description: Trans-Neptunian objects (TNO) represent the leftovers of the formation of the Solar System. Their physical properties provide constraints to the models of formation and evolution of the various dynamical classes of objects in the outer Solar System. Based on a sample of 19 classical TNOs we determine radiometric sizes, geometric albedos and beaming parameters. Our sample is composed of both dynamically hot and cold classicals. We study the correlations of diameter and albedo of these two subsamples with each other and with orbital parameters, spectral slopes and colors. We have done three-band photometric observations with Herschel/PACS and we use a consistent method for data reduction and aperture photometry of this sample to obtain monochromatic flux densities at 70.0, 100.0 and 160.0 μm. Additionally, we use Spitzer/MIPS flux densities at 23.68 and 71.42 μm when available, and we present new Spitzer flux densities of eight targets. We derive diameters and albedos with the near-Earth asteroid thermal model (NEATM). As auxiliary data we use reexamined absolute visual magnitudes from the literature and data bases, part of which have been obtained by ground based programs in support of our Herschel key program. We have determined for the first time radiometric sizes and albedos of eight classical TNOs, and refined previous size and albedo estimates or limits of 11 other classicals. The new size estimates of 2002 MS4 and 120347 Salacia indicate that they are among the 10 largest TNOs known. Our new results confirm the recent findings that there are very diverse albedos among the classical TNOs and that cold classicals possess a high average albedo (0.17 +/- 0.04). Diameters of classical TNOs strongly correlate with orbital inclination in our sample. We also determine the bulk densities of six binary TNOs.

description: Diese Veröffentlichung behandelt eine neuartige Konstantstromladertopologie für Hochspannungskondensatoren, welche sich besonders für den mobilen Einsatz bei variablen Eingangsspannungen mit hohen Ausgangsleistungen eignet. Als besondere Anforderung ergibt sich hierbei die hohe geforderte Effizienz durch die begrenzt verfügbare Energiemenge der Batterieversorgung in Verbindung mit den benötigten sehr hohen Eingangsströmen. Weiterhin erfordert der mobile Einsatz eine Topologie, die möglichst wenig Volumen einnimmt und ein niedriges Gewicht bietet. Ein 2 kW Prototyp mit 50 kV Ausgangsspannung wurde entwickelt und in Betrieb genommen, der mit einer Eingangsspannung zwischen 20 und 50 V versorgt wird, wodurch sich Eingangsströme über 100 A ergeben. Zur Reduktion der Verlustleistung wurde eine neues Snubberkonzept entwickelt, das Überspannungen an den Halbleiterschaltern eliminiert, indem eine schnellere Kommutierung erfolgt, wodurch auch Schalter mit niedrigeren Sperrspannungen und daraus folgend niedrigerem Durchgangswiderstand eingesetzt werden können.

Subjects: subject: power distribution networks of medium voltage

subject: 620

description: Rapid fault determination of single-phase earth fault (SPEF) and SPEF location on the line are extremely important for the speedy elimination of damage and restoring normal operation of the power supply. Effective methods of SPEF determination on the cable lines under voltage do not still exist in medium voltage networks. The electrical values of the transition process that occurs during the breakdown of the insulation can be used for solving the problem of determining the place of single-phase including self-eliminating faults. The best method to study the electromagnetic transients at SPEF in medium-voltage networks and to identify the information parameters, which can be used for distant SPEF determination, is a combination of analytical methods on the basis of simplified models of the electrical networks and the method of computer simulation.

description: Ziel der Arbeit ist es ein Verfahren zur Spannungsreglung auf Basis eines Spannungsbeobachters im Niederspannungsnetz zu entwickeln und zu implementieren. Die Anforderungen an das Verfahren resultieren aus unterschiedlichen Schnittpunkten. Für das Ortsnetz gilt die Einhaltung des Spannungsbandes (nach DIN EN 50160), von ± 10 % bezogen auf die Nennspannung, an allen Stellen im Netz. Ebenso stellt die regelnde Einheit in der Ortsnetzstation Anforderungen an die Sollwertvorgabe. Hier werden elektromechanische und rein elektrische Ausführungen unterschieden. Ausgehend hiervon werden zwei unterschiedliche Verfahren Implementiert. Die dritte Komponente stellt das Ergebnis des Beobachters dar. Hier müssen je nach Topologie bis zu 12 Maschen im Spannungsband geführt werden. Weiter können Zustände auftreten, in welchen der beobachtete Wert nicht korrekt vorliegt, auch hier ist ein reibungsloser Betrieb zu gewährleisten.

description: As compressed air energy storage (CAES) is a promising energy storage technology that has already proven its reliability in commercial operation some basic thermodynamic information on this process are elaborated in this paper. It shows a comparison of the thermodynamic process cycles of the CAES plants in Huntorf and McIntosh that has been modeled in EES (Engineering Equation Solver). Detailed T-s-Diagrams are given to show the differences of reversible and irreversible thermodynamic modeling of CAES. It is demonstrated that irreversibility assumption leads to an over estimation of the plant efficiency and therefore newer CAES concepts (like adiabatic CAES) should not be approximated with reversibility assumptions to avoid misleading statements.

description: We perform laser spectroscopy of Yb+ ions on the 4f14 6s 2S_{1/2} - 4f13 5d 6s 3D[3/2]_{1/2} transition at 297 nm. The frequency measurements for 170Yb+, 172Yb+, 174Yb+, and 176Yb+ reveal the specific mass shift as well as the field shifts. In addition, we demonstrate laser cooling of Yb+ ions using this transition and show that light at 297 nm can be used as the second step in the photoionization of neutral Yb atoms.

description: Protections based by higher harmonics absolute measurements the zero sequence currents of the protected object connections against single-phase earth faults in resonant grounded cable networks of medium voltage industrial and urban energy supply systems have been widely applied in Russia since the late 60s of the 20th century. However, some operational problems connected with sufficient selectivity and sensitivity of these protection devices appeared with time. Sensitivity and selectivity of this protection are considerably determined by the instability degree of the higher harmonics total level in single-phase earth fault current of the protected network. Well-known Russian expert Kiskachi V.M. gave approximate estimate of the higher harmonics instability degree at the end of the 60s. Nowadays due to load changes in the main substations load in resonant grounded cable networks of medium voltage higher harmonics fluctuations in single-phase to earth fault current. The simulation models of this networks application and the accumulated experimental data about real networks allow to specify the existing estimates of higher harmonics instability in single-phase to earth fault current and their applicability conditions.

description: This paper discusses the derivation of an effective shell-model hamiltonian starting from a realistic nucleon-nucleon potential by way of perturbation theory. More precisely, we present the state of the art of this approach when the starting point is the perturbative expansion of the Q-box vertex function. Questions arising from diagrammatics, intermediate-states and order-by-order convergences, and their dependence on the chosen nucleon-nucleon potential, are discussed in detail, and the results of numerical applications for the p-shell model space starting from chiral next-to-next-to-next-to-leading order potentials are shown. Moreover, an alternative graphical method to derive the effective hamiltonian, based on the Z-box vertex function recently introduced by Suzuki et al., is applied to the case of a non-degenerate (0+2) hbaromega model space. Finally, our shell-model results are compared with the exact ones obtained from no-core shell-model calculations.

description: Today’s power grids must utilize more energy than they were originally planned for. Hence, they are slowly reaching their stability limits and that causes an increased risk of blackouts in electrical networks. To avoid such critical situations in the control room the system dynamic state must be assessed as quickly as possible and its personnel have to react to it early enough. This kind of evaluation could be done by the so-called Dynamic Security Assessment system which is able to assess the dynamic state of the electrical network online. This paper presents completely automatic methods of the dynamic security assessment system integration into a power grid, functionality testing of the Over Excitation Limiter (OXL) - which is implemented in the Automatic Voltage Regulator (AVR), and the electrical grid plausibility check.

description: As local renewable energy based generation units are being deployed worldwide, distribution grids are facing integration challenges. Here, microgrids provide a solution, by allowing intentional islanding and connection to the public distribution grid depending upon its current state. Microgrids may consist of loads, generation units and storages which can be operated as a single controllable entity. This paper investigates two control approaches for cost-efficient operation of grid-connected microgrids: optimization- and rule-based control. For optimizationbased control, a model predictive control algorithm with mixed integer linear programming formulation is used. A case study for a microgrid in an office building consisting of distributed generation units and different storage units is presented to assess the performance of the two control approaches. The simulation results show the effectiveness of the optimization-based approach and a potential for lower microgrid operating costs compared to the rule-based approach.
Accelerating consensus on co-evolving networks: the effect of committed individuals

description: Social networks are not static but rather constantly evolve in time. One of the elements thought to drive the evolution of social network structure is homophily - the need for individuals to connect with others who are similar to them. In this paper, we study how the spread of a new opinion, idea, or behavior on such a homophily-driven social network is affected by the changing network structure. In particular, using simulations, we study a variant of the Axelrod model on a network with a homophilic rewiring rule imposed. First, we find that the presence of homophilic rewiring within the network, in general, impedes the reaching of consensus in opinion, as the time to reach consensus diverges exponentially with network size $N$. We then investigate whether the introduction of committed individuals who are rigid in their opinion on a particular issue, can speed up the convergence to consensus on that issue. We demonstrate that as committed agents are added, beyond a critical value of the committed fraction, the consensus time growth becomes logarithmic in network size $N$. Furthermore, we show that slight changes in the interaction rule can produce strikingly different results in the scaling behavior of $T_c$. However, the benefit gained by introducing committed agents is qualitatively preserved across all the interaction rules we consider.

description: Die Energieversorgung in Deutschland befindet sich seit geraumer Zeit im Umbruch. Spätestens jedoch mit dem Energiekonzept der Bundesregierung von September 2010 wurde ein grundlegender Umbau eingeleitet. Ziel ist unter anderem eine deutliche Steigerung des Anteils erneuerbarer Energien am transportierten Strom. Da der Strom aus erneuerbaren Energien zu großen Teilen weit entfernt von den Verbrauchszentren produziert wird, stellt der Ausbau der Stromnetze eine wesentliche Voraussetzung zur Realisierung dieses Ziels dar. Dieser erscheint jedoch aus heutiger Sicht in dem benötigten Ausmaß nicht realistisch. Daher werden Alternativen zum klassischen Netzausbau gesucht, welche sowohl die Spannungshaltung als auch die Einhaltung der einschlägigen Normen gewährleisten. Eine mögliche Alternative stellt die Entwicklung von innovativen Netzbetriebsstrategien dar. Diese dienen der Nutzung von Reserven der vorhandenen Netzinfrastruktur durch einen unkonventionellen Betrieb des Energiesystems. Die Planung des Einsatzes dieses unkonventionellen Netzbetriebs erfolgt durch die Vorausberechnung mittels herkömmlicher Netzmodelle. Die Funktion und Wirksamkeit des Einsatzes hängt demnach von der Eignung der Netzmodelle zur Planung dieser Strategien ab. Das Paper beschreibt die Eignungsfeststellung herkömmlicher Netzmodelle zur Auslegung und Planung der Netzbetriebsstrategie des 'low-impact operation mode'. Die verwendeten Netzmodelle werden anhand einer experimentellen Validierung im Labormaßstab geprüft und bewertet.

description: The current challenges facing the aerospace domain require unconventional solutions, which could be sought in new configurations of future aircraft and spacecraft. The choice of optimal concepts requires the consideration of a significant amount of competing engineering solutions and takes place under conditions of uncertainty. Such a problem can be addressed by enhancing existing methods for analysis and synthesis solutions, such as the Advanced Morphological Approach (AMA). It uses morphological analysis to provide a more exhaustive overview of possible problem solutions, relies on expert evaluations of alternative technological options and applies clustering to the solution space. Although an intuitive method for structured concept generation, the AMA exposes the need for more robust problem structuring, improved objectivity of options evaluation and accounting for uncertainties. The current article suggests ways to overcome these challenges and their possible integration in the process. In particular, the integration of fuzzy sets is proposed to model uncertainties during the evaluation of technological options by the experts. The Fuzzy Analytical Hierarchy Process is adapted for integration into the AMA and for the conceptual design of aerospace vehicles.

description: We report the experimental demonstration of the superluminal propagation of multi-spatial-mode images via four-wave mixing in hot atomic vapor, in which all spatial sub-regions propagate with negative group velocities. We investigate the spatial mode properties and temporal reshaping of the fast light images, and show large relative pulse peak advancements of up to 64% of the input pulse width. The degree of temporal reshaping is quantified and increases as the relative pulse peak advancement increases. When optimized for image quality or pulse advancement, negative group velocities of up to $v_{g}=-\frac{c}{880}$ and $v_{g}=-\frac{c}{2180}$, respectively, are demonstrated when integrating temporally over the entire image. The present results are applicable to temporal cloaking devices that require strong manipulation of the dispersion relation, where one can envision temporally cloaking various spatial regions of an image for different durations. Additionally, the modes involved in a four-wave mixing process similar to the present experiment have been shown to exhibit quantum correlations and entanglement. The results presented here provide insight into how to tailor experimental tests of the behavior of these quantum correlations and entanglement in the superluminal regime.

description: An energy economy with high share of renewable but volatile energy sources is dependent on storage strategies in order to ensure sufficient energy delivery in periods of e.g. low wind and/or low solar radiation. Hydrogen as environmental friendly energy carrier is thought to be an appropriate solution for large scale energy storage. In 2011 the NOW (national organisation for hydrogen in Germany) calculated the demand for hydrogen energy systems as positive (0.8 GW to 5.25 GW) and negative supply for varying power demand (0.68 to 4.3 GW) for the German energy economy in 2025. Due to its dynamic behaviour on load changes polymer electrolyte membrane fuel cells (PEMFC) as well as water electrolyser systems (PEMEL) can play a significant role for large scale hydrogen based storage systems. In this work a novel design concept for modular fuel cell and electrolyser stacks is presented with single cells in pockets surrounded by a hydraulic medium. This hydraulic medium introduces necessary compression forces on the membrane electrode assembly (MEA) of each cell within a stack. Furthermore, ideal stack cooling is achieved by this medium. Due to its modularity and scalability the modular stack design with hydraulic compression meets the requirements for large PEMFC as well as PEMEL units. Small scale prototypes presented in this work illustrate the potential of this design concept.

description: We aimed to study the chemistry of the circumnuclear molecular gas of NGC1068, and to compare it with those of the starburst galaxies M82 and NGC253. Using the IRAM-30m telescope, we observed the inner 2 kpc of NGC1068 between 86.2 GHz and 115.6 GHz. We identified 35 spectral features, corresponding to 24 different molecular species. Among them, HC3N, SO, N2H+, CH3CN, NS, 13CN, and HN13C are detected for the first time in NGC1068. Assuming local thermodynamic equilibrium (LTE), we calculated the column densities of the detected molecules, as well as the upper limits to the column densities of some undetected species. The comparison among the chemistries of NGC1068, M82, and NGC253, suggests that, apart from X-rays, shocks also determine the chemistry of NGC1068. We propose the column density ratio between CH3CCH and HC3N as a prime indicator of the imprints of starburst and AGN environments in the circumnuclear interstellar medium. This ratio is, at least, 64 times larger in M82 than in NGC1068, and, at least, 4 times larger in NGC253 than in NGC1068. Finally, we used the UCL_CHEM and UCL_PDR chemical codes to constrain the origin of the species, as well as to test the influence of UV radiation fields and cosmic rays on the observed abundances.

description: This research paper enquires the Financial Response approach linked to fiscal cost orientation model for disaster crisis management. The analysis presents an overview of the approach implemented by Fiscal Policy in Albania while facing the natural disasters. Based on the international reports findings (World Bank and IMF) and DesInventar database, Albania is categorized as one of the countries with the highest risk in Europe. Facing these phenomena continuously, followed by November 26th earthquake as well as the Covid-19 pandemic, a comparative analysis of the country's "Financial Response" with the most successful models proposed by International Financial Institutions has been carried out. The use of the Reserve Fund and Virement model only, is not considered appropriate to be followed for countries with high disaster risk. Key words: Financial response, cost orientation, risk management.

description: Herein we report on the preparation of a bioactive glass (BAG)-based photocurable resin for the additive manufacturing of BAG scaffolds with high filler loadings. The preparation of glass/ceramics resins for stereolithography with high filler loading is always a challenge, especially for fillers with a high refractive index variance. Various photocurable resin compositions with and without bioactive glass fillers have been investigated to see the influence of bioactive glass on physical properties of the resin and resulting green body. The effect of concentration of monomers, reactive diluent, light absorber (Sudan orange G dye), photoinitiator (PI), non-reactive diluent, and fillers (BAG) on rheology and photocuring behavior of the resin and tomography of the resulting 3D structures have been investigated. The BAG contents affect the rheology of resin and influence the rate of the polymerization reaction. The resin compositions with 55–60% BAG, 10% PEG-200 (diluent), 1% of PI and 0.015% of the dye were found to be suitable compositions for the stereolithographic fabrication. A higher percentage of PI caused over-curing, while a higher amount of dye decreased the cure depth of the resin. The micro-computed tomography (µ-CT) and scanning electron microscopic (SEM) images of the resulting green bodies display a relatively dense glass scaffold without any visible cracks and good interlayer connection and surface finishing. These properties play an important role in the mechanical behavior of 3D scaffolds. This study will be helpful to prepare high density glass/ceramic slurries and optimize their printing properties.

description: An der Fachhochschule Bielefeld wird im Rahmen des Forschungsprojektes „Optimierung von Brennstoffzellenheizgeräten als Komponente einer zukünftigen Gebäudeenergieversorgung in Smart Cities“ ein PEMBrennstoffzellensystem mit integriertem BHKW-Simulator im skalierten Maßstab betrieben. Gefördert wurde der Langzeit- Teststand für PEM-BZ von dem Unternehmen „inhouse engineering GmbH“ aus Mitteln des Landes NRW (Programm FH Extra). Nach erfolgreicher Inbetriebnahme des Systems, ersten Probemessungen und dem Erstellen von Referenzkennlinien bei unterschiedlichen Betriebstemperaturen ist ein weiterer wichtiger Schritt innerhalb des Projektes die Modellbildung. Das Modell wird mit Hilfe von geeigneten Messungen verifiziert. Langfristig ist es das Ziel, eine Optimierung der Betriebsführung von Brennstoffzellenheizgeräten in Kombination mit unterschiedlichen Peripheriekomponenten wie z.B. einem thermischen Speicher und elektrischen Verbrauchern zu erreichen.

description: Modal quantum theory (MQT) is a "toy model" of quantum theory in which amplitudes are elements of a general field. The theory predicts, not the probabilities of a measurement result, but only whether or not a result is possible. In this paper we review MQT and extend it to include mixed states, generalized measurements and open system dynamics. Even though MQT does not have density operators, superoperators or any concept of "positivity", we can nevertheless establish a precise analogue to the usual representation theorem for CP maps. We also embed MQT in a larger class of modal theories. We show that the possibility assignments for separate measurements on a bipartite system in MQT are always weakly consistent with some probability assignment that respects the no-signalling principle.

description: Bridging the gap between theoretical modeling and practical implementation is essential in fault detection, classification, and location methods for modern distribution grids. Currently distribution grids are characterized by dispersed infeed and distributed power generation that render conventional protection settings more challenging, and, hence, new methods must be investigated to resolve these issues. In this paper, a novel framework capable of detecting and classifying faults in power distribution grids is presented. The proposed algorithm formulates a unique fault classification technique based on measurement samples of three-phase voltage and currents after the occurrence of a fault event in power distribution grid. Thereby, negative sequence components of three-phase voltage and current quantities are used for online fault detection that triggers a fault classification method based on a support vector machine. In order to simulate fault scenarios, a model of a reference distribution grid incorporating distributed generation is developed, simulated, and analyzed under fault conditions. For the final evaluation, the designed protection scheme is implemented on a Programmable Logic Controller connected to the model running on a real-time simulator hardware that provides voltage and current measurements. Thus experimental results are provided to demonstrate and prove the contribution of the algorithm in its ability to correctly identify and classify faults in modern distribution grids.
