The purpose of this paper is to design a decoding software for the Reed‐Solomon (RS) codes, which are using an efficient degree computationless algorithm based on the Euclidean algorithm. As a consequence, the complexity of this new decoding algorithm is dramatically reduced.

Applying the rules of polynomial in finite field, operation modules which can carry out multiplication, inverse calculation in GF(2⁸) are designed with “C++” language, and a RS codec software based on these is implemented. In this software, the new decoding algorithm computes the error locator polynomial and the error evaluator polynomial simultaneously without performing polynomial divisions, and there is no need for the degree computation cell and the degree comparison cell.

Owing to the help of this software, the paper can easily perform the RS code for different values of t and different primitive polynomials over GF(2^m) without re‐designing the programme.

It will be served as an efficient auxiliary technique for algorithm development and verification together with hardware design and debugging. Furthermore, an illustrative example of (255, 223) RS code using this program shows that the speed of the decoding process is approximately three times faster than that of the conventional decoding software.

This paper seeks to describe efforts in the area of converting bibliographic records into Dublin Core from the Common Communication Format.

The paper provides examples of two mappings, one for unqualified Dublin Core metadata elements, and the other for qualified Dublin Core metadata elements.

Some difficulties may occur during the conversion of bibliographic records, and these difficulties are stated along with possible solutions.

The paper provides a methodology which would enable an algorithm to be developed for converting CCF‐based bibliographic records into Dublin Core metadata elements.

The purpose of this paper is to evaluate the green building certification systems. In doing so, a validation process, using confirmatory factor analysis (CFA), was undertaken.

An extensive literature review was conducted to highlight the paramount aspects of green building certification systems. Then, using a grounded theory, key findings of the initial literature review were explored. This was necessary to form a broad theoretical framework. Finally, CFA was performed to evaluate various green building certification systems.

Initially, it was noted that accreditation process was the central key for effective building certification systems, particularly at the international level. Further, using CFA, it was also determined that to increase the sustainable performance of the green building certification, meeting the increasing expectation of the system user is paramount.

When evaluating the green building certification systems, it is recommended to focus on a specific aspect of the programmes holistically. This needs to be done particularly towards delivering a clear message to the stakeholders globally; doing so may alleviate the many challenges of green building certifications.

Currently, various green building certification systems have been developed for local purposes. This raises the question of the adaptability of these systems across varying climates and geography in differing regions. Using CFA, this research will examine various green building certification systems to evaluate their applicability at a global level.
