SCARFONE, ILARIA GIUSY. "Spatial control of mitotic exit and spindle positioning in budding yeast." Doctoral thesis, Università degli Studi di Milano-Bicocca, 2015. http://hdl.handle.net/10281/75407.

Abstract:
The asymmetrically dividing yeast S. cerevisiae assembles a bipolar spindle well after establishing the future site of cell division (i.e. the bud neck) and the division axis (i.e. the mother-bud axis). A surveillance mechanism called spindle position checkpoint (SPOC) delays mitotic exit and cytokinesis until the spindle is properly positioned relative to the mother-bud axis, thereby ensuring the correct ploidy of the progeny. SPOC relies on the heterodimeric GTPase-activating protein Bub2/Bfa1 that inhibits the small GTPase Tem1, in turn essential for activating the mitotic exit network (MEN) kinase cascade and cytokinesis. The Bub2/Bfa1 GAP and the Tem1 GTPase form a complex at spindle poles that undergoes a remarkable asymmetry during mitosis when the spindle is properly positioned, with the complex accumulating on the bud-directed spindle pole. In contrast, the complex remains symmetrically localized on both poles of misaligned spindles. The mechanism driving asymmetry of Bub2/Bfa1/Tem1 in mitosis is unclear. Furthermore, whether asymmetry is involved in timely mitotic exit is controversial. We investigated the mechanism by which the GAP Bub2/Bfa1 controls GTP hydrolysis on Tem1 and generated a series of mutants leading to constitutive Tem1 activation. These mutants are SPOC-defective and invariably lead to symmetrical localization of Bub2/Bfa1/Tem1 at spindle poles, indicating that GTP hydrolysis is essential for asymmetry. Constitutive tethering of Bub2 or Bfa1 to both spindle poles impairs SPOC response but does not impair mitotic exit. Rather, it facilitates mitotic exit of MEN mutants, likely by increasing the residence time of Tem1 at spindle poles where it gets active. Surprisingly, all mutant or chimeric proteins leading to symmetrical localization of Bub2/Bfa1/Tem1 lead to increased symmetry at spindle poles of the Kar9 protein that mediates spindle positioning and cause spindle misalignment. Thus, asymmetry of the Bub2/Bfa1/Tem1 complex is crucial to control Kar9 distribution and spindle positioning during mitosis.

Abstract:

The main objective of this thesis is to study how the structures of a sell dialog, via a web shop, should be designed in order to support and inspire the customer. To get the answer to this question I use a qualitative and quantitative method. The qualitative method is applied in connection with different interviews. The quantitative method is used to analyze different answers given from those who are interviewed. I also use the deductive method due to my interest of studying how reality can relate to the theories with the choice of the subject.

Moreover, this thesis is structured by three main perspectives; company, customers and techniques. The theoretical part of the thesis includes definitions and theories about electronic business, customers’ behaviour and technique, UML (Unified Modelling Language), which is a visual syntax for visualising, specifying, constructing and documenting system engineering, and UP (Unified Process), which is a method that complements UML. Furthermore, the empirical part of the thesis includes interviews with Chris Jangelöv and Patrik Cardell (Visma Spcs), who are representing the companys’ perspective on a sell dialog via a web shop. For the customers’ perspective on the subject, I collect and outline the interviews from Visma Spcs customers. Moreover, I review the interview with David Nadel, where he discusses the UML and UP techniques and also electronic business in general.

As for the results, I come to the conclusion that a web shop should be structured from a customer´s perspective and his/her inquiries concerning the products and services. UML and UP, however, are techniques that focus on the structuring of data and processes without taking the developing dialogue with the customer into serious account. These techniques do not address issues of why a web shop is used as it is, UML and UP only apply what a web shop can look like and how it could be used. Therefore, I argue that there is a lack of connection between the UML and UP techniques and the real live user and actual use. I also reached the conclusion that there should be three main building blocks when structuring a sell dialog via a web shop. These are; structure, information and navigation.

Abstract:
En central stabsprodukt i Svensk planerings- och ledningsmetod (SPL) är operationsdesign. Den traditionella operationsdesignen har kritiserats för sin linjäritet, stelbenthet och positiva progression och därmed ansetts mindre lämplig för operationer med defensiv inriktning eller stor osäkerhet. SPL, med målsättningen att vara en allomfattande planeringsmetod, har därför i 2017 års version bland annat tillförts ytterligare tre typer av operationsdesign. Denna uppsats undersöker hur SPLs typer av operationsdesign omhändertar tre defensiva operationsplaner från 1979. Undersökningen sker genom att en kvalitativ textanalys leder fram till efterhandskonstruktioner av planernas operationsdesigner. Denna följs av en kvalitativ innehållsanalys för att se hur dessa operationsdesigner omhändertar försvararens möjlighet att avgöra, undvika ett avgörande samt dennes behov av flexibilitet. Resultatet visar att alla designtyper fungerar väl när ett avgörande söks men sämre när ett avgörande försöker undvikas. Behovet av flexibilitet omhändertas bäst i den dynamiska designtypen och någorlunda väl i den traditionella. Båda har dock svårigheter i övergången till det militära slutläget om ambitionen i målsättningarna sänks. De två designtyperna tematisk och mixad, som främst är ämnade för mycket osäkra situationer, omhändertar däremot dåligt de planer som undersökts då mycket av den operativa inriktningen går förlorad. Sammantaget visar undersökningen att genom tillförsel av de nya designtyperna är SPL en bit på vägen mot en allomfattande planeringsmetod, men svårigheten att applicera stabsverktyget operationsdesign på defensiva operationer är ännu inte helt löst.

The concern with beauty and well-being was practically a female exclusivity until recently. The emergence of administrative positions that require social skilled and good looking men, to deal with customers and suppliers has made these professionals began to realize that a well-groomed image could help them to grow within companies and even raise their salaries. Then, beauty and wellness services for the male audience, began being offered although in a timid and restricted basis. This market grew slowly until the 90s, when some men began to assume more openly this vanity. The metrosexual term was coined to refer to men more concerned with beauty than the average. The fact is that nowadays, even men who do not consider themselves metrosexuals, are more beauty conscious and became the new patrons of spaces for personal care. This study analyzes men perception of spas, and check if the structure of these establishments is prepared to receive this consumer appropriately and with hospitality. In the research, a group of 119 men were interviewed and 3 spas in the city of São Paulo were studied. The results show that these establishments are well prepared to receive the male audience and that men gradually cease to be sporadic customers to become spas customers, using, in particular, well-being the services.
A preocupação com a beleza e bem estar foi praticamente uma exclusividade feminina, até recentemente. O surgimento de cargos administrativos que passaram a exigir dos homens, até então trabalhadores braçais em sua maioria, que demostrassem traquejo social e boa aparência para lidar com clientes e fornecedores fez com que estes profissionais começassem a perceber que uma imagem bem cuidada poderia ajuda-los a crescer dentro das empresas e até mesmo elevar seus salários. Teve início então, o consumo de serviços de beleza e bem estar por parte do público masculino, ainda que de forma tímida e restrita. Este interesse foi crescendo aos poucos, até que na década de 90, uma parcela dos homens passou a assumir mais declaradamente esta vaidade, surgindo, inclusive, o termo metrossexual para designar os homens mais preocupados com a beleza que a média. O fato é, que atualmente, mesmo os homens que não se consideram metrossexuais estão mais vaidosos e passaram a ser os novos frequentadores de espaços de cuidados pessoais. Este estudo analisa a visão dos homens sobre os spas, e observar se a estrutura destes estabelecimentos está preparara para receber este consumidor de forma hospitaleira e adequada. Para isto, 119 homens foram entrevistados e 3 spas na cidade de São Paulo visitados. Os resultados deste estudo mostram que estes estabelecimentos estão muito bem preparados para receber o público masculino e que os homens aos poucos, deixam de ser clientes esporádicos para tornarem-se clientes usuais dos spas, incorporando em especial os serviços de bem-estar ao seu dia a dia.

Neste trabalho apresenta-se um sistema de apoio à decisão (SAD) para planejamento de recursos de saúde. O Sistema de Planejamento dos Recursos da Saúde (SPRS), baseia-se em um modelo espacial de divisão territorial e alocação de demandas por serviços de saúde a centros de serviço, de forma a minimizar custos de transporte (generalizados). O sistema foi concebido para ajudar planejadores e tomadores de decisão em tarefas como localização, escolhas tecnológicas, determinação de capacidades de novos centros , assim como de centros já existentes. Adicionalmente, pode-se usar o sistema para analisar especificidades relativas a atendimentos de determinados segmentos como o do idoso, de crianças, etc. Em geral os beneficios oferecidos pelo sistema residem em sua capacidade informacional e em sua facilidade de uso. O SAD desenvolvido foi validado em estudo de caso, na qual o sistema foi utilizado por tomadores de decisão de três cidades do sul do Brasil. Em geral eles têm encontrado um grande valor, preenchendo a necessidade dos planejadores da saúde.
In this work we present a decision support system (DSS) applied to health care planning. The Health Care Planning System ("Sistema de Planejamento dos Recursos da Saúde" - SPRS) is based upon a spatial model of territorial division and assignement of demands for health services to service centers, in order to minimize total transportation costs (generalized). The system is designed to help planners and decision makers in tasks such as location, technological choices and capacity of new facilites, as well as old oves. In addition, one can use it to analize the economics of specific services to be offered, such as special care to the elder, children, etc. In general, the benefits offered by the system rely on its informational capability and easiness of use. The DSS developed was validated in a case study, in which the system was used by decision makers of three cities of southern Brazil. In general they have found it of great value fulfilling a need among health care planners.

Abstract:
This thesis offers a new approach to the study of long eighteenth-century watering places that combines the precise study of locality with a careful consideration of motivation. Looking at spas and seaside resorts in Kent between 1660 and 1820, the county hierarchy of watering places will be used to argue for the complexity and diversity of the visitor experience. The aim, therefore, will not be to offer a traditional narrative of resort development. Instead, it will explore the use of spas and seaside resorts across a wide range of intersecting axes, focusing on the social, cultural and medical aspects of resort life and considering in particular Margate and Tunbridge Wells as urban and leisure centres. Comparing resorts with national, regional and local catchment areas and exploring the development of watering places across time and between resort typologies, this thesis will look at Kent’s spas and seaside resorts as marriage markets, feminine arenas, centres for polite society, and places in which to be seen indulging in fashionable leisure and pleasure, showing how they reacted to and actively influenced a changing social order. Challenging portrayals of the water cure as an excuse used to justify the pursuit of pleasure and drawing on emerging discourses on fashionable illness, this thesis will argue for the importance of mineral and sea waters as a medical treatment during a period when few effective medicines existed that could treat the vast majority of afflictions. Thus by combining the study of locality with a recognition of the diversity of the visitor experience, this thesis will show how Kent’s watering places not only played an important role as social, cultural and medical arenas but also how they helped visitors navigate some of the most important areas of their lives.

Abstract:

Målet med vårt examensarbete har varit att på uppdrag från United Computer Systems skapa ett program som kopplar samman Visma SPCS och MS Outlook. Anledningen till detta program har varit att utöka den begränsade kontakthanteringen som finns i Visma SPCS. I större affärssystem blir det allt vanligare att så kallade CRM system integreras. Dock saknas oftast bra kontakthantering i lösningar som riktar sig till mindre företag. Genom att koppla samman SPCS med Outlook, ger det användaren möjligheter att lagra mer djupgående information om kunder, deras kontaktpersoner och leveransadresser.

Programmet har utformats i Borland Delphi och vi beskriver i denna rapport hur vi gått till väga för att skapa ett program som uppfyller vår uppdragsgivares önskemål vad gäller användbarhet och användarvänlighet.

Vi beskriver även några av de grundläggande begreppen för vårt projekt, så som Screen scraping och API för SPCS och Windows.

Abstract:

 

Det statistiska kvalitetsverktyget Statistisk Processtyrning, SPS, introducerades på BT Products AB i Mjölby utifrån en specifik implementeringsprocess. Introduktionen utfördes i en målningsprocess och genom detta arbete kunde aktuell process utvärderas och orsaker bakom eventuell urskiljbar variation eftersökas. I gällande process målas gods till eldrivna truckar svarta genom elektrostatisk pulvermålning, där eftersträvad färgskikttjocklek är 70 µm. Målningen utförs automatiserat av fyra robotar och för att erhålla kunskap om processens uppförande studerades och analyserades utfallet statistiskt utifrån en bestämd kvalitetsindikator, färgskikttjockleken. Data samlades in utifrån denna indikator genom kontinuerlig mätning på utvalt objekt och med hjälp av en mätmall för att erhålla jämförbara observationer. Tillförlitligheten hos insamlad data analyserades och observationerna uppvisade en normalfördelning och slumpmässighet. En hög grad av autokorrelation sågs dock, varför transformation av data krävdes innan fortsatta studier kunde utföras. I och med denna transformation erhölls oberoende och därmed tillförlitliga residualer, vilka studerades i styrdiagram för att information om processens uppförande över tiden skulle erhållas. Observationerna är individuella och anges som variabeldata, varför stora skiftningar i processen studerades i x‑ och MR-diagram och små skiftningar i EWMA-diagram. Vid studie av dessa diagram kunde såväl alarm som trender identifieras och processen ansågs därmed vara instabil. Dessa företeelser antogs vara resultatet av urskiljbar variation, orsakad av kontrollerbara faktorer. I den efterföljande processutvärderingen kom därför arbetet att fokusera på identifikation av dessa faktorer. För denna identifikation sattes en fokusgrupp samman, vilka listade möjliga faktorer i ett Ishikawadiagram utifrån de sju M:en.

Uppkomna faktorer testades utifrån främst tre olika metoder; tvåfaktorförsök, enfaktorförsök och loggning. Faktorförsöken genomfördes genom målning av testplåtar, där skillnad i färgskikttjocklek beroende på vald faktornivå studerades. Loggning av faktorer utfördes parallellt med produktion, varpå dessa värden ställdes mot registrerade värden på färgskikttjockleken i en ANOVA- eller korrelationsanalys. Utifrån resultatet av dessa tester delades undersökta faktorer in i Signifikanta, Delvis signifikanta, Eventuellt signifikanta och Ej signifikanta. De faktorer som ansågs vara signifikanta är Fluidisering och Pulverbatch, vilka kan vara bidragande orsaker bakom den urskiljbara variationen som identifierats. Fluidiseringen har periodvis varit undermålig i ett av de pulverkök som förser robotarna med pulver, något som kan förklara uppvisad låg korrelation mellan robotarna och den höga nivå av autokorrelation som skådats. Vid ett test med fyra olika säckar från två olika batcher sågs även en varierad batchhärkomst påverka resultatet, med en skillnad i färgskikttjocklek på mellan 10 och 20 µm på testplåten. De Delvis signifikanta faktorerna, så som injektorplugg, elektrod och munstycken, kan påverka utfallet vid en hög grad av förslitning och troligen fås störst inverkan i de fall då dessa samverkar. Genom att utföra rekommenderade åtgärder beträffande de signifikanta faktorerna, med avseende på att minska variationen, kan processen åter studeras och utredas. Beroende på utfall kan en stabil process förbättras och i annat fall söks nya källor till variation.

 


 

The statistical quality tool Statistical Process Control (SPC) was introduced at BT Products AB in Mjölby following the process of SPC implementation. The current process is a powder coating process where parts for powered trucks are painted black. The electrostatic powder coating is performed by four automatized robots and the desired layer thickness is 70 µm. The process has been evaluated from a quality characteristic, specified as the layer thickness, and special causes behind variation were identified. Data has been collected continuously from the process by measuring objects in the production, using a self-developed measurement template to receive comparable data. Statistical tools have been used to evaluate whether the data were reliable or not. A normal probability plot confirmed that the observations were normally distributed and a scatter plot established randomness. Autocorrelation was detected and the data had to be transformed, why the independent and reliable residuals were used in the subsequent analysis. Control charts were used to study the process over time, where individual x- and MR-charts detected large shifts in the process, while EWMA-charts detected small shifts. Alarms, trends and abnormal patterns were identified in these control charts, which led to the conclusion that the process could be considered out of control. The special causes behind this variation were assumed to stem from controllable factors and the work was therefore focused on identifying these special causes.

Factors were listed in an Ishikawadiagram by a focus group and tested using mainly three different methods. Design of experiments was used to test a two factorial design, and single factors were tested by one-factor-tests. A sheet metal was painted in both test methods and the difference in layer thickness, dependent on chosen level of the factor, was studied. Other factors were logged parallel to the production. Additional observations were compared to the registered layer thickness on parts and the relation analysed using ANOVA- or correlation analyses. Examined factors from these tests were divided and categorized into Significant, Partially significant, Possibly significant and Not significant. Fluidisation and powder batch were identified as significant factors and thereby possible causes behind the identified variation. The fluidisation in one of the powder containers has at times been misbegotten, something that can explain the high level of autocorrelation and the low level of correlation between the robots. When testing the batches, four sacks from two different batches were used and a large difference in layer thickness was observed depending on powder origin. A high degree of wear of the partially significant factors, as injector nozzle, electrode and gun nozzle, could affect the result, but they likely have the largest impact when collaborating. By performing recommended actions, in an attempt to reduce the variation on the basis of the significant factors, the process once again can be studied and evaluated. Depending on the result, a stable process can be improved, alternatively, new sources behind variation identified.

Abstract:
In this paper we have researched two methods for peptide synthesis; solid phase peptide synthesis (SPPS) and recombinant protein production, hereafter called recombinant production. The goal was to create a decision support that can be of use when choosing a production method for a given peptide. Additionally, we wanted to find a way to tell if a given sequence might be difficult to synthesize with SPPS, and in those cases recommend recombinant production as an alternative. To accomplish this, we have investigated general problems that may occur for the two methods as well as amino acid and sequence specific issues. We have also researched if there are any known solutions to avoid these problems, and by evaluating the gravity and frequency of the problems, with these solutions in mind, the decision support was created. A description of each considered issue is given, but the amount of each amino acid and the sequence of the amino acids in the peptide also needs to be considered when choosing the method. For 15 out of the 20 individual amino acids we have recommended the use of SPPS. For the remaining five, three are dependent on the placement within the sequence and in two cases we recommend considering recombinant production. We believe we have created a decision support that fulfills its purpose and can be of use when choosing the production method for future biotherapeutics.

Abstract:
Mestrado em Engenharia e Gestão Industrial
O presente relatório descreve um projeto desenvolvido ao longo de oito meses na empresa Bi-silque SPGS, S.A.. Trata-se de uma empresa que possui como principal ativo produtos de comunicação visual, sendo uma das mais conceituadas no contexto industrial em que está inserida. O reconhecimento por parte dos mercados faz com que o número de encomendas e a diversidade de produtos desejados tenham apresentado um crescimento exponencial ao longo dos últimos anos. Nesse sentido, o desafio proposto dividiu-se em dois grandes objetivos: por um lado, o aumento da produtividade de uma das linhas de embalagem mais importantes da organização; por outro lado, a diminuição do tempo de setup de uma linha das linhas de montagem. Em relação ao primeiro objetivo, houve uma preocupação prévia em estabilizar o processo em apreciação para que, em seguida, fosse possível a elaboração de um balanceamento das tarefas afetas a cada operador alocado. Como resultado final, registou-se um acréscimo de aproximadamente 43% no seu output. Já em relação ao segundo objetivo, para se reduzir o tempo despendido na troca de ferramentas, recorreu-se à aplicação da metodologia SMED (Single Minute Exchange of Die), resultando da mesma uma redução de cerca de 45% no tempo de setup da máquina-alvo.
This report arises from a project developed in eight months, in a company named Bi-silque SGPS, S.A. The core business of Bi-silque is a range of products related with visual communication and in its business area is one of the most recognized companies. The recognition given by the markets led to a exponential growth of the number of orders and a wider range of products demanded by consumers in recent years. Accordingly to that, the proposed challenge was divided in two objectives: on the one hand, the productivity increase of one packaging line, which is one of the most important lines of the organization; on the other hand, the time reduction related to a setup time of one assembly line. Regarding the first objective, the first concern was the process stabilization, to make possible the balancing task of each operator. As final result, it was reached an output increase of 43% For the second objective, the methodology SMED (Single Minute Exchange of Die) was applied, with a 45% setup time reduction.

Abstract:
With thorough literature studies as well as simulations, a way to minimize the exposure to radiationthat astronauts are at risk of encountering during a solar proton event is sought. The understanding ofwhere these particles come from, as well as the random nature of solar particle events is of importancein order to predict their occurrence. Different models used for predicting solar particle events based on aPoisson possibility distribution are presented, as well as real-time forecasts which give a warning of anapproaching event. Although the models used for real-time forecasts have a high accuracy rate, the averagewarning time is only approximately one hour. The downside with the predicted possible occurrence isthat this only gives a statistical probability of events that could possibly occur. For the real-time forecaststhe downside is that with an average warning time of only one hour, they do not give a lot of time forseeking shelter during the onset of an event. With simulations it is shown that the best way to minimizethe radiation dose obtained by astronauts is to use different materials of shielding. It is also shown that alower shielding thickness when encountering SPEs, for example when in a space suit, is useful as longas the total amount of time spent in this suit during the duration of a mission is planned thoroughly inorder to stay below the radiation dose limits. If an astronaut would be caught in an event with the samemagnitude and intensity as the solar particle event of August 1972, it is shown that the astronaut onlyhas nine minutes to seek shelter before exceeding the radiation dose limits and thereby risking radiationinduced sickness.
Med djupgående litteraturstudier, samt simuleringar, undersöks möjligheten att minimera den strålningsdossom astronauter riskerar att utsättas för under en protonstorm från solen. Förståelse för varifråndessa laddade partiklar kommer, och även deras slumpmässiga beteende, är av vikt för att kunna förutspådessa fenomen. Diverse modeller som används för att förutsäga hur dessa solstormar sannolikt kommerinträffa i framtiden, tillsammans med modeller som presenterar en prognos i realtid, diskuteras. Även omde tillgängliga realtidsmodellerna har en hög noggrannhet, så är ändå varningstiden inför en solstorm imedel omkring endast en timme. Detta ger väldigt lite tid för att söka skydd om en protonstorm skulleinträffa. Nackdelen med de förutsägelser som bygger på sannolikhet är att det endast ger en indikationpå vad för slags protonstormar som skulle kunna inträffa. Med simuleringar visas att det bästa sättetatt minimera strålningsdosen är genom att använda olika material samt tjocklek för att skärma av ochskydda astronauten mot inkommande strålning. Simuleringarna visar även att ett tunnare skydd, somtex av en rymddräkt, kan vara användbart så länge den totala tiden som spenderas i strålningsmiljöplaneras varsamt och delas upp mellan olika skyddsmaterial. Detta för att ej överskrida gränsen föraccepterad strålningsdos. Slutligen visas även att en astronaut som befinner sig i en protonstorm medsamma intensitet som den protonstorm som inträffade i augusti 1972 endast har 9 minuter på sig att sökaskydd innan den accepterade dosen av strålning är överskriden och risken för akut strålningssjuka ökar.

Abstract:
We interpret theoretically electron pair data observed in Pb(158 AGeV)-Au collisions at the CERN SPS by considering the system as an evolving fireball with parameters fit to experimental observables. Dilepton production in the QGP phase is found via standard finite temperature field theory techniques where annihilating quarks have thermally generated effective masses. After the phase transition, contributions from rho and omega meson decays are found via from experimentally determined forward scattering amplitudes which account for the effects of emission from a medium with finite temperature and density. All results are folded with a model which considers bias created by the CERES detector's acceptance. Our calculations agree well with existing data dilepton production at low and intermediate invariant masses.
Nous interprétons les données expérimentales sur les paires de leptons mesurées dans les collisions Pb-Au à 158 AGeV, au SPS du CERN. Nous traitons l'évolution du système hadronique en considérant une modélisation thermodynamique ajustée aux observables asymptotiques. La production de leptons dans la phase du plasma quark-gluon est obtenue avec les techniques reconnues de la théorie des champs à température finie, où les quarks ont des masses thermiques non-nulles. Après la transition de phase, les contributions des désintégrations des mésons rho et omega sont évaluées en partant des amplitudes de diffusion vers l'avant, ce qui tient compte des effets de milieu. Tous nos résultats sont filtrés par l'acceptance du détecteur CERES. Nos calculs sont en accord avec les données mesurées sur la production de dileptons de petite et moyenne masses invariantes.

Abstract:
Titel: Investeringsprocessen hos ett IT-företag – en fallstudie av Visma Spcs AB Bakgrund: En strukturomvandling har ökat kraven på dagens företag, krav som rör kontinuerlig förnyelse och förbättring, något som fört med sig ökade investeringsbehov. En bransch som tydligt präglas av de nya omvärldsförhållanden som strukturomvandlingen fört med sig är IT-branschen, en relativt ny och kunskapsintensiv bransch där immateriella investeringar dominerar. Visma Spcs AB är ett Växjöbaserat IT-företag som genomför stora immateriella kapitalsatsningar, framförallt i produktutveckling och humankapital. Syfte: Syftet med studien är att kartlägga och analysera Visma Spcs investeringsprocess, med fokus på företagets immateriella investeringar, och att bidra med kunskap om problematiken kring hantering och beslutslogik gällande ett IT-företags investeringar. Metod: Uppsatsen är utformad som en kvalitativ fallstudie med Visma Spcs som fallföretag. Det empiriska underlaget för uppsatsen utgörs av semistrukturerade intervjuer med tre av företagets anställda, verksamma inom olika avdelningar på företaget. Resultat, slutsatser: Visma Spcs investeringsprocess består av fem stycken olika faser, nämligen initiering, informationsinsamling, utvärdering av alternativ, framdrivning mot beslut samt beslut. Investeringsprocessen liknar således tillverkande företags investeringsprocesser, dock särskiljer sig kunskapsföretaget Visma Spcs när det gäller investeringsrutiner och verktyg, vilka ej är formella och traditionella. Dessutom är Visma Spcs investeringshantering kostnadsinriktad, då i stort sätt samtliga immateriella investeringar behandlas som vilka omkostnader som helst. Detta får konsekvenser för företagets lönsamhet, vilken på kort sikt blir sämre. På lång sikt är dock dessa kapitalsatsningar nödvändiga för att företaget skall kunna förbli konkurrenskraftigt på den föränderliga IT-marknaden. Förslag till vidare forskning: Vi tycker det vore av intresse att kvantitativa studier genomfördes på kunskapsföretag för att då kunna dra mer generella slutsatser kring deras investeringshantering. Även ett IT-företag som ej är lika ekonomiskt lönsamt som Visma Spcs vore intressant att studera för att se om företagens hantering skiljer sig åt.

Abstract:
The Rosetta spacecraft is on route to rendezvous with the comet 67P/ Churyomov-Gerasimenko. One of the instruments onboard is the Langmuir probe instrument (LAP) developed by the Swedish Institute of Space Physics. The LAP includes two spherical probes used to measure a number of properties of the surrounding plasma. One measured property is the plasma density for which the spacecraft potential is a good proxy. By the determining the potential between spacecraft and Langmuir probe, the spacecraft potential can be measured. But such measurements are sometimes disturbed by the potential from the spacecraft itself, the influence from photoemitted electrons and the solar wind wake behind Rosetta. In order to correct for the errors caused by spacecraft-plasma interaction in the solar wind a model depending on the spacecraft (and Langmuir probe) orientation is developed. The data is obtained from three-dimensional simulations of Rosetta, with varying plasma parameters, using the software SPIS (Spacecraft Plasma Interaction System). Least squares fitting with a set of basis functions then provide the input for a parametric modelling. The developed model makes it possible to estimate the influence of each of the disturbing effects. The developed model gives good fits to data obtained in SPIS simulations. The two angular dependent factors, modelling perturbation on potential measurements caused by photoelectrons and wake effects, show errors below the 100 mV level in all cases. The model describing the influence from spacecraft potential is slightly less accurate, with errors at or below the 400 mV level in all relevant cases.

Abstract:
The code size of single page web applications are constantly growing which do have an negative effect on the load time. Previous research have shown that load time are important to users and that a slow application will lose potential customers even before it has loaded. In this paper three architecturally far-reaching techniques are measured to see how they can improve the load time and help to decide if an application should be built with one or more of the tested techniques which are HTTP2 push, Code Splitting and Isomorphism. The experiment shows that Isomorphism can provide a big improvement for the time to first paint and that Code Splitting can be a useful technique for large code bases on mobile phones.

Abstract Bachelor Thesis 15hp, Business Program, School of Business and Economics at Linnaeus University, Controller, 2FE20E, VT 2018 Title: Implementing a Strategic Change - A Case Study on Visma Spcs Authors: Philip Bergsteinsson, Christoffer Walfridson, Filip Öggesjö Examiner: Elin Funck Tutor: Anders Jerreling Background and problem: Strategy work is a process consisting of two parts, formulation and execution. Companies that execute a strategy change are facing major challenges. Business strategy studies have shown that companies do not achieve their full potential and that there are a number of difficulties in strategy execution. Purpose: The purpose of the essay is to test the model of strategy execution that Kaplan and Norton have created and how it’s followed in an active strategy change. The essay will provide insight into the pitfalls and obstacles of the strategy implementation. Method: The study that has been conducted is a case study of a qualitative nature. The empirical material has been collected by means of semi-structured interviews. Conclusion: Visma Spcs is in the middle of the Vision 2020 process, a strategy change started in 2016. During these years, they have been working hard to formulate, implement, communicate, and get employees to understand Vision 2020 in order for the entire organization to work towards the common goals. The study highlights a number of problems Visma Spcs has with the strategy change, some are part of communication and knowledge about the strategy others are how to work with the process. Kaplan and Norton have created a process in six steps for strategy implementation, a process that, according to the purpose of the paper, is tested in this study. There have been identified some similarities with Visma Spcs strategy implementation and the theory, but also a number of deviations. The main points of the paper's conclusion are that Visma Spcs needs to work more with communication and feedback around Vision 2020.

Företag som genomför en strategiförändring står inför stora utmaningar. Studier inom företagsstrategi har visat att företag inte uppnår sin fulla potential och att det finns en rad hinder och svårigheter vid strategigenomförande. Syfte: Uppsatsens syfte är att testa den modell för strategigenomförande som Kaplan och Norton har skapat samt hur den efterföljs i en aktiv strategiförändring. Uppsatsen ska vidare bidra med insikt i strategigenomförandets fallgropar och hinder. Metod: Studien som genomförts är en fallstudie av kvalitativ karaktär. Det empiriska materialet har samlats in med hjälp av semistrukturerade intervjuer. Slutsats: Visma Spcs är mitt uppe i processen Vision 2020, en strategiförändring som tog fart 2016. De har under dessa åren arbetat flitigt med att formulera, implementera, kommunicera och få medarbetare att förstå Vision 2020 för att hela organisationen ska arbeta mot de gemensamma målen. Studien visar och belyser ett antal problem Visma Spcs har med strategiförändringen, några är en del av kommunikation och kännedom kring strategin andra är hur man arbetat med processen. Kaplan och Norton har skapat en process i sex steg för strategigenomförande, en process som enligt uppsatsens syfte testas i den här studien. Det har identifierats en del likheter med Visma Spcs strategigenomförande och teorin men även en hel del avvikelser. De viktigaste punkterna i uppsatsens slutsats är att Visma Spcs behöver arbeta mer med kommunikation och återkoppling kring Vision 2020.

Abstract:
L'objectif de cette thèse a été l'évaluation de deux semi-conducteurs (l'InP :Fe et le SPS :Te) comme matériaux pour les télécommunications optiques aux longueurs d'ondes infrarouges.
D'abord, en ce qui concerne l'InP :Fe: nous avons fait une caractérisation systématique du phénomène d'autofocalisation photoréfractive, prenant en compte les paramètres les plus importants qui intervient dans ce phénomène (température, dopage, intensité du faisceau et de l'éclairage de fond, polarisation du faisceau). Ainsi, nous sommes maintenant capables de contrôler le phénomène d'autofocalisation. En tenant compte également des temps de réponse mesurés et des simulations réalisées, nous croyons que l'interaction de deux faisceaux autofocalisés est possible et maîtrisable sur une échelle de temps de l'ordre de microsecondes. Néanmoins, alors que nous connaissons l'influence des paramètres mis en jeu sur l'autofocalisation, le développement d'un modèle théorique reste indispensable pour une compréhension des mécanismes physiques qui déterminent la dynamique de l'autofocalisation photoréfractive. Nos mesures expérimentales et simulations théoriques ont montré que les modèles existants ne décrivent pas d'une manière satisfaisante les phénomènes observés dans InP :Fe.
En revanche, l'autofocalisation observée dans le SPS :Te est décrite par les modèles "classiques" existants. On peut dire que ce deux matériaux sont complémentaires: alors que dans le SPS :Te l'autofocalisation est plus lente que dans l'InPFe, elle est plus forte et plus facile à maîtriser. Tenant compte de cette remarque, nous croyons que ces deux matériaux trouveront leur place dans de futures applications.

Abstract:
Les travaux présents ici portent sur l’étude et la prospection de matériaux ferroiques. Cette étude consiste en une approche revêtant plusieurs aspects que sont la chimie du solide, la physique du solide et la science des matériaux. Deux parties sont développées, avec deux approches différentes. La première se concentre sur les liens entre composition/structure/propriétés dans des matériaux de la famille des TTB dérives de Ba2NdFeNb4O15 à travers l’étude de solutions solides à base de Li et l’étude de l’impact des différents paramètres de synthèse sur la nature de l’anomalie diélectrique mesurées sur pastilles densifiées. La mise en évidence de modulation structurale dans cette famille de matériaux semble être en lien direct avec l’observation des variations de propriétés diélectriques. L’utilisation de diffraction électronique notamment permet la mise en évidence de ces modulations structurales et leur évolution en température. Dans une seconde partie, l’approche consiste à utiliser le Spark Plasma Sintering (SPS) comme technique de densification pour des matériaux dits “fragiles” mais aussi d’explorer des propriétés diélectriques jusqu’alors inaccessibles, sur matériaux massifs. Le développement de la technique SPS à basse température permet ainsi non seulement de densifier à basse température des matériaux fragiles, mais aussi d’obtenir des phases inaccessibles dans des conditions de températures similaires par traitement thermique conventionnel. De même, l’obtention de céramique moléculaire de très haute densité a pu être réalisée, malgré des températures de décomposition extrêmement faible (100 ˚C)
The present work focuses on the prospection and understanding study of ferroic materials. It consists in a multiple aspect approach, including materials chemistry, materials physics and materials processing. Two parts compose this work, with two different approaches. The first one focuses on the links between composition, structure and properties in materials belonging to the TTB family, more specifically derived from Ba2NdFeNb4O15, through the exploration of Li containing solid solutions, and the impact of synthesis parameters on measured dielectric anomalies on dense samples. The observation of structural modulation in these materials seems to be closely related to the observation of dielectric anomalies variations. Using electron diffraction techniques allowed the evidence of such anomalies and the following of their thermal evolution. In a second part, the approach consists in using Spark Plasma Sintering (SPS) as a densification technique for so called “fragile” materials but also explore dielectric properties impossible to experimentally measure thus far. Developing low temperature SPS technique not only allows to densify ceramics at low temperatures fragile materials, but also to obtain inaccessible phases in similar temperature conditions using conventional thermal treatments. Moreover, sintering of molecular ceramic at very high density was possible, even if its decomposition temperature is extremely low (100 ˚C)

Abstract:
The quasicrystals are characterized by unusual rotational symmetries that are not observed in the crystalline materials, which is the cause of their interesting material properties. Because of that a particular attention was paid to quasicrystalline structures in the literature research. The research also contains a description of electron beam technology, spark plasma sintering method and introduction to the problematics of wear. As the default materials for the experimental part were selected Titanium Grade 2 powder and Cristome A5 powder which was partially composed of quasicrystalline phase. The first series of samples was sintered only from powder Cristome A5. The second series was sintered from the mixture of 80 % Titanium Grade 2 powder and 20 % Cristome A5 powder. For the compaction of samples spark plasma sintering technology was selected. Samples were then systematically modified by electron beam and subjected to pin on disc tests. Samples modified at 750 °C had the best wear resistance. Samples modified at 1150 °C contained increased amount of quasicrystalline phase.

This academic research, as a master level work, aims to verify the present value of Pastoral Constitution Gaudium et Spes. It is due to the interest that Vatican Council II keeps causing, after so many years. The social-religious situation has changed. Therefore, a lucid and profound reanalysis is needed. In order to do so, using the theological method, we did a historical analysis of its antecedents, pointing the specific occasion in which this important document was published. Then, pointing out the document s guide-lines related to the recent Church Teaching announcements: Document of Aparecida (2007) and the Benedict XVI s Encyclic, Caritas in Veritate (2009). We have placed all these documents in its historical context, allowing the dialogue with Gaudium et Spes. The conclusion is that, after almost fifty years, Gaudium et Spes still fits nowadays reality and can be used as base to theological-pastoral reflection
Este trabalho acadêmico, em nível de mestrado, tem como objetivo principal verificar a atualidade da Constituição Pastoral Gaudium et Spes. Isto se justifica pelo interesse que o Concílio Vaticano II continua exercendo, após tantos anos. Mas a situação sócio-eclesial mudou. Por isso, uma releitura lúcida e aprofundada se faz necessária. Utilizando o método teológico, fazemos uma análise histórica dos antecedentes, indicando a ocasião em que foi promulgado este importante documento. Em seguida, pontuamos as linhas-mestras do documento em questão com recentes manifestações do Magistério da Igreja: o Documento de Aparecida (2007) e a Encíclica de Bento XVI, Caritas in Veritate (2009). Situamos todos estes documentos em seu contexto histórico, possibilitando o contra-ponto com a Gaudium et Spes. A conclusão é que, passados quase cinquenta anos, a Gaudium et Spes ainda reserva surpreendente atualidade e pode servir como base para a reflexão teológico-pastoral

Abstract:
My diploma thesis focuses on the comparison of possibilities of the statistical software SAS and SPSS in the area of the factor and cluster analysis and the multidimensional scaling. They deal with the methods for identifying groups of the similar statistical values (variables). The ascertained relations among the variables can serve to decrease the proportion vectors of the variables, which describe the individual monitored objects (statistical units), which helps us to apply other various methods, for example the regression or discriminant analysis. By one of the ways for finding the similarity of variables in the cluster analysis or the multidimensional scaling is searching for their relations. Whereas the base of the factor analysis is the formulation of the relation between two variables by means of the covariances, eventually Pearson correlation coefficient, it is possible to use also coefficients of correlation for the cluster analysis and the multidimensional scaling, in some case other measures. The thesis describes mainly the command syntax of the procedures implemented in SAS and SPSS. The meaning of the individual parametres and the partial specifications of each command are explained. The results gained by various types of analyses are compared on the basis of the real dataset. The possibilities of the statistical software SAS and SPSS are evaluated in the conclusion and it is referred to their advantages or disadvantages. The attention is also paid, for example, to the form of the input dataset, to the quaility of outputs or to the partial methods.

Abstract:
Throughout the last century, theoretical and experimental research made by the international nuclear physicists community has led to important advancement in the knowledge of the mechanisms that govern the behavior and stability of the nuclei. The technological improvements necessary to support this research has often opened the way to new applications in other field of science and industry which directly reflects in our common life experience. Nowadays, Europe is becoming more and more a leader in both theoretical and experimental nuclear physics, as testified by the presence on its territory of several institutes and laboratories dedicated to this field of research, like CERN (Organisation Européenne pour la Recherche Nucléaire), the world’s largest particle physics laboratory. Italy, represented mainly by INFN (Istituto Nazionale di Fisica Nucleare), is one of the main members of this community. One of the most important projects supported by INFN is SPES (Selective Production of Exotic Species), which aim is to develop a facility for the production of radioactive ion beams (RIBs) in one of the four national laboratories of INFN, LNL (Laboratori Nazionali di Legnaro). The facility is designed to produce and deliver to users both proton-rich and neutron-rich nuclei (range of mass 80-160 amu) to be used for nuclear physics research, as well as other applications in different fields of science. The generation of the aforementioned isotopes will occur inside a properly designed target, which represents the core of the whole project. The choice of the proper material for the target, both in terms of composition and properties, is of vital importance in determining the quantity and type of the produced isotopes. In this work, the synthesis and characterization of different types of target materials are presented. The results of experimental tests performed on some of the produced materials, in configurations very similar to those intended for the final SPES facility are also reported. Chapter 1 gives a general overview of the SPES project and its context whereas chapter 2 introduces the main topics related to the on-line behavior of the SPES target, relative to both its layout and to the properties of the material constituting it. Chapter 3 is focused on uranium carbide, which will be used at SPES to produce neutron-rich isotopes; after a description of its main physicochemical properties, the results of two on-line tests performed on target prototypes made of this material is reported and discussed into detail. In chapter 4 the synthesis methods and release-related properties of two potential materials to be used as SPES targets for the production of proton-rich isotopes, boron and lanthanum carbides, are presented
Nel corso dell’ultimo secolo, la ricerca teorica e sperimentale condotta dalla comunità internazionale in fisica nucleare ha portato ad importanti passi avanti nella comprensione dei meccanismi che governano il comportamento dei nuclei e della loro stabilità. In molti casi, le innovazioni tecnologiche che si sono rese necessarie per supportare tali ricerche hanno aperto la strada verso nuove applicazioni scientifiche ed industriali con ripercussioni dirette nella vita di tutti i giorni. Attualmente, l’Europa è sempre più leader nel campo della fisica nucleare, teorica e sperimentale, come testimoniato dalla presenza nel suo territorio di svariati istituti e laboratori dedicati a questa specifica area di ricerca, come ad esempio il CERN (Organisation Européenne pour la Recherche Nucléaire), il più grande laboratorio al mondo per la fisica delle particelle. L’Italia, principalmente rappresentata dall’INFN (Istituto Nazionale di Fisica Nucleare), è uno dei principali membri di questa comunità. Uno dei progetti più importanti finanziato dall’INFN è SPES (Selective Production of Exotic Species), la cui finalità è la costruzione di una facility per la produzione di fasci di ioni radioattivi, in uno dei quattro laboratori nazionali dell’INFN, LNL (Laboratori Nazionali di Legnaro). La facility è progettata per produrre e fornire agli utenti isotopi proton-rich e neutron-rich (massa compresa fra 80 e 160 amu) utilizzabili per esperimenti di fisica nucleare, ma anche per altre applicazioni in diversi settori scientifici. La formazione di tali isotopi avverrà all’interno di uno specifico bersaglio (target), che rappresenta il cuore dell’intero progetto. La scelta dell’opportuno materiale per il target, sia in termini di composizione che di proprietà è di vitale importanza nel determinare la quantità e tipo di isotopi prodotti. In questo lavoro, vengono descritte nel dettaglio la sintesi e caratterizzazione di diversi tipi di materiali proposti come target, ed inoltre vengono riportati i risultati di test sperimentali condotti su alcuni di essi, ottenuti in modalità molto simili a quelle a cui saranno sottoposti nella facility SPES. Il capitolo 1 fornisce una presentazione generale del progetto SPES e del contesto scientifico ad esso legato, mentre nel capitolo 2 viene descritto nel dettaglio il comportamento operativo del target SPES, con particolare riferimento alla sua geometria e alle proprietà del materiale che lo costituirà. Nel capitolo 3 vengono presentate le proprietà del materiale scelto come bersaglio per produrre isotopi neutron-rich, ovvero il carburo di uranio; vengono inoltre presentati i risultati di un test sperimentale di produzione di isotopi da parte di un prototipo di target SPES costituito di tale materiale. Il capitolo 4 descrive la sintesi e caratterizzazione di carburi di boro e lantanio, con particolare riferimento alle proprietà riconducibili alla capacità di rilascio di isotopi; tali materiali rappresentano dei potenziali target SPES per la produzione di isotopi proton-rich

Abstract:
The structure of matter and the fundamental lows of nature have always marked the interest of the nuclear physics community, especially in the understanding of the atomic nucleus stability. The knowledge of how the fundamental particles behave is besides leading a strong development of applied science, with the consequent improvement or invention of useful technologies in industry, medicine and scientific research. European Council for Nuclear Research, CERN (Geneva – Swiss) is the most important nuclear physic laboratory, which houses the world’s largest and most complex scientific instruments devoted to these purposes. In Italy, from the mid-twentieth century and especially in the recent decades, the National Institute of Nuclear Physics (INFN) became one of the main members, participating with shared activities and offering new projects of interest. At Legnaro National Laboratory (INFN-LNL, Padua, Italy), the SPES project, ie Selective Production of Exotic Species, is the flagship of INFN under development and construction, which has the goal to produce pure radioactive ion beams in the neutron rich side of the so-called “valley of stability”. The construction of the SPES facility involves multidisciplinary teams and worldwide collaborations as the University of Padua (Italy), Laboratory for Emerging Nanometrology (LENA, Germany), Isotope Separator On Line Device project (ISOLDE-CERN, Swiss), Oak Ridge National Laboratory (ORNL, USA) and iThemba LAB (South Africa). The ion-sources dedicated to the production of Radioactive Ion Beams (RIB) have to be highly efficient, selective (to reduce the isobar contamination) and fast (to limit the decay losses of short-lived isotopes). For radioactive beam generation the source must operate steadily for extended periods of time at elevated temperatures (up to 2000°C). The selection of the most appropriate choice for the target/ion source is of paramount importance since its performance determines the intensity, the beam quality, and the number of radioactive beams that can be provided for experimental use. The world wide spread RIB facilities came up with a large variety of solutions to meet part or all of these requirements such as: surface, plasma, electron cyclotron resonance and laser ion-sources. The latter, which is based on the Resonant Laser Ionization (RLI) technique is fundamental in the ISOL facility due principally to the high ionization efficiency can be obtained and to the high mass-selectivity of the process. Its selectivity, namely the low production rate of unwanted species, is strongly affected by the surface ionization mechanism, which occurs since both laser and surface ion sources share same components where the ionization process takes place. The production of pure beams and the knowledge of its efficiency in the context of ISOL facilities, is the most important aspect on which the research activities are actually focused. For these reasons, the main goal of the work here presented was the development of a test bench, called Laser Front End, which allows estimating the ionization efficiency of the laser in absence of contaminants and thus providing essential information for the future on-line tests. Beside the Laser Front End, ancillary devices for its construction have been designed, developed, constructed and finally tested. Chapter 1 gives a general overview of the ISOL facilities, their applications and a general overview of the SPES project. Chapter 2 will present the design of the Laser Front End, with particular attention to the Knudsen cell design aimed to estimate the laser ionization efficiency. Then, in Chapter 3, the re-design of the quadrupole triplet for the ion beam transport will be provided, whereas in Chapter 4 the preliminary design of both vacuum and gas recovery systems are described. Finally, Chapter 5 provides the study, the test and the re-design of a commercial flexible transmission joint on which fatigue failure occurred despite compliance with installation recommendations had been assured.
La struttura della materia e più in generale le leggi fisiche che governano l’universo hanno sempre attirato l’attenzione da parte della comunità scientifica nell’ambito della fisica nucleare, soprattutto per quanto riguarda la struttura del nucleo atomico. La ricerca in questo ambito scientifico ha portato a forti sviluppi nella scienza applicata e nelle tecnologie utilizzate in ambito industriale e medico. Uno dei laboratori più importanti a livello mondiale è il CERN (Ginevra-Svizzera), il quale ospita uno dei più complessi apparati scientifici per la ricerca in questo settore. Negli ultimi decenni in Italia, l’Istituto Nazionale di Fisica Nucleare (INFN), ha partecipato nella condivisione e nello sviluppo congiunto di attività di ricerca che hanno portato alla nascita di nuovi progetti. In particolare, a Legnaro (Padova-Italia), il progetto SPES (Selective Production of Exotic Species) propone lo sviluppo di dispositivi per la produzione selettiva di faci di ioni radioattivi cosiddetti neutron rich. La costruzione della facility, che costituirà l’insieme delle apparecchiature per concretizzare il progetto in questione, coinvolge molteplici gruppi di lavoro, ognuno con competenze disciplinari molto diverse fra loro e coinvolge più enti e istituzioni come l’Università degli Studi di Padova (Italia), il Laboratory for Emerging Nanometrology (LENA, Germany), Isoltope Separation On Line Device project (ISOLDE-CERN, Svizzera), Oak Ridge National Laboratory (ORNL, USA) e iThemba LAB (Sud Africa) Le sorgenti di ionizzazione per la produzione di fasci di ioni esotici (RIBs) devono essere caratterizzate da alta efficienza e selettività. Le sorgenti in questione devono altresì operare ad una temperatura stabile di circa 2000°C. Il complesso camera target accoppiato alla sorgente di ionizzazione opportuna determina l’intensità, ovvero il numero di particelle che si riescono ad ionizzare, e la qualità del fascio prodotto. A tal fine, in molte facility, sono molte le sorgenti di ionizzazioni usate per raggiungere tale scopo: le più comuni sono la sorgente di ionizzazione superficiale, la sorgente al plasma e la sorgente laser. Quest’ultima, basata sul metodo di ionizzazione RILIS (Resonant Laser Ionization technique) è quella che garantisce elevata efficienza di produzione ed elevata selettività. La selettività della sorgente laser, ovvero la capacità di non ionizzare specie atomiche indesiderate, è influenzata dalla ionizzazione superficiale. Ciò avviene dal momento che alcuni componenti di cui tale sorgente è costituita, una volta portati ad elevate temperature, possono ionizzare superficialmente alcune specie atomiche del primo e secondo gruppo della tavola periodica. Questo lavoro si concentra sullo sviluppo di un apparato sperimentale (Laser Front End) che permette di stimare l’efficienza di ionizzazione laser in assenza di contaminanti dovuti ad altri meccanismi di ionizzazione, fornendo così informazioni importanti per il funzionamento della facility. Oltre al Laser Front End, dispositivi ancillari sono stati sviluppati, costruiti e testati. Il Capitolo 1 fornisce informazioni generali sulle facility di tipo ISOL, le loro applicazioni e una panoramica del progetto SPES. Il Capitolo 2 descrive le fasi progettuali del Laser Front End, con particolare attenzione alla cella di Knudsen. Il Capitolo 3, verrà presentato lo sviluppo e la riprogettazione del tripletto di quadrupoli elettrostatico, essenziale per focalizzare i fasci di ioni. Nel Capitolo 4, è descritta la progettazione e lo sviluppo del sistema da vuoto e infine il sistema di recupero dei gas radioattivi. In conclusione, nel Capitolo 5 sono descritte le fasi relative alla riprogettazione di un giunto flessibile, la cui rottura a fatica è stata osservata in condizioni di funzionamento nominali.

Abstract:
Detta examensarbete utförs i samarbete med företaget Järn AB, vilket är ett svenskt företag med gjuteri, pulvermetallurgi samt bearbetningsverksamhet. Produkterna är av varierande typ, storlek och volym, avsedd för ett brett kundsegment däribland fordonsindustrin samt maskintillverkare. Företaget har mer än 500 anställda och namnet Järn AB är fiktivt. Syftet med arbetet är att föreslå ett angreppssätt för hur Järn AB kan gå vidare med statistisk processtyrning (SPS). Detta angreppssätt ska baseras på erfarenheter från fordonsindustrin samt litteraturstudier. Studien kommer grunda sig utifrån perspektiven människa, teknik och organisation. Resultatet kommer även utmynna i ett praktiskt förslag som ger företaget konkreta exempel kring införandet av SPS. Förslagen i studien kommer grunda sig på fyra studiebesök som valts ut under arbetets gång. Tre av de valda företagen är framstående i kvalitetsfrågor inom svensk industri och det fjärde företaget jobbar med statistisk processtyrning i stor utsträckning. De besökta företagen har olika typer av processer, däribland gjuteri- och bearbetningsprocesser som också återfinns hos uppdragsgivaren. Det har också utförts en nulägesbeskrivning hos Järn AB för att se vilka möjligheter det finns med statistisk processtyrning och jämföra utgångsläget med studieobjekten.  Resultatet av studiebesöken gav att inget av de svenska företagen använde SPS i dagsläget även om vissa hade erfarenheter från ett tidigare användande och flera såg framtida möjligheter med SPS. Om personalen involveras i SPS-arbetet och får ansvaret för detta arbete så kommer det ge ökad motivation och större chans att skapa ett långsiktigt arbete. Det förutsätter att systemet är lättanvänt samt att användaren har fått rätt utbildning i området. Det är också viktigt att det går att justera en parameter i processen som är direkt kopplad till utfallet av SPS. De processer som visat sig lämpliga för SPS hos Järn AB är de bearbetningsprocesserna som inte är självjusterande. Gjuteri- och pulverpressning är relativt komplexa processer som gör det svårt att knyta specifika parametrar till utfallet och behöver mer utredning innan SPS kan införas. De styrdiagram som har visat sig lämpliga utifrån process- och hårdvarutekniska aspekter är R-diagram då dessa lämpar sig vid införandet av SPS på variabeldata och har stöd i föreslagen mjukvara. Vid ett senare skede är det också värt att titta på andra typer av styrdiagram som EWMA och CUSUM.

Abstract:
L’observation d’états CHI du charmonium en hadro-production, nécessite une résolution très fine pour séparer des états de masses très proches (45 MeV entre deux états CHI de masse supérieure à 3510 MeV). L’expérience WA11 a pu séparer les états CHI(3510) et CHI(3555), mesurer leur section efficace en production π – bérylium à 185 GeV / c et chiffrer la contribution de ces états à la production du J /ψ (17,7 % et 12,8 % ). L’étude détaillée qui a été menée sur les événements CHI(3555) n’est pratiquement produit que par fusion gluon – gluon, alors que le CHI(3510) est issu également des fusions quark – antiquark légers et gluon – gluon. Il se trouve que les différents graphes envisageables, tant en conservation de couleur qu’en évaporation de couleur, semblent contribuer à la production d’états de charmonium, dans des rapports simples donnés par des règles de comptage (∝s², ∝s³,…etc. ). A partir de nos données, à 185 GeV /c, et en utilisant des fonctions de structure usuelles (par exemple, celles de DUKE – OWENS), on peut alors calculer les caractéristiques de la π – production des J/ψ, des CHI ₁ et des CHI ₂, à d’autres énergies du S. P. S… Ces calculs donnent des résultats comparables aux observations des groupes « Ω » (pour le J/ψ) et « GAMS » (pour les CHI) réalisées vers 40 GeV/c
The observation of hadroproduced charmonium CHI states requires a good resolution to disentangle states of similar masses (45 MeV of difference for masses larger than 3500 MeV). The WA11 experiment was able to distinguish the two CHI (3510) and CHI(3555) states, measure their cross – sections in π – beryllium at 185 GeV/c and give a ratio of contribution of this to J /ψ production (17,7 % and 12,8 % respectively). A refined analysis of CHI – states events has shown different processes the π – production of these states. At 185 GeV/c, the CHI (3555) comes mainly from gluon – gluon fusion, but the x(3510) is equally produced by quark – antiquark fusion and gluon – gluon fusion. One finds that different graphs can be envisaged, both in colour conservation as well as in colour evaporation, to contribute to charmonium state production given by simple counting rules (∝s², ∝s³,…etc. ). Using our data at 185 GeV/c and the usual structure function (like the DUKE – OWEN’s ones), we are able to compute the J/ ψ, CHI₁ and CHI ² π – production at any other S. P. S. Energy. This calculation gives values in agreement with results from the « Ω » group (for CHI), at GeV/c

Jedną z kluczowych sygnatur uwolnienia kwarków jest wzmocnienie dziwności, którą zawiera m.in. cząstka Λ. Bezpośrednia jej obserwacja, jako cząstki nienaładowanej elektrycznie, nie jest łatwa, jednakże jej ślad może być zrekonstruowany na podstawie analizy naładowanych produktów rozpadu. Głównym celem tej pracy jest obliczenie całkowitej i różniczkowych krotności cząstki Λ dla reakcji p(158 GeV/c)+p. W tym celu przygotowano i przetestowano procedurę służącą ekstrakcji cząstek Λ spośród danych zebranych przez NA61/SHINE w oddziaływaniach p+p w zakresie pędów akceleratora SPS.

Abstract:
This master´s thesis focuses on duplex microstructures preparation by powder metallurgy. A hybrid material can be created by combining two or more existing materials in different geometries, and thus the newly formed composite can provide a superposition of the properties of the starting materials (powders). This means that it will have an improved combination of the required properties. The theoretical part describes in detail the hybrid materials and the architectured materials that contain highly controlled structures. Structure control allows to change the variety of possible geometries and opens up a number of other useful properties. Therefore, this thesis also deals with the mechanical alloying and SPS. The experimental part describes procedures of preparation of four samples of composites with a duplex structure from a powder of a significantly tough alloy (austenitic steel 316L) in combination with a powder of a significantly strong alloy (titanium carbonitride). A crucial part of this thesis is characterization of these four samples by electron microscopy methods (SEM, TEM, EDS) and supported by hardness measuring.
