In this regard, a wide range of solutions has been made available by in-troducing deep learning-based classification systems for different staple crops. Despite being one of the most important commercial crops in many parts of the globe, research proposing a smart solution for automatically classifying apple leaf diseases remains relatively unexplored. This work proposes a transfer learning-based approach for identifying apple leaf diseases. The system extracts features using a pretrained EfficientNetV2S architecture and passes to a classifier block for effective prediction. The class imbalance issues are tackled by utilizing runtime data augmentation. The effect of various hyperparameters, such as input resolution, learning rate, number of epochs, etc., has been investigated carefully. The competence of the proposed pipeline has been evaluated on the apple leaf disease subset from the publicly available ‘PlantVillage’ dataset, where it achieved an accuracy of 99.21 %, outperforming the existing works.","PeriodicalId":131537,"journal":{"name":"2023 International Conference on Electrical, Computer and Communication Engineering (ECCE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131564786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main objectives of this study were to identify the most suitable transport layers to use and to figure out the optimal perovskite thickness for higher absorption and efficient transport properties. In this study, the performance of perovskite-based solar cells for three different electron transport materials (ETM) layers—ZnO, TiO2, and SnO2 was evaluated using the Solar Cell Capacitance Simulator (SCAPS)-1D. In the suggested configuration, nickel oxide (NiOx) was chosen as the hole transport material (HTM), mixed halide perovskite (CH3NH3PbI3) as the absorber material, and zinc oxide (ZnO), TiO2, and SnO2 as the ETM. Our analysis revealed that Jsc, FF, Voc, and efficiency are all significantly influenced by the type and thickness of the absorber layer in a perovskite solar cell. Perovskite layers containing defects were considered for conducting the analysis. The results demonstrate that by varying the layer thickness, the efficiency of the power conversion may be enhanced. When the thickness is increased PCE increases immediately but it decreases after a period of time. When ETM layer is ZnO, the findings demonstrate a considerable improvement in efficiency (18%).","PeriodicalId":131537,"journal":{"name":"2023 International Conference on Electrical, Computer and Communication Engineering (ECCE)","volume":"159 1-4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132846009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the year different mechanisms have been applied for controlling the active front end rectifier. In our paper, the rectifier has been designed and controlled without the need of PI controller. The model's robustness is analyzed by evaluating total harmonic distortion (THD), switching frequency and voltage deviation for various system conditions. The chosen method performs in a discrete periods and requires no external modulators. By applying dynamic references, it shows flexibility in power control. Real power source and voltage references are also provided without using extra control loop. Variation of total harmonic distortion, switching frequency and voltage has been analyzed and the system has been designed and investigated in MATLAB Simulink. Simulation findings indicate a faster and more appropriate determination of reactive power and dynamic voltage. The proposed method also have been analyzed for different load types to validate its efficacy.

This study proposes a time-frequency (T-F) masking-based speech enhancement approach which resembles the human auditory peripheral subsystem using the ratio of clean and noisy signal magnitudes using a U-Net model. The proposed work is carried out in several seen and unseen noisy conditions with several SNR values. To assess the performance of the proposed enhancement approach, speech intelligibility, and quality scores using four objective scores have been evaluated.

In order to maintain and grow a micro-grid economically, optimization is essential. A variety of equality and inequality requirements may be met to reduce the entire production cost, which includes subsidies for things like capital, operations, pollution, and renewable energy. Grey wolf optimization (GWO) is a powerful and adaptable cost-cutting strategy. GWO is used in tandem with other AI-based optimization methods in particular situations. Here, we provide a model for evaluating the viability, expense, and societal and environmental effects of energy systems that operate independently from the grid. Harmonization of micro-grids. It's possible that the micro-mathematical grid's role is to recycle power output hour by hour in accordance with available resources and to store any excess energy in a battery. In this work, we simulate and optimize a PV-Wind-WtE-battery hybrid system in the halishahar thana of Chattogram, Bangladesh. Design concerns include renewable energy sources including solar panels, wind turbines, batteries, and diesel engines. By our estimates, the thana uses around 107,150 MWh of power annually. We use a Grey wolf optimization approach to find the optimal design parameters to minimize the overall yearly cost. This micro-grid can easily provide 1,40,423.8 MWh, more than enough to power Halishahar for a whole year. A low levelized cost of energy (LCOE) of 0.221 $kWh is achieved with this setup. It reduces carbon dioxide emissions by a larger margin than traditional power.","PeriodicalId":131537,"journal":{"name":"2023 International Conference on Electrical, Computer and Communication Engineering (ECCE)","volume":"369 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124630304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An energy management system (EMS) is used to integrate these resources cost-effectively. The intermittent nature of Solar energy, however, might have an impact on the energy security and stability of power systems. To guarantee the effectiveness, dependability, and quality of electricity provided, an optimal control approach is crucial. In this research, a Heuristic and Optimization-based EMS is developed to deliver energy from available resources. The supply system of the microgrid consists of Solar PV, and Energy Storage Systems (ESS) in addition to the main utility grid to serve the residential loads through smart EMS with optimal cost. Inside the Heuristic EMS logical decisions like - when to utilize the main grid or, cut it down are made based on the accessibility of Solar PV and battery state-of-charge (SoC). While, an optimization objective function is formulated within the EMS, aiming at reducing grid intake, utilizing off-peak hours for charging ESS from the grid, maximizing renewable penetration, and potentially exploiting these on-site generators during on-peak hours. Manipulating some practical datasets two plausible cases have been studied to test and validate the performance of the proposed model. Finally, the simulation outcomes of the two methods are compared with each other. As the electricity price significantly changes, the optimization-based EMS was found effective to manage the battery charge-discharge operation and can minimize the residential electricity bill consequently.","PeriodicalId":131537,"journal":{"name":"2023 International Conference on Electrical, Computer and Communication Engineering (ECCE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128392199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
