  abstract  = {Modern distributed engineering applications are based on complex systems consisting of various subsystems that are connected through the Internet. Communication and collaboration within an entire system requires reliable and efficient data exchange between the subsystems. Middleware developed within the web evolution during the past years provides reliable and efficient data exchange for web applications, which can be adopted for solving the data exchange problems in distributed engineering applications. This paper presents a generic approach for reliable and efficient data exchange between engineering devices using existing middleware known from web applications. Different existing middleware is examined with respect to the suitability in engineering applications. In this paper, a suitable middleware is shown and a prototype implementation simulating distributed wind farm control is presented and validated using several performance measurements.},

  abstract  = {Nanostructured materials are extensively applied in many fields of material science for new industrial applications, particularly in the automotive, aerospace industry due to their exceptional physical and mechanical properties. Experimental testing of nanomaterials is expensive, timeconsuming,challenging and sometimes unfeasible. Therefore,computational simulations have been employed as alternative method to predict macroscopic material properties. The behavior of polymeric nanocomposites (PNCs) are highly complex. The origins of macroscopic material properties reside in the properties and interactions taking place on finer scales. It is therefore essential to use multiscale modeling strategy to properly account for all large length and time scales associated with these material systems, which across many orders of magnitude. Numerous multiscale models of PNCs have been established, however, most of them connect only two scales. There are a few multiscale models for PNCs bridging four length scales (nano-, micro-, meso- and macro-scales). In addition, nanomaterials are stochastic in nature and the prediction of macroscopic mechanical properties are influenced by many factors such as fine-scale features. The predicted mechanical properties obtained by traditional approaches significantly deviate from the measured values in experiments due to neglecting uncertainty of material features. This discrepancy is indicated that the effective macroscopic properties of materials are highly sensitive to various sources of uncertainty, such as loading and boundary conditions and material characteristics, etc., while very few stochastic multiscale models for PNCs have been developed. Therefore, it is essential to construct PNC models within the framework of stochastic modeling and quantify the stochastic effect of the input parameters on the macroscopic mechanical properties of those materials. This study aims to develop computational models at four length scales (nano-, micro-, meso- and macro-scales) and hierarchical upscaling approaches bridging length scales from nano- to macro-scales. A framework for uncertainty quantification (UQ) applied to predict the mechanical properties of the PNCs in dependence of material features at different scales is studied. Sensitivity and uncertainty analysis are of great helps in quantifying the effect of input parameters, considering both main and interaction effects, on the mechanical properties of the PNCs. To achieve this major goal, the following tasks are carried out: At nano-scale, molecular dynamics (MD) were used to investigate deformation mechanism of glassy amorphous polyethylene (PE) in dependence of temperature and strain rate. Steered molecular dynamics (SMD)were also employed to investigate interfacial characteristic of the PNCs. At mico-scale, we developed an atomistic-based continuum model represented by a representative volume element (RVE) in which the SWNT's properties and the SWNT/polymer interphase are modeled at nano-scale, the surrounding polymer matrix is modeled by solid elements. Then, a two-parameter model was employed at meso-scale. A hierarchical multiscale approach has been developed to obtain the structure-property relations at one length scale and transfer the effect to the higher length scales. In particular, we homogenized the RVE into an equivalent fiber. The equivalent fiber was then employed in a micromechanical analysis (i.e. Mori-Tanaka model) to predict the effective macroscopic properties of the PNC. Furthermore, an averaging homogenization process was also used to obtain the effective stiffness of the PCN at meso-scale. Stochastic modeling and uncertainty quantification consist of the following ingredients: - Simple random sampling, Latin hypercube sampling, Sobol' quasirandom sequences, Iman and Conover's method (inducing correlation in Latin hypercube sampling) are employed to generate independent and dependent sample data, respectively. - Surrogate models, such as polynomial regression, moving least squares (MLS), hybrid method combining polynomial regression and MLS, Kriging regression, and penalized spline regression, are employed as an approximation of a mechanical model. The advantage of the surrogate models is the high computational efficiency and robust as they can be constructed from a limited amount of available data. - Global sensitivity analysis (SA) methods, such as variance-based methods for models with independent and dependent input parameters, Fourier-based techniques for performing variance-based methods and partial derivatives, elementary effects in the context of local SA, are used to quantify the effects of input parameters and their interactions on the mechanical properties of the PNCs. A bootstrap technique is used to assess the robustness of the global SA methods with respect to their performance. In addition, the probability distribution of mechanical properties are determined by using the probability plot method. The upper and lower bounds of the predicted Young's modulus according to 95 \% prediction intervals were provided. The above-mentioned methods study on the behaviour of intact materials. Novel numerical methods such as a node-based smoothed extended finite element method (NS-XFEM) and an edge-based smoothed phantom node method (ES-Phantom node) were developed for fracture problems. These methods can be used to account for crack at macro-scale for future works. The predicted mechanical properties were validated and verified. They show good agreement with previous experimental and simulations results.},

  abstract  = {What is nowadays called (classic) Clifford analysis consists in the establishment of a function theory for functions belonging to the kernel of the Dirac operator. While such functions can very well describe problems of a particle with internal SU(2)-symmetries, higher order symmetries are beyond this theory. Although many modifications (such as Yang-Mills theory) were suggested over the years they could not address the principal problem, the need of a n-fold factorization of the d'Alembert operator. In this paper we present the basic tools of a fractional function theory in higher dimensions, for the transport operator (alpha = 1/2 ), by means of a fractional correspondence to the Weyl relations via fractional Riemann-Liouville derivatives. A Fischer decomposition, fractional Euler and Gamma operators, monogenic projection, and basic fractional homogeneous powers are constructed.},

One of the crack edges is reinforced by a rigid patch plate on a finite interval adjacent to the crack tip. The crack edges are loaded with specified stresses. The body is stretched at infinity by specified stresses. External forces with a given principal vector and moment act on the patch plate. The problem reduces to a Riemann-Hilbert boundary-value matrix problem with a piecewise-constant coefficient for two complex potentials in the plane case and for one in the antiplane case. The complex potentials are found explicitly using a Gaussian hypergeometric function. The stress state of the body close to the ends of the patch plate, one of which is also simultaneously the crack tip, is investigated. Stress intensity factors near the singular points are determined.},

  abstract  = {From the design experiences of arch dams in the past, it has significant practical value to carry out the shape optimization of arch dams, which can fully make use of material characteristics and reduce the cost of constructions. Suitable variables need to be chosen to formulate the objective function, e.g. to minimize the total volume of the arch dam. Additionally a series of constraints are derived and a reasonable and convenient penalty function has been formed, which can easily enforce the characteristics of constraints and optimal design. For the optimization method, a Genetic Algorithm is adopted to perform a global search. Simultaneously, ANSYS is used to do the mechanical analysis under the coupling of thermal and hydraulic loads. One of the constraints of the newly designed dam is to fulfill requirements on the structural safety. Therefore, a reliability analysis is applied to offer a good decision supporting for matters concerning predictions of both safety and service life of the arch dam. By this, the key factors which would influence the stability and safety of arch dam significantly can be acquired, and supply a good way to take preventive measures to prolong ate the service life of an arch dam and enhances the safety of structure.},

In real estate marketing social discourses are used as a source of reference for place branding or identity design. Branding concepts therefore relate to how social groups imagine their position or future position in society, imaginaries that are continuously influenced and changed by social dynamics within the city but also from the outside. How such urban identities are formed and it what way they relate to the urban environment is crucial to a wide spectrum of social and cultural science. The constitutive role urban space attains has been described and analysed in much detail. Such scrutiny however has yet to be applied to the visual and communicative forms of engagement, the build environment partakes in the formation and change of social discourses.},

This is not the case with liquid-filled acoustic resonators of non-trivial geometries, where several masses and stiffnesses of the structure and the fluid have to fit together. This creates a scenario of many competing and interacting resonances varying in relative strength and frequency when design parameters change. Hence, the resonator design involves a parameter-tuning problem with many local optima. As its solution evolutionary algorithms (EA) coupled to a forced-harmonic FE simulation are presented. A new hybrid EA is proposed and compared to two state-of-theart EAs based on selected test problems. The motivating background is the search for better resonators suitable for sonofusion experiments where extreme states of matter are sought in collapsing cavitation bubbles.},

  abstract  = {Fließmittel werden in Betonen verwendet, um deren Fließeigenschaften w{\"a}hrend der Verarbeitung zu verbessern und Wasser einzusparen. Beide Faktoren beeinflussen nicht nur den Frischbeton, sondern auch signifikant die Festbetoneigenschaften. Nachteilig wirken sich Fließmittel auf die Festigkeitsentwicklung aus, die z.T. sehr stark verz{\"o}gert wird. Dies ist vor allem bei Bauteilen, die im Rahmen eines Vorfertigungsprozesses hergestellt werden, ein {\"o}konomischer Nachteil. Die vorliegende Arbeit widmet sich den Ursachen f{\"u}r die Verz{\"o}gerung der Portlandzementhydratation bei Verwendung von Fließmitteln. Um die komplexen Reaktionen, die w{\"a}hrend der Portlandzementhydratation auftreten, zu vereinfachen, betrachtet ein {\"u}berwiegender Teil der Arbeit die Wechselwirkung Fließmittel-Tricalciumsilikat (Abk. Ca3SiO5 oder C3S, Hauptbestandteil von Portlandzementklinker). Die Untersuchungen werden in drei Hauptteilen durchgef{\"u}hrt, wobei Methoden wie u.a. isotherme W{\"a}rmeflusskalorimetrie, Elektrische Leitf{\"a}higkeit, Elektronenmikroskopie, ICP-OES, TOC als auch Analytische Ultrazentrifugation Anwendung finden. Basierend auf der Wechselwirkung von Kationen mit anionischen Ladungstr{\"a}gern von Polymeren wird die Interaktion von Calcium mit Fließmitteln im ersten Teil der Arbeit untersucht. Dabei kommt es {\"u}berwiegend zur Komplexierung von Calciumionen durch die funktionellen Gruppen der Plymere (Carboxyl- bzw. Sulfonguppen), die in zement{\"a}ren Umgebungen sowohl gel{\"o}st in der w{\"a}ssrigen Phase als auch als Bestandteil von Partikelgrenzfl{\"a}chen vorhanden sind. Neben diesen Effekten kann auch gezeigt werden, dass Fließmittel die Bildung von nanoskaligen Partikeln hervorrufen, die infolge der sterischen Wirkung von Fließmitteln dispergiert in der w{\"a}ssrigen Phase vorliegen (Clusterbildung). Analog zu neuesten Erkenntnissen aus dem Bereich der Biomineralisation ist daher davon auszugehen, dass diese Nanopartikel durch Agglomeration das Kristallwachtsum beeinflussen. Ausgehend von der Annahme, dass die Aufl{\"o}sungs- und/ oder F{\"a}llungskinetik durch die Wirkung von Fließmitteln behindert und damit f{\"u}r den Verz{\"o}gerungseffekt der Fließmittel w{\"a}hrend der komplexen Hydratationsreaktion verantwortlich seien k{\"o}nnen, werden die zugrundeliegenden Vorg{\"a}nge im zweiten Abschnitt getrennt voneinander untersucht. Es wird anhand von L{\"o}sungsuntersuchungen an C-S-H Phasen und Portlandit herausgestellt, dass die Komplexierung von gel{\"o}sten Calciumionen durch funktionelle Gruppen der Polymere die L{\"o}slichkeit von Portlandit erh{\"o}ht. Im Gegensatz f{\"u}hrt die Komplexierung von Calciumionen in der w{\"a}ssrigen Phase zu einer Verringerung der Calciumionenkonzentration in der w{\"a}ssrigen Phase. Diese Effekte werden auf die unterschiedlich starke Adsorptionsneigung der Polymere an C-S-H-Phasen und Portlandit zur{\"u}ckgef{\"u}hrt. Es wird davon ausgegangen, dass die Adsorption aufgrund der gr{\"o}ßeren spezifischen Oberfl{\"a}che st{\"a}rker an den C-S-H-Phasen als am Portlandit auftritt. Demnach stellt sich dar, dass die Polymere erst nachdem die funktionellen Gruppen Calciumionen aus der w{\"a}ssrigen Phase komplexiert haben an den C-S-H-Phasen adsorbieren. Weiterhin kann gezeigt werden, dass die freie C3S Aufl{\"o}sungsrate in Anwesenheit von Fließmitteln keinen direkten Zusammenhang zur Verz{\"o}gerung erkennen l{\"a}sst. Teilweise kommt es zu einer in Bezug zur Kontrollprobe ohne Fließmittel erh{\"o}hten sowie auch verringerten Aufl{\"o}sungsrate. Wird das Komplexierungsvem{\"o}gen der Fließmittel ber{\"u}cksichtigt, so kann durchaus eine verlangsamte freie Aufl{\"o}sungsrate ermittelt werden. Doch auch Calcit zeigt einen verz{\"o}gernden Einfluss auf die freie C3S Aufl{\"o}sung, obwohl es den Gesamtprozess der Hydratation signifikant beschleunigt. Somit kann die behinderte Aufl{\"o}sung als m{\"o}gliche Ursache f{\"u}r die verz{\"o}gernde Wirkung w{\"a}hrend der Zementhydratation weder best{\"a}tigt noch widerlegt werden. Dieser Punkt sollte in zuk{\"u}nftigen Arbeiten weiter untersucht werden. Im letzten Schritt dieses Untersuchungsabschnitts wird die reine Kristallisation von C-S-H-Phasen und Portlandit untersucht. Es stellt sich heraus, dass Fließmittel insbesondere durch die Wirkung der Komplexierung von Ionen in der w{\"a}ssrigen Phase sowohl die Induktionszeit verl{\"a}ngern als auch die Kristallwachstumsrate ver{\"a}ndern. Dies allein kann aber nicht die komplette Verz{\"o}gerungswirkung erkl{\"a}ren. Ein wichtiger Verz{\"o}gerungsfaktor ist die Adsorption der Polymere an Kristalloberfl{\"a}chen als auch eine fließmittelbedingte Dispergierung von nanoskaligen Einzelpartikeln, die deren Agglomeration zu Kristallen behindert. Im letzten Hauptuntersuchungsabschnitt werden die gewonnenen Erkenntnisse auf die w{\"a}hrend der Zement- und Tricalciumsilikathydratation parallel ablaufenden Reaktionen analysiert. Dabei wird insbesondere die ionische Zusammensetzung der w{\"a}ssrigen Phase von C3S Pasten und Suspensionen untersucht, um Hinweise f{\"u}r eine kinetische Hemmung der Hydratationsreaktion zu identifizieren. Zusammenfassend wird festgestellt, dass die Ursachen der verz{\"o}gernden Wirkung von Fließmitteln auf die Hydratation von C3S auf die starke Verz{\"o}gerung der Kristallisation von Hydratphasen zur{\"u}ckzuf{\"u}hren ist. Dabei kommt den zwei Faktoren Komplexierung von Calciumionen an Oberfl{\"a}chen und Stabilisierung von nanoskaligen Partikeln eine zentrale Bedeutung zu. Diese Effekte k{\"o}nnen durch die Wirkung als Templat als auch durch Erh{\"o}hung der L{\"o}slichkeit infolge Komplexierung freier/gel{\"o}ster Ionen teilkompensiert werden. Dass die Aufl{\"o}sungsreaktion durch die Anwesenheit von Fließmitteln behindert wird, kann nur indirekt anhand der Entwicklung von Ionenkonzentrationen festgestellt werden. Ob dieser Vorgang die Ursache oder die Folge des L{\"o}sungs-F{\"a}llungs-Mechanismus der Hydratation ist und damit die verz{\"o}gernde Wirkung durch behinderte Aufl{\"o}sung des Edukts hervorgerufen wird, bleibt Gegenstand weiterer Untersuchungen. Im Rahmen der Arbeit kann auch gezeigt werden, dass Fließmittel chemisch als Inhibitoren wirken indem sie den Frequenzfaktor verringern. Dar{\"u}ber hinaus wird erstmalig eine Methode entwickelt, die die Bestimmung der Ionenkonzentration in Pasten in-situ erlaubt. Mit deren Hilfe wird dargestellt, dass die Entwicklung der Ionenkonzentration als auch die allgemein verwendete W{\"a}rmefreisetzungsrate (Kalorimetrie) miteinander korrespondiert. Dar{\"u}ber hinaus erlaubt die entwickelte Methode die weitere Differenzierung der Accelerationsperiode in drei Stadien. Die Kristallisation von C-S-H-Phasen und Portlandit ist f{\"u}r den Beginn der Haupthydratationsperiode entscheidend.},

State-of-the-art sensor nodes, collecting structural and environmental data from civil infrastructure systems, are capable of processing and analyzing the data sets directly on-board the nodes. Structural health monitoring (SHM) based on sensor nodes that possess so called "on-chip intelligence" is, in this study, referred to as "intelligent SHM", and the infrastructure system being equipped with an intelligent SHM system is referred to as "intelligent infrastructure". Although intelligent SHM will continue to grow, it is not possible, on a well-defined formalism, to digitally represent information about sensors, about the overall SHM system, and about the monitoring strategies being implemented ("monitoring-related information"). Based on a review of available SHM regulations and guidelines as well as existing sensor models and sensor modeling languages, this conceptual paper investigates how to digitally represent monitoring-related information in a semantic model. With the Industry Foundation Classes, there exists an open standard for the digital representation of building information; however, it is not possible to represent monitoring-related information using the IFC object model. This paper proposes a conceptual approach for extending the current IFC object model in order to include monitoring-related information. Taking civil infrastructure systems as an illustrative example, it becomes possible to adequately represent, process, and exchange monitoring-related information throughout the whole life cycle of civil infrastructure systems, which is referred to as monitoring information modeling (MIM). However, since this paper is conceptual, additional research efforts are required to further investigate, implement, and validate the proposed concepts and methods.},

Die gezeigten L{\"o}sungsans{\"a}tze bewegen sich dabei im Spannungsfeld von Architektur und Ingenieurbau, denn die gefalteten Bauteile sind nicht nur {\"a}ußerst tragf{\"a}hig sondern besitzen auch eine {\"a}sthetische Form. Die entwickelten Verfahren und Konstruktionen werden auf einem hohen architektonischen Niveau pr{\"a}sentiert und mit einfachen ingenieurtechnischen Methoden verifiziert. Zur L{\"o}sungsfindung werden geometrische Verfahren ebenso angewendet wie konstruktive Faustformeln und Recherchen aus Architektur und Forschung. Der Fokus der Arbeit liegt auf der Untersuchung von Faltungen in Wabenplatten. W{\"a}hrend der Auseinandersetzung mit der Thematik erschienen jedoch viele weitere Aspekte als sehr interessant und bearbeitungsw{\"u}rdig. Als theoretische Grundlage dieser Arbeit werden deshalb die geschichtliche Entwicklung und die gesellschaftliche Bedeutung von Papier und Papierwerkstoffen analysiert und deren Produktionsprozesse beleuchtet. Diese Vorgehensweise erm{\"o}glicht eine Einordnung des Potentials und der Bedeutung des Werkstoffs Papier. Der Kontext der Arbeit wird dadurch gest{\"a}rkt und f{\"u}hrt zu interessanten zuk{\"u}nftigen Forschungsans{\"a}tzen. Intensive Untersuchungen widmen sich der geometrischen Bestimmung von Faltungen in Wabenplatten aus Papierwerkstoffen sowie deren Manifestation als konstruktive Bauteile. Auch die statischen Eigenschaften der Elemente und ihr Konstruktionspotential werden erforscht und aufbereitet. Wichtige Impulse aus Forschung und Technik fließen in die Recherche der Arbeit ein und erlauben die Verortung der Ergebnisse im architektonischen Kontext. Versuchsreihen und Materialstudien an Prototypen belegen die Ergebnisse virtueller und rechnerischer Studien. Konzepte zur parametrischen Berechnung und Visualisierung der Forschungsergebnisse werden pr{\"a}sentiert und zeigen zukunftsf{\"a}hige Planungshilfen f{\"u}r die Industrie auf. Etliche Testreihen zu unterschiedlichsten Abdichtungskonzepten f{\"u}hren zur Realisierung eines sehenswerten Experimentalbaus. Er erlaubt die dauerhafte Untersuchung der entwickelten Bauteile unter realistischen Bedingungen und best{\"a}tigt deren Leistungsf{\"a}higkeit. Dadurch wird nicht nur ein dauerhaftes Monitoring und eine Evaluierung der Leistungsdaten m{\"o}glich sondern es wird auch der sichtbare Beweis erbracht, dass mit Papierwerkstoffen effiziente und hochwertige Architekturen zu realisieren sind, welche das enorme gestalterische Potential von gefalteten Wabenplatten ausnutzen.},

Do the light designers take into consideration criteria to protect not only historic buildings and monuments, but also the environment? What are the consequences that may generate the inadequate lighting of urban heritage to the environment? What are the factors to consider for a proper illumination of urban heritage? The answers to these questions will help lay the foundation for proper illumination of the urban heritage, avoiding at the maximum the light pollution and the effects that it generates, seeking a balance and harmonious reconciliation between the technology, urban heritage and environment, taking as a framework and the case study the urban heritage of a city from the colonial era in southern Mexico, with pre-Hispanic roots and where today you can still see through its streets and buildings an atmosphere of mysticism reflection of their folklore and traditions, this city is known as Chiapa de Corzo, Chiapas.},

Since a minimal parameterization of the metric trifocal tensor is challenging, the additional constraints of the interior orientation are applied to the well-known projective 6-point and 7-point algorithms for three images. The experimental results show that the linear 7-point algorithm fails for some noise-free degenerated cases, whereas the minimal 6-point algorithm seems to be competitive even with realistic noise.},

  abstract  = {This thesis presents new interactive visualization techniques and systems intended to support users with real-world decisions such as selecting a product from a large variety of similar offerings, finding appropriate wording as a non-native speaker, and assessing an alleged case of plagiarism. The Product Explorer is a significantly improved interactive Parallel Coordinates display for facilitating the product selection process in cases where many attributes and numerous alternatives have to be considered. A novel visual representation for categorical and ordered data with only few occurring values, the so-called extended areas, in combination with cubic curves for connecting the parallel axes, are crucial for providing an effective overview of the entire dataset and to facilitate the tracing of individual products. The visual query interface supports users in quickly narrowing down the product search to a small subset or even a single product. The scalability of the approach towards a large number of attributes and products is enhanced by the possibility of setting some constraints on final attributes and, therefore, reducing the number of considered attributes and data items. Furthermore, an attribute repository allows users to focus on the most important attributes at first and to bring in additional criteria for product selection later in the decision process. A user study confirmed that the Product Explorer is indeed an excellent tool for its intended purpose for casual users. The Wordgraph is a layered graph visualization for the interactive exploration of search results for complex keywords-in-context queries. The system relies on the Netspeak web service and is designed to support non-native speakers in finding customary phrases. Uncertainties about the commonness of phrases are expressed with the help of wildcard-based queries. The visualization presents the alternatives for the wildcards in a multi-column layout: one column per wildcard with the other query fragments in between. The Wordgraph visualization displays the sorted results for all wildcards at once by appropriately arranging the words of each column. A user study confirmed that this is a significant advantage over simple textual result lists. Furthermore, visual interfaces to filter, navigate, and expand the graph allow interactive refinement and expansion of wildcard-containing queries. Furthermore, this thesis presents an advanced visual analysis tool for assessing and presenting alleged cases of plagiarism and provides a three-level approach for exploring the so-called finding spots in their context. The overview shows the relationship of the entire suspicious document to the set of source documents. An intermediate glyph-based view reveals the structural and textual differences and similarities of a set of finding spots and their corresponding source text fragments. Eventually, the actual fragments of the finding spot can be shown in a side-by-side view with a novel structured wrapping of both the source, as well as the suspicious text. The three different levels of detail are tied together by versatile navigation and selection operations. Reviews with plagiarism experts confirm that this tool can effectively support their workflow and provides a significant improvement over existing static visualizations for assessing and presenting plagiarism cases. The three main contributions of this research have a lot in common aside from being carefully designed and scientifically grounded solutions to real-world decision problems. The first two visualizations facilitate the decision for a single possibility out of many alternatives, whereas the latter ones deal with text at varying levels of detail. All visual representations are clearly structured based on horizontal and vertical layers contained in a single view and they all employ edges for depicting the most important relationships between attributes, words, or different levels of detail. A detailed analysis considering the context of the established decision-making literature reveals that important steps of common decision models are well-supported by the three visualization systems presented in this thesis.},

  abstract  = {Media anthropology is a new and interdisciplinary field of research with very different subjects and methods that seems to be already heavily informed by a comparatively narrow understanding of media as mass media (e.g. TV, Internet, social web, etc.). Therefore, most theories in this field, at least implicitly, employ a hierarchical and often dichotomic preconception of the two poles of media-human relations, by analysing the operationalities and ontologies of the human and the media independently from one another. This article deviates from this line of thought by advocating an expanded, symmetrical and relational understanding of the terms media and human, taking them as always already intermingled facets of a broader dynamic configuration. Starting from a consideration of the historically powerful, yet overlooked media of the so-called habitat diorama, the heuristic concept of "anthropomediality" is to be developed. Eventually, this relational approach may open up a new, interesting field for interrogation of (media-)anthropological analysis in general.},

  abstract  = {The article presents preliminary results and qualitative analysis obtained from the doctoral research provisory entitled "How do Brazilian 'battlers' reside?", which is in progress at the Institute for European Urban Studies, Bauhaus Univer-sity Weimar. It critically discusses the contradictions of the production of residences in Brazil made by an emerging so-cial group, lately called the Brazilian new middle class. For the last ten years, a number of government policies have provoked a general improvement of the purchasing power of the poor. Between those who completely depend on the government to survive and the upper middle class, there is a wide (about 100 million people) and economically stable lower middle group, which has found its own ways of dealing with its demand for housing. The conventional models of planning, building and buying are not suitable for their technical, financial and personal needs. Therefore, they are con-currently planners, constructors and residents, building and renovating their own properties themselves, but still with very limited education and technical knowledge and restricted access to good building materials and constructive ele-ments, formal technicians, architects or engineers. On the one hand, the result is an informal and more or less autono-mous self-production, with all sorts of technical problems and very interesting and creative spatial solutions to every-day domestic situations. On the other hand, the repercussions for urban space are questionable: although basic infrastructure conditions have improved, building densities are high and green areas are few. Lower middle class neigh-bourhoods present a restricted collective everyday life. They look like storage spaces for manpower; people who live to work in order to be able to consume—and build—what they could not before. One question is, to what extent the lat-est economic rise of Brazil has really resulted in social development for lower middle income families in the private sphere regarding their residences, and in the collective sphere, regarding the neighbourhoods they inhabit and the ur-ban space in general.},

According to the sensitivity of the parameters and the probability distribution of the samples we can provide confidence intervals for the estimated parameters and thus allow a qualitative estimation on the identified parameters which are in future work used as inputs for prognosis computations of buffer elements.

  abstract  = {Low-skilled labor makes a significant part of the construction sector, performing daily production tasks that do not require specific technical knowledge or confirmed skills. Today, construction market demands increasing skill levels. Many jobs that were once considered to be undertaken by low or un-skilled labor, now demand some kind of formal skills. The jobs that require low skilled labor are continually decreasing due to technological advancement and globalization. Jobs that previously required little or no training now require skilful people to perform the tasks appropriately. The study aims at ameliorating employability of less skilled manpower by finding ways to instruct them for performing constructions tasks. A review of exiting task instruction methodologies in construction and the underlying gaps within them warrants an appropriate way to train and instruct low skilled workers for the tasks in construction. The idea is to ensure the required quality of construction with technological and didactic aids seeming particularly purposeful to prepare potential workers for the tasks in construction without exposing them to existing communication barriers. A BIM based technology is considered promising along with the integration of visual directives/animations to elaborate the construction tasks scheduled to be carried on site.},

  abstract  = {This article presents the Rigid Finite Element Method in the calculation of reinforced concrete beam deflection with cracks. Initially, this method was used in the shipbuilding industry. Later, it was adapted in the homogeneous calculations of the bar structures. In this method, rigid mass discs serve as an element model. In the flat layout, three generalized coordinates (two translational and one rotational) correspond to each disc. These discs are connected by elastic ties. The genuine idea is to take into account a discrete crack in the Rigid Finite Element Method. It consists in the suitable reduction of the rigidity in rotational ties located in the spots, where cracks occurred. The susceptibility of this tie results from the flexural deformability of the element and the occurrence of the crack. As part of the numerical analyses, the influence of cracks on the total deflection of beams was determined. Furthermore, the results of the calculations were compared to the results of the experiment. Overestimations of the calculated deflections against the measured deflections were found. The article specifies the size of the overestimation and describes its causes.},

Using the EMD results, we constructed finite element models of polycrystalline h-BN sheets to probe the thermal conductivity of samples with larger grain sizes. Our multiscale investigations not only provide a general viewpoint regarding the heat conduction in h-BN films but also propose that polycrystalline h-BN sheets present high thermal conductivity comparable to monocrystalline sheets.},

Due to the professional background of the authors, this benchmarking strategy is illustrated on a selection of search methods in regard to expected characteristics of geotechnical parameter back calculation problems. Starting from brief introduction into the approach employed, a strategy for optimization algorithm benchmarking is introduced. The benchmarking utilizes statistical tests carried out on well-known test functions superposed with perturbations, both chosen to mimic objective function topologies found for geotechnical objective function topologies. Here, the moved axis parallel hyper-ellipsoid test function and the generalized Ackley test function in conjunction with an adjustable quantity of objective function topology roughness and fraction of failing forward calculations is analyzed. In total, results for 5 optimization algorithms are presented, compared and discussed.},

  abstract  = {Etwa ein Viertel des gesamten Endenergieverbrauchs (26\%) in Deutschland entf{\"a}llt auf den Wohnungssektor, wodurch dieser Sektor einen erheblichen Anteil am m{\"o}glichen Einsparpotenzial an Energie hat. Im Hinblick auf das Klimaschutzziel der Europ{\"a}ischen Union, die Energieeffizienz im Vergleich zu 1990 um 20\% zu erh{\"o}hen, stellt sich daher die Frage, welche Einsparpotenziale es im Wohnungssektor tats{\"a}chlich gibt und wie diese quantifiziert werden k{\"o}nnen. In dieser Arbeit wird der Einfluss der Parameter, die den Endenergieverbrauch beeinflussen, mit Hilfe einer Sensitivit{\"a}tsanalyse bestimmt. Die Ergebnisse der Sensitivit{\"a}tsanalyse zeigen, dass die einflussreichsten Parameter auf den Endenergieverbrauch der Innentemperaturbedarf, die L{\"a}nge der Heizperiode, die Außentemperatur (Gradtagzahl) und die Anzahl der Wohnungen sind. Dies sind Variablen, die nicht durch Verordnungen reguliert werden k{\"o}nnen. Der einzige Parameter, der regulierbar ist und einen bedeutenden Einfluss auf den Endenergieverbrauch hat, ist der Nutzungsgrad der Anlagen/Ger{\"a}te f{\"u}r Raumw{\"a}rme, Warmwasser und Kochen (sowie zu einem geringen Teil der Wirkungsgrad der eingesetzten Beleuchtung). Zur Quantifizierung des Energieeinsparpotentials im deutschen Wohnungssektor bez{\"u}glich des Nutzungsgrades wurden in dieser Arbeit Daten zur Bestimmung der langfristigen Entwicklung (Zeitraum 1990-2010) des Nutzungsgrades von Anlagen und Ger{\"a}ten analysiert. Mit verschiedenen Angaben aus der Literatur und mit Hilfe von S{\"a}ttigungskurven wurde die Entwicklung der Nutzugsgrade der Anlagen/Ger{\"a}te entsprechend der Energiequellen zwischen 1990 und 2010 ermittelt. Die erhaltenden S{\"a}ttigungskurven erm{\"o}glichen die Bestimmung der Entwicklung des Nutzenergieverbrauchs im deutschen Wohnungssektor. Hierbei wurde festgestellt, dass die Differenz zwischen Nutzenergieverbrauch und Endenergieverbrauch einen R{\"u}ckgang von 12 \% im betrachtenden Zeitraum verzeichnete und dass das Energieeinsparpotenzial in Abh{\"a}ngigkeit von der Energiequelle betr{\"a}chtlich variieren kann (um derzeit mehr als 35\%-Punkte). Im Hinblick auf das oben genannte Klimaschutzziel werden in dieser Arbeit verschiedene Entwicklungsszenarien auf Basis des Nutzungsgrades der Anlagen und der Energiequellen analysiert. Hierbei wird deutlich, dass das theoretische Energieeinsparpotenzial im deutschen Wohnungssektor bez{\"u}glich des durchschnittlichen Nutzungsgrades nur zwischen 4 und 15 \% liegt. Dies bedeutet, dass eine deutliche Reduktion des Endenergiebedarfs im Wohnungssektor nur stattfinden kann, wenn andere Energieeinsparmaßnahmen betrachtet werden. Basierend auf den Ergebnissen der Sensitivit{\"a}tsanalyse werden hierzu Empfehlungen gegeben.},

  abstract  = {Portugal is one of the European countries with higher spatial and population freeway network coverage. The sharp growth of this network in the last years instigates the use of methods of analysis and the evaluation of their quality of service in terms of the traffic performance, typically performed through internationally accepted methodologies, namely that presented in the Highway Capacity Manual (HCM). Lately, the use of microscopic traffic simulation models has been increasingly widespread. These models simulate the individual movement of the vehicles, allowing to perform traffic analysis. The main target of this study was to verify the possibility of using microsimulation as an auxiliary tool in the adaptation of the methodology by HCM 2000 to Portugal. For this purpose, were used the microscopic simulators AIMSUN and VISSIM for the simulation of the traffic circulation in the A5 Portuguese freeway. The results allowed the analysis of the influence of the main geometric and traffic factors involved in the methodology by HCM 2000. In conclusion, the study presents the main advantages and limitations of the microsimulators AIMSUN and VISSIM in modelling the traffic circulation in Portuguese freeways. The main limitation is that these microsimulators are not able to simulate explicitly some of the factors considered in the HCM 2000 methodology, which invalidates their direct use as a tool in the quantification of those effects and, consequently, makes the direct adaptation of this methodology to Portugal impracticable.},

  abstract  = {Abstract This doctoral thesis defines the relationship between the urban and rural in the 21st century, and focuses on food as a key component. The fact that food is, for the most part, produced in the countryside and then transported to the city has a significant influence on this very unbalanced relationship today. The main goal was to show that it is necessary to bring agriculture, urban gardening, the breeding of domestic farm animals, and beekeeping back to the city, which would have a positive affect on both the city and the countryside. All of this is already taking place at the local level, within the neighbourhoods of our cities and through the work of self-organised activities and initiatives, which have been taken up by city residents themselves. One example of this is the community garden, a new model of gardening which offers fertile ground for growing vegetables and to test various forms of co-existence, different ways of designing spaces, the creation of alternative values, and a positive vision for the future of city residents. In 2010, I co-created the community urban garden Beyond a Construction Site, which is the central part of this artistic research. Throughout the entire four-year process of creating this community garden, theory and artistic practice were intertwined, and informed one another. This community garden is an example of a self-organised and self-managed community space located in a residential neighbourhood in the centre of the city of Ljubljana, and as such is a typical example of urbanism from the bottom up. I placed the creation and development of our community garden in a dialogue with the formal way of arranging urban gardening in Ljubljana, a top-down approach, which the city has been carrying out intensively since 2007. I compared the solutions being proposed by the city of Ljubljana for organising urban gardening with the way it is organised in other European cities, the UK, and the USA. I also researched the recent rapid growth of self-organised initiatives which are focused on the local production of food and seek to find more economic and ecologically friendly models to visibly influence the future of cities and the countryside. Here, community gardens play an important role, as in addition to the production of food they are also spaces for the criticism of existing urban policies, a self-organised revitalisation of neglected spaces, and places of resilience, because they differ from that which real estate agencies, large financial companies, and city authorities desire them to be. The community garden Beyond a Construction Site has become living proof that, through a group action, the residents of a neighbourhood can influence existing city policies and the future of both their own neighbourhood and that of the entire city. The initiators of this garden are artists and architects, and we began this community garden in the context of an art festival, which also shows that art can influence the processes of everyday life and help to create much needed spaces within cities to serve various purposes. Our community garden has also shown itself to be an important platform for the exchange of knowledge on organic gardening, ecology in everyday life, and critical architecture, as well as serving to connect related initiatives. Together with these other initiatives we are stronger, and are influencing structural changes within city politics, thereby also co-creating the future of Ljubljana. This community garden is helping us to redefine our relationship with the city and re-awaken the desires and actions of residents connected with realising their fundamental right, the right to the city. My other artworks, which I am presenting in the context of this doctoral thesis, show an optimistic vision for the future of cities. The video animations Back to the City (2011) and The Right Balance (2013), as well as the accompanying collages, visualise a city of the future where urban and rural practices live together side-by-side. This vision is being realised by city residents themselves, with their active participation in the creation of community gardens, growing their own vegetables, urban beekeeping, and by having egg-laying hens in their gardens. My desire was also to present the theoretical concept and scientific research to a non-academic public, and to people without specialised training. Using the method of storytelling I included knowledge from the research into the video animations and collages. In this way my artistic work, with an intentional playfulness, challenges today's faith in science and theoretical concepts, as well as directing attention to working with common sense, with one's own hands, and with the earth. This can contribute to a change in the still dominant anthropocentric view of nature, which is an urgently needed change for our future.

  abstract  = {Steel profiles with slender cross-sections are characterized by their high susceptibility to instability phenomena, especially local buckling, which are intensified under fire conditions. This work presents a study on numerical modelling of the behaviour of steel structural elements in case of fire with slender cross-sections. To accurately carry out these analyses it is necessary to take into account those local instability modes, which normally is only possible with shell finite elements. However, aiming at the development of more expeditious methods, particularly important for analysing complete structures in case of fire, recent studies have proposed the use of beam finite elements considering the presence of local buckling through the implementation of a new effective steel constitutive law. The objective of this work is to develop a study to validate this methodology using the program SAFIR. Comparisons are made between the results obtained applying the referred new methodology and finite element analyses using shell elements. The studies were made to laterally restrained beams, unrestrained beams, axially compressed columns and columns subjected to bending plus compression.},

  abstract  = {The refurbishment of old buildings often goes hand in hand with an increase in both the dead and live loads. The latter, combined with the higher safety factors, often make the reinforcement of the old structures necessary. Most reinforcement methods involve transforming a structural timber member into a composite beam. Composite sections have a long tradition in timber construction. In the early days, multiple timber beams were connected with interlocking tooth and wooden shear connecters, which resulted in an elastic connection. Although historical timber structures are frequently upgraded, no method has yet been established and fully accepted by all stakeholders such as owners, builders, architects, engineers and cultural heritage organisations. Carbon fibre-reinforced polymers (CFRP) have already shown their efficiency in structural reinforcement especially in concrete structures. Moreover, previous studies have shown that CFRP has the potential to meet the expectations of all parties involved. In order to reach the service-limit state, a high amount of carbon fibres has to be used, or considering the cost of reinforcement, prestress has to be applied. However, prestressing often goes hand-in-hand with delaminating issues. The camber method presented here offers an efficient solution for prestressing timber bending members and overcoming the known obstacles. In the method proposed, the timber beam is cambered using an adjustable prop at midspan during the bonding of the CRFP-lamella to the lower side of the bending member. After curing the adhesive, the prop is removed and the prestressed composite beam is ready to be used. The prestress introduced in the system is not constant, but has a triangular shape and peaks at midspan, where it is used the most. The prestress force, which declines towards the end of the beam, leads to a constant shear stress over the whole length of the reinforcement,avoiding a concentrated anchorage zone. An analytical calculation model has been developed to calculate and design prestressed timber- bending members using the camber method. Numerical modelling, using a multi-surface plasticity model for timber, confirmed the results from the analytical model, and clearly reduced delaminating issues, comparing very favourably to traditional prestressing methods. The experimental parametric study, including the determination of the short-term loadbearing capacity of structural-sized beams, showed agreement with the analytical and numerical calculation. The prestressed reinforcement showed a benefit of nearly 50\% towards the ultimate-limit state and up to 70\% towards the service-limit state. Calculations revealed that the use of high modulus CFRP allows even higher benefits, depending on the configurations and requirements. The long-term design of the prestressed composite beam was investigated by extending the analytical model. The creep of the timber leads to a load transfer from the timber towards the CFRP, and therefore increases the benefit towards the ultimatelimit design. Applying high modulus CFRP-lamellas allows for a complete utilisation of the design capacity of timber and carbon fibre-reinforced polymer. The thorough investigation conducted demonstrated that the camber method is an efficient technique for prestressing and reinforcing timber-bending members. Furthermore, the calculation model presented allows for a safe design and estimation of long-term behaviour.},

  abstract  = {The main objective of this thesis is to investigate the characteristics of rice husk ash RHA) and then its behaviour in self-compacting high performance concrete (SCHPC) with respects to rheological properties, hydration and microstructure development and alkali silica reaction, in comparison with silica fume (SF). The main results show that the RHA is a macro-mesoporous amorphous siliceous material with a very high silica content comparable with SF. The pore size distribution is the most important parameter of RHA besides amorphous silica content. This parameter affects pore volume, specific surface area, and thus the water demand and the pozzolanic reactivity of RHA and its behaviour in SCHPC. The incorporation of RHA decreases filling and passing abilities, but significantly increases plastic viscosity and segregation resistance of SCHPC. Therefore, RHA can be used as a viscosity modifying admixture for SCHPC. The incorporation of RHA increases the superplasticizer adsorption, the superplasticizer saturation dosage, yield stress and plastic viscosity of mortar. Fresh mortar formulated from SCHPC is a shear-thickening material. The incorporation of RHA/SF ecreases the shearthickening degree. The incorporation of RHA/SF increases the degree of cement hydration. SF appears more effective at 3 days possibly due to the better nucleation site effect, whereas RHA dominates at the later ages possibly due to the internal water curing effect. The incorporation of RHA/SF increases the degree of C3S hydration, particularly the C3S hydration rate from 3 to 14 days. The pozzolanic reaction takes place outside and inside RHA particles. The internal pozzolanic eaction products consolidate the pores inside RHA particles rather than contribute to the pore refinement in the cement matrix. In the presence of the high alkali concentration, RHA particles act as microreactive aggregates and react with alkali hydroxide to generate the expansive alkali silica reaction products. Increasing the particle size and temperature increases the alkali silica reactivity of RHA. The mechanism for the successive pozzolanic and alkali silica reactions of RHA is theorized. Additionally, a new simple mix design method is proposed for SCHPC containing various supplementary cementitious materials, i.e. RHA, SF, fly ash and limestone powder.},

  abstract  = {Some caad packages offer additional support for the optimization of spatial configurations, but the possibilities for applying optimization are usually limited either by the complexity of the data model or by the constraints of the underlying caad system. Since we missed a system that allows to experiment with optimization techniques for the synthesis of spatial configurations, we developed a collection of methods over the past years. This collection is now combined in the presented open source library for computational planning synthesis, called CPlan. The aim of the library is to provide an easy to use programming framework with a flat learning curve for people with basic programming knowledge. It offers an extensible structure that allows to add new customized parts for various purposes. In this paper the existing functionality of the CPlan library is described.},

  abstract  = {In this paper we present some rudiments of a generalized Wiman-Valiron theory in the context of polymonogenic functions. In particular, we analyze the relations between different notions of growth orders and the Taylor coefficients. Our main intention is to look for generalizations of the Lindel¨of-Pringsheim theorem. In contrast to the classical holomorphic and the monogenic setting we only obtain inequality relations in the polymonogenic setting. This is due to the fact that the Almansi-Fischer decomposition of a polymonogenic function consists of different monogenic component functions where each of them can have a totally different kind of asymptotic growth behavior.},

Serving as an interface to radio astronomical databases or being applied to live data from the radio telescopes, the application supports various data filters measuring signal-to-noise ratio (SNR), Doppler's drift, degree of signal localization on celestial sphere and other useful tools for signal extraction and classification. Originally designed for the database of narrow band signals from SETI Institute (setilive.org), the application has been recently extended for the detection of wide band periodic signals, necessary for the search of pulsars. We will also address the detection of week signals possessing arbitrary waveforms and present several data filters suitable for this purpose.},

  abstract  = {Variational formulation of a coupled thermomechanical problem of anisotropic solids for the case of non-isothermal finite deformations in a reference configuration is shown. The formulation of the problem includes: a condition of equilibrium flow of a deformation process in the reference configuration; an equation of a coupled heat conductivity in a variational form, in which an influence of deformation characteristics of a process on the temperature field is taken into account; tensor-linear constitutive relations for a hypoelastic material; kinematic and evolutional relations; initial and boundary conditions. Based on this formulation several axisymmetric isothermal and coupled problems of finite deformations of isotropic and anisotropic bodies are solved. The solution of coupled thermomechanical problems for a hollow cylinder in case of finite deformation showed an essential influence of coupling on distribution of temperature, stresses and strains. The obtained solutions show the development of stressstrain state and temperature changing in axisymmetric bodies in the case of finite deformations.},

  abstract  = {Known as a sophisticated phenomenon in civil engineering problems, soil structure interaction has been under deep investigations in the field of Geotechnics. On the other hand, advent of powerful computers has led to development of numerous numerical methods to deal with this phenomenon, resulting in a wide variety of methods trying to simulate the behavior of the soil stratum. This survey studies two common approaches to model the soil's behavior in a system consisting of a structure with two degrees of freedom, representing a two-storey frame structure made of steel, with the column resting on a pile embedded into sand in laboratory scale. The effect of soil simulation technique on the dynamic behavior of the structure is of major interest in the study. Utilized modeling approaches are the so-called Holistic method, and substitution of soil with respective impedance functions.},

  abstract  = {A central issue for the autonomous navigation of mobile robots is to map unknown environments while simultaneously estimating its position within this map. This chicken-eggproblem is known as simultaneous localization and mapping (SLAM). Asctec's quadrotor Pelican is a powerful and flexible research UAS (unmanned aircraft system) which enables the development of new real-time on-board algorithms for SLAM as well as autonomous navigation. The relative UAS pose estimation for SLAM, usually based on low-cost sensors like inertial measurement units (IMU) and barometers, is known to be affected by high drift rates. In order to significantly reduce these effects, we incorporate additional independent pose estimation techniques using exteroceptive sensors. In this article we present first pose estimation results using a stereo camera setup as well as a laser range finder, individually. Even though these methods fail in few certain configurations we demonstrate their effectiveness and value for the reduction of IMU drift rates and give an outlook for further works towards SLAM.},
