Historical trends in face perception research during the past half century are summarized. The dual process model offered by cognitive neuroscientists to account for the perception of identity and emotion expression in the face is briefly reviewed together with supporting evidence. An ecological approach that incorporates missing pieces of face perception is offered as an additional, broader co...

This paper shows the power of randomization in designing e cient parallel algorithms for the problems of routing and PRAM emulation. We show that with randomization techniques optimal routing can be obtained for a large class of processor interconnection networks called leveled networks. This class includes well-known networks (e.g., mesh, hypercube and de Bruijn) as well as new ones (e.g., sta...

Robot navigation in poorly structured and uneven outdoor environments is an unsolved problem. Thus we present a SLAM (simultaneous localization and mapping) approach that is based on “leveled range scans”. The method is combining 3D perception with 2D localization and mapping. In this way established path planning and 2D navigation algorithms can be used in uneven terrain without the computatio...
