State Machines Formal semantics for large part of UML using Abstract State Machines (Gurevich). Transition systems. States: multi-sorted first-order structures (set with function names and function interpretations). ASM: set of states (incl. initial state) and update rule.

Trust model is an important component of gird security model and can be classified as mission-unaware identity trust model, mission-aware identity trust model, mission-unaware behavior trust model and mission-aware behavior trust model. All of them could be regarded as projections of mission-aware behavior trust model, by which authorization depends on not only the trust but also the cost and q...

Although millions of automatic teller machines (ATMs) are currently used all over the world, users of ATMs still have usability problems including inappropriate user-ATM interaction, display problems and others. Many developed countries already have standards in place for ATMs. However, this is not the case in many other countries. This paper aims to assess certain dimensions of ATM machines an...

We define a notion of implementation for real-time Abstract State Machines (ASM) with instantaneous actions by machines with delayed actions. The time is continuous, and time constraints are metric. It is clear that not every machine of the first type can be implemented by a machine of the second type. We describe sufficient conditions on ASM that permit to construct such an implementation in a...

Over the years, economists had been taught that "Trade can make everyone better off", thus rationale of dynamic shift in Philippine agricultural trade system from protectionism to liberalization. It was known Philippines one champions agriculture sector as it massively produced goods and exports during late 20th century. However, various studies reports have shown concluded setting is now dubbe...
