description: In Business Process Management (BPM), graphical process modelling plays an important role because process models can significantly support BPM endeavors in many different ways. Hence, it is also crucial in the context of learning and teaching BPM. Graphical modelling in general is also a curricular core component of higher education in related disciplines such as information systems engineering or software engineering. There are numerous concepts and tools which support learning and teaching of graphical modelling, but most of them have so far been isolated from each other and are used only locally. In order to increase the quality of learning and teaching in modelling courses, it is desirable to better integrate these approaches and identify commonalities. This paper discusses several challenges of integrating learning and teaching approaches for graphical modelling and outlines an approach to a solution that is currently pursued in the ongoing research project KEA-Mod.

description: Die Zeitreihenanalyse ist für Umweltwissenschaften ein wichtiges Werkzeug, um Systeme zu charakterisieren, da sich in den Zeitreihen Signale, welche von unterschiedlichen Einflussgrößen herrühren, wiederfinden lassen. Ein Clustering kann helfen ähnliche Dynamiken zu gruppieren um so entsprechende Einflussgrößen zu erkennen und deren Einflussbereich zu charakterisieren. Wir stellen einen unüberwachten Ensemble-Modellierungsansatz für das Clustering von Umweltzeitreihen auf der Grundlage ihrer Dynamik vor. Der Feature-basierte Ansatz erlaubt es auch heterogene Datensätze zu nutzen, das Clustering der Features erfolgt schließlich auf der Basis von Self-Organizing-Maps. Der Ensemble-Ansatz reduziert die Willkür bei der Featureauswahl und erhöht die Robustheit des Endergebnisses. Die Ergebnisse einer beispielhaften Anwendung im Grundwasserbereich zeigen, dass die vorgestellte Methodik adaptiv in der Lage ist, homogene Gruppen von Zeitreihen-Dynamiken zu identifizieren.

subject: Creative and professional writing

description: This book is a linked collection of original short stories that follow a group of people who, in the late-nineties, spent their adolescent Sundays together at a Chinese School in Portland, Oregon. The stories reach as far back in time as the Nanjing Massacre, and, at times, extend into the near future. Each piece tells the story of a different individual, focusing on one or multiple aspects of family, friendship, obligation, love, and desire. As a whole, the collection explores ethnicity and sexuality. It attempts to investigate the experiences of young Asian Americans in modern society, and to question what it means to be a family.

description: Three improved thiophosphoroselenenylation procedures of CH-acids, including derivatives of malonic and acetyl-, phosphono-, 4-nitrophenyl- and 3-pyridylacetic acids, have been described and compared to previously reported thiophosphoroselenylation of diethyl malonate using bis(disopropoxyphosphinothioyl)diselenide alone or with the aid of methyl iodide. The use of iodine makes it possible to utilize both equivalents of the selenenylating agent. The procedures work well for the majority of nucleophiles in a pKa range between more acidic malononitrile or Meldrum acid and less acidic phenylacetates. The reaction carried out on diethyl malonate in boiling rectified ethanol yields selenoacetate, which cannot be obtained by direct phosphoroselenenylation. Crystal structure of one of the selenomalonamides confirms the stabilization effects of both carbonyl oxygens on selenium atom. The P-Se bond splitting, using TBAF in 3-molar excess in the presence of alkylating agent yields the respective C,Se-dialkyl derivatives.

description: Nitrat im Grundwasser stellt weltweit unter anderem für die Trinkwasserversorgung ein großes Problem dar. Die Verteilung von Nitrat im Grundwasser ist dabei das Ergebnis eines komplexen Zusammenspiels vieler Einflussfaktoren, welches sich mit herkömmlichen Modellen für große Gebiete aufgrund der hohen Komplexität der Domäne nur schwer modellieren lässt. KI-Anwendungen, insbesondere Neuronale Netze bzw. Deep Learning Verfahren, lassen als datenbasierte Modelle, die komplexe Zusammenhänge aus einer großen Datenmenge extrahieren und übertragen können, hier einen deutlichen Mehrwert bei der zeitlich-räumlichen Vorhersage von Nitratwerten erwarten. Im vorliegenden Projekt soll daher ein übergreifendes System entwickelt werden, welches KI Verfahren mit Methoden der Umweltinformatik und speziell der Wasserdomäne kombiniert. Hierzu kommen State-of-the-Art Machine Learning Methoden wie Convolutional Neural Networks und Long short-term Memory Netzwerke zum Einsatz, um so eine verbesserte räumliche und zeitliche Vorhersage von Nitrat im Grundwasser zu erzielen und damit zur effizienten und nachhaltigen Nitrat-Reduzierung beizutragen. Diese werden mit Methoden des Operation Research und der semantischen Datenintegration erweitert, um damit einen Endnutzer bei der Entscheidungsfindung intelligent zu unterstützen.

description: We investigate the modification of the intrinsic carrier noise spectral density induced in low-doped semiconductor materials by an external correlated noise source added to the driving high-frequency periodic electric field. A Monte Carlo approach is adopted to numerically solve the transport equation by considering all the possible scattering phenomena of the hot electrons in the medium. We show that the noise spectra are strongly affected by the intensity and the correlation time of the external random electric field. Moreover this random field can cause a suppression of the total noise power.

description: Recently, IoT usage has grown rapidly. Security risks are rising analogously, though. Our paper introduces an approach to identify and address security threats by applying the PASTA (Process for Attack Simulation and Threat Analysis) threat model to the IoT domain. By adapting PASTA, we optimize the threat analysis based on domain knowledge and specific needs of IoT. With integration of the PASTA results into the development process and the IoT software development life cycle, we reduce security risks. A prototype demonstrates the feasibility of the concept for security vulnerability reduction via an integrated DevSecOps toolchain.

description: The increase in interconnected devices in electrical power systems raises the attack surface of a network and therefore the system connected within the network. Cyber-attacks can lead to power cut of an individual system or multiple systems required in the power generation stage and critical in normal operation of the plant. With the purpose to monitor and understand the impacts of cyber-attacks at the component level, system level and plant level, a testbed simulation environment for the Electrical Power Systems in a virtual power plant was modelled. This paper provides comprehensive information about the developed Simulink model for the electrical power system. The Simulink model was created to leverage freedom of customizing and testing of diverse cyber threat scenarios. The simulation model was set to communicate with physical controller to analyse the system level and plant level impacts of cyber-attacks on the physical devices.

description: Strong gravitational lensing is a unique tool to model with great accuracy the inner mass distribution of massive galaxy clusters. In particular, clusters with large Einstein radii provide a wealth of multiply imaged systems in the cluster core allowing to determine precisely the shape of the central dark matter profile. This paper presents a spectroscopic survey in the massive cluster Abell 1703, displaying a large Einstein radius (28" at z=2.8) and a high number of strongly-lensed systems including a central ring-like configuration. We used LRIS on Keck to target multiple images and lensed galaxy candidates, and use the measured redshifts to constrain the mass distribution of the cluster using a parametric model. The data enable us to measure accurate redshifts in good agreement with their photometric redshifts, and to update the identification of multiply imaged systems by discovering 3 new systems and a radial counter image. We also report the discovery of a remarkably bright ~3.6 L* i-band dropout at z=5.827 in our mask which is only moderately magnified by the cluster (~3.0+/-0.08). The improved parametric mass model, including 16 multiple systems with 10 spectroscopic redshifts, further constrains the cluster-scale mass distribution with a generalized NFW profile of best-fit logarithmic slope alpha=0.92+/-0.04, concentration c200=4.72+/-0.40 and scale radius rs=476+/-45 kpc. Our strong-lensing model predicts a large scale shear signal consistent with Subaru weak-lensing measurements out to 4 Mpc h^-1. Together with the fact that the strong-lensing modeling requires a single dark matter clump, this suggests that Abell 1703 is a relaxed, unimodal cluster. This unique cluster could be probed further using deep X-ray, SZ and dynamics analysis, for a detailed study of the physics in a relaxed cluster. (abridged)

Fine arts in Vancouver, 1886-1930 : an historical survey
Creators: name: Thom, William Wylie
Publisher: name: University of British Columbia
Year: 2012

description: Canadians in recent years have become increasingly aware of their heritage. Entering into a new era of self confidence, they have been looking with greater interest at their past and discovering things of value in this heritage. This paper looks at a part of this past and examines the events from 1886 to 1930 which formed the background, and laid the foundations for Vancouver's later development as a lively and important art centre. This period is largely undocumented, its importance to the contemporary Vancouver art scene usually forgotten. Vancouver from its inception attracted more than its share of persons with education and vision, individuals who saw what the city was to become and who were prepared to give their time and interest to the work of fostering societies and institutions of a cultural nature including the early art societies. The focus here is on these societies and on the slow but continuing growth of art activity in Vancouver, showing the important role that these early groups played in creating an art environment and keeping alive a spirit of artistic endeavour when there was little general interest in the arts in the city. Consideration has been given to the individuals - artists, critics, educators - who were key figures in the genesis and form of artistic expression during the period, as well as to the social and cultural factors which to a large extent determined the direction which the fine arts took in Vancouver in the first quarter of the twentieth century. The emphasis throughout has been on the historical development, the object being to trace the growth of art in Vancouver through the individuals and the societies they formed. Most of the material has been obtained from primary sources, principally from the newspapers of the time, but also from the records of art societies, exhibition catalogues, letters and other documents, and from interviews with individuals who were close to the period. These sources reveal a surprising amount of art activity, they also point up the importance of this activity in establishing a climate of art in Vancouver from which those who followed have gained. The major accomplishments such as the formation of an art school and the founding of an art gallery had a direct bearing on the present and a broader picture of Vancouver art should be possible when the events of the present are set against the background of their historical precedents.

description: Decision makers strive for optimal ways of production and usage of energy. To adjust their behavior to the future situation of markets and technology, the execution of different models predicting e.g. energy consumption, energy production, prices and consumer behavior is necessary. This execution is itself time-consuming and requires input data management. Furthermore, since different models cover different aspects of the energy domain, they need to be linked. To speed up the linkage and reduce manual errors, these linkage needs to be automated. We present IRPsim, an infrastructure for computation of different models and their linkage. The IRPsim-infrastructure enables management of model data in a structured database, parallelized model execution and automatic model linkage. Thereby, IRPsim allows researchers and practitioners to use energy system models for strategic business model analysis.

description: We show that images of TeV blazars in the GeV energy band should contain, along with point-like sources, degree-scale jet-like extensions. These GeV extensions are the result of electromagnetic cascades initiated by TeV gamma-rays interacting with extragalactic background light and the deflection of the cascade electrons/positrons in extragalactic magnetic fields (EGMF). Using Monte-Carlo simulations, we study the spectral and timing properties of the degree-scale extensions in simulated GeV band images of TeV blazars. We show that the brightness profile of such degree-scale extensions can be used to infer the lightcurve of the primary TeV gamma-ray source over the past 1e7 yr, i.e. over a time scale comparable to the life-time of the parent active galactic nucleus. This implies that the degree-scale jet-like GeV emission could be detected not only near known active TeV blazars, but also from "TeV blazar remnants", whose central engines were switched off up to ten million years ago. Since the brightness profile of the GeV "jets" depends on the strength and the structure of the EGMF, their observation provides additionally information about the EGMF.

description: The Bavarian higher education environment is aiming to renew its IT strategy. The overall objective is to find an organisational solution which allows both local independence and collaborative solutions in those areas which are either commodities or which are too complex or costly to be solved several times in parallel. All Bavarian CIOs are engaged in the development of a model which respects local governance to be included into the overarching IT strategy of Bavaria, potentially Germany and Europe. As a common framework, COBIT was chosen to structure the process and guarantee completeness. The application of COBIT was started by the agreement to a common model. Further, the description of the respective responsibilities and competencies for all stakeholders was defined. We share this current state of the discussion with the broader community of higher education to promote further discussions about methods and objectives.

description: The type used to print an early modern book can give scholars valuable information about the time and place of its production as well as its producer. Recognizing such type is currently done manually using both the character shapes of 'M' or 'Qu' and the size of the total type to look it up in a large reference work. This is a reliable method, but it is also slow and requires specific skills. We investigate the performance of type classification and type retrieval using a newly created dataset consisting of easy and difficult types used in early printed books. For type classification, we rely on a deep Convolutional Neural Network (CNN) originally used for font-group classification while we use a common writer identification method for the retrieval case. We show that in both scenarios, easy types can be classified/retrieved with a high accuracy while difficult cases are indeed difficult.
On topological semigroups with invariant means in the convex hull of multiplicative means
Creators: name: Lau, Anthony To-Ming
Publisher: name: University of British Columbia
Year: 2011

description: Let S be a topological semigroup and C(S) the space of bounded real continuous function on S with sup norm. For f є C(S), s, t є S, [subscript s]f(t) = f(st), let LUC(S) be the space of all f є C(S) for which the map s ↦ [subscript s] f from S to C(S) is continuous, Δ(S) the set of multiplicative means on LUC(S), and CoΔ(S) the convex hull of Δ(S). In this thesis we study and characterize topological semigroup S for which (*) LUC(S) has a LIM (left invariant mean) in CoΔ(S). A decomposition theorem for such semigroups has been obtained. We also consider properties that arise from the action of semigroups satisfying (*) on certain topological spaces. In particular, we generalise Mitchell's fixed point theorem (theorem 1 [28]). Other characterization theorems and combinatorial properties for such semigroups have also been obtained. Continuing the work of J. Sorenson [32], we obtain characterizations and functional analytic properties for discrete semigroups satisfying (*), generalising some of the results of Granirer [12], [13], [l14] and Mitchell [26] for semigroups admitting a multiplicative LIM. Finally we characterize all semigroups S for which m(S) (the space of hounded real functions) has a non-trivial translation invariant subalgebra, containing constants and admits a multiplicative LIM. We also give a method, utilizing the class of left thick subsets of Mitchell [25], in constructing a huge class of such subalgebras. Furthermore, we show that the above method and characterization is valid even for semigroup of transformations. Other diverse results in this direction are also obtained.

description: The ability to anticipate future changes in terrestrial ecosystems is key for their management. New tools are required that bridge the gap between a high level of process understanding at fine spatial grain, and the increasing relevance for management at larger extents. Such a tool is SVD (Scaling Vegetation Dynamics), a scaling framework that specifically uses deep learning to learn the behavior of detailed vegetation models in response to different environmental factors. This trained deep neural network (DNN) is then applied within the framework on large spatial scales. In addition, SVD includes also explicitly modelled processes such as fire disturbances. Here we use the framework to simulate forest regime change in the 3 Mio. ha landscape of the Greater Yellowstone Ecosystem. We used four climate change scenarios and pre-defined fire events from statistical modelling, and analyzed whether prevailing forest types are able to regenerate after fire. Our results show that up to 60% of the area may undergo regime change until the end of the 21st century.

description: We present an alternative technique for measuring the precursor masses of transient events in stars undergoing late stage stellar evolution. We use the well-established techniques of stellar population modeling to age-date the stars surrounding the site of the recent transient event in NGC 300 (NGC 300 OT2008-1). The surrounding stars must share a common turnoff mass with the transient, since almost all stars form in stellar clusters that remain physically associated for periods longer than the lifetime of the most massive stars. We find that the precursor of NGC 300 OT2008-1 is surrounded by stars that formed in a single burst between 8-13 Myr ago, with 70% confidence. The transient was therefore likely to be due to a progenitor whose mass falls between the main sequence turnoff mass (12 Msun) and the maximum stellar mass (25 Msun) found for isochrones bounding this age range. We characterize the general applicability of this technique in identifying precursor masses of historic and future transients and supernovae (SNe), noting that it requires neither precursor imaging nor sub-arcsecond accuracy in the position of the transient. It is also based on the well-understood physics of the main sequence, and thus may be a more reliable source of precursor masses than fitting evolutionary tracks to precursor magnitudes. We speculate that if the progenitor mass is close to 17 Msun, there may be a connection between optical transients such as NGC 300 OT2008-1 and the missing type II-P SNe, known as the "red supergiant problem."

description: Knowledge graphs as fundamental pillar of artificial intelligence are experiencing a strong demand. In contrast to machine learning and deep learning, knowledge graphs do not require large amounts of (training) data and offer a bigger potential for a multitude of domains and problems. This article shows the application of knowledge graphs for the semantic description and management of data in a data lake, which improves the findability and reusability of data, and enables the automatic processing by algorithms. Since knowledge graphs contain both the data as well as its semantically described schema (ontology), they enable novel ontology-driven software architectures, in which the domain knowledge and business logic can completely reside on the knowledge graph level. This article further introduces such a use case: an ontology-driven frontend implementation, which is able to fully adapt itself based on the underlying knowledge graph schema and dynamically render information in the desired manner.

description: We study cosmologies in modified theories of gravity considering Lagrangian density $f(R)$ which is a polynomial function of scalar curvature ($R$) in the Einstein-Hilbert action in vacuum. The field equation obtained from the modified action corresponding to a Robertson-Walker metric is highly non-linear and not simple enough to obtain analytic solution. Consequently we adopt a numerical technique to study the evolution of the FRW universe. A number of evolutionary phases of the universe including the present accelerating phase are found to exist in the higher derivative theories of gravity. The cosmological solutions obtained here are new and interesting. We study modified theory of gravity as a toy model to explore the past, the present and predict the future evolution. It is found that all the models analyzed here can reproduce the current accelerating phase of expansion of the universe. The duration of the present accelerating phase is found to depend on the coupling constants of the gravitational action. The physical importance of the coupling parameters those considered in the action are also discussed.

description: We analyze the Mass Varying Neutrino (MaVaN) scenario. We consider a minimal model of massless Dirac fermions coupled to a scalar field, mainly in the framework of finite temperature quantum field theory. We demonstrate that the mass equation we find has non-trivial solutions only for special classes of potentials, and only within certain temperature intervals. We give most of our results for the Ratra-Peebles Dark Energy (DE) potential. The thermal (temporal) evolution of the model is analyzed. Following the time arrow, the stable, metastable and unstable phases are predicted. The model predicts that the present Universe is below its critical temperature and accelerates. At the critical point the Universe undergoes a first-order phase transition from the (meta)stable oscillatory regime to the unstable rolling regime of the DE field. This conclusion agrees with the original idea of quintessence as a force making the Universe roll towards its true vacuum with zero Λ-term. The present MaVaN scenario is free from the coincidence problem, since both the DE density and the neutrino mass are determined by the scale M of the potential. Choosing M ~ 10^{-3} eV to match the present DE density, we can obtain the present neutrino mass in the range m ~ 10^{-2}-1 eV and consistent estimates for other parameters of the Universe.

description: We study the dynamics of a timelike vector field which violates Lorentz invariance when the background spacetime is in an accelerating phase in the early universe. It is shown that a timelike vector field is difficult to realize an inflationary phase, so we investigate the evolution of a vector field within a scalar field driven inflation model. And we calculate the power spectrum of the vector field without considering the metric perturbations. While the time component of the vector field perturbations provides a scale invariant spectrum when $ξ= 0$, where $ξ$ is a nonminimal coupling parameter, both the longitudinal and transverse perturbations give a scale invariant spectrum when $ξ= 1/6$.

description: We investigate inflation driven by $N$ dynamical five-branes in Heterotic M-theory using the scalar potential derived from the open membrane instanton sector. At leading order the resulting theory can be mapped to power law inflation, however more generally one may expect higher order corrections to be important. We consider a simple class of such corrections, which imposes tight bounds on the number of branes required for inflation.

description: Gas bubble growth as a result of diffusion flux of dissolved gas molecules from the surrounding supersaturated solution to the bubble surface is studied. The condition of the flux steadiness is revealed. A limitation from below on the bubble radius is considered. Its fulfillment guarantees the smallness of fluctuation influence on bubble growth and irreversibility of this process. Under the conditions of steadiness of diffusion flux three stages of bubble growth are marked out. With account for Laplace forces in the bubble intervals of bubble size change and time intervals of these stages are found. The trend of the third stage towards the self-similar regime of the bubble growth, when Laplace forces in the bubble are completely neglected, is described analytically.
