description: We perform numerical simulation based on the time-dependent mean-field Gross-Pitaevskii equation to understand some aspects of a recent experiment by Donley et al. on the dynamics of collapsing and exploding Bose-Einstein condensates of $^{85}$Rb atoms. They manipulated the atomic interaction by an external magnetic field via a Feshbach resonance, thus changing the repulsive condensate into an attractive one and vice versa. In the actual experiment they changed suddenly the scattering length of atomic interaction from positive to a large negative value on a pre-formed condensate in an axially symmetric trap. Consequently, the condensate collapses and ejects atoms via explosion. We find that the present mean-field analysis can explain some aspects of the dynamics of the collapsing and exploding Bose-Einstein condensates.

title: Automation for camera-only 6D object detection
Creators: name: Rojtberg, Pavel
Publisher: name: UNSPECIFIED
Year: 2021

description: Today a widespread deployment of Augmented Reality (AR) systems is only possible by means of computer vision frameworks like ARKit and ARCore, which abstract from specific devices, yet restrict the set of devices to the respective vendor. This thesis therefore investigates how to allow deploying AR systems to any device with an attached camera. One crucial part of an AR system is the detection of arbitrary objects in the camera frame and naturally accompanying the estimation of their 6D-pose. This increases the degree of scene understanding that AR applications require for placing augmentations in the real world. Currently, this is limited by a coarse segmentation of the scene into planes as provided by the aforementioned frameworks. Being able to reliably detect individual objects, allows attaching specific augmentations as required by e.g. AR maintenance applications. For this, we employ convolutional neural networks (CNNs) to estimate the 6D-pose of all visible objects from a single RGB image. Here, the addressed challenge is the automated training of the respective CNN models, given only the CAD geometry of the target object. First, we look at reconstructing the missing surface data in real-time before we turn to the more general problem of bridging the domain gap between the non-photorealistic representation and the real world appearance. To this end, we build upon generative adversarial network (GAN) models to formulate the domain gap as an unsupervised learning problem. Our evaluation shows an improvement in model performance, while providing a simplified handling compared to alternative solutions. Furthermore, the calibration data of the used camera must be known for precise pose estimation. This data, again, is only available for the restricted set of devices, that the proprietary frameworks support. To lift this restriction, we propose a web-based camera calibration service that not only aggregates calibration data, but also guides users in the calibration of new cameras. Here, we first present a novel calibration-pose selection framework that reduces the number of required calibration images by 30% compared to existing solutions, while ensuring a repeatable and reliable calibration outcome. Then, we present an evaluation of different user-guidance strategies, which allows choosing a setting suitable for most users. This enables even novice users to perform a precise camera calibration in about 2 minutes. Finally, we propose an efficient client-server architecture to deploy the aforementioned guidance on the web, making it available to the widest possible range of devices. This service is not restricted to AR systems, but allows the general deployment of computer vision algorithms on the web that rely on camera calibration data, which was previously not possible. These elements combined, allow a semi-automatic deployment of AR systems with any camera to detect any object.
Skirmishes: With Friends, Enemies, and Neutrals
Creators: name: Harman, Graham
Publisher: name: punctum books
Year: 2020

description: One of the fifty most influential living philosophers, a “self-promoting charlatan” (Brian Leiter), and the orchestrator of an “online orgy of stupidity” (Ray Brassier). In Skirmishes: With Friends, Enemies, and Neutrals, Graham Harman responds with flair and wit to some of his best-known critics and fellow travelers. Pulling no punches, Harman gives a masterclass in philosophical argumentation by dissecting, analyzing, and countering their criticism, be it from the Husserlian, Heideggerian, or Derridean corner. At the same time, Skirmishes provides an excellent introduction to the hottest debates in Speculative Realism and Object-Oriented Ontology, a speculative style of philosophy long foreclosed by the biases of mainstream continental thought, but which has turned in recent years into one of the most encompassing philosophies of our time, with a major impact on the arts, humanities, and architecture. Part One considers four prominent books on speculative realism. In dialogue with Tom Sparrow’s The End of Phenomenology, Harman expresses agreement with Sparrow’s critique while taking issue with Lee Braver’s “transgressive realism” as not realist enough. Turning to Steven Shaviro’s The Universe of Things, Harman defends his own object-oriented model against Shaviro’s brand of process philosophy, while also engaging in side-debate with Levi R. Bryant’s distinction between virtual proper being and local manifestations. In the third chapter, on Peter Gratton’s Speculative Realism: Problems and Prospects, Harman opposes the author’s attempt to use Derridean notions of time and difference against Speculative Realism, in what amounts to his most extensive engagement with Derrida to date. Chapter Four gives us Harman’s response to Peter Wolfendale’s massive polemic in Object-Oriented Philosophy, which he shows is based on a failed criticism of Harman’s reading of Heidegger and a grumpy commitment to rationalist kitsch. Part Two responds to a series of briefer criticisms of object-oriented ontology. When Alberto Toscano accuses Harman and Bruno Latour of “neo-monadological” and anti-scientific thinking, Harman responds that the philosophical factors pushing Leibniz into monadology are still valid today. When Christopher Norris mocks Harman for seeing merit in the occasionalist school, he shows why Norris’s middle-of-the-road scientific realism misses the point. In response to Dan Zahavi’s contention that phenomenology has little to learn from speculative realism, Harman exposes the holes in Zahavi’s reasoning. In a final response, Harman gives a point-by-point answer to Stephen Mulhall’s critical foray in the London Review of Books. Amidst these lively debates, Harman sheds new light on what he regards as the central bias of philosophical modernism, which he terms the taxonomical standpoint. It is a book sure to provoke lively controversy among both friends and foes of object-oriented thought.

description: In advanced medication, drug-loaded polymeric nanoparticles (NPs) appeared as a novel drug delivery system with lots of advantages over conventional medicines. Despite all the advantages, NPs do not gain popularity for manufacturing hurdles. The study focused on the formulation difficulties and implementation of statistical design to establish an effective model for manufacturing NPs. In this study, physico-chemical properties of the drug and polymer (PLGA) were incorporated to understand the mechanistic insights of nanoformulations. Primarily, the process controlling parameters were screened by Plackett–Burman design and the critical process parameters (Cpp) were further fabricated by Box–Behnken design (BBD). The TLM-PLGA-NPs (telmisartan loaded PLGA NPs) exhibited particle size, encapsulation efficiency and zeta potential of 232.4 nm, 79.21% and −9.92 mV respectively. The NPs represented drug loading of 76.31%. Korsmeyer–Peppas model (R2 = 0.925) appeared to be the best fitted model for in vitro release kinetics of NPs. The model identified Fickian diffusion of TLM from the polymeric nanoparticles. The ANOVA results of variables indicate that BBD is a suitable model for the development of polymeric NPs. The study successfully identified and evaluated the correlation of significant parameters that were directly or indirectly influencing the formulations which deliberately produce desired nanoparticles with the help of Statistical design.

Possibility to study pentaquark states $P_{c}(4312), P_{c}(4440)$, and $P_{c}(4457)$ in $γp\rightarrow J/ψp$ reaction

description: Inspired by the observation of the pentaquark states $P_{c}(4312),P_{c}(4440)$ and $P_{c}(4457)$ at LHCb, photoproduction of these three $P_{c}$ states via the interaction $γp\rightarrow J/ψp$ is investigated in an effective Lagrangian approach. The $t$-channel Pomeron exchange diffractive process is considered as the main background for the $J/ψ$ photoproduction. The numerical results show that the theoretical cross section, which is calculated by assuming a branching ratio $Br[P_{c}\rightarrow J/ψp]\simeq 3\%$, is consistent with the existing experimental data of the $ γp\rightarrow J/ψp$ process. With such a branching ratio, if experimental precision reaches 0.1 nb within a bin of 100 MeV for photon energy, two peaks are expected to be obviously observed in the $J/ψ$ photoproduction. To observe the two-peak structure from $P_{c}(4440)$ and $ P_{c}(4457)$, higher precision, about 0.1nb/10 MeV, is required to distinguish two close pentaquarks. If the physical branching ratio is larger, the requirement of experimental precision will be reduced. The differential cross sections for reaction $γp\rightarrow J/ψp$ are also present. It is found that the $t$-channel Pomeron exchange provides a sharp increase at extreme forward angles and gives a sizable contribution at most energy points, while the contributions from the $s$-channel $P_{c}$ exchanges play important roles at threshold energies. The experimental measurement of the $γp\rightarrow J/ψp$ process in the near-threshold energy region around $E_{γ}\simeq 9.4-10.5$ GeV is suggested, and is accessible at CEBAF@JLab and COMPASS.

Getting rid of nonlocality from quantum physics

Publisher: name: arXiv
Year: 2019
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: This paper is aimed to dissociate nonlocality from quantum theory. We demonstrate that the tests on violation of the Bell type inequalities are simply statistical tests of local incompatibility of observables. In fact, these are tests on violation of {\it the Bohr complementarity principle.} Thus, the attempts to couple experimental violations of the Bell type inequalities with "quantum nonlocality" is really misleading. These violations are explained in the quantum theory as exhibitions of incompatibility of observables for a single quantum system, e.g., the spin projections for a single electron or the polarization projections for a single photon. Of course, one can go beyond quantum theory with the hidden variables models (as was suggested by Bell) and then discuss their possible nonlocal features. However, conventional quantum theory is local.

description: A unified understanding of interfacial thermal transport is missing due to the complicated nature of interfaces which involves complex factors such as interfacial bonding, interfacial mixing, surface chemistry, crystal orientation, roughness, contamination, and interfacial disorder. This is especially true for metal nonmetal interfaces which incorporate multiple fundamental heat transport mechanisms such as elastic and inelastic phonon scattering as well as electron phonon coupling in the metal and across the interface. All these factors jointly affect thermal boundary conductance (TBC). As a result, the experimentally measured interfaces may not be the same as the ideally modelled interfaces, thus obfuscating any conclusions drawn from experimental and modeling comparisons. This work provides a systematic study of interfacial thermal conductance across well controlled and ultraclean epitaxial (111) Al parallel (0001) sapphire interfaces, known as harmonic matched interface. A comparison with thermal models such as atomistic Green s function (AGF) and a nonequilibrium Landauer approach shows that elastic phonon scattering dominates the interfacial thermal transport of Al sapphire interface. By scaling the TBC with the Al heat capacity, a nearly constant transmission coefficient is observed, indicating that the phonons on the Al side limits the Al sapphire TBC. This nearly constant transmission coefficient validates the assumptions in AGF and nonequilibrium Landauer calculations. Our work not only provides a benchmark for interfacial thermal conductance across metal nonmetal interfaces and enables a quantitative study of TBC to validate theoretical thermal carrier transport mechanisms, but also acts as a reference when studying how other factors impact TBC.

description: We show how the generalised (or skewed) parton distributions of the proton, H(x, xi; k_t^2, mu^2), unintegrated over the partonic transverse momenta, can be calculated from the known conventional parton distributions, q(x, mu^2) and g(x, mu^2), for small values of the skewedness parameter xi. We demonstrate the procedure by numerically evaluating the skewed unintegrated gluon. We also provide a simple approximate phenomenological form of the distribution, which may be used to make more rapid predictions of observables.

title: Families of Chiral Two- plus Three-Nucleon Interactions for Accurate Nuclear Structure Studies
Creators: name: Hüther, Thomas
Publisher: name: UNSPECIFIED
Year: 2021

description: Chiral effective field theory allows for a systematically improvable construction of nuclear interactions and currents rooted in quantum chromodynamics (QCD). In this thesis we propose families of chiral nucleon-nucleon (NN) plus three-nucleon (3N) interactions and develop a framework to incorporate nuclear exchange-current contributions to the $M1$ operator in importance-truncated no-core shell model (IT-NCSM) calculations. The interaction families base on the Entem, Machleidt and Nosyk NN interactions, which are supplemented at next-to-next-to-leading order (N$^2$LO) and next-to-next-to-next-to-leading order (N$^3$LO) with 3N interactions consistent in chiral order, non-local regulator, and cutoff values. We study the dependence of observables of light- and medium-mass nuclei on the 3N low-energy constants (LECs). Based on the results, we propose two alternative optimization procedures for the LECs. One optimizes the ground-state energies of $^{3}$H and $^{4}$He and the other the ground-state energies of $^{3}$H and $^{16}$O. The performance of both interaction families is explored for ground-state energies and radii of light- and medium-mass nuclei as well as for spectra of p-shell nuclei. In these calculations, we give a fully estimation of the uncertainties for both the many-body method and the interaction. The uncertainties due to the chiral truncation are estimated with a state-of-the-art approach rooted in Bayesian statistics. Both interaction families lead to robust results for the considered observables. In particular, the inclusion of the ground-state energy of $^{16}$O in the optimization procedure leads to energies and radii, which reproduce the experimental values up to the nickel isotopes well. For precision studies of electromagnetic observables like multipole moments and transition strengths, we need in addition to an accurate interaction also consistent exchange currents. In this work, we develop the necessary framework to include exchange-current contributions to the $M1$ operator in IT-NCSM calculations. This comprises the correct treatment in the similarity renormalization group (SRG) as well as the transformation into a suitable single-particle basis representation. This leads to the first fully chiral determination of the magnetic dipole moment of the ground state of $^{6}$Li as well as the magnetic dipole transition strength from the first $0^+$ to the $1^+$ ground state of $^{6}$Li including the next-to leading order (NLO) current contribution to the $M1$ operator. This study shows that both the consistent treatment in the SRG and the exchange-current contribution to the $M1$ operator are important to match theory and experiment.

description: In the designed compounds, either a biarylamide or biarylurea moiety or an N-substituted piperazine motif was linked to position 1 of the phthalazine core. The anti-proliferative activity of the synthesised compounds revealed that eight compounds (6b, 6e, 7b, 13a, 13c, 16a, 16d and 17a) exhibited excellent broad spectrum cytotoxic activity in NCI 5-log dose assays against the full 60 cell panel with GI50 values ranging from 0.15 to 8.41 µM. Moreover, the enzymatic assessment of the synthesised compounds against VEGFR-2 tyrosine kinase showed the significant inhibitory activities of the biarylureas (12b, 12c and 13c) with IC50s of 4.4, 2.7 and 2.5 μM, respectively, and with 79.83, 72.58 and 71.6% inhibition of HUVEC at 10 μM, respectively. Additionally, compounds (7b, 13c and 16a) were found to induce cell cycle arrest at S phase boundary. Compound 7b triggered a concurrent increase in cleaved caspase-3 expression level, indicating the apoptotic-induced cell death.

description: The nature of the dark matter in the halo of our Galaxy is still largely unknown. The microlensing events found so far towards the Large Magellanic Cloud suggest that at most about 20% of the halo dark matter is in the form of MACHOs (Massive Astrophysical Compact Halo Objects). The dark matter could also, at least partially, consist of cold molecular clouds (mainly $H_2$). Another possibility is that WIMPs (Weakly Interacting Massive Particles) make up the dark matter and that, due to annihilition processes, they show up through gamma-ray emission.

Search for a heavy charged boson in events with a charged lepton and missing transverse momentum from $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector

description: A search for a heavy charged-boson resonance decaying into a charged lepton (electron or muon) and a neutrino is reported. A data sample of 139 fb$^{-1}$ of proton-proton collisions at $\sqrt{s} = 13$ TeV collected with the ATLAS detector at the LHC during 2015-2018 is used in the search. The observed transverse mass distribution computed from the lepton and missing transverse momenta is consistent with the distribution expected from the Standard Model, and upper limits on the cross section for $pp \to W^\prime \to \ellν$ are extracted ($\ell = e$ or $μ$). These vary between 1.3 pb and 0.05 fb depending on the resonance mass in the range between 0.15 and 7.0 TeV at 95% confidence level for the electron and muon channels combined. Gauge bosons with a mass below 6.0 TeV and 5.1 TeV are excluded in the electron and muon channels, respectively, in a model with a resonance that has couplings to fermions identical to those of the Standard Model $W$ boson. Cross-section limits are also provided for resonances with several fixed $Γ/ m$ values in the range between 1% and 15%. Model-independent limits are derived in single-bin signal regions defined by a varying minimum transverse mass threshold. The resulting visible cross-section upper limits range between 4.6 (15) pb and 22 (22) ab as the threshold increases from 130 (110) GeV to 5.1 (5.1) TeV in the electron (muon) channel.

description: Knotenbleche stellen vor allem in Fachwerkkonstruktionen und Verbandsanschlüssen ein sehr wichtiges Verbindungselement dar. Werden die in den Konstruktionen verwendeten Profile auf Druck belastet, so sind nicht nur diese, sondern auch die Knotenbleche selbst stabilitätsgefährdet. Der entstehende Stabwerkszug aus Blech-Profil-Blech kann hierbei aufgrund der veränderlichen Steifigkeit auf verschiedene Arten knicken. Nach aktuell gültiger Norm gibt es hierfür kein realitätsnahes Bemessungskonzept, weshalb diese Problematik in den letzten Jahren vermehrt aufgegriffen wurde (siehe hierzu u. a. VETTE, ABEL, LIU). In den entsprechenden Arbeiten geht es jedoch zumeist um ein mögliches erweitertes Nachweisverfahren im Rahmen der DIN EN 1993-1-1, bei dem die Steifigkeitsänderung berücksichtigt wird. Die Knotenbleche sind hierbei Teil des Stabwerkzuges und werden adäquat modelliert. Eine genaue Untersuchung dieser Bleche bezüglich ihrer absoluten Traglast wurde dabei jedoch nicht durchgeführt, weshalb sich die vorliegende Masterarbeit mit dieser Thematik beschäftigt. Mit Hilfe des kommerziellen Finiten-Element-Programmes ANSYS soll eine Traglastuntersuchung verschiedener Geometrien durchgeführt werden. Hierbei kann eine eventuell günstige Plattenwirkung durch einen zweiachsigen Lastabtrag bei den übereck gelagerten Knotenblechen berücksichtigt werden. Fraglich ist, ob diese Bleche überkritische Traglastreserven – vergleichbar zu Platten – entwickeln können. Eine Herausforderung stellt jedoch die Implementierung der Bleche in einem FE-Modell dar. Die gewählten Lagerungsbedingungen und die angesetzten Imperfektionen haben einen entscheidenden Einfluss auf das Resultat der Untersuchung. Eine Validierung des gewählten Modells ist daher notwendig.

description: Political scientists face problems when assessing a leader’s impact: how can we know that a policy outcome or institutional change is caused by leadership? This article argues that in addition to relying on comparisons and counterfactuals, we need to trace the causal mechanisms by which leadership affects outcomes. Therefore, the article proposes a way to trace leadership and applies it to two cases of EU crisis management: the European Central Bank’s role in announcing Outright Monetary Transactions in the eurozone crisis, and Germany’s role in shaping the EU’s response to the Ukraine crisis. Systematic process-tracing shows that both actors provided leadership ‘by default’. However, while the ECB had to combine the provision of knowledge with unilateral action in order to overcome the eurozone crisis, Germany could use manifold bargaining-based strategies and thus became the EU’s de facto agenda setter and main representative in managing the Ukraine crisis.

description: The Standard Model flavor structure can be explained in theories where the fermions are localized on different points in a compact extra dimension. We show that models with two bulk scalars compactified on an orbifold can produce such separations in a natural way. We study the shapes and overlaps of the fermion wave functions. We show that, generically, realistic models of Gaussian overlaps are unnatural since they require very large Yukawa couplings between the fermions and the bulk scalars. We give an example of a five dimensional two scalar model that accounts naturally for the observed quark masses, mixing angles and CP violation.

description: We carry out a comprehensive analysis of the nonminimal supersymmetric standard model (NMSSM) with baryon and lepton number violation. We catalogue the baryon and lepton number violating dimension four and five operators of the model. We then study the renormalization group evolution and infrared stable fixed points of the Yukawa couplings and the soft supersymmetry breaking trilinear couplings of this model with baryon and lepton number (and R-parity) violation involving the heaviest generations. We show analytically that in the Yukawa sector of the NMSSM there is only one infrared stable fixed point. This corresponds to a non-trivial fixed point for the top-, bottom-quark Yukawa couplings and the $B$ violating coupling $λ_{233}''$, and a trivial one for all other couplings. All other possible fixed points are either unphysical or unstable in the infrared region. We also carry out an analysis of the renormalization group equations for the soft supersymmetry breaking trilinear couplings, and determine the corresponding fixed points for these couplings. We then study the quasi-fixed point behaviour, both of the third generation Yukawa couplings and the baryon number violating coupling, and those of the soft supersymmetry breaking trilinear couplings. From the analysis of the fixed point behaviour, we obtain upper and lower bounds on the baryon number violating coupling $λ_{233}''$, as well as on the soft supersymmetry breaking trilinear couplings. Our analysis shows that the infrared fixed point behavior of NMSSM with baryon and lepton number violation is similar to that of MSSM.

description: The method for analytic evaluation of four-particle integrals, proposed by Fromm and Hill, is generalized to include complex exponential parameters. An original procedure of numerical branch tracking for multiple valued functions is developed. It allows high precision variational solution of the Coulomb four-body problem in a basis of exponential-trigonometric functions of interparticle separations. Numerical results demonstrate high efficiency and versatility of the new method.

description: In the framework of the Constrained Minimal Supersymmetric Standard Model (CMSSM) we discuss the impact of the recent experimental information, especially from E821 Brookhaven experiment on $g_μ-2$ along with the light Higgs boson mass bound from LEP, to the Dark Matter direct searches. Imposing these experimental bounds, the maximum value of the spin-independent neutralino-nucleon cross section turns out to be of the order of $10^{-8}$ pb for large values of $\tanβ$ and low $M_{1/2}, m_0$. The effect of the recent experimental bounds is to decrease the maximum value of the cross section by about an order of magnitude, demanding the analogous sensitivity from the direct Dark Matter detection experiments.

description: Aims. We use Hermite splines to interpolate pressure and its derivatives simultaneously, thereby preserving mathematical relations between the derivatives. The method therefore guarantees that thermodynamic identities are obeyed even between mesh points. In addition, our method enables an estimation of the precision of the interpolation by comparing the Hermite-spline results with those of frequent cubic (B-) spline interpolation. Methods. We have interpolated pressure as a function of temperature and density with quintic Hermite 2D-splines. The Hermite interpolation requires knowledge of pressure and its first and second derivatives at every mesh point. To obtain the partial derivatives at the mesh points, we used tabulated values if given or else thermodynamic equalities, or, if not available, values obtained by differentiating B-splines. Results. The results were obtained with the grid of the SAHA-S equation-of-state (EOS) tables. The maximum $lg P$ difference lies in the range from $10^{-9}$ to $10^{-4}$, and $Γ_1$ difference varies from $10^{-9}$ to $10^{-3}$. Specifically, for the points of a solar model, the maximum differences are one order of magnitude smaller than the aforementioned values. The poorest precision is found in the dissociation and ionization regions, occurring at $T \sim 1.5\cdot 10^3 - 10^5$ K. The best precision is achieved at higher temperatures, $T>10^5$ K. To discuss the significance of the interpolation errors we compare them with the corresponding difference between two different equation-of-state formalisms, SAHA-S and OPAL 2005. We find that the interpolation errors of the pressure are a few orders of magnitude less than the differences from between the physical formalisms, which is particularly true for the solar-model points.

description: Objective: To study the difference in incidence and risk of fragility fractures between rheumatoid arthritis (RA) patients followed up early in the disease and the general population in Sweden; and the fracture risk changes in RA patients diagnosed in the 1990s and 2000s because of earlier, more potent pharmacological treatment in the later period. Method: Patients with early RA were recruited from the BARFOT cohort, a Swedish multicentre observational study of early RA patients (n = 2557). All patients fulfilled 1987 American College of Rheumatology criteria and were included between 1992 and 2006. Each patient was matched by gender, age, and residential area with four controls from the general population (n = 10 228). Fractures of forearm, upper arm, and hip were identified by ICD-9 and ICD-10 codes through Swedish national medical registries. Results: During follow-up of 12.9 ± 4.7 years (mean ± sd), 14% (n = 470) of RA patients and 11% (n = 1418) of controls experienced a fracture (p Conclusion: We observed an increased risk of fragility fractures in RA patients diagnosed in both the 1990s and 2000s, despite patients in the 2000s obtaining potent pharmacological treatment early in the disease.
title: Numerical Analyzes and Experimental Investigations of Air Foil Journal Bearings
Creators: name: Mahner, Marcel
Publisher: name: UNSPECIFIED

description: Self-acting air foil journal bearings are an important component in high-speed, oil-free turbomachinery applications. For rotors supported in air foil journal bearings, subharmonic vibrations and fluid-film induced instabilities of the rotor-bearing system may occur. In order to decrease the amplitude of these subharmonic vibrations and to increase the onset speed of the fluid-film induced instabilities, a preload is often introduced in air foil journal bearings. In this study, the effect of an assembly preload on the thermo-elasto-gasdynamic behavior of a three-pad air foil journal bearing is investigated numerically and experimentally. The 3D thermo-elasto-gasdynamic bearing model comprises the description of bump and top foil deflection and the calculation of the pressure and temperature distribution in the air film as well as the temperature distributions in the surrounding structure, namely in the rotor, in the bearing sleeve and in the top and bump foil. Temperature distributions in the air film and in the surrounding structure are obtained from the 3D energy equation and appropriate heat equations. To reduce the computational effort for the solution of the governing system of nonlinear integro-partial differential equations, different approaches for a mathematical reduction of the 3D energy equation and the generalized Reynolds equation are applied and compared with respect to computation time and accuracy. The governing equations are solved by the finite element method. In order to validate the numerical results, different experiments are accomplished on two different test rigs. Using the first test rig - the hysteresis device - hysteresis curves of differently preloaded three-pad air foil journal bearings are measured at zero running speed. The numerical model of the elastic foil structure is validated by a comparison between measured and predicted hysteresis curves, foil structural stiffness and frictional loss (damping). On a second test rig - the automated high-speed test rig - the effect of the assembly preload on the drag torque and on the thermal behavior of three-pad air foil journal bearings is investigated experimentally. For the purpose of validating the thermal model of the preloaded three-pad air foil journal bearing, measured and predicted bearing temperatures are compared.
