Desirable Properties for Climbing Ropes

Design and Performance of Ropes for Climbing and Sailing

Ropes are an important part of the equipment used by climbers, mountaineers and sailors. On first inspection, most modern polymer ropes appear similar, and it might be assumed that their designs, construction and properties are governed by the same requirements. In reality, the properties required of climbing ropes are dominated by the requirement that they effectively absorb and dissipate the ...

Seven Desirable Properties for Artificial Learning Systems

We propose seven desirable properties for artificial learning systems, namely: incrementality, nonmonotonicity, inconsistency and conflicting defaults handling, abstraction, self-organization, generalization, and computational tractability. This proposed set of properties is not claimed to be complete, nor does it imply that all properties must necessarily be present in all learning models. Rat...

Desirable Properties of an Ideal Risk Measure

This paper examines the properties that a risk measure should satisfy in order to characterize an investor’s preferences. In particular, we propose some intuitive and realistic examples that describe several desirable features of an ideal risk measure. This analysis is the first step in understanding how to classify an investor’s risk. Risk is an asymmetric, relative, heteroskedastic, multidime...

Link Travel Times I: Desirable Properties

When modelling travel times and traffic flows varying over time on traffic networks it is desirable that the travel times should satisfy certain properties. This paper investigates these properties and their interrelationships, in particular, uniqueness and continuity, first-in-first-out (FIFO), causality and time-flow consistency, while assuming a single traffic type. For generality we investi...
