description: The present work is dedicated to a better understanding of the stability properties of regularized lattice Boltzmann (LB) schemes. To this extent, linear stability analyses of two-dimensional models are proposed: the standard Bhatnagar-Gross-Krook (BGK) collision model, the original pre-collision regularization and the recursive regularized model, where off-equilibrium distributions are partially computed thanks to a recursive formula. A systematic identification of the physical content carried by each LB mode is done by analyzing the eigenvectors of the linear systems. Stability results are then numerically confirmed by performing simulations of shear and acoustic waves. This work allows drawing fair conclusions on the stability properties of each model. In particular, recursive regularization turns out to be the most stable model for the D2Q9 lattice, especially in the zero-viscosity limit. Two major properties shared by every regularized model are highlighted: (1) a mode filtering property, and (2) an incorrect, and broadly anisotropic, dissipation rate of the modes carrying physical waves in under-resolved conditions. The first property is the main source of increased stability, especially for the recursive regularization. It is a direct consequence of the reconstruction of off-equilibrium populations before each collision process, decreasing the rank of the system of discrete equations. The second property seems to be related to numerical errors directly induced by the equilibration of high-order moments. In such a case, this property is likely to occur with any collision model that follows such a stabilization methodology.

description: This paper uses Nevada data to conduct regression analyses of the relationship between sage grouse (Centrocercus urophasianus) population sizes and potential causal factors. This is policy-relevant because of current petitions for listing this species under the Endangered Species Act. A key feature is that, although monitoring of sage grouse has occurred for many decades, data collection methods and level of monitoring effort have not been consistent. To account for this feature we use, as dependent variables, standardized measures such as population counts and harvest (hunting success) per unit of effort. Preliminary findings suggest that such measures have been particularly sensitive to whether or not humans used strychnine for predator control, with normalized measures of grouse populations higher in years when strychnine was employed. Our results also suggest a positive association between the number of cattle on the range and normalized measures of grouse population. This is a controversial finding as some studies suggest a negative impact of cattle grazing on grouse. Our data do not include indications of the timing and precise nature of grazing practices and so should be interpreted with caution.

description: The rapid follow-up of gamma-ray burst (GRB) afterglows made possible by the multi-wavelength satellite Swift, launched in November 2004, has put under a microscope the GRB early post-burst behavior, This is leading to a significant reappraisal and expansion of the standard view of the GRB early afterglow behavior, and its connection to the prompt gamma-ray emission. In addition to opening up the previously poorly known behavior on minutes to hours timescales, two other new pieces in the GRB puzzle being filled in are the the discovery and follow-up of short GRB afterglows, and the opening up of the $z\simg 6$ redshift range. We review some of the current theoretical interpretations of these new phenomena.

description: This paper develops a single-season dynamic game between fishermen and regulators. Fishermen maximize the NPV of profits by their location choice in a system with congestion, adjustment costs, and adaptive, quota-driven, site closures. Simulation results reveal feedbacks between site-choice and closure decisions and suggest the usefulness of spatial policy instruments in reducing congestion externalities and costly congestion-averting expenditures.
Accelerated Detector - Quantum Field Correlations: From Vacuum Fluctuations to Radiation Flux

description: In this paper we analyze the interaction of a uniformly accelerated detector with a quantum field in (3+1)D spacetime, aiming at the issue of how kinematics can render vacuum fluctuations the appearance of thermal radiance in the detector (Unruh effect) and how they engender flux of radiation for observers afar. Two basic questions are addressed in this study: a) How are vacuum fluctuations related to the emitted radiation? b) Is there emitted radiation with energy flux in the Unruh effect? We adopt a method which places the detector and the field on an equal footing and derive the two-point correlation functions of the detector and of the field separately with full account of their interplay. From the exact solutions, we are able to study the complete process from the initial transient to the final steady state, keeping track of all activities they engage in and the physical effects manifested. We derive a quantum radiation formula for a Minkowski observer. We find that there does exist a positive radiated power of quantum nature emitted by the detector, with a hint of certain features of the Unruh effect. We further verify that the total energy of the dressed detector and a part of the radiated energy from the detector is conserved. However, this part of the radiation ceases in steady state. So the hint of the Unruh effect in radiated power is actually not directly from the energy flux that the detector experiences in Unruh effect. Since all the relevant quantum and statistical information about the detector (atom) and the field can be obtained from the results presented here, they are expected to be useful, when appropriately generalized, for addressing issues of quantum information processing in atomic and optical systems, such as quantum decoherence, entanglement and teleportation.

description: In this partly expository paper we discuss conditions for the global injectivity of $C^2$ semi-algebraic local diffeomorphisms $f:\mathbb{R}^n \to \mathbb{R}^n$. In case $n > 2$, we consider the foliations of $\mathbb{R}^n$ defined by the level sets of each $n-2$ projections of $f$, i.e., the maps $\mathbb{R}^n \to \mathbb{R}^{n-2}$ obtained by deleting two coordinate functions of $f$. It is known that if the set of non-proper points of $f$ has codimension greater than or equal to $2$ and the leaves of the above-defined foliations are simply connected, then $f$ is bijective. In this work we relate this simply connectedness with the notion of locally trivial fibrations. Then some computable regularity conditions at infinity ensuring such simply connectedness are presented. Further, we provide an equivalent statement of the Jacobian conjecture by using fibrations. By means of examples we prove that the results presented here are different from a previous result based on a spectral hypothesis. Our considerations are also applied to discuss the behaviour of some conditions when $f$ is composed with linear isomorphisms: this is relevant due to some misunderstandings appearing in the literature.
SECURITY IS LIKE OXYGEN: EVIDENCE FROM UGANDA

description: Since the early 1990s, Uganda has been one of Africa's fastest growing countries. However, at the sub-national level, growth has been uneven due to civil conflict in the northern region. Using a panel of household and community level data, this paper examines the links between security and economic growth. It is found that security is a pre-condition for successful economic development and that there is in fact a threshold level of security below which public investments in infrastructure and education have little impact on growth. Only when security exceeds this threshold do public investments stimulate economic growth. Economists and policy advisors living in peaceful countries often prescribe economic policies that hinge on the assumption of good security. In this manner, security, like oxygen, is taken for granted.

description: Households plan strategically for facing risks associated with livelihood security. Choosing a particular set of coping strategies depends on a number of factors including the types of crisis households face and options available. Often, poor households risk future income generating capacity for maintaining current food consumption. This paper examines strategies used by rural households for coping with the shocks and investigates whether there is any distinctive pattern in adopting these strategies. Using a cross section data set covering 1600 households from the northwestern Bangladesh, we estimate a trivariate probit model for explaining the adoption of coping strategies. Results indicate that choice of coping strategies depend on diversity and stability of household income sources. Households with higher education have greater access to stable incomes sources and have more income sources, and so are less likely to adopt ex-post coping strategies. Households with more assets are more likely to divest assets or obtain secured loans rather than rely on unsecured loans. Wealthier households are not less likely to adopt current adjustment strategies, suggesting that there is a general sequence of coping strategies that all households follow, irrespective of the assets they own.

Interaction induced magnetic field asymmetry of nonlinear mesoscopic electrical transport

description: We demonstrate that the nonlinear I-V characteristics of a two probe conductor is not an even function of magnetic field. While the conductance of a two-probe conductor is even in magnetic field, we find that already the contributions to the current which are second order in voltage, are in general not even. This implies a departure from the Onsager microreversibility principle already in the weakly nonlinear regime. Interestingly, the effect that we find is due to the Coulomb interaction. A measurement of the magnetic field asymmetry can be used to determine the effective interaction strength. As a generic example, we discuss the I-V characteristics of a chaotic quantum dot. The ensemble averaged I-V of such a cavity is linear: nonlinearities are due to quantum interference. Consequently, phase-breaking reduces the asymmetry. We support this statement with a calculation which treats inelastic scattering with the help of a voltage probe.

description: This study proposes an integrated approach to measuring the broader definition of scale economies proposed by Morrison and Siegel. The paper attempts to tackle the three unsolved problems in Morrison and Siegel, and thus will offer a methodological refinement and in the meantime make a significant contribution to the literature. Calculation of the total scale economies measures suggest Taiwan¡¦s production technology exhibit long-run increasing returns to scale in the presence of external economies. A comparison of the conventional measure of scale economies indicate a possible downward bias when short-run fixity as well as external economies from high-tech capital investment, R&E and human capital, are not explicitly recognized.

description: This study empirically estimates a multivariate binary choice model for four categories of food shopping store formats. The results indicate that in the Qingdao market, traditional counter parts such as wet markets and small grocery stores have been dominated by supermarkets and hypermarkets. At the same time, the rapid growth of hypermarkets in Qingdao is significantly challenging current supermarkets in this city, but they do not compete extensively with wet markets and small grocery stores. Further development of various categories of the food shopping store format is linked to store owned characteristics, potential interrelations among existing retail formats, as well as consumers' demographics and shopping habits.

We also present evidence that the star HATS-37A has an unresolved stellar companion HATS-37B, with a photometrically estimated mass of 0.654 M_sun.The planet HATS-38b has a mass of 0.074 +- 0.011 M_J (23.5 +- 3.5 M_earth) and a radius of 0.614 +- 0.017 R_J, and is on a P = 4.3750 days orbit around a V = 12.411 mag, 0.890 M_sun star with a radius of 1.105 R_sun. Both systems appear to be old, with isochrone-based ages of 11.46 +0.79-1.45 Gyr, and 11.89 +- 0.60 Gyr, respectively. Both HATS-37Ab and HATS-38b lie in the Neptune desert and are thus examples of a population with a low occurrence rate. They are also among the lowest mass planets found from ground-based wide-field surveys to date.

description: Economists frequently assess willingness to pay (WTP) for land preservation outcomes independent of information regarding policy implementation. The public, however, may not only be concerned with the consequences of land management, but also may have systematic preferences for policy procedures applied to achieve management goals. This paper examines relationships between WTP for land preservation outcomes and attributes of the policy process, considering stated preferences for farm and forest preservation in two Northeastern states. The approach departs from traditional welfare assessments in that it does not constrain attributes of the policy process to be utility-neutral. Results indicate that utility is influenced by policy process attributes, even after controlling for the influence of land use outcomes often correlated with specific policy techniques. Results suggest that even comprehensive specification of land use outcomes by stated preference instruments may be insufficient to prevent systematic shifts in WTP related to unspecified, yet assumed, policy process attributes.

description: We have studied the influence of alloying copper with amorphous arsenic sulfide on the electronic properties of this material. In our computer-generated models, copper is found in two-fold near-linear and four-fold square-planar configurations, which apparently correspond to Cu(I) and Cu(II) oxidation states. The number of overcoordinated atoms, both arsenic and sulfur, grows with increasing concentration of copper. Overcoordinated sulfur is found in trigonal planar configuration, and overcoordinated (four-fold) arsenic is in tetrahedral configuration. Addition of copper suppresses the localization of lone-pair electrons on chalcogen atoms, and localized states at the top of the valence band are due to Cu 3d orbitals. Evidently, these additional Cu states, which are positioned at the same energies as the states due to ([As4]-)-([S_3]+) pairs, are responsible for masking photodarkening in Cu chalcogenides.

description: In vielen Branchen werden bzw. sind die verschiedensten Arbeitsgänge automatisiert. Speziell im Bauwesen ist auch dieser Trend in den letzten Jahren zu erkennen. Viele Arbeitsprozesse wie Vorfertigung und Montage laufen schon mechanisch ab. Durch die Weiterentwicklung der Mikroelektronik und der Robotertechnik können bald sämtliche Prozesse vollautomatisch ablaufen. Bereits in Japan wurde durch das so genannte Smart-System ein Stahlskelettbau automatisch hergestellt. In dieser Arbeit soll eine Zusammenfassung aktueller Verbindungstechniken sowie Grundkenntnisse zu Fertigteilen und statischen Systemen im Stahlbeton-Skelettbau vermittelt werden. Aufbauend auf den grundsätzlichen Untersuchungen von Frau Anne Lauterbach, sollen die bautechnischen Voraussetzungen vertieft werden, die es gestatten, Baustellenmontagen vollständig zu mechanisieren und weitgehend zu automatisieren. Hauptziel ist, am Beispiel mehrgeschossiger Stahlbeton-Skelettbauwerke den aktuellen Stand der Verbindungstechnik im Stahlbeton-Fertigteilbau darzustellen und neue Möglichkeiten und Entwicklungstrends aufzuzeigen und durch statisch-konstruktive sowie technologische Betrachtungen zu untermauern. Weiterhin sind die Entwürfe zu den neuen Verbindungstechniken auf die Realisierbarkeit im statischen System zu untersuchen und auf Tauglichkeit für automatisierte Montagen zu bewerten.

Modeling the Semantics of States and State Machines

Year: 2020
Subjects: subject: Software Engineering (cs.SE)
subject: FOS: Computer and information sciences

description: A system s behavior is typically specified through models such as state diagrams that describe how the system should behave. According to researchers, it is not clear what a state actually represents regarding the system to be modeled. Standards do not provide adequate definitions of or sufficient guidance on the use of states. Studies show these inconsistencies can lead to poor or incomplete specifications, which in turn could result in project delays or increase the cost of the system design. This paper aims to establish a precise definition of the notion of states and state machines, a goal motivated by system modelers (e.g., requirement engineers) need to understand key concepts and vocabulary such as states and state machine, which are major behavioral modeling tools (e.g., in UML). State is the main notion of a state machine in which events drive state changes. This raises questions about the nature of these state-related notations. The semantics of these concepts is based on a new modeling methodology called the thinging machine applied to a number of examples of existing models. The thinging machine semantics is founded on five elementary actions that divide the static model into changes/states upon which events are defined.

description: Food quality has become an increasing concern in the public health arena over recent years. Food manufactures and processors hygiene performance plays a crucial part in producing safer food products. While there are inspections assessing plants' hygiene performance, there is little direct communication of performance measures to consumers. This paper uses survey data to determine consumer preferences among a set of four alternative food labels which report such plant level performance scores. How much information, as well as the format they most prefer, is compared using a range of econometric models. Results show that consumers prefer number scheme, larger volume of quality information and are generally consistent with their preference. These findings are mostly continuous across different types of consumers.

To answer this question, we use supermarket scanner data to estimate an incomplete demand system for dairy products. Based on these estimates, we simulate substitution effects among dairy products and the welfare impacts of price changes resulting from changes in milk marketing orders for various consumer groups. While we find little difference in own- and cross-price substitution elasticities of demand, the welfare effects of price changes vary substantially across demographic groups, with some losing and others winning from this government program. Families with young children suffer from marketing orders, while wealthier childless couples benefit. Additionally, we find that households with lower incomes pay a larger percentage of their income due to marketing orders than those with higher income levels.

description: Renewable methanol as a marine energy carrier has great potential to achieve clean and carbon-neutral waterborne transport. FASTWATER, an EU-funded H2020 project, is aiming at fast-tracking the development and demonstration of methanol as a marine fuel with the focus on the research and development of the next generation marine engines operating with neat methanol.Methanol is particularly suitable for spark-Ignition operation which does not fit well with medium-speed, large-bore marine engines. The low piston speed will lead to lower flame speed, and the large bore means a longer distance for the flame to travel. When these two factors combine, the end gas would likely to reach auto-ignition conditions and knock would occur. However, compared to traditional SI fuel like gasoline, methanol has a higher octane number to resist auto-ignition, a higher flame speed for faster combustion and a higher heat of vaporization for intake charge cooling. These all contribute to lowering the knock tendency.To investigate the feasibility of operating on 100% methanol with spark-ignition in a medium-speed marine engine, a virtual engine based on the DZ engine family manufactured by Anglo Belgian Corporation, part of the FASTWATER consortium, is created in a simulation environment. The methanol is introduced through port-fuel-injection to represent a retrofit from an existing diesel engine. The performance and emissions are evaluated with two knock-mitigating measures, retarding combustion phasing and reducing intake temperature.Through this study it was found that while reducing intake temperature is crucial in combating knock, the optimal strategy would be applying both knock-mitigating measures and operating the engine with relative air-fuel ratios between 1.5 to 2. With this strategy, the reference engine would potentially achieve knock-free operation with load and efficiency near its conventional diesel counterparts, and much lower NOx emissions.

description: Die heute erhältlichen Web-Content Management-Systeme (WCMS) verfügen über ein umfangreiches und breit gefächertes Angebot an Funktionen, die weit über die, zur Redaktion und zum Management von Internetpräsentationen, not-wendigen Grundanforderungen hinausgehen. Das macht diese Systeme in ih-ren Einsatz sehr flexibel und deckt vielfältige Anforderungen der Endanwender ab. Andererseits steigt durch die dadurch bedingte Komplexität der Arbeitsauf-wand erheblich und die Bedien- und Benutzerfreundlichkeit sinkt. Gerade für kleinere Internetpräsentationen, die ohne aufwendige Interaktionsmöglichkeiten aber auf häufig wechselndem Informationsangeboten aufwarten, wäre dies in seiner Grundfunktionalität reduziertes System vorteilhaft. Ein solches reduziertes Web-Content Management-System soll während der Diplomarbeit entworfen und beispielhaft implementiert werden. Als Ausgangs- und Orientierungspunkt soll hierzu die Internetpräsentation der Professur Informations- und Wissensverarbeitung dienen. Zur softwaretechnischen Umsetzung sind PHP und MySQL in Verbindung mit regulären HTML und CSS zu be-nutzen. Für das weitere Vorgehen müssen zunächst die Struktur und der Aufbau der Internetpräsentation der Professur analysiert, strukturiert und formalisiert werden. Anschließend sind die am häufigsten professionell genutzten Webcontent-Managementsysteme (TYPO3 und weitere siehe www.opensourcecms.com) hinsichtlich der durch sie angebotenen Grundfunktionalitäten und der verwen-deten Templates und Vorlagen zu untersuchen. Die aus dieser Analyse resultierenden Ergebnisse sind Ausgangspunkt für die Anforderungsdefinition des zu erstellenden Mini-WCMS. Anschließend ist eine prototypische Implementierung des theoretisch entstan-denen Systems, zugeschnitten auf die speziellen Bedürfnisse der Professur, vorzunehmen und hinsichtlich seiner Eignung zu diskutieren.

description: We report on the critical properties of minimaly-polydisperse crystals, hexagonal in 2d and face-centered cubic in 3 dimensions, at the isostatic jamming point. The force and gap distributions display power-law tails for small values. The vibrational density of states (VDOS) is flat. The scaling behavior of forces of extended floppy modes and the VDOS are universal and in agreement with an infinite-dimensional mean-field theory and maximally amorphous packings down to 2 dimensions. The distributions of gaps and forces of localized floppy modes of near-crystals appear non-universal. A small fraction of normal modes exhibit partial localization at low frequency. The majority of normal modes is delocalized exhibiting a characteristic inverse participation ratio scaling with frequency. The packing fraction and order at jamming decay linearly and quadratically respectively with polydispersity down to the maximally amorphous state.

description: A planar Maxwell-Chern-Simons-Proca model endowed with a Lorentz-violating background is taken as framework to investigate the electron-electron interaction. The Dirac sector is introduced exhibiting a Yukawa and a minimal coupling with the scalar and the gauge fields, respectively. The the electron-electron interaction is then exactly evaluated as the Fourier transform of the Moller scattering amplitude (carried out in the non-relativistic limit) for the case of a purely time-like background. The interaction potential exhibits a totally screened behavior far from the origin as consequence of massive character of the physical mediators. The total interaction (scalar plus gauge potential) can always be attractive, revealing that this model may lead to the formation of electron-electron bound states.

description: This paper investigates whether the assumption of Brownian motion often used to describe commodity price movements is satisfied. Using historical data from 17 commodity futures contracts specific tests of fractional and ordinary Brownian motion are conducted. The analyses are conducted under the null hypothesis of ordinary Brownian motion against the alternative of persistent or ergodic fractional Brownian motion. Tests for fractional Brownian motion are based on a variance ratio test. However, standard errors based on Monte Carlo simulations are quite high, meaning that the acceptance region for the null hypothesis is large. The results indicate that for the most part, the null hypothesis of ordinary Brownian motion cannot be rejected for 14 of 17 series. The three series that did not satisfy the tests were rejected because they violated the stationarity property of the random walk hypothesis.

description: For many decades scholars converse how to correctly include the Old Babylonian Empire into the absolute timeline of history. A cuneiform text from the series Enuma Anu Enlil (EAE #20) reports on the destruction of Babylon after a lunar and solar eclipse. Eclipses provide a great tool for examining historic events, and this account will be our basis for the investigation of eclipse pairs to be fitted into the various chronologies proposed. We consider three interpretations of that text: literal understanding, the inverted sequence of the two eclipse types, and a relocation of the setting to Akkad. All variants show imperfections. The least complications emerge when the account draws upon the third option, i.e. if it is allotted to 2161 BCE, as the year would mark the end of the Gutian rule in Akkad. But in any case the account seems to support rather the Long Chronology than any other. When dealing with eclipses such far back in time, we also allow for the shift of the visibility zone in regard to the irregular deceleration of Earth's rotation.

description: The full impact of an investment in a management information system (MIS), such as precision agriculture (PA), comes from improved managerial decision making throughout the whole farm and not just from improvements in a specific part of the farm. This study was conducted to determine whether the adoption of PA had a positive impact on whole-farm profitability. To overcome problems of simultaneity and self-selection in the adoption decision of PA, this study used a two stage econometric model using data from farms in Southwest Minnesota. The PA adoption decision was evaluated in the first stage, and the impact of adopting PA was evaluated in the second stage. The whole farm rate of return to assets (ROA) was used to measure the impact of PA. For all 212 farms in the dataset, the adoption of precision agriculture was explained significantly (p<0.1) by two variables: positively by the farmer's self-described soil variability and negatively by the level of non-farm income. For the 63 crop farms in the dataset, adoption of PA was explained significantly (p<0.1) only by the farmer's self-described soil variability. The adoption of PA was estimated to have a significant (p<0.1) negative impact on ROA for the entire group of farms but was not significant when the farms were separated into crop farms only and into size clusters. PA's lack of significance in explaining ROA in the subgroups may be due to small sample size, the variability of ROA itself, the lack of fully implementing PA as an MIS, differences in management ability, and the availability of other farming methods that are just as profitable as PA.

description: Most trade barriers are, by their very nature, bi-lateral. Since most countries trade with more than one country in more than one product, these bilateral measures can have spillover effects, changing trading patterns among other countries and products. This paper looks at the effect of a bilateral trade barrier on trade flows within a three-country free-trading area. Specifically, this paper examines the trade distortion effects of the 1996 voluntary export restraint (VER) placed on tomato exports from Mexico to the United States. Has Mexico shifted its exports from the Unites States to Canada, and has Canada increased its exports to the United States? Has the VER caused Mexico to divert fresh tomatoes to the processing sector?
