  2. 11. Towards High Efficiency Powertrains

    Author : Jayesh Khatri; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid powertrain; water injection; Downsized spark-ignition engines; RON; efficient engine starts; knock mitigation; warm engine starts;

    Abstract : In recent years there has been a great shift whereby conventional vehicles powered by an internal combustion (IC) engine are being partially or completely replaced by electrified alternatives; almost all major automotive manufacturers have made statements indicating a shift towards electrification. This shift has been driven in large part by concerns about climate change, which have prompted lawmakers to introduce increasingly strict regulations limiting vehicular emissions, particularly of carbon dioxide (CO2).

  4. 12. Penetrablity for cementitious injection groups

    Author : Daniel Eklund; KTH; []
    Keywords : ;

    Abstract : Grouting as a method of strengthening and sealing rock, soiland concrete is widely spread. The possibilities of sealingstructures are of great importance in both economical andenvironmental point of view. The costs of grouting have incertain projects been as high as the cost for the blasting andexcavation of the tunnel. READ MORE

  5. 13. Structural Studies of Large dsDNA Viruses using Single Particle Methods

    Author : Hemanth Kumar Narayana Reddy; Martin Svenda; Sarah Butcher; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PR772; phage; PRD1; Bacteriophage; coliphage; Melbournevirus; Cedratvirus; lurbo; Pithovirus; CryoEM; Single particle imaging; Coherent; Diffractive; Imaging; Soft X-ray; Microscopy; Microscope; GDVN; High resolution; XFEL; aerosol; Injection; electrospray; gas dynamic virtual nozzle; CDI; CXI; FEL; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

    Abstract : Structural studies of large biological assemblies pose a unique problem due to their size, complexity and heterogeneity. Conventional methods like x-ray crystallography, NMR, etc. are limited in their ability to address these issues. To overcome some of these limitations, single particle methods were used. READ MORE

  6. 14. Management of technology in the process industries:  Matching market and machine

    Author : Peter Samuelsson; Pär Jönsson; Rob Boom; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process industries; manufacturing; innovation; configuration; strategizing; capability; configuration modelling; process industries; production system; physical modelling; AOD; converter geometry; injection; mixing times; electric arc furnace; EAF; post-combustion; high-impedance; network disturbances; operational results; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : The process industries span multiple industrial sectors and constitute a substantial part of the entire manufacturing industry. Since companies belonging to this family of industries are often very asset intensive, their ability to respond to changes is often limited in the short term. READ MORE

  7. 15. REACTIVE TRANSPORT MODELLING OF DISSOLVED CO2 IN POROUS MEDIA : Injection into and leakage from geological reservoirs

    Author : Nawaz Ahmad; Anders Wörman; Auli Niemi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 geological storage and safety; leakage of brine saturated with dissolved CO2; reactive transport; fracture; advection; dispersion and diffusion; sorption; carbonate minerals kinetic reactions; calcite; dolomite; siderite; porosity; permeability; heat transport; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : The geological sequestration of carbon dioxide (CO2) is one of the options of controlling the greenhouse gas emissions. However, leakage of CO2 from the storage reservoir is a risk associated with geological sequestration. Over longer times, large-scale groundwater motion may cause leakage of dissolved CO2 (CO2aq).
