This paper reports an investigation into the use of evaluation as part of system safety research. Using a simple classification scheme based on the knowledge and evaluation components of research papers, we classify two years of papers at the IET System Safety conference. Our analysis indicates a significant mismatch between a small collection of observational research papers with strong evalua...

COTS based development impacts several issues in software development. New techniques have been proposed, or existing ones have been adapted. Several approaches have been proposed for effort and size estimation, product selection, and architectural mismatches identification. But a fundamental question must be clarified before: what is a COTS product? According to the literature a COTS seems to ...

Research has shown that the visual system's sensitivity to variations in luminance (visual contrast) within a particular area of the retina is affected in a bottom-up fashion by the ambient contrast levels in nearby regions. Specifically, changes in the ambient contrast in areas surrounding the target area alter the sensitivity to visual contrast within the target area. More recent research has...

This study presents results of subjective judgments to simulated floor impact sound to create classification scheme of heavy weight impact sound with standardized rubber ball. The floor impact sound samples were recorded in a wood-frame test house with different floor configurations and were reproduced in an anechoic chamber. Using the relationship between subjective rating and physical indices...

The primary purpose of this paper is give a classification scheme for the nonzero primes of a Prüfer domain based on five properties. A prime P of a Prüfer domain R could be sharp or not sharp, antesharp or not, divisorial or not, branched or unbranched, idempotent or not. Based on these five basic properties, there are six types of maximal ideals and twelve types of nonmaximal (nonzero) primes...

We consider non-negative solutions on the half-line of the thin film equation ht + (hhxxx)x = 0, which arises in lubrication models for thin viscous films, spreading droplets and Hele–Shaw cells. We present a discussion of the boundary conditions at x = 0 on the basis of formal and modelling arguments when x = 0 is an edge over which fluid can drain. We apply this discussion to define some simi...

High sensitivity and suitable sizes are essential for magnetic iron oxide contrast agents for cell imaging. In this study, we have fabricated highly MR sensitive magnetite nanoclusters (MNCs) with tunable sizes. These clusters demonstrate high MR sensitivity. Especially, water suspensions of the MNCs with average size of 63 nm have transverse relaxivity as high as 630 s-1mM-1, which is among th...

As molecular imaging moves towards lower detection limits, the elimination of endogenous background signals becomes imperative. We present a facile background-suppression technique that specifically segregates the signal from surface-enhanced Raman scattering (SERS)-active nanoparticles (NPs) from the tissue autofluorescence background in vivo. SERS NPs have extremely narrow spectral peaks that...

This tutorial examines how people of various cultures classify different colors as belonging together under common color names. This is addressed by examining Berlin and Kay’s (1969) hierarchical classification scheme. Special attention is paid to the additional five (derived) color terms (i.e., brown, purple, pink, orange, and gray) that must be added to Herings’ six primaries (i.e., white, bl...

Although there have been quite a number of theoretical and practical studies where axiomatic design (AD) principles have been used in the last few years, there is a lack of a comprehensive literature survey which evaluates and classifies these papers. This study provides a recognizable overview of literature on AD principles from the past 20 years and introduces a novel classification scheme co...
