2. 16. On the ECO2 multifunctional design paradigm and tools for acoustic tailoring

   Author : Juan Pablo Parra Martinez; Peter Göransson; Olivier Dazel; Jacques Cuenca; Per Wennhage; Franck Sgard; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle design; planned obsolescence; anisotropy; porous materials; sound absorbing materials; acoustic modelling; power balance; energy assessment; dissipated power.; Farkostteknik; Vehicle and Maritime Engineering;

   Abstract : Nowadays vehicle design paradigm influences not only the effectiveness of the different means of transport, but also the environment and economy in a critical way. The assessment of the consequences that design choices have on society at large are necessary to understand the limits of the methods and techniques currently employed. READ MORE

4. 17. Process Modeling of Composite Manufacturing

   Author : Mohammad Sadegh Rouhi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element Analysis FEA ; Poro-Mechanics; Polymer Composites.; Manufacturing Technologies;

   Abstract : The focus of this research thesis is toward developing a framework for holistic modeling of composites manufacturing of fiber reinforced structural composites. The processes that have been considered are Liquid Composite Molding (LCM) and Out Of Autoclave (OOA) processes, ranging from Liquid Resin Infusion (LRI) and Resin Transfer Molding (RTM) in LCM processes, to Vacuum Bag Only (VBO) and Evac prepregs in OOA processes.

5. 18. Mechanical activation of hematite using different grinding methods with special focus on structural changes and reactivity

   Author : Parviz Pourghahramani; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

   Abstract : The mechanical treatment of solids is one of the most common and widely used operations which man has been concerned from the very beginning of the history of civilization. Nowadays, mechanical activation has a wide range of application potentials. READ MORE

6. 19. Light scattering and absorption in pigmented coatings : Theory and experiments

   Author : William E. Vargas; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

   Abstract : Radiative transfer models are used to describe optical properties of polymericthick films containing spherical inhomogeneities with sizes comparable to thewavelength of the incident radiation. From Lorenz-Mie theory various parametersrelated to elastic light scattering and absorption by single particles are calculated, i.e. READ MORE
