In this paper, we propose an experimental study for hybrid voting algorithm based on observer and robust control design for two mechanical sensor faults. The proposed strategy is applied for the induction motor speed drive of electrical vehicle powertrain. To adopt the best performance method for electrical vehicle application, we illustrate the effectiveness of the hybrid voting algorithm approach with the New European Driving Cycle (NEDC) speed profile. The experimental results demonstrate the effectiveness of the proposed Input/Output FTC architecture.

The Internet of Things (IoT) is an emerging computing concept, which fuses the digital world and the physical world by bringing together different concepts and technical components. In this paper, we present a new mobile workflow management system (MWfMS) that handles the service of computer and peripherals repair and maintenance. It allows for (i) submission of service requests, (ii) provision of real-time notifications on work progress, (iii) automatic assignment and distribution of workload among the technical-support staff, and (iv) provision of quick solutions to known problems taken from database, without having to register for a new service request. The proposed MWfMS comprises a physical layer linked by the Internet to a remote workflow management hub (WfMH). The real objects (i.e. system stakeholders and their mobile devices represent the physical layer. The WfMH that hosts the main business logic and data storage is responsible for virtualization of physical objects, and creation and delivery of various management services to the end users. A fully functional prototype of the proposed system is designed and developed and its end-to-end functionality is tested successfully.

Most of the hospitals, medical centers and outpatient clinics in Jordan have made major investments in transferring their manual health records to electronic health records (EHRs). However, heterogeneity and lack of appropriated middleware made these EHRs inaccessible on the national level despite the availability of advanced telecom infrastructure in the country. This paper presents a new central middleware architecture that enables seamless and secure exchange of data and services between the local EHRs and a remote national EHR database system. The proposed middleware tackles a standing interoperability problem between these distributed healthcare entities and thus enables the caregivers to access EHRs of their patients on the national level without restrictions of time or geographical location. This is achieved by developing a structured form of interoperability between distributed clients and servers and the central EHR database server that simplifies the integration process and shifts the complexity towards the central middleware system. The developed pilot middleware prototype has demonstrated seamless and secure exchange of data and services.

On-line handwriting analysis and synthesis have become a topic of great interest over the last years and identified as a still-open research issue in various fields, including Artificial Intelligence. This paper proposes an artificial simulator for the analysis and synthesis of cursive handwriting signals based on the beta-elliptic model. The beta equation used for this model describes the velocity profile in the kinematics domain which, in turn, is represented by an elliptic arc that characterizes the handwriting trajectory in the static domain. The beta-elliptic model is used to develop a simulator model that produces both movement kinematic profiles, such as velocity and acceleration, and position patterns of the approximated handwriting trajectory. The model consists of three interconnected sub-systems constructed via the Matlab-Simulink tool. In order to test the performance of our proposed enhanced model and simplify the control and simulation of handwriting features, including movement amplitude, duration, and size, experimental cases were performed under ideal and noisy conditions. The results demonstrated the efficiency of the enhanced model in producing handwriting signals and its robustness in handling the variation of handwriting features.

This paper investigates the use of fractional Fourier transform (FrFT)-based Orthogonal Frequency Division Multiplexing for Synthetic Aperture Radar (SAR) imaging for single point target and extended target. The geometry of synthetic aperture radar using FrFT-based OFDM is presented with the developing algorithm to process the raw data to reconstruct the image of the target in the range and in the Azimuth direction. In the simulation results, single point target is assumed to be at the center of swath width to show the performance of this approach as well as the point spread function in the range and Azimuth direction. Extended target with the shape of tank is used to show the capability of this method in resolving extended target images.

The development of multimedia embedded applications continues to increase. As an example, image recognition applications are not only developed for the PCs but also for the embedded systems such as the face recognition, the texture detection and the edge detection. In this paper, we will present a hardware architecture based on an adaptation approach. To validate this architecture, an edge detection approach is chosen. To illustrate the proposed approach, vehicle registration plate recognition is proposed. The latter application was tested in a first time by a software implementation. n a second time, we use the co design technique based on a mixed Hardware Software architecture. The used platform for the implementation is the Xilinx ML 507 FPGA platform.

In this contribution, we present a multiple-input multiple-output (MIMO) transceiver scheme for high-speed chip-to-chip communication over low-cost electrical interconnects. Linear MIMO pre-equalization at the transmitter is combined with decision feedback equalization (DFE) at the receiver to counteract the adverse effect of inter symbol interference (ISI) and crosstalk (XT). Considering an energy constraint at the transmit side, we derive elegant closed-form expressions for the equalization filters under a minimum mean square error (MMSE) criterion. Numerical analysis shows that the combination of linear MIMO pre-equalization and MIMO DFE allows to significantly improve the reliability of future high-speed off-chip communication.

This paper presents a method for the design of decentralized state observer-based control for a class of systems which are modeled as nonlinear subsystems linked by nonlinear time varying interconnections. The non linearity of each subsystem satisfies the Lipschitz condition and the only information about the nonlinear interconnection is that satisfies a quadratic constraint. The key to our work is, in one hand, the reformulation of the Lipschitz condition and the quadratic constraint using the differential mean value to simplify the design of estimation and control matrices gains, and in another hand the use of the Lyapunov's direct method stability analysis. Sufficient conditions that ensure the existence of observer based feedback controller are established in terms of linear matrix inequalities. A numerical example is given to mark the effectiveness of the control design.

The sliding mode control (SMC) is a variable structure, widely spread control strategy thanks to its efficient features such as robustness, easy implementation and reliability regarding disturbances and nonlinear uncertainties. Firstly, SMC has been implemented on a robot manipulator with three degrees of freedom used for a surveillance camera system. Then, and in order to improve the robustness of the proposed approach, an additive measurement's noise has been introduced. Simulation results show the efficiency of the Sliding Mode Controller applied to a robot manipulator system in a motion control task, which is used to ensure the displacement of a surveillance camera.
