In the service-oriented software environment, interactions between components are highly dependent on the exposed service interfaces. Therefore, designing an appropriate service interface is essential. In this paper, we aim to perform a comparative evaluation on three different approaches to service interface design, i.e. method-centric, message-centric and resource-centric. The evaluation is performed systematically based on a list of selected evaluation criteria. It is expected that the evaluation results may assist software architects to understand the differences between approaches and adopt the approaches wisely in the service interface design.

In this paper we propose a smart repeater that consumes less energy and is suitable for driving global interconnections in nanometre technologies. When there is coupling between interconnects, the effective capacitance of a given wire is a function not only of the physical geometry, but also the relative switching pattern described by the bits on the wire in question (the victim) and the adjacent wires (aggressors). The drive strength of a traditional repeater is static, resulting in a spread of the propagation delay, with the repeater strength being essentially too much for every bit pattern other than the worst-case pattern. In the proposed SMART repeater, the drive strength is dynamically altered depending on the relative bit pattern, by partitioning it into a Main Driver and Assistant Driver. For a higher effective load capacitance both drivers switch, while for a lower effective capacitance the assistant driver is quiet. By disconnecting part of the repeater when it is not needed, the total load capacitance to the previous stage is reduced, resulting in reduced energy consumption for those instances. It is shown that the potential average saving in energy can be as much 15% with a 18% jitter reduction over a traditional repeater for typical global wire lengths in nanometre technologies.

Digital watermarking medical images provides security to the images. The purpose of this study was to see whether digitally watermarked images changed clinical diagnoses when assessed by radiologists. We embedded 256 bits watermark to various medical images in the region of non-interest (RONI) and 480K bits in both region of interest (ROI) and RONI. Our results showed that watermarking medical images did not alter clinical diagnoses. In addition, there was no difference in image quality when visually assessed by the medical radiologists. We therefore concluded that digital watermarking medical images were safe in terms of preserving image quality for clinical purposes

This paper describes the fundamental concept of analysis and design strategy for an effective deployment of wireless communications for innovative universities or colleges campus that insistently deploys the wireless networks. The extensive use of wireless technologies in university campus has made various respective computer applications such as electronic transactions and electronic learning (e-learning) environments become more energetic. Usually, for the innovative campus network, when deploying wireless communications, most IT Managers/Engineers begin the project by jumping into technical matters, such as deciding upon which approach, technique or standard to use, which vendor to select, and how to overcome the various limitations. These are important elements of implementing wireless communications for innovative campus;however prior to getting too far with the project, the respective IT Managers/Engineers must give vigilant attention to analysis and design strategy in order to wind up with an effective deployment.
