  • 5G 위치 추적 시스템 영상 +강의담기

    학문/산업 분야별 ▶ IT 융합 ▶ 세미나 및 튜토리얼

     

    The ability of nodes in a wireless network to be aware of their position continues to become more important for future applications and use cases like the Industrial Internet of Things. Positioning using cellular networks continues to draw attention as a mean to realize those future applications. New Radio (NR) provides many opportunities to use cellular networks to incorporate positioning solutions into those networks. In this seminar, the RAT-dependent solutions expected in 5G Rel-16 are introduced. 5G usecases requires centi-meter localization estimation accuracy, signal processing approaches for high localization accuracy are discussed.

  • Quantum-dot based NIR/SWIR Image sensor 영상 +강의담기

    학문/산업 분야별 ▶ IT 융합 ▶ 세미나 및 튜토리얼

    Image sensors are being used in a wide range of applications from consumer electronics to automotive industries. While Silicon has dominated the market by now, thin-film materials are a promising alternative for the NIR/SWIR imaging as they have higher absorption coefficient in this spectrum while can be monolithically integrated directly on top of a Silicon read-out IC (ROIC) wafer. Such an integration allows to manufacture high resolution infrared image sensors at lower cost compared to the resolution-limited III-V based sensors.

  • Introduction to wind turbine dynamics and innovative rotor design 영상 +강의담기

    학문/산업 분야별 ▶ IT 융합 ▶ 세미나 및 튜토리얼

    A global goal of holding warming well below 2on pre-industrial averages and to pursue efforts to limit temperature increase to 1.5were agreed from the Paris Climate Agreement, COP21. The United Kingdom set the renewable energy target that 15% of energy will be provided by renewable energy sources by 2020. Especially, 30% electricity will be produced by renewable sources such as wind, solar, bio, hydro etc.

    The UK is the world leader in offshore wind energy. In total 31 offshore wind farms are operating where 6.8GW from 1,753 turbines installed are produced which is equivalent of 4.5milion homes annual electricity consumption. Moreover, the world first floating wind farm is installed in the UK, called Hywind Scotland, a total capacity of 60MW.

    Most recently, GE announced that they will produce a 12MW offshore wind turbine which has 220m rotor diameter. It is the world largest wind turbine. In order to increase the electrical power output, it is essential to increase the rotor diameter. However, increasing rotor diameter results in increasing the total weight of the rotor. Generally, a wind turbine power is proportional to the square of the blade length while a weight of the blade is proportional to the cube of its length. A heavy wind turbine blade makes all other wind components heavier such as hub, nacelle, tower, and substructures resulting in less cost efficient. Therefore, in order to increase the wind turbine size without increasing the cost of the energy, innovative design via technology breakthroughs are required.

    In this seminar, I will provide two lectures. For the first lecture, I will cover fundamental theory of wind turbine system (Blade Element Momentum Theory) and introduce basic terminology of each wind turbine component which helps audiences to understand basics of wind turbine system. In the second lecture, I will present some of state-of-the-art technologies in both on- and off-shore wind turbine, which can tackle technical challenges to improve the wind turbine performances resulting in the cost of energy reduction even further. More specifically, I will introduce a study to design aeroelastically tailored blades based on geometric coupling such as a swept blade, which can reduce the vibrations of the wind turbines and increase the annual energy production. I will also present an innovative design study to replace active pitch control system with a passive system driven by centrifugal force or force imbalance between torque and thrust on the rotor. Finally, I will briefly talk about dynamic behaviors of a floating wind turbine system with different control strategies where I performed both numerical and experimental studies with a scaled DTU 10MW reference wind turbine with a tension leg platform.

  • Modelling of Bionic Manipulators 영상 +강의담기

    학문/산업 분야별 ▶ IT 융합 ▶ 세미나 및 튜토리얼

    The Biomimetic science consists in understanding some natural behaviours and to reproduce their functioning. The main issue of the bionic research is to find the most adapted technology imitating a nature behaviour. Among the different kind of bionic robots, a class of the continuum robots characterized by a constant curvature are often used to describe a biological elephant trunk. Determination of forward and inverse kinematics of such robots is always difficult, since these robots are characterize by infinite degrees of freedom. An accurate dynamic model of these class of robots can help in developing satisfactory model based control scheme. The talk will discuss forward and inverse kinematics of bionic manipulators.

  • Beyond the acoustic diffraction limit: Super-resolution Ultrasound Imaging 영상 +강의담기

    학문/산업 분야별 ▶ IT 융합 ▶ 세미나 및 튜토리얼

    The recently introduced super-resolution imaging technique based on microbubble center localization has shown potential to achieve unprecedented high spatial resolution beyond the acoustic diffraction limit. However, a major drawback of the current super-resolution imaging approach is low temporal resolution because it requires a large number of imaging frames. In this talk, a new imaging sequence and signal processing approach for super-resolution ultrasound imaging are presented to improve temporal resolution by employing deconvolution and spatio-temporal-interframe-correlation based data acquisition and motion compensation. The proposed method not only identifies a tiny vessel with a diameter of 41 μm, 5 times higher spatial resolution than the acoustic diffraction limit at 7.7 MHz, but also significantly improves temporal resolution that allows for imaging vessels over cardiac motion.

  • Deep Learning in Biometry 영상 +강의담기

    학문/산업 분야별 ▶ IT 융합 ▶ 세미나 및 튜토리얼

     In the recent years we are witnessing a dominance of deep neural network learning approach in the machine learning field. Eventhough the neural network concept is more than 50 years old, only the recent developments enabled its wide use. Namely, availability of processing power, especially graphical processing units, availability of large databases, and the refined knowledge about the approach itself. Convolutional neural network as a special case of deep learning approach is widely used in computer vision domain, also in biometry. A lot of image material is obtained through surveillance scenarios, where we can use modalities like face, gait, and ears for recognition, normally within a multibiometrics system. Each modality has to be first detected and then recognized. The following examples are discussed in this context: 1) network for ear detection in the wild, where, different from competing techniques from the literature, our approach does not simply return a bounding box around the detected ear, but provides accurate and detailed, pixel-wise information about the location of the ears in the image; 2) training network with limited training data for ear recognition in the wild, where we explore different strategies towards model training with limited amounts of training data and show that by selecting an appropriate model architecture, using aggressive data augmentation, and selective learning on existing (pre-trained) models, we are able to learn an effective model; 3) face deidentification (anonymization) with generative network that provides privacy guaranties and at the same time retains certain important characteristics of the data even after deidentification.
