The implementation of software based OPCUA servers on computing platforms in actuators and sensors of the field layer remains a challenge due to the protocols high memory and bandwidth prerequisites. This paper discusses encoding aspects of OPC UA binary data representations for devices with limited random access memory and low fieldbus throughput, especially focusing on single-chip microcomputing...
A graph is used to represent data in which the relationships between the objects in the data are at least as important as the objects themselves. Over the last two decades nearly a hundred file formats have been proposed or used to provide portable access to such data. This paper seeks to review these formats, and provide some insight to both reduce the ongoing creation of unnecessary formats, and...
The image data transferred by embedded network devices directly lacks of extensibility. As different devices have different image formats, so the receivers may have difficulty in interpretation. This article proposes a method based on XML to solve this problem, researches coding and recoding of image and achieve image transferring by integrating the data into XML, finally validates the feasibility...
The old manuscripts kept in libraries are a part of the richest cultural heritage and legacy of civilizations. Digitalization is a solution for the preservation of this cultural and historical heritage, which is very difficult to handle for users. The automatic or manual transcription of old Arabic manuscripts is an inevitable stage for the indexing and the diffusion of the contents of these manuscripts,...
XML (Extensible Markup Language) describes the particular structural relationship between nodes, XML encoding scheme is to assign the unique number to each node, and realizes fast operation through the numbered structure reflecting the structure of nodes. With the expanding application fields of XML, the characteristics of each area should be reflected in the encoding process of XML. This paper analyzes...
