1. 16. Computational Modeling of Liquid-Phase based on Homogenization

   Författare :Mikael Öhman; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computational Homogenization; Liquid Phase Sintering; FE2;

   Sammanfattning : Liquid-phase sintering is the process where a pre-compacted powder, "green body", is heated to the point where(a part of) the solid material melts, and the specimen shrinks while keeping (almost) net shape. In the case of hardmetal, the microstructure is defined by WC-Co-particles with large pores, whereby molten Co represents the liquid phase. LÄS MER

3. 17. Multiphase continuum modeling of wood : A hybrid mixture theory approach

   Författare :Winston Mmari; Björn Johannesson; Lynn Schreyer; Linnéuniversitetet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture transport; Coupled heat and moisture; Over-hygroscopic; Hybrid mixture theory; Mixture theory; Swelling; Hygro-mechanical; Non-linear elasticity; Large deformation; Phase field crack model; Anisotropic cracking; FEM; Numerical model; Norway spruce; Wood; Porous media; Forestry and Wood Technology; Skog och träteknik;

   Sammanfattning : Wood has been used as a construction material for a very long time. The development of efficient industrial production processes of wood has expanded the use of the material with the introduction of new products, such as engineered wood products. LÄS MER

4. 18. Thermodynamic and Kinetic Investigation of the Fe-Cr-Ni System Driven by Engineering Applications

   Författare :Wei Xiong; Malin Selleby; John Ågren; Byeong-Joo Lee; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase transformation; magnetism; spinodal decomposition; stainless steel; low temperature CALPHAD; phase field; ab initio; atom probe tomography; calorimetry; SRA - E-vetenskap SeRC ; SRA - E-Science SeRC ; SRA - Energy; SRA - Energi;

   Sammanfattning : This work is a thermodynamic and kinetic study of the Fe-Cr-Ni system as the core of stainless steels. The Fe-Cr, Fe-Ni and Cr-Ni systems were studied intensively using both computational and experimental techniques, including CALPHAD (CALculation of PHAse Diagrams), phase field simulation, ab initio modeling, calorimetry, and atom probe tomography.

5. 19. The measurement of chemical persistence in the field by benchmarking : Theory and Experiment

   Författare :Hongyan Zou; Michael McLachlan; Keri Hornbuckle; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chemical benchmarking; persistence; half-lives; modeling; threshold benchmarking; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Persistence is one of the core criteria in chemical exposure and hazard assessment. It is often defined as the half-life for the removal of a chemical from a specified environment by transformation. Chemicals with long transformation half-lives may pose high risks for wildlife or humans and be subject to long-range transport to remote areas. LÄS MER

7. 20. Dynamical Modeling of Cloud Applications for Runtime Performance Management

   Författare :Johan Ruuskanen; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud computing; Performance modeling; Queueing theory; Processor sharing; Mean-field approximation; Fluid model; Microservices; Load balancing; Request cloning;

   Sammanfattning : Cloud computing has quickly grown to become an essential component in many modern-day software applications. It allows consumers, such as a provider of some web service, to quickly and on demand obtain the necessary computational resources to run their applications. LÄS MER
