This paper presents the visual control flow support of Visual Modeling and Transformation System (VMTS), which facilitates composing complex model transformations out of simple transformation steps and executing them. The VMTS Visual Control Flow Language (VCFL) uses stereotyped activity diagrams to specify control flow structures and OCL constraints to choose between different control flow bra...

In the visual programming domain, the stress of research is laid on the use of visual formalism, which is considered to be more intuitive than the textual formalism, in the programming task. Some visual languages are based purely on data flow. With such languages, the execution order depends on the availability of data and it is therefore difficult to specify some programming constructs such as...

Large open source software development communities are quickly learning that, to be successful, they must integrate efforts not only among the organizations investing developers within the community and unaffiliated volunteer contributors, but also negotiate relationships with external groups hoping to sway the social and technical direction of the community and its products. Leadership and con...

IT Governance (ITG) is an important topic as US companies must now monitor ITG under the provisions of the SarbanesOxley Act (2002) (Hoffmann, 2003). Trites (2003) indicates that directors are responsible for strategic planning, internal control structures and business risk. The control environment is defined in Australian Auditing Standard AUS 402 to mean “the overall attitude, awareness and a...

Two different tools, the non-empirical resolvent analysis and the data-based dynamic mode decomposition, are employed to assess the changes induced by transpiration in the dynamics of a turbulent pipe flow. The focus is on very large-scale motions. Both analyses permit the observation of streamwise waviness in the large flow structures and how the transpiration can inhibit fluctuation in locali...

Workfow Management Systems (WFMS) are concerned with the control and coordination of operational business processes, called workflows. When workflow technology is deployed in domains where processes have simple coordinative requirements, the flow of control and data may be easily mapped onto process effectiveness. With the diversity of resources, subjects and activities in the system, ensuring ...

For many organizations, reacting to fast changes in customers’ requirements becomes keys to maintain the competitive edge in the market. However, developers must locate business logics manually in source code in order to add new requirements. This problem has caused maintenance costs to escalate while budgets and the corporate spending are shrinking. In this paper, we propose an automatic appro...

Control of projects is a core issue for organizations. Successful projects, such as information systems projects, enable organizations to develop a superior supply network and enhance the capability of operations management. A few studies have investigated the effects of control on project performance; however, complexity risk has not been integrated into the relationship between control andper...
