Research ArticleOpen accessIn the abstractDeveloping an Integrated Method for Optimal Design of Chilled Water Plants in HVAC SystemsNabil Nassif, Nihal Al Raees, Fouad Al Rifaie, Taher Abu-LebdehBuildings account for a large portion of energy use in the US. Many those buildings have equipped with central plants to produce chilled water supplied to central air handling units. The chilled water plant design can have a significant impact on building energy uses and costs. In this paper, an integrated method for optimal design of chilled water plants is … …Energy Research Journal, Vol. 9, Issue 1 · 6 Feb 2019 · 6,592 accessesView PDF Cite

Research ArticleOpen accessIn the abstractVariable Neighborhood Simplex Search Methods for Global Optimization ModelsPongchanun LuangpaiboonProblem statement: Many optimization problems of practical interest are encountered in various fields of chemical, engineering and management sciences. They are computationally intractable. Therefore, a practical algorithm for solving such problems is to employ approximation algorithms that can find nearly optimums within a reasonable amount of computational time. Approach: In this study the hybrid methods combining the Variable Neighborhood Search … …Journal of Computer Science, Vol. 8, Issue 4 · 15 Feb 2012 · 6,517 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Rigorous Mathematical Approach for Petrophysical Properties EstimationDario VibertiProblem statement: Over the last few decades, the oil industry has shown a growing interest in the new risk analysis methodologies aimed at the evaluation of the uncertainties associated with reservoir exploitation. In particular, the effort is made to take all possible sources of uncertainties into account so that not only the strengths but also the potential weaknesses of each … …American Journal of Applied Sciences, Vol. 7, Issue 11 · 8 Nov 2010 · 7,981 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptimal Power Multicast Problem in Wireless Mesh Networks by Using a Hybrid Particle Swarm OptimizationAllam Maalla, Chen Wei, Haitham J. TahaProblem statement: Most mobile nodes in a wireless ad hoc network are powered by energy limited batteries; the limited battery lifetime imposes a constraint on the network performance. Therefore, power consumption of network operations is critical and subject to optimization. Approach: A novel hybrid PSO was proposed for solving the minimum power multicast problem in wireless ad-hoc networks. The MPM … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 6,814 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordOptimized Wireless Sensor Network Clustering Using a Hybrid Firefly–Bat Algorithm (HFBA)J. Jegan, Senthil kumar P, S. Saravanakumar et al.Wireless Sensor Networks (WSNs) are composed of numerous sensor nodes that collaborate to observe and evaluate various environmental parameters, transmitting the data to a central base station. Each node is equipped with a unique transmitter, receiver, and processor to facilitate sensing, processing, and communication. These networks are often installed in extremely remote and inaccessible areas. A significant challenge arises from … …Journal of Computer Science, Vol. 22, Issue 5 · 19 May 2026 · 1,441 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordOptimization of Food Expenditures in Nigeria: A Case Study of Lafia, Nasarawa StateOlusola Collins Akeremale, Imam Akeyede, Ishaku Audu, Adekemi O. AkeremaleCurrently, the prices of commodities in Nigeria are consistently rising owing to several variables, including economic conditions, political influences, and technical progress. Consequently, the cost of essential items, including food, has risen significantly. Consequently, they often disregard nutritious dietary habits and fail to obtain adequate daily nutrients. This will lead to several repercussions, including diseases, disorders, and less vitality for … …American Journal of Applied Sciences, Vol. 22, Issue 1 · 12 Feb 2026 · 2,536 accessesView PDF Cite
