Experiences from Large-Scale Model Checking: Verifying a Vehicle Control System with NuSMV
Creators: name: Fritzsch, Jonas

Publisher: name: Zenodo
Year: 2021

description: In the age of autonomously driving vehicles, functionality and complexity of embedded systems are increasing tremendously. Safety aspects become more important and require such systems to operate with the highest possible level of fault tolerance. Simulation and systematic testing techniques often reach their limits in this regard. Here, formal verification as a long established technique can be an appropriate complement. However, the necessary preparatory work like adequately modeling a system and specifying properties in temporal logic are anything but trivial. In this paper, we report on our experiences applying model checking to verify the arbitration logic of a Vehicle Control System. We balance pros and cons of different model checking techniques and tools, and reason about our choice of the symbolic model checker NuSMV. We describe the process of modeling the architecture, resulting in ~1500 LOC, 69 state variables and 38 LTL constraints. To handle this large-scale model, we automate and optimize the model checking procedure for use on multi-core CPUs and employ Bounded Model Checking to avoid the state explosion problem. We share our lessons learned and provide valuable insights for architects, developers, and test engineers involved in this highly present topic.

Fermi and Bose pressures in statistical mechanics

description: I show how the Fermi and Bose pressures in quantum systems, identified in standard discussions through the use of thermodynamic analogies, can be derived directly in terms of the flow of momentum across a surface by using the quantum mechanical stress tensor. In this approach, analogous to classical kinetic theory, pressure is naturally defined locally, a point which is obvious in terms of the stress-tensor but is hidden in the usual thermodynamic approach. The two approaches are connected by an interesting application of boundary perturbation theory for quantum systems. The treatment leads to a simple interpretation of the pressure in Fermi and Bose systems in terms of the momentum flow encoded in the wave functions. I apply the methods to several problems, investigating the properties of quasi continuous systems, relations for Fermi and Bose pressures, shape-dependent effects and anisotropies, and the treatment of particles in external fields, and note several interesting problems for graduate courses in statistical mechanics that arise naturally in the context of these examples.

Physics of Tidal Dissipation in Early-Type Stars and White Dwarfs: Hydrodynamical Simulations of Internal Gravity Wave Breaking in Stellar Envelopes

description: In binaries composed of either early-type stars or white dwarfs, the dominant tidal process involves the excitation of internal gravity waves (IGWs), which propagate towards the stellar surface, and their dissipation via nonlinear wave breaking. We perform 2D hydrodynamical simulations of this wave breaking process in a stratified, isothermal atmosphere. We find that, after an initial transient phase, the dissipation of the IGWs naturally generates a sharp critical layer, separating the lower stationary region (with no mean flow) and the upper "synchronized" region (with the mean flow velocity equal to the horizontal wave phase speed). While the critical layer is steepened by absorption of these waves, it is simultaneously broadened by Kelvin-Helmholtz instabilities such that, in steady state, the critical layer width is determined by the Richardson criterion. We study the absorption and reflection of incident waves off the critical layer and provide analytical formulae describing its long-term evolution. The result of this study is important for characterizing the evolution of tidally heated white dwarfs and other binary stars.

description: We argue that the starting point of Kaluza's idea of unifying electrodynamics and gravity was the analogy between gravitation and electromagnetism which was pointed out by Einstein and Thirring. It seems that Kaluza's attention was turned to this point by the three papers on the Lense-Thirring effect and the analogy between gravitation and electromagnetism which were published a short time before Kaluza's paper was submitted. We provide here an English translation of the third of these papers.
An environment for benchmarking combinatorialtest suite generators
Creators: name: Bombarda, Andrea
name: Crippa, Edoardo
name: Gargantini, Angelo
Publisher: name: Zenodo
Year: 2021

description: New tools for combinatorial test generation are proposed every year. However, different generators may have different performances on different models, in terms of the number of tests produced and generation time, so the choice of which generator has to be used can be challenging. Classical comparison between CIT generators considers only the number of tests composing the test suite. Still, especially when the time dedicated to testing activity is limited, generation time can be determinant. Thus, we propose a benchmarking framework including 1) a set of generic benchmark models, 2) an interface to easily integrate new generators, 3) methods to benchmark each generator against the others and to check validity and completeness. We have tested the proposed environment using five different generators (ACTS, CAgen, CASA, Medici, and PICT), comparing the obtained results in terms of the number of test cases and generation times, errors, completeness, and validity. Finally, we propose a CIT competition, between combinatorial generators, based on our framework.

description: We examine how the introduction of self-control preferences influences the trade-off between two fundamental components of a public pension system: the contribution rate and its degree of redistribution. The pension regime affects individuals' welfare by altering how yielding to temptation (i.e. not saving, or saving less) is attractive. We show that proportional taxation increases the cost of self-control, and that this adverse effect is more acute when public pensions become more redistributive.
Representation of human rights and environmental issues in American and Norwegian high school curricula and textbooks -- A comparative study

description: This thesis analyzes how human rights and environmental issues are framed and presented in American and Norwegian high school curricula and textbooks. Based on a mixed methods content analysis the findings suggest that there are significant differences in how the two countries frame, contextualize and present the issues. The Norwegian texts focus on the UN, multilateral cooperation, and international treaties, and emphasize the universality and inherent value of human rights. The American texts present rights mainly in an American context and human rights as an instrument the U.S. can use to protect their national interest. These results concur with the official policy of the two countries as presented by the U.S. Department of State and the Norwegian Ministry of Foreign Affairs. I thus argue that the educational sectors in the two countries contribute to a process of reproducing and reinforcing the agreed consensus in society.
On the galactic chemical evolution of sulfur

Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Sulfur abundances have been determined for ten stars to resolve a debate in the literature on the Galactic chemical evolution of sulfur in the halo phase of the Milky Way. Our analysis is based on observations of the S I lines at 9212.9, 9228.1, and 9237.5 A for stars for which the S abundance was obtained previously from much weaker S I lines at 8694.0 and 8694.6 A. In contrast to the previous results showing [S/Fe] to rise steadily with decreasing [Fe/H], our results show that [S/Fe] is approximately constant for metal-poor stars ([Fe/H] < -1) at [S/Fe] = +0.3. Thus, sulfur behaves in a similar way to the other alpha elements, with an approximately constant [S/Fe] for metallicities lower than [Fe/H] = -1. We suggest that the reason for the earlier claims of a rise of [S/Fe] is partly due to the use of the weak S I 8694.0 and 8694.6 A lines and partly uncertainties in the determination of the metallicity when using Fe I lines. The S I 9212.9, 9228.1, and 9237.5 A lines are preferred for an abundance analysis of sulfur for metal-poor stars.

description: In the young democracy of Iraq, many of the critical questions of governance and political accommodation evident upon the overthrow of the Baathist regime remain unanswered. Powerful political parties advocated for, and implemented, a federalist system for Iraq upon the ratification of the permanent constitution. However, significant questions about the nature and degree of decentralization are as of yet unresolved. This paper will examine the efforts of the parties pushing for a specific version of federalism, referred to as regionalism, and explain their surprising failure to see their vision become reality. This paper will utilize social movement theory to reveal the contrast between the messages used by the regionalist parties and the changing political opportunities available in Iraq. It will find that in the five periods of post-Saddam Iraq, two significant structural shifts undermined the framing efforts of the regionalist parties and created opportunities they were unable to capitalize on.

description: Can central counterparty (CCP) clearing control counterparty risk in the presence of risk taking that can aggravate such risk? When counterparty risk is not observable, I show that central clearing leads to higher collateral requirements for two different reasons. Without collusion about risk taking, a CCP offering diversication of risk cannot selectively forgo incentives for transactions that use collateral only for insurance. With collusion about risk taking, a CCP needs to charge collateral in line with the worst counterparty quality to control risk taking. Requiring more collateral reduces market liquidity and worsens incentives causing a feedback effect that amplifies collateral costs.

description: The electromagnetic effect is studied on the short wavelength branch of the ion temperature gradient mode in the linear regime for the first time using a global gyrokinetic model. The short wavelength ion temperature gradient mode growth rate is found to be reduced in the presence of electromagnetic perturbations at finite plasma $β$. The effect on real frequency is found to be weak. The threshold value of $η_i$ is found to increase for the mode as the magnitude of $β$ is increased. The global mode structure of the short wavelength branch of the ion temperature gradient mode is compared with the conventional branch. The magnetic character of the mode, measured as the ratio of mode average square values of electromagnetic potential to electrostatic potential, is found to increase with increasing values of the plasma $β$. The mixing length estimate for flux shows that the maximum contribution still comes from the long wavelengths modes. The magnitude of the flux decreases with increasing $β$.

description: The [CII] 158 micron line is one of the strongest IR emission lines, which has been shown to trace the star-formation rate (SFR) of galaxies in the nearby Universe and up to $z \sim 2$. Whether this is also the case at higher redshift and in the early Universe remains debated. The ALPINE survey, which targeted 118 star-forming galaxies at $4.4 < z< 5.9$, provides a new opportunity to examine this question with the first statistical dataset. Using the ALPINE data and earlier measurements from the literature we examine the relation between the [CII] luminosity and the SFR over the entire redshift range from $z \sim 4-8$. ALPINE galaxies, which are both detected in [CII] and dust continuum, show a good agreement with the local L([CII])-SFR relation. Galaxies undetected in the continuum with ALMA are found to be over-luminous in [CII], when the UV SFR is used. After accounting for dust-obscured star formation, by an amount SFR(IR)$\approx$SFR(UV) on average, which results from two different stacking methods and SED fitting, the ALPINE galaxies show an L([CII])-SFR relation comparable to the local one. When [CII] non-detections are taken into account, the slope may be marginally steeper at high-z, although this is still somewhat uncertain. When compared in a homogeneous manner, the $z>6 $ [CII] measurements (detections and upper limits) do not behave very differently from the $z \sim 4-6$ data. We find a weak dependence of L([CII])/SFR on the Lyman-alpha equivalent width. Finally, we find that the ratio L([CII])/LIR $\sim (1-3) \times 10^{-3}$ for the ALPINE sources, comparable to that of "normal" galaxies at lower redshift. Our analysis, which includes the largest sample ($\sim 150$ galaxies) of [CII] measurements at $z>4$ available so far, suggests no or little evolution of the L([CII])-SFR relation over the last 13 Gyr of cosmic time.

description: In 1993, with the launch of the latest iteration of the 'peace process' in Oslo, Norway, hopes rose around the world as a new and unprecedented agreement between Israel and the Palestinians was presented. Instead what occurred was a new "nakba" -- a catastrophe like that of 1948 when 700,000 Palestinians were expelled from their homes. In 1993 the Palestinians were to begin building institutions that many believed would lead to the long-awaited emergence of an independent Palestinian state. Something very different happened. Far from serving as a vehicle for Palestinian liberation, the Palestinian Authority has worked as an 'Arab facade,' veiling, entrenching, and even subsidizing Israeli colonial power behind the superficial covering of Palestinian national symbols. Though Israel recognized for the first time the existence of a legitimate Palestinian Arab collective, this recognition came at the cost of continued, even expanded, Israeli dominance, a new nakba.

description: Magnetic accreting white dwarfs in cataclysmic variables have been known to show bursts driven by different physical mechanisms; however, the burst occurrence is much rarer than in their non-magnetic counterparts. DW Cnc is a well-studied intermediate polar that showed a burst with a 4-magnitude amplitude in 2007. Here we report on a recent burst in DW Cnc observed by ASAS-SN that reached a peak luminosity of 6.6 $\times$ 10$^{33}$ erg~s$^{-1}$, another 4 mag increase from its quiescent high state level. The released energy of the burst suggests that these are micronovae, a distinctive type of burst seen in magnetic systems that may be caused by a thermonuclear runaway in the confined accretion flow. Only a handful of systems, most of them intermediate polars, have a reported micronova bursts. We also report on the reappearance of the negative superhump of DW~Cnc as shown by TESS and OPTICAM data after the system emerges from its low state and immediately before the burst. We further report on a new phenomenon, where the spin signal turns "on" and "off" on the precession period associated with the negative superhump, which may indicate pole flipping. The new classification of DW Cnc as a micronova as well as the spin variability show the importance of both monitoring known micronova systems and systematic searches for more similar bursts, to limit reliance on serendipitous discoveries.

description: The Pashtun population that straddles the border of Afghanistan and Pakistan has endured a history of conflict that continues to this day and has affected politics and governance in both Afghanistan and Pakistan. Amid complex tribal relations, the Pashtuns abide by a very strict cultural code of Pashtunwali that espouses underlying themes of independence, egalitarianism and honor -- themes which are apparent in both Pashtun and rival ethnic tribe's methods of dispute resolution -- and that promotes the respect of individual and tribal autonomy. Harnessing the aforementioned themes by promoting respect through positive interactions through focusing on commonalities in dispute resolution may aid the establishment of a culture of peace to combat the cycles of violence in Pashtun conflicts.

description: The parity-nonconserving asymmetry in the deuteron photodisintegration, $\vecγ+d\to n+p$, is considered with the photon energy ranged up to 10 MeV above the threshold. The aim is to improve upon a schematic estimate assuming the absence of tensor as well as spin-orbit forces in the nucleon-nucleon interaction. The major contributions are due to the vector-meson exchanges, and the strong suppression of the pion-exchange contribution is confirmed. A simple argument, going beyond the observation of an algebraic cancellation, is presented. Contributions of meson-exchange currents are also considered, but found to be less significant.

Effect of interactions on the quantization of the chiral photocurrent for double-Weyl semimetals

description: The circular photogalvanic effect (CPGE) is the photocurrent generated in an optically active material in response to an applied ac electric field, and it changes sign depending on the chirality of the incident circularly polarized light. It is a non-linear dc current as it is second-order in the applied electric field, and for a certain range of low frequencies, takes on a quantized value proportional to the topological charge for a system which is a source of nonzero Berry flux. We show that for a non-interacting double-Weyl node, the CPGE is proportional to two quanta of Berry flux. On examining the effect of short-ranged Hubbard interactions upto first-order corrections, we find that this quantization is destroyed. This implies that unlike the quantum Hall effect in gapped phases or the chiral anomaly in field theories, the quantization of the CPGE in topological semimetals is not protected.

description: BL Lacertae objects (BL Lacs) represent a large fraction (22\%) of gamma-ray sources in the Third Fermi Large Area Telescope catalog (3FGL). Nearly half of the BL Lac population remains without a redshift because of their featureless optical spectra. We aim to increase the number of BL Lacs with a redshift measurement by using the photometric technique. For this work, we have used 6 Swift-UVOT filters and SDSS g,r,i,z optical filters mounted on the 0.65 m SARA-CTIO located in Chile and the 1.0 m SARA-ORM in Canary Islands. A sample of 45 sources was selected from the 3FGL catalog for which photometry was performed in 10 optical and UV filters to obtain redshift measurements. We found 3 sources with z>1.3 while reliable upper limits have been derived for 17 sources. The results presented here bring the total number of high-z (z>1.3) BL Lacs to 29.

description: Cluster Dynamical Mean Field Theories are analyzed in terms of their semiclassical limit and their causality properties, and a translation invariant formulation of the cellular dynamical mean field theory, PCDMFT, is presented. The semiclassical limit of the cluster methods is analyzed by applying them to the Falikov-Kimball model in the limit of infinite Hubbard interaction U where they map to different classical cluster schemes for the Ising model. Furthermore the Cutkosky-t'Hooft-Veltman cutting equations are generalized and derived for non translation invariant systems using the Schwinger-Keldysh formalism. This provides a general setting to discuss causality properties of cluster methods. To illustrate the method, we prove that PCDMFT is causal while the nested cluster schemes (NCS) in general and the pair scheme in particular are not. Constraints on further extension of these schemes are discussed.

title: The effect of eyespot caused by Oculimacula yallundae and O. acuformis on yield of winter wheat
Creators: name: Ray, Rumiana V
Publisher: name: The Open University
Year: 2004

description: Field experiments (2000-2002) were carried out to determine the effect of eyespot caused by Oculimacula yallundae and O. acuformis (formerly known as W-type and R-type, respectively) on yield or lodging resistance of winter wheat and to identify any differences in the development of the two pathogens throughout the season. A field experiment on artificially inoculated wheat was designed to clarify the effects of the two Oculimacula spp. on plant characteristics associated with lodging resistance and on yield of individual shoots and whole crop. Overall yield of winter wheat in the absence of lodging was reduced by 11% and 6% by eyespot caused by O. acuformis and O. yallundae respectively. Both species reduced the stem safety factor associated with lodging resistance, indicating their ability to cause lodging in winter wheat by reducing stem-bending strength. The ability of O. acuformis to cause significant yield loss was demonstrated in a series of fungicide efficacy experiments in early-drilled winter wheat. Oculimacula acuformis developed more and caused greater yield loss in the first winter wheat in which other stem-base pathogens were absent in the early growth stages of the crop. Fungicide mixtures containing cyprodinil were consistently more effective in controlling eyespot caused by O. acuformis in first, second and third winter wheat crops. Positive relationships were observed between DNA concentrations of O. acuformis, O. yallundae and M. nivale throughout the growing season, indicating that these species co-existed within the crop. While the DNA of M. nivale consistently increased more up to GS 39 in different field experiments, DNA of Oculimacula spp. increased at different times in the growing season and these increases were sometimes associated with the relative quantities of DNA of M. nivale at the early growth stages.

description: We review the method of blocking of topological defects from continuum used as a non--perturbative tool to construct effective actions for these defects. The actions are formulated in the continuum limit while the couplings of these actions can be derived from simple observables calculated numerically on lattices with a finite lattice spacing. We demonstrate the success of the method in deriving the effective actions for Abelian monopoles in the pure SU(2) gauge models in an Abelian gauge. In particular, we discuss the gluodynamics in three and four space--time dimensions at zero and non--zero temperatures. Besides the action the quantities of our interest are the monopole density, the magnetic Debye mass and the monopole condensate.

Conflicts in Uganda since 1990
Creators: name: Moore, Michael Patrick
Publisher: name: American University
Year: 2023

description: The civil conflict literature explains the emergence and longevity of rebel movements by describing the structural factors in states coincident to conflict onset and extended conflict duration. In Uganda, the Lord's Resistance Army rebellion is in its third decade of existence and while the conflict literature provides some insight into the origins and endurance of the rebellion, the literature does not explain the responses of the government of Uganda to the rebellion. Instead, the actions and intentions of the Ugandan government are best explained by Uganda's status as an electoral authoritarian regime.
