Inom många tillämpningar används konforma avbildningar för att transformera tvådimensionella områden till områden med enklare utseende. Ett exempel på ett sådant område är en kanal av varierande tjocklek begränsad av en kontinuerligt deriverbar kurva. I de tillämpningar som har motiverat detta arbete, är det viktigt att dessa egenskaper bevaras i det område en approximativ konform avbildning producerar, men det är också viktigt att begränsningskurvans riktning kan kontrolleras, särkilt i kanalens båda ändar. Denna avhandling behandlar tre olika metoder för att numeriskt konstruera konforma avbildningar mellan ett enkelt standardområde, företrädesvis det övre halvplanet eller enhetscirkeln, och ett område begränsat av en kontinuerligt deriverbar kurva, där begränsningskurvans riktning kan kontrolleras, exakt eller approximativt. Den första metoden är en utveckling av en idé, först beskriven av Peter Henrici, där en modifierad Schwarz-Christoffel-avbildning avbildar det övre halvplanet konformt på en polygon med rundade hörn. Med utgångspunkt i denna idé skapas en algoritm för att konstruera avbildningar på godtyckliga områden med släta randkurvor. Den andra metoden bygger också den på Schwarz-Christoffel-avbildningen, och utnyttjar det faktum att om enhetscirkeln eller halvplanet avbildas på en polygon kommer ett område Q i det inre av dessa, som till exempel en cirkel med centrum i origo och radie mindre än 1, eller ett område i övre halvplanet begränsat av två strålar, att avbildas på ett område R i det inre av polygonen begränsat av en slät kurva. Vi utvecklar en metod för att hitta ett polygonalt område P, utanför det Omega som man önskar att skapa en avbildning för, sådant att den Schwarz-Christoffel-avbildning som avbildar enhetscirkeln eller halvplanet på P, avbildar Q på Omega. I båda dessa fall används tangentpolygoner för att numeriskt bestämma den önskade avbildningen. Slutligen beskrivs en metod där en av Don Marshalls så kallade zipper-algoritmer används för att skapa en avbildning mellan det övre halvplanet och en godtycklig kanal, begränsad av släta kurvor, som i båda ändar går mot oändligheten som räta parallella linjer. / In many applications, conformal mappings are used to transform two-dimensional regions into simpler ones. One such region for which conformal mappings are needed is a channel bounded by continuously differentiable curves. In the applications that have motivated this work, it is important that the region an approximate conformal mapping produces, has this property, but also that the direction of the curve can be controlled, especially in the ends of the channel. This thesis treats three different methods for numerically constructing conformal mappings between the upper half-plane or unit circle and a region bounded by a continuously differentiable curve, where the direction of the curve in a number of control points is controlled, exact or approximately. The first method is built on an idea by Peter Henrici, where a modified Schwarz-Christoffel mapping maps the upper half-plane conformally on a polygon with rounded corners. His idea is used in an algorithm by which mappings for arbitrary regions, bounded by smooth curves are constructed. The second method uses the fact that a Schwarz-Christoffel mapping from the upper half-plane or unit circle to a polygon maps a region Q inside the half-plane or circle, for example a circle with radius less than 1 or a sector in the half--plane, on a region Omega inside the polygon bounded by a smooth curve. Given such a region Omega, we develop methods to find a suitable outer polygon and corresponding Schwarz-Christoffel mapping that gives a mapping from Q to Omega. Both these methods use the concept of tangent polygons to numerically determine the coefficients in the mappings. Finally, we use one of Don Marshall's zipper algorithms to construct conformal mappings from the upper half--plane to channels bounded by arbitrary smooth curves, with the additional property that they are parallel straight lines when approaching infinity.

The subject of the diploma thesi is the design and assessment of the pavilions supporting structure for exhibition and other purposes. The building is located close to Zlin. Preliminary designs of supporting structure were created. One of these was selected and detaileddesigned and assessed. Generallythere are two structures that are extended between themselves. A design and assessment of the entrance portal for the exhibition pavilion was created. The entrance portal is an atypical structure that was created from a combination of hyperboloid and cylinder. The entire portal is formed of welded parts and it is completely from glass. The entrance portal has a variable height, where the highest point is 8,258m. The entrance portal is 20,394m long and has a variable width, where the largest width is 12,000m. The exhibition hall, which is located behind the entrance portal was designed from flat arched truss trusses. The arched trusses are made of several radii and hasa overall impression of an elliptical truss. The trusses have a range 37,000m and they are axially distant 6,000m. The height of the arched trusses is 10.530m. In the leading position of the construction were designed pillars and construction for possible connection of the entrance portal, or for the location of the gate system. Whole construction of the exhibition pavilion, without the entry portal, is 54,000m long and 37,000m wide. The built-up area of both structures is approximately 2200m2. Construction are designed according to normative requirements of CSN EN for limit state of load capacity and usability. The main material of the supporting structural parts was used S355JR steel.

Icing is an important problem, which often leads to emergency situations in northern countries. The reduction of icing requires a detailed understanding of this process. In this work, we report on a systematic investigation of the effects of geometry and chemical properties of surfaces on the formation of an ice layer, its properties, and thawing. We compare in detail icing and ice thawing on flat and rough hydrophilic and hydrophobic surfaces. We also show advantages and disadvantages of the surfaces of each kind. We demonstrate that water condenses in a liquid form, leading to the formation of a thin continuous water layer on a hydrophilic surface. Meanwhile, separated rounded water droplets are formed on hydrophobic surfaces. As a result of slower heat exchange, the freezing of rounded water droplets on a hydrophobic surface occurs later than the freezing of the continuous water layer on a hydrophilic one. Moreover, growth of ice on hydrophobic surfaces is slower than on the hydrophilic ones, because ice grows due to the condensation of water vapor on already formed ice crystals, and not due to the condensation on the polymer surface. Rough hydrophobic surfaces also demonstrate a very low ice adhesion value, which is because of the reduced contact area with ice. The main disadvantage of hydrophobic and superhydrophobic surfaces is the pinning of water droplets on them after thawing. Flat hydrophilic poly(ethylene glycol)-modified surfaces also exhibit very low ice adhesion, which is due to the very low freezing point of the water–poly(ethylene glycol) mixtures. Water easily leaves from flat hydrophilic poly(ethylene glycol)-modified surfaces, and they quickly become dry. However, the ice growth rate on poly(ethylene glycol)-modified hydrophilic surfaces is the highest. These results indicate that neither purely (super)hydrophobic polymeric surfaces, nor ‘‘antifreeze’’ hydrophilic ones provide an ideal solution to the problem of icing.

Sammanfattning Titel: Billigt eller dyrt, udda eller jämt? - Hur prisprecisionseffekten påverkar Willingness to pay Nivå: Examensarbete på Grundnivå (kandidatexamen) i ämnet företagsekonomi. Författare: Lovisa Axenfalk Pettersson och Wilhelm Ericsson. Handledare: Jonas Kågström. Datum: 2018 - Maj. Syfte: Syftet är att undersöka hur prisprecisionseffekten i samband med Willingness to pay påverkar bostadstransaktioner. Metod: Kvantitativ metod, enkäter med experimentella inslag. Resultat och slutsats: Denna studies resultat visar att när det kommer till priser på bostäder, är det inte enbart priset som påverkar köpet och WTP. Gällande det marknadsförda pris som lockar flest spekulanter, bör det antingen vara avrundat pris eller just below pris. Det mest ärliga marknadsmässiga priset är avrundat pris. Ett precist pris är det utgångspris, som anses vara satt av en seriös fastighetsmäklare och visar att fastighetsmäklaren är kunnig och sätter ett seriöst pris utifrån vad bostaden faktiskt är värd. Gällande vad som leder till det högsta slutpriset, kan det vara avrundat pris, precist pris samt just below pris. Varför resultatet av slutpriset skiljer sig åt är beroende på situationen på marknaden och tillgänglig information för köparen. Examensarbetets bidrag: Denna studie har bidragit med att skapa en ökad förståelse till personer som är delaktiga i en köpprocess utifrån prisprecisionseffektens prissättningar. Vidare är bidraget att människor påverkas av tillgänglig information, vilket påverkar köparens WTP och vad köpare anser om olika priser. Med kunskap från denna studie kan köpare av bostäder få en bättre förståelse för hur det marknadsförda utgångspriset kan påverka köparens WTP av bostaden de är intresserad av att köpa och den bostadens slutpris. Förslag till fortsatt forskning: Studien fastställer att det finns flera möjligheter till fortsatt forskning. Det skulle kunna vara att studera prisprecisionseffekten i en verklig miljö. Att studera hur ankareffekten och prisprecisionseffekten påverkar varandra. Väva in andra prispåverkande faktorer än bara själva priset. Samt att vända perspektiv och utgå från säljaren istället. Nyckelord: Prisprecisionseffekten, WTP - Willingness to pay, avrundat pris, precist pris, just below pris, utgångspris och bostadstransaktioner. / Abstract Title: Cheap or expensive, odd or even? - How the price precision effect, affects willingness to pay Level: Final assignment for Bachelor Degree in Business Administration. Author: Lovisa Axenfalk Pettersson and Wilhelm Ericsson. Supervisor: Jonas Kågström. Date: 2018 - May. Aim: The aim is to further investigate how the price precision effect associated with willingness to pay affects sales of real estate transactions. Method: Quantitative method through a survey with experimental elements. Result and conclusion: The results in the study indicates, regarding prices on the housing market, that it is not only the price that affects pursues and WTP. Regarding the marketed list price, which attracts the most potential buyers, they should either be a rounded or just below price. The most honest market price is a rounded price. A list price set at a precise price, is considered to be listed from a serious real estate broker. It also indicates that the real estate broker is knowledgeable and puts a serious price based on what the residence is actually worth. To get the highest selling price, it can be all of the price precision effect prices, rounded price, precise price or just below price. Why the result of the highest selling price differ, is depending on the situation on the market and available information for the buyer. Contribution of the thesis: The contribution for this study has been to create an increased understanding about the price precision effect and its prices for the persons involved in a buying process. Furthermore, the contribution is that people are influenced by available information, affecting the buyer's WTP and what buyers consider about different prices. With knowledge from this study, buyers can gain a better understanding of how the marketed list price may affect the buyer's WTP for the real estate they are interested in buying and its final selling price. Suggestion for future research: To summarize the possibilities for future research this paper suggests; to analyze the price precision effect from the sellers point of view. To analyze the price precision effect in a real setting instead, where actual transactions are being made. To further investigate the ratio between the anchoring effect with the price precision effect, and how they affect each other. The final suggestions for future research is to involve other aspects into the price precision effect, despite only the price, because it is not only the price that affects the house buying market. Keywords: Price precision effect, WTP - willingness to pay, rounded price, precise price, just below price, list price and real estate transaction.

De acordo com a literatura (ALCÂNTARA, 1998; RESTREPO, 2011), a aquisição das vogais anteriores arredondadas do francês por aprendizes adultos brasileiros mostra-se uma tarefa complexa, tanto em termos de percepção quanto de produção. Diante disso, neste trabalho, procuramos contribuir ao entendimento dessa complexidade e fomentar os poucos estudos brasileiros envolvendo sujeitos proficientes em francês (L2) e a aquisição dos referidos sons. Desse modo, buscamos responder de que maneira os locutores brasileiros adultos, proficientes em francês (L2), lidam com sons alheios à fonologia da sua LM, no que concerne à sua percepção e produção. Para tanto, objetivamos, especificamente, detectar o grau de acuidade com o qual as vogais-alvo são identificadas e discriminadas pelas participantes avaliadas, bem como definir o comportamento acústico desses sons em sua fala, de modo que seja possível explicar uma provável produção autêntica dos segmentos franceses investigados em função de as informantes os identificarem, discriminarem e articularem. Diante disso, dois grupos de informantes participam desta pesquisa: o composto pelas brasileiras, três professoras-pesquisadoras de FLE no ensino superior público brasileiro, residentes em Pelotas/RS, e o formado por uma locutora francesa nativa, da região parisiense, a qual constitui o grupo controle e cujos dados se somam aos disponíveis na literatura. Para a coleta dos dados de produção em ambos os grupos, foram elaborados quatro experimentos, três envolvendo vogais orais francesas e o outro vogais orais do PB, as quais se encontravam em palavras e logatomas do francês e do PB, produzidos dentro de frases-veículo. Para a coleta dos dados de percepção relativos às vogais do francês, foram construídos quatro experimentos, dois testes de identificação e dois testes de discriminação. A metodologia utilizada na construção desses experimentos foi baseada, em parte, naquela elaborada por Restrepo (2011), com adaptações para atender aos objetivos específicos deste trabalho. As coletas ocorreram em ambiente acústico controlado (cabine acústica), com a utilização de um gravador digital Zoom H4N e de um par de fones de ouvido modelo AKG K 44. Os dados coletados foram analisados acústica e estatisticamente, por meio dos softwares Praat (versões 6.0.08 e 6.0.19) e SPSS Statistics (versão 17.0), respectivamente. Os resultados obtidos, interpretados à luz do modelo HipCort (MCCLELLAND et al.,1995), um modelo dinâmico de formação da memória e do aprendizado, confirmam nossa tese do potencial êxito de nossas informantes na aquisição dos sons investigados, pois identificam, discriminam e produzem acuradamente as vogais anteriores arredondadas do francês, demonstrando terem se distanciado de uma possível influência de sua LM. Os resultados alcançados contribuem, portanto, para se refutar a existência da atuação de restrições biológicas ligadas a uma concepção de aquisição da linguagem calcada nos pressupostos do paradigma simbólico, indo ao encontro de estudos que evidenciam a possibilidade de aprendizes tardios apresentarem um nível de competência fonético-fonológica em L2 comparável àquele do falante nativo. / This study investigates the acquisition of front rounded vowels [y], [q], and [E] of French by adult female speakers who are proficient in French (L2). According to the literature (ALCÂNTARA, 1998; RESTREPO, 2011), the acquisition of front rounded vowels of French by Brazilian adult learners is a complex challenge, either in terms of perception or in terms of production. From this point, in this study we sought to contribute to the understanding of this complexity and develop the not many Brazilian studies involving individuals with proficiency in French language (L2) and the acquisition of its sounds. Thus, our challenge was to answer in what way adult Brazilian speakers, with proficiency in French (L2), deal with foreign sounds, different from the ones of their ML phonology, when it comes to their perception and production. Therefore, we aimed to detect, specifically, the level of perceptiveness with which the target vowels are identified and distinguished by the considered participants, as well as defining the acoustic behaviour of these sounds in their speaking, in a possible way to explain a probable authentic production of the investigated French segments according to the identification, distinction, and articulation of the participants. Then, two groups of volunteers participated in this research: one counts with the presence of three Brazilian women, professors and researchers of FFL in superior public education, residents in Pelotas/RS; the second group is formed by a native French speaker from Parisian region, who participates of the control group, which data is added to the one available in literature. For the collecting of data of production in both groups, four experiments were elaborated, three involving French oral vowels, and the last one involving oral vowels of BP, which were found in words and non-words from French and BP, produced inside of carrier sentences. For the collecting of information of perception related to the French vowels, four experiments were formed, two tests of identification, and two tests of distinction. The methodology used in the construction of these experiments was based on the one elaborated by Restrepo (2011), with adaptions to attend to the specific objectives of this study. The collection of the material occurred in a controlled acoustic environment (acoustic compartment), with the use of a digital recorder Zoom H4N and a pair of earphones model AKG K 44. The collected data was analysed acoustically and statistically with the softwares Praat (6.0.08 and 6.0.10 versions) and SPSS Statistics (17.0 version), respectively. The results achieved were interpreted with the HipCort model (MCCLELLAND et al, 1995), a dynamic model of formation of memory and learning. They confirmed our thesis of the potential outcome of our participants in the acquisition of the investigated sounds, because they could identify, distinguish, and produce accurately the front rounded vowels of French, demonstrating the distance of a possible influence from their ML. The results contribute, so, to refute the existence of an operation of biological restrictions connected to a conception of acquisition of language based on the presupposition of the symbolic paradigm, which meets the studies that evince the possibility of late learners to present a level of phonetic and phonologic competences in L2 comparable to the native speaker.

This diploma thesis contains design documentation of of a new hotel in Lipno nad Vltavou near the Lipno reservoir. It is a building with three floors, a non-residential attic and a partial basement, where there will be underground garages for guests and technical facilities of the hotel. The building will accommodate a total of 70 people in 27 hotel rooms. The building is also equipped with a hotel restaurant, gym, massages and a sauna. The structure of the building is designed as masonry system manufactured by Heluz, supplemented by a reinforced concrete skeletal system, outside walls have a contact thermal isulation. Only the basement walls are made of permanent concrete framework. Horizontal structures are made of reinforced concrete monolithic slabs. The roofing is designed with two rounded opposite counter roofs in two levels raised by roof trusses and further supplemented by a flat vegetation roof. The modern look is underlined by the materials used. These include the glazed railings of balconies or terraces and their location, as well as the combination of white facades with facade cladding made of fiber-cement boards in imitation wood. The design was concentrated on high user comfort and overall modern concept of the hotel.
