Distributed coding is a new paradigm for video transmission, based on the Wyner-Ziv theorem. In this thesis, a new Wyner-Ziv codec was proposed using non-binary Low-Density Parity-Check (LDPC) codes. Non-binary LDPC codes, developed for use in channel coding, have been extended for source coding to compress correlated non-binary sources, such as video. The approach is based on considering the c...

Identities ascribed to research staff in face-to-face encounters with participants have been raised as key ethical challenge in transnational health research. 'Misattributed' identities that do not just deviate from researchers' self-image, but obscure unequivocal aspects of researcher identity - e.g. that they are researchers - are a case of such ethical problem. Yet, the reasonable expectatio...
