We present a method for automating deductive proofs of machine-level sequential programs modeled using operational semantics. Given programs annotated by the user with assertions at cutpoints, we show how to use the operational semantics of the machine to derive the verification conditions by symbolic simulation. No verification condition generator is required, nor is it necessary to manually s...

Modern process and condition monitoring systems produce a huge amount of data which is hard to analyze manually. Previous analyzing techniques disregard time information and concentrate only for the indentification of normal and abnormal operational states. We present a new method for visualizing operational states and overall order of the transitions between them. This method is implemented to...

Problem. The most important task in the field of construction and operation subway tunnels is to solve issue assessing their technical condition. Timely detection, objective assessment development process damage defects underground structures timely elimination are key successful long-term operation. Goal. goal find causes destruction elements for analysis gaining experience prevention methods ...

This study demonstrates a three-dimensional numerical simulation of earth pressure balance (EPB) shield tunnelling using coupled discrete element method (DEM) and finite difference (FDM). The analysis adopted the actual size spoke-type EPB tunnel boring machine (TBM) consisting cutter head with cutting tools, working chamber, screw conveyor, shield. For model to reproduce in situ ground conditi...

Background Criteria for Systemic Inflammatory Response Syndrome (SIRS) are recognized as operational criteria for detecting a possible bacteriaemia. Given the sensitivity and specificity of the criteria, clinical judgment is crucial in detecting the condition. The aim of the study was retrospectively to identify clinical characteristics of patients not primarily thought of as having bacteriaemi...

Freshly prepared ZnO nanoparticles were used as an effective heterogeneous base catalyst for the synthesis of aryloximes. The conversion of arylaldehydes and arylketones into the corresponding oximes (up to quantitative yields) was achieved by simply mixing the liquid reactants and hydroxylamine hydrochloride with ZnO nanoparticles under solvent-free condition. The procedure was carried out und...

We present a hierarchically structured transaction oriented concept for a rule based active database system In LL LHL we have proposed Statelog as a uni ed framework for active and deductive rules Following the need for better structuring capabilities we intro duce procedures as a means to group semantically related rules and to encapsulate their behavior In addition to executing elementary upd...

This dissertation discusses several problems loosely related, because they all involve a verification condition generator. The Boogie language is introduced; the architecture of a verification-generator is described. Then come more interesting parts. (1) Moving to a passive form representation can be seen as an automatic transformation into a pure functional language. How to formalize this tran...
