The paper presents a neuro-fuzzy model of the inverse kinematics of 4 DOF robotic arm employing the relevance vector learning algorithm. Although the direct kinematics of the robotic arm can be modeled with ease by the same approach, the paper focuses on the much more interesting kinematic task, since its solution presents a basis for robot control design. The presented model is of a Takagi-Sugeno type, but its parameters and number of fuzzy rules are automatically generated and optimized through the adopted learning algorithm based on M. E. Tipping's relevance vector machine. The presented model illustrates the effectiveness of the adopted neuro-fuzzy modeling approach.

Support Vector Regression (SVR) is an attractive approach for data modeling. The SVR is based on mapping nonlinear input to a linear in the feature space. Instead of minimizing the observed training error, SVR minimizes the generalization error bound using structural risk minimization in combine with a kernel trick control. The model selection plays an important role to the performance of SVR. Therefore, in SVR problems, we attempt to generalize the model by maximizing the margin. Based on experimental results, intelligent model selection is crucial to avoid over fitting and overestimating of generalization capability in such a multidimensional dataset. SVR techniques for choosing the kernel function and additional capacity control is still ongoing research. In this paper, we develop Genetic Folding (GF) for kernel selection of SVR. This methodology was motivated and proofed by our previous published works [4] in classification models. At the end, we have shown comparative results in comparing to predefined kernel models.

Now-a-days the social Networking sites are gaining most popularity due to the ideal and efficient way of communication between two parties. However, during communication between two parties it may possible that some abusive words are to be used may be intentionally or unintentionally that is referred as Flaming during communication. This paper mainly focuses on the Flame detector model, which will capture the status of the user with the help of the web services from social networking sites and store it in to the local computer. The Flame Detector Model will find the flaming words from the status & provide the flaming words as inputs to the Flame intensity, which is one section of whole Flame Detection Model, will show the flame intensity level based on the inputs. The flame intensity also generates graph representing the intensity.

Cooperative synchronization of a multi-hop wireless communication networks is investigated in this paper. First, a basic and typical dual-hop network which consists of coupled chaotic systems is discussed, and synchronization has been achieved via the nonlinear integral control method. On the basis of this model, the study of the cooperative synchronization is extended to the multi-hop networks. Two network topologies, namely the MESH network structure and the MOORE neighborhood structure, are considered. Also, the nonlinear feedback integral method is used as the control law. Simulation results demonstrate the effectiveness of modeling the communication networks and the perfect synchronization of the multi-hop network consisting of chaotic nodes.

This paper presents a novel design of a compact multi-valued inverter circuit using Carbon Nanotube Field effect Transistor (CNTFET). All simulations are done by using HSPICE model of CNTFET. The novelty of this paper is by using only one circuit all multi-valued output can be achieved than using three different CNTFET circuits or complex band-gap reference circuits to produce each reference voltage for precise output in case of CMOS implementation which are previously done. Also the same design implementation using MOSFETs with different threshold mask would increase higher process cost. It is widely considered that CNTFET possesses high fabrication feasibility and superior device performance than MOSFET. The extensive simulated results and performance bench-marking of the proposed design also show a significant reduction in power delay product (PDP) which aids over 50% faster speed than typical multi-valued inverter. Hence with this uniquely new design it is possible to accomplish simplicity, energy efficiency and of course reducing the chip area in modern ultra low power VLSI circuits.

Compressed air systems account for much of the total energy use by European industries. Air compressors alone account for over 10% of UK industrial energy use (>;15,000 GWh). Many of these systems are not optimized to save energy and money, and to have more reliable compressed air power. We present here an integrated optimization solution for the design of such systems. The input to the design procedure is an audit of the air usage pattern and the user defined requirements of the compressed air system. A multi-objective optimiser proposes a design solution. It generates candidate system configurations with alternative equipment, minimises, on-the-fly, the energy use of these using a SIMULINK simulator, computes predicted lifecycle cost, and selects the configuration which meets the specifications and gives the lowest 10 year life-cycle cost.

Interconnection Network is a significant component in parallel processing system (PPS). Multistage interconnection network (MIN) plays a vital role in order to design efficient PPS. In the present research scenario, obtaining a cost effective and fault tolerant MIN is a critical challenge. This paper introduces a new fault tolerant irregular MIN named as Advance Irregular Augmented Shuffle Exchange Network (AIASEN). The proposed MIN is the advance form of irregular augmented shuffle exchange network (IASEN). It has been observed that AIASEN provides full access capability in presence of multiple faults in the network. It shows better tolerance fault at minimum cost as compare to the IASEN.

A benchmark medical study is realized for a Primary Biliary Cirrhosis (PBC) dataset by using two different versions of a Bayesian Neural Network (BNN) entitled Partial Logistic Artificial Neural Network for Competing Risks with Automatic Relevance Determination (PLANN-CR-ARD). The two BNN versions are based on two different compensation mechanisms which are designed to preserve the numerical stability of the PLANN-CR-ARD model and to calculate the marginalized network results. The predictions of the PLANN-CR-ARD models are comparable to the non-parametric estimates obtained through the survival analysis of the PBC dataset. The input variables from the PBC dataset which can have a strong influence on the outcome of the disease are determined. The PLANN-CR-ARD models can be used to investigate the non-linear inter-dependencies between the predicted outputs and the input data which consist of the characteristics of the PBC patients.

In recent times Massive Multiplayer Online Game has appeared as a computer game that enables hundreds of players from all parts of the world to interact in a game world (common platform) at the same time instance. Current architecture used for MMOGs based on the classic tightly coupled distributed system. While, MMOGs are getting more interactive same time number of interacting users is increasing, classic implementation architecture may raise scalability and interdependence issues. This requires a loosely coupled service oriented architecture to support evolution in MMOG application. Data flow architecture, Event driven architecture and client server architecture are basic date orchestration approaches used by any service oriented architecture. Real time service is hottest issue for service oriented architecture. The basic requirement of any real time service oriented architecture is to ensure the quality of service. In this paper we have proposed a service oriented architecture for massive multiplayer online game and a specific middleware (based on open source DDS) in MMOG's for fulfilling real time constraints.
