  2. 1. Effect of chemical and physical properties on combustion of biomass particle

    Author : Amit Biswas; Fabrizio Scala; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Biomass combustion is an interesting alternative to fossil fuel. Modeling and simulation is used for design optimization of biomass boilers and furnace. It is difficult to develop a sufficiently accurate and computationally efficient model because the combustion system is highly complicated multi-scale, multi-phase and multi-physics problem.

  4. 2. Enablement of digital twins for railway overhead catenary system

    Author : Amit Patwardhan; Ramin Karim; Rikard Granström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway catenary; Maintenance; eMaintenance; LiDAR; Point Cloud; Digital Twin; Software Architecture; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Railway has the potential to become one of the most sustainable mediums for passenger and freight transport. This is possible by continuous updates to the asset management regime supporting Prognostics and Health Management (PHM). Railway tracks and catenaries are linear assets, and their length plays a vital role in maintenance. READ MORE

  5. 3. Strategies to improve outcome after islet transplantation using the GLP-1 receptor agonist, extendin-4

    Author : Amit Sharma; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Transplantation of pancreatic islets into the liver via the portal vein has emerged as a treatment option for patients with type I diabetes mellitus. However, loss of functional beta cell mass during isolation and following implantation is a major obstacle in obtaining good long-term results. READ MORE

  6. 4. Cell response to imaging contrast agents suggested for atherosclerotic plaque imaging

    Author : Amit Laskar; Ximing Yuan; Wei Li; Rolf GG Andersson; Eva Hurt-Camejo; Linköpings universitet; []
    Keywords : ;

    Abstract : Oxysterols are the major cytotoxic components of oxidized low-density lipoprotein (OxLDL) that accumulate in atherosclerotic plaques. Their uptake by macrophages ensue foam cell formation, atherogenesis and plaque progression. READ MORE

  7. 5. Inflation and Instabilities of Hyperelastic Membranes

    Author : Amit Patil; Anders Eriksson; Arne Nordmark; Peter Hansbo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membranes; Constrained inflation; Energy release rate; Adhesive contact condition; Limit point; Bifurcation point; Wrinkling; Tension field theory; Pressure induced instability.; Teknisk mekanik; Engineering Mechanics;

    Abstract : The applications of membranes are increasing rapidly in various fields of engineering and science. The geometric, material, force and contact non-linearities complicate their analysis, which increases the demand for computationally efficient methods and interpretation of counter-intuitive behaviours.
