description: Bridge vibration due to traffic loading has been subject of extensive research in the last decades. Such studies are concerned with deriving solutions for the bridge-vehicle interaction (BVI) and analyzing the dynamic responses considering randomness of the coupled model’s (BVI) input parameters and randomness of road unevenness. This study goes further to examine the effects of such randomness of input parameters and processes on the variance of dynamic responses in quantitative measures. The input parameters examined in the sensitivity analysis are, stiffness and damping of vehicle’s suspension system, axle spacing, and stiffness and damping of bridge. This study also examines the effects of the initial excitation of a vehicle on the influences of the considered input parameters. Variance based sensitivity analysis is often applied to deterministic models. However, the models for the dynamic problem is a stochastic one due to the simulations of the random processes. Thus, a setting using a joint meta-model; one for the mean response and other for the dispersion of the response is developed. The joint model is developed within the framework of Generalized Linear Models (GLM). An enhancement of the GLM procedure is suggested and tested; this enhancement incorporates Moving Least Squares (MLS) approximation algorithms in the fitting of the mean component of the joint model. The sensitivity analysis is then performed on the joint-model developed for the dynamic responses caused by BVI.

description: A numerical simulation scheme is presented that combines the advantages of the spectral representation method (SRM) and the idea of random function to generate fully non-stationary ground motion. In the paper, firstly, a new family of spectral representation method is proposed. Secondly, these standard orthogonal random variables in SRM formula can be defined as the orthogonal function form of a basic random variable, and the original stochastic process can be represented as a function of the basic random variable. Its advantage is proved that fully non-stationary ground motion can be completely represented by a dimension-reduced spectral model with just few elementary random variables through defining the high-dimensional standard orthogonal random variables of classical spectral representation into the low-dimensional orthogonal random function. Finally, it provides an opportunity to incorporate the probability density evolution method (PDEM), and study the stochastic dynamics in engineering.

description: Bibliotherapy, the therapeutic use of books to promote mental health, has long been recognized as an effective intervention (Shechtman, 2009). With the rapid advancement of digital technology, a new modality, known as 'digital bibliotherapy', has emerged. Digital bibliotherapy utilizes digital books, literature, and other reading materials delivered through electronic devices such as computers, tablets, and smartphones, to offer therapeutic benefits (Bergsland & Strøm, 2020). This modern approach integrates the traditional principles of bibliotherapy with the convenience and accessibility of digital platforms, potentially enhancing its reach and impact. Digital bibliotherapy offers several advantages, including increased accessibility to diverse literature and the ability to tailor interventions to individual needs. This abstract explores the evolution of bibliotherapy into the digital age, examining its applications, benefits, and potential challenges. By leveraging the growing accessibility of digital technology, digital bibliotherapy presents a promising avenue for addressing mental health concerns and promoting resilience among individuals facing various psychological challenges
In Space There Is No Status Quo: Space Communities as Social Experimentation Regarding Reproduction and Kinship
Creators: name: Kendal, Evie
Publisher: name: Swinburne
Year: 2024

description: Human societies possess various moral and legal codes that rely on precedent; an act can be considered “right” simply by virtue of its having always been done that way before. Cultural norms can be hard to challenge, and laws are often slow to change. Emerging technologies are often cast as a threat to social values, with reproductive technologies representing a particular concern if they challenge traditionally held views of kinship and family structure. Creating a multicultural community of humans in space provides an opportunity to explore alternative reproductive futures and family arrangements without exposing existing human societies to unknown risks or being constrained by precedent. As social norms for such a community have not yet been established, conscious and deliberate consideration of how we might want such a community to form and propagate is possible. As family-making is an essential element of society building, this chapter will consider emerging reproductive technologies in the light of future space exploration and habitation.

description: The process of analysis and design in structural engineering requires the consideration of different partial models, for example loading, structural materials, structural elements, and analysis types. The various partial models are combined by coupling several of their components. Due to the large number of available partial models describing similar phenomena, many different model combinations are possible to simulate the same aspects of a structure. The challenging task of an engineer is to select a model combination that ensures a sufficient, reliable prognosis. In order to achieve this reliable prognosis of the overall structural behavior, a high individual quality of the partial models and an adequate coupling of the partial models is required. Several methodologies have been proposed to evaluate the quality of partial models for their intended application, but a detailed study of the coupling quality is still lacking. This paper proposes a new approach to assess the coupling quality of partial models in a quantitative manner. The approach is based on the consistency of the coupled data and applies for uni- and bidirectional coupled partial models. Furthermore, the influence of the coupling quality on the output quantities of the partial models is considered. The functionality of the algorithm and the effect of the coupling quality are demonstrated using an example of coupled partial models in structural engineering.

description: Maintenance and management policies are usually focused on minimizing the life-cycle cost only. Therefore the optimal solution in this context does not necessarily result in a satisfactory long-term structural performance. In this paper, we will present an approach for modeling the degradation of structures and infrastructures for maintenance purposes. The degradation is modeled using probabilistic data-driven state dependent stochastic processes, hereafter called meta-model. This work implements this degradation model into a maintenance framework and carries out two numerical examples in order to show the applicability of our meta-model in a maintenance and management optimization context. This paves the road for future work on meta-model updating and maintenance optimization by considering a multi-objective optimization policies.

description: The pavement is one of the basic components of road infrastructure and, therefore, directly influences general levels of transport safety, as well as the quality of transportation services in human and cargo traffic. It also exerts a major influence on the final logistic costs of production and services in many aspects of everyday life. The continuity of transportation, which is closely tied to the development of a number of areas in the economy of every State, depends on the technical condition of the road pavement. Making proper investments in the complete course of life of the road pavement, a policy which makes sure that the conditions for continuous, safe, efficient, and economically optimised transportation are satisfied, is a priority for every administration managing municipal funds. If investments in the road pavement are not carried out properly, there usually are more and more road pavements the condition of which causes delays in transportation, and directly compromises traffic safety. Such a situation increases the running costs of vehicles, and decreases the transportation service levels and comfort of travelling. At the moment, the majority of pavements in Europe, (nearly 90% of all pavements) are flexible road pavements. Due to the prevalent number of flexible pavements in Europe, the author analyses investment in the course of full-time of life cycle of the pavements, with a stress on flexible pavements. The paper presents basic assumptions and definitions in the area of analysis of life cycle costs of a flexible road pavement, as well as profits associated with proper long range investment. The classification of damages to flexible road pavement has also been presented, and their influence on technical and use related assessment of road pavement conditions, basing on the traditional road pavement structures, with relation to the catalogue of typical flexible pavements used in Poland, as well as regarding French, British, and American experience in constructing long life road pavements. The second part of the paper discusses different investment strategies in the course of a full-time of life cycle of the road pavement, and proposes a procedure of evaluating investment strategies. The summary presents some assumptions for a global index of investment evaluation during the full-time of life cycle of a pavement, based on the Best Return Index (BRI).

description: Areas with various defects and damages, which reduce carrying capacity, were examined in a study of metal chimneys. In this work, the influence of the local dimples on the function of metal chimneys was considered. Modeling tasks were completed in the software packages LIRA and ANSYS. Parameters were identified, which characterize the local dimples, and a numerical study of the influence of local dimples on the stress-strain state of shells of metal chimneys was conducted. A distribution field of circular and meridional tension was analyzed in a researched area. Zones of influence of dimples on the bearing cover of metal chimneys were investigated. The bearing capacities of high-rise structures with various dimple geometries and various cover parameters were determined with respect to specified areas of the trunk. Dependent relationships are represented graphically for the decrease in bearing capacity of a cover with respect to dimples. Diameter and thickness of covers of metal chimneys were constructed according to the resulting data.

description: The natural material wood is commonly graded with regard to the parallel to the grain strength and stiffness properties and taking into account different growth characteristics such as knots and grain deviations. In this paper the impact of knots and grain deviations on the fracture perpendicular to the grain of timber is analysed by means of numerical models. The results are used for the calibration of an analytical model. With this model it is possible to evaluate the impact of growth characteristics on the perpendicular to the grain fracture and compare the results with test data from literature. The evaluation shows that certain growth characteristics increase the strength perpendicular to the grain. This is in contrast with current grading procedures, where such growth characteristics are considered as being strength decreasing. The results are compared with a model for the description of the effects of growth characteristics on the distribution characteristics of the strength perpendicular to the grain. This strongest link model can be used to describe phenomena with a parallel system of failure events.
Entangled Fields in Motion: A Unified Approach to  Understanding Causality, Disturbance, and Emergence

description: This paper introduces a new framework for understanding causality, disturbance, and emergence in quantum systems. It proposes that the future state of quantum systems may influence their past, challenging traditional views of time and causality. The concept of entangled fields in motion is presented, where quantum systems evolve as interconnected fields across both space and time.

The paper also suggests a new experiment to test this model, exploring how future events could affect a photon’s wave-particle behavior. This work could lead to a paradigm shift in quantum theory, offering new insights into time, causality, and field dynamics, while laying the groundwork for future experimental exploration.

description: Many structures in different engineering applications suffer from cracking. In order to make reliable prognosis about the serviceability of those structures it is of utmost importance to identify cracks as precisely as possible by non-destructive testing. A novel approach (XIGA), which combines the Isogeometric Analysis (IGA) and the Extended Finite Element Method (XFEM) is used for the forward problem, namely the analysis of a cracked material, see [1]. Applying the NURBS (Non-Uniform Rational B-Spline) based approach from IGA together with the XFEM allows to describe effectively arbitrarily shaped cracks and avoids the necessity of remeshing during the crack identification problem. We want to exploit these advantages for the inverse problem of detecting existing cracks by non-destructive testing, see e.g. [2]. The quality of the reconstructed cracks however depends on two major issues, namely the quality of the measured data (measurement error) and the discretization of the crack model. The first one will be taken into account by applying regularizing methods with a posteriori stopping criteria. The second one is critical in the sense that too few degrees of freedom, i.e. the number of control points of the NURBS, do not allow for a precise description of the crack. An increased number of control points, however, increases the number of unknowns in the inverse analysis and intensifies the ill-posedness. The trade-off between accuracy and stability is aimed to be found by applying an inverse multilevel algorithm [3, 4] where the identification is started with short knot vectors which successively will be enlarged during the identification process.

description: Magneto-rheological (MR) damper has proved its value in vibration mitigation of engineering structures subjected to dynamic excitations such as seismic ground motion and strong wind. The accurate operation, however, of MR damper still remains a challenge due to incomplete knowledge on the randomness inherent in the dynamical behaviors of the damper. While the classical models of MR damper are most of phenomenal formulation lacking of the in-depth analysis of working mechanism at material scale. The stochastic modeling of MR damper is carried out in this paper of which the variability definition of critical parameters renders to the dynamic yield analysis of Magneto-rheological fluids. A randomly base-excited structure controlled by the MR damper is investigated. Numerical results indicate that the MR damping control can reduce the seismic response significantly, where the distribution range of probability density function becomes narrower comparing with that without control. It is thus remarked that the appropriately designed semi-active controller can achieve almost the same effect as the active controller in probabilistic sense. The randomness, meanwhile, of damper parameters could be neglected safely.

Following the ideas given for real quaternion analysis, the paper deals with certain orthogonal decompositions of the complex quaternion Hilbert space into its subspaces of null solutions of Dirac type operator with an arbitrary complex potential. We then apply them to consider related boundary value problems, and to prove the existence and uniqueness as well as the explicit representation formulae of the underlying solutions.

The results of this activity are expected to be that students can use their cellphones or gadgets for learning purposes at school, not just for fun and playing games. Because at SMP Negeri 1 Aek, Batu City, many students already have cellphones, which means these cellphones will have a big influence on minors. This cellphone could be a threat to students who are important as the nation's next generation because technological developments in children can create very bad character. Children become addicted to playing on cellphones without time limits. Even though underage children still need education, which is very important for survival. A child's good and bad character can change over time, especially bad character will emerge due to the negative influence of technological developments that are misused by certain individuals. Even parents of a child easily give their child a cell phone to make their child quiet even though this can have an impact. hurry for the child.

description: Sensitivity analysis of fluid-structure interaction (FSI) simulations provides an important tool for assessing the reliability and performance of coastal infrastructure subjected to storm and tsunami hazards. As a preliminary step for gradient-based applications in reliability, optimization,system identification, and performance-based engineering of coastal infrastructure, the direct differentiation method (DDM) is applied to FSI simulations using the particle finite element method (PFEM) to compute sensitivities of simulated FSI response with respect to uncertain parameters of the structural and fluid domains that are solved in a monolithic system via the PFEM. Due to geometric nonlinearity of the free-surface flow, geometric sensitivity of the fluid is considered in the governing equations of the DDM along with sensitivity of material nonlinear response in the structural domain. An example application shows sensitivity to load and resistance variables of a reinforced concrete frame subjected to tsunami loading with open and closed first story design configurations.

description: This paper presents a robust model updating strategy for system identification of wind turbines. To control the updating parameters and to avoid ill-conditioning, the global sensitivity analysis using the elementary effects method is conducted. The formulation of the objective function is based on M¨uller-Slany’s strategy for multi-criteria functions. As a simulationbased optimization, a simulation adapter is developed to interface the simulation software ANSYS and the locally developed optimization software MOPACK. Model updating is firstly tested on the beam model of the rotor blade. The defect between the numerical model and the reference has been markedly reduced by the process of model updating. The effect of model updating becomes more pronounced in the comparison of the measured and the numerical properties of the wind turbine model. The deviations of the frequencies of the updated model are rather small. The complete comparison including the free vibration modes by the modal assurance criteria shows the excellent coincidence of the modal parameters of the updated model with the ones from the measurements. By successful implementation of the model validation via model updating, the applicability and effectiveness of the solution concept has been demonstrated.

description: This report presents the work performed by work package 6 of the PRACE-3IP project on the operation of the PRACE distributed infrastructure for Tier-0 and Tier-1 systems for the work extension in period July 2014 to end of January 2015.
 The main activity for this period has been the operation and coordination of the PRACE common services, which enable the interoperation among different PRACE HPC systems and which present a common interface to the PRACE Tier-0 and PRACE Tier-1 systems.
 Because of the limited available effort in this period for operational activities the number of new proposed changes has been limited to the inevitable ones, such as the removal of a system or a configuration change at a site.
 On operational security of the infrastructure, information on major vulnerabilities in basic system software has been exchanged and one incident at a partner site has been reported.
 Six Tier-0 systems have been operational for the project period under review: JUQUEEN at GCS@FZJ; CURIE at GENCI@CEA; SuperMUC at GCS@LRZ; Hermit at GCS@HLRS, upgraded to Hornet FERMI at CINECA; MareNostrum at BSC Hermit at GCS@HLRS, has been upgraded to a new system, Hornet, also at GCS@HLRS. With a peak performance of 3.8 PFlop/s for the new system this brings the total Tier-0 peak performance above 18 PFlop/s.
 Three Tier-1 systems have been upgraded in capacity, one has been replaced and one site has disappeared from the list. 23 Tier-1 sites are operational at the end of January 2015.
 Support for the enhancement of interoperability between PRACE and XSEDE has been given to three collaborating teams with members from both Europe and the US.

description: The aim of our contribution is to clarify the relation between totally regular variables and Appell sequences of hypercomplex holomorphic polynomials (sometimes simply called monogenic power-like functions) in Hypercomplex Function Theory. After their introduction in 2006 by two of the authors of this note on the occasion of the 17th IKM, the latter have been subject of investigations by different authors with different methods and in various contexts. The former concept, introduced by R. Delanghe in 1970 and later also studied by K. Gürlebeck in 1982 for the case of quaternions, has some obvious relationship with the latter, since it describes a set of linear hypercomplex holomorphic functions all power of which are also hypercomplex holomorphic. Due to the non-commutative nature of the underlying Clifford algebra, being totally regular variables or Appell sequences are not trivial properties as it is for the integer powers of the complex variable z=x+ iy. Simple examples show also, that not every totally regular variable and its powers form an Appell sequence and vice versa. Under some very natural normalization condition the set of all para-vector valued totally regular variables which are also Appell sequences will completely be characterized. In some sense the result can also be considered as an answer to a remark of K. Habetha in chapter 16: Function theory in algebras of the collection Complex analysis. Methods, trends, and applications, Akademie-Verlag Berlin, (Eds. E. Lanckau and W. Tutschke) 225-237 (1983) on the use of exact copies of several complex variables for the power series representation of any hypercomplex holomorphic function.

description: A set of publications were selected to examine the specification of the word “spoiling” (or “spoiled”). The was selection that was primarily drawn from references used in my PhD thesis and underlying publications. A further selection criterion was the presence of the string “spoil” (as in spoiling, spoiled, spoiler) in the context of gradient-echo sequences. Hits in references were not considered. This delivered over 80 hits. By a random selection, the set was further limited to 50 hits.It was sorted on whether the term “spoiling”/”spoiled”/”spoiler” was accompanied by the specification “RF-“, “coherent gradient”, or that it was just tagged with “gradient”, or not specified at all.

This document reports the outcome of these statistics.

description: Civil engineers take advantage of models to design reliable structures. In order to fulfill the design goal with a certain amount of confidence, the utilized models should be able to predict the probable structural behavior under the expected loading schemes. Therefore, a major challenge is to find models which provide less uncertain and more robust responses. The problem gets even twofold when the model to be studied is a global model comprised of different interacting partial models. This study aims at model quality evaluation of global models with a focus on frame-wall systems as the case study. The paper, presents the results of the first step taken toward accomplishing this goal. To start the model quality evaluation of the global frame-wall system, the main element (i.e. the wall) was studied through nonlinear static and dynamic analysis using two different modeling approaches. The two selected models included the fiber section model and the Multiple-Vertical-Line-Element-Model (MVLEM). The influence of the wall aspect ratio (H=L) and the axial load on the response of the models was studied. The results from nonlinear static and dynamic analysis of both models are presented and compared. The models resulted in quite different responses in the range of low aspect ratio walls under large axial loads due to different contribution of the shear deformations to the top displacement. In the studied cases, the results implied that careful attention should be paid to the model quality evaluation of the wall models specifically when they are supposed to be coupled to other partial models such as a moment frame or a soil-footing substructure which their response is sensitive to shear deformations. In this case, even a high quality wall model would not result in a high quality coupled system since it fails to interact properly with the rest of the system.

description: Due to the complex interactions between the ground, the driving machine, the lining tube and the built environment, the accurate assignment of in-situ system parameters for numerical simulation in mechanized tunneling is always subject to tremendous difficulties. However, the more accurate these parameters are, the more applicable the responses gained from computations will be. In particular, if the entire length of the tunnel lining is examined, then, the appropriate selection of various kinds of ground parameters is accountable for the success of a tunnel project and, more importantly, will prevent potential casualties. In this context, methods of system identification for the adaptation of numerical simulation of ground models are presented. Hereby, both deterministic and probabilistic approaches are considered for typical scenarios representing notable variations or changes in the ground model.

description: Background/Question/Methods

Urban landscapes are increasingly required to act as sites of conservation, raising questions regarding how to manage cities to concurrently conserve species and support human well-being. We seek to identify similarities and differences in the habitat preferences of urban humans and birds, thus identifying urban landscape attributes that could be managed to support both species conservation and human well-being.  We focus our analysis on Iowa City, Iowa, USA, a small city in an agricultural landscape that typifies urban development in the US Corn Belt. To assess human habitat preferences, we develop a hedonic pricing model using spatial regression techniques to identify the contribution of different environmental features (tree cover; species richness; greenspace; impervious surface; areas, connectivity, and fragmentation of natural land covers) to home sale prices.  We use resulting economic values for attributes to indicate habitat preferences of urban homeowners.  We then construct habitat occupancy models for a set of urban bird species using field-collected data to identify relationships with environmental attributes similar to those used in hedonic pricing models.  We use the resulting models to indicate bird habitat preferences. We compare the identified preferences to assess similarities and differences in the habitat preferences of urban humans and birds.

Results/Conclusions

We find that some aspects of the urban environment (tree canopy, areas of several natural land covers) are positively-valued by humans and positively-related to the occurrence of some species.  Other characteristics (impervious surfaces) exhibit negative relationships to both property values and species occurrence.  These results suggest that human and bird habitat preferences can overlap and that natural land covers and vegetation could be managed to support both bird conservation and human well-being.  However, we find great variation among bird species and notable differences in landscape structure preferences among humans and birds.  Thus, the habitat preferences of many bird species differ from human preferences.  Managing urban landscapes to simultaneously support a broad array of species and human quality-of-life is thus likely to be challenging.

description: Topology optimization as a form-finding methodology for design has developed rapidly in recent years. Its applications can vary from small-scale material microstructures to large-scale building systems. While deterministic optimization of structural systems under static loading is well understood, optimization under dynamic loading is less studied, and the more challenging problem of finding optimal structural systems under stochastic dynamic loading has not yet been addressed. In this work, topology optimization is used to design the lateral load system of structures such that the expected system responses to stationary stochastic excitations are optimized. More specifically, we design the size and location of bracings for multi-story building to minimize the variance of relative deformations under stationary base excitations. To evaluate the variance, we first solve this problem in frequency domain by using the autospectral density function of the relative displacement for the covariant stationary situation. This is compared to analysis in time domain through use of the impulse response function. The resulting stochastic dynamic topology optimization problem is solved using the gradient-based optimizer Method of Moving Asymptotes (MMA), with sensitivities provided via the adjoint method. The popular Solid Isotropic Material with Penalization (SIMP) is used to prevent existence of low-area bracing members and provide clear indications of bracing patterns. Numerical results are presented and comparisons of time and frequency domain methods are given.
