the dry bubble disease, caused by lecanicillium fungicola, is an important fungal disease of white button mushroom in iranian mushroom production farms. twenty-three isolates of the pathogen collected in iran and identified as l. fungicola var. fungicola, were compared for genetic polymorphism, diversity in growth rate and virulence. ten universal rice primers (urp) were used to evaluate the ge...

Many existing methods for temporal trend detection in environmental space-time data are based on grouping observations simply by geographical proximity. Such grouping is often static and thus does not account for changes in space-time data distribution. In this project we evaluate properties of the new data mining algorithm for dynamic detection of space-time patterns, TRUST, proposed by Ciampi...

alfalfa is the best known fodder crop with high ability of biological nitrogen fixation and drought tolerance in dry, pannonian region of east austria. different morphological and physiological characteristics of 18 alfalfa genotypes from different geographical origins, 8 iranian ecotypes and 10 european cultivars were evaluated under irrigated and rainfed conditions during 2006-08 cropping sea...

Data from the United Nations and the International Civil Aviation Organization Information Systems were used as a base for characterizing, classifying and comparing air transport demand and supply features of 156 countries. Relevant data from 1980 were chosen to reflect five sets of characteristics namely, air transport, 50cm-economic status, population demography, geographical and environmenta...

This article outlines similarity applied to the general environment and geographical information domains. The hypothesis is if physical and social sciences manifest similar amenities, then similarity would be a generative technique to analyse the cached information inherent in the data retrieved. Similarity is examined concerning the spatial grouping of natural kinds in a complex environment.

We investigate the determinants of geographical distances to parents. We focus on the role of family members who live outside the household (the parents themselves, and siblings), and on the distinction between the effects of life events and effects related to the timing with which these events have been experienced in the life course. We use data from the Netherlands Kinship Panel Study and li...

A formal approach to the phenomenon of perceptual grouping by proximity was investigated. Grouping judgments of random dot patterns were made by the CODE algorithm (van Oeffelen & Vos, 1982) and several related algorithms, and these judgments were compared with subjects' grouping judgments for the same stimuli. Each algorithm predicted significantly more subject judgments than would be expected...

A method for detection and description of rectilinear buildings from two or more aerial intensity images is described. The multiple images may be taken at different times under differing imaging conditions. Detection and description of buildings under these conditions is a difficult task. It is not possible to compute a dense 3-D map just by intensity correlation. Instead, we need to match feat...

Interactive grouping and filtering in software visualization tools are essential mechanisms enabling the users to build views that match the information needs of their software comprehension task at hand. In this paper we systematically survey these mechanisms in eight graph-based software visualization tools.
