Data deduplication technology is known as lossless data compression strategy primarily focuses on the strategy of deletion of repeated data. So, with the use of this technology the cost of data transmission and storage can be considerably reduced. In the facebook or whatsapp applications there is a huge volume of image and video data. If a celebrity tweets on twitter then it will be broadcasted. Famous images are also duplicated number of times. If similar operations of this type occur every time, it will cause a lot of waste of available storage space on the server. So just to increase available storage volume is not going to eradicate the problem. So there should be an image deduplication process that should be applied to the all available social networks worldwide. To increase the security in the deduplication system, it is proposed that the image will be encrypted as well as decrypted with a convergent encryption key which is acquired by mathematical computing the hash cost of the available image data. So there is need of encryption, compression and data deduplication strategy to deal with this type of situation. So the main objective of this paper is to propose a new hybrid compression strategy that can compress the data at suitable dimensions with the help of a suitable encryption technique at client side before compression mechanism. In the end of process the final image of fed to server for the purpose of image deduplication strategy that can remove or delete the duplicated data. Comparison of proposed scheme with the existing searchable encryption schemes with respect to memory size will also be done. The comparison results show the efficiency of proposed scheme.
重复数据删除技术又称无损数据压缩策略,主要关注重复数据的删除策略。因此,使用该技术可以大大降低数据传输和存储的成本。在facebook或whatsapp应用程序中,有大量的图像和视频数据。如果一个名人在推特上发推文,那么它就会被广播。著名的图像也被复制了很多次。如果每次都执行类似的操作,会造成服务器可用存储空间的大量浪费。因此,仅仅增加可用存储容量并不能根除这个问题。因此,应该有一个图像重复删除的过程,应该应用于世界上所有可用的社交网络。为了提高重复数据删除系统的安全性,提出用一个收敛的加密密钥对图像进行加密和解密,该密钥通过对可用图像数据的哈希代价进行数学计算获得。因此有必要采用加密、压缩和重复数据删除策略来应对这种情况。因此,本文的主要目标是提出一种新的混合压缩策略,该策略可以在压缩机制之前在客户端使用合适的加密技术将数据压缩到合适的维度。在处理的最后,将最终的图像馈送到服务器,用于图像重复数据删除策略,可以删除或删除重复的数据。将所提出的方案与现有的可搜索加密方案在内存大小方面进行比较。对比结果表明了所提方案的有效性。

Attention is being devoted towards Electro active polymers (EAP) acting as the soft artificial muscles (actuators) which can produce large deformation on the application of low driving voltages (<5 V) and can be applied for soft catheter, robotic arms, sensors and actuator applications. In this work, the vibration analysis of beam structure of Polyvinylidene Fluoride (PVDF) and its composite are done through Finite Element Analysis (FEA). A rectangular beam is designed and optimized for consideration in cantilever configuration. ANSYS 14 R software was used for driving the FE model of the soft beam. The optimized model was again studied for both end fixed boundary conditions. FEA is used to determine the mode shapes and the natural frequencies of PVDF and its composite. The change obtained in the beam structure at different mode shapes is used for predicting the damage and for safe working conditions of the complex structures containing piezoelectric material.

In this research paper, design & simulation of a super wide band microstrip patch antenna, a ultrawideband (UWB) microstrip filter and a UWB microstrip filtenna using HFSS vs 15 software have been proposed. Firstly, a rectangular shape monopole patch antenna and a parallel coupled microstrip UWB bandpass filter (BPF) are separately designed. The proposed antenna is designed on a low cost FR4 substrate with height of 1.6mm and loss tangent of 0.02. The antenna is then integrated with UWB bandpass filter. The integrated antenna filter system is called UWB filtering antenna or filtenna. Simulated results in the terms of peak gain and bandwidth for the proposed antenna are obtained 5.9 dBi and 16.9 GHz in the frequency range 3.1 to 20 GHz, respectively. It is seen that the BPF shows the simulated transmission characteristics in the entire UWB band in better extend. The simulated result of the proposed filtenna exhibits better frequency response in UWB range as well as better out of band rejection capability. Compact size and bandwidth of the proposed UWB microstrip filtenna which exhibits better UWB band characteristics are obtained as 15 x 27 mm2 and 7.46 GHz in the frequency range 3.1 to 10.6 GHz, respectively.
本文采用HFSS vs 15软件对超宽带微带贴片天线、超宽带(UWB)微带滤波器和超宽带微带滤波器进行设计与仿真。首先,分别设计了矩形单极贴片天线和并联耦合微带UWB带通滤波器。该天线设计在低成本的FR4基板上,高度为1.6mm,损耗正切为0.02。然后将天线与UWB带通滤波器集成。集成天线滤波系统称为超宽带滤波天线或滤波器。仿真结果表明,在3.1 ~ 20 GHz频率范围内,天线的峰值增益为5.9 dBi,带宽为16.9 GHz。可以看出,BPF在整个UWB波段内的模拟传输特性得到了更好的扩展。仿真结果表明,该滤波器在超宽带范围内具有较好的频率响应和较好的带外抑制能力。在3.1 ~ 10.6 GHz频率范围内,所设计的超宽带微带滤波器尺寸紧凑,带宽为15 × 27 mm2, 7.46 GHz,具有较好的超宽带特性。

This paper proposes a current mode low input and high output impedance multi-function filter and a sinusoidal quadrature oscillator, both employing two Voltage Differencing Current Conveyors (VDCC) as active elements along with four grounded passive components. Availability of high pass, band pass and low pass filter functions along with independent tunability of its quality factor are the available feature of the designed active filter. By applying some simple modifications in circuit hardware filter network converts into a current/voltage mode single resistance-controlled oscillator (SRCO) circuit. Explicit current outputs, simple and independent oscillation and frequency condition are the paramount features of the derived quadrature oscillator. The validity of both the derived circuits have been performed using pen-paper as well as with software simulations.

Potato is one of the largest food crop and an integral part of world’s food supply. Late Bligh in Potato is community disease and has capability to devastate the entire crop rapidly. Estimated average annual loss form PLB is 15% around the world. In presented work, the task of Factor Analysis and epidemiology prediction are assigned to SVM and ELM respectively for Potato Late Blight. Factor Analysis Model calculate the weights of the Climate based parameters depending on their relevance in deciding the blight and blight free year. The feature subset selected using SVM are used as input to ELM for epidemiology prediction along with the age of the plant. Two databases are prepared from AICRP and Climate Data, one for Factor Analysis and one for Epidemiology prediction with five class labels (1-5). Database for Epidemiology Prediction is further divided into three sub databases for three separate planting dates. Analysis of the experimental results for Factor analysis shows that Maximum temperature, Maximum and Minimum Humidity, Sun Shine hours and Evaporation plays major role in occurrence of late blight disease. Experiments are conducted for Epidemiology Prediction with other activation functions and different partitions of database. On the basis of obtained results, SinC activation Function outperformed sigmoid function and has promising accuracy for all the data partitions.
马铃薯是世界上最大的粮食作物之一,是世界粮食供应的重要组成部分。马铃薯晚疫病是一种群体性病害,具有迅速毁灭整个马铃薯的能力。据估计,全球每年因PLB造成的平均损失为15%。本文将马铃薯晚疫病的因子分析和流行病学预测任务分别分配给支持向量机和ELM。因子分析模型根据气候参数在决定枯萎病和无枯萎病年份中的相关性来计算其权重。使用SVM选择的特征子集作为ELM的输入,随植物的年龄进行流行病学预测。从AICRP和Climate Data中准备了两个数据库,一个用于因子分析,一个用于流行病学预测,有五个分类标签(1-5)。流行病学预测数据库根据三个不同的种植日期进一步划分为三个子数据库。因子分析表明,最高温度、最大和最小湿度、日照时数和蒸发量对晚疫病的发生起主要作用。利用其他激活函数和不同的数据库分区进行流行病学预测实验。在得到的结果基础上,SinC激活函数优于sigmoid函数,对所有数据分区都有很好的准确性。
