16. People tracking by mobile robots using thermal and colour vision
Abstract : This thesis addresses the problem of people detection and tracking by mobile robots in indoor environments. A system that can detect and recognise people is an essential part of any mobile robot that is designed to operate in populated environments. READ MORE

17. Type-II interband quantum dot photodetectors
Abstract : Photon detectors based on single-crystalline materials are of great interest for high performance imaging applications due to their low noise and fast response. The major detector materials for sensing in the long-wavelength infrared (LWIR) band (8-14 µm) are currently HgCdTe (MCT) and AlGaAs/GaAs quantum wells (QW) used in intraband-based quantum-well infrared photodetectors (QWIPs).

18. Infrared Photodetectors based on InSb and InAs Nanostructures via Heterogeneous Integration-Rapid Melt Growth and Template Assisted Selective Epitaxy
Abstract : Monolithic heterogeneous integration of III-V semiconductors with the contemporary Si Complementary Metal Oxide Semiconductor (CMOS) technology has instigated a wide range of possibilities and functionalities in the semiconductor industry, in the field of digital circuits, optical sensors, light emitters, and high-frequency communication devices. However, the integration of III-V semiconductors is not trivial due to the differences in lattice parameters, polarity, and thermal expansion coefficient. READ MORE

19. III-V Nanowire-based Infrared Photodetectors : Design, Fabrication and Characterization
Abstract : Semiconductors are the backbone of almost every electrical or optical component, one of them being photodetectors. Photodetectors are used in many applications such as digital cameras or solar panels. They can also be designed to detect the omnipresent infrared radiation, discovered in 1800, which is invisible to human eye. READ MORE

20. Exosomes and the NKG2D receptor-ligand system in pregnancy and cancer : using stress for survival
Abstract : Although not obvious at first sight, several parallels can be drawn between pregnancy andcancer. Many proliferative, invasive and immune tolerance mechanisms that supportnormal pregnancy are also exploited by malignancies to establish a nutrient supply andevade or edit the immune response of the host.
