Versioning in web service development has not been adequately addressed so far. In this article, we propose extensions to WSDL and UDDI to support versioning of web service interfaces at development- and run-time. We address service- and operation-level versioning, service endpoint mapping, and version sequencing. We propose annotation extensions for developing versioned web services in Java. We have tested the proposed solution for versioning in two real-world environments and identified considerable improvements in service development and maintenance efficiency, and improved service reuse.

This paper presents an original method of data resources integration within diagnostic processes using semantic web technologies. Presented integration model allows optimization of the diagnostic process in terms of both higher quality of process execution, as well as in terms of economic efficiency. A developed innovative model in this publication is used to optimize the process of diagnosing pediatric patients, which allows for easier preventive diagnosis and improves the possibility of faster detection of problems in young children.

This article proposes specific extensions for WS-BPEL to support versioning of processes and partner links. It introduces new activities and extends existing ones, including partner links, invoke, receive, import, and on-message activities. It proposes version-related extensions to variables and introduces version handlers. The proposed extensions represent a complete solution for process-level and scope-level versioning at development, deployment, and run-time. The proposed approach has been tested in real-world environment. It solves major challenges in BPEL versioning.

The paper presents research into line centre detection using a video positioning system, as part of a measuring system for line scale calibration. In the described approach, the video positioning system processes an image taken by a CCD camera to estimate the position of the observed line's centre. The outcome of the research is mathematical models that can be used as a base for developing a positioning algorithm that is simple and adaptable to different types of line scales.

In 2002, Hsieh et al. presented their authenticated key agreement protocol. However, Tseng et al. found a flaw in the protocol which resulted in a key compromise impersonation attack. Later, Tseng proposed his protocol conforming which conforms to all desirable security properties and is efficient. In this paper we propose two new two-party identity-based authenticated key agreement protocols. The first is based on Hsieh et al.'s protocol and makes it immune against Tseng et al.'s attack, while the second is an efficiently improved protocol based on Tseng's protocol.
