  1. 1. Transition delay in boundary-layer flows via reactive control

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Nicolò Fabbiane; KTH.; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow control; drag reduction; net energy saving; adaptive control; model-based control; optimal control; flat-plate boundary layer; laminar-to- turbulent transition; plasma actuator; direct numerical simulation; in-flight experiments; strömningsstyrning; friktionsreduktion; netto energibesparing; adaptiv styrning; modellbaserad styrning; optimal kontroll; gränsskikt öve en plan platta; laminärt till turbulent omslag; plasma aktuator; DNS; flyg prov; Teknisk mekanik; Engineering Mechanics;

    Abstract : Transition delay in boundary-layer flows is achieved via reactive control of flow instabilities, i.e. Tollmien-Schlichting (TS) waves. Adaptive and model-based control techniques are investigated by means of direct numerical simulations (DNS) and experiments. READ MORE

  2. 2. Micromechanics of softwoods in the transverse plane effects on cell and annual ring scales

    University dissertation from Stockholm : KTH

    Author : Carl S. Modén; KTH.; [2008]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING Product science Wood fibre and forest products; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING Produktforskning Träfiber- och virkeslära; TECHNOLOGY Engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik; ODONTOLOGY Biomaterials; ODONTOLOGI Biomaterial;

    Abstract : Transverse mechanical properties of wood are important in many practial applications and an interesting scientific subject. A very low transverse shear modulus has been identified in spruce, which causes large strain concentrations in wood structures. READ MORE

  3. 3. Levels and sources of organophosphorus flame retardants and plasticizers in indoor and outdoor environments

    University dissertation from Umeå : Kemi

    Author : Anneli Marklund; Umeå universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organophosphate esters; OPs; human exposure; air; dust; sewage treatment plants; sludge; oil; snow; deposition; flame retardants; plasticizers; analysis; TCEP; TPP; TCPP; TBP; TBEP; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi;

    Abstract : Global consumption of organophosphate esters (OPs), which are used as flame retardants and plasticizers, is rapidly increasing. Their use as additives in diverse applications poses a risk as they may be emitted from the products they are added to and be further transported in the environment. READ MORE
