1. Shear and Torsion Interaction in Prestressed Hollow Core Slabs
Abstract : There are many applications in which hollow core units are subjected to combined torsion and shear, for example in floors supported on three edges and in floors with openings. The traditional calculation method for combined shear and torsion in hollow-core units adds stresses from various sources without taking into account deformations and compatibility within the unit or restraint at the boundaries.

2. Shear and Torsion in Concrete Structures Non-linear Finte Element Analysis in Design and Assessment
Abstract : For structural design and assessment of reinforced concrete members, non-linear finite element analysis has become an important tool. However, design and assessment of shear and torsion are still done with simplified analytical or empirical design methods. READ MORE

3. Hybrid Plasmonic Devices for Optical Communication and Sensing
Abstract : Hybrid plasmonic (HP) waveguides, a multi-layer waveguide structure supporting a hybrid mode of surface plasmonics and Si photonics, is a compromise way to integrate plasmonic materials into Si or SOI platforms, which can guide optical waves of sub-wavelength size, and with relative low propagation loss. In this thesis, several HP waveguides and devices are developed for the purposes of optical communications and sensing. READ MORE
