3. 22. Estimation Using Low Rank Signal Models

   Författare :Kaushik Mahata; Torsten Söderström; Mats Viberg; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parameter estimation; separable least squares; statistical analysis; viscoelasticity; subspace algorithms; spectrum estimation; Signal processing; Signalbehandling;

   Sammanfattning : Designing estimators based on low rank signal models is a common practice in signal processing. Some of these estimators are designed to use a single low rank snapshot vector, while others employ multiple snapshots. This dissertation deals with both these cases in different contexts. LÄS MER

4. 23. Numerical and Experimental Studies of Deployment Dynamics of Space Webs and CubeSat Booms

   Författare :Huina Mao; Gunnar Tibert; Arne Nordmark; Anders Eriksson; Keith Seffen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deployable structure; Space web; Centrifugal force deployment; Deployable boom; Bi-stable tape spring; Fiber-reinforced composite; Viscoelasticity; Aerospace Engineering; Flyg- och rymdteknik;

   Sammanfattning : In this thesis, experiments and simulations are performed to study the deployment dynamics of space webs and space booms, focusing on the deployment and stabilization phases of the space web and the behavior of the bi-stable tape spring booms after long-term stowage.The space web, Suaineadh, was launched onboard the sounding rocket REXUS-12 from the Swedish launch base Esrange in Kiruna on 19 March 2012.

5. 24. QCM-D – with focus on biosensing in biomolecular and cellular systems

   Författare :Erik Nilebäck; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; QCM-D; biomolecular interactions; cell-surface interaction; glycosaminoglycans; viscoelasticity; cell morphology; Quartz crystal microbalance with dissipation monitoring; surface chemistry; protein conformation;

   Sammanfattning : The high degree of complexity in biological systems is being investigated in greater and greater detail by increasingly sophisticated sensing approaches. The quartz crystal microbalance with dissipation monitoring (QCM-D) technique stands out in this context, by probing the viscoelastic properties at interfaces. LÄS MER

7. 25. Computational modeling of mechanobiology in intact and healing rat Achilles tendon

   Författare :Thomas Notermans; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Collagen; Finite element model; Mechano-regulation; Mechanical Properties; Strain; Oxygen; Viscoelasticity;

   Sammanfattning : Tendons fulfill an important musculoskeletal function by enabling energy-efficient force transmission between muscles and bones. The tendon is a collagen-rich connective tissue that adapts to mechanical loading through mechanobiological processes. LÄS MER
