This thesis deals with the usage of optical signal in aircraft navigation systems. The solution is based upon the creation of runway identi cation system working with the record of an onboard camera.

Syftet med denna studie är att undersöka vilka metoder lärare tycker fungerar i undervisningen av elever med läs- och skrivproblematik och hur de motiverar dem i förhållande till forskningen. Detta undersökts genom intervjuer med lärare och specialpedagoger på mellanstadiet. Resultatet av studien visar på att det är lärarens kunskaper om olika metoder och strategier som avgör om undervisningen blir lyckad eller inte. Detta beror på att alla strategier och metoder inte passar alla elever direkt utan behöver anpassas och bytas ut allteftersom eleven utvecklas. Hela tiden ska fokus ligga på vad som fungerar bäst för eleven. Undervisningen ska anpassas efter elevens behov och inte tvärtom. Samtidigt är det många i studien som påpekar att de anpassningar som är bäst är de som kan appliceras på hela klassen och inte enbart är för en elev. Det här är någonting som lärarna och specialpedagogerna jag har intervjuat håller med om men samtidigt använder de endast en metod, Rydaholmsmetoden. / The purpose of this study is to investigate what methods teachers think work best in teaching pupils with reading and writing problems and place that in relation to the research. This was done through interviews with middle school teachers and special educators. The result of the study shows that it is the teacher's knowledge of different methods and strategies that determine whether the teaching is successful or not. This is because all strategies and methods do not fit all pupils directly, but need to be adapted and replaced as the pupils develops. All the time, the focus should be on what works best for the pupils. Teaching should be adapted to the needs of the pupils and not the other way around. At the same time, many in the study point out that the best adaptations are those that can be applied to the whole class and not just for one pupil. This is something that the teachers and special educators I interviewed agree with, however, they only use one method, the Rydaholms method.

Bakgrund: Privata företag förväntas ha färre finansieringsmöjligheter än publika börsnoterade företag, vilket gör privata företag mer begränsade till extern skuldfinansiering från kreditinstitut. Kostnaden för den externa skuldfinansieringen påverkas av kreditgivarens riskbedömning och det kontrollbehov som bland annat uppstår på grund av agentkonflikten mellan långivare och låntagare. Vi ämnar därför undersöka hur ägaren och ägarens val av styrelse och extern revisor kan reducera agentkonflikten och därmed reducera företagens räntekostnader vid extern skuldfinansiering. Syfte: Syftet med vår uppsats är att undersöka huruvida ägarkoncentrationen samt ägarens val av styrelse och extern revisor påverkar företagens externa räntekostnader i privata svenska aktiebolag. Metod: Studiens ansats är av deduktiv art utifrån en tvärsnittsdesign. Studien utgår från en kvantitativ metod för att testa studiens hypoteser utifrån ett urval av medelstora privata svenska aktiebolag. Resultat: Ägarkoncentrationen, styrelsens storlek samt styrelsens oberoende har ingen signifikant påverkan på räntekostnaden. Däremot visar resultaten i studien att det finns ett signifikant negativt samband mellan räntekostnaden och valet att utse en extern revisor från Big4. / Background: Private companies are expected to have fewer funding opportunities than public listed companies, which makes private companies more dependent on external debt financing from credit institutions. The cost of the external debt financing is affected by the lenders risk assessment and the need for control that naturally appears because of the agency conflict between lenders and borrowers. We aim to examine how the owner and the owner’s choice of board of directors and external auditor can reduce the agency conflict and thus reduce the companies interest costs in external debt financing. Purpose: The purpose of the study is to investigate if the owner concentration as well as the owner’s choice of board composition and external auditor, affects the external interest costs of private Swedish limited companies. Method: The study’s approach is deductive in nature and based on a cross sectional design. The study is based on a quantitative method for testing the hypotheses, based on selection of medium-sized private Swedish limited companies. Conclusions: The ownership concentration, the board size and the board independence have no significant influence on the interest rate. The study does however show a significant negative correlation between the interest rate and the choice to appoint an external auditor from one of the Big4.

Many students change their choice of secondary school programme or fail to complete their studies which results in a great cost to society or personal costs for the student. The purpose is to examine the experiences of two groups of upper secondary school students regarding their choice of upper secondary school programme. The questions we wanted answers to were: what influenced the student’s choice of study, what support did the students receive from comprehensive school and what might have caused them to choose another programme. The study was carried out in two focus groups where one of the groups was made up of students who had chosen the “right” programme and the other made up of students who had chosen the “wrong” programme. One thing that influenced the student’s choice of upper secondary school programme was whether or not the programme provided eligibility to higher studies which they had heard from primary school and parents was a choice that would give them many possibilities in the future. It appeared that there had not been much of a guidance process for developing career management skills which could have given the students support in reflecting over their transition to upper secondary school. The students’ interests and the parents and people near the students influenced the students’ choices. The study shows that students needed a longer guidance process and a clearer understanding of its purpose. Narrow and wide guidance varied depending on a student’s comprehensive school. They would have needed a better description of the consequences such as what study demands were required for the programme and what moving or commuting would mean in practice.

Ti-6Al-4V manufactured by electron beam melting Keywords: Additive manufacturing, high-temperature tensile properties, low cycle fatigue, neutron diffraction, fatigue crack growth ISBN: 978-91-89325-27-2 (Printed) 978-91-89325-26-5 (Electronic) Ti-6Al-4V is the most widely used α+β titanium alloy in aerospace engine applications due to its high specific strength. Typically, the alloy is manufactured as castings or forgings and then machined to final geometry. These conventional manufacturing processes do however generate a lot of waste material, whereas additive manufacturing (AM) can potentially produce a near-net-shape geometry directly from the feedstock. In the past decade, electron beam melting (EBM), one of the powder bed fusion techniques, has been widely researched to build Ti[1]6Al-4V components.

HIP treatment of conventionally cast Ti-6Al-4V is normally performed at 920 ˚C, 100 MPa for 2 hours. This same HIP treatment has then been adapted also for EBM-manufactured Ti-6Al-4V, which however results in coarsening of α laths and reduction of yield strength. Therefore, finding a more appropriate HIP treatment for this new type of Ti-6Al-4V material, i.e. EBM manufactured, would be of great benefit for the industry.

Lowering the HIP treatment temperature to 800 ˚C and increasing the pressure to 200 MPa has recently been proven to close the porosity to a high degree while sustaining the high yield strength. In this thesis, the high-temperature tensile properties of EBM-manufactured Ti[1]6Al-4V subjected to a low-temperature (800 ˚C) HIP treatment were evaluated and compared with standard HIP-treated (920 ˚C) materials. Metallurgical characterization of the as-built, HIP-treated materials have been carried out to understand the effect of temperature on the microstructures. The standard HIP[1]treated material measured about 1.4x - 1.7x wider α laths than those in the low[1]temperature HIP treated and as-built samples, respectively. The standard HIP[1]treated material showed about 10 - 14% lower yield strength than other HIP treated materials. At 350 ˚C the yield strength decreases to about 65% compared to the room temperature strength for all tested materials. An increase in ductility viii was observed at 150 ˚C compared to that at room temperature, but the ductility decreased between 150 - 350 ˚C because of activation of different slip systems. The low cycle fatigue (LCF) behavior of such a modified HIP (low-temperature HIP) material is assessed at two different strain levels and compared with the corresponding LCF properties for the standard HIP material. Even though the modified HIP material had lowest minimum life cycles to failure, the overall fatigue performance is comparable with that of the standard HIP material. Also, fatigue life predictions were made from the measured defect size at the crack initiation site using NASGRO. The calculated life predictions showed good agreement with the experimental values in most cases. In-situ neutron diffraction measurements on tensile test specimens were conducted, at both room temperature and at 350˚ C, for the standard and modified HIP-treated materials. The objective was to gain essential insights on how the crystal lattice strains relate to the macroscopic strengths in these specific microstructures. This investigation helped to understand the load partitioning between different slip planes and constituent phases in the microstructure at different temperatures. / Ti-6Al-4V är den mest använda α+β titanlegeringen i flygmotortillämpningar på grund av sin höga specifika hållfasthet. Vanligtvis tillverkas legeringen som gjutgods eller smide och bearbetas sedan till slutlig geometri. Dessa konventionella tillverkningsprocesser genererar dock en hel del avfallsmaterial, medan additiv tillverkning (AM) potentiellt kan producera en nästan slutgiltlig geometri direkt från råvaran. Under det senaste decenniet har elektronstrålesmältning (EBM), en av pulverbäddsfusionsteknikerna, undersökts mycket för att bygga Ti-6Al-4V-komponenter. Ändå kan det byggda materialet innehålla defekter såsom gasporer som kräver efterbearbetning, såsom varm isostatisk pressning (HIP) för att producera nästan helt täta komponenter. HIP[1]behandling av konventionellt gjutet Ti-6Al-4V utförs normalt vid 920 ˚C, 100 MPa under 2 timmar. Samma HIP-behandling har sedan anpassats även för EBM[1]tillverkat Ti-6Al-4V, vilket dock resulterar i förgrovning av α-lameller och minskning av sträckgränsen. Att hitta en mer lämplig HIP-behandling för denna nya typ av Ti-6Al-4V-material, dvs EBM-tillverkat, skulle därför vara till stor fördel för industrin. Att sänka HIP-behandlingstemperaturen till 800 ˚C och öka trycket till 200 MPa har nyligen visat sig stänga porositeten i hög grad samtidigt som den höga sträckgränsen bibehålls. Ti-6Al-4V används huvudsakligen i applikationer för flygmotorer upp till en maximal driftstemperatur på 300 ˚C. Därför studerades högtemperaturdragegenskaperna hos de olika HIP-behandlade EBM[1]byggmaterialen i detta forskningsarbete. Denna studie visade att duktiliteten påverkas av aktiveringen av olika glidsystem baserat på temperatur. Ytterligare neutrondiffraktionsexperiment utfördes tillsammans med in-situ dragprovning för att bestämma det aktiva glidsystemet vid en specifik temperatur. Utmattningsbeteendet hos det lågtemperaturbehandlade HIP-materialet utvärderas också genom lågcykelutmattningstestning och utmattningsspricktillväxttest. Utmattningsprestandan för det modifierade HIP[1]materialet utvärderades mot standard HIP- material och visade sig ha jämförbara utmattningsegenskaper. Förutsägelser om utmattningsliv utfördes med hjälp av vi programvaran NASGRO där livsförutsägelserna visade god överensstämmelse med experimentella livscykler i de flesta fall. / <p>Submitted papers or manuscripts have been excluded from the fulltext file.</p>

Purpose: this degree project will examine the possibilities of increasing the structural integrity in case of fire of a preexisting concrete building according to the rules in EKS 11, specifically for a hospital building. Furthermore, the degree project will provide solutions to increase the structural integrity in case of fire. Method: the study is based on a technical report provided by Kadesjös Ingenjörsbyrå AB where information about the hospital buildings technical aspects is presented. To examine current rules for fire-resistance rating of the hospital building, the regulations presented in BBR and EKS 11 were studied. Products had to fulfill the criteria of the European testing standards when they were evaluated as solutions that would increase the structural integrity of the building. The products were then evaluated according to the criteria presented in Eurocode 2 when dimensioning with tabulated data. An interview were held with Michael Försth professor in structural and fire engineering. Professor Försth were asked questions to evaluate potential methods and products that could increase the fire-resistance rating of the hospital building. Results: showed that proposed solutions are able to increase the structural integrity in case of fire of the hospital building to a degree where they were able to fulfill the requirements. Not all solutions were appliable on all building components of the hospital buildings. The difference in technical aspects of the solutions were presented. Conclusions: the identified solutions for increasing the structural integrity in case of fire are rock wool insulation, fire protection paint, additional concrete casting on columns and installation of sprinkler system. The solutions differ in technical aspects such as the space they take when implemented, weight increase when implemented, the amount they increase the structural integrity in case of fire when implemented and the method of implementing the solutions.

Gamla normer som kretsat kring kärlek och relationer har idag försvunnit och kärleken har, likt samhället, moderniserats. Relationer har blivit friare och partners har blivit utbytbara. Den känslomässiga investeringen har därmed kommit att bli svårare i moderna relationer. Men trots detta söker människor efter sin perfekta match och ett långvarigt förhållande. Gift vid första ögonkastet är ett samtida realityprogram där deltagare som längtar efter kärlek ska gifta sig med en främling. Programmet ger insyn i hur par, från att aldrig ha träffat varandra, ska gifta sig och under ett par veckor bo ihop som hustru och man. Under programmets gång ska de bygga en relation för att vid programmets slut bestämma om de vill vara fortsatt gifta eller om de ska skilja sig. För att se hur moderna relationer och känslomässig investering förmedlas i reality-TV utgår den här studien i observationer av det svenska och amerikanska Gift vid första ögonkastet. Studien visade att kärleken i Gift vid första ögonkastet utgjordes av ett stort frihetsbehov och att kommunikation både möjliggjorde och skapade problem för den känslomässiga investeringen. Det var när deltagarna visade att de var redo att släppa på delar av sin frihet och värderade tilltro till sin partner som det känslomässiga engagemanget kom att kommuniceras som allra tydligast. / Old norms that revolve around love and relationships have today disappeared and love has, like society, been modernized. Relationships have become freer and partners have become replaceable. The emotional investment has thus become more difficult in modern relationships. But despite this, people are looking for their perfect match and a long-lasting relationship. Married at First Sight is a contemporary reality show where participants who long for love are about to marry a stranger. The program provides insight into how couples, from never having met each other, gets married and live together as a wife and husband for a couple of weeks. During the program they will build a relationship so that they in the end of the program can decide whether they want to remain married or whether they want to divorce. To see how modern relationships and emotional investment are conveyed in reality TV, this study is based on observations of the Swedish and American Married at first sight. The study showed that love in Married at first sight consisted of a great need for freedom and that communication both enabled and created problems for the emotional investment. It was when the participants showed that they were ready to let go of parts of their freedom and valued trust in their partner that the emotional commitment came to be communicated most apparent.

Under våren 2020 konstaterades att coronaviruset Covid-19 är en pandemi. Detta medförde restriktioner inom skolvärlden som innebar en påtvingad förändring att bland annat studie- och yrkesvägledningen nu skulle ske digitalt. Med frågeställningarna ”Hur ser utvecklingen av den snäva och vida digitala vägledningen ut för studie- och yrkesvägledare inom gymnasieskolan”, ”Vilka för- och/eller nackdelar ser studie- och yrkesvägledare inom gymnasieskolan med digital vägledning?” samt ”Vilka önskemål finns hos studie- och yrkesvägledare inom gymnasieskolan kring eventuell kompetensutveckling när det gäller digital vägledning?” är vår förhoppning att vi ska uppnå studiens syfte. Syftet är att undersöka huruvida verksamma studie- och yrkesvägledare på kommunala gymnasieskolor i sju kommuner i norra Sverige anser sig besitta de kompetenser som behövs för att anpassa sig till ett eventuellt nytt arbetssätt med digital vägledning, samt om och i så fall hur detta har utvecklats i samband med Covid-19. En kvalitativ forskningsmetod med semistrukturerade intervjuer användes för insamling av data. Vi har analyserat resultatet med hjälp av karriärteorin Social Cognitive Career Theory (SCCT), och dess begrepp upplevd självförmåga, förväntat utfall och personliga mål. Av denna studie framgår att den snäva vägledningen fungerar relativt väl digitalt, medan den vida vägledningen upplevs som en utmaning. I resultaten lyfts fördelar med digital vägledning som effektivitet och tillgänglighet samt nackdelar som brist på personlig kontakt. Det framgår även att videosamtal föredras framför telefonsamtal bland de studie- och yrkesvägledare vi intervjuat, samt att efterfrågan på kompetensutveckling uppfattas som minimal. Framledes kan informanterna se att en kombination av traditionell och digital vägledning är att föredra, även när det blir möjligt att genomföra mer vägledning på plats. / In the spring of 2020, it was declared that the coronavirus Covid-19 is a pandemic. This led to restrictions in the school generally that meant a forced change that, among other things, career guidance would now take place digitally. With the questions ”What is the development of the narrow and wide digital guidance for career counsellors in upper secondary school?”, ”What advantages and/or disadvantages do career counsellors in upper secondary school see with digital guidance?” and ”What are the wishes of career counsellors in upper secondary school regarding possible competence development in digital guidance?” our hope is that we will achieve the purpose of the study. The aim is to investigate whether active career counsellors at municipal upper secondary schools in seven municipalities in northern Sweden consider themselves to possess the skills needed to adapt to a possible new way of working with digital guidance, and if so how this has developed in connection with Covid-19. A qualitative research method with semi- structured interviews was used for data collection. We have analyzed the results using Social Cognitive Career Theory (SCCT), and its concept of self efficacy, outcome expectations and personal goals. This study shows that the narrow guidance works relatively well digitally, while the wide guidance is perceived as a challenge. Our results highlights benefits of digital guidance such as efficiency and accessibility as well as disadvantages such as lack of personal contact. Other results indicates, among other things, that video calls are preferred to telephone calls by the career counsellors when it comes to career guidance, and that the demand for competence development is perceived as minimal. In the future, the informants can see that a combination of traditional and digital guidance is preferable, even when it becomes possible to implement more face-to- face guidance.

Bakgrund: LARO i Sverige är omgärdat av strikta regler. Läkemedlen som används, däribland buprenorfin, intas dagligen övervakat av sjuksköterska de tre första månaderna och vidare till dess att patienten bedöms kunna ta läkemedlet på egen hand. Sedan 2018 finns buprenorfin som depotinjektion veckovis eller månadsvis, vilket innebär en ny omvårdnadssituation. Syfte: Att utforska sjuksköterskans perspektiv på införandet av buprenorfin som depotinjektion i LARO. Metod: Tolv semistrukturerade intervjuer av sjuksköterskor med erfarenhet av depotinjektioner buprenorfin i LARO. Resultat: Införandet av depotinjektioner innebar ett fokusskifte i behandling och omvårdnad med bland annat minskad kontroll och ökad tillit mellan sjuksköterska och patient. Behandlingen med depotinjektioner ansågs kunna öppna för ökad egenmakt för patienterna. LARO-enheternas organisatoriska förutsättningar påverkade hur de tagit sig an den nya behandlingsformen. Kunskap och samsyn efterfrågades. Slutsats: Depotinjektioner buprenorfin kan öppna upp för nya sätt att främja egenmakt i LARO. Det finns ett behov av forskning på området. / Background: Opioid substitution treatment in Sweden is strictly regulated. Medications like Buprenorphine are taken daily supervised by a nurse during the initial three months and thereafter until the patient is assessed to be trusted with self-administration. Prolonged-release injectable Buprenorphine has beenavailable since 2018 for weekly or monthly use. This has implications for nursing care and practices. Purpose: To explore the nurse’s perspective on introducing prolonged-release injectable buprenorphine in opioid substitution treatment. Method: Twelve semi-structured interviews were conducted with nurses experienced in treatment with prolonged-release injectable buprenorphine. Results: The introduction of injection treatment entailed a shift in focus regarding restrains, trust and patient empowerment. The care units’ approaches to the new treatment differed and was influenced by organisational conditions. Nurses requested more knowledge and consensus about the new treatment. Conclusion:Prolonged-release injectable formulations may enable new approaches to patientempowerment in opioid substitution treatment. Research in this field is required.

The implementation of information systems creates risks for activities, which means that it is a key element in the survival of corporations. There are many studies on the very subject of the implementation of information systems, which deal with the same concepts such as the top management, visions and objectives, team, communication, training and change management. However, the problem that arises on the subject is that a large number of these implementations are still failing, either because the timetable is not met or because the financial expectations are exceeded. There is therefore a need to examine whether the results of studies and the way in which activities deal with implementation of information systems are consistent. The purpose of the study is therefore to examine whether there is a convergence of existing studies and the perspective of top management. The research question is used to answer the purpose: What successfactors does the top management perceive exist for an implementation, and how does it differ from previous research? To perform the investigation, six semi-structured interviews have been conducted with people in the top management who are performing implementations in a qualitative cross-sectional study. The persons have been chosen by a selective method and they are working in different places around Sweden. All persons have a long experience in implementation of information systems. 6 categories were identified from the theoretical framework of the study, and they were used to carry out a deductive and inductive thematic analysis of collected data. The study presented a few anomalies that exist when it comes to the knowledge of the information on the subject and the previous research that exists on the subject. The differences of previous research and the perception of information related to the field of communication were the field of communication. The information on means of communication and communication plans is referred to a great deal in the previous studies, while in the previous studies it is widely communicated within the project, where elements such as involvement, resistance and response are addressed. A new finding was presented, a new underlying factor for every factor. In addition to the model a new factor was added, agile. It showed that working agile was benefiting for the corporations. Rest of the factors were validated against the previous research and the importance of having the rest of the factors in the development proved to be important. / Vid implementering av informationssystem skapas risker för verksamheter, vilket betyder att genomförandet är en avgörande del för verksamhetens överlevnad. Det finns många studier inom just ämnet implementering av informationssystem, där några framgångsfaktorer förekommer oftare än andra, nämligen: ledning, visioner och mål, team, kommunikation, utbildning och förändringsledning. Problemet som dock uppstår inom ämnet är att det fortfarande är en stor mängd av implementeringar som misslyckas, antingen beroende på att tidsplaneringen inte uppfylls eller att budgetplaner överskrids. Det finns behov av att undersöka om en överensstämmelse av föregående studier och hur verksamheter behandlar implementeringar av informationssystem. Syftet med studien handlar om att undersöka om det existerar en överensstämmelse hos de befintliga studierna och verksamhetsledningens perspektiv. För att sedan besvara syftet används forskningsfrågan: Vilka framgångsfaktorer personer i verksamhetsledande roller upplever som viktiga för implementationen av informationssystem i sin verksamhet och vilka skillnader samt likheter som finns hos tidigare forskning? För att undersöka området så har sex semistrukturerade intervjuer genomförts med personer i ledningen hos verksamheter som bedriver implementeringar av informationssystem. Detta har sedan presenterats genom en kvalitativ tvärsnittsstudie. Personerna valdes ut genom en lämplig urvalsmetod och arbetar på olika platser runtom i Sverige. Samtliga personer har lång erfarenhet inom ämnet implementation. Sex kategorier togs fram utifrån studiens teoretiska ramverk, detta användes för att genomföra en deduktiv-induktiv tematisk analys av insamlad data. Studien presenterade ett fåtal avvikelser som existerar när det kommer till informanternas vetskap kring ämnet och den tidigare forskningen som existerar inom ämnet. De olikheter som tidigare forskning och informanternas uppfattning relaterade till var kommunikationsområdet. Där benämner informanterna mycket kring kommunikationsmedel samt kommunikationsplaner medan inom tidigare studier går de genom kommunikationen allmänt inom projektet, där delar som involvering, motstånd och bemötande behandlas. Samt att ett nytt fynd presenterades, att varenda faktor har en underliggande faktor. Dessutom så lades en ny faktor till: agilt tillvägagångssätt, då ett agilt tillvägagångssätt har visat sig främja arbetet. Resterande faktorer som presenterades validerades mot den föregående forskningen, där vikten av att faktorerna är med under en implementation är vital.
