The increased demand for distributed computations on big data has led to solutions such as SCOPE, DryadLINQ, Pig, and Hive, which allow the user to specify queries in an SQL-like language, enriched with sets of user-defined operators. The lack of exact semantics for user-defined operators interferes with the query optimization process, thus putting the burden of suggesting, at least partial, qu...

The paper briefly describes a basic set of special combinatorial engineering frameworks for solving complex problems in the field of hierarchical modular systems. The frameworks consist of combinatorial problems (and corresponding models), which are interconnected/linked (e.g., by preference relation). Mainly, hierarchical morphological system model is used. The list of basic standard combinato...

This current article focuses on “relation between human groups and natural disasters. Although natural disasters have caused considerable damages to the human world, but there is not enough research about the family in disasters. Family sociologists believe that changes in population, technology, modernity, politics, and mass media are effect on transforming structures, relationships, and behav...

Various definitions have been defined for the word “interoperability”; in general however, “interoperability” is a property through which the systems and organizations can communicate and cooperate. In e-government domain to establish “interoperability” among the organizations, using a suitable “interoperability” framework is inevitable. Numerous frameworks have been proposed in e-government in...
