising of the nonlinear refractive indices, coupling coefficients and radius of the SMRR leads to descending in input power and round trips wherein the bifurcation occurs. As result, bifurcation or chaos behaviors are seen at lower input power of 44 W, where the nonlinear refractive index is n 2 = 3.2×10 -20 m 2 /W. Smallest round trips of 4770 and 5720 can be seen for the R = 40 μm and k = 0.1 respectively. The controlled chaotic signals from the SMRR are passing through a polarizer beam splitter to generate quantum binary codes which are used in wireless network communication.

Carrying out business processes by means of software services helps to close the business-systems gap, by introducing an intermediate layer between business process definition and software systems, thus permitting not only better independence, but also more traceability between them. Despite the fact that technologies have matured to support this new reality, there is a lack of methodologies and notations, although some have been proposed to guide service development with different visions of service design and implementation. Service modeling is the basis for, among other things, the automation of several development steps by means of the model-driven development paradigm. The SoaML standard is a major step towards service modeling in UML. In this paper we extend our Business Process Service Oriented Methodology (BPSOM) for service development from business processes by integrating two main aspects: service modeling using SoaML and QVT transformations to obtain SoaML service models from BPMN BP models. © 2011 Springer-Verlag.

Vehicular Ad-hoc Networks are a very interesting self-organizing communication system that can make the traffic on our roads much safer. A lot of aspects of the behavior of these systems are studied using network simulation frameworks. While the upper communication layers of Vehicular Ad-hoc Networks are mainly simulated according to their specifications, in this paper we will highlight weak points in these simulations. They occur due the fact that the layers below the link layer are considered very rarely and are also almost neglected by the commonly used network simulation frameworks. This can potentially lead to inaccurate simulation results which can be fatal when studying safety relevant applications or application with real-time constraints. In this work in progress paper we are going to propose an approach to get this under control.

The aim of this work is to propose a multifractal analysis method for Multifractal Detrended Fluctuation analysis (MF-DFA) of Blood Oxygen Level Dependent (BOLD) functional Magnetic Resonance Imaging (fMRI). The fMRI signals exhibit a 1/f power spectrum, hence their structure has self-similarity and long memory, being usually successfully analyzed by different fractal analysis methods without a previous knowledge of haemodynamic models. Therefore, to validate activation detection using the MF-DFA method, a comparison study between images obtained using General Linear Model (GLM) and Independent Component Analysis (ICA) was conducted and evaluated by discrimination power, applying Receiver Operating Characteristic (ROC) analysis to the results.

In this paper a novel decentralized approach for task sequencing within a multiple missions control framework is presented. The main contribution of this work concerns the decentralization of a control framework for multiple mission execution in order to enhance the robustness of the system, and the application of the latter to a heterogeneous robotic network. The proposed approach is based on the Matrixbased Discrete Event Framework (MDEF). This formalism is adapted to networks of heterogeneous robots, i.e., robots with different capabilities, and to the decentralized control of mission execution using a consensus-based approach which guarantees the agreement among robots on executed actions and their consequences.

One of the main recent achievements in engineering is description of complex products and their physical environment in a single object model. This model has capabilities to serve engineering from the first specification of a product to recycling. New research programs were needed in order to establish a new style of engineering where engineers communicate model creation and application procedures. The authors joined to these efforts and developed new modeling methods for the above purpose. In this paper they introduce some of these methods considering needs by the complex and knowledge intensive engineering for robot systems. Paper starts with an outline of application of virtual spaces in robot system modeling. Following this, a content based contextual object definition is explained considering robotic application. Next, application of human control by contextual spaces for adaptive definition of engineering objects and the related control of product definition are shown. Finally, object space for robot system is outlined as application related issue of the proposed modeling. © 2010 IEEE.

This paper presents an efficient method for the design of M-channel oversampled warped cosine-modulated filter banks. The method consists in filter prototype design for synthesis filter bank using optimization procedure, which minimizes filter bank overall distortion transfer function. Optimization takes into account channel subsampling factors as well. Copyright © 2010 by institute of Electronics, Silesian University of Technology.
