description: 3 Stufen Pulswechselrichter (3 Level Inverter) werden eingesetzt in der elektrischen Drehstromantriebstechnik, als Netzeinspeisewechselrichter z.B. in der Photovoltaik oder als Aktive Leistungs-Netzfilter. Neben den bislang üblichen hart schaltenden Ausführungen gibt es seit kurzem mit dem „Soft Switching Three Level Inverter (S3L Inverter)“ eine weich schaltende Version mit geringeren Schaltverlusten und damit höherer Effizienz. Zusätzlich zeigt der S3L Inverter aufgrund der weichen Schaltvorgänge auch Vorteile hinsichtlich der Elektromagnetischen Verträglichkeit, insbesondere in der als „Super Soft Switching Three Level Inverter (SS3L Inverter)“ bezeichneten Varianten.

description: The article discusses the portrayal of the author’s wife in Zhitie (Life Story), the most well-­known pre-­modern Russian autobiography written by the archpriest Avvakum (1621/2 – 1682). The main question addressed in the article is the credibility of this portrayal. Its main conclusion suggests that while searching for historical truth in autobiographical stories we should take into consideration that they were written not for us but for some other readers, and that this difference of addressees complicates our search.

description: The wine market is increasingly sensitive to sustainability issues, thus calling for the use of environment-friendly productive processes. What is the willingness of consumers to pay for such products? This work aims to investigate how consumers perceive the value of a “precision viticulture” with respect to Italian wine “Falanghina del Sannio” using a mix of hypothetical and real scenarios, that is, the hypothetical van Westendorp’s Price Sensitivity Meter (PSM) and real experimental auctions employing the Becker-deGroot-Marschak (BDM) mechanisms. The value of the attribute “precision viticulture” ranges between 19.86% and 24.51% (optimally 22.20%) of the total value of a hypothetical sustainable bottle of wine. In particular the attribute “precision viticulture” would maximize revenue if priced 2 Euros. A 1% increase in the price of the new wine associated with “precision viticulture” would lead to a 2.26% reduction in the quantity demanded. Finally, results suggest that the higher the value of a regular bottle of wine, the higher the consumer’s WTP for the “precision viticulture” attribute.

description: Bike positional configuration changes strongly affect cycling performance. While consensus has emerged on saddle height optimisation, there is none for the relationship between other bike positional variables and cycling performance. Accordingly, this systematic review examines the effect of all major positional variables on performance in cycling, assessing differences between cycling disciplines and sex where possible. The systematic review, conducted per PRISMA guidelines, searched databases including Embase, Web of Science, Medline, and CINAHL, screening 16,578 studies. Of these, 47 were fully analysed. Study quality assessment using the NIH tool revealed none rated “good”, 5 “fair” and 33 “poor”. The analysis involved 724 participants (90 female, 454 male, 180 sex unstated). Studies focused on trunk angle/upper body position, handlebar height, Q factor, foot position, saddle fore-aft/height, seat tube angle and crank length. Participant cycling disciplines were often unspecified and few papers address women cyclists specifically. Key findings were associated with changing saddle height, trunk angle and saddle fore-aft. For trunk angle, accounting for the biomechanical and physiological effects as well as aerodynamic changes is important. Saddle fore-aft affects the hip angle and trunk angle. There are no clear recommendations for crank length, handlebar height, Q factor or cleat position.

description: The Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory is a state-of-the-art imager with the potential to do unprecedented time-dependent multi-thermal analysis at every pixel on scales short compared to the radiative and conductive cooling times. Recent results, however, have identified missing spectral lines in the CHIANTI atomic physics data base, which is used to construct the instrument response functions. We have done differential emission measure analysis using simultaneous AIA and Hinode/EIS observations of six X-ray bright points. Our results not only support the conclusion that CHIANTI is incomplete near 131 angstroms, but more importantly, suggest that the peak temperature of the Fe VIII emissivity/response is likely to be closer to log T = 5.8 than to the current value of log T = 5.7. Using a revised emissivity/response calculation for Fe VIII, we find that the observed AIA 131-angstrom flux can be underestimated by about 1.25, which is smaller than previous comparisons.

description: Non-radioactive electron sources are of great interest in any application requiring the emission of electrons at atmospheric pressure, as they offer better control over emission parameters than radioactive electron sources and are not subject to legal restrictions. Recently, we published a simple electron source consisting only of a vacuum housing, a filament, and a single control grid. In this paper, we present improved control electronics that utilize this control grid in order to focus and defocus the electron beam, thus pulsing the electron emission at atmospheric pressure. This allows short emission pulses and excellent stability of the emitted electron current due to continuous control, both during pulsed and continuous operations. As an application example, this electron source is coupled to an ion mobility spectrometer. Here, the pulsed electron source allows experiments on gas phase ion chemistry (e.g., ion generation and recombination kinetics) and can even remove the need for a traditional ion shutter.
Two remarks on the reduction of Alperin's weight conjecture

description: The so-called inductive McKay condition on finite simple groups, due to Isaacs-Malle-Navarro (2007), has been recently reformulated by Späth. We show that this reformulation applies to the reduction theorem for Alperin's weight conjecture, due to Navarro-Tiep (2011). This also simplifies the checking of the inductive condition for Alperin's weight conjecture in the case of simple groups of Lie type with regard to the defining prime.
Effect of dot size on exciton binding energy and electron-hole recombination probability in CdSe quantum dots

description: Exciton binding energy and electron-hole recombination probability are presented as the two important metrics for investigating effect of dot size on electron-hole interaction in CdSe quantum dots. Direct computation of electron-hole recombination probability is challenging because it requires an accurate mathematical description of electron-hole wavefunction in the neighborhood of the electron-hole coalescence point. In this work, we address this challenge by solving the electron-hole Schrodinger equation using the electron-hole explicitly correlated Hartree-Fock (eh-XCHF) method. The calculations were performed for a series of CdSe clusters ranging from $\mathrm{Cd}_{20}\mathrm{Se}_{19}$ to $\mathrm{Cd}_{74608}\mathrm{Se}_{74837}$ that correspond to dot diameter range of 1-20 nm. The calculated exciton binding energies and electron-hole recombination probabilities were found to decrease with increasing dot size. Both of these quantities were found to scale as $D_\mathrm{dot}^{-n}$ with respect to the dot diameter D. One of the key insights from this study is that the electron-hole recombination probability decreases at a much faster rate than the exciton binding energy as a function of dot size. It was found that an increase in the dot size by a factor of 16.1, resulted in a decrease in the exciton binding energy and electron-hole recombination probability by a factor of 14.4 and $5.5\times10^{6}$, respectively.

description: Based on network analysis of hierarchical structural relations among Chinese characters, we develop an efficient learning strategy of Chinese characters. We regard a more efficient learning method if one learns the same number of useful Chinese characters in less effort or time. We construct a node-weighted network of Chinese characters, where character usage frequencies are used as node weights. Using this hierarchical node-weighted network, we propose a new learning method, the distributed node weight (DNW) strategy, which is based on a new measure of nodes' importance that takes into account both the weight of the nodes and the hierarchical structure of the network. Chinese character learning strategies, particularly their learning order, are analyzed as dynamical processes over the network. We compare the efficiency of three theoretical learning methods and two commonly used methods from mainstream Chinese textbooks, one for Chinese elementary school students and the other for students learning Chinese as a second language. We find that the DNW method significantly outperforms the others, implying that the efficiency of current learning methods of major textbooks can be greatly improved.

description: The efficient implementation of kinematics and dynamics models is a key to model based control of mechatronic systems such as robots and wearable assistive devices. This paper presents an approach for the derivation of these models in symbolic form for constrained systems based on the explicit elimination of the kinematic constraints using substitution variables with trigonometric expressions and the Lagrange equations of the second kind. This represents an alternative solution to using the implicit form of the constraints or using the explicit elimination at comparable computational effort. The method is applied to a novel exoskeleton designed for craftsmen force assistance, which consists of multiple planar closed kinematic loops and gear mechanisms.

description: Digital agriculture technologies represent a solution for improving productivity levels and environmental sustainability by collecting, integrating and analysing data with great potential from different sources. The potential disruptive impact of digital agriculture makes it particularly important to understand the mechanisms of adoption and diffusion of digital farming technologies. Indeed, the existing literature clearly shows that multiple factors involved in the decision-making process are responsible for farmers' technology adoption rate. However, their knowledge is still incomplete. Individual, technological, social, and economic factors influencing technology adoption at both farm and system levels can depict the overall decision-making process. The approach of this paper is to explore farmers' adoption process from the Italian stakeholders' perceptions of needs and demands for digital technologies. The main objective is to analyze the barriers to adoption and drivers to the diffusion of system innovations by using a combined qualitative research method with focus groups and semi-structured interviews.

Results from content analysis point out that a crucial precondition for embracing digital transformation is the interaction between different stakeholders, promoting cooperation as a key strategy. Collaborative efforts through technical support and training activities have the potential to moderate business risks, foster individual competitiveness and strengthen overall investment capacity in the agricultural sector.

Capabilities' Substitutability and the "S" Curve of Export Diversity

description: Product diversity, which is highly important in economic systems, has been highlighted by recent studies on international trade. We found an empirical pattern, designated as the "S-shaped curve", that models the relationship between economic size (logarithmic GDP) and export diversity (the number of varieties of export products) on the detailed international trade data. As the economic size of a country begins to increase, its export diversity initially increases in an exponential manner, but overtime, this diversity growth slows and eventually reaches an upper limit. The interdependence between size and diversity takes the shape of an S-shaped curve that an be fitted by a logistic equation. To explain this phenomenon, we introduce a new parameter called "substitutability" into the list of capabilities or factors of products in the tri-partite network model (i.e., the country-capability-product model) of Hidalgo et al. As we observe, when the substitutability is zero, the model returns to Hidalgo's original model but failed to reproduce the S-shaped curve. However, in a plot of data, the data increasingly resembles an the S-shaped curve as the substitutability expands. Therefore, the diversity ceiling effect can be explained by the substitutability of different capabilities.

description: Robotic tasks like welding or drilling with three translational and only two rotational degrees of freedom ("3T2R") are of high industrial relevance but are rather scarcely addressed in scientific publications. Existing solutions for the resolution of the functional redundancy of robotic manipulators with more than five axes performing these tasks either expand the full kinematic formulation or reduce it in intermediate steps. This paper presents an approach to reduce the kinematic formulation from the start to solve the problem in a simpler way. This is done by using a set of reciprocal Euler angles to describe the end-effector orientation and the orientation error in inverse kinematics.

description: The development of automated and autonomous vehicles requires highly accurate long-term maps of the environment. Urban areas contain a large number of dynamic objects which change over time. Since a permanent observation of the environment is impossible and there will always be a first time visit of an unknown or changed area, a map of an urban environment needs to model such dynamics. In this work, we use LiDAR point clouds from a large long term measurement campaign to investigate temporal changes. The data set was recorded along a 20 km route in Hannover, Germany with a Mobile Mapping System over a period of one year in bi-weekly measurements. The data set covers a variety of different urban objects and areas, weather conditions and seasons. Based on this data set, we show how scene and seasonal effects influence the measurement likelihood, and that multi-temporal maps lead to the best positioning results. © 2020 International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences - ISPRS Archives.

description: Torque load measurements play an important part in various engineering applications, as for automotive industry, in which the drive torque of a motor has to be determined. A widely used measuring method are strain gauges. A thin flexible foil, which supports a metallic pattern, is glued to the surface of the object the torque is being applied to. In case of a deformation due to the torque load, the change in the electrical resistance is measured. With the combination of constitutive equations the applied torque load is determined by the change of electrical resistance. The creep of the glue and the foil material, together with the temperature and humidity dependence, may become an obstacle for some applications Kapralov and Fesenko(1984). Thus, there have been optical and magnetical, as well as capacitive sensors introduced ). This paper discusses the general idea behind an electrostatic capacitive sensor based on a simple draft of an exemplary measurement setup. For better understanding an own electrostatical, geometrical and mechanical model of this setup has been developed.

description: (Uploaded by Plazi for the Bat Literature Project) Acoustic monitoring is a powerful technique for learning about the ecology of bats, but  understanding sources of variation in the data collected is important for unbiased  interpretation. The objectives of this dissertation were to investigate sources of variation  in acoustic monitoring and make recommendations for acoustic survey design and  analysis. I addressed this goal in three ways: i) variation resulting from differences in bat  detectors, ii) methods for objective identification of peak activity, and iii) the use of  stationary transects to address within-site spatial variation.  First, I compared variation of detection of echolocation calls among commonly available  bat detectors and found significant differences in distance and angle of detection.  Consequently, this source of variation should be taken into account when comparing  datasets obtained with different systems. Furthermore, choice of detector should be taken  into account when designing new studies.  Second, I investigated two statistical methods for identifying peaks in activity, percentile  thresholds and space-time scan statistic (SaTScan). Acoustic monitoring provides a  relative measure of activity levels and is rarely evaluated based on objective criteria, so  describing bat activity as "high" or "low" is useful only in context of the studies in  question. Percentile thresholds allow for peaks to be identified relative to a larger  distribution of activity levels. SaTScan identifies peaks in space and time that are  significantly higher than the background expectation of the dataset. Both methods are  valuable tools for replicable and objective identification of peak activity that can be  applied at various temporal and spatial scales. iii  Third, I examine how within-site spatial variation can impact estimates of bat activity. I  used a stationary transect of bat detectors to i) assess variation in patterns of activity at  each detector, ii) test whether spatial or temporal factors were more important for  explaining variation in activity, iii) explore what sampling effort in space and time is  required for species-specific activity levels. The picture of activity differs significantly  within a site depending on detector placement so it is important to use multiple detectors  simultaneously to collect accurate estimates of activity.

description: We investigate the ultracold reaction dynamics of magnetically trapped NH($X ^3Σ^-$) radicals using rigorous quantum scattering calculations involving three coupled potential energy surfaces. We find that the reactive NH + NH cross section is driven by a short-ranged collisional mechanism, and its magnitude is only weakly dependent on magnetic field strength. Unlike most ultracold reactions observed so far, the NH + NH scattering dynamics is non-universal. Our results indicate that chemical reactions can cause more trap loss than spin-inelastic NH + NH collisions, making molecular evaporative cooling more difficult than previously anticipated.

description: Chemical reaction networks govern polymer degradation and contain critical design information regarding specific susceptibilities, degradation pathways, and degradants. However, predicting reaction pathways and characterizing complete reaction networks has been hindered by high computational costs because of the vast number of possible reactions at deeper levels of network exploration. In the first section, an exploration policy based on Dijkstra's algorithm on YARP using the reaction rate as a cost function was shown to provide a tractable means of exploring the pyrolytic degradation network of a representative commodity polymer, PEG. The resulting network is the largest reported to date for this system and includes pathways out to all degradants observed in earlier mass spectrometry studies. The initial degradation pathway predictions were validated by complementary experimental analysis of pyrolyzed PEG samples by ESI-MS. These findings demonstrate that reaction network characterization is reaching sufficient maturity to be used as an exploratory tool for investigating materials degradation and interpreting experimental degradation studies.

description: Kommunikationsleitungen und Stromversorgungskabel sind ein wichtiges Einfallstor für gestrahlte elektromagnetische Störungen in angeschlossene Geräte. Oftmals wirkt nicht nur eine einzelne Leitung als Antenne, sondern mehrere Leitungen bilden zusammen ein entsprechendes Leitungsnetzwerk. Zur Berechnung der Einkopplung eines einfallenden Feldes auf ein Leitungsnetzwerk kann die klassische Leitungstheorie genutzt werden. Das Feld wird dabei durch eine ebene Welle mit einer bestimmten Einfallsrichtung und Polarisation angenähert. Durch die Überlagerung vieler ebener Wellen mit beliebigen Einfallsrichtungen und Polarisationen lassen sich auch sogenannte statistische Felder nachbilden, wie sie z. B. in Modenverwirbelungskammern vorkommen. In diesem Beitrag soll ein vorhandenes numerisches Simulationsverfahren für Leitungsnetzwerke [2, 4] auf Basis der BLT-Gleichungen messtechnisch validiert werden.

description: Given two maps between smooth manifolds, the obstruction to removing their coincidences (via homotopies) is measured by minimum numbers. In order to determine them we introduce and study an infinite hierarchy of Nielsen numbers N_i, i = 0, 1, ..., \infty. They approximate the minimum numbers from below with decreasing accuracy, but they are (in principle) more easily computable as i grows. If the domain and the target manifold have the same dimension (e.g. in the fixed point setting) all these Nielsen numbers agree with the classical definition. However, in general they can be quite distinct. While our approach is very geometric the computations use the techniques of homotopy theory and, in particular, all versions of Hopf invariants (a la Ganea, Hilton, James..). As an illustration we determine all Nielsen numbers and minimum numbers for pairs of maps from spheres to spherical space forms. Maps into even dimensional real projective spaces turn out to produce particularly interesting coincidence phenomena.

description: We present visible spectroscopic observations of a near-earth object (NEO) 2012 DA14. The asteroid 2012 DA14 came close to the surface of the Earth on February 15, 2013 at a distance of 27,700 km. Its estimated diameter is around 45 m. The physical properties of such a small asteroid have not yet been well determined. The close encounter is a good opportunity to conduct a variety of observations. The purpose of this paper is to deduce the taxonomy of 2012 DA14 by visible spectroscopic observations using the 0.4 m f/10 telescope at the Fujii Kurosaki Observatory. We conclude that the taxonomy of 2012 DA14 is an L-type in the visible wavelength region. In addition, we refer to the availability of a small, accessible telescope for NEOs smaller than 100 m.

The speech is fluent when person's speech flows easily and smoothly. Sounds combine into syllable, syllables mix together into words and words link into sentences with little effort. When someone's speech is dysfluent, it is irregular and does not flow effortlessly. Therefore, a dysfluency is a break in the smooth, meaningful flow of speech. Stuttering is one such disorder in which the fluent flow of speech is disrupted by occurrences of dysfluencies such as repetitions, prolongations, interjections and so on. In this work we have considered three types of dysfluencies such as repetition, prolongation and interjection to characterize dysfluent speech. After obtaining dysfluent and fluent speech, the speech signals are analyzed in order to extract MFCC features. The k-Nearest Neighbor (k-NN) and Support Vector Machine (SVM) classifiers are used to classify the speech as dysfluent and fluent speech. The 80% of the data is used for training and 20% for testing. The average accuracy of 86.67% and 93.34% is obtained for dysfluent and fluent speech respectively.

description: Dieser Beitrag gibt einen Überblick über die Einsatzmöglichkeiten und Vorgehensweisen der Simulation in der Leistungselektronik, speziell für Hochvoltsysteme. Der Beitrag richtet sich nicht an Spezialisten der EMV Simulation sondern vielmehr an diejenigen, die wissen wollen, welche Hebel die Leistungselektroniksimulation entfalten kann. Diskutiert werden dabei die Partitionierung eines komplexen Aufbaus, die zu verwendenden geeigneten Lösungsverfahren, mögliche Ziele der Modellierung sowie der Einfluss des Produktdesignprozesses auf die Möglichkeiten der Simulation. Als Beispiel wird am Ende des Beitrages ein 48V System per Simulation untersucht. Ziel ist, eine Abschätzung zu geben, unter welchen Bedingungen die Leistungselektroniksimulation sinnvoller Bestandteil der Produktentwicklung ist.

description: We investigate the influence of the topography on the lake equations which describe the two-dimensional horizontal velocity of a three-dimensional incompressible flow. We show that the lake equations are structurally stable under Hausdorff approximations of the fluid domain and $L^p$ perturbations of the depth. As a byproduct, we obtain the existence of a weak solution to the lake equations in the case of singular domains and rough bottoms. Our result thus extends earlier works by Bresch and Métivier treating the lake equations with a fixed topography and by Gérard-Varet and Lacave treating the Euler equations in singular domains.

description: The present paper focuses on simplicity as a linguistic category of epistolary communication in eighteenth-­century Russia. It shows how Radishchev, known after the publication of The Journey from Petersburg to Moscow as a writer with an inflated style, used simplicity in his letters from exile to build his epistolary ‘ideal self’ and stage the relationship he was longing to have with his former patron and protector Count Alexander Vorontsov.

description: Zur Sicherstellung der Schirmwirkung von geschirmten Räumen, Anlagen und Geräten sind Leitungsdurchführungen ein wichtiges Konstruktionselement. Ohne besondere Vorkehrungen an der Durchführungsstelle der Leitung in den Raum kann die Schirmeffektivität (SE) signifikant reduziert werden, besonders wenn Hohlraumresonanzen angeregt werden. Zwar wird die Problemstellung der Leitungsdurchführung in der Literatur behandelt [1], [2], [3], [4] und es werden qualitative Abhilfemaßnahmen vorgestellt wie z. B. eine 360°-Leitungsschirmauflegung oder der Einsatz von EMV-Filtern (Abb. 1), jedoch fehlen quantitative Untersuchungen, die das Phänomen der Hohlraumresonanzen einschließen. Die in dieser Arbeit vorgestellten quantitativen Ergebnisse greifen einerseits auf die Erkenntnisse aus [5] zurück und andererseits werden Messungen an einem praktischen Modell durchgeführt. Der Hintergrund dieser Arbeit liegt in der Verbesserung der Störsicherheit von elektronischen Systemen in metallischen Schiffsräumen in einer IEMI-Umgebung (Intentional Electromagnetic Interference).
title: Memory and Identity in Russian Noblewomen’s Francophone Travel Narratives (1790-­1842)
Creators: name: Murphy, Emilie
Publisher: name: AvtobiografiЯ
Year: 2013

description: This article demonstrates the numerous ways in which recollective and habit memory are used by Russian noblewomen as a device to shape social, cultural and national identity in their francophone travel narratives (1790-­‐1842). Practices of collective memory are closely implicated with those of travel in women’s leisured journeys to Western Europe and both memory and travel are allied with processes of personal and collective identity formation. Drawing on Maurice Halbwachs’s theory of collective memory, this article argues that the women use recollection to construct their identity as members of various social groups: trans-­European high society, family, nation and religious and school communities. They draw on memory in diverse ways in their texts and recollections are expressed in spatial, emotional, historical, social, cultural, religious and national terms. Remembrance offers resources for the women’s transformation from individuals into a group with a collective identity.

description: The present study deals with oxidation behavior under residual stress of shot-peened plates of "commercially pure" zirconium exposed for 30 min at 650 C. The influence of the shot-peening on a pre-oxidized material is presented. The results have been used to determine the influences of these chemical (preoxidation) and mechanical (shot-peening) treatments on the high temperature oxidation of zirconium. The oxygen profile was revealed using micro-hardness techniques and confirmed by SEM-EDS techniques. After pre-oxidation the samples were first resurfaced then shot-peened in order to introduce residual stress. A significant increase of the hardness of about 400 HV was observed on pre-oxidized shot-peened samples. Thermogravimetric analysis for 30 min at 650 C under 200 mbar O2 showed a significantly slower oxidation rate for shot-peened samples. A comparison with our computations points out the role of the residual stresses on the diffusion and, consequently, on the oxidation.

description: The paper will follow the purposes and the literary patterns of the Diary written by V.K. Kiukhel’beker during the years of the imprisonment (1828-­1835) and the Siberian exile (1835-­1846). The Diary becomes for the poet the unique substitute of the literary and professional milieu from which he was pull up while he considered himself as one of the prominent critics and poets of the young generation. In jail, and later in the Siberian exile, Kiukhel’beker creates an alternative literary world, with internal polemics, discussions, reviews of books and articles, memoirs and perspectives concerning the present and the future of the Russian literature, as if he still took an active part in the cultural life of his Country. Therefore, there are in the writer’s Diary some par­ticularities differentiating it from the general model of diary: at first, the relationship between the author and the diary is something like a mix of typical intimate self-­writing and a simulation of public ‘comparison’ (very close to a journal column), where reality and fantasy strictly join and mix with each other; secondly, an interesting peculiarity of this Diary is the predominance of the future tense over the past: Kiukhel’beker is scarcely interested in his own past years, and only partially in his troubled present: he often lives in an ‘eternal’ dimension, writing his Diary for the posterity. Hence, the Diary acquires a didactical or ever prophetical tone, which is typical for Kiukhel’beker’s self-perception.
