ABSTRACT To disentangle the nature of a pathosystem or a component of the system such as disease epidemics for descriptive or predictive purposes, mensuration is conducted on several variables of the physical and chemical environment, pathogenic populations, and host plants. For instance, it may be desired to (i) distinguish pathogenic variation among several isolates of a pathogen based on dis...

The research reported here investigated the reliability of the patient positioning procedure used to evaluate the upper cervical region by practitioners of the Pettibon Technique and sought to establish the range of error of measurement for mensuration. Thirty-eight subjects completed the study which included taking two series of both an anterior to posterior nasium as well as lateral cervical ...

A wide range of UAV systems used for forest research requires unified approaches to data collection. The aims determine the optimal parameters collection obtain accurate information about stands, considering cost resources its process collecting remote sensing consisted nine combinations divided into three levels overlap and spatial resolution (survey altitude) changing degree filtering a dense...

forest types mapping, is one of the most necessary elements in the forest management and silviculture treatments. traditional methods such as field surveys are almost time-consuming and cost-intensive. improvements in remote sensing data sources and classification –estimation methods are preparing new opportunities for obtaining more accurate forest biophysical attributes maps. this research co...

forest roads are directions in natural habitats that used to transport wood products, secondary forest products and recreation. constructing forest roads causes trees clearing with specified width thus lead to direct or indirect changes in forest ecosystems and forest environment. this study aims to assess the changes of diversity and richness indices in main and secondary forest roads in a par...

Crown class, an ordinal tree-level mensuration attribute used extensively by foresters, is di#icult to ass ign in thefield because def ini t ions of individual classes are confounded by ambiguous references to the position the tree in the canopy and amount of light received by its crown. When crown class is decomposed into its two elements-crown position and crown light exposure--field assignme...

The DISCUS framework is a generic reusable software architecture that provides high levels of interoperability between Imagery related applications. DISCUS is also a working government furnished testbed that integrates commercial and government software together including imagery applications, mensuration, office automation, mapping, and databases. In the DISCUS experiment we have shown that it...
