How can one find real solutions (x1, x2)? How to prove that they do not exist? And if the solution set is nonempty, how to optimize a polynomial function over this set? Until a few years ago, the default answer to these and similar questions would have been that the possi­ ble nonconvexity of the feasible set and/or objective function precludes any kind of analytic global results. Even today, t...

This paper discusses neuropsychological and neurolinguistic aspects of specific language impairment (SLI), classified among the developmental speech disorders. SLI constitutes one of the more important manifestations of irregularities in the development process and is among the earliest ob served in children. SLI results from the uneven development of linguistic processes – phonological, semant...

In this work, we address the functional-unit based life cycle optimisation of the design and operations of shale gas supply chain networks considering both the economic and environmental performance. The system covers the well-to-wire life cycle of electricity generated from shale gas, consisting of a number of stages including freshwater acquisition, shale well drilling, fracking, and completi...

In an investigation of the linguistic abilities of the right or nondominant cerebral hemisphere, it is important to bear in mind the distinction between receptive (listening and reading) and productive (speaking and writing} skills. This paper attempts to highlight recent findings in neurolinguistic and psycholinguistic research on right hemisphere involvement in language function and argues th...

Several design patterns are defined to make systems more flexible and extensible. The main goal of this work is to show how the representation of this kind of patterns, which we refer to as configuration design patterns, can be vastly improved through extensions to the diagrams used to model them. An extension to the UML design notation to better represent configuration patterns is proposed and...

Relations are fundamental structures for knowledge representation. Relational queries are used to extract information from associated relations in databases. We propose to include relations in constraint programming (CP) as decision variables and promoting relational operations to constraints. That leads to new possibilities for modeling and solving CSPs. Performance and applicability are two a...
