Today’s concept of art is intimately linked with creativity. The type of political system affects creativity: an authoritarian system tends to yield more diversity in quality, but less diversity in the type of art produced. Centralized political systems tend to favour large ‘monuments’. By way of contrast, a federal system increases artists’ freedom by offering multiple sources of support. Gove...

Learners and tutors in cooperative learning environments need a shared tool for preparing material, taking notes and exchanging thoughts synchronously. To this aim, we developed a Java tool, the Shared Multimedia Notebook, which supports shared user operations on static and time-based media objects. Cooperative tasks are supported by enabling collaborative interaction among users and offering p...

 Creating Sustainable Organizations : preparing social entrepreneurs to serve as directors of Partners Centers in their own countries. Partners' ensures that the independent Centers achieve sustainability within three years by developing diverse streams of Center revenue based on a detailed assessment of their countries' needs for change and conflict management services. The Partners Network o...

This paper describes a unified approach to version control of documents and configurations. Hierarchical structure, which is present in most documents such as programs, is recognized and utilized in a fine-grained version control system. The same mechanism is used for version control of configurations and extended to handle DAGs as well as trees. Change propagation within one hierarchical docum...

An optical cross-connect architecture based on wavelength routing is proposed. The design utilises an input waveband conversion stage followed by an arrayed waveguide grating (AWG) to enable optical switching and an output single wavelength conversion stage for wavelength assignment and regeneration. Arranging the AWG in feedback or foldback loop configuration the requirement for an output mult...

TOSCA is a new OASIS standard to describe composite applications and their management. The structure of an application is described by a topology, whereas management plans describe the application’s management functionalities, e. g., provisioning or migration. Winery is a tool offering an HTML5-based environment for graph-based modeling of application topologies and defining reusable component ...

Addition of lithiated dithianes to diaryl ketones, potential electron-transfer sensitizers, disrupts conjugation between the two aromatic moieties, effectively masking the sensitizer. A novel photoamplification strategy is developed based on photosensitized cleavage in such adducts, where each fragmentation event releases more diaryl ketone, capable of sensitization. As a result, mass release o...

This paper describes a framework supporting the development of open collaboration environments which integrate heterogeneous business services. The framework facilitates the user cooperation in the execution of shared activities by offering a workspace awareness support which abstracts from the business services employed to operate. The management of the workspaces of the user’s collaborations ...

Layout design problem is one of the useful field of study used to increase the efficiency of sources in organizations. In order to achieve an appropriate layout design, it is necessary to define and solve the related nonlinear programming problems. Therefore, using computer in solving the related problems is important in the view of the researchers of this area of study. However, the designs pr...
