Abs t rac t . The notion of institution is dissected into somewhat weaker notions. We introduce a novel notion of institution morphism, and characterize preservation of institution properties by corresponding properties of such morphisms. Target of this work is the stepwise construction of a general framework for translating logics, and algebraic specifications using logical systems. Earlier tr...

Basically, using the phrase “iterative” means there is a stepwise movement towards a (the) goal, instead of a “momentary leap” from problem to solution, where, at intervals, the situation is evaluated and necessary steps are taken to ensure the process is “on track” towards the solution. Such steps will normally be like loops, where you go backwards in the step-line and kind of “run it through ...

Shopping malls are one of the glories of metropolises with their attractive shops and a wide variety people who are walking in order to purchase goods. Location of a shopping mall is one of the critical criteria, because it can influence the success of the project. In addition, selecting an appropriate location to establish a new shopping mall is a sophisticated, time consuming and risky decisi...

With the ever-deepening economic reform and international trend of ICT application in education, the Chinese government is strengthening its basic education curriculum reform and actively facilitating the application of ICT in education. Given the achievement gap of ICT infrastructure and its application in middle and primary schools between urban and rural areas, a divide exists between the ne...

composites provide design flexibility because many of them can be moulded into complex shapes.  carbon fibre-reinforced epoxy composites exhibit excellent fatigue tolerance with high specific strength and stiffness. these properties led to their numerous advanced applications ranging from military and civil aircraft structures to consumer products. the modelling of beams undergoing arbitrarily ...

numerical methods such as boundary element and finite element methods are widely used for the stress analysis in solid mechanics. this study presents boundary element method based on the displacement discontinuity formulation to solve general problems of interaction between hydraulic fracturing and discontinuities. the crack tip element and a higher order boundary displacement collocation techn...
