Investigation of laser frequency stabilisation using modulation transfer spectroscopyHopper, David J. January 2008 (has links)
Optical frequency standards are necessary tools for accurate measurement of time and length. In practice these standards are stabilised laser systems locked to a known frequency reference. These references are typically the resonant frequencies of the atoms of an absorption medium that have been theoretically calculated to a high degree of accuracy. This thesis describes a combination of experimental and theoretical research performed on modulation transfer spectroscopy (MTS)--a technique used to frequency stabilise a laser in order to produce an accurate frequency reference--with emphasis placed on developing techniques and procedures to overcome the limitations found in existing MTS stabilised laser systems. The focus of the thesis is to generate a highly accurate frequency reference by researching the system parameters that will increase the signal to noise ratio and improve the accuracy of the reference through refinement of the signal structure. The early theoretical interpretation of MTS was effectively a low absorption approximation that occurs at low pressures. This approximation ignores the depletion of beam energy through absorption and is a distinct limitation of the theoretical model in its ability to accurately predict the influence of a range of system parameters on signal strength and structure. To overcome this limitation a 3-D (or volumetric) analysis was developed and is presented here for the first time. This volumetric model is a measure of two depleted beams interacting collinearly in an absorbing medium of iodine and is described to accurately predict the signal maximum as a function of pressure for all wavelengths. This model was found to be more accurate in predicting the influence of system parameters on the signal strength and structure, including that of pump beam intensity, pressure, saturation parameter, cell length and modulation parameters. The volumetric model is a novel approach to MTS theory but is more complex computationally than the traditional low pressure model and therefore more difficult to implement in many situations. To overcome this problem a hybrid model was developed as a combination of the low pressure and volumetric models. The comparison between the rigorous volume model and the hybrid model indicate that there is a deviation in the signal strength at high pressures. However, the agreement was very good in the pressure regimes that are commonly used to realise actual frequency references. Comparison of the hybrid model to experimental data was performed over a range of different wavelengths (532 nm, 543.5 nm, 612 nm and 633 nm) and found to be in close agreement. This gives confidence in the model to accurately predict signal strength and structure in any situation. Three mechanisms have been identified that limit the accuracy of frequency references due to the creation of residual amplitude modulation (RAM) where it shifts the frequency of the reference. The influence of RAM is included in the hybrid model as a ratio of the amplitude modulated and frequency modulated components of the saturating beam. These RAM production mechanisms result from the modulation of the saturating beam, the overlap of the beams in the medium, and the differential absorption of the sidebands in the medium. While the first mechanism has been previously reported the latter two are discussed here in detail for the first time. RAM generated by the modulators used (acousto-optic or electro-optic modulators) was typically of the order of 10% to 12%, depending on the excursion of the created sidebands. RAM generated by an asymmetric beam overlap with the modulators used was found to be as large as 30%. A combination of these two independent mechanisms can be used to provide a "RAM-free" state of the system by using one to cancel the effects of the other. The third RAM generation process--medium induced RAM--is difficult to remove but through a careful combination of absorption related parameters--namely, pump intensity, cell length, pressure and detector phase--the effects of RAM can be removed, leading to a distortion free MTS signal. Further investigation into the predictions provided by the hybrid model shows that there is a complex relationship between cell length and the optimum pressure required for maximum signal strength, such that longer cell lengths will not necessarily improve the signal strength. This is contrary to conventional thinking and is important in the MTS design process to reduce unnecessary costs and improve the signal to noise ratio and frequency accuracy. Optimisation of frequency stabilised laser systems using MTS are generally performed using trial and error. Comparison of these optimum parameter values to those predicted by the hybrid model show that for popular wavelengths such as 532 nm they are similar. In addition, the hybrid model is able to predict the frequency shifts that arise within the system parameters used and has shown that existing systems being used at 532 nm, 633 nm and 778 nm could improve their signal to noise ratio and accuracy through a variation in the parameters. A methodology based on the hybrid model is presented that can be used to calculate the optimum parameters for maximum signal strength and a "RAM-free" state for any wavelength. This systematic approach can therefore be used to guide the design of actual frequency stabilised laser systems prior to and during the design process.

Informations- och kommunikationsteknik inom Sva : – Fem lärares motivation, teknik och metoder inom IKT / Information and communications within SAS : - Five teachers' motivation, technology and methods within ICTWahlström, Maria January 2017 (has links)
Syftet med denna intervjustudie är att se hur lärare arbetar med informations- och kommunikationsteknik (IKT) i sin undervisning, inom svenska som andraspråk. Kvalitativa semistrukturerade forskningsintervjuer gjordes med Sva-lärare i Stockholm. Studien utgår ifrån två övergripande forskningsfrågor; dels hur lärarna motiverar användandet av IKT och dels vilka metoder och verktyg inom IKT som används. Resultatet visar att tekniken har en central del i lärarnas undervisning och tjänar olika syften. Dels blir eleverna mer motiverade när de aktiveras och själva tar tag i sitt lärande, det blir också mer underhållande undervisning och det underlättar en individanpassad undervisning, stimulerar olika inlärningsstilar och kan underlätta lärarens arbete. Lärarrollen ersätts inte av tekniken, utan får nya former då läraren kan möta eleverna oberoende av tid och rum. Verktygen de använder skiljer sig åt men samtliga arbetar med lärplattformar (via mobil, datorer eller I-pads) och samtliga låter eleverna ha sina privata mobiltelefoner till hjälp. Lärarna upplever utmaningar, såsom när ITsatsningar läggs ner, de upplever sig ensamma om sitt engagemang i skolan eller får brist på tid att utforska teknikens möjligheter ytterligare. / The purpose of this study is to investigate how teachers work with information and communication technologies (ICT) in teaching Swedish as a second language. Qualitative semi-structured research interviews where done with five teachers in Stockholm. The study is based on two overarching research questions; the teachers reason of using ICT and second which methods and tools they use. The result shows that ICT has a central role in teaching and serve different purposes. The students are more motivated when they are activated and they reach higher control in their learning, it also becomes more entertaining teaching and it facilitates individualized teaching, stimulates different learning styles and more. The role of the teacher is not replaced by technology, but it takes on new forms when the teacher can meet students regardless of time and place. The tools they use are different but they all work with learning management systems (via mobile, computers or I-pads) and all teachers allows students to have their private mobile phones. Teachers are experiencing challenges such as IT investments closed down, they feel alone in their involvement in school or have a lack of time to explore further opportunities with the digital work.

A Comparison of Microarray Analyses: A Mixed Models Approach Versus the Significance Analysis of MicroarraysStephens, Nathan Wallace 20 November 2006 (has links) (PDF)
DNA microarrays are a relatively new technology for assessing the expression levels of thousands of genes simultaneously. Researchers hope to find genes that are differentially expressed by hybridizing cDNA from known treatment sources with various genes spotted on the microarrays. The large number of tests involved in analyzing microarrays has raised new questions in multiple testing. Several approaches for identifying differentially expressed genes have been proposed. This paper considers two: (1) a mixed models approach, and (2) the Signiffcance Analysis of Microarrays.

The nature, the extent and possible implications of director interlock in South African listed companiesNeuhoff, Louis Marais January 2020 (has links)
Recently, corporate scandals rocked the South African financial landscape, prompting the re-examination of existing corporate governance practices and renewed scrutiny of corporate governance institutions and mechanisms. One of these practices, a phenomenon called “director interlock”, was scrutinised in this study. A quantitative and inductive approach was used in this research to scrutinise companies listed on the Johannesburg Stock Exchange, as well as the directors who served on their boards during the periods researched, namely, 2010 and 2016, with the purpose of considering the consequences of director interlock in a South African context. Appropriate sources on corporate governance, director interlock and network analysis were accessed. Social network analysis was applied to analyse and map the extent, nature and structural dynamics of director interlock statistically in all South African listed companies in respect of 2010 and 2016 with a view to considering the causes and consequences of identified changes between 2010 and 2016, and possible implications of those changes for corporate governance in South Africa. Both periods occurred shortly after times of financial turmoil or contracting economic growth, where, in line with global trends, financial consolidation and a possible decline in economic activity and board sizes of companies would be expected. The concept of centrality, comprising three components, was used in the statistical social network analysis. These components were degree centrality, which is an indicator of the number of connections and the degree of activity of a company or a director, closeness centrality, which is an indicator of the closeness of a company or a director to other companies or directors within a network and the number of steps from that company or director to other companies and directors in the network, and betweenness centrality, which is a measure of the centrality of a company or a director and the extent to which the company or the director acts as a bridge between and connects with other well-connected companies and directors in the network. The following striking findings emerged from this research: a massive increase in the average board size between 2010 and 2016, a resultant increase in the density of networks between 2010 and 2016, and an apparent shift away from the dominance of mining houses described in earlier studies to financial services companies in 2010 and retail companies in 2016. In the literature review the existence of a global elite in the structure of company boards was pointed out, and the question was asked whether there is any evidence of the existence of a similar elite in South Africa and, if so, whether there have been any changes in the makeup, characteristics or nature of such an elite from 2010 to 2016. Further, the question was asked whether any changes can be observed regarding the central actors of company boards in the local economic power network. The research results indicate that
iii
there was an apparent reversal of transformational gains towards the re-establishment of white male dominance in the ultra-elite echelons of directors in the South African network by 2016. In the absence of conclusive evidence emanating from this research, the value of director interlock is still hotly debated. Is the practice of director interlock beneficial or damaging to corporations and the wider economic landscape, or could it be both beneficial and damaging? This study provides conclusive evidence that the value of interlock depends on the way in which it is applied, taking into account how the causes, consequences and dynamics of director interlock are manifested in individual companies. While evidence suggests that director interlock, if applied correctly, can be beneficial, the recent Steinhoff debacle was used to illustrate that it can also be detrimental, depending on how it is applied. This study emphasised the value of social network theory, resource-dependence theory, agency theory, small-world theory and power dynamics, specifically in research into corporate governance and related fields of study. This research undoubtedly contributes to the body of knowledge on corporate governance in general and the structure and functioning of company boards, inclusive of director interlock, in particular. The guidelines that emerged from this study could be used to identify board structures and strategically positioned directorship candidates for board appointments and to avoid potentially destructive patterns that may even lead to corporate failure. / Maduzane nje, kuvele amahlazo ezinkampani ezinkulu zezezimali eNingizimu Afrika, lokhu okwenze ukuthi kuhlolwe kabusha inqubo nenkambiso yamanje yolawulo lwezinkanpani ezinkulu, kanti futhi lokhu kwavuselela ukuhlaziywa kwezikhungo zezolawulo lwezinkampani ezinkulu kanye nezindlela zokwenza lokhu.

Le droit des sociétés à l’épreuve de la société privée européenne / Company law to the test of the European private companyGaillard, Fabien 11 June 2013 (has links)
« L’Europe ne se fera pas en un jour, ni sans heurts.», dixit Monsieur Robert Schuman. Tel est le constat qui peut encore être fait à l’heure actuelle avec l’adoption, après trente ans d’intenses débats au niveau européen, de la Societas Europaea, introduite en droit français avec la loi du 26 juillet 2005 pour la confiance et la modernisation de l’économie, complétée par les décrets du 14 avril 2006 et du 9 novembre 2006. La même analyse peut s’appliquer à la proposition du règlement de la commission européenne relatif au statut de la société privée européenne faite le 25 juin 2008, en cours d’examen devant le Parlement Européen. Il s’agit de démontrer l’existence de normes communautaires flexibles propices au développement des normes statutaires, à l'image de celles applicables à la société privée européenne (SPE) d'origine communautaire et d'essence contractuelle. La SPE doit être analysée comme structure sociétaire, symbole de l’émancipation du droit communautaire et vecteur du principe de libre établissement des sociétés, à la fois par rapport à sa « grande cousine », la société européenne, et à travers l’étude des normes communautaires comme éléments nécessaires au bon fonctionnement des structures européennes.La question est enfin de savoir si le recours à la SPE constitue un instrument pertinent dans les opérations de restructuration intra-communautaire. Deux axes de réflexion semblent s’imposer : l’aménagement des relations contractuelles intragroupe via le modèle de la SPE et la SPE comme élément moteur dans le cadre des opérations de fusion intracommunautaire. / “Europe will not be made in a day, nor without any clashes,” according to Mr Robert Schuman. The statement proved to be true with the adoption, after thirty years of intense debates at the European level, of Societas Europaea, introduced into French law with the bill of July 26, 2005 for the confidence and modernization of the economy, supplemented by the decrees of April 14, 2006 and November 9, 2006. The same analysis can be made of the European Commission proposals for the regulations relating to the statute of the European private company made on June 25, 2008, and now under consideration before the European Parliament. The question is to show the existence of flexible Community standards favourable to the development of statutory standards, in the image of those applicable to the European Private Company of Community origin and which is contractual in essence. The European Private Company should be analysed as a member structure and a symbol of the emancipation of Community legislation as well as a vector of the principle of free establishment of companies both in relation to its “big cousin,” the European Company, and through the study of Community standards as necessary elements to the correct operation of European structures. The next step is to question if resorting to the European Private Company constitutes a relevant instrument in the operations of intracommunitarian reorganization following two main lines of investigation: the adjustment of contractual intragroup relations via the model of the European Private Company and the European Private Company as a mainspring within the framework of intracommunitarian fusion operations.
