This book constitutes the refereed proceedings of the 2nd IFIP internationalconference on Computer and computing Technologiesin Agriculture held in Beijing, China on October 18-20, 2008. The IFIP series publishes state-of-the-art results in the sciences and technologies of information and communication. The scope of the series includes: foundations of computer science; software theory and practice; education; computer applications in technology; communication systems; systems modeling and optimization; information systems; computers and society; computer systems technology; security and protection in information processing systems; artificial intelligence; and human-computer interaction. Proceedings and post-proceedings of refereed internationalconferences in computer science and interdisciplinary fields are featured. These results often precede journal publication and represent the most current research. The principal aim of the IFIP series is to encourage education and the dissemination and exchange of information about all aspects of computing.

The paper describes experiments that investigated the use of auditory stimuli (speech and non-speech sound) to communicate data in two information systems. These experiments were performed under a multimedia stock control system and a multimedia e-mail tool. Experiments using the multimedia stock control information system investigated rhythms and timbre to communicate windows and their associated junctions as well as the simultaneous use of speech and sound to communicate a large amount of information to users.. Experiments using the multimedia e-mail tool investigated the use of tunes and short pitch sequences with visual stimuli to communicate information in browsing e-mail data. The paper also integrates experimental results from both systems and discusses the incorporation of auditory stimuli in interactive audio-visual or multimedia information systems. Auditory stimuli helped to communicate, complement or re-enforce information that users received via the visual channel. These auditory technologies could also benefit visually impaired users of such systems. Results also indicated that the simultaneous use of sound and speech can be useful in the design of interactive multimedia information systems. The inclusion of auditory stimuli (including speech) in the design of information systems has the potential to maximise the volume of information communicated to users. A set of empirically derived design guidelines for the auditory design of information systems are described. These guidelines include issues of presentation, classification and structure of auditory messages as part of the interface design in interactive or multimedia information systems.

The main objective of this study is to extend the potentialities of bio-computing and the tools of molecular genetics to storage, indexing, and digital image processing. The first approach is to carry out the direct coding of the digital image, with the four RNA bases A, G, C, and U. Secondly, we study the possibilities of information rearrangement in image content, from the RNA concept, by a specific preprocessing. The illustration of the potential of this process is carried out with a presegmented image. Finally, the advantages and the difficulties of the direct use of bioengineering in digital imagery will be evoked. (c) 2005 Wiley Periodicals, Inc.

The advances of informationtechnology have provided an opportunity for organizations to meet their needs by improving the system. The organization should keep the customer's trust to optimize their needs in business service and improve the service itself. Therefore, it is needed an understanding of the service computing trust. A framework of measuring the trustworthiness of service computing systems is the topic in this research. This paper reviews the service system that is represented in the direction towards developing a measurement framework. The contribution to this paper provides an understanding of service computing, service computing technologies and trusted service computing systems that will be used as a foundation for guiding the development of the measurement framework of trustworthiness of service computing system.

DRA (Digital Rise Audio) is referred to specification for multi-channel digital audio codingtechnology which was issued as a Chinese national standard in 2008. A novel 3D audio coding algorithm based on DRA is presented in the paper with a significant improvement on the coding efficiency of DRA by BWE (BandWidth Extension), MCR (Maximal Coherence Rotation) and other tools, and the subjective testing result shows the 3D audio codingtechnology can be applied to the UHD audio system at 256kbps and 384kbps per 5.1.4 channels plus 4 audio objects.

DRA (Digital Rise Audio) is referred to as specification for multi-channel digital audio codingtechnology which was issued as a Chinese national standard in 2008. There novel algorithms which are the differential Huffman, context-based Huffman and context-based arithmetic entropy coding, respectively, are presented to improve the compression efficiency of DRA entropy coding with 3%, 11.11% and 13.52% at the expense of the different implementing complexities and the intra-frame and/or inter-frame error propagation in live transmission.
