Q2 Engineering Pub Date : 2023-01-10 DOI: 10.30534/ijeter/2023/061112023
In the race conditions of the Energy Saving Car Contest, urban concept vehicles must comply with the special rules that have been set, namely 'stop & go driving'. Therefore, the designed car must have the toughness to accelerate and decelerate safely. Chassis is a fundamental part of the vehicle that functions to support the overall load that works on the car, keeps the car's condition rigid, does not experience excessive deformation and is safe when used. For that chassis design planning must be considered. The selection of a strong but still lightweight material was carried out, using 6061 aluminum material. In this research, an analysis will be carried out on the design of the TITEN EV-2 car chassis. TITEN itself is the name of the Jember University research team that focuses on developing energy-efficient electric vehicles. In this study the analysis is focused on the chassis that experiences dynamic loading when braking with variations in the shape of the chassis profile, namely profiles in the shape of a square and hollow rectangle and the braking distance is varied. from 20m, 15m, 10m. By using the Finite Element Method (FEM), the strength analysis of the chassis structure design can be determined by looking at the maximum stress and total deformation acting on the chassis. From the simulation results, the rectangular hollow chassis profile has a mass of 7.6 kg which is lighter than the square hollow chassis which has a mass of 9.4 kg. Rectangular hollow chassis has a maximum stress that is superior to square hollow chassis at loading distances of 20 m and 15 m, but at a braking distance of 10 m, square hollow chassis is superior in terms of total deformation and maximum stress
在节能车大赛的比赛条件下,城市概念车必须遵守已经制定的特殊规则,即“走走停停”。因此,所设计的汽车必须具有安全加速和减速的韧性。底盘是车辆的基本组成部分,其功能是支撑汽车上的整体负载,保持汽车的状态刚性,不会经历过度变形,并且在使用时是安全的。因此,必须考虑底盘设计规划。选择了一种坚固但仍然轻便的材料,使用6061铝材料。在本研究中,将对天腾EV-2汽车底盘的设计进行分析。TITEN本身是Jember大学研究团队的名字,该团队专注于开发节能电动汽车。在本研究中,重点分析了在不同的底盘轮廓形状,即不同的方形和空心矩形轮廓以及不同的制动距离下,底盘在制动时所承受的动载荷。从20米,15米,10米。利用有限元法,通过观察作用在底盘上的最大应力和总变形来确定底盘结构设计的强度分析。从仿真结果来看,矩形空心底盘轮廓的质量为7.6 kg,比方形空心底盘的质量9.4 kg轻。矩形空心底盘在加载距离为20 m和15 m时的最大应力优于方形空心底盘,但在制动距离为10 m时,方形空心底盘的总变形和最大应力均优于方形空心底盘

Electric vehicles (EVs) are gradually taking place of the conventional fossil fuel-based vehicles. However, popularity of EVs is hindered due to longer charging time and lower mileage. To address the mileage issue, in this paper we have proposed to use wind turbines to be mounted on vehicle, so that it can harness the wind energy to charge the batteries while the vehicle is in motion. We have designed two types of wind turbines: horizontal axis and vertical axis turbines and our analysis showed that vertical axis turbines provide better solution in extracting maximum wind power.
电动汽车正在逐渐取代传统的化石燃料汽车。然而,电动汽车的普及受到了阻碍,因为充电时间更长,里程数更低。为了解决里程问题,在本文中,我们建议使用安装在车辆上的风力涡轮机,以便在车辆行驶时利用风能为电池充电。我们设计了两种类型的风力涡轮机:水平轴和垂直轴涡轮机,我们的分析表明,垂直轴涡轮机在提取最大风力方面提供了更好的解决方案。

NegML: A Privacy-Preserving Machine Learning Approach Based on Negative Database NegML:一种基于负数据库的隐私保护机器学习方法
Q2 Engineering Pub Date : 2023-01-10 DOI: 10.30534/ijeter/2023/021112023
Machine learning has become an increasingly prominent subject in the age of big data. It has made significant advances in image identification, object detection, and natural language processing, among other areas. The initial aim of machine learning is to extract meaningful information from enormous amounts of data, which unavoidably raises privacy concerns. Numerous privacy-preserving machine-learning approaches have been presented so far. However, most of them suffer from significant improvements in efficiency or accuracy. A negative database (NDB) is a data representation that may safeguard data privacy by storing and exploiting the complementary form of original data. In this research, we provide NegML, a privacy-preserving machine learning approach based on NDB. Private data are first transformed to NDB before being fed into machine learning algorithms such as a Multilayer perceptron (MLP), Logistic regression (LR), Gaussian naive Bayes (GNB), Decision tree (DT), as well as Random forest (RF). NegML has the same computational complexity as the original machine learning algorithms without privacy protection. Experiment findings on heart illnesses, milk datasets, Car evaluation benchmark datasets and Blood fusion dataset show that the accuracy of NegML is equivalent to the original machine learning model in most circumstances, as well as the technique based on differential privacy.
在大数据时代,机器学习已经成为一门日益突出的学科。它在图像识别、目标检测和自然语言处理等领域取得了重大进展。机器学习的最初目的是从海量数据中提取有意义的信息,这不可避免地引发了对隐私的担忧。到目前为止,已经提出了许多保护隐私的机器学习方法。然而,它们中的大多数在效率或准确性方面都有显著的改进。负数据库(NDB)是一种数据表示形式,可以通过存储和利用原始数据的补充形式来保护数据隐私。在本研究中,我们提供了一种基于NDB的隐私保护机器学习方法NegML。私有数据首先转换为NDB,然后再输入机器学习算法,如多层感知器(MLP)、逻辑回归(LR)、高斯朴素贝叶斯(GNB)、决策树(DT)以及随机森林(RF)。在没有隐私保护的情况下,NegML具有与原始机器学习算法相同的计算复杂度。在心脏病、牛奶数据集、汽车评估基准数据集和血液融合数据集上的实验结果表明,在大多数情况下,NegML的准确率与原始机器学习模型相当,基于差分隐私的技术也是如此。

Design of Improved 3D Radar charts for Multidimensional Data Visualization 面向多维数据可视化的改进三维雷达图设计
Q2 Engineering Pub Date : 2022-12-09 DOI: 10.30534/ijeter/2022/0110122022
The rapid growth of Technology is leading to the exploration of data at a very deep level. This has caused data to increase exponentially at very high rates increasing the complexity of the relation between them. Multidimensional data thus come into existence and multidimensional data visualization tools help to understand the complexity of the relationship between data efficiently. Radar charts being very simple, easy, and more understandable due to their ability to reduce the complexity of the relationship between data plays a very important role in visualization. But radar charts still contain a few limitations that are being analyzed during this work. Radar charts are significant in many applications thus the work proposes a design for an improved 3D version of the Radar chart that can solve the problem in existing radar charts and achieve benchmarking.

Implementing a Hybrid method For Fake News Detection 一种假新闻检测的混合方法实现
Q2 Engineering Pub Date : 2022-12-09 DOI: 10.30534/ijeter/2022/0210122022
The increasing consumption of news on social media platforms is mainly due to its cheap and attractive nature and it’s capable of spreading the fake news. The spread of fake news has negative effects on society. Some people make it up to get attention or gain political gain. Machine learning and deep learning techniques have been developed to detect fake news. However, they tend to generate inaccurate reports. To detect fake news, we used a Hybrid model that combines SVM and Naive Bayes (NBSVM) framework. It was able to classify the news with an accuracy of 84.85%. This model was tested and trained on a fake news challenge dataset. We used various evaluation metrics (precision, recall, F1- measure, etc.) to measure the model's efficiency

Biomechanics and Surface Activity in Simulated Body Fluid of Antibiotic Intramedullary Nail 抗生素髓内钉在模拟体液中的生物力学和表面活性
Q2 Engineering Pub Date : 2022-11-07 DOI: 10.30534/ijeter/2022/0110112022
Intramedullary nail continues to evolve with the introduction of new technologies as it is considered a gold standard in treating bone defects caused by disease, trauma and accidents which are evidently higher in developing countries like the Philippines. Recently, Philippine Orthopedic Center introduced the usage of Antibiotic Intramedullary Nails (ABIMN), a threaded stainless rod coated with antibiotic cement to treat infections that commonly occurs in bone defects. The product has been widely used, however, no biomechanical study was made to demonstrate and test the coronal bending, cyclic axial loading and chemical properties of the ABIMN. The researchers compared the biomechanical properties and surface activity when immersed in Simulated Body Fluid (SBF) of the Antibiotic Intramedullary Nail (ABIMN), Küntscher Intramedullary Nail (KIMN), and Intramedullary Nail with Interlocking screws (IMNIS). A total of 37 Intramedullary Nail (IMN) models were used for the biomechanical study, while the 4 remaining nails were used for the SBF immersion test. A very high positive correlation between bending rigidity and radius to the 4th power in ABIMN was found. Median Young’s modulus of elasticity on the other hand, significantly differs across the three groups. Further analysis showed that the median value was significantly lower in ABIMN compared to KIMN (p=0.0027) and IMNIS (p=0.0025) concluding that the ABIMN can be left for 6 weeks, with the patient on partial weight bearing up to 25% of an average 75kg man. The chemical properties of the ABIMN however, revealed that it is safe to use and has qualitatively comparable corrosion properties of KIMN when immersed in SBF. For easier removal of the ABIMN and after completion of both oral and IV antibiotics at 6 weeks post op; it still advisable to remove the ABIMN and perform exchange nailing at the said timeframe.
随着新技术的引入,髓内钉继续发展,因为它被认为是治疗由疾病、创伤和事故引起的骨缺损的金标准,而在菲律宾等发展中国家,这一比例显然更高。最近,菲律宾骨科中心介绍了抗生素髓内钉(ABIMN)的使用,这是一种涂有抗生素水泥的螺纹不锈钢棒,用于治疗骨缺损中常见的感染。该产品已被广泛使用,然而,没有进行生物力学研究来证明和测试ABIMN的冠状弯曲,循环轴向载荷和化学性质。研究人员比较了抗生素髓内钉(ABIMN)、k ntscher髓内钉(KIMN)和带互锁螺钉的髓内钉(IMNIS)浸泡在模拟体液(SBF)中时的生物力学特性和表面活性。采用37枚髓内钉(IMN)模型进行生物力学研究,其余4枚髓内钉进行SBF浸泡试验。在ABIMN中,弯曲刚度与半径的四次方之间存在非常高的正相关关系。另一方面,中位杨氏弹性模量在三组之间有显著差异。进一步的分析表明,与KIMN (p=0.0027)和IMNIS (p=0.0025)相比,ABIMN的中位值显著降低,结论是ABIMN可以保留6周,患者的部分体重可达到平均75kg男性的25%。然而,ABIMN的化学性质表明,它是安全的,并且在浸泡在SBF中时具有与KIMN质量相当的腐蚀性能。在术后6周完成口服和静脉抗生素治疗后,更容易去除ABIMN;但仍建议在上述时间框架内移除ABIMN并进行交易所钉钉。

Forest fires are natural disasters and effective mitigation of these fires require early warning systems. Deployment of sensors that are robust against environmental conditions, collection of sensor data in an energy efficient manner and at real time at the central server, and accurate detection of fire’s existence are all critical elements for implementing such systems. In this paper, we focus on second issue which is energy efficient routing of sensor data in a Internet-of-Things (IoT) sensor network that is deployed for forest fire detection. A Fuzzy-based Cluster Head selection technique for WSN in detecting forest fire is presented. In the proposed scheme, the nodes are divided into clusters using K-means clustering and then the cluster heads are determined by using a fuzzy logic scheme. Unlike traditional parameters, distance from the centroid and the remaining energy levels are used as parameters to select the cluster head. Simulation tool is used to implement the proposed technique. The simulation results suggest that the proposed cluster head selection approach outperforms the existing schemes
森林火灾是自然灾害,有效缓解这些火灾需要早期预警系统。部署对环境条件具有鲁棒性的传感器、以节能的方式在中央服务器实时收集传感器数据以及准确检测火灾的存在,都是实现此类系统的关键要素。在本文中,我们关注的第二个问题是物联网(IoT)传感器网络中传感器数据的节能路由,该网络用于森林火灾检测。提出了一种用于森林火灾探测的WSN的模糊簇头选择技术。在该方案中,使用K-means聚类将节点划分为簇,然后使用模糊逻辑方案确定簇头。与传统参数不同,距离质心的距离和剩余能级被用作选择簇头的参数。仿真工具用于实现所提出的技术。仿真结果表明,所提出的簇头选择方法优于现有方案
