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...

Grid Technology has proven to be a suitable means for the efficient sharing of various resources within a well–defined community. The EC–funded projects LeGE–WG and e–LeGI have set out to apply this technology for technology enhanced learning services. Previously, the applicability of distributed skill maps for adaptive e–Learning within a grid network has been discussed. In this paper, we prop...

this paper presents a method for generating a digital management map to apply cyanazine pre-emergence herbicide. the main objective was to develop a precision method to generate management maps for the variable rate application of herbicide to reduce the amount of herbicide applied and its adverse impact on the environment. first, local and utm coordinates of a field were determined using total...

| Knowledge of clusters and their relations is important in understanding highdimensional input data with unknown distribution. Ordinary feature maps with fully connected, xed grid topology cannot properly re ect the structure of clusters in the input space|there are no cluster boundaries on the map. Incremental feature map algorithms, where nodes and connections are added to or deleted from th...

This paper describes an online stereo visual simultaneous localization and mapping (SLAM) algorithm developed for the Learning Applied to Ground Robotics (LAGR) program. The Gamma-SLAM algorithm uses a Rao–Blackwellized particle filter to obtain a joint posterior over poses and maps: the pose distribution is estimated using a particle filter, and each particle has its own map that is obtained t...
