Research ArticleOpen accessIn the abstractA Method for Transmitting Spacecrafts in Space with Velocity of at Least 0.01 of the Light Speed Using Materials with Very High Kinetic Energy in High Electric FieldsMario Nady AiadMany space new missions are on calendar this decade for Moon, Mars and other planets. Some of these missions are depending on simple reliable chemical thrusters and others on the nonchemical advanced propulsion techniques. In most of nonchemical techniques a nuclear source of energy is necessary as in nuclear electric rockets where the maximum velocity produced is around 20 km/s. … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 4 · 22 Dec 2023 · 5,371 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimized Earthquake Evacuation Routes Using Dijkstra's Algorithm and WinQSBSandra Huarcaya Gonzales, Hugo Vega-Huerta, Gisella Luisa Elena Maquen-Niño et al.This research analyzes and generates optimal evacuation routes in the Barranco district during earthquake scenarios using the Dijkstra algorithm implemented through WinQSB. A preliminary review was conducted to establish key concepts related to earthquake dynamics, evacuation route planning, and the application of Dijkstra’s algorithm. Given its high seismic exposure and the prevalence of aging infrastructure, Barranco is considered highly vulnerable … …Journal of Computer Science, Vol. 21, Issue 10 · 9 Dec 2025 · 2,858 accessesView PDFCite
Research ArticleOpen accessIn the abstractSFAD2H: Selective Forwarding or Dropping Attack Detection with 2-Hop Acknowledgment Support in Wireless Sensor NetworksPrathap Uppara, Kiran Krishnappa, Deepa Shenoy Punjalkatte, Venugopal Kuppanna RajukSecurity in wireless sensor networks is critical due to its way of open communication. In this study we have proposed a technique based on a sensor node having alternate path knowledge and 2-hop acknowledgement mechanism to detect adversary nodes which perform selective forwarding and dropping attacks. In selective forwarding attack nodes on the forwarding path refuses to transfer packets selectively. … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 23 Nov 2017 · 7,463 accessesView PDFCite
Research ArticleOpen accessIn the abstractHands-On Fire Extinguisher Training Apparatuses: Expert Evaluations of Two Propane Fire Simulators and Air-Pressurized Water ExtinguishersAwwad Dababneh, Abdul Jaleel Hamad Majeed, Rami H. FouadTwenty-two expert firefighting professionals were used in evaluating four methods for fire extinguisher hands-on training. Two different fire simulators were put into service along with two conditions for the fighting distance; keeping a distance of 2.44 m (8ft.) away from the base of the fire and having no restriction on getting closer to the fire. The fire simulators both utilized … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 3 · 27 Jul 2017 · 7,663 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparison between Different Data Mining Algorithms in Freight Mode ChoiceAmir Samimi, Hesamoddin Razi-Ardakani, Amir NohekhanThis research aims to study application of support vector machine algorithm, artificial neural networks and five different types of decision trees in predicting mode choice of freight transportation. Performance of these models has been compared with log it model which is one the most prevalent statistical models in the field. Effect of factors such as cargo weight, distance, type and … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 5 Feb 2017 · 7,626 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Proposed Design for Illumination and Cameras Surveillance System for Optimum Supervision at a Perimeter Area of Nuclear FacilityAmir Abdel Wadoud, Alaa Abdelwahab SalehAn important component of a comprehensive security plan is lighting. Security Protective Lighting has three functional objectives: To illuminate a person, object, place or condition of security to permit observation and identification, to be a physical deterrent through the glare effect of direct light on the human eye and to be a psychological deterrent creating in an intruder's mind the … …American Journal of Applied Sciences, Vol. 15, Issue 1 · 3 Feb 2018 · 8,056 accessesView PDFCite
Research ArticleOpen accessIn the abstractData Clustering using Two-Stage Eagle Strategy Based on Slime Mould AlgorithmRachid Oucheikh, Achraf Touil, Mouhsene FriDataclustering is considered an important component of data mining which aims tosplit a given dataset into disjoint groups having the same similarities. Thedeveloped techniques for clustering have some challenges to cluster entities incomplex search space and most of them aim to maximize the sum of inter-clusterdistances and minimize the sum of intra-cluster distances. This objectivefunction is nonlinear and hard to … …Journal of Computer Science, Vol. 18, Issue 11 · 7 Nov 2022 · 5,795 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Components of Data Governance Framework for MOOC Providers in IndonesiaYakob Utama Chandra, Harjanto Prabowo et al.The COVID-19 pandemic had a universal and synchronous impact on all countries globally, leading to the implementation of the social distancing policy that mandated all activities take place within one's own house. One of the implementations is distance education. Since the pandemic, e-learning, which is the dominant use of information technology in the education sector, has gained widespread recognition and … …Journal of Computer Science, Vol. 20, Issue 12 · 31 Oct 2024 · 4,777 accessesView PDFCite
Research ArticleOpen accessIn the abstractPredictive Mathematical Modeling and Classification of Retail Sales Orders Using AI Machine Learning TechniquesMohammad Subhi Al-Batah, Mowafaq Salem Alzboon, Hamzeh ZureigatThis study presents a systematic mathematical model known as a low-code approach to classifying retail sales orders by size using AI machine learning techniques within the Orange Data Mining platform. Leveraging a real-world sales dataset sourced from Kaggle, we implemented and evaluated ten classification models, including ensemble learners (AdaBoost, Gradient Boosting), probabilistic classifiers (Naïve Bayes), distance-based methods (kNN), and interpretable … …Journal of Computer Science, Vol. 22, Issue 3 · 10 Mar 2026 · 1,573 accessesView PDFCite
Research ArticleOpen accessIn the abstractRobust Adversarial Attack Detection via Generative Adversarial Network With Residual Multi-Layer Aggregation Based Contrastive Loss FunctionAmudha Gopalakrishnan, Nalini JosephAdversarial attacks in medical imaging refer to subtle modifications to images that mislead diagnostic systems, resulting in inaccurate diagnoses and assessments. These attacks exploit vulnerabilities in image processing, leading to misclassification or altered visual features that often go unnoticed. This raises serious concerns about the security and reliability of medical diagnosis, directly impacting clinical decision-making and patient safety. This research … …Journal of Computer Science, Vol. 22, Issue 1 · 10 Feb 2026 · 1,749 accessesView PDFCite
