Crowd counting plays a significant role in analyzing the crowd behavior in high density areas. Deep learning techniques may be utilized to count the crowd from given high density images. This gives situation awareness and facilitates in imposing necessary actions to control the crowd in various scenarios when needed. In this paper a deep convolutional neural network model has been developed for crowd counting. The model has been developed using VGG16 pre-trained model and it is tuned up for crowd counting using transfer learning. The dataset used in this work is ShanghaiTech crowd dataset, that contains 482 high density crowd images. Image augmentation is applied to enlarge the dataset. The model gives a training accuracy of 83% and 79% of validation accuracy.

C. Skanda, B. Srivatsa, B. S. Premananda
Communication at nano-scale provides high operational speed and low power consumption. Quantum-dot Cellular Automata (QCA) is used to create nano-scale digital logic circuits. It can replace CMOS technology in nano-scale due to the latter reaching its physical limit. Designing communication networks at nano-scale minimizes cost and energy dissipation. This study presents a QCA based crossbar switch and banyan network. The paper proposes the banyan network in single layer structure with energy and cost analysis. The work aims to minimize the cells, area, latency and energy dissipation in the banyan network. The proposed 2x2 crossbar switch has improvement of 55.44% in terms of cell count, and 93.12% in cost function compared to reference network. The designed 4x4 banyan network has a reduction of 54.18% in terms of cell count w.r.t. the reference networks. The networks are realized in the CAD tool QCA Designer 2.0.3 and energy analysis is performed in QCA Designer-E.

Distributed Ledger Systems to Improve Data Synchronization in Enterprise Processes 分布式账本系统改善企业流程中的数据同步
Jignesh Karia, Mukundan Sundararajan, G. Srinivasa Raghavan
Master Data Management (MDM) in enterprises deal with fixed data/information regarding different aspects of business that are considered single record of truth and form the basis for all business transactions. Enterprises manage their master data by several methods to ensure that it is a unique comprehensive representation of the entity by spending considerable resources in MDM but at the cost of time delays for updating the master data records or structure and with copies of the master data distributed across the enterprise units for operational needs that many times has modifications not reflected back into the master tables. Issues of delays in the master data updates lead to business impacts while the distributed nature of master data across an organization or organizations impacts data quality. Distributed ledger technology (DLT) is one approach that uses blockchain to obtain consensus to cut down the approval cycle time and the distributed nature makes it uniquely suited to manage synchronizing master data updates across the network of required users in the enterprise. Choice of correct business processes to benefit from using DLT for MDM is critical to obtain benefits from improvements. This paper shows a method to select from candidate business processes with coarse or fine process data and the value that can be gained from implementation of DLT for MDM.
企业中的主数据管理(MDM)处理有关业务不同方面的固定数据/信息,这些数据/信息被认为是单一的事实记录,并构成所有业务事务的基础。企业通过多种方法管理它们的主数据,以确保它是实体的唯一的全面表示,方法是在MDM中花费大量资源,但代价是更新主数据记录或结构的时间延迟,并且由于操作需要,主数据的副本分布在整个企业单元中,很多时候修改没有反映回主表中。主数据更新中的延迟问题会导致业务影响,而主数据在一个或多个组织中的分布式特性会影响数据质量。分布式账本技术(DLT)是一种使用区块链获得共识以缩短审批周期的方法,其分布式特性使其非常适合管理跨企业所需用户网络的同步主数据更新。选择正确的业务流程以受益于使用DLT进行MDM,这对于从改进中获得好处至关重要。本文展示了一种从具有粗流程数据或细流程数据的候选业务流程中进行选择的方法,以及可以从MDM的DLT实现中获得的价值。

Covariance Normalization and Bottleneck Features for Improving the Performance of Sleep Apnea Screening System 提高睡眠呼吸暂停筛查系统性能的协方差归一化和瓶颈特征
G. Mrudula, C. S. Kumar
Obstructive sleep apnea is a type of sleep disordered breathing (SDB), marked by pauses in breath during sleep. Sleep apnea monitoring devices are extremely expensive and unavailable in rural areas. The focus of this work is to develop a cost-effective sleep apnea screening system based on single channel electrocardiography (ECG) signal. Initially we built a baseline system that used heart rate variability information as input to a CNN classifier. The baseline system performance was evaluated for time domain (TD), frequency domain (FD), and TD and FD HRV features. The baseline model had an overall accuracy of 78.39%, specificity of 70.58% and sensitivity of 86.2%. In an attempt to increase the system performance, two methods were employed. Initially covariance normalization (CVN) was applied to the input features. CVN reduces the noisy factors induced to the input features due to patient specific variations. Subsequently we used neural networks to extract the bottleneck features (BNF) from bottleneck layer of the CNN model. This layer compresses the neural network, allowing the extraction of lower-dimensional information from the network. System performance was evaluated with the BNF extracted from the baseline model with HRV features as input, and also from the baseline model built using normalized HRV features. Upon performance evaluation, it was found that, compared to the baseline model, the BNF extracted from TD and FD HRV features shows a performance improvement of1.39%and BNF extracted from normalized TD and FD HRV features improved the overall accuracy by 1.7%.
阻塞性睡眠呼吸暂停是一种睡眠呼吸障碍(SDB),其特征是睡眠时呼吸暂停。睡眠呼吸暂停监测设备非常昂贵,在农村地区无法获得。本工作的重点是开发一种基于单通道心电图(ECG)信号的低成本睡眠呼吸暂停筛查系统。最初,我们建立了一个基线系统,使用心率变异性信息作为CNN分类器的输入。对基线系统性能进行时域(TD)、频域(FD)以及TD和FD HRV特征的评估。基线模型的总体准确率为78.39%,特异性为70.58%,敏感性为86.2%。为了提高系统性能,采用了两种方法。首先将协方差归一化(CVN)应用于输入特征。CVN减少了由于患者特定变化而引起的输入特征的噪声因素。随后,我们使用神经网络从CNN模型的瓶颈层提取瓶颈特征(BNF)。这一层压缩神经网络,允许从网络中提取低维信息。利用以HRV特征为输入的基线模型提取的BNF,以及使用归一化HRV特征构建的基线模型,对系统性能进行评估。性能评价发现,与基线模型相比,从TD和FD HRV特征中提取的BNF性能提高了1.39%,从归一化的TD和FD HRV特征中提取的BNF总体精度提高了1.7%。

DDoS Attack Detection in SDN Environment using Bi-directional Recurrent Neural Network 基于双向递归神经网络的SDN环境下DDoS攻击检测
Vinay Itagi, Mayur Javali, H. Madhukeshwar, Pooja Shettar, P. Somashekar, D. Narayan
Software Defined networking (SDN) is an emerging technology for effectively managing the network resources. SDN architecture has two planes namely control and data plane. Control plane manages the network using global view of the network topology and data plane helps routing and forwarding of packets. Centralised nature of controller poses security threats to SDN environment. Distributed Denial of Service (DDoS) attack is the most popular cyber attack which can cause economic loss due to network disruption. Thus, the design of DDoS detection system which can detect the attacks accurately in SDN environment is an important research issue. The purpose of this study is to develop a real-time method for detecting DDoS attacks using a bi-directional recurrent neural network (BRNN). We use deep learning models for the classification of DDoS attacks with real-time SDN data.Results demonstrated that BRNN has greater accuracy than feed forward neural network when we use Mininet emulator to create SDN environment.
软件定义网络(SDN)是一种有效管理网络资源的新兴技术。SDN架构有两个平面,即控制平面和数据平面。控制平面通过网络拓扑的全局视图对网络进行管理,数据平面实现报文的路由和转发。控制器的集中化特性给SDN环境带来了安全威胁。分布式拒绝服务(DDoS)攻击是最常见的网络攻击,它可以由于网络中断而造成经济损失。因此,设计能够准确检测SDN环境下DDoS攻击的检测系统是一个重要的研究课题。本研究的目的是开发一种使用双向递归神经网络(BRNN)检测DDoS攻击的实时方法。我们使用深度学习模型对实时SDN数据的DDoS攻击进行分类。利用Mininet仿真器创建SDN环境,结果表明BRNN比前馈神经网络具有更高的精度。

U. Nagesh, Manjunath Kotari, S. C. Chethan
Today the amount of importance given to waste management by the Municipal Corporation and public people created an unhygienic environment in the city leading to various deadly diseases. The garbage bins provided by municipality at public places are mismanaged due to poor information system and complete manual operations. Implementation of a clear communication system at either ends of the system will be a solution for a cleaner, hygienic city. In view of this, we propose and design an intelligent Smart Waste Management Using IoT. In this system we have deployed multiple garbage bins which are fitted with sensors modules and low cost embedded communicating devices to assist in tracking the level of waste in garbage container. The bins are identified by a unique identifier across the city so that it is easy to track the status of each container from an interactive web interface and a smart phone application. We integrate these networked smart bins to Google maps through suitable APIs to track them in real time. When the level reaches the preset threshold limit, the transmitter module will send the level along with unique ID of the bin through MQTT messages. This data can then be accessed by the concerned municipal authorities through interactive map and web applications and also immediate decision could be taken to track and reach them. We have also added several features such as bin tracking, nearest bin identification, remote garbage level indication etc.
今天,市政公司和公众对废物管理的重视程度在城市中造成了不卫生的环境,导致各种致命疾病。市政在公共场所提供的垃圾桶,由于信息系统不完善,人工操作过于繁琐,管理不善。在系统的两端实施一个清晰的通信系统将是一个更清洁、卫生的城市的解决方案。鉴于此,我们提出并设计了一种基于物联网的智能废物管理系统。在这个系统中,我们部署了多个装有传感器模块和低成本嵌入式通信设备的垃圾桶,以协助跟踪垃圾桶中的废物水平。垃圾箱在整个城市都有一个唯一的标识符,这样就可以很容易地通过交互式网络界面和智能手机应用程序跟踪每个容器的状态。我们通过合适的api将这些联网的智能垃圾箱集成到谷歌地图上,实时跟踪它们。当级别达到预设的阈值限制时,发送模块将通过MQTT消息发送级别和bin的唯一ID。然后,有关市政当局可以通过交互式地图和网络应用程序访问这些数据,也可以立即决定跟踪和联系他们。我们还增加了几个功能,如垃圾箱跟踪,最近的垃圾箱识别,远程垃圾水平指示等。

This application is designed to help people quit smoking and monitor their health. There are achievements at every stage that the user can take a moment to enjoy himself upon successful quitting. It is very helpful and useful tool as it gives the insights into forecasting and also a real-time notification approach incorporated. The user can continuously monitor his health and also feel how good it can be if he quits the smoking. The risk of Lung-Disease can be analyzed with the help of different parameter values by using different machine learning models. The risk is also shown on entering parameter values for thorasic-surgery. In the contained way, our project is mainly based on eradicating smoking and its related disorders by providing a helping hand to customers (an app/web app) to keep in check with the lung related disorders.
这个应用程序旨在帮助人们戒烟和监测他们的健康。每个阶段都有成就,用户可以在成功戒烟后享受一下。这是一个非常有用的工具,因为它提供了预测和实时通知方法的见解。用户可以持续监测自己的健康状况,并感觉戒烟有多好。通过使用不同的机器学习模型,可以借助不同的参数值来分析肺部疾病的风险。风险也显示在输入胸外科手术的参数值上。在包含方式上,我们的项目主要以根除吸烟及其相关疾病为基础,通过向客户提供帮助之手(app/web app)来检查肺部相关疾病。
