  1. 21. Modelling trade-offs between forest bioenergy and biodiversity

    Author : Xi Pang; Ulla Mörtberg; Karin Öhman; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : Globally, biodiversity is declining due to loss, fragmentation and degradation of habitat, which undermines ecosystem functioning and therefore threatens also the ability of ecosystems to supply ecosystem services. Moreover, there is a need for adapting to climate change as well as securing the supply of energy, which have led to a shift in energy consumption from fossil fuel to renewables, especially biomass, which in turn put increasing pressure on ecosystems and biodiversity.

  2. 22. Population dynamics and demography - inferences from stochastic models

    Author : Jonas Knape; Biologiska institutionen; []

    Abstract : Time series analysis of population abundances is a common approach to making inferences about population dynamics, and especially for estimating density dependence. Traditionally the impact of potential errors in observations or measurements of the abundances on inference has been ignored. READ MORE

  3. 23. Decision Models for the Procurement of Subsidised Air Services

    Author : Alan Kinene; Tobias Andersson Granberg; Valentin Polishchuk; Clas Rydergren; Svein Bråthen; Linköpings universitet; []

    Abstract : Small communities or remote regions are usually ignored by airlines because they have insufficient passenger demand and the air services to and from these regions are unprofitable. Free market conditions would lead to the lack of air connectivity to and from remote regions, hence transportation authorities intervene by procuring air services to guarantee improved accessibility for these regions.

  4. 24. Stock data, trade durations, and limit order book information

    Author : Ola Simonsen; Kurt Brännäs; Johan Knif; Umeå universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Finance; Maximum likelihood; Estimation; ACD; News; Multivariate; Intraday; Market; Economics; Nationalekonomi;

    Abstract : This thesis comprises four papers concerning trade durations and limit order book information. Paper [1], [2] and [4] study trader durations, e.g., the time between stock transactions in intra-day data. READ MORE

  5. 25. Model Checking of Software Systems under Weak Memory Models

    Author : Tuan-Phong Ngo; Mohamed Faouzi Atig; Parosh Aziz Abdulla; Philipp Rümmer; Viktor Vafeiadis; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model checking; Concurrent program; Weak memory model; Computer Science; Datavetenskap;

    Abstract : When a program is compiled and run on a modern architecture, different optimizations may be applied to gain in efficiency. In particular, the access operations (e.g., read and write) to the shared memory may be performed in an out-of-order manner, i. READ MORE
