Placement of nodes has been the major challenge in wireless sensor networks. The data reported from a sensor is only useful when the position of that sensor is found. In this context, several techniques have been proposed to conserve power consumption and to prolong the lifetime of the wireless sensor networks. In this paper, we propose a new algorithm that accurately finds the best locations of sensors while minimizing the average energy consumed in the network. More precisely, we consider a critical network in each sensor satisfying its own missions and depending on its locations. In addition to fulfill their mission, the sensor tries to maintain a good neighboring nodes quality. we determine the location of node by using two criteria: the cost and the quality of communication. The aim of this work is to develop a new algorithm so as to solve the complicated optimization problem posed in this case while minimize the total energy consumption. Our simulation results demonstrate that our algorithm is very advantageous in terms of convergence to the appropriate locations.
节点的放置一直是无线传感器网络的主要挑战。从传感器报告的数据只有在找到该传感器的位置时才有用。在这种情况下,已经提出了几种技术来节省功耗和延长无线传感器网络的寿命。在本文中,我们提出了一种新的算法,可以准确地找到传感器的最佳位置,同时最小化网络中的平均能量消耗。更准确地说,我们考虑每个传感器中的关键网络满足其自己的任务并取决于其位置。除了完成自己的任务外,传感器还试图保持良好的相邻节点质量。我们通过两个标准来确定节点的位置:通信成本和通信质量。本工作的目的是开发一种新的算法来解决这种情况下的复杂优化问题,同时使总能耗最小。仿真结果表明,该算法在收敛到合适位置方面具有很大的优势。

This research tried to create software that can detect lung cancer as a comparison of the work of medical practitioners using artificial neural networks (ANN), with X-ray movies taken from the tool diagnostic radiography (DR) stored in the compact disc. The dependent variable observation in this study is the identification of DR X-ray image size of 1024 x 1024 pixels. A total of 10 images X-ray which has been observed by the physician radiology. With 5 images X-ray normal and 5 images lung cancer. In this study, the image processing is done through three stages: neighborhood averaging, median filter and histogram equalization. The result of these features are grouped in normal categories. From test results stating the truth 80%. To facilitate the user in the lung disease pattern recognition. GUI applications design using MATLAB. We use some form of image processing which includes form training andtesting. The best parameters obtained from this research include learning rate=0.3, the number of hidden layer=30 and tolerance error=10-8.

Vision-based flame detection has drawn significant attention in the past decade with camera surveillance systems becoming ubiquitous. This paper proposes a multi criterion method to detect fire or flames by processing the video data generated by a high speed camera. Since flame images are special class of images, some of the unique features of a flame may be used to identify flame. There are some differences between flame images and other general images. By using these features we are able to detect fire correctly with least false alarm. In this paper we present an algorithm which can detect fire and reduce number of false alarms by counting number of identified pixels. In the algorithm, we preprocess the images to have better results. So first we adjust the gray level of a flame image according to its statistical distribution to have better processing. After that we try to extract fire features in images. First by using color characteristics, the ratio of red to green, we can identify probable fire-like or fire like pixels. Second, to highlight the regions with high gray level contrast at their edges, we use the extended prewitt filter. We use AND operation on two above processing images to remove unrelated pixels, at last by using flicker frequency, the oscillating change in the number of identified pixels over time is transformed into the frequency domain to complete detection algorithm. Simulation proves the algorithm ability to detect fire in different situations in video sequences.
在过去的十年中,随着摄像机监控系统的普及,基于视觉的火焰检测引起了人们的极大关注。通过对高速摄像机产生的视频数据进行处理,提出了一种多准则的火灾或火焰检测方法。由于火焰图像是一类特殊的图像,火焰的一些独特特征可以用来识别火焰。火焰图像与其他一般图像之间存在一些差异。通过使用这些特征,我们能够以最少的误报正确地检测火灾。本文提出了一种通过计算识别像素数来检测火灾并减少误报警的算法。在算法中,我们对图像进行预处理以获得更好的效果。因此,我们首先根据火焰图像的统计分布对其灰度值进行调整,以获得更好的处理效果。然后,我们尝试提取图像中的五个特征。首先,通过使用颜色特征,即红绿比,我们可以识别可能的类似火或类似火的像素。其次,为了突出边缘灰度对比度高的区域,我们使用了扩展的prewitt滤波器。我们对上述两幅处理图像进行AND运算去除不相关的像素点,最后利用闪烁频率将识别像素点数量随时间的振荡变化转换到频域完成检测算法。仿真验证了该算法在视频序列中不同情况下的火灾检测能力。

Recently, shape-based matching and retrieval of 3D polygonal models has become one of the most fundamental problems in computer vision. Dealing with families of objects instead of a single one may impose further challenges on regular geometric algorithms. In this paper we focus on the classification of 3D objects based on their geodesic distance & path calculated on a mesh using an iterative algorithm for solving the Eikonal equation. For the classification process, we use both Multiclass Support Vector Machine (M-SVM) classifier,K-Nearest Neighbors (KNN), Decision Tree (DT) and Artificial Neural Networks (ANN) to better evaluate our descriptors. We illustrate the potential of extracted characteristics by two 3D benchmarks. The recognition rates achieved in all experiments show that a small number of curve between 9 and 12 can correctly categorize a family of 3D objects.
近年来,基于形状的三维多边形模型匹配与检索已成为计算机视觉领域的一个最基本的问题。处理对象族而不是单个对象可能会给常规几何算法带来进一步的挑战。在本文中,我们重点研究了基于网格上计算的测地线距离和路径的三维物体分类,使用迭代算法求解Eikonal方程。对于分类过程,我们使用多类支持向量机(M-SVM)分类器、k -近邻(KNN)、决策树(DT)和人工神经网络(ANN)来更好地评估我们的描述符。我们通过两个3D基准来说明提取特征的潜力。所有实验的识别率表明,在9 ~ 12之间的少量曲线可以正确地对一类三维物体进行分类。

In this paper we study the problem of combining low-level visual features for semantic image annotation. The problem is tackled with a two different approaches that combines texture, color and shape features via a Bayesian network classifier. In first approach, vector concatenation has been applied to combine the three low-level visual features. All three descriptors are normalized and merged into a unique vector used with single classifier. In the second approach, the three types of visual features are combined in parallel scheme via three classifiers. Each type of descriptors is used separately with single classifier. The experimental results show that the semantic image annotation accuracy is higher when the second approach is used.
本文研究了结合底层视觉特征进行语义图像标注的问题。这个问题是通过贝叶斯网络分类器结合纹理、颜色和形状特征的两种不同的方法来解决的。在第一种方法中,向量拼接被用于组合三个低级视觉特征。这三个描述符被归一化并合并成一个唯一的向量,用于单个分类器。在第二种方法中,三种类型的视觉特征通过三个分类器并行组合。每种类型的描述符与单个分类器单独使用。实验结果表明,采用第二种方法时,语义图像标注的准确率更高。

The problem is tackled with a two different approaches that combines texture, color and shape features via a Bayesian network classifier. In first approach, vector concatenation has been applied to combine the three low-level visual features. All three descriptors are normalized and merged into a unique vector used with single classifier. In the second approach, the three types of visual features are combined in parallel scheme via three classifiers. Each type of descriptors is used separately with single classifier. The experimental results show that the semantic image annotation accuracy is higher when the second approach is used.","PeriodicalId":247642,"journal":{"name":"TELKOMNIKA Indonesian Journal of Electrical Engineering","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130550547","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}

Non linear loads are highly effected by variations in voltages. Dynamic voltage restorer is one of the most popular compensating devices due to its low cost and better performance. Usage of Park’s transformation technique effectively reduces the rating of Dynamic voltage restorer. Application of fuzzy logic controller for getting the better result is proposed in this paper. The results are verified in Matlab/Simulink environment.
非线性负载受电压变化的影响很大。动态电压恢复器因其成本低、性能好而成为目前最受欢迎的补偿器件之一。利用Park变换技术有效地降低了动态电压恢复器的额定值。本文提出了模糊控制器的应用,以获得较好的效果。在Matlab/Simulink环境下对结果进行了验证。
