AbstructIn this paper, we study fault-tolerant redundant structures for maintaining reliable arrays. In particular, we assume the desired array (application graph) is embedded in a certain class of regular, bounded-degree graphs called dynamic graphs. We define the degree of reconfigurability D R , and D R with distance D R d , of a redundant graph. When D R (respectively, D R d ) is independen...

Practical condition assessment and prediction of remaining useful life for electronic communication and weapon systems offers significant potential for improved readiness and field reliability of military and civilian defense systems. Modern systems, operating in the Radio Frequency (RF) spectrum, employ significant digital signal processing and data management elements central to their core de...

This study presents fuzzy logic based online fault detection and classification of transmission line using Programmable Automation and Control technology based National Instrument Compact Reconfigurable i/o (CRIO) devices. The LabVIEW software combined with CRIO can perform real time data acquisition of transmission line. When fault occurs in the system current waveforms are distorted due to tr...

There is always has been a demand to provide efficient and effective high quality software. There are various maintainability objects to provide better maintainability. The quality of good software design heavily effective the quality of software. One of the claimed advantages of object-oriented paradigm is ease of maintenance. This paper provides the review on the papers studied on the softwar...

Software maintenance is a term of major interest and it is a valuable part of software development cycle. One of the main aspects of software quality in software products is maintainability. Further, there are four sub categories of maintainability: analyzability, changeability, stability, and testability. Maintainability plays a vital role in improving software quality as software changes/upda...

Code smells are indicators of software design shortcomings that can decrease software maintainability. An advantage of code smells over traditional software measures is that the former are associated with an explicit set of refactoring strategies to improve the existing design. As such, code smell analysis is a promising approach to address both the assessment and the improvement of maintainabi...

Dynamic Probabilistic Risk Assessment (DPRA) is a powerful concept that is used to evaluate design and safety of complex industrial systems. A DPRA model uses a conceptual system representation as a formal basis for simulation and analysis. In this paper we consider an adaptive maintenance of DPRA models that consist in modifying and extending a simplified model to a real-size DPRA model. We pr...

Maintenance plays an essential role in a system’s life cycle. At the system level, the maintenance influences the reliability and availability of the system [3]. Achieving a high maintainability in the railway system requires a proper maintenance strategy. More maintenance means more life-cycle cost, while it may not lead to a dramatical improvement in the reliability. Hence, the performance of...

Nowadays, due to the concern regarding environmental issues, establishing pedestrian/bike friendly urbanism is widely encouraged. To promote safety-assured, mobile communication environments, efficient, reliable maintenance, and information integrity need to be designed, especially in highly possibly interfered places. For busy traffic areas, regular degree-3 dedicated short range communication...
