2. 1. Green Buildings : Exploring performance and thresholds

   Author : Magnus Bonde; Svante Mandell; Partick McAllister; KTH; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Green Buildings; Energy-Efficient Buildings; EPC; Indoor Environment Quality IEQ ; Real Options Analyses ROA ; Real-Estate Economics; Real Estate and Construction Management; Fastigheter och byggande;

   Abstract : The overall aim of this research project is to study green/energy-efficient real estate from an economic perspective. The thesis summarizes the results from five different studies with a connection to green/energy-efficient real estate. READ MORE

4. 2. Electrochromic Nickel – Tungsten Oxides : Optical, Electrochemical and Structural Characterization of Sputter-deposited Thin Films in the Whole Composition Range

   Author : Sara Green; Gunnar Niklasson; Claes-Göran Granqvist; Esteban Avendaño; Aline Rougier; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrochromism; Nickel oxide; Tungsten oxide; Lithium intercalation; Sputtering; Thin films; Nanostructures; Optical properties; Solid State Physics; Fasta tillståndets fysik;

   Abstract : This thesis investigates the electrochromic NixW1-x oxide thin film system, where 0 < x < 1. The thin films were deposited by reactive DC magnetron co-sputtering from one Ni and one W metal target. In addition, Ni oxide was deposited with water vapor added to the sputtering gas. READ MORE

5. 3. Towards Green Wireless Access Networks : Main Tradeoffs, Deployment Strategies and Measurement Methodologies

   Author : Sibel Tombaz; Jens Zander; Ki Won Sung; Ben Slimane; Peter Legg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; wireless access; green radio; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : Wireless access networks today consume 0.5 percent of the global energy. Rapidly growing demand for capacity will further increase the energy consumption. Thus, improving energy efficiency has a great importance not only for environmental awareness but also to lower the operational cost of network operators. READ MORE

6. 4. Cooperative Communications : Link Reliability and Power Efficiency

   Author : Tafzeel ur Rehman Ahsin; Ben Slimane; Xavier Lagrange; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative Communications; Link Reliability; Power Efficiency; Energy Efficiency; Network Coding; Cooperative Relaying; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : Demand for high data rates is increasing rapidly for the future wireless generations, due to the requirement ofubiquitous coverage for wireless broadband services. More base stations are needed to deliver these services, in order tocope with the increased capacity demand and inherent unreliable nature of wireless medium. READ MORE

7. 5. Hydrological and sediment yield modelling in Lake Tana Basin, Blue Nile Ethiopia

   Author : Shimelis Gebriye Setegn; Bijan Dargahi; Anders Wörman; C. Green Rossi; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SWAT; Lake Tana; Blue Nile; hydrological modelling; watershed modelling; MCE; SUFI-2; GLUE; ParaSol; streamflows; sediment yield; erosion; water balance; model calibration; Hydrology; Hydrologi;

   Abstract : Land and water resources degradation are the major problems on the Ethiopian highlands. Poor land use practices and improper management systems have played a significant role in causing high soil erosion rates, sediment transport and loss of agricultural nutrients. So far limited meas-ures have been taken to combat the problems. READ MORE
