Due to increasing water use, diversion and salinization, along with subsidence sea-level rise, deltas in arid regions are shrinking worldwide. Some of the most ecologically important include Colorado, Indus, Nile, Tigris-Euphrates. The primary stressors vary globally, but these threatened by increased storage diversion, eutrophication, wetland loss. In order make sustainable over time, some flo...

M C S THE definit ion of the different sectors of the indus t r ia l structure of an economy has to be baaed on a p ragmat ic appraisal of the preva i l ing conditions, w i t h due al lowance for adjustments and var ia t ions . if it is to be economical ly meaningful . Such an approach is needed a l l the more in the context of a g r o w i n g economy, fast developing as a result of conscious a...

In recent years, delegates to the OIE have voiced concern about the situation of many Official Veterinary Services (OVS). They emphasized the need to make these services responsive to present and future requirements of the animal industry, both in developed countries (with either market or planned economies) and in developing countries. There is broad agreement on the obsolescence of many OVS i...

The problem of translating a query specified in a user data content ontology into queries that can be answered by the individual data sources is an important challenge in data integration in e-science applications. We develop the notions of semantics-preserving query translation and maximally informative query translation in such a setting. We describe an algorithm for maximally informative que...

Character segmentation is the major step of document image analysis and optical character recognition (OCR). The character segmentation is necessary to detect all the character regions in the image document. The proposed method preprocesses the image document with edge detection techniques to enhance the character edges. Further, the watershed algorithm is implemented to identify the regions of...

Industrial applications and systems still lack in adopting the Web Services architecture. Legacy systems, either OPC-based or proprietary ones, compose a huge source of data, which can be migrated and integrated into enterpriselevel information systems. Within the context of prevailing and emerging technologies, such as HTTP, XML, SOAP, OPC and Web-enabled application servers, we propose an arc...

Context: Testing complex industrial robots (CIRs) requires testing several interacting control systems. This is challenging, especially for robots performing process-intensive tasks such as painting or gluing, since their dedicated process control systems can be loosely coupled with the robot’s motion control. Objective: Current practices for validating CIRs involve manual test case design and ...
