Research ArticleOpen accessIn the keywordsLeveling Process of Total Electron Content (TEC) Using Malaysian Global Positioning System (GPS) DataY. Norsuzila, M. Abdullah, M. IsmailThe signals from the satellites of the Navstar Global Positioning System (GPS) travel through the earth's ionosphere on their way to GPS receivers. However, ionospheric delay is one of the main sources of error in GPS. The magnitude of the ionospheric delay is influenced by the Total Electron Content (TEC) along the radio wave path from a GPS satellite to … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 7,768 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Improved Handwritten Tamil Character Recognition System using Octal GraphR. J. Kannan, R. PrabhakarProblem Statement: Handwriting recognition has attracted voluminous research in recent times. The segmentation and recognition of the characters from handwritten scripts incorporates considerable overhead. Almost all the existing handwritten character recognition techniques use neural network approach, which requires lot of preprocessing and hence accomplishing these problems using neural network is a tedious task. Approach: In this study we propose a … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 7,408 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNew Role of Sulfuric Acid In Production of Multicomponent Fertilizers From Renewable SourcesHelena Górecka, Henryk Górecki, Katarzyna Chojnacka et al.The paper discusses the possibility of using renewable sources: slaughter wastes and wood ashes in the production of NPK fertilizers. The content of macronutrients, micronutrients and toxic elements in these materials was reported. In the present work, poultry feathers were used as fertilizer source of nitrogen, animal bones as the source of phosphorus and wood ash as the source of … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 8,378 accessesView PDFCite
Review ArticleOpen accessIn the keywordsBio-Inspired Materials: Exhibited Characteristics and Integration Degree in Bio-Printing OperationsAntreas KantarosIn the last decade, additive manufacturing techniques, commonly known under the term "3d printing" have seen constantly increasing use in various scientific fields. The nature of these fabrication techniques that operate under a layer-by-layer material deposition principle features several de facto advantages, compared to traditional manufacturing techniques. These advantages range from the precise attribution of pre-designed complex shapes to the … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 4 · 29 Nov 2022 · 7,185 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Effect of Early Weaning on Performance, Health Parameters, and Carcass Traits of Bonsmara Bull Calves Under Feedlot ConditionsKgotso Patrick Matli, Thobela Louis Tyasi, Pieter FourieA feedlot is an intensive farming system used for finishing livestock. This study analyzed the performance, health, and carcass traits of Early-Weaned Calves (EWC) and Traditionally-Weaned Calves (TWC). A total of 285 Bonsmara bull calves were grouped into two weaning strategies, with 136 EWC (255±27.30 kg) and 149 TWC (308±24.60 kg). Backgrounding was followed by a finishing phase, with a … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 2 · 14 Aug 2026 · 1,239 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImpacts Evaluation of DoS Attacks Over IPv6 Neighbor Discovery ProtocolAmjed Sid Ahmed, Rosilah Hassan, Nor Effendy Othman et al.The Neighbor Discovery Protocol (NDP) is one of the main protocols in the Internet Protocol version 6 (IPv6) suite. It provides many basic functions for the normal operations of IPv6 in a Local Area Network (LAN), such as address auto-configuration and address resolution. However, NDP has several vulnerabilities that can be used by malicious nodes to launch attacks, because NDP … …Journal of Computer Science, Vol. 15, Issue 5 · 29 May 2019 · 8,333 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Successive Admissible Cell Method for Solving Large Scale Linear Assignment Problem with Dense Cost MatrixWarut Boonphakdee, Peerayuth CharnsethikulNormally, the Linear Assignment Problem (LAP) has been solved by successful algorithms such as Lapjv and Munkres programmed as MATLAB codes. This study presented an improved algorithm for solving large scale LAP. A preprocessing (PP) algorithm was proposed to apply for constructing the kth transferred reduced cost matrix then this matrix was solved by Lapjvalgorithm. Performances of PP-Lapjvalgorithm were faster … …Journal of Computer Science, Vol. 12, Issue 8 · 16 Nov 2016 · 6,951 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCreating New Spaces for Learning: Fostering Experiential and Service Learning, Journeys through the African American PastDolapo Adeniji-NeillProblem statement: Experiential education and service learning are interchangeable. They are defined as an approach to education that implicitly trusts the learner’s ability to learn through experience, rather than a movement for change that seeks to challenge mainstream education. While literature, research, communities and schools recognize the importnce of experiential education, controversies exit as to their efficacies in learning processes. … …Journal of Social Sciences, Vol. 8, Issue 2 · 25 Feb 2012 · 9,094 accessesView PDFCite
Research ArticleOpen accessIn the author namesImage Pre-Processing Techniques to Improve DBT Classification Accuracy With CNN ResNet-50Qodri Aziz, Slamet Riyadi et al.Digital Breast Tomosynthesis (DBT) is a three-dimensional imaging technology that is meant to determine breast cancer more accurately than regular mammograms. But low contrast and noise can make DBT images less clear, which can make deep learning-based classification less accurate. This study seeks to assess the impact of diverse preprocessing techniques on breast cancer classification outcomes utilizing the ResNet-50 Convolutional … …Journal of Computer Science, Vol. 22, Issue 10 · 21 Oct 2026 · 419 accessesView PDFCite
