The manuscript relationships of Rudolf von Ems’s Barlaam und Josaphat with special reference to rubrication

Zaenker, Karl August January 1974 (has links)
The medieval legend of the two Saints Barlaam and Josaphat has attracted wide attention since, in the nineteenth century, some of its roots were discovered in ancient Indie Buddha legends and parables. Our study limits itself to the German version by Rudolf von Ems, a free translation from a Latin source, written around 1225. Although this work was edited as early as 1818, it was not until the last decade that some detailed but rather opposite interpretations were devoted to it. All recent studies of Barlaam und Josaphat have been based on a reprint of Pfeiffer edition of 1843 which, however, has grave shortcomings: it takes only a few manuscripts and fragments into account selects their readings at random, and does not provide a reliable critical apparatus. Therefore, it seemed appropriate to work towards a new, truly critical text edition which would be beneficial to further investigations into meaning and structure of the work. Our first step was to locate all existing manuscripts and fragments and obtain photocopies of them. For the ensuing process of assessing their relationships in order to determine their individual value for a text reconsti-tution, we tried an approach different from traditional practice. Instead of basing a grouping on common readings or mistakes alone, we began by comparing the paragraph markings (rubricated initials) in the major manuscripts. We believe that they were placed originally to subdivide the narrative and that, generally, they were copied by later scribes and rubricators. During the transmissibn process involuntary or deliberate "misplacements" occurred which would show up in further copies and could thus indicate group characteristics. Therefore we listed all rubri-cation. marks in a comprehensive chart and calculated the overall agreement between the major manuscripts in percentage figures. The evaluation showed that the oldest two manuscripts C and D, as well as A and b have a very similar rubrica-tion pattern, probably still close to the original one. This likeness makes it difficult if not impossible to determine if another manuscript is related to either of these. On the other hand, a clear affinity could be established between the hitherto overlooked manuscripts G, M, and, to a lesser extent, E, as well as between W and L in the first half of the text and C and L in the second half. We had divided the total number of initials into four even sections (covering ca. 4000 verses) to see if the "agreement figure" of one manuscript to another changes markedly. A subsequent look at individual "spurious initials" (mostly faults in rubrication) confirmed the first results and established a third definite grouping, that of DKCKa (Ka is only represented by the text edition of 1818). A comparison of the smaller fragments followed in which the main criterion was their textual agreement with other manuscripts. The rubrication was also taken into account but not overemphasized since conclusive evidence was often lacking due to the shortness of most fragments. We found that in three cases fragments belonged together to one otherwise lost manuscript (dq, mF2, and el). Many of the fragments showed characteristics of the GEM-group, whereas only very few seemed related to either A, b, C, or D. This sampling of common variants and text omissions throughout the work served also to verify the results gained by the "initial method." In general, the above mentioned groupings were confirmed or slightly modified. It became clear that in some cases a straightforward text transmission (as represented in a stemma) cannot be assumed. Especially in the loosely related body of manuscripts A, b, (B), C, L, and W, there is strong evidence of contamination which would make a tentative classification futile. A critical edition should, in our view, follow the old reliable Freiburg codex D as lead manuscript and confront its text consistently with the readings and paragraphs of the other two large groupings, mainly C and G. The closing chapter outlines the spreading of Rudolf's Barlaam und Josaphat as documented in its manuscript tradition, from its limited Alpine origin to its popularity within the Teutonic Order of Knights in East Prussia until its last flowering in Southern Germany at the end of the fifteenth century. / Arts, Faculty of / Central Eastern Northern European Studies, Department of / Graduate

The challenges of curriculum changes in teaching economic and management sciences in schools in the Umhlathuze circuit

Phakathi, Sabelo Petros January 2018 (has links)
Submitted to the Faculty of Education in partial fulfilment of the requirements for the degree of Master’s in Education in the Department of Curriculum and Instructional Studies at the University of Zululand, 2018. / This study sets out to investigate the teaching of Economic and Management Sciences (EMS) as a subject in the context of curriculum change. The main aim of this study is to identify the challenges teachers face in teaching EMS, determine the suitable teaching strategies to be used to teach EMS and explore the effect of curriculum change in teaching EMS in schools at Umhlathuze Circuit. This study is located within the interpretivist-positivist paradigm and falls within mixed method research approaches. The research instruments used were questionnaires administered to EMS teachers, interviews, learner activities and teacher portfolios. The results show that EMS teachers are facing challenges with regards to the integrated teaching of Accounting, Business Studies and Economics. The results of the study reveal that EMS teachers are still teaching more of Business Studies and Economics while sacrificing the Accounting content. The time allocated to teach EMS is not enough which causes teachers to focus on curriculum coverage rather than ensuring that learners master the content taught. The shortage of textbooks and calculators was also identified as a major challenge in many schools. Many EMS teachers are either trained for at least a combination of two disciplines in EMS. Even the Heads of department are not fully equipped in all three disciplines within the EMS. It is recommended that time allocation for EMS be reviewed. There is a need for sufficient resources in schools to ensure effective teaching and learning. EMS teachers should be able to teach all three disciplines within the EMS effectively. There is also a need for teacher training and development. Teachers should use a variety of teaching strategies and should adapt their teaching practice as a result of curriculum change. Accounting within the EMS should be a stand-alone subject.

OPTIMAL SPEED PLANNING TO MINIMIZE ENERGY USE OF AUTONOMOUS BATTERY ELECTRIC AND FUEL CELL HYBRID ELECTRIC VEHICLES

Meshginqalam, Ata January 2022 (has links)
Electric vehicles with autonomous driving are the future of transportation, as they are sustainable, efficient, environmentally friendly, and can provide collision-free congestion-free driving. However, the sensing and control technology adds new accessory loads which increase the vehicle energy use. Thus, it is critical to minimize energy use where possible, and optimal speed planning is a promising way to achieve this goal and is thus the topic of study for this thesis. First, a low-computation framework for the onboard calculation of energy-optimal cruising speed of battery electric vehicles is proposed. The framework is used to investigate the critical parameters for energy-optimal cruising speed determination, and it includes major internal and external vehicle losses, uses accurate motor-inverter efficiency maps as look-up tables, and does not require knowledge of the future route. This framework is validated using three electric vehicle models in MATLAB/SIMULINK. Secondly, a novel two-level model predictive control (MPC) speed control algorithm for battery electric autonomous vehicles as a successive convex optimization problem is proposed. The proposed successive convex approach produces a highly accurate optimal speed profile while also being solvable in real-time with the vehicle's onboard computing resources. This algorithm is used to perform a variety of simulated test cases, which show an energy savings potential of about 1% to 20% for different driving conditions, compared to a non-energy-optimal driving profile. Lastly, the research is expanded to consider fuel cell hybrid electric vehicles (FCHEVs), which have the added need for an optimal energy management strategy inv addition to optimal speed planning. Novel successive and integrated convex speed planning and energy management algorithms are proposed to solve the minimum hydrogen consumption problem for autonomous FCHEVs. The simulation results show that the proposed integrated method, which considers fuel cell system efficiency in the optimization objective function for speed planning, leads to 0.19% to 2.37% less hydrogen consumption compared to the successive method on short drive cycles with varying accessory loads. On the same test cycles, the integrated method uses 10.12% to 21.62% less hydrogen than an arbitrary constant-speed profile. / Thesis / Doctor of Philosophy (PhD) / Autonomous vehicles are expected to be the future of transportation, however, the high continuous electrical accessory power needed for control and perception is a challenge. Fortunately, there is an inherent property of speed planning for autonomous vehicles that can help deal with this problem. This thesis focuses on optimal speed planning to minimize energy use, proposing convex methods considering detailed internal and external losses for battery electric vehicles (BEVs), and optimal speed planning integrated with optimal energy management for fuel cell hybrid electric vehicles (FCHEVs). The proposed framework in this thesis is accurate while maintaining a low computational effort, which are the desired criteria for real-time algorithms.

Identification et validation fonctionnelle de gènes candidats contrôlant la composition de la cuticule chez le fruit de tomate / Identification and functional validation of candidate genes controlling the composition of the tomato fruit cuticle

Petit, Johann 17 December 2013 (has links)
La cuticule, une matrice lipidique extracellulaire constituée de cires et d’un squelette de cutine, est la barrière de défense la plus externe des plantes face à leur environnement. Elle intervient dans de nombreuses propriétés agronomiques comme la conservation post récolte, les propriétés mécaniques ou bien l’aspect du fruit, dont la brillance. Afin d’isoler des mutants de cuticule, le criblage d’une collection de mutants EMS de tomate a été entrepris, en se basant sur la brillance des fruits, conduisant à la sélection de 24 mutants. Chez ceux-ci, des analyses biochimiques ont montré de fortes variations de charge et de composition de la cuticule, notamment chez les mutants de cutine. La caractérisation de 4 mutants remarquables a été entreprise afin d’identifier les mutations responsables des phénotypes de brillance. Le mutant le plus affecté, présentant une charge en cutine réduite de 85% par rapport au type sauvage, a révélé une mutation du gène SlGDSL2 codant pour une acylhydrolase à motif GDSL, responsable de la polymérisation de la cutine. Afin d’étudier la formation et la régulation de la cutine, la suite du travail a consisté à obtenir et à caractériser des simples et des doubles mutants affectés dans la synthèse des monomères de cutine, le transport apoplastique et la polymérisation de la cutine. / The cuticle, an extracellular lipid matrix consisting of waxes and of a cutin skeleton is the outermost plants protection barrier against their environment. The cuticle is involved in many agronomic traits such as post-harvest storage, biomechanical or fruit appearance properties like surface brightness. In order to isolate cuticle mutants, the screening of an EMS tomato mutants collection has been undertaken, based on fruit brightness, leading to the selection of 24 mutants. Biochemical analyzes have shown wide variations in cuticle loads and compositions, especially in cutin mutants. The characterization of 4 remarkable mutants was undertaken to identify the mutations responsible for brightness phenotypes. The most affected mutant shows a cutin load reduced by 85% compared to the wild type, and is due to a mutation in the SlGDSL2 gene, encoding a GDSL-motive acylhydrolase enzyme, responsible for the cutin polymerization. In order to further study the cutin formation and regulation, the next work was to obtain and characterize single and double mutants affected in cutin monomer synthesis, apoplastic transport and cutin polymerization.

Optimisation d'un électromyostimulateur intelligent pour le reconditionnement musculaire / Optimization of an intelligent electromyostimulator for the muscular rehabilitation

Maillard, Aurore 18 December 2017 (has links)
L’électrostimulation (EMS) est l’envoi d’impulsion électrique par le biais d’électrodes. Ces électrodes de surface sont posées sur la zone musculaire à stimuler. Cette technique est de plus en plus utilisée dans la rééducation musculaire lors de blessures, de pertes de mouvement ou d’atrophie. Ces EMS sont généralement combinées avec l’électromyogramme (EMG) qui enregistre l’activité électrique du muscle. Le but de la thèse est d’optimiser les paramètres de stimulation en temps réel lors d’une EMS. Pour ce faire, de nouvelles stratégies de contrôle robustes sont à développer. Nous avons convenu durant la thèse de travailler sur un modèle spécifique. / This project aims to optimize smart electromyostimulators for the muscular reeducation. The electrostimulator optimization aims to improve the electrostimulation sessions (EMS) by obtaining informations on the muscular electical stimulations and the control application in real time in order to control the muscular response. Various control methods of the muscular force are been developed and applied on an accurate model. In first, the techniques will be applied on the partial model without taking into account the muscular fatigue then in second in taking into account the presence of fatigue and its effects. Theses control methods act on the stimulation parameters in frequency and in amplitude in function of the muscular response.

Implementace environmentálního manažerského systému v podniku

Dobešová, Martina January 2019 (has links)
This diploma thesis elaborates a proposal of an environmental management system implementation according to the ČSN EN ISO 14001:2016 standard in a selected company in Brno. Based on own activities in the company and in-depth interviews with the employees, the current situation and field of business of the company and its experience with the implementation of certifications were described. Furthermore, the company’s approach to environmental issues, including the definition of environmental aspects of the company, was identified. According to the individual chapters of the international standard, the thesis suggests steps to obtain the ISO certification. Furthermore, the thesis presents possible benefits and costs related to EMS implementation. The results of the interviews show whether the company has the necessary capacity to implement the standard and whether the certification is relevant for the company. Regardless of the suitability of the EMS for the company, appropriate measures to the environmental performance improvement are designed.
