    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical engineering; combusiton; flameless; jets in cross flow; chemiluminescence; POD; LIF; PIV; Spray; Gas Turbine; single digit NOx; Premixed Combustion; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Abstract : The notion of "global warming" has become a major public-domain concept as an environmental threat to our future on earth. Independently of the accuracy of existing prediction of combustion emissions on the climate on earth, the concept of reducing combustion emissions has been an important political driving force in imposing more and more severe restrictions on harmful emissions from combustion.

  5. 13. Swirl stabilized premixed flame analysis using of LES and POD

    Author : Piero Iudiciani; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Precessing Vortex Core; Swirl stabilization; Lean Premixed Combustion; Proper Orthogonal Decomposition; Large Eddy Simulation;

    Abstract : For environmental and human health reasons, the regulations on the emissions from combustion devices are getting more and more strict. In particular, it is important to abate the emission of pollutants deriving from combustion in gas turbines. A solution is the use of swirl stabilized, lean premixed combustion. READ MORE

  6. 14. Bariatric Surgery : Outcomes after Gastric Bypass and Duodenal Switch

    Author : Martin Löfling Skogar; Magnus Sundbom; Ville Wallenius; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Body composition; fat-free mass; resting metabolic rate; bariatric surgery; obesity; Roux-en-Y Gastric Bypass; Duodenal Switch; air-displacement plethysmography; Bod Pod; indirect calorimetry assessment; BAROS; quality of life; weight loss; diabetes; hypertension; dyslipidmia; depression; pain; antidepressants; opioids; complications; healthcare consumption; adverse events; Surgery; Kirurgi;

    Abstract : Obesity is associated with increased morbidity and mortality. A BMI >40 kg/m2 shortens life expectancy by about 10 years. The obesity related comorbidities diabetes, hypertension, dyslipidemia and sleep apnea contributes to the increased risk of cardiovascular events. There is also an increased risk of some forms of cancer (e. READ MORE

  7. 15. Control of Energy Storage Equipped Shunt-connected Converter for Electric Power System Stability Enhancement

    Author : Mebtu Bihonegn Beza; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transient stability.; energy storage; recursive least square RLS ; electromechanical oscillation; Signal estimation technique; static synchronous compensator; power oscillation damping POD ;

    Abstract : Flexible AC Transmission System (FACTS) controllers, both in shunt and series configuration, are widely used in the power system for power flow control, to increase the loading capability of an existing line and to increase the security of the system by enhancing its transient stability. Among the FACTS controllers family, the Static Synchronous Compensator (STATCOM) is a key device for the reinforcement of the stability in an AC power system. READ MORE
