Electronic capture of patient records, including digital imaging, facilitates: i) collaboration and communication between providers and entities involved in patient care, ii) compilation of lifetime patient histories that are more accessible to treating physicians, and iii) aggregation of population data for evidence-based medicine and creation of decision support tools. The Medicare and Medicaid electronic health record (EHR) Incentive Programs and associated Meaningful Use (MU) requirements are a driving force in the evolution towards digitized patient recordkeeping. For the foreseeable future, MU will continue to exert pressure on EHR vendors, hospitals, and ambulatory practices to conform to increasingly stringent government reporting requirements or else face obsolescence and/or reduced fees for services. This is encouraging many practices - including radiology and digital imaging centers - that may have opted out of MU compliance in the past - to re-examine how they integrate their work flows with EHR systems and with other physicians and treatment facilities. This paper describes digital imaging technology and strategies to interface and integrate it with EHR systems and clinical work flows. A case study based on the open source electronic health record software, OpenEMR, is presented as an illustrative example of challenges integrating imaging and EHR technology across and between clinical practices. The case study demonstrates how poor EHR integration with picture archiving and communication systems (PACS) and radiology information systems (RIS) complicates and adds to the clinician work flow and reduces the diagnostic value of imaging data. EHR, PACS, and RIS vendors need to improve system interoperability and image sharing capabilities in their product offerings. Better, more complete standards are needed to enable this to happen. DICOM, HL7, IHE, and other standards are evolving to address gaps in data integration and continuity across the spectrum of health information technology used in patient care. This will alleviate burdens on healthcare professionals and information technology staff who must use and implement systems infrastructure while maintaining compliance with Meaningful Use (MU) and Health Insurance Portability and Accountability Act (HIPAA). This is essential to achieving technology's promise of optimized healthcare delivery.
以电子方式获取患者记录,包括数字成像,有助于:i)参与患者护理的提供者和实体之间的协作和沟通,ii)编纂患者终生病史,使治疗医生更容易获得,以及iii)为循证医学收集人口数据,并创建决策支持工具。医疗保险和医疗补助电子健康记录(EHR)激励计划和相关的有意义使用(MU)要求是向数字化患者记录保存演变的推动力。在可预见的未来,MU将继续对电子病历供应商、医院和门诊诊所施加压力,要求他们遵守日益严格的政府报告要求,否则将面临过时和/或降低服务费用。这鼓励了许多实践,包括放射学和数字成像中心,他们过去可能选择不遵守MU,重新审视他们如何将自己的工作流程与EHR系统以及其他医生和治疗机构整合在一起。本文描述了数字成像技术以及与电子病历系统和临床工作流程接口和集成的策略。一个基于开源电子健康记录软件OpenEMR的案例研究作为一个说明性示例,展示了在临床实践中以及在临床实践之间集成成像和电子病历技术所面临的挑战。该案例研究表明,EHR与图像存档和通信系统(PACS)和放射信息系统(RIS)的不良集成如何使临床医生的工作流程变得复杂和增加,并降低了成像数据的诊断价值。EHR、PACS和RIS供应商需要改进其产品中的系统互操作性和图像共享能力。要实现这一点,需要更好、更完整的标准。DICOM、HL7、IHE和其他标准正在不断发展,以解决患者护理中使用的各种卫生信息技术在数据集成和连续性方面的差距。这将减轻医疗保健专业人员和信息技术人员的负担,他们必须使用和实施系统基础设施,同时遵守有意义使用(MU)和健康保险可移植性和责任法案(HIPAA)。这对于实现优化医疗保健服务的技术承诺至关重要。

In this work, an efficient digital system is designed using hardware to filter the Electrocardiogram (ECG) signal and to detect the QRS complex (beats). The system implementation has been done by using a Field Programmable Gate Array (FPGA). In the first phase of the hardware system implementation, Finite Impulse Response (FIR) filters are designed for preprocessing and denoising the ECG signal. The filtered signal is then used as the input of the second phase of the hardware implementation to detect and classify the ECG beats. The entire system has been implemented on ALTERA DE II FPGA by designing synthesizable finite state machines. Quartus II tool has been used to simulate and test the system. The designed system has been tested on ECG waves from the MIT-BIH Arrhythmia database by windowing the signal and applying adaptive signal and noise thresholds in each window of processing. The hardware system has achieved an overall accuracy of 98% in the beat detection phase, while providing the detected beats and the classification of irregular heart beat rates in real time.
在这项工作中,利用硬件设计了一个高效的数字系统来过滤心电图(ECG)信号并检测QRS复合体(心跳)。系统采用现场可编程门阵列(FPGA)实现。在硬件系统实现的第一阶段,设计了有限脉冲响应(FIR)滤波器对心电信号进行预处理和去噪。然后将滤波后的信号用作硬件实现第二阶段的输入,以检测和分类心电拍。通过设计可合成有限状态机,在ALTERA DE II FPGA上实现了整个系统。利用Quartus II工具对系统进行了仿真和测试。设计的系统已在MIT-BIH心律失常数据库的心电波上进行了测试,通过对信号进行窗口处理,并在每个处理窗口中应用自适应信号和噪声阈值。硬件系统在心跳检测阶段的总体准确率达到98%,同时实时提供检测到的心跳和不规则心率的分类。

Utilization of multiple mobile robots for map based RF access-point placement 多移动机器人在基于地图的射频接入点放置中的应用

This paper presents a way of collecting indoor RF propagation loss data utilizing multiple mobile robots collaborating through double-layered networks. The collected data are used to place wireless access points to maximize coverage with a minimum number of access points. A novel approach is used to navigate multiple robots using grid based maps which is a key issue in mobile robot utilization. Using grid based maps and range-finders to acquire surrounding information and match with a pre-populated information, robot locations are correctly identified. This resolved the problem of weak or no GPS signal in an indoor environment for position determination. The data acquisition strategy is studied without requiring a central source of timing and synchronization f or multiple robots. This is done using script-based robot command execution with exchange of request and response control messages. Lastly, numerical analysis of effects of navigation and data errors and their tolerances for proper interpretation of the collected data is presented.
本文提出了一种利用多个移动机器人通过双层网络协作收集室内射频传播损耗数据的方法。所收集的数据用于放置无线接入点,以使用最少数量的接入点最大化覆盖范围。提出了一种基于网格地图的多机器人导航方法,这是移动机器人利用中的一个关键问题。使用基于网格的地图和测距仪获取周围信息并与预先填充的信息相匹配,可以正确识别机器人的位置。这解决了在室内环境下定位时GPS信号微弱或无信号的问题。研究了不需要多个机器人的定时和同步中心源的数据采集策略。这是通过基于脚本的机器人命令执行以及请求和响应控制消息的交换来完成的。最后,对导航误差和数据误差的影响及其容限进行了数值分析,以便对所收集的数据进行正确的解释。

Automatic real time gait recognition based on spatiotemporal templates 基于时空模板的自动实时步态识别
Pub Date : 2015-05-01 DOI: 10.1109/LISAT.2015.7160196

Gait recognition is a biometric method used to recognize humans based on the style of their walk. In the last few years, wide varieties of gait recognition approaches have been proposed, and significant improvements have been made. Unlike other biometric methods, such as face and body recognition, gait recognition requires dealing with a large number of video frames. As a result, most of the successful gait recognition algorithms are computationally expensive and not applicable for real-time surveillance applications. This paper focuses on developing a framework for automatic gait recognition, and proposes a novel algorithm to create a 2D spatiotemporal gait template that is reliable for person recognition in real-time surveillance applications. A neural network is used for classification where the input is the spatiotemporal gait template. The complete gait recognition framework developed in this paper involves automatic detection and segmentation of the human body, alignment and registration, feature extraction, and classification.
步态识别是一种基于步态识别人类的生物识别方法。在过去的几年里,人们提出了各种各样的步态识别方法,并取得了显著的进步。与面部和身体识别等其他生物识别方法不同,步态识别需要处理大量的视频帧。因此,大多数成功的步态识别算法计算成本高,不适用于实时监控应用。本文重点研究了步态自动识别的框架,提出了一种新的算法来创建一个可靠的二维时空步态模板,用于实时监控应用中的人物识别。以时空步态模板为输入,利用神经网络进行分类。本文开发的完整的步态识别框架包括人体的自动检测和分割、对齐和配准、特征提取和分类。

The graph is a significant, considerable, and efficient representation of online courses in the computer based implementation of an educational system. E-learning and M-learning systems are modeled as weighted directed graphs where each node represents a course unit. The learning Path Graph represents and describes the structure of domain knowledge as well as the learning goals and all available learning paths.

Enhancing OAuth services security by an authentication service with face recognition 通过带有人脸识别的身份验证服务增强OAuth服务的安全性
Pub Date : 2015-05-01 DOI: 10.1109/LISAT.2015.7160208

Controlling secure access to web Application Programming Interfaces (APIs) and web services has become more vital with advancement and use of the web technologies. The security of web services APIs is encountering critical issues in managing authenticated and authorized identities of users. Open Authorization (OAuth) is a secure protocol that allows the resource owner to grant permission to a third-party application in order to access the resource owner's protected resource on their behalf, without releasing their credentials. Most web APIs are still using the traditional authentication which is vulnerable to many attacks such as man-in-the middle attack. To reduce such vulnerability, we enhance the security of OAuth through the implementation of a biometric service. We introduce a face verification system based on Local Binary Patterns as an authentication service handled by the authorization server. The entire authentication process consists of three services: Image registration service, verification service, and access token service. The developed system is most useful in securing those services where a human identification is required.
随着web技术的进步和使用,控制对web应用程序编程接口(api)和web服务的安全访问变得越来越重要。web服务api的安全性在管理经过身份验证和授权的用户身份时遇到了关键问题。开放授权(OAuth)是一种安全协议,它允许资源所有者向第三方应用程序授予权限,以便代表资源所有者访问受保护的资源,而无需释放其凭据。大多数web api仍然使用传统的身份验证,这很容易受到许多攻击,例如中间人攻击。为了减少这种漏洞,我们通过实施生物识别服务来增强OAuth的安全性。介绍了一种基于本地二进制模式的人脸验证系统,作为授权服务器处理的认证服务。整个身份验证过程包括三个服务:图像注册服务、验证服务和访问令牌服务。开发的系统在保护那些需要人工识别的服务方面最有用。

Alzheimer's (AD) is the most common form of dementia that negatively affects memory, thinking, behavior, and intellectual abilities in one's daily life. The risk of AD increases with age 65 and older although it may appear in people who are in their 40s or 50s. AD has no current cure. There are many ongoing research studies to understanding and treating this disease better. AD, a slowly progressive brain disease, begins well before clinical symptoms emerge. A diagnosis of AD is usually made by primary care physicians based on patient's medical and family history, psychiatric history, and history of cognitive and behavioral changes. Magnetic resonance imaging (MRI) is the most common imaging modality to use to identify brain changes. In this study, MRI scans of 10 individuals without AD and 10 individuals with AD are compared and analyzed based on brain volume. Measurements included the occipital lobe and hippocampal.
阿尔茨海默氏症(AD)是一种最常见的痴呆症,会对日常生活中的记忆、思维、行为和智力能力产生负面影响。老年痴呆症的风险随着年龄的增长而增加,尽管它可能出现在40多岁或50多岁的人群中。阿尔茨海默病目前尚无治愈方法。有许多正在进行的研究来更好地了解和治疗这种疾病。阿尔茨海默病是一种缓慢进展的脑部疾病,早在临床症状出现之前就开始了。阿尔茨海默病的诊断通常由初级保健医生根据患者的病史、家族史、精神病史以及认知和行为改变的历史做出。磁共振成像(MRI)是识别大脑变化最常用的成像方式。在本研究中,我们根据脑容量对10名AD患者和10名AD患者的MRI扫描结果进行了比较和分析。测量包括枕叶和海马。

As resilient as the human body may appear to be, the aging process is inevitable and takes a physical toll on all bodies, but getting older does not equate to neglecting healthy habits. If anything, as people age it is more important to be vigilant and lead proactive lifestyles. In an effort to increase health awareness and promote a healthier lifestyle Pace University conducted a 7 week pilot study using activity trackers and Telemedical Bluetooth devices. Most Senior citizens are intimidated and unaccepting when it comes to relying on technology but through the use of activity trackers senior citizens are able to measure their progress towards a healthier lifestyle. With the data gained from the activity trackers students will be able to monitor daily activity and assess whether or not it has encouraged a positive effect on senior vital data. This paper analyzes the impact of activity trackers on senior citizen biometric data including weight, blood pressure and pulse. By tracking the amount of steps the seniors have taken over the 7 week study. We will be able to determine if an increase in physical activity has a positive effect on the vital signs of older adults. Through the use of wireless technology, senior vital sings and step tracking data are synchronized wirelessly once a week by students at Pace University and measured for any significant changes. Prior to distributing activity trackers seniors were administered Pre assessment surveys and Post surveys, after receiving the trackers. Some of the collected data included preexisting health conditions, activity habits, and willingness to try new technology. By assessing the results, this paper explores whether the activity tracker had a significant effect on senior vital signs.
尽管人类的身体看起来很有弹性,但衰老的过程是不可避免的,对所有的身体都有伤害,但变老并不等于忽视健康的习惯。如果有什么区别的话,那就是随着人们年龄的增长,保持警惕和积极主动的生活方式变得更加重要。为了提高人们的健康意识,促进更健康的生活方式,佩斯大学使用活动追踪器和远程医疗蓝牙设备进行了一项为期7周的试点研究。大多数老年人对依赖科技感到害怕和不接受,但通过使用活动追踪器,老年人能够衡量他们朝着更健康的生活方式所取得的进展。通过从活动追踪器中获得的数据,学生将能够监控日常活动,并评估它是否对高级生命数据产生了积极影响。本文分析了运动追踪器对老年人体重、血压和脉搏等生物特征数据的影响。通过追踪老年人在7周的研究中所走的步数。我们将能够确定增加体育活动是否对老年人的生命体征有积极影响。通过使用无线技术,老年人的生命体征和步数跟踪数据每周由佩斯大学的学生无线同步一次,并测量任何重大变化。在发放运动追踪器之前,老年人在收到追踪器后进行了评估前调查和评估后调查。收集的一些数据包括先前存在的健康状况、活动习惯和尝试新技术的意愿。通过评估结果,探讨活动追踪器对老年人生命体征是否有显著影响。
