description: The grape production chain has unique importance regarding to generate income and employment for many regional economies. However, in recent years, international trades in this sector, as well as the entire fruit sector, have been facing the imposition of various non-tariff measures, including sanitary, phytosanitary and technical. Thus, this paper analyzes the effects of sanitary, phytosanitary and technical rules imposed by importing countries of the Brazilian grape, from 1995 to 2009. To this end, we made an analysis of inventory and an econometric approach, in which we used the gravity model, in order to verify the impact of such measures on the Brazilian shipments of grape. The results found in the inventory analysis showed a positive relationship between changes in the number of notifications and import trends. As for the econometric model, the possibility of such measures have negatively affected the trading was disregarded and, in the case of sanitary and phytosanitary measures, a positive relationship with grape exports was found, i.e., they helped trades and effects of technical measures on exports were zero.

description: We investigate the hypothesis that the conversion of forest and pasture land to cropland in Brazil decreases yields by 50%. Such hypothesis is being used by the California Air Resource Board to estimate the greenhouse gas emissions from indirect land use changes due to the expansion of biofuels production. We formulate several econometric models to test such hypothesis. The results from the majority of the models indicate that yields do not decrease under the expansion of cropland area in the country, or the decrease in yields is very small. Therefore, our results indicate the need for revising and correcting the parameters in the Californian low carbon emissions policy.

description: The International Year of Cooperatives (2012) was established by the United Nations (UN) to highlight the importance of cooperatives for social and economic development. Hence, considering the role of cooperatives in the Brazilian rural sector, this article makes an analysis of scientific literature on cooperatives and cooperativism concerning the main journal of the Brazilian Society of Economics, Administration and Rural Sociology (Sober), the Journal of Economics and Rural Sociology (RESR). The aim is to determine the intensity of work on the topic as well as identify the main researchers and theoretical approaches. The findings showed that there are a small number of articles related to the topic and their references are mainly composed by economists. The analysis also concluded that the focus was related to economic issues like performance and profitability. Finally, we can also conclude that the key theoretical approaches of these scientific works under investigation rely primarily on Local Productive Arrangements and on The New Institutional Economics.

description: In recent years, solid state silicon photo multipliers (SiPM) have emerged as good substitutes to conventional photo multiplier tubes (PMT), as robust, compact and easy-to-handle alternatives. Development of these detectors started already in the 1990s and has since then steadily progressed. While analogue SiPMs are still mostly used, since they are superior in terms of dark count rate, particle detection efficiency, etc., a digital SiPM has the advantage of producing purely digital data. This thesis project is based on previously created simulations, which was developed by one of my previously MSc thesis students [1] and is part of the ongoing EU funded project “Positron Annihilation Detection beyond the limits” (PALADIN), which aims to improve coincidence timing performance in the range of sub-100 ps FWHM timing resolution. In this thesis different experimental setups are compared with simulations performed within the GEANT4 framework. First, the plausibility of the physics applied in the simulation is examined and compared with theoretical predictions. Furthermore, the simulation was adapted and compared to an experimental setup built and investigated at TU Delft . A system with two DPC-tiles and a point source, which randomly generates 511 keV back-to-back photons was created. According to the experimental setup, scintillator crystals with a base area of 3 x 3 mm2 and variable lengths were simulated. The data obtained from the simulation were analyzed with a tool, created within the framework ROOT, developed by the author,
Secure file system versioning at the block level
Creators: name: Wires, Jacob Taylor
Publisher: name: University of British Columbia
Year: 2010

description: Information is capital; disk space is a mere commodity. Versioning file systems offer an appealing storage model that prevents users from unintentionally deleting or overwriting important data by transparently retaining old versions. However, improving storage reliability by adding versioning to a file system is problematic in two important ways. First, the complexity of file systems and the operating systems in which they reside leaves data vulnerable to bugs and viruses, even when versioning is added. Second, the mission-critical nature of file systems makes users and OS vendors justifiably hesitant to adopt new file system features like versioning, regardless of the potential benefits they might provide. This thesis presents VDisk, a block layer system capable of providing file-grain versioning to existing, unmodified file systems. VDisk features a novel division of labor to enhance security and reliability. Write-access to versioned data is restricted to two very simple, reliable, file system agnostic components: a block logger and a log cleaner. These crucial components are isolated in a virtual machine, where they are protected from the errors and attacks that plague operating systems. More complicated, untrusted, read-only utilities operate in user space. These utilities, which are free to use sophisticated, off-the-shelf tools not appropriate for trusted kernels, support version browsing and reconstruction without degrading system reliability. VDisk employs a policy-driven approach to block reclamation. A retention policy specifies a set of constraints that describe which file versions must be retained and which need not be. A user-space tool periodically invokes the secure cleaner by submitting a set of delete requests along with a proof that these requests satisfy the retention policy. The secure cleaner verifies the proof and reclaims the specified blocks if applicable. Experimental results show that the cleaner is capable of reclaiming more than 80% of logged data.
title: Non-EU interest groups in Brussels: explaining the lobbying success of foreign interest groups in EU energy policy
Creators: name: Popovic, Ivana
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2019

description: Although the number of non-EU interest groups seeking to exert political influence in Brussels has been rising, research examining factors behind their success is scarce. This thesis contributes towards filling this gap by examining the success of foreign groups in the energy policy domain. Specifically, it examines how the European Commission’s initial preferences on both - the policies under consideration as well as the involved non-EU interest groups - affect the groups’ prospects of lobbying successfully. Employing process-tracing and cross-case comparison, the thesis explores four cases of Commission proposals covering the main aspects of the EU energy policy: competitiveness, sustainability and security. The extant literature on lobbying as information exchange assumes that the Commission has strong preferences regarding outcomes, but not on policy measures generating the desired outcomes. Interest groups, in return, shape a Commission’s proposal by providing expertise on which policies will lead towards the outcomes. The thesis complements this literature by arguing that in some cases, decision-makers have strong preferences concerning both - the outcomes and means necessary to achieve them - thus making interests groups’ attempts to alter their positions less likely to succeed. However, in the absence of the Commission holding strong views on policies, there is no guarantee that an interest group will be successful. Instead, a group’s success is affected by its status within the Commission. Drawing on research on the insider/outsider status of lobbyists, the thesis finds evidence that insiders are more likely to lobby successfully than outsiders. It contributes to this strand of literature by introducing an additional criterion underpinning the insider/outsider distinction, which concern specifically non-EU interest groups. Thus, the research suggests that a foreign interest group’s prospect of lobbying successfully is affected by the Commission’s positions on policies and involved lobbyists: how strong its initial view on issues under consideration is, as well as whether it sees interest groups as “insiders” or “outsiders”.

description: This paper characterizes the farmers of Petrolina-Juazeiro Polo depending on the adoption of strategies of product diversification to mitigate a variety of risks. To that end, were collected 173 observations and an econometric model, ordered logit, was applied to identify factors that influence the probability of the producer to diversify their production. The estimation of the econometric model suggests that the main factors influencing diversification of production at the pole are: size (small farmer), experience, contracts, sales to middlemen, cultivation of main crops (banana, coconut, guava, mango and grape), association, technical assistance, certification, post-harvest care and internet access procedures. The investigation of these relations becomes relevant to the formulation of policies to encourage the adoption of management strategies to reduce risks in the region, currently concerned with the specialization of activities and the vulnerability of producers face to demand shocks.
Designing with Static Capabilities and Effects: Use, Mention, and Invariants

Publisher: name: arXiv
Year: 2020
Subjects: subject: Programming Languages (cs.PL)
subject: FOS: Computer and information sciences

description: Capabilities (whether object or reference capabilities) are fundamentally tools to restrict effects. Thus static capabilities (object or reference) and effect systems take different technical machinery to the same core problem of statically restricting or reasoning about effects in programs. Any time two approaches can in principle address the same sets of problems, it becomes important to understand the trade-offs between the approaches, how these trade-offs might interact with the problem at hand. Experts who have worked in these areas tend to find the trade-offs somewhat obvious, having considered them in context before. However, this kind of design discussion is often written down only implicitly as comparison between two approaches for a specific program reasoning problem, rather than as a discussion of general trade-offs between general classes of techniques. As a result, it is not uncommon to set out to solve a problem with one technique, only to find the other better-suited. We discuss the trade-offs between static capabilities (specifically reference capabilities) and effect systems, articulating the challenges each approach tends to have in isolation, and how these are sometimes mitigated. We also put our discussion in context, by appealing to examples of how these trade-offs were considered in the course of developing prior systems in the area. Along the way, we highlight how seemingly-minor aspects of type systems -- weakening/framing and the mere existence of type contexts -- play a subtle role in the efficacy of these systems.

description: In this paper, we calculate the quantum time delays for neutron scattering off the Earth's linear gravitational potential. The quantum time delays are obtained by subtracting the classical returning time (CRT) from the Wigner time, the dwell time and the redefined Larmor time respectively. Different from the conventional definition, our Larmor time is defined by aligning the magnetic field along the neutron propagation direction, and this definition does give reasonable results for motions through a free region and a square barrier. It is worth noting that in the zero magnetic field limit, the Larmor time coincides well with the CRT, which is due to the special shape of linear barrier, and may have some relevance to the weak equivalence principle. It is also found that the classical forbidden region plays an essential role for the dwell time $τ_{_\mathrm{DW}}$ to match with the CRT, and the difference between the dwell and the phase times, \ie, the self-interference time delay, is barrier shape sensitive and clearly shows the peculiarity of the linear barrier. All the time delays are on the order of sub-millisecond and exhibit oscillating behaviors, signaling the self-interference of the scattering neutron, and the oscillations become evident only when the de Broglie wavelength $λ_k=2π/k$ is comparable to the characteristic length $L_c=[2m^2g/\hbar^2]^{-1/3}$. If the time delay measurement is experimentally realizable, it can probe the quantum nature for particle scattering off the gravitational potential in the temporal domain.

description: This study aimed to evaluate the Pronaf ’s ability to help reducing the gap between potential yield and actual output of agriculture in Tocantins. In terms of methodology, in addition to descriptive analyses, linear regression of the average and quantile regression were used. The research focused on Tocantins State, covering all municipalities (units of analysis), from 2002 to 2009. It was highlighted: the relative importance of agriculture for the economy in Tocantins, the significant participation of family agriculture in total industry output and the significant presence of Pronaf, which, apart from helping the process of legitimizing the family farm, as noted in early studies, has been shown capable to stimulate the production of plant and animal municipalities. Moreover, given the specificities of Pronaf in Tocantins, in terms of coverage and resource allocation, it is assumed that the findings give the program characteristics that also contribute for the process of reducing inequality in the state. However, although the program deserves the attention of policy makers, given their ability to stimulate local agricultural production, one must conceive it as a complementary intervention, since the family work, as recorded in literature, proved to be crucial in the productive performance of family farming.

description: Comprehensive low-temperature specific heat data C(T,H) of Na_0.35CoO2-1.3H_2O with temperature T down to 0.6 K and the magnetic field H up to 8 T are presented. For the normal state, the values of gamma_n=13.94 mJ/mol K2, and Debye temperature 362 K are reported. At zero field, a very sharp superconducting anomaly was observed at Tc=4.5 K with DeltaC/gamma_nTc=1.45. The superconducting volume fraction is estimated to be 47.4 % based on the consideration of entropy balance at Tc for the second-order superconducting phase transition. In the superconducting state, the electronic contribution C_es at H=0 can be well described by the model of the line nodal order parameter. In low H, gamma(H) H^1/2 which is also a manifestation of the line nodes. The behaviors of both Tc(H) and gamma(H) suggest the anisotropy of Hc2 or possible crossovers or transitions occurring in the mixed state.

A Conservative Discontinuous Galerkin Discretization for the Chemically Reacting Navier-Stokes Equations

description: We present a detailed description and verification of a discontinuous Galerkin finite element method (DG) for the multi-component chemically reacting compressible Navier-Stokes equations that retains the desirable properties of DG, namely discrete conservation and high-order accuracy in smooth regions of the flow. Pressure equilibrium between adjacent elements is maintained through the consistent evaluation of the thermodynamics model and the resulting weak form, as well as the proper choice of nodal basis. As such, the discretization does not generate unphysical pressure oscillations in smooth regions of the flow or at material interfaces where the temperature is continuous. Additionally, we present an hp-adaptive DG method for solving systems of ordinary differential equations, DGODE, which is used to resolve the temporal evolution of the species concentrations due to stiff chemical reactions. The coupled solver is applied to several challenging test problems including multi-component shocked flows as well as chemically reacting detonations, deflagrations, and shear flows with detailed kinetics. We demonstrate that the discretization does not produce unphysical pressure oscillations and, when applicable, we verify that it maintains discrete conservation. The solver is also shown to reproduce the expected temperature and species profiles throughout a detonation as well as the expected two-dimensional cellular detonation structure. We also demonstrate that the solver can produce accurate, high-order, approximations of temperature and species profiles without artificial stabilization for the case of a one-dimensional pre-mixed flame. Finally, high-order solutions of two- and three-dimensional multi-component chemically reacting shear flows, computed without any additional stabilization, are presented.

description: We have mapped with the IRAM interferometer at Plateau de Bure (PdBI) the 12CO emission towards intergalactic star forming regions located in the tidal tail stemming from NGC7319, in the Stephan's Quintet compact group of galaxies. The 13CO emission of the same region was observed with the IRAM 30m telescope and optical spectroscopy of several HII regions in the area were obtained with the Calar Alto 3.5m telescope. We recovered with the interferometer about 50% of the CO(1-0) total emission that had been earlier measured with single dish observations. We find two main areas of CO emission: (i) an elongated region towards the area known as SQ B where a Tidal Dwarf Galaxy could currently be forming (ii) a barely resolved area at the tip of the optical tidal arm. Both regions follow dust lanes visible on HST images and their CO peak coincides spatially exactly with the maximum of the Halpha line emission. In SQ B, there is furthermore very good kinematical agreement between the CO, Halpha and HI components. We conclude from these coincidences that the gaseous matter found in quantities in the area is physically associated to the optical tidal tail and thus that the intergalactic atomic hydrogen there was expelled from NGC7319. Furthermore, the relatively high oxygen abundances (about solar) estimated from the optical spectra of the HII regions imply that the gas feeding the star formation originated from the inner regions of the parent galaxy. In SQ B, we derive from different tracers a star formation rate of 0.5 \msun/yr. The inferred molecular gas consumption time of 0.5 Gyr lies in the range of values found for spiral and starburst galaxies. On the other hand, the ratio of 12CO/13CO>25 is much higher than the values found in disks of spiral galaxies. A relatively low opacity for the 12CO gas is the most likely reason.

description: This study aims to assess the effects of different objectives contained in the notifications applied to the TBT and SPS Agreements of the World Trade Organization had on international trade in different agrifood products between 1996 and 2010. For this purpose, we used a gravity model, estimated by the method of sample selection. The results showed that notifications for the purposes of consumer information contributed to the increase of the trade. Similarly, when the justifications of goals of notifications were combating epidemics worldwide, such as Avian Influenza, Bovine Brucellosis and other diseases, the international trade was favored. For other objectives, such as food safety, animal health, plant protection and conformity assessment, the effects were not standardized. We concluded that, if the countries disclose the meeting of the requirements of the TBT and SPS notifications, trade will be expanded. Thus, trade policies and business strategies can use labels and medias to disclose how the requirements contained in the notifications were met. Therefore, the gains from trades can be expanded.

description: The European Union (EU) still retains genetically modified (GM) crop applications within its agriculture and on the EU market. The current EU non-GM crop regime is in fact a ‘fictitious’ or ‘virtual’ non-GM crop regime that has developed into a ‘wicked’ problem. Any progress towards resolving this impasse, either in favour or against GM crops and their applications, is extremely difficult due to the inherent nature of the problem and the high level of conflict, discord and complexity involved. Top-down decisions are ineffective as a solution, which was clearly demonstrated by the failure to induce change when the GM potato Amflora was resolutely authorised for cultivation in the EU. True solutions require multi-level stakeholder engagement and a common understanding of a shared problem to break the impasse in the EU. Reaching this shared understanding remains a major - albeit interesting - challenge for future research

description: This study investigated the impact of pH heterogeneities on large scale CHO fed batch cultivations by the usage of a two-compartment scale down system. It is known that base addition from the top of bioreactors leads to a pH gradient as a consequence of long mixing times. These pH heterogeneities are assumed to have an influence on the physiology and the productivity of recombinant protein producing mammalian cells. Therefore, an experimental approach was developed to determine the size and the average pH of an alkaline zone, which can occur in a 10 m3 bioreactor, with a bench scale reactor. To determine the size of the alkaline zone, a bromthymolblue indicator was used to display the formation of the alkaline zone. The average pH of the alkaline zone was determined by using several pH probes placed in different areas of the bioreactor. We found that base addition from the top of a bioreactor leads to an alkaline zone with a volume of 5% of the initial reactor volume and an average pH amplitude of 0.25 units at a mixing time of 120 s. This experimental method for the determination of alkaline zone parameters could be used as an addition to CFD simulations. An alkaline zone with the obtained parameters was subsequently mimicked in CHO Fed Batch cultivations which were carried out with a two-compartment scale down system. In comparison to a control cultivation without an alkaline zone, no obvious changes in growth behaviour nor in the productivity of the cells could be observed. Further it was demonstrated that the formation of metabolites like lactate, ammonium or the uptake of glucose are not affected by the presence of an alkaline of this size and pH. This work extends the findings of previous studies in the research field of pH heterogeneities since it was the first time that an alkaline zone of such a low size and pH amplitude was mimicked. Furthermore, the results suggest that submerse addition of the base in large scale cultivations might not be necessary.

description: A dynamic wetting problem is studied for a moving thin fiber inserted in fluid and with a chemically inhomogeneous surface. A reduced model is derived for contact angle hysteresis by using the Onsager principle as an approximation tool. The model is simple and captures the essential dynamics of the contact angle. From this model we derive an upper bound of the advancing contact angle and a lower bound of the receding angle, which are verified by numerical simulations. The results are consistent with the quasi-static results. The model can also be used to understand the asymmetric dependence of the advancing and receding contact angles on the fiber velocity, which is observed recently in physical experiments reported in Guan et al Phys. Rev. Lett. 2016.

description: We study the crossover from BEC to BCS pairing for dilute systems but with a realistic finite-range interaction. We exhibit the changes in the excitation spectrum that provide a clean qualitative distinction between the two limits. We also study how the dilute system converges to the results from a zero-range pseudo-potential derived by Leggett.

Using haptics to address mobile interaction design challenges : prototyping and user evaluation with a handheld tactile display
Creators: name: Luk, Joseph Kurachi

description: Current user interfaces for mobile and handheld computing platforms principally offer user interaction through the visual and auditory modalities. However, mobile devices are often used in contexts where vision and hearing are impaired. At the same time, more and more functionality is being layered upon mobile devices, while the physical size of the display and keypad has remained small. This limits the rate of information that can be exchanged between the user and the system, and poses an interaction design challenge. Haptics offers a potential solution by providing an additional modality that is also especially well-suited to the demands of portable, personal devices that are in contact with the user’s skin. In this work we identify ways that interaction through the sense of touch can enhance mobile user interfaces. We describe the synergistic process of design of user interaction concepts and novel handheld tactile display hardware based on the principle of piezoelectric actuated lateral skin stretch. Following the realization of the prototype hardware, we performed perceptual characterization studies to determine the expressive capabilities of the new device in the hands of a human user. Informed by the results from the initial user studies, we built and tested a handheld browser application with tactile enhancement. The results of user testing with the browser application suggest that the current implementation of directional tactile stimulation alone is not sufficient to enhance performance (task time) in spatial navigation; however, the user study also brought to light some encouraging qualitative feedback and ways to improve the interaction design and haptic feedback. By conducting a full iteration of a user-centred design process in haptics, we have provided a case study to inform future development efforts, a flexible platform for prototyping, and an indication of promising future directions for using haptics to solve mobile interaction design challenges.

description: In the recent past, risk and risk management in agriculture has risen on the agenda of farm managers. Amongst other things, the increased interest is inter alia attributed to the Capital Requirements Directives in the ‘Basel II’ agreement. In this article, we apply indicators of risk-adjusted returns, well known in the valuation of equity funds, to the context of pig production. Using a large data set of pig farm performance data, we demonstrate that different indicators of risk-adjusted returns do not necessarily lead to different results in the valuation of farms. We recommend using the Treynor Ratio in practical application. Our empirical analysis did not reveal a significant relationship between returns and risk.

description: To reach the US 2022 mandate of 136.3 billion litres of annual biofuel production, multiple sources must be integrated into the renewable biofuels supply chain. Energy cane appears well suited to help meet this mandate, particularly in Louisiana. Although not traditionally grown, production similarities to sugarcane make it an attractive option for Louisiana farmers if they are offered the ‘right price.’ If farmers are to switch hectares from sugarcane to energy cane, cellulosic ethanol processors must provide farmers an additional $2.84/MT and $3.41/MT on a third and fourth stubbling above breakeven to make the net revenue on a per tonne basis from energy cane equal to that of sugarcane. Providing farmers with the right monetary incentive is only part of the equation for ethanol processors, as they also need to determine if cellulosic ethanol from energy cane is competitive with corn ethanol. A breakeven analysis is utilized to determine the monetary incentive needed to cover the cost of production. An additional equation is used to evaluate the cost of cellulosic ethanol so that comparisons may be drawn between cellulosic costs and traditional corn ethanol costs. Our results indicate that this occurs at enzyme prices of $0.04/l (projected enzyme costs), irrespective of energy cane yields, stubbling length, and/or corn prices. Since 2007, enzyme costs for the lignocellulosic ethanol process have fallen by $0.07/l, which have increased the competitiveness of cellulosic ethanol relative to corn ethanol.

description: Maize is gaining importance in recent years as a promising crop aimed at boosting agricultural growth in Bangladesh. The present study explores the potential of maize expansion by examining its profitability and economic efficiency using a survey data of 300 farmers from three regions. Maize ranks first in terms of yield (7.98 t/ha) and return (BCR=1.63) as compared with rice and wheat. The economic efficiency of maize production is also estimated at a high 87%, although a substantial 15% [(100-87)/87)] cost reduction is still possible while maintaining current output level by eliminating technical and allocative inefficiency. Education positively contributes towards increasing efficiency while large farmers are relatively inefficient. Geography does matter. Efficiency is lower in Bogra region as compared with Dinajpur and Kushtia. Policy implications include investment in education, setting up appropriate price policies to stabilise prices and facilitation of the input markets for timely delivery of required inputs.

description: Während Autohersteller heutzutage in ihren neuesten Modellen immer mehr Fahrassistenzsysteme und gar vollautonome Software einbauen, sitzt aktuell die Mehrheit aller Autofahrer noch immer in Autos, die ohne diese Hilfstechnologien auskommen müssen. Bis der Zeitpunkt gekommen ist, an dem vollautonomes Fahren die Straßen vollständig erobert hat, werden vermutlich noch einige tausend Verkehrsunfälle durch menschliche Fehler passieren. Statistiken bestätigen: ein Großteil der Autounfälle passiert während dem Kurvenfahren. Um für mehr Sicherheit im Auto auch bei älteren Modellen beizutragen, stellt diese Arbeit ein neues System vor, welches Fahrern in Echtzeit vor und während dem Kurvenfahren assistiert. Das System ist konzipiert um sowohl in Cloud- als auch in der neuartigen, sogenannten Edge-Infrastruktur, ausführbar zu sein. Ziel von Edge-Computing ist es, Recheneinheiten näher zum Anwender beziehungsweise zum Datenerzeuger zu bringen. In der Arbeit präsentieren wir Lösungen zur GPS-Datenverarbeitung, zum Kombinieren der GPS-Daten mit externen Datenquellen sowie zur Berechnung von Kurven und deren Eigenschaften. Als Ergebnis wird ein Prototyp-System entworfen und implementiert welches in simulierten Verkehrssituationen getestet wird. Der Prototyp wird anhand Leistung und Datengenauigkeit evaluiert. Basierend auf dem Prototyp, werden schließlich Kosten geschätzt, um solch ein System für alle Fahrer in Österreich bereitzustellen.
description: Today, modern cars with advanced driver assistance systems (ADAS) and even fully autonomous driving software are on the rise and expectedly will reduce accidents in traffic in the future. But as of now, the vast majority of drivers still drive cars without these technologies. Until cars will be driving fully autonomous, human errors are going to lead to thousands of car accidents. Statistics show that one major cause of accidents is related to cornering. To contribute to safer driving in any type of car, in this thesis we introduce a novel system that assists drivers in real-time while cornering. The system is designed in a way that it can be deployed to both the cloud and/or the emerging edge-computing infrastructure. The goal of edge-computing is to move computational units closer to where the data is produced. We also contribute solutions to processing location data, using and combining external data sources and calculating curves and properties. As a result, we design and implement a prototype that is tested against simulated traffic scenarios. In the evaluation we show how the prototype behaves in terms of performance and data quality. Based on the prototype, we finally demonstrate how much it would approximately cost to serve all drivers across Austria.
Scalar self-force on a static particle in Schwarzschild using the massive field approach

description: We use the recently developed massive field approach to calculate the scalar self-force on a static particle in a Schwarzschild spacetime. In this approach the scalar self-force is obtained from the difference between the (massless) scalar field, and an auxiliary massive scalar field combined with a certain limiting process. By applying this approach to a static particle in Schwarzschild we show that the scalar self-force vanishes in this case. This result conforms with a previous analysis by Wiseman .
