We have devised a mammogram modeling system which greatly simplifies the development of, and can improve the accuracy and consistency of, computer-aided display and analysis algorithms for digital mammography. Our system segments the five major components of a mammogram: background, uncompressed-fat, fat, dense, and muscle. Differences in the amount and distribution of these components account ...

The analysis of capability requirements plays a very important role in military operations. It assists analysts to make decisions at strategic, operational and tactical levels. The analysis of capability requirements tends to be extremely expensive and time-consuming. Cutting-edge information technologies, such as red teaming, complex adaptive systems and agent based systems, can facilitate suc...

This paper describes some extensions to our CAVALIER agent-based simulation system, a tool for studying the performance of networked military organisations. Specifically, we have improved event handling and added neural-network-based learning. The CAVALIER tool is intended for collaborative workshops in the style of Project Albert. To demonstrate this use, the paper describes in detail an exper...

A major emphasis in software development is placed on identifying and reconciling architectural and design mismatches. Those mismatches happen during software development on two levels: while composing system components (e.g. COTS or in-house developed) and while reconciling view perspectives. Composing components into a system and ’composing’ views (e.g. diagrams) into a system model are often...

CycSecure is a network risk assessment and network monitoring application that relies on knowledge-based artificial intelligence technologies to improve on traditional network vulnerability assessment. CycSecure integrates public reports of software faults from online databases, data gathered automatically from computers on a network and hand-ontologized information about computers and computer...

introduction: health system performance assessment provides appropriate information about the status of health systems for governments and communities. therefore, in the recent decade, many countries have focused on performance assessment and reporting in order to develop methods and tools as a mean to help achieving health goals. the present study tries to design an indicator-based model (incl...

physicians are constantly challenged by their patients themedia, and the rapid pace of technological advance to keep abreast of new diagnostic and therapeutic developments. evidence-based medicine (ebm) is the practice of making updated medical decisions through the judicious identification, evaluation and application of the most relevant published information. rcts are one of the best primary ...

The 4 Diabetes Support System (4DSS) is a prototypical hybrid case-based reasoning (CBR) system that aims to help patients with type 1 diabetes on insulin pump therapy achieve and maintain good blood glucose control. The CBR cycle revolves around treating blood glucose control problems by retrieving and reusing therapeutic adjustments that have been effectively used to treat similar problems in...

Risk assessment is a crucial activity for financial institutions because it helps them to determine the amount of capital they should hold to assure their stability. Flawed risk assessment models could return erroneous results that trigger a misuse of capital by banks and in the worst case, their collapse. Robust models need large amounts of data to return accurate predictions, the source of wh...

Land evaluation is sensitive to the effects of annual variability in weather. A method to incorporate this variability into land evaluation systems is proposed, using the land capability system for Scotland as a case study. Land capability classes were found to be sensitive to the climate reference period from which data are taken. Individual stations rarely occupy their long-term land capabili...
