Research ArticleOpen accessIn the abstractEvaluation of Environmental and Hydraulic Performance of Bio-Composite Revetment BlocksThamer A. Mohamed, Nor A. Alias, Abdul H. Ghazali, Mohd. S. JaafarIt is necessary to develop a concrete revetment block which can cater for environment and at the same time it will be effective in protecting river banks (stabilize the slope of banks) from scouring during flood. In the present study, the environmental and hydraulic performance of the proposed revetment block was evaluated through laboratory and field tests. The tested revetment … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 6,967 accessesView PDF Cite

Research ArticleOpen accessIn the abstractContributions on Laser Driven Inertial Confinement FusionHeinrich HoraThe following modified preprint of a chapter in the forthcoming book by Guillermo Velarde and Natividad Carpintero Santamaria Inertial Confinement Nuclear Fusion: A Historical Approach by its Pioneers with personal comments is presented here as an example about the long years difficult developments towards the aim for producing unlimited, safe and clean nuclear energy in the same way as it … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 7,106 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCase Study on the Effects of Plan Irregularities on Seismic Performance of StructuresEduardo Flores, Tadeh ZirakianGeometric configurations, such as large openings, re-entrant corners, and discontinuity in diaphragms, are very common in architectural design but are seen as undesirable for structural performance during earthquakes. The lateral systems in a structure resist the strong forces induced during an earthquake, preventing damage or collapse of the structure. If these systems fail, the structural integrity of the building may … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 21 Jul 2024 · 5,723 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnalysis and Synthesis of Mechanisms with Bars and Gears Used in Robots and ManipulatorsRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.Bars and gears are used everywhere today, but a wide range of uses is robotics and mechatronics. Since ancient times, automations and mechanization have been used with mechanisms consisting of chains of bars and gears. These were obviously used for the purpose of transmitting the movement and its transformation, that is to say, as a mechanical transmission. Gear and bar … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 20 Dec 2017 · 7,052 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIndoor Environmental Comfort in Malaysian Urban HousingYaik-Wah LimIn Malaysia, terraced houses have been rapidly constructed since 50 years ago and account for 44% of the existing urban housings. However, these houses have very limited use of natural ventilation and daylighting due to openings with small window-to-floor ratio. The deep plan design causes gloomy indoor spaces, low air change rate and poor indoor air quality. Studies showed that … …American Journal of Environmental Sciences, Vol. 9, Issue 5 · 22 Nov 2013 · 7,467 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOPTIMIZATION MODEL OF SELECTIVE CUTTING FOR TIMBER HARVEST PLANNING BASED ON A SIMULATED ANNEALING APPROACHMunaisyah Abdullah, Salwani Abdullah, Abdul Razak Hamdan, Roslan IsmailAn optimization model for Timber Harvest Planning (THP) is used to form harvest areas with the objective of maximizing the tree harvest volume subject to harvest regulations. Most optimization models for THP currently in use are based on clear cutting and restricted to adjacency constraints to prevent the creation of large clear-cut openings in the forest. However, an optimization model … …Journal of Computer Science, Vol. 10, Issue 1 · 12 Nov 2013 · 7,313 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNatural Ventilation of Indoor Air Temperature: A Case Study of the Traditional Malay House in PenangAhmad Sanusi Hassan, Mahyuddin RamliProblem statement: It was the aim of the study to analyze the level of performance of natural air ventilation with a case study of the traditional Malay house in Penang, Malaysia. This study provided information on the architectural design in relation to natural air ventilation. It promoted passive design in contrast to most housing design which has poor natural air … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 3 · 30 Sep 2010 · 11,956 accessesView PDF Cite
