The demand on distribution network reconfiguration abilities is increasing. This paper proposes a Finite State Automaton model of a distribution network that deals with topologically safe reconfiguration. Autonomous operation of distribution networks can be designed, analysed and implemented in day-to-day operation with the aid of these automata: through supervisory control. Two approaches to supervisor design are proposed. One for the normal operating mode and the other for the contingency mode. Simple and comprehensive examples illustrate the approaches. © 2017 IEEE.

As a result of socio-economic growth and paying attention to environmental aspects requirement in order to improve the reliability and achieve higher service, better power quality and increasing energy efficiency are taken more into consideration. Thus, home micro-grids (H-MG) with non-dispatchable Source and interruptible loads can be used as the primary tool to achieve the stated objectives. In order to implement the energy management system (EMS) an algorithm is presented in this paper. EMS which is based on harmony search method for multi-purpose extrapolation of a sample H-MG with renewable energy sources (RES) as well as compound resources of backup power such as micro-turbine and battery for levelling the mismatch of power or for additional power saving in case of necessary. In this paper, the harmony search (HS) for an algorithm to minimize the costs associated with sources, RLD and reduce the price of the electricity (i.e. market clearing price) with respect to the proposed price of production and supply, the price of non-interruptible loads, the optimal production of each of the existing resources in the micro grid is determined. For reliability enhancement the uncertainty is considered in using wind turbines (WT), photovoltaic (PV), load demand and market clearing price in the algorithm. The recommended algorithm system is tested on a H-MG sample. These results show the capability of the HS approach in supplying the load requested. © 2018 IEEE.

The emergence of artificial neural networks (ANNs) caused a great revolution in the knowledge area of pattern-classification and contributed to the fast development of intelligent systems. For an ANN to be effective, its topology parameters must be set up, such as learning rate, number of layers, and number of neurons. Therefore, optimization algorithms can be used to produce more efficient ANNs. In this paper, we propose a genetic algorithm (GA) to better estimate parameters of an ANN applied to the classification of the type, strength, and orientation of different hand movements from electromyography signals. Acquired data signals were first processed with the Wavelet Transform (WT) to extract the most important features. These features were presented to the optimized hybrid intelligent system (HIS) composed of ANNs and the optimization GA. Classification results are promising, presenting accuracy rates above 90% and reliability rate of 98%. These results support the use of HIS in practical applications such as smart prostheses and automatic medical evaluations. © 2018 IEEE.

As the industry of Network of Chips (NoCs) evolves, the reliability and performance of these systems are becoming more critical requirement. The fault tolerance issue is an essential factor that has a direct impact on the reliability of the system. Many techniques were developed to boost the fault tolerance capability of NoCs. This is either implemented on the routing algorithm level or architecture level. This paper analyzes previous work that enhances the fault tolerance by modifying the router architecture. The model of Partial Virtual Sharing (PVS) architecture was modified to improve the fault tolerance capability. We proposed a technique to implement fault tolerance at the input unit of the router architecture. Additional enhancements to implement fault tolerance at the output unit of the router was proposed and implemented too. The reliability of the proposed design was evaluated and compared based on the Mean Time Between Failure (MTBF) metric. The proposed design had shown a remarkable improvement of 263.2% over existing approaches. © 2017 ACM.

The primary manifestations of Parkinson Disease (PD) concern abnormalities of movement associated with the constant deterioration of motor skills. Such motor impairment affects patients' movement accuracy and coordination, disrupting their daily life. Taking into account recent studies stating that computer-based physical therapy games can be used as a PD rehabilitation option, we propose a novel Exergame, the iPrognosis Warming up Game (http://***/), as a user-friendly tool that could both serve as a computer-based physical therapy game, as well as a means of accurately and automatically identifying the severity of PD motor symptoms. To this regard, we propose a novel deep learning methodology for motor impairment stage prediction that relies solely on human body motion data extracted from the recorded game sessions. Experimental results using a dataset of both early and advanced PD patients reveal a good classification performance of the proposed methodology, predicting the motor impairment stage of PD patients and paving the way for additional research in the field.

Despite the development in virtual reality (VR) technology, haptic interaction within large virtual environments (VEs) remains limited. The overall aim of this project is to develop a VR system incorporating haptic interface using a cable-driven parallel robot with accessible motion capture with multiple Kinect sensors for rehabilitation. The immediate objective is to provide preliminary data on the functionality of the novel platform and its components and show its potential for rehabilitation. © 2017 IEEE.

Symmetries are an essential feature of complex networks as they regulate how the graph collective dynamics organizes into clustered states. We here show how to control network symmetries, and how to enforce patterned states of synchronization with nodes clustered in a desired way. Our approach consists of perturbing the original network connectivity, either by adding new edges or by adding/removing links together with modifying their weights. By solving suitable optimization problems, we furthermore guarantee that changes made on the existing topology are minimal. The conditions for the stability of the enforced pattern are derived for the general case, and the performance of the method is illustrated with paradigmatic examples. Our results are relevant to all the practical situations in which coordination of the networked systems into diverse groups may be desirable, such as for teams of robots, unmanned autonomous vehicles, power grids and central pattern generators.

Volume computations are important for the characterization of three-dimensional (3D) objects. In the case of irregularly-shaped objects, volumetric analysis remains challenging due to the missing symmetry in the geometry. 3D scanners provide a solution for digitizing the shape of objects for 3D visualization; however, typical scanners do not provide detailed quantitative information which offers significant advantage in both research and development applications. In this work, tools and operations that utilize digital 3D data captured via a 3D structured-light scanner are investigated to develop algorithms that accurately model and compute the volume of non-uniform objects. Specifically, limpet seashells are utilized to develop the models for volumetric analysis and characterization using MATLAB programming toolboxes after the 3D scans are completed.
