This paper reports on the implementation and the experiments with symbolic model checking of continuous-time Markov chains using multi-terminal binary decision diagrams (MTBDDs). Properties are expressed in Continuous Stochastic Logic (CSL) [7] which includes the means to express both transient and steady-state performance measures. We show that all CSL operators can be treated using standard o...

In this paper we investigate a potential use of fluid approximation techniques in the contextof stochastic model checking of CSL formulae. We focus on properties describing the behaviourof a single agent in a (large) population of agents, exploiting a limit result known also asfast simulation. In particular, we will approximate the behaviour of a single agent with atime-inhomoge...

Shear stress driven grain boundary (GB) migration was found to be a ubiquitous phenomenon in small grained polycrystalline materials. Here we show that the GB displacement shift complete (DSC) dislocation mechanism for GB shear coupled migration is still functioning even if the geometry orientation of the GBs deviates a few degrees from the appropriate coincidence site lattice (CSL) GBs. It mea...

The Computer Systems Laboratory (CSL), National Institute of Standards and Technology, hosted the eighteenth North American ISDN Users' Forum (NIUF) at its Gaithersburg, Maryland, site on June 22-25, 1993. About 230 users, implementors, and service providers of ISDN technology attended the meeting. CSL collaborated with industry in 1988 to establish the NIUF to ensure that emerging ISDN applica...

Standard static CMOS logic is responding to the requirement of high frequency and low power of digital systems. However, the digital switching noise generated by this logic is not suited for the design of performance mixedsignal integrated systems. In mixed-signal application the analog functionality can be affected by this digital switching noise and therefore resolution is degraded. The Curre...

We present a new soundness proof of Concurrent Separation Logic (CSL) based on a structural operational semantics (SOS). We build on two previous proofs and develop new auxiliary notions to achieve the goal. One uses a denotational semantics (based on traces). The other is based on SOS, but was obtained only for a fragment of the logic — the Disjoint CSL — which disallows modifying shared varia...

The logic CSL of the comparative concept similarity has been introduced by Sheremet, Tishkovsky, Wolter and Zakharyaschev to capture a form of qualitative similarity comparison between concepts and/or objects. In this logic we can formulate assertions of the form “objects A are more similar to B than to C”. This kind of assertions can be added to an ontology to express qualitative comparisons b...

This paper proposes an innovative approach to represent the Pictogram Chinese Characters. The advantage of this representation is using an extraordinary representation to represent the pictogram Chinese character. This extraordinary representation is created accordingly to the original pictogram Chinese characters revolution or transition. The purpose of this innovative creation is to assist th...
