In this paper, the authors propose a new ECG compression algorithm which embeds patient's identification inside the ECG data. The compressed file contains only ASCII characters. The proposed scheme also allows the decompression technique where the original ECG waveform can be exactly reconstructed and retrieve patient's identification from the ECG signal. The whole module has been applied to various ECG data of all the 12 leads taken from PTB diagnostic database (PTB-DB) of physioNet (www.physionet.org) and gives a highly compressed result that can be stored using far less digital space without distorting important ECG characteristics which are essential for proper medical diagnosis. Moreover, the compression, embedding, decompression and retrieving of data are achieved in a series of sequential, simplistic logical processes that can be easily executed. It is observed that the proposed algorithm gives a high compression ratio (CR=7.3593, an excellent Quality Score (QS=1362) and very low difference between original and reconstructed ECG signal (PRD=O.0054).

In this paper, a method to improve the sensitivity of the resonance mass sensor by incorporating PID controller is proposed. The controller is designed to retain the vibrating frequency of the resonator at its natural frequency with mass loading. The experimental results demonstrate that the resonant mass sensor with PID controller provides 18 times higher sensitivity as compared to the resonant mass sensor without controller.

Error concealment techniques try to mitigate the effect of channel error, using spatially and/or temporally neighboring macroblocks. This paper proposes a novel method for temporal error concealment. The change from one frame to the next frame is modelled as an affine transformation and Speeded Up Robust Features (SURF) algorithm is used to find correspondence between present and past frame. The set of matching points between the two frames is used to find an affine transformation. Random Sample and Consensus (RANSAC) algorithm is used to effectively remove outliers. The past frame is then affine transformed using the transformation matrix obtained. Corrupted regions are concealed using Temporal Replacement (TR) in the current frame with the transformed past frame as reference. Experimental results established the efficacy of the proposed algorithm over other temporal error concealment scheme in terms of both objective and subjective measurements.
错误隐藏技术试图通过使用空间和/或时间上相邻的宏块来减轻信道错误的影响。提出了一种新的时间误差隐藏方法。从一帧到下一帧的变化被建模为仿射变换，并使用加速鲁棒特征(SURF)算法来寻找当前帧和过去帧之间的对应关系。利用两帧之间的匹配点集来求仿射变换。采用RANSAC (Random Sample and Consensus)算法有效地去除异常值。然后利用得到的变换矩阵对过去坐标系进行仿射变换。以变换后的过去帧为参考，在当前帧中使用时间替换(TR)来隐藏损坏的区域。实验结果表明，该算法在客观和主观测量方面都优于其他时间误差隐藏方案。

This paper presents a simple and low cost scheme for closed loop operation of MEMS capacitive accelerometer. The in-house developed accelerometer consists of a Silicon on Insulator (SOI) based comb drive structure integrated on a PCB with capacitance signal conditioning ASIC. A simple PI type controller designed using basic components like resistors, capacitors and op-amps are externally incorporated. The self test arrangement in MEMS structure has been successfully utilized for applying feedback voltage to operate the device in a closed loop configuration. The proposed scheme is shown to be a simple and cost effective approach for driving similar open loop MEMS accelerometers in a closed loop configuration. Further, the experimental results for both open loop and closed loop arrangement are shown to agree well with their corresponding simulated responses.

Superconducting Fault Current Limiters (SFCLs) are used in power system network to mitigate the overcurrent and its prominent effects. Nowadays, Coated Conductors (CCs) are widely used for novel design of SFCL for such applications. In this paper, comparative study on the operational characteristics of Resistive-SFCL based on BSCCO and YBCO Coated Conductors under fault condition is analyzed for an 110kV/9kA network. Also Electro-thermal Model of Coated Conductor is studied in MATLAB software. To verify the effectiveness of the proposed Resistive-SFCL, several case studies of Coated Conductors have been carried out in MATLAB. The results show the choice of optimal configuration of CCs as SFCL which effectively improves the thermal stability and current limiting characteristics under fault condition in the network.

The frequency response of a microwave notch filter using a pair of magic tees has been studied theoretically as well as experimentally in this paper. This notch filter designed at 10.5 GHz eliminates the first interfering tone. When the second interference appears at the input of this notch filter the response is modified and its fails to remove the first interference because the null point of the response gets shifted upwards under the action of the second interference. The dc shift of the minimum of the response has been calculated and measured when the second interference is 520 MHz below the first interference. The theory and experiment gives a reasonable fit.

Anomaly detection has drawn a slew of attention in recent years, although term has been known as outlier detection in statistics several decades ago. Everyday large volume of data is being generated. For example, flight navigation data, health care monitoring data, social media data, video surveillance data etc. This data contains rare events or anomalous points that needs to be found out-for example less than 2 % of all visitors who visits Amazon website make a purchase. Thus anomaly detection problem can be interesting due to business perspective, security, maintenance etc. The problem becomes challenging because of noise, heterogeneity, high dimensionality of the data. This paper studies a robust algorithm, based on support vector data description, for anomaly detection. We perform extensive experiments on real data coming from nuclear power plant to empirically demonstrate the effectiveness of the algorithm as well as finding anomalies in the data set. We also discuss extensions of the algorithm to find anomalies in high dimension and non linearly separable data.

Rapid growth in the field of ICT helps in basic aspects of mankind like-agriculture, education, healthcare etc. However, the moderate technical growth of ICT applications is confined to the community of a limited number of people, who live in digital pockets. The illiterate people like - farmer, shopkeeper etc. are unable to take the advantages of the ICT revolution. According to the UNESCO report, population of such people in the globe is 64% who are unable to use the technology either language or technical barrier. Moreover the percentage (76%) must be increased in the context of developing countries. The essential agriculture information is very useful to a farmer for taking effective decision thus we proposed to develop an iconic interface which is integrated with speech based interaction in Indian languages. The proposed interface is critically evaluated with the farmer from different states of India. The evaluation results proved the effectiveness of the proposed interface.

In entity name disambiguation technique, records of same entity are clustered together. One of the major challenges in such technique is to validate the result as the actual or correct results are often not known or difficult to know. In this context, three commonly known evaluation measures are precision, recall and f-measure. All these indices are external validity indices as they all need gold standard data. But in Bibliographic databases like DBLP, Arnetminer, Scopus, Web of Science etc., obtaining golden standard is very difficult for each entity. So, there is a need to use some other metrics to evaluate the performance on Bibliographic data. In this paper, a novel scheme based on internal validity index is used to evaluate the performance of entity name disambiguation algorithm. Several distance measures are used here to compute the similarity between two records. These functions are then incorporated in the definitions of internal validity indices.

Winding deformation in power transformers affects its mechanical integrity. Diagnosis of winding deformation is a necessary step towards preventing its permanent failure. Sweep Frequency Response Analysis (SFRA) is widely used to analyze the nature and extent of deformation. However, the location of deformation needs the signature from the deformed transformer at various locations, which is practically not feasible. In this paper, Finite Element Method (FEM) and SFRA are used to model deformations on a benchmark winding and obtain corresponding signatures. Different parameters derived from SFRA are used as indices to distinguish type and location of deformations.
