1. 1. Jet Production and Parton Dynamics in Deep Inelastic Scattering

   Författare :Mattias Davidsson; Partikel- och kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum field theory; Elementary particle physics; DIS; ep scattering; HERA; H1; jets; small-x; Parton Dynamics; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2001:Davidsson;

   Sammanfattning : Hard QCD processes have been studied by measuring the di-jet event rate for deep inelastic scattering in the kinematic range 5 < Q2 < 100 GeV2 and 10-4 < x < 10-2. The jets we re reconstructed using the cone algorithm in the hadronic center-of-mass frame in which the transverse momentum of the jets were required to be greater than 5 GeV. LÄS MER

3. 2. Modeling human gut microbiota: from steady states to dynamic systems

   Författare :Hao Luo; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dynamics.; metabolic modeling; genome-scale metabolic model; gut microbiota; cybernetic model;

   Sammanfattning : Human gut microbes are an essential part of human sub-microscopic systems and involved in many critical biological processes such as Type 2 diabetes (T2D) and osteoporosis. However, the underlying mechanisms are unclear. LÄS MER

4. 3. Essays on Energy and Climate Policy – Green Certificates, Emissions Trading and Electricity Prices

   Författare :Anna Widerberg; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Attitudes; Carbon Dioxide; Carbon Intensity; Climate Change; Electricity; Electricity Prices; Emissions Trading; Emission Allowances; Environment; Fairness; GARCH models; Lyapunov Exponents; Market Structure; Personal Carbon Allowances; Public Opinion; Reconstructed Dynamics; Stability; Tradable Energy Quotas; Tradable Green Certificates; Volatility;

   Sammanfattning : Paper I: An Electricity Trading System with Tradable Green Certificates and CO₂-emission Allowances Combinations of various policy instruments to deal with the threat of climate change are used throughout the world. The aim of this article is to investigate an electricity market with two different policy instruments, Tradable Green Certificates (TGCs) and CO₂ emission allowances (an Emission Trading System, ETS).

5. 4. Data Assimilation in Fluid Dynamics using Adjoint Optimization

   Författare :Johan Lundvall; Vladimir Kozlov; Per Weinerfelt; Matts Karlsson; Anders Szepessy; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Data assimilation; Inverse problem; Adjoint optimization; Burgers equation; nonlinear; Landweber; Initial pressure; Euler flow; Applied mathematics; Tillämpad matematik;

   Sammanfattning : Data assimilation arises in a vast array of different topics: traditionally in meteorological and oceanographic modelling, wind tunnel or water tunnel experiments and recently from biomedical engineering. Data assimilation is a process for combine measured or observed data with a mathematical model, to obtain estimates of the expected data. LÄS MER

7. 5. Dynamics and Mechanisms of Adaptive Evolution in Bacteria

   Författare :Song Sun; Dan Andersson; Diarmaid Hughes; Josep Casadesús; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; adaptive evolution; mutation; genome rearrangements; antibiotic resistance; gene amplification; genome reduction; directed evolution; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

   Sammanfattning : Determining the properties of mutations is fundamental to understanding the mechanisms of adaptive evolution. The major goal of this thesis is to investigate the mechanisms of bacterial adaptation to new environments using experimental evolution. LÄS MER
