Vein biometrics is emerging and gaining popularity over other types of biometric systems due to its strengths of low forgery risk, aliveness detection, non-invasive data acquisition as well as stable over long period. This paper presents a novel design of an embedded finger vein biometric recognition hardware system targeted for implementation on a field-programmable gate array (FPGA) platform. A novel streaming architecture for hardware acceleration of window-based image processing application is proposed. To ensure high quality image capture and high recognition accuracy, we introduce an image acquisition subsystem that uses an embedded camera with dynamic illumination based on quality assessment. Experimental results show that the proposed finger vein verification system achieves 0.87% equal error rate (EER) on a database of 500 finger vein images.

This article presents a system for tracking the position of objects within a smart home to support a robot assistant in pick-and-place tasks. The current system is capable of estimating the position of an object using the signal strength received by a mobile device in a ZigBee sensor network. Received strength signal indication measurements were done in laboratory for applying a estimation method. Two models were utilized (a) log-distance path loss - model in which signal lost has a random influence with log-normal distribution, and (b) free space decay law - based on the decay law for a signal on a open space. Experiments with satisfactory results were done with a public dataset to benchmark our data.

This manuscript describes the identification process of the parameters of the Jiles-Atherton-model (JAM) which can be used to characterize the magnetic behavior of electrical steel sheets. A simple semi-analytic parameter identification process using only a small set of symmetrical hysteresis loops is proposed, which requires low computational effort in contrast to the intensive numerical optimization algorithms which are normally used to gain the JAM parameters. Finally some aspects concerning the representation of minor loops will be discussed.

This paper analyzes and studies the methods of reducing torque pulsation in interior permanent magnet (IPM) machines with fractional-slot concentrated-winding (FSCW) for hybrid electric vehicles. Several methods are proposed to reduce the cogging torque and ripple torque for the IPM machine. Two finite element analysis (FEA) models of the IPM machine, including FSCW and integer-slot distributed windings, are studied in order to verify the proposed method. Finally, the performance of the machine with these two windings, including the flux-weakening capabilities, is compared. The comparison results show that the machine with FSCW has lower torque pulsation and wider speed range of constant power than the machine with integer-slot winding.

This paper describes the integration of a Type-I Internal Model Converter (IMC) with the Takagi-Sugeno Fuzzy (TS) modeling technique of a boost converter, in order to control the output of this DC-DC converter. The IMC used in this work adds an integrator to the TS local models, which allows the tracking of step references, according to the internal control principle. Linear matrix inequalities (LMIs) are used to calculate the local controllers, in order to guarantee an asymptotic stability, robustness against variation in the parameters and set the dynamics of the closed-loop control system. Simulation and experimental results proves that the proposed control technique have a good performance and a negligible steady-state error for step references.

High-voltage direct current system using modular multilevel converter (MMC-HVDC) is a potential candidate for grid integration of renewable energy over long distances. The dc-link fault is an issue MMC-HVDC must deal with. This paper proposed an enhanced MMC topology with dc fault ride-through capability. By using diode clamp sub-modules, the freewheeling effect of diodes is eliminated and fault currents can be very rapidly extinguished. Since the tripping of circuit breakers is avoided, MMC can immediately restart power transmission for non-permanent faults. The required rated voltage of additional semiconductors is half the conventional semiconductors, resulting in low extra cost. Simulation results using PSCAD/EMTDC have verified the validity of the proposed protection scheme.

The deployment of Simulation-aided Building Controls is a complex process due to the uniqueness of each building along with an increasing complexity of building systems. Typically the deployment tasks are performed manually by highly specialized personnel which results in a poorly documented and extremely scattered deployment process. This paper introduces a workflow for the deployment of a Simulation-aided Building Control service suitable for supporting the operation phase of a building. Some tasks in the deployment process may benefit from machine support, especially data intensive, repetitive and error prone tasks. These may be fully or semi-automated. The proposed approach reduces the complexity of the setup procedure, decreases problems related to the uniqueness of the infrastructure and supports the documentation of the deployment process. Specially large facility management service providers may profit from this deployment process.

This work presents a control strategy for the cascade asymmetric multilevel converter (CAMC). The analysis of the switching states of the topology is perfomed. A new voltage ratio for the phase capacitor, which splits redundant states and expands the number of levels from five to seven, is proposed. This improves the harmonic profile of the output voltage without additional switching devices. A Finite-states model predictive controller (FS-MPC) that uses simple dynamic models, jointly with properly defined cost functions performs the regulation of the internal voltages of the converter (phase capacitors and DC bus capacitors) and the line currents of a three phase load.

Contactless power transmission (CPT) technique based on the contactless transformers is extraordinarily promising for the electrical vehicle (EV) battery charging application for its safety, convenience and flexibility. By introducing two parallel windings into two EV CPT charging systems so as to constitute two cascaded contactless transformers, a novel contactless bidirectional resonant converter (CBRC) is proposed in this paper. Based on which, an emergency battery charging system is also presented. The equivalent circuit of the cascaded contactless transformers and the topology of the CBRC are analyzed and discussed in this paper and the series-series compensated double full bridge CBRC is finally adopted as the main circuit. This paper takes a thoroughly study on the control strategies for the proposed CBRC. After proposing and analyzing three possible control methods, primary constant frequency plus secondary PWM control and primary PLL and PWM control are adopted. Finally, an 1800 W CBRC prototype with two control methods is fabricated to verify the theoretical analysis and the effectiveness of the proposed control strategies.

Many components of a modern micro grid operate using a dc interface including solar panels, fuel cells, and battery energy storage. For this reason, a dc micro grid has been suggested and utilized in some power systems. With the absence of a zero-crossing in the current waveform, the dc breaker faces a unique challenge in that there is no natural method of extinguishing an arc that occurs during breaker operation. This is handled in practice by using over-sized ac breakers, using a solid-state breaker, or using a hybrid solid-state/mechanical breaker. A recently introduced z-source breaker is a unique form of the solid-state breaker that automatically reacts in real-time to system faults; not requiring the typical fault sensing and detection. It has the ability to clear the fault within microseconds. Furthermore, the source will not experience the fault current. In this paper, the theory behind the z-source breaker is reviewed and the breaker is studied in the context of several micro grid topological arrangements using non-real-time and real-time simulation.
