1. Gravitational lensing as a probe of the first stars and galaxies
Abstract : This thesis investigates the potential for detection and identification of primordial stars, galaxies, and supernovae at high redshift.Simulations indicate that the first Population III stars should appear in minihalos of mass M = 105-106 Msol at z ≈ 10-30. READ MORE

3. Radiation induced losses in Ytterbium doped laser materials
Abstract : In this work, two types of ytterbium (Yb) doped laser materials are studied, crys-talline Yb:YAG and amorphous Yb/Al silica in both preform and fiber. Yb is suitableas a laser ion because of its simple energy level structure and low quantum defect. READ MORE

5. Multi-robot Information Fusion : Considering spatial uncertainty models
Abstract : The work presented in this thesis covers the topic of deployment for mobile robot teams. By connecting robots in teams they can perform a better job than each individual is capable of. It also gives redundancy, increases robustness, provides scalability, and increases efficiency. READ MORE
