This paper considers a proposed algorithm for computation of the inverse kinematic(IK) model of the human arm. This algorithm introduces a new IK method suitable for reaching tasks performed by autonomous and interactive virtual humans. The basic problem is to pose the character in such a way that arm hand reaches the target ( position and orientation ) in space. The algorithm is composed of two phases. The first phase is the limitation of real task which concerning the human arm movement and the second phase presents the analytical solution for inverse kinematic problem (IKP) by trigonometric relations and algebraic solution according to limitation of joints. This algorithm is simulated by using MATLAB Ver. R2008a, and satisfied results are obtained, that explains the ability of the proposed algorithm to solve the inverse kinematic problem for real human arm.

This paper presents voltage rise due to inter-connection of embedded generators to distribution network on weak feeder. Studies were performed on Malaysia's 11kV network using a simulation tool called PSS ADEPTTM. Various scenarios were investigated such as EG penetration level, location of EG plant, sizing of feeder (distance from MAIN substation), loading of network, Automatic Voltage Control relay set point at MAIN substation, power factor of network and various operating mode of EG. It is concluded that the introduction of EG at the distribution network will cause voltage rise and this leads to customer voltages being out of the allowable range. Through careful design of the connection arrangement, Distribution Network Operator (DNO) can ensure that the new EG connection does not cause problems and at the same time, enhance the performance of the network.

T-wave alternans (TWA) is a marker of cardiac instability and high risk of sudden cardiac death. In this paper we propose a new approach for the TWA detection. For this purpose Lyapunov spectrum was calculated from T-wave time series. To evaluate the detector performance, simulated T-waves based on the real ECG signals were used. Detected and simulated episodes were compared, in terms of sensitivity and positive predictivity. The results show that this method can reliably detect T-wave alternans episodes.

Wireless networks are increasingly being implemented and its acceptance in the society is booming. In this paper, the performance analysis of 802.11 networks was done for different standards like IEEE 802.11a, 802.11b, and 802.11g in different scenarios. The throughput and traffic dropped for such networks in homogeneous and heterogeneous groupings were studied. Also Bluetooth nodes were tested with 802.11b nodes and the network performance was analyzed. Observations on performance were eventually done based on these network simulations that were implemented using existing network models.

In this paper, Training-Based Channel Estimation (TBCE) method is considered in the Rician flat fading Multiple-Input Multiple-Output (MIMO) channels. In this channel model, the performance of the conventional Least Squares (LS) channel estimator is probed first. A new shifted type of Scaled Least Squares (SLS) channel estimator, entitled as SSLS, is then proposed. It is a generalized form of the SLS technique. The optimal choice of training signals using Mean Square Error (MSE) criterion is also achieved. It is observed that the LS estimator cannot exploit the knowledge of channel statistics. However, the SSLS estimator exploits the trace of a specifically defined matrix of the channel covariance and the receiver noise power as well as the knowledge of first-order statistics about the channel. It is shown that in the Rician fading MIMO channel, the new channel estimator has better performance than the popular LS and SLS techniques. Theoretical analysis and simulation results demonstrate that increasing Rice factor is a reason for decreasing MSE of the proposed estimator.

Damping local mode and inter-area oscillations are two critical issues for optimal power flow and stability in a power system. Power system stabilizers (PSSs) are applied to damp these oscillations. Conventional algorithms of PSS design are based on classical control theory and eigen values based calculation and involve numerous mathematical calculations which may not present an accurate solution. In this paper, a particle swarm optimization (PSO) based PSS design is suggested which is based on time domain response of power system and also is robust for the overall credible disturbances in power system. Two-area (four-machine 11-bus) power system is considered as the case study in this paper. PSS parameters are obtained for four PSS connected to four generators. Finally, the effectiveness of the proposed algorithm is evaluated for damping the system oscillations during overall disturbances. The simulation results illustrate this issue.

Web databases are convenient methods of sharing and retrieving data as well as a key component of the information system infrastructure of today's modern research, as they are valuable tools to facilitate research for effective treatment of diseases. In this paper, we present the method employed to deploy an Alzheimer's disease (AD) database by Abdul Rahman et. al. on the Malaysia Research and Education Network (MYREN). The link to MYREN would facilitate resource sharing among MYREN members over a high-speed backbone network.

A malicious node in mobile ad hoc networks (MANETs) can falsify a route advertisement, overwhelming traffic without forwarding it, helps in forwarding corrupted data, and injecting of false or uncompleted information. Mapping immune system security mechanisms to networking security can powerfully contribute in securing MANETs, since both are sharing some similar features because of the distributability environment in each. In a step for providing secured and reliable broadband services, formal specification logic along with a novel Immune-inspired security framework (I2MANETs) have been introduced. The different immune components synchronized to the framework through an agent that has the ability to replicate, monitor, detect, classify, and block/isolate the corrupted packets and/or nodes in a federated domain. The framework functions as the Human Immune System in: first response, second response, adaptability, distributability, survivability and other immune features. The I2MANETs can basically installed in one node in the domain, then automatically spread to the rest of the domain.

Wind is known as a source of power, which changes both magnitude and direction. As a result, the produced power by the generator with a wind turbine fluctuates. Therefore, the objective of this paper is to present a grid connected inverter with unity power factor for wind power applications. The current source of grid connected inverter is implemented by controlled the voltage in phase with current in order to the power flows from variable dc source to power line all time. The system characteristic of the voltage and current of grid-connected inverter as before and after synchronization to power utility are investigated by using MATLAB/SIMULINK simulation and hardware experiment. The experiment results are given, which the inverter output voltage and current are sinusoidal at 50 Hz. of frequency, the both waveform are low harmonic distortion and the current is enforced in phase with the voltage both before and after synchronization all time.
