The aerospace environment imposes straight operative conditions so every electronic system usually needs to be validated for these. The same way, communication systems need to be evaluated before their introduction in aerospace applications. In the paper we present a new methodology for the evaluation of communication systems in space applications. The methodology aims, by abstraction, at ident...

Manufacturing automation systems are widespread and becoming more common across the world. Therefore, fieldbuses of automation systems in a factory plant becomes distant and dissimilar technologies from one another. Realtime interconnection between these fieldbuses is essential for the sustainability of automation. This study designs a system that provides a realtime, remote communication among...

The objective of this article is to show the application a supervision, control and acquisition system an industrial network chemical products, for which design logic architecture on Profibus-DP protocols described Ethernet, with peripheral terminal station ET-200, through Siemens CP433 programmable controller level sensor sensors, coupled radar-type transmitters accuracy ± 0.5 mm. As findings ...

Field devices in factory automation and process control systems generate time-critical, periodic, and time-available data. These data share the bandwidth of one fieldbus network medium. This paper reviews a bandwidth allocation scheme (BAS) that is applicable to many different kinds of fieldbuses. The BAS satisfies the real-time transmission requirements of time-critical and periodic data, and ...

Throughout the LHC project fieldbuses will be required to connect and control equipment and devices of various types. It will be necessary to integrate both industrial equipment and custom designed devices. In order to increase efficiency of resources a CERN working group recommends restricting the choice of fieldbuses, to be used in the years to come at CERN and by the various institutes colla...

The present study investigates the possibility of using poloxamers as solubility and dissolution rate enhancing agents of poorly water soluble bioactive constituent patchouli alcohol (PA) that can be used for the preparation of immediate release pellets formulation. Two commercially available grades poloxamer 188 (P 188) and poloxamer 407 (P 407) were selected, and solid dispersions (SDs) conta...
