1. 1. Impact of Extreme River Flows on Bridges An Application to River Lagan in Ljungby Municipality, Sweden Using HEC RAS

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Assad Mohammad Tahir; [2022]
   Keywords : HEC RAS; Extreme River Flow; River Bridges; Ljungby; Lagan; Climate Change.; Technology and Engineering;

   Abstract : The role of bridges in the transportation network has become increasingly important as they ensure the smooth and safe passage of people and goods across rivers and other bodies of water. Flowing water impacts bridges over rivers primarily in two ways: (1) Hydrodynamic forces that directly impact the structure and (2) scouring at the pier and abutment, including contraction scour.

3. 2. Ponto C4.2 Implant : Development of the surgical components of the BAHS system in cooperation with Oticon Medical

   University essay from Högskolan i Halmstad

   Author : Ibraheem Ilya; Jonathan Lager; [2021]
   Keywords : Bone anchored hearing system;

   Abstract : The purpose of this project has been to evaluate different candidate designs and make design adjustments on the implant in the bone-anchored hearing system (BAHS). This was performed to minimize the surgical procedure and at the same time contain high implant stability. READ MORE

   Abstract : In Sweden, the railway sector currently faces the challenge of developing its first high-speed railway line, in response to the need to provide faster domestic and international transport alternatives. High-speed train passages on railway bridges can cause resonance in the bridge superstructure, which induce high accelerations that should not exceed the limits stipulated in the current design code.
