Research ArticleOpen accessIn the abstractImproving Response Time of Authorization Process of Credit Card System Using Multi-Threading and Shared-Memory Pool TechniquesSiti H.A. Hamid, Mohd H.N.M. Nasir, Wong Y. Ming, Hazrina HassanCurrent credit card authorization was developed on single-threaded model whereby authentication process takes longer time to respond due to sequential process of card's risk management profile and its limitation of handling huge number of simultaneous transactions at single point of time. As a result, the performance of the authorization system was affected during peak hours. This study presented an architectural … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 7,236 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Slope Assessment Systems for Predicting Landslides of Cut Slopes in Granitic and Meta-sediment FormationsSuhaimi Jamaludin, Bujang B.K. Huat, Husaini OmarIn Malaysia, slope assessment systems (SAS) are widely used in assessing the instability of slope or the probability of occurrence and the likely severity of landslides. These SAS can be derived based on either one particular approach or combination of several approaches of landslide assessments and prediction. This study overviews four slope assessment systems (SAS) developed in Malaysia for predicting … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 6,909 accessesView PDFCite
Research ArticleOpen accessIn the abstractMigration from Relational Database into Object Oriented DatabaseMansaf Alam, Siri Krishan WasanObject-Oriented Technology is an important discipline in the field of software engineering in general and it is, therefore, natural to ask whether it is relevant to the field of database management in particular and what that relevance is. There is, however, no consensus on answer to these questions. Some authorities believe that object oriented database systems will take over the … …Journal of Computer Science, Vol. 2, Issue 10 · 31 Oct 2006 · 6,447 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Semantic Cache Management Method in Mobile DatabasesShengfei Shi, Jianzhong Li, Chaokun WangIn mobile database systems, caching is a crucial way to improve the performance because a new query can be partially answered locally when the client is continuously moving around. Semantic caching has been paid much attention in traditional database systems. However, the methods of semantic cache management proposed in those systems are not suitable for mobile computing environment. Moreover, although … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,878 accessesView PDFCite
Research ArticleOpen accessIn the abstractReview of Photochemical Smog Pollution in Jakarta Metropolitan, IndonesiaDollaris R. Suhadi, M. Awang, M. N. Hassan et al.An analysis of photochemical smog pollution in Jakarta was attempted using data from the existing air quality monitoring stations. Ground-level ozone potential is high in Jakarta due to the high traffic emissions of ozone precursors and the favorable surface meteorological conditions. Despite the frequent missing data during the 1996-1999 monitoring, which resulted in lower ozone values, ozone episodes were significantly … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 7,247 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Design of MAC Model Based on the Separation of Duties and Data Coloring: DSDC-MACSoon-Book Lee, Yoo-Hwan Kim, Jin-Woo Kim, Chee-Yang SongAmong the access control methods for database security, there is Mandatory Access Control (MAC) model in which the security level is set to both the subject and the object to enhance the security control. Legacy MAC models have focused only on one thing, either confidentiality or integrity. Thus, it can cause collisions between security policies in supporting confidentiality and integrity … …Journal of Computer Science, Vol. 16, Issue 1 · 19 Jan 2020 · 7,459 accessesView PDFCite
