Half a Million Older Californians Living Alone Unable to Make Ends Meet
Presents findings on the economic security of Californians age 65 and older, using the 2007 Elder Index, with a focus on those living alone. Analyzes data by race/ethnicity, gender, age, and county and compares income levels with the federal poverty line
Worldwide cloud cover model
Classifying worldwide cloudiness into homogeneous regions, using a satellite data set containing day IR, night IR, incoming, and absorbed solar radiation measurements on a 2.5-degree latitude-longitude grid is considered. Methods of analysis are presented
Utilization of ERTS-1 data to monitor and classify eutrophication of inland lakes
A technique is being developed for use of ERTS in estimating and monitoring trophic levels of inland lakes. Preliminary findings are that Michigan lakes and ponds of one acre or more are resolvable in bands 5, 6 and 7 of NASA MSS imagery under fair conditions (haze and 70% cloud cover). In processed imagery (CCT) smaller features, including water color patterns, are evident within some lakes of 40 acres or more. Image distortion of lake size, shape, orientation, etc. is minimal; discrimination of lakes and ponds from various wetlands is good. Subsequent ERTS and aircraft imagery will be correlated with detailed ground truth of water color and quality in eutrophic test lakes
Topological Symmetry Groups of K_{4r+3}
We present the concept of the topological symmetry group as a way to analyze
the symmetries of non-rigid molecules. Then we characterize all of the groups
which can occur as the topological symmetry group of an embedding of the
complete graph K_{4r+3} in S^3
