Optimization of unit commitment can be performed in various ways which include Dynamic Programming as one of the most reliable method. The precise meaning of unit commitment is scheduling of generators to increase the efficiency of generation while keeping the cost of generation to be minimum. This can be achieved by systematic following of the procedures of dynamic programming. Constraints related to dynamic programming enfolds the practical situations. Ideal situations can be often misinterpreted and certain factors of conditioning can be ignored. Hence, reliability constraint pertaining to risk of generation limit incapability is also important and down to be looked upon. Simulation of dynamic programming offers a better insight of the nominal and the actual values induced by using this programming method.
机组运行状态的优化有多种方法,其中动态规划是最可靠的方法之一。机组承诺的准确含义是对发电机组进行调度,以提高发电效率,同时保持发电成本最低。这可以通过系统地遵循动态规划程序来实现。与动态规划相关的约束包含了实际情况。理想的情况往往会被误解,某些条件作用的因素可能会被忽略。因此,与发电极限失效风险相关的可靠性约束也很重要,值得重视。动态规划的仿真可以更好地了解使用这种规划方法所得到的标称值和实际值。

This work illuminates the machine learning based fuzzy probability model for calculating the compost usability index and measuring its quality. The work reviews the basic concept of fuzzy theory and probability; status of Municipal waste and applications of fuzzy probability. Further work proposes Fuzzy-Probability Model to quantifying the compost quality by analyzing the compost data. Input variables are set of mineral nutrients and its composition in a sample. The output of (FPM) proposed system is the Quality Index of Compost $(C_{i})$ (i.e. measures of the proportion of all elements available in compost and generate an index accordingly, a numeric value) that describes the quality of compost asserting that even if the expertise describes suitability of values in a particular sample of compost, the quality decided by expert may be approximate, assumed or predicted. The results and conclusion show that the proposed FPM system gives a programming model that helps to generate a quality index for agriculture stakeholders to believe in a particular type of compost.

With the advent of social media the variety of digital media is growing exponentially. One of the purposes of media is to introduce a sense of joy among users. Multimedia customization and recommendations depend on emotional traits of the content a user is watching. The levels of media enjoyment of a normal person are usually extracted using various surveys or feedback gathering. Enjoyment level varies from an individual to another, the presence of techniques for gathering this kind of feedback from paralyzed will make a breakthrough in media content feedback of such people. In this paper, EEG data is acquired from Neurosky Mindwave headset. The data is then transformed to frequency domain using Fourier transform and various feature extraction steps are performed. Enjoyment level is divided into four levels based on the attention of the user. Finally, an attempt is made to draw a conclusion from the achieved result that this enjoyment level detection mechanism can be integrated with a web application which can help paralyzed people customize their choices of media they are interested in watching.
随着社交媒体的出现,数字媒体的种类呈指数级增长。媒体的目的之一是在用户中引入一种快乐的感觉。多媒体定制和推荐取决于用户正在观看的内容的情感特征。一个正常人的媒体享受程度通常是通过各种调查或反馈收集来提取的。每个人的享受程度都是不同的,收集这种瘫痪者反馈的技术的出现将会为这类人的媒体内容反馈带来突破。本文的脑电图数据采集自Neurosky Mindwave耳机。然后使用傅里叶变换将数据转换到频域,并进行各种特征提取步骤。根据用户的注意力,将享受程度分为四个层次。最后,我们试图从已经取得的结果中得出结论,这种享受水平检测机制可以与一个web应用程序集成,帮助瘫痪患者定制他们感兴趣的媒体选择。

The aim of this work is to determine the effective passive measures to enhance the thermal comfort of the building envelop. Passive measures are those measures which reduce electricity demand but do not require any electricity to operate. The building components such as walls, roof and window are exposed to solar radiation and outside air temperature. Heat is conducted from exterior environment into the interior of the building envelop through these channels, wherein majority (approx. 60%) is conducted by walls and roof. Envelop insulation is considered as an efficient retrofitting measure to reduce heat gain from walls and roof. In this study, a techno-economic model has been investigated to obtain optimum insulation thickness (OIT) for the residential buildings in the three climate zones of India. Four types of commonly used insulation materials analysed are: expanded polystyrene (EPS), extruded polystyrene (XPS), fiberglass and polyurethane foam (PUF). The effect of cooling design temperature and the coefficient of performance (COP) of air conditioners on the insulation thickness were also investigated. Fiberglass is observed as the most cost effective insulation material, considering life cycle performance of the insulation material for all the climate zones. It was also concluded that air-conditioner with higher COP can potentially reduce the insulation cost.
本工作的目的是确定有效的被动措施,以提高建筑围护结构的热舒适性。被动措施是那些减少电力需求但不需要任何电力来运行的措施。建筑构件如墙壁、屋顶和窗户暴露在太阳辐射和外部空气温度下。热量通过这些通道从外部环境传导到建筑围护结构的内部,其中大部分(约为。60%)由墙壁和屋顶传导。围护结构保温被认为是一种有效的改造措施,以减少从墙壁和屋顶的热量增益。在这项研究中,研究了一个技术经济模型,以获得印度三个气候带住宅建筑的最佳保温厚度(OIT)。分析了四种常用的绝缘材料:膨胀聚苯乙烯(EPS)、挤压聚苯乙烯(XPS)、玻璃纤维和聚氨酯泡沫(PUF)。研究了空调的冷却设计温度和性能系数对保温厚度的影响。考虑到保温材料在所有气候带的生命周期性能,玻璃纤维被认为是最具成本效益的保温材料。同时也得出了更高COP的空调有可能降低保温成本的结论。

This paper investigates the applications of Machine Learning in recognition of 2D drawings of machine components. Recognition of primitive geometric shapes such as polygons within engineering drawings forms basic element of such approach. Machine learning algorithms are used to identify 3 to 7 sided polygons with random shapes and segmented edges. The uncertainty induced by segmented edges poses a challenge for predicting number of sides using statistical method such as Machine Learning. Different types of datasets with varying amount of uncertainty are used. The recognition of shapes is attempted with different sets of features such as coordinates of points, slopes of lines and geometric parameters such as area, perimeter and centroid. Three machine learning models namely, Random Forest Classifier, K- Nearest Neighbors Classifier and Support Vector Classifier are adopted. The performance of these models for identification of polygons is discussed.

Time to Digital Converters has been used to measure time difference between two events with high accuracy and resolution approx. 100 ps. In this paper, it is proposed to develop a data acquisition system for Time-of-Flight measurement using Time to Digital converter. The firmware for the system is designed around PIC 18F4550 microcontroller and TDC7200 integrated circuit. The system has been programmed to configure Time to Digital Converter using SPI line and log out the acquired data over to PC via UART. The readout system has been tested with calibrated delay inputs to examine the different working modes of operation. The gathered data has been analyzed using ROOT framework. The cost effective alternative for the Time to Digital Converter evaluation module also has been discussed and designed to be compatible with microcontrollers as well as Field Programmable Gate Array devices.

Developing a system which can be used for detection of faulty Integrated circuits (ICs) is one of the major challenge in electronic industry. Heating in ICs due to various reasons which may lead to degradation of performance and can cause serious hazardous effects in Printed Circuit Boards (PCB). Thermal image processing is one of the best non-contact, non-invasive method which can be used for IC fault detection. The paper aims towards detection of faulty ICs in PCB with help of thermal imaging camera and image processing techniques. Thermal images of sequence detector circuit for different fault conditions are collected. Image matching is achieved by comparing features of training images and test image using Speeded-Up Robust Features (SURF) algorithm. The system will indicate image belongs to particular fault class. The proposed method detects and classify possible faulty IC conditions with improved accuracy and can also help in early prevention remotely before complete circuit failure.
开发一种可用于故障集成电路检测的系统是电子工业面临的主要挑战之一。由于各种原因,集成电路中的发热可能导致性能下降,并可能对印刷电路板(PCB)造成严重的危险影响。热图像处理是集成电路故障检测中一种最好的非接触式、非侵入式检测方法。本文的目的是利用热像仪和图像处理技术来检测PCB中的故障集成电路。采集了不同故障条件下序列检测器电路的热图像。采用加速鲁棒特征(SURF)算法对训练图像和测试图像进行特征比较,实现图像匹配。系统将显示图像属于特定的故障类别。所提出的方法以更高的精度检测和分类可能的故障IC条件,并有助于在完全电路故障之前进行远程早期预防。
