Behavioral finance proposes that cognitive traits of investors impact their investment decisions which are not always rational, in contradiction to traditional finance. These cognitive traits of stock investors are influenced by their demographical profile and the financial information that they receive from various sources which in turn influences their stock investment decisions. Investors with similar demographic profile tend to follow a similar pattern with regard to their investment behavior biases. The main objective of this study is to analyze the impact of Indian stock investors' demographics and various sources of financial information on their cognitive biases. Various behavioral biases like herding, loss aversion, regret aversion, market information; mental accounting, price change, and price anchoring were studied but herding behavior has been taken into consideration for analysis in this study. A questionnaire was floated by using quota sampling. Stata software was used for analysis, by using ordered logistic regression on the conceived model. Gender, age, marital status and word of mouth are found to have significant impact on the herding behavior of stock investors.
行为金融学与传统金融学相矛盾,认为投资者的认知特征会影响投资者的投资决策,而投资者的投资决策并不总是理性的。股票投资者的这些认知特征受到他们的人口特征和他们从各种来源获得的财务信息的影响,这些信息反过来又影响他们的股票投资决策。具有相似人口特征的投资者在投资行为偏差方面往往遵循相似的模式。本研究的主要目的是分析印度股票投资者的人口统计数据和各种财务信息来源对其认知偏差的影响。各种行为偏差,如羊群效应,损失厌恶,后悔厌恶,市场信息;本研究研究了心理会计、价格变化和价格锚定,但在分析中考虑了羊群行为。采用定额抽样的方法进行问卷调查。采用Stata软件进行分析,对所构想的模型进行有序逻辑回归。性别、年龄、婚姻状况和口碑对股票投资者的羊群行为有显著影响。

An interfacing device plays important role in data acquisition systems. However, different signal types of sensors in general are limited by these devices. Gradual improvement of IoT has lead to a revolution in the wireless communication; this scenario facilitates various applications from environmental monitoring to industrial management. Wired networks are mostly used to transfer data by connecting sensor. It is advantageous as it provides reliable communication system for instruments and controls. But connecting the sensors with a wired network will be costly hence low cost wireless technologies are much needed to cut down the cost. A novel approach is proposed in this paper to design smart sensor interface for water quality monitoring in IoT environment. Different sensors are available for water quality monitoring which are used to check the quality on following parameters i.e. pH, dissolved oxygen concentration, turbidity and temperature etc. IoT provide interface to monitor and operate remotely from anywhere and anytime. Intel Galileo Gen 2 board is used as interfacing device in our proposed system. The system performance is tested on water environment monitoring and improved results are gained.
接口设备在数据采集系统中起着重要的作用。然而,不同信号类型的传感器通常受到这些设备的限制。物联网的逐步完善引发了一场无线通信的革命;这种场景有利于从环境监测到工业管理的各种应用。有线网络主要通过连接传感器来传输数据。它的优点是为仪器和控制提供了可靠的通信系统。但将传感器与有线网络连接将是昂贵的,因此需要低成本的无线技术来降低成本。本文提出了一种设计物联网环境下水质监测智能传感器接口的新方法。不同的传感器可用于水质监测,用于检查以下参数的质量,即pH值,溶解氧浓度,浊度和温度等。物联网提供接口,可以随时随地远程监控和操作。本系统采用Intel Galileo Gen 2板作为接口器件。在水环境监测中对系统进行了性能测试,取得了较好的效果。

The Cathode Ray Tube (CRT) experiment performed by J. J. Thomson, is one of the most well-known physical experiments, which led to the discovery of electrons. The experiment could also describe characteristic properties, essentially, its affinity towards positive charge, and its charge to mass ratio. This paper describes the simulation of J. J. Thomson's Cathode Ray Tube experiment. The major contribution of this work is the new approach for modelling this experiment, with a great deal of accuracy and precision, using the equations of physical laws to describe the motion of the electrons. The motion of the electrons can be manipulated and recorded by the user, by assigning different values to the experimental parameters. This can be used as a good learning tool by the needy.

Anthracnose and leaf spot (red rust) are the common diseases affecting the mango plant. Mango being economically important, the detection of these diseases is critical for avoiding epidemics and loss of yield. A machine vision approach has been proposed for plant disease identification using colour images of mango leaves. This approach included using YCbCr converted image and creating a feature vector of textural and colour features of the input images which are fed to the classifier during the testing phase. GLCM, colour based technique and Gabor filter were used for texture and colour feature extraction. Comparison of results obtained using a Minimum distance classifier and using Support Vector Machine (SVM) has been done. Analysis of the feature extraction techniques was performed to obtain individual results for each technique. The overall results gave a classification accuracy of 79.16% and 83.34% for Minimum distance classifier and Support Vector Machine respectively over a database of 86 images.

The polyphase systems plays vital role in electrical systems due to its various advantages in power transmission and drives. In balanced polyphase system, due to the disturbances unbalances may occur which may depend on construction of winding and type of load. Therefore it is very essential to analyze the system components like voltages and currents. To carry out this analysis in phase components is tedious. Sequence components analysis is widely used in power sector to analyze the unbalanced systems and faults. This paper presents mathematical analysis of three phase, five phase and six phase symmetrical components and to simplify the understanding of sequence components comparative performance is analyzed using MATLAB script.

The main motto of power system is to provide reliable power supply with most economical cost. To achieve this motto, there is need of various tools which can monitor, analyze and control the power system. Few of them are Economic Dispatch (ED) and optimal power flow (OPF). ED has aims to plan committed generating units to fulfill load demand for minimizing cost without violating equality and inequality constraints. OPF problem is tool to achieve optimal state of control variables by minimizing desired objective with satisfying all related constraints. The conventional methods are used to solve OPF but due to hybrid generation scenario the system become more complex where conventional method fails to achieve objective. So nature inspired called artificial intelligence methods inspected to solve complex OPF problem. The focus of this paper to prompt review study on various optimization techniques used to solve OPF for better understanding of all methods used in past.
电力系统的主要宗旨是以最经济的成本提供可靠的电力供应。为了实现这一目标,需要各种能够监测、分析和控制电力系统的工具。其中经济调度(ED)和最优潮流(OPF)问题较少。电力系统的目标是在不违反相等和不相等约束的情况下,规划承诺发电机组以满足负荷需求,从而使成本最小化。OPF问题是在满足所有相关约束条件的情况下,通过最小化期望目标来实现控制变量最优状态的工具。传统的方法求解OPF,但由于混合发电场景的存在,系统变得更加复杂,传统的方法无法达到目标。因此大自然启发了人工智能方法来解决复杂的OPF问题。为了更好地理解过去使用的所有方法,本文的重点是提示对用于解决OPF的各种优化技术的回顾研究。

Tree structured vector quantization based technique for speech compression 基于树结构矢量量化的语音压缩技术
Pub Date : 2017-02-01 DOI: 10.1109/ICDMAI.2017.8073524

In this paper, the Tree-Structured Vector Quantization (TSVQ) method for proficient speech compression is presented. Efficient utilization of memory is always needed when analog-encoded or digitized data such as image, audio, videos, portable files are need to store and/or convey to digital channels. Compression offers betterments with storage requirements while transmitting the encoded signals with lossy and lossless techniques. Lossy compression is always intended for compression of high volume data with Scalar Quantization (SQ) and Vector Quantization (VQ). The Tree based VQ method is used with hieratically organized binary sequences of codeword of data (speech) for compression with reduced and minimized arithmetic calculation requirements. Speech compression has been gained by compressed-codebook coefficients and structured in binary fashion. The quantization noise ratio with signal power is obtained efficiently around less than 1.082 dB. Shared codebook method described in this TSVQ algorithm achieves 3.6 reduced storage requirements of factor 5 to 3.
提出了一种高效语音压缩的树结构矢量量化(TSVQ)方法。当模拟编码或数字化数据(如图像、音频、视频、便携式文件)需要存储和/或传输到数字通道时,总是需要有效地利用内存。压缩提供了更好的存储要求,同时以有损和无损技术传输编码信号。有损压缩通常用于使用标量量化(SQ)和矢量量化(VQ)压缩大容量数据。基于树的VQ方法用于分层组织的数据(语音)码字二进制序列进行压缩,减少和最小化了算法计算需求。语音压缩是通过压缩码本系数并以二进制方式结构化来实现的。在小于1.082 dB左右有效地获得了量化噪声与信号功率的比值。该TSVQ算法所描述的共享码本方法实现了3.6倍的存储需求降低,存储需求降低了5到3倍。

Efficient utilization of memory is always needed when analog-encoded or digitized data such as image, audio, videos, portable files are need to store and/or convey to digital channels. Compression offers betterments with storage requirements while transmitting the encoded signals with lossy and lossless techniques. Lossy compression is always intended for compression of high volume data with Scalar Quantization (SQ) and Vector Quantization (VQ). The Tree based VQ method is used with hieratically organized binary sequences of codeword of data (speech) for compression with reduced and minimized arithmetic calculation requirements. Speech compression has been gained by compressed-codebook coefficients and structured in binary fashion. The quantization noise ratio with signal power is obtained efficiently around less than 1.082 dB. Shared codebook method described in this TSVQ algorithm achieves 3.6 reduced storage requirements of factor 5 to 3.","PeriodicalId":368507,"journal":{"name":"2017 International Conference on Data Management, Analytics and Innovation (ICDMAI)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123300472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines the determinants of India's implied volatility index (VIX). The factors considered are Purchasing Managers Index (PMI), Business Confidence Index (BCI), Net activity of Foreign Institutional Investors (FII) and Net activity of Domestic Institutional Investors (DII). In this study Granger causality is used to find whether these factors cause IndiaVIX. This study confirms that only BCI has significant and positive impact with IndiaVIX and other factors such as PMI, FII and DII do not have any significant impact on India VIX. The results show that FII has a significant and negative impact on DII and hence these two factors do not have a significant impact on IndiaVIX.
本研究考察了印度隐含波动率指数(VIX)的决定因素,考虑的因素包括采购经理人指数(PMI)、商业信心指数(BCI)、外国机构投资者净活跃度(FII)和国内机构投资者净活跃度(DII)。本研究使用格兰杰因果关系来确定这些因素是否导致了IndiaVIX。本研究证实,只有BCI对印度VIX有显著的正向影响,PMI、FII、DII等其他因素对印度VIX没有显著影响。结果表明,FII对DII有显著的负向影响,因此这两个因素对IndiaVIX没有显著影响。
