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

description: From passenger’s perspective, punctuality is one of the most important features of tram route operation. We present a stochastic simulation model with special focus on determining important factors of influence. The statistical analysis bases on large samples (sample size is nearly 2000) accumulated from comprehensive measurements on eight tram routes in Cracow. For the simulation, we are not only interested in average values but also in stochastic characteristics like the variance and other properties of the distribution. A realization of trams operations is assumed to be a sequence of running times between successive stops and times spent by tram at the stops divided in passengers alighting and boarding times and times waiting for possibility of departure . The running time depends on the kind of track separation including the priorities in traffic lights, the length of the section and the number of intersections. For every type of section, a linear mixed regression model describes the average running time and its variance as functions of the length of the section and the number of intersections. The regression coefficients are estimated by the iterative re-weighted least square method. Alighting and boarding time mainly depends on type of vehicle, number of passengers alighting and boarding and occupancy of vehicle. For the distribution of the time waiting for possibility of departure suitable distributions like Gamma distribution and Lognormal distribution are fitted.

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

description: We demonstrate a method for incorporating wind measurements from multiple-point scanning lidars into the turbulence fields serving as input to wind turbine load simulations. The measurement values are included in the analysis by applying constraints to randomly generated turbulence fields. A numerical study shows the application of the constrained turbulence method to load simulations on a 10MW wind turbine model, using two example lidar patterns – a 5-point pattern forming a square with a central point, and a circular one. Based on the results of this study, we assess the influence of applying the proposed method on the statistical uncertainty in wind turbine extreme and fatigue loads.

description: Models in the context of engineering can be classified in process based and data based models. Whereas the process based model describes the problem by an explicit formulation, the data based model is often used, where no such mapping can be found due to the high complexity of the problem. Artificial Neuronal Networks (ANN) is a data based model, which is able to “learn“ a mapping from a set of training patterns. This paper deals with the application of ANN in time dependent bathymetric models. A bathymetric model is a geometric representation of the sea bed. Typically, a bathymetry is been measured and afterwards described by a finite set of measured data. Measuring at different time steps leads to a time dependent bathymetric model. To obtain a continuous surface, the measured data has to be interpolated by some interpolation method. Unlike the explicitly given interpolation methods, the presented time dependent bathymetric model using an ANN trains the approximated surface in space and time in an implicit way. The ANN is trained by topographic measured data, which consists of the location (x,y) and time t. In other words the ANN is trained to reproduce the mapping h = f(x,y,t) and afterwards it is able to approximate the topographic height for a given location and date. In a further step, this model is extended to take meteorological parameters into account. This leads to a model of more predictive character.

description: In this paper the influence of changes in the mean wind velocity, the wind profile power-law coefficient, the drag coefficient of the terrain and the structural stiffness are investigated on different complex structural models. This paper gives a short introduction to wind profile models and to the approach by Davenport A. G. to compute the structural reaction of wind induced vibrations. Firstly with help of a simple example (a skyscraper) this approach is shown. Using this simple example gives the reader the possibility to study the variance differences when changing one of the above mentioned parameters on this very easy example and see the influence of different complex structural models on the result. Furthermore an approach for estimation of the needed discretization level is given. With the help of this knowledge the structural model design methodology can be base on deeper understanding of the different behavior of the single models.

description: Euclidean Clifford analysis is a higher dimensional function theory offering a refinement of classical harmonic analysis. The theory is centered around the concept of monogenic functions, i.e. null solutions of a first order vector valued rotation invariant differential operator called the Dirac operator, which factorizes the Laplacian. More recently, Hermitean Clifford analysis has emerged as a new and successful branch of Clifford analysis, offering yet a refinement of the Euclidean case; it focusses on the simultaneous null solutions, called Hermitean (or h-) monogenic functions, of two Hermitean Dirac operators which are invariant under the action of the unitary group. In Euclidean Clifford analysis, the Clifford-Cauchy integral formula has proven to be a corner stone of the function theory, as is the case for the traditional Cauchy formula for holomorphic functions in the complex plane. Previously, a Hermitean Clifford-Cauchy integral formula has been established by means of a matrix approach. This formula reduces to the traditional Martinelli-Bochner formula for holomorphic functions of several complex variables when taking functions with values in an appropriate part of complex spinor space. This means that the theory of Hermitean monogenic functions should encompass also other results of several variable complex analysis as special cases. At present we will elaborate further on the obtained results and refine them, considering fundamental solutions, Borel-Pompeiu representations and the Teoderescu inversion, each of them being developed at different levels, including the global level, handling vector variables, vector differential operators and the Clifford geometric product as well as the blade level were variables and differential operators act by means of the dot and wedge products. A rich world of results reveals itself, indeed including well-known formulae from the theory of several complex variables.

description: In the context of finite element model updating using vibration test data, natural frequencies and mode shapes are used as validation criteria. Consequently, the order of natural frequencies and mode shapes is important. As only limited spatial information is available and noise is present in the measurements, the automatic selection of the most likely numerical mode shape corresponding to a measured mode shape is a difficult task. The most common criterion to indicate corresponding mode shapes is the modal assurance criterion. Unfortunately, this criterion fails in certain cases. In this paper, the pure mathematical modal assurance criterion will be enhanced by additional physical information of the numerical model in terms of modal strain energies. A numerical example and a benchmark study with real measured data are presented to show the advantages of the enhanced energy based criterion in comparison to the traditional modal assurance criterion.

description: This paper presents a probabilistic framework for vulnerability analysis of electric transmission towers subjected to unbalanced ice loads using the concepts of statistical learning theory (SLT). Based on SLT, the implicit limit state function of each element is replaced by an approximate polynomial function that has good prediction properties. The results are presented in the form of fragility curves for 3 different unbalanced loading scenarios of longitudinal, transverse and torsional loadings. Such fragility information provides us with a better understanding of the behavior of various components of the line under different climatic conditions. It can also be used to evaluate existing transmission towers and to optimize the design of new ones. This paper further studies the effect of various design parameters such as wind speed and direction, icing rate and location of ice formation on the fragility curves of tension and suspension towers. The results show higher failure probabilities for suspension towers than tension towers. The results also indicate that for most conditions, longitudinal loads are more important than other unbalanced loading scenarios. Finally, this study concludes that wind speed, wind direction and ice accumulation rate have notable effects on the fragility curves.

description: The consideration of snow load is important for regions experiencing severe winter climate and snowfall, such as Heilongjiang Province located in northeastern China. In this study, annual maximum snow depth from 1981 to 2010 for 83 stations in Heilongjiang was used as the basis to carry out extreme value analysis and to estimate ground snow load. To reduce the sample size effect in the extreme value analysis, the region of influence (ROI) approach is considered and the results are compared with those obtained from at-site analysis as well as from the current Chinese load code. Maps are developed for the region based on the estimated return period value of the ground snow load.

description: For better or for worse, we are in the habit of holding new cultural artefacts to pretty high standards when it comes to their socio-political messaging. A memorable recent example is Barbie, the Greta Gerwig/Margot Robbie film about the eponymous toy that sought to do the impossible: rehabilitate Barbie as a feminist. This was always going to be a tall order given that, as Andi Zeisler wrote in The New York Times last year, “Barbie holds the weight of several generations’ worth of beauty standards and feminist analysis on her tiny shoulders.” But perhaps we shouldn’t look for social analysis or a radical emancipatory feminist project in something that is too wrapped up in the various systems it seeks to criticise. This article considers whether truly radical art must exist “outside” the systems in wants to criticise, or whether it is possible for artworks to critique from within.

description: The application of a recent method using formal power series is proposed. It is based on a new representation for solutions of Sturm-Liouville equations. This method is used to calculate the transmittance and reflectance coefficients of finite inhomogeneous layers with high accuracy and efficiency. Tailoring the refraction index profile defining the inhomogeneous media it is possible to develop very important applications such as optical filters. A number of profiles were evaluated and then some of them selected in order to perform an improvement of their characteristics via the modification of their profiles.

We also tackle the question of how to display African objects repaired with a Western element that were forgotten in storage, and how to have an emotional relation to artefacts in the museum, a fundamentally sacralized institution.

description: The presented material model reproduces the anisotropic characteristics of textile reinforced concrete in a smeared manner. This includes both the initial anisotropy introduced by the textile reinforcement, as well as the anisotropic damage evolution reflecting fine patterns of crack bridges. The model is based on the microplane approach. The direction-dependent representation of the material structure into oriented microplanes provides a flexible way to introduce the initial anisotropy. The microplanes oriented in a yarn direction are associated with modified damage laws that reflect the tension-stiffening effect due to the multiple cracking of the matrix along the yarn.

Infludence of failure modes of RC columns on simplified seismic loss assessment
Creators: name: De Luca, Flavia
name: Galasso, Carmine
Publisher: name: The University of British Columbia
Year: 2015

description: A simplified loss assessment is carried out considering regionally-based design practice for reinforced concrete (RC) buildings. In particular, a 4-story RC moment resisting frame (MRF) is designed according to obsolete seismic Italian design provisions, resulting in a structure characterized by typical features of the building stock in the area struck by the 2009 L’Aquila earthquake. For the same design, two different executive hypotheses are considered, resulting in two non-ductile RC structural configurations dominated by two different failure modes of primary elements, i.e., flexure-shear- and shear- dominated. The loss assessment includes a site-specific hazard analysis, a pushover-based approach for seismic demand assessment, and a simplified damage and cost analyses focused on the RC columns. It is employed to evaluate the risk of earthquake economic losses, and the influence of structural design decisions on these losses.

description: In this paper we devise a new multi-dimensional integral transform within the Clifford analysis setting, the so-called Fourier-Bessel transform. It appears that in the two-dimensional case, it coincides with the Clifford-Fourier and cylindrical Fourier transforms introduced earlier. We show that this new integral transform satisfies operational formulae which are similar to those of the classical tensorial Fourier transform. Moreover the L2-basis elements consisting of generalized Clifford-Hermite functions appear to be eigenfunctions of the Fourier-Bessel transform.

description: This paper describes the application of interval calculus to calculation of plate deflection, taking in account inevitable and acceptable tolerance of input data (input parameters). The simply supported reinforced concrete plate was taken as an example. The plate was loaded by uniformly distributed loads. Several parameters that influence the plate deflection are given as certain closed intervals. Accordingly, the results are obtained as intervals so it was possible to follow the direct influence of a change of one or more input parameters on output (in our example, deflection) values by using one model and one computing procedure. The described procedure could be applied to any FEM calculation in order to keep calculation tolerances, ISO-tolerances, and production tolerances in close limits (admissible limits). The Wolfram Mathematica has been used as tool for interval calculation.

description: In the present article we will construct wavelets on an arbitrary dimensional sphere S^n due the approach of approximate Identities. There are two equivalently approaches to wavelets. The group theoretical approach formulates a square integrability condition for a group acting via unitary, irreducible representation on the sphere. The connection to the group theoretical approach will be sketched. The concept of approximate identities uses the same constructions in the background, here we select an appropriate section of dilations and translations in the group acting on the sphere in two steps. At First we will formulate dilations in terms of approximate identities and than we call in translations on the sphere as rotations. This leads to the construction of an orthogonal polynomial system in L²(SO(n+1)). That approach is convenient to construct concrete wavelets, since the appropriate kernels can be constructed form the heat kernel leading to the approximate Identity of Gauss-Weierstra\ss. We will work out conditions to functions forming a family of wavelets, subsequently we formulate how we can construct zonal wavelets from a approximate Identity and the relation to admissibility of nonzonal wavelets. Eventually we will give an example of a nonzonal Wavelet on $S^n$, which we obtain from the approximate identity of Gauss-Weierstraß.

description: In nonlinear simulations the loading is, in general, applied in an incremental way. Path-following algorithms are used to trace the equilibrium path during the failure process. Standard displacement controlled solution strategies fail if snap-back phenomena occur. In this contribution, a path-following algorithm based on the dissipation of the inelastic energy is presented which allows for the simulation of snap-backs. Since the constraint is defined in terms of the internal energy, the algorithm is not restricted to continuum damage models. Furthermore, no a priori knowledge about the final damage distribution is required. The performance of the proposed algorithm is illustrated using nonlinear mesoscale simulations.

description: This present paper deals with the choice of stochastic expansion models for load processes in structural reliability of floating wind turbines. Two widely used models, the spectral representation method and the Karhunen-Loeve (KL) expansion are compared as far as their use in reliability assessment based on real world wind speed data. The use of expansion models makes it possible to compute the outcrossing rate using time invariant reliability methods. We assume stationary conditions and define and compare several outcrossing rate estimators based on a design point computation. We first adapt the PHI2 method to functionals, and specify a closed form of Koo et al. (2005)’s estimator for the KL model. An importance sampling scheme based on the design point with and without an additional Monte Carlo Markov Chain sampler is then suggested and its effectiveness is assessed for the KL model.

description: An ideal controller assumes that the system is unconstrained and the control force in unbounded. However, in reality, control devices are restricted by their force capacity. Traditionally, the clipping strategy has been used extensively, where an ideal actuator is assumed in the control design, and then the inequality constraints are enforced through saturation. This approach may not provide optimal solutions since constraints are not considered in the control optimization. To overcome this limitation, this paper presents a constrained nonlinear stochastic optimal control algorithm for dynamic systems subjected to Gaussian white noise excitations. In this control algorithm, stochasticity and nonlinearity of a Hamiltonian dynamic system is considered based on stochastic averaging of energy envelope using Markovian approximation. An Ito equation of energy envelope is derived and represented by diffusion and drift components. For the control design, a prescribed cost function, the diffusion and drift components together with the force constraints are considered in solving the Hamilton Jacobian Bellman (HJB) equation. This proposed control approach is called here Constrained Stochastic Control (CSC). The performance of the CSC algorithm is demonstrated for a hysteretic column and the results are compared to simulation results for Clipped Stochastic Control (Cl-SC) and uncontrolled cases. Noticeable improvements in peak and root mean square values of displacement in the CSC case are observed over the Cl-SC algorithm.

description: After mixing of concrete, the hardening starts by an exothermic chemical reaction known as hydration. As the reaction rate depends on the temperature the time in the description of the hydration is replaced by the maturity which is defined as an integral over a certain function depending on the temperature. The temperature distribution is governed by the heat equation with a right hand side depending on the maturity and the temperature itself. We compare of the performance of different time integration schemes of higher order with an automatic time step control. The simulation of the heat distribution is of importance as the development of mechanical properties is driven by the hydration. During this process it is possible that the tensile stresses exceed the tensile strength and cracks occur. The goal is to produce cheap concrete without cracks. Simple crack-criterions use only temperature differences, more involved ones are based on thermal stresses. If the criterion predicts cracks some changes in the input data are needed. This can be interpreted as optimization. The final goal will be to adopt model based optimization (in contrast to simulation based optimization) to the problem of the hydration of young concrete and the avoidance of cracks. The first step is the simulation of the hydration, which we focus in this paper.

description: This article explores the ritual system of Matsuzawa Yutaka’s early mandalas. Adapted from the nine-panel Diamond Realm mandala format of Esoteric Buddhism, Matsuzawa’s mandala system poses two opposite space-time paths: one radiating clockwise from the centre (from 1 to 9), and the other revolving anticlockwise to the centre (from 9 to 1). A third space-time experience from both the beginning and end could also be achieved by seeing 1 through 9 simultaneously. While Matsuzawa’s art draws from a wide range of historic thought including science, theology, and parapsychology, this article focuses on its connections to the traditions arising from the Lake Suwa area of Nagano, Japan. It begins with Matsuzawa’s gohei mandalas from the late 1950s in which he incorporated forms derived from Shinto ritual objects into the nine-panel mandala format. It then discusses the artist’s experimentations in the early 1960s that culminated in his three-dimensional mandalas known as the Psi Chamber and Psi Altar, stressing the importance of the accompanying writings and diagrams provided in his first text-based work, On “Meaning of Psi” and “Psi Chamber” from 1961. This article concludes by examining Matsuzawa’s 1973 account of his transcendental engagement, facilitated by his activated Psi Chamber mandala system, with the Shinto festival known as the Onbashira Matsuri associated with the Suwa Taisha near his home.

description: Mark Cousins is a Northern Irish director and writer. Well-known for ‘The Story of Film: An Odyssey’ (2011, headlined as the cinematic event of the year) and A New Generation (2021)’. Both comprehensive chronologies of world cinema are praised for their detailed and diverse approaches. His esteemed film-making career spans five decades. The following interview is presented as a discussion in response to the latter half of his film ‘The Story of Looking.’ The film meditates on the richness of visual experiences, framed around Cousins preparing for surgery to restore his vision during COVID. For the majority of the film Cousins narrates alone in the dark from his bed; as such, this interview was conducted via Zoom with us both in our respective beds. The hope was this exercise in free association and viewing would provide an emergent insight into Cousin’s film philosophy, hence our comfortable viewing locations to encourage us to pause the viewing and discuss thoughts freely as they came to mind. I collated the most striking thoughts relevant to the systems facilitating filmmaking; the still and timestamp from those moments are provided.
title: Developmental Course of Peer Problems and Co-occurring Behavioural Problems During Childhood and Adolescence (Age 5–17)

description: Purpose: Peer relationships are crucial to psychosocial development, and peer difficulties in childhood predict behavioural difficulties later in life. Yet, there is a lack of literature on the developmental trajectory of peer problems. I aim to identify common peer problem profiles and map their longitudinal transitions across childhood and adolescence. Method: Strengths and Difficulties Questionnaire data from the population-representative Millennial Cohort Study was analysed with factor analysis, followed by a data-driven clustering approach to extract subgroups of peer and co-occurring problems from ages 5 to 17. I then mapped the transitions between profiles and identified risk factors predicting significant transitions. Results: Peer problems often co-occurred with other behavioural problems. As children developed from 5 to 7, the peer problem clusters gradually became broader, encompassing emotional difficulties and hyperactivity. From 7 to 11 the profile became refined, returning to mainly peer problems; then from 11 to 14 the peer problem phenotype expanded again to include emotion and hyperactivity issues. Longitudinal and concurrent risk factors at ages 5, 7, and 11 were identified to predict these negative transitions. Conclusion: Peer problems show a non-linear trajectory of change when tracked longitudinally through childhood and adolescence. Whilst they generally increase with time, they are associated with different co-occurring difficulties and form complex profiles throughout development. These transitions are, to some extent, predictable on the basis of risk factors such as child longstanding illness, time spent on sports and exercise, and parental mental health.

description: Recently the research community has come to appreciate the severe impact that many factors have on the variability of RNA Sequencing (RNA-Seq) data. The fact that local variance introduces global variance is main problem with RNA-Seq pre-processing. For example one highly variable gene will introduce variance in all other expressed genes. Originally the primary factors of concern were the total read depth and the feature length and the FPKM normalization mitigate the variance of these two factors. However, many other factors that add to the global variance have been discovered. For example, the ribosomal content, the mitochondrial content, the variable fragment length distribution, variable 3' bias, variable exon/intron/intergenic balance, variable sense/anti-sense balance, etc. Which factors matter depends on whether one is doing gene level analysis, isoform level analysis, or exon/intron/junction level analysis. All currently available normalization methods use a scaling approach that takes place after quantification, but this does not solve most of the problems adequately. Instead we have implemented a normalization pipeline called PORT that uses resampling at the read-alignment level, producing normalized SAM files. PORT starts with fastq files and produces as output a set of SAM files that have the same number of reads in each, as well as the same number of exon-mapping reads in each, the same number of intron-mapping reads in each, etc. These files are then used to quantify features after which no further normalization is necessary. PORT is implemented in Perl and runs on a cluster and is highly configurable.
