description: Durch den technischen Fortschritt der letzten Jahre rücken Augmented Reality – Anwendungen (AR) als Lernmedien immer mehr in den Fokus der aktuellen Lehr-Lern-Forschung. Aus didaktischer Sicht besitzt AR als Lernmedium Potenziale, die es von bisherigen Medien unterscheidet. Andererseits ergeben sich durch die Nutzung von AR jedoch auch neue Herausforderungen, die noch zu lösen sind. Am Beispiel eines konkreten Lernszenarios werden die didaktischen Potenziale von AR vorgestellt und die sich ergebenden Herausforderungen beschrieben. Das Lernszenario wurde mit Hilfe der App AugView realisiert und in die Lehre im Fachbereich Umweltingenieurwesen integriert. Die App stellt im Untergrund verborgene leitungsgebundene Wasserinfrastruktur dar. Zu den positiven didaktischen Eigenschaften zählt u.a. die zeitlich und örtlich kohärente, gemeinsame Darstellung von Objekt und erklärenden Zusatzinformationen (Kontiguitätsprinzip). Durch kollaboratives Arbeiten mit der App im Rahmen von Exkursionen wird situatives Lernen und gemeinsame Wissenskonstruktion gefördert. Zu den ungelösten Herausforderungen zählt aktuell noch der technische Aufwand. Da die GPS-Positionierung auf handelsüblichen Tablets nicht ausreichend genau ist, sind vergleichsweise teure Zusatzsysteme zur exakteren Positionierung notwendig. Weitere Herausforderung ist der Datenschutz. Digitale Repräsentationen der Leitungsnetze sind zwar beim lokalen Versorger vorhanden. Jedoch gibt es Sicherheitsbedenken, diese für die Lehre vollständig öffentlich verfügbar zu machen.

Publisher: name: aw&I Conference
Year: 2018

description: Überwachungstätigkeiten in Leitständen der Automobilproduktion sind durch die Beobachtung von Anlagendaten gekennzeichnet. Ein Erfolgsfaktor für eine effiziente Produktion ist, dass Operateure auftretende Störungen im Leitstand schnell erkennen und beheben. Die hierfür nötige Dauerbeobachtung ist für die Operateure eine Herausforderung. Cummmigs, Gao und Thornburg (2016) haben beobachtet, dass bei einer geringen Arbeitsbelastung die Aufmerksamkeit der Operateure bei der Überwachung von automatisierten Systemen mit der Zeit abnahm. Zum anderen müssen die Operateure ein gutes Situationsbewusstsein über Veränderungen ihrer Anlage haben, um Störungen schnell beheben zu können.


In diesem Beitrag werden Ergebnisse einer Interviewstudie zur Untersuchung psychischer Bedürfnisse in der Mensch-Technik-Interaktion an Leitständen beschrieben. In 20 semi-strukturierten Experteninterviews wurden Operateure nach beanspruchenden und intrinsisch motivierenden Faktoren bei Überwachungstätigkeiten befragt. Die Ergebnisse zeigen die zentralen Nutzerbedürfnisse der Operateure auf, mithilfe deren in Folge motivierende Nutzerelemente für den Leitstand der Zukunft entwickelt werden sollen.

description: This paper deals with Networked Control Systems (NCSs) whose shared networks have limited communication capacity and are prone to data losses. We assume that among (N) plants, only (M < N) plants can communicate with their controllers at any time instant. In addition, a control input, at any time instant, is lost in a channel with a probability (p). Our contributions are threefold. First, we identify necessary and sufficient conditions on the open-loop and closed-loop dynamics of the plants that ensure existence of purely time-dependent periodic scheduling sequences under which stability of each plant is preserved for all admissible data loss signals. Second, given the open-loop and closed-loop dynamics of the plants, relevant parameters of the shared network and a period for the scheduling sequence, we present an algorithm that verifies our stability conditions and if satisfied, designs stabilizing scheduling sequences. Otherwise, the algorithm reports non-existence of a stabilizing periodic scheduling sequence with the given period and stability margins. Third, given the plant matrices, the parameters of the network and a period for the scheduling sequence, we present an algorithm that designs static state-feedback controllers such that our stability conditions are satisfied. The main apparatus for our analysis is a switched systems representation of the individual plants in an NCS whose switching signals are time-inhomogeneous Markov chains. Our stability conditions rely on the existence of sets of symmetric and positive definite matrices that satisfy certain (in)equalities.

description: Freshwater flooding is the number one inland killer associated with hurricanes that make landfall in the Mid-Atlantic region. Although great improvements in hurricane track forecasting have been made over the past decade, forecasting hurricane intensity change and rainfall has remained problematic. This challenge becomes even more difficult after the storm makes landfall. Over land, storms typically weaken; however, strong nonlinear interactions with mid-latitude systems or forcing from terrain can reintensify the storm or trigger extreme precipitation events. The goal of the work presented here is to better understand the physical processes that lead to heavy precipitation and storm reintensification during the extratropical transition of hurricanes in the Mid-Atlantic region. We use the North American Regional Reanalysis to analyze in detail two landfalling storms: Hurricane Gaston (2004) and Hurricane Ernesto (2006). Both storms presented forecast challenges and both resulted in heavy precipitation, although through different mechanisms. Gaston was shown to create its own baroclinic zone, which led to heavy rainfall and latent heat release which allowed the storm to briefly rejuvenate over land. Ernesto interacted strongly with an upper level trough and jet, which created a secondary circulation that fueled the storm with moisture from the Atlantic. A potential vorticity analysis shows evidence for a case of stolen identity and possible stratosphere-troposphere exchange (STE). Diabatic forcing in the mesoscale proved to be most important in the transition of Gaston, whereas synoptic scale interactions were crucial to the evolution of Ernesto, which also occluded very quickly. The various spatial scales and rapid transitions of both these storms provide insight into the forecasting challenges during these transition events.

description: A Markovian master equation describing the evolution of open quantum systems in the presence of a time-dependent external field is derived within the Bloch-Redfield formalism. It leads to a system--bath interaction which depends on the control field. Optimal control theory is used to select control fields which allow accelerated or decelerated system relaxation, or suppression of relaxation (dissipation) altogether, depending on the dynamics we impose on the quantum system. The control--dissipation correlation and the non-perturbative treatment of the control field are essential for reaching this goal. The optimal control problem is formulated within Pontryagin's minimum principle and the resulting optimal differential system is solved numerically. As an application, we study the dynamics of a spin-boson model in the strong coupling regime under the influence of an external control field. We show how trapping the system in unstable quantum states and transfer of population can be achieved by optimized control of the dissipative quantum system. We also used optimal control theory to find the driving field that generates the quantum Z-gate. In several cases studied, we find that the selected optimal field which reduces the purity loss significatively is a multi--component low--frequency field including higher harmonics, all of which lie below the phonon cutoff frequency. Finally, in the undriven case we present an analytic result for the Lamb shift at zero temperature.

description: The prevalence and maturity of Bring Your Own Device (BYOD) security along with subsequent frameworks and security mechanisms in Australian organisations is a growing phenomenon somewhat similar to other developed nations. During the COVID 19 pandemic, even organisations that were previously reluctant to embrace BYOD have been forced to accept it to facilitate remote work. The aim of this paper is to discover, through a study conducted using a survey questionnaire instrument, how employees practice and perceive the BYOD security mechanisms deployed by Australian businesses which can help guide the development of future BYOD security frameworks. Three research questions are answered by this study - What levels of awareness do Australian businesses have for BYOD security aspects? How are employees currently responding to the security mechanisms applied by their organisations for mobile devices? What are the potential weaknesses in businesses IT networks that have a direct effect on BYOD security? Overall, the aim of this research is to illuminate the findings of these research objectives so that they can be used as a basis for building new and strengthening existing BYOD security frameworks in order to enhance their effectiveness against an ever-growing list of attacks and threats targeting mobile devices in a virtually driven work force.

description: In this article we study the general structure and special properties of the Schwinger-Dyson equation for the gluon propagator constructed with the pinch technique, together with the question of how to obtain infrared finite solutions, associated with the generation of an effective gluon mass. Exploiting the known all-order correspondence between the pinch technique and the background field method, we demonstrate that, contrary to the standard formulation, the non-perturbative gluon self-energy is transverse order-by-order in the dressed loop expansion, and separately for gluonic and ghost contributions. We next present a comprehensive review of several subtle issues relevant to the search of infrared finite solutions, paying particular attention to the role of the seagull graph in enforcing transversality, the necessity of introducing massless poles in the three-gluon vertex, and the incorporation of the correct renormalization group properties. In addition, we present a method for regulating the seagull-type contributions based on dimensional regularization; its applicability depends crucially on the asymptotic behavior of the solutions in the deep ultraviolet, and in particular on the anomalous dimension of the dynamically generated gluon mass. A linearized version of the truncated Schwinger-Dyson equation is derived, using a vertex that satisfies the required Ward identity and contains massless poles belonging to different Lorentz structures. The resulting integral equation is then solved numerically, the infrared and ultraviolet properties of the obtained solutions are examined in detail, and the allowed range for the effective gluon mass is determined. Various open questions and possible connections with different approaches in the literature are discussed.

Somit wirkt es dreifach: visuell, emotional und biologisch. Die biologische Wirkung des Lichts taktet die innere Uhr des Menschen. Vor allem der dadurch beeinflusste Anteil der Hormone Cortisol und Melatonin im Körper bestimmt Schlaf- und Wachphasen, aber auch Herzfrequenz, Blutdruck und Stimmung.


Lange Zeiten, in denen Menschen heute künstlichem Licht und damit oft biologischer Dunkelheit ausgesetzt sind, machen eine gute Beleuchtung umso wichtiger. Biodynamisches Licht (Human Centric Lighting) kann vor allem in Räumen mit wenig Tageslichtversorgung sowie in den Wintermonaten, wenn die innere Uhr kaum mit dem Tageslicht synchronisiert wird, das Wohlbefinden nachhaltig stärken. Das Waldmann Lichtmanagementsystem VTL entstand in enger wissenschaftlicher Abstimmung. Es bringt die Dynamik des natürlichen Tageslichts in Innenräume und erweitert dadurch die emotionalen und ergonomischen Aspekte der Lichtqualität. Im Büro, in der Industrie und in Pflege- und Gesundheitseinrichtungen.

description: The Author reports on the design and construction of an oxygen spectroscopy laser sounding instrument designed to measure atmospheric pressure. This instrument was conceived and designed with a satellite application in mind so we discuss the requirements this places on the instrument and specifically the laser transmitter. We have developed a novel, pulsed, frequency-doubled, fiber-based laser transmitter for use in the instrument. The instrument concept uses the collision broadening of spectroscopic lines of the diatomic oxygen A-band to deduce atmospheric pressure. We report on the spectroscopic and instrument theory. We discuss the development of a high-power, narrow-frequency, tunable, single spatial mode pulsed laser transmitter. The transmitter is a master oscillator power amplifier (MOPA) design. The master oscillator is a fiber coupled DFB laser with external acousto-optic modulation. The amplifier is a diode pumped, erbium-doped fiber. We discuss the non-linear optical effect of stimulated Brillouin scattering (SBS) and how it limits the transmitter performance. We review various methods for overcoming SBS in erbium fiber amplifiers and then demonstrate the performance of a high SBS threshold fiber amplifier. We demonstrate the efficacy of this transmitter by integrating it into a spectroscopic instrument and make atmospheric measurements at a test site at Goddard. We also discuss future improvements.

Our sample consists of all the CXO< ns of Seyfert-2 galaxies performed using the ACIS-S3 detector during the first 8 years of operation (28 objects). We find extended X-ray emission in all our Seyfert-2 sample of galaxies with a range of luminosities (1038< er>41< >&minus 1< jects, the morphology is predominately bi-conical centered on the nucleus and typically extending out to a few kpc.Only a single cone is seen in 8 of the remaining objects, which may be indicative of intrinsically anisotropic emission. Where data is available, the X-ray cones do appear to occupy the same solid angle as the extended [O III] emission line gas previously detected in these objects. Our data suggest that the luminosity of the extended emission is typically a few percent of that of the nuclear source. Our findings are therefore broadly consist with current theories of AGN, but the low signal to noise for many of the observations combined with obscuration and possible contamination prevent any definitive tests of &ldquo Unified Schemes &rdquo being performed.
Electro-optic Polymer Devices for Terahertz Applications

description: The rapid development of technologies employing terahertz (THz) radiation has led to numerous industrial and scientific applications.   Current THz technologies are limited in their frequency response because of phonon absorbance and poor phase matching in crystalline emitters and detectors, or are limited to high-power bench-top pump laser systems for air-plasma generation and detection.  In contrast, amorphous electro-optic (EO) polymer composite materials have the potential for broad-bandwidth, spectral gap-free THz emission and detection while requiring a relatively low pump laser power. In this thesis a theoretical description of THz radiation emission and detection using EO polymers is reviewed, including the effects of laser spectral bandwidth, pulse distortion, and material properties of the EO media.  This model is used as a guide to improve the response of a THz system employing electro-optic polymer emitters and detectors.   EO polymer composites that have been engineered for terahertz applications are described.  These materials show a progression of improvements for use in THz systems, including higher EO coefficients, increased photostability, and reduced aggregation and dimerization. A study of in-plane (longitudinal) and parallel-plate (transverse) poling of EO polymers for use as THz sensors is presented, including a theoretical description of detection sensitivity for each device.  In-plane poling allows access to the full optical nonlinearity of the EO polymer, potentially increasing detection sensitivity by a factor of 2.4 over parallel-plate poled devices.  A transmission ellipsometric EO measurement technique is developed for the in-plane poling device and is used in the experimental comparison of the two devices. EO polymer composites are employed as terahertz emitters and sensors in systems using communication-wavelength pump lasers.   A 15 THz wideband response is achieved using the ALTB203/APC composite, and is compared to the organic crystal DAST and to the THz system model.  Increasing emitter thickness is studied through stacking multiple EO polymer emitter films.  Frequency-dependent terahertz index and absorption of the emitter and sensor films are included into the THz model for a more accurate representation of the terahertz system response. Given proper phase-matching and low absorption, EO polymer materials can potentially be used in a waveguide geometry to generate broadband THz radiation.  Coupling these devices with currently-available ultra-fast fiber lasers could lead to the development of field-deployable, compact, inexpensive THz systems.

description: The most important accuracy-limiting factor for modern space-based geodetic techniques such as Satellite Laser Ranging (SLR), Very Long Baseline Interferometry (VLBI), the Global Positioning System (GPS), and satellite altimetry is the modeling of atmospheric refraction corrections. SLR uses lasers to measure very precise ranges from ground tracking stations to orbiting geodetic satellites with current single-shot accuracies at the sub-centimeter level.; The current modeling of atmospheric refraction in the analysis of SLR data involves determining the atmospheric delay in the zenith direction and subsequent projection to a given elevation angle, using a mapping function. Improved refraction modeling; is essential in reducing errors in SLR measurements in order to study variations in the Earth's gravity field and crustal motion, as well as monitoring sea-level rise, post-; glacial rebound and other geophysical phenomena. In most of these applications, and particularly for the establishment and monitoring of the International Terrestrial Ref-; erence Frame (ITRF), of great interest is the stability of its scale and its implied height system.; The assumptions of a spherically symmetric atmosphere makes the delay models only dependent on elevation with no dependence on azimuth, and also results in their total failure to account for horizontal refractivity gradient effects. The work in this; dissertation has been based on developing an accurate two-dimensional (2D) and three-dimensional (3D) ray tracing technique, specifically tailored to use globally distributed data from the Atmospheric Infrared Sounder (AIRS), the European Center for Medium Weather Forecasting (ECMWF) and the National Center for Environmental Prediction (NCEP) in order to compute the atmospheric delay, including contributions from horizontal refractivity gradients. We demonstrate the accuracy and effectiveness of the; ray tracing technique by applying the results to a two-year set of global SLR geodetic data with 47,664 observations from the LAGEOS 1 and 2 geodetic satellites. Replacing the delay model with 3D ray tracing significantly reduced the variance of the SLR; solution residuals, a very important result with regard to future improvements of the the accuracy and stability of the ITRF.

description: The field of medicine is difficult to compare between different countries, as the development and their focus are individual and faces unique problems. Possible solutions provided by the western world usually require higher financial expenses and intensive training of workers involved in the medical field. Experience gathered in Mongolia lead to the suggestion that the involvement of computer technology can create benefits for the healthcare sector without extensive costs and intensive training. The missing experience of medical workers can be covered with computed technology that is designed to support them in making correct decisions. At the same time these technologies will never be able to fully replace workers and therefore should not lead to dismissal in the healthcare sector.

description: Dynamical models allow us to connect the motion of a set of tracers to the underlying gravitational potential, and thus to the total (luminous and dark) matter distribution. They are particularly useful for understanding the mass and spatial distribution of dark matter (DM) in a galaxy. Globular clusters (GCs) are an ideal tracer population in dynamical models, since they are bright and can be found far out into the halo of galaxies. We aim to test how well Jeans-Anisotropic-MGE (JAM) models using GCs (positions and line-of-sight velocities) as tracers can constrain the mass and radial distribution of DM halos. For this, we use the E-MOSAICS suite of 25 zoom-in simulations of L* galaxies. We find that the DM halo properties are reasonably well recovered by the JAM models. There is, however, a strong correlation between how well we recover the mass and the radial distribution of the DM and the number of GCs in the galaxy: the constraints get exponentially worse with fewer GCs, and at least 150 GCs are needed in order to guarantee that the JAM model will perform well. We find that while the data quality (uncertainty on the radial velocities) can be important, the number of GCs is the dominant factor in terms of the accuracy and precision of the measurements. This work shows promising results for these models to be used in extragalactic systems with a sample of more than 150 GCs.

description: Abridged: Observed abundances of extremely metal-poor (EMP) stars in the Halo hold clues for the understanding of the ancient universe. Interpreting these clues requires theoretical stellar models at the low-Z regime. We provide the nucleosynthetic yields of intermediate-mass Z=$10^{-5}$ stars between 3 and 7.5 $M_{sun}$, and quantify the effects of the uncertain wind rates. We expect these yields can be eventually used to assess the contribution to the chemical inventory of the early universe, and to help interpret abundances of selected C-enhanced EMP stars. By comparing our models and other existing in the literature, we explore evolutionary and nucleosynthetic trends with wind prescriptions and with initial metallicity. We compare our results to observations of CEMP-s stars belonging to the Halo. The yields of intermediate-mass EMP stars reflect the effects of very deep second dredge-up (for the most massive models), superimposed with the combined signatures of hot-bottom burning and third dredge-up. We confirm the reported trend that models with initial metallicity Z$_{ini}$ <= 0.001 give positive yields of $^{12}C, ^{15}N, ^{16}O$, and $^{26}Mg$. The $^{20}Ne, ^{21}Ne$, and $^{24}Mg$ yields, which were reported to be negative at Z$_{ini}$ = 0.0001, become positive for Z=$10^{-5}$. The results using two different prescriptions for mass-loss rates differ widely in terms of the duration of the thermally-pulsing (Super) AGB phase, overall efficiency of the third dredge-up episode, and nucleosynthetic yields. The most efficient of the standard wind rates frequently used in the literature seems to favour agreement between our yield results and observational data. Regardless of the wind prescription, all our models become N-enhanced EMP stars.

description: A first-principles-derived scheme, that incorporates ferroelectric and antiferrodistortive degrees of freedom, is developed to study finite-temperature properties of PbZr1-xTixO3 solid solutions near its morphotropic phase boundary. The use of this numerical technique (i) resolves controversies about the monoclinic ground-state for some Ti compositions, (ii) leads to the discovery of an overlooked phase, and (iii) yields three multiphase points, that are each associated with four phases. Additional neutron diffraction measurements strongly support some of these predictions.

description: Soft skills are interpersonal skills and competence that help higher education graduates secure jobs and perform well in their personal and career development. It boosts individual confidence and enhances graduate employability. To this effect, the paper discusses soft skills development in higher education as a pathway to graduate productivity. The main thrust of the study is to climax the significance of soft skills in graduate employability. The study examines high-demand soft skills in the jobs market, including analytical, problem-solving, technical and communication skills. The study relies on secondary data including literature, journals, and textbooks to provide an expository analysis of the subject matter. The study highlights that traditional teaching methods prioritize technical knowledge over soft skills, hindering their development in tertiary education. The study submits that possessing soft skills increases employability and acts as a catalyst for personal and career development. The paper suggests that managers of tertiary educational institutions should integrate digital technology into the pedagogical content among others

Joint Management of Compute and Radio Resources in Mobile Edge Computing: a Market Equilibrium Approach

description: Edge computing has been recently introduced as a way to bring computational capabilities closer to end users of modern network-based services, in order to support existent and future delay-sensitive applications by effectively addressing the high propagation delay issue that affects cloud computing. However, the problem of efficiently and fairly manage the system resources presents particular challenges due to the limited capacity of both edge nodes and wireless access networks, as well as the heterogeneity of resources and services' requirements. To this end, we propose a techno-economic market where service providers act as buyers, securing both radio and computing resources for the execution of their associated end users' jobs, while being constrained by a budget limit. We design an allocation mechanism that employs convex programming in order to find the unique market equilibrium point that maximizes fairness, while making sure that all buyers receive their preferred resource bundle. Additionally, we derive theoretical properties that confirm how the market equilibrium approach strikes a balance between fairness and efficiency. We also propose alternative allocation mechanisms and give a comparison with the market-based mechanism. Finally, we conduct simulations in order to numerically analyze and compare the performance of the mechanisms and confirm the theoretical properties of the market model.
