Navneet Kaur, N. Gupta, Hitesh Pahuja, Balwinder Singh, S. Panday
Memory occupies more than 70 percent of area in today's system on chip and the trends continue to be increases in coming years. As the technology is scaling the bulk MOSFET faces various challenges which lead to increased leakage. Below 32nm technology, FinFET is the most promising substitute to bulk CMOS technology because of reduced short channel effect. The proposed 10T SRAM cell is designed using MOSFET, FinFET at 16nm technology node and its performance parameters such as power, delay, Power Delay Product (PDP), leakage current and Static Noise Margin (SNM) are compared with conventional 6T SRAM cell.

Implementation of high frequency fractional order differentiator 高频分数阶微分器的实现
Nitisha Shrivastava, P. Varshney
In this paper a new approach is suggested for implementing fractional order differentiator in the desired frequency band based on frequency capacitance scaling. The process involves obtaining the rational approximate model of the fractional order differentiator using Matsuda method of approximation and then decomposing it by partial fraction expansion to obtain the circuit parameters (resistance and capacitance). If the frequency band of interest has now to be changed, only the capacitances of the resulting circuit are scaled proportionately. For the choice of the method of approximation and the approach for synthesis, emphasis has been given to accuracy of the model obtained and positive values of resistances and capacitances. The simulations have been performed using OrCAD Capture CIS simulator.
本文提出了一种基于频率电容缩放的分数阶微分器在期望频带内的实现方法。该过程是利用Matsuda近似法得到分数阶微分器的有理近似模型,然后通过部分分式展开进行分解,得到电路参数(电阻和电容)。如果现在要改变感兴趣的频带,则只需要按比例缩放所得到的电路的电容。对于逼近方法和综合方法的选择,重点是模型的准确性和电阻值和电容值的正值。采用OrCAD Capture CIS仿真器进行仿真。

Analysis of short circuit electromagnetic forces in transformer with asymmetrically placed windings using Finite Element Method 非对称绕组变压器短路电磁力的有限元分析
A. Sinha, Sarpreet Kaur
Short circuit electromagnetic (EM) forces are considered as important factor and should be taken care of while designing a transformer. The effect of forces is more important in case of large transformers, but the procedure of analysis of forces is same for both power transformers and power distribution transformers. Therefore, a 630kVA, 11/.433kV power distribution transformer has been modeled for analyzing the forces using Finite Element Method (FEM). Windings are modeled into twenty three sections and short circuit EM force of each and every section of the winding is calculated. The forces are calculated under worst fault condition of three phase symmetrical short circuit current. In practical transformer, there is some axial asymmetry between the windings. Net axial force experienced by the windings because of absence of symmetry is calculated and effect of tapping on short circuit EM forces is also included in this study.
短路电磁力是设计变压器时应考虑的重要因素。对于大型变压器,力的作用更为重要,但对电力变压器和配电变压器的力的分析过程是相同的。因此,一个630kVA, 11/。采用有限元法对433kV配电变压器进行了受力分析。将绕组建模为23段,计算了每段绕组的短路电磁力。计算了三相对称短路电流最坏故障条件下的受力情况。在实际的变压器中,绕组之间存在一定的轴向不对称。计算了绕组因不对称而受到的净轴向力,并考虑了攻丝对短路电磁力的影响。

Continuous sliding mode controller design for inverted pendulum system 倒立摆系统的连续滑模控制器设计
Saurabh Saini, B. Pratap, Surinder Singh
This paper presents a non linear robust controller for inverted pendulum system (IPS) using continuous sliding mode control (CSMC) technique. The CSMC is obtained by replacing the discontinuous element of integral sliding mode control (ISMC) approach. The super twisting control algorithm is used as a disturbance estimator which rejects the effect of disturbances. The undesirable chattering effect due to discontinuous term present in conventional ISMC has been completely removed using proposed continuous approach. Finally, the superiority of proposed control scheme has been demonstrated throw simulation results to depict its effectiveness.

N. Goel, Akhilendra Yadav, B. Singh
The advent of computer aided technologies image processing techniques have become increasingly important in a wide variety of medical applications. Intervention between the protection of useful diagnostic information and noise suppression must be treasured in medical images. Image denoising is an applicable issue found in diverse image processing and computer vision problems. There are various existing methods to denoise images. The important property of a good image denoising model is that it should completely remove noise as far as possible as well as preserve edges. This paper presents a review of some major work in area of image denoising. The objective in all discipline is to extract information about the scene being imaged. The rapid progress in computerized medical image reconstruction and the associated developments in analysis methods and computer-aided diagnosis has boosted medical imaging into one of the most important sub-fields in scientific imaging Ultrasound, MRI, CT-Scan, PET Scan are the medical techniques mainly used by the radiologist for visualization of internal structure of the human body without any surgery. These provide ample information about the human soft tissue, which helps in the diagnosis of human diseases.
随着计算机辅助技术的出现,图像处理技术在各种各样的医学应用中变得越来越重要。在医学图像中,保护有用的诊断信息和抑制噪声之间的干预必须得到重视。图像去噪是一个适用于各种图像处理和计算机视觉问题的问题。现有的图像去噪方法多种多样。一个好的图像去噪模型的重要特性是在保留边缘的同时尽可能的完全去噪。本文综述了图像去噪领域的一些主要研究成果。所有学科的目标都是提取被成像场景的信息。计算机医学图像重建技术的快速发展以及与之相关的分析方法和计算机辅助诊断的发展,使医学成像成为科学成像中最重要的子领域之一。超声、MRI、ct扫描、PET扫描是放射科医生主要使用的医学技术,可在不进行任何手术的情况下实现人体内部结构的可视化。这些提供了关于人体软组织的丰富信息,有助于人类疾病的诊断。
