Research ArticleOpen accessEvery word in the titleResearch of Effect of Peculiarities of Creasing a Polymer Sheet Material on a Rigid Base on Parameters of a Folding OperationIl'dus Zakirov, Yuriy Kataev, Alexandr Nikitin, Nargiz FaizullinaFolded elements are widespread in design of various products. They are made of sheet metal, cardboard, plastics or other materials. For example, heat exchangers, printed products, cardboard or plastic folders, folded fillers for three- or multilayered panels, which are made of paper, cardboard or plastics material can be mentioned. Although folded fillers are significantly advanced in terms of structural or … …American Journal of Applied Sciences, Vol. 14, Issue 10 · 20 Aug 2017 · 7,542 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Best Candidates Method for Solving Optimization ProblemsHlayel Abdallah AhmadProblem statement: This study is about describing solution technique called Best Candidates Method (BCM) for solving optimization problems; the goal is to minimize the computation time to get the optimal solution. In this study I apply the BCM to the linear assignment problems (LAP) that is one of the optimization problems in the Operation Research (OR). Approach: The optimization problem … …Journal of Computer Science, Vol. 8, Issue 5 · 27 Feb 2012 · 8,341 accessesView PDFCite
Research ArticleOpen accessIn the keywordsConstrained Response Surface Optimization for a Laser Beam Welding ProcessPongchanun LuangpaiboonProblem statement: On a current operating condition of a laser beam welding process in the hard disk drive industry, it has been found that shear strength of the head support and suspension assembly is slightly higher than customers' specification. This situation leads to an inspection with a large sample size and a high frequency. Shear strength is not only one … …Journal of Mathematics and Statistics, Vol. 7, Issue 1 · 29 Jan 2011 · 7,368 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInventory Management Systems with Hazardous Items of Two-Parameter Exponential DistributionAzizul Baten, Anton Abdulbasah KamilProblem statement: An exponentially decaying inventory was first developed by[10]. The certain commodities were observed to shrink with time by a proportion which can be approximated by a negative exponential function of time. Here, the novelty we took into consideration was that a constant hazardous rate followed by the two-parameter exponential distribution. Approach: We studied the inventory system with two-parameter … …Journal of Social Sciences, Vol. 5, Issue 3 · 30 Sep 2009 · 8,297 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Mechanical Properties of Sweet Potato Seedlings on Quality of Mechanized Processing and Recycling WorkJunming Liu, Tao Zhang, Jian Sun et al.To research and understand the mechanical properties of sweet potato seedlings, and to provide relevant data for the development of machinery related to sweet potato seedlings processing and recycling, this paper used Shangshu 19 sweet potato seedlings in harvesting period as the test material, the shear test and moisture content of sweet potato seedlings were tested, the influence of moisture … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 22 May 2025 · 6,619 accessesView PDFCite
Research ArticleOpen accessIn the abstractIrregular Reflexive Labeling and Elementary Row Operations for Enhanced Biometric Image EncryptionIka Hesti Agustin, Dafik et al.A total k-labeling defined the function fe: E(G) → {1, 2, …, ke} and fv: V(G) → {0, 2, …, 2kv}, where, k = max {ke, 2kv}. For graph G, the total k-labeling is called an edge (or a vertex) irregular reflexive k-labeling if the condition of every two different edges (or vertices) has different weights. The smallest value of … …Journal of Computer Science, Vol. 20, Issue 12 · 20 Nov 2024 · 4,149 accessesView PDFCite

Research ArticleOpen accessIn the abstractA Vision System Based on Time-of-Flight and RGB Cameras Applied to Robotic Tree Peony Fruit HarvestingJiaming Liu, Dong Zhao, Tianxing Li, Jian ZhaoTree peony is a deciduous shrub endemic to China and the Peony Seed Oil (PSO) is an important plant oil resource. However, at present, fruits harvesting of peony are mainly completed by manual work with low efficiency. In response to the need for a mechanized operation, a multi-sources vision system based on Time-Of-Flight (TOF) and RGB cameras was set up … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 19 Aug 2020 · 6,329 accessesView PDFCite
Review ArticleOpen accessIn the abstractBeyond Survival: The Unique Salt Secretion and Ion Homeostasis Mechanisms in Limonium bicolor Under Salt StressLinyang Wang, Pin Chen, Shuge TianSoil salinization poses a significant threat to global agriculture. Limonium bicolor, a recretohalophyte, has evolved a unique and efficient salt tolerance mechanism centered on epidermal salt glands for secreting excess salts. This review systematically synthesizes the multilevel salt tolerance strategies in Limonium bicolor, covering the structural basis of its multicellular salt glands, the molecular regulatory networks governing their development including … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 8 Sep 2026 · 791 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Implementation of a Smart File Cabinet System With Enhanced Security and Remote AccessAdebayo Afeez Oluwagbenga, Mustapha Favour, Adebiyi Temidayo Daniel et al.In an era increasingly defined by digital interconnectivity, the physical security of sensitive hard-copy documents remains a persistent vulnerability in organizational infrastructure. Traditional filing cabinets, relying on passive mechanical locks, lack the capability for real-time monitoring, remote access control, or active intrusion detection. This research presents the design and validation of a Smart File Cabinet (SFC) system that bridges this … …Journal of Mechatronics and Robotics, Vol. 10, Issue 1 · 25 May 2026 · 1,696 accessesView PDFCite
