Discrete-to-continuum limits of particles with an annihilation rule
No full textIn the recent trend of extending discrete-to-continuum limit passages for gradient flows of single-species particle systems with singular and nonlocal interactions to particles of opposite sign, any annihilation effect of particles with opposite sign has been sidestepped. We present the first rigorous discrete-to-continuum limit passage which includes annihilation. This result paves the way to applications such as vortices, charged particles, and dislocations. In more detail, the discrete setting of our discrete-to-continuum limit passage is given by particles on the real line. Particles of the same type interact by a singular interaction kernel; those of opposite sign interact by a regular one. If two particles of opposite sign collide, they annihilate; i.e., they are taken out of the system. The challenge for proving a discrete-to-continuum limit is that annihilation is an intrinsically discrete effect where particles vanish instantaneously in time, while on the continuum scale the mass of the particle density decays continuously in time. The proof contains two novelties: (i) the observation that empirical measures of the discrete dynamics (with annihilation rule) satisfy the continuum evolution equation that only implicitly encodes annihilation and (ii) the fact that, by imposing a relatively mild separation assumption on the initial data, we can identify the limiting particle density as a solution to the same continuum evolution equation

Caton et son Livre de bonnes meurs entre manuscrit et imprimé
No full textLe succès des Disticha Catonis, en latin et en français, s’est prolongé jusqu’au début du xvie siècle. La traduction de Jean Le Fèvre en particulier est passée sous les presses de Colard Mansion [1476-1484]), pour être ensuite copiée dans le ms Wien, ÖNB, 3391. Énième exemple d’un manuscrit tardif dérivé d’un imprimé, le Livre de bonnes meurs invite une fois de plus les éditeurs critiques à prendre en compte l’ensemble de la tradition d’un texte, quel que soit le medium

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Maintaining New Markets: Explaining Antitrust Enforcement in Central and Eastern Europe
No full textWhile others have examined the implementation and/or the stringency of enforcement of antitrust laws in post-socialist economies, this paper is the first study that attempts to explain the patterns of antitrust enforcement activity across post-socialist countries using economic and political variables. Using a panel of ten European post- socialist countries over periods ranging from 4 to 11 years, we find a number of significant factors associated with enforcement in these countries. For example, our results suggest that countries characterized by more unionization and less corruption tend to engage in greater antitrust enforcement of all types. Countries more successful in privatizing have filed fewer cases, while more affluent or developed countries investigate fewer cases of all types, consistent with an income-shifting motivation for antitrust. In general, countries have tended to increase their enforcement efforts over time
Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
