Publication Assessing the status of library information systems security(Sage Publications Ltd, 2013) ;Ismail, RZainab, ANThis study proposes an instrument to assess the current information system security status in libraries. The instrument is based on a model named LISSAM (library information systems security assessment model), which comprises five components: technological security foundation, information security policy, procedures and control, administrative tools, methods, and awareness creation. The instrument was pilot-tested with 50 respondents responsible for information systems or information technology in their libraries. All components received Cronbach alpha scores of <0.60 and were found to be reliable and acceptable. Findings revealed that over 95% of libraries have a high level of technological implementation but 54% scored poorly on organizational measures, especially on the lack of security policies, procedures, and user training. High scores on technological implementation were found to be correlated to sufficient financial support and early information and computer technology adoption. - Some of the metrics are blocked by yourconsent settings
Publication Evaluating Usability for Mobile Application: A MAUEM Approach(Assoc Computing Machinery, 2015) ;Saleh, A ;Ismail, RFabil, NMany traditional usability metrics were purposely created for desktop computer applications and may not be directly applicable to mobile device applications. Usability metrics refer as means of measuring or evaluating the usability factors, attributes and related measurable criteria corresponding to usability attributes. The objectives of this paper were to evaluate the usability attributes and metrics of mobile device applications by using the unsupervised usability evaluation tool. Subjective and objective measurements were used to clarify the usability metrics collected in the log file which are generated by the unsupervised usability tool. The proposed Mobile Application Usability Evaluation Metrics (MAUEM) model can provides guidance on how and what to measure for each usability attribute which could lead to a complete usability evaluation for a mobile application. - Some of the metrics are blocked by yourconsent settings
Publication Query Cost-Reduction For Quranic-Arabic Information Retrieval Using Hexadecimal Conversion Algorithm(Univ Utari Malaysia-Uum, 2017) ;Mazlan, AA ;Norwawi, NM ;Wahid, FA ;Ismail, RAl Omoush, ADigital Quran is a natural language document that use either Arabic font or images of the verses. In the Al-Quran there are 18994 unique words. Thus, the image approach uses a significant amount of memory space. However there is not much work has been done using machine translation (MT) technique for the Quranic representation. This paper will proposed Arabic information retrieval based on keywords search in Hexadecimal Representation using Al-Quran verses as the test case. All Quranic words will transliterate into machine language in the form of binary format after removing diacritic and duplication. This machine language approach in representing Digital Quran reduces the size of storage around 47-54% and retrieval time up to 20% hence reduce the query cost for Arabic information retrieval in general. - Some of the metrics are blocked by yourconsent settings
Publication Sex estimation from reconstructed scapula models using discriminant function analysis in the Malaysian population(Taylor & Francis Ltd, 2019) ;Omar, N ;Ali, SHM ;Shafie, MS ;Ismail, NAN ;Hadi, H ;Ismail, RNor, FMScapulae have been widely studied for its potential in differentiating sex in skeletal remains, especially when traditionally used sexually dimorphic bones were not available. The present work aimed to investigate sexual dimorphism of scapulae, and to develop and validate the population-specific metric standards of the Malaysian population using three-dimensional (3D) computed tomographic (CT) scapula models. Each scapula was measured for five variables with a digital caliper and analysed for independent T-test and discriminant analysis, where a leave-one-out cross-validation was applied. Moreover, a set of different samples (hold-out sample) was used to validate the established discriminant functions (DF). Consequently, all measurements showed significant differences between males and females (p < 0.001) and morphological breadth was discovered as the most sexually dimorphic scapulae measurements. Six DFs with classification accuracy ranging from 84.4% to 93.1% were generated. From the functions, stepwise DF predicted the highest classification accuracy. Additionally, the stepwise DF exhibited 95% classification accuracy when tested on the hold-out sample compared to univariate DFs which showed 82.5-92.5% accuracy. In conclusion, the virtual 3D scapulae models were sexually dimorphic, and the discriminant functions were significant in identifying skeletonized remains using scapulae bone in the Malaysian population. - Some of the metrics are blocked by yourconsent settings
Publication Storage Optimization For Digital Quran Using Sparse Matrix With Hexadecimal Representation(Univ Utari Malaysia-Uum, 2017) ;Al Omoush, A ;Norwawi, NM ;Ismail, R ;Wahid, FAMazlan, AADigital Quran is a common application today in smart devices such as hand phones and tablet. The verses are usually presented using images of verses on written in an Arabic font. This raise issues related to storage when representing the whole Quran text. This study proposed a hexadecimal digital representation technique for words in Arabic using UTF-8 for character encoding which is backward compatible with ASCII code. This paper will explain three approaches used in representing the digital Quran. They are the hexadecimal representation for each Quranic words, sparse matrix in representing verses of Al-Quran and double offset indexing for transforming the sparse matrix to efficiently use the space. This representation proof more than 50% reduction in the memory space for storage thus will increase the searching speed. The storage of words being optimized through the use of one memory space for that particular word rather than one memory space for each Arabic character in the words. This technique helps optimized memory management for the whole digital Quran. Due to the smaller size, the digital Quran can be conveniently installed in the future as standard applications in mobile devices.
