Purpose: The aim of the study is to compare the perceived benefits of public libraries between five culturally different countries: Finland, Norway, the Netherlands, South Korea and the U.S. Design/methodology/approach: The data was based on representative samples of Finnish, Norwegian, Dutch, Korean and American adult library users. In Finland a mail survey was used and in other countries web ...

How does the published scientific literature used by scientific community? Many previous studies make analysis on the static usage data. In this research, we propose the concept of dynamic usage data. Based on the platform of realtime.springer.com, we have been monitoring and recording the dynamic usage data of Scientometrics articles round the clock. Our analysis find that papers published in ...

The Linux kernel employs hash table data structures to store high-usage data objects such as pages, buffers, inodes, and others. In this report we find significant performance boosts with careful analysis and tuning of four critical kernel data structures.

The aim of incremental analysis is, given a program, its analysis results, and a series of changes to the program, to obtain the new analysis results as efficiently as possible and, ideally, without having to (re-)analyze fragments of code which are not affected by the changes. Incremental analysis can significantly reduce both the time and the memory requirements of analysis. The first contrib...

Throughout the 1990s, we have witnessed the burgeoning interest and rapidly advancing technologies in the "eld of information visualization (Card, Mackinlay & Shneiderman, 1999; Chen, 1999; Ware, 2000). This "eld has captured the imagination of researchers and practitioners from a wide range of disciplines all over the world. Increasingly powerful and visually appealing information visualizatio...

This paper describes an eddy current (EC) based non-destructive testing system used for experimental verification of optimized chirp signal. The time-frequency content of the EC driving signal is synthesized with respect to material properties. We are expecting an improvement in sensitivity of crack and corrosion detection.

While techniques and tools for Web marketing are being actively developed, there is much less available for Web merchandising. This paper contributes to the area of Web usage analysis for E-commerce merchandising. First, we categorize areas of analysis for Web merchandising such as product assortment, merchandising cues, shopping metaphors, and Web design features. Second, we define a new set o...

Existing ERM/DRM systems and more generally usage control systems aim to control who accesses data and the usage data is subject to even after the data has been disseminated to recipients. However, once the data has been used, no control or protection is applied to the information created as result of the usage. We propose a solution to derive protection requirements for derived data that makes...

This paper examines the metrics commonly used to assess the energy efficiency of data centres through performing and critiquing a case study calculation of energy efficiency. Specifically, the energy efficiency metric Power Usage Effectiveness (PUE), which has become a de-facto standard within the data centre industry, will be assessed. This is achieved by using open source specifications for a...

BACKGROUND Drug use among college students is associated with adverse academic and health outcomes and risks to personal safety. OBJECTIVES This study utilized data from a longitudinal study to estimate annual prevalence, cumulative lifetime prevalence, and incidence of ten types of drug use during the eight years after college entry and the average age of onset of each drug used. METHODS P...
