Applicability with preservation of both curvatures

Partitions with Prescribed Mean Curvatures

We consider a certain variational problem on Caccioppoli partitions with countably many components, which models immiscible fluids as well as variational image segmentation, and generalizes the well-known problem with prescribed mean curvature. We prove existence and regularity results, and finally show some explicit examples of minimizers. Introduction In this paper we consider a variational p...

Applicability Issues with TBLT in EFL Contexts

This paper examines the theoretical rationales and practical aspects of task-based language teaching (TBLT) with particular reference to research findings in EFL/ESL contexts. The definitional scope of the term ‘task’, polarizations in terms of task vs. non-task, and its relation to different language teaching approaches have engendered conceptual and methodological ambiguities.  Moreover, fact...

Functionals depending on curvatures with constraints

We deal with a family of functionals depending on curvatures and we prove for them compactness and semicontinuity properties in the class of closed and bounded sets which satisfy a uniform exterior and interior sphere condition. We apply the results to state an existence theorem for the Nitzberg and Mumford problem under this additional constraint. Ref. S.I.S.S.A. 85/99/M (July 99)

The Applicability of Workflow Management Systems for the Preservation of Business Processes

Digital preservation research has increasingly been shifting focus from the preservation of data and static objects to investigate the preservation of complete processes and workflows. Capturing all aspects of a process to be preserved, however, is an extensive and difficult undertaking, as it requires capturing complete software setups with potentially complex setups. Further, the process migh...
