  2. 6. Geometry in Varro, Cicero, and Vitruvius : A Philological Study

    Author : Erik Bohlin; University of Gothenburg Department of Languages and Literatures; []
    Keywords : HUMANIORA; HUMANITIES; Latin language; Latin; Latin; Latin;

    Abstract : In antiquity the mathematical field of geometry was developed by the Greeks. As theRomans came into closer contact with Greek culture, they also encountered its repertoire of learning, of which geometry was a part. READ MORE

  4. 7. Simplified models for emission formation in diesel engines during transient operation

    Author : Anders Westlund; Hans-Erik Ångström; Martti Larmi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel engine; emission modeling; transient operation; NOx; Soot; Mechanical energy engineering; Mekanisk energiteknik;

    Abstract : The work presented in this thesis is the result of the KTH CICERO project “Dynamic Engine Performance” in which the main objective was to develop simple models foremission formation. The demand for such models is increasing, mainly due to the tightening emission legislation for diesel engines which has lead to more complex engines and thereby more laborious development and calibration processes.

  5. 8. Studies of flow duct acoustics with applications to turbocharged engines

    Author : Hans Rämmal; Hans Boden; Mats Åbom; Antonio Torregrosa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IC-engine; turbocharger; duct termination; flow duct; exhaust system; inlet system; acoustic source; one-port; two-port; source model; transmission loss; two-port matrix; reflection coefficient; source strength; multi-load method; Acoustics; Akustik;

    Abstract : A number of experimental and theoretical studies, performed in the field of technical flow duct acoustics are presented in this thesis. The acoustical methods treated are implemented on turbocharged IC-engines and engine gas exchange system components. A new method based on the well-known two-load technique has been developed.
