Design and First Steps in the Development of Opalis

Integrated access to the many heterogeneous and distributed sources of Geo data is an important precondition in order to facilitate the investigation of global processes like temporal development of ecosystems. The object oriented paleoecological information system OPALIS aims to support interoperability of various data sources. While retaining the advantages of local data maintenance and forma...

First report on structure and function of Educational research; Development Centers in Iranian medical universities

Introduction. quality improvement in education is one of the aims of "3rd Five-year program of development" and Iranian Medical Educational Research & Development Centers (EDC) are founded for this reason. So it is obvious that, in our universities, this policy should be performed by these centers. This study was done, because there wasn't regular data collection system previously in order to e...

First Steps Towards a Wise Development Environment for Behavioral Models

The authors present an initial wise development framework: a development environment that proactively and interactively assists the software engineer in modeling complex reactive systems. Their framework repeatedly analyzes models of the system under development at various levels of abstraction, and then reasons about these models in order to detect possible errors, to derive emergent propertie...

First Steps in Relational Lattice

Relational lattice reduces the set of six classic relational algebra operators to two binary lattice operations: natural join and inner union. We give an introduction to this theory with emphasis on formal algebraic laws. New results include Spight distributivity criteria and its applications to query transformations.
