he information technology has greatly driven the development of Smart Grid, however, the risk of system operation has been significantly increased simultaneously with improving the intelligent operation level of Grid system, therefore, how to construct an efficiency evaluation model of electric power information system effectively has been becoming an important subject to be explored for many experts. And based on that, this paper presents an efficiency evaluation model of electric power information system in view of the adjacency matrix. Firstly, the attack process is divided into two stages from the perspective of an attacker, namely, selecting to attack the access points and attacking other access points; secondly, it describes the intelligent selection capability of the attacker by using the transfer probability index between the nodes; finally, it conducts the computational analysis by introducing an example, to prove the practical applications of the proposed methods.

Civil architecture energy conservation efficiency evaluation is a kind of multi-factors, multi-hierarchies and multi-criteria synthetic evaluation. Perfect civil architecture energy conservation efficiency evaluation indicators system and reasonably effective synthetic evaluation methodology are keys to do energy conservation efficiency synthetic evaluation. This paper is based on framing civil architecture energy conservation efficiency evaluation system, and uses fuzzy synthetic evaluation methodology to frame civil architecture energy conservation efficiency fuzzy synthetic evaluation model, in order to make the result of evaluation more objective and reasonable.

It’s always challenging and exciting to find topics for the readers’ advisory column, and professionals willing to write for them! I’ve been so thankful to the many professionals who have so generously given their time and shared their expertise for this column. From lessons learned, case studies and differing opinions on RA and its future, it is amazing how various and rich this area of librarianship is—and how rewarding and frustrating! In an effort to continue to provide a broad spectrum of thoughts and ideas, I asked Dr. Louise Spiteri of Dalhousie University to write for this issue. Spiteri recently completed two stages of research examining subject headings and user-generated content and how these connect with RA access points. Jen Pecoskie was Spiteri’s research partner in both studies.—Editor
