Subjects: subject: Museumsarchitektur
subject: Museum architecture

description: Die Diplomarbeit beschäftigt sich mit dem Entwurf eines Ausstellungsortes im Herzen der Stadt Innsbruck. Das Museum hat den Namen Kunst[szene] und bildet eine Schnittstelle zwischen Kunst, Architektur, Technologie und Gesellschaft. Zu den wichtigen Entwurfsparametern zählen vor allem die Sichtachsen. Die Sichtbeziehungen zwischen dem Marktplatz und der gegenüberliegenden Innseite (Mariahilfzeile) sind unter anderem ausschlaggebend für die Form des Gebäudes. Diese passt sich den Sichtachsen an und ermöglicht Blickbezüge in verschiedene Richtungen. Ein weiterer wichtiger Punkt ist der Zugang zum Inn. Hier wird eine Verbindung zwischen dem Marktplatz und dem Fluss hergestellt, um einen Mehrwert für den Platz zu schaffen. Die Verbindung zum Inn, welches als Sitzlandschaft und als Zugang zum Wasser dient, orientiert sich in Richtung Nordkette. Der Schwerpunkt des Entwurfes liegt nicht nur auf der rein ausgestellten Kunst bzw. dem „Endprodukt“, sondern vielmehr auf dem Entstehungsprozess eines Kunstwerkes. Der Besucher hat neben den Ausstellungen auch die Möglichkeit durch interaktive Installationen den Prozess selber zu erleben und zu verstehen. Dabei wird nach dem Motto „Do it yourself“ Wissen vermittelt und das Interesse des Besuchers erweckt. Die Kunst[szene] versteht sich als ein Forum für die Auseinandersetzung mit unterschiedlichen Sichtweisen und fungiert als ein Ort der Begegnungen und des Austausches.
description: The diploma thesis deals with the design of an exhibition venue in the heart of the city of Innsbruck. The museum has the name Kunst[szene] and forms an interface between art, architecture, technology and society. The most important design parameters are above all the visual axes. The visual relations between the marketplace and the opposite side (Mariahilfzeile) are among other things crucial for the shape of the building. Furthermore the adjustment of the shape allows visitors to experience visual references in different directions. Another important point is the access to the river “Inn”. In order to create an added value for the building site, a connection between the market place and the river “Inn” is being made through an acces point, which serves as a seating public area and a portal to the water. This public space is oriented towards the Nordkette. The focus of the design is not only on the purely exhibited art or the “final product”, but rather on the creation process of a work of art. Due to interactive installations the visitor has the opportunity to experience and understand the process himself, in addition to common exibitions. In doing so, knowledge is conveyed according to the motto “Do it yourself” and the interest of the visitor is awakened. The Kunst[szene] sees itself as a forum for dealing with different perspectives and acts as a place for encounters and exchanges.

description: In this paper we present a generalisation of a theorem due to Cornalba and Harris, which is an application of Geometric Invariant Theory to the study of invariants of fibrations. In particular, our generalisation makes it possible to treat the problem of bounding the invariants of general fibred surfaces. As a first application, we give a new proof of the slope inequality and of a bound for the invariants associated to double cover fibrations.

description: A study of 50 supergranular cells obtained from SOHO Dopplergrams was undertaken in order to investigate the relationship between the lifetime ($T$) and the horizontal flow velocity ($v_h$) of the cells. For this sample we find that the two parameters are correlated with a relation $v_h\propto T^{0.5}$ and $T$ is identified with the eddy turn-over time. This is in agreement with the turbulent convective model of the solar atmosphere where the velocity spectrum of supergranular field given by '$v_h \propto L^{1/3}$' can be identified with the Kolmogorov spectrum for the eddy size $L$.

description: This article investigates a cross-modal retrieval problem in which a user would like to retrieve a passage of music from a MIDI file by taking a cell phone picture of several lines of sheet music. This problem is challenging for two reasons: it has a significant runtime constraint since it is a user-facing application, and there is very little relevant training data containing cell phone images of sheet music. To solve this problem, we introduce a novel feature representation called a bootleg score which encodes the position of noteheads relative to staff lines in sheet music. The MIDI representation can be converted into a bootleg score using deterministic rules of Western musical notation, and the sheet music image can be converted into a bootleg score using classical computer vision techniques for detecting simple geometrical shapes. Once the MIDI and cell phone image have been converted into bootleg scores, we can estimate the alignment using dynamic programming. The most notable characteristic of our system is that it has no trainable weights at all -- only a set of about 40 hyperparameters. With a training set of just 400 images, we show that our system generalizes well to a much larger set of 1600 test images from 160 unseen musical scores. Our system achieves a test F measure score of 0.89, has an average runtime of 0.90 seconds, and outperforms baseline systems based on music object detection and sheet-audio alignment. We provide extensive experimental validation and analysis of our system.

Evidence for X-ray Obscuration in Type II Quasar Candidates from the Sloan Digital Sky Survey

description: Recently, Zakamska et al. (2003) selected 291 high-ionization narrow emission-line AGN in the redshift range 0.3-0.83 from the Sloan Digital Sky Survey spectroscopic data. The sample includes both Seyfert II galaxies and their higher luminosity "cousins", Type II quasar candidates. Here we present the results on the X-ray properties of 17 of these objects for which archival X-ray data (ROSAT and XMM-Newton) are available. Three sources have been significantly (>6 sigma) detected, one being the most radio-loud source of the sample; its X-ray emission, possibly enhanced by jet emission, is consistent with the absence of absorption. Another source has a ~6 sigma detection in the ROSAT All-Sky Survey, possibly complex radio structure, and no evidence for strong X-ray absorption. For the third X-ray detection, the XMM-Newton spectrum indicates a column density of NH=1.26+0.75/-0.51x10^22 cm^-2; this result, coupled with the 2-10 keV luminosity of ~4x10^44 cgs, makes this source a genuine Type II quasar. Using the O[III]5007 line luminosities, we estimated the intrinsic X-ray power of the AGN and found that >47% of the observed sample shows indications of X-ray absorption, with column densities >10^22 cm^-2. This provides further evidence that a considerable fraction are obscured quasars. Support to our conclusions also comes from the recent analysis of RASS data performed by Zakamska et al. (2004), who found five additional lower significance (~2.1-3.6 sigma) X-ray matches.

On the Dynamical Origins of Retrograde Jupiter Trojans and their Connection to High-Inclination TNOs
Creators: name: Köhne, Tobias

Publisher: name: arXiv
Year: 2020
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Over the course of the last decade, observations of highly-inclined (orbital inclination i > 60°) Trans-Neptunian Objects (TNOs) have posed an important challenge to current models of solar system formation (Levison et al. 2008; Nesvorný 2015). These remarkable minor planets necessitate the presence of a distant reservoir of strongly-out-of-plane TNOs, which itself requires some dynamical production mechanism (Gladman et al. 2009; Gomes et al. 2015; Batygin and Brown 2016). A notable recent addition to the census of high-i minor bodies in the solar system is the retrograde asteroid 514107 Ka'epaoka'awela, which currently occupies a 1:-1 mean motion resonance with Jupiter at i = 163° (Wiegert et al. 2017). In this work, we delineate a direct connection between retrograde Jupiter Trojans and high-i Centaurs. First, we back-propagate a large sample of clones of Ka'epaoka'awela for 100 Ma numerically, and demonstrate that long-term stable clones tend to decrease their inclination steadily until it concentrates between 90° and 135°, while their eccentricity and semi-major axis increase, placing many of them firmly into the trans-Neptunian domain. Importantly, the clones show significant overlap with the synthetic high-i Centaurs generated in Planet 9 studies (Batygin et al. 2019), and hint at the existence of a relatively prominent, steady-state population of minor bodies occupying polar trans-Saturnian orbits. Second, through direct numerical forward-modeling, we delineate the dynamical pathway through which conventional members of the Kuiper Belt's scattered disk population can become retrograde Jovian Trojan resonators in presence of Planet 9.

Manchester : a modern morality play in three acts
Creators: name: Smith, Adrienne
Publisher: name: University of British Columbia
Year: 2009

description: This is a play about the city of Manchester in 1842, just a few short months before the Plug Riots, and a few years before an important strike by the region's miners. While it deals with working class political activism, the play is informed by performance theory and is about the performative nature of identity, rather than being strictly an intervention into the 'condition of the working class1 literature. It interrogates, rather than celebrates. The play is prefaced by some programatic programme notes which orient the play in theory. The play is modelled on medieval morality plays and follows the misadventures of a character called Everyman as he is led astray and then finds his way, more or less, back to the "correct" path. It also follows Manchester on the same journey. However the play is a modern morality play, and that means none of the loose threads are tied up at the end. The city of Manchester is more than just a neutral setting where the action unfolds; it is an active staging, which makes possible the various staged performances for the actors, and for ourselves. The play explores issues around the performative, and urges the audience members to move past their experience as spectators and to take the play's radical notion of the performative out of the theatre and into the world.

description: Polydimethylsiloxane (PDMS) is an insulator and it is commonly used in fabrication of micro-structures but there is a need of electrical conductive PDMS. Therefore, this research is mainly focused on producing PDMS nanocomposites with high electrical conductivity. Thus, we produced highly conductive PDMS nanocomposites which were filled with multiwalled carbon nanotubes (MWCNTs) and graphene nanoplatelets (GNPs). Due to the synergistic effect between CNTs and GNPs inside a polymeric matrix, we expected to obtain more conductive nanocomposites than PDMS nanocomposite filled with only CNTs. Additionally, we investigated the effect of sulfuric acid treatment to surface composition and electrical conductivity of prepared PDMS/MWCNT/GNP nanocomposites. Results indicated that electrical conductivity of sulfuric acid-treated samples was significantly higher than untreated samples. The level of conductivity in the range of from 270.7 to 1074.9 S/m was obtained, and the higher ones are the samples treated with acid solution.

description: On every compact, orientable, irreducible 3-manifold V which is toroidal or has torus boundary components we construct a contact 1-form whose Reeb vector field R does not have any contractible periodic orbits and is tangent to the boundary. Moreover, if bdry V is nonempty, then the Reeb vector field R is transverse to a taut foliation. By appealing to results of Hofer, Wysocki, and Zehnder, we show that, under certain conditions, the 3-manifold obtained by Dehn filling along bdry V is irreducible and different from the 3-sphere. Resumé On construit, sur toute variete V de dimension trois orientable, compacte, irreductible, bordee par des tores ou toroidale, une forme de contact dont le champ de Reeb R est sans orbite periodique contractible et tangent au bord. De plus, si le bord de V est non vide, le champ R est transversal a un feuilletage tendu. En utilisant des resultats de Hofer, Wysocki et Zehnder, on obtient sous certaines conditions que la variete obtenue par obturation de Dehn le long du bord de V est irreductible et differente de la sphere S^3.

title: Backscatter statistical analysis using multi-temporal sentinel-1 SAR data for land cover mapping in Europe
Creators: name: Bojor, Alexandra-Ioana
Publisher: name: TU Wien
Year: 2019
Subjects: subject: Remote sensing

description: The aim of this study is to demonstrate the potential of using Sentinel-1 SAR data for mapping land cover using CORINE Land Cover nomenclature and Google Earth Engine, based on the analysis of the temporal variation of the backscatter. To this aim dualand singlepolarization, interferometric Wide swath mode (IW) for year 2016 over five different test sites in Europe was used. Backscatter temporal variation for different statistic parameters and for different combination of VV and VH polarization was analyzed for a better understanding of its signature for different land cover classes and for obtaining a good classification of the data. In addition, the statistical class separability for different class pairs and the NDVI for each test area were analyzed. Support Vector Machine (SVM) method was used to classify the dataset. During the classification, different scenarios were used to find out which combination would give a good classification with a high accuracy. The different combinations of VV and VH polarizations were used in conjunction with other data, like DEM, aspect and local incidence angle to obtain a high accuracy. The resulting classified images have been assed using the overall accuracy and the Kappa coefficient. Results demonstrated that while using only the mean single polarization, the classification accuracy would be low, but by using a combination of dual polarization in conjunction with ancillary data, the accuracy would increase, namely the overall accuracy increases up to 90.82% and Kappa coefficient up to 0.85. Thus, the information on the temporal variation of the backscatter can be used successfully for mapping different land cover types.

description: We investigate the total variance of a quantum state with respect to a complete set of mutually complementary measurements and its relation to the Brukner-Zeilinger invariant information. By summing the variances over any complete set of mutually unbiased measurements and general symmetric informationally complete measurements respectively, we show that the Brukner-Zeilinger invariant information associated with such types of quantum measurements is equal to the difference between the maximal variance and the total variance obtained. These results provide an operational link between the previous interpretations of the Brukner-Zeilinger invariant information.

Constraints on the Primordial Power Spectrum from High Resolution Lyman-alpha Forest Spectra and WMAP

Publisher: name: arXiv

description: The combined analysis of the cosmic microwave background on large scales and Lyman-alpha forest on small scales provides a sufficiently long lever arm to obtain strong constraints on the slope and curvature of the power spectrum of primordial density fluctuations. We present results from the combination of the first year WMAP data and the dark matter power spectrum inferred by Viel et al. (2004) for two different sets of high resolution and high signal-to-noise quasar absorption spectra: the Croft et al. (2002) sample with a median redshift z=2.72 and the LUQAS sample (Kim et al. 2004) with a median redshift z=2.125. The best fit value for the {\it rms} fluctuation amplitude of matter fluctuations is sigma_8 =0.94 +- 0.08 and n=0.99 +- 0.03, if we do not include running of the spectral index. The best fit model with a running spectral index has parameters n=0.959 +- 0.036 and n_run=-0.033 +- 0.025. The data is thus consistent with a scale-free primordial power spectrum with no running of the spectral index. We further include tensor modes and constrain the slow-roll parameters of inflation.

String Matching and 1d Lattice Gases
Creators: name: Mungan, Muhittin
Publisher: name: arXiv
Year: 2004
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We calculate the probability distributions for the number of occurrences $n$ of a given $l$ letter word in a random string of $k$ letters. Analytical expressions for the distribution are known for the asymptotic regimes (i) $k \gg r^l \gg 1$ (Gaussian) and $k,l \to \infty$ such that $k/r^l$ is finite (Compound Poisson). However, it is known that these distributions do now work well in the intermediate regime $k \gtrsim r^l \gtrsim 1$. We show that the problem of calculating the string matching probability can be cast into a determining the configurational partition function of a 1d lattice gas with interacting particles so that the matching probability becomes the grand-partition sum of the lattice gas, with the number of particles corresponding to the number of matches. We perform a virial expansion of the effective equation of state and obtain the probability distribution. Our result reproduces the behavior of the distribution in all regimes. We are also able to show analytically how the limiting distributions arise. Our analysis builds on the fact that the effective interactions between the particles consist of a relatively strong core of size $l$, the word length, followed by a weak, exponentially decaying tail. We find that the asymptotic regimes correspond to the case where the tail of the interactions can be neglected, while in the intermediate regime they need to be kept in the analysis. Our results are readily generalized to the case where the random strings are generated by more complicated stochastic processes such as a non-uniform letter probability distribution or Markov chains. We show that in these cases the tails of the effective interactions can be made even more dominant rendering thus the asymptotic approximations less accurate in such a regime.
description: 44 pages and 8 figures. Major revision of previous version. The lattice gas analogy has been worked out in full, including virial expansion and equation of state. This constitutes the main part of the paper now. Connections with existing work is made and references should be up to date now. To be submitted for publication
Magnetism and stability of all primitive stacking patterns in bilayer chromium trihalides

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Chromium trihalides, CrX$_3$ (with X = Cl, Br, I), are a family of layered magnetic materials that can be easily exfoliated to provide ferromagnetic monolayers. When two layers are stacked together to form a bilayer the interlayer exchange coupling can be either ferromagnetic or antiferromagnetic depending on the stacking sequence. Here we combine crystallographic arguments based on the close-packing condition with first-principles simulations to enumerate all possible stacking patterns in CrX$_3$ bilayers that preserve the spatial periodicity of each layer. We recover all configurations observed in bulk crystals and disclose stacking sequences with no bulk counterpart where the two layers have opposite chirality. Stacking sequences are ranked according to their relative stability and a preferential interlayer magnetic ordering is assigned to each of them. Simulations provide a consistent picture to frame all current experimental observations on bulk and exfoliated CrX$_3$ crystals, with interesting implications for future measurements, including synthetic bilayers with non-standard stacking patterns.

description: Supermarkets and hypermarkets are expanding rapidly in many developing countries. While consequences for farmers and consumers were analyzed recently, little is known about the implications for traditional retail formats such as wet markets. Using data from a market survey in Thailand and hedonic regression models, we analyze quality and prices for fresh vegetables from different retail outlets. Compared to wet markets, modern retailers sell higher quality at higher prices, indicating that they are primarily targeting better-off consumers. Hence, they are not directly competing for the same market segments. Yet there are signs that modern and traditional markets will gradually converge.

Connecting the free parameters of the models with the cosmic matter and vacuum energy density parameters, it is shown that the models are equivalent. Using the selected models, the present values of some of the physical parameters have been estimated, and a glimpse at the past decelerating universe has also been presented. It is observed that most of these cosmological parameters nicely agree with the values suggested by the Type Ia Supernovae and other experimental data.

description: Cette étude analyse en profondeur le budget 2024 du Mali, confronté à des défis sécuritaires et des besoins en développement, en se focalisant sur la capacité de ce budget à rationaliser les dépenses de l'État et à équilibrer les dépenses de sécurité avec les investissements en développement socio-économique. Couvrant 2019-2024, elle utilise des méthodes quantitatives et qualitatives, dont des régressions linéaires et des entretiens avec 24 officiers militaires. L'analyse révèle une augmentation des dépenses de défense et de sécurité, sans amélioration proportionnelle des indicateurs de sécurité. Une corrélation modérée, mais statistiquement non significative, est observée entre les dépenses sécuritaires et les taux de mortalité liés aux conflits. Les entretiens mettent en évidence la perception d'un besoin accru en dépenses de sécurité, malgré une efficacité à long terme incertaine. L'étude souligne ainsi l'importance d'une gestion budgétaire équilibrée, intégrant les dépenses de sécurité et les investissements en développement socio-économique, pour favoriser une croissance et une stabilité durables au Mali.

description: Recently the Master Constraint Programme for Loop Quantum Gravity (LQG) was proposed as a classically equivalent way to impose the infinite number of Wheeler -- DeWitt constraint equations in terms of a single Master Equation. While the proposal has some promising abstract features, it was until now barely tested in known models. In this series of five papers we fill this gap, thereby adding confidence to the proposal. We consider a wide range of models with increasingly more complicated constraint algebras, beginning with a finite dimensional, Abelean algebra of constraint operators which are linear in the momenta and ending with an infinite dimensional, non-Abelean algebra of constraint operators which closes with structure functions only and which are not even polynomial in the momenta. In all these models we apply the Master Constraint Programme successfully, however, the full flexibility of the method must be exploited in order to complete our task. This shows that the Master Constraint Programme has a wide range of applicability but that there are many, physically interesting subtleties that must be taken care of in doing so. In this first paper we prepare the analysis of our test models by outlining the general framework of the Master Constraint Programme. The models themselves will be studied in the remaining four papers. As a side result we develop the Direct Integral Decomposition (DID) for solving quantum constraints as an alternative to Refined Algebraic Quantization (RAQ).

Heuristic cues automatically activate disease cognitions despite rational knowledge to the contrary
Creators: name: Duncan, Lesley Alexandra
Publisher: name: University of British Columbia
Year: 2009

description: According to one adaptive perspective on social cognition, the perception of facial disfigurement activates an evolved disease-avoidance mechanism, and in so doing automatically triggers disease-relevant cognitions. The present study used the implicit association test (IAT; Greenwald, McGhee & Schwartz, 1998), a computer-based reaction-time methodology to provide an especially strong test of the alleged automaticity of this disfigurement-disease linkage. The methods were designed to measure who is more likely to be implicitly linked to the concept "disease"- (a) a person who is known to be healthy but who has a facial disfigurement, or (b) a person who is known to be infected with a contagious disease but who looks just fine. The findings suggest that the tendency to associate disfigurement with disease is automatic and can actually override explicit rational knowledge to the contrary. Some limitations and implications of the study are discussed.

description: The chemical composition of high redshift galaxies is an important property which gives clues to their past history and future evolution and yet is difficult to measure with current techniques. In this paper we investigate new metallicity indicators, based upon the strengths of stellar photospheric features at rest-frame ultraviolet wavelengths. By combining the evolutionary spectral synthesis code Starburst99 with the output from the non-LTE model atmosphere code WM-basic, we have developed a code that can model the integrated ultraviolet stellar spectra of star-forming regions at metallicities between 1/20 and twice solar. We use our models to explore a number of spectral regions that are sensitive to metallicity and clean of other spectral features. The most promising metallicity indicator is an absorption feature between 1935 A and 2020 A, which arises from the blending of numerous Fe III transitions. We compare our model spectra to observations of two well studied high redshift star-forming galaxies, MS1512-cB58 (a Lyman break galaxy at z = 2.7276), and Q1307-BM1163 (a UV-bright galaxy at z = 1.411). The profiles of the photospheric absorption features observed in these galaxies are well reproduced by the models. In addition, the metallicities inferred from their equivalent widths are in good agreement with previous determinations based on interstellar absorption and nebular emission lines. Our new technique appears to be a promising alternative, or complement, to established methods which have only a limited applicability at high redshifts.

description: We calibrate reverberation-based black hole masses in active galactic nuclei (AGNs) by using the correlation between black hole mass, M, and bulge/spheroid stellar velocity dispersion, sigma. We use new measurements of sigma for 6 AGNs and published velocity dispersions for 10 others, in conjunction with improved reverberation mapping results, to determine the scaling factor required to bring reverberation-based black hole masses into agreement with the quiescent galaxy M-sigma relationship. The scatter in the AGN black hole masses is found to be less than a factor of 3. The current observational uncertainties preclude use of the scaling factor to discriminate between broad-line region models.

description: This is the third paper in our series of five in which we test the Master Constraint Programme for solving the Hamiltonian constraint in Loop Quantum Gravity. In this work we analyze models which, despite the fact that the phase space is finite dimensional, are much more complicated than in the second paper: These are systems with an $SL(2,\Rl)$ gauge symmetry and the complications arise because non -- compact semisimple Lie groups are not amenable (have no finite translation invariant measure). This leads to severe obstacles in the refined algebraic quantization programme (group averaging) and we see a trace of that in the fact that the spectrum of the Master Constraint does not contain the point zero. However, the minimum of the spectrum is of order $\hbar^2$ which can be interpreted as a normal ordering constant arising from first class constraints (while second class systems lead to $\hbar$ normal ordering constants). The physical Hilbert space can then be be obtained after subtracting this normal ordering correction.

description: The present work is devoted to massive gauge fields in special relativity with two fundamental constants-the velocity of light, and the Planck length, so called doubly special relativity (DSR). The two invariant scales are accounted for by properly modified boost parameters. Within above framework we construct the vector potential as the (1/2,0)x(0,1/2) direct product, build the associated field strength tensor together with the Dirac spinors and use them to calculate various observables as functions of the Planck length.

Path Integration on Darboux Spaces

Publisher: name: arXiv
Year: 2004
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In this paper the Feynman path integral technique is applied to two-dimensional spaces of non-constant curvature: these spaces are called Darboux spaces $\DI$--$\DIV$. We start each consideration in terms of the metric and then analyze the quantum theory in the separable coordinate systems. The path integral in each case is formulated and then solved in the majority of cases, the exceptions being quartic oscillators where no closed solution is known. The required ingredients are the path integral solutions of the linear potential, the harmonic oscillator, the radial harmonic oscillator, the modified Pöschl--Teller potential, and for spheroidal wave-functions, respectively. The basic path integral solutions, which appear here in a complicated way, have been developed in recent work and are known. The final solutions are represented in terms of the corresponding Green's functions and the expansions into the wave-functions, respectively. We also sketch some limiting cases of the Darboux spaces, where spaces of constant negative and zero curvature emerge.

Efficient Trace Encodings of Bounded Synthesis for Asynchronous Distributed Systems

description: The manual implementation of distributed systems is an error-prone task because of the asynchronous interplay of components and the environment. Bounded synthesis automatically generates an implementation for the specification of the distributed system if one exists. So far, bounded synthesis for distributed systems does not utilize their asynchronous nature. Instead, concurrent behavior of components is encoded by all interleavings and only then checked against the specification. We close this gap by identifying true concurrency in synthesis of asynchronous distributed systems represented as Petri games. This defines when several interleavings can be subsumed by one true concurrent trace. Thereby, fewer and shorter verification problems have to be solved in each iteration of the bounded synthesis algorithm. For Petri games, experimental results show that our implementation using true concurrency outperforms the implementation based on checking all interleavings.
