However, the answers to these questions are far from trivial because these depend on whether the purpose is just interpolation or also estimation of the semivariogram, on whether ancillary information is available, and on the shape and size of the area and the degree and pattern of spatial variability of the soil property. It gets even more complicated when accesibility and travel time must also be taken into account when choosing the optimal design (these factors would be particularly important in remote and inaccesible areas such as in Africa or parts of Latin America). In this MSc thesis you choose a study area and soil property and define a criterion against which sampling designs can be evaluated. Next you derive one or multiple sampling designs that optimize the chosen criterion. Common sampling designs are regular, random, stratified random and nested designs, but combinations of these designs are also used. Ideally you will also collect field data and apply geostatistical interpolation to create maps of the soil property for the chosen design(s), but alternatively you may also use synthetic datasets to evaluate the performance of multiple sampling designs. If field data collection is part of the thesis work, then the study area and soil property must be chosen such that fieldwork is indeed possible.

Anything new about stirling engines in Cal?
Looking for an update. Everything I find from google news is almost a year old. This is from the stirling engine deal with Southern Edison to build a 500MW plant outside of LA.
What geographical areas are best suited for a solar dish farm?
The southwest region of the United States is ideally suited for this. In fact, a solar farm 100 miles by 100 miles could satisfy 100% of the Americaâs annual electrical needs. Solar technology primarily addresses the peak power demands facing utility companies in the Southwest U.S. and other solar-rich areas.
The cost of living and job markets are better than the national average, but the best job strategy is not to go for averages, but look at your specific skills and experiences, figure out which careers that relates to, and then go to that geographical area:
technology - Silicon Valley
finance - New York
There are other factors to consider. How important are mountains? the ocean? good weather? I have met many midwesterners in Acapulco during the winter, and none ever told me
"I got to get back to Omaha. I just miss those snow covered plains."
4,000 Year Old Greenlander
WASHINGTON (Reuters) â Scientists have sequenced the DNA from four frozen hairs of a Greenlander who died 4,000 years ago in a study they say takes genetic technology into several new realms.
Surprisingly, the long-dead man appears to have originated in Siberia and is unrelated to modern Greenlanders, Morten Rasmussen of the University of Copenhagen and colleagues found.
"This provides evidence for a migration from Siberia into the New World some 5,500 years ago, independent of that giving rise to the modern Native Americans and Inuit," the researchers wrote in Thursday's issue of the journal Nature
