IEEE International Conference on DC Microgrids (ICDCM)

作者： Thiago R. de Oliveira Pedro F. Donoso-Garcia Graduate Program in Electrical Engineering UFMG Belo Horizonte MG Brazil Department of Electronics and Biomedics CEFET-MG Belo Horizonte Brazil Department of Electronic Engineering UFMG Belo Horizonte Brazil

The main purpose of this paper is to discuss possible means for DC distribution adoption in Brazil in medium term, basing the discussion on the perspective of an emerging country. A main path to be explored is the progressive adaptation of PV residential and commercial distributed generation systems into a DC microgrid, allowing energy efficiency, power quality and energy management improvements. A DC microgrid testbed in current development in the Federal University of Minas Gerais (UFMG) will also be described and simulated results will be used to demonstrate the behavior of the proposed architecture.

Thermoelectric (TE) modules are solid-state devices that convert directly thermal energy in electrical energy. However, they can undergo performance degradation due to thermal cycling. In the present study, a control-based test platform that is capable to apply specific thermal cycling pattern at periodic intervals is presented in order to evaluate performance degradation that influence the TE module lifetime. Using this test platform, some parameters and the figure of merit ZT of a commercial TE module are measured before and after thermal cycling application. An important feature of the proposed platform is that the applied thermal cycling is bipolar, that is, it is possible to apply positive or negative temperature difference and, through this, performance degradation would be observed after only 548 thermal cycles much lower than previous works.

Automated segmentation of different tissues on medical images is a crucial concept for medical image analysis. In this study, unsupervised image segmentation problem is generalized as a Mumford-Shah energy minimization problem, and several solution proposals for the problem are investigated. Ambrosio-Tortorelli approximation method is implemented, and the performance of the algorithm on magnetic resonance (MR) images of brain is evaluated. First image used in the experiments is chosen among the ones which contain an edema formation due to a brain tumor, and the second one belongs to a healthy subject on which gray matter/white matter segmentation is aimed. Acquired results are presented in visual, tabular and numerical forms. Results and performance are discussed and quantitatively evaluated. © Springer International Publishing Switzerland 2014.

This paper presents the comparation of three different feature extraction techniques based on the Empirical Mode Decomposition (EMD) for a SSVEP-BCI. This approach based on the characterization of the signal by EMD, is proposed as a novel alternative to other techniques and it was demonstrated that it exceeds both in accuracy rate and Information Transfer Rate (ITR). The experiments were performed in an offline way, and seven volunteers participated of the study. The stimulis were generated both by LCD and LEDs. The frequencies used were 8, 11, 13 and 15 Hz. The results here reported such represent the average of the seven participants, achieving a success rate of 81% and ITR of 23.32 bits/min of the total set of cases analyzed. It is further confirmed that the highest success rates and ITRs were obtained for stimulation by LEDs.

This paper presents the evaluation of seven techniques of feature extraction (PSD, F-Test, EMD, MCE, CCA, LASSO and MSI) for gaze-target detections in a SSVEP-based BCI. Two type of technologies for visual stimulation were used (LCD and LEDs). Five differents windows lengths (1, 2, 4, 5 and 10 s) were used and seven volunteers participated in this study. The highest accuracy obtained in all cases was 93.57% using LEDs and the highest ITR was 36.90 bits/min for LCD. The technique based on MSI shows the highest success rate in both cases (LCD or LED) and is even more noticeable when the window size is increased.

Background: Surveillance of health care-associated infections is an essential component of infection prevention programs, but conventional systems are labor intensive and performance dependent. Objective: To develop an automatic surveillance and classification system for health care-associated bloodstream infection (HABSI), and to evaluate its performance by comparing it with a conventional infection control personnel (ICP)-based surveillance system. Methods: We developed a Web-based system that was integrated into the medical information system of a 2200-bed teaching hospital in Taiwan. The system automatically detects and classifies HABSIs. Results: In this study, the number of computer-detected HABSIs correlated closely with the number of HABSIs detected by ICP by department (n=20;r=.999 P<.001) and by time (n=14;r=.941;P<.001). Compared with reference standards, this system performed excellently with regard to sensitivity (98.16%), specificity (99.96%), positive predictive value (95.81%), and negative predictive value (99.98%). The system enabled decreasing the delay in confirmation of HABSI cases, on average, by 29 days. Conclusions: This system provides reliable and objective HABSI data for quality indicators, improving the delay caused by a conventional surveillance system. © 2020 JMIR Publications Inc.

Considered that the dual band sensor system is the most popular design at present, this study discussed the design of a dual-band hybrid array readout circuit. The direct injection circuit structure was used in the unit pixel. The design, simulation, and layout were conducted in the 40um×40um unit pixel to complete middle and long waveband signal readouts, in order to achieve one sensor unit with two sensor modes. The readout circuit chip adopted TSMC 0.35um 2P4M CMOS 5V to design a 16×12 array readout circuit, with an input current range of the measured current at 1.9pA to 50 nA, an adjustable integration time, a maximum frame rate of 110Hz, the output swing of the chip signal of 2V, the maximum operating chip frequency of 3MHz, power dissipation of 18mW, system noise voltage Vrms of 0.68mV, and signal-noise ratio of 69dB. Finally, the tested chip was used to connect the detection system proxy board and digital signal board, and digital signal processing video through front-end filters and analog to digital converter, in order to complete signal conversion and digital signal processing. With the digital control signal provided by the signal board and signal capture, the back-end digital signal was processed and imaged on the screen. The readout circuit chip connected the signal proxy board for testing. The overall system resolution reached 10 bit.
