[pt] O presente estudo se refere ao campo de partículas deformáveis, em particular às bolhas de ar em líquidos de diferentes propriedades físicas. Estudando a passagem de bolhas de ar em interfaces líquido-líquido, constatou-se que as bolhas formadas na água e passando para os líquidos superiores (de densidade inferior), são envolvidas por uma película de água de espessura não uniforma, para diâmetros equivalentes na faixa de 2,5 a 5,7mm. Os fluidos superiores possuem viscosidade cinemática na faixa 1,2 e 55,0 cs e tensão interfacial com a água entre 13,0 e 32,0 din/cm. A influência dessa película no comportamento das bolhas de ar é acentuada quanto a: forma, pulsação de forma, trajetória, velocidade terminal. Constatou-se que a espessura média dessa película aumenta com o diâmetro equivalente e varia com as propriedades físicas dos fluídos superiores. Particular importância da película se nota quando o fluido superior tem pequena viscosidade cinemática: as bolhas de forma irregular são arredondadas pela película, de maneira que, para as bolhas maiores, apesar do peso da película a velocidade é maior em comparação com a de uma bolha sem película. Com o aumento da dimensão das bolhas, um diâmetro é atingido, para o qual há o rompimento da película com o consequente desprendimento da água em forma de gota; esse diâmetro parece variar pouco com as propriedades dos fluidos superiores. O campo de pesquisa do presente estudo apresenta inúmeras sugestões, e algumas estão sendo estudadas presentemente. / [en] The present study refers to the case of deformable particles, in particular to air bubbles in liquids of different physical properties. On studying the passage of air bubbles through liquid-liquid interfaces, it was verified that bubbles, formed in water and rising in the upper liquid (low density), were surrounded by non-uniform water film when the bubbles had na equivalent diameter between 2,5 and 5,7mm. The kinematic viscosity of the upper liquids ranged from 1,2 to 55,0 centistokes, and the interfacial tension from 13,0 to 32,0 din/cm. The presence of that film affects the form, trajectory and terminal velocity of the air bubbles. It was verified that the average film thickness increases with the equivalent bubble diameter and changes with the physical properties of the upper liquids. Interesting phenomena were noted when the upper liquid viscosity was low – the film caused the irregular air bubbles to be changed to a spherical form, in such a way that the larger bubbles, depite film weight, had a greater terminal velocity than non filmed bubbles. As the bubble dimension was increased, a limit was found, at which the water film broke, and a drop was formed. The critical diameter seems not to be affected by the properties of the upper liquids. Research in this Field presents several possibilities, which are now under study.

En utforskande och kvalitativ förstudie kring användningen av skönhetsfilter på Instagram för att förstå unga kvinnors åsikter och tankar kring ämnet. Baserat på Leon Festingers teorier kring social jämförelse, Erving Goffmans impression management och Roger Caillois mimicry så försöker vi förstå vad skönhetsfilter gör med oss och varför vi använder det, tillsammans med användningen av augmented reality och skapandet av ett eget skönhetsfilter. Förstudien utfördes med hjälp av ett framtaget skönhetsfilter som testades på åtta kvinnor i åldrarna 20-24, uppdelat i fyra mindre fokusgrupper. I fokusgrupperna diskuterades även generella inställningar till skönhetsfilter och sociala medier. Resultaten från fokusgrupperna visade på en liten direkt effekt av att använda skönhetsfilter, men att dessa hade haft större effekt på deltagarna tidigare i livet. De effekter som uppstod var en hypermedvetenhet om sitt utseende och en något sämre kroppsbild bland deltagarna. / <p>Det finns övrigt digitalt material (t.ex. film-, bild- eller ljudfiler) eller modeller/artefakter tillhörande examensarbetet som ska skickas till arkivet.</p>

This study investigates the current state of the intersection between Augmented Reality(AR) and education, with a focus on improving statistical math learning in higher education through the application of AR and data modeling. Our research aims to answerthe question: "How can AR enhance math learning in the field of statistics in higher education?" We follow the method of Design and Creation to develop an open-source ARapplication tailored for an experimental study to assess the impact of AR on learning.In addition to the experimental aspect, this study includes a comprehensive semistructured literature review, where we analyze findings from prior research and utilize theirdata to validate our own results. Our research indicates that AR has a positive impacton the average student. It enhances spatial intelligence, makes learning more enjoyable,and is an effective tool for teaching complex topics. However, we acknowledge certainlimitations in implementing AR in education with current technology such as affordabilityand the lack of training necessary to employ these technologies. Despite these challenges,we conclude that the investment in making AR accessible and affordable for all studentsis worthwhile due to its significant positive effects on learning outcomes for mathematicalstatistics

Tidigare forskning visade att användandet av för många diciplinerande tillrättavisningar kan hämma barns möjligheter till utveckling och lärande samt vikten av att ha gemensamt förhållningsätt hos förskollärare. Syftet med studien är att bidra med kunskap om fenomenet tillrättavisningar i förskolans utbildning och hur tillrättavisningar används och motiveras av verksamma förskollärare. I en kvalitativ studie deltog åtta förskollärae från olika förskolor och under olika huvudmannaskap. Åtta individuella semistrukturerade intervjuer genomfördes,samtliga intervjuer ljudinspelades och transkriberades. Resultatet analyserades utifrån Michel Foucaults maktteori. Resultatet svarar på studiens tre forskningsfrågor; Vad ses som en tillrättavisning i förskolan? I vilka sammanhang används tillrättavisningar i utbildningen? samt vilka konsekvenser användandet av tillrättavisningar kan ge i förskolan? I resultatet framkom olika former av tillrättavisningar. Det framkom även att tillrättavisningar var kontextbundna och att "rätt" tillrättavisning skulle användas i "rätt" sammanhang eller situation. Genom att använda tillrättavisningen "rätt" kan konsekvensen av tillrättavisningen bli olika: Förslag på vidare forskning skulle kunna vara att undersöka hur barnet själv upplever en tillrättavisningur barnets eget perspektiv.

This report covers the Master thesis work conducted at ABB Robotics in Västeråsduring the spring of 2022. The purpose of the thesis was to evaluate how VirtualReality (VR), Augmented Reality (AR) and Additive Manufacturing (AM) can beused in the product design process for designs in Production Engineering. This is tominimize the time between design iterations to assure that the delivered design livesup to its expectations. During the thesis work, different software and equipments have been investigated tofind the appropriate solution for the different types of product designs scenarios. Todo this, the process was applied on the actual product design problem also included inthis thesis work, by involving the end user in the design reviews. During the designreviews different testers had the possibility to visualize and interact with the design.The function of the product design was also examined by using a modular basedproduct structure consisting of the moving and static parts in sub-assemblies. WithAM, the usage of prototypes depending on its purpose was investigated. The result of this thesis is a process consisting of a concept review with VR/ AR, aprototype step where AM is included and a final review with either VR or AR.
