1. 16. Head Injuries in Car-to-Pedestrian Accidents - Investigation of Head Impact Dynamics, Injury Mechanisms and Countermeasures

   Författare :Jianfeng Yao; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; accident analysis; head injury; head protection; mathematical simulation; accident reconstruction; injury mechanism; Pedestrian accident;

   Sammanfattning : The aim of this study was to investigate head impact dynamics and to establish risk functions for head injuries by mathematical reconstructions of real-world car-to-pedestrian accidents. Furthermore, an attempt was made to develop an approach for the design and evaluation of head-protective devices. LÄS MER

3. 17. Ear Reconstruction. Clinical and physiological evaluations

   Författare :Martin Öberg; Malmö Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Plastic surgery; autologous ear reconstruction; sensitivity; blood flow; digital morphometry;

   Sammanfattning : Microtia is a congenital malformation where the auricle is not fully developed. In some cases the malformation is complete and the auricle is absent. In Sweden the incidence of microtia is about 2 per 10,000 births. LÄS MER

4. 18. 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. 19. Hybrid observers for systems with intrinsic pulse-modulated feedback

   Författare :Diana Yamalova; Alexander Medvedev; Xiaoming Hu; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid systems; impulsive systems; biomedical systems; Goodwin s oscillator; observers; time-delay; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : Dynamical processes resulting from the interaction of continuous and discrete dynamics are often encountered in living organisms. Time evolutions of such processes constitute continuous variables that are subject to instant changes at discrete points of time. LÄS MER

7. 20. Hybrid observers for systems with intrinsic pulse-modulated feedback

   Författare :Diana Yamalova; Alexander Medvedev; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : This licentiate thesis deals with a special class of hybrid systems, where the continuous linear part is controlled by an intrinsic impulsive feedback that contributes discrete dynamics. The impacting pulsatile feedback signal is not available for measurement and, therefore, has to be reconstructed. LÄS MER
