Research ArticleOpen accessEvery word in the titleIdentification of Erosion Hotspot Area using GIS and MCE Technique for Koga Watershed in the Upper Blue Nile Basin, EthiopiaTewodros T. Assefa, Manoj K. Jha, Seifu A Tilahun et al.Soil erosion is a serious threat in Ethiopian highlands. Continuous land degradation resulted in loss of fertile top soil leading to low agricultural productivity. In addition, excessive soil erosion from Koga Watershed in upper catchment to an artificial reservoir (Koga Dam reservoir) is substantially reducing its service life. Community participatory based effective watershed management strategies may have tremendous potential to … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 10 Sep 2015 · 9,147 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleClassification Model for Hotspot Occurrences Using Spatial Decision Tree AlgorithmImas Sukaesih Sitanggang, Razali Yaakob, Norwati Mustapha, A. N. AinuddinDeveloping a predictive model for forest fires occurrence is an important activity in a fire prevention program. The model describes characteristics of areas where fires occur based on past fires data. It is essential as an early warning system for preventing forest fires, thus major damages because of fires can be avoided. This study describes the application of data mining … …Journal of Computer Science, Vol. 9, Issue 2 · 11 Apr 2013 · 7,224 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOnline Forums Hotspot Prediction Based on Sentiment AnalysisK. Nirmala Devi, V. Murali BhaskarnProblem statement: Online forums hotspot prediction is one of the significant research areas in web mining, which can help people make proper decision in daily life. Online forums, news reports and blogs, are containing large volume of public opinion information. Rapid growth of network arouses much attention on public opinion, it is important to analyse the public opinion in time … …Journal of Computer Science, Vol. 8, Issue 8 · 11 Jul 2012 · 7,360 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSSM: Slot Scheduling Mechanisms in a Multihop Wireless Hotspot NetworkMaan Younis AbdullahOur focus was to determine a "slot" time for message forwarding. To this end, we model the system as a "Queue" where the time for packet forwarding is determined by slot, at different slot range for each relaying node. We also introduced one important reason of the poor performance is the close coupling between medium contention and network congestion. Our … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,445 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCritical Aging Segments of Power Transmission LineH. H. Goh, N. E. Chin, Q. S. Chua et al.Nowadays, blackouts or sags of a conductor are threatening the safety and stable run of the power transmission lines. These phenomena happen due to the environmental conditions which change over the time, such as aging or temperature variations, precipitation and hotspots of power transmission lines as a result of extreme weather conditions. A precipitation condition result loses of heat from … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 9 Dec 2013 · 9,264 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHow to Guide and Assess Risk Reduction using Risk Characterization IndicatorsPeter Borgen Sørensen, Rainer Brüggemann, Marianne Thomsen et al.Problem statement: The risk level predictions in risk assessment often suffer from uncertainties and may, thus, overlook some adverse effects. This problem can be reduced by using risk reduction strategies that continuously guide activities toward lowest possible risk. Approach: This study suggested a method to guide and assess such risk reduction strategies using multi-indicator risk characterization. It was a challenge … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,035 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEnhancing Wireless Medium Access Control Layer Misbehavior Detection System in IEEE 802.11 NetworkA. M. Alsahag, M. OthmanWireless Medium Access Control (MAC) protocols such as IEEE 802.11 use distributed contention resolution mechanisms for sharing the wireless channel. In this environment, selfish hosts that fail to adhere to the MAC protocol may obtain an unfair throughput share. For example, IEEE 802.11 requires hosts competing for access to the channel to wait for a "back-off" interval, randomly selected from … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,963 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Bibliometric Assessment of Urban Agriculture Indexed in Scopus and Wos From 1978-2023Emrobowansan Monday Idamokoro, Augustine Suh Niba, Eunice Amaka AkuruUrban agriculture is a system of food production in and around urban settlements aimed at ameliorating the challenge of food shortage. The goal of this study is to explore emergent worldwide publication trends, contemporary focus and gaps in urban agriculture research over the last four decades (1978-2023). Despite the numerous research work on urban agriculture, gap existed in literatures on … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 14 Sep 2025 · 3,978 accessesView PDFCite
Research ArticleOpen accessIn the abstractProducing Functional Fatty Acid DHA from Corn Steep Liquor by Aurantiochytrium SW1Xiaojie Ren, Qi Yan, Baoyue Liu et al.Thraustochytrium has a relatively high lipid content in the cell and its lipid content can account up to 70% of the dry cell weight. It is an important raw material for the third-generation biodiesel production and the production of functional fatty acid Docosahexaenoic Acid (DHA). However, the high cost of traditional fermentation medium has hindered the industrial production of lipid. … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 4 · 20 Nov 2021 · 6,323 accessesView PDFCite
