Usage control generalizes access control to what happens to data in the future (“delete after thirty days,” “do not copy,” “notify owner upon access.”) Distributed usage control is about defining and enforcing usage control requirements on data after giving it away. It is relevant in the areas of data protection, the management of intellectual property, the management of secrets, and compliance...

Umko is a strong open-source chess program developed to collect good concepts from literature and other open-source projects. Using these concepts, we want to implement an optimally chess program. To do this, Umko has implemented a bitboard representation, move generator, parallel search algorithm, multiple principal variation search, transposition table, universal chess interface, evaluation f...

The objective of this workshop was to discuss current techniques, tools and environments for learning object-oriented concepts and to share ideas and experiences about the usage of computer support to teach the basic concepts of object technology. Workshop participants presented current and ongoing research. This was the sixth workshop in a series of workshops on learning object-

Component-oriented software development has become an important approach to building complex software systems. This paper describes the component-oriented language BoxScript whose design seeks to support the concepts of components in a clean, simple, Java-based language. This paper presents the key concepts and syntax of BoxScript and how it supports compositionality and flexibility and gives a...

concepts is largely specified by their usage in language rather than by their relations to the physical world. Subjects might therefore generate an appropriate semantic sentential context to fully explore and specify the meaning of abstract concepts. Our results also explain why abstract semantics is vulnerable to left frontotemporal lesions.semantics is vulnerable to left frontotemporal lesion...

Aiming at the limitations of traditional personalization approaches, this article analyzes the approach based on ontology, and proposes its practical method. This approach retains the relationships both between attributes of concepts and between concepts, providing more flexibility in matching usage profiles with current user session, which can improve the precision and coverage of the recommen...

Due to the requirements of open service markets, the structure of networks and application systems is changing. To handle the evolving complex distributed systems, new concepts for an efficient management of such systems have to be developed. Focussing on the service level, examples for existing concepts are trading, to find services in a distributed environment, and load balancing, to avoid pe...
