This research work develops an explicit nonlinear model predictive control strategy for an aerodynamical model i.e. twin rotor MIMO system (TRMS). Here the control strategy is developed by calculating the tracking error as well as the control signal in the prediction horizon using Taylor series expansion. The explicit solution for the control signal is obtained from an optimal performance index which can be developed without online optimization. The complete state information of the system to the proposed controller is given from an ensemble Kalman filter (EnKF) based state observer. The simulation and real-time results are documented in graphical form to confirm the efficiency of the proposed controller.

The paper proposes "Anti-spoofing application for desktop". This application uses a face recognition approach along with the use of eye-blink count to detect liveness. Main phases of application are namely, face detection and recognition, and determination of liveness status of user. Liveness detection is proven to prevent the video play-back attacks and use of printed photograph in order to compromise the security. Webcam captures the user’s image after every short interval of time. Image captured after passing authentication process is checked for liveness. In case of security breach, countermeasures are executed. This include capturing image of adversary and system logoff or exit. This paper proposes an additional functionality which uses HOG feature descriptor of user image along with passcode. It uses SVM classifier that gives performance metric of 100% accuracy. The experimental results of the ameliorated functionality show the effectiveness of the proposed approach.

Aim of forecasting electrical load focuses in predicting satisfactorily and accurately the demand that might increase or decrease in the future. A large number of engineering applications count on accurate and reliable prediction models for electrical load demand. A precise forecasting of load helps in planning the capacity and operations of power companies to reliably supply energy to the consumers. In this study electrical load (L) in Assam is predicted using a data driven forecasting scheme. The study is carried out using daily 24 hourly L data obtained from SLDC, Kahilipara, Assam. The study focuses mainly on two types of regression model: ARIMA and SARIMA and also provides a performance evaluation of the models. The input data has been split into two groups of training and testing data to build the forecasting model. The correctness of the forecasting models has been assessed using the different error matrices. The final results indicated that the SARIMA model that considers the seasonality of load data provided better prediction with minimum error. MATLABR2016a was used during the entire analysis.

This paper discusses different components of hybrid renewable energy system on basis of technical parameters, sizing issues, power converter architecture and challenges faced by each of them. Since optimal operating point of whole hybrid system is required, it is necessary that not only each component operate at its own optimal operating point, but it should also complement operating point of other components. Main challenge with PV system is associated with partial shading and local maximum power point, which affects maximum power extraction from system. In case of Wind system, sizing of turbines, power fluctuation which can affect grid frequency is major issue. Battery energy storage system suffers from battery aging issues. Technical limitations of individual components can somewhat be addressed by complimentary advantage of other component and power flow fluctuation can addressed by suitable design of energy storage system. Cost of energy storage system be reduced too if extra power can be injected to the grid as in the case of grid connected system. Some hybrid system provides possibility of better resource utilization potential, while other can provide better dynamic and/or steady state performance depending on requirements. Hybrid system can also address shortcoming of one energy resource by providing complimentary parameter which can make up for such shortcoming. Factors which determine what hybrid system to choose for depends purely on requirements.
本文讨论了混合可再生能源系统的不同组成部分的技术参数、规模问题、电源转换器的结构以及各自面临的挑战。由于要求整个混合动力系统的最优工作点,所以不仅要求各部件在自己的最优工作点运行,而且要求各部件对其他部件的工作点进行补充。光伏系统的主要挑战是局部遮阳和局部最大功率点,影响系统的最大功率提取。在风力发电系统中,风力发电机组的尺寸、功率波动对电网频率的影响是主要问题。电池储能系统存在电池老化问题。单个组件的技术限制可以通过其他组件的互补优势来解决,潮流波动可以通过适当的储能系统设计来解决。与并网系统一样,如果能向电网注入额外的电力,也能降低储能系统的成本。一些混合系统提供了更好的资源利用潜力的可能性,而另一些混合系统可以根据需求提供更好的动态和/或稳态性能。混合动力系统还可以通过提供补充参数来弥补某一能源的不足。决定选择哪种混合系统的因素完全取决于需求。

Land cover classification using satellite images is an important tool in the study of terrestrial resources. Satellite based information is presently available as huge sets of high resolution images from a large number of satellites like Sentinel, Landsat-8, etc. Land cover classification from these images is a difficult task because of very large sized data and high variation types. Deep Neural Networks can play a vital role in this regard and can perform classification on these large sized data. Related works in this field have used lighter models and included a large number of handcrafted parameters which requires domain knowledge on the subject. It is realised that most models are too shallow for such a complicated image. In this paper, a deeper Convolutional Neural Network (CNN) model without any satellite image specific parameters is proposed. On SAT4 and SAT6 images, our 13-layered network has achieved better accuracy upto 99.84% and 99.47% which is state-of-the-art. It is still called lightweight model because most models in Artificial Intelligence(AI)-CNN are much deeper and larger than ours.
利用卫星影像进行土地覆被分类是陆地资源研究的重要工具。目前,基于卫星的信息是来自大量卫星(如Sentinel, Landsat-8等)的大量高分辨率图像。从这些图像中进行土地覆盖分类是一项艰巨的任务,因为数据量非常大,变化类型也很高。深度神经网络可以在这方面发挥至关重要的作用,并且可以对这些大型数据进行分类。该领域的相关工作使用了较轻的模型,并包含大量手工制作的参数,这需要该主题的领域知识。人们意识到,对于如此复杂的图像,大多数模型都太浅了。本文提出了一种不含卫星图像特定参数的深度卷积神经网络(CNN)模型。在SAT4和SAT6图像上,我们的13层网络的准确率达到了99.84%和99.47%,达到了最先进的水平。它仍然被称为轻量级模型,因为人工智能(AI)-CNN中的大多数模型都比我们的模型更深更大。

The number of data centers is increasing rapidly since more people are now using cloud services for data storage and management. Due to this, the total power consumption of the data centers is also increasing. The energy efficiency of the data centers is not very high due to a variety of reasons like heat loss by equipment and power factor issues. This paper attempts to review the existing work around 2015 to 2019 and understand the issues faced by the data centers. The energy usage by the data centers and the effect of the temperatures are reviewed along with the methods of optimisation through Machine Learning (ML) algorithms. Some of the factors affecting the energy consumption of the data centers are the airflow, heat loss, ambient temperature, among others. The gap in the existing research is obtained by identifying the various factors that affect the cooling of the data centers. The effect of the cooling parameters is optimised at different locations of the data centers as per the requirement. Reinforced learning techniques have been seen to be efficient in terms of optimisation. A combination of Support Vector Machine (SVM) and Ant Colony Optimisation (ACO) is suggested as a future scope of this study.
由于越来越多的人使用云服务进行数据存储和管理,数据中心的数量正在迅速增加。因此,数据中心的总功耗也在不断增加。由于各种原因,如设备的热损失和功率因素问题,数据中心的能源效率不是很高。本文试图回顾2015年至2019年前后的现有工作,并了解数据中心面临的问题。数据中心的能源使用和温度的影响以及通过机器学习(ML)算法进行优化的方法进行了审查。影响数据中心能耗的一些因素包括气流、热损失、环境温度等。通过识别影响数据中心冷却的各种因素,得出了现有研究的空白。根据需求,在数据中心的不同位置优化冷却参数的效果。强化学习技术在优化方面被认为是有效的。建议将支持向量机(SVM)和蚁群优化(ACO)相结合作为本研究的未来范围。

This paper describes the design and fabrication of a voltage tunable Microstrip line hairpin structured band-pass filter at 27.6 GHz centre frequency. To get frequency tunability, Barium Strontium Titanate (BST) based parallel plate varactor is used. Parallel plate varactor is designed in which BST is used as dielectric and the designed varactor is integrated in the microstrip line band pass filter. The schematic and layout design of the filter is designed and simulated in Advanced Design System (ADS) simulation software. For filter layout design sapphire (Ɛr =11.58) is considered as substrate and the metal electrodes used are platinum and gold. The S parameters observed are insertion loss (S21) of around -1dB and Return loss (S11) of less than −20dB. All the simulations are done in Advanced Design System (ADS).
本文介绍了一种中心频率为27.6 GHz的微带线发夹结构带通滤波器的设计与制作。为了获得频率可调性,采用了基于钛酸锶钡(BST)的平行板变容管。设计了以BST为介质,集成在微带线带通滤波器中的平行板变容管。在先进设计系统(ADS)仿真软件中对滤波器的原理图和布局设计进行了设计和仿真。对于滤波器布局设计,蓝宝石(Ɛr =11.58)被认为是衬底,使用的金属电极是铂和金。观测到的S参数为插入损耗(S21)约为-1dB,回波损耗(S11)小于- 20dB。所有仿真均在先进设计系统(ADS)中完成。

Food processing industries plays a vital role for the development of our country. Mango is one of the economical fruit because of its nutrient dense foods. In general, ripening stage classification done by human experts which is strenuous process and a challenging task for food processing industry. A machine learning approach for ripening stage classification has been proposed. A MATLAB based implementation shows that Ensemble classifier outperform their counter parts discriminant classifier in terms confusion matrix, average accuracy, precision, recall, specificity and F-score.So,Maturity index classification of mango plays very important role to get to know about shelf life of mangoes. Thus this paper proposes effective mango fruit grading using machine learning approaches.
食品加工业对我国的发展起着至关重要的作用。芒果是一种营养丰富的经济水果。一般来说,成熟阶段的分类是由人类专家完成的,这是一个艰苦的过程,也是食品加工业的一项具有挑战性的任务。提出了一种成熟阶段分类的机器学习方法。基于MATLAB的实现表明,集成分类器在混淆矩阵、平均准确率、精密度、召回率、特异性和f分等方面优于同类判别分类器。因此,芒果成熟度指数分级对了解芒果的货架期具有十分重要的意义。因此,本文提出了使用机器学习方法对芒果果实进行有效分级的方法。
