Comparative study of copy-move forgery detection techniques 仿移伪造检测技术的比较研究
Mohamed A. Elaskily, H. Aslan, Osama A. Elshakankiry, O. Faragallah, F. El-Samie, M. Dessouky
Digital images and their applications gained a huge interest around the world in several fields like newspapers, social media, defaming persons, and courts. There are two types of digital image authentication. The first type is active authentication, which uses digital signature and image watermarks. These techniques have certain constraints such as knowing the content of the digital image. They need special equipment like cameras and development software. The second type is passive authentication, which is used to detect digital image forgeries represented in image cloning, image splicing, image resampling, image retouching, and image morphing. Passive authentication has an advantage of not needing any previous knowledge of the image content to detect the forgery. Copy-move forgery is the most famous type, and it is widespread in all image forgeries. Copy-move forgery is easy to perform and the forged part has the same properties of the whole image that makes it difficult to detect. There are many algorithms used to detect copy-move forgery attacks depending on different techniques. This paper covers the directions of copy-move forgery detection and gives a wide coverage of earlier copy-move forgery detection algorithms and techniques.
数字图像及其应用在世界各地的几个领域引起了巨大的兴趣,如报纸、社交媒体、诽谤人士和法院。有两种类型的数字图像认证。第一种是主动身份验证,它使用数字签名和图像水印。这些技术有一定的限制,如知道数字图像的内容。他们需要特殊的设备,如相机和开发软件。第二种是被动认证,主要用于检测图像克隆、图像拼接、图像重采样、图像修饰和图像变形等数字图像伪造。被动身份验证的优点是不需要事先了解图像内容来检测伪造。复制-移动伪造是最著名的类型,在所有图像伪造中都很普遍。复制-移动伪造很容易实施,并且伪造的部分具有与整个图像相同的属性,这使得它很难被检测到。根据不同的技术,有许多算法用于检测复制-移动伪造攻击。本文介绍了复制-移动伪造检测的研究方向,并对早期的复制-移动伪造检测算法和技术进行了广泛的介绍。

Human ear recognition using voting of statistical and geometrical techniques 基于统计和几何技术的人耳识别
I. Ziedan, H. Farouk, Shimaa S. Mohamed
Ear recognition gained great importance in the field of pattern recognition due to its simple formulation, and rich characteristics compared to other used biometrics such as the face, iris, and voice and so on. In this paper, we presented a new algorithm for ear recognition based on a voting method between results obtained by three efficient techniques of 2nd level Haar wavelet transform, Histogram of oriented gradient descriptors and geometrical based technique. Firstly, enhancement procedure is applied on the images. Then we developed an ear segmentation technique that selects the resulted ear image from two methods one depends on active ear contour and the other depending on ear edges endpoints connection. After that for every image one feature vector is extracted using the three methods and a matching is tested between testing and registered images by using Euclidian distance. Such that any distance beyond a certain threshold value for each method is a candidate to be for the matched image. Voting between the candidates selects the correct match. The experimental results achieved overall accuracy of 99.6% when applied in images affected by illuminating changes and pose variations.
与人脸、虹膜、声音等生物识别技术相比,耳识别技术以其公式简单、特征丰富等特点,在模式识别领域具有重要意义。本文提出了一种新的人耳识别算法,该算法采用二级Haar小波变换、定向梯度描述子直方图和基于几何的方法对结果进行投票。首先对图像进行增强处理。然后,我们开发了一种耳朵分割技术,从两种方法中选择最终的耳朵图像,一种方法依赖于耳朵的活动轮廓,另一种方法依赖于耳朵边缘端点的连接。然后对每幅图像分别使用三种方法提取一个特征向量,并利用欧式距离对测试图像和配准图像进行匹配测试。使得每一种方法超过一定阈值的任何距离都是匹配图像的候选距离。在候选人之间投票选出正确的配对。实验结果表明,在受光照变化和姿态变化影响的图像中,总体精度达到99.6%。

Maximum power point tracking of photovoltaic system using adaptive fuzzy controller 基于自适应模糊控制器的光伏系统最大功率点跟踪
M. Refaat, Yousry Atia, M. M. Sayed, H. Fattah
This paper exhibits a complete design of maximum power point tracking (MPPT) control scheme based on an adaptive fuzzy controller. This controller is intended to upgrade the efficiency of a photovoltaic (PV) array and to diminish the output power oscillations. The adaptive nature of the proposed controller provides online tuning of fuzzy rules parameters to deal with varying sun radiation and ambient temperature. The adaptive MPPT controller is compared with existing setups, namely the “incremental conductance’ (I.C) technique and fuzzy logic controller (FLC). Simulation results demonstrate the supremacy of the adaptive technique in terms of the speed of tracking and oscillations reduction around the maximum of power-voltage (P-V) curve.

M. Saber, F.M.A. Ghali, E. Elzahab
Distributed Generation (DG) is the key solution for growing demand and higher power quality constraints in the sector of distribution networks. The performance assessment of the DG-equipped feeder is a challenging problem at the planning stage because of the uncertainties involved in both predicting the DG placement and operation. to deduce the effect on protective devices of the distribution network is investigated through simulating the IEEE 37 bus test feeder using PowerFactory (DIgSILENT) software. Three approaches are used; Minimum voltage tracking, Internal busbars and Combined techniques to solve this problem and to set the limits of each technique. The simulation is repeated for different cases at which the location and number of DG units is changed and results are compared to that of the base case (without DG) to study the effect on the short circuit currents level.

Enhancing signal to noise interference ratio for device to device technology in 5G applying mode selection technique 应用模式选择技术提高5G设备间技术的信噪比
Hanan H. Hussein, S. El-kader
Fifth Generation (5G) is the upcoming stage in the development of the entire mobile communication technology. 5G cellular network is expected to offer higher data rates, lower latency, more extended coverage area and capacity, and lower energy consumption than previous cellular networks (i.e. 1G-4G). D2D is considered as one of the key technologies provided to enhance 5G performance. Direct communication among two devices without involvement of any central point (i.e. base station), is defined as device to device (D2D) communication. D2D is considered a vital technique to enhance the performance of mobile cellular networks in terms of Signal to Interference noise ratio and energy efficiency. This paper presents 5G requirements, clarifies D2D technology and states the technology's advantages and applications. Besides that, the effect of mode selection is investigated on the network performance to enhance it. Results show that D2D in case of proximity distance has better results than cellular mode 4 times. Also, shows that using mode selection enhances SINR more than using D2D 2 times or using cellular communication 4 times.
第五代(5G)是整个移动通信技术发展的下一个阶段。5G蜂窝网络预计将提供比以前的蜂窝网络(即1G-4G)更高的数据速率、更低的延迟、更大的覆盖范围和容量,以及更低的能耗。D2D被认为是提高5G性能的关键技术之一。两个设备之间不涉及任何中心点(即基站)的直接通信被定义为设备对设备(D2D)通信。D2D被认为是提高移动蜂窝网络信噪比和能量效率的重要技术。本文提出了5G的需求,阐述了D2D技术,阐述了该技术的优势和应用。此外,为了提高网络性能,还研究了模式选择对网络性能的影响。结果表明,在距离较近的情况下,D2D的效果比蜂窝模式好4倍。此外,使用模式选择比使用D2D的2倍或使用蜂窝通信的4倍提高了SINR。

Performance improvement of the decoding side of the BCS-SPL technique BCS-SPL技术解码端的性能改进
Rasha Shoitan, Z. Nossair, I. Ibrahim, A. Tobal
This paper proposes different approaches to reduce the blurring effect of the reconstructed images and the computational complexity at the decoding side of the block compressive sensing with smooth projected landweber (BCS-SPL). It was found that the reason of the lack of reconstruction quality and computational complexity are due to the use of wiener filter and thresholding method. Therefore, each proposed approach uses a different thresholding method to improve the reconstruction quality and reduce computational complexity. Many simulation experiments have been conducted to evaluate the proposed approaches and compare them to several other conventional compressive sensing techniques. Our simulation results show that the proposed approaches improves the reconstruction quality by up to 5 dB relative to the other conventional techniques and also reduce the computational complexity time.

A. Hebala, W. Ghoneim, H. Ashour
In this paper, the standard equations of PMSG have been utilized to develop model generator basic dimensions; where such primary design has been found unable to deliver the exact required rated power. Hence to reach such required rated output power different approaches depend on improved performance and reduced cost criterion are suggested and studied. Three different dimension changing techniques are studied for the highest efficiency and power to volume ratio through linear analysis, and then compared to finite element model (FEM) analysis results. As a conclusion a modified starting design formula is suggested for designing of high performance PMSGs.

MEMS gyroscope for attitude propagation and determination for nanosatellites 用于纳米卫星姿态传播和测定的MEMS陀螺仪
K. Gaber, S. Nagy, A. Zaki
Cubesat is a nano-satellite system standard, where a nano-satellite has structure, power, telemetry, payload among other subsystems, however, it fits up to 1.3 kilograms and 10cm×10cm×10cm modules [1]. Nano-satellites present flexibility in design; in recent years there are several proposals on how to implement the subsystems. The resolution continued to improve, which in turn lead to the need for higher accuracy pointing. They push the bounds of small size and low cost developed to provide cheap access to space and used primarily by universities, these satellites are measured in the tens of centimeters, weigh between one and ten kilograms, and usually cost in the tens of thousands of dollars.
立方体卫星是一种纳米卫星系统标准,其中纳米卫星具有结构、动力、遥测、有效载荷以及其他子系统,然而,它适合1.3公斤和10cm×10cm×10cm模块[1]。纳米卫星在设计上具有灵活性;近年来,人们对如何实现子系统提出了一些建议。分辨率不断提高,这反过来又导致需要更高的指向精度。它们突破了小尺寸和低成本的限制,主要用于大学,这些卫星的尺寸在几十厘米左右,重量在1到10公斤之间,价格通常在数万美元。
