Computer tools for spatial analysis of plant genetic resources data: 1. DIVA-GIS The DIVA-GIS software allows analysis of genebank and herbarium databases to elucidate genetic, ecological and geographic patterns in the distribution of crops and wild species. It useful for scientists who cannot afford generic commercial GIS software, or do not have the time to learn how to use it, and for others...

The geographic distribution of Astragalus L. (Fabaceae) was analyzed using a database of 12377 geo-referenced observations. In the old world (including Asia, Africa and Europe) there are ca. 2900 euploid species classified in 166 distinct sections. In this study using geographic information system (GIS) by means of DIVA-GIS (ver. 4) distribution map of some more important sections in the old wo...

The noadeterministic divide partitions a vector into two nonempty slices by allowing the point of division to be chosen nondeterministically. Support for high-level divide-and-conquer programming provided by the nondeterministic divide is investigated. A diva algorithm is a recursive divide-andconquer sequential algorithm on one or more vectors of the same range, whose division point for a new ...

There are three major objectives of this DiVA transition effort: 1) Conduct diver visibility experiments in a range of optical water types to obtain a database for testing and refining the DiVA model; 2) Develop a Monte Carlo model that will be used to perform computer experiments of the DiVA for any combination of water optical properties, environmental conditions, and various types of underwa...
