This 250-page document will answer all your HYDRUS queries, especially those that are neither addressed in the Technical Manual nor in the on-line Help. It is accompanied by a CD that includes over 100 examples. The book is structured into 8 major parts: 1 - Introductory tutorial examples 2 - A detailed journey through HYDRUS windows. 3 - Simulating plant water uptake. 4 - Includes 13 advanced examples that cover soil science and engineering applications. 5 - A comprehensive section on inverse parameter estimation. 6 - Trouble shooting helps achieve trouble-free simulations. 7 - Appendixes cover theoretical background and tutorial examples on solute transport. 8 - Windows index. You can easily find your way through this document by accessing two types of indexes; a traditional alphabetical index, and a windows-index that describes over 90 HYDRUS windows. The indexes direct you to relevant pages as well as related examples. Although this document is aimed at HYDRUS-2D users, HYDRUS-1D users may also benefit from information on boundary conditions and their meaning, handling output files, simulations on root water uptake, inverse modelling (examples on root water uptake and inverse work are basically 1-D runs set in a 2-D environment), trouble shooting, and generic theoretical background information. The example projects and their results can be viewed on a demo-version of HYDRUS-2D, which is freely available on the distribution CD and downloadable from the web. Please find the time to read through the attached 'pdf' file or visit http://typhoon.mines.edu/software/igwmcsoft/hydrus_book.htm THANK YOU The HYDRUS-Manual Team Price: US$80 (excludes postage & handling) FOR ORDERS Email: hydrus@optusnet.com.au Fax: 61 7 3376 7454 ----------------------------- From: Hans Schneider Subject: LAA announcement Date: Fri, 18 Apr 2003 LINEAR ALGEBRA AND ITS APPLICATIONS Special issue on Positivity in Linear Algebra Call for papers (Reminder) Positivity in linear algebra arises in many different forms and flavors. It includes the study of matrices with nonnegative entries (Perron-Frobenius theory), matrices with positive principle minors (P-matrices, positive definite matrices, totally positive matrices), as well as linear maps with characteristics that generalize or combine these notions of positivity (e.g., positive operators, cone preserving maps). The applications of positivity as a linear algebraic notion are indeed numerous, ranging from the physical and social sciences to other mathematical areas like graph theory, optimization, stochastic processes, statistics, dynamical systems and numerical analysis. The benefit is mutual as many advances in these areas are being achieved with the aid of linear algebra and its notions of positivity, which in turn are enriched by ideas, challenges and goals for the future. For this special issue, we are looking for papers that primarily advance knowledge about positivity in linear algebra and the associated matrix classes, or that extend the reach of their theory in applications and in other mathematical fields. Areas and topics of interest include, but are not limited to the following: Entrywise positive (nonnegative) matrices. M-matrices and their inverses. Eventually nonnegative matrices. Positive (semi-)definite matrices. Totally positive (nonnegative) matrices. P-matrices. Cone preserving maps. Positive stability. Generalizations of the above in the context of operator theory and matrix functions. All papers submitted must meet the publication standards of Linear Algebra and its Applications and will be refereed in the usual way. They should be submitted to one of the special editors of this issue listed below by 31 August 2003.
