description: Im Hintergrund stehen historische Bibliotheksgebäude, deren Bestände durch ungünstige klimatische Verhältnisse in den Innenräumen ihrer der Erhaltung gefährdet sind. Damit Maßnahmen der Gebäudeleittechnik geplant werden können, ist die Aufnahme der Umweltgrößen über einen längeren Zeitraum erforderlich. Im speziellen zielen die Maßnahmen auf die Klimatechnik mit ihren Aufgaben der Heizungsregelung, Belüftungsanlagen. Ein Messsystem kann mit dem Mikrocontroller Beck >IPC@CHIP< realisiert werden. Das an der FH Fulda entwickelte Messsystem nimmt im Abstand von drei Minuten Messwerte von Lufttemperatur, Luftfeuchte, Luftdruck und UV-Intensität auf. Sie gelten als beeinflussende Größen der organischen Materialien des Fundus. Die Messwerte werden in einer elektronischen Schaltung vorverarbeitet und einem Mikrocontroller zugeführt. Dieser archiviert die Daten fortlaufend über einen Zeitraum bis zu sieben Jahren. Der Mikrocontroller ist mit seinem internen Flash-Speicher und der Ethernet-Schnittstelle in der Lage, die gesammelten Messwerte als Webserver zur Verfügung zu stellen. Wenn das Messsystem an das Internet angeschlossen wird, können die Klimaverläufe in einem herkömmlichen Internet-Browser dargestellt werden. Dafür wurde mit der Programmiersprache Java eine Visualisierungsoberfläche erstellt. Sie bietet die verschiedensten Möglichkeiten der Datenauswertung. Dazu gehört der Zugriff auf jeden einzelnen Messwert, auf Tages-, Monats- und Jahresmittelwerte und die Errechnung von Minima und Maxima. Der Flash-Speicher wurde auch dazu benutzt, Dokumentation und Bedienhinweise abzulegen, die somit über das Netzwerk abrufbar sind. Das gesamte Messsystem ist in ein Buch integriert und erfasst seit August 2002 die klimatischen Verhältnisse der Herzogin-Anna-Amalia-Bibliothek in Weimar. Nach den erfolgten Langzeitmessungen kann darüber entschieden werden, welchen Beitrag eine Gebäudeleittechnik mit integrierter Klimaregelung zur Werterhaltung der Gegenstände leisten kann.

description: Bell's inequality sets a strict threshold for how strongly correlated the outcomes of measurements on two or more particles can be, if the outcomes of each measurement are independent of actions undertaken at arbitrarily distant locations. Quantum mechanics, on the other hand, predicts that measurements on particles in entangled states can be more strongly correlated than Bell's inequality would allow. Whereas experimental tests conducted over the past half-century have consistently measured violations of Bell's inequality---consistent with the predictions of quantum mechanics---the experiments have been subject to one or more "loopholes," by means of which certain alternatives to quantum theory could remain consistent with the experimental results. This chapter reviews three of the most significant loopholes, often dubbed the "locality," "fair-sampling," and "freedom-of-choice" loopholes, and describes how recent experiments have addressed them.

description: PD-1 is a key negative regulator of CD8+ T cell activation and is highly expressed by exhausted T cells in cancer and chronic viral infection. Although PD-1 blockade can improve viral and tumor control, physiological PD-1 expression prevents immunopathology and improves memory formation. The mechanisms driving high PD-1 expression in exhaustion are not well understood and could be critical to disentangling its beneficial and detrimental effects. Here, we functionally interrogated the epigenetic regulation of PD-1 using a mouse model with deletion of an exhaustion-specific PD-1 enhancer. Enhancer deletion exclusively alters PD-1 expression in CD8+ T cells in chronic infection, creating a ‘sweet spot’ of intermediate expression where T cell function is optimized compared to wild-type and Pdcd1-knockout cells. This permits improved control of chronic infection without additional immunopathology. Together, these results demonstrate that tuning PD-1 via epigenetic editing can reduce CD8+ T cell dysfunction while avoiding excess immunopathology.

A simulation study of the deflection of the slab and at subgrade by a high-speed train
Creators: name: Alkhateeb, Mugdad
Publisher: name: London South Bank University
Year: 2021

description: As the demand for rapid transport and higher frequency rail services around the world is increasing, greater stresses are induced on the track, thus the necessity for a sustainable and durable railway structure is essential. To meet these demands it is seen that slab track construction is generally preferred for High-Speed Railways (HSR) as opposed to the conventional ballasted track as the slab track can sustain higher dynamic loading with less maintenance. In line with this research, a study on the development and application of a 3D structural model using ABAQUS software is carried out to evaluate the dynamic behaviour of HSR slab track. This research aims at evaluating the continuously fastened Balfour Beatty Embedded Rail Track System (ERS) and comparing it with the RHEDA (RTS) slab track system, which is discreetly fastened. The modelled rail tracks consist of a rail fastened onto a slab laid on a suitable foundation. The foundation consists of a Subbase Layer (HBL) placed on a Capping Layer (FPL) overlaying the subgrade soil. This thesis looks at the findings of dynamic analysis of various parameters which are affected during the high-speed passage of trains. Constant speeds are applied to a moving load as a part of dynamic analysis. Parametric studies are performed for CBL stiffness, soil stiffness and CBL thickness. The motion speeds are also changed to see its effect on the rail track. This study will shed light on the dynamic behaviour of ETS and RTS with changing parameters.

description: Current quantum simulation experiments are starting to explore non-equilibrium many-body dynamics in previously inaccessible regimes in terms of system sizes and time scales. Therefore, the question emerges which observables are best suited to study the dynamics in such quantum many-body systems. Using machine learning techniques, we investigate the dynamics and in particular the thermalization behavior of an interacting quantum system which undergoes a dynamical phase transition from an ergodic to a many-body localized phase. A neural network is trained to distinguish non-equilibrium from thermal equilibrium data, and the network performance serves as a probe for the thermalization behavior of the system. We test our methods with experimental snapshots of ultracold atoms taken with a quantum gas microscope. Our results provide a path to analyze highly-entangled large-scale quantum states for system sizes where numerical calculations of conventional observables become challenging.

description: In den zurückliegenden Jahren wurden an der Professur Massivbau I umfangreiche Untersuchungen zur Modellbildung und rechnerischen Erfassung des Tragverhaltens von Tragwerken und Tragwerkselementen aus Stahlbeton und Spannbeton unter Berücksichtigung von Rißbildungen und Plastizierungen durchgeführt. Diesen Untersuchungen liegt als einheitliches methodisches Konzept der mathematischen Problembeschreibung und Problemlösung die mathematische Optimierung zugrunde. Bereits anläßlich des IKM 1994 [1] hatte der Verfasser Gelegenheit, zusammenfassend über Ergebnisse bei der Anwendung der mathematischen Optimierung im Bereich der nichtlinearen Tragwerksanalyse zu berichten. Der vorliegende Beitrag, soll einen Überblick über seitdem untersuchte Problemkreise und dabei gewonnene Ergebnisse und Erfahrungen vermitteln. Bei der Anwendung der linearen und quadratischen Optimierung sind wegen der geforderten Linearität der Nebenbedingungen Vereinfachungen bei der Modellbildung des stahlbetonspezifischen Tragverhaltens unumgänglich. Besonders betroffen sind die Ansätze zur Beschreibungen des Materialverhaltens. Durch den Einsatz allgemeiner nichtlinearer mathematischer Optimierungsmethoden lässt sich eine methodisch bedingte Linearisierung des Berechnungsmodells umgehen....

description: Linear programming is used as a standard tool for optimising unit commitment or power flows in energy supply systems. For heat supply systems, however, it faces a relevant limitation: For them, energy yield depends on the output temperature, thus both quantities would have to be optimised simultaneously and the resulting problem is quadratic. As a solution, we describe a method working with discrete temperature levels. This paper presents mathematical models of various technologies and displays their potential in a case study focused on integrated residential heat and electricity supply. It is shown that the technique yields reasonable results including the choice of operational temperatures.

description: It has been shown that symmetries of moment functions of stochastic processes play an important role in identification of systems. They provide the group-theoretic method of choice of the model structure and model parameters. In the first stage the group-theoretic analysis of some fundamental concepts of stochastic dynamics: stochastic processes and functional series of Volterra-Wiener type has been undertaken. The analysis of group representations of the moment functions of order m for stochastic processes is the basic, original concept of the work. The following groups: symmetric Sm, special affine SAff(m), general linear GL(n, R), GL(n,C) and their subgroups play the main role in the models. In the second stage the informational entropy has been introduced as a measure of the randomness in the identified models. The group-theoretic approach underlines the unity of the nonlinear system identification and leads to useful engineering results in the range of the second-order (stochastic) theory.

description: Chromium triiodide is an intrinsically magnetic van der Waals material down to the single-layer limit. Here, we provide a first-principles description of finite-temperature magnetic and spectral properties of monolayer (ML) CrI$_3$ based on fully charge self-consistent density functional theory (DFT) combined with dynamical mean-field theory, revealing a formation of local moments on Cr from strong local Coulomb interactions. We show that the presence of local dynamical correlations leads to a modification of the electronic structure of ferromagnetically ordered CrI$_3$. In contrast to conventional DFT+$U$ calculations, we find that the top of the valence band in ML CrI$_3$ demonstrates essentially different orbital character for minority and majority spin states, which is closer to the standard DFT results. This leads to a strong spin polarization of the optical conductivity upon hole doping, which could be verified experimentally.

description: Die digitale Unterstützung der Planungsprozesse ist ein aktueller Forschungs- und Arbeitsschwerpunkt der Professur Informatik in der Architektur (InfAR) und der Juniorprofessur Architekturinformatik der Fakultät Architektur an der Bauhaus-Universität Weimar. Verankert in dem DFG Sonderforschungsbereich 524 >Werkzeuge und Konstruktionen für die Revitalisierung von Bauwerken< entstehen Konzepte und Prototypen für eine fachlich orientierte Planungsunterstützung. Als ein Teilaspekt wird in diesem Beitrag gezeigt, wie das Handaufmaß unter Einsatz modernen taktiler Erfassungsmethoden eine ganz neue Bedeutung für die Datenerfassung gewinnen kann. Das Potenzial der verschiedenen Verfahren zur Koordinatenbestimmung mit taktilen Werkzeugen wird evaluiert. Daraus wird eine Strategie entwickelt, die für die unterschiedlichen Notwendigkeiten im Planungsfortschritt den optimierten Einsatz der taktilen Erfassung in Kombination mit klassischen Erfassungsmethoden aufzeigt. Die Realisierbarkeit eines derartigen Konzeptes wird durch Fallstudien und mögliche Ablaufszenarien für einzelne Verfahren nachgewiesen. Durch die Integration taktiler Messverfahren in die Bestandserfassung kann erreicht werden, dass - relevante (Geometrie-) Informationen in ein umfassendes Bauwerksmodell integriert werden können, - die Bauaufnahme wieder im direkten Kontakt zum Bauaufnahmeobjekt erfolgen kann und - die Verfahren so einfach und leicht von allen Beteiligten eingesetzt werden können, um die Bauaufnahme und die Planung wieder miteinander zu verzahnen.

description: We present a high-bandwidth, lightweight, and nonlinear output tracking technique for soft actuators that combines parsimonious recursive layers for forward output predictions and online optimization using Newton-Raphson. This technique allows for reduced model sizes and increased control loop frequencies when compared with conventional RNN models. Experimental results of this controller prototype on a single soft actuator with soft positional sensors indicate effective tracking of referenced spatial trajectories and rejection of mechanical and electromagnetic disturbances. These are evidenced by root mean squared path tracking errors (RMSE) of 1.8mm using a fully connected (FC) substructure, 1.62mm using a gated recurrent unit (GRU) and 2.11mm using a long short term memory (LSTM) unit, all averaged over three tasks. Among these models, the highest flash memory requirement is 2.22kB enabling co-location of controller and actuator.

description: The well known phenomenon of avoided level crossing (ALC) can be perceived as a quantum analogue of the Thom's catastrophes in classical dynamical systems. One-dimensional Schrödinger equation is chosen for illustration. In constructive manner, a family of confining polynomial potentials is considered, characterized by the presence of an $N-$plet of high barriers separating the $(N+1)-$plet of deep valleys. The bifurcations of the long-time classical equilibria are shown paralleled by the ALCs in the quantum low-lying spectra. Every tunneling-controlled fine-tuned switch of dominance between the valleys is finally interpreted as a change of the topological structure of the probability density representing a genuine quantum relocalization catastrophe.

description: Risk to persons caused by gravitationally driven site-specific natural hazards along traffic routes is frequently reduced with Early Warning Systems (EWS). To identify an optimal risk reduction strategy, decision-makers should be able to quantify the effectiveness and costs achieved with EWS and compare both to alternative mitigation measures. A recognized framework approach for quantifying the effectiveness of EWS is currently lacking. We provide such a framework approach, which includes six steps that enable a structured quantification of the effectiveness, from the reliability of the EWS. To this end, site specific EWS are distinguished in two classes and the reliability analyses are conducted according to specific needs with Bayesian Networks (BN).

BUDGETING IN TIMES OF CRISIS: HOW ORGANIZATIONS AND GOVERNMENTS ADAPT BUDGET STRATEGIES DURING ECONOMIC RECESSIONS AND GLOBAL PANDEMICS
Creators: name: Mbonigaba Celestin
Publisher: name: Zenodo
Year: 2018

description: This study examines how organizations and governments adapted their budgeting strategies in response to economic crises and global pandemics between 2012 and 2016, a period marked by significant global financial instability. The research highlights the need for adaptive budgeting strategies during economic downturns and pandemics, exploring the fiscal challenges and interventions employed by both public and private sectors. Using secondary data from global economic and fiscal reports, the study employed statistical techniques such as regression analysis, chi-square tests, and correlation analysis to assess the relationship between fiscal policies and economic outcomes, particularly focusing on the impact of austerity measures versus countercyclical policies. Major findings revealed a negative correlation between austerity measures and economic recovery, with austerity leading to higher unemployment and prolonged recessions in countries like Greece and Portugal. In contrast, countries implementing countercyclical strategies, such as the US and Brazil, saw moderate economic recovery. The overall correlation coefficient between fiscal policy and recovery outcomes was found to be 0.56, indicating a moderate positive relationship. Based on these findings, the study recommends the adoption of flexible and crisis-responsive budgeting frameworks that balance short-term stimulus and long-term fiscal sustainability to enhance resilience against future crises.

description: We consider a particle transport process in a one-dimensional system with a thin membrane, described by a normal diffusion equation. We consider two boundary conditions at the membrane that are linear combinations of integral operators, with time dependent kernels, which act on the functions and their spatial derivatives define on both membrane surfaces. We show how boundary conditions at the membrane change the temporal evolution of the first and second moments of particle position distribution (the Green's function) which is a solution to normal diffusion equation. As these moments define the kind of diffusion, an appropriate choice of boundary conditions generates the moments characteristic for subdiffusion. The interpretation of the process is based on a particle random walk model in which the subdiffusion effect is caused by anomalously long stays of the particle in the membrane.

description: General relativistic effects in the spacetime around the massive astrophysical objects can be captured using a spinning test gyro orbiting around the object in a circular geodesic. This article discusses how the tidal disruption due to a companion object affects the precession frequency of a spinning gyro orbiting around a compact astrophysical object. The precession frequency is studied in a region of space around the central object using a perturbative approach. In this study, the central object is either a neutron star or a white dwarf. The gyro is any planetary or asteroid-like object orbiting the neutron star or a white dwarf. Moreover, the companion object that causes the tidal field can be a neutron star, white dwarf, a black hole, or a main-sequence star. The tidal effect significantly affects the spacetime around the host star, which affects the gyro precession frequency. The gyro's precession frequency increases with the mass of the companion object and decreases as the separation between the host star and the companion star increases. The tidal effect also varies with the stiffness of the equation of state of matter describing the neutron star. We also find that the tidal field affects the spacetime around a white dwarf more than that of the neutron star.

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

description: The application of hierarchical models for assessing the compressive strength of structural masonry is investigated. Based on current codified models the distribution of compressive strengths within an ensemble of masonry wall specimens is related to the statistical properties of the populations of brick units and mortar used. The parameters of this relation are calibrated with test data acquired at ETH Zürich. This approach allows for heterogeneous material modeling, consistent uncertainty management and optimal information processing. Costly compression tests of full-size masonry and inexpensive tests of brick and mortar samples are jointly utilized for learning about the masonry wall characteristics.

Zur Minimierung des Rechenaufwandes der Lebensdauer-untersuchung wurden a priori einige Systemparameter anhand von Parameterstudien im Hinblick auf ihre dynamische Wirkung maßgebend festgelegt. In einer darauf aufbauenden Betriebsfestigkeitsuntersuchung wurden die Schädigungseinträge in einer Rahmenecke infolge von jeweils einzelnen Pulslastereignissen berechnet und in einer Datenbasis abgelegt. Eine abschließende Distance-Controlled Monte Carlo Simulation der Pulsprozesse über einen maximalen Zeitraum von 100 Jahren überführte die Realisationen der einzelnen Pulslasten anhand der Datenbasis in Teilschädigungen, welche nach der Palmgren/Miner-Hypothese zu einer Gesamtschädigung aufsummiert wurden. Der Einfluss der Kranlasten auf den Entwurf von Stahlhallen wurde durch den Vergleich der berechneten Lebensdauer und der planmäßig vorgegebenen Nutzungsdauer quantifiziert.

description: Exchange bias is a phenomenon critical to solid-state technologies that require spin valves or non-volatile magnetic memory. The phenomenon is usually studied in the context of magnetic interfaces between antiferromagnets and ferromagnets, where the exchange field of the former acts as a means to pin the polarization of the latter. In the present study, we report an unusual instance of this phenomenon in the topological Weyl semimetal Co3Sn2S2, where the magnetic interfaces associated with domain walls suffice to bias the entire ferromagnetic bulk. Remarkably, our data suggests the presence of a hidden order parameter whose behavior can be independently tuned by applied magnetic fields. For micron-size samples, the domain walls are absent, and the exchange bias vanishes, suggesting the boundaries are a source of pinned uncompensated moment arising from the hidden order. The novelty of this mechanism suggests exciting opportunities lie ahead for the application of topological materials in spintronic technologies.

METHODOLOGY FOR DEVELOPING AND INTEGRATING SOFTWARE PRODUCTS

description: Contemporary education systems increasingly rely on digital formats to make teaching, knowledge reinforcement, assessment, and professional development more efficient. In this setting, the software products being developed (platforms, web applications, mobile apps, online testing systems, etc.) can radically transform the teaching process. However, merely creating a piece of software is insufficient to achieve genuine impact – it also needs to be sensibly integrated into the learning environment and implemented in accordance with sound didactic methodology. Equally relevant are questions about how commonly used tools such as Learning Management Systems (LMS) or online testing platforms work in practice and what technical and methodological requirements they must meet.
The split and approximate split property in 2D systems: stability and absence of superselection sectors

description: The split property of a pure state for a certain cut of a quantum spin system can be understood as the entanglement between the two subsystems being weak. From this point of view, we may say that if it is not possible to transform a state $ω$ via sufficiently local automorphisms (in a sense that we will make precise) into a state satisfying the split property, then the state $ω$ has a long-range entanglement. It is well known that in 1D, gapped ground states have the split property with respect to cutting the system into left and right half-chains. In 2D, however, the split property fails to hold for interesting models such as Kitaev's toric code. In fact, we will show that this failure is the reason that anyons can exist in that model. There is a folklore saying that the existence of anyons, like in the toric code model, implies long-range entanglement of the state. In this paper, we prove this folklore in an infinite dimensional setting. More precisely, we show that long-range entanglement, in a way that we will define precisely, is a necessary condition to have non-trivial superselection sectors. Anyons in particular give rise to such non-trivial sectors. States with the split property for cones, on the other hand, do not admit non-trivial sectors. A key technical ingredient of our proof is that under suitable assumptions on locality, the automorphisms generated by local interactions can be 'approximately factorized': they can be written as the tensor product of automorphisms localized in a cone and its complement respectively, followed by an automorphism acting near the 'boundary' of $Λ$, and conjugation with a unitary. This result may be of independent interest. This technique also allows us to prove that the approximate split property, a weaker version of the split property that is satisfied in e.g. the toric code, is stable under applying such automorphisms.

THE EFFECTIVENESS OF BEYOND BUDGETING MODELS: CAN BUSINESSES ABANDON TRADITIONAL BUDGETING FOR MORE AGILE AND REAL-TIME FINANCIAL PLANNING?
Creators: name: Mbonigaba Celestin
Publisher: name: Zenodo
Year: 2017

description: This study investigates the effectiveness of Beyond Budgeting models in comparison to traditional budgeting methods, focusing on businesses operating between 2012 and 2016. Traditional budgeting has been criticized for its rigidity and inability to adapt to dynamic market conditions, prompting businesses to explore more flexible, real-time financial planning models. The research evaluates how adopting Beyond Budgeting influences financial flexibility, decision-making efficiency, and overall business performance. Utilizing a descriptive research design and secondary data, the study employed statistical techniques including t-tests, chi-square tests, and correlation analysis to assess the impact. Major findings reveal that companies adopting Beyond Budgeting models experienced a significant increase in financial flexibility, with a p-value of less than 0.05, and a higher decision-making efficiency, with a correlation coefficient of +0.87. The research concludes that Beyond Budgeting models substantially enhance adaptability and decision-making capabilities in dynamic environments. However, the study highlights the challenges businesses face during the transition, such as resistance to change and data integration difficulties. It recommends that organizations invest in training and technology to overcome these barriers and facilitate a smoother shift to dynamic financial systems.

description: The axion provides a solution for the strong CP problem and is one of the leading candidates for dark matter. This paper proposes an axion detection scheme based on quantum nondemolition detection of magnon, i.e., quanta of collective spin excitations in solid, which is expected to be excited by the axion-electron interaction predicted by the Dine-Fischer-Srednicki-Zhitnitsky (DFSZ) model. The prototype detector is composed of a ferrimagnetic sphere as an electronic spin target and a superconducting qubit. Both of these are embedded inside a microwave cavity, which leads to a coherent effective interaction between the uniform magnetostatic mode in the ferrimagnetic crystal and the qubit. An upper limit for the coupling constant between an axion and an electron is obtained as $g_{aee}<2.6\times10^{-6}$ at the 95% confidence level for the axion mass of $33.117$$μ$eV $

description: A novel framework for concurrently simulating strong motions and tsunami waves is developed. It explicitly considers the dependency of both hazard processes on common source characteristics. The earthquake source properties are modeled stochastically, incorporating various sources of uncertainties. The developed computational procedure is applied to the Mw9 2011 Tohoku, Japan earthquake. Numerical examples of the coupled simulations of strong motion and tsunami highlight the major impact of source characteristics on strong motion and tsunami hazard parameters. The investigations also provide valuable insights in understanding the spatial impact of cascading earthquake hazards. Such an advanced numerical tool is necessary for assessing the performance of buildings and coastal infrastructure that are subjected to cascading hazards triggered by large subduction earthquakes.
