This article is a case study and rhetorical analysis of a specific scientific paper on a computer simulation in astrophysics, an advanced and often highly theoretical science. Findings reveal that rhetorical decisions play as important a role in creating a convincing simulation as does sound evidence. Rhetorical analysis was used to interpret the data gathered in this case study. Rhetorical analysis calls for close reading of primary materials to identify classical rhetorical figures and devices of argumentation and explain how these devices factor in the production of scientific knowledge. This article describes how abduction, dilemma, compensatio, aetiologia, and other tactics of argumentation are necessary in creating the simulation of a supernova. Ultimately, the article argues that rhetorical mechanisms may be responsible for making some simulations better and more sound than others.

"Der Aufsatz plädiert dafür, die Geschichte der wissenschaftlichen Computersimulation auf eine spezifisch medienhistorische Weise zu untersuchen. Nach einigen Vorschlägen zur Charakterisierung der Besonderheiten von Computersimulationen werden zwei Beispiele interpretiert (Management-Simulationen der 1960er und verkehrstechnische bzw. epidemiologische Simulationen der 1990er). Daraus leiten sich Fragen nach dem veränderten Status wissenschaftlichen Wissens, nach der Genese wissenschaftstheoretischer Konzepte und nach wissenschaftskritischen Optionen ab. </br></br>The paper suggests to analyze the history of scientific computer simulations with respect to the history of media. After presenting some ideas concerning the peculiarities of computer simulation, two examples (management simulations of the 1960s; traffic-related and epistemological simulations of the 1990s) are interpreted. From them, further questions concerning the status of scientific knowledge, the genesis of epistemological concepts and their critique are derived. "

This interdisciplinary case study explores information literacy policy in Ontario’s public education system. Using interviews with policy makers and a rhetorical analysis of information literacy policy documents, it finds Ontario’s current information literacy policy inadequate to the task of providing equitable student access to opportunities for information literacy development.Une étude cas interdisciplinaire explore la politique de littératie informationnelle du système d’éducation publique de l’Ontario. En utilisant des entrevues avec les décideurs et une analyse rhétorique des documents sur la politique de littératie informationnelle, il est démontré que la politique de littératie informationnelle actuelle de l’Ontario est inappropriée pour la mission qui vise à offrir aux étudiants un accès équitable aux possibilités de développement de la littératie informationnelle.

A computer simulation approach for engineering air-jet spun yarns is proposed, and the advantages of computer simulations over experimental investigations and stand-alone mathematical models are discussed. Interactions of the following factors in air-jet spun yarns are analyzed using computer simulations: yarn count and fiber fineness, fiber tenacity and fiber friction, fiber length and fiber friction, and number of wrapper fibers and wrap angle. Based on the results of these simulations, yarn engineering approaches to optimize strength are suggested.

Simulation Results

This work studies the aggregation of an synthetic ultraviolet absorbent, named 2-hydroxy-4-perfluoroheptanoate-benzophenone (HPFHBP), in the interface between two solvents which can not completely dissolve each other. The aggregation is studied by computer simulations based on a dynamic density functional method and mean-field interactions, which are implemented in the MesoDyn module and Blend module of Material Studios. The simulation results show that the synthetic ultraviolet absorbent diffuse to the interface phase and the concentration in the interface phase is greater than it in the solvents phase.

Distinctive Aspect

Abstract Because of the unique set of sources available, the Fayyum in Middle Egypt offers a unique case study of large-scale irrigation from antiquity to the Islamic period. A close reading of a cadastral survey of the province from 641/1243-4 shows that the distinctive aspect of the Islamic period was the local control of water supply and management. Drawing on the engineering experience of the villagers, water allocation and management in the gravity-fed canals of the Fayyum were in the hands of iqṭāʿ holders and tribal groups along the main canals, a pattern similar to that which pertained in mediaeval al-Andalus.

Contesting Aristotle: Science, Theology and the Resurrection of the Body in Methodius of Olympus’ De Resurrectione and the Dialogue of Adamantius

Abstract The contest over the resurrection of the body used the scientific authority of Aristotle as ammunition on both sides. Past scholars have read Methodius of Olympus as displaying an anti-Aristotelian bias. In contrast, through close reading of the entire text with attention to characterization and development of argument, I prove that Methodius of Olympus’ dialogue the De Resurrectione utilizes Aristotelian biology as a morally neutral tool. To put this into higher relief, I compare Methodius’ dialogue with the anonymous Dialogue of Adamantius, a text directly dependent upon the Methodius’ De Resurrectione, but which rejects arguments based on scientific reasoning. Reading Methodius’ De Resurrectione with greater attention to the whole and putting it in the context of its nearest parallel text retells the traditional story of early Christian resistance to Aristotle. Methodius of Olympus’ characters, although they view scientific knowledge as subordinate to philosophy, see it as neutral in and of itself.

In the manufacturing industry, managers and engineers are trying to sustain their competitiveness by achieving high output and productivity. There are some common problems such as waiting times, failures, reworks in production line that impose extra cost to the companies. Therefore, companies are striving to find methods in order to determine and deal with problems using different methods such as mathematical, statistical and computer simulation. The goal of this paper is to increase the total output production and to improve productivity using computer simulation and Taguchi method. This paper introduces a color manufacturing line as a case study which is simulated using arena 13.9 software. Following that the Taguchi method is applied to assess the effect of controllable and uncontrollable factors on the total output production. According to the result of JMP 10 software to conduct Taguchi experiment, the maximum desirability of productivity will be achieved when the value of factors such service rate of delpak machine=UNIF (30, 40), number of labor=14, inspection time=120 and number of Permil=5. Taguchi Method plays an efficient and suitable role in the process improvement, proposing adjustments that will provide an improvement in the productivity.
