This paper proposes a method to improve the weight of Particle swarm optimization (PSO) by using similarity, so as to realize the fast and accurate diagnosis of power grid fault. First, a mathematical model of power grid fault diagnosis is established by analyzing the circuit breaker, equipment protection and action information in the power grid. Next, the model is transformed into a 0-1 integer programming problem. Last, the traditional PSO algorithm is improved, so that the inertia weight in the algorithm can be adjusted dynamically according to the concept of similarity. Simulation results show that the improved PSO greatly increases the convergence speed and efficiency of power grid fault diagnosis.

The ability of perception and understanding all static and dynamic objects around vehicle in various driving and environmental conditions represent one of the main requirements for autonomous vehicles and most of Advanced Driving Assistance Systems (ADAS). Current promise to deliver safe ADAS in modern cars could be achieved by convolutional neural network (CNN). In this paper we present a software based on YOLO that is extended with a CNN for traffic sign recognition. Since real time detection is required for safe driving, YOLO network used in this paper is pre trained for detection and classification of only five objects which are separated in categories such as cars, trucks, pedestrians, traffic signs, and traffic lights. Detected traffic signs are further passed to CNN which can classify them in one of 75 categories. We demonstrate the high level of classification confidence by accurately recognition more than 99.2% of examined signs in quite diverse conditions.
在各种驾驶和环境条件下感知和理解车辆周围所有静态和动态物体的能力是对自动驾驶汽车和大多数高级驾驶辅助系统(ADAS)的主要要求之一。目前在现代汽车上提供安全的ADAS的承诺可以通过卷积神经网络(CNN)来实现。本文提出了一种基于YOLO的基于CNN扩展的交通标志识别软件。由于安全驾驶需要实时检测,所以本文使用的YOLO网络只对汽车、卡车、行人、交通标志、红绿灯等5个分类对象进行预训练,进行检测和分类。检测到的交通标志进一步传递给CNN, CNN可以将其分类为75个类别之一。我们通过在相当不同的条件下准确识别超过99.2%的检查信号来证明高水平的分类置信度。

In consumer electronics where sales cycle is about two to three years, and with increased competition and product differentiation faced by suppliers in online distribution channels, it is important to pay attention to targeted marketing in online consumer electronics sales through the use of predictive analytics, as marketing paradigm is becoming increasingly customer-focused and unsolicited marketing is often costly and ineffective due to low response rates. In this study, customer predictive analytical techniques, including the RecencyFrequency Monetary (or RFM) method and classical classification modelling methods – logistic regression, decision tree, neural network and ensemble models – are utilized to improve predictive accuracy. Results from the neural network model shows a significant improvement over RFM model, with positive response rates improving by more than 2x, from 42.9% to 87.2%. However, if stronger explanability power is preferred, decision tree model may be utilized, although predictive accuracy of about 2% is sacrificed. The study discusses predictive modelling useful to improve the performance of positive response rate targeting, alongside the benefits of improved sampling and reduced computing power, especially with significantly large datasets. In real life implementation, it is imperative that companies understand that classification power of the models and marketing campaign targeting are continuous improvement processes. These processes improve with every iteration from its baseline towards its objective threshold level set by the companies’ management. False positive transactions should be investigated, with the effect of incorporating the findings to the improvement of models going forward.
在消费电子产品中,销售周期约为两到三年,随着供应商在在线分销渠道中面临的竞争和产品差异化的加剧,通过使用预测分析来关注在线消费电子产品销售中的目标营销是很重要的,因为营销模式正变得越来越以客户为中心,由于响应率低,未经请求的营销通常是昂贵和无效的。在本研究中,客户预测分析技术,包括最近频率货币(或RFM)方法和经典分类建模方法-逻辑回归,决策树,神经网络和集成模型-用于提高预测精度。神经网络模型的结果表明,与RFM模型相比,神经网络模型的积极响应率提高了2倍以上,从42.9%提高到87.2%。但是,如果需要更强的可解释性,可以使用决策树模型,虽然会牺牲2%左右的预测精度。该研究讨论了预测建模有助于提高积极响应率目标的性能,以及改进采样和降低计算能力的好处,特别是在大量数据集的情况下。在实际实现中,公司必须理解模型的分类能力和营销活动目标是持续改进的过程。这些过程随着从基线到公司管理层设定的目标阈值水平的每次迭代而改进。应该对假阳性交易进行调查,以将研究结果纳入未来模型的改进中。

In this paper, a method for the vehicles detection in the surroundings of an autonomous vehicle and warnings of potential collision with them is presented. The method, which consists of two parts, is implemented in robot operating system (ROS). The first part is used to detect vehicles in an autonomous vehicle environment, in which, YOLO v2 algorithm, trained on a newly created set of images, is used. The YOLO v2 algorithm is configured to detect four classes of objects: a car, a van, a truck, and a bus. The second part of the proposed method is the ROS node for distance assessment. In particular, two ROS nodes for distance assessment are created; one ROS node used for distance assessment in the Carla simulator, while the other ROS node is used for real-world distance assessment. The testing results of the proposed method show promising results.

It wants to follow a world optimal solution to find the best result by removing the limitations such as unknown fitness conditions, instability, noise, as well as much local minimum. This new method is called GA for Best Heating-Cooling Location (GA-FBHCL). According to our prior work which have accommodated the Taguchi method for the aims of Building Energy Modelling (BEM) and optimization to forecast the best heating and cooling appliances location in one of the Toos Arman Star Apartment Hotel units in Mashhad, Iran, now we introduce a new theory and design with the help of GA for this goal which the EM results achieved from the GA-FBHCL method are 5-9% better than the Taguchi method and initial design of room. This approach can be utilized with project developers, policymakers and researchers as a new globally approach in construction industry.

Nowadays software testing in the automotive industry is a very important step in overall software development. The work in this paper is based on a pre-existing special testing environment for Advanced Driver Assistance Systems (ADAS) software solutions which automates the process of testing as much as possible. Within the paper, this environment was analyzed and some of the shortcomings were identified. An alternative solution is proposed which, instead of storing tests in one large dictionary, uses an SQLite database as a storage method. Before integration into the existing environment, a standalone solution was developed. After that, efforts were made to integrate such a solution into the existing environment. While the proposed standalone solution obtains smaller processing time regarding test adding in comparison with existing solution, after integration into the existing environment, the proposed solution obtains slightly higher processing time. However, the proposed approach provides security, robustness and stability of the entire environment with respect to data storage.
目前,汽车行业的软件测试是整个软件开发中非常重要的一步。本文的工作是基于先进驾驶辅助系统(ADAS)软件解决方案的预先存在的特殊测试环境,该环境尽可能地自动化测试过程。本文对这种环境进行了分析,并指出了一些不足之处。提出了另一种解决方案,即使用SQLite数据库作为存储方法,而不是将测试存储在一个大字典中。在集成到现有环境之前,开发了一个独立的解决方案。在此之后,努力将这种解决方案集成到现有环境中。与现有解决方案相比,建议的独立解决方案在添加测试方面获得的处理时间更短,而在集成到现有环境后,建议的解决方案获得的处理时间略高。然而,所提出的方法在数据存储方面提供了整个环境的安全性、健壮性和稳定性。

Due to the unprecedented growth of the internet and portable consumer imaging devices, copyright protection of digital images has become a topical affair. In this paper, a fast Tensor-SVD based red-cyan anaglyph 3D image watermarking has been presented which provides high imperceptibility, and robustness. To integrate the Human Visual System modelling into our framework, integer lifting wavelet transform has been incorporated. After that, the watermark has been infused within the first diagonal matrix generated by Tensor-SVD. The proposed method is free from false positive issues due to its total insertion-based approach. Furthermore, the proposed method is also implemented in a low-power Single Board Computer for seamless integration in personal and industrial consumer imaging devices. Moreover, the watermark’s security has been further increased by encrypting it with Arnold’s Cat Map based cryptic algorithm. Qualitative and quantitative comparison with various state-of-the-art methods justifies the superiority of the suggested algorithm under most form of signal processing, and geometric impairments.
由于互联网和便携式消费成像设备的空前发展,数字图像的版权保护已成为一个热门话题。提出了一种基于张量奇异值分解(svd)的快速红青色浮雕三维图像水印算法,该算法具有较高的不可感知性和鲁棒性。为了将人类视觉系统建模整合到我们的框架中,我们引入了整数提升小波变换。然后,将水印注入到由张量-奇异值分解生成的第一个对角矩阵中。由于该方法完全基于插入,因此不存在误报问题。此外,所提出的方法也在低功耗单板计算机中实现,用于个人和工业消费成像设备的无缝集成。此外,采用基于Arnold Cat Map的加密算法对水印进行加密,进一步提高了水印的安全性。与各种最先进的方法进行定性和定量比较,证明了该算法在大多数形式的信号处理和几何损伤下的优越性。

Enhanced Grey Wolf Algorithm for Energy Efficient Wireless Sensor Networks 高能效无线传感器网络的改进灰狼算法

Wireless sensor networks have entered a period of a rapid development, due to several novel technologies which have emerged in the past few years, such as Internet of Things and cloud computing. Miniature sensor nodes are integral components of numerous complex systems. The biggest problem for any wireless sensor network, in any possible application domain, is to maximize the overall network lifetime by improving the total energy consumption of the network. A large number of clustering algorithms have been implemented in the past decade, with a main goal to balance the energy consumption of each node in the network and to increase energy efficiency - the term known in literature as load balancing. One important representative of these traditional algorithms for load balancing which is still in frequent use is LEACH. On the other hand, swarm intelligence meaheuristics have recently been successfully applied in solving a large number of NP hard problems from the wireless sensor networks domain. In this paper, we propose an improved version of grey wolf algorithm, that has been applied to improve the network lifetime optimization. Grey wolf algorithm was employed in forming the clusters and the cluster head selection process. As a part of our research, we have evaluated the performance of the proposed exploration enhanced grey wolf algorithm by comparing it to the traditional LEACH algorithm, basic grey wolf approach and particle swarm optimization, that were all tested under the same experimental conditions. Obtained results from conducted simulations have proven that our proposed metaheuristics performs better that other considered algorithms.
由于近年来物联网、云计算等新技术的出现,无线传感器网络进入了一个快速发展的时期。微型传感器节点是许多复杂系统的组成部分。对于任何无线传感器网络,在任何可能的应用领域,最大的问题是通过提高网络的总能耗来最大化整个网络的生命周期。在过去的十年中,已经实现了大量的聚类算法,其主要目标是平衡网络中每个节点的能量消耗并提高能源效率-在文献中称为负载平衡。在这些传统的负载平衡算法中,一个重要的代表是LEACH算法。另一方面,群体智能的均值启发式算法近年来已成功地应用于解决无线传感器网络领域的大量NP困难问题。在本文中,我们提出了一种改进的灰狼算法,并将其应用于改进网络寿命优化。在聚类的形成和簇头的选择过程中采用灰狼算法。作为我们研究的一部分,我们将提出的探索增强灰狼算法与传统的LEACH算法、基本灰狼方法和粒子群算法进行了比较,并在相同的实验条件下进行了测试。从进行的模拟中获得的结果证明,我们提出的元启发式算法比其他考虑的算法表现得更好。

The biggest problem for any wireless sensor network, in any possible application domain, is to maximize the overall network lifetime by improving the total energy consumption of the network. A large number of clustering algorithms have been implemented in the past decade, with a main goal to balance the energy consumption of each node in the network and to increase energy efficiency - the term known in literature as load balancing. One important representative of these traditional algorithms for load balancing which is still in frequent use is LEACH. On the other hand, swarm intelligence meaheuristics have recently been successfully applied in solving a large number of NP hard problems from the wireless sensor networks domain. In this paper, we propose an improved version of grey wolf algorithm, that has been applied to improve the network lifetime optimization. Grey wolf algorithm was employed in forming the clusters and the cluster head selection process. As a part of our research, we have evaluated the performance of the proposed exploration enhanced grey wolf algorithm by comparing it to the traditional LEACH algorithm, basic grey wolf approach and particle swarm optimization, that were all tested under the same experimental conditions. Obtained results from conducted simulations have proven that our proposed metaheuristics performs better that other considered algorithms.","PeriodicalId":6731,"journal":{"name":"2020 Zooming Innovation in Consumer Technologies Conference (ZINC)","volume":"48 1","pages":"87-92"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79784182","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}

In order to achieve functionality of autonomous driving, modern vehicles must be aware of theirs surrounding in any given moment. Complex software modules within such systems oversee vehicle’s environment and use this environmental data to pinpoint vehicles position in the world. Often these perception modules process numerous calculations and fuse data acquired from different sensors to achieve, as precise as possible, understanding of vehicles environment. Alongside these highlevel data fusion modules, many modern vehicles have redundant subsystems that handle similar functionality but in smaller scale in order to achieve shorter “Sense-Plan-Act” loop. In this paper we will present prototype for Advance Lane Finding (ALF) application, which could be utilized as an enhancement of multiple ADAS systems. Proposed solution is implemented in C+ + programming language as a part of Autoware/ROS platform. Prototype’s performances are tested on Nvidia DRIVE PX2 hardware platform.
为了实现自动驾驶的功能,现代车辆必须随时了解周围环境。这种系统内的复杂软件模块监控车辆的环境,并利用这些环境数据来确定车辆在世界上的位置。通常,这些感知模块处理大量计算并融合从不同传感器获取的数据,以尽可能精确地理解车辆环境。除了这些高级数据融合模块,许多现代车辆都有冗余的子系统来处理类似的功能,但规模较小,以实现更短的“感知-计划-行动”循环。在本文中,我们将介绍先进车道查找(ALF)应用的原型,该应用可以用作多个ADAS系统的增强。该方案采用c++编程语言作为Autoware/ROS平台的一部分实现。样机在Nvidia DRIVE PX2硬件平台上进行了性能测试。
