A New Fuzzy Clustering Algorithm for Brain MR Image Segmentation Using Gaussian Probabilistic and Entropy-Based Likelihood Measures 基于高斯概率和熵似然测度的脑磁共振图像模糊聚类分割新算法
Sayan Kahali, J. Sing, P. Saha
Medical image segmentation plays a crucial role in medical image analyses, computer-guided surgical planning, abnormality detection, etc. The magnetic resonance (MR) image segmentation process is much more challenging as the contour of the soft tissue regions are vague or uncertain. This paper presents a new fuzzy clustering algorithm to address the class uncertainty associated with each pixel in the image region. In particular, the class uncertainty is handled by integrating the Shannon’s entropy within the objective function. In addition, the objective function also includes Gaussian probabilistic measure to estimate the membership function. The proposed algorithm is validated on several synthetic brain MR images with varying noise and inhomogeneity. Additionally, we have also validated the method on in-vivo (real-patient) human brain MR images. The empirical results of the proposed algorithm are compared with some competent image segmentation methods and found superior to them.
医学图像分割在医学图像分析、计算机指导手术计划、异常检测等方面起着至关重要的作用。由于软组织区域的轮廓模糊或不确定,磁共振图像分割过程更具挑战性。本文提出了一种新的模糊聚类算法来解决图像区域中每个像素相关的类不确定性。特别地,类的不确定性是通过在目标函数内积分香农熵来处理的。此外,目标函数还包含高斯概率测度来估计隶属函数。在不同噪声和非均匀性的合成脑MR图像上验证了该算法。此外,我们还在活体(真实患者)人脑MR图像上验证了该方法。将该算法的实验结果与现有的图像分割方法进行了比较,发现其优越性。

Modified Binary Dragonfly Algorithm for Feature Selection in Human Papillomavirus-Mediated Disease Treatment 基于改进二进制蜻蜓算法的人乳头瘤病毒介导疾病治疗特征选择
Ramit Sawhney, Roopal Jain
Diseased caused through the rapid mediation of Human Papillomavirus (HPV) have surged in the recent decades. While there are a large amount of treatment methods, medical data is often voluminous, high dimensional and often has redundancy which make selection of a particular method difficult. Wrapper feature selection methods aim to extract a subset of features to improve computability as well as classification accuracy. To address this, we propose a modification to a relatively new evolutionary computation technique, the Binary Dragonfly algorithm (BDFA), by incorporating a penalty function for optimal feature selection. This wrapper based method using BDFA and Random forest classifier is employed on two treatment methods, Immunotherapy and Cryotherapy, showing an increase in both classification accuracy as well as feature reduction as compared to fuzzy rule based systems, genetic algorithms and random forest classifiers
近几十年来,通过人乳头瘤病毒(HPV)的快速介导引起的疾病激增。虽然有大量的治疗方法,但医疗数据往往是大量的,高维的,往往有冗余,这使得选择一种特定的方法很困难。包装器特征选择方法旨在提取特征子集,以提高可计算性和分类精度。为了解决这个问题,我们提出了一种相对较新的进化计算技术——二进制蜻蜓算法(BDFA)的改进,通过加入一个最优特征选择的惩罚函数。将基于包装的BDFA和随机森林分类器的方法应用于免疫治疗和冷冻治疗两种治疗方法,与基于模糊规则的系统、遗传算法和随机森林分类器相比,分类精度和特征约简都有所提高

Far Infrared based Life Detection System to Rescue Alive Victims under Debris 基于远红外的残骸救援系统
Jaisa Mariam Jacob, M. Methini
A brief review of the conventional life detection systems is carried out and the design of a novel system using Far Infrared (FIR) region of the infrared spectrum is proposed. FIR rays with the wavelength range 1mm to 1μm are currently being explored by scientists for its biological effects. This paper puts forth the idea of using these rays in rescue operation systems subsequent to disasters like earthquakes to save the people trapped under the wreckage. Detection of life can be accomplished based on the changes in the properties exhibited by FIR rays when they are absorbed and radiated back by the living matter and reflected by the nonliving materials. By detecting the presence of life in the victims, a lot of time for rescue can be saved and mortality rate can be significantly reduced.
对传统的生命探测系统进行了简要的回顾,并提出了一种利用红外光谱中的远红外(FIR)区域的新型生命探测系统的设计。目前,科学家们正在研究波长为1毫米至1μm的FIR射线的生物效应。本文提出了在地震等灾害后的救援操作系统中利用这些射线来拯救被困在废墟下的人的想法。对生命的探测可以根据FIR射线被生物物质吸收和辐射回来并被非生物物质反射时所表现出的性质的变化来完成。通过检测受害者的生命存在,可以节省大量的救援时间,并可以大大降低死亡率。

An Automated Approach to Weed Out Prosopis Juliflora(Karuvelam) Trees 一种自动除草法在黄花拟豆树(Karuvelam)中的应用
M. Devadharshini, M. Rajeswari, S. Sumathi
Computing technology is not only crucial but also related to environmentalists and other related authorities. Agriculture is the backbone of India, which is greatly affected due to the insufficient water supply. Prosopis juliflora (karuvelam trees) which is used only as a firewood has greater environmental impacts such as water absorption from the soil and moisture from atmosphere, emits low oxygen and more carbon dioxide comparatively. This project has been designed to give a complete solution for the eradication of karuvelam trees, as the manual removal and using heavy machines may increase the number of labours and cost for removing these trees with long penetrating roots. Much more number of trees can be eradicated using technical methods.In this project, we propose a cloud based approach for identification of karuvelam trees affecting agricultural lands using Deep learning. The system consists of a setup which can identify karuvelam leaves from images and retrieve the GPS location and update the cloud. The Data is processed in the cloud and the instruction is delivered to the chemical spraying setup through IOT board to kill the weeds. Our project aims at designing a prototype to prove that the code that we have developed for identification of karuvelam trees works well in real system. The concept can be incorporated in real world using OPTiM agri drone(automatic weedicide sprayer on selected weeds) designed by Japan.
计算技术不仅至关重要,而且与环保主义者和其他相关当局有关。农业是印度的支柱,但由于供水不足,农业受到了很大的影响。仅作为柴火使用的黄豆(karuvelam trees)对环境的影响更大,如从土壤中吸收水分和从大气中吸收水分,排放的氧气较少,二氧化碳较多。这个项目的目的是为铲除karuvelam树木提供一个完整的解决办法,因为人工铲除和使用重型机器可能会增加铲除这些具有长穿透根的树木的劳力数量和费用。使用技术方法可以铲除更多的树木。在这个项目中,我们提出了一种基于云的方法来识别影响农业用地的karuvelam树。该系统由一个装置组成,该装置可以从图像中识别卡鲁velam树叶,检索GPS位置并更新云。数据在云中处理,指令通过物联网板传递给化学喷洒装置,以杀死杂草。我们的项目旨在设计一个原型,以证明我们开发的用于识别karuvelam树的代码在实际系统中运行良好。这一概念可以通过日本设计的OPTiM农业无人机(对选定杂草进行自动除草剂喷洒)应用于现实世界。

Computational Analysis of the Effect of Change in Leading Edge Radius, Blending Distance from the leading edge and their combined effect on a standard NACA 0012 aerofoil 前缘半径变化、前缘混合距离及其综合效应对标准NACA 0012型翼型影响的计算分析

aerofoil is the cross-sectional shape obtained when a wing is brought in perpendicularity with a plane. The aerofoil used is the NACA 0012 symmetric aerofoil, alterations are duly made in order to analyse the flow pattern such as altering the leading-edge radius or the blending distance or both simultaneously in addition to change in angle of attack. This paper deals with the fundamental equations associated with the generation of NACA aerofoils. The aerofoil generation is done using MATLAB. Certain elementary changes are then made in the wing geometry and their respective changes are studied through their effects on the characteristic aerodynamic configuration of the aerofoil. Since the aerofoil chosen is symmetric the changes in the aerodynamic properties can be easily studied and their variation can be easily understood. These aerodynamic characteristics are studied by the non-dimensional flow parameters such as Cl, Cd and Cm
翼型是当机翼与平面垂直时获得的横截面形状。所使用的翼型是NACA 0012对称翼型,改变是适当的,以分析流动模式,如改变前缘半径或混合距离或两者同时除了改变迎角。本文讨论了与NACA翼型产生有关的基本方程。利用MATLAB实现了翼型的生成。然后对机翼几何形状进行了一些基本的改变,并通过对翼型特征气动结构的影响来研究它们各自的变化。由于所选择的翼型是对称的,因此气动性能的变化可以很容易地研究和理解。采用无量纲流动参数Cl、Cd和Cm对这些气动特性进行了研究

Study on H.265/HEVC against VP9 and H.264 : On Space and Time Complexity for Codecs H.265/HEVC对VP9和H.264的研究:关于编解码器的时空复杂度
Jay Sharma, T. Choudhury, S. Satapathy, A. Sabitha
The study analyzes H.265 video compression standard against its predecessor H.264 and Google’s developed VP9. A review of the recent developments in H.265/HEVC standardization have been provided. Analysis takes place using samples of uncompressed videos (frames) subjected to these 3 standards in FFmpeg command line tool with application of different containers. Further, these encoded compressed video samples are the ones which are analyzed on the basis of SCR, SS, bandwidth, size, time, efficiency and practicality. High Efficiency Video Coding (HEVC) is the proposed new generation of video compression standard, which enables substantially higher compression capability than the existing standards and exhibits superior coding performance improvements over its predecessors. Compression performance is owed to quad-tree structure, parallel encoding/decoding (codec), intra-prediction modes, integer transforms etc. With the right codec, multimedia companies could save millions on storage while keeping the quality intact, thereby increasing throughput and profits. Cost efficiency is performed with respect to the business development.
该研究将H.265视频压缩标准与其前身H.264和谷歌开发的VP9进行了分析。本文综述了H.265/HEVC标准化的最新进展。在FFmpeg命令行工具中使用不同容器,使用符合这3个标准的未压缩视频(帧)样本进行分析。并对编码后的压缩视频样本进行了SCR、SS、带宽、大小、时间、效率和实用性等方面的分析。高效视频编码(High Efficiency Video Coding, HEVC)是新一代的视频压缩标准,它比现有的标准具有更高的压缩能力,并且在编码性能上比之前的标准有了更大的改进。压缩性能归功于四叉树结构、并行编码/解码(编解码器)、内部预测模式、整数变换等。有了正确的编解码器,多媒体公司可以在保持质量不变的情况下节省数百万美元的存储费用,从而提高吞吐量和利润。成本效率是在业务发展方面执行的。

S. Moitra, P. Bhowmik, A. Muvvala
Design of a 150° bent HMSIW filter using T-slots is furnished in this paper. Microstrip to SIW transitional feeding technique is used at both at input and output ports over a material with dielectric constant of 3.2 and thickness 0.8. Array of five and nine T-slots are integrated over the HMSIW structure to achieve the band-pass property. The insertion loss is found to be 0.84dB. The design steps are discussed and it has been shown that the transmission pass-band can be shifted at other frequency bands by changing the parameters of the T-slots. Wideband response is obtained by using the technique within the microwave X and Ku frequency bands. The filter configurations presented in this paper are concise, cost effective and easily fabricable.

Chronic Kidney Disease Detection Using Back Propagation Neural Network Classifier 基于反向传播神经网络分类器的慢性肾脏病检测
B. Ravindra, N. Sriraam, M. Geetha
Chronic kidney disease (CKD) often referred to as chronic kidney failure considered to be life threatening disease due to huge deposition of electrolytes, fluids and waste in our body. There is a huge need to differentiate non chronic disease (NCKD) from CKD to recognize the health status of any subject visiting the nephrology clinics. This study makes use of artificial neural network (ANN) based classification of CKD and NCKD. Four attributes, Creatinine, Urea, Sodium and potassium were considered to diagnose the patient suffering from CKD or not. Datasets collected from local general hospital with n=230 was used. A feedforward back propagation neural network (BPNN) model was employed for classification and the performance of BPNN classifier was evaluated using sensitivity, specificity and classification accuracy. The Datasets was initially mined using clustering to decide the valid attribute values. The simulation results shows an overall classification accuracy 95.3% to distinguish subject suffering with CKD from NCKD.
慢性肾脏疾病(CKD)通常被称为慢性肾衰竭,被认为是危及生命的疾病,由于大量的电解质,液体和废物沉积在我们的身体。有巨大的需要区分非慢性疾病(NCKD)和CKD,以识别任何访问肾脏科诊所的受试者的健康状况。本研究利用人工神经网络(ANN)对CKD和NCKD进行分类。肌酐、尿素、钠、钾四项指标是诊断患者是否患有CKD的标准。数据来自当地综合医院,共230例。采用前馈反馈传播神经网络(BPNN)模型进行分类,并从灵敏度、特异性和分类精度三个方面评价了BPNN分类器的性能。最初使用聚类来挖掘数据集以确定有效的属性值。仿真结果表明,区分慢性肾病和非慢性肾病的总体分类准确率为95.3%。

Addressing Challenges of Hadoop for BIG Data Analysis 解决Hadoop在大数据分析中的挑战
R. Khullar, Tushar Sharma, T. Choudhury, R. Mittal
Data has become necessary part of every individual, industry, economy, business function and organization. Miscellaneous industries, machines and institutions are expanding their analytical data at digital world at a very high rate. As this data set increases, selecting the relevant information becomes a laborious task. Therefore, this on-command and on-demand nature of digital universe gives creation of a data category called the Big-Data because of its sheer velocity, volume and variety. It is basically employed to differentiate the various datasets and their sizes are above the ability of the database software tools to manage, evaluate and store. It proposes exclusive computational and analytical challenges which includes measurement errors, scalability and storage bottleneck and noise accumulation.Because of a specific characteristic of the Big-Data they are put in a distributed file system Hadoop (HDFS). However, Hadoop is impartially complex. As Hadoop is new to users, this research paper discusses the important challenges and issues faced during the data mining and deployment of the file system. Aim of this paper is to make user comfortable with Hadoop.
数据已经成为每个人、行业、经济、业务功能和组织的必要组成部分。各种各样的行业、机器和机构正在以非常高的速度扩展他们在数字世界的分析数据。随着数据集的增加,选择相关信息成为一项费力的任务。因此,数字宇宙的这种随需应变的特性创造了一种被称为大数据的数据类别,因为它的速度、数量和种类都非常多。它基本上是用来区分各种数据集,它们的大小超出了数据库软件工具的管理、评估和存储能力。它提出了独特的计算和分析挑战,包括测量误差,可扩展性和存储瓶颈以及噪声积累。由于大数据的特定特性,它们被放在分布式文件系统Hadoop (HDFS)中。然而,Hadoop相当复杂。由于Hadoop对用户来说是新的,本研究论文讨论了在数据挖掘和文件系统部署过程中面临的重要挑战和问题。本文的目的是让用户熟悉Hadoop。
