A usability study of online library systems: A case of Sultanah Bahiyah Library, Universiti Utara Malaysia
The purpose of this study was to investigate usability of online library systems in Universiti Utara Malaysia (UUM). This study evaluated the usability of Sultanah Bahiyah Library’s web based systems by investigating the aspects of simplicity, comfort, user friendliness, control, readability, information adequacy/task match, navigability, recognition, access time, relevancy, consistency and visual presentation. This study examined user’s views about the usability of digital libraries whereas current and perceived importance. A sample of 45 students of Master of Business Administration (MBA) has been chosen. The Sultanah Bahiyah Library’s web based systems is very important especially for students and academic staffs of Universiti Utara Malaysia. The usability of the Library’s web based systems makes students easy to connect and for that the
website should be helpful and attractive within good contents. The result found that the parallel nature of the users’ current views about the usability of digital libraries and users’ perceived importance of digital library usability allows direct comparison of all usability properties. The overall results yielded significant difference for the variables of user’s current views and perceived importance
Usability evaluation of digital libraries: a tutorial
This one-day tutorial is an introduction to usability evaluation for Digital
Libraries. In particular, we will introduce Claims Analysis. This approach
focuses on the designers’ motivations and reasons for making particular
design decisions and examines the effect on the user’s interaction with
the system. The general approach, as presented by Carroll and
Rosson(1992), has been tailored specifically to the design of digital
libraries.
Digital libraries are notoriously difficult to design well in terms of their
eventual usability. In this tutorial, we will present an overview of
usability issues and techniques for digital libraries, and a more detailed
account of claims analysis, including two supporting techniques –
simple cognitive analysis based on Norman’s ‘action cycle’ and
Scenarios and personas. Through a graduated series of worked
examples, participants will get hands-on experience of applying this
approach to developing more usable digital libraries. This tutorial
assumes no prior knowledge of usability evaluation, and is aimed at all
those involved in the development and deployment of digital libraries
Moving towards Adaptive Search
Information retrieval has become very popular over the last decade with the advent of the Web. Nevertheless, searching on the Web is very different to searching on smaller, often more structured collections such as intranets and digital libraries. Such collections are the focus of the recently started AutoAdapt project1. The project seeks to aid user search by providing well-structured domain knowledge to assist query modification and navigation. There are two challenges: acquiring the domain knowledge and adapting it automatically to the specific interest of the user community. At the workshop we will demonstrate an implemented prototype that serves as a starting point on the way to truly adaptive search
Simulations of events for the LUX-ZEPLIN (LZ) dark matter experiment
The LUX-ZEPLIN dark matter search aims to achieve a sensitivity to the WIMP-nucleon spin-independent cross-section down to (1–2)×10−12 pb at a WIMP mass of 40 GeV/c2. This paper describes the simulations framework that, along with radioactivity measurements, was used to support this projection, and also to provide mock data for validating reconstruction and analysis software. Of particular note are the event generators, which allow us to model the background radiation, and the detector response physics used in the production of raw signals, which can be converted into digitized waveforms similar to data from the operational detector. Inclusion of the detector response allows us to process simulated data using the same analysis routines as developed to process the experimental data
