Dunn, Samuel James. "Reconceiving a Necessary Evil: Teaching a Transferable FYC Research Paper." BYU ScholarsArchive, 2013. https://scholarsarchive.byu.edu/etd/3633.
Full textAbstract:
The place of the research paper in first-year composition (FYC) courses is often debated in composition forums. Many argue that the a-disciplinary nature of FYC doesn't allow instructors to teach the research paper in a way that will be transferable to disciplinary writing tasks, while others say that it is possible, as long as we have a thorough understanding of the kinds of writing tasks students will face in the disciplines and specifically teach writing skills that will be transferable. To identify these more generalizable writing skills to be emphasized, I interviewed 14 professors at Brigham Young University from different disciplines about the research papers they teach within their upper-division disciplinary courses and the kinds of researching and writing skills they expect students to have mastered before enrolling in these courses. I collated the results of the interviews and categorized 22 skills into four categories: writing process knowledge, genre knowledge, rhetorical knowledge, and researching knowledge, finding correlation between the 22 skills I identified with skills identified by both John Bean and Carra Leah Hood, lending credence to the value of my identified skills as worthwhile to be focused on in FYC. I draw on Amy Devitt's idea that the school genres we teach in FYC are antecedent genres to assert that teaching a research paper in FYC outside of the constraints of any one discipline can provide a viable and valuable learning experience, provided that it is taught with an emphasis on these writing skills that are most valued across the disciplines, and provided it is taught as a step along the way to later mastery of disciplinary genres.

Full textAbstract:
This study traces the transfer of writing-related knowledge and concepts from the composition classroom into the writing assignments composed by students within the same course. Working in a first-year-composition classroom taught through a writing-about-writing curriculum, the researcher observed students as they navigated from the initial learning of concepts such as rhetorical situations, writing processes, and discourse communities, into an application of these concepts in various writing assignments, including rhetorical analyses and discourse community profiles. By analyzing a composition instructor's objectives for her assignments and observing the interaction between students and their instructor in a single composition course for the duration of one semester, the researcher traced how students operationalized knowledge from the classroom and applied it in their own writing. After tracing this operalization through interviews with the instructor, observation of class activities and analysis of assignment sheets and student papers, the researcher proposes that instructors may encourage transfer within their composition classrooms by adequately presenting assignment objectives to students, and by allowing sufficient scaffolding of writing tasks. In this way, the researcher explains that students may be able to understand the objectives of their writing assignments in a way that may encourage them to apply the knowledge they learned in the classroom to the writing tasks assigned by their instructor.ID: 029809951; System requirements: World Wide Web browser and PDF reader.; Mode of access: World Wide Web.; Thesis (M.A.)--University of Central Florida, 2011.; Includes bibliographical references (p. 76-77).

Full textAbstract:
With respect to matters of identities as a treacherous and sensitive subject in today’s college classroom, this project explores concepts like identity, otherness, resistance, otherization, writer’s identity, and identity negotiation; and interrogates how these concepts may affect learning and professional relationship among the class members in the First Year Composition Classroom. The crux of the argument in this research is that process and social construction collaborative pedagogies can be effective in negotiating the resistance and otherness manifesting from identity dichotomies in the First Year Composition classroom.

Full textAbstract:
Online education has received excessive attention in recent decades as its characteristics and potential have undergone intense debate and scrutiny. Similar debate and scrutiny surround the content of first-year composition (FYC) courses. As we continue to define what composition studies entails, we redefine what we study in FYC. Yet discussions of blended delivery mode---using both online and on-ground teaching methods---get lost amid these debates. This dissertation addresses the dearth of research on blended online writing instruction by asserting the essential nature of connections between the content and the delivery of FYC courses.
Through case studies of two experienced instructors teaching FYC in a blended environment for the first time, this dissertation evaluates the composition--both as a noun and as a verb—of FYC courses in light of the technology involved. Through an analysis of interviews with instructors, students, and faculty involved with FYC, I highlight the points of contact--the interfaces—that themselves create the experience of a class. This analysis applies interface theory from rhetoric and composition to the pedagogical acts of teaching FYC and reveals how attention to classroom interfaces can benefit our pedagogy.
This project also incorporates student performance data (in the form of portfolio evaluations), student perception data (in the form of surveys), and comparative institutional data (in the form of website analysis) to better understand the varied causes, effects, and implementations of blended learning. By looking outside the classroom environment, I show how schools influence the way blended courses are perceived by those who create them. The differences in student and instructor expectations for this kind of class emerged as particularly influential in determining how successful a blended course can be.
The perspective taken by an instructor in terms of experience and expertise also emerged as a significant determinant of perceived success, particularly for instructors themselves. This dissertation reveals the delicate balance instructors must navigate between relying on expertise in the field and exploring the course delivery as a novice. This balance allows instructors to be responsive, flexible, and dynamic in their classes while also assisting students in their efforts to better understand FYC course content.
Overall, this dissertation defines and advocates for a hybrid approach to FYC instruction as an essential evolution of our pedagogical praxis. Students lead increasingly hybrid lives and learn in increasingly hybrid ways. Instructors must adopt hybridity in their classes to accommodate not only students' changing learning styles but also the changing nature of composition as a field and writing as its subject matter. And finally, institutions must consistently define and implement principles of hybridity to help reduce confusion and frustration across the disciplines. Suggestions for educators and institutions alike are provided to help meet the needs of today's students.Ph.D.

Full textAbstract:
As writing about writing (WAW) research enters its "second wave," characterized not only by an increase in data-driven studies that theorize and assess the effectiveness of WAW curricula (Downs) but also by an increase in its prominence and adaptation, particularly among emerging writing studies scholars and teachers (e.g., Bird et al.), a space has opened for more and varied types of research, especially empirical research, to determine its effectiveness and to produce more solid recommendations for training and curriculum development, especially for those who are new to the field. This case study, which highlights how a novice teacher responds to a new teaching experience, aims to address the dearth of empirical research on WAW curricula and to aid other graduate instructors interested in teaching WAW or program administrators interested in implementing WAW. The study reports results from data collected (e.g., interviews, in-class observations, teachings logs) on the experience of a second-year MA graduate student in composition and rhetoric as he taught a WAW-based curriculum in a first-year composition (FYC) class in the beginning of 2016. His twenty students were also research subjects, but only a small portion of their data is reported here. The instructor's experience, chronicled in narrative form, began optimistically, though with a hint of skepticism, and ended in discouragement and even pessimism. These results were largely unexpected due to the instructor's confidence with and knowledge of WAW history, assumptions, and pedagogy and experience teaching FYC. However, his struggle with the approach reveals and confirms several important points for anyone hoping to teach or implement WAW. Particularly, new WAW instructors need sustained training, support, and mentoring to help them properly temper their expectations for the course, correctly and usefully interpret their experiences teaching WAW, successfully transfer prior teaching knowledge and methods to the WAW classroom, and ultimately find their place in WAW instruction.

Lúpus Eritematoso Sistêmico (LES) é uma doença autoimune que afeta diversos órgãos e sistemas. Embora os fatores que contribuem para a patogenia da doença não estejam completamente esclarecidos, sabe-se que o LES é um distúrbio multifatorial com influência de fatores genéticos e ambientais e com o envolvimento de células B e T autorreativas contra uma variedade de componentes celulares. Sabendo-se que o gene FYB (Proteína Ligante de Fyn) codifica uma proteína adaptadora que participa da cascata de ativação dos linfócitos T e que uma desordem nesse processo pode influenciar o desenvolvimento da autoimunidade, esse gene foi considerado candidato à susceptibilidade ao LES. Em um estudo anterior realizado pelo nosso grupo, foi observada a associação dos TagSNPs rs6863066 e rs358501, localizados nas regiões 5’UTR e 3’UTR do gene respectivamente, com a susceptibilidade ao LES em uma população de Ribeirão Preto/SP. Uma vez que TagSNPs representam outros SNPs que se encontram em desequilíbrio de ligação, o presente estudo analisou possíveis associações entre o desenvolvimento do LES e SNPs representados pelos TagSNPs rs6863066 e rs358501 na mesma população. Para confirmarmos a associação do desenvolvimento do LES com os TagSNPs rs6863066 e rs358501 e outros TagSNPs, também foi realizado um estudo de replica na população de Pernambuco. Para isso, sequenciamos a região promotora e parte das regiões 5’UTR e 3’UTR do gene FYB no grupo de Ribeirão Preto/SP e genotipamos 7 TagSNPs no grupo amostral de Pernambuco. O grupo de estudo foi composto por 143 pacientes e 184 controles de Ribeirão Preto/SP; e 116 pacientes e 162 controles de Pernambuco. Na população de Ribeirão Preto/SP, além da confirmação da associação com os SNPs rs6863066 e rs358501, também foi observada a associação do SNP rs13188259 G>A no promotor do gene FYB com o desenvolvimento do LES: tanto a presença do alelo A (OR = 1,77, CI = 1,27 – 2,47, p = 0,001), como dos genótipos A/A (OR = 2,6, CI = 1,19 – 5,64, p = 0,003) e G/A (OR = 2,2, CI = 1,37 – 3,52, p = 0,001) mostraram conferir risco ao desenvolvimento do LES. Na população de Pernambuco, nenhuma associação com a susceptibilidade foi observada, entretanto foi encontrada a associação entre o alelo T (OR = 3,5, CI = 1,13 – 10,83, p = 0,02) e o genótipo T/T (OR = 11,8, CI = 1,1 – 123,3, p = 0,01) do SNP rs6863066 C>T e do alelo G (OR = 3,9, CI = 1,26 – 12,03, p = 0,01) e genótipo G/G (OR = 8,15, CI = 1,3 – 49,5, p = 0,002) do SNP rs2161612 A>G com a ocorrência da Síndrome Antifosfolipídeo. Também foram observadas a associação entre o alelo G (OR = 2,4, CI = 1,28 – 4,6, p = 0,005) e o genótipo G/G (OR = 5,22, CI = 1,6 – 17,6, p = 0,004) do SNP rs2161612 A>G e o desenvolvimento da serosite e a associação entre o alelo A (OR = 4,4, CI = 1,22 – 15,96, p = 0,01) e o genótipo G/A (OR = 4,89, CI = 1,3 – 18,6, p = 0,01) do SNP rs1642515 G>A, o alelo T (OR = 2,14, CI = 1,1 – 4,2, p = 0,03) e o genótipo T/T (OR = 5,3, CI = 1,42 – 19,8, p = 0,006) do SNP rs404122 A>T e o alelo C (OR = 2,4, CI = 1,2 – 4,9, p = 0,01) e o genótipo C/C (OR = 8,6, CI = 1,8 – 40,9, p = 0,002) do SNP rs358501 T>C com a ocorrência de úlceras nos pacientes com LES. Esses resultados sugerem um possível envolvimento do gene FYB no desenvolvimento do LES e suas manifestações clínicas e laboratoriais, contribuindo para uma maior compreensão da patogênese do LES.

Resumo: Os antígenos eritrocitários são estruturas polimórficas correspondendo glicoproteínas ou glicolípides localizados na membrana eritrocitária. Os antígenos Fya e Fyb são os mais importantes do sistema Duffy e carreados por glicoproteínas de múltipla passagem transmembrana. Os antígenos S e s, pertencentes ao sistema MNS, são carreados pela glicoforina B (GPB). Há relatos na literatura de que todos eles seriam sensíveis à ação enzimática leucocitária e assim podem apresentar alteração de expressão durante o armazenamento. O nosso objetivo foi estudar a influência da remoção de leucócitos e do tempo de armazenamento na expressão dos antígenos Fya, Fyb, S e s em concentrados de hemácias (CH) coletados com CPDA-1 e armazenados para fins transfusionais e produção de reagentes eritrocitários. Estudamos 49 unidades de CH. Elas foram subdivididas em duas bolsas logo após a coleta sem abertura do sistema e uma foi leucodepletada com filtros SepacellTM antes do armazenamento. A outra foi utilizada como controle. Foi realizada avaliação dos antígenos nos dias 1 e 35 de armazenamento através da hemaglutinação em tubo, aglutinação em gel e imunofenotipagem por citometria de fluxo. Foi utilizado o QIFIKITTM para determinar o número de sítios antigênicos através da citometria de fluxo. O antígeno Fya apresentou um aumento na intensidade de fluorescência (p=0,02) apenas no dia 35 de armazenamento quando a bolsa foi leucodepletada antes do armazenamento. Os outros antígenos (Fyb, S e s) não apresentaram diferença de expressão com a leucodepleção. Em relação ao tempo de armazenamento, não detectamos alteração significativa na densidade dos antígenos Fya, Fyb, S e s durante os 35 dias estudados. O resultado do número de sítios estimados através da citometria de fluxo para os respectivos antígenos foi: Fya 1,1 e 2,3 x 104 em doadores Fy(a+b+) e Fy(a+b-) respectivamente; Fyb 0,72 e 0,78 x 104 em doadores Fy(a+b+) e Fy(a-b+); S 1,0 e 2,1 x 104 em indivíduos Ss e SS e para o antígeno s 1,0 e 2,4 x 105 em doadores Ss e ss. A citometria de fluxo demonstrou ser uma técnica sensível e capaz de detectar alterações não perceptíveis com os outros métodos. Foi mais reprodutível, estável e adequada para os antígenos Fya e Fyb que para os antígenos S e s. Isto talvez seja devido às características dos soros anti-S e anti-s disponíveis comercialmente. O estudo da expressão durante o armazenamento e a estimativa do número de sítios antigênicos são importantes no controle de qualidade e validade dos reagentes eritrocitários utilizados na prática transfusional. A leucodepleção influenciou somente o antígeno Fya no dia 35 de armazenamento

Simbassängen i Folkhälsocentrum i Laholm har drabbats av skador. Läckage i skvalprännorna har orsakat problem i de övriga konstruktionsdelarna. Laholmskommun har år 2002 vidtagit akuta åtgärder i hopp om att stoppa läckage och förebygga ännu större skador. Reparationsarbetet utfördes och efter två år konstaterades fortsatt läckage.För att kunna bedömma skadornas omfattning och orsak utförs en tillståndsbedömning av befintlig konstruktion. Tillståndsbedömningen kommer att ligga till grund för val av reparationsmetoder och reparationsomfattning. Det största problemet är armeringskorrosion föranled av karbonatisering och kloridinträngning. Hela konstruktionen befinner sig i en väldigt aggressiv miljö som accelererar hela nedbrytningsprocessen. Genom att göra okulärbesiktning och laboratorieanalys har jag kommit fram till att skadorna är omfattande och reparationsarbeten kommer att vara därefter.

This thesis work was made to optimize the writing of the construction specifications at FKA. These construction specifications are created before each plant modifications that is started because requirements from the Swedish radiation safety authority (SSM) and internally on Forsmarks nuclear group as constructions / implementation documentation The study was done through seven interviews of two people at three different groups involved in the construction specification and an interview from the group accredited verification. The four selected groups were selected through an extensive analytical work resulted in an elimination matrix where these four groups was considered to be most involved with the construction specification. The questions asked to these individuals were based on the instructions and sample text that are described in the construction specification. To ensure the quality of the thesis were to limit itself to the chapters that were considered most relevant to improve. The analysis revealed a number of points that should be improved, partly into the routines when writing the construction specification and when ether sample text or suggestions should be changed and complemented. Some of the most interesting results where that there are some relatively simple improvements that can be implemented with a small amount of work. Some of those results where an implementation of a table for the radiation in a specific room as well as using an excel file where all people involved in the construction specification can make suggestions for the updated version of the operating instructions. Other improvements are more complicated to implement as they are soft issues like a continuous improvement of the communication between different groups at FKA

Full textAbstract:
Fluidised cracking catalysts, which contain a form of zeolite-Y as the main catalytically active component, are widply used commercially for the conversion of crude oil into more profitable product streams. During the cracking reaction, these catalysts are contaminated with vanadium which has a marked effect on the crystallinity of the zeolite-Y component and, as a consequence, activity and selectivity for hydrocarbon processing is degraded. The purpose of this work has been to carry out a detailed investigation, on the laboratory scale, of the effect of vanadium contaminatioil on both commercial and model rare earth ion-exchanged zeolite-Y catalysts. Vanadium contamination was achieved using a standard (Mitchell) method and catalysts were subject to treatment conditions similar to those found in the regenerator part of a fluidised catalytic cracking unit using a specially constructed furnace. Investigations of the solid state chemical reactions between vanadium and rare earth compounds, both in the presence and absence of silica and alumina support materials typical of those found in commercial catalysts, extend the study. Extensive use is made of magic-angle-spinning nuclear magnetic resonance spectroscopy (5 IV and 27AI), X-ray powder diffraction and surface area measurements for sample characterisation. The apparatus for surface area measurements was constructed during the course of the work. It is suggested that the reduction in crystallinity of rare earth ion-exchanged zeolite-Y in the presence of vanadium is associated with the removal of rare earth ions from the cage structure of the zeolite. The extent of this process depends upon the details of the treatment conditions and important factors are identified. The observation of the formation of LaV04 in a range of hydrothermally treated lanthanum ion-exchanged zeolite-Y samples supports the proposed model.

Neste trabalho é analisada a Agência Nacional de Telecomunicação (Anatel) enquanto o novo órgão regulador das telecomunicações no Brasil. Com vistas a isso foi feita uma revisão bibliográfica que culmina com o estudo da reestruturação estatal, a discussão de conceitos tais como regulação, desregulamentação, re-regulação e regulamentação, além de um olhar político, jurídico e histórico do setor no Brasil. É feito também um exame do Conselho Diretor e Consultivo da Agência. Além disso, foram realizadas entrevistas com principais agentes e instituições que circundam e atravessam o setor, tais como os representantes da Anatel, de empresas prestadora de serviços de telecomunicações e de diretores de entidades de classe, ligadas aos trabalhadores. Os problemas e questões enfrentados neste trabalho, diz respeito sobre qual a função e, em razão disso, qual é a eficácia da Anatel enquanto agencia reguladora dos serviços de telecomunicações no Brasil. Relacionado a isto, questionamos sobre os principais agentes definidores das políticas implementadas no setor de telecomunicações no Brasil. Que relação existe de fato entre a Anatel e o Poder Executivo Nacional. Além de qual a condição da Ouvidoria na esfera administrativa da Anatel? Em que se constitui o poder do Conselho Consultivo no interior decisório da Anatel? Qual o papel do mercado na maneira como se dá a regulação das telecomunicações no Brasil, hoje? Como os diversos agentes do setor de telecomunicações verificam a eficácia da Anatel? Nas considerações finais, os essas questões foram retomadas, amparadas nas discussões realizadas no corpo da dissertação, concluindo, assim que, as políticas de telecomunicações são ditadas pelo mercado, o Conselho Diretor é o principal órgão de poder dentro da Anatel e o Conselho Consultivo dispõe de pouco poder de influência nas decisões tomadas pela Anatel.

Previous issue date: 2012-01-23La parte literaria de este trabajo retrata per?odos de la vida de un hombre desde la adolescencia hasta la vejez. El hilo conductor de la historia es su relaci?n con una amiga de infancia, donde sus expectativas y decepciones se mezclan. En los ensayos te?ricos a continuaci?n (a) explicito mi protelo de creaci?n y las influencias literarias m?s importantes durante el per?odo de escrita; (b) investigo los conceptos de imaginaci?n, ficci?n y realidad y su modo de relacionamiento. En el sentido com?n, generalmente entendemos que ficci?n y realidad son conceptos contrarios, siendo el uno el substrato de la negaci?n del otro. ?Pero ser? verdad? Para fundamentar esta reflexi?n, utilizo los te?ricos H. Vaihinger y W. Iser. El primero pr?cticamente empez? las reflexiones acerca del concepto de ficci?n en el sentido de entender la ficci?n como parte de Ia realidad, a saber, muchas de nuestras ideas m?s b?sicas y caras pueden ser comprendidas como ficciones. Iser por su vez, desarrollando las ideas de Vaihinger, piensa como esta polaridad ficci?n vs. realidad deber?a ser comprendida como un juego entre el ficcional, el real y el imaginario, cancelando la polaridad, y por consecuencia, lugares transcendentales desde donde estamos acostumbrados a posicionarnos; (c) intento pensar como el amor, sentimiento subyacente a la relaci?n de los personajes, puede funcionar como un generador de ficciones; Para concluir, (d) hay un ensayo final que intenta retomar las cuestiones esenciales presentes en los ensayos previos.

According to reliable statistics, electrical fire ignition sources have a notable impact regarding the generation of fires and explosions. Electrical equipment and installations can also be the victims of fire. This is due to the wearing of insulation, the reduction of dielectric strength of the air and other factors. This combination opens up a space for a wide range of experimental and educational research which until now has seen little development. The state of the art of electrical fire is introduced illustrating it with electro technical laboratory experiments as well as with real story cases.
The electric arc which produces the ejection of hot particles is one of the electrical fire ignition sources, has seen little investigation. The development of experiments can help in finding out more about this phenomenon. A case study by the fire department of Catalonia can be used as an explanation, which suggests that there is a direct relationship between ventilation and air conditioning ducts made of aluminum and electrical ignition.
The phenomenon electrical breakdown in gases has a special characteristic in the presence of fire. It has an effect on electricity supply, fire extinguisher security, fire investigations and the fire spread. This has brought about experiments to illustrate the point. The experiments are related with the behavior of high voltage power lines in presence of fire in our environmentLes fonts d’ignició d’origen elèctric tenen una incidència estadística notable en relació amb la generació d’incendis i explosions. Els equips i instal·lacions elèctriques també són víctimes del foc. És a causa de la destrucció dels aïllaments i la disminució de la rigidesa dielèctrica de l’aire, entre d’altres factors. Aquest conjunt dóna lloc a un espai de recerca experimental i docència ampli, que encara es troba poc desenvolupat. S’introdueix l’estat de l’art il·lustrant-lo amb experiments de laboratori electrotècnic i l’exposició de casos reals. El curtcircuit amb arc elèctric que produeix l’ejecció de partícules calentes, és una de les fonts d’ignició elèctrica poc investigades. Es desenvolupen experiments que poden ajudar a estudiar i il·lustrar aquest fenomen. S’utilitza un cas aportat pels Bombers de la Generalitat de Catalunya com a fil conductor. Suggeria una relació entre les canalitzacions de ventilació i climatització fabricades amb alumini i la ignició elèctrica. Els fenòmens de descàrrega elèctrica en gasos tenen unes característiques particulars en presència de foc.Té implicacions en el subministrament d’energia elèctrica, la seguretat dels equips d’extinció d’incendis, la investigació de sinistres i la propagació del foc. Es porten a terme experiments que contribueixen a il·lustrar-ho. Es relacionen amb el comportament de les línies aèries d’alta tensió en presència de foc en el nostre entorn.

Full textAbstract:
The modeling and evaluation calculus FMC-QE, the Fundamental Modeling Concepts for Quanti-tative Evaluation [1], extends the Fundamental Modeling Concepts (FMC) for performance modeling and prediction. In this new methodology, the hierarchical service requests are in the main focus, because they are the origin of every service provisioning process. Similar to physics, these service requests are a tuple of value and unit, which enables hierarchical service request transformations at the hierarchical borders and therefore the hierarchical modeling. Through reducing the model complexity of the models by decomposing the system in different hierarchical views, the distinction between operational and control states and the calculation of the performance values on the assumption of the steady state, FMC-QE has a scalable applica-bility on complex systems.
According to FMC, the system is modeled in a 3-dimensional hierarchical representation space, where system performance parameters are described in three arbitrarily fine-grained hierarchi-cal bipartite diagrams. The hierarchical service request structures are modeled in Entity Relationship Diagrams. The static server structures, divided into logical and real servers, are de-scribed as Block Diagrams. The dynamic behavior and the control structures are specified as Petri Nets, more precisely Colored Time Augmented Petri Nets. From the structures and pa-rameters of the performance model, a hierarchical set of equations is derived. The calculation of the performance values is done on the assumption of stationary processes and is based on fundamental laws of the performance analysis: Little's Law and the Forced Traffic Flow Law. Little's Law is used within the different hierarchical levels (horizontal) and the Forced Traffic Flow Law is the key to the dependencies among the hierarchical levels (vertical). This calculation is suitable for complex models and allows a fast (re-)calculation of different performance scenarios in order to support development and configuration decisions.
Within the Research Group Zorn at the Hasso Plattner Institute, the work is embedded in a broader research in the development of FMC-QE. While this work is concentrated on the theoretical background, description and definition of the methodology as well as the extension and validation of the applicability, other topics are in the development of an FMC-QE modeling and evaluation tool and the usage of FMC-QE in the design of an adaptive transport layer in order to fulfill Quality of Service and Service Level Agreements in volatile service based environments.
This thesis contains a state-of-the-art, the description of FMC-QE as well as extensions of FMC-QE in representative general models and case studies. In the state-of-the-art part of the thesis in chapter 2, an overview on existing Queueing Theory and Time Augmented Petri Net models and other quantitative modeling and evaluation languages and methodologies is given. Also other hierarchical quantitative modeling frameworks will be considered. The description of FMC-QE in chapter 3 consists of a summary of the foundations of FMC-QE, basic definitions, the graphical notations, the FMC-QE Calculus and the modeling of open queueing networks as an introductory example. The extensions of FMC-QE in chapter 4 consist of the integration of the summation method in order to support the handling of closed networks and the modeling of multiclass and semaphore scenarios. Furthermore, FMC-QE is compared to other performance modeling and evaluation approaches. In the case study part in chapter 5, proof-of-concept examples, like the modeling of a service based search portal, a service based SAP NetWeaver application and the Axis2 Web service framework will be provided. Finally, conclusions are given by a summary of contributions and an outlook on future work in chapter 6.

ISBN 1-60132-029-9.FMC-QE (Fundamental Modeling Concepts for Quantitative Evaluation [1]) ist eine auf FMC, den Fundamental Modeling Concepts, basierende Methodik zur Modellierung des Leistungsverhaltens von Systemen mit einem dazugehörenden Kalkül zur Erstellung von Leistungsvorhersagen wie Antwortzeiten und Durchsatz. In dieser neuen Methodik steht die Modellierung der hierarchischen Bedienanforderungen im Mittelpunkt, da sie der Ursprung aller dienstbasierenden Systeme sind. Wie in der Physik sind in FMC-QE die Bedienanforderungen Tupel aus Wert und Einheit, um Auftragstransformationen an Hierarchiegrenzen zu ermöglichen. Da die Komplexität durch eine Dekomposition in mehreren Sichten und in verschiedene hierarchische Schichten, die Unterscheidung von Operations- und Kontrollzuständen, sowie dazugehörige Berechungen unter Annahme der Stationarität reduziert wird, skaliert die Anwendbarkeit von FMC-QE auf komplexe Systeme. Gemäß FMC wird das zu modellierende System in einem 3-dimensionalen hierarchischen Beschreibungsraum dargestellt. Die quantitativen Kenngrößen der Systeme werden in drei beliebig frei-granularen hierarchischen bi-partiten Graphen beschrieben. Die hierarchische Struktur der Bedienanforderungen wird in Entity Relationship Diagrammen beschrieben. Die statischen Bedienerstrukturen, unterteilt in logische und reale Bediener, sind in Aufbaudiagrammen erläutert. Außerdem werden Petri Netze, genauer Farbige Zeit-behaftete Petri Netze, dazu verwendet, die dynamischen Abläufe, sowie die Kontrollflüsse im System zu beschreiben. Anschließend wird eine Menge von hierarchischen Gleichungen von der Struktur und den Parametern des Modells abgeleitet. Diese Gleichungen, die auf dem stationären Zustand des Systems beruhen, basieren auf den beiden Fundamental Gesetzen der Leistungsanalyse, dem Gesetz von Little und dem Verkehrsflussgesetz. Das Gesetz von Little definiert hierbei Beziehungen innerhalb einer hierarchischen Schicht (horizontal) und das Verkehrsflussgesetz wiederum Beziehungen zwischen hierarchischen Schichten (vertikal). Die Berechungen erlauben Leistungsvorhersagen für komplexe Systeme durch eine effiziente Berechnung von Leistungsgrößen für eine große Auswahl von System- und Lastkonfigurationen. Innerhalb der Forschungsgruppe von Prof. Dr.-Ing Werner Zorn am Hasso Plattner Institut an der Universität Potsdam ist die vorliegende Arbeit in einen größeren Forschungskontext im Bereich FMC-QE eingebettet. Während hier ein Fokus auf dem theoretischen Hintergrund, der Beschreibung und der Definition der Methodik als auch der Anwendbarkeit und Erweiterung gelegt wurde, sind andere Arbeiten auf dem Gebiet der Entwicklung einer Anwendung zur Modellierung und Evaluierung von Systemen mit FMC-QE bzw. der Verwendung von FMC-QE zur Entwicklung einer adaptiven Transportschicht zur Einhaltung von Dienstgüten (Quality of Service) und Dienstvereinbarungen (Service Level Agreements) in volatilen dienstbasierten Systemen beheimatet. Diese Arbeit umfasst einen Einblick in den Stand der Technik, die Beschreibung von FMC-QE sowie die Weiterentwicklung von FMC-QE in repräsentativen allgemeinen Modellen und Fallstudien. Das Kapitel 2: Stand der Technik gibt einen Überblick über die Warteschlangentheorie, Zeit-behaftete Petri Netze, weitere Leistungsbeschreibungs- und Leistungsvorhersagungstechniken sowie die Verwendung von Hierarchien in Leistungsbeschreibungstechniken. Die Beschreibung von FMC-QE in Kapitel 3 enthält die Erläuterung der Grundlagen von FMC-QE, die Beschreibung einiger Grundannahmen, der graphischen Notation, dem mathematischen Modell und einem erläuternden Beispiel. In Kapitel 4: Erweiterungen von FMC-QE wird die Behandlung weiterer allgemeiner Modelle, wie die Modellklasse von geschlossenen Netzen, Synchronisierung und Mehrklassen-Modelle beschrieben. Außerdem wird FMC-QE mit dem Stand der Technik verglichen. In Kapitel 5 werden Machbarkeitsstudien beschrieben. Schließlich werden in Kapitel 6 eine Zusammenfassung und ein Ausblick gegeben.

Full textAbstract:
In the field of software engineering, software architecture plays an important role particularly in areas of critical and large-scale software system development and over the years it has evolved as an important sub-discipline within the field of software engineering. However, software architecture is still an emerging discipline mainly attributed by the lack of standardized way for architectural representation and also due to lack of analysis methods that can determine if the intended architecture translates into correct implementation during the software development [HNS00]. Architecture compliance checking [KP07] is a technique used to resolve latter part of the problem and Fraunhofer SAVE (Software Architecture Visualization and Evaluation) is a compliance-checking tool that uses fact extraction. This master’s thesis provides fact extraction support to Fraunhofer SAVE for a system developed using Ruby on Rail framework by developing a fact extractor. The fact extractor was developed as an eclipse plug-in in Java that was integrated with SAVE platform, it consists of a parser that parses Ruby source code and then generates an abstract syntax tree. The architectural facts are extracted by analyzing these abstract syntax trees using a visitor pattern from which architecture of the system are generated. It is represented using the internal model of the SAVE platform. The fact extractor was validated using two reference systems of differing sizes developed using Ruby on Rails framework. A reference system with smaller size, which contains all the relevant Ruby language constructs, was used to evaluate correctness and completeness of the fact extractor. The evaluation result showed the correctness value of 1.0 or 100% and completeness value of 1.0 or 100%. Afterwards, a larger application with more complex architecture was used to validate the performance and robustness of the fact extractor. It has successfully extracted, analyzed and build the SAVE model of this large system by taking 0.05 seconds per component without crashing. Based these computations, it was concluded that the performance of the fact extractor was acceptable as it performed better than C# fact extractor.

Full textAbstract:
Irradiation induced void swelling is problematic for the application of austenitic steels under high dose irradiation. In this thesis, the swelling is characterized by dislocation bias. The dislocation bias is obtained using the finite element method, accounting for fcc copper and nickel under electron irradiation. The methodology is implemented with the interaction energies between an edge dislocation and point defects. Analytically derived interaction energies, which are based on elasticity theory, are compared with interaction energies obtained from atomistic model using semi-empirical atomic potentials as physics basis. The comparison shows that the description of analytical interaction energies is inaccurate in the dislocation core regions. The bias factor dependence on dislocation density and temperature is presented and discussed. At high temperatures or low dislocation densities, the two approaches tend to converge. However, the dislocation bias based on the interaction energies from the two approaches, reveals larger discrepancy for nickel than for copper. The impact on dislocation bias from the different stacking fault energies of copper and nickel is elaborated. Nickel, which has a larger stacking fault energy, is predicted to have larger swelling rate than copper under the same irradiation conditions.QC 20130530

ITC/USA 2012 Conference Proceedings / The Forty-Eighth Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2012 / Town and Country Resort & Convention Center, San Diego, CaliforniaThis paper contains a description of two types of forward error correction (FEC) codes for shaped offset quadrature phase shift keying, telemetry group version (SOQPSK-TG). The FEC codes are a low-density parity check (LDPC) code and a serially concatenated convolutional code (SCCC). The contributions of this paper are on the system-design level. One major contribution is to design a SCCC code word format that is as compatible as possible with the LDPC code word, which simplifies other aspects of the system design. Another major contribution is to show exactly how demodulators and decoders can be decoupled from each other at the receiver. This simplifies the demodulation process because receiver synchronization is no longer intertwined with FEC decoding. Furthermore, this enables a mix-and-match design, where demods can be chosen based on their performance and complexity tradeoffs. In fact, for the first time, we show how symbol-by-symbol demods can be used with all FEC coding/decoding options, and we also show that these demods have very attractive BER performance given their simplicity.

Full textAbstract:
The presented project explores the current theoretical and experimental tools available within the study group for the Future Circular Collider (FCC) with focus on the electron-positron collider. The aim of the study is to evaluate the current frameworks used for simulation, and investigate the possibility of simulating long-lived particles, that could be dark matter candidates, through them. Pythia cards were run through the framework of Delphes and several different software packages were studied on the journey through the work. It was found that the current framework reconstructs the masses of a Z bosons and Higgs bosons accurately from the ZH signal, which is central for the analysis at the FCC-ee. When the same analysis was applied for the new physics case of a dark matter particle included in the new card for study, a ROOT file was produced indicating that the framework was able to handle the new case. When this card was run through the analysis software however, difficulties arose and a final output could not be achieved. Conclusively, it can be said that the current framework has the possibilities of handling new physics cases but further study is required to be able to run certain software packages on these cases.

Previous issue date: 2007-02-13The FcγRIIA, receptor for the Fc portion of IgG, expressed by macrophages, neutrophils, platelets and dendritic cells, bind to the subclasses of IgG with variable affinity, that can be influenced by the polymorphism in the gene that encodes this receptor. The substitution of the amino acid arginine (R) for histidine (H), in the 131 position, defines three allelic patterns, the homozygote H/H, R/R and the heterozygote H/R, conferring to the FcγRIIA H/H131 a greater affinity to the IgG2 and IgG3 subclasses. This can result in different responses to diverse pathogens. Studies show the importance of Fcγ receptors on the macrophage infection by amastigote forms of Leishmania sp, in addition to those for the complement (CR3) and for mannose (MR). Besides that, genetic factors related to the hosts are involved in the immune response to the leishmaniasis, among them, the FcγRs. Until this time, we haven t found studies relating the receptor FcγRIIA to the leishmaniasis in humans. This way, this work consists in analyzing the allelic polymorphism in the gene that encodes the FcRIIA in individuals with American Tegumentary Leishmaniasis (ATL), evaluate if this polymorphism would be a genetic fact of susceptibility or resistance for this disease, if this would be influencing in the development of the different clinical forms of the ATL, as well in the healing process of the lesions. The FcγRIIA H/R131 polymorphism was analyzed in 88 blood samples of individuals with leishmaniasis and in 98 samples of healthy individuals (control group), using PCR, amplifying a segment of the gene that encodes the FcRIIA, followed by allele-specific enzymatic digestion and agarose gel eletrophoresis 3%. These results showed that the genotypic and allelic distribution of the FcγRIIA H/R131 were similar in the patients with leishmaniasis and in the control group, as well in patients with different clinical forms of the ATL. Concerning the resolution time of the disease, among the patients that had their lesions healed within one month of treatment or after this period, there was a predominance of the alleles R and H, respectively, however these differences were not significant. This way, our study suggests that the allelic polymorphism of the FcγRIIA H/R131 possibly is not a genetic factor of host that is associated to the protection or pathogenesis in the American Tegumentary Leishmaniasis.
O FcyRIIA, receptor para região Fc de IgG, expresso por macrófagos, neutrófilos, plaquetas e células dendríticas, liga-se às subclasses de anticorpos IgG com afinidade variável, que pode ser influenciada pelo polimorfismo alélico no gene que codifica este receptor. A troca do aminoácido arginina (R) para histidina (H) na posição 131 determina três padrões alélicos: os homozigotos H/H e R/R e o heterozigoto H/R, conferindo ao FcγRIIA H/H131 maior afinidade para as subclasses IgG2 e IgG3. Isto pode resultar em diferentes respostas frente a patógenos diversos. Alguns estudos demonstram a importância dos receptores Fcγ na infecção de macrófagos por formas amastigotas de Leishmania sp, em adição aos receptores para complemento (CR3) e para manose (MR). Além disso, vários fatores genéticos do indivíduo estão envolvidos na resposta imune à leishmaniose, dentre esses os FcyRs. Até o presente momento, não encontramos estudos relacionando o receptor FcγRIIA com a leishmaniose em humanos. Assim, o presente trabalho teve como objetivo analisar o polimorfismo alélico no gene que codifica o receptor FcyRIIA em indivíduos com Leishmaniose Tegumentar Americana (LTA), avaliar se este polimorfismo seria um fator genético de susceptibilidade ou resistência para esta doença, se estaria influenciando no desenvolvimento das diferentes formas clínicas da LTA, bem como no tempo de cura das lesões. O polimorfismo do FcγRIIA H/R131 foi analisado em 88 amostras sangüíneas de indivíduos com LTA e em 98 amostras de indivíduos saudáveis (grupo controle), através da PCR, amplificando um segmento do gene que codifica o FcγRIIA, seguida de digestão enzimática alelo-específica e eletroforese em gel de agarose 3%. Nossos resultados demonstraram que a distribuição genotípica e alélica do FcγRIIA - H/R131 foi similar nos pacientes com leishmaniose e no grupo controle, bem como nos pacientes com as diferentes formas clínicas da LTA. Em relação ao tempo de resolução da doença, nos pacientes que tiveram suas lesões curadas com até um mês de tratamento ou após esse período, houve um predomínio do alelo R e do H, respectivamente, entretanto essas diferenças não foram significativas. Assim, nosso estudo sugere que o polimorfismo alélico do FcγRIIA H/R131 possivelmente não é um fator genético do hospedeiro que esteja associado com proteção ou patogênese na Leishmaniose Tegumentar Americana.

Full textAbstract:
Frc, a major gene on chromosome 8, conditions fructan levels in onions (Allium cepa L). In order to assist genetic dissection of this locus, this study aimed to determine the factors influencing varying fructan levels in high- and low-fructan genotypes. Mapping families were developed and analysed to study the genetic architecture for the fructan trait, and to check the association of the identified variables with the Frc locus. To facilitate reliable and practicable sugar assays in onions, a newly-adapted high-throughput microplate enzymatic assay was validated in this study. The reliability of using leaf sugars as a representative of bulb sugars in a mapping population was studied.
Microplate enzymatic sugar assays were carried out on a segregating onion cross to validate the use of maltases in sugar analysis, and the results obtained were validated against HPLC-PAD. Sucrose measured in microplates employing maltases as the hydrolytic enzyme was in agreement with HPLC-PAD results. Maltase enzymes specifically hydrolysed sucrose in onions, providing an alternate tool in place of expensive sugar assay kits. Use of the microplate-enzymatic assay provided a rapid, cheap and practicable method for sugar analysis in onion.
Differences in carbohydrate content, sucrose metabolising enzyme activities and their expression levels were monitored in developing leaf blades and leaf bases of four high- and four low-fructan genotypes. The variation in fructan accumulation between high- and low-fructan genotypes was due to the variation in sucrose metabolism. SPS expression and activity did not vary between high- and low-fructan genotypes. Acid invertase and 1-SST showed significant variation in their activities between the two fructan groups. Post-transcriptional and translational regulation of AI and 1-SST respectively, are suggested.
Mapping populations analysed for non-structural carbohydrates showed very wide segregation for fructan (80 to 600 g kg⁻¹) and other NSC content, and were well-suited for detailed genetic and physiological analysis. Single marker analysis was carried out to study the association between the combined enzyme activity (CEA; acid invertase + 1-SST) and the Frc markers. Significant association between CEA and Frc markers has suggested genes regulating acid invertases or 1-SST or both underlie Frc. Leaf blade NSC did not correlate with bulb sugars and thus cannot be used as a phenotypic marker for early selection of bulb NSC traits.

Concrete technology has changed greatly in the past decades. Steel fibre reinforced concrete (SFRC) is an example of the development in this field. It is obtained by adding fibres that act as a reinforcement of the cement matrix, improving the tenacity, cracking control and durability of the concrete members. In certain applications, SFRC has become an alternative material to concrete reinforced with conventional steel rebar. Despite of numerous advantages of SFRC, problems and uncertainties still exist regarding the design, the characterization and the performance of this material. Furthermore, the structural design and the properties of SFRC in real-scale elements as well as the fibre distribution are not properly clarified. All these issues need to be addressed in order to promote the safe and efficient use of the material.
The objective of this doctoral thesis is to develop a systematic and innovative approach for the design optimization and characterisation of FRC precast segment. In total, 4 subjects are covered: a critical study related to the design of FRC precast segment considering the ductility requirements of the Model Code 2010; the experimental and analytical study of concrete blocks subjected to concentrated loads; the design procedure and experimental research on FRC precast segment for shafts and the anisotropy of the FRC precast segment.
The first subject presents an analysis of the technical requirements demanded by the Model Code 2010 when steel fibres are the only reinforcement for concrete elements. According to this revision, an alternative approach according to the Model Code 2010 which is more compatible with the requirements of the application in tunnels is proposed. This approach may lead to the reduction of the fibre content required to guarantee a minimum ductility of the element. In order to evaluate the repercussion of the ductility criteria in terms of fibre consumption, a case study of Metro L9 of Barcelona is presented.
The second subject contributes to the understanding about the behaviour of concrete blocks subjected to concentrated load. An experimental programme is performed to evaluate the influence of the height-to-length ratios in the mechanical response of the blocks. Based on the observations derived, a strut-and-tie model is adopted to assess the value of the loads Fcr and Fmax for short blocks and long blocks. A case study of Metro Line 9 in Barcelona is conducted, and the results of the study indicates that with an appropriate safety factors for the SLS and the ULS, no traditional reinforcement is required to resist the tensile stresses due to the concentrated loads applied by the jacks of the tunnel boring machine.
The third subject is to verify that it is viable to replace the traditional reinforcement with steel fibres in the segmental lining ring of shaft constructed with vertical shaft machine. An analytical formulation based on MC 2010 is proposed to evaluate the minimum requirements the FRC must fulfil to carry out this replacement. Likewise, an experimental campaign was performed to characterize the mechanical behaviour of both conventional and self-compacting concrete reinforced with fibre content (Cf) between 30 and 60 kg/m3. Posteriorly, another full-scale experimental campaign of bending test on segments is performed to verify the ductile behaviour of two types of segments under failure scenario. These results are used to validate the proposed formula.
The last subject focuses on the study of the anisotropy in terms of fibre distribution and local mechanical response of segments with conventional and self-compacting SFRC. For that, a large number of cores extracted from real-scale segments are tested for the fibre distribution with the inductive method and, then, for the mechanical response with the Barcelona test. A conceptual model for the fibre orientation is proposed based on the average values obtained from the tests.La tecnología del hormigón ha avanzado notablemente en las últimas décadas. En este sentido, el hormigón reforzado con fibras (HRF) es un ejemplo del desarrollo en este campo. Este se obtiene mediante la adición de fibras que actúan como un refuerzo de la matriz de cemento, mejorando la tenacidad y el control de la figuración y, por ende, la durabilidad. En ciertas aplicaciones, HRF se ha convertido en un material alternativo para hormigón armado convencional. A pesar de las numerosas ventajas asociadas al uso del HRF, todavía existen incertidumbres en cuanto al diseño, la caracterización y el desempeño mecánico de este material. En particular, es necesario desarrollar adecuadamente el concepto y requerimiento de ductilidad de las estructuras de HRF así como integrar de forma fidedigna aspectos de orientación y de distribución de fibras en el diseño. Todas estas cuestiones deben abordarse con el fin de promover el uso seguro y eficiente del material. El objetivo de esta tesis doctoral es el desarrollo de un enfoque sistemático e innovador para el diseño y caracterización de dovelas de HRF para la ejecución de revestimiento de túneles. En total, esta tesis se cubren 4 aspectos: un estudio crítico en relación con el diseño del dovelas de HRF teniendo en cuenta los requisitos de ductilidad del Código Modelo 2010; un estudio experimental y analítico de bloques de hormigón sometidas a cargas concentradas; el pre ¿ diseño de dovelas para la ejecución de pozos verticales y el análisis de anisotropía en la distribución y orientación de fibras.En el primer tema se aborda un análisis de los requisitos técnicos exigidos por el Código Modelo de 2010 en estructuras de HRF en las que las fibras son los únicos elementos de refuerzo del hormigón. De acuerdo con esta revisión, se propone un enfoque alternativo y compatible con el MC 2010 más alineado con lo requerimiento estructurales y necesidades resistentes de las dovelas de HRF. Este enfoque conduce a la optimización del contenido de fibra necesaria para garantizar la ductilidad adecuada para estos elementos estructurales. Con el fin de evaluar la repercusión de los criterios de ductilidad en términos de consumo de fibra, se presenta un estudio de caso de Metro L9 de Barcelona.El segundo campo de investigación tratado contribuye al conocimiento en relación al comportamiento de elementos de hormigón sometidos a cargas concentradas. En este sentido, se ha llevado a cabo una campaña experimental para evaluar la influencia del ratio altura ¿ ancho en el mecanismo de rotura de los bloques ensayados. En base a las observaciones, se ha planteado un modelo de bielas y tirantes para evaluar las cargas de figuración y de rotura de los bloques. La formulación propuesta se ha empleado para evaluar dichas cargas en el caso de empuje de los gatos de las dovelas diseñadas para los túneles de la Línea 9 del Metro de Barcelona. Los resultados ponen de manifiesto que, empleando los coeficientes de seguridad adecuados, no se requiere armadura pasiva adicional para resistir los esfuerzos de tracción que se generan en la fase de empuje de los gatos, en el caso particular estudiado. Por último, en la cuarta línea de investigación se estudia en profundidad a nivel experimental la anisotropía de la distribución, cuantía y orientación de las fibras en dovelas de hormigón convencional y de hormigón autocompactante reforzadas con fibras. Para ello, se extrajeron un número elevado y representativo de testigos de las dovelas a escala real fabricadas. Se emplearon métodos no destructivos tipo inductivo para evaluar la cuantía y orientación de las fibras. Asimismo, se empleó el ensayo Barcelona (ensayo destructivo) para evaluar también ambas variables así como la resistencia a tracción residual de los hormigones. En base a los resultados se propone un modelo conceptual para estimar la orientación de las fibras en estos elementos estructurales.

Full textAbstract:
In video streaming it is important that the video stream reaches the users in time, and without errors. To retransmit lost packets in a largescale multimedia video transmission is often unfeasible because of the retransmission delay. Because of that errors require either costly retransmissions or causes a downgrade of performance for the receiving user, an important goal is to minimize the number of errors that occurs when transmitting data during video streaming through a wireless channel. In this paper an adaptation-algorithm is proposed, which adapts itself in such away that the receivers of e.g. the broadcast will receive enough packets in order to be able to FEC-decode the received data in low- as well as high loss-scenarios. The algorithm adapts itself by changing the rate of FEC-encoded redundant packets based on the current packet-loss-rate of the channel, with the aim of optimizing the bandwidth-usage and providing the receiver with playable data meeting deadlines. It adds an additional self-adaptive amount of FEC-encoded redundant packets for each FEC-encoded-session in order to guarantee the ability of the receiver to FEC-decode the data and play the media, even under the conditions in which the inteference-level of the channel increases during the transmission of each such session. Simulations demonstrate that in a wireless channel with a packet loss rate of 10%, using 1000 source packets per FEC-encoded unit, 12.6% redundant packets are required in order to ensure a FEC-decoding-failure probability < 1/1000 .När man streamar video är det viktigt att videostreamen når användarna i tid och utan fel. Att återsända förlorade paket i en storskalig överföring av video är ofta olämpligt p.g.a. den fördröjning som återsändning av paket orsakar. Eftersom att fel kräver antingen kostsamma återsändningar eller orsakar en försämring av prestandan för den mottagande användaren, är det ett viktigt mål att minimera antalet fel som uppstår när man överför data genom en trådlös nätverkskanal. I denna thesis presenteras en anpassningsalgoritm, som anpassar sig själv på sådant sätt att mottagarna av t.ex. broadcast kommer att motta tillräckligt många paket för att kunna utföra en FEC-dekodning av datan i scenarion med både små och stora paketförluster. Algoritmen anpassar sig själv genom att ändra andelen av FEC-kodade redundanta paket baserat på kanalens nuvarande andel av paketförluster, med målet att optimera användandet av bandbredd och att förse mottagaren med uppspelbar data inom deadlines. Andelen FEC-kodade redundanta paket är beräknade så att datan ska kunna dekodas och spelas upp även under de förhållanden där störningsnivån i kanalen ökar under överföringen av datan. Simuleringar, gjorda i en trådlös kanal i vilken 10% av paketen förloras, visar att det med 1000 paket av den ursprungliga datan krävs ytterligare 12.6% redundanta paket per FEC-kodad enhet för att uppnå en sannolikhet för ett misslyckande av FEC-dekodningen < 1/1000 .

IPTV (Internet Protocol Television), a new and modern concept of emerging technologies with focus on providing cutting edge high-resolution television, broadcast, and other fascinating services, is now easily available with only requirement of high-speed internet. Everytime a new technology is made local, it faces tremendous problems whether from technological point of view to enhance the performance or when it comes down to satisfy the customers. This cutting edge technology has provided researchers to embark and play with different tools to provide better quality while focusing on existing tools. Our target in dissertation is to provide a few interesting facets of IPTV and come up with a concept of introducing an imaginary cache that can re-collect the packets travelling from streaming server to the end user. In the access node this cache would be fixed and then on the basis of certain pre-assumed research work we can conclude how quick retransmission can take place when the end user responds back using RTCP protocol and asks for the retransmission of corrupted/lost packets. In the last section, we plot our scenario of streaming server on one side and client, end user on the other end and make assumption on the basis of throughput, response time and traffic.

In a recent judgment by the Free State Provincial Division of the High Court of South Africa it was decided that a trustee who resigns is only relieved from his duties when his name is removed from the letter of authority by the Master of the High Court. This judgment has caused many questions to be raised regarding the implications of the resignation by a trustee.
This judgment and the current legal position of the resigning trustee are investigated in this dissertation. The legal position of the resigning trustee seems to be uncertain, and the mentioned judgment should not be unreservedly accepted as correct. The role and responsibility of the Master of the High Court in this process is considered, as well as the legal position of the resigning trustee, the remaining trustees and third parties contracting with the trust. Certain conclusions are drawn and recommendations are made regarding this aspect of South African trust law.Thesis (LL.M. (Estate Law))--North-West University, Potchefstroom Campus, 2009.

Different groups in the forestry sector were likely to have different views regarding the responsibility for an environmentally sustainable forestry and the benefits of certification and this study aimed to examine the attitudes that existed in the forestry sector to the certification schemes FSC and PEFC. In the study a survey and a questionnaire were sent out to different groups. The investigation was made with respect to three groups: forest owners, forest contractors and employees working with the certification schemes on a daily basis at the forest company Södra. The groups agreed that the owner of the forest had the main responsibility for an environmentally sustainable forestry. The study revealed that all three groups highly valued the environmental aspect of certification. Forest owners also identified financial gain as a benefit. The forest contractors felt that the certification gave orderliness to their work but also saw an economic cost from being certified. The forest company employees found certification as an access to a widermarket with certified products. Half of the forest owners estimated their knowledge of the certification schemes to be inadequate while forest contractors and the employees of Södra valued their knowledge as sufficient. The forest owners had less education about the certification schemes than the other groups.Olika grupper i skogsbranschen riskerar att ha olika syn när det gäller ansvaret för ett miljömässigt hållbart skogsbruk och nyttan med certifiering och den här studien gjordes för att undersöka vilka inställningar som fanns i skogsbranschen till certifieringssystemen FSC och PEFC. Arbetet gjordes med avseende på tre grupper: skogsägare, skogsentreprenörer och anställda som arbetar på skogsföretaget Södra med certifiering i sitt dagliga arbete. I studien skickades en enkät och ett frågeformulär ut. Undersökningen visade att de tre grupperna värderade miljömässigt hållbart skogsbruk med certifiering högt. Som skogsägare fick man en certifieringspremie för det certifierade virke som man sålde. Skogsägarna såg också en ekonomisk vinning med certifiering. Skogsentreprenörerna ansåg att certifiering i högre grad gav ordning och reda i deras arbete men att det fanns en ekonomisk kostnad med att vara certifierad. Skogsföretagsgruppen menade att certifierade produkter gav tillgång till en större marknad för skogsföretaget. Grupperna var överens om att ansvaret för ett miljömässigt hållbart skogsbruk låg på de/den som ägde skogsmarken. Samtidigt uppskattade hälften av skogsägarna att deras kunskaper om certifieringarna var otillräckliga medan skogsentreprenörerna och skogsföretagsgruppen ansåg att deras kunskaper var tillräckliga. Detta kunde bero på att skogsägarna fick mindre utbildning av certifiering än de andra två grupperna. Det här arbetet har visat att grupperna inte har olika syn när det gäller vikten av att ett miljömässigt hållbart skogsbruk bedrivs.

Polyethylene is one of the most widely used synthetic materials produced by mankind and its accumulation in the biosphere is exceeding at an alarming rate. There are several methods to recycle or remediate the waste polyethene apart from land filling and generation of useful products from the waste is on demand for research and development. Ionic liquids are aggressively replacing several organic compounds due to their robust nature and also have novel properties that allow depolymerization of synthetic materials into simpler short chained paraffins. Initial dissolution of polymer using hot toluene followed by agitated depolymerization using EMIM-Cl (AlCl3) ionic liquid for producing fuel grade high calorie organic molecules might be proven successful. This method uses proton sources like sulphuric acid, hydrochloric acid or waters that aid saturation of organic compounds by hydrogen ion exchange. This could be a novel procedure that aims to produce fuel grade products from waste synthetic polymers like polyethene.Program: Master of Science with a Major in Resource recovery – Industrial biotechnology
