  1. 1. Celestial Cycles : Astronomical Concepts of Regeneration in the Ancient Egyptian Coffin Texts

    University dissertation from Uppsala : Institutionen för arkeologi och antik historia

    Author : Patrik Wallin; Mittuniversitetet.; Uppsala universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; SOCIAL SCIENCES Statistics; computer and systems science Informatics; computer and systems science; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Informatik; data- och systemvetenskap; HUMANITIES and RELIGION History and philosophy subjects Archaeology subjects; HUMANIORA och RELIGIONSVETENSKAP Historisk-filosofiska ämnen Arkeologiämnen; Egyptology; Egyptologi; Archaeology; Ancient Egypt; Coffin Texts; Astronomy; Middle Kingdom; calendars; time; Arkeologi;

    Abstract : This study analyzes the astronomical references found in the ancient Egyptian Coffin Texts. Chapter i presents the aim and method of this study as well as describing the primary sources and previous research. Chapter 2 deals with the conceptual background for the three cycles, as related to the year, month and the day as units of time. READ MORE

  3. 3. Oxy-Fuel Combustion Combined Cycles for Carbon Capture

    University dissertation from Stockholm : Energiteknik

    Author : Egill Maron Thorbergsson; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conceptual compressor design; oxy-fuel combustion combined cycles; Graz cycle; Carbon capture and storage; Semi-closed Oxy-fuel Combustion Combined Cycle;

    Abstract : A short and medium term method to decrease carbon dioxide emissions is carbon capture and storage. This method captures carbon dioxide from point sources of emissions and then stores the carbon dioxide in geological formations. READ MORE

  4. 4. Developing Humidified Gas Turbine Cycles

    University dissertation from Stockholm : Kemiteknik

    Author : Michael Bartlett; KTH.; [2002]
    Keywords : advanced gas turbine cycles; evaporative; humidified; power; heat and power; ;

    Abstract : As a result of their unique heat recovery properties,Humidified Gas Turbine (HGT) cycles have the potential todeliver resource-effective energy to society. The EvaporativeGas Turbine (EvGT) Consortium in Sweden has been studying thesetypes of cycles for nearly a decade, but now stands at acrossroads, with commercial demonstration remaining. READ MORE

  5. 5. Evaporative Cycles - in Theori and in Practise

    University dissertation from Per Rosén, Ole Römers Väg 1, Box 118, SE-221 00 Lund, Sweden

    Author : Per M Rosén; Lunds universitet.; Lund University.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motors and propulsion systems; Trigeneration; Combustion Engines; Gas Turbines; CHAT; HAM; HAT; Evaporative Cycles; EvGT; Motorer; framdrivningssystem; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik;

    Abstract : The thesis is based on applied research, rather closed to industrial development. The developed simulation model, for pre-design of evaporative gas turbine cycles, has been validated in a 600 kW pilot plant and in rebuilt turbo-charged diesel engines. READ MORE
