Old age is one of the most crucial stages of human development that encompasses the dynamics of biological processes, perception, growth and development and maturity, as a natural process of life. The elderly as one of the vulnerable groups, they face different biological, psychological and social needs. As the population gets older, the elderly will need more support in their daily activities,...

Developing constraint solvers which are key requisites of constraint programming languages is time consuming and difficult. In this paper, we propose a generic algorithm that symbolically constructs rulebased solvers from the intensional definition of the constraint. Unlike the well-established “generate and test” approach, our symbolic construction approach is capable of generating recursive r...

The Open Provenance Architecture (OPA) approach to the challenge was distinct in several regards. In particular, it allows different components of the challenge workflow to independently record documentation, and for the workflow to be executed in different environments, made possible by an open, well-defined data model and architecture. Another noticeable feature is that we distinguish between...

in this paper, we aresupposed to introduce the definitions of n-fold commutative, andimplicative hyper k-ideals. these definitions are thegeneralizations of the definitions of commutative, andimplicative hyper k-ideals, respectively, which have been definedin [12]. then we obtain some related results. in particular wedetermine the relationships between n-fold implicative hyperk-ideal and n-fold...
