  1. 1. The physiology of cross-country skiing : With special emphasis on the role of the upper body

    University dissertation from Karolinska institutet

    Author : HC Holmberg; Björn Ekblom; Johnny Nilsson; Niels H. Secher; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin Teknik; Medicine Technology;

    Abstract : Cross-country skiing has been of great interest for exercise physiologists during the last century and is regarded as one of the most demanding endurance sports. Of special interest is that the athletes have extraordinary high aerobic power and that both upper and lower body muscles are involved to various degrees in the different skiing techniques.

  3. 3. Cryptanalysis of Selected Stream Ciphers

    University dissertation from Department of Electrical and Information Technology, Lund University

    Author : Paul Stankovski; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stream cipher; cryptanalysis; FCSR; state recovery; linear relations; optimal sampling; distinguisher; HC; nonrandomness; greedy bit set algorithm.;

    Abstract : The aim of this dissertation is to show some cryptanalytical results on a selection of stream ciphers. We have grouped theory and results into three main parts. The first part focuses on the FCSR-based constructions X-FCSR and F-FCSR-H v3. For the X-FCSR family of stream ciphers we perform a severe state recovery attack. READ MORE

  4. 4. Experimental and kinetic studies of H2 effect on lean exhaust aftertreatment processes: HC-SCR and DOC

    University dissertation from Department of Electrical and Information Technology, Lund University

    Author : Muhammad Mufti Azis; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HC-SCR; NO oxidation.; Hydrogen effect; NOx reduction; Kinetic modeling; Silver Alumina; DOC; Platinum Alumina;

    Abstract : With a growing concern to lower greenhouse gas emissions from road transportation, lean burn and diesel engines will keep playing an important role in the future. Development of a highly efficient and durable process to reduce NOx to N2 becomes a challenging issue especially in the presence of ample O2 concentration as in lean burn exhaust. READ MORE

  5. 5. Studies of hydrocarbon-assisted selective catalytic reduction of nitrogen oxides - DME as reductant and reaction mechanism over silver/alumina

    University dissertation from Department of Electrical and Information Technology, Lund University

    Author : Stefanie Tamm; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ZSM-5; NCO; HC-SCR; Dimethyl ether; reaction mechanism; silver alumina;

    Abstract : Increasing amounts of carbon dioxide are attaining worldwide growing attention as one probable cause for global warming. Together with the expected peak in oil production and an increasing oil demand, this results in a greater interest in more fuel effective lean burn engines (i.e. operation with excess oxygen).
