  abstract  = {This paper presents a generic methodology for measurement system configuration when the goal is to identify behaviour models that reasonably explain observations. For such tasks, the best measurement system provides maximum separation between candidate models. In this work, the degree of separation between models is measured using Shannon's Entropy Function. The location and type of measurement devices are chosen such that the entropy of candidate models is greatest. This methodology is tested on a laboratory structure and, to demonstrate generality, an existing fresh water supply network in a city in Switzerland. In both cases, the methodology suggests an appropriate set of sensors for identifying the state of the system.},

The transition (I) is realised by means of a model adaptive concept based on an innovative finite element technology. For transition (II) we apply the truncated balanced realisation method (TBR). The latter represents an established system theoretical model reduction technique which is here combined with a novel substructure technique. The approach provides a modular concept to facilitate the computational analysis of complex structures. The final goal is to apply the strategy to life time estimation.},

  abstract  = {Trotz der weiten Verbreitung erfolgt die Planung der Restbetonrecyclinganlagen immer noch durch learnig-by-doing, da verfahrenstechnisches Grundlagenwissen nicht vorliegt. Wer an verantwortlicher Stelle die Investition in eine neue oder in die Verbesserung einer bestehenden Restbetonrecyclinganlage beurteilen soll, steht vor einer komplexen Entscheidung, die unter Ber{\"u}cksichtigung unterschiedlichster Kriterien getroffen werden muss. In der Praxis besteht hinsichtlich der Qualit{\"a}tssicherung der Recyclingprodukte, der Ablagerungen der noch reaktiven Zementpartikel, der Bemessung der eingesetzten Maschinen, der praktikablen Handhabung hinsichtlich einiger Detailprobleme sowie der Anordnung der verfahrenstechnischen Komponenten in Bezug zur Gel{\"a}ndeoberkante weitgehend Unklarheit. Das allgemeine Verlangen nach einer durchdachten Entscheidungshilfe und die Notwendigkeit, zu einem sachlich begr{\"u}ndeten Urteil zu kommen, macht Entscheidungshilfen f{\"u}r die Planung von Restbetonrecyclinganlagen erforderlich. Insbesondere da Fehlentscheidungen nicht nur mit großem Aufwand r{\"u}ckg{\"a}ngig gemacht werden k{\"o}nnen. Hierf{\"u}r wurden 18 maßgebliche Entscheidungskriterien entwickelt. Diese Entscheidungskriterien wurden im Rahmen der Nutzwertanalyse als Projektziele entwickelt. Die erarbeiteten Kriterien einteilen: - Kriterien zur Qualit{\"a}tssicherung bei der Verwendung der Recyclingprodukte F{\"u}r die Wiederverwendung der Recyclingprodukte Restwasser und Restbetonzu- schlag sind im technischen Regelwerk Verfahrensweisen vorgechrieben. Hinsichtlich der Prozesse bei der Wiederverwendung konnten deutliche Ver- besserungspotentiale aufgezeigt werden. Besonders die Anwendung von online- Dichtemessverfahren im Vergleich zur Ar{\"a}ometermessung verbessert die Len- kungsprozesse zur Qualit{\"a}tssicherung. Aber auch die weitere Klassierung oder das getrennte Lagern und Dosieren des Restbetonzuschlags im Vergleich zu der im technischen Regelwerk vorgeschriebenen Verfahrensweise des volumetrischen Absch{\"a}tzens bringt Verbesserungspotential. - Kriterien zur Minimierung von Ablagerungen Noch reaktive Zementpartikel kommen zeitweise permanent mit Anlagen- komponenten, Leitungen und Beckeninnenfl{\"a}chen der Recyclinganlage in Be- r{\"u}hrung. Ablagerungen von Zementpartikeln, die den Betrieb der Anlage be- hindern, verschlechtern oder sogar verhindern, sind unvermeidbar. Aller- dings kann, wie im Rahmen dieser Arbeit gezeigt wurde, eine Minimierung der Ablagerungen durch geeignete Maßnahmen herbeigef{\"u}hrt werden. Die Ablage- rungen im Suspensionsbeckenlassen sich durch den Zustand der homogenen Suspension sowie durch das Str{\"o}mungsbild angepasste Formgebung minimieren. Durch die geeignete Gef{\"a}llewahl und vor allem durch die korrekte Wahl der Pumpenart k{\"o}nnen die Ablagerungen in Leitungen minimiert werden. - Kriterien zur Bemessung der verfahrenstechnischen Apparate Die Auslegung der Recyclinganlage hinsichtlich der Auswaschleistung, der R{\"u}hrerleistung und der Gr{\"o}ße des Suspendierraumes erfolgt bisher anhand von praktischen Erfahrungswerten. In dieser Arbeit wurde f{\"u}r die Auswasch- leistung ein allgemeing{\"u}ltiges Berechnungsmodel hergeleitet. Dar{\"u}ber hinaus wurde gezeigt, dass die R{\"u}hrerleistung f{\"u}r das Suspendieren von Restwasser berechnet werden kann. Die Gr{\"o}ße des Suspendierraumes kann unter Be- r{\"u}cksichtigung der zu- und abfließenden Materialstr{\"o}me berechnet werden. Das Trennverhalten des mechanischen Klassierers wurde im Rahmen einer Ver- suchsreihe mit folgenden Ergebnissen ermittelt: a. Die Klassierdurchs{\"a}tze steigen mit gr{\"o}ßer werdendem Entleerdurchsatz. ufgrund der Pufferwirkung des mechanischen Klassierers, bei der die diskontinuierlich in den Aufgabetrichter gef{\"u}llte Restbetontr{\"u}be (Ent- leeren) in einem kontinuerlichen Prozess (Klassieren) durch den Trog gef{\"o}rdert wird, n{\"a}hert sich der Klassierdurchsatz asymtotisch einem Grenzwert an. b. Das Masseausbringen rbz wird signifikant vom Klassierdurchsatz und weniger vom Entleerdurchsatz beeinflusst. c. Die Korngr{\"o}ßenverteilung des Restbetons, des Restbetonzuschlags und des Restwassers belegen anschaulich den erreichten Trenneffekt. d. Die Trennkorngr{\"o}ße steigt mit zunehmendem Klassierdurchsatz an. Diese Tendenz ist allerdings nur bei Betrachtung des "nassen" Klassier- durchsatzes signifikant erkennbar. Bei Betrachtung des "trockenen" Durchsatzes ergibt sich keine Abh{\"a}ngigkeit. Die Ursache hierf{\"u}r ist, dass in den "nassen" Durchsatz Prozesse wie Tr{\"u}beagitation und Feinkorn- konzentration indirekt eingehen. e. Der Fehlkornanteil < 125 µm im Restbetonzuschlag steigt ebenfalls mit "nassem" Klassiersatz an. f. Im Unterschied dazu bestehen f{\"u}r den Fehlkornanteil > 125 µm im Rest- wasser signifikante Abh{\"a}ngigkeiten zu Entleer- und Klassierdurchs{\"a}tzen. Ursache ist der tote Fluss. - Kriterien zur Praktikabilit{\"a}t des Anlagenberiebes - Interdependenzen zwischen Anlagenkomponenten},

  abstract  = {Site superintendents performing project management tasks on construction sites need to access project documents and need to collect information that they observe while inspecting the site. Often, information that is observed on a construction site needs to be integrated into electronic documents or project control systems. In the future, we expect integrated product and process models to be the medium for storing and handling construction project management information. Even though mobile computing devices today are already capable of storing and handling such integrated product and process data models, the user interaction with such large and complex models is difficult and not adequately addressed in the existing research. In this paper, we introduce a system that supports project management tasks on construction sites effectively and efficiently by making integrated product and process models accessible. In order to effectively and efficiently enter or access information, site superintendents need visual representations of the project data that are flexible with respect to the level of detail, the decomposition structure, and the type of visual representation. Based on this understanding of the information and data collection needs, we developed the navigational model framework and the application Site Data Collection System (SiDaCoS), which implements that framework. The navigational model framework allows site superintendents to create customized representations of information contained in a product and process model that correspond to their data access and data collection needs on site.},

  abstract  = {Building activities in the construction industry in Germany increasingly concentrate on building measures in or involving the existing built environment. Before planning can begin, buildings must be surveyed in whole or in part with the surveying of geometric data playing a dominant role. The geometric survey is typically undertaken using geodetic or photogrammetric measuring techniques and equipment that have been adapted for use in building surveying. Accordingly appropriate technical knowledge is required in order to be able to operate them as well as a considerable financial investment. Such equipment and surveying methods are usually adaptations from other disciplines. The paper discusses and presents approaches to developing "new" equipment for building surveying, devised with the needs of building surveying in mind - redesigns or new designs for surveying tools. The designs are the result of an inter-disciplinary project between the Faculty of Architecture and the Faculty of Product Design at the Bauhaus Universit{\"a}t Weimar.},

These investigative tasks are often related with a great effort concerning time and money, because there are no standardized workflows and interfaces which provide an efficient access to the necessary information related to a specific construction site. Within the fundamental investigation human and natural circumstances have to be taken into account. Thus, in this project two examples have been chosen in order to demonstrate the holistic approach for an integration and provision of georeferenced information. The developed internet-site http://www.grundlagenermittlung.de has been designed to support architects and civil engineers in early planning phases of a building project efficiently. It offers web-based services based on dynamic interfaces for a flexible search and collection of information concerning the building site. Therefore, a central Metadatabase-Server for Description, Discovery and Integration has been established which enables a registration of georeferenced services and the redirection of incoming requests to other, distributed data pools. Using this Yellow-Page concept in combination with the underlying meta-data based on the ISO 19115 standard an efficient investigation of geographical and environmental information becomes possible.},

This aim can be only reached by transferring of innovative information and communication technologies in the field of cooperation of all partners in a building project. In this article the enhancement of the existing planning processes based on an improved information management is introduced. Since the late 90ies the availability of hardware and software infrastructures for a networkbased cooperation, e.g. email, in small and middle-sized companies increased the problems of an unstructured communication in the planning and construction processes. These problems have not been solved by the usage of the upcoming project communication systems either, which are often used as a simple medium for data transfer. Because of the easy way of distributing documents to all planning partners a huge amount of files and subsequent versions can be stored so that the planners often have to scope with an information overflow. The underlying hierarchical structures based on simple files stored in tree views are not sufficient for an adequate representation of the different specific views of the planners and the management of relationships between the three information domains building structure, costs and time schedules. ..},

Weiterhin stimmen die lokalen Gr{\"o}ßen W{\"a}rme{\"u}bergangskoeffizient, Erdoberfl{\"a}chentemperatur, Lufttemperatur und Glasdachtemperatur gut zwischen den Modellen {\"u}berein. Mit dem CFD Modell wurden der Prototyp und 3 Großkraftwerke berechnet. Mit dem entwickelten instation{\"a}ren FDM-Modell wurden erstmalig numerische Langzeitsimulationen (1 Jahr) durchgef{\"u}hrt. Zur {\"U}berpr{\"u}fung des Modells wurden die Ergebnisse mit Messwerten aus Manzanares verglichen, wobei eine gute {\"U}bereinstimmung erreicht werden konnte. Das Verst{\"a}ndnis f{\"u}r die stattfindenden thermodynamischen und str{\"o}mungsmechanischen Prozesse in einem Aufwindkraftwerk konnte durch die Arbeit maßgeblich verbessert werden.},

  abstract  = {The paper describes further developments of the interactive evolutionary design concept relating to the emergence of mutually inclusive regions of high performance design solutions. These solutions are generated from cluster-oriented genetic algorithm (COGAs) output and relate to a number of objectives introduced during the preliminary design of military airframes. The data-mining of multi-objective COGA (moCOGA) output further defines these regions through the application of clustering algorithms, data reduction and variable attribute relevance analyses. A number of visual representations of the COGA output projected onto both variable and objective space are presented. The multi-objective output of the COGA is compared to output from a Strength Pareto Evolutionary Algorithm (SPEA-II) to illustrate the manner in which moCOGAs can generate good approximations to Pareto frontiers.},

  abstract  = {The engineering and construction industry has been slow to exploit the full potential of information technology. The industry is highly fragmented, price sensitive, risk-adverse, and profit margins are small. Each project is unique with a small amount of technological innovation opportunities to capitalise on from one project to the next. Technological innovations that have been taking place are just simulating the old traditional paper workflow. Engineering information in digital form is being conveyed using traditional paper representations, which have to be interpreted by humans before the information can be used in other applications, thereby creating 'islands of information'. It can be seen that poorly implemented IT strategies are duplicating paperwork, rather than reducing or eliminating it (Crowley et al., 2000). This paper will introduce the Integrated Engineering Workflow (IEW) concept to re-organise a structural discipline working on multi-disciplinary projects so as to maximise the advantages offered by new information technology.},
