Using secondary internet research, a database of key e-mobility supply factors was generated and visualized utilizing a geographical information system. The results show that fragmentation in infrastructure and information due to the cross-border situation of the four-country region is the main obstacle for e-mobility in tourism in the Lake Constance region. Cooperation and coordination of the supply side of e-mobility in the Lake Constance region turned out to be weak. To improve the chances of e-mobility in cross-border tourism a more client-oriented approach regarding information, accessibility, and conditions of use is necessary.

Zu diesem Zweck werden Stil- und Kompositionsmittel aus den Bereichen Lexik, Grammatik, Syntax, Stilistik, Erzählstrategie und Textorganisation anhand von Formulierungsbeispielen vorgestellt und auf ihre Funktion in Erzählliteratur oder Journalismus hin untersucht. In einem zweiten Schritt wird jeweils nach der Übertragbarkeit dieser sprachlichen Mittel auf Fachtexte gefragt. Anhand parallel ausgerichteter Beispiele wird eine mögliche verlagerte Funktion im Wissenschaftskontext skizziert. Der erhoffte Erkenntnisgewinn des Vortrags betrifft sowohl das Verfassen eigener Publikationen als auch die Vermittlung von Schreibfähigkeiten für künftige Fachautor*innen, weshalb die Formulierungsbeispiele verschiedensten, auch technischen und naturwissenschaftlichen Domänen entnommen sind.

However, performances on authentic and complex tasks are often difficult to score, because they involve not only specific language ability but also field specific knowledge. Moreover, the emphasis of tasks on meaning suggests that the communicative outcome should be regarded as the main criterion of success. This paper focuses on task design and scoring. It is argued that tasks have to be adapted to assessment purposes. However, to avoid a misalignment between teaching/learning and assessment, they should comprise the main features of LSP tasks in the sense of task-based language learning.

Thereby, they can implement Shadow IT (SIT) without involving a central IT department to create flexible and innovative solutions. Self-reinforcing effects lead to an intertwinement of SIT with the organization. As a result, high complexities, redundancies, and sometimes even lock-ins occur. IT Integration suggests itself to meet these challenges. However, it can also eliminate the benefits that SIT presents. To help organizations in this area of conflict, we are conducting a literature review including a systematic search and an analysis from a systemic viewpoint using path dependency and switching costs. Our resulting conceptual framework for SIT integration drawbacks classifies the drawbacks into three dimensions. The first dimension consists of switching costs that account for the financial, procedural, and emotional drawbacks and the drawbacks from a loss of SIT benefits. The second dimension includes organizational, technical, and level-spanning criteria. The third dimension classifies the drawbacks into the global level, the local level, and the interaction between them. We contribute to the scientific discussion by introducing a systemic viewpoint to the research on shadow IT. Practitioners can use the presented criteria to collect evidence to reach an IT integration decision.

Thereby, they implement Shadow IT (SIT) to create flexible and innovative solutions. However, the individual implementation of SIT leads to high complexities and redundancies. Integration suggests itself to meet these challenges but can also eliminate the described benefits. In this emergent research, we develop propositions for a conceptual decision framework, that balances the benefits and drawbacks of an integration of SIT using a literature review as well as a multiple-case study. We thereby integrate the perspective of the overall organization as well as the specific business unit. We then pose six propositions regarding SIT integration that will serve to evaluate our conceptual framework in future research.

In developing countries such as Ethiopia, potatoes have not been dried, but are traditionally stored in potato clamps. So far, dried potatoes have not been converted into usable foods. The aim of the present work is to convert potatoes - perishable rootlets and tubers - into stable products by hot air drying. Hot air dryers are economical to operate in industrialized countries. In Africa, this is reserved for larger industrial companies only. In regions with a tropical climate, however, the use of solar tunnel dryers is worthwhile. These are a good choice for farming and small industries and wherever electrical energy is difficult or impossible to obtain. In a first part of the work, the drying process of potatoes was investigated, in particular with regard to the change of thermal, mechanical and chemical quality parameters. In an evaluation of the literature it was found that potatoes are not subject to quality changes if the water activityis below a value of 0.2. In order to determine the water content associated with this value at storage temperature, the known equations for the sorption equilibrium were evaluated and verified with own experimental investigations. This determined the end point of the drying process. The following experimental investigations showed a process-dependent change of the quality criteria such as color, shrinkage, and mechanical properties as well as the content of valuedetermining substances such as vitamin C and starch. The differences in the course and magnitude of the quality changes were attributed to the glass transition that takes place during the drying process. For the determination of the glass transition temperature a new, simple method based on the measurement of mechanical properties could be developed. The knowledge of the glass transition temperature allowed optimizing the drying process. The drying process could be carried out in the rubbery or glassy region, depending on the expected quality changes. Thus, all information was available to produce high quality dried potatoes in an industrial process. Since the production of potato products in less industrialized regions without sufficient supply of electrical energy should be included, potatoes were dried with a solar tunnel dryer. Examination of the quality properties mentioned above confirmed the process-dependent quality changes. Finally, the dried product was ground and with the flour thus produced, wheat flour was replaced for baking bread. An evaluation of the finished bread by a panel showed that the acceptance of the bread according to the new recipe was high, also with regard to baking volume, taste, texture and color. This work shows that by drying potatoes can be transformed a well accepted, storable and easily transportable product. The risk of losses or degradation is minimized. It can be produced on an industrial as well as on farm level. If the influence of the glass transition is taken into account, it is possible to optimize the quality of the product.

The influence of stress results in a higher rate of health disorders such as burnout, heart problems, obesity, asthma, diabetes, depressions and many others. Furthermore individual’s behavior and capabilities could be directly affected leading to altered cognition, inappropriate decision making and problem solving skills. In a dynamic and unpredictable environment, such as automotive, this can result in a higher risk for accidents. Different papers faced the estimation as well as prediction of drivers’ stress level during driving. Another important question is not only the stress level of the driver himself, but also the influence on and of a group of other drivers in the near area. This paper proposes a system, which determines a group of drivers in a near area as clusters and it derives the individual stress level.

Aggregated data can be used to generate navigation routes with a lower stress influence to decrease stress influenced driving as well as improve road safety.

The average sleep duration for an adult is approximately 7 h per day. Sleep is necessary to regenerate physical and psychological state of a human. A bad sleep quality has a major impact on the health status and can lead to different diseases. In this paper an approach will be presented, which uses a long-term monitoring of vital data gathered by a body sensor during the day and the night supported by mobile application connected to an analyzing system, to estimate sleep quality of its user as well as give recommendations to improve it in real-time. Actimetry and historical data will be used to improve the individual recommendations, based on common techniques used in the area of machine learning and big data analysis.

Up to now so called hard switching topologies have been used. A new 'Soft Switching Three Level Inverter (S3L Inverter)' which is now available provides reduced switching losses and higher efficiency. In this paper the S3L inverter is compared with a hard switching T-type inverter topology (H3L inverter). S3L inverters provide higher efficiency and additionally advantages in electromagnetic compatibility due to the soft switching performance, especially when using the 'Super Soft Switching Three Level Inverter (SS3L Inverter)'.

A cascaded structure of nonlinear filters is proposed that contains several parallel branches, consisting of polynomial functions followed by a linear filter for each order of nonlinearity. The second order of nonlinearity is additionally modelled with a parallel branch, containing a Volterra filter. These are followed by a long linear FIR filter that is able to model the room acoustics. The model is applied to the identification of a tube power amplifier feeding a guitar loudspeaker cabinet in an acoustic room. The adaptive identification is performed by the normalized least mean square (NLMS) algorithm. Compared with a generalized polynomial Hammerstein (GPH) model, the accuracy in modelling the dedicated real world system can be improved to a greater extend than increasing the order of nonlinearity in the GPH model.

Most commonly, the speech component in a selected reference microphone is estimated. The choice of this reference microphone influences the broadband output signal-to-noise ratio (SNR) as well as the speech distortion. Recently, a generalized formulation for the MWF (G-MWF) was proposed that uses a weighted sum of the individual transfer functions from the speaker to the microphones to form a better speech reference resulting in an improved broadband output SNR. For the MWF, the influence of the phase reference is often neglected, because it has no impact on the narrow-band output SNR. The G-MWF allows an arbitrary choice of the phase reference especially in the context of spatially distributed microphones. In this work, we demonstrate that the phase reference determines the overall transfer function and hence has an impact on both the speech distortion and the broadband output SNR. We propose two speech references that achieve a better signal-to-reverberation ratio (SRR) and an improvement in the broadband output SNR. Both proposed references are based on the phase of a delay-and-sum beamformer. Hence, the time-difference-of-arrival (TDOA) of the speech source is required to align the signals. The different techniques are compared in terms of SRR and SNR performance.

Vorstände, Geschäftsführer, Aufsichtsräte und obere Führungskräfte – mit den wesentlichen Grundlagen, theoretischen Zusammenhängen und anwendungsbezogenen Konzepten zum Thema Unternehmensintegrität vertraut zu machen. Es scheint eine zwingende Voraussetzung für das Gelingen einer verantwortungsvollen Unternehmensführung zu sein, dass sich die Unternehmenslenker systematisch mit der moralischen Seite des Wirtschaftens befassen, um Rechts- und Reputationsrisiken präventiv begegnen und Chancen aus vertrauensvollen Kooperationsbeziehungen mit den Stakeholdern des Unternehmens nachhaltig nutzen zu können. Viele negative Beispiele aus den letzten Jahren im Bereich der unternehmensbezogenen Korruption, der Geldwäsche, der Wettbewerbsdelikte, der Verstöße gegen das Umweltrecht etc. haben gezeigt, dass vorhandene Compliance-Systeme systematisches Fehlverhalten in bzw. von Unternehmen nicht verhindern oder frühzeitig aufdecken konnten. Der „VW-Abgasskandal“ steht sinnbildlich für dieses „Compliance-Versagen“. Häufig liegt die Ursache dafür in der mangelnden Ernsthaftigkeit und Glaubwürdigkeit der unternehmensbezogenen Redlichkeitsbemühungen. Die FCI-Handreichung möchte daher erstens einen Diskussionsbeitrag dazu leisten, wie durch Maßnahmen des „Integrity Managements“ die herkömmlichen Compliance-Systeme in ihrer Wirksamkeit verbessert werden können. Dabei ist klar, dass diese Ausführungen keine letzten Wahrheiten darstellen, sondern das ernsthafte Bemühen um bessere Lösungen fördern sollen. Eine zweite weiterführende Zielsetzung ist die Förderung der Reflexion der über die rechtlich normierten Standards hinausgehenden Unternehmensverantwortung (Corporate Responsibility). Eine so gelagerte werteorientierte Unternehmensführung erkennt die für das eigene Unternehmen kritischen moralischen Fragen, setzt Maßstäbe für das eigene Handeln und zeigt dabei sowohl den eigenen Gestaltungsanspruch als auch die Grenzen der (möglichen) Verantwortungsübernahme klar und selbstbewusst auf. Die konzeptionellen Ausführungen richten sich ebenso wie die enthaltenen Handlungsempfehlungen in Form von Dos und Don‘ts an Manager, die von sich aus davon überzeugt sind, dass nachhaltiger Erfolg durch eine integre Unternehmensführung unterstützt wird. Damit ist gleichzeitig gesagt, dass es auch nicht-integre Unternehmen gibt, die viel Geld verdienen und die Handreichung keinerlei missionarische Absichten hegt. Manager und Unternehmen sollen angesprochen werden, die sich dem Leitbild des „ehrbaren Kaufmanns“ längst verschrieben haben und nach Anregungen und Vorschlägen suchen, wie dieses Leitbild umgesetzt werden kann. Eines ist dabei zugleich klar: auch Manager und Unternehmen, die sich ernsthaft bemühen, verantwortungsvoll und integer zu führen und zu handeln, können im Einzelfall scheitern. Dass es zu keinem „systemischen Fehlverhalten“ in diesen Organisationen kommt, dazu möchte die Handreichung des FCI beitragen.

T1 - Radiometric calibration of digital cameras using sparse Gaussian processes T2 - 22. Workshop Farbbildverarbeitung : 29.-30. September 2016, Ilmenau N2 - Digital cameras are used in a large variety of scientific and industrial applications. For most applications the acquired data should represent the real light intensity per pixel as accurately as possible. However, digital cameras are subject to different sources of noise which distort the resulting image. Noise includes photon noise, fixed pattern noise and read noise. The aim of the radiometric calibration is to improve the quality of the resulting images by reducing the influence of the different types of noise on the measured data. In this paper, a new approach for the radiometric calibration of digital cameras using sparse Gaussian process regression is presented. Gaussian process regression is a kernel based supervised machine learning technique. It is used to learn the response of a camera system from a set of training images to allow for the calibration of new images.

The surface quality includes the topography of the surface, the structure and composition of the passive layer, and the surface near structure of the base material. These factors are influenced by final physical/chemical surface treatments. The presented work shows significantly lower corrosion resistance for mechanical machined specimens than for etched specimens. It also turns out that the rougher the surface, the lower the corrosion resistance gets. However, there is no general finding which shows if blasted or grinded surfaces are more appropriate, but a dependency on process parameters and the characteristics on corrosive exposure in terms of corrosion behavior. The results show that not only the surface roughness Ra has an influence on corrosion behavior but also the shape of peaks and valleys which are evolved by surface treatments. Imperfections in the base material, like sulfidic inclusions lead to a weaker passive layer, respectively, to a decrease of the corrosion resistance. By using special passivating techniques the corrosion resistance of stainless steels can be increased to a higher level in comparison to common passivation.

We present a static analysis tool using abstract bytecode interpretation that checks Java classes for compliance with a set of rules that together constitute state-based immutability. Being realized as a Find Bugs plug in, the tool can easily be integrated into most IDEs and hence the software development process. Our evaluation on a large, real world codebase shows that the average run-time effort for a single class is in the range of a few milliseconds, with only a very few statistical spikes.

Besides these formal systems, there are additional systems that are rather stand-alone and not included in the IT management tasks. These so-called ‘shadow systems’ also support business processes but hinder a high enterprise integration. Shadow systems appear during their explicit detection or during software maintenance projects such as enhancements or release changes of enterprise systems. Organizations then have to decide if and to what extent they integrate the identified shadow systems into their ERP systems. For this decision, organizations have to compare the capabilities of each identified shadow system with their ERP systems. Based on multiple-case studies, we provide a dependency approach to enable their comparison. We derive categories for different stages of the dependency and base insights into integration possibilities on these stages. Our results show that 64% of the shadow systems in our case studies are related to ERP systems. This means that they share parts or all of their data and/or functionality with the ERP system. Our research contributes to the field of integration as well as to the discussion about shadow systems.

Decreasing stiffness can be detected be repeatedly measurements. Damaged parts of the construction or too high wood moisture can be reasons for decreasing stiffness. The earlier the failure is detected the better is the chance to repair it with low costs. The method of monitoring by repeatedly measuring the natural frequency is applied at timber bridges, especially on footbridges. As damages due to high wood moisture cannot be seen easily, measuring the natural frequency is a good possibility to detect them and then to repair them. Equations to calculate the natural frequencies regarding the damaged parts are shown and applied to a simple supported beam.

Agreement on the evaluations of venturing projects based on the business plans highly depends on the individual perspective of the readers [5], [6]. One reason is that little empirical proof exists for descriptions in business plans that suggest survival of early-stage technology ventures [7]–[9]. We identified descriptions of transaction relations [10]–[13] as an anchor of the snapshot model business plan to business reality [13]. In the early-stage, surviving ventures are building transaction relations to human resources, financial resources, and suppliers on the input side, and customers on the output side of the business towards a stronger ego-centric value network [10]–[13]. We conceptualized a multidimensional measurement instrument that evaluates the maturity of this ego-centric value networks based on the transaction relations of different strength levels that are described in business plans of early-stage technology ventures [13]. In this paper, the research design and the instrument are purified to achieve high agreement in the evaluation of business plans [14]–[16]. As a result, we present an overall research design that can reach acceptable quality for quantitative research. The paper so contributes to the literature on business analysis in the early-stage of technology-based ventures and the research technique of content analysis.

Jahrestagung des Fachverbandes Deutsch als Fremd- und Zweitsprache an der Universität Münster 2014 N2 - Der von Ehlich eingeführte Begriff „alltägliche Wissenschaftssprache“ hat die Diskussion um die Sprachvermittlung für den Sprachgebrauch im Studium maßgeblich geprägt. Auch die Abkürzung „AWS“ ist mittlerweile recht verbreitet. Gemeint sind sprachliche Elemente, die neben der Fachterminologie in unterschiedlichen Disziplinen weitgehend ähnlich sind. Man geht davon aus, dass diese Elemente in mehreren Disziplinen verwendet werden. Mit dieser Argumentation lässt sich eine disziplinübergreifende Sprachvermittlung begründen. In diesem Beitrag wird das AWS-Konzept einer neuerlichen Betrachtung unterzogen. Dazu werden folgende Fragen formuliert: 1. Ist ein disziplinübergreifender Ansatz für die Kursorganisation hilfreich? Das AWS-Konzept bezieht seine Attraktivität auch aus dem praktischen Nutzen für die Planung von Sprachkursen, denn es ist häufig schwierig, gesonderte Sprachkurse für verschiedene Disziplinen anzubieten. 2. Ist das Konzept der AWS aus linguistischer Sicht zutreffend? Zur Frage, wie unterschiedlich die sprachlichen Anforderungen der einzelnen wissenschaftlichen Disziplinen sind, gibt es in der Literatur divergierende Auffassungen. Einige Forschungsansätze und Ergebnisse werden in diesem Beitrag skizziert. 3. Überzeugt das Konzept der AWS als Grundlage für Vermittlungsprozesse? Ein Blick auf Lehrmaterialien verdeutlicht, wie Wissenschaftssprache disziplinübergreifend vermittelt werden kann und welche Probleme sich ergeben. Die hier vorgestellten Überlegungen münden letztlich in den Appell, die unterschiedlichen sprachlichen Anforderungen in den verschiedenen Fächern nach Möglichkeit zu berücksichtigen.

Analysing the decision element is essential for studying the scale of sentence severity for cross-jurisdictional comparisons. Examining the intent element can facilitate future risk assessment. Analysing the fact element can enhance an organization's capability of analysing criminal activities for future offender profiling. Examining the evidence used against a defendant from previous judgements can facilitate the preparation of evidence for upcoming legal disclosure. Follow the concepts of argumentation diagrams, we develop an automatic judgement summarizing system to enhance the accessibility of judgements and avoid repeating past mistakes. Inspired by the feasibility of extracting legal knowledge for argument construction and employing grounds of inadmissibility for probability assessment, we conduct evidential reasoning of kernel traces for forensic readiness. We integrate the narrative methods from attack graphs/languages for preventing confirmation bias, the argumentative methods from argumentation diagrams for constructing legal arguments, and the probabilistic methods from Bayesian networks for comparing hypotheses.

For this purpose we use the (min,×)stochastic network calculus as well as a recently presented recursive formula for an end-to-end delay bound of wireless heterogeneous networks. The derived results are mapped to WirelessHART networks used in process automation and were validated via simulations. In addition to WirelessHART, our results can be applied to any wireless network whose physical layer conforms the IEEE 802.15.4 standard, while its MAC protocol incorporates TDMA and channel hopping, like e.g. ISA100.11a or TSCH-based networks. The provided delay analysis is especially useful during the network design phase, offering further research potential towards optimal routing and power management in QoS-constrained wireless industrial networks.

In addition to that, the stress algorithm compares whether the current heartbeat is similar or different to the last heartbeat after detecting the ECG signals. This algorithm determines the stress detection for the patient on the real-time. In order to implement the new algorithm with higher performance, the parallel programming language CUDA is used.

The majority of models of spectrum usage are not suitable for this specific use case as they are based on measurement campaigns conducted in urban or controlled laboratory environments. In this work we present a time-domain traffic model for industrial communication in the 2.4 GHz industrial, scientific, medical (ISM) band based on measurements in an industrial automotive production site. As DSA is usually implemented on Software Defined Radios (SDR), our measurement campaign is based on SDR platforms rather than sophisticated spectrum analyzers. We show through the estimation of the Hurst parameter that industrial wireless traffic possesses inherent self-similarity that could be exploited for efficient DSA. We also show that wireless traffic could be modeled as a semi-Markov model with channel on and off durations Log-normally and Pareto distributed, respectively. We finally estimate the parameters of the derived models using Maximum Likelihood estimation.

The cornerstone of CR is spectrum occupancy prediction that enables agile and proactive spectrum access and efficient utilization of spectral resources. Hidden Markov Models (HMM) provide powerful and flexible tools for statistical spectrum prediction. In this paper we introduce a HMM-based spectrum prediction algorithm for industrial applications that accurately predicts multiple slots in the future. Traditional HMM prediction approaches use two hidden states enabling the prediction of only one step ahead in the future. This one step is most often not enough due to internal hardware delays that render it outdated. We show in this work that extending the number of hidden states and formulating the prediction problem as a maximum likelihood (ML) classification approach enables a prediction span of multiple slots in the future even with fine spectrum sensing resolution. We verify the suitability of our approach to industrial wireless through extensive simulations that utilize a realistic measurement-based traffic model specifically tailored for industrial automotive settings.

T1 - Increasing robustness of handwriting recognition using character N-Gram decoding on large lexica T2 - 12th IAPR Workshop on Document Analysis Systems (DAS), 11-14 April 2016 N2 - Offline handwriting recognition systems often include a decoding step, that is retrieving the most likely character sequence from the underlying machine learning algorithm. Decoding is sensitive to ranges of weakly predicted characters, caused e.g. by obstructions in the scanned document. We present a new algorithm for robust decoding of handwriting recognizer outputs using character n-grams. Multidimensional hierarchical subsampling artificial neural networks with Long-Short-Term-Memory cells have been successfully applied to offline handwriting recognition. Output activations from such networks, trained with Connectionist Temporal Classification, can be decoded with several different algorithms in order to retrieve the most likely literal string that it represents. We present a new algorithm for decoding the network output while restricting the possible strings to a large lexicon. The index used for this work is an n-gram index with tri-grams used for experimental comparisons. N-grams are extracted from the network output using a backtracking algorithm and each n-gram assigned a mean probability. The decoding result is obtained by intersecting the n-gram hit lists while calculating the total probability for each matched lexicon entry. We conclude with an experimental comparison of different decoding algorithms on a large lexicon.

The first category do not require any special equipment for measuring the stress. This category useless the variation in the behaviour patterns that occur while stress. The core disadvantage for the category is their limitation to specific use case. The second category uses laboratories instruments and biological sensors. This category allow to measure stress precisely and proficiently but on the same time they are not mobile and transportable and do not support real-time feedback. This work presents a mobile system that provides the calculation of stress. For achieving this, the of a mobile ECG sensor is analysed, processed and visualised over a mobile system like a smartphone. This work also explains the used stress measurement algorithm. The result of this work is a portable system that can be used with a mobile system like a smartphone as visual interface for reporting the current stress level.
