Research ArticleOpen accessEvery word in the titleEnhancing SQL Injection Detection: A Machine Learning Approach Using Network Flow DataP. Vinoth, K. Muthamil Sudar, S. MuthukumarBackground: SQL injection is one of the cyberattacks which occurs in web application vulnerabilities. It targets the poor input validation and enables the attackers to inject malicious queries into the database fields in any application. It will grant access to unauthorized users and data modification, or they will take control over the complete database. To prevent this, there are several … …Journal of Computer Science, Vol. 22, Issue 8 · 18 Aug 2026 · 1,051 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTransverse Velocity, Transverse Boundary Shear Stress and Flow Deviation in Meandering Open ChannelsYoussef Ismail HafezThis study presents a novel approach for characterizing the mechanics of flow in mildly meandering open channels, specifically focusing on the development of a new vertical distribution equation for transverse velocity. Unlike existing equations in the literature that rely on complex logarithmic or integral forms or infinite series forms, which are impractical for hydraulic engineers, the proposed equation employs ordinary … …American Journal of Environmental Sciences, Vol. 20, Issue 1 · 25 Jul 2024 · 5,058 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnalysis of Non-Equilibrium Phase Change in Transfers at Low Water Content by Considering the Film FlowMarcel Bawindsom Kébré, François Ouédraogo, Bétaboalé Naon et al.In this study, we analyze the effect of non-equilibrium phase change on transfer at low water content in a sandy soil by considering the contribution of film flow in the motion of liquid water. Indeed, most of the non-equilibrium study methods use for hydraulic conductivity, the van Genuchten-Mualem (VGM) capillary model which does not consider the film flow occurred at … …American Journal of Environmental Sciences, Vol. 17, Issue 1 · 1 Jun 2021 · 6,395 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSolving the Robust Design Problem for a Two-Commodity Flow Network with Node FailureNoha Hamdy Radwan, Moatamad Refaat Hassan, Mohamed Eid HusseinThe robust design in a flow network is one of the most important problems. It is defined as searching the optimal capacity that can be assigned to the nodes such that the network still survived even under the node’s failure. This problem is considered NP-hard. So, this study presents a genetic-based algorithm to determine the maximum node capacity for a … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 28 Dec 2020 · 6,593 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleQuickest Multi-Commodity Flow Over Time with Partial Lane ReversalsTanka Nath Dhamala, Shiva Prakash Gupta, Durga Prasad Khanal, Urmila PyakurelRouting of more than one different commodity from specific origin nodes to the corresponding destination nodes through the arcs of an underlying network respecting the capacity constraints is one of the main problems in operational research. Among them, the quickest multi-commodity flow problem concerns with minimization of time taken to complete this process. The general multi-commodity and quickest multi-commodity flow … …Journal of Mathematics and Statistics, Vol. 16, Issue 1 · 2 Oct 2020 · 7,307 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLexicographically Maximum Dynamic Flow with Vertex CapacitiesPhanindra Prasad Bhandari, Shree Ram Khadka, Stefan Ruzika, Luca E. SchäferWe consider an evacuation planning problem in the sense of computing a feasible dynamic flow lexicographically maximizing the amount of flow entering a set of terminals with respect to a given prioritization and given vertex capacities. We propose a polynomial time algorithm for the static version of the problem and a pseudo-polynomial time algorithm for the dynamic case. We show … …Journal of Mathematics and Statistics, Vol. 16, Issue 1 · 24 Jul 2020 · 6,693 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHeat Generation/Absorption Effect on Natural Convection Flow in a Vertical Annulus with Time-Periodic Boundary ConditionsMichael O. Oni, Basant K. JhaThe role of heat generation/absorption on natural convection flow formation in a vertical annulus with prescribed time-periodic heating is investigated in this article. The governing continuity, momentum and energy equations are converted into ordinary differential equation using suitable transformations and closed form expressions are obtained for temperature distribution, velocity profile, Nusselt number, skin friction and mass flow rate in terms … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 27 Jul 2019 · 6,335 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA New Approach to Load Flow Analysis for Radial Distribution System - Application for Medium Voltage Distribution System in MoroccoSaad Ouali, Abdeljabbar CherkaouiThis paper presents a load flow algorithm based on the backward/forward sweep principle, flexible for radial distribution system reconfiguration, with an improvement in ensuring a minimum number of searching for connections between nodes in the calculation sequence in the forward and the backward sweep, by organizing the radial distribution system information into a Main-Line and its derivations. The proposed load … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 29 Jun 2019 · 8,393 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Deploying the Flow Guide Vane in Upstream of Triangular Duckbill Weirs on the Efficiency of this Type of Weir in Laboratory ConditionsSayedeh Zahra Hosseini-Teshnizi, Manuchehr Heidarpour, Saeid Eslamian et al.One of the effective ways for the flow of water in low head water conditions is using triangular duckbill weirs. Regarding the high efficiency of these weirs in higher rate of flow discharge in constant head water conditions, the investigation about this type of weirs is greatly required. The present study is done on triangular duckbill weir with two different … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 27 Jun 2019 · 7,199 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDesign and Testing of Screw Turbines for Flat Flow with Uneven Blade DistancesYulianto, Bambang Priyadi, Fathoni, Hari SuciptoIt is an innovative thing to design turbines that are compatible with flat-flow water energy. The turbine that was chosen is a turbine screw model with a non-uniform blade slope. The turbine made with a stator consists of a collector pipe and a quick pipe as a nozzle and a screw-shaped rotor with varying blade spacing.
