Today, banking system has carried banking for the customer's expediency, supporting set of services, where authentication plays a vital role. Due to the fabulous apprehension and growth in the field of hacking, that it is not safe to rely on web to accumulate all the information. So in order to beat this problem we have proposed an efficient algorithm for secured bank cheque authentication by Embedded image Cryptography scheme. It is a cryptographic approach that uses visual information as input, encryption and decryption is done by using human visual system. The proposed method Embedded Visual Cryptography Scheme (EVCS) uses gray threshold with morphological operation for secure transmission of bank cheque over the network. In this approach first apply gray threshold with morphological operation and divide the input image into different number of secret share images using traditional visual cryptography technique. Embed the each share into different cover images. Finally, stack the embedded images to get the original information of images. The performance of proposed method is calculated by using PSNR, UQI and MSE Value. The proposed EVCS shows the high performance in terms PSNR, UQI and MSE for secure transmission of bank cheque over network.
如今,银行系统已经承载了银行业务为客户的便利性、支持性服务的集合,其中身份验证起着至关重要的作用。由于黑客领域的惊人担忧和增长,依靠网络来积累所有信息是不安全的。为了解决这一问题,我们提出了一种基于嵌入式图像加密方案的安全银行支票认证算法。它是一种以视觉信息作为输入,利用人的视觉系统进行加密和解密的密码学方法。提出的嵌入式视觉加密方案(EVCS)采用灰度阈值和形态学运算实现了银行支票的网络安全传输。该方法首先将灰度阈值与形态学运算相结合,利用传统的视觉密码技术将输入图像分割成不同数量的秘密共享图像。将每个共享嵌入不同的封面图像中。最后对嵌入的图像进行叠加,得到图像的原始信息。利用PSNR、UQI和MSE值计算了该方法的性能。所提出的EVCS在PSNR、UQI和MSE方面表现出较高的性能,可用于网络上银行支票的安全传输。

Early identification of cardiovascular disease helps in treatment of heart related disease. Due to non-stationary nature of ECG and abundant recording, analysis of long term ECG recording by manual method posing great challenge. In this paper, an automatic diagnosis system is developed for detection and classification of cardiovascular disease through invariant feature extraction method. Often, ECG recording is contaminated by high frequency powerline interference and low frequency baseline wandering. Therefore, at first the recording must undergo noise removal treatment. In this study, an Adaptive denoising procedure is proposed which combines the synchrosqueezing transform and feature of wiener filter to achieve noise free recording. Then QRS complex detection followed by beat segmentation algorithm is applied for QRS beat template creation. Extraction of invariant feature from QRS beat template is proposed and such features used as input to train multiclass support vector machine for disease classification. The present study suggests that synchrosqueezing transform based diagnostic system achieves high classification accuracy.
早期发现心血管疾病有助于心脏相关疾病的治疗。由于心电的非平稳性和记录的丰富性,用人工方法对长期心电记录的分析提出了很大的挑战。本文开发了一种基于不变特征提取方法的心血管疾病自动诊断系统。高频电力线干扰和低频基线漂移往往会影响心电图的记录。因此,首先必须对录音进行去噪处理。本文提出了一种结合同步压缩变换和维纳滤波特性的自适应去噪方法,实现了无噪声记录。然后应用QRS复合体检测和节拍分割算法创建QRS节拍模板。提出了从QRS节拍模板中提取不变特征,并将这些特征作为训练多类支持向量机的输入,用于疾病分类。研究表明,基于同步压缩变换的诊断系统具有较高的分类准确率。

Compound Images are stacked with text, graphics and continuous tone contents. Screen Content Coding (SCC) improves the compression quality of images with multilayer of graphics and text that are generated by digital devices rather than camera-captured images, since these images possess repetitive patterns. We proposed an Intra-Frame Dictionary Coding based on hashing technique without modifying the HEVC syntaxes. In our proposed system the current blocks are mapped with related blocks holding the same hash value. These blocks are considered as prediction blocks and the best block is selected from the prediction blocks and encoded in a repository. Further the proposed coding efficiency can be enhanced by employing the Rate Distortion Optimization. The proposed system results when compared with the existing system displays a better performance of 95% in terms of compression ratio. The proposed algorithm is coded in MATLAB and the results were analyzed.

Nowadays, Radio Frequency (RF) Microelectromechanical system (MEMS) switches are getting more popular in the electronics field. Since consumption of power has become the highest concern in many electronics devices. The main problem for using RF MEMS switches is its high actuation voltage. Thus this paper generally concentrate on the analysis and simulation of RF MEMS metal contact switch having a n-shaped cantilever beam to obtain the low actuation voltage. Simulations are done using the finite element modelling. Intellisuite 8.7v software have been used to get the results of the switch. The design has been revised in terms of thickness of the beam and air gap to carry out electrostatic actuation mechanism. The pull-in voltage is obtained to be 2.6 V.

A low profile and highly selective dual band operation antenna in Ku band is designed for satellite communication. The proposed design is an rectangular patch with elliptical cavity. The substrate used here in the design is F4B-2 with permittivity 2.65 and thickness 1mm. Microstrip patch antennas are relatively cheaper to manufacture and require less power. The proposed FSS structure is simulated. The resonant frequencies of this design are at 14.8 and 17.2 GHz, which are very close to each other. The microstrip antenna used has increasing demand as it can be directly printed in the circuit board. HFSS Software is used to design and simulate the antenna.
