    Abstract Increasing global energy consumption has become an urgent problem as natural energy sources such as oil, gas, and uranium are rapidly running out. Research into renewable energy sources such as solar energy is being pursued to counter this. Solar energy is one of the most promising renewable energy sources, as it has the potential to meet the world’s energy needs indefinitely. This study aims to develop and evaluate artificial intelligence (AI) models for predicting hourly global irradiation. The hyperparameters were optimized using the Broyden-Fletcher-Goldfarb-Shanno (BFGS) quasi-Newton training algorithm and STATISTICA software. Data from two stations… More >

    Libo Xie1, Xue Wang1, Luxiang Liu2,*, Chunmei Xu1, Yongdun Xie2, Hongchun Xiong2, Xinchun Han3, Mu Guo1

    Phyton-International Journal of Experimental Botany, Vol.92, No.11, pp. 2947-2964, 2023, DOI:10.32604/phyton.2023.042919 - 24 October 2023

    Abstract Hot pepper (Capsicum annuum L.) is consumed as one of the oldest domesticated crops all over the world. Although mutation breeding using radiation has been performed in hot peppers, little is known about the comparative analysis of mutagenic effects at the molecular level by ion beam irradiation. To comprehend the response mechanism of hot pepper to the ion beam, we used a mutant with favorable economic characteristics induced by lithium-ion beam irradiation to investigate the biological effects. The results indicated that the lithium-ion beam had a positive effect on important agronomic traits, particularly yield unit, but… More >

    Abstract Background: Phototherapies based on sunlight, infrared, ultraviolet, visible, and laser-based treatments present advantages like high curative effects, small invasion, and negligible adverse reactions in cancer treatment. We aimed to explore the potential therapeutic effects of blue light emitting diode (LED) in human hepatoma cells and decipher the underlying cellular and molecular mechanisms. Methods: Wound healing and transwell assays were employed to probe the inhibition of the invasion and migration of hepatocellular carcinoma cells in the presence of blue LED. The sphere-forming test was used to evaluate the effect of LED blue light irradiation on cancer… More > Graphic Abstract

    Bi-LSTM-Based Deep Stacked Sequence-to-Sequence Autoencoder for Forecasting Solar Irradiation and Wind Speed

    Neelam Mughees1,2, Mujtaba Hussain Jaffery1, Abdullah Mughees3, Anam Mughees4, Krzysztof Ejsmont5,*

    CMC-Computers, Materials & Continua, Vol.75, No.3, pp. 6375-6393, 2023, DOI:10.32604/cmc.2023.038564 - 29 April 2023

    Abstract Wind and solar energy are two popular forms of renewable energy used in microgrids and facilitating the transition towards net-zero carbon emissions by 2050. However, they are exceedingly unpredictable since they rely highly on weather and atmospheric conditions. In microgrids, smart energy management systems, such as integrated demand response programs, are permanently established on a step-ahead basis, which means that accurate forecasting of wind speed and solar irradiance intervals is becoming increasingly crucial to the optimal operation and planning of microgrids. With this in mind, a novel “bidirectional long short-term memory network” (Bi-LSTM)-based, deep stacked,… More >

    A. BELOUADAH1, S. BERDOUS1,3, D. BERDOUS2, M. IZERROUKEN4, N. SAIDI-AMROUN1

    Journal of Polymer Materials, Vol.39, No.1-2, pp. 1-15, 2022, DOI:10.32381/JPM.2022.39.1-2.1

    Abstract In this work, neutron induced structural modifications, on the biaxially-oriented polyethylene naphthalate (BOPEN) film, were studied by X-ray diffraction technique (XRD), Fourier transform infrared spectroscopy (FTIR/ATR), scanning electron microscopy (SEM) and polarized light optical microscopy (PLOM). The irradiation with neutron was carried out, under air, at room temperature. The changes of the structure, in volume and in surface were evaluated under the impact of neutron’s flux composed by thermally neutrons and fast neutrons. The X-ray technique showed the effect of the neutron flux’s fluence on the crystallinity of the BOPEN, which was also determined through More >

    KRIGING SURROGATE BASED OPTIMIZATION OF THERMAL DAMAGE TO LIVING BIOLOGICAL TISSUES BY LASER IRRADIATION BASED ON A GENERALIZED DUAL PHASE LAG MODEL

    Nazia Afrina,*, Jonathan Lopez, Juan Ocampo

    Frontiers in Heat and Mass Transfer, Vol.18, pp. 1-7, 2022, DOI:10.5098/hmt.18.46

    Abstract Large number of numerical computer simulations in engineering places is a serious burden on associated optimization problems nowadays. Kriging Surrogate based optimization (KSBO) becomes standard practice in analyzing expensive and time-consuming simulation. This paper aims to investigate the surrogate based analyze and optimization of thermal damage in living biological tissue by laser irradiation using a generalized duel phase model. The relationships of maximum temperature and thermal damage in living biological tissues of the response with two variables at a time are studied. The result shows that the surrogate model predicted response variables i.e, temperature and More >

    Dehong Teng1,#, Jing Zhang1,#, Xinzhi Luo1, Fei Jing1, Hengwei Wang1, Jing Chen1,* , Chao Yang1, Shaohong Zang1,*, Yingtang Zhou1,2

    Journal of Renewable Materials, Vol.10, No.9, pp. 2378-2391, 2022, DOI:10.32604/jrm.2022.019209 - 30 May 2022

    Abstract Semiconductor photocatalysis is a novel highly efficient and low-cost method for removing organic pollutants from wastewater. However, the photoreduction performance of semiconductors on organic pollutants is limited due to the weak absorption of visible light caused by its wide band gap and low carrier utilization rate resulting from severe electron-holes recombination. In the present study, flower-like NH2-UiO-66 (NU66)/ZnO nanocomposites were prepared using a facile method and exhibited high efficiency under visible light driven photocatalysts. The X-ray diffractometer (XRD), scanning electron microscope (SEM), transmitor electron microscope (TEM), and X-ray photoelectron spectroscopy (XPS) were used to characterize… More > Graphic Abstract

    Abstract In order to achieve a highly accurate estimation of solar energy resource potential, a novel hybrid ensemble-learning approach, hybridizing Advanced Squirrel-Search Optimization Algorithm (ASSOA) and support vector regression, is utilized to estimate the hourly tilted solar irradiation for selected arid regions in Algeria. Long-term measured meteorological data, including mean-air temperature, relative humidity, wind speed, alongside global horizontal irradiation and extra-terrestrial horizontal irradiance, were obtained for the two cities of Tamanrasset-and-Adrar for two years. Five computational algorithms were considered and analyzed for the suitability of estimation. Further two new algorithms, namely Average Ensemble and Ensemble using… More >

    Abstract Solar energy has gained attention in the past two decades, since it is an effective renewable energy source that causes no harm to the environment. Solar Irradiation Prediction (SIP) is essential to plan, schedule, and manage photovoltaic power plants and grid-based power generation systems. Numerous models have been proposed for SIP in the literature while such studies demand huge volumes of weather data about the target location for a lengthy period of time. In this scenario, commonly available Artificial Intelligence (AI) technique can be trained over past values of irradiance as well as weather-related parameters… More >

    Journal of Renewable Materials, Vol.9, No.6, pp. 1075-1085, 2021, DOI:10.32604/jrm.2021.014555 - 11 March 2021

    Abstract In our previous study, silver nanoparticles were prepared using AgNO3 and carboxymethyl chitosan (CMCS) which is commercially available with solar irradiation. In this study, the efficacy and safety of silver nanoparticles prepared by this method were evaluated for healing wounds in rats with diabetes. We also attempted to determine the underlying mechanism and influencing factors of the silver nanomaterial preparation method. Compared with growth factors, silver nanoparticles exhibit better healing effects for rats with diabetes. No remnant silver ions were detected in the major organs of these rats after the application of silver nanoparticles. Silver nanoparticles… More >
