第四届 国际数学与计算 会议
2017/12/20
Welcome to the official website of Fourth International Conference on Mathematics and Computing 2018. It is a premier forum for the presentation of new advances and research results in the field of Co...
PRECONDITIONING A CLASS OF FOURTH ORDER PROBLEMS BY OPERATOR SPLITTING
parabolic problems fourth order problems preconditioning
2015/12/11
We develop preconditioners for systems arising from finite element discretizations of
parabolic problems which are fourth order in space. We consider boundary conditions which yield
a natural ...
Coastal Geological Oceanographers Provide the Fourth Dimension
Fourth Dimension Oceanographers
2015/8/13
The coastal ocean, defined here as waters covering the continental margin, has become an area of intense study. A driving impetus always has been to understand the complex oceanographic transitions be...

This is nominally a review of a 2001 publication, the NOAA Diving Manual, Diving for Science and Technology, 4th edition, NTIS Order Number PB99-144321INQ, and available from NTIS, see www.ntis.gov/pr...
THE RISE OF THE FOURTH ESTATE: HOW NEWSPAPERS BECAME INFORMATIVE AND WHY IT MATTERED
INFORMATIVE FOURTH ESTATE
2015/7/17
A free and informative press is widely agreed to be crucial to the democratic process today.
But throughout much of the nineteenth century U.S. newspapers were often public relations tools
funded by...
In this artile we review some reent work on fourth order equations in onformal geometry of three and four dimensions. We dis uss some an existene result for a Yamabe-type equation in dimension three. ...
