This article provides an assessment of combinational technique for maximum power reduction in the transmitter of long-term evolution (LTE). An intelligent combination has been presented using constellation extension and scrambling technique in the Orthogonal Frequency Division Multiplexing (OFDM) structure. The principle of this arrangement approach is to apply approximate gradient project (AGP) and partial transmit sequence (PTS) on the OFDM subcarrier. The simulation results show that the proposed approach reduce the PAPR as compared to traditional techniques and maintain the bit error rate (BER) performance of the system especially at low signal to noise ratio (SNR).

The Genetic Algorithm is practical to resolve the obstacles of tiny samples and provide better prognostication for non linear behaviors and it is desirable for the Dissolved Gas Analysis in Power Transformers. The GA generates the initial accumulation at random prosper and scrutiny space faster and modifies the global search cognition and convergent speed. As question arises whether the data was nonlinear or not? It was decided to do the data analysis first. Thus the gas concentration in ppm (parts per million) of all the DGA samples was checked for non linearity.
遗传算法在解决小样本障碍和非线性行为预测方面具有较好的实用性,是电力变压器溶解气体分析的理想方法。该算法能够更快地在随机搜索空间和审查空间生成初始积累,提高全局搜索认知和收敛速度。问题是数据是否是非线性的?决定先做数据分析。因此,所有DGA样品的气体浓度以ppm(百万分之一)为单位进行非线性检查。

Vehicular ad hoc network is a rising direction of research in improves network and communication. It is a type of ad hoc network in which there is a decentralized type ofwireless network. It is a communication less which makes them powerless against assaults like dos. The incoming traffic flooding the victim originates from many different sources. this effectively makes it impossible to stop the attack simply by blocking a single source. an existing paper they used maliciousand irrelevant packet detection algorithm for detecting malicious node on the basis of node velocity and the frequency of packet generated depend on node maximum velocity. Basically vehicles move with speedy which cannot efficaciousrecognize malicious nodes. in our proposed work, we calculatethe average speed of vehicles and check the performance ofvehicles so that we can recognize the true malicious nodes thenapplying reliable function to detect malicious nodes. In our results, we improved packet delivery ratio, routing overheadand throughput of the network.
车载自组织网络是改进网络和通信的一个新兴研究方向。它是一种自组织网络,其中有一种分散类型的无线网络。这是一种交流的减少,使他们对像dos这样的攻击无能为力。淹没受害者的传入流量来自许多不同的来源。这有效地使得仅仅通过阻止单个源来阻止攻击是不可能的。在已有的一篇论文中,他们采用基于节点速度的恶意无关数据包检测算法来检测恶意节点,而生成数据包的频率取决于节点的最大速度。车辆移动速度较快,无法有效识别恶意节点。在我们提出的工作中,我们计算车辆的平均速度并检查车辆的性能,以便我们能够识别真正的恶意节点,然后应用可靠的功能来检测恶意节点。在我们的结果中,我们改进了数据包传送率、路由开销和网络吞吐量。

Visual concept detection is the task of determining concept present in image or video by extracting low level features and training of classifiers in general. Researchers have used various features and classifiers for concept detection. In this paper performance evaluation of fusion of features and classifier is presented. Color moment, HSV histogram, wavelet transform and combination of these features have been used in proposed system. Artificial Neural Network (ANN) and Support Vector Machine (SVM) are employed for classification. The proposed system is implemented on Corel 1K image dataset and Trecvid 2007 benchmark video dataset. The system performance is evaluated using predictive measures of precision, recall and f score. Using simple fusion of features average precision of SVM classifier is better than ANN. The proposed global feature fusion based method is simple yet effective in concept detection task.

This paper proposes a novel Sixth Sense Teaching Aid (SSTA) which incorporates sixth sense technology in projectors for educational purpose. The Projector-PC system was earlier used only for displaying the presentations but with the aid of the proposed system, users can touch on any projected surfaces for interaction purpose. In the SSTA system, the graphical user interface (GUI) buttons are projected on any flat surface like wall and it deals with touch detection of the projected screen using red color parameter both for still image and real time images. The algorithm to perform touch detection is executed in two stages: 1) Feature extraction and button’s touch detection using red color thresholding algorithm which reduces the computational complexity of the processing module; and 2) Performance of assigned operation according to touch action judgment. New born technology named Sixth Sense technology is also implemented in SSTAfor getting relevant information from the internet, whenever we touch any projected Figure or headline. The proposed SSTA system is able to do real time touch detection with 97 percent accuracy which is demonstrated through projected GUI and using a data set collected under different settings of illumination variation, hand orientation and occlusion.
本文提出了一种将第六感技术应用于投影仪的新型第六感教具(SSTA)。投影仪-个人电脑系统早先仅用于显示演示文稿,但在拟议系统的帮助下,用户可以触摸任何投影表面以进行交互。在SSTA系统中,图形用户界面(GUI)按钮投影在任何平面上,如墙壁,它处理投影屏幕的触摸检测使用红色参数对静止图像和实时图像。触摸检测算法分两个阶段执行:1)特征提取和按钮触摸检测,采用红色阈值算法,降低了处理模块的计算复杂度;2)根据触摸动作判断执行指定操作。新诞生的技术第六感技术也被应用于ssta,当我们触摸到任何投影的数字或标题时,它可以从互联网上获取相关信息。所提出的SSTA系统能够以97%的准确率进行实时触摸检测,这通过投影GUI和使用在不同光照变化,手方向和遮挡设置下收集的数据集来证明。

The Projector-PC system was earlier used only for displaying the presentations but with the aid of the proposed system, users can touch on any projected surfaces for interaction purpose. In the SSTA system, the graphical user interface (GUI) buttons are projected on any flat surface like wall and it deals with touch detection of the projected screen using red color parameter both for still image and real time images. The algorithm to perform touch detection is executed in two stages: 1) Feature extraction and button’s touch detection using red color thresholding algorithm which reduces the computational complexity of the processing module; and 2) Performance of assigned operation according to touch action judgment. New born technology named Sixth Sense technology is also implemented in SSTAfor getting relevant information from the internet, whenever we touch any projected Figure or headline. The proposed SSTA system is able to do real time touch detection with 97 percent accuracy which is demonstrated through projected GUI and using a data set collected under different settings of illumination variation, hand orientation and occlusion.","PeriodicalId":6575,"journal":{"name":"2018 International Conference on Advanced Computation and Telecommunication (ICACAT)","volume":"19 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87245861","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}
