This paper discusses a simple approach to tracking objects based solely on their color. By limiting our attention to areas of approximately uniform color on nearly Lamber-tian surfaces, we can assume that pixels corresponding to surface patches on the object form a linear, tubular distribution in color space. Performing principal component analysis on user-selected sample pixels parametrizes an...

Asian societies maintain the norm that older people should live with their children. Yet some older people live alone. This is the first study to explore social isolation, strategies of coping, and preferences about living arrangements among Chinese Singaporeans aged 65+ who live alone. Data from 19 semi-structured interviews were analyzed. The elderly people who live alone either have no other...

Consider a smart chimpanzee named M from a tribe afflicted with a form of Alzheimer’s disease. Think of M as a logspace-bounded Turing machine. M can do simple things like integer arithmetic and matrix multiplication, but M turns sullen and calls for help when asked to perform seemingly equally simple tasks, such as simulating deterministic tree and dag automata. Is M acting difficult or is she...

the power supply of remote sites and applications at minimal cost and with low emissions is an important issue when discussing future energy concepts. this paper presents modeling and optimization of a photovoltaic (pv)/wind/diesel system with batteries storage for electrification to an off-grid remote area located in rafsanjan, iran. for this location, different hybrid systems are studied and ...
