The traffic in the high-speed wireless multimedia network will be a mixture of voice, video and data messages having a large variety of characteristic and inherent requirement. The present work is a medium access control protocol for time division-code division multiple access system to distribute the available bandwidth among the mixture of different traffic classes depending upon their quality of service requirement. The proposed scheme is the combination of packet scheduling algorithm and packet allocation algorithm. The packet scheduling is based on the packet loss probability and total traffic waiting for transmission in the system. It maximizes the fairness of the system. It also maintains the packet loss probability of all the users in the environment within a limit. The packet scheduling algorithm varies the receive power threshold per packet slot dynamically in case the system packet loss probability and/or system average delay crosses a threshold. The packet allocation is based on the number of packet slot per frame. The performance of the scheme is evaluated in a cellular environment consisting of large number of cells with active users having different multimedia applications. The proposed scheme outperforms existing schemes in terms of delay, throughput and packet loss probability.

We present a solution to the Secure Multi-party Computation (SMC) problem in the form of a protocol that ensures zero-hacking. The solution comprises of a protocol with several trusted third parties (TTPs) where there is a possibility of threat to the security. Our protocol unanimously selects one TTP among all TTPs in the SMC architecture that owns the responsibility of all the computation in the system. This TTP is called the master TTP and it is different at different times. The procedure of selecting master TTP could be non-deterministic but it is made deterministic by randomization technique. This ensures that no single TTP controls the entire system all the times. At the same time, this also ensures that no TTP knows where the computation is taking place. This approach is having merit over the other one where only one TTP is given the responsibility to hold entire data of the system. Hence, the chances of corruption can be reduce to negligible when we randomize the selection of one TTP instead of having unknown TTP. Our algorithm works on the concepts of multiple TTP to provide zero-hacking for the entire system owing to the situation that it becomes almost impossible for any party to break the security. Formally it is achieved by imposing high computational complexity on the parties.

Partial discharge (PD) is one of the main causes for eventual equipment failure and it occurs where the electric field exceeds the local dielectric strength of the insulation. The PD signal captured at UHF has many advantages. The finite difference time domain (FDTD) technique, which is a widely used electromagnetic computational method, has been used to model propagation PD discharges generated in the form of a Gaussian pulse. The wave propagation in free space, oil and with a cylindrical metallic obstruction representing core/winding, in the two dimensions is realized and presented in this work. The perfectly matched layer (PML) which is a flexible and efficient absorbing boundary condition (ABC) has been incorporated in the simulations. Further, for localization time difference of arrival (TDOA) approach has been used.

This paper presents the design of a robust course controller for a cargo ship interacting with an uncertain environment using particle swarm optimization (PSO) enabled automated quantitative feedback theory. The plant model considers here is Nomotopsilas second order model, with structure parametric variation. In the present paper we have taken Nomotopsilas second order model as it is valid for high frequencies also, while first order model is restricted to low frequencies. In the present paper, the automated PSO enabled QFT design method is used to synthesize a robust course controller that can undertake the exact amount of plant uncertainty and can ensure a proper trade off between robust stability specifications and tracking performance over the entire range of frequencies. The present work is the continuation of the work done by the first author where controller is synthesized manually with the consideration of same process model. But in this article the PSO technique has been employed to tune the controller automatically that can greatly reduces the computational effort compared to manual graphical techniques. It has also been demonstrated that this methodology not only automates loop-shaping but also improves design quality and, most usefully, improves the quality with a reduced order controller.

This paper introduces a novel variant of PSO called accelerated exploration particle swarm optimizer (AEPSO). The AEPSO algorithm select the particles that are far away from the global solution and accelerates them towards global optima with an exploration power to avoid the premature convergence. The performance comparisons such as search efficiency, quality of solution and algorithmic complexity of the proposed algorithm are provided against different high performance PSOs. The comparison is carried out on the set of 30 and 50 dimensional complex multimodal benchmark functions with and without coordinate rotation. Simulation results indicate that the proposed algorithm gives robust results with good quality solution and faster convergence.

In this paper, we explore memory usage and speed of execution when developing fuzzy applications on a microcontroller. To develop a fuzzy system, various parameters need to be select. Different parameters result in different degrees of accuracy and give different memory cost and execution time. In the experiments, we consider two typical controllers: fuzzy fan control and fuzzy pendulum. We target at PIC18F8722 microcontroller. We implement the example various fuzzy APIs in C for the microcontroller for testing the characteristics of typical fuzzy programs. We explore the tradeoff between the memory cost, and speed. The results show that using table lookup for fuzzy set approach is faster than the calculation. Max-min inference is not always faster than max-product operation. The code size for the example fuzzy program is around 20-30K. The number of instructions increases when we use complex fuzzy inference operation and defuzzification. The data size is increased linearly when the size of fuzzy sets grows.

Efficient methods for detecting electricity fraud has been an active research area in recent years. This paper presents a hybrid approach towards non-technical loss (NTL) analysis for electric utilities using genetic algorithm (GA) and support vector machine (SVM). The main motivation of this study is to assist Tenaga Nasional Berhad (TNB) in Malaysia to reduce its NTLs in the distribution sector. This hybrid GA-SVM model preselects suspected customers to be inspected onsite for fraud based on abnormal consumption behavior. The proposed approach uses customer load profile information to expose abnormal behavior that is known to be highly correlated with NTL activities. GA provides an increased convergence and globally optimized SVM hyper-parameters using a combination of random and prepopulated genomes. The result of the fraud detection model yields classified classes that are used to shortlist potential fraud suspects for onsite inspection. Simulation results prove the proposed method is more effective compared to the current actions taken by TNB in order to reduce NTL activities.

In a deregulated system designed to support open access, decision making has to be transparent and it requires participation of many players whose behavior is governed by diverse interests from profitable trade all the way to security in system operation. In particular, we foresee that decision support tools should be so deployed that they can be accessed anywhere and at any time. This led us to work on introducing Software-as-a-Service model for power system computation - using the internet to provide access anywhere and at any time. We consider different challenges in terms of usability, scalability and security when it comes to delivering required functionality over the web using Software-as-a-Service model. The proposed software architecture called Web Delivery of Network Applications (webDNA), addresses various issues involved in delivering these applications over the web.

This paper presents the implementation aspects of a VI-based multi-axis motion control system for automated test and measurement applications. The system has been implemented using virtual instrumentation technique and PXI architecture which enhances the productivity and reduce the cost through easy-to-integrate application software and PXI modular hardware. The application software of the system has been developed using LabVIEW-based graphical development environment which enables the user to configure the system for single axis or multi-axis operation. Using the front panel of the application software, multi-axis operation can be configured as free-axis or master-slave axes pairs with safety limits. The PXI architecture used for the system is versatile and meets the specific needs of test and measurement applications by adding an integrated trigger bus and reference clock for multi-board synchronization The system presented in this work is being used at National Wind Tunnel Facility (NWTF), IIT Kanpur to develop various motion control model support systems and test rigs. Few of them include model attitude control beta mechanism, single axis/dual axes turntable motion control systems, multi-axis robotic arm and ram-air parachute attitude control test rigs. The motion control function of these systems is integrated and synchronized with the data acquisition and measurement functions for automated wind tunnel testing. However, motion control system presented in this paper has been configured for automated wind tunnel test applications, but can also be easily configured to perform various motion and position control functions for bio-medical, process control, robotics, and CNC machine applications.
