This paper presents an alternative view on propositional dis-junctive logic program: Disjunctive program = Control program + Horn program. For this we introduce a program transformation which transforms a disjunctive logic program into a Horn program and a so called control program. The control program consists of only disjunctions of new propositional atoms and controls the \execution" of the ...

Many runtime verification tools for the Java virtual machine rely on aspect-oriented programming, particularly on AspectJ, to weave the verification logic into the observed program. However, AspectJ imposes several limitations on the verification tools, such as a restricted join point model and the inability of weaving certain classes, particularly the Java and Android class libraries. In this ...

The importance of correctness of systems is becoming more crucial as computers control more of our everyday activities. Various approaches have been advocated and used for the verification of such correctness, with one of the more promising ones being runtime verification. One important issue in runtime verification is the logic used to specify properties, since this influences both the overhea...

In this paper, we introduce a Foundational Proof-Carrying Code (FPCC) framework for constructing certified code packages from typed assembly language that will interface with a similarly certified runtime system. Our framework permits the typed assembly language to have a “foreign function” interface, in which stubs, initially provided when the program is being written, are eventually compiled ...

A Concurrent Prolog compiler, whose target language is (sequential) Prolog, was implemented in Prolog. The object program obtained can further be compiled into machine codes by a Prolog compiler. Due to the similarity among the source, target and implementation languages, the compiler and the runtime support were small and very rapidly developed. Benchmark tests showed that (twice) compiled Con...

Due to Technology scaling the importance of leakage power has significantly increased in the modern day system-on-chip devices. The runtime leakage component during the active state is almost becoming equal to the standby leakage component. Hence Present day research is more focused on reduction of runtime leakage current .we present a novel runtime leakage reduction for 70nm technology. As an ...

Formulae of linear temporal logic (LTL) can be used to specify (wanted or unwanted) properties of a dynamical system. In model checking, the system’s behavior is described by a transition system, and one needs to check whether all possible traces of this transition system satisfy the formula. In runtime verification, one observes the actual system behavior, which at any time point yields a fini...

In this paper we present an algorithm for performing runtime verification of a bounded temporal logic over timed runs. The algorithm consists of three elements. First, the bounded temporal formula to be verified is translated into a monadic first-order logic over difference inequalities, which we call monadic difference logic. Second, at each step of the timed run, the monadic difference formul...
