An Interface-enriched Topology Optimization for Mitigating the Effect of Surface Flaws in 3D Brittle Structures

In this 3D fracture-based topology optimization framework, the author extended the 2D framework on tailoring fracture resistance for brittle materials (Zhang et al., 2022) to 3D. In the optimization, the topology is described by radial basis functions interpolated level set function, and the problem is solved by the Interface-enriched...

Reducing near-surface artifacts from the crossline direction by full-waveform inversion of interferometric surface waves

Seismic incoherent noise and waves scattered from objects in the crossline directions can cause 2D elastic full-waveform inversion (FWI) to produce artifacts in the resulting 2D models. We develop a complete workflow that can determine subsurface S-wave velocity (VS) models inverted from 2D near-surface seismic data more stably. We make use...

DaRen: A multi-purpose 3D indoor navigation application

This is the final report of the 2013 Synthesis Project of MSc Geomatics. The research is about the possibilities of creating the DaRen application: "A multi-purpose 3D indoor navigation application".
