  2. 1. Local magnetic susceptometry : Visualizing functional properties of novel materials

    Author : Ziyan Gu; K. V. Rao; Robert D. Shull; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : One of the rapidly growing instrumentation technologies of late has been Surface Probe Microscopy. Since the award of the Nobel Prize in 1986, this form of instrumentation has expanded into various fascinating forms and is successfully enabling investigations at a nano-scale. READ MORE

  4. 2. Local variation in bending stiffness in structural timber of Norway spruce : for the purpose of strength grading

    Author : Min Hu; Marie Johansson; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; digital image correlation; fibre angle; high resolution; laser scanning; local stiffness; MOE profile; mode shape curvature; strain field; strength grading; structural timber; tracheid effect; Digital image correlation; fibervinkel; laserskanning; lokal styvhet; MOE-profil; töjningsfält; hållfasthetssortering; konstruktionsvirke; trakeideffekt; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Most strength grading machines on the European market use an averagemodulus of elasticity (MOE), estimated on a relatively large distance along awood member, as the indicating property (IP) to bending strength. Theaccuracy of such grading machines in terms of coefficient of determination israther low at R2 ≈ 0.5. READ MORE

  5. 3. Aspects on ventilation induced stress and strain on regional and global inflammation in experimental acute respiratory distress syndrome

    Author : Jaime Retamal Montes; Anders Larsson; Göran Hedenstierna; Alejandro Bruhn; Björn Jonson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ARDS; VILI; respiratory rate; strain; PET;

    Abstract : Mechanical ventilation (MV) is a life-saving therapy in acute respiratory distress syndrome (ARDS), a condition that affects 3000 patients/year in Sweden with a mortality rate of about 40%. However, MV may induce or worsen lung injury causing “ventilator-induced lung injury (VILI)”. READ MORE

  6. 4. Methods for material parameter estimation : global and local approach

    Author : Göran Lindkvist; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : The rapid development of computing technology has made powerful tools, such as finite element codes, available for more and more companies. The use of simulation tools, predictive engineering, is a prerequisite today in product development. READ MORE

  7. 5. Clothing Evaporative Resistance: Its Measurements and Application in Prediction of Heat Strain

    Author : Faming Wang; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal manikin; clothing ensemble; evaporative resistance; localised evaporative resistance; thermophysiological response; heat stress; heat strain; the Predicted Heat Strain PHS model;

    Abstract : Clothing evaporative resistance is one of the most important inputs for both the modelling and for standards dealing with thermal comfort and heat stress. It might be determined on guarded hotplates, on sweating manikins or even on human subjects. READ MORE
