description: Die bekannten Verfahren zur Berechnung der Auftriebsverteilung von Tragflügeln endlicher Spannweite im unbegrenzten Raum werden auf Tragflügel in Bodennähe erweitert. Dabei wird der Bodeneinfluß durch das Spiegelungsprinzip erfaßt. Die bisher in der Tragflügeltheorie benutzten Wirbelmodelle erfordern die Beschränkung auf kleine Anstellwinkel (lineare Theorie). Bei Annäherung an den Boden nimmt der Auftrieb sowohl bei festem Anstellwinkel als auch bei festem Klappenwinkel zu, der induzierte Widerstand bei festem Auftrieb nimmt dagegen ab. Der aerodynamische Neutralpunkt rückt nach hinten (stabilisierend). An Hand von Beispielrechnungen wird der Einfluß von Bodenabstand, Seitenverhältnis und Pfeilung auf den Bodeneffekt ermittelt.
description: The well-known methods for calculating the lift distribution on wings of finite aspect ratio in an unbounded flow field are extended for wings near the ground. The ground effect is taken into account by the reflection method. The vortex models used till now in the wing theories require a restriction to small angles of attack (linear theory). Approaching to the ground the lift increases for a constant angle of attack as well as for a constant flap angle, the induced drag, however, decreases at constant lift. The aerodynamic centre is displaced backwards (stabilizing). By means of calculated examples the dependence of the ground effect on the height above ground, the aspect ratio and the angle of sweep is determined.

Type species
Luperodes spretus Horn, 1893, by present designation.
Diagnosis
The antennae of this genus are unusual among the Scelidites, the third antennomere being fully twice as long as the second. See the following key for additional diagnostic characters.
Etymology
The name ‘ Texiluperus ’ suggests that the genus occurs in Texas, which is the case for both described species. The name should be treated as a male noun.
Remarks
This genus includes two putative species, both of which were originally named in Luperodes and most recently placed in Pseudoluperus: T. spretus (Horn, 1893) comb. nov. and T. texanus (Horn, 1893) comb. nov. Future study might show that they are mere color forms of a single variable species. See Wilcox (1965) for a key that includes the two putative species (as part of Pseudoluperus).

description: The diffusion limited aggregation model (DLA) and the more general dielectric breakdown model (DBM) are solved exactly in a two dimensional cylindrical geometry with periodic boundary conditions of width 2. Our approach follows the exact evolution of the growing interface, using the evolution matrix E, which is a temporal transfer matrix. The eigenvector of this matrix with an eigenvalue of one represents the system's steady state. This yields an estimate of the fractal dimension for DLA, which is in good agreement with simulations. The same technique is used to calculate the fractal dimension for various values of eta in the more general DBM model. Our exact results are very close to the approximate results found by the fixed scale transformation approach.

Year: 2024

description: This use case is drafted within the framework of the ASHVIN project, funded by the European Union, to develop a novel system based on digital twin technologies to support the design engineering, construction, and maintenance phases of projects in the construction sector. 

 

This document provides background and describes a use case of applying historic data from past construction operations that were tracked with construction site digital twin technology to support future design activities. The use can proposes to use historic data, identify performance metricsm and then use parametric modeling, generative design, optimization, and pareto-front-based decision-making to support help designers already in early design stages.

 

The ASHVIN system comprises 10 smart building applications, and this use case is related to the GEN tool (full name: Generative design modeller to support design for productivity, resource efficiency and safety). 

The ASHVIN toolkit was demonstrated across 10 European demonstration sites, and this use case is related to the demo site # 8 Footbridge in Germany.

description: We describe a procedure for engineering beams of cold atoms by selectively draining particles from a trapped gas based on momenta. Atoms escape through a filter potential that only transmits atoms with the desired momenta. We outline an algorithm that outputs a filter potential that produces a pre-specified beam momentum profile. We illustrate this procedure for the case of a narrow band-pass (NBP) quantum filter. Lastly, we discuss the application of the NBP filter for probing the self-energy and effective mass of Bose polarons, as well as the corresponding Landau criterion.

description: In this paper we provide a quantitative comparison of two obstructions for a given symmetric operator S with dense domain in Hilbert space ${\cal H}$ to be selfadjoint. The first one is the pair of deficiency spaces of von Neumann, and the second one is of more recent vintage: Let P be a projection in ${\cal H}$. We say that it is smooth relative to S if its range is contained in the domain of S. We say that smooth projections $\{P_i \}_{i=1}^{\infty}$ diagonalize S if (a) $(I-P_{i})SP_i=0$ for all i, and (b) $\sup_{i}P_{i}=I$. If such projections exist, then S has a selfadjoint closure (i.e., $\bar{S}$ has a spectral resolution), and so our second obstruction to selfadjointness is defined from smooth projections $P_i$ with $(I-P_i)SP_i \neq 0$. We prove results both in the case of a single operator S and a system of operators.

description: ABSTRACTObjective: To determine radiologic dimensions of the eustachian tube of adult Filipinos diagnosed with chronic otitis media with and without cholesteatoma using temporal bone CT scans at the Rizal Medical Center. Methods:Design: Retrospective descriptive studySetting:  Tertiary Government Training HospitalParticipants:  The temporal bone CT scans of 69 patients with chronic otitis media with or without cholesteatoma diagnosed at Rizal Medical Center Department of Otorhinolaryngology-Head and Neck Surgery from January 2020 to January 2023 were reviewed for the measurement of the Eustachian tube dimensions. Results: The average measurements of the pre-tympanic diameter and ET angle (Reid plane) in the group with cholesteatoma were found to be higher than those in the group without cholesteatoma. The pre-tympanic diameter was 4.1993 ± 0.50 compared to 4.002 ± 1.13, and the ET angle was 26.483 ± 3.86 compared to 24.649 ± 3.10. While the mean measurement of the tubotympanic angle in the group without cholesteatoma was greater than that in the group with cholesteatoma, with values of 141.994 ± 6.30 and 138.789 ± 7.13, respectively. The p-values for the pre-tympanic diameter, tubotympanic angle, and ET angle were 0.617, 0.198, and 0.098, respectively, p<0.05 indicating that there was no statistically significant differences in the ET dimensions among the group with cholesteatoma, without cholesteatoma and normal ears. Conclusion: The occurrence of cholesteatoma in individuals with chronic otitis media can be multifactorial. In our investigation, there was no statistical significance in Eustachian tube dimensions among individuals with normal ears and those with and without cholesteatoma. Consequently, these findings imply that Eustachian tube dimensions may not represent a primary etiological factor associated with chronic otitis media in adult Filipino patients.
Beyond the Poles in Attractor Models of Inflation

description: We offer a geometric interpretation of attractor theories with singular kinetic terms as a union of multiple canonical models. We demonstrate that different domains (separated by poles) can drastically differ in their phenomenology. We illustrate this with the help of a "master model" that leads to distinct predictions depending on which side of the pole the field evolves before examining the more realistic example of $α$-attractor models. Such models lead to quintessential inflation within the poles when featuring an exponential potential. However, beyond the poles, we discover a novel behaviour: the scalar field responsible for the early-time acceleration of the Universe may reach the boundary of the field-space manifold, indicating that the theory is incomplete and that a boundary condition must be imposed in order to determine its late-time behaviour. If the evolution of the field is arrested before this happens, however, we discover that quintessence can be achieved without a potential offset. Turning to multifield models with singular kinetic terms, we see that poles generalise straightforwardly to singular curves, which act as "model walls" between distinct pole-free inflationary models. As an example, we study a simple two-field $α$-attractor-inspired model, whose evolution of isocurvature perturbations is sensitive to where the non-canonical field begins its trajectory. We finally discuss initial conditions in attractor theories, where the existence of multiple disconnected canonical models implies that we must make a fundamental choice: in which domain we impose a distribution for the inflaton in order to then determine the likelihood of inflation.

We then study the effect of global monopole charge on particle orbits and the Hawking radiation. It turns out that existence, boundedness and stability of circular orbits scale up by $(1-8 πη^2)^{-1}$, and the perihelion shift and the light bending by $(1-8 πη^2)^{-3/2}$, while the Hawking temperature scales down by $(1 - 8 πη^2)^2$ the Schwarzschild values. Here $η$ is the global charge.

description: Defining the allocation of decision rights for enterprise applications is a crucial issue in IT governance and organization design. Today, emerging delivery models such as Software as a Service (SaaS) defy the notion of the internal IT department as the focal point of centralized governance. Recognizing the importance of this issue, we find that the phenomenon of ‘SaaS governance’ itself is not yet well understood. Based on two cases of SaaS adoption, we take a process-theoretic approach to investigate the complex interaction between factors that influence in the allocation of SaaS authority. The results suggest that some factors, such as the locus of initiative and the decision for SaaS, interact with absorptive capacities and determine the later mode of application governance at a very early stage. Thus, the initiative for introducing SaaS emerges as an important intermediate variable between the overall IT governance mode and the resulting SaaS governance outcome.

description: We study the energy spectrum of a two-dimensional electron in the presence of both a perpendicular magnetic field and a potential. In the limit where the potential is small compared to the Landau level spacing, we show that the broadening of Landau levels is simply expressed in terms of the structure factor of the potential. For potentials that are either periodic or random, we recover known results. Interestingly, for potentials with a dense Fourier spectrum made of Bragg peaks (as found, e.g., in quasicrystals), we find an algebraic broadening with the magnetic field characterized by the hyperuniformity exponent of the potential. Furthermore, if the potential is self-similar such that its structure factor has a discrete scale invariance, the broadening displays log-periodic oscillations together with an algebraic envelope.

After deriving the transition matrix of the system by using the self-adjoint extension theory of functional analysis, we deduce the general condition for the appearance of chaos. The prediction is confirmed by numerically examining the statistical properties of energy spectrum of rectangular billiards with multiple point interactions inside. The dependence of the level statistics on the strength as well as the number of the scatterers is displayed.

description: We study the time evolving currents flowing in an interacting, ring-shaped nanostructure after a bias voltage has been switched on. The source-to-drain current exhibits the expected relaxation towards its quasi-static equilibrium value at a rate $Γ_0$ reflecting the lead-induced broadening of the ring states. In contrast, the current circulating within the ring decays with a different rate $Γ$, which is a rapidly decaying function of the interaction strength and thus can take values orders of magnitude below $Γ_0$. This implies the existence of a regime in which the nanostructure is far from equilibrium even though the transmitted current is already stationary. We discuss experimental setups to observe the long-lived ring transients.

description: Passive water treatment is often sought as a component of long-term mine closure scenarios, as it promotes relatively self-sustaining beneficial conditions for impacted water management at low maintenance and operational costs. However, owing to the biogeochemical nature of these technologies, a site-specific phased approach is necessary for successful implementation. Huckleberry Mine was evaluated for the viability of passive water treatment technologies to address potential future acid rock drainage (ARD)-impacted waters containing constituents such as aluminum and copper. Natural wetlands, seepage collection ponds, and ARD-impacted areas were assessed using genetic microbial community profiling, paired with traditional growth-based microbial characterization and quantification. This information was evaluated in the context of water chemistry, treatment objectives, and biogeochemical processes to develop a conceptual treatment train to semi-passively treat water. A phased program was then developed to determine if each step of the treatment train could address its goals individually, or if it would be best implemented to reduce costs associated with an equivalent active water treatment step.

description: This use case is drafted within the framework of the ASHVIN project, funded by the European Union, to develop a novel system based on digital twin technologies to support the design engineering, construction, and maintenance phases of projects in the construction sector. 

 

The current document presents a comprehensive overview and directions for utilizing the Configuration Management based framework to aid quality control in construction sites to achieve optimized productivity, resource efficiency, safety and reduced costs, which are the key performance indicators of the projects. Configuration Management Use Case (CMT) was deployed on several demonstration projects within Europe for quality control of installed building elements during construction using onsite Digital Twin (DT) data. The use case significantly improved the resource efficiency, productivity, safety and costs at construction sites under study.

 

The ASHVIN system comprises 10 smart building applications, and this use case is related to the CMT tool (full name: A configuration management tool to track as-designed and as-built, as well as to allow for seamless commissioning). 

The ASHVIN toolkit was demonstrated across 10 European demonstration sites, and this use case is related to the demo site#5 Kineum Building in Göteborg, Sweden.

description: Optimal prediction methods compensate for a lack of resolution in the numerical solution of time-dependent differential equations through the use of prior statistical information. We present a new derivation of the basic methodology, show that field-theoretical perturbation theory provides a useful device for dealing with quasi-linear problems, and provide a nonlinear example that illuminates the difference between a pseudo-spectral method and an optimal prediction method with Fourier kernels. Along the way, we explain the differences and similarities between optimal prediction, the representer method in data assimilation, and duality methods for finding weak solutions. We also discuss the conditions under which a simple implementation of the optimal prediction method can be expected to perform well.

description: This teacher research project investigates a high school English teacher’s classrooms that combine outdoor activities in nature with literacy activities, including environmental literature read through a lens of ecocriticism. It seeks to answer the overarching research question: What happens when students read environmental literature and experience outdoor activities in English classes that emphasize critical literacy focusing on environmental justice and ecocriticism? The data sets derive from students’ writing and testimony (from interviews) involving cohorts of between three and six students who participated in classroom research studies in 2011, 2012, and 2018. This teacher research project borrows from grounded theory methodologies in the processes of data collection and analysis. Findings from the data suggest that participants showed an ability to read the word and the world in ways that promoted a critical gaze toward social and environmental injustice. Also, students were able to see “what nobody ever sees” in literature and the natural world. A grounded theory of critical rambling is offered.

description: Zur Klärung der Wärmeübergangsprobleme von Plasmen an gekühlte, feste Wandungen wurden an wassergekühlten Rohren, die sich in Lichtbogenentladungen befanden, kalorimetrische Messungen im Beharrungszustand durchgeführt. Als Lichtbögen wurden sowohl freibrennende als auch wasserstabilisierte Kohlestrombögen benutzt. Die spektroskopisch gemessenen Plasmatemperaturen erreichten Werte bis 13000°K; die an die Oberfläche des Kalorimeterrohres übergehenden Wärmestromdichten lagen zwischen 1x10^6 und 100x10^6 W/m^2.
Wie eine Überschlagsrechnung zeigt, wird bei Wärmestromdichten über 25x10^6 W/m^2 die Existenz einer klassischen Temperaturgrenzschicht fragwürdig, da die Grenzschichtdicke in die Größenordnung der freien Weglänge kommt.
Es wird vorgeschlagen, den Wärmeübergang auf Enthalpiedifferenzen zu beziehen und mit einem Stoffaustauschvorgang zu erklären.
description: In order to solve problems in plasma heat-transfer water-cooled tubes acting as calorimeters were introduced into water-stabilized as well as nonstabilized electric arcs. Maximum plasma temperatures were spectroscopically measured to be 13000°K. Heat-flux-densities proved to be 1x10^6 - 100x10^6 W/m^2 on the surface of the water-cooled tube.
At heat-flux-densities exceeding 25x10^6 W/m^2 the existence of conventional temperature-boundary-layers is open to question because of the boundary-layer thickness decreasing to free path dimensions, as checked by a brief calculation.
We therefore propose to refer heat-transfer to enthalpy differences and to explain it with mass transfer phenomenons.

Planet-planet scattering as the source of the highest eccentricity exoplanets

description: Most giant exoplanets discovered by radial velocity surveys have much higher eccentricities than those in the solar system. The planet--planet scattering mechanism has been shown to match the broad eccentricity distribution, but the highest-eccentricity planets are often attributed to Kozai-Lidov oscillations induced by a stellar companion. Here we investigate whether the highly eccentric exoplanet population can be produced entirely by scattering. We ran 500 N-body simulations of closely packed giant-planet systems that became unstable under their own mutual perturbations. We find that the surviving bound planets can have eccentricities up to $e > 0.99$, with a maximum of 0.999017 in our simulations. This suggests that there is no maximum eccentricity that can be produced by planet--planet scattering. Importantly, we find that extreme eccentricities are not extremely rare; the eccentricity distribution for all giant exoplanets with $e > 0.3$ is consistent with all planets concerned being generated by scattering. Our results show that the discovery of planets with extremely high eccentricities does not necessarily signal the action of the Kozai-Lidov mechanism.

description: A density functional theory (DFT) of lattice fermion models is presented, which uses the single-particle density matrix gamma_{ij} as basic variable. A simple, explicit approximation to the interaction-energy functional W[gamma] of the Hubbard model is derived from exact dimer results, scaling properties of W[gamma] and known limits. Systematic tests on the one-dimensional chain show a remarkable agreement with theBethe-Ansatz exact solution for all interaction regimes and band fillings. New results are obtained for the ground-state energyand charge-excitation gap in two dimensions. A successful description of strong electron correlations within DFT is achieved.

The Viscous Nonlinear Dynamics of Twist and Writhe

description: Exploiting the "natural" frame of space curves, we formulate an intrinsic dynamics of twisted elastic filaments in viscous fluids. A pair of coupled nonlinear equations describing the temporal evolution of the filament's complex curvature and twist density embodies the dynamic interplay of twist and writhe. These are used to illustrate a novel nonlinear phenomenon: ``geometric untwisting" of open filaments, whereby twisting strains relax through a transient writhing instability without performing axial rotation. This may explain certain experimentally observed motions of fibers of the bacterium B. subtilis [N.H. Mendelson, et al., J. Bacteriol. 177, 7060 (1995)].

Loop Corrections in the Spectrum of 2D Hawking Radiation

description: We determine the one-loop and the two-loop back-reaction corrections in the spectrum of the Hawking radiation for the CGHS model of 2d dilaton gravity by evaluating the Bogoliubov coefficients for a massless scalar field propagating on the corresponding backgrounds. Since the back-reaction can induce a small shift in the position of the classical horizon, we find that a positive shift leads to a non-Planckian late-time spectrum, while a null or a negative shift leads to a Planckian late-time spectrum in the leading-order stationary-point approximation. In the one-loop case there are no corrections to the classical Hawking temperature, while in the two-loop case the temperature is three times greater than the classical value. We argue that these results are consistent with the behaviour of the Hawking flux obtained from the operator quantization only for the times which are not too late, in accordance with the limits of validity of the semiclassical approximation.

description: For many organizations it is difficult to determine the total costs caused by offering own services in the cloud as well as to compare them with the costs caused by an in-house datacenter. In practice, some models exist that support organizations in analyzing costs. However, these models are mostly static and do not consider the dynamics of cost development when using cloud computing. The purpose of this paper is to design and develop a simulation model that covers such dynamic aspects and supports decision makers in analyzing cost-benefits of cloud computing versus own datacenter. The model is based on a theoretical framework for IS and applies the method of system dynamics.

Guidance for reclamation planning to achieve multiple end land uses

description: In the Athabasca oil sands region, large open-pit mining operations require reclamation to restore the landscape. Oil sand mine operators responsible for reclamation use a revegetation guidance manual, Guidelines for Reclamation to Forest Vegetation in the Athabasca Oil Sands Region, 2nd Edition (the revegetation manual) (Alberta Environment 2010), which is a guidance document that is both a technical document and a planning tool. Operators use the revegetation manual in the development of revegetation plans for reclamation of terrestrial ecosystems, and are required to use the revegetation manual under their Environmental Protection and Enhancement Act (EPEA) approvals. Associated Environmental Consultants along with Integral Ecology Group worked with the Terrestrial Subgroup (TSG) of the Cumulative Environmental Management Association (CEMA) to revise the revegetation manual in preparation for its third update in 2017. Our input focussed on techniques to establish upland forest ecosystems to support multiple end land uses, specifically commercial forestry, wildlife habitat, aboriginal traditional use, and recreation. The approach to changes to the guidance document involved multi-stakeholder collaboration and in the end it provided guidance on working with indigenous communities in reclamation planning. Recommended changes to the manual include: 1) alternative decision-flow charts to guide reclamation planning, and 2) detailed checklists to provide guidance and a way of tracking reclamation inputs towards specific end land uses.
