Modeling, Identification, Estimation and Adaptation for the Control of Power-Generating Kites
(2018)IFAC-PapersOnLine ~ 18th IFAC Symposium on System Identification, SYSID 2018. ProceedingsLarge-scale kites, flying high-force crosswind trajectories, have been proposed for wind power generation. A two phase operational cycle generates net positive power using a ground-based motor/generator. In the traction phase the kite flies a high-force trajectory while reeling out the generator-connected tethers. A low-force retraction phase reels in the tethers and returns the kite to the start of the cycle. Highly variable conditions ...Conference Paper -
Experimental And Numerical Investigation Of Blade Resonance In A Centrifugal Compressor For Varying Gas Properties
(2018)GPPS Montreal18 ProceedingsThe blades of centrifugal compressors are exposed to unsteady forces during operation which can result in resonance response conditions and failures due to high cycle fatigue. A typical source of excitation is the unsteady fluid structure interaction between the impeller blades and the downstream vaned diffuser. Centrifugal compressors are operated with various working fluids with a wide range of applications in the power and process ...Conference Paper -
Adaptive Tutoring on a Virtual Reality Driving Simulator
(2018)International SERIES on Information Systems and Management in Creative EMedia (CreMedia)We propose a system for a Virtual Reality (VR) driving simulator including an Intelligent Tutoring System (ITS) to train the user's driving skills. The VR driving simulator comprises a detailed model of a city, Artificial Intelligence (AI) traffic, and a physical driving engine, interacting with the driver. In a physical mockup of a car cockpit, the driver operates the vehicle through the virtual environment by controlling a steering ...Conference Paper -
Cristal and Azurite: new tools for integration-by-parts reductions
(2018)PoS: Proceedings of ScienceScattering amplitudes computed at a fixed loop order, along with any other object computed in perturbative quantum field theory, can be expressed as a linear combination of a finite basis of loop integrals. To compute loop amplitudes in practice, such a basis of integrals must be determined. We discuss Azurite (A ZURich-bred method for finding master InTEgrals), a publicly available package for finding bases of loop integrals. We also ...Conference Paper -
Measuring the Optical Point Spread Function of FACT Using the Cherenkov Camera
(2018)PoS: Proceedings of ScienceFACT, the First G-APD Cherenkov Telescope, is an Imaging Air Cherenkov Telescope (IACT) operating since 2011 at the Observatorio del Roque de los Muchachos on the Canary Island of La Palma. As typical for IACTs, its reflector is comprised of smaller mirror facets and not protected by a dome. In the case of FACT, 30 hexagonal facets form a total mirror area of 9.5 m 2 . Hence, it is crucial to monitor the optical properties of this ...Conference Paper -
LandRate toolbox: An adaptable tool for eye movement analysis and landscape rating
(2018)Eye Tracking for Spatial Research, Proceedings of the 3rd International WorkshopThe paper presents a new software tool called LandRate toolbox. The toolbox constitutes an extension of EyeMMV toolbox and supports the generation of a full analysis report based on experimental data collected through eye tracking methods. Additionally, a new aggregated index (LRI), appropriate for the performance of landscape rating procedures, is introduced. The index combines both quantitative eye tracking metrics and experts’ opinions ...Conference Paper -
Risk Perception and Gaze Behavior during Urban Cycling – A Field Study
(2018)Eye Tracking for Spatial Research, Proceedings of the 3rd International WorkshopWe investigated the relation of risk perception and gaze behavior during urban cycling in a naturalistic real world setting. Participants rode a bike on five route segments while wearing a mobile eye tracking device, and subsequently marked, described, and rated all areas they thought to be dangerous. Their gaze was focused on the areas they marked as potentially dangerous. The participants’ gaze was also more focused on areas they felt ...Conference Paper -
Evaluating frequency regulation operated on two stationary energy systems with batteries from electric vehicles
(2018)Energy Procedia ~ 12th International Renewable Energy Storage Conference, IRES 2018Two medium-sized stationary energy storage systems of 55 kW and 120 kW, built from repurposed BMW i3 batteries, comprise the basis of this study. Giving a supplementary overview of applications for lithium-ion based energy storage systems, this paper focuses on the operational behaviour of the two systems for a frequency regulation application. A new analysis method for assessing system and battery pack behaviour is presented. Then the ...Conference Paper -
Development of three-dimensional strut-and-tie models for structural concrete components
(2018)Proceedings of the 12th fib International PhD Symposium in Civil EngineeringThis paper presents a proposal for developing a procedure for the generation of 3D strut-and-tie models for structural concrete components, using the techniques of topology optimization and graphical statics. Extensive research has been carried out on the development of methodologies to generate strut-and-tie patterns based on the flow of stresses within a structural volume. Some focus on the various formulations of topology optimization ...Conference Paper
