Research ArticleOpen accessIn the abstractMechanical Strength and Durability Properties of High Performance Mortar Containing Densified Silica FumeCheah Chee Ban, Mahyuddin RamliProblem statement: Numerous data and information on pozzolanic reaction and microfiller properties of silica fume were derived from laboratory investigation on silica fume in undensified form. Currently, due to low bulk density of undensified silica fume which poses problem in transportation and handling of the material, silica fume are commercially supplied in densified form. Densification process used to increase bulk … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,958 accessesView PDFCite
Research ArticleOpen accessIn the abstractComposition-Explicit Distillation Curves of Waste Lubricant Oils and Resourced Crude Oil: A Diagnostic for Re-Refining and EvaluationLisa Starkey Ott, Beverly L. Smith, Thomas J. BrunoProblem statement: We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications include a composition-explicit data channel for each distillate fraction and temperature measurements that are true thermodynamic state points that can be modeled with an equation of state. The composition-explicit information is achieved with a sampling approach that allows precise qualitative … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 8,106 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Computer Aided Diagnosis System for Lung Cancer Detection\Using Support Vector MachineM. Gomathi, P. ThangarajProblem statement: Computer Tomography (CT) has been considered as the most sensitive imaging technique for early detection of lung cancer. Approach: On the other hand, there is a requirement for automated methodology to make use of large amount of data obtained CT images. Computer Aided Diagnosis (CAD) can be used efficiently for early detection of Lung Cancer. Results: The usage … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 8,290 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Modeling and Characterization of Thin Film, Narrow Gap Sensor Array Units (SAU)Mahmoud Z. IskandaraniDesign, modeling, testing and analysis multi-gap PbPc sensor array units for the purpose of gas detection are carried out. The tested devices showed reduction in conductance as a function of increasing gap width and reducing film thickness and an increase as a function of temperature up to 160°C. An observed morphological change in the sublimed film is realized at 190°C … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 6,859 accessesView PDFCite
Research ArticleOpen accessIn the abstractWaste Generation and Recycling: Comparison of Conventional and Industrialized Building SystemsRawshan Ara Begum, Siti Khadijah Satari, Joy Jacqueline PereiraProblem statement: In the Malaysian construction industry, there is a pressing issue of minimizing construction waste, which cause significant impacts on the environment. With the increasing demand for major infrastructure projects, commercial buildings and housing development programmers, a large amount of construction waste is being produced. Adoption of prefabrication and industrialized building systems is now a priority in the industry … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 9,939 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Integrated Model for the Versioning of Image ObjectsS. KhaddajProblem statement: The efficient management and retrieval of the enormous volumes of information generated by many imaging applications is still a challenging problem. Approach: In this study we are particularly interested with the use of object oriented techniques for the management of digital images. Indeed, it is widely accepted that the use of data abstraction in object oriented modeling enables … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jul 2010 · 6,914 accessesView PDFCite
Research ArticleOpen accessIn the abstractSensitivity of Fish Landings to Some Meteorological Parameters: A Case StudyMadihah Jafar-Sidik, Than Aung, Awnesh SinghProblem statement: A widely held belief that climate change has impacts on sustainable fish catch leads us to find out how these effects influence fish landings in Sabah, Malaysia, especially for the west and east coasts, based upon monsoonal periods. Correlation of fish landings with rainfall suggests that local fish landing is believed to be sensitive to the effects of … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,440 accessesView PDFCite
Research ArticleOpen accessIn the abstractNodes Density and Broadcast Management in Heterogeneous Environments of Mobile Ad-Hoc NetworksEssam Natsheh, Khalid BuraggaProblem statement: The research presented in this study looks into Mobile Ad-Hoc Networks (MANETs) environment that has varying node densities, called heterogeneous density environment. Such environment can be roughly associated with situations varying from areas struck by disasters to normal city environments. Approach: This study improved the performance of existing MANETs routing protocols by reducing the communication overhead incurred during … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 7,332 accessesView PDFCite
Research ArticleOpen accessIn the abstractEconomic Efficiency Analysis for Information Technology in Developing CountriesGhassan F. Issa, Shakir M. Hussain, Hussein Al-BahadiliProblem statement: The introduction of Information Technology (IT) to government institutions in developing countries bears a great deal of risk of failure. The lack of qualified personnel, lack of financial support and the lack of planning and proper justification are just few of the causes of projects failure. Study presented in this study focused on the justification issue of IT … …Journal of Computer Science, Vol. 5, Issue 10 · 30 Oct 2009 · 6,904 accessesView PDFCite
Research ArticleOpen accessIn the abstractWomen Empowerment through Participation in Micro-Credit Programme: A Case Study from BangladeshMahmuda Hoque, Yoshihito ItoharaProblem statement: Numerous micro-credit organizations have been emerged as the form of mushroom in Bangladesh in the recent times.
