1. 1. Assessing tree modeling algorithm from terrestrial laser scanning in Rumperöd mixed forest

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Stig Sand; [2023]
   Keywords : Terrestrial laser scanning; Hough transform algorithm; TreeLS; Rumperöd; Biology and Life Sciences;

   Abstract : Recent technological advancements have revolutionized tree inventory methods for the forest industry. The development of terrestrial laser scanning (TSL) and automatized tree recognition software to estimate crucial tree parameters such as diameter at breast height (DBH) has made the inventory work faster and more reliable.

3. 2. High-fidelity 3D acoustic simulations of wind turbines with irregular terrain and different atmospheric profiles

   University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

   Author : Erik Hedlund; [2016]
   Keywords : wave propagation; irregular terrain; high-order finite difference methods;

   Abstract : We study noise from wind turbines while taking irregular terrain and non-constant atmosphere into consideration. We will show that simulating the distribution of 3D acoustic waves can be done by using only low frequencies, thus reducing the computational complexity significantly. .. READ MORE

4. 3. Dynamic Creation of Multi-resolution Triangulated Irregular Network

   University essay from

   Author : Emil Bertilsson; [2015]
   Keywords : Triangulated Irregular Network; View dependent terrain generation; Level of detail;

   Abstract : Context. Triangulated irregular network (TIN) can produce terrain meshes with a reduced triangle count compared to a regular grid. At the same time, TIN meshes are more challenging to optimize in real-time in comparison to other approaches. Objectives. READ MORE
