Adaptive surrogate model with active refinement combining kriging and a trust region method
Creators: name: Gaspar, B.
name: Teixeira, A. P.
name: Soares, C. Guedes
Publisher: name: The University of British Columbia
Year: 2015

description: In the present paper an adaptive Kriging surrogate model with active refinement is proposed to solve component reliability analysis problems (i.e. with a single design point) with a reasonable limit for the dimensionality of the basic random variables space. The model uses an adaptive Kriging-based trust region method to search for the design point and predict the failure probability based on the first-order reliability method. This prediction is then verified or improved using Monte Carlo simulation with importance sampling based on a Kriging surrogate model built up iteratively around the design point using an active refinement algorithm. The usefulness of the proposed surrogate model in terms of accuracy and efficiency for practical engineering applications is shown with a numerical example involving an advanced nonlinear FEA structural model.

description: The paper is devoted to a study of properties of homogeneous solutions of massless field equation in higher dimensions. We first treat the case of dimension 4. Here we use the two-component spinor language (developed for purposes of general relativity). We describe how are massless field operators related to a higher spin analogues of the de Rham sequence - the so called Bernstein-Gel'fand-Gel'fand (BGG) complexes - and how are they related to the twisted Dirac operators. Then we study similar question in higher (even) dimensions. Here we have to use more tools from representation theory of the orthogonal group. We recall the definition of massless field equations in higher dimensions and relations to higher dimensional conformal BGG complexes. Then we discuss properties of homogeneous solutions of massless field equation. Using some recent techniques for decomposition of tensor products of irreducible $Spin(m)$-modules, we are able to add some new results on a structure of the spaces of homogenous solutions of massless field equations. In particular, we show that the kernel of the massless field equation in a given homogeneity contains at least on specific irreducible submodule.

description: Information technology plays a key role in the everyday operation of buildings and campuses. Many proprietary technologies and methodologies can assist in effective Building Performance Monitoring (BPM) and efficient managing of building resources. The integration of related tools like energy simulator packages, facility, energy and building management systems, and enterprise resource planning systems is of benefit to BPM. However, the complexity to integrating such domain specific systems prevents their common usage. Service Oriented Architecture (SOA) has been deployed successfully in many large multinational companies to create integrated and flexible software systems, but so far this methodology has not been applied broadly to the field of BPM. This paper envisions that SOA provides an effective integration framework for BPM. Service oriented architecture for the ITOBO framework for sustainable and optimised building operation is proposed and an implementation for a building performance monitoring system is introduced.

description: Building information modeling offers a huge potential for increasing the productivity and quality of construction planning processes. Despite its promising concept, this approach has not found widespread use. One of the reasons is the insufficient coupling of the structural models with the general building model. Instead, structural engineers usually set up a structural model that is independent from the building model and consists of mechanical models of reduced dimension. An automatic model generation, which would be valuable in case of model revisions is therefore not possible. This can be overcome by a volumetric formulation of the problem. A recent approach employed the p-version of the finite element method to this problem. This method, in conjunction with a volumetric formulation is suited to simulate the structural behaviour of both „thick“ solid bodies and thin-walled structures. However, there remains a notable discretization error in the numerical models. This paper therefore proposes a new approach for overcoming this situation. It sugggests the combination of the Isogeometric analysis together with the volumetric models in order to integrate the structural design into the digital, building model-centered planning process and reduce the discretization error. The concept of the isogeometric analysis consists, roughly, in the application of NURBS functions to represent the geometry and the shape functions of the elements. These functions possess some beneficial properties regarding numerical simulation. Their use, however, leads to some intricacies related to the setup of the stiffness matrix. This paper describes some of these properties.

description: This paper deals with the modelling and the analysis of masonry vaults. Numerical FEM analyses are performed using LUSAS code. Two vault typologies are analysed (barrel and cross-ribbed vaults) parametrically varying geometrical proportions and constraints. The proposed model and the developed numerical procedure are implemented in a computer analysis. Numerical applications are developed to assess the model effectiveness and the efficiency of the numerical procedure. The main object of the present paper is the development of a computational procedure which allows to define 3D structural behaviour of masonry vaults. For each investigated example, the homogenized limit analysis approach has been employed to predict ultimate load and failure mechanisms. Finally, both a mesh dependence study and a sensitivity analysis are reported. Sensitivity analysis is conducted varying in a wide range mortar tensile strength and mortar friction angle with the aim of investigating the influence of the mechanical properties of joints on collapse load and failure mechanisms. The proposed computer model is validated by a comparison with experimental results available in the literature.

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

description: This paper introduces a multiple structural damage detection algorithm for structural health monitoring. We propose a sequential damage detection algorithm that uses the Bayesian inferences to diagnose multiple damages and their relationships. The proposed algorithm is purely data driven and does not require the prior knowledge of the structural properties. The sequential detectors are implemented by a computationally efficient message passing protocol that enables distributed and simultaneous damage detection. Also, the detectors achieve minimum detection delay with a desired false alarm rate. The performances of our algorithm are validated on the ASCE benchmark structure.

description: Since the 90-ties the Pascal matrix, its generalizations and applications have been in the focus of a great amount of publications. As it is well known, the Pascal matrix, the symmetric Pascal matrix and other special matrices of Pascal type play an important role in many scientific areas, among them Numerical Analysis, Combinatorics, Number Theory, Probability, Image processing, Sinal processing, Electrical engineering, etc. We present a unified approach to matrix representations of special polynomials in several hypercomplex variables (new Bernoulli, Euler etc. polynomials), extending results of H. Malonek, G.Tomaz: Bernoulli polynomials and Pascal matrices in the context of Clifford Analysis, Discrete Appl. Math. 157(4)(2009) 838-847. The hypercomplex version of a new Pascal matrix with block structure, which resembles the ordinary one for polynomials of one variable will be discussed in detail.

description: In this paper, a parameter identification procedure using Bayesian neural networks is proposed. Based on a training set of numerical simulations, where the material parameters are simulated in a predefined range using Latin Hypercube sampling, a Bayesian neural network, which has been extended to describe the noise of multiple outputs using a full covariance matrix, is trained to approximate the inverse relation from the experiment (displacements, forces etc.) to the material parameters. The method offers not only the possibility to determine the parameters itself, but also the accuracy of the estimate and the correlation between these parameters. As a result, a set of experiments can be designed to calibrate a numerical model.

description: A practical framework for generating cross correlated fields with a specified marginal distribution function, an autocorrelation function and cross correlation coefficients is presented in the paper. The contribution promotes a recent journal paper [1]. The approach relies on well known series expansion methods for simulation of a Gaussian random field. The proposed method requires all cross correlated fields over the domain to share an identical autocorrelation function and the cross correlation structure between each pair of simulated fields to be simply defined by a cross correlation coefficient. Such relations result in specific properties of eigenvectors of covariance matrices of discretized field over the domain. These properties are used to decompose the eigenproblem which must normally be solved in computing the series expansion into two smaller eigenproblems. Such decomposition represents a significant reduction of computational effort. Non-Gaussian components of a multivariate random field are proposed to be simulated via memoryless transformation of underlying Gaussian random fields for which the Nataf model is employed to modify the correlation structure. In this method, the autocorrelation structure of each field is fulfilled exactly while the cross correlation is only approximated. The associated errors can be computed before performing simulations and it is shown that the errors happen especially in the cross correlation between distant points and that they are negligibly small in practical situations.

description: Steel structural design is an integral part of the building construction process. So far, various methods of design have been applied in practice to satisfy the design requirements. This paper attempts to acquire the Differential Evolution Algorithms in automatization of specific synthesis and rationalization of design process. The capacity of the Differential Evolution Algorithms to deal with continuous and/or discrete optimization of steel structures is also demonstrated. The goal of this study is to propose an optimal design of steel frame structures using built-up I-sections and/or a combination of standard hot-rolled profiles. All optimized steel frame structures in this paper generated optimization solutions better than the original solution designed by the manufacturer. Taking the criteria regarding the quality and efficiency of the practical design into consideration, the produced optimal design with the Differential Evolution Algorithms can completely replace conventional design because of its excellent performance.

description: We consider a structural truss problem where all of the physical model parameters are uncertain: not just the material values and applied loads, but also the positions of the nodes are assumed to be inexact but bounded and are represented by intervals. Such uncertainty may typically arise from imprecision during the process of manufacturing or construction, or round-off errors. In this case the application of the finite element method results in a system of linear equations with numerous interval parameters which cannot be solved conventionally. Applying a suitable variable substitution, an iteration method for the solution of a parametric system of linear equations is firstly employed to obtain initial bounds on the node displacements. Thereafter, an interval tightening (pruning) technique is applied, firstly on the element forces and secondly on the node displacements, in order to obtain tight guaranteed enclosures for the interval solutions for the forces and displacements.

description: Nodal integration of finite elements has been investigated recently. Compared with full integration it shows better convergence when applied to incompressible media, allows easier remeshing and highly reduces the number of material evaluation points thus improving efficiency. Furthermore, understanding it may help to create new integration schemes in meshless methods as well. The new integration technique requires a nodally averaged deformation gradient. For the tetrahedral element it is possible to formulate a nodal strain which passes the patch test. On the downside, it introduces non-physical low energy modes. Most of these "spurious modes" are local deformation maps of neighbouring elements. Present stabilization schemes rely on adding a stabilizing potential to the strain energy. The stabilization is discussed within this article. Its drawbacks are easily identified within numerical experiments: Nonlinear material laws are not well represented. Plastic strains may often be underestimated. Geometrically nonlinear stabilization greatly reduces computational efficiency. The article reinterpretes nodal integration in terms of imposing a nonconforming C0-continuous strain field on the structure. By doing so, the origins of the spurious modes are discussed and two methods are presented that solve this problem. First, a geometric constraint is formulated and solved using a mixed formulation of Hu-Washizu type. This assumption leads to a consistent representation of the strain energy while eliminating spurious modes. The solution is exact, but only of theoretical interest since it produces global support. Second, an integration scheme is presented that approximates the stabilization criterion. The latter leads to a highly efficient scheme. It can even be extended to other finite element types such as hexahedrals. Numerical efficiency, convergence behaviour and stability of the new method is validated using linear tetrahedral and hexahedral elements.

description: The application of partly decoupled approach by means of continuum mechanics facilitates the calculation of structural responses due to welding. The numerical results demonstrate the ability of a qualitative prediction of welded connections. As it is intended to integrate the local effects of a joint in structural analysis of steel constructions, it is necessary to meet higher approaches towards quality. The wide array of material parameters are presented, which are affecting the thermal, metallurgical and mechanical behavior, and which have to be identified. For that purpose further investigations are necessary to analyze the sensitivity of the models towards different material properties. The experimental determination of every material parameter is not possible due to the extraordinary laborious efforts needed. Besides that, experimentally identified parameters can be applied only for the tested steel quality for measured temperature-time regimes. For that reason alternative approaches for identification of material parameters, such as optimization strategies, have to be applied. After a definition of material parameters a quantitative prediction of welded connections will also be possible. Numerical results show the effect of phase transformation, activated by welding process, on residual stress state. As these phenomena occur in local areas in the range of crystal and grain sizes, the description of microscopic phenomena and their propagation on a macroscopic level due to approaches of homogenization might be expedient. Nevertheless, one should bear in mind, the increasing number of material parameters as well as the complexity of their experimental determination. Thus the microscopic approach should always be investigated under the scope of ability and efficiency of a required prediction. Under certain circumstances a step backwards, adopting a phenomenological approach, also can be beneficial.

Compressive polynomial chaos expansion for multidimensional model maps
Creators: name: Marelli, Stefano
name: Sudret, Bruno
Publisher: name: The University of British Columbia
Year: 2015

description: Modern high-resolution numerical models used in engineering often produce multidimensional maps of outputs (e.g. nodal displacements on a FEM mesh) that may result in more than 105 highly correlated outputs for each set of model parameters. Most available metamodelling techniques, however, are not yet suitable for handling such large maps, including Polynomial Chaos Expansions (PCE). Indeed, the PCE of a numerical model with many outputs is traditionally handled by independently metamodelling each one of them. We introduce a two-stage PCE approach that aims at solving this problem: in the first stage, PCE is used to compress the map of outputs on a much sparser basis in the map coordinates; in the second stage, standard PCE of the compressed map is carried out w.r.t. the underlying model parameters. Standard PCE post-processing techniques are then used to derive analytical expressions for several stochastic properties of the resulting compressive PCE.

We describe the underlying abstract iteration scheme of the preconditioned perturbed iteration. We apply the iteration to a simple model problem in order to identify the main ideas which a numerical realization of the abstract scheme is based upon. This indicates how these concepts carry over to wavelet discretizations. Finally we present numerical results for the Poisson eigenvalue problem on an L-shaped domain.

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

description: This paper is in the context of risk-informed decision support and modeling infrastructure networks as socio-technical systems. The previously introduced Complex Distributed Agent Network Framework (CoDAN) framework is reviewed and several sources of uncertainty identified, along with possible paths to overcome it in future research. One key problem is addressed, regarding the selection of a decision horizon when engaging in resource allocation for disaster preparedness and its impact on the ratio of installation costs and displacement costs. Three optimization formulations are presented and compared for the resource allocation problem, considering several decision horizons. Results prove the computational efficiency of the proposed formulations and the effect of different decision horizons, which lead to diverse allocation schemes.

description: The blue light from the digital screens endangers the visual system among which the corneas at the outmost of eyes are vulnerable to the irradiation. Therein, the human corneal endothelial (HCE) cells are crucial to maintain corneal transparency and their damage leads to HCE decompensation resulting in blindness ultimately. Thus, understanding the phototoxic effects of the blue light on the HCE cells and the underlying mechanisms is important for taking measures to protect the vision clarity from the blue-light hazard. We pulse-irradiated the HCE cell line cells at logarithmic phase for 3 passages using 440 nm blue light and examined the levels of reactive oxygen species (ROS), ATP, nicotinamide adenine dinucleotide (NAD+) and autophagy using cytochemistry assay to investigate the alterations of energy metabolism. Moreover, we examined the γH2AX+ cells using immunofluorescence and expression of poly(ADP-Ribose)polymerase1 (PARP1) using western blotting to investigate the degrees of DNA damage and repair. We also monitored the levels of inflammasome using western blotting and senescence associated secretory phenotypes (SASPs) of interleukin (IL)-8, IL-1β and IL-6 using qPCR and ELISA to investigate the inflammasome assembly and secretion of SASPs. We detected the senescent features with senescence-associated-β-galactosidase assay, p16 levels by western blotting, Lamin B1 localization by immunofluorescence observation, cell growth by EdU incorporation assay and confluence forming time and alterations of the cell morphology and relative areas by microscopy observation. The HCE cells exhibited senescent features after blue-light-pulse-irradiation. The blue light provokes overproduction of ROS to decrease the levels of ATP, NAD+ and autophagy leading to energy crisis. Moreover, the excess ROS injure DNA and downregulate PARP1 resulting in stable cell-cycle arrest. The excess ROS also facilitate inflammasome assembly leading to hypersecretion of SASPs. The blue light elicits HCE cell senescence via inducing energy crisis, stable cell-cycle arrest and SASP hypersecretion.

Addressing uncertainty in ensemble sea-level rise predictions
Creators: name: Thomas, Matthew A.
name: Lin, Ting
Publisher: name: The University of British Columbia
Year: 2015

description: Sea-level rise represents a looming hazard to coastal communities which remains difficult to quantify. Ensemble climate change predictions incorporate epistemic uncertainty in the climate modeling process and climate forcing scenarios help portray a range of radiative forcing changes. This study proposes a method for incorporating both model and scenario uncertainty in ensemble projections of thermosteric sea-level rise. A Markov Chain Monte Carlo algorithm is utilized to weigh the contributions of eight process-based climate models as well as the four Representative Concentration Pathways based on convergence criteria and observational data. Hazard analysis and deaggregation combine these contributions over a range of sea-level rise thresholds and quantify the relative contributions of each pathway and prediction model. The hazard maps generated suggest improved accuracy in modeling regional trends over typical ensembles. Deaggregations effectively represent model and scenario differences and the impacts of the methods used.

description: Task 6.3 ‘Technical evolution of the PRACE operational services’ in work package 6 ‘Operation of the Distributed Research Infrastructure’ of PRACE-3IP continues the work from PRACE-1IP (WP6, Task 6.3). It also takes over the technical evolution of the PRACE operational services from work package 10 ‘Advancing the Operational Infrastructure’ in PRACE-2IP after the completion of WP10.
 In the first year 6.3 started to evaluate the Bolt software as a job submission tool complementing UNICORE.
 Also the evaluation of gsatellite has been started to provide additional functionality to GridFTP, the standard file transfer technology in PRACE.
 For PRACE internal needs the task members worked on and finished the setup of an internal GridFTP repository. Also the evaluation of DMOS is almost finished. Additionally the perfSONAR evaluation has been started.
 A further objective was the handover from WP10. This has been planned and agreed in detail with the WP10 members.

Strategies for separation of aleatory and epistemic uncertainties

description: Practical applications for separation of aleatory and epistemic uncertainties are demonstrated with two examples applied to steel structures and pipelines. These examples show the need for separation of uncertainties, the application of existing strategies and their limitations. The first example pertains to the behaviour of a simple steel connection subjected to combined axial, shear and moment loading. Uncertainties in the material properties of the connection components are shown to have a significant influence on the model uncertainty corresponding to the connection moment capacity. The second example shows that the uncertainties in the geometric imperfections of a steel pipeline contribute to the total model uncertainty in the strain capacity of the pipe. More such case studies demonstrating the utility of separation of epistemic uncertainty are expected to lead to increased efficiency in future model development.

description: This report describes the activities of Task 6.2 (WP6): Integration and upgrade of new Tier-0 and Tier-1 systems.
 A comprehensive procedure for monitoring and reporting the upgrade of a system in PRACE has been designed and tested. This procedure for the upgrade of a system must guarantee as much as possible an undisturbed migration of the PRACE services, with minimal impact on the services at other sites. It has been designed to be applied both for Tier-0 and Tier-1 systems. The procedure has been successfully applied for the upgrade of three systems: MareNostrum at BSC from Tier-1 to Tier-0, which is reported in this document, and Cartesius at SURFsara and SiSu at CSC. The upgrades of the latter two are both for Tier-1 systems and are managed by PRACE-2IP as part of the operations of the Tier-1 infrastructure. The experience of these upgrades is used for improving the procedure itself. The upgrade procedure, as discussed in this document, consists of nine steps that should cover all possible scenarios.
 Two new Tier-0 systems have successfully been taken in service in this project period, an IBM BlueGene/Q system at CINECA, Italy, and an IBM iDataPlex DX360M4 system at BSC, Spain. Both these systems replaced an existing Tier-1 system.
 This task also started the integration of two new Tier-1 sites, NIIF in Hungary and CaSToRC on Cyprus. The procedure being used to integrate these systems is the same used by other Tier-1 systems in PRACE-2IP.
A random field representation based on stochastic harmonic functions

description: Random field models are widely adopted in engineering practice, for instance, to describe the mechanical properties of an engineering site or a civil structure. The most widely employed approach to represent a random field is the spectral representation. In the present paper, a new stochastic harmonic function representation by partitioning the wave number domain is proposed. The properties of the new representation are studied. A numerical example is studied to illustrate the proposed method.
Compression and inference algorithms for Bayesian network modeling of infrastructure systems

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

description: The Bayesian network (BN) is an ideal tool for modeling and assessing the reliability of civil infrastructure, particularly when the information about the system and its components is uncertain and evolves in time. One of the major limitations of the BN framework, however, is the size and complexity of the system that can be tractably modeled as a BN. This is due to the size of the conditional probability table (CPT) associated with the system node in the BN model, which grows exponentially with the number of components in the system. In this paper, we present novel compression and inference algorithms that utilize compression techniques to achieve significant savings in memory storage of the system CPT. In addition, heuristics developed to improve the computational efficiency of the algorithms are presented. An application to an example system demonstrates the gains in both memory and computation time requirements achieved by the proposed algorithms.

description: Der Anteil der Menschen, die übergewichtig bis fettleibig sind, ist heute ebenso groß wie der Anteil derjenigen, die an Hunger leiden – jeweils fast eine Milliarde! Die Beiträge hinterfragen, welche Handlungsalternativen wir im Hinblick auf unsere individuelle und globale Ernährungssituation haben. Sie zeigen auf, was wir tun können, um den globalen Hunger zu bekämpfen, und was wir tun müssen, um die individuelle Ernährungssituation in den Griff zu bekommen. Zurzeit sehen wir mit der Umnutzung von Ackerböden für den Non-Food-Bereich Entwicklungen, die die globale Nahrungsmittelverfügbarkeit weiter verschärfen. Dazu werden Fragen der Nahrungsmittelproduktion und Verteilung – bis hin zum Einsatz von Gentechnik – behandelt, um eine ausreichende Versorgung der Weltbevölkerung zu erreichen. Der Band diskutiert Ursachen und Folgen von Über- und Mangelernährung und hebt besonders die gesundheitspolitische Relevanz der Ernährungsfrage hervor.

description: The objective of this report is to present the work that has been done in year one by work package 6, task 6.1, of the PRACE-3IP project on the Operations of the PRACE distributed infrastructure for Tier-0 systems. This work is the continuation of the work done by task 6.1 and 6.2 of the PRACE-1IP project.
 A new version of the PRACE Service Catalogue, which describes the PRACE common services, has been prepared. The update procedure has been added and two new services have been added as a result of successful evaluations. The new version has been submitted for acceptance by the Tier-0 partners.
 In the process towards PRACE Quality of Service and quality control the work on PRACE Operational Key Performance Indicators has been continued. For most of the proposed Indicators the implementation of measurements has been completed and an evaluation will be started in year two.
 The Security Forum, responsible for all security related activities, is coordinated by this task. A new version of the Acceptable Use Policy (AUP) for Tier-0 users has been prepared and is submitted to Tier-0 partners for acceptance. Risk reviews of the services Grid-SAFE, gtransfer, gsatellite and UNICORE FTP, have been completed as part of the evaluation of new services.
 Based on the procedures for incident and change management the complete set of PRACE common services as defined in the Service Catalogue have been implemented and operated: Network (e.g. the dedicated PRACE network), Data services (e.g., GridFTP), Compute services (e.g., UNICORE), AAA services (e.g., user administration, PRACE Accounting services, GSI-SSH), Monitoring services (e.g., Inca), and User services (e.g., PRACE Common Production Environment, PRACE Help Desk).
 Six Tier-0 systems are operational at the end of this project period: JUQUEEN at GCS@FZJ; CURIE at GENCI@CEA; HERMIT at GCS@HLRS; SuperMUC at GCS@LRZ; FERMI at CINECA; MareNostrum at BSC The systems at CINECA and BSC have been successfully added to the PRACE infrastructure this year and the system JUGENE at GCS@FZJ has been replaced by the JUQUEEN system.
