2. 21. Primary Marine Aerosol : Validation of sea spray source functions using observations and transport modeling

   Author : Henrik Grythe; Johan Ström; Krejci Radovan; Bo Gustafsson; Lars Ahlm; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; marine aerosol; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : Sea spray aerosols (SSA) are an important part of the climate system through their effects on the global radiative budget, both directly as scatterers and absorbers of solar and terrestrial radiation, and indirectly as cloud condensation nuclei (CCN) influencing cloud formation, lifetime and precipitation. In terms of their global mass, SSA is the largest source and has the largest uncertainty of all aerosols. READ MORE

4. 22. Exploring the Software Verification and Validation Process with Focus on Efficient Fault Detection

   Author : Carina Andersson; Institutionen för datavetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Quality is an aspect of high importance in software development projects. The software organizations have to ensure that the quality of their developed products is what the customers expect. Thus, the organizations have to verify that the product is functioning as expected and validate that the product is what the customers expect. READ MORE

5. 23. Understanding Human Mobility with Emerging Data Sources: Validation, spatiotemporal patterns, and transport modal disparity

   Author : Yuan Liao; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; travel mode; data mining; travel time; mobility; social media data; gravity model; Twitter; geographical information systems;

   Abstract : Human mobility refers to the geographic displacement of human beings, seen as individuals or groups, in space and time. The understanding of mobility has broad relevance, e.g., how fast epidemics spread globally. READ MORE

6. 24. CFD modeling of biomass combustion and gasification in fluidized bed reactors

   Author : Miao Yang; Strömningsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass combustion and gasification; CFD simulation; Fluidized bed furnace; Distribution kernel method; Empirical pyrolysis model;

   Abstract : Biomass is an environmentally friendly renewable energy source and carbon-neutral fuel alternative. Direct combustion/gasification of biomass in the dense particle-fluid system is an important pathway to biomass energy utilization. READ MORE

7. 25. Assessment of Experimental, Computational, and Combined EFD/CFD Methods for Ship Performance Prediction

   Author : Kadir Burak Korkmaz; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical friction line; form factor; CFD; measurement uncertainty; power prediction; EFD; verification and validation; Combined CFD EFD Methods;

   Abstract : In today’s highly competitive market, alongside increasingly stringent regulatory requirements, the precise prediction of ship performance has assumed paramount importance for both design verification and operational evaluations. This thesis addresses the need for a comprehensive assessment of Experimental Fluid Dynamics (EFD), Computational Fluid Dynamics (CFD), and their combination to enhance the accuracy of performance predictions.
