Research ArticleOpen accessIn the abstractControl Strategy for Discontinuous Conduction Mode Boost Rectifier with Low Total Harmonic Distortion and Improved Dynamic ResponseH.S. AthabDue to its simplicity, the discontinuous conduction mode boost rectifier is potentially the least expensive active line-harmonics reducing circuit. Problem statement: The line current however, shows considerable distortion when the peak input voltage is close to the output voltage, As a result, the input power factor is poor. This study proposes a simple, low-cost method to reduce the line harmonics. … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,418 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Distance Based Route Maintenance Strategy for Dynamic Source Routing ProtocolMuhammad F. Sjaugi, Mohamed Othman, Mohd. Fadlee A. RasidAlthough DSR can respond a route quickly, it yields a long delay when a route is rebuilt. This is because when source node receives RERR packet, it will try to find alternative routes from the route cache. If alternative routes are not available, the source node, then, will enter route discovery phase to find new routes. We introduced a new … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 8,314 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison Between Biological Treatment and Chemical Precipitation for Nitrogen Removal from Old Landfill LeachateLong Tengrui, Anas F. Al-Harbawi, He Qiang, Zhai JunThe study reports the results of a laboratory scale investigation aimed at evaluating the effectiveness of mature municipal landfill leachate treatment by a biological stage (used SBBR as a biological treatment) and Chemical precipitation (Used MAP precipitation (magnesium ammonium phosphate)) to study the nitrogen removal capabilities for treatment of sanitary landfill leachate containing high ammonia concentration, and the comparison between … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 7,032 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacteristics of Nitrogen Removal from Old Landfill Leachate by Sequencing Batch Biofilm ReactorLong Tengrui, Anas F. Al-Harbawi, Lin Ming Bo et al.Municipal landfill leachate is a high strength wastewater characterized by high concentrations of organics and ammonia and potentially containing toxic materials. The paper reports the results of a laboratory scale investigation aimed at evaluating the effectiveness of mature municipal landfill leachate treatment by a biological stage (used SBBR as a biological treatment) to study the nitrogen removal capabilities for treatment … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 8,039 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Harmonic Components on Transformer Losses of Sinusoidal Source Supplying Non-Linear LoadsI. Daut, H. S. Syafruddin, Rosnazri Ali et al.An important consideration when evaluating the impact of harmonics is their effect on power system component and loads. Transformers are major components in power systems. The increased losses due to harmonic distortion can cause excessive losses and hence abnormal temperature rise. The measurement of iron losses and copper losses of single-phase transformers is important in particular for transformers feeding nonlinear … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 8,398 accessesView PDFCite
Research ArticleOpen accessIn the abstractDC Motor Control Predictive ModelsRavinesh Singh, Godfrey C. Onwubolu, Krishnileshwar Singh, Ritnesh RamDC motor speed and position controls are fundamental in vehicles in general and robotics in particular. This study presents a mathematical model for correlating the interactions of some DC motor control parameters such as duty cycle, terminal voltage, frequency and load on some responses such as output current, voltage and speed by means of response surface methodology. For this exercise, … …American Journal of Applied Sciences, Vol. 3, Issue 11 · 30 Nov 2006 · 7,015 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesigning Omni-Directional Mobile Robot with Mecanum WheelJefri Efendi Mohd Salih, Mohamed Rizon, Sazali Yaacob et al.This study presents the processes undertaken in the design and development of an intelligent omni-directional mobile robot using four custom-made mecanum wheels. The mecanum wheel developed consists of nine rollers made from delrin. All mecanum wheels are independently powered using four units of precisian gear DC motors and the wheel/motor assemblies were mounted directly to the robot chassis made using … …American Journal of Applied Sciences, Vol. 3, Issue 5 · 31 May 2006 · 9,593 accessesView PDFCite

Research ArticleOpen accessIn the abstractBridging Traditional Craftsmanship and Digital Interaction through User-Centered Design: Designing Intuitive InterfacesChristopher Kevin Gunawan, Ravi Ardiza Putra, Steven Albert et al.Traditional craftsmanship served as both a manifestation of cultural heritage and a vital pillar of the global creative economy. However, its digital integration was frequently hindered by low technological literacy and misalignment between manual practices and standardized digital systems. Existing digital interventions primarily focused on passive e-commerce storefronts and often ignored the socio-economic precarity of craftsmen operating as independent contractors … …Journal of Computer Science, Vol. 22, Issue 6 · 5 Jun 2026 · 1,551 accessesView PDFCite
