  2. 1. Planning production and supply chain in energy intensive process industries

    Author : Martin Waldemarsson; Helene Lidestam; Martin Rudberg; Magnus Karlsson; Sophie D'Amours; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process industry; Energy-intensive production processes; Energy system; Energy management; Production planning; Supply chain planning; Case studies; Mixed Integer Linear Programming; Modelling; Specialty chemicals; Pulp; Steel;

    Abstract : To make a difference among the energy intensive process industries, this dissertation addresses production planning and supply chain planning problems related to industrial energy management issues. The energy issue is turning more and more important from different angles, involving price as well as environmental problems due to climate change leading to political pressure on all energy users.

  4. 2. A Study of Parton Dynamics from Deep Inelastic Scattering Events Containing a Jet in the Forward Direction

    Author : Martin Karlsson; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum field theory; Elementary particle physics; DIS; ep scattering; H1; jets; forward jet; small-x; parton dynamics; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2002:Karlsson;

    Abstract : The DIS ep-scattering parton dynamics at low-x is characterised by an initial state cascade in which the virtualities of the propagator gluons are expected to take any kinematically allowed value, in contrast to the leading log behaviour. These dynamics might be enhanced by selecting events in which an energetic jet is found in the forward angular region at HERA, 1. READ MORE

  5. 3. Methods to Generate Size- and Composition Controlled Aerosol Nanoparticles

    Author : Martin Karlsson; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; differential mobility analyzer DMA ; transfer function; binary alloy nanoparticles; nanoparticle generator; thermal decomposition; Physics; sintering; Fysik; size selection; nanoparticles; aerosol technology; Fysicumarkivet A:2004:Karlsson;

    Abstract : This thesis describes experiments performed using different methods to produce aerosol nanoparticles with control over size and composition. The process included differential mobility analyzers (DMAs) as size-selecting instruments and tube furnaces for particle synthesis. READ MORE

  6. 4. Cache memory design trade-offs for current and emerging workloads

    Author : Martin Karlsson; Erik Hagersten; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Systems; Datorteknik;

    Abstract : The memory system is the key to performance in contemporary computer systems. When designing a new memory system, architectural decisions are often arbitrated based on their expected performance effect. It is therefore very important to make performance estimates based on workloads that accurately reflect the future use of the system. READ MORE

  7. 5. Electro-mechanical modelling and analysis of hydroelectric rotor systems

    Author : Martin Karlsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Aided Design; Datorstödd maskinkonstruktion;

    Abstract : Hydroelectric power generation supplies about 20 percent of the world's electricity and is the most important renewable energy converting industry. The installed capacity of Hydro-electrical power generation is approximately 700GW with a production of 2600TWh/year. The technically feasible potential of hydro power is 14000TWh/year. READ MORE
