Slides presented at webinar: GPS Spoofing Detection for PMUs Using a Hybrid Network
In the future Smart Grid, Phasor Measurement Units (PMUs) will monitor the power grid state in real-time by synchronizing measurements across the network using GPS. However, because civilian GPS is unencrypted, PMUs are susceptible to spoofing. This webinar presents a spoofing detection algorithm using a wide-area, hybrid communication architecture: Each PMU securely transmits conditioned signal fragments containing the military P(Y) signal, which serves as an encrypted signature in the background of all authentic GPS signals. This signature is then verified amongst several, distant receivers, strategically picked with a subset selection algorithm. The algorithm has been demonstrated to successfully evaluates the authenticity of a widely dispersed receiver network, using real- world data recorded during a government-sponsored, live-sky spoofing event.

Slides presented at webinar: Coordinating of Energy Storage and Flexible Demand Resources
Energy storage is needed to help the power grid of the future in balancing the highs and lows caused by intermittent renewables such as solar and wind. Flexible demand ? such as air conditioning ? can provide the same service as batteries by manipulating their demand around a nominal baseline so that the increase and decrease of demand appears like charging and discharging of a battery. The advantage of these ?virtual batteries? over real batteries is their low cost, since only a change in software is needed. A challenge in the effective use of both real and virtual batteries is coordination: a large number of them need to be coordinated so that together they supply what the grid needs. At the same time, the Quality of Service (QoS) of each consumer ? on whose premises a flexible load or a battery resides - must be maintained within strict, pre-negotiated, bounds. In this webinar, we will describe methods for coordinating a large number of energy storage and flexible demand resources, and discuss the pros and cons of these methods.

description: We show that the fractional statistics of quasiparticles in dimerized graphene, in recent proposals for charge and statistics fractionalization, can have two realizations depending whether elementary objects can be considered as point-like or extended objects. Therefore, there are two phases of proposed excitations and we give their topological descriptions with their respective statistics. We propose that a natural setting for fractionalization are certain systems with excitonic instabilities and demonstrate this by an example of graphene bilayer.

Slides presented at  Session 2 : Grid 4.0: Cyber-Physical Systems Enable a Modern Grid
For nearly a century the driving force for the U.S. electric grid was growth while the technologies and business model changed incrementally. The OPEC oil embargo in 1973 marked an inflection point after which its foundations began to erode. New electronics, information, communications, and energy technologies led to rapid growth of distributed energy resources (energy production, storage, monitoring, management). An increasingly decentralized and complex "Grid Edge" poses profound challenges for planning, operations, and management of the legacy electric grid. The fourth industrial revolution (cyber-physical systems operating via the Internet of Things) brings new ways of dealing with the challenges and maximizing the benefits of a new electric grid model.

Slides presented at webinar: Digital Twin and its Application to Power Grid Online Analysis
A new fast online analysis system development project, sponsored by the State Grid of China, was started in 2006. The primary goal of the project was set to reduce the online analysis overall round-trip time, from data acquisition to complete the analysis, from the current proximate 10 minutes to less than 60 seconds. The project development work has been completed at the end of 2018. A pilot new online analysis system has been deployed and running in a provincial dispatching center in China. The preliminary testing data indicates that the new online analysis system can achieve sub-second response speed. Digital Twin (DT) has been in the Gartner's Top 10 Strategic Technology Trends list every year since 2017. In the project development, an Online Analysis Digital Twin (OADT) has been implemented. In this presentation, the DT concept will be introduced in the context of application to power grid online analysis. A high-level overview of the project and some of the preliminary performance testing results will be presented. The overview will include the project high-level solution architecture, the DT concept used in framing the solution architecture, the OADT implementation to support the solution architecture realization, and the pilot online analysis system implementation details.

Hin und zurück by Paul Hindemith : a production thesis
Creators: name: Riley, Douglas V.
Publisher: name: University of British Columbia
Year: 2010

description: Hin und Zurtick, a short, one-act opera written in 1927 by Paul Hindemith, was produced, designed, conducted and staged by Douglas V. Riley, in partial fulfillment of the requirements for a Master of Music degree in the Department of Music of the University of British Columbia. This opera was produced on a budget of $232.07 and was performed by a student cast on November 29 and 30, 19 74 in the Old Auditorium Theatre which seats approximately 550 people. The following is a detailed record of that production with the stage director's analysis and interpretation of the musical score. This record is divided into seven chapters and a final section containing a bibliography and production appendices. The first chapter deals with the reasons for choosing the opera itself, taking into account the restrictions of an opera workshop: that is, a limited number of singers, young voices, inexperienced actors and the necessary simplicity of the design and production. This is followed by a short historical look at the composer and at the opera itself in Chapter Two. The third chapter contains specific notes on the different approaches to the conceptualization of the production and a discussion of the origin and basis of the final directorial concept. It also discusses intellectual and other analytic considerations dealing with dramaturgy and the projected production and directorial problems. The fourth chapter covers the specific organization of the production and the detailed final realization of the staging. Cast selection and its related problems are then considered. This chapter also includes a scene-by-scene analysis which covers purpose, actions, musically-denoted actions, dominant emotions and the particular difficulties encountered therein. This chapter concludes with specific references to aspects of acting by young performers. Chapter Five deals with the conductor's personal preparation as a basis for co-ordinating the work both in rehearsal and during performances. The chapter then deals with all other musical considerations and their particular relations to both the performers and the audience of Hin und Zuriick. The straightforward approach to the planning and construction of the scenery is discussed in Chapter Six which also describes the different methods of stage lighting. It concludes with an assessment of the final outcome. Chapter Seven is a short appraisal of the entire production from different points of view, including a discussion of the opera as it relates to the director/producer. The final section consists of a bibliography and various appendices, from a scene breakdown to the photo-copied reproduction of the score.

Floating wind turbine

description: This document is related to the results of Work Package 5 of the FLOATECH project (Optimization of floating wind turbines using innovative control techniques and fully coupled open-source engineering tool). The main goal of WP 5 is the estimation of the impact of the newly developed technologies on the economic performance of floating wind turbines. Specifically, WP5 has investigated the effects on the overall component costs due to the introduction of two new control strategies: Active Wave Control (AWC), related to the feed forward control methodology developed in WP 3 of FLOATECH project, and Active Wake Mixing (AWM), related to the wake mixing control strategy developed in WP 4. Two different tasks are devoted to the new control models, Task 5.1, dedicated to the study of AWC, and Task 5.2 dedicated to AWM. In order to explore the economic effects of the implementation of the new controls, a cost model parametrized on the main geometrical and performance data of the FOWT, is simultaneously under development in Task 5.3. This report is specifically related to the economic assessment of the AWC control implementation. This study exploits the results of simulations performed using QBlade, in order to estimate the loads on the main FOWT components. The methodology used to estimate the possible improvements due to the newly introduced control technology is based on a hybrid approach: on the one hand, some cost contributions will be estimated using expressions based on statistical regression, typically derived from literature, while, on the other hand, the costs of the FOWT components mainly affected by the control variation will be estimated using a simplified preliminary design calculations, in order to evaluate possible changes in design parameters due to the predicted load variations. In LCOE estimation, possible changes in the annual energy production are also accounted for. Results are presented in terms of variation of the LCOE between a reference case and a modified design including the AWC control technology, developed at the Ecole Central Nantes with an innovative control system designed by TUDelft.

Slides presented at webinar: Power System Dynamic State Estimation using Synchrophasor Measurements
With the increasing penetration of intermittent renewable energy, responsive loads, and microgrids, the power system has been subject to different types of dynamics. Consequently, the static state estimation (SSE) used in today?s energy management systems may be unable to capture these dynamics in an operational environment. As a result, new monitoring tools need to be developed, such as dynamic state estimation (DSE). The capability of DSE to accurately capture rapid dynamic changes in system states plays an important role in power system control and protection. Thanks to the widespread deployment of phasor measurement units, the development of a fast and robust DSE becomes possible. This webinar will present a comprehensive view of the DSE, in terms of its motivations, concepts, implementation and utilization. The similarities and differences between DSE and other existing estimation methods will be clarified as well.

description: We investigate the nonequilbrium dynamics of entanglement entropy and out-of-time-order correlator (OTOC) of noninteracting fermions at half-filling starting from a product state to distinguish the delocalized, multifractal (in the limit of nearest neighbor hopping), localized and mixed phases hosted by the quasiperiodic Aubry-André-Harper (AAH) model in the presence of long-range hopping. For sufficiently long-range hopping strength a secondary logarithmic behavior in the entanglement entropy is found in the mixed phases whereas the primary behavior is a power-law the exponent of which is different in different phases. The saturation value of entanglement entropy in the delocalized, multifractal and mixed phases depends linearly on system size whereas in the localized phase (in the short-range regime) it is independent of system size. The early-time growth of OTOC shows very different power-law behaviors in the presence of nearest neighbor hopping and long-range hopping. The late time decay of OTOC leads to noticeably different power-law exponents in different phases. The spatial profile of OTOC and its system-size dependence also provide distinct features to distinguish phases. In the mixed phases the spatial profile of OTOC shows two different dependences on space for small and large distances respectively. Interestingly the spatial profile contains large fluctuations at the special locations related to the quasiperiodicity parameter in the presence of multifractal states.

description: Unternehmenskulturen sind Kulturen, in denen sich über eine Zeit gemeinsamen Arbeitens Kommunikationsstrukturen ausbilden, die den Einzelnen mit den anderen verbinden. Es entsteht so in der Regel ein kohärentes Gewebe, das Mitarbeitern Orientierung gibt. Dies wird dann besonders bedeutend, wenn vor dem Hintergrund der zunehmenden "Stückhaftigkeit unserer Welt" (Clifford Geertz) Diskussionen über grundlegende gemeinsame Vorstellungen, gemeinsame Gefühle und gemeinsame Werte auch in der Arbeitswelt nicht immer einfach zu lösen sind. Innerhalb von Unternehmenskulturen bilden in der Regel narratologisch aufgebaute Firmengeschichten einen wichtigen Faktor, wenn es um die Herstellung von Identität im Unternehmen geht. Schlagwortartig werden solche Konzepte auf Internetseiten präsentiert und als Leitbegriffe verwendet, um das firmeneigene Narrativ plakativ nach außen zu kommunizieren. Begriffe wie Innovation, Tradition und Zukunftsorientiertheit sind dabei häufig verwendete Vokabeln. Sie sind abstrakte und positiv besetzte Bezugsgrößen eines ökonomischen Diskurses, der gerade von KMUs erwartet, den Betrieb so aufzustellen, dass er zeitgemäß und im Bewusstsein seiner eigenen Geschichte solide auch Kommendes überstehen mag. Von diesem Geflecht ökonomischer Anforderungen sind auch die Erzählungen über ein Unternehmen geprägt. Davon kann die Verwendung derartiger Vokabeln innerhalb von Unternehmen unterschieden werden. Somit wird angenommen, dass es eine Differenz zwischen Signifikaten werbender Internetdarstellungen und der Signifikantenlogik wirtschaftlicher Rationalitätsparadigmen gibt und die Frage nach der Unternehmenskultur in Unternehmen nicht auch die Fragen nach den eigenen Narrativen in Unternehmen offenlegt. Welche Rolle die Kommunikation in der Struktur der Organisation kleinerer und mittlerer Unternehmen spielt, die bestrebt sind, sich zwischen Traditionalität, Zukunftsorientiertheit und Marktzwängen zu positionieren, soll im Folgenden näher erörtert werden. Dabei sollen besonders Unternehmen in den Blick genommen werden, deren Organisationsstruktur sich - vor allem innerhalb ökonomischer Handlungskontexte - verändert hat. Wenn nämlich beispielsweise Unternehmensstrukturen (z.B. durch Fusion und Umstrukturierungen) dynamisiert und rationalisiert wurden, wird unter Umständen die Vergangenheit aus der Perspektive der Gegenwart beleuchtet und das Narrativ überdacht, weil solche Umstrukturierungen von den Mitarbeitern als Traditions- und Vertrauensbruch erlebt werden könnten. Genau an diesen Bruchstellen bekommen tradierte und neu formulierte Unternehmensnarrative eine erhebliche Bedeutung. Aus kultur- und kommunikationswissenschaftlicher Perspektive soll in diesem Beitrag das Wechselverhältnis zwischen organisatorischen, ökonomischen und kommunikativen Prozessen in Unternehmen behandelt werden, die ihre Betriebsstruktur und Leitkultur verändert haben.

Applying this model to Na4Ir3O8, we propose that the high temperature state may be described by a spinon Fermi surface, which forms a paired state with line nodes below 20 K. The possible mixed spin singlet and spin triplet pairing states are discussed according to the lattice symmetry which breaks inversion.

subject: FOS: Physical sciences

description: We study non-linear structure formation in high-resolution simulations of Early Dark Energy (EDE) cosmologies and compare their evolution with the standard LCDM model. Extensions of the spherical top-hat collapse model predict that the virial overdensity and linear threshold density for collapse should be modified in EDE model, yielding significant modifications in the expected halo mass function. Here we present numerical simulations that directly test these expectations. Interestingly, we find that the Sheth & Tormen formalism for estimating the abundance of dark matter halos continues to work very well in its standard form for the Early Dark Energy cosmologies, contrary to analytic predictions. The residuals are even slightly smaller than for LCDM. We also study the virial relationship between mass and dark matter velocity dispersion in different dark energy cosmologies, finding excellent agreement with the normalization for Lambda as calibrated by Evrard et al.(2008). The earlier growth of structure in EDE models relative to LCDM produces large differences in the mass functions at high redshift. This could be measured directly by counting groups as a function of the line-of-sight velocity dispersion, skirting the ambiguous problem of assigning a mass to the halo. Using dark matter substructures as a proxy for member galaxies, we demonstrate that even with 3-5 members sufficiently accurate measurements of the halo velocity dispersion function are possible. Finally, we determine the concentration-mass relationship for our EDE cosmologies. Consistent with the earlier formation time, the EDE halos show higher concentrations at a given halo mass. We find that the magnitude of the difference in concentration is well described by the prescription of Eke et al.(2001) for estimating halo concentrations.

Mono- und polyisotopische Lesarten

description: Peter Klimczak wiederum setzt sich mit Ir reiniu wîp, ir werden man (L. 66,21) mit einer der anspruchsvollsten Dichtungen Walther von der Vogelweides auseinander. Fast ein Jahrhundert lang wurde bezweifelt, ob es sich überhaupt um ein zusammenhängendes Lied handelt und bis jetzt besteht bezüglich der genauen Strophenfolge ein (Rest-)Dissens. Dieser resultiert aus der unterschiedlichen Lesarten des Liedes. Das auf Algirdas J. Greimas und François Rastier zurückgehende Isotopienmodell erlaubt die Differenzierung einer traditionellen, monoisotopischen, von einer progressiven, polyisotopischen, Lesart. Mit letzterer lassen sich entscheidende argumentative Brüche innerhalb und zwischen den Strophen auflösen und das Lied als enigmatischer Metatext über Literatur und Literaturinterpretation lesen. Aus einer solchen Perspektive heraus lässt sich dann auch eine bestimmte Strophenfolge klar präferieren.

Slides presented at  Session 1 : Grid 4.0: Cyber-Physical Systems Enable a Modern Grid
For nearly a century the driving force for the U.S. electric grid was growth while the technologies and business model changed incrementally. The OPEC oil embargo in 1973 marked an inflection point after which its foundations began to erode. New electronics, information, communications, and energy technologies led to rapid growth of distributed energy resources (energy production, storage, monitoring, management). An increasingly decentralized and complex "Grid Edge" poses profound challenges for planning, operations, and management of the legacy electric grid. The fourth industrial revolution (cyber-physical systems operating via the Internet of Things) brings new ways of dealing with the challenges and maximizing the benefits of a new electric grid model.

Slides for Webinar: Predictive Analytics for Power Systems Decision Making

Slides presented at webinar: Predictive Analytics for Power Systems Decision Making
Increasing amounts of heterogeneous sensor data and information are becoming available in energy grids from sources such as smart meters, distributed generation, and smart home energy management systems. Being able to collect, curate, and create actionable information with these data will be crucial to power systems operations with the increasing penetrations of distributed energy resources. In this webinar, we will present NREL?s latest work on developing predictive analytics to facilitate the real-time decision making in power systems operations. In this work, a high-precision predictive state estimator is first developed which employs sparse measurement data to provide system-wide awareness in distribution systems, while traditional state estimation techniques have difficulty coping with the low-observability conditions often present on the distribution systems due to the paucity of sensor measurements. Based on the predicted system conditions, grid operators can proactively control all the flexible resources by employing coordinated optimization techniques. The developed technologies allow grid operators to manage power systems with lean reserve margins while maintaining and enhancing grid reliability with high penetrations of renewable energy resources.
Arbeitswelt als Semiosphäre

description: Semiotisch gesehen bietet die Arbeitswelt viele Perspektiven für die Semiotik. Dies nicht nur deshalb, weil in der zeitgenössischen Erwerbsarbeit die meisten Tätigkeiten zum überwiegenden Teil aus der Produktion, Rezeption und Ver-Ar-beitung zeichenhafter Äußerungen besteht, sondern auch, weil ein wachsender Teil des Outputs unserer Wirtschaftsprozesse ganz oder teilweise in der Produktion und Verarbeitung von Zeichen und Äußerungen besteht. Ich widme mich in diesem Beitrag allerdings dem ersten Aspekt und betrachte dabei in Anlehnung an Jurij Lotman die Arbeitswelt als (Teil der) Semiosphäre, die einen spezifischen Umgang mit Zeichen und Kommunikation pflegt, und versuche dabei zu zeigen, welche theoretischen Zugänge und Methoden der Semiotik dazu beitragen (oder beitragen könnten), die Semiosphäre der Arbeitswelt besser beschreiben und daraus auch gezielte Interventionen zur Verbesserung der Unternehmenskommunikation entwickeln zu können.

Sexualität und Rollenzuweisung der Frau im späten DDR-Fernsehen
Creators: name: Neumann, Andreas
Publisher: name: Schriften zur Kultur- und Mediensemiotik | Online
Year: 2018

description: Andreas Neumann macht in seinem Beitrag auf einen bisher von der Medien- aber auch Geschichtswissenschaft nur unzureichend beachteten Bereich der DDR-Fernsehforschung aufmerksam: Die Rolle der Frau in Partnerschaft und ihre Sexualität, sowie der Wandel der dementsprechenden Diskurse im Laufe der Zeit. Dabei wird der Grundannahme Michel Foucaults gefolgt, wonach es sich bei der Sexualität um einen besonders dichten Durchgangspunkt für Machtbeziehungen, nicht zuletzt zwischen Mann und Frau sowie Verwaltung und Bevölkerung, handelt. Anhand von drei, durchaus für die ganze Familie konzipierten, Fernsehserien - ABER VATI! (DDR 1974/1979), MÄRKISCHE CHRONIK (DDR 1983) und JOHANNA (DDR 1989) - analysiert Andreas Neumann die Darstellung von weiblichen Rollenbildern und der dazugehörigen Sexualität. Abschließend widmet sich der Beitrag auch den gesellschaftspolitischen Implikationen der aufgezeigten Darstellungen.

Arbeit als Simulakrum des Geldes

Year: 2018

description: Die Ökonomie insgesamt, der Leitdiskurs der Moderne, die Baudrillard als Produktionszeitalter im 19. Jahrhundert ansiedelt, tritt im postmodernen Simulationszeitalter des 20. Jahrhunderts in ihr ästhetisches Stadium ein. Hierin dient Arbeit nicht mehr der Produktion, sondern verkommt sinnentleert zum Alibi eines abstrakten "Anwesenheitszwangs", der seinerseits nur gewährleisten soll, dass jeder an seinem Platz bleibt. In diesem Artikel soll jedoch eine andere Gewährleistung verdeutlicht werden. Arbeit soll wie bei Baudrillard verstanden werden als Simulakrum, aber als Simulakrum des Geldes. Anstatt nur gesellschaftliche Strukturen zu reproduzieren, dient Arbeit dieser Sichtweise gemäß vor allem der Beglaubigung des Geldes.

Slides presented at The Outbreak of Smart Grid Cyber-Security: The Modern Campfire Story
Recent cyber-security incidents have caused severe power outages in distribution system operations, which have highlighted the importance and urgency of improving the resilience of the electric distribution systems. Unlike IT networks, vulnerability of Smart Grid (SG) infrastructure has a direct impact on the vulnerability of system assets and operational outage costs. SG infrastructure can be secure, but yet not safe. Recent trends in cyber-security solutions have a broader necessity, not only on communications security, but the resiliency to cyber-attacks. This tutorial is intended to provide cyber-security definitions and technical considerations of SG critical infrastructure.
Agenda:
1. Overview and Definitions
2. The Path from philosophy to science to corporeality
3. Cyber-physical perspective (Requirements and developments)
4. Where to go (resources, targets), and how to go (backgrounds, starting point)
5. Conclusions
Nicht-Ort Bates Motel

description: Denis Newiak lotet anhand des umfangreichen filmischen Bildreservoirs von "Psycho" - von Hitchcocks Klassiker über die Fortsetzungsfilme bis hin zur aktuellen Fernsehserie BATES MOTEL (USA 2013-2017) - die Möglichkeiten einer kinematographischen Ikonografie der Einsamkeit aus. Die Welt von "Psycho" gilt dabei vorwiegend durch ihre hochgradige Modernität als unerschöpflicher Bildspeicher, der sich vorwiegend aus den "Nicht-Orten" (Augé) und deren verdächtigen Räumen hinter den Medienoberflächen speist. Unter Zuhilfenahme der Erkenntnisse der Kunstwissenschaft zu Einsamkeitsbildern in Malerei und Fotografie unterbreitet der Autor damit Vorschläge, wie sich eine Ikonografie der Einsamkeit als Abdruck der Moderne als Zeitalter zunehmender Vereinsamung denken ließe. Dies, so der Autor, könnte die Voraussetzung für einen neuartigen methodischen Zugang zu Kunstformen der Moderne im Allgemeinen bilden.
