Fifteen populations of Pimpinellifoliaeae section from the species; Rosa pimpinellifolia, R. hemispherica, R. foetida and a new species, R. abrica, were collected from eight provinces of Iran and were studied on the basis of their morphological characters. In each population five plants were randomly selected and some branches were harvested in spring and autumn for studying their vegetative an...

We present our work in progress on the Lighthouse framework, a multifaceted web-based user interface to a taxonomy of numerical software. The taxonomy provides an organized anthology of software components and programming tools needed for the construction of highly-optimized matrix algebra software. It builds upon and improves existing collections of numerical software, adding tools for the tun...

Fault detection is vital to wireless sensor networks since node death is a typical fault. One of the central challenges is to design a detection algorithm which has good performance in energy efficiency. In this paper, we propose an intelligent fault detection algorithm based on numerical taxonomy. Firstly, all nodes are divided into clusters according to their geographical distribution. Beside...

Giyen a set of individuals (be they people, paddocks, or pumpkins) each possessing a number of attributes, one can arbitrarily classify them into a number of related but distinct non-overlapping groups. However, there are two major difficullies: effecting the classification and justifying it before one's colleagues. In ecological circles one has no trouble in finding sets of more than a thousan...
