Bidirectional in recent years, Deep learning performance in natural scene image processing has improved its use in remote sensing image analysis. In this paper, we used the semantic segmentation of remote sensing images for deep neural networks (DNN). To make it ideal for multi-target semantic segmentation of remote sensing image systems, we boost the Seg Net encoder-decoder CNN structures with index pooling & U-net. The findings reveal that the segmentation of various objects has its benefits and drawbacks for both models. Furthermore, we provide an integrated algorithm that incorporates two models. The test results indicate that the integrated algorithm proposed will take advantage of all multi-target segmentation models and obtain improved segmentation relative to two models.
近年来,深度学习在自然场景图像处理中的双向性能提高了其在遥感图像分析中的应用。本文将遥感图像的语义分割用于深度神经网络(DNN)。为了使其适合遥感图像系统的多目标语义分割,我们用索引池和U-net增强了Seg网编码器-解码器CNN结构。研究结果表明,两种模型对不同目标的分割各有优缺点。此外,我们还提供了一个集成了两个模型的算法。测试结果表明,所提出的综合算法能够充分利用所有的多目标分割模型,获得相对于两种模型更好的分割效果。

Noise in the communication channel is wellestablished to be a threat to digital bit transmission, resulting inmany mistakes at the bit level. Different modulation methods arestudied in terms of BER, probability of error and SNR to bettercomprehend this. In the presence of specific levels of noise in thecommunication channel, this analysis yields an interestingconclusion that advises the employment of particular modulationmethods. A comprehensive analysis of several modulationschemes has been considered. Those include On-Off Keymodulation (OOK), Binary Phase Shift Key (BPSK), QuadraturePhase Shift Key (QPSK), Pulse Amplitude Modulation (PAM) and8-Phase Shift Key (8-PSK). This analysis can aid in the selectionof a modulation approach based on the channel condition.
通信信道中的噪声是数字比特传输的一大威胁,它会导致比特级的错误。为了更好地理解这一点,我们从误码率、误差概率和信噪比方面研究了不同的调制方法。在通信信道中存在特定水平的噪声时,该分析得出了一个有趣的结论,建议采用特定的调制方法。对几种调制方案进行了综合分析。其中包括开关键调制(OOK),二进制相移键(BPSK),正交相移键(QPSK),脉冲幅度调制(PAM)和8相移键(8-PSK)。这种分析有助于根据信道条件选择调制方法。

电力需求日益增加,不可再生能源发电无法满足需求。替代能源是满足电力需求的唯一解决方案。太阳能发电以其光伏效应起主要作用。这种太阳能光伏系统效率很低。功率半导体器件和转换电路以及电感/磁路。逆变电路对光伏发电产生影响,在提高效率的同时提高输出电压水平。本文提出了一种新型的无变压器直流-交流变换器,与传统的带变压器逆变器相比,该变换器效率高,成本低。无变压器自换相光伏逆变器体现了中心逆变器和串逆变器的优点。它提供了高输出功率和低成本的转换器。这些变压器较少的DC-AC转换器与boost /Buck-Boost转换器连接,以获得更好的输出。因此,该提议的DC-AC转换器拓扑结构不需要机械开关,并且尺寸更轻。光伏技术发电效率低,成本高。提出的无变压器光伏逆变器是提高系统实用性和降低充电率的较好选择。

This research paper deals with the characterization of friction stir welding aluminium 7108 with twin stir technology. The coupons of the above metal were friction stir welded using a cylindrical pin with counter-rotating twin stir technology using at constant speed 900, 1200, 1500,1800 with four different feed rates of 30,50,70,90 mm/min. Microstructure examination showed the variation of each zone and their influence on the mechanical properties. Also, tensile strength and hardness measurements were done as a part of the mechanical characterization and correlation between mechanical and metallurgical properties and deduced at the speed of 1500 rpm. Friction stir welding process parameters such as tool rotational speed (rpm), tool feed (mm/min) were considered to find their influence on the tensile strength (MPa) and hardness (HRB). A genetic algorithm (GA) was employed by taking the fitness function as a combined objective function to optimize the friction welding process parameters to predict the maximum value of the tensile strength and hardness. The confirmation test also revealed good closeness to the genetic algorithm predicted results and the optimized value of process parameters for different weights of the tensile and hardness have been predicted in the model.

A Novel Approach of Image Fusion Techniques using Ant Colony Optimization 一种基于蚁群优化的图像融合新方法
Pub Date : 2021-06-30 DOI: 10.35940/ijitee.h9241.0610821

Ant Colony Optimization (ACO) is a relatively high approach for finding a relatively strong solution to the problem of optimization. The ACO based image fusion technique is proposed. The objective function and distance matrix is designed for image fusion. ACO is used to fuse input images at the feature-level by learning the fusion parameters. It is used to select the fusion parameters according to the user-defined cost functions. This algorithm transforms the results into the initial pheromone distribution and seeks the optimal solution by using the features. As to relevant parameters for the ACO, three parameters (α, β, ρ ) have the greatest impact on convergence. If the values of α, β are appropriately increased, convergence can speed up. But if the gap between these two is too large, the precision of convergence will be negatively affected. Since the ACO is a random search algorithm, its computation speed is relatively slow.
蚁群优化算法(Ant Colony Optimization, ACO)是一种较高级的方法,用于寻找较强的优化问题解。提出了基于蚁群算法的图像融合技术。设计了图像融合的目标函数和距离矩阵。蚁群算法通过学习融合参数对输入图像进行特征级融合。用于根据用户自定义的代价函数选择融合参数。该算法将结果转化为初始信息素分布,并利用特征寻求最优解。对于蚁群算法的相关参数,α、β、ρ三个参数对收敛性影响最大。适当增大α、β值,可以加快收敛速度。但如果两者之间的差距过大,则会对收敛精度产生负面影响。由于蚁群算法是一种随机搜索算法,其计算速度相对较慢。

Detecting the driver's drowsiness in a consistentand confident manner is a difficult job because it necessitatescareful observation of facial behaviour such as eye-closure,blinking, and yawning. It's much more difficult to deal with whenthey're wearing sunglasses or a scarf, as seen in the datacollection for this competition. A drowsy person makes a varietyof facial gestures, such as quick and repetitive blinking, shakingtheir heads, and yawning often. Drivers' drowsiness levels arecommonly determined by assessing their abnormal behavioursusing computerised, nonintrusive behavioural approaches. Usingcomputer vision techniques to track a driver's sleepiness in anon-invasive manner. The aim of this paper is to calculate thecurrent behaviour of the driver's eyes, which is visualised by thecamera, so that we can check the driver's drowsiness. We present adrowsiness detection framework that uses Python, OpenCV, andKeras to notify the driver when he feels sleepy. We will useOpenCV to gather images from a webcam and feed them into aDeep Learning model that will classify whether the person's eyesare "Open" or "Closed" in this article.
以一种持续而自信的方式检测司机的睡意是一项困难的工作,因为它需要仔细观察司机的面部行为,如闭眼、眨眼和打哈欠。从这次比赛的数据收集中可以看出,当他们戴着太阳镜或围巾时,处理起来要困难得多。一个昏昏欲睡的人会做出各种各样的面部动作,比如快速重复地眨眼、摇头和经常打哈欠。司机的困倦程度通常是通过使用计算机化的非侵入性行为方法评估他们的异常行为来确定的。使用计算机视觉技术以无创的方式跟踪司机的睡意。本文的目的是计算驾驶员眼睛的当前行为,这是由摄像头可视化的,这样我们就可以检查驾驶员的睡意。我们提出了一个使用Python、OpenCV和keras的嗜睡检测框架,当司机感到困倦时通知他。我们将使用opencv从网络摄像头收集图像,并将其输入深度学习模型,该模型将在本文中对人的眼睛是“打开”还是“关闭”进行分类。

Recently, as wireless communication and smart phone spread and technology develop, there is an increasing demand for a system capable of real-time communication and business processing using online information anytime, anywhere in the offline field. In particular, changes in digital signage technology are developing in various ways due to the development of advanced convergence technologies. With the development of convergence technologies, digital signage has been constructed to provide information through a structured structure between each component in order to develop in a form that can deliver information in response to environmental changes rather than user input. This paper developed a system that outputs and services various contents together with industrial facility inspection and management by using wireless communication Bluetooth in a display device equipped with an operating system. This system is an Internet-of-Things-based system that simultaneously outputs various contents and a business management function that enables facility inspection.
近年来,随着无线通信和智能手机的普及和技术的发展,人们越来越需要一种能够在离线领域随时随地利用在线信息进行实时通信和业务处理的系统。特别是由于先进的融合技术的发展,数字标牌技术的变化正在以各种方式发展。随着融合技术的发展,数字标牌已经被构建为通过每个组件之间的结构化结构来提供信息,以便以一种能够响应环境变化而不是用户输入的形式来传递信息。本文在配有操作系统的显示设备中,利用无线通信蓝牙技术,开发了一套能够输出并服务于工业设施检查管理等多种内容的系统。该系统是一个基于物联网的系统,可以同时输出各种内容,并具有业务管理功能,可以进行设施检查。

In current research, artificial neural network (ANN) and Multi objective genetic algorithm (MOGA) have been used for the prediction and multi objective optimization of the end milling operation. Cutting speed, feed rate, depth of cut, material density and hardness have been considered as input variables. The predicted values and optimized results obtained through ANN and MOGA are compared with experimental results. A good correlation has been established between the ANN predicted values and experimental results with an average accuracy of 91.983% for material removal rate, 99.894% for tool life, 92.683% for machining time, 92.671% for tangential cutting force, 92.109% for power and 90.311% for torque. The MOGA approach has been proposed to obtain the cutting condition for optimization of each responses. The MOGA gives average accuracy of 96.801% for MRR, 99.653% for tool life, 86.833% for machining time, 93.74% for cutting force, 93.74% for power and 99.473% for torque. It concludes that ANN and MOGA are efficiently and effectively used for prediction and multi objective optimization of end milling operation for any selected materials before the experimental. Implementation of these techniques in industries before the experimentation is useful to reduce the lead time, experimental cost and power consumption also increase the productivity of the product.
目前的研究主要采用人工神经网络(ANN)和多目标遗传算法(MOGA)对立铣削工序进行预测和多目标优化。切削速度、进给量、切削深度、材料密度和硬度作为输入变量。将人工神经网络和MOGA得到的预测值和优化结果与实验结果进行了比较。人工神经网络预测值与实验结果具有良好的相关性,材料去除率、刀具寿命、加工时间、切向切削力、功率和扭矩的平均精度分别为91.983%、99.894%、92.683%、92.671%和92.109%。提出了MOGA方法来获得各响应优化的切削条件。MOGA的平均精度为MRR的96.801%,刀具寿命的99.653%,加工时间的86.833%,切削力的93.74%,功率的93.74%和扭矩的99.473%。结果表明,ANN和MOGA可有效地用于实验前任意选择材料的立铣削工艺预测和多目标优化。这些技术在工业实验前的实施有助于缩短交货时间,实验成本和功耗,也提高了产品的生产率。
