Nowadays, software vulnerabilities pose a serious problem, because cyber-attackers often find ways to attack a system by exploiting software vulnerabilities. Detecting software vulnerabilities can be done using two main methods: i) signature-based detection, i.e. methods based on a list of known security vulnerabilities as a basis for contrasting and comparing; ii) behavior analysis-based detection using classification algorithms, i.e., methods based on analyzing the software code. In order to improve the ability to accurately detect software security vulnerabilities, this study proposes a new approach based on a technique of analyzing and standardizing software code and the random forest (RF) classification algorithm. The novelty and advantages of our proposed method are that to determine abnormal behavior of functions in the software, instead of trying to define behaviors of functions, this study uses the Word2vec natural language processing model to normalize and extract features of functions. Finally, to detect security vulnerabilities in the functions, this study proposes to use a popular and effective supervised machine learning algorithm.
如今,软件漏洞是一个严重的问题,因为网络攻击者经常通过利用软件漏洞来找到攻击系统的方法。检测软件漏洞可以使用两种主要方法:i)基于签名的检测,即基于已知安全漏洞列表的方法,作为对比和比较的基础;ii)使用分类算法的基于行为分析的检测,即基于分析软件代码的方法。为了提高准确检测软件安全漏洞的能力,本研究提出了一种基于软件代码分析和标准化技术以及随机森林(RF)分类算法的新方法。我们提出的方法的新颖性和优势在于,为了确定软件中函数的异常行为,本研究使用Word2vec自然语言处理模型来规范和提取函数的特征,而不是试图定义函数的行为。最后,为了检测函数中的安全漏洞,本研究提出使用一种流行且有效的监督机器学习算法。

The implementation of industrial revolution 4.0 in manufacturing industries is necessary to adapt to the rapid changes of technologies. The milling process is one of the common manufacturing processes applied in the industries to produce engineering products. The vibration that occurs in the milling process can disturb the continuity of the process. The wired vibration monitoring system implemented in the manufacturing process needs to be replaced with the wireless monitoring system. Hence wireless vibration monitoring system is developed to solve the problem with wired monitoring systems where tucked cable and high cost are the main challenges of the wired monitoring system. The wireless monitoring system setup is built using three components: sensor node, monitoring node, and base station. Milling experiments with various depths of cut, feed rate, and spindle speed were conducted to examine the performance of the wireless monitoring system. The results indicate the wireless system shows similar data recorded by the wired system. The wireless vibration monitoring system can identify the effect of milling parameters such as depth of cut, feed rate, and spindle speed on the vibrations level. The effect of cut depth is more significant than spindle speed and feed rate in the defined parameters.
在制造业实施工业革命4.0是为了适应技术的快速变化。铣削工艺是工业中用于生产工程产品的常见制造工艺之一。铣削过程中发生的振动可能会干扰加工过程的连续性。在制造过程中实施的有线振动监测系统需要用无线监测系统取代。因此,开发无线振动监测系统是为了解决有线监测系统的问题,有线监测系统面临的主要挑战是电缆堵塞和成本高。无线监控系统的设置使用三个组件:传感器节点、监控节点和基站。通过对不同切削深度、进给速度和主轴转速的铣削实验,检验了无线监测系统的性能。结果表明,无线系统显示了有线系统记录的类似数据。无线振动监测系统可以识别切削深度、进给速度和主轴速度等铣削参数对振动水平的影响。在定义的参数中,切削深度的影响比主轴速度和进给速度更显著。

The Sidoarjo mud flow in East Java is the result of a natural phenomenon in which hot mudflow occurs due to volcanic activity. The Sidoarjo mud flow resulted in a considerable ecological disaster in the area. In this study, by using the Modification of Normalized Difference Water Index (MNDWI) technique we measured the extension of the mudflow area from 2013 to 2020 using Landsat 8 satellite data imagery. This study is meant to predict the extension of the mud flow area in the research site by comparing regression and neural network techniques in order to find the best approach. The RPROP MLP neural network technique was used to predict the Sidoarjo mud-flowing area in 2021 to 2025. Surprisingly the results of these calculations showed that the RPROP MLP neural network with three hidden layers and 20 neurons performed the best, with an R square value for training of 0.77915565 and for testing of 0.78321550.
东爪哇的Sidoarjo泥流是火山活动引起的热泥流自然现象的结果。Sidoarjo泥石流在该地区造成了严重的生态灾难。在这项研究中,通过使用归一化差异水指数修正(MNDWI)技术,我们使用陆地卫星8号卫星数据图像测量了2013年至2020年泥流区域的扩展。本研究旨在通过比较回归和神经网络技术来预测研究场地泥石流面积的扩展,以找到最佳方法。采用RPROP-MLP神经网络技术对2021年至2025年Sidoarjo泥浆流动面积进行了预测。令人惊讶的是,这些计算的结果表明,具有三个隐藏层和20个神经元的RPROP-MLP神经网络表现最好,训练的R平方值为0.77915565,测试的R平方为0.78321550。

Tomatoes are popular around the world due to their high nutritional value. Tomatoes are also one of the world’s most widely cultivated and profitable crops. The distribution and marketing of tomatoes depend highly on their quality. Estimating tomato ripeness is an essential step in determining shelf life and quality. With the abundant supply of tomatoes on the market, it is exceedingly difficult to estimate tomato ripeness using human graders. To address this issue and improve tomato quality inspection and sorting, automated tomato maturity classification models based on different features have been developed. However, current methods heavily rely on human-engineered or handcrafted features. Convolutional neural networks have emerged as the preferred technique for general object recognition problems because they can automatically detect and extract valuable features by directly working on input images. This paper proposes a CNN-ELM classification model for automated tomato maturity grading that combines CNNs’ automated feature learning capabilities with the efficiency of extreme learning machines to perform fast and accurate classification even with limited training data. The results showed that the proposed CNN-ELM model had a classification accuracy of 96.67% and an F1-score of 96.67% in identifying six maturity stages from the test data.
西红柿因其高营养价值而在世界各地广受欢迎。番茄也是世界上种植最广泛、利润最高的作物之一。番茄的分销和营销在很大程度上取决于它们的质量。估计番茄成熟度是决定保质期和质量的重要步骤。由于市场上番茄供应充足,使用人工分级器估计番茄成熟度极其困难。为了解决这一问题并改进番茄质量检测和分类,开发了基于不同特征的番茄成熟度自动分类模型。然而,目前的方法在很大程度上依赖于人工设计或手工制作的功能。卷积神经网络已成为一般对象识别问题的首选技术,因为它们可以通过直接处理输入图像来自动检测和提取有价值的特征。本文提出了一种用于番茄成熟度自动分级的CNN-ELM分类模型,该模型将CNN的自动特征学习能力与极限学习机器的效率相结合,即使在有限的训练数据下也能进行快速准确的分类。结果表明,所提出的CNN-ELM模型在从测试数据中识别六个成熟阶段方面的分类准确率为96.67%,F1得分为96.67%。

Mobile Robot is an extremely essential technology in the industrial world. Optimal path planning is essential for the navigation of mobile robots. The firefly algorithm is a very promising tool of Swarm Intelligence, which is used in various optimization areas. This study used the firefly algorithm to solve the mobile robot path-planning problem and achieve optimal trajectory planning. The objective of the proposed method is to find the free-collision-free points in the mobile robot environment and then generate the optimal path based on the firefly algorithm. It uses the A∗ algorithm to find the shortest path. The essential function of use the firefly algorithm is applied to specify the optimal control points for the corresponding shortest smooth trajectory of the mobile robot. Cubic Polynomial equation is applied to generate a smooth path from the initial point to the goal point during a specified period. The results of computer simulation demonstrate the efficiency of the firefly algorithm in generating optimal trajectory of mobile robot in a variable degree of mobile robot environment complexity.

This work presents the composition of a new algorithm for a stereo vision system to acquire accurate depth measurement from stereo correspondence. Stereo correspondence produced by matching is commonly affected by image noise such as illumination variation, blurry boundaries, and radiometric differences. The proposed algorithm introduces a pre-processing step based on the combination of Contrast Limited Adaptive Histogram Equalization (CLAHE) and Adaptive Gamma Correction Weighted Distribution (AGCWD) with a guided filter (GF). The cost value of the pre-processing step is determined in the matching cost step using the census transform (CT), which is followed by aggregation using the fixed-window and GF technique. A winner-takes-all (WTA) approach is employed to select the minimum disparity map value and final refinement using left-right consistency checking (LR) along with a weighted median filter (WMF) to remove outliers. The algorithm improved the accuracy 31.65% for all pixel errors and 23.35% for pixel errors in nonoccluded regions compared to several established algorithms on a Middlebury dataset.
这项工作提出了一种用于立体视觉系统的新算法的组成,以从立体对应中获得准确的深度测量。通过匹配产生的立体对应通常受到图像噪声的影响,例如照明变化、模糊边界和辐射差异。该算法引入了一个基于对比度限制自适应直方图均衡(CLAHE)和自适应伽玛校正加权分布(AGCWD)与引导滤波器(GF)相结合的预处理步骤。预处理步骤的成本值在匹配成本步骤中使用普查变换(CT)确定,然后使用固定窗口和GF技术进行聚合。采用赢者通吃(WTA)方法来选择最小视差图值,并使用左右一致性检查(LR)和加权中值滤波器(WMF)来去除异常值。与Middlebury数据集上的几种已建立算法相比,该算法在所有像素误差的准确率提高了31.65%,在非遮挡区域的像素误差的精度提高了23.35%。

The federated cloud is the future generation of cloud computing, allowing sharing of computing and storage resources, and servicing of user tasks among cloud providers through a centralized control mechanism. However, a great challenge lies in the efficient management of such federated clouds and fair distribution of the load among heterogeneous cloud providers. In our proposed approach, called QPFS_MASG, at the federated cloud level, the incoming tasks queue are partitioned in order to achieve a fair distribution of the load among all cloud providers of the federated cloud. Then, at the cloud level, task scheduling using the Modified Activity Selection by Greedy (MASG) technique assigns the tasks to different virtual machines (VMs), considering the task deadline as the key factor in achieving good quality of service (QoS). The proposed approach takes care of servicing tasks within their deadline, reducing service level agreement (SLA) violations, improving the response time of user tasks as well as achieving fair distribution of the load among all participating cloud providers. The QPFS_MASG was implemented using CloudSim and the evaluation result revealed a guaranteed degree of fairness in service distribution among the cloud providers with reduced response time and SLA violations compared to existing approaches. Also, the evaluation results showed that the proposed approach serviced the user tasks with minimum number of VMs.
联邦云是未来一代云计算,允许云提供商之间共享计算和存储资源,并通过集中控制机制为用户任务提供服务。然而,一个巨大的挑战在于对这种联邦云的有效管理以及在异构云提供商之间公平分配负载。在我们提出的称为QPFS_MASG的方法中,在联邦云级别,对传入任务队列进行分区,以便在联邦云的所有云提供商之间实现负载的公平分配。然后,在云级别,使用贪婪的修改活动选择(MASG)技术的任务调度将任务分配给不同的虚拟机(VM),将任务截止日期视为实现良好服务质量(QoS)的关键因素。所提出的方法负责在截止日期内为任务提供服务,减少违反服务级别协议(SLA)的行为,提高用户任务的响应时间,并在所有参与的云提供商之间实现负载的公平分配。QPFS_MASG是使用CloudSim实现的,评估结果显示,与现有方法相比,云提供商之间的服务分配具有一定程度的公平性,响应时间和违反SLA的情况有所减少。此外,评估结果表明,所提出的方法以最小数量的VM为用户任务提供服务。

The spread of ransomware has risen exponentially over the past decade, causing huge financial damage to multiple organizations. Various anti-ransomware firms have suggested methods for preventing malware threats. The growing pace, scale and sophistication of malware provide the anti-malware industry with more challenges. Recent literature indicates that academics and anti-virus organizations have begun to use artificial learning as well as fundamental modeling techniques for the research and identification of malware. Orthodox signature-based anti-virus programs struggle to identify unfamiliar malware and track new forms of malware. In this study, a malware evaluation framework focused on machine learning was adopted that consists of several modules: dataset compiling in two separate classes (malicious and benign software), file disassembly, data processing, decision making, and updated malware identification. The data processing module uses grey images, functions for importing and Opcode n-gram to remove malware functionality. The decision making module detects malware and recognizes suspected malware. Different classifiers were considered in the research methodology for the detection and classification of malware. Its effectiveness was validated on the basis of the accuracy of the complete process.
在过去的十年里,勒索软件的传播呈指数级增长,给多个组织造成了巨大的经济损失。各种反勒索软件公司提出了防止恶意软件威胁的方法。恶意软件的发展速度、规模和复杂性给反恶意软件行业带来了更多挑战。最近的文献表明,学术界和反病毒组织已经开始使用人工学习以及基本的建模技术来研究和识别恶意软件。传统的基于签名的反病毒程序很难识别不熟悉的恶意软件并跟踪新形式的恶意软件。在本研究中,采用了一个以机器学习为核心的恶意软件评估框架,该框架由几个模块组成:分为两类(恶意软件和良性软件)的数据集编译、文件拆卸、数据处理、决策制定和更新恶意软件识别。数据处理模块使用灰色图像、导入功能和Opcode n-gram来删除恶意软件功能。决策模块检测恶意软件并识别可疑的恶意软件。在恶意软件检测和分类的研究方法中考虑了不同的分类器。在整个过程的准确性的基础上,验证了其有效性。
