1. 1. Dual-Probe Shear Wave Elastography in a Transversely Isotropic Phantom

   University essay from KTH/Skolan för teknik och hälsa (STH)

   Author : Gioia Bassan; [2015]
   Keywords : Shear Wave Elastography; Transversely isotropic phantom;

   Abstract : Shear Wave Elastography (SWE) is an ultrasound based technique which is able to measure tissue stiffness through the speed of induced shear waves. Tissue stiffness is often related to pathological conditions and detecting mechanical changes can help the recognition of potential diseases. READ MORE

3. 2. Numerical simulations of energy absorbing boundaries for elastic wave propagation in thick concrete structures subjected to impact loading

   University essay from Institutionen för fysik

   Author : Daniel Olsson; [2012]
   Keywords : Numerical simulations; elastic media; wave propagation; concrete; impact loading; energy absorbing boundaries; longitudinal; primary wave; secondary wave; shear; Rayleigh damping; Rayleigh wave;

   Abstract : As many of the world’s nuclear power plants are near the end of their supposed life span a need arise to assess the components crucial to the safety of these plants. One of these crucial components is the concrete reactor confinement; to assess its condition, non-destructive testing (NDT) is an attractive method. READ MORE

4. 3. Pulsed Yb:KYW laser and UV generation

   University essay from KTH/Laserfysik

   Author : Staffan Tjörnhammar; [2010]
   Keywords : Yb:KYW; UV-generation; 343 nm; q-switching;

   Abstract : In this master thesis project, a pulsed UV laser was designed and constructed. Also, the effects of absorption in a volume Bragg grating were investigated. The laser was diode pumped and constructed with Yb:KYW as gain medium. The lasing was at a wavelength of 1029. READ MORE
