1. 36. Initial Oxidation of β-NiAl(Pt) Coatings and Model Alloys

   Författare :Henrik Svensson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FIB-SEM; SEM; #946; TEM; Diffusion Coatings; Metal-Oxide Interface; High Temperature Oxidation; Cavities; Platinum; -NiAl;

   Sammanfattning : The aim of this work was to investigate the oxidation properties of NiAl coatings and model materials during high temperature oxidation. One of the important issues was to elucidate the beneficial role of Pt additions. A better understanding of the involved processes provides a key for the further improvement of the coatings performance. LÄS MER

3. 37. A novel approach to text classification

   Författare :Niklas Zechner; Johanna Björklund; Efstathios Stamatatos; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Text classification; natural language processing; automata; Computer Science; datalogi;

   Sammanfattning : This thesis explores the foundations of text classification, using both empirical and deductive methods, with a focus on author identification and syntactic methods. We strive for a thorough theoretical understanding of what affects the effectiveness of classification in general. LÄS MER

4. 38. Lighting simulation for a more value-driven building design process

   Författare :Anahita Davoodi; Thorbjörn Laike; Peter Johansson; Annika Moscati; Jönköping University; []
   Nyckelord :lighting simulation; lighting design; lighting quality; energy efficiency; perception;

   Sammanfattning : Concerns about global warming are increasing, hence, the urgency to cut carbon emissions. Reducing energy consumption, including lighting energy, is seen as the primary solution. Yet, solving the environmental factor should not come at the cost of other pillars of sustainable development. LÄS MER

5. 39. Dosimetry in brachytherapy : application of the Monte Carlo method to single source dosimetry and use of correlated sampling for accelerated dose calculations

   Författare :Håkan Hedtjärn; David Rogers; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Three issues related to brachytherapy dosimetry are addressed in this thesis. (1) The prospect of using Compton scattering to measure energy spectra from a high dose-rate (HDR) 192Ir source is discussed and a Compton spectrometer evaluated. LÄS MER

7. 40. Understanding the Roles of Stakeholders in the Water and Sanitation Sector- Implementation and Operation of Water Supply and Sanitation Systems in the Kanata metropolitan region, Bolivia

   Författare :Ida Helgegren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Community management; SDG 6; Transition; Wastewater; Urban areas; Adoption; Universal access; Service providers; Socio-technical regimes; Households;

   Sammanfattning : This thesis aims to understand how distinct population segments access safe water and sanitation services, including the role of CBOs and individual households. A qualitative case study approach of the water and sanitation sector of the Kanata metropolitan region, Bolivia was selected. LÄS MER
