Sammanfattning

Detta examensarbete inom produkt- och processutveckling har genomförts på uppdrag av SMS Smart Media Solutions AB i Stockholm. Syftet med arbetet har varit att ta fram och utveckla ett stativ som ska kunna hålla upp till 4 stycken datorskärmar och som tillåter ergonomisk anpassning och användning. Under projektets gång har antalet skärmar utökats från 4 till 8 för att tillmötesgå uppkomna kund- och marknadskrav. Målet med examensarbetet har varit att ta fram en färdig prototyp som ska kunna ligga till grund för tillverkning av stativet.

Under utvecklingsarbetet har verktyg som QFD, funktionsanalys, Ishikawa-diagram, Pugh’s jämförelsematris och FMEA använts för att säkerställa att kund-, marknads-, kvalitets och funktionskrav uppfylls. Arbetet inleddes med en idégeneringsfas som utmynnade i ett antal olika koncept. Koncepten utvärderades utifrån kravspecifikation, funktion, antal standardkomponenter och pris. Konceptet som ansågs starkast utvecklades till en prototyp vilken i sin tur testades och utvärderades.

Resultatet av examensarbetet är att det utvecklade stativet är infört i SMS Smart Media Solutions’ produktportfolio och kommer att finnas med i SMS’ produktkatalog för 2010. Stativet motsvarar alla krav som satts upp i kravspecifikationen och alla problemen som definierats i problemformuleringen har lösts.

 


Abstract

This thesis in product and process development has been made in cooperation with SMS Smart Media Solutions AB in Stockholm. The aim of the thesis has been to develop a new display bracket that can carry up to 4 monitors and that allows ergonomically adjustments and usage. During the project the amount of maximum monitors has been changed from 4 to 8 to meet the demand of the customers and the market. The goal of the thesis has been to develop a prototype that would be the ground of the future bracket that will be offered in SMS Smart Media Solutions’ product portfolio.

To make sure that the developed bracket meets all the demands and criteria, tools like QFD, analysis of function, Ishikawa diagram, Pugh’s matrix and FMEA have been used. The process of the product development started with brainstorming and concept generation. The developed concepts were evaluated using analysis of requirements, costs, functions and the amount of used standard components. The winning concept was carried on into a prototype that was tested, evaluated and improved.

The result of the thesis is that the developed bracket has been integrated to SMS Smart Media Solutions’ product portfolio and will be added to SMS’ product catalogue for 2010. The final bracket met all the criterions that were set in the specification of requirements and all the problems form the problem statement were solved.

Résumé :
Soit $T$ une constante positive. Dans le présent travail, nous nous intéressons à l'existence d'une solution $T$-anti-périodique et d'une solution $T$-périodique de l'équation différentielle d'Abel \begin{equation*} \theta^{\prime}=f_0+\sum_{j\in \mathbb N} f_j\theta^j \end{equation*} avec $f_j$, ($j \in \lbrace 0, 1, 2, ...\rbrace$) à variation bornée sur $[0, T]$. Nous allons généraliser cette équation au cas impulsif où $\theta$ et $\theta^{\prime}$ subissent des sauts dépendants de l'état. Le premier chapitre consiste en un rappel de quelques définitions, notions de bases et résultats fondamentaux de l'analyse réelle et fonctionnelle que nous allons utiliser tout au long des chapitres 2 et 3. Au deuxième chapitre, on étudie l'existence d'une solution $T$-anti-périodique dans le sens que $\theta(0)= -\theta(T)$. Les conditions que nous imposons nous permettent d'utiliser le théorème du point fixe de Banach. Cette méthode nous donne non seulement l'existence d'une solution, mais aussi un moyen de trouver la solution numériquement ainsi qu'une majoration de la vitesse de convergence uniforme, d'une suite d'itérations de Picard vers la solution. Les résultats obtenus dans ce chapitre sont publiés dans \cite{BelleyGueye17}. Au troisième chapitre, on étudie l'existence d'une solution T-périodique pour la même équation. On utilise encore le théorème du point fixe de Banach pour garantir l'unicité de la solution. L'unicité est nécessaire pour que la fonction moyenne $M(\mu)$ que nous introduirons plus tard soit bien définie. Cette méthode nous donne également, non seulement l'existence d'une solution, mais aussi un moyen de trouver la solution numériquement ainsi qu'une majoration de la vitesse de convergence uniforme d'une suite d'itérations de Picard, vers la solution.

Résumé :
Tesis para optar al título de Magíster en Administración
El presente plan de negocios nace del vínculo con la Facultad de Medicina de la Universidad de Chile, con el objetivo de determinar el potencial de mercado del Producto Reportero, un sistema de monitoreo y control automático, que posee características únicas en el mercado, cómo son el sistema de mensajería electrónica, monitoreo y control vía web. En base al estudio de mercado realizado, se determino que existe una demanda insatisfecha que las empresas existentes no han logrado cubrir por los costos elevados de las soluciones técnicas factibles de implementar y por un déficit importante de su gestión comercial. Considerando las características del producto y la definición de mercado relevante para el, se elaboró un plan de negocio para la empresa CONTROL SOLUTION1, que comercializará Reportero, adoptando una estrategia competitiva de enfoque, orientándose a pequeñas y medianas empresas de la Región Metropolitana, de rubros caracterizados por contar con procesos productivos donde el monitoreo de variables físicas es un factor crítico. La estrategia de marketing, contempla la comercialización del producto mediante multicanales: alianzas comerciales, alianzas complementarias y venta directa al cliente final. Las decisiones estratégicas de las alianzas operará en función de los diversos segmentos de mercado. Esta industria se caracteriza por presentar un atractivo importante, con proveedores que presentan un poder negociador medio, donde el poder negociador de los compradores y sustitutos es bajo, y no existen importantes represalias ni ambientes hostiles, lo que nos lleva a estimar que se pueden obtener grados importantes de rentabilidad. La evaluación financiera muestra que utilizando una tasa de descuento de un 35%, la empresa tiene una valoración hoy de M$ 6.675 y una TIR de 67%. En dicha evaluación hemos evaluado el Proyecto Puro, es decir financiado 100% con capital. Por otra parte, el Break Even se logra a partir del séptimo mes, con un volumen de 12 reporteros vendidos. Asimismo, el flujo de caja alcanza su equilibrio en el octavo mes con un volumen de 14 reporteros. En cuanto a las sensibilizaciones y posibles escenarios, hemos tomado variables estratégicas del negocio. Entre ellas, podemos distinguir, los efectos de potenciales entrantes (mercados locales como extranjeros), y aspectos internos del negocio, entre otros. Lo anterior, se traduce en los posibles efectos en la demanda, márgenes y precios, los cuales son muy sensibles y que frente a estos debemos procurar medidas. Finalmente, inferimos que es necesario patentar Reportero, de manera de minorizar potenciales riesgos y viabilizar nuestro negocio en cuanto a nuestras estimaciones de tres años.

The Kirkwood-Buff (KB) theory of solutions, published in 1951, established a route from integrals over radial (pair) distribution functions (RDFs) in the grand canonical ensemble to a set of thermodynamic quantities in an equivalent closed ensemble. These “KB integrals” (KBIs) can also be expressed in terms of the particle-particle (i.e., concentration or density) fluctuations within grand canonical ensemble regions. Contributions by Ben-Naim in 1977 provided the means to obtain the KBIs if one already knew the set of thermodynamic quantities for the mixture of interest; that is, he provided the inversion procedure. Thus, KB theory provides a two-way bridge between local (microscopic) and global (bulk/thermodynamic) properties. Due to its lack of approximations, its wide ranging applicability, and the absence of a competitive theory for rigorously understanding liquid mixtures, it has been used to understand solution microheterogeneity, solute solubility, cosolvent effects on biomolecules, preferential solvation, etc. Here, after using KB theory to test the accuracy of pair potentials, we present and illustrate two extensions of the theory, resulting in a general Fluctuation Solution Theory (FST). First, we generalize KB theory to include two-way relationships between the grand canonical ensemble’s particle-energy and energy-energy fluctuations and additional thermodynamic quantities. This extension allows for non-isothermal conditions to be considered, unlike traditional KB theory. We illustrate these new relationships using analyses of experimental data and molecular dynamics (MD) simulations for pure liquids and binary mixtures. Furthermore, we use it to obtain conformation-specific infinitely dilute partial molar volumes and compressibilities for proteins (other properties will follow) from MD simulations and compare the method to a non-FST method for obtaining the same properties. The second extension of KB theory involves moving beyond doublet particle fluctuations to additionally consider triplet and quadruplet particle fluctuations, which are related to derivatives of the thermodynamic properties involved in regular KB theory. We present these higher order fluctuations obtained from experiment and simulation for pure liquids and binary mixtures. Using the newfound experimental third and fourth cumulants of the distribution of particles in solution, which can be extracted from bulk thermodynamic data using this extension, we also probe particle distributions’ non-Gaussian nature.

Résumé :
The integration of services and products into solutions can open up new business opportunities for firms. This thesis concerns how firms can provide solutions that are perceived as high quality. Solutions are often provided over several years, which implies a changed customer relationship compared to product provisions. Since the solution aims to support the customer’s activities, firms face new challenges when introducing solutions. One challenge is to integrate all components and activities of the solution, and simultaneously support the customer’s activities. In addition, the firm must ensure that the solution and all of its parts are of high quality. Most of the existing research on quality is related to the management of a firm’s internal activities and the interaction during exchange. Within the research on quality, customer orientation means that a firm should manage the relevant product or service to meet customer requirements. When this is achieved, the product or service is of high quality. Since solutions are seen as services and products that are integrated as an outcome, as well as a customer relational process that aims to support the customer’s activities, firms have little to learn from previous research about the quality of solutions. The aim of this thesis is to increase knowledge about how to manage solution quality. The thesis combines insights from research on quality with research on solutions and servitization. Three research questions are answered. The first question concerns the content of solution quality; the second deals with how firms can, with support from interventions, meet the new challenges that arise from solution provision; and the third question concerns how customers can be involved to achieve solution quality. The research questions are answered through five papers based on literature studies and empirical data. The papers contribute to an increased knowledge of solution quality and how firms can work to achieve it. The results of the thesis suggest that solution quality is built on seven quality dimensions: reliability, communicability, internal consistency, empathy, approachability, tangibility, and adaptability. In addition, knowledge of processes and customer relationships are two prerequisites for the concept. These dimensions and prerequisites are supported by interventions that can provide a change. However, it has become evident that whatever intervention is used must be related to the dimensions that are supposed to be improved. Furthermore, customer involvement is argued to be an intervention to support the prerequisites for solution quality, especially during the solution  development. The results of this thesis extend the research on quality by increasing the knowledge of the solution quality concept and by changing the view of customers and their involvement during solution development.
Den här avhandlingen berör hur företag kan möjliggöra så att produkter och  tjänster, integrerade i så kallade helhetslösningar, kan levereras med hög kvalitet. Helhetslösningar levereras ofta över en längre tid vilket medför en förändrad kundrelation till skillnad mot när endast en produkt levereras. Helhetslösningar syftar till att stödja kunden i dess aktiviteter. Det medför att företagen möter nya utmaningar. En utmaning är att få den komplexa helhetslösningen, bestående av olika komponenter och aktiviteter, att passa ihop och samtidigt bidra till att stötta kundens aktiviteter. Dessutom behöver företagen säkerställa att helhetslösningen och alla dess delar har hög kvalitet. Tidigare forskning inom kvalitetsutveckling berör företags interna processer och aktiviteter. När man inom kvalitetsutveckling talar om kundorientering innebär det att företaget med interna medel ska arbeta för att möjliggöra så produkten eller tjänsten möter kundens specifikationer. När detta är uppnått har produkten eller tjänsten hög kvalitet. Företagen har här inga riktlinjer att följa när de ska leverera helhetslösningar som ska anpassas efter kundens aktiviteter och när en så tydlig kundrelation ska utvecklas. Det finns med andra ord ingen vägledning för vad som är kvalitet eller hur man möjliggör hög kvalitet på helhetslösningar. Den här avhandlingen visar vad som ingår i begreppet kvalitet när det gäller helhetslösningar (lösningskvalitet) samt hur företag kan möjliggöra det. Tre olika frågor har huvudsakligen behandlats. Den första frågan besvarar vad lösningskvalitet innehåller. Den andra berör hur företag med hjälp av åtgärder kan bidra till en förändring inom företaget för att möta de nya utmaningar som uppstår med att leverera helhetslösningar. Den tredje frågan berör på vilket sätt kunden kan involveras för att uppnå lösningskvalitet. För att besvara frågorna har ett antal studier baserade på empiriskt material genomförts, och fem artiklar har författats under forskningsprocessen. Artiklarna bidrar till att öka förståelsen för lösningskvalitet och hur företag kan arbeta för att uppnå det. Avhandlingens resultat visar att lösningskvalitet består av sju olika dimensioner: tillförlitlighet, kommunicerbarhet, intern överensstämmelse, empati, nåbarhet, påtaglighet, och anpassningsbarhet. Dessutom är kunskap om processer och kundrelationer två förutsättningar för att uppnå lösningskvalitet. Dimensionerna betraktas som riktmärken för lösningskvalitet som företag kan arbeta mot. Dimensionerna och förutsättningarna stöttas i sin tur av åtgärder som används för att bidra till den interna förändringen inom företaget. Resultaten visar dock att använda åtgärder inte alltid leder till en förändring. Endast noga utvalda åtgärder som relaterar till en specifik dimension möjliggör en förändring. Exempel på en möjlig åtgärd är kundinvolvering. Speciellt vid utveckling av helhetslösningar, betraktas kundinvolvering som en möjlig åtgärd för att stötta förutsättningarna till lösningskvalitet. Resultaten i den här avhandlingen bidrar huvudsakligen till en ökad kunskap om vad kvalitet är när det gäller helhetslösningar. Ytterligare ett bidrag är att föreslå kundens förändrade roll under utveckling och vid leverans av helhetslösningar för att uppnå lösningskvalitet.

Résumé :
The increased use of computer networks has lead to the adoption of Internet-based solutions for reducing telephony costs. This has proved to be a boon to callers who can reach the other party directly via the Internet. Unfortunately numerous business persons still need to call to and from mobile phones which are currently a domain where the customers are generally tightly bound to their operators. To provide a simple solution to this problem for companies, Opticall AB has designed an integrated system called the Dial over Data solution, coupling a mobile interface with a low-rate communication channel, which allows calls to be originated remotely at the best price, exploiting the customer company's existing network. This scheme allows the customer company to easily control telecommunications costs, to monitor their employees' efficiency, and more generally speaking to claim a central role in the communications of their employees. The proposed solution allows distant callers (usually employees of the customer company) to benefit from the company's internal network, which is usually more cost effective and offering connectivity to more networks than a cell phone. The Dial over Data solution enables communication between any phone accessible from the customer company's telephony network (such as SIP clients, landline phones, and mobile phones) at a lower cost.</p> This thesis project analyzes existing technologies and compares them to the pre-existing prototype to ascertain the validity of the method and of the components used. This project also explains the improvements brought to the features offered by the DoD solution: the initial prototype has been developed into a stable and functional product, and has been tested internally. Prompted by a need for scalability and additional features, the replacement of Asterisk for the handling of SIP calls by other SIP servers has also been considered and tested.
Den nuvarande ökningen av datanätverk har lett till adoptionen av Internetbaserade lösningar för att förminskar kostnader inom telefoni. Tyvärr behöver åtskilliga affärsmän fortfarande ringa till och ifrån mobiler som återstår som ett område där kunderna är fastkedjade till deras operatörer. För att tillföra en enkel lösning till detta problem för kundföretag har Opticall AB planlagt ett integrerat system som kallas Dial over Data som kopplar ihop ett mobilt gränssnitt, med en billig kommunikationsmedel, som tillåter telefonsamtal påbörjas avlägset på det billigaste priset tack vare företagets nätverk. Det ger möjligheten till kundföretaget att vara centralt för sina personals kommunikationer. Det medger ett enkelt sätt att kontrollera kostnader samt övervaka personalens effektivitet. Den Dial over Data lösningen är en lösning som tillåter avlägsen besökarna med kundföretagets inre nätverk kommer att dra nytta av eftersom det är mer kostnadseffektiv och flexibel än en blott mobiltelefon. Denna möjliggör kommunikation mellan SIP-klienter, fast telefoni och mobiltelefoni för en lägre kostnad till företaget utan att framkalla besvär för sina anställda. Konnektiviteten till företagets inre nätverk samt en låg besvärlighetsnivå är garanterade respektive genom konfigurationsförmågan av produkten och ett praktiskt gränssnitt som är redo för korporativkontaktlistor och visar alla informationen som är relevanta till förbrukarnas erfarenhet.</p> Det här avhandlingsprojektet analyserar existerande teknologier och sätter dem i relation till den sedan tidigare framtagna prototypen för att utröna validiteten hos metoden och beståndsdelar. Projektet förklarar även de förbättringar som gjorts till de egenskaper som erbjuds av DOD-lösningen: prototypen har utvecklats till en stabil och funktionell produkt och har testats internt. Driven av behovet för skalabilitet och ytterligare egenskaper har ersättandet av Asterisk för hantering av SIP samtal av andra SIP servers övervägts och testats.

Wildcat Creek in Riley County, KS has repeatedly flooded in the past 5 years causing significant damage to the watershed, private property, and community livelihood. Strategically placing wetlands throughout the watershed can help reduce stormwater runoff, increase infiltration, and increase wildlife habitat. A watershed assessment was completed to determine the best location for wetlands in the Wildcat Creek Basin. Two watershed-scale plans for wetlands were derived and evaluated based upon estimation of stormwater runoff and quality of wildlife habitat. Wetlands were then examined and incorporated into existing land cover and land uses at the site-scale for an existing golf course. Three proposals for the nine hole course (for best golf experience, wildlife habitat, and wetland creation) were developed to reflect expansion options from a Par 30 to a Par 34 or 35 course. Each proposal was evaluated based on wetland capacity from estimated stormwater runoff, quality of wildlife habitat, playability of the golf course for all skill levels, and cost of implementation. After this evaluation, the wetland proposal was moved forward and further developed into a proposal that is best suited for the site. Following wetland implementation, stormwater runoff can be collected on-site to prevent runoff and flooding at the golf course and downstream. In order to solve flooding problems in the Wildcat Creek watershed, a series of wetlands can be implemented at the smaller site scale, like the Wildcat Creek Golf Course site, throughout the watershed. Wetlands are one component of a larger stormwater management system that is needed to reduce flooding of the Wildcat Creek and the flood-prone area of Manhattan, KS.

Résumé :
Computer networks are continuously evolving and growing in size and complexity. New technologies are being introduced which further increases the complexity. Net- work Service Orchestration is all about pushing configuration out into the network devices automatically without human intervention. There can be issues that causes the orchestration to fail. In many cases manual operations must be done to recover from the error which is very contradicting since the goal of orchestration is that it should be fully automated. There is some indication that the errors that are being solved manually could be de- tected and handled by a feedback mechanism. This thesis work aimed to build on current insight and if possible, verify that the feedback mechanism is a viable method. After consideration on different ways to solve the research question, the choice fell on creating a test environment where the approach was tested. The test environment was used to investigate if a network orchestration system could be integrated with a feedback mechanism. The result of this project presents a way to automatically de- tect a network failure and send feedback to a Network Service Orchestrator. The or- chestrator is then able to identify and correct the error.
Datornätverk utvecklas kontinuerligt och växer i storlek och komplexitet. Nyteknik införs som ytterligare ökar komplexiteten. Nätverksservice orkestrering handlar om att skicka ut konfiguration automatiskt till enheter i nätverket utan mänsklig in- blandning. Det kan finnas problem som gör att orkestreringen misslyckas. I många fall måste manuella åtgärder utföras för att lösa problemet, vilket är mycket motsä- gelsefullt, eftersom målet med orkestrering är att det ska vara fullt automatiserat. Det finns indikationer på att fel kan detekteras och hanteras av en återkopplings- mekanismen. Detta examensarbete syftar till att bygga på aktuell insikt, och om möj- ligt, verifiera att återkopplingsmekanismen är en möjlig metod. Efter överväganden på vilka olika sätt som projektmålet kunde uppnås föll valet på att skapa en testmiljö där ansatsen kunde testas. Testmiljön användes för att utreda om ett nätverksorkestreringssystem kan integreras med en återkopplings mekanism. Resultat av projektet presenterar ett sätt att automatiskt upptäcka ett nätverksfel och skicka återkoppling till ett nätverksorkestreringssystem. Nätverksorkestreraren kan sedan detektera och åtgärda felet.

Résumé :
As is the way with books in general this document is presented in the form of chapters (seven in number) devoted to individual topics relating to the overall topic of Gaia astrometric data processing. We progress logically from the satellite to the equations for the astrometry to the implementation of a software system to process Gaia observations. After this we look at a few key astrophysical issues for Gaia and explain tests which have been carried out, using the implementation, concerning these effects. A few appendices provide additional information. Here an overview paragraph is provided for each of the chapters: This introductory chapter Section 1 provides an overview of the work as well as an overview of the satellite hardware for the reader unfamiliar with Gaia. In Section 2 the equations underpinning the astrometric solution are explained and developed toward the algorithms actually coded in the system. Section 3 provides details of the Java software framework which hosts the equations previously described. The framework itself has been tuned to effectively process Gaia observations and is the main original content of the thesis. This system is known as the Astrometric Global Iterative Solution or AGIS. Having looked at the implementation, a few of the astrophysical effects and design decisions which influence the solution are described in Section 4. Although no data has yet been received from Gaia, extensive simulations have been performed in the Gaia community. Some of the AGIS tests relating to the astrophysical phenomena described in Section 4 are reported in Section 5. In this manner a demonstration of the effectiveness of AGIS is presented. A discussion and overview of the development approach adopted for A GIS is presented in Section 6. The eXtreme programming approach is particularly suited to science development and worked well for this project in the form presented. Brief conclusions are drawn in Section 7. Appendix A provides a primer on Quaternions which are used for attitude modelling. A complete list of the mind boggling acronyms used in this document appears in Appendix B. Finally some published papers are included in Appendix C.

Texte intégral
Résumé :

The aim of this thesis was to investigate amphiphilic molecules in aqueous solution. The work was divided into two parts. In the first part the effects of different counterions on phase behavior was investigated, while the second part concerns the 1-monooleoyl-rac-glycerol (MO)/n-octyl-β-D-glucoside (OG)/2H2O-system.

The effects of mixing monovalent and divalent counterions were studied for two surfactant systems, sodium/calcium octyl sulfate, and piperidine/piperazine octanesulfonate. It was found that mixing monovalent and divalent counterions resulted in a large decrease in cmc already at very low fractions of the divalent counterion. Moreover, the degree of counterion binding for piperidine in the piperidine/piperazine octanesulfonate system was much higher than predicted, probably due to the larger hydrophobic moiety of piperidine.

The effects of hydrophobic counterions were studied for eight alkylpyridinium octanesulfonates (APOS). The results were discussed in terms of packing constraints. The anomalous behavior of the 2H2O quadrupolar splittings in the lamellar phases was explained by the presence of two or more binding sites at the lamellae surface.

The MO/OG/water system was studied in general and the MO-rich cubic phases in particular. When mixing MO and OG it was found that OG-rich structures (micelles, hexagonal and cubic phase of space group Ia3d) could solubilize quite large amounts of MO, while the MO-rich cubic structures where considerable less tolerant towards the addition of OG. The micelles in the OG-rich L1 phase were found to remain rather small and discrete in the larger part of the L1 phase area, but at low water concentration and high MO content a bicontinuous structure was indicated. Only small fractions of OG was necessary to convert the MO-rich cubic Pn3m structure to an Ia3d structure, and upon further addition of OG a lamellar (La) phase formed. Since the larger part of the phase diagram contains a lamellar structure (present either as a single La phase or as a dispersion of lamellar particles together with other phases), the conclusion was that introducing OG in the MO structures, forces the MO bilayer to become more flat. Upon heating the cubic phases, structures with more negative curvature were formed. The transformation between the cubic structures required very little energy, and this resulted in the appearance of additional peaks in the diffractograms.

Texte intégral
Résumé :
Methylation of CpG dinucleotides is the major epigenetic modification of mammalian DNA which results in the remodelling of transcriptionally active euchromatin to transcriptionally inactive heterochromatin. Recognition of methylated CpG by methylated DNA binding proteins, the MBD family, the Kaiso zinc finger family and the SRA domain proteins results in deacetylation and methylation of histone side chains through the recruitment of HDAC and HMT enzymes. Methylation of DNA is a heritable process ensuring Methylation dependant transcriptional repression is passed from mother to daughter cell during replication. Some of the proteins involved in this chromatin remodelling, MBD1, DNMT1, MLL, and CFP1 contain CXXC domains. hMBD1 contains 2 or 3 CXXC domains depending on the splice variant, with only the third CXXC domain shown to bind CpG dinucleotides. This thesis describes the work done to elucidate the structure of hMBD1 CXXC1 and to investigate hMBD1 CXXC12 di-domain by NMR spectroscopy and biochemical characterisation. The hMBD1 CXXC1 & CXXC12 domains were successfully over expressed in E. coli and purified. Unlabelled and uniformly 15N labelled proteins were produced for nuclear magnetic resonance (NMR) studies. Assignment of NMR spectra was carried out and constraints generated enabling structure determination of hMBD1 CXXC1 and to investigate the relationship between CXXC1 and CXXC2 of hMBD1. The solution structure of hMBD1 CXXC1 determined here was compared to the previously determined solution structure of hMLL CXXC in order to investigate their differences in DNA binding. NOE data from hMBD1 CXXC1 and CXXC12 are compared in order to investigate the domain structure of CXXC12. DNA titration of hMBD1 CXXC1 showed no significant interaction with a single CpG oligo while the loop region of hMBD1 CXXC1 differs significant in both structure and surface charge suggesting the loop region to be important for DNA binding. The recorded NOE data of hMBD CXXC12 suggests the two CXXC domains form a globular rather than a linear structure

Résumé :
Non-covalent interactions taking place in solution are essential in chemical and biological systems. The solvent environment plays an important role in determining the geometry and stability of interactions. This thesis examines aromatic stacking interactions, alkyl-alkyl interactions, edge-to-face aromatic interactions, halogen bonds and hydrogen…hydrogen interactions in solution. Chapter 1 briefly introduces the different classes of non-covalent interactions, in addition to the state-of-the-art models and methods for investigating these weak interactions. The chapter finishes with a focus on dispersion interaction in alkanes and arenes. Chapter 2 investigates dispersion interactions between stacked aromatics in solution using a new class of complexes and thermodynamic double mutant cycles (DMCs). In extended aromatics, dispersion was detected as providing a small but significant contribution to the overall stacking free energies. Chapter 3 concerns the experimental measurement of alkyl-alkyl dispersion interactions in a wide range of solvents using Wilcox torsion balances. The contribution of dispersion interactions to alkyl-alkyl association was shown to be very small, with DMC, QSPR method and Hunter's solvation model. Chapter 4 studies edge-to-face aromatic interactions in series of solvents. In the open system, edge-to-face aromatic interactions were found to be sensitive to the solvent environment. The solvent effects were complicated and cannot be rationalised by a single parameter. Further analysis is needed. Chapter 5 describes a preliminary approach to investigate organic halogen…π interactions in solution using supramolecular complexes and torsion balances. Chapter 6 is a preliminary investigation of the ability of hydrogen atoms to act as H bond acceptors in silane compounds. Computations and 1H NMR demonstrated a weak interaction between silane and perfluoro-tert-butanol.

Résumé :
This document is a project document based on finding a more economical way to use buttermilk at Synlait Milk Ltd. Buttermilk is a by-product from the Anhydrous Milk Fat (AMF), which is the concentration of cream. It is a problem for many dairy companies in New Zealand, including Synlait. the problems arise due to the opportunity cost of using it. It is a low value product, but made in substantial quantities at a ratio of 55% buttermilk to 45% AMF. This feasibility study contains an analysis on buttermilk at Synlait, including opportunity costs and benefits with processing buttermilk into buttermilk powder. It provides insight into the feasibility of implementing a ‘washed cream’ process at Synlait which would provide an alternative method for using buttermilk. The feasibility of separating buttermilk components for separate use is also examined. Overall, this project provides a more economical solution for buttermilk use at Synlait Milk Ltd.

In this creative project, I propose that comics can be used fruitfully to introduce undergraduates to the image-word dynamic, helping them become betters critics, more thoughtful consumers, and more effective creators of images. In addition, I argue that such a course of study be housed in an undergraduate rhetoric and composition major. Therefore, this project accomplishes three goals: it explores the rhetorical function of comics; second, it justifies the inclusion of comics in an undergraduate rhetoric-composition program; and, third, it provides a master syllabus for four classes that would provide the experience necessary to students wishing to study visual, verbal, and visual-verbal rhetorics.

In today's world of integrating voice, video and data into a single network, Asynchronous Transfer Mode (ATM) networks have become prevalent in the Department of Defense. The Department of Defense's critical data will have to pass through public networks, which causes concern for security. This study presents an efficient solution aimed at authenticating communications over public ATM networks. The authenticating device, Stargate, utilizes a high speed, low level authentication protocol that offers the low cost, flexibility, and extensibility of software, while still capable of yielding performance comparable to hardware based authentication.

Agena, Sabine Martina. « Modelling of protein solution properties ». Thesis, University College London (University of London), 1997. http://discovery.ucl.ac.uk/1317807/.

Texte intégral
Résumé :
The research pursued in this work concentrates on modelling two protein solution properties: activity coefficients and solubility. While modelling protein solubility was the prime objective activity coefficients were considered first as deviation from ideal solution behaviour was expected to occur for protein containing systems. Activity coefficients of protein related compounds, amino acids and peptides, were studied first hypothesising that these compounds represent proteins and because activity coefficient data is documented for those compounds but not for proteins. The predictive UNIFAC model was studied but failed, which led to examination of the related UNIQUAC model. The objective of the work was the creation of a model base, which was achieved. This model base was then utilised for protein containing systems. Protein activity coefficient data was made available and could be successfully modelled using the established framework. Furthermore, the activity coefficient data was examined over different pH and temperature ranges, salt types and concentrations. A qualitative comparison of the data to protein solubility results of other researchers was pursued and used to confirm the model approach. Having demonstrated that protein solubility was qualitatively represented through protein activity coefficients a quantitative solubility approach was addressed next. For two protein systems the solubility behaviour was modelled successfully as a function of salt concentration and temperature. Findings of other researchers were integrated into the discussion of the model results while also the calculated protein activity coefficients were examined and a qualitative confirmation of the model was achieved. The models used in this study for the description of two protein solution properties, when applied to six different proteins over various pH and temperature ranges, salt types and concentrations showed qualitative and quantitative success. They should find application to many other protein systems.

Résumé :
The factors limiting the performance of computer software periodically undergo sudden shifts, resulting from technological progress, and these shifts can have profound implications for the design of high performance codes. At the present time, the speed with which hardware can execute a single stream of instructions has reached a plateau. It is now the number of instruction streams that may be executed concurrently which underpins estimates of compute power, and with this change, a critical limitation on the performance of software has come to be the degree to which it can be parallelised. The research in this thesis is concerned with the means by which codes for linear programming may be adapted to this new hardware. For the most part, it is codes implementing the simplex method which will be discussed, though these have typically lower performance for single solves than those implementing interior point methods. However, the ability of the simplex method to rapidly re-solve a problem makes it at present indispensable as a subroutine for mixed integer programming. The long history of the simplex method as a practical technique, with applications in many industries and government, has led to such codes reaching a great level of sophistication. It would be unexpected in a research project such as this one to match the performance of top commercial codes with many years of development behind them. The simplex codes described in this thesis are, however, able to solve real problems of small to moderate size, rather than being confined to random or otherwise artificially generated instances. The remainder of this thesis is structured as follows. The rest of this chapter gives a brief overview of the essential elements of modern parallel hardware and of the linear programming problem. Both the simplex method and interior point methods are discussed, along with some of the key algorithmic enhancements required for such systems to solve real-world problems. Some background on the parallelisation of both types of code is given. The next chapter describes two standard simplex codes designed to exploit the current generation of hardware. i6 is a parallel standard simplex solver capable of being applied to a range of real problems, and showing exceptional performance for dense, square programs. i8 is also a parallel, standard simplex solver, but now implemented for graphics processing units (GPUs).

Résumé :
The aim of the work in this thesis is to push the technology of solution-processed semiconductor lasers beyond the state-of-the-art and bring it closer to real-world implementation. An emphasis is put on the demonstration of mechanically-flexible lasers having low thresholds, high photostability and potential for cost-effectiveness and compact integration. Different gain materials, designs and pump sources are used to improve the performance and capabilities of these lasers. Distributed feedback resonators are chosen due to their planar fabrication and their potential for lower threshold than other cavities in the case of solution-processed lasers. Two types of gain materials are used: organic semiconductors and colloidal quantum dots. Encapsulation schemes compatible with the mechanical flexibility of the final devices, e.g. using transparent polymers or flexible glass membranes, are proposed and studied in order to extend the operational lifetime of the devices. One highlight of this work is the development of, to our knowledge, the first diode-pumped, mechanically flexible organic lasers encapsulated with thin-glass for high photostability. Other important outcomes include mechanical wavelength tuning of lasers, record performance for colloidal quantum dot lasers optically-pumped in the nanosecond regime and the demonstration of a red/green/blue laser. The capability for sensing applications of some reported formats of lasers are also shown.

Examensarbetet är utfört i samarbete med Scania CV AB och är en del av masterutbildningen Teknisk Design på Kungliga Tekniska Högskolan, Stockholm, under 2014. Arbetet har fokus på de interiöra solskydden i Scanias lastbilar.Målet med examensarbetet var dels att kartlägga när, var och på vilket sätt solbländning är ett problem för lastbilschaufförer, dels att ta fram ett koncept som utgår från detta arbete.Scania är en välkänd lastbilstillverkare som profilerar sig med hög kvalitet. Fordonen anses tillhöra toppskiktet av lastbilar vad gäller tillförlitlighet och förarmiljö. De solskydd som är monterade i Scaniahytterna idag är traditionella, liknande de som återfinns i personbilar. Intervjuer och observationer av förare visade på stora svårigheter att nå passagerarskyddet från förarplatsen; många tvingas lätta från sin stol för att nå och detta påverkar trafiksäkerheten.Projektet gjorde initialt en kartläggning över var forskningen står i fråga om metoder för att mäta bländning och om detta kan appliceras på arbetet inom Scania. Slutsatsen är att man i stort inte skulle gynnas av att anamma denna typ av metoder. Uppmätningar av lastbilar och konkurrenters fordon gjordes för att förtydliga dagens läge med avseende på solskydd och samtidigt utveckla ett förslag till metod som skulle kunna användas långsiktigt.Utifrån insamlad kunskap utvecklades konceptinriktningar som testades mot förare i form av prototyper. Två koncept jämfördes i ett slutligt användartest i en lastbilshytt.Det slutgiltiga konceptet består av ett förarsolskydd samt ett passagerarsolskydd, precis som tidigare, men med den stora skillnaden att dessa kan sammankopplas. Föraren behöver inte utsätta sig och andra för risker, utan kan enkelt koppla ihop de två och fälla ner. Det finns ett på/av-läge i förarskyddet vilket gör att det är valfritt när de ska vara ihopkopplade eller inte. Passagerarskyddet styrs med förarskyddet och kan därför låsas i flera olika lägen för att skydda mot bländning. Inuti båda solskydden finns en förlängande del som kan dras ned med hjälp av ett handtag. Det är också ställbart i olika höjder.
This Master of Science thesis work is written in Stockholm 2014 in collaboration with Scania CV AB and as a part of the Technical Design Master education at Royal Institute of Technology. The project focuses on interior sun visors in Scania trucks.The objective of the thesis work was divided into two parts; to map when, how and in what way sun glare becomes a problem to truck drivers and also develop a concept that solves those problems.Scania is a well-known manufacturer of trucks and has a profile that stands for high quality. The trucks produced by Scania are considered to be among the best regarding reliability and driver environment. Today, the sun visors that are mounted in Scania cabs are traditional and similar to the ones in cars. A result from interviews with, and observations of, drivers showed that there are difficulties when it comes to activating the passenger visor. To be able to reach the visor on the passenger’s side, many drivers are forced to stand up from the seat, something that jeopardises traffic safety.Initially, a mapping of research reports that have been made about sun glare measuring methods was made. The question was whether the work at Scania would benefit from these methods or not. The conclusion is that, in large context, this probably would not be the case. Measurements of trucks and competitor vehicles were made in order to clarify and map the different sun glare solutions that exist today. This was also a way to develop a suggestion for future measuring methods.From the knowledge gathered, several concepts of various kinds were developed. Selected concepts were prototyped and evaluated by drivers. Finally two concepts were mounted in an actual cab and compared by users. This led to the final concept choice.The final concept consists of a parted sun visor, as before, but with the difference that these parts can be coupled. The driver no longer needs to endanger him/herself and others when activating the sun visor, since they can easily be connected and folded down. There is an on/off mode at the driver’s visor that allows the driver to decide whether the visors should be attached or not. Inside both visors is an extended part that can be pulled down and placed in different positions to fully cover the driver vertically.
