Research ArticleOpen accessIn the abstractPerformance Analysis of Threshold Based Compressive Sensing Algorithm in Wireless Sensor NetworkParnasree Chakraborty, C. ThariniWireless Sensor Networks (WSN) are comprised of spatially distributed sensor nodes, where each node contains sensors, processors and transceivers for communicating data. Regardless of the application in which the sensor network is serving, the data generated in the network eventually must be delivered to the sink. However the limited network bandwidth, frequent node/link failure along with the unreliable communication medium … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 3 Feb 2017 · 7,512 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Design and Construction of a Dual Axis Solar Tracker Prototype for a Dish Concentrator using ATMega3298P MicrocontrollerAlbright Abu Edet, Samaila Umaru, Isah IbrahimThe desire for reliable power supply is the reason for further research into alternative sources of power. Although solar tracking is not a new technology, yet solar harvesters still suffer low efficiency due to the intermittence of solar insolation. Thus many smart systems have been designed to maximise solar harvesters. Among the systems is the dual axis solar tracking system. … …Journal of Mechatronics and Robotics, Vol. 5, Issue 1 · 21 Apr 2021 · 7,253 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiosynthesis and Evaluation of Zinc, Copper, and Methionine Feed Supplements Using Saccharomyces cerevisiae on Duck Performance in Minimal Water SystemsHendi Setiyatwan, Muhammad Rifqi IsmirajOptimizing duck performance under minimal water conditions is essential for sustainable poultry farming. Biosynthesizing essential feed supplements like Zinc (Zn), Copper (Cu), and methionine using Saccharomyces cerevisiae presents a promising method to enhance growth and meat quality. This study developed a biosynthesis method for Zn, Cu, and methionine supplements using S. cerevisiae and evaluated their effects on duck performance. In … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 1 · 11 Feb 2025 · 4,409 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Firefly-Inspired Scheme for Energy-Efficient Transmission Scheduling Using a Self-Organizing Method in a Wireless Sensor NetworksZeyad Ghaleb Al-Mekhlafi, Zurina Mohd Hanapi, Mohamed Othman, Zuriati Ahmad ZukarnainVarious types of natural phenomena are regarded as primary sources of information for artificial occurrences that involve spontaneous synchronization. Among the artificial occurrences that mimic natural phenomena are Wireless Sensor Networks (WSNs) and the Pulse Coupled Oscillator (PCO), which utilizes firefly synchronization for attracting mating partners. However, the PCO model was not appropriate for wireless sensor networks because sensor nodes … …Journal of Computer Science, Vol. 12, Issue 10 · 11 Dec 2016 · 7,715 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Study on Energy Efficient in Traveling Wave Pulse Coupled Oscillator for Wireless Sensor NetworksZeyad Ghaleb Al-Mekhlafi, Zurina Mohd Hanapi, Mohamed Othman, Zuriati Ahmad ZukarnainWSNs are unable to afford simultaneous transmission and reception of data and for most scenarios, the battery replacement is impossible upon the exhaustion of a node's battery energy. Thus, energy efficient protocols constitute vital design requirements for the WSN as a whole in order to increase the lifetime and ensure successful transmission of data from sensor node source to target, … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 21 Nov 2016 · 7,358 accessesView PDFCite

This research will focus on the development of the high performance boost power converter to power up any laptop or notebook and design power management system of … …American Journal of Applied Sciences, Vol. 13, Issue 9 · 11 Sep 2016 · 7,642 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign Maximum Power Point Tracking (MPPT) on Photovoltaic Panels using Fuzzy Logic MethodAhmad Faizal, Sutoyo, Mulyono et al.Solar energy is a clean energy, renewable, and available for the long term. The tool used to convert the energy generated from the intensity of sunlight into electricity is photovoltaic panels. However, due to the high cost and low efficiency, the use of the energy is still kind small compared to other types of energy sources. Thus, the need for … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 10 Aug 2016 · 8,503 accessesView PDFCite
Review ArticleOpen accessIn the abstractReview of Charge Pump Topologies for Micro Energy Harvesting SystemsMichelle Lim Sern Mi, Md. Shabiul Islam, Jahariah Sampe, Sawal Hamid Md. AliThis paper reviews CMOS based charge pump topologies used within autonomous embedded micro-systems. These charge pump structures have evolved from its simplistic diode-tied, single-branches with major threshold drops to exponential type, dual-branches with sophisticated gate and substrate control for lower voltage operation. Published charge pumps are grouped based on architecture, operation principles and pump optimization techniques with their pros and … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 26 May 2016 · 7,630 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasuring Intra-City Eco-Efficiency Variations of Urban Infrastructures in JeddahMohammed Aljoufie, Alok TiwariSaudi cities are experiencing construction booms linked to urban infrastructure services and the Kingdom’s second largest city, Jeddah, is not an exception.
