2. 1. Transmission of waves through elastic and viscoelastic junctions

   Author : Tomas Nygren; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Wave; elastic; viscoelastic; extensional; characteristic impedance; junction; transmission; reflection; dissipation; optimisation; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid Mechanics; hållfasthetslära;

   Abstract : Transmission of extensional waves through elastic and viscoelastic junctions between elastic and collinear bars have been studied theoretically and experimentally. The models used can be interpreted also for other types of waves (e.g. dilatational waves, shear waves, electromagnetic waves) and systems. READ MORE

4. 2. Elastic Neutron Scattering at 96 MeV

   Author : Joakim Klug; Jan Blomgren; Arjan Plompen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; neutron; detection; CsI; elastic scattering; differential cross section; optical potential; kerma; Kärnfysik; Nuclear physics; Kärnfysik; Applied Nuclear Physics; Tillämpad kärnfysik;

   Abstract : A facility for studies of elastic neutron scattering in the 50–130 MeV range has been developed. In addition to elastic neutron scattering, it has been used for (n,p) and (n,d) reaction experiments. The performance of the device has been illustrated in measurements of the (n,p) and (n,n) cross sections on 1H and 12C. READ MORE

   Abstract : ...The task that was put to the author of this thesis was to find solutions for manufacturing of single elastic micro bump contacts as well as complete elastic sockets and interconnections down to the carrier substrate. READ MORE

6. 4. Numerics of Elastic and Acoustic Wave Motion

   Author : Kristoffer Virta; Gunilla Kreiss; Anders Petersson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; finite differences; stability; high order accuracy; elastic wave equation; acoustic wave equation; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

   Abstract : The elastic wave equation describes the propagation of elastic disturbances produced by seismic events in the Earth or vibrations in plates and beams. The acoustic wave equation governs the propagation of sound. READ MORE

7. 5. Manufacture and characterization of elastic interconnection microstructures in silicone elastomer
