The algorithm is tested with different DEMs, and its efficacy is demonstrated through the replication of the original vector drainage pattern, derivation of geomorphic attributes that are independent of tested DEM scale, and the visualization of monotonically decreasing longitudinal stream profiles.
If Xenophanes can be seen as a founder of rational theology, then Parmenides' distinction among the principal modes of being and his derivation of the attributes that must belong to what must be, simply as such, qualify him to be seen as the founder of metaphysics or ontology as a domain of inquiry distinct from theology.
Future plans for HUI include the development of a web-based system for questionnaire administration, automatic derivation of single-attribute levels and utility scores, and with results returned in real-time to the client/researcher.
As a soft computing tool, rough set theory has become a powerful mathematical framework for pattern recognition, attribute value representation model to describe the dependencies among attributes, evaluate the significance of attributes, derivation of decision rules and knowledge discovery.
Figure 1 illustrates the HUI components showing the flow of information about a study subject collected via a questionnaire, through the derivation of health status attribute levels and utility scores, to estimate quality adjusted life years (QALYs).
In this report, we derive and test a computerized method to estimate the pretest probability of acute disease by matching the clinical characteristics (or attributes) of a patient of interest to an identical profile of attributes shared by a group of patients with known outcomes contained in a large derivation database.
Theories on the generation of basaltic magma mainly attribute its origin to the derivation of heat from within peridotite rather than by some outside source such as the radioactive decay of uranium, thorium, and potassium, which are only of minor consequence.
Quantitative characterisation of landscapes through derivation of landscape indices helps to define landscape composition, but provides limited insight into configuration attributes.
