description: Extreme weather events lead transportation systems to critical situations, which imply high social, economical and environmental costs. Developing a tool to quantify the damage suffered by a traffic network and its capacity of response to these phenomena is essential to reduce the damage of this hazard and to improve the system. With this aim, a statistical analysis of the resilience of a traffic network under extreme climatological events is presented. The resilience of a traffic network is determined by means of a dynamic restricted equilibrium model together with a travel cost function that includes the effect of weather on a traffic network. The cost function parameters related to the hazard effect are assumed as random, following Generalized Beta distributions. Then, the fragility curves of the target traffic network are defined using the Monte Carlo method and Latin Hypercube sampling. Fragility curves are a useful tool to analyse of the vulnerability of a traffic network, assisting in the decision-making for the prevention and response to the extreme weather events.

description: Using the Varieties of Democracy (V-Dem) dataset version 15, we offer six main findings about contemporary trends of regime transformations. First, the average level of liberal democracy continues to decline, and is back to 1985-level by population-weighted averages. Second, freedom of expression is worsening in nearly a quarter of all countries in the world, setting a new absolute record during the last 25 years. Third, 45 countries are in ongoing episodes of autocratization, and 19 countries are in ongoing episodes of democratization. Fourth, almost half of all autocratizing countries are increasingly spreading disinformation, and a quarter of all countries are affected by increasing political polarization. Fifth, we launch a watchlist initiative – an approach to detect early signs of autocratization and democratization. Sixth, we provide qualitative evidence of ongoing executive aggrandizement in the USA under the first two months of the second Trump administration. We argue that the USA could become the fastest autocratizing country in contemporary history that does not involve a coup d'état and that the second Trump administration has already taken American democracy closer to a democratic breakdown.

description: Das Aufwindkraftwerk ist eine thermo- hydrodynamische Maschine zur Elektroenergiegewinnung, bestehend aus einem Treibhaus, einem Kamin und einer oder mehreren Turbinen. In dieser Studie wurden numerische Ergebnisse zum thermischen Strömungsverhalten in einem Aufwindkraftwerk unter der Berücksichtigung der Teilmodelle Erdboden, Kollektor, Atmosphäre, Umlenkung, Kamin und Turbine erhaltenden. Hierzu wurden die stationären Grundgleichungen der Thermofluiddynamik auf strukturierten, körperangepassten und rotationssymmetrischen Gittern unter Beachtung aller Rand- und Kopplungsbedingungen numerisch mit dem finite Volumenverfahren gelöst. Besonderes Augenmerk wurde dabei auf die Kalibrierung des Modells im Ruhezustand, auf die numerische Simulation, auf den Einfluss der Strahlung, auf die Betrachtung der Turbine, auf das Dichtemodell sowie auf den turbulenten Strömungszustand gelegt. Die erhaltenen Ergebnisse werden durch Approximationen 2. Ordnung, Gitterunabhängigkeit und durch einen sehr geringen Abbruchfehler charakterisiert. Für 4 verschiedene Einstrahlungen wurden die Verläufe von Temperatur und Geschwindigkeit im Aufwindkraftwerk erhalten. Zusätzlich sind für Vergleichszwecke der Massenstrom, der Temperaturhub, die Leistung an der Turbine und der Wirkungsgrad der Anlage bestimmt wurden. Aufbauend auf den Berechnungen in dieser Arbeit und den numerischen und analytischen Berechnungen in [1] können nun erweiterte Parameterstudien und instationäre Simulationen zum Aufwindkraftwerk durchgeführt werden.

description: We construct a tight-binding model of [(C$_2$H$_5$)$_3$NH]$_2$Cu$_2$(C$_2$O$_4$)$_3$ from Wannier orbital overlaps. Including interactions within the Jahn-Teller distorted Cu-centered $e_g$ Wannier orbitals leads to an effective Heisenberg model. The hyper-honeycomb lattice contains two symmetry distinct sublattices of Cu atoms arranged in coupled chains. One sublattice is strongly dimerized, the other forms isotropic antiferromagnetic chains. Integrating out the strongest (intradimer) exchange interactions leaves extremely weakly coupled Heisenberg chains, consistent with the observed low temperature physics.

description: We consider the Stieltjes moment problem for the Berg-Urbanik semigroups which form a class of multiplicative convolution semigroups on $\mathbb{R}_+$ that is in bijection with the set of Bernstein functions. Berg and Durán proved that the law of such semigroups is moment determinate (at least) up to time $t=2$, and, for the Bernstein function $ϕ(u)=u$, Berg made the striking observation that for time $t>2$ the law of this semigroup is moment indeterminate. We extend these works by estimating the threshold time $\scr{T}_ϕ\in [2,\infty]$ that it takes for the law of such Berg-Urbanik semigroups to transition from moment determinacy to moment indeterminacy in terms of simple properties of the underlying Bernstein function $ϕ$, such as its Blumenthal-Getoor index. One of the several strategies we implement to deal with the different cases relies on a non-classical Abelian type criterion for the moment problem, recently proved by the authors. To implement this approach we provide detailed information regarding distributional properties of the semigroup such as existence and smoothness of a density, and, the large asymptotic behavior for all $t > 0$ of this density along with its successive derivatives. In particular, these results, which are original in the Lévy processes literature, may be of independent interests.

description: A model for the risk assessment of spent nuclear fuel ponds subject to the risk of flooding is proposed. The methodology adopted is based on the enhancement of Bayesian Networks approach with Structural Reliability Methods, in order to overcome the limitations of classic Bayesian Networks (such as the use of only discrete variables in case of exact inference calculations). The computational tool developed for the methodology mentioned is briefly described together with the application to a real-case study. The related results are discussed and compared to those previously obtained by traditional Bayesian Network analysis. Finally, a brief discussion about the advantages and drawbacks of the approach adopted is provided.

description: Self-testing refers to the possibility of characterizing an unknown quantum device based only on the observed statistics. Here we develop methods for self-testing entangled quantum measurements, a key element for quantum networks. Our approach is based on the natural assumption that separated physical sources in a network should be considered independent. This provides a natural formulation of the problem of certifying entangled measurements. Considering the setup of entanglement swapping, we derive a robust self-test for the Bell-state measurement, tolerating noise levels up to 5%. We also discuss generalizations to other entangled measurements.

OBJECTIVE: The goal of this work was to methodically evaluate, optimize, and validate a self-supervised machine learning algorithm capable of real-time automatic registration and fluoroscopic localization of the spine using a single radiograph or fluoroscopic frame. METHODS: The authors propose a two-dimensional to three-dimensional (2D-3D) registration algorithm that maximizes an image similarity metric between radiographic images to identify the position of a C-arm relative to a 3D volume. This work utilizes digitally reconstructed radiographs (DRRs), which are synthetic radiographic images generated by simulating the x-ray projections as they would pass through a CT volume. To evaluate the algorithm, the authors used cone-beam CT data for 127 patients obtained from an open-source de-identified registry of cervical, thoracic, and lumbar scans. They systematically evaluated and tuned the algorithm, then quantified the convergence rate of the model by simulating C-arm registrations with 80 randomly simulated DRRs for each CT volume. The endpoints of this study were time to convergence, accuracy of convergence for each of the C-arm's degrees of freedom, and overall registration accuracy based on a voxel-by-voxel measurement. RESULTS: A total of 10,160 unique radiographic images were simulated from 127 CT scans. The algorithm successfully converged to the correct solution 82% of the time with an average of 1.96 seconds of computation. The radiographic images for which the algorithm converged to the solution demonstrated 99.9% registration accuracy despite utilizing only single-precision computation for speed. The algorithm was found to be optimized for convergence when the search space was limited to a ± 45° offset in the right anterior oblique/left anterior oblique, cranial/caudal, and receiver rotation angles with the radiographic isocenter contained within 8000 cm3 of the volumetric center of the CT volume. CONCLUSIONS: The investigated machine learning algorithm has the potential to aid surgeons in level localization, surgical planning, and intraoperative navigation through a completely automated 2D-3D registration process. Future work will focus on algorithmic optimizations to improve the convergence rate and speed profile.

description: By providing instances of approximation of linear diffusions by birth-death processes, Feller [13], has offered an original path from the discrete world to the continuous one. In this paper, by identifying an intertwining relationship between squared Bessel processes and some linear birth-death processes, we show that this connection is in fact more intimate and goes in the two directions. As by-products, we identify some properties enjoyed by the birth-death family that are inherited from squared Bessel processes. For instance, these include a discrete self-similarity property and a discrete analogue of the beta-gamma algebra. We proceed by explaining that the same gateway identity also holds for the corresponding ergodic Laguerre semi-groups. It follows again that the continuous and discrete versions are more closely related than thought before, and this enables to pass information from one semi-group to the other one.

Im internationalen Zentrum für Bauinformatik hat der Autor die Besonderheiten des Bauwesens formuliert und gefolgert, dass es genügt, in den Klassen topologische, geometrische und graphische Aspekte der Bauobjekte, sowie einige Hilfsbegriffe zu beschreiben. Ein Hauptziel bei der Entwicklung einer Sprache ist die Einfachheit des Schemas. Insgesamt werden etwa nur 50 Klassen für CAD-Systeme vorgeschlagen. In Modellen von Bauobjekten, die von CAD-Systemen erzeugt werden, betrifft der größte Anteil der Daten die geometrische Form der Elemente und ihre Raumlage. Zur Beschreibung der Bauobjekte werden nur 7 Hauptklassen verwendet: Entity, System, Clone, Context, Annotation, Figure und Process. Von besonderer Bedeutung ist die Klasse >Clone<. Sie erlaubt in kompakter Form die Beschreibung einer Menge ähnlicher Objekte, die sich in wenigen Parametern (zum Beispiel, der Lage im Raum) unterscheiden. Das vorgestellte Konzept führt zu einer starken Verringerung der Dateigröße und erleichtert das Erkennen der Objekte bei der Übergabe der Daten. Die Strukturdiagramme der Klassen wurden mit Hilfe der UML-Sprache erzeugt. Die Klassen sind auch im XML-Format beschreiben und können auf Homepage >http://www.mtu-net.ru/pavlov/bodXML< gelesen werden.

description: Autonomous drones are becoming increasingly crucial in a variety of applications, with a particular focus onenvironmental monitoring and disaster management. These unmanned aerial vehicles (UAVs) are revolutionizing the way weapproach environmental challenges by providing real-time data collection, efficient mapping, and analysis of ecosystems that are difficult or hazardous to access. This paper explores the potential of autonomous drones in enhancing environmental monitoring efforts, addressing environmental issues such as climate change, deforestation, and wildlife tracking. Additionally, the paper investigates the role of drones in disaster management, particularly in emergency response, damage assessment, and recoveryefforts after natural disasters. With their ability to cover large areas quickly and collect high-resolution data, autonomous dronesare positioned to play a key role in shaping future strategies for disaster preparedness and environmental sustainability. Thepaper also examines the technological advancements driving this transformation, the challenges associated with dronedeployment, and the future potential of drones in these critical fields.

The Materials Genome Initiative (MGI) is accelerating the pace of advanced materials development by integrating high‐throughput experimentation, database construction, and intelligence computation. Live‐cell imaging agents, such as fluorescent dyes, are exemplary candidates for MGI applications for two reasons: i) they are essential in visualizing cellular structures and functional processes, and ii) the unclear relationship between the chemical structure of fluorescent dyes and their live‐cell imaging properties severely restricts the current trial‐and‐error dye development. Herein, the MGI is followed to present an intelligent combinatorial methodology for predicting the staining cell ability of dyes utilizing machine learning (ML) driven by a structurally diverse combinatorial library. This study demonstrates how to high‐throughput synthesize 1,536 dyes and evaluate their imaging properties to establish a feature dataset for ML. A set of high‐precision ML‐predictors is then successfully modeled for assisting live‐cell staining and endoplasmic reticulum judgment. This approach is believed to bridge the gap between dye structure and corresponding staining behavior, and can accelerate the discovery of novel organelle‐specific stains.

description: This paper is devoted to extend some Hu-Keel results on Mori dream spaces (MDS) beyond the projective setup. Namely, $\Q$-factorial algebraic varieties with finitely generated class group and Cox ring, here called \emph{weak} Mori dream spaces (wMDS), are considered. Conditions guaranteeing the existence of a neat embedding of a (completion of a) wMDS into a complete toric variety are studied, showing that, on the one hand, those which are complete and admitting low Picard number are always projective, hence Mori dream spaces in the sense of Hu-Keel. On the other hand, an example of a wMDS does not admitting any neat embedded \emph{sharp} completion (i.e. Picard number preserving) into a complete toric variety is given, on the contrary of what Hu and Keel exhibited for a MDS. Moreover, termination of the Mori minimal model program (MMP) for every divisor and a classification of rational contractions for a complete wMDS are studied, obtaining analogous conclusions as for a MDS. Finally, we give a characterization of a wMDS arising from a small $\Q$-factorial modification of a projective weak $\Q$-Fano variety.

Background Naming a newly discovered disease is a difficult process; in the context of the COVID-19 pandemic and the existence of post-acute sequelae of SARS-CoV-2 infection (PASC), which includes long COVID, it has proven especially challenging. Disease definitions and assignment of a diagnosis code are often asynchronous and iterative. The clinical definition and our understanding of the underlying mechanisms of long COVID are still in flux, and the deployment of an ICD-10-CM code for long COVID in the USA took nearly 2 years after patients had begun to describe their condition. Here, we leverage the largest publicly available HIPAA-limited dataset about patients with COVID-19 in the US to examine the heterogeneity of adoption and use of U09.9, the ICD-10-CM code for “Post COVID-19 condition, unspecified.”MethodsWe undertook a number of analyses to characterize the N3C population with a U09.9 diagnosis code (n = 33,782), including assessing person-level demographics and a number of area-level social determinants of health; diagnoses commonly co-occurring with U09.9, clustered using the Louvain algorithm; and quantifying medications and procedures recorded within 60 days of U09.9 diagnosis. We stratified all analyses by age group in order to discern differing patterns of care across the lifespan.ResultsWe established the diagnoses most commonly co-occurring with U09.9 and algorithmically clustered them into four major categories: cardiopulmonary, neurological, gastrointestinal, and comorbid conditions. Importantly, we discovered that the population of patients diagnosed with U09.9 is demographically skewed toward female, White, non-Hispanic individuals, as well as individuals living in areas with low poverty and low unemployment. Our results also include a characterization of common procedures and medications associated with U09.9-coded patients.ConclusionsThis work offers insight into potential subtypes and current practice patterns around long COVID and speaks to the existence of disparities in the diagnosis of patients with long COVID. This latter finding in particular requires further research and urgent remediation.

description:
All newborns experience low blood glucose levels when they first initiate carbohydrate metabolism. Some levels remain low, with potential seizures and severe brain injury. Predicting newborns at higher risk is clinically useful because newborns can have their blood sugar raised with breastfeeding, donor milk, formula, or oral dextrose gels. Additionally, informing parents of this higher risk can enhance shared decision-making in the first 48 hours after birth. To address this, we propose three predictive models using binary logistic regression for newborns receiving treatment with oral dextrose gels for hypoglycemia. The first is a parsimonious model, where a high-risk newborn's first blood glucose value is highly predictive of requiring an oral dextrose gel treatment. The second model can be used earlier in the clinical workflow. It is based on the most predictive variables that are also electronically available for all newborns and do not change much in the electronic health record. The third model explores the most predictive variables based on a conceptual model of factors associated with health disparities. These three models are informed from insights gleaned by an exploratory analysis of alternative outcome measures, variables, and threshold cutoffs using a standard heuristic of greedily finding the highest average difference for records on both sides of partitions. We discuss how the dynamics of when data are available during a hospital stay in the postnatal care unit for all patients impact the selection of useful variables for electronically-based decision support. We plan to modify handouts for postnatal care nurses that detail treatment guidance and support shared decision-making. We plan to embed stratified guidance, recommended scripts for high and low-risk cohorts, orientation materials for float and junior nurses, and patient-facing educational materials.

We use the Foldy--Wouthuysen (unitary) transformation of the Dirac operator and its realization as an elliptic problem in the 4-dim half space $\mathbb{R}^4_{+}$ with Neumann boundary condition.

Local measures of disruption for quantifying seismic risk and reliability of complex networks

Publisher: name: The University of British Columbia
Year: 2015

description: This paper presents a study of seismic risk to a complex transportation system while quantifying disruption at the local level. The San Francisco Bay Area transportation system is considered as a case study. The network consists of 32,858 road segments, 3152 bridges subject to damage, and 43 transit modes. A refined model of this network’s performance under damage, incorporating features such as transportation mode choice and dynamic demand, is used to predict disruption. Disruption is caused by earthquake shaking, where a full suite of earthquake scenarios in the region (with associated occurrence rates) are considered in order to obtain a fully probabilistic description of risk. Several strategies to manage the computational cost of this analysis are discussed. A number of network performance metrics are presented to provide insight into the disruption risks faced by residents of the region. Mode-destination accessibility, a metric based on network users’ utility functions, is used here as a limit state to evaluate the potential disruption to individual users of the transportation system as it is a performance metric of interest to urban planners. Additionally, local measures of disruption, such as changes in the number of trips in and out of individual locales, are used to identify regions where users may be at particularly high risk of disruption. Using this complex network model, computationally efficient analysis strategies, and refined measures of disruption, we obtain new insights about users’ risk, and obtain results in formats that are usable by urban planners responsible for long-term management of the transportation system’s risk.

description: Most of the existing seismic resistant design codes are based on the response spectrum theory. The influence of inelastic deformations can be evaluated by considering inelastic type of resisting force and then the inelastic spectrum is considerably different from the elastic one. Also, the influence of stiffness degradation and strength deterioration can be accounted for by including more precise models from material point of view. In some recent papers the corresponding changes in response spectra due to the P- Ä effect are discussed. The experience accumulated from the recent earthquakes indicates that structural pounding may considerably influence the response of structures and should be taken into account in design procedures. The most convenient way to do that is to predict the influence of the pounding on the response spectra for accelerations, velocities and displacements. Generally speaking the contact problems such as pounding are characterized by large extent of nonlinearity and slow convergence of the computational procedures. Thus obtaining spectra where the contact problem is accounted for seems very attractive from engineering point of view because could easy be implemented into the design procedures. However it is worth nothing that there is not rigorous mathematical proof that the original system can be decomposed into single equations related to single degree of freedom systems. It is the porpose of the paper to study the influence of the pounding on the response spectra and to evaluate the amplification due to the impact. For this purpose two adjacent SDOF systems are considered that are able to interact during the vibration process. This problem is solved versus the elastic stiffness ratio, which appears to be very important for such assemblage. The contact between masses is numerically simulated using opening gap elements as links. Comparisons between calculated response spectra and linear response spectra are made in order to derive analytical relationships to simply obtain the contribution of pounding. The results are graphically illustrated in response spectra format and the influence of the stiffness ratio is clarified.

description: Network resilience to a disruption is generally considered to be a function of the initial impact of the disruption (the network’s vulnerability) and the trajectory of recovery after the disruption (the network’s recoverability). In the context of network resilience, this work develops and compares several flow-based importance measures to prioritize network edges for the implementation of preparedness options. For a particular preparedness option and particular geographically located disruption, we compare the different importance measures in their resulting network vulnerability, as well as network resilience for a general recovery strategy. Results suggest that a weighted flow capacity rate, which accounts for both (i) the contribution of an edge to maximum network flow and (ii) the extent to which the edge is a bottleneck in the network, shows most promise across four instances of varying network sizes and densities.

description: We start by providing an explicit characterization and analytical properties, including the persistence phenomena, of the distribution of the extinction time $\mathbb{T}$ of a class of non-Markovian self-similar stochastic processes with two-sided jumps that we introduce as a stochastic time-change of Markovian self-similar processes. For a suitably chosen time-changed, we observe, for classes with two-sided jumps, the following surprising facts. On the one hand, all the $\mathbb{T}$'s within a class have the same law which we identify in a simple form for all classes and reduces, in the spectrally positive case, to the Fréchet distribution. On the other hand, each of its distribution corresponds to the law of an extinction time of a single Markov process without positive jumps, leaving the interpretation that the time-changed has annihilated the effect of positive jumps. The example of the non-Markovian processes associated to Lévy stable processes is detailed.

description: Die digitale Unterstützung der Planungsprozesse ist ein aktueller Forschungs- und Arbeitsschwerpunkt der Professur Informatik in der Architektur (InfAR) und der Juniorprofessur Architekturinformatik der Fakultät Architektur an der Bauhaus-Universität Weimar. Verankert in dem DFG Sonderforschungsbereich 524 >Werkzeuge und Konstruktionen für die Revitalisierung von Bauwerken< entstehen Konzepte und Prototypen für eine fachlich orientierte Planungsunterstützung. In dem Beitrag wird ein Konzept und prototypische Realisierung für die durchgängige Unterstützung des gesamten Bauaufnahmeprozesses für Altbausubstanz vorgestellt und diskutiert. Der Fokus liegt auf der frühe Phase in der Bauaufnahme als ein Baustein in einer gesamtheitlichen IT-gestützen Planungsumgebung eingegangen. Durch gezielte Aufnahme planungsrelevanter Parameter und Auswertung hinsichtlich Wirtschaftlichkeit und Wiederverwendbarkeit bzw. der Variantenüberprüfung von Nutungskonzepten, werden gerade in dieser Phase wesentliche Entscheidungen für eine kostengünstige Planung getroffen werden. In der Veröffentlichung wird der Fokus auf folgende Punkte gesetzt: - Strukturierung und Aufnahme der Informationen während der Erstbegehung - Skizzenhafte Abbildung als Basis für die Formulierung erster Entwurfsintensionen/ Variantenuntersuchungen - Navigations- und Informationsumgebung - gezielte Auswertungsmöglichkeiten (bspw. Wirtschaftlichkeitsberechnung, Wiederverwendung von Bauteilen, Kalkulation von Abrissmengen)

description: Decision-making problems can be modeled as combinatorial optimization problems with Constraint Programming formalisms such as Constrained Optimization Problems. However, few Constraint Programming formalisms can deal with both optimization and uncertainty at the same time, and none of them are convenient to model problems we tackle in this paper. Here, we propose a way to deal with combinatorial optimization problems under uncertainty within the classical Constrained Optimization Problems formalism by injecting the Rank Dependent Utility from decision theory. We also propose a proof of concept of our method to show it is implementable and can solve concrete decision-making problems using a regular constraint solver, and propose a bot that won the partially observable track of the 2018 μRTS AI competition. Our result shows it is possible to handle uncertainty with regular Constraint Programming solvers, without having to define a new formalism neither to develop dedicated solvers. This brings new perspective to tackle uncertainty in Constraint Programming.

description:
Background: The 2020 Major League Baseball Season (MLB) demonstrated season disruptions due to the COVID-19 pandemic. Changes in training and seasonal time frames may be associated with higher rates of injury. Purpose: To use publicly available data to compare injury rates during the 2015-2019 seasons, COVID-19 shortened season (2020), and the 2021 season stratified by body region and position (pitchers versus position players). Study Design: A retrospective cohort study utilizing publicly available data. Methods: MLB players who competed in 1+ seasons between 2015-2021 were included and stratified by position (pitcher, position player). Incidence rate (IR), reported by 1000 x Athlete-Game Exposures (AGEs), was calculated for each season, and stratified by position and body region. Poisson regressions were performed for all injuries and stratified by position to determine association between season and injury incidence. Subgroup analyses were performed on the elbow, groin/hip/thigh, shoulder. Results: Four thousand, two hundred and seventy-four injuries and 796,502 AGEs across 15,152 players were documented. Overall IR was similar across seasons (2015-2019:5.39; 2020:5.85; 2021:5.04 per 1000 AGEs). IR remained high for the groin/hip/thigh for position players (2015-2019:1.7; 2020:2.0; 2021:1.7 per 1000 AGEs). There was no difference in injury rates between 2015-2019 and 2020 seasons [1.1 (0.9-1.2), p=0.310]. The 2020 season demonstrated a significant increase in elbow injuries [2.7 (1.8-4.0), p<0.001]; when stratified by position, this increase remained significant for pitchers [pitchers: 3.5 (2.1-5.9), p<0.001; position players: 1.8 (0.9-3.6), p=0.073]. No other differences were observed. Conclusion: The groin/hip/thigh demonstrated the highest IR in 2020 among position players across all season time frames, indicating that continued injury mitigation for this region is necessary. When stratified by body region, elbow injury rates among pitchers demonstrated 3.5 times the rate of injury in 2020 compared to previous seasons, impacting injury burden for the most vulnerable body region among pitchers. Level of Evidence: Level III.

description: In this paper we consider modelling of composite material with inclusions where the elastic material properties of both matrix and inclusions are uncertain and vary within prescribed bounds. Such mechanical systems, involving interval uncertainties and modelled by finite element method, can be described by parameter dependent systems of linear interval equations and process variables depending on the system solution. A newly developed hybrid interval approach for solving parametric interval linear systems is applied to the considered model and the results are compared to other interval methods. The hybrid approach provides very sharp bounds for the process variables - element strains and stresses. The sources for overestimation when dealing with interval computations are demonstrated. Based on the element strains and stresses, we introduce a definition for the values of nodal strains and stresses by using a set-theoretic approach.

description: Die physikalisch nichtlineare Analyse von Stahlbetontragwerken unter Berücksichtigung des Einspielverhaltens (adaptives Tragverhalten) mit Methoden der mathematischen Optimierung ist seit Jahren Gegenstand intensiver Forschungsarbeiten am Lehrstuhl Massivbau I der Bauhaus-Universität Weimar. Die dabei entwickelten Modelle und Algorithmen werden im folgenden Beitrag exemplarisch auf die Untersuchung von Aussteifungssystemen in Großtafelbauweise angewendet. Da bei diesen Gebäuden die aussteifende Konstruktion aus zusammengesetzten großformatigen Betonfertigteilen besteht, wird das Gesamttragverhalten maßgebend durch das Fugentragverhalten bestimmt. Die physikalische Nichtlinearität wird durch das Aufreißen der unbewehrten Horizontalfugen und den verschieblichen Verbund in den Vertikalfugen charakterisiert und entsprechend im Berechnungsmodell berücksichtigt. Beispielrechnungen belegen, dass für die beschriebenen Aussteifungssysteme signifikante Spannungsumlagerungen infolge des nichtlinearen Fugentragverhaltens auftreten. Weiterhin können Lastfolgeeffekte rechnerisch nachgewiesen werden. Im Gegensatz zu seismisch beanspruchten Systemen, die in kürzester Zeit wiederholt extrem beansprucht werden, ist die Eintrittswahrscheinlichkeit bemessungsrelevanter Windlasten gering.
