  4. 2. Detection and Tracking in Thermal Infrared Imagery

    Author : Amanda Berg; Michael Felsberg; Jörgen Ahlberg; Thomas B. Moeslund; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermal; infrared; detection; tracking;

    Abstract : Thermal cameras have historically been of interest mainly for military applications. Increasing image quality and resolution combined with decreasing price and size during recent years have, however, opened up new application areas. They are now widely used for civilian applications, e.g. READ MORE

  5. 3. Development of a regeneration procedure for commercial automotive three-wy catalysts

    Author : Henrik Birgersson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; deactivation; fouling; sintering; poisoning; palladium; rhodium; regeneration; dispersion; thermal gas treatment; oxy-chlorine; TWC; automotive catalyst; Chemical process equipment; Kemisk apparatteknik;

    Abstract : Car exhaust catalysts were introduced in the early 1980’s, to limit the release of pollutants such as hydrocarbons, carbon monoxides and nitrogen oxides. These catalysts contain noble metals such as palladium (Pd), platinum (Pt) and rhodium (Rh) and are able to simultaneously abate all three of the above-mentioned pollutants, hence the name three-way catalyst (TWC).

  6. 4. Analysis of PEM Fuel Cell Stacks and Systems with Water/Thermal Balances

    Author : Takamasa Ito; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; PEM Fuel Cell Systems ; Water Thermal Balances ; Heat Exchangers ; PEM Fuel Cell Stacks ;

    Abstract : The Proton Exchange Membrane (PEM) fuel cell has been investigated for a long time, and is regarded as a new energy source for various applications, such as portable, stationary and automotive ones. However, due to the shortage of the infrastructure in the society, the high cost, the difficulty of the water/thermal management, etc. READ MORE

  7. 5. Aerodynamic Design and Installation Effects of Automotive Electric Cooling Fans

    Author : Debarshee Ghosh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blade Element Momentum BEM ; low-pressure axial fans; electric cooling fans; automotive thermal management; CFD simulations; upstream blockage; fans in parallel;

    Abstract : Electric cooling fans play a crucial role in automotive thermal management. They generate the airflow required for heat rejection from the expended coolant circulating within the heat exchanger. This thesis focuses on the aerodynamic design and installation effects of electric cooling fans or "E-fans". READ MORE
