in the present study, an application of multilevel modeling approach to the input- output analysis are presented first, the regional input-output table of all provinces in iran was extracted based on the adjusted flegg location quotient method (aflq). second differentiation in the leontief technical coefficients and the backward and forward linkages among various activities and sectors of all p...

Eco-territorialist approach to spatial planning overcomes functional approaches assuming as key references man/nature co-evolution, the diverse components of living, participation inhabitants territorial governance, context not object choices but a real living subject. The context, both existing and potential heritage for settled community, is considered fundamental 'actant' in ecological trans...

Measures of distance are essential to the development of many applications, but the need for these measures to be representative is often ignored measures that truly represent the manner in which solution space is traversed are often disregarded in favour of simpler measures. With the genetic algorithm employing both unary and binary operators, it is difficult to quantify the distance between c...

This article examines opportunities and limitations regarding knowledge generation in the field of environmental health. The contention is that understanding the complexity of factors that determine the health of humans and ecosystems requires a redefinition of the traditional distribution of roles and responsibilities in scientific research. These research practices involve inter and transdisc...

Ontologies are becoming more and more important in data integration. An important problem when dealing with ontologies is the fact that they are living artefacts and subject to change. When ontologies evolve, the changes should somehow be rendered and used by the pre-existing data integration systems. In most of these systems, when ontologies change their relations with the data sources i.e. th...

Constraint Programming (CP) standardizes many specialized “global constraints” allowing high-level modelling of combinatorial optimization and feasibility problems. Current Mixed-Integer Linear Programming (MIP) technology lacks both a modelling language and a solving mechanism based on high-level constraints. MiniZinc is a solver-independent CP modelling language. The solver interface works by...
