Text to diagram conversion is an emerging area of research towards automating solution of natural language scientific problems, developing intelligent tutoring tools and many other graphics-based applications. There are no standard tools for evaluating diagrams produced from textual description. This paper presents application of an algorithmic approach to evaluate geometry diagrams produced fr...

In this paper, we consider incremental development of state transition diagrams by adding features, which add new states and transitions. The goal is to capture when properties of a state transition diagram are preserved when adding a feature. We classify several typical cases of such state transition diagram extensions and show when commonly used properties are preserved. In some cases, we add...

Can software maintainability be assessed at the early design stage? For a preliminary answer, we conducted a case study. The study adopts a set of metrics for class diagram measurement, and defines three indices for maintainability assessment from the defect-correction perspectives. The dataset under investigation includes the defect repository and corrective maintenance history of Apache Tomca...

In this study, a real and significant industrial problem in a steam power plant was investigated. Reheater tubes in boilers are under the creep and the fireside corrosion mechanism that cause some of them to fail. Since the estimation of probability of failure (PoF) and remaining life (RL) is expensive and time consuming in the deterministic methods, in this work they were evaluated using struc...

this paper is based on the initial ideas of a research proposal which will investigate SCADA failures in physical infrastructure systems. The results will be used to develop a new notation to help risk assessment using dependable computing concepts. SCADA systems are widely used within critical infrastructures to perform system controls and deliver services to linked and dependent systems. Fail...

This paper describes an algorithm (Fast Zone Discrimination FZD) for analysing Concrete Euler diagrams and listing all present zones. One application area of Euler/Spider diagrams, is modelling failure modes in electronic circuits. For this a procedure is required to check Spider diagrams for logical consistency by ensuring that all present zones in a model have been considered. Unused zones co...

Recently a lot of evidence that there exists a critical end point (CEP) in the QCD phase diagram has been accumulating. However, so far, no reliable equation of state with the CEP has been employed in hydrodynamical calculations. In this article, we construct the equations of state with the CEP on the basis of the universality hypothesis and show that the CEP acts as an attractor of isentropic ...

Failure analysis on the fishing vessel's main engine is one of works that must be completed because it crucial for operation ship. Analysis determining cause and effect failure fuel system goal this study. FMEA (Failure Mode Effect Analysis) a method used to determine priority components in failure.
