Research ArticleOpen accessEvery word in the titleIntelligent Traffic Light System Using Convolutional Neural Network to Optimize Vehicle Flow in IndonesiaBhustomy Hakim, Fergie Joanda Kaunang, Yemima Monica Geasela, Regina HillaryTraffic congestion remains a persistent challenge in major Indonesian cities due to rapidly increasing vehicle density and the continued reliance on fixed-time traffic signal scheduling. This study aims to develop an intelligent traffic light system that dynamically adjusts sequencing based on real-time road conditions. A dataset of 902 CCTV images was collected from intersections in six large cities across Indonesia, … …Journal of Computer Science, Vol. 22, Issue 2 · 17 Feb 2026 · 2,155 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSentiment Analysis Using Light Weight - Gradient Boosting Machine based Feature SelectionBikku Ramavath, Srikanth Kadainti, Nemani SubashSentiment analysis is a significant task in Natural Language Processing (NLP) that differentiates the emotions and opinions expressed in text or reviews. The sentiment analysis is challenging due to the complex language patterns and inappropriate or redundant features used for classification. In this research, the Light Weight - Gradient Boosting Machine (LWGBM) based feature selection is proposed to choose relevant … …Journal of Computer Science, Vol. 21, Issue 5 · 26 May 2025 · 4,695 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImpact of Lighting Durations on Production, Quality, and Fungal Contamination in Green FodderSuci Wulandari, Adib Norma Respati, Satria Budi Kusuma et al.This study aimed to identify hydroponic fodder seeds with optimal production and chemical quality and to determine the fungal species contaminating the green fodder produced. This study used a 2´5 Factorial Completely Randomized Design pattern, with 2 replications. Factor I consisted of two lighting treatments: (1) 12 hours of natural sunlight and (2)24 h of light (natural sunlight followed by … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 3 Jun 2025 · 4,792 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Assumption Regarding the way Matter is Constituted and Structured from LightFlorian Ion Tiberiu PetrescuThe paper briefly presents some basic ideas on how matter is constituted and structured, based on permanent light as intrinsic energy. The fact that photons cannot be stored directly inside matter has not prevented it from having multiple hearts of energy springing from light, in the form of positive and negative electrical charges, which form the energy base of matter … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 2 · 8 Jun 2022 · 6,271 accessesView PDFCite

Review ArticleOpen accessEvery word in the titleStructural Colour from Optical Phenomena Caused by Interference with a Thin or Multilayer Film, Photonic Nanocrystals, Light Scattering and Diffraction Grating EffectRelly Victoria Petrescu, Raffaella Aversa, Antonio ApicellaThe paper presents the Ion Plating Plasma Assisted technology that is applied in the area of surface functionalization with the purpose of preserving the structural colour and relics. The interferometric structural colours applied on titanium surfaces were used and tested together with nano-transparent and at the same time achromatic films on the very old ceramic artifact. In order to test … …Journal of Aircraft and Spacecraft Technology, Vol. 4, Issue 1 · 13 Aug 2020 · 6,503 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBlue and White LED Lights Enhance Biosynthesis of Rosmarinic Acid in Cell Culture of Agastache rugosaWoo Tae Park, Sun Kyung Yeo, Nam Su Kim et al.Agastache rugosa, an herbaceous Korean perennial, contains pharmacologically important phenylpropanoids such as tilianin and rosmarinic acid. However, the knowledge of biosynthesis of phenylpropanoids from A. rugosa is limited. Therefore, a study was conducted to develop an efficient protocol for in vitro regeneration of A. rugosa and to investigate the influence of three different LED light wavelengths (white, blue and red) … …OnLine Journal of Biological Sciences, Vol. 20, Issue 2 · 24 May 2020 · 6,860 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleEffects of Visible and Near Infrared Polarized Lights on Spoofing Face DetectionAzim Zaliha Abd AzizFace spoofing countermeasure is vital to avoid an imposter from gaining access to security biometric systems by using face masks in various forms that mimic a valid user face. Recently, several studies have shown the ability of visible polarized light in distinguishing real and fake faces. In this paper, polarization imaging systems using visible and near infrared (NIR) are proposed … …Journal of Computer Science, Vol. 15, Issue 2 · 23 Feb 2019 · 7,893 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAbout the Light DimensionsFlorian Ion T. Petrescu, John Kaiser CalautitLight is one of the most fascinating something of all the time. This paper aims to develop a tool with which one can determine with great accuracy the dimensions of light. Basically was entered a new relationship through which one may determine the size of a photon depending on the wavelength of light. Instead wavelength of light can be used … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 28 Mar 2016 · 10,611 accessesView PDFCite
