Intelligence and Electronic Warfare: Challenges and Future Trends 情报和电子战:挑战和未来趋势
Ali Al-Khawaja, S. Sadkhan
the subjective evaluation of electronic intelligence and warfare has been adopted as quantitive analysis by many organizational bodies to assess defense systems capabilities. One prominent case is the reliance of United States Army on subjective evaluations to drive its systems capabilities based on particular battlefield requirements due to the nonexistence of analytical instruments to meet such goals. Therefore, there is a pressing need to thoroughly review a comprehensive and effective approach for empirically evaluating the impact of intelligence and electronic warfare systems on combat effectiveness. In this direction, we discuss the main important capabilities of electronic intelligence and warfare systems that are necessary for ensuring fielded force mix and greater chance to success on the battlefield. However, the difficulty of the current battle is to process comprehensive electronic warfare (EW) information in a short period of time. Therefore, in this paper, the information system is proposed through the development of Electronic Warfare Intelligent Information System (EWIIS) which contracts electronic warfare processing, communications, radar, maps, warfare missions…etc. thus, aimed This system is at achieving the best performance in spite of the existence of antagonistic influences. Moreover, in this paper, we inclination discuss the design and implementation of a system case study.
电子情报和战争的主观评估已被许多组织机构采用作为定量分析来评估防御系统能力。一个突出的例子是,由于不存在满足这些目标的分析工具,美国陆军依靠主观评价来推动其基于特定战场需求的系统能力。因此,迫切需要彻底审查一种全面有效的方法,以经验评估情报和电子战系统对战斗力的影响。在这个方向上,我们讨论了电子情报和战争系统的主要重要能力,这些能力是确保野战部队混合和在战场上取得更大成功机会所必需的。然而,当前作战的难点在于如何在短时间内处理综合电子战信息。因此,本文通过发展电子战智能信息系统(EWIIS)提出了信息系统,该系统集电子战处理、通信、雷达、地图、作战任务等为一体。尽管存在对抗性影响,该系统仍能达到最佳性能。此外,在本文中,我们倾向于讨论一个系统的设计和实现案例研究。

Robust Image Encryption Based on Double Hyper Chaotic Rabinovich System 基于双超混沌Rabinovich系统的鲁棒图像加密
Huda H. Alsaabri, Saad S. Hreshee
an essential characteristic of chaotic systems is the difficulty in predicting the path of the chaotic time series and the size of the keyspace, which is very large compared to other encryption methods. This paper presents a new image encryption technique depending on a random bitstream generation method through a double Rabinovich hyperchaotic system. The proposed algorithm (Hyper Chaotic Rabinovich System (HCRS)) has been achieved in several ways. Each technique was examined in balanced and delay environments. Then an XOR operation will be done between the bits with the same index of the original image bits and the generated bits to obtain the encrypted image. The HCRS results showed that the balance in random bits between Zeros and Ones are equal in all proposed methods. The Pick Signal to Noise Ratio (PSNR) between the original and the encrypted images is (8.6262). The second significant result in this paper is that the keyspace is very large, more potent than 10ˆ288.
混沌系统的一个本质特征是难以预测混沌时间序列的路径和密钥空间的大小,这与其他加密方法相比是非常大的。通过双Rabinovich超混沌系统,提出了一种基于随机比特流生成方法的图像加密新技术。提出的算法(超混沌拉宾诺维奇系统(HCRS))有几种实现方法。每种技术都在平衡和延迟环境中进行了测试。然后在原始图像位与生成的位具有相同索引的位之间进行异或运算,得到加密后的图像。HCRS结果表明,在所有方法中,0和1之间的随机比特的平衡是相等的。原始图像和加密图像之间的拾取信噪比(PSNR)为(8.6262)。本文的第二个重要结果是键空间非常大,比10 * 288更有效。

Deep Radial Basis Function Networks 深度径向基函数网络
Mohie M. Alqezweeni, V. Gorbachenko, D. A. Stenkin
The use of radial basis functions networks as physics-informed neural networks for solving direct and inverse boundary value problems is demonstrated. On the Levenberg-Marquardt basis optimization method, algorithms have been developed for solving partial differential equations. Comparison of the gradient descent method and the Levenberg-Marquardt method for solving the Poisson equation is given. To solve a direct boundary value problem describing processes in a piecewise homogeneous environment, an algorithm is proposed based on solving individual problems for each region with different properties of the environment associated with the conjugation conditions. It removes restrictions on the radial basis functions used. To solve the coefficient inverse problem of recovering the properties of the piecewise inhomogeneous medium, an algorithm based on parametric optimization is proposed. An algorithm uses two networks of radial basis functions. The first network approximates the solution to the direct problem. And another network approximates a function which describes the properties of the environment. Network learning is performed using an algorithm developed by the authors based on the Levenberg-Marquardt method. Expressions are obtained for the analytical calculation of the Jacobi matrix elements in the Levenberg-Marquardt method and the residual gradient vector elements. The application of the developed algorithms is demonstrated by the example of model direct boundary value problems and inverse coefficient boundary value problems for piecewise homogeneous media.
利用径向基函数网络作为物理信息神经网络来解决正边值和反边值问题。在Levenberg-Marquardt基优化方法的基础上,开发了求解偏微分方程的算法。给出了求解泊松方程的梯度下降法和Levenberg-Marquardt法的比较。为了求解分段齐次环境中描述过程的直接边值问题,提出了一种基于求解与共轭条件相关的环境的不同性质的每个区域的单独问题的算法。它消除了对所用径向基函数的限制。针对恢复分段非均匀介质性质的系数逆问题,提出了一种基于参数优化的算法。一种算法使用两个径向基函数网络。第一个网络近似于直接问题的解。另一个网络近似于描述环境属性的函数。网络学习使用作者基于Levenberg-Marquardt方法开发的算法进行。得到了Levenberg-Marquardt法中Jacobi矩阵元素和残差梯度向量元素解析计算的表达式。以分段齐次介质的模型直接边值问题和逆系数边值问题为例,说明了该算法的应用。

Face Direction Estimation based on Mediapipe Landmarks 基于Mediapipe地标的人脸方向估计
Arqam M. Al-Nuimi, Ghassan J. Mohammed
Many studies had been presented to estimate face direction that relied on training images. A small portion of these studies relied on mathematical calculations with poor results. This paper proposed implementing of trigonometric functions to estimate face direction by using detected landmarks. These landmarks had been detected using the 3D model of (Mideapipe) method. Among there detected landmarks, several points are selected as predicted landmarks. The angles among extended lines from these selected landmarks have been measured to calculate the directions of the human head. The experimental results showed that proposed method achieved high performance with very low error ratio (0.055) for Yaw angle, (0.046) for Pith angle and (0.025) for Roll angle. The difference was approximately ±0.5 degree between real and predicted measures.
目前已有许多基于训练图像的人脸方向估计研究。这些研究中有一小部分依靠数学计算,结果很差。本文提出利用检测到的地标实现三角函数估计人脸方向。使用(midideapipe)方法的三维模型检测这些地标。在检测到的地标中,选择几个点作为预测地标。测量了这些选定的地标的延伸线之间的角度,以计算人类头部的方向。实验结果表明,该方法取得了较好的性能,横摆角误差比(0.055)、俯仰角误差比(0.046)、横摇角误差比(0.025)非常低。实际测量值与预测值之间的差异约为±0.5度。

Parameters Estimation for Modified Weibull Distribution Using Some Methods of Estimators with Simmulation 基于仿真估计器的修正威布尔分布参数估计
Loay Waadallh Saleem, H. Saieed
This paper concerned with the parameters estimation of modified Weibull distribution (MWD) depending on complete data. The least squares (L.S.) and maximum likelihood (M.L.) methods used for parameters estimation. The results applied on simulated samples with different sizes and different values for scale and shape parameters. The mean square error (MSE) criterion is used for the comparison between estimators in different cases. It is concluded that the sample size has a negative effect on the values of (MSE). This result gave an indicator to the researcher there is no need to use larger samples of sizes than or equal to (50). This indication built on the fact that the improvement in (MSE) is very small which can be ignored. On the other hand the increasing values on a scale parameter have a positive effect on (MSE).

Generating digital images of skin diseases based on deep learning 基于深度学习生成皮肤疾病的数字图像
H. M. Ahmed, M. Kashmola
Data generation systems and architectures seek to create new and valuable data with specific sizes and characteristics which are similar to the original data that fit the mechanism of the application used. GANs (generative adversarial network architectures) are a type of generative modeling that uses deep learning methods like convolutional neural networks to generate data, particularly digital images which are used in scientific applications. The goal of this paper is to design and build three architectures of Generative adversarial network (based on convolutional neural networks) to generate three types of digital images of skin diseases by defining two supervised models, the generator model that is trained to generate new digital images and the discrimination model that classifies digital images as real or fake from the field. An intelligent architecture for training the generative model was created, where the two models are trained together in a zero-sum field. Each digital image that was generated differs in its accuracy, size, and dimensions. After applying all the architectures, obtaining and comparing digital images, it turns out that the fewer dimensions of the resulting digital images, the faster the generation processes and the lower the memory costs, but their accuracy is low. The importance of building architecture lies in increasing the images of skin diseases to be used in the data set to perform classification operations for these diseases, as digital images were generated in different sizes, which are 64×64, 128×128, and 512×512, and the new images were obtained with accuracy commensurate with the requirements of this paper. The generated digital images with dimensions 128×128 gave the best results in the accuracy of the resulted images. At the same time, they do not consume much memory, which leads to their processing speed.
数据生成系统和体系结构寻求创建具有特定大小和特征的新的有价值的数据,这些数据与适合所使用的应用程序机制的原始数据相似。GANs(生成对抗网络架构)是一种生成建模,它使用卷积神经网络等深度学习方法来生成数据,特别是在科学应用中使用的数字图像。本文的目标是设计和构建生成对抗网络(基于卷积神经网络)的三种架构,通过定义两个监督模型来生成三种类型的皮肤病数字图像,即训练生成新数字图像的生成器模型和从现场对数字图像进行真假分类的判别模型。创建了一个用于训练生成模型的智能架构,其中两个模型在零和领域中一起训练。生成的每个数字图像在精度、大小和尺寸上都有所不同。应用所有的体系结构,获得数字图像并进行比较,结果表明,得到的数字图像维数越少,生成速度越快,存储成本越低,但精度较低。建筑结构的重要性在于增加数据集中用于对这些疾病进行分类操作的皮肤病图像,因为生成了不同尺寸的数字图像,分别为64×64, 128×128和512×512,并且获得的新图像的精度与本文的要求相匹配。生成的尺寸为128×128的数字图像在结果图像的准确性方面给出了最好的结果。同时,它们不消耗太多内存,这导致了它们的处理速度。

Energy Aware Nature inspired Routing for Wireless Sensor Networks 能量感知自然启发的无线传感器网络路由
Yasameen Sajid Razooqi, M. Al-Asfoor
One of the most critical issues in Wireless Sensor Networks (WSNs) is energy consumption, because of the battery limitation in each sensor. Most energy is consumed on communication phase between the sensor nodes in WSNs, therefore, an accurate routing model is required for managing the communication in WSN. In this paper, a nature inspired flat routing for wireless sensor networks has been introduced with the aim of optimising the energy consumption by improving the routing process. Ant Colony Optimisation algorithm (ACO) has been adopted to facilitate the routing decisions which have to be taken by every node. Furthermore, ACO-based Flat Routing Protocol has been compared with two other algorithms, namely: Random Walk Algorithm and Energy Based Routing in addition to the traditional ACO used in routing. Experimental results have shown a promising improvement in energy consumption, system stability and better lifetime with ACO than the other algorithms. Also, the model has shown better transmission balance with ACO even with extreme scenarios of multi-hop flat routing.
无线传感器网络(WSNs)中最关键的问题之一是能量消耗,因为每个传感器的电池都是有限的。在无线传感器网络中,大部分能量消耗在传感器节点之间的通信阶段,因此需要一个精确的路由模型来管理无线传感器网络中的通信。本文介绍了一种受自然启发的无线传感器网络平面路由,其目的是通过改进路由过程来优化能耗。采用蚁群优化算法(蚁群优化算法)来简化每个节点必须做出的路由决策。此外,除了传统的蚁群算法外,还将基于蚁群算法的平面路由协议与随机行走算法和基于能量的路由算法进行了比较。实验结果表明,与其他算法相比,蚁群算法在能量消耗、系统稳定性和寿命方面有很大的改善。同时,在极端的多跳平坦路由情况下,该模型也表现出较好的传输平衡。
