High efficiency and low costs are requirements for any industrial plant. Advancements in digital technology and integrated components have made it easier to incorporate device level communications and intelligence into any design. Intelligent motor control is not a new concept; intelligent devices are mature technologies accepted throughout industry with well-documented benefits. This paper outlines a less well-documented area: teaching motor control and protection theories through the interactions of a fully integrated, standards-compliant, intelligent motor control center. As well this paper provides a framework for students to learn about the technical requirements and design specifications for building a state-of-the-art Intelligent Motor Control Center (IMCC).

850-nm vertical-cavity laser diodes with copper-plated heat sinks were fabricated and tested. Vertical-cavity surface-emitting lasers with 10μm aperture diameter and 4μm of electroplated copper demonstrated a maximum -3dB modulation bandwidth of more than 16GHz and a resonance frequency of more than 11GHz at bias current of only 5.4mA, which correspond to a bias current density of only 7.5kA/cm 2 . Thus, reported devices exhibited a high -3dB modulation bandwidth squared over bias current density ratio of more than 35GHz 2 /kA/cm 2 . The displayed 7.5 kA/cm 2 bias current density is less than the 10 kA/cm 2 current density standard for reliability by 25%. Devices also demonstrate a reduced thermal resistance of 1.01 °C/mW, a threshold current of 1.1mA, a series resistance of only 60Ω, and a maximum output power density of about 1.2mW/cm 2 .

In this paper, a method for further reducing computation time for Fast Look-Ahead Rao-Blackwellized Particle filtering (Fast la-RBPF) for Simultaneous Localization and Mapping (SLAM) problem is presented. By using the pose posterior probability, states with low posteriors are excluded from the Kalman filtering updates to the computation time can be reduced. In conjunction with Fast la-RBPF, the proposed algorithm is then called the Posterior Elimination Fast la-RBPF SLAM algorithm. Simulation results show that the proposed method is more efficient in terms of computation time than Fast la-RBPF without any sacrifice in both localization and mapping error performances.

In EMTP, it is very hard to simulate a vertically arranged cable, since its surge impedance gradually changes with the distance from the ground to a top point. In the past, some researches about surge impedances and responses of vertical conductor (for example transmission tower, concrete pole and so on.) have been carried out, these researches are being continued now. However, there is no model of vertical co-axial cable in EMTP. In order to analyze surge voltage arisen on the electrical system, approach of method for treating this model in EMTP is required. In this paper, experiments of surge impedance and response on vertical cable, method of treating for vertical co-axial cable in EMTP and accuracy confirmed as compared result of this model with analysis result of VSTL Rev. (Virtual Surge Test Lab. rev.) which is constructed under FDTD (Finite Difference Time Domain) method, are reported. © 2016 The Institute of electrical Engineers of Japan.

The Winter Colloquium on the Physics of Quantum Electronics (PQE) has been a seminal force in quantum optics and related areas since 1971. It is rather mindboggling to recognize how the concepts presented at these conferences have transformed scientific understanding and human society. In January, 2017, the participants of PQE were asked to consider the equally important prospects for the future, and to formulate a set of questions representing some of the greatest aspirations in this broad field. The result is this multi-authored paper, in which many of the world's leading experts address the following fundamental questions: (1) What is the future of gravitational wave astronomy? (2) Are there new quantum phases of matter away from equilibrium that can be found and exploited-such as the time crystal? (3) Quantum theory in uncharted territory: What can we learn? (4) What are the ultimate limits for laser photon energies? (5) What are the ultimate limits to temporal, spatial, and optical resolution? (6) What novel roles will atoms play in technology? (7) What applications lie ahead for nitrogen-vacancy centers in diamond? (8) What is the future of quantum coherence, squeezing, and entanglement for enhanced superresolution and sensing? (9) How can we solve (some of) humanity's biggest problems through new quantum technologies? (10) What new understanding of materials and biological molecules will result from their dynamical characterization with free electron lasers? (11) What new technologies and fundamental discoveries might quantum optics achieve by the end of this century? (12) What novel topological structures can be created and employed in quantum optics?

Gliomas are the most common primary brain malignancies, with different degrees of aggressiveness, variable prognosis and various heterogeneous histologic sub-regions, i.e., peritumoral edematous/invaded tissue, necrotic core, active and non-enhancing core. This intrinsic heterogeneity is also portrayed in their radio-phenotype, as their sub-regions are depicted by varying intensity profiles disseminated across multi-parametric magnetic resonance imaging (mpMRI) scans, reflecting varying biological properties. Their heterogeneous shape, extent, and location are some of the factors that make these tumors difficult to resect, and in some cases inoperable. The amount of resected tumor is a factor also considered in longitudinal scans, when evaluating the apparent tumor for potential diagnosis of progression. Furthermore, there is mounting evidence that accurate segmentation of the various tumor sub-regions can offer the basis for quantitative image analysis towards prediction of patient overall survival. This study assesses the state-of-the-art machine learning (ML) methods used for brain tumor image analysis in mpMRI scans, during the last seven instances of the International Brain Tumor Segmentation (BraTS) challenge, i.e., 2012-2018. Specifically, we focus on i) evaluating segmentations of the various glioma sub-regions in pre-operative mpMRI scans, ii) assessing potential tumor progression by virtue of longitudinal growth of tumor sub-regions, beyond use of the RECIST/RANO criteria, and iii) predicting the overall survival from pre-operative mpMRI scans of patients that underwent gross total resection. Finally, we investigate the challenge of identifying the best ML algorithms for each of these tasks, considering that apart from being diverse on each instance of the challenge, the multi-institutional mpMRI BraTS dataset has also been a continuously evolving/growing dataset.

In this paper we present a controller that achieves global input-to-state stability for a linear system of arbitrary relative degree, subjected to matched and unmatched disturbances. This controller combines the properties of a discontinuous term, and a linear one, enforcing a conventional sliding mode using only partial state information. A direct and simple way of choosing the gains for this controller is also provided.

International Conference on Modeling, Simulation and Applied Optimization (ICMSAO)

作者： Fitri Arnia Khairul Munadi Graduate Program in Electrical Engineering Syiah Kuala University Indonesia Department of Electrical Engineering Faculty of Engineering

This paper proposes a framework for textile defect detection on the basis of energy and contrast features of the gray-level co-occurrence matrix (GLCM). We calculate these features in DCT-based compressed image (DCTb-I), which was produced by using only a small number of DCT coefficients. The proposed detection approach complies with the Moving Picture Experts Group (MPEG) and Motion Joint Photographic Experts Group (MJPEG) video compression standards, which improves the defect detection efficiency, in terms of space and computational cost by replacing the frame grabbers with MPEG encoders and by only considering I-frames in the MPEG or specific frames in the MJPEG sequence. We determine (1) the detection accuracy of using DCTb-Is with various compression rates, and (2) the lowest DCTb-I rates that allow defect detection. The DCTb-Is are tiled into blocks from which the energy and contrast features are calculated. The highest energy and lowest contrast blocks are detected and located in the textile as defects. The proposed approach is suitable for real-time detection because, unlike common defect-detection approaches, prior feature extraction from reference images is not required. Simulation results suggest that holes, stains and drop stitches can be detected and located from DCTb-Is if the compression rate is greater than 25%.

This article aims to introduce a software tool for induced voltages and currents calculation inside structure caused by electromagnetic field radiated by lightning strike to PV systems which are installed on the top of the structure. The methodology used in the calculation is accordance with standard IEC 62305 - 4: 2010. This program has been developed to determine electromagnetic field, induced loop voltages and currents in a lightning protection zone 1 (LPZ 1). As a result, the software is very useful in calculation of induced over-voltage and current and helps engineers in lightning protection design.
