These techniques are evaluated in presence of low SNR noises (i. e. f16, babble, white, and pink). The noise estimation techniques have major impact on the quality and intelligibility of denoised speech pattern. The noise estimation techniques are evaluated in frequency domain in terms of quality and intelligibility measure parameters. The Perceptual Evaluation of Speech Quality (PESQ), Weighted Spectral Slop metric (WSS), Frequency Weighted Segmental SNR (fw-SNRseg), Speech Intelligibility Index (SII), and output SNR parameters are used for performance evaluation of low SNR noises mixed speech patterns. The sampling frequency used for processing is 8000 Hz and all algorithms are implemented in MATLAB 7.14.","PeriodicalId":355706,"journal":{"name":"International Conference on Recent Advances and Innovations in Engineering (ICRAIE-2014)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123983646","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}

The proposed EDC technique is aimed to identify the relevant and irrelevant instance from the large data set through the degree of the missing value, and it reconstructs the missed value in relevant instance through its closest instance within the instance set. The EDC technique is consist of two methods Identify Relevant Instance (IRI) and Reconstruct Missing Value (RMV). The IRI method is identifying the relevant and irrelevant instance belongs to the large instance set through the degree of the missing value of each instance in the instance set, and the RMV method can reconstruct the missing value in the relevant instance through its closest instance based on the distance metric. Experiment result shows, that the proposed EDC technique is simple and effective for identifying the relevant and irrelevant instance, and reconstruct the missing values in the relevant instance through the closest instance with higher similarity.","PeriodicalId":355706,"journal":{"name":"International Conference on Recent Advances and Innovations in Engineering (ICRAIE-2014)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121184627","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}

But no simulator is currently available. This paper Implementation of Optimized Commit Protocol (IOCP) is an effort to allow simulating the performance of O-2PC empirically to consider the indirect costs that is not possible to calculate analytically.

The purpose of data hiding in medical image is to embed the patient information in the host medical image without perceptually distorting it. This paper proposes a novel approach in embedding Patient information and Electrocardiogram (Patient Data) which is encrypted to ensure greater security in spatial domain. Statistical parameters such as Normalized Root Mean Square Error and Peak Signal to Noise Ratio are used to measure the quality of the medical image with patient data. Experimental results strongly indicate that the present technique is found to be robust and embedded patient data is recoverable without any distortion even in the case of attack like Gaussian noise.","PeriodicalId":355706,"journal":{"name":"International Conference on Recent Advances and Innovations in Engineering (ICRAIE-2014)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127616175","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}

In this paper we point out three serious weaknesses namely, lack of scalability, high memory requirementsand computational overhead for designing pair-wise key agreement between any pair of sensor nodes in a WSN proposed by Chien et al. [1]. We develop a new scheme based on Blom's key agreement protocol [2] which is free from the weaknesses mentioned above. Compared to [1],our scheme requires less memory ,less computational overheads and more secure accesses to the network.

The proposed antenna design includes a metallic rings around the metal patch, initially at a distance of the one-quarter of the free space wavelength from the edges of patch and width of metallic ring is three times of one-sixteen of the free space wavelength. Using CST Microwave studio, the results of the patch antenna without metallic rings and patch surrounded by metallic rings are simulated and compared. The proposed microstrip patch antenna resonates at the 5.8 GHz frequency suitable for wireless local area network applications. By this metallic rings approach there is enhancement in the gain of microstrip patch antenna about 4.3 dB as compared to conventional one (without metallic rings) and also about 2 percent improvement in impedance bandwidth of proposed antenna as compare to antenna without metallic ring.","PeriodicalId":355706,"journal":{"name":"International Conference on Recent Advances and Innovations in Engineering (ICRAIE-2014)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126549726","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}

Various authors have proposed different schema evolution operators for various level updates but none of them handled the syntactic and semantic adaptation of queries automatically. Few authors discussed this problem considering few changes in data sources schema and data warehouse structure schema. But they did not deal with the problem due to changes in the hierarchy and its levels in a dimension of the schema. In this paper, we perform what-if analysis for change in the hierarchy and its levels in the data warehouse schema. Queries, views and relations are modeled in a graph annotated with policies to manage the change event.

This paper proposes a new approach of image steganography which uses two secret keys to randomize the bit hiding process. Use of two secret keys enhances the security of secret information. This approach uses red, green and blue values of a pixel and performs some calculation. Based on this calculation, secret information bits will be placed at the random position of the pixels. This approach maintains high data hiding capacity like LSB substitution but maintains a much better security level, which is not present in LSB substitution as LSB substitution technique is predictable. As the hidden information is highly randomized, so it is difficult for attacker to retrieve the secret information from stego image. I used PSNR value to determine the quality of stego image and also compare it with other efficient image steganography techniques. The obtained result showed that this algorithm is highly efficient as compared to many other techniques.","PeriodicalId":355706,"journal":{"name":"International Conference on Recent Advances and Innovations in Engineering (ICRAIE-2014)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121759707","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}
