Research ArticleOpen accessIn the abstractAn Intrusion Detection Framework for MEC-Enabled IoT NetworksRofaida Tawfik, Abdelfattah Hegazy, Hesham Dahshan, Ahmed Gaber AbuabdallahMobile Edge Computing (MEC) has emerged as a promising paradigm for supporting latency-sensitive Internet of Things (IoT) applications by bringing computational resources closer to data sources. However, the distributed nature of MEC environments increases exposure to network-based security threats, particularly network intrusions that can impact both system reliability and task offloading efficiency. This paper proposes a security-aware framework that integrates … …Journal of Computer Science, Vol. 22, Issue 4 · 1 Apr 2026 · 1,921 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Approach of Satellite Image Enhancement Using DWT Based on 2-Type Fuzzy LogicSurjeet Singh Patel, Vivek Kumar Tamta, Abhilekh Bartwal et al.This study proposes a new approach to enhance the dark and low-contrast satellite images captured under poor illumination. Images are converted from RGB to HSV color space in order to separate the Hue (H), Saturation (S), and luminance (V) components. Enhancement is achieved in saturation and luminance components using Discrete Wavelet Transform (DWT) and 2-type fuzzy logic. DWT breaks the … …Journal of Computer Science, Vol. 19, Issue 9 · 15 Aug 2023 · 5,182 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulti-Level Image Thresholding via Nonlinear Fitting of the HistogramSalah AmeerThis paper proposes a novel scheme for multi-level image thresholding. The 1D cumulative histogram is curve-fitted to a polynomial of nonlinear basis function, the hyperbolic tangent (tanh). The thresholds are the positions of the minima of the first (odd) derivative of the fitting polynomial, since the histogram is the derivative of the cumulative histogram. The tanh function is considered as … …American Journal of Applied Sciences, Vol. 16, Issue 12 · 28 Dec 2019 · 7,533 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Practical and Secure Hash Function-Based Password Authentication SchemeMuhammad Helmi Ali, Eddie Shahril Ismail, Firdaus Mohamad HamzahIn this study, we propose a practical and secure hash function-based password authentication scheme using smart cards. Our proposed scheme offers some advantages and interesting features. Firstly, the scheme does not require a verification table and is secure against the replay attacks, an attack that most of the existing schemes suffer. Secondly, any user of the scheme be allowed to … …Journal of Computer Science, Vol. 15, Issue 7 · 17 Jul 2019 · 7,738 accessesView PDFCite
Research ArticleOpen accessIn the abstractModification on PPS Sample Scheme with ReplacementAyed R.A. Alanzi, Naser A. Alodat, Ahmad M. QazzaIn this paper we have developed an alternative estimator for the Probability Proportional to Size (PPS) with replacement sampling scheme when certain characteristics under study are positively correlated with the selection probability. An analogue to the well-known superpopulation model for finite population is also suggested, using which, we compare the proposed estimator with Hansen and Hurwitz estimator. Finally, an empirical … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 19 Jun 2019 · 7,188 accessesView PDFCite
Research ArticleOpen accessIn the abstractNovel Scheme for Enhancing Storage Management and Performance and Saving Energy of Mobile Cloud ComputingAli A. Yassin, Abdulla J. Yassin, Abdullah Mohammed Rashid, Ahmed A. AlkadhmaweeModern industries for smart mobile devices, such as smartphones, provide end users with interactive features that consider network accessibility, computation performance, storage usage, energy saving and limited battery resources. The combination of cloud and mobile computing capabilities has introduced a new technology called Mobile Cloud Computing (MCC), which has extended smartphones and modern mobile devices beyond their core capacities. Many … …Journal of Computer Science, Vol. 15, Issue 5 · 9 May 2019 · 7,871 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproved 3D Imaging Performance of AFMMd Sohel RanaOver the last three decades the Atomic Force Microscopy (AFM) has played an important role in the field of nanotechnology for imaging and manipulating samples. However, the acquisition of a high-quality imaging performance by an AFM is significantly influenced by its key scanning element called its Piezoelectric Tube Actuator (PTA). In this article, to improve its performance, a multi-input multi-output … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 28 Jan 2020 · 7,295 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Improvement of SNP Search Using Multithread ProgrammingGeraldo Francisco Donegá Zafalon, Álvaro Magri Nogueira da Cruz, Anderson Rici Amorim et al.Pattern recognition is an important field in Bioinformatics and a well-known task is the search for Single Nucleotide Polymorphism (SNP). It is possible to search for a known SNP position and analyze it using patterns of DNA bases, called masks. Nonetheless, this process becomes computationally expensive as the amount of available genomic data increases. Thus, in this study, we have … …Journal of Computer Science, Vol. 14, Issue 11 · 7 Nov 2018 · 7,734 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Security of the Sensor Cloud Security Library (SCSlib)Mohamed Rasslan, Mahmoud Nasreldin, Ghada Elkabbany, Aya ElshobakyNowadays, cloud computing has experienced remarkable growth. Indeed, one of the main challenges of cloud computing is to protect data from different sensor devices during processing and storing. In 2014, Henze et al. proposed the Sensor Cloud Security library (SCSlib) which allows cloud developer to access encrypted sensor data stored in the cloud. SCSLib drawback is that it allows a … …Journal of Computer Science, Vol. 14, Issue 6 · 23 May 2018 · 8,072 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review of the Recent Advances Made in the Black-Scholes Models and Respective Solutions MethodsYasir Hamad Al Saedi, Gurudeo Anand TularamThe Black-Scholes model has been a major advance in finance over a period of time; this paper examines this model in some detail, in terms of the latest developments in both analytical and numerical solutions. The paper initially briefly examines historical aspects but quickly moves to a critical analysis of the works in the applications, solutions and implications for the … …Journal of Mathematics and Statistics, Vol. 14, Issue 1 · 8 Jan 2018 · 8,621 accessesView PDFCite
