In this paper we introduce an extension of the well known Rural Postman Problem, which combines arc routing with profits and facility location. Profitable arcs must be selected and facilities must be located at both end-points of the selected arcs, and a tour must be identified that maximizes the difference between the profit collected along the arcs and the cost of traversing the arcs and inst...

In this contribution we review the possibility of establishing depositional age and tectonic settings metamorphosed carbonate rocks from continental collision zones in East African-Antarctic Orogen. The geochemical characteristics regionally distributed meta-carbonate Highland Complex (HC) Sri Lanka are considered detail compared with similar occurrences Antarctica, India, Madagascar Africa. va...

the notion of strong arcs in a fuzzy graph was introduced bybhutani and rosenfeld in [1] and fuzzy end nodes in the subsequent paper[2] using the concept of strong arcs. in mordeson and yao [7], the notion of“degrees” for concepts fuzzified from graph theory were defined and studied.in this note, we discuss degrees for fuzzy end nodes and study further someproperties of fuzzy end nodes and fuzz...

The importance of language in the changing usage of particular environments is a topic worthy of greater attention than hitherto. Fraser Island has passed through a period of intense political conflict to one in which it is dominated by the new discourse of ecotourism. It is now part of that global development in which it is claimed that tourists can become properly informed about, and become p...

karun river with a length of about 890 km is considered as a main river in the country. in this paper, types of karun’s screws regarding to the geometric factors of radius of curvature and chord length were identified by fitting circles with the arcs of the river’s axis. river’s arcs were classified into simple and compound screws. then, by formation of the database consist of topographic...
