description: Cloud computing provides IT infrastructures and services via networks, and it enables economic potentials for end users as well as a focus on core competencies. In addition to its extensive potentials, cloud computing in general, and hybrid cloud computing in particular, pose new challenges in the negotiation and formulation of Service Level Agreements, as well as in the monitoring of and compliance with contractual requirements. An understanding of cloud service and deployment models, perspectives, roles, and contractual terms is essential for a successful and compliant adoption of hybrid clouds. Consequently, this paper proposes the novel HySLAC model, focusing on service level agreement compliance in hybrid cloud architectures. Based on eight model requirements and a systematic literature review, the HySLAC model was conceptualized with UML 2.0. It comprises eight UML classes and five associated enumerations, and it is instantiated by means of a case study. The model offers scientific and practical application capabilities for the analysis of service components as well as hybrid cloud service compositions, and it opens up potentials for decision support.

description: We study the spectral properties of Spontaneous Parametric Down Conversion in a periodically poled waveguided structure of KTP crystal pumped by ultra-short pulses. Our theoretical analysis reveals a strongly multimode and asymmetric structure of the two-photon spectral amplitude for type-II SPDC. Experimental evidence, based on Hong-Ou-Mandel polarization interference with narrowband filtering, confirms this result.

description: The concepts of Microservices and Organic Computing contribute to a fully distributed architecture of the Internet of Things (IoT), avoiding single points of failure through massive service distribution. The distribution and the lack of structure, however, come with large communication overheads. We discuss the necessity of structure in IoT networks focusing on the problem of trust handling, specifically analyzing the certificate chain discovery problem. Moreover, we provide an argument towards solving the certificate chain discovery problem in the same manner as the service discovery problem in a combined, semi-structured approach. By numerical analysis we show that the introduction of a hierarchy can avoid scalability problems and that resource directories used for service discovery can serve as hierarchical entities.

description: We present the exact calculus of the gravitational potential and acceleration along the symmetry axis of a plane, homogeneous, polar cell as a function of mean radius a, radial extension e, and opening angle f. Accurate approximations are derived in the limit of high numerical resolution at the geometrical mean of the inner and outer radii (a key-position in current FFT-based Poisson solvers). Our results are the full extension of the approximate formula given in the textbook of Binney & Tremaine to all resolutions. We also clarify definitely the question about the existence (or not) of self-forces in polar cells. We find that there is always a self-force at radius except if the shape factor a.f/e reaches ~ 3.531, asymptotically. Such cells are therefore well suited to build a polar mesh for high resolution simulations of self-gravitating media in two dimensions. A by-product of this study is a newly discovered indefinite integral involving complete elliptic integral of the first kind over modulus.

description: The project An Agile Approach Towards Computational Modeling of Historiographical Uncertainty is building a taxonomy of historiographical uncertainty. We are focusing on early medieval texts as our case studies, because they are characterised by a high degree of “high stakes” uncertainty and a varied historiography characterised by a vivid debate. The additional factor of the manuscript text-transmission ensues that also the material aspect of the textual study will be covered in our attempt to build an adaptable taxonomy of historiographical uncertainty. Computational humanities need a robust methodological platform, that can be applied to a wide variety of projects. Uncertainty in general and geographical uncertainty in particular stand as the crucial aspects of this platform. We investigate a methodology of visualising geographical locales in historical texts and their historiographies that explicitly models uncertainty in.

description: The Padé table of $\phantom{}_2F_1(a,1;c;z)$ is normal for $c>a>0$ (cf. \cite{3}). For $m \geq n-1$ and $c \notin {\zz}^{\phantom{}^-}$, the denominator polynomial $Q_{mn}(z)$ in the $[m/n]$ Padé approximant $P_{mn}(z)/Q_{mn}(z)$ for $\phantom{}_2F_1(a,1;c;z)$ and the remainder term $Q_{mn}(z)\phantom{}_2F_1(a,1;c;z)-P_{mn}(z)$ were explicitly evaluated by Padé (cf. \cite{2}, \cite{5} or \cite{7}). We show that for $c>a>0$ and $m\geq n-1$, the poles of $P_{mn}(z)/Q_{mn}(z)$ lie on the cut $(1,\infty)$. We deduce that the sequence of approximants $P_{mn}(z)/Q_{mn}(z)$ converges to $\phantom{}_2F_1(a,1;c;z)$ as $m \to \infty$, $ n/m \to ρ$ with $0a>0$

description: We present atomistic molecular dynamics results for fully hydrated bilayers composed of ceramide NS-24:0, free fatty acid 24:0 and cholesterol, to address the effect of the different components in the stratum corneum (the outermost layer of skin) lipid matrix on its structural properties. Bilayers containing ceramide molecules show higher in-plane density and hence lower rate of passive transport compared to phospholipid bilayers. At physiological temperatures, for all composition ratios explored, the lipids are in a gel phase with ordered lipid tails. However, the large asymmetry in the lengths of the two tails of the ceramide molecule leads to a fluid like environment at the bilayer mid-plane. The lateral pressure profiles show large local variations across the bilayer for pure ceramide or any of the two component mixtures. Close to the skin composition ratio, the lateral pressure fluctuations are greatly suppressed, the ceramide tails from the two leaflets interdigitate significantly, the depression in local density at the inter-leaflet region is lowered, and the bilayer have lowered elastic moduli. This indicates that the observed composition ratio in the stratum corneum lipid layer is responsible for both the good barrier properties and the stability of the lipid structure against mechanical stresses.

Subjects: subject: Crisis Management
subject: Enterprise Architecture
subject: Lufthansa

description: In this paper we argue that the Enterprise Architect (EA) should be considered as a crisis manager. In times of a crisis organizations must create a holistic view on the situation and evaluate the proposed measures. Evaluation will be based on experience, data, upfront-created scenarios and assessments of risks, cost and benefits. The EA is already engaged in processes such as Continuity Management, Risk Management, IT Security, Business Process Management, IT Strategy, and others. Therefore, we propose that the EA is one good candidate (not the only one) for handling organizational crises. This paper presents a model of overall crisis management that incorporates an enterprise architecture view as well as related dimensions of crisis management: the ability to control a crisis, the level of communication during and after a crisis, the type of change brought by a crisis, the crisis' outcomes, its distribution within an enterprise, and an organization's criticality of business functions. Finally, we highlight how the EA role supports crisis management at Lufthansa, a top German aviation company.
Diapycnal mixing and the internal wave field north of the Kerguelen Plateau

Publisher: name: University Of Tasmania

Subjects: Physical oceanography

description: Dissipating internal waves are the main source of mixing in the stratified ocean. Recent observational and modelling studies in the Southern Ocean primarily associate the generation of internal waves with either wind forcing or with rough topography. This work explores the nature of mixing and its sources north of the Kerguelen Plateau, a large topographic feature in the Southern Ocean. Based on novel observations, we present the distribution and intensity of mixing, and the internal wave field properties. This thesis includes (i) a regional description of the Kerguelen Plateau oceanographic characteristics; (ii) estimates of mixing and its sources; and (iii) a study of the internal wave field in the vicinity of the Plateau. The data consist of 914 temperature, salinity, pressure and horizontal velocity profiles from Electromagnetic Autonomous Profiling Explorer (EM-APEX) floats deployed northeast of the Kerguelen Plateau in 2008. We are able to estimate diapycnal mixing in the upper 1600m of the water column. To estimate mixing, we apply both a Thorpe-scale analysis on density inversions and a shear-strain parameterization method and compare the estimates with direct microstructure measurements.

description: Machine vision systems based on deep convolutional neural networks are increasingly utilized in digital humanities projects, particularly in the context of art-historical and audiovisual data. As research has shown, such systems are highly susceptible to bias. We propose that this is not only due to their reliance on biased datasets but also because their perceptual topology, their specific way of representing the visual world, gives rise to a new class of bias that we call perceptual bias. Perceptual bias, we argue, affects almost all currently available “off-the-shelf” machine vision systems, and is thus especially relevant for digital humanities applications, which often rely on such systems for hypothesis building. We evaluate the nature and scope of perceptual bias by means of a close reading of a visual analytics technique called “feature visualization” and propose to understand the development of critical visual analytics techniques as an important (digital) humanities challenge, situated at the interface of computer science and visual studies.

description: We present Spitzer photometric (IRAC and MIPS) and spectroscopic (IRS low resolution) observations for 314 stars in the Formation and Evolution of Planetary Systems (FEPS) Legacy program. These data are used to investigate the properties and evolution of circumstellar dust around solar-type stars spanning ages from approximately 3 Myr to 3 Gyr. We identify 46 sources that exhibit excess infrared emission above the stellar photosphere at 24um, and 21 sources with excesses at 70um. Five sources with an infrared excess have characteristics of optically thick primordial disks, while the remaining sources have properties akin to debris systems. The fraction of systems exhibiting a 24um excess greater than 10.2% above the photosphere is 15% for ages < 300 Myr and declines to 2.7% for older ages. The upper envelope to the 70um fractional luminosity appears to decline over a similar age range. The characteristic temperature of the debris inferred from the IRS spectra range between 60 and 180 K, with evidence for the presence of cooler dust to account for the strength of the 70um excess emission. No strong correlation is found between dust temperature and stellar age. Comparison of the observational data with disk models containing a power-law distribution of silicate grains suggest that the typical inner disk radius is > 10 AU. Although the interpretation is not unique, the lack of excess emission shortwards of 16um and the relatively flat distribution of the 24um excess for ages <300~Myr is consistent with steady-state collisional models.

description: Stochastic mass transport models are usually described by specifying hopping rates of particles between sites of a given lattice, and the goal is to predict the existence and properties of the steady state. Here we ask the reverse question: given a stationary state that factorizes over links (pairs of sites) of an arbitrary connected graph, what are possible hopping rates that converge to this state? We define a class of hopping functions which lead to the same steady state and guarantee current conservation but may differ by the induced current strength. For the special case of anisotropic hopping in two dimensions we discuss some aspects of the phase structure. We also show how this case can be traced back to an effective zero-range process in one dimension which is solvable for a large class of hopping functions.

description: Nach wie vor sind große Unternehmen Vorreiter der Digitalisierung. Doch der Mittelstand erschließt in immer stärkerem Maße seine digitalen Potentiale und holt auf. So planten im Jahr 2019 38,8% der in einer Studie der KfW befragten kleinen Unternehmen mindestens zwei Digitalisierungsvorhaben in den kommenden zwei Jahren durchzuführen und weitere 28% dachten hierüber nach. Vor diesem Hintergrund spielt auch Künstliche Intelligenz für Mittelständler eine immer wichtigere Rolle, denn laut einer Studie des Bundesministeriums für Wirtschaft (BMWi) ist die Implementierung von KI im Mittelstand eine zwingende Voraussetzung, um auf dem internationalen Markt wettbewerbsfähig zu bleiben. Dabei liegen die Potentiale von KI im Mittelstand in sehr verschiedenen Bereichen wie z.B. Optimierung der Distribution und Logistik, gesteigerte Prozesseffizienz oder zielgenauere Werbung. Insbesondere Technologien wie intelligente Automatisierung, intelligente Sensorik oder intelligente Assistenzsysteme sind hierbei von großer Bedeutung. Der Workshop „Künstliche Intelligenz für kleine und mittlere Unternehmen“ hat das Ziel, Forscher und Anwender von KI-Ansätzen zusammenzubringen, den Wissenstransfer zwischen den beiden Gruppen sowie den einzelnen Gruppen untereinander zu ermöglichen und KI in KMU greifbar zu machen. Dabei adressiert der Workshop zwei Schwerpunkte: Einerseits sollen Forschungsansätze präsentiert werden, die einen starken Bezug zu den Herausforderungen für kleine und mittlere Unternehmen im Bereich KI haben oder sich mit leichtgewichtigen KI-Anwendungen, die sich einfach und ohne großen Aufwand bei KMU integrieren lassen, beschäftigen. Andererseits können aber auch erfolgreich abgeschlossene oder laufende Pilotprojekte vorgestellt werden, die einen ersten Einblick in die Wirkung von KI in der Praxis geben und aufzeigen, welche Herausforderungen sich bei der Umsetzung von KI ergeben. Die folgenden vier Beiträge des Workshops stellen aktuelle KI-Ansätze in unterschiedlichen Anwendungsfeldern und an unterschiedlichen Anwendungsbeispielen vor. Diese reichen vom Applikations-und Dosierprozess von Schmierfetten in der Produktion über die unternehmensübergreifende Nutzung von Predictive Manintenance Daten, die Duplikatenerkennung im CRM und CEM bis hin zu Empfehlungen von Radio Programmen. Dabei kommen verschiedene Algorithmen und Verfahren, wie z.B. K-Means Clustering, Federated Learning sowie Sequential Model Based Optimization bzw. Bayes’sche Optimierung zur Anwendung.
Quantum models of classical mechanics: maximum entropy packets

description: In a previous paper, a project of constructing quantum models of classical properties has been started. The present paper concludes the project by turning to classical mechanics. The quantum states that maximize entropy for given averages and variances of coordinates and momenta are called ME packets. They generalize the Gaussian wave packets. A non-trivial extension of the partition-function method of probability calculus to quantum mechanics is given. Non-commutativity of quantum variables limits its usefulness. Still, the general form of the state operators of ME packets is obtained with its help. The diagonal representation of the operators is found. A general way of calculating averages that can replace the partition function method is described. Classical mechanics is reinterpreted as a statistical theory. Classical trajectories are replaced by classical ME packets. Quantum states approximate classical ones if the product of the coordinate and momentum variances is much larger than Planck constant. Thus, ME packets with large variances follow their classical counterparts better than Gaussian wave packets.

description: In the framework of the Centre of Excellence in Simulation of Weather and Climate in Europe (ESiWACE), a ground-breaking configuration for EC-Earth - a European community Earth-System Model – has been developed. In the atmosphere, the horizontal domain is based on a spectral truncation of the atmospheric model (IFS) at T1279 together with 91 vertical levels. The ocean component (NEMO) is run on the so-called ORCA12 tripolar (cartesian) grid at a horizontal resolution of about 1/12°, with 75 vertical levels. In this talk, we will present the work done to develop this configuration, the computational challenges faced and the usage of the Barcelona Supercomputing Center (BSC) performance tools to analyse and profile the code. Finally, we will present some computational improvements regarding code execution and improved I/O management, currently developed in the Computational Earth Sciences team (CES) to increase the performance of this configuration.
An ecological analysis of voting behavior in Vancouver
Creators: name: Munton, Donald James
Publisher: name: University of British Columbia
Year: 2011

description: Local elections have received little attention in the literature of political science, either as an important component of city politics, or as a source of data on voting behavior. The present exploratory study, as merely one step towards redressing this situation, attempts to identify and analyze some of the political and social cleavages that underlie electoral politics in the city of Vancouver. The phenomena investigated as dependent variables include registration, turnout, ballot spoiling, non-use of votes, referenda voting, and candidate-party voting. The independent variables are the common census-derived socioeconomic characteristics of voters such as age, sex, marital status, religion, ethnicity, education level, occupation, and income. On the basis of a review of some important related studies, a simple model is proposed that sets out a theoretical relationship between these characteristics and voting behavior. The research method employed in the study is ecological analysis which, despite some inherent limitations, provides a suitable tool for the exploration of this relationship through correlation and regression techniques. A number of hypotheses are formulated from the data, but others, obtained from existing studies, have also been tested. The main findings of the present paper are twofold. Firstly, significant and generally explicable cleavages between broad socio-economic groups are revealed with respect to each of the dependent variables. Thus, for example, it is shown that each of the political parties in the city has a more or less solid base of support in voters of a particular socio-economic level. The second general conclusion, closely tied to the first, is that each of the broad groupings has a reasonably consistent and explicable pattern of behavior. Persons in the lowest socio-economic status group, for example, tend less to register and to vote, tend more to spoil ballots and leave votes unused, and tend to oppose referenda issues, as well as tending to vote for certain candidates. From the data and subsequent analysis, a typology is put forward classifying local voter orientation as being either purposive, maintaining, or protesting in nature. Finally, in part employing this typology as an explanatory mechanism, two general hypotheses are proposed which attempt to relate patterns of voting behavior firstly, to the decision-making output of Vancouver's political system and secondly, to persistence and change in the structure of the local party system.

description: To survive in global competition with increasing cost pressure, manufacturing companies must continuously optimize their manufacturing-related processes. Thereby, process mining constitutes an important data-driven approach to gain a profound understanding of the actual processes and to identify optimization potentials by applying data mining and machine learning techniques on event data. However, there is little knowledge about the feasibility and usefulness of process mining specifically in manufacturing companies. Hence, this paper provides an overview of potential applications of process mining for the analysis of manufacturing-related processes. We conduct a systematic literature review, classify relevant articles according to the Supply-Chain-Operations-Reference-Model (SCOR-model), identify research gaps, such as domain-specific challenges regarding unstructured, cascaded and non-linear processes or heterogeneous data sources, and give practitioners inspiration which manufacturing-related processes can be analyzed by process mining techniques.

description: Dark Matter annihilations after recombination and during the epoch of structure formation deposit energy in the primordial intergalactic medium, producing reionization and heating. We investigate the constraints that are imposed by the observed optical depth of the Universe and the measured temperature of the intergalactic gas. We find that the bounds are significant, and have the power to rule out large portions of the `DM mass/cross section' parameter space. The optical depth bound is generally stronger and does not depend significantly on the history of structure formation. The temperature bound can be competitive in some cases for small masses or the hadronic annihilation channels (and is affected somewhat by the details of structure formation). We find in particular that DM particles with a large annihilation cross section into leptons and a few TeV mass, such as those needed to explain the PAMELA and FERMI+HESS cosmic ray excesses in terms of Dark Matter, are ruled out as they produce too many free electrons. We also find that low mass particles (

description: Spätestens seit Aufkommen der Corona-Pandemie spielt der Einsatz von Videos im Rahmen der Hochschullehre eine zentrale Rolle. Dabei werden Lehrende, die erstmalig ein Video produzieren, mit zahlreichen Herausforderungen konfrontiert. Serviceeinrichtungen der Hochschulen sind gefragt, um Lehrende mittels didaktischer Beratung und technischer Expertise zu unterstützen. Doch die zeitlichen Kapazitäten aller Beteiligten sind knapp. Mit dem Ziel, die Videoproduktion an Hochschulen zu fördern, hat ein interdisziplinäres Team der Universität Osnabrück einen Design Thinking Prozess mit zwei Fokusgruppeninterviews durchgeführt, um einen adaptiven Wegweiser für Hochschullehrende zu entwickeln. Der Wegweiser wird zukünftig in einen digitalen Konfigurator überführt, der Lehrenden als erste Anlaufstelle, zentrale Informationsplattform und Hilfe zur Selbsthilfe dienen soll. Zudem soll er die hochschulinternen Serviceeinrichtungen entlasten, indem er eine erste Orientierungshilfe bietet und einen Output liefert, der als Ausgangspunkt für persönliche Beratungsgespräche genutzt werden kann. Die Grundstruktur des Wegweisers kann auf andere Hochschulen übertragen werden, um weitere, hochschulspezifische Konfiguratoren zu entwickeln.

description: Dieses Paper beschäftigt sich mit der Energie-Effizienz von Video-Streaming-Diensten. Zunächst wird die grundlegende Funktionsweise beschrieben, was die dahinterliegenden Technologien mit einbezieht. Neben der Erwähnung der bekanntesten Video-Streaming-Plattformen wird insbesondere auf Netflix als Fallbeispiel eingegangen. Zunächst werden die aktuellen Daten ermittelt und verschiedene Studien zur Verbesserung der Energie-Effizienz betrachtet. Außerdem wird analysiert, inwiefern in bestimmten Studien aus falschen Annahmen schlechte Prognosen ermittelt werden. Letztendlich werden Vorschläge präsentiert, wie die Energie-Effizienz nachhaltig und stetig weiterentwickelt werden kann. Dabei wird speziell eine Unterteilung in Unternehmen und Endverbraucher herangezogen, um die Möglichkeiten detaillierter zu spezifizieren.
Shuttling heat across 1D homogenous nonlinear lattices with a Brownian heat motor

description: We investigate directed thermal heat flux across 1D homogenous nonlinear lattices when no net thermal bias is present on average. A nonlinear lattice of Fermi-Pasta-Ulam-type or Lennard-Jones-type system is connected at both ends to thermal baths which are held at the same temperature on temporal average. We study two different modulations of the heat bath temperatures, namely: (i) a symmetric, harmonic ac-driving of temperature of one heat bath only and (ii) a harmonic mixing drive of temperature acting on both heat baths. While for case (i) an adiabatic result for the net heat transport can be derived in terms of the temperature dependent heat conductivity of the nonlinear lattice a similar such transport approach fails for the harmonic mixing case (ii). Then, for case (ii), not even the sign of the resulting Brownian motion induced heat flux can be predicted a priori. A non-vanishing heat flux (including a non-adiabatic reversal of flux) is detected which is the result of an induced dynamical symmetry breaking mechanism in conjunction with the nonlinearity of the lattice dynamics. Computer simulations demonstrate that the heat flux is robust against an increase of lattice sizes. The observed ratchet effect for such directed heat currents is quite sizable for our studied class of homogenous nonlinear lattice structures, thereby making this setup accessible for experimental implementation and verification.

description: Das Geschäftsprozessmanagement leistet seit mehreren Jahrzehnten einen wichtigen Beitrag für den Unternehmenserfolg. Im Rahmen der Aufgaben des Geschäftsprozessmanagements nimmt die Prozessmodellierung eine zentrale Stellung ein. Dennoch haben insbesondere kleine und mittelständische Unternehmen Schwierigkeiten bei der erfolgreichen Umsetzung. Dies liegt unter anderem an einer fehlenden Prozessmanagementabteilung, aber auch an vorwiegend dezentral organisierten Modellierungseinheiten. Dieser Beitrag gewährt Einblick in die aktuelle Umsetzung der Prozessmodellierung in deutschsprachigen Unternehmen und bezieht sich dabei auf 26 durchgeführte Interviews, mit Experten aus Forschung und Praxis. Dabei wird deutlich, dass sich nach wie vor keine Notationssprache als Modellierungsstandard etablieren konnte und auch die Beurteilung der Qualität der Prozessmodelle weiterhin zweitrangig bleibt. Ferner wird ersichtlich, dass aus Sicht der Praxis Handlungsbedarf beim Aufbau von Prozesshäusern besteht, da es bis heute an einer standardisierten Lösung für eine personen-und anforderungsspezifische Navigation fehlt. Im Rahmen der Studie werden durch eine induktive Vorgehensweise fünf Gestaltungsfaktoren abgeleitet, die für eine erfolgreiche Umsetzung der Prozessmodellierung von Bedeutung sein können.

description: We have for the first time calculated low-energy electronic structure both in paramagnetic and magnetic state as well as zero-temperature properties and thermodynamics. We consistently described magnetic properties of CoO in agreement with its insulating ground state. The orbital moment of 1.42 mu_B gives 35 contribution to the total moment of 4.04 mu_B at T =0 K. We have calculated from this low-energy electronic structure the temperature dependence of the specific heat being in nice agreement with experimental data. In our approach CoO is an insulator independently on distortions and the magnetic order.

description: Probiotic supplements have been shown to improve bone health in animal models, although it remains uncertain whether these beneficial effects extend to humans. We undertook a systematic review of the literature to determine the effects of probiotic interventions on skeletal outcomes in postmenopausal women. MEDLINE, EMBASE, CENTRAL, and the Cochrane Database of Systematic Reviews were searched from inception to October 2020 for controlled trials comparing the effects of probiotic-containing supplements with placebo on bone mineral density (BMD) or bone turnover markers. Risk of bias was assessed using the Cochrane Risk of Bias 2 Tool. Of 338 records identified, six randomized, placebo-controlled trials (n = 632) were eligible for inclusion. All studies assessed postmenopausal women for durations of 6–12 months; three were considered to be at high risk of bias. Four studies examined Lactobacillus-containing probiotics, one assessed a proprietary blend of lactic acid bacteria, and one evaluated Bacillus subtilis. Effects of probiotic interventions on BMD were inconsistent, with the majority of studies demonstrating no benefit at the spine or hip. Probiotic effects on bone turnover markers were similarly heterogeneous. High quality studies are needed to determine whether probiotic interventions have a role in maintaining bone health in humans.
