Abstract Accurate mensuration of forest stands for pre-harvest planning will pose high costs if carried out by a professional forester as an on-site evaluation. The could be reduced person with limited expertise collect the required data using smartphone-based system such TRESTIMA® Forest Inventory System. Without prior information, field sample sufficient number measurement points over whole s...

In 1984 and 1987, demersal trawl surveys of fish stocks in the western and central Gulf of Alaska were executed by the National Marine Fisheries Service in cooperation with the Fisheries Agency of Japan. Details of the survey design and sampling methods are presented. Fishing power differences resulted from differences among vessels, gears, and trawling procedures. Chartered fishing vessels fro...

Empirical models are standard tools in forest management. They provide quantitative information for management and planning that is accurate within the limits of sampling and measurement accuracy, but they are generally site-specific and cannot simulate the results of changing conditions. Mechanistic, or process-based models, based on the physiological processes that govern tree growth can, in ...

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 ...
