Over the years many guidelines have been offered as to how to achieve good quality designs. We would like to be able to determine to what degree these guidelines actually help. To do that, we need to be able to determine when the guidelines have been followed. This is often difficult as the guidelines are often presented as heuristics or otherwise not(More)
Coupling is considered by many to be an important concept in measuring design quality. There is still much to be learned about which aspects of coupling affect design quality or other external attributes of software. Much of the existing work concentrates on direct coupling, that is, forms of coupling that exists between entities that are directly related(More)
Early detection of problems within a code base can save much effort and associated cost as time progresses. One method of performing routine assessment of code with a view to pre-emption of a decline in quality is to collect software metrics associated with code size and complexity. Despite the best efforts of the last decade to establish this type pf(More)
The primary motivation for building SketchNode is to provide an environment for exploring how people use tools to create, arrange, edit and interpret graph diagrams. It has two equivalent interfaces: <i>sketching</i> and <i>diagramming</i>, so that the functional requirements and advantages and disadvantages of the differences can be studied. In this paper(More)
The campaign of 2009-2010 Northern Hemisphere seasonal vaccination was concurrent with the 2009 H1N1 pandemic. Using a hemagglutination inhibition (HAI) assay, we evaluated the immunogenicity and cross-reactivity of 2009-2010 inactivated trivalent influenza vaccine (TIV) in US adult and elderly populations. Vaccination of TIV resulted in a robust boost on(More)
The effective assessment of emerging modularization technologies plays a pivotal role on: (i) a better understanding of their real benefits and drawbacks when compared to conventional development techniques, and (ii) their effective transfer to mainstream software development. This report is intended to summarize the results of the 1st International(More)
openEHR and the recent international standard (ISO 13606) defined a model driven software development methodology for health information systems. However there is little evidence in the literature describing implementation; especially for desktop clinical applications. This paper presents an implementation pathway using .Net/C# technology for Microsoft(More)
This paper demonstrates an integrated method for studying cropland loss dynamics and the resultant impacts on sustainable development spanning the past 10 years (1996–2006) in response to rampant urban growth. This study deploys remote sensing to obtain accurate measures of cropland change information and applies GIS to examine the spatio-temporal(More)
