An extension of the traditional modulation transfer function (MTF), the detective MTF, is proposed for the evaluation of the resolution of X-ray imaging detectors with non-uniform efficiency on the scale of individual detector elements. The dMTF is shown to give a better representation than does the MTF of the improved resolution reported when the readout of the detectors is enhanced.

CIM is the standard formalism for modeling management information developed by the Distributed Management Task Force (DMTF) in the context of its WBEM proposal, designed to provide a conceptual view of the managed environment. In this paper, we propose the inclusion of formal knowledge representation techniques, based on Description Logics (DLs) and the Web Ontology Language (OWL), in CIM-based...

introduction: the conventional methods of dosimetry are not capable of dosimetry in such a small volume of less than one cubic millimeter. although the polymer gel dosimetry method based on magnetic resonance imaging (mri) could achieve three dimensional dosimetry with high resolution, a spatial resolution evaluation based on gel dose modulation transfer function has not been investigated yet. ...

ARM (Application Response Measurement) is an emerging standard for measuring the performance and availability of business transactions and their components. A third version of the standard, ARM 3.0, is expected to be available in the first half of 2000. Enhancements include flexible transaction registration, a loosely coupled interface for simpler programming, and native Java bindings. This pap...

This paper outlines an Architectural Model and accompanying modelling notation that addresses on the need to model management component interfaces and their business contexts in a technology neutral manner in order to promote convergence on stable, reusable solutions. The approach combines existing modelling concepts related to component-based and model-driven software development from TINA-C, ...

Most enterprises today are heavily if not completely dependent on systems for the running of the business. Applications that automate business operations are mostly based on distributed, component based architectures where advances in server side component models have considerably simplified development. The simplicity of constructing these applications has resulted in an increased complexity o...

The adoption of a policy-based approach for the dynamic regulation of a system or service (e.g. security, QoS or mobility service) requires an appropriate policy representation and processing. In the context of the Semantic Web, the representation power of languages enriched with semantics (i.e. semantic languages), together with the availability of suitable interpreters, make such kind of lang...

We describe new extensions to the CIM Metrics Model. While the previous version of the model provides a means to carry out response time measurements against an application, the scope of the work described in this paper is to define schema extensions capable of measuring and tracing distributed transactions. The model has been developed by the Application Working Group of the Distributed Manage...
