—Changes in recent business environments have created the necessity for a more efficient and effective business process management. The workflow management system is software that assists in defining business processes as well as automatically controlling the execution of the processes. This paper proposes a new approach to the automatic execution of(More)
s We propose a methodology for business process choreography. Our methodology provides specifications of two types of business processes (Contract Process and Executable Process), and an interface protocol to represent interoperability patterns between the processes. Through our approach, existing processes usually managed by companies' own internal WFMS(More)
process models supports flexible workflow management in a distributed heterogeneous environment. Through its modular design, the WW-flow system provides a hierarchical control scheme over complex processes and subprocesses. Implemented in Java, the workflow engine and client interfaces are portable and platform-independent. W e use the term workflow to(More)
E-business automates the overall activities of a company and allows distributed systems to communicate their information. Process automation and information sharing improve a company's productivity and responsiveness, while Business-to-Business (B2B) workflow systems electronically aid the progress of business processes among trading partners, and also help(More)
The motivation is to introduce new shape features and optimize the classifier to improve performance of differentiating obstructive lung diseases, based on high-resolution computerized tomography (HRCT) images. Two hundred sixty-five HRCT images from 82 subjects were selected. On each image, two experienced radiologists selected regions of interest (ROIs)(More)
OBJECTIVE To assess the influence of variable factors such as the size of the airway and the CT imaging parameters such as the reconstruction kernel, field-of-view (FOV), and slice thickness on the automatic measurement of airway dimension. MATERIALS AND METHODS An airway phantom was fabricated that contained eleven poly-acryl tubes of various lumen(More)
OBJECTIVE This study was designed to develop an automated system for quantification of various regional disease patterns of diffuse lung diseases as depicted on high-resolution computed tomography (HRCT) and to compare the performance of the automated system with human readers. MATERIALS AND METHODS A total of 600 circular regions-of-interest (ROIs), 10(More)
