This notion emerges in the epistemic break that takes place around 1800 and that entails the opening up of the notion of biopolitics under the name of governmentality, implying that life is not only the object of biopolitics but also serves as its model.}, subject = {Biopolitik}, language = {es} } @article{WangArash, author = {Wang, Quan and Arash, Behrouz}, title = {Announcement of a virtual special issue on computational carbon nanoscience}, series = {Carbon}, journal = {Carbon}, doi = {10.1016/j.carbon.2015.05.082}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20170428-31695}, pages = {370 -- 372}, abstract = {The Carbon journal is pleased to introduce a themed collection of recent articles in the area of computational carbon nanoscience.

Recent behavioral and neuroimaging studies reported that self-face identification not only relies upon visual-mnemonic representation of ones own face but also upon continuous updating and integration of visuo-tactile signals. Therefore, bodily self-consciousness plays a major role in self-face identification, with respect to interplay between unisensory and multisensory processing. However, if previous studies demonstrated that the integration of multisensory body-related signals contributes to the visual processing of ones own face, there is so far no data regarding how self-face identification, inversely, contributes to bodily self-consciousness. In the present study, we tested whether selfother face identification impacts either the egocentered or heterocentered visuo-spatial mechanisms that are core processes of bodily self-consciousness and sustain selfother distinction. For that, we developed a new paradigm, named Double Mirror. This paradigm, consisting of a semi-transparent double mirror and computer-controlled Light Emitting Diodes, elicits selfother face merging illusory effect in ecologically more valid conditions, i.e., when participants are physically facing each other and interacting. Self-face identification was manipulated by exposing pairs of participants to an Interpersonal Visual Stimulation in which the reflection of their faces merged in the mirror. Participants simultaneously performed visuo-spatial and mental own-body transformation tasks centered on their own face (egocentered) or the face of their partner (heterocentered) in the pre- and post-stimulation phase. We show that selfother face identification altered the egocentered visuo-spatial mechanisms. Heterocentered coding was preserved.

Semianalytical formulations are contemporary mathematical models which currently becoming available for realization due to substantial speed-up of computer productivity. DCBEM is based on the theory of the pseudodifferential boundary equations. Corresponding pseudodifferential operators are discretely approximated using Fourier analysis or wavelet analysis. The main DCBEM advantages against the other methods of the numerical analysis is a double reduction in dimension of the problem (discrete numerical division applied not to the full region of the interest but only to the boundary of the region cross section, as a matter of fact one is solving an one-dimensional problem with the finite step on the boundary area of the region), one has opportunities to carrying out very detailed analysis of the specific chosen zones, simplified initial data preparation, simplistic and adaptive algorithms. There are two methods to define and conduct DCBEM analysis developed - indirect (IDCBEM) and direct (DDCBEM), thus indirect like in boundary element method (BEM) applied and used little bit more than direct.}, subject = {Architektur }, language = {en} } @inproceedings{ZimmermannBartels, author = {Zimmermann, J{\"u}rgen and Bartels, Jan-Hendrik}, title = {TREE-BASED METHODS FOR RESOURCE INVESTMENT AND RESOURCE LEVELLING PROBLEMS}, editor = {G{\"u}rlebeck, Klaus and K{\"o}nke, Carsten}, organization = {Bauhaus-Universit{\"a}t Weimar}, doi = {10.25643/bauhaus-universitaet.3040}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20170327-30405}, pages = {6}, abstract = {The execution of project activities generally requires the use of (renewable) resources like machines, equipment or manpower.

The 2D spherical harmonics are employed as basis functions to construct the algebraically extended 2D image representation. From this representation, the monogenic signal and the monogenic curvature signal for modeling intrinsically one and two dimensional (i1D/i2D) structures are obtained as special cases.

At first, for each single picture the 3D position of the reference quadrangle (with respect to each camera coordinate frame) is calculated.

The nonlinear behaviour of masonry can be modelled using concepts of damage theory.

Usually it is difficult to evaluate the number of users because it depends on human factor and data in the considered system are uncertain. In such situation the traditional mathematical approaches can not take into consideration rough data. Therefore a fuzzy approach can be applied in this case. A fuzzy methodology is treated as a proper way to describe choice of mode of transport, and especially that uncertainty accompanied of choosing process has rather fuzzy character. The proposed approach is based on the Mamdani Fuzzy Inference System and for calculation there is used Matlab software with Fuzzy Logic Toolbox. Mamdani model requires, as an input data, knowledge of the shape of membership function. These functions can be calibrated taking into consideration results of questionnaires conducted among users of Park and Ride system. Due to lack of representative sample of users, one has decided to use results of experts' questionnaires as a input data for calibration the shape of membership functions. Describing factor will be generalized cost of the trip for different modes of transport. Proposed approach consists of two main stages: modeling of share of public/private transport trips and Multimodal model estimating number of Park and Ride users. Verification of presented methodology is treated as an indirect proof. Proposed approach can be applied for estimation of bi-modal split. Then the results are compared with traditional approaches based on logit functions.

The sensitivity is presented in the form of the probability distribution of the limit state of the structure. The analysis is performed by the problem-oriented Monte Carlo simulation procedure. The procedure is based on the problem's definition of the elementary event, as a structural limit state. Thus the sample space consists of limit states of the structure. Defined on the sample space the one-dimensional random multiplier is introduced. This multiplier refers to the dominant basic variable (group of variables) of the problem. Numerical procedure results in the set of random numbers. Normalized relative histogram of this set is an estimator of the PDF of the limit state of the structure. Estimators of reliability, or the probability of failure are statistical characteristics of this histogram. The procedure is illustrated by the example of sensitivity analysis of the serviceability limit state of monumental structure. It is the colonnade of Licheń Basilica, situated in central Poland. Limit state of the structure is examined with reference to the upper deck horizontal deflection. Wind actions are taken as dominant variables. An assumption is made that the wind load intensities acting on the lower and on the upper storey of the colonnade, respectively, are identically distributed, but correlated random variables. Three correlation variants of these variables are considered. Relevant limit state histograms are analysed thereafter.

The former is based on bending moment distribution in the considered member, the latter one - on the member rotation at the given joint. 2D-element model of finite element method is described: webs and flanges are modeled with shell elements, while rivets in the connection - with system of beam and spring elements. The method of rivet modeling is verified by T-stub connection test results published in literature. FEM analyses proved that recorded extent of corrosion damage does not alter the initial rotational restraint of stringer-to-crossbeam connection. Strengthening of stringer midspan influences midspan bending moment and stringer end rotation in a different way.

Einer der ersten Systemanwendungen dieses offenen Infrastrukturkonzepts ist die integrierte Systembedienung mit zum Teil v{\"o}llig neuen Bedienkonzepten und einer starken Bedienungsvereinfachung auch komplexester Technikausr{\"u}stungen in Immobilien. Der Beitrag beschreibt nach einer Analyse der Ausgangslage die technologischen Grundz{\"u}ge der integrierten Systembedienung. Es folgen einige Anwendungsbeispiele und eine zusammenfassende Bewertung mit einem Ausblick auf weiterf{\"u}hrende Aktivit{\"a}ten.}, subject = {Architektur }, language = {de} } @inproceedings{SchapkeSchererKatranuschkov, author = {Schapke, Sven-Eric and Scherer, Raimar J. and Katranuschkov, Peter}, title = {SEMANTIC SERVICE ENVIRONMENTS FOR INTEGRATING TEXT WITH MODEL-BASED INFORMATION IN AEC/FM}, editor = {G{\"u}rlebeck, Klaus and K{\"o}nke, Carsten}, organization = {Bauhaus-Universit{\"a}t Weimar}, doi = {10.25643/bauhaus-universitaet.3012}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20170327-30125}, pages = {10}, abstract = {In distributed project organisations and collaboration there is a need for integrating unstructured self-contained text information with structured project data. We consider this a process of text integration in which various text technologies can be used to externalise text content and consolidate it into structured information or flexibly interlink it with corresponding information bases. However, the effectiveness of text technologies and the potentials of text integration greatly vary with the type of documents, the project setup and the available background knowledge. The goal of our research is to establish text technologies within collaboration environments to allow for (a) flexibly combining appropriate text and data management technologies, (b) utilising available context information and (c) the sharing of text information in accordance to the most critical integration tasks. A particular focus is on Semantic Service Environments that leverage on Web service and Semantic Web technologies and adequately support the required systems integration and parallel processing of semi-structured and structured information. The paper presents an architecture for text integration that extends Semantic Service Environments with two types of integration services. Backbone to the Information Resource Sharing and Integration Service is a shared environment ontology that consolidates information on the project context and the available model, text and general linguistic resources. It also allows for the configuration of Semantic Text Analysis and Annotation Services to analyse the text documents as well as for capturing the discovered text information and sharing it through semantic notification and retrieval engines. A particular focus of the paper is the definition of the overall integration process configuring a complementary set of analyses and information sharing components.}, subject = {Architektur }, language = {en} } @inproceedings{SampaioHenriquesStuderetal., author = {Sampaio, Alcinia Zita and Henriques, Pedro and Studer, P. and Luizi, Rui}, title = {VIRTUAL REALITY TECHNOLOGY TO REPRESENT CONSTRUCTION ACTIVITIES}, editor = {G{\"u}rlebeck, Klaus and K{\"o}nke, Carsten}, organization = {Bauhaus-Universit{\"a}t Weimar}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20170327-30090}, pages = {9}, abstract = {The use of virtual reality techniques in the development of educational applications brings new perspectives to the teaching of subjects related to the field of civil construction in Civil Engineering domain. In order to obtain models, which would be able to visually simulate the construction process of two types of construction work, the research turned to the techniques of geometric modelling and virtual reality. The applications developed for this purpose are concerned with the construction of a cavity wall and a bridge. These models make it possible to view the physical evolution of the work, to follow the planned construction sequence and to visualize details of the form of every component of the works. They also support the study of the type and method of operation of the equipment necessary for these construction procedures. These models have been used to distinct advantage as educational aids in first-degree courses in Civil Engineering. Normally, three-dimensional geometric models, which are used to present architectural and engineering works, show only their final form, not allowing the observation of their physical evolution. The visual simulation of the construction process needs to be able to produce changes to the geometry of the project dynamically. In the present study, two engineering construction work models were created, from which it was possible to obtain three-dimensional models corresponding to different states of their form, simulating distinct stages in their construction. Virtual reality technology was applied to the 3D models. Virtual reality capacities allow the interactive real-time viewing of 3D building models and facilitate the process of visualizing, evaluating and communicating.}, subject = {Architektur }, language = {en} } @inproceedings{RyanKrausshar, author = {Ryan, John and Kraußhar, Rolf S{\"o}ren}, title = {ANALYSIS OF DIRAC OPERATORS ON SOME CONFORMALLY FLAT MANIFOLDS}, editor = {G{\"u}rlebeck, Klaus and K{\"o}nke, Carsten}, organization = {Bauhaus-Universit{\"a}t Weimar}, doi = {10.25643/bauhaus-universitaet.3008}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20170327-30081}, pages = {5}, abstract = {In this paper we shall review the role of Dirac operators arising in Clifford analysis over some examples of conformally flat manifolds.}, subject = {Architektur }, language = {en} } @inproceedings{RueppelMeissnerLange, author = {R{\"u}ppel, Uwe and Meißner, Udo F. and Lange, Michael}, title = {KOOPERATIVE BRANDSCHUTZPLANUNG MIT SOFTWARE-AGENTEN}, editor = {G{\"u}rlebeck, Klaus and K{\"o}nke, Carsten}, organization = {Bauhaus-Universit{\"a}t Weimar}, doi = {10.25643/bauhaus-universitaet.3007}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20170327-30071}, pages = {10}, abstract = {Die effektive Kooperation aller beteiligten Fachplaner im Bauplanungsprozess ist die Voraussetzung f{\"u}r wirtschaftliches und qualitativ hochwertiges Bauen. Bauprojektorganisationen bestehen in der Regel aus zahlreichen unabh{\"a}ngigen Planungspartnern, die {\"o}rtlich verteilt spezifische Planungsaufgaben bearbeiten und die Ergebnisse in Teilproduktmodellen ablegen. Da Planungsprozesse im Bauwesen stark arbeitsteilig ablaufen, sind die Teilproduktmodelle der einzelnen Fachplanungen in hohem Maße voneinander abh{\"a}ngig. Ziel des hier vorgestellten Ansatzes ist die Integration der Teilproduktmodelle der Geb{\"a}udeplanung in einem netzwerkbasierten Modellverbund am Beispiel der Brandschutzplanung. Im Beitrag werden die Probleme der Verteiltheit und insbesondere der semantischen Heterogenit{\"a}t der involvierten Teilproduktmodelle betrachtet. Der verteilte Zugriff wird mithilfe mobiler Software-Agenten realisiert. Die Agenten k{\"o}nnen sich dabei frei im netzwerkbasierten Planungsverbund bewegen und agieren als Vertreter der Fachplaner. Das Problem der semantischen Heterogenit{\"a}t der Teilproduktmodelle wird auf der Basis von Ontologien gel{\"o}st. Dazu werden erstens Dom{\"a}nenontologien entwickelt, die Objekte der realen Welt einer abgeschlossenen Dom{\"a}ne, hier des Brandschutzes, abbilden. Zweitens werden Applikationsontologien entwickelt, die die einzelnen propriet{\"a}ren Datenhaltungen (im Sinne von Teilproduktmodellen) der jeweiligen Fachplanungen repr{\"a}sentieren. Beide Ontologien werden mit einem regelbasierten Ansatz verkn{\"u}pft. Im vorgestellten Anwendungsfall Brandschutz dient die Dom{\"a}nenontologie als einheitliche Schnittstelle f{\"u}r den Zugriff auf die verteilten Modelle und abstrahiert dabei von deren Datenbankspezifika und propriet{\"a}ren Schemata. Mithilfe von mobilen Agenten und semantischen Technologien kann so eine Plattform zur Verf{\"u}gung gestellt werden, die erstens die dynamische Integration von Ressourcen in den Planungsverbund erlaubt und zweitens auf deren Basis unabh{\"a}ngig von der Verteiltheit und Heterogenit{\"a}t der eingebundenen Ressourcen ingenieurgerechte Verarbeitungsmethoden realisiert werden k{\"o}nnen.}, subject = {Architektur }, language = {de} } @inproceedings{Rohr, author = {Rohr, Stefan}, title = {NEUE M{\"O}GLICHKEITEN IN DER ABLAUFPLANUNG DURCH DIE EREIGNISORIENTIERTE SIMULATION VON PRODUKTIONSPROZESSEN}, editor = {G{\"u}rlebeck, Klaus and K{\"o}nke, Carsten}, organization = {Bauhaus-Universit{\"a}t Weimar}, doi = {10.25643/bauhaus-universitaet.3006}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20170327-30060}, pages = {63}, abstract = {Durch die Betrachtung des Produktions-Prozesses als zentrales Transformationselement wird die Struktur der Bauproduktion realit{\"a}tsnah gefasst.
