  1. 1. Trade-off between starvation and predation : Weight-watching in Yellowhammers

    Author : Ineke T. van der Veen; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; populationsbiologi; Population Biology;

    Abstract : In this thesis I show that captive yellowhammers (Emberiza citrinella) strategically adjusted their level of body mass and diurnal trajectory of mass increase to experimentally increased predation risk. During winter, small birds need large fat reserves to survive the night. Therefore, they build up fat reserves every day. READ MORE

  2. 2. Commuting time choice and the value of travel time

    Author : Jan-Erik Swärdh; Lars Hultkrantz; Bruno De Borger; Örebro universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Value of time; Value of travel time; Commuting; Commuting time changes; Value of commuting time; Register data; On-the-job search; Revealed preferences; Stated preferences; Hypothetical bias; Scheduling constraints; Relocations; Certainty calibration; Quantile regression; Mixed logit; Gender differences; Economics; Nationalekonomi; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Economics; Nationalekonomi;

    Abstract : In the modern industrialized society, a long commuting time is becoming more and more common. However, commuting results in a number of different costs, for example, external costs such as congestion and pollution as well as internal costs such as individual time consumption. READ MORE

  3. 3. Growth versus the Environment - Is There a Trade-off?

    Author : Per Kågeson; Miljö- och energisystem; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; emissions reduction; material intensity; pollution control; sustainable development; resource depletion; environment; economic growth; energy; Environmental technology; Miljöteknik; kontroll av utsläpp;

    Abstract : This book shows that the intensity of use of energy and materials in OECD countries is diminishing over time despite falling metal and energy prices. Material demand is sometimes falling in absolute terms, but there are also a few examples of rapid growth. READ MORE

  4. 4. Real-Time Workload Models : Expressiveness vs. Analysis Efficiency

    Author : Martin Stigge; Wang Yi; Sanjoy Baruah; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Real-time systems; task models; EDF; fixed-priority scheduling; schedulability analysis; response-time analysis; abstraction refinement; Datavetenskap med inriktning mot realtidssystem; Computer Science with specialization in Real Time Systems;

    Abstract : The requirements for real-time systems in safety-critical applications typically contain strict timing constraints. The design of such a system must be subject to extensive validation to guarantee that critical timing constraints will never be violated while the system operates. READ MORE

  5. 5. Evolution of Plants : a mathematical perspective

    Author : Magnus Lindh; Åke Brännström; Jacob Johansson; Mats G Larson; Lennart Persson; Claus Rüffler; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Evolution; plants; mathematics; optimization; optimal control; adaptive dynamics; flowering; seasons; tree crown; drought; taproot; trade-off; strategy; trait; ESS; NPP; LAI; Red Queen; Mathematics; matematik;

    Abstract : The Earth harbors around 300 000 plant species. The rich and complex environment provided by plants is considered a key factor for the extraordinary diversity of the terrestrial fauna by, for example, providing food and shelter. READ MORE
