In this paper, we are presenting various analyses on master slave D Flip-Flop which is designed using FinFET. Master Slave Flip-Flop is advanced version of Flip-flops. To make Master Slave Flip-Flop Normal Flip-Flop is followed by Clocked S-R Flip-Flop. According to Moore's law the no. of transistor in a meticulous chip area is two times in every 18 months. This announcement gives new age of VLSI meadow. If we want to increase the no. of component in chip area so we diminish the size of component. Appling this quality in chip component, the size of transistor reduced. As we scale down the device parameter after a certain rule, the short channel effects like leakage power, surface scattering, velocity saturations, takes place. Fin-FET is a superior device to eliminate or decrease above mentioned problems. We evaluate the various parameters like temperature effect to the total power, total power consumption, average DC power, calculation etc. For calculation of these results we are use cadence tools. After simulating the circuit we get values of Average DC power which is 160nW, Instantaneous Transient Power Consumption is 65.20nW, Delay is 30nS.
本文介绍了利用FinFET设计的主从D触发器的各种分析。主从触发器是触发器的高级版本。为了使主从触发器正常触发器之后是时钟S-R触发器。根据摩尔定律。每18个月就会有两次晶体管在一个精密的芯片区域发生故障。这一公告标志着VLSI领域进入了一个新的时代。如果我们想增加no。在芯片面积上减小元件的尺寸。将这种品质应用于芯片元件,晶体管的尺寸减小了。当我们按一定规律缩小器件参数时,会出现漏功率、表面散射、速度饱和等短通道效应。翅片场效应管是消除或减少上述问题的优良器件。我们评估了温度对总功率、总功耗、平均直流功率、计算等各种参数的影响。为了计算这些结果,我们使用节奏工具。通过对电路的仿真,得到平均直流功率为160nW,瞬时暂态功耗为65.20nW,延时为30nS。

This paper presents a photovoltaic (PV) supported single-phase voltage source inverter (VSI) based series controller for compensation of voltage sag/swell in the distribution system. The control scheme is based on phase advance compensation technique used for the series controller. Using this technique the series controller not only compensates the voltage sag/swell but also controls the flow of power in the grid. The PV supported series controller also include DC-DC boost converter for maximum power point tracking (MPPT) and supports the dc link voltage of the VSL The proposed controller successfully controls the flow of power to the grid depending upon the availability of power from the PV system and requirement by the load. Simultaneously it also compensates the sag or swell in the distribution system. The simulation results using PSCAD/EMTDC 4.2 are presented to verify the performance of the proposed series controller.

Wireless sensor network is a diverse network. One of the important limitation of the wireless sensor network is limited life-time, wireless nodes typically operates with small batteries for which replacement, when possible, is very difficult and expensive. Therefore nodes must operate without battery replacement for long time. Consequently, minimizing the energy consumption is a very important design consideration and energy-efficient transmission schemes must be used for the data transfer in wireless sensor networks. This paper, proposes the energy efficient transmission scheme to minimize the per node energy consumption. In the proposed scheme after the cluster formation in the network potential cluster head will select the cooperative node to transfer data from one cluster to other. The results shows that by transmitting and/or receiving information jointly, tremendous energy saving is possible for larger transmission distances, even after considering the local energy cost necessary for joint information transmission and reception.
无线传感器网络是一个多样化的网络。无线传感器网络的一个重要限制是有限的寿命,无线节点通常使用小电池运行,如果可能的话,更换电池非常困难和昂贵。因此,节点必须长时间不更换电池。因此,在无线传感器网络中,最大限度地减少能量消耗是一个非常重要的设计考虑因素,必须采用节能的传输方案来进行数据传输。本文提出了一种以节点能耗最小为目标的高效传输方案。在提出的方案中,网络中集群形成后,潜在的集群头将选择合作节点从一个集群向另一个集群传输数据。结果表明,即使考虑到联合信息传输和接收所需的局部能源成本,通过联合发送和/或接收信息,可以在更大的传输距离下节省大量的能源。

This paper presents an effective methodology to optimally reconfigure an electrical distribution network. Selective Particle Swarm Optimization (SPSO) algorithm is proposed to find the optimal combination of switches that results in a radial configuration with minimum system power loss. SPSO is a modified Binary Particle Swarm Optimization (BPSO) with selective search space. Comparative analysis of SPSO with BPSO for network reconfiguration, under four different loading conditions, namely base, light, medium and heavy, on IEEE 69 bus system is presented to demonstrate the suitability of the proposed method. It is observed that SPSO outperforms BPSO in terms of quality of solution, voltage profile, convergence characteristics and time elapsed to complete optimization process.

In modern communication system error-correction coding pattern boosts sufficient redundancy which in turn upsurges the immunity to pact with the channel impairments. Turbo code can deliver restrained progress in BER performance in an AWGN channel by varying interleaver size and free distance. In this paper, an optimized Parallel Concatenated Convolution Turbo code has been proposed to improve BER performance ominously. The identical Recursive Systematic Convolutional (RSC) encoder has been used to prove the enhancement in BER performance. The simulation result shows that the proposed Harmony-Search (HS) optimized Parallel Concatenated Convolution Turbo code is superior in performance to the conventional Parallel Concatenated Convolution Turbo Code.

Many plants are facing the risk of extinction due to unplanned urbanization and over growth of population. Digital databases of plants should be maintained for proper tracking of local flora and making data-driven policies/decisions for their preservation. Plant identification is important for medical as well as educational purposes but maintaining an exhaustive digital database is a challenging task due to the presence of large number of plant species. This paper proposes a system for building a digital database of local flora and recognizing different plants using their leaf images. The system proposed in this paper involves four steps: 1) image acquisition, 2) image preprocessing, 3) feature extraction, and 4) classification. Images are acquired using commonly available general purpose desktop scanner with white paper as a background. In the image-preprocessing module, the system applies several image-processing techniques to prepare a leaf image for the feature extraction process. Then twelve leaf-shape based features are estimated and IBI classifier is used to classify the plant species. The proposed system was used to build a dataset of local flora of Uttarakhand region, consisting of 1684 images of thirty-two different plant species. The database contains around fifty leaves of each plant species. The proposed system gives promising results with an average classification accuracy of 79% for these thirty species of plants.
由于无计划的城市化和人口的过度增长,许多植物正面临灭绝的危险。应保持植物的数字数据库,以便适当地跟踪当地植物区系,并根据数据制定保护它们的政策/决策。植物鉴定对于医学和教育目的都很重要,但由于存在大量植物物种,维护一个详尽的数字数据库是一项具有挑战性的任务。本文提出了一种利用植物叶片图像建立本地植物区系数字数据库并识别不同植物的系统。本文提出的系统包括四个步骤:1)图像采集,2)图像预处理,3)特征提取,4)分类。图像是使用常用的通用桌面扫描仪以白纸为背景获取的。在图像预处理模块中,系统应用了多种图像处理技术,为特征提取过程准备叶片图像。然后估计出12个基于叶片形状的特征,并使用IBI分类器对植物进行分类。利用该系统建立了Uttarakhand地区植物区系数据集,该数据集包含32种不同植物的1684张图像。该数据库包含每种植物的大约50片叶子。该系统对这30种植物的平均分类准确率为79%,结果令人满意。

In this paper a novel low-voltage and low-power rail-to-rail linear operational transconductance amplifier (OTA), operating in sub-threshold region is presented. The source degenerated bulk-driven input stage ensures rail-to-rail operation with enhanced linearity. To enhance its transconductance and current drive capability a regenerative feedback at input transistor's gates has been employed. The OTA operating at 0.5 V supply ensured total harmonic distortion (THD) <; -40 dB. The circuit provides 43 dB gain and 90 kHz gain bandwidth product. The Tanner EDA 15.0 simulation tool environment using 0.18 μm CMOS process technology has been used to simulate the proposed circuit. Simulation results show that with supply of one threshold order, circuit consumes 292 nA current and 146 nW power and exhibits less than -65 dB total harmonic distortions, for 100 mV(p-p) signal at 200 Hz frequency in its unity gain configuration.
