AB - Infrastructure as a Service providers use virtualization to abstract their hardware and to create a dynamic data center. Virtualization enables the consolidation of virtual machines as well as the migration of them to other hosts during runtime. Each provider has its own strategy to efficiently operate a data center. We present a rule based mapping algorithm for VMs, which is able to automatically adapt the mapping between VMs and physical hosts. It offers an interface where policies can be defined and combined in a generic way. The algorithm performs the initial mapping at request time as well as a remapping during runtime. It deals with policy and infrastructure changes. We extended the open source IaaS solution Eucalyptus and we evaluated it with typical policies: maximizing the compute performance and VM locality to achieve a high performance and minimizing energy consumption. The evaluation was done on state-of-the-art servers in our own data center and by simulations using a workload of the Parallel Workload Archive. The results show that our algorithm performs well in dynamic data centers environments.

AB - System virtualization has become the enabling technology to manage the increasing number of different applications inside data centers. The abstraction from the underlying hardware and the provision of multiple virtual machines (VM) on a single physical server have led to a consolidation and more efficient usage of physical servers. The abstraction from the hardware also eases the provision of applications on different data centers, as applied in several cloud computing environments. In this case, the application need not adapt to the environment of the cloud computing provider, but can travel around with its own VM image, including its own operating system and libraries. System virtualization and cloud computing could also be very attractive in the context of high‐performance computing (HPC). Today, HPC centers have to cope with both, the management of the infrastructure and also the applications. Virtualization technology would enable these centers to focus on the infrastructure, while the users, collaborating inside their virtual organizations (VOs), would be able to provide the software. Nevertheless, there seems to be a contradiction between HPC and cloud computing, as there are very few successful approaches to virtualize HPC centers. This work discusses the underlying reasons, including the management and performance, and presents solutions to overcome the contradiction, including a set of new libraries. The viability of the presented approach is shown based on evaluating a selected parallel, scientific application in a virtualized HPC environment.

AB - We present a multi-agent system on top of the IaaS layer consisting of a scheduler agent and multiple worker agents. Each job is controlled by an autonomous worker agent, which is equipped with application specific knowledge (e.g., performance functions) allowing it to estimate the type and number of necessary resources. During runtime, the worker agent monitors the job and adapts its resources to ensure the specified quality of service - even in noisy clouds where the job instances are influenced by other jobs. All worker agents interact with the scheduler agent, which takes care of limited resources and does a cost-aware scheduling by assigning jobs to times with low energy costs. The whole architecture is self-optimizing and able to use public or private clouds.

AB - In dieser Arbeit stellen wir ein flexibles System zur Entwicklung und Evaluation von 3-D-Renderingalgorithmen vor, das die Visualisierung komplexer virtueller Szenen auf einem breiten Spektrum an Geräten erlaubt. Die Aufbereitung und Echtzeitdarstellung solcher virtueller Szenen, wie sie beispielsweise aus detaillierten CAD-Daten erzeugt werden, stellt in vielerlei Hinsicht eine algorithmische und technische Herausforderung dar. Die 3-D-Szenendaten können nach dem Dateiimport aus einem Austauschformat in eine Vielzahl unterschiedlicher Datenstrukturen überführt werden. Es muss ein geeignetes Renderingverfahren ausgewählt und eingestellt werden, welches sowohl die Eigenschaften der Szene (Zahl der Polygone, Grad der Verdeckung etc.) als auch die Fähigkeiten der Hardware berücksichtigt. Auf der einen Seite stellt die Darstellung auf mobilen Endgeräten wie Smartphones besonders hohe Anforderungen aufgrund der Speicherbeschränkung und der geringen Leistungsfähigkeit der Grafikhardware. Auf der anderen Seite stehen bei Großprojektionssystemen, wie beispielsweise dem HD-Visualisierungscenter des Heinz Nixdorf Instituts, die hohe Bildqualität bei stereoskopischer Darstellung und die Unterstützung von Trackingsystemen im Vordergrund.
Der Fokus des von uns entwickelten Systems PADrend liegt in der Bereitstellung einer flexiblen und leicht erweiterbaren Grundlage für die Entwicklung und Evaluation von 3-D-Renderingalgorithmen und räumlichen Datenstrukturen im Bereich der Forschung und der universitären Ausbildung. Durch den modularen Aufbau und die große Bandbreite an unterstützten Systemen wird gewährleistet, dass eine Vielzahl unterschiedlicher Entwicklungen und Anwendungen auf PADrend aufsetzen können. In diesem Artikel geben wir einen Überblick über den Aufbau und die Fähigkeiten des Systems. Des Weiteren geben wir ein Beispiel für ein Anwendungsszenario, in dem PADrend eingesetzt wird: die Visualisierung von architektonischen Modellen auf einem Multiprojektionssystem.

AB - The challenging scientific field of self-reconfiguring modular robotics (i.e., decentrally controlled 'super-robots' based on autonomous, interacting robot modules with variable morphologies) calls for novel paradigms of designing robot controllers. One option is the approach of evolutionary robotics. In this approach, the challenge is to achieve high evaluation numbers with the available resources which may even affect the feasibility of this approach. Simulations are usually applied at least in a preliminary stage of research to support controller design. However, even simulations are computationally expensive which gets even more burdensome once comprehensive studies and comparisons between different controller designs and approaches have to be done. Hence, a benchmark with low computational cost is needed that still contains the typical challenges of decentral control, is comparable, and easily manageable. We propose such a benchmark and report an empirical study of its characteristics including the transition from the single-robot setting to the multi-robot setting, typical local optima, and properties of adaptive walks through the fitness landscape.

AB - The current definitions of emergence have no effects in the context of artificial life that could convincingly be called `constructive'. They are rather descriptive labels or tests. In order to get towards recipes of generating emergence we need to know systemic characteristics that help during the design phase of artificial life systems and worlds. In this paper, we develop and discuss five hypotheses that are not meant to be irrevocable but rather thought-provoking. We introduce two modeling approaches for Langton's ant to clarify these hypotheses. Then we discuss general properties of systems, such as (ir-)reversibility, dependence on initial states, computation, discreetness, and undecidable properties of system states.

AB - This dissertation explores learner beliefs about pronunciation and their interaction with identity negotiations in a study-abroad context. Current research on studying abroad has experienced a wave of interest in learner-centered questions, gradually moving away from the narrow focus on students’ linguistic development. In particular, the effects of study abroad on learner identities have attracted attention, revealing the impact of the dispositions of individuals, as well as of interlocutors, on the language learning process. The realm of speaking, especially with regard to pronunciation research, however, has hardly benefited from this interest in the individual perspectives of sojourners. Existing studies merely measure the extent to which learners appropriate native-like accents, resulting in partly inconsistent findings with limited insight into individual learning processes and factors. I thus adopt a different focus by qualitatively investigating the interplay between sojourners’ beliefs about pronunciation and their identity constructions and negotiations. My research is based on five case studies of Canadian learners of German. Each research subject has attended a German university for one or two semesters. In applying narrative inquiry as a research tool for both the within- and cross-case analyses, I investigate participants’ accounts in interviews and e-journals, as conducted at different stages throughout the first sojourn term. Poststructuralist-constructivist conceptualizations of learner identities and beliefs guide the data analysis and interpretation. The results of the holistic and categorical content analyses give insight into the intricate relationship between beliefs about pronunciation and learners’ identity work. In their narratives, learners appear to actively use pronunciation as a tool to construct identity facets in correspondence to specific communities of practice, giving meaning to their investment in the sojourn experience. This process of mediating between different identity constructions appears to be highly complex and partially conflict-laden. The participants’ beliefs and reported learning behaviours are interconnected with their definitions of learning goals, which draw on native-speaker ideals to different extents and with varying results. These orientations are in turn related to the subjects’ degrees of critical language awareness, the latter a factor that appears to play a vital role in shaping the ability of learners to take advantage of learning opportunities. In assessing participants’ learning objectives and their readiness to reflect upon their beliefs and orientations, my study also sheds light on the influence of different learning factor constellations on intercultural learning. The results indicate that unidirectional cause-and-effect relationships cannot be drawn between learners’ beliefs about pronunciation and their abilities to approach their roles as intercultural speakers in sojourn environments. My study rather underlines the importance of illuminating individual learning experiences in their idiosyncrasies and complexities, which may lead to a stronger consideration of learners’ subjective stances in both research and teaching practice. The findings of my study suggest that the primary way that language pedagogy can thus foster the ability to engage in intercultural encounters is by helping learners to become aware of their subjective stances, their self-constructions, and the influence of those on the learning process. Therefore, developing the ability and willingness to critically reflect is crucial, especially with regard to pronunciation. In illuminating the intricate nature of learner beliefs and their influence on the learning process, my study demonstrates the importance of qualitative, emic research into the acquisition of L2 pronunciation.

AB - In this paper an approach for automatic feature classification based on their motion in the image plane is introduced. By combining concepts of the human perception of motion with techniques belonging to the area of cluster analysis, we subsequently abstract the visual data in order to separate features, whose motion is caused by the sensor motion from features, which possibly belong to dynamic objects in the environment. The presented algorithm exclusively works on data, that can be extracted from the two dimensional image plane. Hence, no external data like the current motion of the applied camera is required. Furthermore, the algorithm works on any type of tracked feature, as long as it can be statistically represented. The results of the presented approach constitute a very good starting point for additional object detection mechanisms.

AB - This paper introduces a novel method for registering a large amount of aerial images when camera parameters are almost unknown and no reference images are available. The envisioned application is the creation of an overview map of a disaster area from images made by unmanned aerial vehicles (UAVs) equipped with cameras. The camera systems only have uncertain information about flight attitude. With traditional methods, the relatively small perspective errors per image sum up over time resulting in perspective errors which prevent building a consistent map from successively arriving images. By using virtual forces between images, the image parameters are continuously adapted to the current map. The small projective errors of quasi orthographic images are distributed among overlapping images. Having UAVs which deliver quasi orthographic images, our approach can build a contemporary overview without the need to have all images in advance.

AB - During rescue scenarios it is indispensable to obtain an overview of the situation. Unmanned aerial vehicles (UAVs) can gather the necessary information in a fast and efficient way. This paper presents an approach for path planning in 3D environments offering a solution to explore disaster areas including, e.g., partially or completely destroyed buildings. Using multiple UAVs decreases the time needed to receive a complete overview if the problem of coordination and task allocation is solved. We present an approach for the use of multiple UAVs. The UAVs work in a distributed manner without any central coordination instance and cover the exploration of terrains as well as goal-oriented path planning. When using multiple UAVs redundant exploration is avoided through the use of inter-UAV-communication. The approach is based on potential fields and uses the simplicity of the gradient method to calculate paths for fast exploration of the terrain.

AB - In this paper, we introduce a test bed for demonstrating and investigating self-x properties, such as self-optimization and self-organization, within the scope of multi-robot societies under realistic conditions. By doing so, we shift the investigation and demonstration of biologically inspired mechanisms from the simulative point of view to a dynamic and more complex realistic environment. For this purpose, we developed a controlled real-world environment to overcome common problems such as self-localization. Furthermore, we elaborated a concept for a descriptive robotic real-world game. By means of this game, we provide an instrument, which is easily accessible for any kind of audience on the one hand, while it still leaves enough space for an extensive scientific investigation on the other hand.

AB - Machines are omnipresent. They produce, they transport. Machines facilitate work and assist. The increasing penetration of mechanical engineering by information technology enables considerable benefits. We refer to such systems as advanced mechatronic systems, which relay on the close interaction of mechanics, electric/electronics, control engineering and software engineering. Hence, the design and production of such systems is an interdisciplinary and complex task. Our ambition is a new school for the design of advanced mechatronic systems. Consequently, we need an avant-garde basic system which can be used to develop and to test future applications. The miniature robot BeBot is such a basic system. This robot constitutes the test bench for the applications, being based on modern approaches, such as self-optimization, self-organization and self-coordination as well as on the use of new manufacturing technologies.

AB - In the area of dynamic verification of virtual prototypes, functional coverage is a valuable tool for answering the "Are we done?" question and achieving verification closure. Recent verification methodologies such as OVM and UVM contain multi-language support that provides a basic SystemC version. However, due to language shortcoming they cannot be utilized for the same amount of verification tasks in the SystemC ecosystem as in other supported hardware design and verification languages. In this presentation, we propose to boost the verification capabilities of SystemC by implementing functional coverage collection and evaluation according to the same metric as defined in the widely accepted IEEE-1800 SystemVerilog cover group feature. We implement a functional coverage library to enable coverage-driven verification of SystemC designs on multiple levels of abstraction enabling value, transition, and expression coverage. To our knowledge, the overall functionalities are not available in the IEEE-1666 SystemC standard or the SCV add-on library, nor are they complete compared to the aforementioned in any publicly available SystemC library.

AB - Planar graph routing works provably correct if the underlying network graph is connected and planar. Typically, wireless networks modeled as 2D graphs, are not planar and planar graph routing applied on such unprocessed network graphs may fail. Planarizing a given connected graph by removing intersecting links might be impossible if the outcome still needs to be a connected subgraph. It becomes even more difficult with distributed planarization techniques, where each node is allowed to use only the information about its local neighborhood. Furthermore, it is getting complicated if the nodes' assigned positions do not reflect the exact physical location. With or without exact location information, the outcome might be disconnected, nonplanar, or both of it. With all these unsolvable problems, the question arises how to apply planar graph routing in a realistic network setting? Fortunately, wireless network graphs bear one property which distinguishes them from arbitrary graphs: due to limited communication range, network links cannot become arbitrarily long. In this work we exploit this locality property to build a new localized planarization algorithm, which is location fault tolerant and which produces planar connected graphs in most cases in realistic wireless models. We evaluate our algorithm using the Log Normal Shadowing model and show that our algorithm always produces planar connected graphs in all simulations even when large location errors are present.

AB - SystemC is a versatile C++ based design and verification language, offering various mechanisms and constructs required for embedded systems modeling. Using the add-on SystemC Verification Library (SCV) elemental constrained-random stimuli techniques may be used for verification. However, SCV has several drawbacks such as lack of a functional coverage facility supporting coverage collection on RTL and TLM models. In this article we present a functional coverage library which implements parts of the IEEE 1800-2005 SystemVerilog standard capturing functional coverage throughout the design and verification process, and allows to facilitate coverage-driven verification in SystemC.

AB - UML profiles like SysML and MARTE have been a major research topic in electronic system design, but are mainly applied for specification and analysis in early design phases. High-Level Synthesis (HLS), however, addresses the physical implementation aspect of electronic systems, and thus leads to different requirements on the accuracy of models. For this, modular interfaces are a novel object-oriented synthesizable technique to overcome the conflict between a higher degree of abstraction and necessary details for further synthesis. In this paper, we present our approach to use SysML as an adequate modeling language for modular interfaces and C/C++/SystemC-based HLS. We extended SysML with annotations for synthesizable SystemC and high-level synthesis constraints and implemented a code generation scheme to achieve design flow automation. Based on the SysML editor Artisan Studio and an industrial case study, we demonstrate the applicability of SysML as a retargetable front-end for HLS design flows.

AB - Mutation analysis is a powerful tool for white-box testing of the verification environment in order to produce dependable and higher quality software products. However, due to high computational costs and the focus on high-level software languages such as Java mutation analysis is not yet widely used in commercial design flows targeting embedded (software) systems. Here the industry is modeling both hardware and related software parts at higher levels of abstraction, called virtual prototypes, to accelerate parallel development and shorten time-to-market. In this paper we propose a mutation testing verification flow for SystemC based virtual prototypes that may not rely on source code only but on annotated basic blocks and enables mutant creation at assembler level to heavily reduce execution costs and equivalence mutants likelihood.

AB - In this paper we introduce an infrastructure for investigating Organic Computing principles such as self-optimization and self-organization in real-world scenarios based on a heterogeneous society of robots. This infrastructure, the R3PB-Workbench (Remote Real Robots at the University of Paderborn), provides a controlled environment for conducting real-world multi robot experiments, while relieving the developer from common problems like getting a global view of the entire environment and self-localization within this environment. In addition, it provides a communication layer that hides the heterogeneity of the controlled robot types and also facilitates access to each robot's subjective view. Currently we provide three types of mobile robots with different size and capabilities. Since the workbench is easily customizable, it supports the integration of additional types of robots. Hence, the degree of heterogeneity of the robot group conducting the experiments in the scope of our real-world scenario can be modified as needed. Furthermore, we elaborated a multi-robot game as an illustrative real-world scenario, which on the one hand allows for sophisticated scientific investigations and on the other hand is also appealing for an audience, even with little technical background.

AB - In this article we present an approach that enables robots to learn how to act and react robustly in continuous and noisy environments while not loosing track of the overall feasibility, i.e. minimising the execution time in order to keep up continuous learning. We do so by combining reinforcement learning mechanisms with techniques belonging to the field of multivariate statistics on three different levels of abstraction: the motivation layer and the two simultaneously learning strategy and skill layers. The motivation layer allows for modelling occasionally contradicting goals in terms of drives in a very intuitive fashion. A drive represents one single goal, that a robot wants to be satisfied, like charging its battery, when it is nearly exhausted, or transporting an object to a target position. The strategy layer encapsulates the main reinforcement learning algorithm based on an abstracted and dynamically adjusted Markovian state space. By means of state abstraction, we minimise the overall state space size in order to ensure feasibility of the learning process in a dynamically changing environment. The skill layer finally realises a generalised learning method for learning reactive low-level behaviours, that enable a robot to interact with the environment.

AB - The paradigm of imitation provides a powerful means for increasing the overall learning speed in a group of robots. While separately exploring the environment in order to learn how to behave with respect to a pre-defined goal, a robot gathers experience based on its own actions and interactions with the surroundings, respectively. By accumulating additional experience via observing the behaviour of other robots, the learning process can be significantly improved in terms of speed and quality. Within this article we present an approach, that enables robots in a multi-robot society to imitate any other available robot without imposing unnecessary restrictions regarding the robots design. Therefore, it benefits not only from its own actions, but also from actions that an observed robot performs. In order to realise the imitation paradigm, we solve three main challenges, namely enabling a robot to decide whom and when to imitate, to interpret and thereby understand the behaviour of an observed robot, and to integrate the experience gathered by observation into its individual learning process.

AB - AbstractObjectiveNutrition-related health problems such as obesity are frequent among children and adolescents of Turkish descent living in Germany, yet data on their dietary habits are scarce. One reason might be the lack of validated assessment tools for this target group. We therefore aimed to validate protein and K intakes from one 24 h recall against levels estimated from one 24 h urine sample in children and adolescents of Turkish descent living in Germany.DesignCross-sectional analyses comprised estimation of mean differences, Pearson correlation coefficients, cross-classifications and Bland–Altman plots to assess the agreement between the nutritional intake estimated from a single 24 h recall and a single 24 h urine sample collected on the previous day.SettingDortmund, Germany.SubjectsData from forty-three study participants (aged 5–18 years; 26 % overweight) with a traditional Turkish background were included.ResultsThe 24 h recall significantly overestimated mean protein and K intake by 10·7 g/d (95 % CI of mean difference: 0·6, 20·7 g/d) and 344 mg/d (95 % CI 8, 680 mg/d), respectively. Correlations between intake estimates were r = 0·25 (P = 0·1) and 0·31 (P = 0·05). Both methods classified 70 % and 69 % of the participants into the same/adjacent quartile of protein and K intake and misclassified 7 % and 7 %, respectively, into the opposite quartile. Bland–Altman plots indicated a wide scattering of differences in both protein and K intake.ConclusionsAmong children and adolescents of traditional Turkish descent living in Germany, one 24 h recall may only be valid for categorizing subjects into high, medium or low consumers.
