Optical character recognition in the video document or videos from is a challenging task because flipping in the unconstrained environment and at any speed can cause difficulties specially in selecting a frame that contains the required image (OBI) for readability. In this paper, we stress on the problem of recognizing the readable and whole frame by selecting the frames with optical flow. Fundamentally, optical flow is used here for segmentation of the required area from the frame. Due to the unavailability of such a dataset, we have also created a dataset of video document containing book-flipping videos. Experiments are executed on the sample video documents recorded using mobile camera. The use of optical flow on video document gives proper track of motion as it detects the boundary of the document. Here in this case a normal Indian publication textbook is used. The need to develop this technique is to help various educational reforms in Indian universities related to paper evaluation. A light-weight model and accurate results makes this technique is cost-efficient and sustainable.
视频文档或视频中的光学字符识别是一项具有挑战性的任务,因为在不受约束的环境中以任何速度翻转都会导致困难,特别是在选择包含所需图像(OBI)的帧以提高可读性方面。本文重点研究了通过选择具有光流的帧来识别可读帧和整帧的问题。基本上,光流在这里用于从框架中分割所需区域。由于这样的数据集不可用,我们也创建了一个包含翻书视频的视频文档数据集。对移动摄像机拍摄的样本视频文件进行了实验。光流在视频文件上的应用,在检测文件边界的同时,提供了正确的运动轨迹。在这种情况下,使用的是普通的印度出版教科书。开发这种技术的必要性是为了帮助印度大学进行与论文评价有关的各种教育改革。该方法模型轻巧,结果准确,具有成本效益和可持续性。

This paper illustrates the performance assessment and design of CMOS Two Stage OTA under 130nm and 180nm technology nodes focusing on optimization in compensation capacitance, reduction in power dissipation. The designed circuit operates at two different supply voltages of 1.2V and 1.8V and the input relay is dependent on bias current. In this paper, the device parameters such as AC-Gain, Phase margin, Slew rate, CMRR, ICMR, Output offset voltage, Gain bandwidth, Noise and Power dissipation are theoretically calculated and analysed using LT spice software for 130nm and 180nm technology for given specifications. As the power is a major design parameter, the bias current and supply voltage is varied within the range of respective technology nodes to achieve a minimum power dissipation design. For minimum power design, reduction in bandwidth and stability of the system are major trade-offs. The designed circuit uses a specific compensation methodology for implementing the compensation called Miller compensation. It is used for improving the bandwidth and slew rate of the designed system for various capacitive loads.
本文阐述了CMOS两级OTA在130nm和180nm技术节点下的性能评估和设计,重点是优化补偿电容,降低功耗。设计的电路工作在1.2V和1.8V两种不同的电源电压下,输入继电器依赖于偏置电流。本文利用LT spice软件对给定规格下130nm和180nm工艺的交流增益、相位裕度、摆率、CMRR、ICMR、输出偏置电压、增益带宽、噪声和功耗等器件参数进行了理论计算和分析。由于功率是主要的设计参数,因此偏置电流和电源电压在各自的技术节点范围内变化,以实现最小的功耗设计。对于最小功耗设计,带宽的减少和系统的稳定性是主要的权衡。所设计的电路采用了一种特殊的补偿方法来实现米勒补偿。它用于提高所设计系统的带宽和摆幅率,以适应各种容性负载。

In remote areas the cost of transmission of electrical power to the load from the main grid is very huge which increases the per unit cost of electricity. Moreover the regular damage to the transmission lines due to the natural phenomenon's affects the power supply. In addition to this the malfunctioning of the grid can also affect the power supply. Hence, in such cases our local generating stations can be utilised for meeting up the local demand. The use of local generating stations in unison with main grid forms a microgrid which increase the reliability and ensure continuity of the supply. In this work operation of the solar photovoltaic (SPV) system based 200kWp microgrid operated in grid linked mode has been analysed. The active power of system is regulated by an active power regulating strategy. For the analysis, the system has been modelled in MATLAB/Simulink. The system comprised of two SPV plants connected to a grid and the capacity of each SPV plant is 100kWp. The perturbation and observation based MPPT algorithm has been used for maximal power tracking from the SPV plants. In the control scheme voltage from grid and current from the inverter are transformed to dq0 coordinates and active (P) and reactive (Q) power are enumerated. The calculated P & Q are compared to Preference and Qreference, respectively. The transformed voltages and currents are also added. After this PWM generator generates the triggering pulses for inverter switches. The control strategy operates in two control loops, an outer power control loop and inner current control loop. A PLL is also used to match the phase and frequency of inverter output with the grid voltages. The obtained results shows the tracking of the peak power from the SPV for every value of irradiance and temperature inputs. The results also show that by using the control strategy the active power fed to grid can be properly controlled and can be changed to any reference value.
在偏远地区,从主电网向负荷输送电力的成本非常高,这增加了单位电力成本。此外,由于自然现象引起的输电线路的定期损坏也会影响供电。除此之外,电网的故障也会影响电力供应。因此,在这种情况下,我们可以利用本地发电站来满足当地的需求。局部电站与主电网配合使用,形成微电网,提高了可靠性,保证了供电的连续性。本文分析了基于200kWp微电网的太阳能光伏(SPV)系统以并网方式运行的情况。采用有功功率调节策略对系统的有功功率进行调节。为了进行分析,在MATLAB/Simulink中对系统进行了建模。该系统由两个与电网相连的SPV电站组成,每个SPV电站的容量为100kWp。采用基于摄动和观测的最大功率跟踪算法对电站进行最大功率跟踪。在控制方案中,将电网电压和逆变器电流转换为dq0坐标,并列举有功功率P和无功功率Q。计算的P和Q分别与Preference和Qreference进行比较。变换后的电压和电流也加了进去。在此之后,PWM发生器为逆变器开关产生触发脉冲。该控制策略在两个控制回路中运行,即外部功率控制回路和内部电流控制回路。锁相环还用于使逆变器输出的相位和频率与电网电压相匹配。得到的结果显示了SPV在每个辐照度和温度输入值下的峰值功率跟踪。结果还表明,采用该控制策略可以对电网的有功功率进行合理控制,并可以改变为任意参考值。

This work proposes weak bus constrained optimal placement of phasor measurement units (PMUs) in standard IEEE systems using binary Equilibrium Optimizer (BEO). The novelty of this work is to place the PMUs on such locations that weak buses are observed with maximum number of PMUs to ascertain full observability and stability of the system. The different combinations for installation of PMUs for other cases are also obtained by BEO. For investigating the effectiveness of the approach, it is tested on different test cases which are IEEE 14 bus, IEEE 30 bus, IEEE 57 bus and IEEE 118 bus systems with different conditions that include consideration of zero injection buses, single PMU outage, weak buses in the systems.
这项工作提出了弱总线约束下的相量测量单元(pmu)在标准IEEE系统中使用二进制平衡优化器(BEO)的最佳放置。这项工作的新颖之处在于将pmu放置在这样的位置,即弱总线被观察到的pmu数量最大,以确定系统的完全可观察性和稳定性。BEO还获得了其他情况下pmu的不同安装组合。为了验证该方法的有效性,在ieee14总线、ieee30总线、ieee57总线和ieee118总线系统的不同测试用例上进行了测试,测试用例考虑了系统中零注入总线、单PMU停电、弱总线等不同条件。

Random Forests are of the vital models in machine learning. They are comprehensive and effective classification paradigms in machine learning. The random forest recognizes the most important attributes of a given problem. The heart disorder is a cardiovascular disease, with a set of conditions affecting the heart. During heart disease there will be heart beat problems with congenital heart disorders and coronary artery defects. Coronary heart defect is a heart disease, which decreases the flow of blood to the heart. When the flow of blood decreases heart attack occurs. It is necessary to analyse the prediction of heart attack based on the symptoms. Available data set instances of the patients with heart defects symptoms is taken and analysed in this paper. Python language is utilized to prediction of the accuracy.

Since the word picture was coined, resolution has always been a challenge. Many studies have been conducted to generate high-resolution photographs, but none have been able to develop a process that is both time and quality effective. As a result, the super resolution issue is discussed in this paper using single-processing techniques. Deep learning methods are used to solve the same problem. The method suggested here will transform a low-resolution image into a high-resolution image of a pleasant and satisfactory quality. This can be accomplished using GANs (Generative Adversarial Networks) with significant up scaling factors.
自从“图片”这个词被创造出来,分辨率就一直是个挑战。已经进行了许多研究来生成高分辨率的照片,但没有一个能够开发出既有效又有效的过程。因此,本文采用单处理技术对超分辨率问题进行了讨论。深度学习方法被用来解决同样的问题。本文提出的方法将低分辨率图像转换为高分辨率图像,质量令人满意。这可以使用具有显著放大因子的GANs(生成对抗网络)来完成。

For electronic circuits, one of the most promising technology in modern days is Quantum Cellular Automata (QCA). It provides high speed, low power consumption and higher density as compared to CMOS technology. Quantumdot cell is a basic device which can be used to implement logic gates and various other digital circuits. In QCA, reversible computing approach helps in mitigating the power dissipation, hence providing a reliable solution. This paper presents a novel design for a reversible circuit which act as full adder, even parity as well as odd parity generator. Our proposed design is simple in structure with no garbage output. The design consists minimum number of clock zones and can be used for implementing various other logic gates. Simulation results are verified using software QCADesigner2.0.3.
