Structural engineering

description: A novel hybrid simulation scheme combining the finite element (FE) method with artificial intelligence (AI) technique is proposed in this paper. This newly established AI-FE hybrid simulation is based on the existing hybrid simulation concept but introducing a well-trained AI model to replace the previous high-resolution substructure model of high computational demand. The AI-FE hybrid simulation framework is implemented taking advantage of the open-source platform OpenSees for fire with Python interpreter and the advanced machine learning algorithms derived from AI development. The first attempt of AI-FE hybrid simulation is applied for modelling a 2D steel plane frame with central heated column, which has been a reference test of many hybrid simulation research. To realize the real-time communication between the FE structural model and the AI sub-model, a new generic element dispBeamColumnThermalAI is developed. It is ported to an AI model trained using the SVM regression model from the samples generated from a detailed FE model subjected to various loading histories. A comparison between the computed results by the AI-FE model, the traditional FE model and the measured test results in terms of axial displacement and internal axial force demonstrates the robust capability of AI-FE hybrid simulation in capturing the structural response to fires, especially the global buckling of heated column.

description: Geometric structures on $\mathbb N Q$-manifolds, i.e.~non-negatively graded manifolds with an homological vector field, encode non-graded geometric data on Lie algebroids and their higher analogues. A particularly relevant class of structures consists of vector bundle valued differential forms. Symplectic forms, contact structures and, more generally, distributions are in this class. We describe vector bundle valued differential forms on non-negatively graded manifolds in terms of non-graded geometric data. Moreover, we use this description to present, in a unified way, novel proofs of known results, and new results about degree one $\mathbb N Q$-manifolds equipped with certain geometric structures, namely symplectic structures, contact structures, involutive distributions (already present in literature) and locally conformal symplectic structures, and generic vector bundle valued higher order forms, in particular presymplectic and multisymplectic structures (not yet present in literature).

description: We introduce an Eulerian approach for problems involving one or more soft solids immersed in a fluid, which permits mechanical interactions between all phases. The reference map variable is exploited to simulate finite-deformation constitutive relations in the solid(s) on the same fixed grid as the fluid phase, which greatly simplifies the coupling between phases. Our coupling procedure, a key contribution in the current work, is shown to be computationally faster and more stable than an earlier approach, and admits the ability to simulate both fluid--solid and solid--solid interaction between submerged bodies. The interface treatment is demonstrated with multiple examples involving a weakly compressible Navier--Stokes fluid interacting with a neo-Hookean solid, and we verify the method's convergence. The solid contact method, which exploits distance-measures already existing on the grid, is demonstrated with two examples. A new, general routine for cross-interface extrapolation is introduced and used as part of the new interfacial treatment.

description: We study cells in generalised Bott-Samelson varieties for type C. These cells are parametrised by certain galleries in the affine building. We define a set of readable galleries - we show that the closure in the affine Grassmannian associated to a gallery in this set is an MV cycle. This then defines a map from the set of readable galeries to the set of MV cycles, which we show to be a morphism of crystals. We further compute the fibres of this map in terms of the Littelmann path model.

description: The concept of negative temperature has recently received renewed interest in the context of debates about the correct definition of the thermodynamic entropy in statistical mechanics. Several researchers have identified the thermodynamic entropy exclusively with the "volume entropy'' suggested by Gibbs, and have further concluded that by this definition, negative temperatures violate the principles of thermodynamics. We disagree with these conclusions. We demonstrate that volume entropy is inconsistent with the postulates of thermodynamics for systems with non-monotonic energy densities, while a definition of entropy based on the probability distributions of macroscopic variables does satisfy the postulates of thermodynamics. Our results confirm that negative temperature is a valid extension of thermodynamics.

description: Abstract 
The avoidance of reading and studying books, magazines, newspapers, etc., but also society's transition to fast and short reading in those of social networks and communications have started partly for informative concepts, but also the ways of misuse or avoidance. Of the standard Albanian language.The use and misuse of language by social networks is seen at all levels of formal and informal communications. The use of unreasonable and meaningless words and sentences, but also phonetically, morphologically and syntactically incorrect, can be seen in a high degree of carelessness and linguistic abuse.This study will present some fragments and analyses, but also the linguistic role of words and sentences used in social networks by our educational institutions or by various public figures and up to those of new age communications.

description: In this paper, a new theoretical two-phase (solid–liquid) type model of melting temperature has developed based on the modified Gibbs–Thomson equation. Further, it is extended to derive other different size-dependent thermodynamic properties such as cohesive energy, Debye temperature, specific heat capacity, the thermal and electrical conductivity of metallic nanoparticles. Quantitative calculation of the effect of size on thermodynamic properties resulted in, varying linearly with the inverse of characteristic length of nanomaterials. The models are applied to Al, Pb, Ag, Sn, Mo, W, Co, Au and Cu nanoparticles of spherical shape. The melting temperature, Debye temperature, thermal and electrical conductivity are found to decrease with the decrease in particle size, whereas the cohesive energy and specific heat capacity are increased with the decrease in particle size. The present model is also compared with previous models and found consistent. The results obtained with this model validated with experimental and simulation results from several sources that show similar trends between the model and experimental results.

description: This paper starts with an exposition of descent-theoretic techniques in the study of Picard groups of $\mathbf{E}_{\infty}$-ring spectra, which naturally lead to the study of Picard spectra. We then develop tools for the efficient and explicit determination of differentials in the associated descent spectral sequences for the Picard spectra thus obtained. As a major application, we calculate the Picard groups of the periodic spectrum of topological modular forms $TMF$ and the non-periodic and non-connective $Tmf$. We find that $\mathrm{Pic} (TMF)$ is cyclic of order 576, generated by the suspension $ΣTMF $ (a result originally due to Hopkins), while $\mathrm{Pic}(Tmf) = \mathbb{Z}\oplus \mathbb{Z}/24$. In particular, we show that there exists an invertible $Tmf$-module which is not equivalent to a suspension of $Tmf$.

description: Countable projective limits of countable inductive limits, so-called PLB-spaces, of weighted Banach spaces of continuous functions have recently been investigated by Agethen, Bierstedt and Bonet, who analyzed locally convex properties in terms of the defining double sequence of weights. We complement their results by considering a defining sequence which is the product of two single sequences. By associating these two sequences with a weighted Fréchet, resp. LB-space of continuous functions or with two weighted Fréchet spaces (by taking the reciprocal of one of the sequences) we derive a representation of the PLB-space as the tensor product of a Fréchet and a DF-space and exhibit a connection between the invariants (DN) and ($Ω$) for Fréchet spaces and locally convex properties of the PLB-space resp. of the forementioned tensor product.

description: Excerpt from the report Introduction: One of the most widely used insecticides in the United States and in the world is DDT. It is effective against a large number of pests whose control is important to assure adequate supplies of food and fiber. Its broad spectrum insecticidal properties, combined with long residual life and relative safety in handling, make it desirable for many control purposes. DDT is a recommended control for at least 150 pests which can damage economic crops. DDT decomposes very slowly under certain conditions, is almost insoluble in water, and has a tendency to accumulate in the fatty tissue of warm-blooded animals including man. There is some concern that certain types of wildlife may be adversely affected by this tendency. This report shows recent use of DDT in U.S. farm production and indicates trends in total U.S. production of DDT and its overall use.

description: Observational data, especially astrophysical data, is often limited by gaps in data that arises due to lack of observations for a variety of reasons. Such inadvertent gaps are usually smoothed over using interpolation techniques. However the smoothing techniques can introduce artificial effects, especially when non-linear analysis is undertaken. We investigate how gaps can affect the computed values of correlation dimension of the system, without using any interpolation. For this we introduce gaps artificially in synthetic data derived from standard chaotic systems, like the R{ö}ssler and Lorenz, with frequency of occurrence and size of missing data drawn from two Gaussian distributions. Then we study the changes in correlation dimension with change in the distributions of position and size of gaps. We find that for a considerable range of mean gap frequency and size, the value of correlation dimension is not significantly affected, indicating that in such specific cases, the calculated values can still be reliable and acceptable. Thus our study introduces a method of checking the reliability of computed correlation dimension values by calculating the distribution of gaps with respect to its size and position. This is illustrated for the data from light curves of three variable stars, R Scuti, U Monocerotis and SU Tauri. We also demonstrate how a cubic spline interpolation can cause a time series of Gaussian noise with missing data to be misinterpreted as being chaotic in origin. This is demonstrated for the non chaotic light curve of variable star SS Cygni, which gives a saturated D$_{2}$ value, when interpolated using a cubic spline. In addition we also find that a careful choice of binning, in addition to reducing noise, can help in shifting the gap distribution to the reliable range for D$_2$ values.

description: Consider $n$ independent and identically distributed $p$-dimensional Gaussian random vectors with covariance matrix $Σ.$ The problem of estimating $Σ$ when $p$ is much larger than $n$ has received a lot of attention in recent years. Yet little is known about the information criterion for covariance matrix estimation. How to properly define such a criterion and what are the statistical properties? We attempt to answer these questions in the present paper by focusing on the estimation of bandable covariance matrices when $p>n$ but $\log(p)=o(n)$. Motivated by the deep connection between Stein's unbiased risk estimation (SURE) and AIC in regression models, we propose a family of generalized SURE ($\text{SURE}_c$) indexed by $c$ for covariance matrix estimation, where $c$ is some constant. When $c$ is 2, $\text{SURE}_2$ provides an unbiased estimator of the Frobenious risk of the covariance matrix estimator. Furthermore, we show that by minimizing $\text{SURE}_2$ over all possible banding covariance matrix estimators we attain the minimax optimal rate of convergence and the resulting estimator behaves like the covariance matrix estimator obtained by the so-called oracle tuning. On the other hand, we also show that $\text{SURE}_2$ is selection inconsistent when the true covariance matrix is exactly banded. To fix the selection inconsistency, we consider using SURE with $c=\log(n)$ and prove that by minimizing $\text{SURE}_{\log(n)}$ we select the true bandwith with probability tending to one. Therefore, our analysis indicates that $\text{SURE}_2$ and $\text{SURE}_{\log(n)}$ can be regarded as the AIC and BIC for large covariance matrix estimation, respectively.

description: This paper presents the synthesis of Barium Oxide Nanoparticles (BaO-NPs) on a large-scale by a simple and cost-effective co-precipitation method. The as-synthesized BaO-NPs were characterized in aspects of their structural, morphological, compositional, and optical properties. X-ray diffraction was done to assess the crystalline property of the nanomaterial and the crystallite size of the BaO-NPs was found to be 15–16 nm. Scanning electron microscopy was used to study the morphology of as-synthesized nanoparticles which confirmed that the prepared materials are flower-shaped nanoparticles. The compositional characteristics of nanoparticles were given by Fourier transform infrared spectroscopy which confirmed that the as-synthesized nanoparticles are pure BaO. A useful optical properties of nanoparticles were also reported via the room temperature UV–Vis and photoluminescence spectroscopy and calculated bandgap of the nanoparticles was found 4.65 eV.

description: Empirical likelihood approach is one of non-parametric statistical methods, which is applied to the hypothesis testing or construction of confidence regions for pivotal unknown quantities. This method has been applied to the case of independent identically distributed random variables and second order stationary processes. In recent years, we observe heavy-tailed data in many fields. To model such data suitably, we consider symmetric scalar and multivariate $α$-stable linear processes generated by infinite variance innovation sequence. We use a Whittle likelihood type estimating function in the empirical likelihood ratio function and derive the asymptotic distribution of the empirical likelihood ratio statistic for $α$-stable linear processes. With the empirical likelihood statistic approach, the theory of estimation and testing for second order stationary processes is nicely extended to heavy-tailed data analyses, not straightforward, and applicable to a lot of financial statistical analyses.

Wesentliches Ziel der Modellversuche war die Antwort auf die Fragestellung nach der formstabilen Herstellbarkeit von nicht ummantelten Sandsäulen in weichen organischen Böden sowie deren resultierendes Last-Verformungsverhalten. Gegenstand der Untersuchungen war, neben dem Einfluss des gewählten Säulenherstellungsverfahrens, der Einfluss des organischen Anteils des Bodens als auch des gewählten Flächenverhältnisses. Die Ergebnisse der Modellversuche wurden in einer Modellfamilie zusammengefasst und auf In-situ-Verhältnisse extrapoliert. Als Grundlage eines Bemessungskonzepts wurde das in der Praxis für Baugrundverbesserungen etablierte Verfahren nach Priebe gewählt, dessen Erweiterung auf der Grundlage der eigenen Untersuchungsergebnisse erfolgte. Die Plausibilität und Validität der vorgeschlagenen Erweiterung konnte mit den Setzungsmessungen eines großmaßstäblichen Modellversuchs als auch anhand eines Bauvorhabens aus dem Straßenbau nachgewiesen werden. Abschließend wird auf die noch offengebliebenen Fragen zu dieser Baugrundverbesserungsmethode eingegangen.

description: We use midinfrared pulses with stable carrier-envelope phase offset to drive molecular vibrations in the charge transfer salt ET-F2TCNQ, a prototypical one-dimensional Mott insulator. We find that the Mott gap, which is probed resonantly with 10 fs laser pulses, oscillates with the pump field. This observation reveals that molecular excitations can coherently perturb the electronic on-site interactions (Hubbard U) by changing the local orbital wave function. The gap oscillates at twice the frequency of the vibrational mode, indicating that the molecular distortions couple quadratically to the local charge density.

description: A major problem in road network analysis is discovery of important crossroads, which can provide useful information for transport planning. However, none of existing approaches addresses the problem of identifying network-wide important crossroads in real road network. In this paper, we propose a novel data-driven based approach named CRRank to rank important crossroads. Our key innovation is that we model the trip network reflecting real travel demands with a tripartite graph, instead of solely analysis on the topology of road network. To compute the importance scores of crossroads accurately, we propose a HITS-like ranking algorithm, in which a procedure of score propagation on our tripartite graph is performed. We conduct experiments on CRRank using a real-world dataset of taxi trajectories. Experiments verify the utility of CRRank.

description: We study the one-shot zero-error classical capacity of a quantum channel assisted by quantum no-signalling correlations, and the reverse problem of exact simulation of a prescribed channel by a noiseless classical one. Quantum no-signalling correlations are viewed as two-input and two-output completely positive and trace preserving maps with linear constraints enforcing that the device cannot signal. Both problems lead to simple semidefinite programmes (SDPs) that depend only on the Kraus operator space of the channel. In particular, we show that the zero-error classical simulation cost is precisely the conditional min-entropy of the Choi-Jamiolkowski matrix of the given channel. The zero-error classical capacity is given by a similar-looking but different SDP; the asymptotic zero-error classical capacity is the regularization of this SDP, and in general we do not know of any simple form. Interestingly however, for the class of classical-quantum channels, we show that the asymptotic capacity is given by a much simpler SDP, which coincides with a semidefinite generalization of the fractional packing number suggested earlier by Aram Harrow. This finally results in an operational interpretation of the celebrated Lovasz $\vartheta$ function of a graph as the zero-error classical capacity of the graph assisted by quantum no-signalling correlations, the first information theoretic interpretation of the Lovasz number.

description: This thesis analyzes some aspects of the relationship between health and economic growth from a theoretical point of view. It consists of two papers, one co-authored and one single-authored. The co-authored paper ?Children's health, human capital accumulation, and R&D-based economic growth? describes the role of children's health for human capital accumulation and for long-run economic growth. For this purpose we design an R&D-based growth model in which the stock of human capital of the next generation is determined by parental education and health investments. We show that i) there is a complementarity between education and health: if parents want to have better educated children, they also raise health investments and vice versa; ii) parental health investments exert an unambiguously positive effect on long-run economic growth, iii) faster population growth reduces long-run economic growth. These results are consistent with the empirical evidence for modern economies in the twentieth century. In the single-authored paper ?Different Types of Health Expenditures in an OLG framework: living longer or working better??, the health status of individuals affects their longevity and their labor productivity. We include public health expenditures into an overlapping-generations model. The government faces the trade-off investing its revenues either into the health expenditure that makes the labor force productive, or into the health expenditure that increases life expectancy. We show how the government optimally allocates the resources between the two types of health expenditures. The results are remarkable because by using a straightforward structure of the economy, we are able to combine two strings of the existing literature about the impacts of health: higher life expectancy and higher worker productivity.

description: In concern of Travelling Fire in a large compartment, normally two temperature fields are classified, which are a near field in the flame region with high temperature and a far field in the rest region with smoke temperature [1]. In 2011, Travelling Fire Methodology (TFM) [1] was proposed, which combines Alpert’s ceiling jet correlation, to account for the far field smoke temperature and a uniform temperature zone for the near field. Improved Travelling Fires Methodology (iTFM) [2] was then developed with the gas temperature analytical solution for far-field and flame flapping for near field. Travelling Fire Methodology with flame extension (fTFM) [3] was further developed using heat flux boundary conditions. An Extended Travelling Fire Methodology (ETFM) framework was conceptually proposed by Dai et al. [4] also using heat flux boundary conditions. All these Travelling Fire Methodologies use gas temperature or heat flux as boundary conditions to calculate the thermal response of the component; nevertheless, these methods are mainly applied in calculation software (i.e. MATLAB) or OpenSEES for the fire which is short of visualization of the thermal response of components. And some analysis types, element types, material models are not developed in OpenSEES. The use of Travelling Fire Methodology in finite element software is limited. In this paper, a numerical simulation method based on ANSYS or Abaqus is proposed for the thermal response of components under travelling fire, which can use either gas temperature or heat flux boundary conditions. The component is divided into different partitions, and then the gas temperature or heat flux history is calculated by user-defined functions and loaded to the corresponding partition, which simulates a component in a temporally and spatially non-uniform temperature distribution. The restart technique is adopted for heat flux boundary conditions. Parametric modelling methods are recommended for this method, and the method can be used for other travelling fire methodologies. The numerical simulation method based on ANSYS or Abaqus could make the best use of the existing finite element software (material model, element type, analysis types, and pre-and post-processing modules) to provide more accurate analysis results.

description: Mit dem Bundesgesetz über die Gleichstellung von Menschen mit Behinderungen und der Ratifizierung der UN-Konvention über die Rechte von Menschen mit Behinderungen verfolgt die Schweiz das internationale Ziel der schulischen Inklusion. Der Ressourceneinsatz für sonderpädagogische Angebote kann dazu beitragen. Doch über den Einsatz der Ressourcen, besonders für einfache sonderpädagogische Angebote, ist wenig bekannt. Die Bildungsstatistik des Bundes erfasst die Daten nur lückenhaft. Ziel dieser Arbeit ist es, durch den Einsatz des Fragebogens von Ladner (2021) zur Erhebung von Angebot und Nutzung einfacher sonderpädagogischer Angebote im Kanton Schwyz, diese Lücke zu füllen. Der Fragebogen wurde an alle Schwyzer Primarschulleitungen gesandt und von sieben Personen ausgefüllt. Die Auswertung der Daten verdeutlicht, wie schwierig es noch immer ist, nutzbare Daten hinsichtlich der einfachen sonderpädagogischen Angebote zu erheben. Bei künftigen Befragungen müssen gezielte Strategien zur Erhöhung der Rücklaufquote und Datenqualität berücksichtigt werden.

description: Soil health is vital for many ecosystem services and crucial for achieving the Sustainable Development Goals and the European Green Deal's goals. The Horizon Europe (HE) Mission “A Soil Deal for Europe” aims to accelerate the transition to sustainable soil and land management, and healthy soils through an ambitious transdisciplinary research and innovation (R&I) programme, largely based on actor engagement, Living Labs and Lighthouses. The H2020 Soil Mission Support (SMS) project supports the implementation of the HE Mission and aims to improve the coordination of R&I on sustainable soil and land management. Through a co-creation process together with actors, SMS collates available knowledge, actors R&I needs and identifies R&I gaps that need to be addressed for successful transition towards sustainable soil and land management.
 The presented R&I roadmap on soils and land management is a strategic document outlining the actions and the pathway to address R&I needs from different actors and sectors, as well as societal challenges. The roadmap presents the most important R&I knowledge gaps for each Soil Mission Objective, which were iden-tified in collaboration with stakeholders from all relevant sectors and based on the key findings of the project. To ensure that the R&I elements of the roadmap can effectively contribute to the desired transformation of land and soil management, the impact pathways approach was chosen as the analytical framework. The im-pact pathways are key component of the roadmap and describe several research actions that should be taken up to address the knowledge gaps and show what results we can expect from these actions that will lead to a short, medium- and finally long-term impact. The results show that to reach the eight Mission Objectives a common understanding of soil health is needed, as well as research and innovation in both natural sciences as well as social and economic spheres. The actions identified in the roadmap should be closely integrated. Future projects should focus more on finding systemic approaches to highlight synergies and minimise or avoid trade-offs while addressing the individual soil mission objectives.
New Borrowers in the Farmers Home Administration Operating Loan Program, 1965-66: Compared with New Borrowers Obtaining Loans from Banks and Production Credit Associations

description: Excerpt from the report Introduction: Through the years, the Federal Government has provided farmers with several credit programs. Since 1946, direct farm credit activities of the Government have been conducted by the Farmers Home Administration (FHA). During the more than 30 years that the FHA and its predecessor agencies have been in operation, various modifications have broadened the scope of these programs. Originally, loans were made to farmers conducting adequate family farming operations. After several years, this program was broadened to include farmers conducting less than adequate family farming operations. A more recent addition has been the provision of loans to low-income farm families for agricultural and nonagricultural purposes to generate at least a modest increase in their level of living. Other credit programs have also been added to provide assistance to rural people and communities.
On the universal $CH_0$ group of cubic hypersurfaces

description: We study the existence of a Chow-theoretic decomposition of the diagonal of a smooth cubic hypersurface, or equivalently, the universal triviality of its ${\rm CH}_0$-group. We prove that for odd dimensional cubic hypersurfaces or for cubic fourfolds, this is equivalent to the existence of a cohomological decomposition of the diagonal, and we translate geometrically this last condition. For cubic threefolds $X$, this turns out to be equivalent to the algebraicity of the minimal class $θ^4/4!$ of the intermediate Jacobian $J(X)$. In dimension $4$, we show that a special cubic fourfold with discriminant not divisible by $4$ has universally trivial ${\rm CH}_0$ group.

description: We consider decoding of vertically homogeneous interleaved sum-rank-metric codes with high interleaving order $s$, that are constructed by stacking $s$ codewords of a single constituent code. We propose a Metzner--Kapturowski-like decoding algorithm that can correct errors of sum-rank weight $t <= d-2$, where $d$ is the minimum distance of the code, if the interleaving order $s > t$ and the error matrix fulfills a certain rank condition. The proposed decoding algorithm generalizes the Metzner--Kapturowski(-like) decoders in the Hamming metric and the rank metric and has a computational complexity of $\tilde{O}(\max(n^3, n^2 s))$ operations in $\mathbb{F}_{q^m}$, where $n$ is the length of the code. The scheme performs linear-algebraic operations only and thus works for any interleaved linear sum-rank-metric code. We show how the decoder can be used to decode high-order interleaved codes in the skew metric. Apart from error control, the proposed decoder allows to determine the security level of code-based cryptosystems based on interleaved sum-rank metric codes.

description: Open access: where to go from here?
To advance with open access in the Netherlands, it is necessary to look at the qualitative aspects of open access in addition to the quantitative goals and ambitions. In this presentation, I highlighted the importance of enriching the national open access agenda by looking at different dimensions of open access. These dimensions include immediacy, community-driven initiatives, diamond open access, the critical role of open metadata, innovations in open peer review and the use of open licensing. Finally, the importance of recognising and rewarding open scholarly publishing practices will be highlighted.

description: In this survey we discuss spectral and quantum dynamical properties of discrete one-dimensional Schrödinger operators whose potentials are obtained by real-valued sampling along the orbits of an ergodic invertible transformation. After an introductory part explaining basic spectral concepts and fundamental results, we present the general theory of such operators, and then provide an overview of known results for specific classes of potentials. Here we focus primarily on the cases of random and almost periodic potentials.
