  1. 1. Identification of Stochastic Nonlinear Dynamical Models Using Estimating Functions

    University dissertation from KTH Royal Institute of Technology

    Author : Mohamed Abdalmoaty; Håkan Hjalmarsson; Adrian Wills; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prediction Error Method; Maximum Likelihood; Data-driven; Learning; Stochastic; Nonlinear; Dynamical Models; Non-stationary Linear Predictors; Intractable Likelihood; Latent Variable Models; Estimation; Process Disturbance; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Data-driven modeling of stochastic nonlinear systems is recognized as a very challenging problem, even when reduced to a parameter estimation problem. A main difficulty is the intractability of the likelihood function, which renders favored estimation methods, such as the maximum likelihood method, analytically intractable. READ MORE

  2. 2. Asymmetric transfer hydrogenation of ketones Catalyst development and mechanistic investigation

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Katrin Ahlford; Hans Adolfsson; Martin Wills; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Asymmetric catalysis; reduction; amino acid; rhodium; mechanistic investigation; kinetic study; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi; Organic Chemistry; organisk kemi;

    Abstract : The development of ligands derived from natural amino acids for asymmetric transfer hydrogenation (ATH) of prochiral ketones is described herein. In the first part, reductions performed in alcoholic media are examined, where it is found that amino acid-derived hydroxamic acids and thioamides, respectively, are simple and versatile ligands that in combination with [RhCp*Cl2]2 efficiently catalyze this particular transformation.

  3. 3. Theoretical Descriptions of Complex Magnetism in Transition Metals and Their Alloys

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Marcus Ekholm; Igor Abrikosov; Sergey Simak; Leonid Pourovskii; John M. Wills; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis, various methods for studying solids by simulations of quantummechanical equations, have been applied to transition metals and their alloys. Transition metals such as Fe, Ni, and Mn, are not only cornerstones in modern technology, but also key components in the very fabric of the Earth interior. READ MORE

  4. 4. Economic Decisions and Social Norms in Life and Death Situations

    University dissertation from Uppsala : Nationalekonomiska institutionen, Uppsala universitet

    Author : Oscar Erixson; Henry Ohlsson; Mikael Elinder; Matthew Lindqvist; [2013]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mortality; social norms; dicrimination; maritime disasters; altruism; estate division; wills; equal sharing; bequests motives; inheritances; windfall gains; tax reform; labor income; capital income; health; Economics; Nationalekonomi;

    Abstract : Essay 1: (with Mikael Elinder) Since the sinking of the Titanic, there has been a widespread belief that the social norm of “women and children first” (WCF) gives women a survival advantage over men in maritime disasters, and that captains and crew members give priority to passengers. We analyze a database of 18 maritime disasters spanning three centuries, covering the fate of over 15,000 individuals of more than 30 nationalities. READ MORE

  5. 5. Becoming Biofuels. The messy assembling of resources, sustainability, poverty, land use, and nation-states

    University dissertation from Uppsala : Nationalekonomiska institutionen, Uppsala universitet

    Author : Marie Widengård; Göteborgs universitet.; Gothenburg University.; [2015]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; biofuels; jatropha; assemblages; governmentality; political ecology; political economy; ethnography; governance; materiality; authority; territory; sovereignty; resources; poverty; sustainability; land use change; states; standards; certification; Africa; Zambia; Mozambique; Tanzania; Kenya; Brazil; EU;

    Abstract : Biofuels have come to represent the will to mitigate climate change by replacing fossil fuels with so-called climate-friendly and renewable plant sources, and to improve rural and poor conditions in the South through biofuel crop production, farm job creation, and smallholder cash cropping. The expansion of biofuels in countries in the South largely pivoted upon ‘the will to develop’, specifically through the oil shrub Jatropha curcas L. READ MORE
