  2. 16. A Theoretical Study of Carbon Nanotubes in Electronic Packaging Applications

    Author : Zhili Hu; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; simulation; thermal interface material; continuum; electronic packaging; MDs; CNT;

    Abstract : The continuous decrease in size of transistors has allowed more components to be integrated in a single unit area and brings a range of opportunities as well as problems to the electronic packaging industry. To meet these challenges, the introduction of Carbon Nanotubes (CNT), which display a series of extraordinary properties, have attracted great interest. READ MORE

  4. 17. Laboratory measurements of airborne emissions from car brakes for clean air

    Author : Guido Perricone; Ulf Olofsson; Fulvio Amato; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automotive brake; non-exhaust emissions; inertia brake dynamometer; airborne particles; PM10; PN; isokinetic sampling; Rebrake; volatiles; real driving cycle; car brake emission factors; running-in.; Bilbroms; icke-avgasemissioner; skivbromsdynamometer; luftburna partiklar; PM10; PN; isokinetisk provtagning; Rebrake; volatiler; verkliga körcykler; emissionsfaktorer; in-körning.; Machine Design; Maskinkonstruktion;

    Abstract : Brake systems are used to safely stop vehicles. The brake pads are pressed against the brake disc, transforming the kinetic energy of the vehicle into heat to be dissipated. READ MORE

  5. 18. Analysis of the Thermal Indoor Climate with Computational Fluid Dynamics for Buildings in Sub-arctic Regions

    Author : Daniel Risberg; Lars Westerlund; Patrik Rhodin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Abstract : This thesis aims to increase the knowledge of simulation of thermal indoor climate for nearly zero energy buildings in a sub-arctic climate. Air heating systems in cold climate generate temperature gradients, which negatively affects the thermal indoor climate. Stand-ard multi-zone modeling has problemswithpredicting these gradients.

  6. 19. Measuring and Predicting Transient Diesel Engine Emissions

    Author : Anders Westlund; Hans-Erik Ångström; Rolf Egnell; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emission modelling; Mechanical and thermal engineering; Mekanisk och termisk energiteknik;

    Abstract :   Due to its impact on human health and the nature surrounding us, diesel engine emissions have been significantly reduced over the last two decades. This reduction has been enforced by the legislating organs around the world that gradually have made the manufacturers transform their engines to today’s complex high-tech products. READ MORE

  7. 20. Testing and Modelling of Electrical Traction Machines : Performance Characterisation with Measurements from Transient Operation

    Author : Sebastian Hall; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical machines; Interior permanent magnet synchronous machines IPMSMs ; characterisation; Testing; Modelling; Electrical machines; Interior permanent magnet synchronous machines IPMSMs ; Testing; Characterisation; Modelling;

    Abstract : This thesis presents methods to derive and model the performance characteristics of interior permanent magnet machines – a machine type which is commonly used for propulsion of electrical vehicles. The thesis divides the performance characteristics into three subcategories: The electromagnetic properties, the loss profile and the thermal behaviour of the machines. READ MORE
