In today's world, renewable energy is the important energy source and in renewable energy "wind energy" plays vital role. Where wind turbines are placed in remote places and the operation and maintenance services (OMS) are plays key role to getting maximum availability and minimum breakdowns of wind turbine. To minimize the breakdowns in wind turbine, it is important to provide reliable and robust control system. Where communication between controllers plays key role in control system. In wind turbine, the frequency of occurrence of communication failed errors between rotating Hub and stationary Nacelle is causes of increase in breakdown in Wind Turbine. So, to implement W-CAN (Wireless Controller Area Network), where the CAN protocol gives reliable and robust communication between pitch controllers in HUB and Wireless Bluetooth over CAN protocol provide communication between Rotating hub and stationary nacelle which minimizes the communication failed errors. This system is implemented by using LPC1769, FreeRTOS, CAN (Controller Area Network), Bluetooth Protocol, LwIP (Light Weight Internet Protocol) Protocol and Motors. Today real-time communication is one of the key features in distributed embedded control systems. Using FreeRTOS, control system performance will be improved. FreeRTOS comprises CAN & LwIP protocol stack which transfer real time data from hub microcontroller node to nacelle microcontroller node. The Sensor acts as input source to this hub node and microcontroller nodes in compliance of FreeRTOS that includes the Real Time CAN driver which is used for secured and robust data transfer. Real-Time LwIP protocol stack is implemented on top of FreeRTOS to transfer the data to supervisory control and data acquisition (SCADA) System Application on Host PC. In this system, based on LwIP stack the data will be transferred from Turbine nacelle microcontroller Node to the PC Host SCADA application. SCADA application is used for data monitoring and controlling the operation. Hence with the help of this proposed system data acquisition and control of distributed embedded applications will be improved.
当今世界，可再生能源是重要的能源，而在可再生能源中“风能”起着至关重要的作用。当风力涡轮机安装在偏远地区时，操作和维护服务(OMS)对于获得最大可用性和最小故障起着关键作用。为了最大限度地减少风力发电机组的故障，提供可靠、鲁棒的控制系统至关重要。其中控制器之间的通信在控制系统中起着关键作用。在风力发电机组中，旋转轮毂与静止短舱之间通信失效错误的发生频率是风力发电机组故障增加的原因。因此，要实现W-CAN(无线控制器区域网络)，其中CAN协议在HUB和无线蓝牙之间提供可靠和鲁棒的间距控制器之间的通信，通过CAN协议提供旋转集线器和固定机舱之间的通信，从而最大限度地减少通信失败的错误。该系统采用LPC1769、FreeRTOS、CAN (Controller Area Network)、蓝牙协议、LwIP (Light Weight Internet Protocol)协议和电机实现。当今，实时通信是分布式嵌入式控制系统的关键特性之一。使用FreeRTOS，控制系统的性能将得到提高。FreeRTOS包括CAN和LwIP协议栈，将实时数据从集线器微控制器节点传输到短舱微控制器节点。传感器作为该集线器节点和微控制器节点的输入源，符合FreeRTOS，其中包括用于安全可靠数据传输的实时CAN驱动程序。实时LwIP协议栈在FreeRTOS之上实现，将数据传输到主机上的SCADA (supervisory control and data acquisition)系统应用程序。在该系统中，基于LwIP栈将数据从涡轮机舱微控制器节点传输到PC主机SCADA应用程序。SCADA应用程序用于数据监控和控制操作。因此，在该系统的帮助下，分布式嵌入式应用的数据采集和控制将得到改善。

Last two decades have witnessed tremendous work in the field of Neurocomputing. A neural network works like a distributed processor which runs parallel. A neural network consists of processing units and the attributes of these units are to acquire knowledge by the virtue of a training process and storing this experimental knowledge in synaptic weights so that it is available for future use. In the present scenario the researchers are developing Artificial Neural Networks (Single / Multilayer) for solving multidimensional problems such as pattern recognition, prediction, optimization, associative memory, control and classifier since these are identified as robust tool various applications. The conventional parameters of Neural Network are generally real numbers and these parameters are only capable to deal with real valued data. But, according to the latest scenario in the field, there is requirement of analysis of high-dimensional data. Therefore, high-dimensional neural networks like CVNN came into the existence. Due to their diversity and abundance it is now becoming difficult to represent Neural Networks in complex domain consequently they started facing representational problems.

Here in the paper, we proposed lifting scheme based non-blind hybrid image watermarking technique by utilizing low frequency band for hiding message. In proposed work, we change the singular values of the cover image with the help of embedding formula to achieve high robustness and transparency. Here, watermark is embedded into the low frequency sub-band of a cover image by using variable scaling factor. This technique is simple as compared to other in term of both insertion and extraction of the watermark in the cover image. The simulated results show the importance of proposed image watermarking scheme. This technique also tested with HVS and with the help of parameters namely peak signal noise ratio (PSNR) and normalized cross correlation (NCC).

Using Gamma-Gamma distribution to describe the atmospheric turbulences, we present a wireless optical communication model incorporating intensity modulation/direct detection (IM/DD) technique. Specifically, we have derived the closed form expressions for the cumulative distribution function (CDF) and the probability distribution function (PDF) for an FSO transmission system. Accounting for the atmospheric path losses and Mie scattering, we offer the closed form expressions for different performance parameters of wireless optical transmission system such as, outage probability, bit error rate for different binary modulation schemes and ergodic capacity, all in terms of Meijer's G function. Moreover, utilizing the asymptotic approximation of Meijer's G function, the outage probability and bit error rate are presented in the form of simple elementary functions at higher values of signal-to-noise ratio (SNR).

This paper presents result analysis of K-Mediod algorithm, implemented on Hadoop Cluster by using Map-Reduce concept. Map-Reduce are programming models which authorize the managing of huge datasets in parallel, on a large number of devices. It is especially well suited to constant or moderate changing set of data since the implementation point of a position is usually high. MapReduce is supposed to be framework of "big data". The MapReduce model authorizes for systematic and instant organizing of large scale data with a cluster of evaluate nodes. One of the primary affect in Hadoop is how to minimize the completion length (i.e., make span) of a set of MapReduce duty. For various applications like word count, grep, terasort and parallel K-Mediod Clustering Algorithm, it has been observed that as the number of node increases, execution time decreases. In this paper we verified Map Reduce applications and found as the amount of nodes increases the completion time decreases.

Metaheuristics are widely perceived optimization methods that provide optimal solutions to an expansive range of computational problems. This paper provides a survey of the quantum-inspired metaheuristics, which is a successful alternative to the classical approach for solving optimization problems and combines the principles of quantum computing and metaheuristic. The idea of employing the concept of quantum mechanics in classical computers for better working of the metaheuristic methods has been a flourishing area of research since the last few decades. This paper aims to provide details of current state-of-the-art quantum-inspired metaheuristics by explaining their working principles and the applications of it in order to do further research in this field.

It is common practice to install shunt capacitors to improve the power factor and voltage profile at all voltage levels in the power system. Almost all type of load including domestic user's appliances is inductive. Due to low water level agricultural load are also increasing. All these conditions lead to poor power factor and large amount of reactive power flows through the transmission line and voltage drop occurs. Hence, in several areas low voltage pockets are created. To improve this low power factor, adequate compensation is to be provided at load end point. Due to increasing load/consumers it is very difficult to insist every consumer to provide compensating device. Ultimately power transmission companies have decided to provide the capacitor bank at the feeding substation at various voltage levels such as 11KV, 33KV and EHV levels also. And now a day it is well accepted practice to install a capacitor bank at the feeding substation for improving the power factor of the system. The major problem with the capacitor bank is the interrupter failure i.e. the failure of circuit breaker employed for its switching. It is reported by power distribution and transmission companies that breaker failure occurs before its specified number of operation. In order to understand this problem, I thought of taking a topic of dissertation work which relates to the failure of circuit breaker employed for capacitor switching.
