Abstract:

The main objective of this thesis is to introduce the reader to the problematics of air-launch and to a custom design solution applying this concept. The specifics of this method of bringing a payload into orbit are described and explained. Overview of projects which use aircraft to launch spacecraft is included. Determination of primary parameters of a launch vehicle designed to carry a payload of a specified mass is conducted. The required flight performance has been estimated, a computational model has been developed in software MATLAB, and a multidisciplinary optimization of the design parameters has been performed using a genetic algorithm optimization method. Parameters of the designed air-launched rocket are compared with those of a ground-launched rocket. According to the specific criteria, the Airbus A310-300 aircraft was selected as the most suitable transport aircraft to be used for launching the designed launch vehicle. The last part of the thesis is devoted to the proposal of necessary modifications and estimation of the flight performance.

Abstract:

Denna studie handlar om hur förskollärare kan iscensätta en matematikundervisning med hjälp av digitala verktyg på ett enkelt och roligt sätt. Läroplanen för förskolan Lpfö 18 anger att barnen ska få möjlighet att utveckla digital kompetens samt att utbildningen ska vara rolig och lärorik (Skolverket, 2018). Vi vill med denna studie bidra med kunskap om hur ett tvärvetenskapligt arbetssätt kan genomföras med hjälp av Bishops matematiska aktivitet design samt genom urskiljning och variation. Metoden som vi har använt i denna studie är att vi har genomfört en digitaliserad matematikundervisning med hjälp av variationsteorin och med inspiration från learning study. Undervisningen var inspirerad av barnprogrammet Supersagan där barnen genom den matematiska aktiviteten designa fick erfara de geometriska formerna samt att vi fick möjlighet till att berika vår profession. Resultatet visar att en undervisning med fokus på design kan bidra till ett matematiskt lärande för barn när förskolläraren riktar barnens uppmärksamhet mot lärandeobjektet och dess kritiska aspekter, visar på likheter och skillnader samt ger barnen tillgång till de rätta matematiska begreppen. Resultatet visar även att barns uttryck för matematik synliggörs genom deras förklaringar både verbalt och icke verbalt, deras tidigare erfarenheter samt att matematik uttrycks spontant i lek.

Abstract:

The purpose of this thesis is to describe and analyse the visual expressions of Street Art that occurs in the public space, and by doing so, to study this specifi c practice, and also elucidate the relation between public space as a democratic idea, a place for freedom of speech and as a planned, aesthetically shaped place. The intention is to throw light upon a central part of many young peoples lives in a didactic aspect. In this thesis I discuss Street Art as an informal image making in public space that young people use as tools to make meaning, but also as a form of resistance. The methodologies used in the study are ethnography and visual ethnography, where observational studies of Street Art as practice, interviews and interpretation of photographs (my own, and my informants) are performed and analysed. Theoretically, the study has a didactic and semiotic approach but I also rely on Cultural Studies as a research fi eld in order to be able to pick up different kinds of theories. From three platforms; public space and public place and places for Street Art, aesthetic learning processes within this specifi c practice, and fi nally the expanded fi eld of Art and the similarities and differences between formal Art and Street Art I have outlined four themes; ephemerality, the criteria for Street Art practice, how the work is being done, as a collective and individual practice, the struggle of space in public space, and fi nally high and low in Art and culture. By describing and analysing this informal image making light is thrown upon the aesthetic learning process that occurs, the didactic aspect of this practice and the communication that the images articulate. As a result, the study shows that Street Art, in spite of its illegal mark, points out that it is an aesthetic production and a creative practice that consists of resistance, meaning making, achieving knowledge through practice, and above all a way to use the city, to become a part of the city. The thesis contributes with the suggestion that this informal aesthetic learning process is a way to form identity, make meaning, take part of public space, and through symbolic resistance demand ones rights of expression.

Författare: Terese Gustafsson och Fanny Janson Handledare: Kjell Arvidsson  Examinator: Mikael Lundgren Titel: “Det handlar inte om att skicka iväg raketer, utan det handlar om att sätta hela skogen i brand”. En studie om organisering och klusterbildning inom svensk musikbransch. Syfte: Syftet med denna uppsats är att genom undersökning och analys av hur den organisatoriska uppbyggnaden av svensk musikbransch ser ut komma fram till vilka faktorer som kan ligga bakom en branschs framgångar. Metod: En kvalitativ forskningsmetod har använts i fallstudien och primärdata har samlats in genom genomförande av åtta semistrukturerade intervjuer. Slutsats: Vi fann att organiseringen och det kluster som en bransch verkar i har stor betydelse för dess framgång. Socialt kapital utgör stor vikt i ett kluster och att komma in på den sociala arenan är därför av vikt, men det kräver att redan etablerade aktörer är villiga att släppa in nya aktörer på den sociala arenan. Samarbeten som överskrider branschgränser har blivit viktigare i takt med att globaliseringen satt ökad press på innovation och kreativa lösningar på problem. Att verka i kluster ger organisatoriska fördelar som nära samarbeten, kunskapsutbyte och ökad kreativitet, men kan skapa nackdelar som homogenitet och inskränkthet. Bättre resultat uppnås när aktörer samverkar och idéen om "Do It Yourself" stämmer inte.
Abstract The Purpose of this paper is to, through analysis of how the organizational structure of the Swedish music industry looks, come to a conclusion of what factors might be behind an industry's success. The case study have been done by using a qualitative research method and the primary data is collected by semi-structured qualitative interviews We came to the conclusion that how an organization and the cluster an industry operates within, is of great importance for its success. Social capital is important in a cluster. It is therefore of great importance to be part of the social scene, but it requires that actors within the social scene accept new actors to enter. Collaborations that exceed industry boundaries have become of more importance as globalization have put increasing pressure on innovation and creative solutions to solve problems. To operate within clusters provide organizational benefits like collaborations, knowledge spillover and increased creativity. But it can also give negative effects such as homogeneity and parochialism. Better results are achieved when stakeholders work together and the idea of "Do It Yourself" is not true.

Abstract:

The purpose of this study is to emphasize the democratic term. We wanted to study how pedagogues act and deal with their own feelings, when they meet the thoughts and feelings of the children around the topic gathering in preschool. Our starting point was the answers from the interviews we held. Our questions were "What do the children and pedagogues think is the purpose of the gathering? How do the children and pedagogues experience that influence and participation are given to the children on the gathering? How do the children and pedagogues see to children`s participation on the gathering? Do the pedagogues experience the gathering from the children´s perspective?" We interpret the answers with Husserls phenomenologic theory to get closer to the subjective feeling. In our studie we have discovered that children´s and pedagouges view on influence and participation do differ. We also included children´s perspectiv to the studie. The pedagouges view on children´s perspective involves the preconception of how the preschool´s activity´s should be done. Our conclusion reads: The children do not only need to be heard. They need to be listened upon to be able to create a feeling of the democracy´s parts, where influence and participation are important aspects in our society. Where everyone´s value should be equally considered, regardless of age or any other entities of the power factors.

Abstract:

Denna rapport behandlar en radarsensors förmåga att upptäcka 107 mm raketerberoende på hur sensorn positioneras i förhållande till skyddsobjektet.Fältförsök, underrättelser och stridserfarenheter har visat att dessa raketer ärvanligt förekommande samt svåra att detektera med radarsensorer. En modell för hur räckviddsökning beror på olika sensorpositioner har skapats genom att använda dokument från USA och forna Sovjetunionen beskrivande ballistik tillsammans med teorier för hur räckvidd påverkas av radarmålarea (RCS) samten beskrivning av RCS tillhandahållen av FOI. Resultat från körningar iMATLAB visar att sensorpositioner inom 300 meter från skyddsobjektet ärfördelaktiga vid en skottvidd av 3000 meter. Som tumregel för att uppnå maximal sensorprestanda bör strävan vara att placera sensorn på ett avståndfrån skyddsobjektet understigande 10% av förväntad skottvidd.

Abstract:

Computational Fluid Dynamics (CFD) simulations are presented within this study for super-cooled liquid oxygen atomisation and gasification in a subcritical chamber operating at 1MPa. Relatively low cost simulation techniques have been used and their accuracy evaluated. Gasification efficiency expected from theory is compared with simulation results and physical limitation in addition to modelling limitations are discussed. Impinging jets have been used within the simulations with the intent of atomising the incoming liquid oxygen, followed by injection of hot water vapour perpendicularly, to increase turbulent mixing, residence time and in turn expected gasification efficiency. A computational fluid dynamics heating analysis is also included in order to highlight constraints on the chamber geometry imposed by transient rapid oxidation material limits. 316 stainless steel and 3D printed Inconel 718 were investigated experimentally to identify their transient macroscopic rapid oxidation limits. This information supplements existing published literature for operation at high temperatures for a transient period of time in oxygen rich environments. ANSYS Fluent 2020R1, and its newly included Volume of Fluid to Discrete Particle (VOF-DPM) Model, is used for CFD simulation of LOx atomisation and vaporisation. The CFD simulation technique is discussed in detail in order to allow the reader to gain knowledge into areas where computational power can be saved while still allowing assessment of trends for conducting relatively quick feasibility reviews e.g. for different chamber configurations. The CFD simulation results are compared with published experimental data and its accuracy when extended to this application is discussed. Results indicate that gasification of LOx within a compact chamber may be feasible if sufficient turbulence, resulting in longer residence times is present providing sufficient time for heat and mass transfer from the continuous phase. Simulations indicate that due to the mixing and gasification process the LOx particles within the chamber that have not entered the gaseous phase are smaller than that from pure atomisation and therefore more susceptible to gasification if injected into the main motor combustion chamber. Results hint at the potential benefit of swirl injection of hot gases to increase residence time and in turn the gasification efficiency, therefore, this is recommended for the topic of future research.
Computational Fluid Dynamics (CFD) simuleringar presenteras i denna studie för superkyld flytande syreförstoftning och förgasning i en underkritisk kammare som arbetar vid SI 1 MPa. Relativt billiga simuleringstekniker har använts och deras noggrannhet utvärderats. Förgasningseffektivitet som förväntas från teorin jämförs med simuleringsresultat och fysisk begränsning utöver detta diskuteras modelleringsberäkningarna. Stötstrålar har använts inom simuleringarna med avsikt att finfördela det inkommande flytande syret, följt av injektion av varm vattenånga vinkelrätt, för att öka turbulent blandning, uppehållstid och i sin tur förväntad förgasningseffektivitet. En beräkningsenhetsanalys för uppvärmningsdynamik ingår också för att belysa begränsningar för kammargeometri som införs genom övergående gränser för snabb oxidation. 316 rostfritt stål och 3D-printad Inconel 718 undersöktes experimentellt för att identifiera deras övergående makroskopiska snabba oxidationsgränser. Denna information kompletterar befintlig publicerad litteratur för drift vid höga temperaturer under en kort tid i syrgasrika miljöer. ANSYS Fluent 2020R1, och dess nyligen inkluderade volym av vätska till diskret partikel (VOF-DPM) -modell, används för CFD-simulering av LOxatomisering och förångning. CFD-simuleringstekniken diskuteras i detalj för att göra det möjligt för läsaren att få kunskap om områden där beräkningskraft kan sparas medan man fortfarande tillåter bedömning av trender för att göra relativt snabba genomförbarhetsgranskningar, t.ex. för olika kammarkonfigurationer. CFD-simuleringsresultaten jämförs med publicerade experimentella data och dess noggrannhet när den utvidgas till denna applikation diskuteras. Resultaten indikerar att förgasning av LOx i en kompakt kammare kan vara möjlig vid tillräcklig turbulens, vilket resulterar i längre uppehållstider är närvarande som ger tillräcklig tid för värme och massöverföring från den kontinuerliga fasen. Simuleringar indikerar att på grund av blandnings- och förgasningsprocessen är LOx-partiklarna i kammaren som inte har gått in i gasfasen mindre än den från ren förgasning och därför mer mottagliga för förgasning om de injiceras i huvudmotorns förbränningskammare. Resultat antyder den potentiella fördelen med virvelinjektion av heta gaser för att öka uppehållstiden och i sin tur förgasningseffektivitet, därför rekommenderas detta för ämnet för framtida forskning.

Abstract:

Modern-day terrorist attacks present a considerable danger for commercial aircrafts. This thesis analyzes potential methods of such attacks with a critical analysis of the most dangerous type: an attack from the outside of the aircraft via a fragmentation missile warhead. Such missiles cause damage to the airframe of the aircraft through fragments created by the explosion. In this thesis, analytical geometry is used to determine the area of the aircraft affected by the fragmentation. The aircraft’s geometry and the fragments’ dispersion are calculated by analytical functions, and the effect of the damage is analyzed. A shooting experiment was also carried out, in which fragments were shot at a reinforced skin panel that was manufactured according to the real design of commercial aircraft. The results of the experiment revealed that only directly hit sections of the structure are damaged. Data obtained by the experiment was then used for the creation and improvement of the model used in the simulation by means of the finite element method. This model is used for the numerical calculation of the damage sustained. Further included in the thesis is an analysis of the change in the load-bearing capacity after such an attack. The relationship between the size of the damage and its effect on the load-bearing capacity of the component as well as the entire structure is defined. First, the effect of component damage is analyzed via the FMEA/FMECA methods. This analysis is then extended using fuzzy logic. Fuzzy logic analysis is based on the determination of the size of the damaged component area and the component’s importance on the structure’s carry loads. Application of the defined approach is described for several parts of an aircraft’s life cycle, including development, operation after the terrorist attack, and assessment of causes after a crash caused by a fragmentation missile warhead.

Abstract:

The space industry and the technological developments regarding space exploration hasn’t been this popular since the first moon landing. The privatization of space exploration and the vertical landing rockets made rocket science mainstream again. While being able to reuse rockets is efficient both in terms of profitability and popularity, these developments are still in their early stages. Vertical landing has challenges that, if neglected, can cause disastrous consequences. The existing studies on the matter usually don’t account for aerodynamics forces and corresponding controls, which results in higher fuel consumption thus lessening the economical benefits of vertical landing. Similar problems have been tackled in studies not regarding booster landings but regarding planetary landings. And while multiple solutions have been proposed for these problems regarding planetary landings, the fact that the reinforcement learning concepts work well and provide robustness made them a valid candidate for applying to booster landings. In this study, we focus on developing a vertical booster descent guidance and control law that’s robust by applying reinforcement learning concept. Since reinforcement learning method that is chosen requires solving Optimal Control Problems (OCP), we also designed and developed an OCP solver software. The robustness of resulting hybrid guidance and control policy will be examined against various different uncertainties including but not limited to wind, delay and aerodynamic uncertainty.
Rymdindustrin och den tekniska utvecklingen av rymdutforskningen har inte varit så populär sedan den första månlandningen. Privatiseringen av utforskningen av rymden och de vertikala landningsraketerna medförde att raketvetenskapen återkom som en viktig huvudfråga igen. Även om det är effektivt att återanvända raketer i form av lönsamhet och popularitet, är denna utveckling fortfarande i sina tidiga stadier. Vertikal landning har utmaningar som, om de försummas, kan orsaka katastrofala konsekvenser. De befintliga studierna i frågan redovisar vanligtvis inte aerodynamikkrafter och motsvarande regulatorer, vilket resulterar i högre bränsleförbrukning som minskar de ekonomiska fördelarna med vertikal landning. Liknande problem har hanterats i studier som inte avsåg boosterlandningar utan om planetariska landningar. Även om flera lösningar har föreslagits för dessa problem beträffande planetariska landningar, det faktum att förstärkningsinlärningskonceptet fungerar bra och ger robusthet gjorde dem till en giltig kandidat för att ansöka om boosterlandningar. I den här studien fokuserar vi på att utveckla en lagstiftning för styrning av vertikala booster-nedstigningar som är robust genom att tillämpa koncepten inom förstärkningsinlärning. Ef- tersom förstärkt inlärningsmetod som väljs kräver lösning av optimala kontrollproblem (OCP), designade och utvecklade vi också en OCP-lösningsmjukvara. Robustheten för resulterande hybridstyrning och kontrollpolicy kommer att undersökas mot olika osäkerheter inklusive, men inte begränsat till vind, fördröjning och aerodynamisk osäkerhet.

Darbe, laikantis prielaidos, jog Irano pasiryžimas tęsti branduolinę programą ir agresyvi valdančiųjų retorika yra tikslingos, nuosekliai vykdomos strategijos dalis, buvo užsibrėžtas tikslas išsiaiškinti, kokio pobūdžio yra Irano strategija: puolamojo ar gynybinio tipo, kas padėtų atsakyti į klausimą, ar Islamo Respublika kelia potencialią grėsmę kitoms šalims (darbe akcentuojant JAV ir Izraelį) ar ne. Irano motyvai vykdyti gynybos ar puolimo strategijas yra, atitinkamai, saugumo siekis bei ambicijų įgyvendinimo siekis. Tiek vienas, tiek kitas motyvas turi tvirtą pagrindimą Irano kontekste bei atitinka dabrtinius Irano veiksmus bei valdančiųjų retoriką. Irane kilusios visuomeninės bei institucinės įtampos yra didelė grėsmė valstybės integralumui, tad Irano branduolinę programą bei agresyvią valdančiųjų retoriką yra logiška sieti su aršios visuomenės mobilizacijos forma. Vis dėlto preziumuojant, kad Irans vykdo gynybos ar puolimo strategiją nukreiptą į išorę, mobilizacija tampa tik taktiniu žingsniu strateginio tikslo link. Iranas yra itin ambicinga šalis. Be to, JAV pajėgoms, esant nepajėgioms stabilizuoti Irako ir Afganistano, Irano galimybės įgyvendinti šias ambicijas vis stiprėja.

Since Islamic Revolution in 1979 relations between Iran and international community are tensed. Though current situation, which could be described as impasse, has emerged just in the 2002, when the scope of Iran’s nuclear capabilities was first made public by the Iranian opposition group. Still the 2005 could be considered as a date, when Iran‘s and international communities relations gained current structure. In the 2005 new president M.Ahmedi-Nejad has been elected and nuclear works were resumed. Whereupon Iran is demonstrating determinacy to continue its nuclear enrichment and officials who are involved in decision making process are using aggressive rhetoric in account to U.S. an Israel. Though mentioned rhetoric is directed towards U.S. and Israel, other interrelated countries have arrogated these signals to themselves. And they were understood completely different: from assessment that their meaning is coincident with Iran’s peaceful purpose declaration to judgement that they are direct menace towards Western world. Consequently the assessment of Iran’s behaviour and intentions became complicated and that happened for several reasons: first, Iran’s rhetoric is controversial – averment that nuclear programme is peaceful logically don’t merge with declared willingness to destroy opponents. Second, rhetoric and behaviour don’t match - peaceful programme doesn’t go with a concealment of nuclear activities. Third, political assessment still rest upon realism postulates that...

Abstract:

This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash. Finally, I examine the difficulty of talking about boundaries of various kinds, such as temporal, spatial and functional. The essay also provides a discussion on possible ways to continue research on this topic.

This Master Thesis is focused on analysis of media response to editions Fresh and Raketa of publishing house Labyrint in the context of history of publishing practice in the Czech Republic in the nineties. It also discusses contemporary literature for children and youth. Thesis studies critical media response to three particular books from studied editions Tajemství oblázkové hory by Bára Dočkalová, Robinson by Petr Sís and Plyš by Michal Hvorecký. Novel Plyš by Michal Hvorecký was covered the most in the media. The smallest number of articles was published about Tajemství oblázkové hory by Bára Dočkalová. Even though it was nominated for Magnesia Litera Award, it did not win the price in the end. The closing part focuses on a unique project by publishing house Labyrint, a magazine for children called Raketa. Media attention is focused on creators of magazine, either it is the owner of publishing house Labyrint Joachim Dvořák or its chief editors Johana Švejdíková and Radana Litošová. Critical reflection is rare, there are mostly short notes recommending buying the magazine or describing a new issue. There is a broad spectrum of media chosen for this analysis, from news media to cultural and literary periodical such as Tvar, Host, A2 and catalog Nejlepší knihy dětem.

Abstract:

The thesis deals with the former Bush's plan of the so-called third pillar of the American missile defense system in Poland and Czech republic. We demonstrate on this topic the value of several key (neo)realist theoretical concepts. Specifically, the exact types and functioning of security dilemmas are analyzed in the framework of American-Russian, American-Iranian and American-Czech/Polish relations. The thesis also illustrates the importance of related modalities of deterrence and shows, which states and how balanced the US. In addition to that, attention is paid to the question whether the "shield" was motivated by defensive realist worries about security or rather by offensive realist struggle for power and gains at the expense of others.
