This thesis is based on three projects that deal with vertical III-V semiconductor devices. The work spans over basic research as well as more applied aspects of III-V semiconductor technology. All projects have in common that they rely on advanced epitaxial growth to form the starting material for device fabrication.In chapter two, zero-dimensional Quantum Dots (QDs) are incorporated into electro
An investigation into the design of neural network controlled autonomous agents that navigate in uncertain environments using pre-existing visual landmarks.
Abstract in Chinese 從社會投資（social investment）的社會福利的角度來看，花蓮的發展，長期以來，著重在修復（repair）人口外移與老化的困境，而非預防（prevent）這個現象發生的原因。如果花蓮真的要強調永續發展，我覺得創新的思維應該要著重在預防，像是我們如何把人留下來？把好的產業留下來？〈花東地區發展條例〉裡提到人才東移的政策，花蓮縣綜合實施方案應該要更細部的討論這個部份，不是只有簡化成消費原住民文化的觀光產業，再者，如果觀光或是鄉村旅遊是花蓮發展很重要的一環，我們的教育準備好了嗎？ 最後，在其他國家對鄉村發展大多採用低衝擊的開發（Low impact development）的今天，我們能不能勇敢的說，我們不需要靠空中纜車，也可以欣賞到美景，我們不需要賽車場，也可以找到觀光的出路呢？ 花蓮縣政府在九月十六日舉辦了花蓮縣綜合實施方案初稿的聽證會，
This thesis utilises qualitative methods to examine what drives / impedes corporate action on climate change in the Swedish electricity industry. Reasoning from new institutional theory, this thesis examines the role of institutional logics as a determinant of corporate actions. Institutional logics are shared cognitively institutionalised structures that are thought to limit individuals’ capacity
This study has focused on: (i) differences in how males and females use the genes in the genome, (ii) how sex chromosomes evolve and (iii) how the evolutionary rate of genes are affected by the chromosome on which they are located on and the gene expression level they experience. A large-scale microarray was developed for the zebra finch, Taeniopygia guttata and techniques were developed so that t
This contribution traces the international contacts and impact of the leader school for German doctors ('Führerschule der deutschen Arzteschaft') in Alt Rehse 1935-1943 through studies of a visitors' book and of biographies.We suggest that the 'Föhrerschule', an institution providing political and ideological education for health professionals, interested non-German physicians to a larger extent t
Reporting criminal victimization to the police is no obvious act. The decision to file a complaint varies depending on the specific situation. This article discusses some young Swedish men’s narratives about contacting the police when mugged or assaulted. Although all of them have contacted the police it has not been self-obvious. Rather, they present reasons for not filing a complaint. However, a
One factor which can be expected to influence performance in applications where the user is expected to point a device in some direction to obtain information is the angle interval in which the user gets feedback. The present study was performed in order to get a better understanding of the influence of this angle interval on navigation performance. Results indicate that users are able to handle q
A discussion of motivations for doing archaeology. In the present there is a conflict between three different perspectives: Enlightment, teraphy and morale. The three perspectives go back to the Antique philosophical concepts of the truth, the beauty and the good, correlating to epistemology, estetics and ethics.
Popular Abstract in Swedish Hur kan man skapa en tredimensionell modell av ett objekt eller en plats från tvådimensionella bilder? Det är den centrala frågan i den här avhandlingen och en viktig fråga i datorseende generellt. Normalt delar man upp problemet i en serie basproblem. Ett basproblem kan till exempel vara att skatta kamerans rörelse mellan två bilder eller kamerapositionen för en ny bilThis thesis is concerned with the geometrical parts of computer vision, or more precisely, with the three-dimensional geometry. The overall aim is to extract geometric information from a set of images. Most methods for estimating the geometry of multiple views rely on the existence of robust solvers for a set of basic problems. Such a basic problem can be estimating the relative orientation of two
