Common conceptions of the notions of role, relationship, and collaboration in object-oriented programming and related disciplines are briefly recalled and related to each other, working towards a view that allows it to fit them all together, eventually setting the cornerstones for the definition of a truly useful and widely accepted novel programming language construct.

the balanced scorecard framework with a hierarchical, multilayer, and causal-effect structure can shed light on the growth path and pave the development steps, which in addition to monitoring the financial goals. it also considers and controls the other effective and driving factors. in this study, after reviewing the balanced scorecard, a model was proposed in addition to extract the strategic...

This study reports about the effects of three concept-mapping techniques on promoting students’ learning processes in the field of business sciences: expert map, fill-in-the-map and construct-a-map. The three techniques were used complementary to a management game and they differ in the degree of self-construction. Twenty-six ninth-grade students at a public high school took part in the study. ...

zinc is the first modelling language which supports solver and technique independence. this means that a high level conceptual model can be automatically mapped into an appropriate low level design model for a specific solver or technique. to date, zinc uses three different techniques to solve a model: constraint programming (cp), local search (ls), and mixed integer programming (mip). in this ...

background: given the increasing importance of suspended particles and reporting weather conditions in the amount of ultraviolet radiation in many countries, in this study, the data of the maximum amounts of pollution by suspended particles with the size of 10, 2.5 and1 microns (pm10, pm2.5, pm1) which were reported in 1-hour time-series and global ultraviolet index (uvi) were used to predict t...

We construct an example of a C°° map on a 3-manifold which has an invariant set with an uncountable number of components, each of which is a pseudocircle. Furthermore, any map which is sufficiently close (in the C1metric) to the constructed map has a similar set.

Probabilistic seismic hazard analysis is a technique for estimating the annual rate of exceedance of a specified ground motion at a site due to the known and suspected earthquake sources. A Monte-Carlo approach is utilized to estimate the seismic hazard at a site. This method uses numerous resampling of an earthquake catalog to construct synthetic catalogs to evaluate the ground motion hazard a...
