DR-BIP is an extension of the BIP component framework intended for programming reconfigurable systems encompassing various aspects dynamism. It relies on architectural motifs to structure architecture a system and coordinate its reconfiguration at runtime. An motif defines set interacting components that evolve according rules. With DR-BIP, dynamism can be captured as inter-play dynamic changes...

Performance requirements for on-board processing of satellite instrument data are steadily increasing. This demonstrator shows how today’s SoCs for satellite payload processing can be extended with high-speed interfaces and computing power utilizing commercial dynamically reconfigurable FPGAs. Reconfigurable hardware further allows for changing or adapting payload processing during the flight m...

The Ministry of Infrastructure and the Environment of The Netherlands and Rijkswaterstaat (RWS) aim to launch a risk-driven maintenance concept named RAMSSHEEP. Engineering and consultancy companies are expected to develop the RAMSSHEEP concept in order to create better maintenance strategies. The objective is to investigate whether RAMSSHEEP can be applied as a risk-driven maintenance tool for...

The high reliability of modern engineering systems is achieved by performing predictive maintenance. Mathematical models based on stochastic timed colored Petri nets are an effective tool for developing complex production processes Industry 4.0. This article discusses the maintainability evaluation used in hierarchical net models. simulation model was built using nets, and constructed with four...

The pointing task is the process of pointing to an object on a computer monitor using a pointing device, or physically touching an object with the hand or finger. It is an important element for users when manipulating visual computer interfaces such as traditional screens and touch-screens. In this context, Fitts’ Law remains one of the central studies that have mathematically modeled the point...

Software organizations face constant pressure due to stakeholder requirements and the increasing complexity of software systems. This complexity, combined with defects in code quality failures, can pose risks To ensure is understood before maintenance, developers must spend over 60% their time modifying improving quality, which costly. study examines impact refactoring activities on maintainabi...

Software modeling is an important activity for maintenance since it can facilitate the software comprehension as well as the understanding of its activities towards evolution, correction and adaptation. In this sense, maintainability and its subcharacteristics as presented in the ISO/IEC 9126 standard should be incorporated to the artifacts produced in the modeling activity aiming at designing ...

The goal of this study is to identify breakdown that has an impact on the gas turbine engine's RAM and Six Sigma level in order assess how well engine performance through value (Reliability, Availability, Maintainability) Sigma. By gathering, compiling, categorizing, conducting analysis data information utilization engines, based actual information, descriptive method used reveal availability e...

The virtual instrument technology is going to be used in the BEPC beam diagnostic system using LabVIEW to take the automatic measurement, the beam parameter analysis and the dynamic display. In this paper, we will discuss the implementation of LabVIEW applications based on the client/server model via TCP/IP. The hardware interface to instruments and the software interface to other programs are ...
