Self excited induction generators are preferred to be one of the best machines for generation of electricity in remote and rural areas due to its capability of generating electricity without any external source. But on the other hand it is also a challenging task to maintain its voltage and frequency under load varying condition. In this paper we have considered a micro grid system with a Self excited induction generator and doubly fed induction generator as the source of generation connected by a transmission line. The Self excited induction generator is employed in a micro-hydro generation system where as the doubly fed induction generator is used for power conversion in a wind energy conversion system. A STATCOM with battery energy storage system is connected to the load bus acting as a compensator of active and reactive power, maintaining the voltage and frequency of system constant under different loading conditions such as linear load, nonlinear load and dynamic load. Sliding mode controller is used to control the STATCOM in a purpose to generate desired active and reactive power. The above system is modeled and simulated in MATLAB/SIMULINK and results are presented.

In mobile ad hoc networks (MANETs), authentication is a critical issue. It is a tough task to provide security and authentication in MANETs due to the absence of any centralized administration and dynamic topology of the network. This paper presents a robust and secure mechanism for authentication of nodes in the MANET. The proposed authentication protocol is based on certificate exchange between the nodes. This protocol also uses digital signature with a hash function to maintain the authenticity of certificates. Simulation shows that this protocol shows better performance in terms of throughput, end-to-end delay and packet dropping in presence of malicious nodes in the MANET. In addition, it also has less computation and communication overhead, which makes it suitable for MANETs.
在移动自组织网络(manet)中,身份验证是一个关键问题。由于缺乏任何集中管理和网络的动态拓扑结构,在manet中提供安全性和身份验证是一项艰巨的任务。提出了一种可靠、安全的无线局域网节点认证机制。提出的认证协议基于节点间的证书交换。该协议还使用带有哈希函数的数字签名来维护证书的真实性。仿真结果表明,在恶意节点存在的情况下,该协议在吞吐量、端到端延迟和丢包等方面都有较好的性能。此外,它还具有较小的计算和通信开销,使其适合于manet。

The intent of this paper is to track the height of a tidal wave, using the Kalman filter. By using the Kalman filter algorithm, mathematical expressions are derived to determine the height of a tidal wave. By placing buoy sensors at specific locations in the sea, the real tidal wave height is measured. The buoy sensor is placed at a particular distance from the shore. The sensors continuously record data at that particular position at different time intervals and then transmit the data to the receiver on the shoreline. By continuously evaluating this data, the height of the next wave is being estimated. Since a buoy cannot be placed at every point of the wave, this method provides an easy estimation of replicating the process. These sensors are used to simulate the proposed method of tracking the height of a tidal wave and hence giving a warning in advance in case of a wave height which is more than normal. This warning helps people living in coastal areas to vacate the place in advance, therefore avoiding fatality. This tracking of the tidal wave height is useful particularly in the case of a tsunami. By adding Gaussian white noise to the input data from the buoy sensors, a prediction of the next wave height is possible.
本文的目的是利用卡尔曼滤波来跟踪潮汐波的高度。利用卡尔曼滤波算法,导出了确定潮汐波高度的数学表达式。通过在海上的特定位置放置浮标传感器,可以测量真实的潮汐波高。浮标传感器被放置在离海岸一定距离的地方。传感器以不同的时间间隔连续记录特定位置的数据,然后将数据传输到海岸线上的接收器。通过不断地评估这些数据,就可以估计出下一波的高度。由于浮标不能放置在波浪的每个点,这种方法提供了一个简单的估计复制的过程。这些传感器用来模拟所提出的跟踪潮汐高度的方法,从而在波浪高度超过正常水平时提前发出警告。这一警告有助于居住在沿海地区的人们提前撤离,从而避免死亡。这种对潮汐波高度的跟踪是有用的,特别是在海啸的情况下。通过在浮标传感器的输入数据中加入高斯白噪声,可以预测下一波的高度。

FinFETs are considered to be one of the promising devices to extend the CMOS technology beyond the scaling limit of conventional CMOS technology. FinFETs mass manufacturing has been made successfully on bulk and on silicon-on-insulator (SOI) wafers. Additional processes are needed to suppress the leakage current in the case of bulk. In this paper, stack gate technique to suppress the leakage current is proposed with a gate length of 10nm and the performance characteristics are analyzed through ON current, OFF current, Ion/Ioff ratio, DIBL (Drain Induced Barrier Lowering), and SS (subthreshold slope) through 3-D TCAD simulation, metal gates are shown to be feasible. A comparison of both vertically stacked gate and horizontally stacked gates has also been presented.

The use of digital applications is on the rise nowadays. So the processing of those data is done by a tool calledMapReduce. MapReduce has its own structure which cannot be modified. While processing those data, skew will occur in both map and reduce the phase. Map skew is easy to reduce but in case of reduced phase it may take time to reduce it. So a methodology is being created to reduce the Reducer side skew and time being compared between the new method and MapReduce to find their efficiency.
如今,数字应用程序的使用呈上升趋势。所以这些数据的处理是由一个叫做mapreduce的工具完成的。MapReduce有自己的结构,不能修改。在处理这些数据时,map和reduce阶段都会出现倾斜。地图倾斜很容易减少,但在减少相位的情况下,可能需要时间来减少它。因此,我们正在创建一种方法来减少Reducer的侧斜,并将新方法与MapReduce之间的时间进行比较,以找出它们的效率。

Protection of digital content from being tapped by intruders is a crucial task in the present generation of Internet world. In this paper, we proposed an implementation of new visual secret sharing scheme for gray level images using diamond theorem correlation. A secret image has broken into 4 × 4 non overlapped blocks and patterns of diamond theorem are applied sequentially to ensure the secure image transmission. Separate diamond patterns are utilized to share the blocks of both odd and even sectors. Finally, the numerical results show that a novel secret shares are generated by using diamond theorem correlations. Histogram representations demonstrate the novelty of the proposed visual secret sharing scheme.

Even today, a large number of organizations collect data using paper forms. However, it can be difficult to aggregate, and analyze the data collected using paper forms. Better management and processing of forms and applications is indispensable to improving customer experience. But, typing the form data into a spreadsheet is time-consuming, mundane and may result in errors. Various attempts have been made to automate the process but the solutions require the use of expensive specialized hardware. This paper presents ACE, a system that uses computer vision and mobile imaging technology to capture data from any paper form using inexpensive and readily available smartphones. ACE is not restricted to a specific type of form, it is designed to dynamically adapt to any type of paper form presented to it. It generates template of the form, which the user wishes to extract data from. Later, this template is used to extract data from the filled form. The extracted data from filled forms is stored in a structured format, exportable as a CSV file.

This paper frames co-relation on three feature extraction techniques in ASR system. As compared to primarily used technique called MFCC (Mel Frequency Cepstral Coefficients), PNCC (Power Normalized Cepstral Coefficients) obtains impressive advancement in noisy speech recognition due of its inhibition in high frequency spectrum for human voice. The techniques differ in the way as MFCC uses traditional log nonlinearity and PNCC processing substitute the usage of power-law nonlinearity. Experimental results relay on the fact that PNCC processing provides substantial improvements in recognition accuracy compared to MFCC as well as PLP (Perceptual Linear Prediction) processing for speech recognition in the existence of various types of additive noise and reverberant environments with marginally greater computational cost and the with the usage of clean speech, it does not lowers the decoding accuracy.
本文对ASR系统中三种特征提取技术的相互关系进行了分析。与主要使用的MFCC (Mel频率倒谱系数)技术相比,PNCC(功率归一化倒谱系数)由于其对人类语音高频频谱的抑制作用,在噪声语音识别方面取得了令人印象深刻的进步。技术的不同之处在于,MFCC使用传统的对数非线性,而PNCC处理替代了幂律非线性的使用。实验结果表明,在存在各种类型的加性噪声和混响环境的情况下,与MFCC和PLP(感知线性预测)处理相比,PNCC处理在识别精度方面提供了实质性的提高,计算成本略微增加,并且使用干净语音时,它不会降低解码精度。

In several kinds of equipment, it is essential to produce the accurate waveforms under various frequencies and profiles such as agile frequency source. Also it should have low phase noise, low spurious signal content for communication in various applications. Direct Digital Synthesizer [DDS] can provide more significant advantages using the PLL approaches such as continuous phase switching response, fine tuning the frequency resolution, settling time speedily, and reducing the noise. These are the features which help to obtain a good DDS system. The main motto of this paper is to describe about a DDS circuit structure and design a better DDS in detail.
本文的主要目的是建立一种合成多通道正弦波和方波的新方法。在多种设备中,需要在各种频率和波形(如捷变频源)下产生准确的波形。同时还应具有低相位噪声、低杂散信号含量等特点,适用于各种通信场合。直接数字合成器(Direct Digital Synthesizer [DDS])采用锁相环(PLL)方法可以提供更显著的优势,如连续的相开关响应、精细的频率分辨率、快速的稳定时间和降低噪声。这些都有助于获得一个好的DDS系统。本文的主旨是详细描述DDS的电路结构,并设计出一个更好的DDS。
