Maximum power point tracking (MPPT) represents one of the significant challenges for designing photovoltaic (PV) systems. Thus, an effective MPPT method solar panels is required to make them more efficient. Here, four intelligent methods have been applied MPPT. Fuzzy logic (FL) has used without knowledge expert create membership functions and rules. Also, artificial neural network (ANN) employed based on three meta-heuristic algorithms, including genetic algorithm (GA), particle swarm...
This study investigated the adsorption capacity of Remazol Black B (RBB) from aqueous solutions using a pumice stone as cheap, high-frequent, and available adsorbent. The raw was modified five acids: Acetic, Sulfuric, Phosphoric, Nitric, Hydrochloric acid. Fourier transform infrared spectrograph (FTIR), x-ray fluorescence (XRF), scanning electron microscopy (SEM) were used to analyze morphological chemical properties adsorbents. equilibrium Langmuir, Freundlich, Temkin, Dubinin -...
<i>Planck<i/> is a scientific satellite that represents the next milestone in space-based research related to cosmic microwave background, and many other astrophysical fields. was launched on 14 May of 2009 now operational. The uncertainty optical response its detectors key factor allowing achieve objectives. More than decade analysis measurements have gone into achieving required performances. In this paper, we describe main aspects optics are relevant science, estimated in-flight...
Thin layer drying characteristics of high moisture corn under fixed, semi fluidized and bed conditions with initial content (66.82% wb) in a laboratory convective dryer was studied at air temperatures 50, 65, 80 95°C. In order to find suitable curve, seven thin layer-drying models were fitted the experimental data ratio. Among applied mathematical models, Midilli et al. model best for behavior prediction drying. This presented values correlation coefficient (R2). Fick´s second law used...
We identify five rice cultivars by mean of developing an image processing algorithm. After preprocessing operations, 36 colour features in RGB, HSI, HSV spaces were extracted from the images. These used as inputs back propagation neural network. The feature selection operations performed using STEPDISC analysis method. classification accuracy with for paddy, brown and white acquired 93.3, 98.8, 100%, respectively. to classify paddy cultivars, 13 selected this study. highest (96.66%) was...
Nowadays, the use of laser scanner devices as an active technique for acquiring 3D information is growing fast. The huge amount object points produced with less effort than other acquisition techniques one reasons interest. For accurate measurements a sophisticated sensor model and calibration procedure important prerequisite such efficient system. accuracy assessments measurement system reflect reliability correctness output. we laser’s intensity image model, which developed by extending...
Abstract This work investigates important heat and mass transfer parameters of a variety paddy named Fajr, during thin layer convective drying. The experiments on drying are conducted at air temperatures in the domain 30–80°C with velocities between 0.54 3.27 m s −1 . Mathematical equations developed to adjust experimental data obtained for results show that Henderson Pabis' model satisfactorily fit all behavior paddy. effective diffusivity moisture transfer, calculated by Fick's second law...
The Planck mission of the European Space Agency (ESA) is designed to image anisotropies Cosmic Background Radiation Field over whole sky. Planck's objective analyze, with highest accuracy ever achieved, remnants radiation that filled universe immediately after Big Bang, which we observe today as cosmic microwave background. To achieve this aim well-manufactured reflectors are used parts telescope receiving system. system consists Secondary and Primary Reflectors sections two different...
Abstract In the present study, we performed a simultaneous optimization of various inlet temperatures, vacuum pressures, and maltodextrin concentrations to produce chicory root inulin extract powder by novel approach ongoing ultrasonic spray drying. To obtain optimum conditions, used central composite face‐centered design response surface methodology (RSM). Performing this drying in vacuumed chamber required lower temperatures compared conventional dryers. We 4–6% (wt/vol) at 50, 65, 80 °C...
Traditional methods of separating defective cucumbers are inherently labor‐intensive and time‐consuming. However, with the emergence intelligent farming practices, deep learning (DL) algorithms, particularly in fields image processing machine vision, have demonstrated significant potential to address this challenge. The main objective research study is develop a DL‐based algorithm capable classifying into three distinct categorical groups based on their visual characteristics: defective,...
Identification of rice cultivars is very important in modern agriculture. Texture properties could be used to identify among the various factors. The digital images processing can as a new approach extract texture features. objective this research was using features with image and back propagation artificial neural networks. To cultivars, five Fajr, Shiroodi, Neda, Tarom mahalli Khazar were selected. Finally, 108 textural extracted from gray level co-occurrence matrix. Then cultivar...
