Abstract: One of the most appealing and economical uses of solar energy is drying agricultural goods. With differing degrees of technical performance, a multitude of solar dryer types have been devised and developed across the globe. In general, solar dryers come in four different varieties: (1) direct solar dryers, (2) indirect solar dryers, (3) mixed-mode dryers, and (4) hybrid solar dryers. The product being dried, as well as technical and financial concerns, are reviewed in this paper together with other solar dryer kinds. Technically speaking, integrated storage, high efficiency, compact collector design, and long-life drying systems are the main focuses in the development of solar-assisted drying systems for vegetables. There exist alternative systems to air-based solar collectors. By using a water-to-air heat exchanger, water-based collectors are another option. A water-to-air heat exchanger can be used to push hot air used for drying agricultural products to pass through it. As part of the solar drying system, the hot water tank stores heat

Abstract: Ten years ago, there were barriers to ideal accuracy in many computer vision issues. But the emergence of deep learning techniques brought about a dramatic change that greatly improved the accuracy of these problems. Among these, image classification stands out as a key problem: it is the challenge of accurately classifying images into their corresponding classifications, such dogs and cats. This research aims to improve accuracy by utilizing state-of-the-art object detecting algorithms. In order to tackle this, a great deal of effort has gone into building a convolutional neural network (CNN) that is robust and designed with image categorization in mind. The principal goal is to leverage the capabilities of cutting-edge object identification techniques in order to achieve significant improvements in image classification accuracy.

Abstract: In order to monitor the operating status of vehicles, it is necessary to collect vehicle operating data in real time through IoT devices and analyze these data. However, the collected data has the characteristics of multi-source heterogeneous, network resources are limited and server performance is poor. It is difficult to truly realize data processing in real time. In addition, data needs to be transmitted over the network, it is particularly important to ensure the safety of data transmission. Considering the above problems, it is necessary to structure the data and define a unified data format to facilitate data transmission and analysis. At the same time, improve the server communication program and improve the server's concurrent processing capabilities. In addition, considering that data needs to be transmitted over the network, in order to ensure that the data is not stolen or tampered with, the PRESENT lightweight encryption algorithm is adopted to ensure the safety of data transmission. Compared with encryption algorithms such as AES, this algorithm has much lower hardware requirements. This article combines the characteristics of the project and uses the number of communications between the device and the server to achieve the dynamic key update which is approximately one-time pad, and greatly improves the security of the data.
摘要:为了监控车辆的运行状况,有必要通过物联网设备实时采集车辆运行数据,并对这些数据进行分析。然而,采集到的数据具有多源异构、网络资源有限、服务器性能差等特点。很难真正实现数据的实时处理。此外,数据需要通过网络传输,保证数据传输的安全性尤为重要。考虑到上述问题,有必要对数据进行结构化处理,定义统一的数据格式,方便数据传输和分析。同时,完善服务器通信程序,提高服务器的并发处理能力。此外,考虑到数据需要通过网络传输,为确保数据不被窃取或篡改,采用 PRESENT 轻量级加密算法,确保数据传输的安全性。与 AES 等加密算法相比,该算法对硬件的要求要低得多。本文结合项目特点,利用设备与服务器之间的通信次数,实现了近似一次性pad的动态密钥更新,大大提高了数据的安全性。

Abstract: Advancements in Finite Impulse Response (FIR) filter design have significantly propelled the field of Digital Signal Processing (DSP), addressing the increasing need for high-performance and efficient digital filters. FIR filters are renowned for their stability, linear phase response, and computational efficiency, making them indispensable in applications such as image filtering and frequency modulation. Their inherent advantages, including the ability to leverage Fast Fourier Transformation (FFT) techniques and minimal finite precision arithmetic errors, often make them preferable over Infinite Impulse Response (IIR) filters. Recent research efforts have focused on algorithmic and hardware modifications to optimize FIR filter architectures, employing techniques such as retiming, pipelining, and parallel processing. This paper explores various design techniques and architectures aimed at optimizing FIR filter performance. Additionally, the role of high-speed adder structures, like carry-lookahead adders, is examined for their impact on enhancing digital filter efficiency and the critical role of continuous exploration and optimization in FIR filter design to advance DSP. By addressing the demands of modern technology, these innovations foster the development of high-performance, efficient digital filters, essential for diverse applications and the ongoing progression of digital signal processing.

Abstract: Understanding the intricate interactions between plants, mycorrhizal fungi, and soil health is crucial for sustainable agriculture and climate change mitigation. This review synthesizes current research to elucidate the multifaceted role of plantmycorrhizal-fungal interactions in soil health and carbon sequestration in agroecosystems. A meta-analysis of 75 studies spanning diverse ecosystems and plant species reveals a significant positive correlation between mycorrhizal colonization and soil organic carbon content, with an average increase of 25% compared to non-mycorrhizal systems. Furthermore, mycorrhizal symbiosis enhances soil structure and aggregation, promoting water retention and nutrient cycling, which are essential for maintaining soil fertility and resilience to environmental stressors. The contributions of different mycorrhizal types (arbuscular, ectomycorrhizal, and ericoid) to soil carbon dynamics are also examined, highlighting their unique roles in carbon allocation and stabilization. Additionally, the review discusses the potential implications of plant-mycorrhizal-fungal interactions for mitigating greenhouse gas emissions through enhanced carbon sequestration in agricultural soils. Insights into the mechanisms underlying these interactions, including mycorrhizal-mediated changes in root exudates, microbial communities, and soil enzymatic activities, are discussed. Overall, this review underscores the importance of integrating mycorrhizal symbiosis into agroecosystem management practices to enhance soil health, carbon sequestration, and climate resilience.
摘要:了解植物、菌根真菌和土壤健康之间错综复杂的相互作用对于可持续农业和减缓气候变化至关重要。本综述综合了当前的研究,以阐明植物菌根真菌在土壤健康和农业生态系统固碳中的多方面作用。对跨越不同生态系统和植物物种的 75 项研究进行的荟萃分析表明,菌根定殖与土壤有机碳含量之间存在显著的正相关关系,与非菌根系统相比,平均增加 25%。此外,菌根共生还能增强土壤结构和聚合力,促进水分保持和养分循环,这对保持土壤肥力和抵御环境压力至关重要。综述还研究了不同菌根类型(丛生菌根、外生菌根和麦角菌根)对土壤碳动态的贡献,强调了它们在碳分配和稳定中的独特作用。此外,综述还讨论了植物-菌根-真菌相互作用对通过加强农业土壤固碳来减少温室气体排放的潜在影响。综述还讨论了这些相互作用的内在机制,包括菌根介导的根部渗出物、微生物群落和土壤酶活性的变化。总之,这篇综述强调了将菌根共生融入农业生态系统管理实践以增强土壤健康、碳固存和气候适应能力的重要性。

Abstract: In the context of a lack of fabric in concrete production, particularly in India where rapid infrastructure development has led to increased construction activities, the adoption of environmentally friendly practices is essential. India, renowned for its exceptional cement production worldwide, is now grappling with issues posed by the widespread Covid-19 pandemic, which is significantly disrupting the growth of the construction industry. This has led to neighbouring lockdowns and shortages in texture. The massive amounts of banana waste thrown out in India emit toxic quantities of carbon dioxide and methane gas into the atmosphere. Banana leaf ash may be produced after the bananas have been harvested. One possible use for the agriculture waste known as BANANA LEAF ASH (BLA) is to reduce the amount of cement needed to build concrete. E-GF stands for "ELECTRONIC-GLASS FIBER," which might refer to a material made up of many little glass filaments. In addition to increasing the material's flexural, ductile, and affect properties, these strands fulfil a function similar to the strengthening steel present in traditional reinforced concrete. This Paper talks about maintain the variable frequency to makeup BLA with cement 0%, 2.5%, 5%, 7.5%, 10% & 12.5% & EGF with constant frequency of 3%. Moreover the comparison is held with proxy blends like 0%BLA+0%EGF, 2.5%BLA+3%EGF, 5%BLA+3%EGF, 7.5%BLA+3%EGF, 10%BLA+3%EGF & 12.5%BLA+3%EGF. BANANA LEAF ASH and E-GLASS FIBER together provide a sustainable and strength-enhancing solution for concrete. Seeing how cutting-edge materials may revolutionize building methods is fascinating.
摘要:在混凝土生产缺乏结构的情况下,特别是在基础设施快速发展导致建筑活动增加的印度,采用环保做法至关重要。印度以其卓越的水泥生产而闻名于世,但目前正在努力解决广泛流行的 Covid-19 带来的问题,这极大地扰乱了建筑业的发展。这导致了邻近地区的封锁和质地短缺。印度丢弃的大量香蕉废料会向大气排放有毒的二氧化碳和甲烷气体。香蕉收获后可能会产生香蕉叶灰。被称为香蕉叶灰(BLA)的农业废弃物的一个可能用途是减少建造混凝土所需的水泥用量。E-GF 是 "电子玻璃纤维 "的缩写,指的是一种由许多小玻璃丝组成的材料。除了提高材料的抗弯、延展和抗冲击性能外,这些纤维还具有与传统钢筋混凝土中的强化钢材类似的功能。本文介绍了在使用 0%、2.5%、5%、7.5%、10% 和 12.5% 的水泥和恒定频率为 3% 的 EGF 时,保持可变频率来掺入 BLA。此外,还比较了 0%BLA+0%EGF、2.5%BLA+3%EGF、5%BLA+3%EGF、7.5%BLA+3%EGF、10%BLA+3%EGF 和 12.5%BLA+3%EGF。芭蕉叶灰和 E-GLASS 纤维共同为混凝土提供了一种可持续的强度增强解决方案。尖端材料如何彻底改变建筑方法,令人目不暇接。

Abstract: The occurrence of bacterial, viral, and fungal diseases on rice leaves significantly hampers rice production, posing a challenge to meet global demand for the staple crop. While the detection of rice leaf diseases is crucial, existing methods are constrained by limitations in image backgrounds and capture conditions. Convolutional Neural Network (CNN) models have emerged as a usefull avenue for disease recognition in rice leaves, yet current approaches suffer from decreased recognition rates when applied to independent datasets and are constrained by the need for large-scale network parameters. In this project, we propose an innovative CNN-based model aimed at mitigating these challenges by reducing network parameters. Through training multiple CNN- basedmodels to identify three common rice leaf diseases, our study aims to showcase the effectiveness and superiority of our approach compared to state-of-the-art CNN-based models for rice leaf disease recognition.
摘要:水稻叶片上细菌、病毒和真菌病害的发生严重影响了水稻生产,对满足全球对主要作物的需求构成了挑战。虽然水稻叶片病害的检测至关重要,但现有方法受到图像背景和拍摄条件的限制。卷积神经网络(CNN)模型已成为识别水稻叶片病害的有效途径,但目前的方法在应用于独立数据集时识别率下降,并且受到需要大规模网络参数的限制。在本项目中,我们提出了一种基于 CNN 的创新模型,旨在通过减少网络参数来缓解这些挑战。通过训练多个基于 CNN 的模型来识别三种常见的水稻叶病,我们的研究旨在展示我们的方法与最先进的基于 CNN 的水稻叶病识别模型相比的有效性和优越性。

In this project, we propose an innovative CNN-based model aimed at mitigating these challenges by reducing network parameters. Through training multiple CNN- basedmodels to identify three common rice leaf diseases, our study aims to showcase the effectiveness and superiority of our approach compared to state-of-the-art CNN-based models for rice leaf disease recognition.","PeriodicalId":13718,"journal":{"name":"International Journal for Research in Applied Science and Engineering Technology","volume":"29 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141795337","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}

Abstract: This experimental investigation explores the impact of incorporating zeolite powder as a partial replacement for fine aggregate, along with silica fume and cashew nut shell ash (CNSA) as partial replacements for cement in concrete. Zeolite, a natural aluminosilicate mineral, is known for its pozzolanic properties, which can enhance the mechanical and durability characteristics of concrete. Silica fume, a byproduct of silicon and ferrosilicon alloy production, is renowned for its high silica content and fineness, contributing to the strength and density of concrete. Cashew nut shell ash, an agricultural waste product, offers a sustainable alternative to traditional cementitious materials, potentially reducing the environmental footprint of concrete production. This experimental study investigated the effects of partially replacing fine aggregate with zeolite powder (5%,10% and 15%) and cement with silica fume (3%,6%,9%,12% and 15%) and cashew nut shell ash (5%,7.5%,10%,12.5%,15% and 17.5%) on the properties of concrete. This study underscores the viability of using zeolite powder, silica fume, and CNSA in sustainable concrete production, contributing to the development of more environmentally friendly construction materials. Further research is recommended to explore the long-term performance and environmental benefits of these alternative materials in concrete applications.
摘要:本实验研究探讨了在混凝土中掺入沸石粉部分替代细骨料以及硅灰和腰果壳灰(CNSA)部分替代水泥的影响。沸石是一种天然铝硅酸盐矿物,因其具有可提高混凝土机械性能和耐久性能的沸石特性而闻名。硅灰是硅和硅铁合金生产的副产品,因其二氧化硅含量高、细度好而闻名,有助于提高混凝土的强度和密度。腰果壳灰是一种农业废料,可作为传统胶凝材料的可持续替代品,从而减少混凝土生产对环境的影响。这项实验研究调查了用沸石粉(5%、10% 和 15%)部分替代细骨料,用硅灰(3%、6%、9%、12% 和 15%)和腰果壳灰(5%、7.5%、10%、12.5%、15% 和 17.5%)替代水泥对混凝土性能的影响。这项研究强调了在可持续混凝土生产中使用沸石粉、硅灰和腰果壳灰的可行性,有助于开发更环保的建筑材料。建议进一步开展研究,探索这些替代材料在混凝土应用中的长期性能和环境效益。
