  2. 6. Transient Air to Fuel Ratio Response in a Fuel Injected S.I Engine

    Author : Göran Almkvist; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; dynamic; A F; model; transient; air to fuel; response; time constant; film; behavior; lambda; time-delay; fuel; mass; deposit factor;

    Abstract : Future emission standards make it necessary to focus on the conditions under which engine emissions are produced, especially before the catalyst light off. During practical driving conditions, such as those represented by the FTP 75 test cycle, the engine is operated very much under transient conditions regarding load and speed. READ MORE

  4. 7. First-Order Algorithms for Communication Efficient Distributed Learning

  6. 9. Continuous-Time Delta-Sigma Modulators for Wireless Communication

    Author : Mattias Andersson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; return-to-zero; A D converter; loop delay; delta-sigma; ADC; CMOS; STF; continuous-time; sigma; delta; filtering; CT; RZ;

    Abstract : The ever increasing data rates in wireless communication require analog to digital converters (ADCs) with greater requirements on speed and accuracy, while being power efficient to prolong battery life. This dissertation contains an introduction to the field and five papers that focus on the continuous-time (CT) Delta-Sigma modulator (DSM) as ADC. READ MORE
