1. 6. An analysis of architectural and urban planning strategies for developing energy efficient cities in China

   Författare :Zhenhong Gu; Fredrik Gröndahl; Dong Wei; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Energy efficiency; Nanjing; China; urban planning; passive house; low exergy system; Building Environmental Assessment; LCA; Swedish housing; Hammarby Sjöstad; eco-village; game theory; systems theory; soft systems methodology; Industrial Ecology; Industriell ekologi;

   Sammanfattning : This thesis presents a detailed analysis of architecture and urban planning strategies for developingenergy-efficient cities in a Chinese context. The overall aim of the work is to examine how Chineseurbanisation and city construction can be improved from an energy-saving perspective. LÄS MER

3. 7. Hydropower plants and power systems : Dynamic processes and control for stable and efficient operation

   Författare :Weijia Yang; Per Norrlund; Urban Lundin; Christophe Nicolet; Uppsala universitet; []
   Nyckelord :;

   Sammanfattning : As the largest global renewable source, hydropower shoulders a large portion of the regulation duty in many power systems. New challenges are emerging from variable renewable energy (VRE) sources, the increasing scale and complexity of hydropower plants (HPPs) and power grid. LÄS MER

4. 8. Environmental Integration in Sustainable Urban Planning from an Institutional Perspective : A Study of Swedish and Chinese Eco-City Development

   Författare :Ying Yin; Maria Håkansson; Amy Rader Olsson; Per G. Berg; KTH; []
   Nyckelord :Environmental Integration; Sustainable Urban Planning; Institutional Condition; Eco-Cities; Sweden; China; Planering och beslutsanalys; Planning and Decision Analysis;

   Sammanfattning : The continuously rising attention to and practice of eco-city development in Sweden and China, as well as the countries’ active cooperation has motivated this study and the exploration of eco-city development in these two countries. In eco-city development, diverse environmental issues may well be beyond the planning sector’s capacity and need to be resolved elsewhere by other authorities and agencies in such areas as energy, water and traffic.

5. 9. Multitemporal Remote Sensing for Urban Mapping using KTH-SEG and KTH-Pavia Urban Extractor

   Författare :Alexander Jacob; Yifang Ban; Paolo Gamba; Francesca Bovolo; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; KTH-SEG; ASAR; HJ-1B; Urban Land Cover Mapping; OBIA; Segmentation; Image Classification; KTH-Pavia Urban Extractor; Urban Extent; Geodesy and Geoinformatics; Geodesi och geoinformatik;

   Sammanfattning : The objective of this licentiate thesis is to develop novel algorithms and improve existing methods for urban land cover mapping and urban extent extraction using multi-temporal remote sensing imagery. Past studies have demonstrated that synthetic aperture radar (SAR) have very good properties for the analysis of urban areas, the synergy of SAR and optical data is advantageous for various applications.

7. 10. Urban Change Detection Using Multitemporal SAR Images

   Författare :Osama Yousif; Yifang Ban; Lorenzo Bruzzone; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Change detection; High resolution; Image denoising; Kittler-Illingworth; MAP-MRF; Multitemporal SAR images; Nonlocal means; Object-based; Otsu; Outlier detection; Remote sensing; SAR speckle; Urban; Geodesy and Geoinformatics; Geodesi och geoinformatik;

   Sammanfattning : Multitemporal SAR images have been increasingly used for the detection of different types of environmental changes. The detection of urban changes using SAR images is complicated due to the complex mixture of the urban environment and the special characteristics of SAR images, for example, the existence of speckle.
