Cardiac arrhythmia detection and classification is of outmost importance for early diagnosis to reduce significantly the rates of morbidity and mortality of patients with heart disease. In particular for patients with silent cardiac symptomatology, the advances in wearable sensing technology offer a promising solution for on-line, real-time detection of intermittent tachyarrhythmia events that otherwise may evolve undetected. In this paper the authors examine some of the key issues that outline the path towards integrating various aspects for ECG signal acquisition and analysis with current trends in wearable sensing technology and present recent results towards on-line real-time arrhythmia classification considering the IoMT (Internet of Medical Things) approach.

Power quality simulation is required to provide an evaluation of the adverse phenomena such as transients, harmonics, and voltage sags in a power system, among others. This paper details a methodology to assess adverse power quality effects. In this methodology, the power system is modeled in the continuous-time by an ordinary differential equations set. The equations set are solved through a numerical integration procedure. The methodology is applied to the modified New Zealand test power system including linear and nonlinear loads. The results are validated through a direct comparison of the state response against the actual response obtained from the time-domain power system simulation performed using the SimPowerSystems toolbox of Simulink®. The obtained results indicate that the methodology accurately estimates power quality harmonic and transient state, respectively.

The frequently excessive vibrations presented in civil structures during seismic events or service conditions may result in users' discomfort, or worst, in structures failure, producing economic and life losses. This work presents the synthesis of a nonlinear optimal control scheme for compensating vibrations in civil structures by means of using magnetorheological dampers (MRD), which are used as semiactive actuator devices for damping the civil structures motion, with the inherent advantage of having a low energy consumption for operating. A three story building is analyzed as a case study, where its movement is investigated by comparing the motion time response with and without control for the MRD (located at the first building floor). Simulation results are presented to validate the effectiveness of the proposed controller for controlling the building damping via a MRD.

Some electricity markets use Locational Marginal Prices (LMPs) to trade energy, but due to transmission lines congestion there may be volatility, existing differences between LMPs from generation points and LMPs in load points. These markets resort to the implementation of Financial Transmission Rights (FTRs) for hedging market participants against that congestion charges. In this paper, a review of FTRs implementation in electricity markets is presented, considering the nature of the problem, mathematical models for FTR auctions, simultaneous feasibility proof, and the challenge of congestion charge revenues are discussed. Also, a brief description of seven FTR markets is presented enlightening important concerns about them.

Operation scheduling is a fundamental problem in mapping an application to electronic devices. In scenarios where these schedules are made on Data Flow Graph (DFG), it is necessary to convert the result to Hardware Description Language (HDL) code. We present a detailed approach for generate VHDL code described in a Data Flow Graph (DFG). We generate VHDL code corresponding to Moore Finite State Machine (FSM), because is similar with the logic of the DFG. We use 20 DFGs from benchmark Mediabench to compute different experiments and we report the occupied area (Slice registers and LUTs) of VHDL codes on a FPGA device. We expose conversions made from DFG scheduling and mapping with As Soon As Possible (ASAP), As Late As Possible (ALAP) and Random scheduling algorithms. All codes are simulated with Xilinx ISE Design Suite to demonstrate its validity.

Autonomous flight of miniature UAVs demands high performance actuators satisfying the requirements of modern control algorithms. Specially for quadrotors, where lift and control forces are the result of a synchronized action of the four BLDC/propeller actuators, the form of their propellers are fundamental to attain a fast and reliable dynamic response. In this paper, we present a mathematical model of the thrust and the Load-Torque produced by a small scale propeller used in miniature quadrotors in terms of the geometric properties of the blade assuming an operation in hover mode. This model is intended to provide a useful expression for simulation analysis with design purposes. The model is based on the Blade Element Theory and the Euler equation for fluids, and describes the Lift on a thin and curved airfoil with a known angle of attack, as the normal acceleration between the deflected streamlines of an incompressible fluid. This allows the calculation of the thrust and the Load-Torque of a turning propeller in terms of the geometric parameters of its blades, i.e. radial and cross section length, curvature and angle of attack, but preserving the conventional results relating the thrust to a square function of the rotational speed of the propeller. As a reference, we include the conventional model based on experimental coefficients of Lift and Drag before introducing our approach, and then, we illustrate the advantage of our approach with an example based on a propeller with blades of fixed and constant pitch angle and constant width, and finally, we briefly discuss about the evidence, based on experimental and simulation data obtained in the literature, that validates our approach.

VSC based converters are among the most preferred interfaces to perform the interconnection, especially for integration of distributed energy sources, active filtering, and power supply applications. Hysteresis current control presents very attractive characteristics for these applications such as: robust control, fast dynamical response, built-in over-current protection and simple and reliable implementation. However, its highly nonlinear nature have been represented a challenge for the proposal of mathematical models to perform analysis and design tasks. This paper proposes a novel modeling approach based on the accurate calculation of the switching times for time and frequency analyses for grid interconnected hysteresis current controlled VSC converters. From this proposal, analytic formulations in the time domain and frequency domain of the harmonics generated by the controller are drawn. These can be useful to develop analysis and practical design methodologies based on numerical methods.

The photovoltaic (PV) power generation systems have a variable efficiency due to mismatching conditions, such as a partial shading condition. To compensate this situation, the Maximum Power Point Tracking (MPPT) systems are used to search the operating point that results in a maximum power extraction from the PV system. Thus, the present paper proposes and analyses an alternative to the well-known MPPT algorithm Perturb & Observe (P&O), which is based on the bisection numerical method. In this way, the efficiency and tracking speed of the modified P&O can be greatly improved as illustrated in the numerical evaluation presented in this paper.
