OO design for an IoT based automated plant watering system 基于物联网的自动化植物浇水系统的OO设计
Shrinidhi Rajagopal, V. Krishnamurthy
Plants make the world, a greener and a better place to live in. Although all plants need water to survive, giving them too much or too little can cause them to die. Thus, we need to implement an automatic plant watering system that ensures that the plants are watered at regular intervals, with appropriate amount, whenever they are in need. This paper describes the object oriented design of an IoT based Automated Plant Watering System.

Scene understanding — A survey 场景理解——调查
S. Aarthi, S. Chitrakala
In recent times, scene understanding holds a great position in computer vision due to its real time perceiving, analyzing and elaborating an interpretation of dynamic scene which leads to new discoveries. A scene is a view of real world environment with multiple objects and surfaces in a meaningful way. Objects are compact and act upon whereas scene are extended in space and act within. The visual information can be given with many features such as Colors, Luminance and contours or in the form of Shapes, Parts and Textures or through semantic context. The goal of scene understanding is to make machines look like humans, to have a complete understanding of visual scenes. Scene understanding is influenced by cognitive vision with an involvement of major areas like computer vision, cognitive engineering and software engineering. Due to its enormous growth many outstanding universities like Boston University, Stafford Vision lab, Scene grammar lab, air lab, Laboratory Machine Vision and Pattern Recognition have been perseveringly working for added improvements in this area. This paper discusses an extensive survey of scene understanding with various strategies and methods.
近年来,场景理解在计算机视觉中占有重要的地位,因为它能够实时地感知、分析和阐述动态场景,从而带来新的发现。场景是以一种有意义的方式呈现具有多个对象和表面的真实世界环境。物体是紧凑的,并对其产生作用,而场景则在空间上扩展,并在其中起作用。视觉信息可以用颜色、亮度和轮廓等多种特征来表示,也可以以形状、部件和纹理的形式表示,也可以通过语义上下文表示。场景理解的目标是让机器看起来像人类,对视觉场景有一个完整的理解。场景理解受到认知视觉的影响,涉及计算机视觉、认知工程和软件工程等主要领域。由于其巨大的增长,许多优秀的大学,如波士顿大学,斯塔福德视觉实验室,场景语法实验室,空气实验室,实验室机器视觉和模式识别一直在坚持不懈地为这一领域的进一步改进而努力。本文讨论了场景理解的各种策略和方法的广泛调查。

Analysis of modular biped wall climbing robot with high mobility and effective transit mechanism 具有高效移动机构的模块化双足爬壁机器人分析
S. Kamalakannan, R. Ambigai
Model and analysis of a wall climbing robot based on the link and suction mechanism. Many wall climbing robots are designed and shaped for few decades, but still, the underlying problems for the wall climbing are faced by the designers. Wall-climbing robots consist of a two mechanism, one is link and other is suction mechanism. In link mechanism there are two joints I-joint and T-joint, Where I-joint can rotate about its axis, T-joint can rotate about 180, Both the joints give the ability to rotate in clockwise and anticlockwise direction, which helps the robot to have a good transient mechanism between the horizontal wall to vertical wall. Based on these link mechanisms static and dynamic analysis were carried out to find the stress and strain developed in the joint during the motion. To achieve the suction mechanism, suction cups are placed on the suction base in a triangle shape and three suction cups are employed. Based on the weight of the robot load distribution is calculated. Both the static and dynamic analysis is performed using the software Ansys R15 and Inventry15.

Utilization based prediction model for resource provisioning 资源供应的基于利用率的预测模型
K. Rajaram, M. Malarvizhi
Resource provisioning refers to the selection, deployment and management of resources to ensure guaranteed performance for the applications. Efficient resource provisioning is a challenging problem since it is dynamic in nature and requires supporting applications with different performance requirements. In order to provide adequate resources for applications with different requirements that must satisfy expected performance, it is required to predict correct set of resources. Towards this objective, a prediction model for resource provisioning has been developed in this work. The prediction model is trained by the dataset that is created using a benchmark e-Commerce application namely TPC-W that is deployed in Amazon EC2 environment. The experimental results show that the prediction model based on Linear regression exhibits 70 percentage of accuracy, Support Vector Regression shows 68 percentage of accuracy, whereas Multilayer perceptron exhibits 90 percentage of accuracy for the same dataset.
资源发放是指选择、部署和管理资源,以保证应用程序的性能。高效的资源供应是一个具有挑战性的问题,因为它本质上是动态的,需要支持具有不同性能需求的应用程序。为了为具有不同需求且必须满足预期性能的应用程序提供足够的资源,需要预测正确的资源集。为实现这一目标,本工作建立了资源供应预测模型。预测模型通过使用部署在Amazon EC2环境中的基准电子商务应用程序(即TPC-W)创建的数据集进行训练。实验结果表明,对于同一数据集,基于线性回归的预测模型的准确率为70%,支持向量回归的准确率为68%,而多层感知器的准确率为90%。

Effective detection of mass abnormalities and its classification using multi-SVM classifier with digital mammogram images 基于数字乳房x线图像的多支持向量机分类器有效检测肿块异常并进行分类
G. Jothilakshmi, A. Raaza
Breast cancer is one of the most common kind of cancer, as well as it's the major cause in increasing mortality rate in women. Mammography is the effective method that is used for the early detection of breast cancer. Digital mammograms have become the most effective source for the detection of breast cancer. This paper proposes a method for the detection and classification of mass abnormalities in digital mammogram images using multi SVM classifier. The goal of this research is to increase the diagnostic accuracy of image processing and optimum classification between malignant and benign abnormalities in mass region which reduces the misclassification of breast images. Malignant and benign abnormalities are detected from the segmented images using region based segmentation, which correspond to the Regions of Interest (ROIs) or abnormal regions. Texture based features are extracted from the ROI samples using Gray Level Co-Occurrence Matrices (GLCMs). For the purpose of classification between malignant and benign samples, the optimum subset of texture features are classified using a Multi-Support Vector Machine (SVM). The effectiveness of this paper is examined using classification accuracy, which produced an accuracy of 94%.
乳腺癌是最常见的癌症之一,也是女性死亡率上升的主要原因。乳房x光检查是早期发现乳腺癌的有效方法。数字乳房x光检查已经成为检测乳腺癌最有效的来源。本文提出了一种基于多支持向量机分类器的数字乳房x线图像肿块异常检测与分类方法。本研究的目的是为了提高影像处理的诊断准确性和肿块区良恶性异常的最佳分类,减少乳房影像的误分类。使用基于区域的分割方法从分割后的图像中检测出恶性和良性异常,这些异常对应于感兴趣区域(roi)或异常区域。利用灰度共生矩阵(glcm)从ROI样本中提取基于纹理的特征。为了在恶性和良性样本之间进行分类,使用多支持向量机(SVM)对纹理特征的最佳子集进行分类。本文的有效性是用分类精度来检验的,它产生了94%的准确率。

A novel dual band microstrip patch antenna with DOS for X-band applications 用于x波段应用的新型双频微带贴片天线
R. Kiruthika, T. Shanmuganantham, Rupak Gupta
A Microstrip Patch antenna with two operating frequencies for radar application is presented. The antenna is modeled to resonate at two frequencies in X-band. The X-band frequency range lies between 8 to 12 Gigahertz and are mostly used in radar applications. The design consists of Defected Ground Structure (DGS) provided to improve the antenna performance. The dielectric substrate used by the antenna is of low cost FR4 (Flame Retardant) Epoxy. The Ansoft High Frequency Structural Simulator (HFSS) Version 12 software is used to analyze the results. The parameters like gain, return loss, directivity and bandwidth are discussed in the paper. With 9.19 GHz and 10.82 GHz as the resonant frequencies, a return loss of −22.91 dB and −40.99 dB is obtained with 540 MHz and 1600 MHz as the bandwidth respectively.

The Multilayer perceptron model is found to exhibit a better accuracy of 91.8 percentage.","PeriodicalId":269595,"journal":{"name":"2017 International Conference on Computer, Communication and Signal Processing (ICCCSP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127262433","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}
