  2. 1. Cost-optimality approach for prioritisation of buildings envelope energy renovation : A techno-economic perspective

    Author : Farshid Bonakdar; Angela Sasic Kalagasidis; Keith Jones; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building renovation; Energy efficiency; Cost-optimality; costeffectiveness; Building envelope; Residential buildings; Building energy simulation; Brute-force algorithm; Sustainable Built Environment; Hållbar byggd miljö;

    Abstract : The existing residential buildings in the European countries are rather old and often fail to meet the current energy performance criteria. In Sweden, about 45% of the existing residential buildings have been constructed before 1960. READ MORE

  4. 2. Carbon Dioxide and Water Vapour Exchange within a Norway Spruce Canopy

    Author : Lasse Tarvainen; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nitrogen allocation; optimality; stomatal conductance; photosynthesis; resource use efficiency; stem respiration; conifer;

    Abstract : Terrestrial ecosystems can act both as sinks and sources in the global carbon cycle. Forests are an important part of this system and a good understanding of their carbon balance is essential for assessments of the future climate and for evaluating mitigation strategies. READ MORE

  5. 3. Calibration, Optimality and Financial Mathematics

  7. 5. Multivariate Aspects of Phylogenetic Comparative Methods

    Author : Krzysztof Bartoszek; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; General Linear Model; Ornstein-Uhlenbeck process; Multivariate phylogenetic comparative method; Evolutionary model; Adaptation; Optimality; Measurement error; Regression; Adaptation; Major-axis regression; Reduced major-axis regression; Structural equation; Allometry; Phylogenetic inertia; Allometry;

    Abstract : his thesis concerns multivariate phylogenetic comparative methods. We investigate two aspects of them. The first is the bias caused by measurement error in regression studies of comparative data. We calculate the formula for the bias and show how to correct for it. READ MORE
