In this paper we prove results relating to two homotopy relations and four homology theories developed in the topology of digital images.<br /><br />We introduce a new type relation for digitally continuous functions which call ``strong homotopy.'' Both strong are natural digitizations classical topological homotopy: difference between them is analogous 4-adjacency 8-adjacency plane...

along with breakdown of soviet :union:, political geographical system as well as meaning construction of central asia and caucasus changed dramatically. thus new structure, necessities, and actors have emerged in relations between iran and countries locating in caucasus. one of these countries is azerbaijan. iran-azerbaijan relationship is of high significance from different aspects. after azer...

Generality or refinement relations between different theories have important applications to generalization in inductive logic programming, refinement of ontologies, and coordination in multi-agent systems. We study generality relations in disjunctive default logic by comparing the amounts of information brought by default theories. Intuitively, a default theory is considered more general than ...

Brugha and Bruen (2014) raise a number of compelling issues related to the interaction between politics and policy in the global health context. The first question that their views invite is whether this is, at heart, best characterized as a benign or malign influence. Many commentators have suggested that this overlap should be discouraged (see, for example, Marseille et al 2002; Thomas & Webe...

Firms pursue diversification for sake enhancing financial performance. Some theories state positive relationship between diversification and financial performance. However, there are some theories for negative relationship about the issue. The study has filled the gap that most studies done in developed countries and there are fewer studies in developing country like Malaysia. In this study, re...

Abstract In this study, we aimed to overview the relationships of most significant international theories dealing with spatial economy, special regard endogenous resources. We examined effects and development trends economic social capital because believe that they may determine future directions strategic planning. Spatial (being focus our research) is proven have outstanding influence on soci...
