Abstract:

The B0.2 V magnetic star τ Sco stands out from the larger population of massive OB stars due to its high X-ray activity, peculiar wind diagnostics and highly complex magnetic field. This Letter presents the discovery of the first two τ Sco analogues – HD 66665 and HD 63425, identified by the striking similarity of their ultraviolet (UV) spectra to that of τ Sco. ESPaDOnS spectropolarimetric observations were secured by the Magnetism in Massive Stars CFHT Large Program, in order to characterize the stellar and magnetic properties of these stars. cmfgen modelling of optical ESPaDOnS spectra and archived IUE UV spectra showed that these stars have stellar parameters similar to those of τ Sco. A magnetic field of similar surface strength is found on both stars, reinforcing the connection between the presence of a magnetic field and wind peculiarities. However, additional phase-resolved observations will be required in order to assess the potential complexity of the magnetic fields and verify if the wind anomalies are linked to this property.

Abstract:

In this work, I have studied whether if one can detect AD / HD in preschool. I have read some literature and searched on the Internet. I have also tried to get to interview people who are familiar with this topic, which has not been easy. I have questioned 13 persons if they would participate in an interview, but most have refused because they do not have time. I succeeded anyhow to get three persons, two special educators and a nurse on the BVC. Special Student teachers are working to put the various educational activities in the preschool / school when children are in need of assistance. Children nurse is working with children to look up at the controls as they come in and where they can see if there is something not as it should. The answer I came up with through the literature and interviews is that AD / HD is a neuro-psychiatric disability and is logically divided into three groups that they have to Impulsivity problems, over activity and attention problems. Special Student teachers tell of the symptoms / signs of AD / HD as the first notice are that the children with AD / HD have problems in concentrating in a task. What distinguishes boys from girls is that boys are more hyperactive and ports in more trouble than girls do. Girls are more reclusive and shy and have been easier to become depressed and anxious. It is difficult to detect AD / HD in preschool unless the kids have severe problems with attention, impulsivity and over activity

I also got answer to that one can detect AD / HD if you're looking for it, but it’s not the essential, the important is to support children with AD / HD in the learning and development. Special Student teachers talked a lot of work how to help children in preschool with various educational activities such as solid framework, transparency and daily schedules. They can also work in small groups but that is not always suitable for all children. Then we can bring the children who have problems at the front near the teacher in order to give praise and jacking.

Abstract:

Flickor med AD/HD upptäcks ofta inte i tid vilket kan ge konsekvenser inom flera områden under uppväxten. Syftet med denna uppsats var att bidra till en ökad förståelse kring hur diagnosen AD/HD kan påverka livet under uppväxten för flickor. Sex vuxna kvinnor med AD/HD intervjuades för denna studies syfte. Studien grundade sig i kvalitativ metod med hjälp av fenomenologisk tolkning samt meningskoncentrering vid sammanställning och analys av intervjumaterialet. Undersökningen fokuserade på sex centrala teman; diagnosens betydelse, skola, fritid, familjen, jämnåriga relationer och självuppfattning. Resultatet förtydligade att dessa centrala teman är betydelsefulla områden för en flicka med AD/HD under uppväxten. Ett fastställande av diagnosen AD/HD spelar en central roll gällande förståelse och hjälp från omgivningen. Studien visade på att flickor med AD/HD har vissa svårigheter i relationer till lärare, jämnåriga samt familj under uppväxten. För majoriteten av respondenterna har mamman varit det viktigaste stödet under uppväxten. Det har framkommit att familj och lärare har svårt att förstå samt att hantera flickor med AD/HD. Flickor med AD/HD har olika grad av svårigheter och tillgångar i skolarbetet samt i vardagen. I studien framgick det att undervisningsformen har betydelse för en flicka med AD/HD. Självuppfattningen hos en flicka med AD/HD kan påverkas av samhällets syn på hur en flicka ska vara. I studien framgick det tydligt att flertalet av respondenterna upplevt sig som en pojkflicka under uppväxten. Studien visade även på förekomst av psykisk ohälsa hos flickor med AD/HD under uppväxten.

Abstract:

Stellar flares are a frequent occurrence on young low-mass stars around which many detected exoplanets orbit. Flares are energetic, impulsive events, and their impact on exoplanetary atmospheres needs to be taken into account when interpreting transit observations. We have developed a model to describe the upper atmosphere of extrasolar giant planets (EGPs) orbiting flaring stars. The model simulates thermal escape from the upper atmospheres of close-in EGPs. Ionisation by solar radiation and electron impact is included and photo-chemical and diffusive transport processes are simulated. This model is used to study the effect of stellar flares from the solar-like G star HD 209458 and the young K star HD 189733 on their respective planets, HD 209458b and HD 189733b. The Sun is used as a proxy for HD 209458, and is an element of Eridani, as a proxy for HD 189733. A hypothetical HD 209458b-like planet orbiting the very active M star AU Microscopii is also simulated. We find that the neutral upper atmosphere of EGPs is not significantly affected by typical flares on HD 209458 and HD 189733. Therefore, stellar flares alone would not cause large enough changes in planetary mass loss to explain the variations in HD 189733b transit depth seen in previous studies, although we show that it may be possible that an extreme stellar proton event could result in the required mass loss. Our simulations do however reveal an enhancement in electron number density in the ionosphere of these planets, the peak of which is located in the layer where stellar X-rays are absorbed. Electron densities are found to reach 2.2 to 3.5 times pre-flare levels and enhanced electron densities last from about 3 to 10 h after the onset of the flare, depending on the composition of the ionospheric layer. The strength of the flare and the width of its spectral energy distribution affect the range of altitudes in the ionosphere that see enhancements in ionisation. A large broadband continuum component in the XUV portion of the flaring spectrum in very young flare stars, such as AU Mic, results in a broad range of altitudes a ff ected in planets orbiting this star. Indeed, as well as the X-ray absorption layer, the layer in which EUV photons are absorbed is also strongly enhanced.

Abstract:

Syftet med denna studie är att lyfta fram problematiken kring flickor med ADHD diagnos. Att utforska hur dessa kan upptäckas samt vilka tillvägagångssätt man kan använda sig som pedagog för att ge dem det stöd och hjälp de behöver. För att kunna belysa frågorna kring detta ämne genomfördes tre intervjuer med tre verksamma specialpedagoger. Intervjuerna tolkades med hjälp av kvalitativ metodik. Resultatet beskriver specialpedagogers syn på flickor med ADHD diagnos i skolan samt lyfter fram vilka metoder specialpedagoger använder sig utav för att ge dessa flickor det stöd de behöver. I resultatet framkommer att det inte är särskilt ovanligt att större delen av flickor med ADHD aldrig får någon diagnos. Forskningen inom ämnet är ännu otillräcklig. Lärare behöver mer kunskap för att kunna bistå flickorna och ge dem en bättre framtid. Det framkommer av resultatet att flickor med ADHD är svåra att upptäcka och att dessa behöver hjälp för att kunna utvecklas.

Abstract:

Under de senaste åren har de globala utsläpps standarder blivit mer stringenta när vi talar om Heavy Duty (HD) Dieselmotorer. Dessutom har varje region, eller land, sina egna regler med egna utsläppsnivåer för de huvudsakliga föroreningarna: CO, kolväten (HC), kväveoxider och partiklar (PM). Också, den verkliga användning, skiljer sig alltid från laboratorieförhållanden där motorerna testas för att klara lagkraven. För ett företag som Scania, som utvecklar och använder HD dieselmotorer och har ett intresse av att sälja sina produkter över hela världen, har olika utsläpps regler en direkt inverkan på den framtida produktutvecklingen. Dieselmotor utrustade HD lastbilar eller bussar kontinuerligt förbättras ständigt i syfte att uppfylla dessa lagkrav, antingen genom nya och komplexa motorkonstruktioner, förbränningskontrollstrategier eller avgasefterbehandlingssystem (t.ex. Catalyst, SCR, EGR, UDS, etc.). Men ingenting kan anpassa en dieselmotor för olika de bränsletyper som den kan träffa på under en resa från norra Sverige till södra Italien. Det är därför bränslekvalitet och bränslets egenskaper är viktiga aspekter när man talar om motorutveckling och utsläpp.Denna avhandling föreslår en rad svar om bränslekvalitets mätningar. Först föreslås definitioner för de viktigaste bränsleegenskaperna. Deras påverkan på drift och utsläpp diskuteras också. För det andra presenteras en översyn av de för närvarande tillgängliga teknikerna på marknaden för mätning ombord. Dessa tekniker kan mäta och upptäcka dessa bränsleegenskaper. De inbyggda teknikerna är tänkta att införliva samma mätteknik som ett laboratoriet som används för analys av bränsleparametrar, erbjuda jämförbara resultat, större rörlighet och fordonsanpassningsförmåga. Till sist, föreslår avhandlingen tre sensorer som innehåller två innovative ombord mätnings tekniker, som kan upptäcka bränslets egenskaper. Dessa sensorer är testade med olika typer av bränslen, bränsleblandningar och förorenade bränslen. Testresultat är mer än överraskande och intressant, då varje sensor erbjuder annat än väntad prestanda och användbarhet. Stämgaffel teknik till exempel har två sensorer representerade och den minst lovande sensorn visade sig vara lite mer exakt än den andra. NIR-sensor som utvärderas i detta arbete, har jämförbara resultat med stämgaffelgivare, när vi talar om väldefinierade bränsletdensitets mätningar. Trots detta, andra mätningar som är specifika för denna typ av NIR-teknik, erbjuder den inte resultat på den förväntade nivån.
In recent years global emissions standards have become more in more stringent when we refer to Heavy Duty (HD) Diesel engines. Moreover, every region or country has its own regulations with own levels of emissions for the main pollutants: CO, hydrocarbons (HC), NOx and particulate matter (PM). Also, the real life usage, always differ from the laboratory conditions in which the engines are tested in order to pass regulations. For a company like Scania, that is developing and using HD diesel engines and has an interest in selling its products world-wide, different emissions standards have a direct impact on the future of product development. Diesel engines equipping HD trucks or busses are continuously being improved in order to align to these standards, either by new and complex engine designs, combustion control strategies or exhaust after treatment systems (e.g. Catalyst, SCR, EGR, UDS, etc.). However, nothing can adapt a diesel engine for different fuel types that it can meet on a trip from Northern Sweden to southern part of Italy. That is why fuel quality and fuel properties are important aspects to account for when talking about engine development and emissions.This Thesis is proposing a series of answers regarding fuel quality measurements. First, definitions for some of the most important fuel properties are proposed. The impact on engine operation and emissions is also discussed. Secondly, a review of the current available on the market on board technologies is presented. These technologies are able to measure and detect these fuel properties. The onboard technologies are supposed to incorporate all laboratory measurement techniques capabilities used for analyzing fuel parameters, offer comparable results, a larger mobility and vehicle adaptability. At last, the thesis proposes three sensors that are incorporating two innovative measurement on board technologies, which are able to detect fuel properties. These sensors are tested with various type of fuels, fuel blends and contaminated fuels. Test results are more than surprising and interesting, with every sensor offering other than expected performance and applicability. Tuning fork technology for example has two representative sensors that are tested and the less expected sensor proves to be little more accurate than the other one. The NIR sensor that is evaluated in this work, has comparable results with tuning fork sensors, when we refer to well defined fuel density measurements. Nonetheless, other measurements specific to this type of NIR technology, do not offer at this level the expected results.

Abstract:

Bakgrund: AD/HD innebär en funktionsnedsättning med kärnsymptom som ouppmärksamhet, hyperaktivitet och impulsivitet. Personer med AD/HD har också ofta problem med känsloreglering. Intensiv dynamisk korttidsterapi (ISTDP) syftar till att hjälpa patienter till ökad förmåga att uppleva komplexa känslor genom att medvetandegöra dem. Terapiformens utgångspunkt är att många patienters problem skapas av känslomässigt undvikande och den betonar värdet av upplevelse av känslor i terapirummet. Studien syftade till att undersöka effekten av ISTDP på symtomen hos patienter med AD/HD som ett komplement till sedvanlig medicinbehandling. Frågan var om behandling riktad mot känsloreglering påverkar den globala symptombilden för personer med AD/HD. Metod: Studien är en naturalistisk pilotstudie med sex patienter som fick 10 sessioners behandling med ISTDP. Utfallsmåtten var Inventory of Interpersonal Problems, Adult ADHD Self Report Scale, Beck Anxiety Inventory och Patient Health Questionnaire-9. Primärt utfallsmått var Adult ADHD Self Report Scale. Patientens problem mättes vid 4 tillfällen, vid första, fjärde, sjunde och sista veckan av behandlingen. Resultat: Patienterna förbättrades signifikant på Inventory of Interpersonal Problems och Adult ADHD Self Report Scale och på Beck Anxiety Inventory. Det fanns dock en stor variation inom gruppen. Vissa patienter förbättrades tydligt, andra förblev oförändrade och någon försämrades. Slutsatser: ISTDP som ett komplement till sedvanlig medicinbehandling och kan hjälpa vissa personer med AD/HD att fungera bättre interpersonellt. Det fanns också tecken på minskning av symptomen på AD/HD samt visar tendenser till reducerad ångest. Ingen följsamhetskattning till ISTDP gjordes. Detta samt det låga deltagarantalet och avsaknaden av kontrollgrupp gör att det är svårt att generalisera resultaten. De ska snarare ses som indikationer på vikten av ytterligare forskning.

Abstract:

Enligt Socialstyrelsen (2004) förekommer diagnosen AD/HD hos 3-6 % av alla barn i grundskolan. Av dessa är 2/3 killar. Det finns olika teorier om vad som orsakar diagnosen, ärftlighet är en vanlig teori. Symtomen hos personer med diagnosen är väldigt olika. Överaktivitet är den vanligaste men även underaktivitet förekommer.

Litteraturens roll i läroplanerna har ändrats under åren. Fram till folkskolans inträde år 1842 var kyrkans inflytande total. Litteraturens betydelse har sedan varierat i läroplanerna, men i Lgr-80 får den en central roll. Enlig den senaste läroplanen, Lpo-94 menar man att läskunnighet är en förutsättning för att aktivt kunna delta i samhället.

Mitt mål med detta arbete är dels att sammanfatta vad AD/HD är och dels försöka ta reda på vilken uppfattning elever med diagnosen har kring diagnosen och litteratundervisningen i skolan. Därför har jag valt att utgå från ett elevperspektiv och jag har genomfört sex intervjuer med elever som har diagnosen AD/HD.

Av resultatet i min studie framgick det att eleverna anser att orsakerna till AD/HD kan vara flera, men ärftlighet betonas mest och fem av sex tillfrågade poängterar detta. Fem av sex angav även att de tyckte det var skönt att de fått diagnosen och att det hjälpt dem. De flesta eleverna tänker på böcker när de hör ordet litteratur men de nämner även tidningar, datorn, telefonen, spel och reklam. De uppger även att de har nytta av litteraturundervisningen. De blir glada av att läsa något de verkligen tycker om och de poängterar vikten av att litteraturen måste intressera dem. Eleverna nämner olika typer av stöd som de får i samband med litteraturundervisningen. Stöd som nämns är till exempel att det finns böcker av olika svårighetsgrad och olika tekniska hjälpmedel. De upplever dock att det finns för få böcker och att de ibland får för lite hjälp på lektionerna.

Abstract:

We present the first scattered-light images of two debris disks around the F8 star HD. 104860 and the F0V star HD. 192758, respectively similar to 45 and similar to 67. pc away. We detected these systems in the F110W and F160W filters through our reanalysis of archival Hubble Space Telescope (HST) NICMOS data with modern starlight-subtraction techniques. Our image of HD. 104860 confirms the morphology previously observed by Herschel in thermal emission with a well-defined ring at a radius of similar to 114. au inclined by similar to 58 degrees. Although the outer edge profile is consistent with dynamical evolution models, the sharp inner edge suggests sculpting by unseen perturbers. Our images of HD. 192758 reveal a disk at radius similar to 95. au inclined by similar to 59 degrees, never resolved so far. These disks have low scattering albedos of 10% and 13%, respectively, inconsistent with water ice grain compositions. They are reminiscent of several other disks with similar inclination and scattering albedos: Fomalhaut, HD. 92945, HD. 202628, and HD. 207129. They are also very distinct from brighter disks in the same inclination bin, which point to different compositions between these two populations. Varying scattering albedo values can be explained by different grain porosities, chemical compositions, or grain size distributions, which may indicate distinct formation mechanisms or dynamical processes at work in these systems. Finally, these faint disks with large infrared excesses may be representative of an underlying population of systems with low albedo values. Searches with more sensitive instruments on HST or on the James Webb Space Telescope and using state-of-the art starlight-subtraction methods may help discover more of such faint systems.

Cataloged from PDF version of thesis.
Includes bibliographical references (pages 69-73).
This thesis analyzes HD 82074, a solar-mass and low-metallicity subgiant star, using ground-based asteroseismology with the CHIRON spectrometer at the Cerro Tololo Inter-American Observatory (CTIO) and interferometry with the CHARA array on Mt. Wilson. The physical parameters of subgiant stars are of particular interest in the exoplanetary field due to their importance in understanding the relationships between planet occurrence rate and stellar properties such as age, metallicity and mass. Potential systematic uncertainties in the canonical stellar models make it especially important to independently determine the masses and radii of these stars. We determine HD 82074's radius using interferometry from CHARA, and we combine this result with measurements of the spacing and frequencies of the asteroseismic oscillations of HD 82074 to determine a stellar mass. We find that the star has a radius of 3.96 0.12 solar radii and a mass of 1.20 0.11 solar masses. While the radius is in excellent agreement with predictions from spectral analysis, the mass is 2.9-o- greater than the predicted mass. This suggests that errors of stellar models may be underestimated for low-metollicity or evolved stars. This study makes HD 82074 the third subgiant for which a physical radius is confirmed interferometrically and one of ten asteroseismically studied subgiants.

As video systems move from analog NTSC to HD digital video, it is also important to move with them accurate time stamping, real time text and graphics insertion capabilities. We will explore some of the tradeoffs and benefits between direct video insertion and data insertion into the SDI metadata. We will explore the impact transmission infrastructure has on time accuracy, positional control and data recovery when transporting HD-SDI video from source to destination. Further some the side effects of compression tools used (e.g. JPEG 2000, MPEG, H.264) to accomplish transport will be discussed.

Abstract:

This essay presents a case study regarding how some preschool teachers describe the diagnosis of AD/HD, and how they express their perception of children who show the symptoms associated with that diagnosis. We also wanted to study how the preschool teachers described their work with these children, and how the teachers responded to the children’s specific needs. The study draws on a qualitative study based on interviews with six preschool teachers in two municipalities in the Southern Stockholm region. All of the teachers had experience of children with an AD/HD diagnosis. Interviews were recorded and transcribed before analysis. The theoretical framework chosen for this essay is discourse analysis. We applied different parts of Fairclough’s and Foucault's methods of discourse analysis to clarify how language was used to describe children with AD/HD. The framework also allowed us to analyse how language may contribute to construct and maintain discourses about children with that diagnosis. We could discern from the interviews with the preschool teachers that children with AD/HD were mainly described as problematic. Another conclusion is that although the teachers showed an awareness of gender issues when speaking of children generally, their choice of words when talking about children with AD/HD implied old stereotypical gender-based expectations. Finally, the preschool teachers described both advantages and disadvantages of diagnosing children, however, most of them emphasised a need for a diagnostic categorization to facilitate their work with these children.

Abstract:

Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed. The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system. Conventional strategies used to raise the exhaust temperature were also tested and compared to the valve strategies developed in this project. The results show that all strategies tested increased the exhaust temperature at low loads, but by different magnitude, different emissions, and fuel consumption. The exhaust brake showed highest potential for heating the exhaust after-treatment system quickly, and opening of the exhaust valve during the intake stroke in combination with intake throttle was most efficient for maintaining the temperature with low fuel consumption. It also proved that this lift height can be kept constant at different loads by the use of throttle, exhaust brake, or Miller late intake valve closing. The strategies of Miller, valve lift during the intake or exhaust strokes, and valve phase shift also proved to reduce NOx emissions at loads up to 50% . It can be concluded that variable valve actuation can be used to increase exhaust temperature at low load, and that there is also a great potential of reducing emissions at the same time.
Med hårdare lagkrav på emissioner från tunga Dieselmotorer behövs ofta efterbehandlingssystem för att katalytiskt omvandla NOx,CO och HC -emissioner. Dessa katalytiska system är temperaturberoende, och tillräcklig temperatur uppnås ofta inte i avgaserna från en modern Dieselmotor under låglast. På grund av detta krävs åtgärder för att höja avgastemperaturen samtidigt som låga avgasemissioner och låg bränsleförbrukning bibehålls. Detta projekt har varit fokuserat på att utveckla strategier för avgas- och insugsventil-lyftprofiler med målet att höja avgastemperatur i kombination med låga emissioner och låg bränsleförbrukning. Strategierna har testats på en encylindermotor utrustad med hydrauliska variabla ventiler. Konventionella strategier som används för att höja avgastemperaturen har också testats och jämförts med de ventilstrategier som har utvecklats i detta projekt. Alla strategier som testades i detta projekt höjde avgastemperaturen, men olika mycket och med olika avgasemissioner och bränsleförbrukning. Avgasbroms visade störst potential för att snabbt värma upp ett efterbehandlingssystem, och lyft av avgasventilerna under insugstakten i kombination med inloppstrottel visade störst potential för att bibehålla avgastemperaturen i relation till låg bränsleförbrukning. Det visade sig även att denna lyfthöjd kan hållas konstant vid olika last genom att kompensera med trottel, avgasbroms eller Miller sen stängning. Emissioner i form av NOx kunde sänkas genom Miller, ventilöppning under insug eller avgastakt, eller fasförskjutning av ventiler på laster upp till 50%. Slutsatsen som kan dras är att de variabla ventilstrategier som testats i detta projekt kan användas för att höja avgastemperaturen vid låglast, och att det finns stor potential att samtidigt minska avgasemissioner.

Abstract:

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIRO
A indústria de cinema e TV tem usado amplamente a técnica de Chroma Key, também conhecida por Blue Screen Matting. Esta técnica revolucionou, ao longo do tempo, a indústria do entretenimento, permitindo que cenas impossíveis de serem criadas se tornassem realidade. A evolução dessa técnica permitiu que produções complexas passassem a ter melhor controle e custos mais baixos. Porém, essa técnica conta com uma série de etapas de preparação, que demandam recursos financeiros elevados e planejamento preciso. Ademais, erros de continuidade costumam criar sérios problemas na pós-produção. Atualmente, a indústria de entretenimento está procurando outras técnicas de matting que funcionem com fundos variados. O uso destas técnicas ainda está restrita a trabalhos acadêmicos e a softwares de manipulação de imagens estáticas. O presente trabalho tem como objetivos fazer uma análise dos processos atuais de chroma key e partir para a proposta de uma técnica de matting com fundos variados em imagens de alta definição (HD – High Definition). Dois métodos para o cálculo de valores de alpha são apresentados: um método global baseado em clusters e um método local baseado em potencial elétrico.
The film and broadcast industry have been massively using the Chroma Key technique, also known as Blue Screen Matting. This technique deeply transformed the entertainment industry, allowing impossible scenes become reality. The evolution of this technique allowed that complex productions could have better control and lower costs. However, this technique needs a sequence of preparation stages, which require high budgets and precise planning. Furthermore, continuity errors usually cause serious post-production problems. Currently, the entertainment industry is searching for other matting techniques that work on any kind of background. The use of these techniques is still restricted to academic works and softwares of still image manipulation. The present work has the goal of making an analysis of the current chroma key processes and aims to propose a matting technique over any type of background in High Definition images. Two methods of calculating alpha values are presented: a local method based on clusters and a local one based on electric potential.

Abstract:

Bjälklag av förspända håldäckselement (HD/F) är en kostnadseffektiv lösning för byggnader med stora spännvidder där öppen planlösning eftersträvas. Den ursprungliga konstruktionen för byggnader bestod av HD/F-element och väggar som upplag. Senare blev användning av balkar som upplag allt vanligare lösning. Balkar kallas i det fallet för flexibla upplag. Den här konstruktionslösningen i sig medför sämre bärförmåga hos HD/F-element eftersom balken deformeras vid belastning, och på grund av samverkan mellan balk och HD/F-element uppstår tillkommande spänningar i håldäckselement. Det här arbetet hade som syfte att undersöka på vilka sätt försämrad bärförmåga hos HD/F-element tas hänsyn till och hur det kan tillämpas vid dimensionering. Detta resulterade i ett beräkningexempel enligt en av de olika beräkningsmodeller som finns. I beräkningasexemplet behandlas bjälklag i ett parkeringshus, och resultatet visar att bjälklaget håller för belastningen med hänsyn till flexibla upplag.
Floor structures constructed by using prestressed precast hollow-core slabs is costeffective solution for buildings that require long span floors. Nowadays the most common design for this type of floors consists of HC slabs supported on beams. In this case beams are called flexible supports because of deflection in the beams. These deflections cause addition stresses in the HC slabs that has to be taken into accout. The purpose of this study was to find out which calculation models exist and how they can be used in design process. As s result of project a calculation example is presented in this report which describes one of possible calculation models.

Abstract:

An increasing number of observations have shown that gaseous debris discs are not an exception. However, until now, we only knew of cases around A stars. Here we present the first detection of (CO)-C-12 (2-1) disc emission around an F star, HD 181327, obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) observations at 1.3 mm. The continuum and CO emission are resolved into an axisymmetric disc with ring-like morphology. Using a Markov chain Monte Carlo method coupled with radiative transfer calculations, we study the dust and CO mass distribution. We find the dust is distributed in a ring with a radius of 86.0 +/- 0.4 au and a radial width of 23.2 +/- 1.0 au. At this frequency, the ring radius is smaller than in the optical, revealing grain size segregation expected due to radiation pressure. We also report on the detection of low-level continuum emission beyond the main ring out to similar to 200 au. We model the CO emission in the non-local thermodynamic equilibrium regime and we find that the CO is co-located with the dust, with a total CO gas mass ranging between 1.2 x 10(-6) M-aS center dot and 2.9 x 10(-6) M-aS center dot, depending on the gas kinetic temperature and collisional partners densities. The CO densities and location suggest a secondary origin, i.e. released from icy planetesimals in the ring. We derive a CO+CO2 cometary composition that is consistent with Solar system comets. Due to the low gas densities, it is unlikely that the gas is shaping the dust distribution.

Abstract:

In order to perform the production testing of the video quality of manufactured set-top-boxes for digital television, an FPGA-based measurement system is designed. Background on sampling and video signals are given, as well as the requirements given by Motorola. From this, a design is proposed and implemented. The demonstrator works as planned and shows good performance in regards to signal to noise ratio and differential gain. The implemented digital communication protocols, such as USB and I2C, also work as expected.

The main conclusion from this thesis is that implementing video test systems using FPGA is a good approach offering many advantages compared to commercial video measurement instruments or plug-in cards for PCs.

Abstract:

Överums bruk AB är idag en ledande tillverkare av jordbruks maskiner där främst Europa är största marknaden. Deras främsta produkt är vändskiveplogen som är världsledande just nu på marknaden med lågt dragkrafts behov och hög effektivitet. Då konkurrensen ökar och kostnaderna inte minskar så krävs anpassning av nya konstruktioner till produktionen för att få ner kostnaderna men även minska antalet olika detaljer. I det här projektet utgår jag utifrån ett förslag på en ny huvudkomponent kallad topp till Cx-plogen. Den ska ersätta den gamla toppen men även den spanska toppen som används på den spanska marknaden. HD-toppen sitter längst fram på vändskiveplogen och dess funktion är att lyfta, dra och hålla upp plog ramen. Först gjordes en grundlig genomgång av processen så att problem och förbättringsmöjligheter upptäcks. Sedan gjordes olika beräkningar för att på så sätt få fram hur mycket man tjänade på de förändringar som gjordes. Slutsatsen är att kostnaderna är väldigt beroende av bearbetningstiden men också på vilken kapacitet som finns. Med kapacitet menar då produktions förmåga till anpassning till att göra olika moment för många produkter effektivt. En av slutsatserna av det här arbetet är att det ofta är svårt att konkurrera med företag som tillverkar special detaljer till olika industrier. Alltså det som kallas legotillverkning. Det är då i många fall bäst att skicka över en del moment i produktionen av detaljer till legotillverkare som gör det mer effektivt med andra maskiner för att det företaget kan vara expert på en viss tillverkningsprocess. På så sätt kan man reducera totala kostnaden på produkten. Ytterligare slutsatser av det här arbetet, är att kvalitets problem kan betyda stora kostnader om man inte åtgärdar det. Inga stora kostnader upptäcktes i arbetet men på lång sikt kan det bli ekonomiskt oförsvarbart. Då menas att kostnaderna kan öka okontrollerat till en nivå som direkt påverkar totala ekonomin för Överums bruk
Överums Bruk AB is a leading manufacturer of agricultural machinery where primarily Europe's largest market. Their main product is the mouldboardplough, the world leader right now in the market with low draft requirement needs and high efficiency. As competition increases and the costs are not reduce the required adaptation of new designs to production in order to bring down costs but also reduce the number of different parts.In this project, I start by on a proposal for a new main component called top to the Cx-plough. It will replace the old top but also the Spanish top used in the Spanisk market. The top is seated at the fron of the mouldboardplough and its purpose is to lift, pull and hold up the plough frame. First, a thorough review of the process so that problems and improvement opportunities could be identified.I worked on with various calculations in order to conceive how much you could earn on the changes made. The conclusions is that the costs are very dependent on the processing time but also on the capacity available. With the capacity I mean the production capacity to adapt to make various parts for many products more effectively.One of my conclusions from special work is that it is often difficult to compete with companies that makes special parts for various industries. So what are known as contract manufacturing. It is the best in many cases to send over some elements of the production of details to contract manufacturer that makes them more effectively with other machines for the company to be experts on a certain manufacturing process. That way you can reduce the overall cost of the product.Additional findings of this study is that quality problems can mean significant costs if you do not fix it. No sized costs were discovered in the work but in the long run it may be economically indefensible. This meant that cost could increase uncontrollably to a level that directly affects the overall economics of Överums bruk.

In our first installment, analog and HD video terms were compared. It was shown that resolution is three-dimensional in HD. High HD data rates force the use of video compression in order to transport video. Compression compromises video detail and introduces latency. Latency affects the overlay of time critical measurements. It is therefore important to time stamp at the source. In this volume, the focus is on the key regions of the HD video frame and metadata. SMPTE specifications are the foundation on which MISB builds its use of metadata. It will be shown that only two KLV packets can hold all TSPI and calibration data with frame-by-frame updates. This capacity is new in HD. Metadata is permanently merged with images and the time that both were collected. We show how employing the KLV metadata packet can result in a single video record where picture taking are all in lockstep. Using KLV metadata enables one to record clean video while retaining the ability to place crosshairs and data during playback.

Abstract:

We report on low resolution (R~3000) spectropolarimetry of the A0 supergiant star HD 92207. This star is well-known for significant spectral variability. The source was observed on seven different nights spanning approximately 3 months in time. With a rotation period of approximately 1 year, our data covers approximately a quarter of the star's rotational phase. Variability in the continuum polarization level is observed over this period of time. The polarization across the Halpha line on any given night is typically different from the degree and position angle of the polarization in the continuum. Interestingly, Hbeta is not in emission and does not show polarimetric variability. We associate the changes at Halpha as arising in the wind, which is in accord with the observed changes in the profile shape and equivalent width of Halpha along with the polarimetric variability. For the continuum polarization, we explore a spiral shaped wind density enhancement in the equatorial plane of the star, in keeping with the suggestion of Kaufer etal (1997). Variable polarization signatures across Halpha are too complex to be explained by this simple model and will require a more intensive polarimetric follow-up study to interpret properly.

Abstract:

Context. Understanding the diversity of planets requires studying the morphology and physical conditions in the protoplanetary disks in which they form. Aims. We aim to study the structure of the similar to 10 Myr old protoplanetary disk HD 100453, to detect features that can trace disk evolution and to understand the mechanisms that drive these features. Methods. We observed HD100453 in polarized scattered light with VLT/SPHERE at optical (0.6 mu m, 0.8 mu m) and near-infrared (1.2 mu m) wavelengths, reaching an angular resolution of similar to 0.02 '', and an inner working angle of similar to 0.09 ''. Results. We spatially resolve the disk around HD 100453, and detect polarized scattered light up to similar to 0.42 '' (similar to 48 au). We detect a cavity, a rim with azimuthal brightness variations at an inclination of similar to 38 degrees with respect to our line of sight, two shadows and two symmetric spiral arms. The spiral arms originate near the location of the shadows, close to the semi major axis. We detect a faint feature in the SW that can be interpreted as the scattering surface of the bottom side of the disk, if the disk is tidally truncated by the M-dwarf companion currently seen at a projected distance of similar to 119 au. We construct a radiative transfer model that accounts for the main characteristics of the features with an inner and outer disk misaligned by similar to 72 degrees. The azimuthal brightness variations along the rim are well reproduced with the scattering phase function of the model. While spirals can be triggered by the tidal interaction with the companion, the close proximity of the spirals to the shadows suggests that the shadows could also play a role. The change in stellar illumination along the rim induces an azimuthal variation of the scale height that can contribute to the brightness variations. Conclusions. Dark regions in polarized images of transition disks are now detected in a handful of disks and often interpreted as shadows due to a misaligned inner disk. However, the origin of such a misalignment in HD100453, and of the spirals, is still unclear, and might be due to a yet-undetected massive companion inside the cavity, and on an inclined orbit. Observations over a few years will allow us to measure the spiral pattern speed, and determine if the shadows are fixed or moving, which may constrain their origin.

Abstract:

Inledning: Diagnostisering och behandling av AD/HD sker primärt i enlighet med forskning som beskriver tillståndet som ett neuropsykiatriskt funktionshinder, vilket implicerar biologiska orsaker. Något som fortfarande är underrepresenterat inom forskningen är relationen mellan diagnosen AD/HD och anknytnings- och uppväxtförhållanden. Syftet med denna uppsats är att undersöka fördelningen mellan olika anknytningsmönster hos föräldrar i familjer där barn fått diagnosen AD/HD. Frågeställningar: Hur ser fördelningen av anknytningsmönster ut hos föräldrar vars barn har fått diagnosen AD/HD? Hur ser samstämmigheten ut mellan parens anknytningsmönster? Metod: En kvantitativ metod med explorativ ansats har använts för studien. Självskattningsformuläret ASQ har använts för att skapa anknytningsprofiler utifrån en given analysmodell. Informationen har bearbetats och analyserats på tre nivåer för att hitta mönster i deltagarnas och gruppens anknytningsmönster. Resultatet har presenterats med deskriptiv statistik. Resultat: 97 % av de deltagande föräldrarna uppvisade otrygga anknytningsprofiler. Fördelningen mellan otrygg och trygg anknytning var jämn mellan kön, åldergrupper och utbildningsnivåer. Avseende anknytningsprofiler var det en tydlig övervikt av Undvikande (47 %) och Ambivalent (40 %) anknytningsprofil relativt Ängslan (10 %) och Trygghet (3 %). Diskussion: Denna studie, ihop med andra studier har visat att det finns en hög grad av otrygga anknytningsmönster i familjer med AD/HD diagnoser. Och trots att studiens resultat inte kan säga något om huruvida otrygga anknytningsmönster orsakar AD/HD symptom, eller AD/HD orsakar otrygga anknytningsmönster, går ändå studiens resultat i linje med att familjeterapeutiska interventioner kan vara klokt att sättas in. I en familjeterapeutisk situation kan stora förändringsarbeten göras i familjesystemet, oavsett skäl till problematiken, vare sig de är biologiskt eller relationellt orsakade.
Introduction: Diagnosis and treatment of AD/HD is primarily done in accordance with research describing the state as a neurodevelopmental disorder, which implies biological causes. Still less common within research is the relation between AD/HD and attachment and childhood conditions. The purpose of this thesis is to investigate the distribution of attachment patterns among parents in families where children has been diagnosed with AD/HD Question formulation: What does the distribution of attachment patterns look like amongst parents whose children have been diagnosed with AD/HD? What are the combinations of attachment patterns amongst the couples? Method: A quantitative method with an explorative approach has been used for this study. The ASQ self-evaluation questionnaire has been used to generate the attachment profiles from the given analysis model. Information has been processed and analyzed on three levels to find patterns within the attachment patterns of the individuals and the group. The result is presented as descriptive statistics. Result: 97 % of the participating parents displayed unsecure attachment profiles. The distribution between secure and insecure attachments was equal between sexes, age groups and education levels. Amongst attachment profiles there was an overweight towards Avoidance (47 %) and Ambivalence (40 %) in comparison to profiles Anxiety (10 %) and Security (3 %). Discussion: This study, together with other studies, has shown a high degree of insecure attachment patterns in families with AD/HD diagnosis. And although the study result can’t say anything about insecure attachments causing AD/HD symptoms, or AD/HD causing insecure attachment patterns, the study is in line with the fact that family-therapeutic interventions can be wise to use. In a family-therapeutic situation real change work can be done in the family system, regardless if the causes are biologically or relationally induced.

Abstract:

Huntington's disease (HD) is an inherited disease that causes degeneration of adult neurons in the striatum and later in the cortex. Although most studies have focused on adulthood, some evidence suggests that this disease might have a neurodevelopmental component. To try to address this question, we generated a protocol to derive 3D ventral organoids from isogenic control and pathologic hES cell line to mimic in-vitro the development of the ventral telencephalon. Immunocytochemistry analyses show correct identity acquisition, particularly if compared with dorsal protocols. These data are supported by single cell RNA-seq analyses that highlight the presence of ventral progenitors and GABAergic neurons with no dorsal subpopulations. Compared to controls, HD organoids show a 50% reduction in the number of regions that resemble the ventricular zone of the developing brain together with abnormalities in their polarity and compromised radial distribution of GSX2+ and MASH1+ progenitors. These early defects are combined with aberrant cell cycle regulation as shown by a 45% reduction in the number of KI67+ cells, a 95% increase in asymmetric horizontal divisions and a 15% increase in cell cycle exit ratio. Moreover, scanning electron microscopy (SEM) analyses reveal irregular neuronal architecture in HD organoids. Together our data suggest that the presence of mutant Huntingtin (mHTT) causes a developmental defect in the cellular organization of ventral organoids. This 3D model has therefore paved the way to a better understanding of the potential neurodevelopment aspects of this disease and may provide a platform to further screen and comprehend this complex disease. In line, we are now analyzing single cell data from HD organoids to unveil the transcriptional pathways affected by mHTT and in parallel we are setting up a co-culture system of control and HD cells to study cellular interactions between the two lines and to discriminate cell-autonomous versus non-autonomous defects.

Bakgrunden till arbetet bygger på våra tidigare erfarenheter från den verksamhetsförlagda utbildningen där vi upplever svårigheter med att undervisa elever utifrån deras behov och förutsättningar. Syftet med arbetet är att undersöka vilka erfarenheter lärare har av att undervisa elever med diagnosen AD/HD. Vi har även tagit del av idrottslärares strategier i förhållande till dessa elever. För att uppnå vårt syfte har vi valt att genomföra en kvalitativ undersökning som är baserad på semistrukturerade intervjuer av lärare i ämnet Idrott och hälsa. Resultatet visar att lärarna använder olika strategier för elever med AD/HD. Vidare upplever lärarna att det krävs mer utbildning om diagnosen på universiteten.

Abstract:

The active F dwarf HR 1817 represents the upper temperature extreme of what are broadly termed solar-type stars - stars which have the same internal structure as the Sun, albeit in this case with a much smaller convective zone. To date, studies of the active surface features and magnetic fields of solar-type stars have been restricted to G and K dwarfs. This thesis investigates the surface and magnetic features of HR 1817 using the techniques of Doppler and Zeeman Doppler Imaging, resulting in tomographic maps of the stellar surface and magnetic field. Cooler stars than HR 1817 exhibit large polar spots, and while HR 1817 also exhibits a polar spot, it is not nearly as large as those usually seen. The lower-latitude surface features of HR 1817 are weak but well defined and cover a relatively small area of the stellar surface. Total spot coverage is relatively small (~ 1.7 - 2 per cent). Zeeman Doppler Imaging reveals that HR 1817 exhibits a richly-detailed, though weak magnetic topography. A ring of azimuthal field appears around the pole, while the radial field exhibits many well-defined and distinct bipolar mid-latitude magnetic features, perhaps indicating a more dominant interface dynamo as opposed to the posited distributed dynamo of cooler active dwarfs. Finally, a differential rotation measurement of the star indicates an extremely large rotational shear. Values for the equatorial rotation and rotational shear of 6.494 +/- 0.010 rad/d and 0.256 +/- 0.017 rad/d respectively are found. This equatorial rotation is equivalent to a rotational period for HR 1817 of ~ 0.98 days. The very high rotational shear of 0.256 rad/d is fast enough for the equator to lap the pole in approximately 23 days.

A detecção e o subsequente rastreamento de objetos em sequencias de vídeo é um desafio no que tange o processamento de vídeos em tempo real. Nesta tese propomos um método de detecção em tempo real adequado para o processamento de vídeos de alta definição. Neste método utilizamos um procedimento de segmentação de quadros usando as imagens integrais de frente, o que permite o rápido descarte de várias partes da imagem a cada quadro, desta maneira atingindo uma alta taxa de quadros processados por segundo. Estendemos ainda o algoritmo proposto para que seja possível detectar múltiplos objetos em paralelo. Além disto, através da utilização de uma GPU e técnicas que podem ter seu desempenho aumentado por meio de paralelismo, como o operador prefix sum, conseguimos atingir um desempenho ainda melhor do algoritmo, tanto para a detecção do objeto, como na etapa de treinamento de novas classes de objetos.
The detection and subsequent tracking of objects in video sequences is a challenge in terms of video processing in real time. In this thesis we propose an detection method suitable for processing high-definition video in real-time. In this method we use a segmentation procedure through integral image of the foreground, which allows a very quick disposal of various parts of the image in each frame, thus achieving a high rate of processed frames per second. Further we extend the proposed method to be able to detect multiple objects in parallel. Furthermore, by using a GPU and techniques that can have its performance enhanced through parallelism, as the operator prefix sum, we can achieve an even better performance of the algorithm, both for the detection of the object, as in the training stage of new classes of objects.

Abstract:

Håldäck är en vanligt förekommande betongprodukt som ger lägre materialkostnadader och används bland annat där man önskar längre spännvidder för en öppnare planlösning. Strängbetong konstruerar, tillverkar och monterar prefabricerade betongelement där håldäck är en av de produkterna. För att få en stabil och robust konstruktion behöver betongelementen kopplas samman. Detta för att undvika fortskridande ras av en byggnad ifall en olycka skulle inträffa som t.ex. påkörning eller explosion. Examensarbetet syftar till att undersöka två så kallade raskopplingar mellan ett håldäck och en betongvägg. Ena kopplingen är enligt Strängbetongs standard och utformas med en bygel igjuten i håldäckets kanal, denna standardlösning ger dock extra arbete vid tillverkningen. Därför undersöks ifall det är praktiskt möjligt att montera bygeln i fogen mellan två håldäck istället. Försöken är till för att undersöka ifall armeringsbygeln blir tillräckligt omsluten av betong och att fogen därmed inte spricker sönder vid belastning av järnet. Resultaten från den praktiska delen samt från den teoretiska beräkningen sammanställs sedan för att kunna se om praktiken skiljer sig från teorin. Domkraftens dragkapacitet var 20 ton som gjorde att försöken begränsades till att enbart kunna konstatera att utdragningskapaciteten i en håldäcksfog och kanal är minst 195 kN. Resultatet från dragförsöken av armeringsbyglarna igjutna i håldäckets fog och kanal blev materialbrott i armeringen. Resultaten visar att det är möjligt att ersätta dagens standard koppling i kanalen med att istället montera bygeln i fogen mellan två håldäck. Examensarbetet kan ses som ett försök till att testa ifall kopplingen var möjlig och kan vara till grund för vidare studering.
Hollow core slabs are a common concrete product that reduces material costs and is used, among other things, where you want longer ranges for a more open plan solution. Strängbetong designs, manufactures and assembles prefabricated concrete elements where hollow core slabs are one of the products. To get a stable and robust construction, the concrete elements need to be connected. This in order to avoid progressive collapse of a building in case of an accident, such as an collision or explosion. This dissertation aiming to investigate two so-called collapse-couplings between a hollow core slab and a concrete wall. One of the connections is according to Strängbetong's standard and is designed with a S-reinforcing bar in the hollow core slab void, but this standard solution provides extra work in the manufacture. That's why it's an advantage, if it is practically possible, to assemble the bar in the joint between two slabs instead. The tests are in order to investigate whether the bended reinforcement bar becomes enought enclosed by concrete and that the concrete in the joint does not crack apart. The results from the practical part and from the theoretical calculation are then compiled to see if the reality differs from the theory. The capacity of the jack was 20 ton, which made the tests limited to only note that the pull-out capacity of a hollow core slab joint and void is at least 195 kN. The result of the tests gave material ultimate in the reinforcement. The results show that it is possible to replace today's standard connection in the void by instead assembly the bar in the joint between two slabs. The dissertation can be seen as an attempt to test if the connection is a possible solotion and the work may be the basis for further study.

Abstract:

The company LightLift Esystems AB manufactures patented motorized lift systems for the illumination of halls with high ceilings. The company wants a new design for singular heavy lights in order to be more competitive. This project consists of the development of the new design under the requirements and specifications imposed by the company. The new design must support lights up to 300kg and keep the overall dimensions as low as possible without modifying the driving unit. This document contains all the designing steps followed to reach the final solution as well as the material selection, manufacturing process and assembly of all the parts that form it. The solution obtained shows to be very competitive with other alternative products, since this new design triples their maximum load capacity while the dimensions are very similar. In this context, the optical appearance was also very important to the company and so it was another main objective of this project. From an aesthetical point of view, the final solution proves to be very compact and versatile since it can either be hidden behind a false ceiling or covered by a plastic case that gives the design a very nice look. Finally, the solution achieved fulfils all the requirements and specification previously imposed. It is reliable, compact, cheap to manufacture, easy to assembly and it has a good optical appearance.
LightLift Esystems AB tillverkar patenterade, motoriserade lyftsystem för belysningsarmaturer till utrymmen med höga takhöjder. Företaget vill utveckla en ny konstruktion för enstaka punktbelysningar för att utöka sin konkurrensförmåga. Föreliggande projekt innefattar utveckling av en ny konstruktion utgående från en av företaget given specifikation. Den nya konstruktionen skall kunna hantera laster upp till 300 kg och dimensionerna skall hållas så små som möjligt med bibehållande av den ursprungliga lyftenheten. Detta dokument innehåller alla utvecklingssteg som följts fram till slutlig lösning, likaså materialval, val av tillverkningsmetod och monteringssätt för samtliga komponenter. Den valda lösningen visar sig vara konkurrenskraftig i jämförelse med alternativen emedan den kan lyfta tredubbla lasten med bevarade yttre dimensioner. Av konkurrensskäl är självklart också formgivningen av betydelse för uppdragsgivaren, varför även hänsyn till detta togs. Från estetisk synpunkt visar sig den valda lösningen vara fördelaktig emedan den lika lätt kan döljas bakom ett "falskt" innertak som kapslas in i en lämpligt utformad kåpa av plast. Lösningen uppfyller således alla de ställda kraven i specifikationen. Den är tillförlitlig, kompakt, billig att tillverka, lätt att montera och har en tilltalande formgivning.
