  1. 1. Energy analysis for sustainable mega-cities

    Author : Aumnad Phdungsilp; Björn Palm; Ivo Martinac; Charles Heaps; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asian mega-cities; energy demand; metabolism of cities; energy modeling; sustainable energy; energy planning; multi-criteria decision-making; Mechanical energy engineering; Mekanisk energiteknik;

    Abstract : ABSTRACT Cities throughout Asia have experienced unprecedented economic development over the past decades. In many cases this has contributed to their rapid and uncontrolled growth, which has resulted in a multiplicity of problems, including rapid population increase, enhanced environmental pollution, collapsing traffic systems, dysfunctional waste management, and rapid increases in the consumption of energy, water and other resources.

  2. 2. Nesting ecology of the grass snake (Natrix natrix) and its implications for conservation

    Author : Kristin Löwenborg Di Marino; Mattias Hagman; Sören Nylin; Tobias Uller; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; agriculture; anthropogenic; climate; embryonic development; incubation; zoologisk ekologi; Animal Ecology;

    Abstract : The onset of agriculture about 12,000 years ago has had a major influence on the biodiversity of plants and animals. Unfortunately, the rapid changes in agricultural practices that has occurred in recent times has negatively affected many farmland species. READ MORE

  3. 3. Dynamic algorithms: new worst-case and instance-optimal bounds via new connections

    Author : Thatchaphol Saranurak; Danupon Nanongkai; Piotr Sankowski; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datalogi;

    Abstract : This thesis studies a series of questions about dynamic algorithms which are algorithms for quickly maintaining some information of an input data undergoing a sequence of updates. The first question asks \emph{how small the update time for handling each update can be} for each dynamic problem. READ MORE

  4. 4. Stump as a fuel : the influence of harvesting technique and storage method on fuel quality of Norway spruce

    Author : Erik Anerud; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Uncertain long-term availability of fossil fuels and the negative environmental impact of using it have created an urgent need for reliable renewable energy sources. Wood fuel, particularly forest residues is one of these sources which are in high demand in Sweden today. READ MORE

  5. 5. A model of pH and redox buffer depletion in waste landfills

    Author : James Crawford; KTH; []
    Keywords : ;

    Abstract : The geochemical processes governing the release of heavymetal contaminants from solid waste materials have been studiedexperimentally and modelled using a mass balance approach. Theaim of the modelling work was to develop calculation tools thatcan be used to predict the release rate of heavy metals fromwaste heaps or landfills. READ MORE
