In three dimensional (3D) space vector pulse width modulation (SVPWM) applications, a defined overall 3D space is required within which the control signal vector has to be mapped. This overall space is called the active space and is obtained with vector representations of all valid switching states (SS) of the converter that has to be modulated. The vector representations of all valid SS are obtained from the Clarke transformation of terminal voltages obtained at ac terminals of the converter for respective switching states. In this paper simple alternative method has been presented to find α, β & γ components for a given SS. It can produce exactly same results as those computed by Clarke transformation. Application of the proposed formula does not need prior knowledge of Clarke transformation or converter's ac terminal voltages for different switching states.

In the electricity pricing, the congestion management has become extremely important and it can impose unavoidable problems in electricity trading. In this paper, Gravitational Search Algorithm (GSA) based optimization is performed to address the optimal power flow (OPF) problem governed by contribution factor based ranking and nodal congestion price based ranking in order to achieve congestion relief and maximum economic benefit with desired voltage level and minimum system loss. The methodology has been tested on a typical IEEE test system.

This paper deals with inverters which are to be synchronized to share the common load of microgrid. The microgrid under consideration is in OFF grid condition and hence one of the inverters is designed as master and the remaining are designed for slave mode of operation. A state-of-the-art synchronization strategy is developed for the initial synchronization of the inverter during startup period. The microgrid synchronism is then maintained with this master-slave configuration of inverters and the amount of load that can be fed to the microgrid, is adjusted or decided by the user. The control strategy is so designed that the load can always be fed at unity power factor. The SPWM technique and an output filter are utilized to reduce the voltage harmonics to a minimum level and thus produce an almost sinusoidal terminal voltage. The entire design is simulated with MATLAB Simulink and the desired output is achieved.

在处理图像的应用中，广泛使用的方法(称为增强对比度)是均衡化直方图。这方面的算法可以毫不费力地执行;即使这样，它也有将图像亮度变形到灰度尺度中心点的倾向。本文档展示了直方图的修改方案，该方案是基本的，可以根据实现的特性来处理此类问题。发现了直方图的两个支持量的边界估计，并分别定位到相关的质量。然后通过枚举概率密度函数来计算图像的概率，并利用映射修正函数来实现HE。实验结果表明，所提出的方法可以有效地提高由HE和HM例程改进的图像标准，甚至称为直方图再分布的HR，例如灰度(GLG)分组，RGB颜色间距和色调保持方法。分别取R G B分量，重新映射。

In this paper, six different grades of Assam CTC black tea liquor were discriminated by means of cyclic voltammetry. A 3-electrode configuration was used to study the voltammogram where Polyacrylamide/Exfoliated Graphite composite (PAM/EGC) was used as the working electrode. Data obtained from the tea samples were subjected to multivariate data analysis techniques viz. Radar plot, Box plot and Principal Component Analysis (PCA). The results were found quite promising, thus justifying the suitability of the prepared working electrode for the quality estimation of tea.

Outdoor image and video corrupt easily owing to fog, mist etc. Several techniques have been proposed to overcome these problems. But there is no optimum method as these scenarios are unpredictable and all situations are unique in their own way. Dark channel prior - a new prior-gives a significant prediction about the quantity of airlight that causes haze. Dark channel with contrast controller and sky masking improves the visibility with significantly reduced time. In this paper a innovative technique has been studied and it's qualitative and quantitative analysis carried out.

This study focuses on the issue of position tracking of a budgeted electrohydraulic system with the aid of marker based visual sensing of the actuator rod position using a single camera. The system comprises of a single-rod cylinder having non-linear friction characteristics and industry grade proportional valve possessing a large-deadband. A controller has been developed based on an input linearized system model involving the combination of a sliding mode and a deadband controller. An adaptive strategy for the controller parameters relying on a Lyapunov function has been introduced to handle the nonlinearities and uncertainties involved in the system. The controller demonstrated satisfactory performance for the realtime experiments conducted on the laboratory scale system.

Deregulation of electric power system has brought complexity in the system, competition among the electricity sellers and buyers which further creates overloading in transmission lines. Congestion occurs when undesirable transaction occurs through transmission lines during the transportation of electricity from generation to load centre. It is the duty of Independent System Operator (ISO) to ensure secure, reliable electricity transaction while facing the transmission congestion threat. This article presents a well known congestion management methodology i.e. rescheduling of generator output power in deregulated electricity market. In this work, firstly generator sensitivity factor (GSF) is calculated and based on these GSF values few generators are selected to reschedule their output for congestion management. A new meta-heuristic algorithm i.e. Flower Pollination Algorithm (FPA) has been adopted to reduce the generator rescheduling cost. The proposed work is verified on IEEE 39 bus New England system.

The control of air vehicles is a very challenging task due to the presence of high nonlinearity and coupling between different elements. Twin Rotor MIMO System (TRMS) kit is a prototype of a helicopter designed for conducting laboratory experiments. The most common and simplest technique is to use a PID controller for the design process. Here in this paper we propose a simple design and implementation of an I-PD controller. We compare the results obtained from PID controller and I-PD controller and the results are found to be more satisfactory in case of I-PD controller. Further this scheme satisfies the robust condition of the plant.
