Starting a thesis with intention and ambitious to invent a future mobility for Southeast Asia region, one of the fastest growing region in the world. I was so passionate about what is the future mobility that very compatible to South-East Asia consumer that face a hot weather and humidity climate in whole year. Recently, the car that we produce whether in local manufacturing or imported car are not very compatible for the current environment since the climate is change dramatically in kind of temperature which massive impact in material usage in the vehicle and our daily life. By this platform, my main priority is to find a best solution by doing a research and problem´s analysis about the real situation and for a long period of time. Then, I was began the project by summarize the concept based on the research analysis. Design research, brand and background analysis, ideation sketches, studying an overall form by using clay and 3D digital modelling and also advanced visualization were the main methods that implemented during this project. The result is GEMILANG Concept, designed a future vehicle which have semi-autonomous drive mode for ASEAN ambition and actual need throughout in developing countries. The concept is considered between a climate change in this region and proposes a highly efficient in how to implement the best use of natural resources that able to stand in extreme climate particularly in this region and innovative solution between tradition, need and technology.

Solid-state lasers are capable of providing versatile output characteristics with greater flexibility compared to other popular laser systems. Lasing action has been achieved in many hundreds of solid-state media, but Nd-ion doped gain media are widely used to reach high power levels with short pulses. In this work, commercially available Nd:KGW crystal served as a gain medium to achieve pulsed operation at 1067 nm. This laser crystal offers large stimulated emission crosssection and gain bandwidth which facilitates generation of high peak power pulses in the picosecond regime. The KGW crystal is monoclinic and biaxial in structure, and anisotropic in its optical and thermal properties. Due to poor thermal conductivity, this crystal can be operated within a limited power range before crystal fracture takes place. To reduce the amount of heat deposited in the gain media, we introduced a new pumping wavelength of 910 nm which reduces the quantum defect by more than 45%. Continuous-wave laser operation was optimized to operate in mode-locked regime. In order to achieve short light pulses from the continuous-wave laser, one of the end mirrors was replaced by a semiconductor saturable absorber mirror (SESAM) to generate 2.4 ps pulses at a repetition rate of 83.8 MHz. An average output power of 87 mW was obtained at lasing wavelength of 1067 nm and the beam was nearly diffraction limited with M^2 < 1.18. The peak power of the generated pulses was 427 W and energy of each pulse was >1 nJ. Pumping the crystal at longer wavelength (910 nm) reduced the thermal lensing of the crystal by half when compared to conventional pumping at shorter wavelength (808 nm). To the best of our knowledge, this is the first time passive mode-locking of a Nd:KGW laser was explored using the pump wavelength at 910 nm. / February 2017

This study aims to two problematic aspects of the Phrygian mode: a. the development of a harmonic pattern at the cadence that differs from that of the other modes and of the major and minor modes as well; b. the observation that the Phrygian scale inverts all of the intervallic properties of the Major scale. The result of these two observations is that when the reductive techniques of Heinrich Schenker are applied in the Phrygian repertory, melodic and harmonic properties are brought into conflict with each other. However, application of alternative models of the Ursatz developed by Lori Burns has certain benefits for demonstrating musical properties in the Phrygian repertory.

Face à des situations d’apprentissage de nombreux processus cognitifs peuvent être mis en œuvre par les apprenants en vue de créer de nouvelles traces mnésiques (mémorisation d'exemplaires ou abstraction de connaissances notamment). Depuis plusieurs décennies de nombreuses recherches ont mis en évidence que la mise en œuvre privilégiée de l’un ou l’autre de ces processus est fonction de différents paramètres : particularités interindividuelles, niveaux des apprenants, oucaractéristiques de la tâche. Notre thèse porte sur ce dernier point : sur les liens entre certaines caractéristiques du matériel à apprendre et les processus cognitifs des apprenants. Plus particulièrement, nous nous intéressons à la question de l'impact du mode de présentation de problèmes, étudiés par des apprenants en vue de progresser. Si de nombreux travaux ont déjà porté sur la structuration interne des problèmes et leur lien avec les mécanismes cognitifs (cf. Sweller et al, 2000), très peu de recherches ont porté sur les effets du mode de présentation et d'organisation de plusieurs problèmes de difficultés similaires ou différentes. C'est pourquoi nous avons mené ce travail de recherche. Afin de mieux comprendre les interrelations entre la résolution de problèmes et l'apprentissage de connaissances qui peut en découler. / No english summary

This study attempts to find a correlation between commuting modes in Washington DC and characteristics of the city and the people that they serve. It investigates why some census tracts have experienced increases in the commuting share of alternative transportation, such as public transit, walking, and bicycling, while others haven't. Findings demonstrate that demographic variables such as percent Hispanic and foreign born were the strongest predictors of change in commute mode share followed by distance to train station. Land use variables demonstrated weak correlations with variations in mode share due most likely to a lack of density gradient within the study area. The creation of variables to determine land use mix by census tract posed technical challenges as well. Recommendations include policy addressing rising demand for more diverse transportation systems be implemented and further research be conducted on creating more accurate land use variables to include in the model.

The object of this thesis is Crown Princess Victoria's dress choices in her royal duties, primarily ceremonies, during the past three years based on visibility in media. The aim of the study is to investigate whether the Crown Princess has used fashion in a different way than other royals in history and today. Fashion scientific I have also examined how the Crown Princess fashion choices relates to her brand, an my studies has focused on subjects such as nationality, power, style, class and popular appeal. The questions relates to the Crown Princess' conscious clothing priorities, her wedding dress and the fashion effects on the Crown Princess' brand. The material includes: field observation at the wedding dress exhibition at the Royal Palace, interviews at the Royal Court, surveys of fashion magazines and a collection of photo material. The varied material, its scope and the time constraints have made me choose the ethnological method "the moving searchlight" as a flexible and systematic processing of the material based upon the overall research questions. I have used the theories by Erving Goffman and Pierre Bourdieu throughout the analysis with focus on use of Goffman ́s theory taken from the theater and enactments and Bourdieu with his theories in sociology as the visibility of taste in practices. The results from my analysis show that there are differences in the way the Crown Princess expresses her role in comparison with other historical and contemporary royals. These differences are mainly visible in her choice of clothing from a sustainability perspective but also based on the concept of popular appeal. The similarities are those concerning national origin in her choices of clothing. I have also come to the conclusion that academic analytical methods in her royal fashion choices, on the basis of history and deep academic analysis, could become key success factors in the developing of the Crown Princess style in terms of visibility and ultimately strengthening her brand for Sweden, The Royal Family and the Royal Court.

La thématique centrale de notre thèse concerne l’étude du transfert de connaissances acquises dans des situations virtuelles (environnements virtuels ou EVs) vers des situations de la vie quotidienne. Plus particulièrement, nous nous sommes intéressés à l’effet du mode de navigation en EV (i.e., avec ou sans joystick) sur la qualité du transfert de connaissances spatiales (un parcours à apprendre). La littérature relative à cet effet révèle des résultats contradictoires, et nous proposons d’apporter des éléments d’explication en examinant les interactions possibles entre le mode de navigation et d’autres facteurs susceptibles d’affecter les performances. Ainsi l’effet du mode de navigation sur le transfert virtuel-réel a été testé en interaction avec les facteurs suivants : la fidélité visuelle de l’EV (Exp. 1), la complexité informationnelle du parcours à apprendre (Exp. 2) et le délai de rétention (Exp. 3 et 4). Le transfert virtuel-réel et les connaissances spatiales ont été mesurés à l’aide de trois tâches de rappel : Wayfinding (i.e., reproduction du parcours appris dans la réalité), dessin à main levé du parcours et classification de photos dans l’ordre chronologique. Nos résultats montrent que l’impact du mode de navigation sur la qualité du transfert n’est pas le même selon les facteurs manipulés (i.e., fidélité visuelle, complexité du parcours et délai de rétention) et selon la tâche de rappel utilisée. Ces résultats nous ont permis de préciser le lien entre exploration active et systèmes représentationnels notamment à la lumière des théories sur le traitement cognitif d’informations spatiales (i.e., le modèle L-R-S et l’approche des graphes). Ces résultats permettent également de préciser les situations favorisant le transfert virtuel-réel, ce qui offre un intérêt particulier dans les enjeux notamment d’utilisation de la réalité virtuelle dans le diagnostic et/ou la réhabilitation cognitive. / The main theme of this thesis is the transfer of knowledge acquired in virtual situations (virtual environments or VEs) to situations in everyday life. We focused particularly on the effect of the navigation mode in VE (i.e., with or without joystick) on the quality of the transfer of spatial knowledge (learning a pathway). Previous publications on this effect presented contradictory findings and our aim was to elucidate this situation by examining possible interactions between the navigation mode and other factors likely to affect performance. Consequently, the effect of the type of movement control on virtual-real transfers was tested in interaction with the following factors: the visual fidelity of the VE (Exp. 1), the informational complexity of the route to be learned (Exp. 2), and retention delay (Exp. 3 and 4). Virtual-real transfers and spatial knowledge were measured using three recall tasks: Wayfinding (i.e., reproducing the route in the real world), freehand drawing of the path, and organizing photos in chronological order. Our findings revealed that the impact of the movement control on the transfer varied according to the factors manipulated (i.e., visual fidelity, route complexity, and retention delay), as well as the recall task used. These results clarified the connection between active exploration and representational systems, especially in light of theories on the cognitive processing of spatial information (i.e., the L-R-S model and the graph approach). These results also identified situations that facilitated virtual-real transfer, which is of particular interest when virtual reality is to be used in cognitive diagnosis and/or rehabilitation.

Children’s everyday travel and parents’ choices of mode of travel.   Karola Fors, Department of Geography, Umeå University, Sweden     Abstract The purpose of this interview study was to investigate parents’ choice of travel mode for their child and behavioral change towards sustainable travel. The study was conducted in Umeå, a city in northern Sweden, in March and April 2019. The interview focused on parents describing from travel journals one week of their child’s travel arrangements. The analysis of the interviews was based on The Theory of Planned Behavior (Azjen 1991). Attitude, perceived Control and Norms, lead to the Intentions to change behavior and this is described by Azjen (1991) and is also noticeable in the study conducted. Mobility Management projects in the municipalities aim to increase the use of sustainable travel modes. The parents described that the reasons for choosing their child’s mode of travel was time, distance, safety and weather conditions as determined by seasons. Some described practical reasons, age and maturity. None of the parents described health and environmental concerns when describing the choice of travel mode. The travel journals showed that most commutes were made by car, especially concerning trips to leisure activities. The intention to make changes towards sustainable travel modes varied in accordance to attitude, perceived control and norms described. Some described the child biking or taking the bus more often, others described future trips mainly by car. The norms in society is a challenge for Mobility Management projects in establishing habits towards sustainable travel modes.

The objective of this thesis is to present a theoretical and experimental investigation of the dynamics of micro and nano-electromechanical systems electrothermally tuned and electrostatically actuated, and explore their potential for practical applications. The first part of the dissertation presents the tuning of the frequency of clamped-clamped micro and nano-resonators, straight and curved. These resonators are electrothermally or electrostatically tuned. The effect of geometric parameters on the frequency variation is investigated experimentally and theoretically using a reduced order model based on the Euler-Bernoulli beam theory. High tunability is demonstrated for micro and nano beams, straight and initially curved. The second part discusses the dynamical behavior of a curved (arch) beam electrothermally tuned and electrostatically actuated. We show that the first resonance frequency increases up to twice its fundamental value and the third resonance frequency decreases until getting very close to the first resonance frequency triggering the veering phenomenon. We study experimentally and analytic ally, using the Galerkin procedure, the dynamic behavior of the arch beam. Next, upon changing the electrothermal voltage, the second symmetric natural frequency of the arch is adjusted to near twice, three times, and four times the fundamental natural frequency. This gives rise to a potential two-to-one, three-to-one, and four-to-one autoparametric resonances between the two modes. These resonances are demonstrated experimentally and theoretically. The third part of the dissertation is concerned with the incorporation of the electrothermally tuned and electrostatically actuated microresonators into potential applications: filtering and sensing. First, we experimentally prove an exploitation of the nonlinear softening, hardening, and veering phenomena of an arch beam, to demonstrate a flat, wide, and tunable bandwidth and center frequency by controlling the electrothermal actuation voltage. Second, a pressure sensor based on the convective cooling of the air surrounding an electrothermally heated resonant bridge is demonstrated experimentally. The concept is demonstrated using both straight and arch microbeam resonators driven and sensed electrostatically. The change in the surrounding pressure is shown to be accurately tracked by monitoring the change in the resonance frequency of the structure.
