Multi-parameter patient monitor (MPM) uses vital signs, heart rate, blood pressure, oxygen saturation (SpO2) and respiration rate to identify the condition of patients. In this work, we use a support vector machine (SVM) backend classifier with four vital signs as its input and experimented using different kernels. It was observed that the SVM with a radial basis function kernel (SVM-RBF) outperforms the other kernels. Compared to non-linear SVMs, the linear SVM is computationally more efficient. Therefore, in this work we explore the use of feature mapping using locality constrained linear coding (LLC) to linearize the input features and thereby enhancing the performance of MPMs with a linear SVM (LLC-linSVM). To improve the performance further, we normalized LLC features by l2-norm (nLLC-linSVM). A performance improvement of 0.53% and 0.96% absolute for overall classification accuracy and specificity respectively was obtained over the baseline SVM-RBF system. However, a deterioration in the sensitivity was noted. To take advantage of both SVM-RBF and nLLC-linSVM, we finally fused the decision scores of both the systems. The fusion weights were estimated empirically using a dataset which is used neither for training nor testing. After decision fusion, we achieved a performance improvement of 0.90% absolute for classification accuracy, 0.24% absolute for sensitivity and 1.12% absolute for specificity compared to the baseline. All the systems were compared using receiver operating characteristics (ROC) and the results show that the performance of the fused system is better than the individual systems.
多参数患者监护仪(MPM)通过生命体征、心率、血压、血氧饱和度(SpO2)和呼吸频率来识别患者的病情。在这项工作中,我们使用支持向量机(SVM)后端分类器以四个生命体征作为输入,并使用不同的核进行实验。结果表明,基于径向基函数核(SVM- rbf)的支持向量机优于其他核。与非线性支持向量机相比,线性支持向量机的计算效率更高。因此,在这项工作中,我们探索了使用局部约束线性编码(LLC)的特征映射来线性化输入特征,从而通过线性支持向量机(LLC- linsvm)提高mpm的性能。为了进一步提高性能,我们使用l2-norm (nLLC-linSVM)对LLC特征进行了归一化。与基线SVM-RBF系统相比,总体分类精度和特异性的绝对提高分别为0.53%和0.96%。但是,注意到灵敏度的下降。为了充分利用SVM-RBF和nLLC-linSVM的优势,我们最终融合了两个系统的决策分数。使用既不用于训练也不用于测试的数据集对融合权重进行经验估计。决策融合后,与基线相比,我们实现了分类精度0.90%、灵敏度0.24%和特异性1.12%的绝对性能提高。采用接收机工作特性(ROC)对各系统进行了比较,结果表明融合系统的性能优于单个系统。

This paper presents an autonomous docking strategy for miniature spherical rolling robots. Due to their small physical size, these robots do not have onboard depth sensing capabilities, and have difficulty docking autonomously to a charging station. This docking/charging station has been augmented with a 2D LiDAR, which is used to scan the immediate area to detect the position of the robot; a waypoint is then calculated and transmitted via a low power wireless network. This forms a closed-loop position control system, eliminating any accumulated position errors due to odometry or heading drift. This novel system is able to detect a spherical robot, which is devoid of any distinct features, and more importantly does not require any depth or vision sensors to be installed on the miniature robot for the docking procedure. The described strategy is implemented and practical test results are illustrated.
提出了一种微型球形滚动机器人的自主对接策略。由于它们的物理尺寸小,这些机器人没有机载深度传感能力,并且难以自主对接到充电站。这个对接/充电站已经增强了一个2D激光雷达,用于扫描直接区域以检测机器人的位置;然后计算航路点并通过低功率无线网络传输。这形成了一个闭环的位置控制系统,消除了任何累积的位置误差,由于里程计或航向漂移。这种新颖的系统能够检测到一个没有任何明显特征的球形机器人,更重要的是不需要在微型机器人上安装任何深度或视觉传感器来进行对接过程。所述策略已实现,并给出了实际测试结果。

Climate change is challenging the current worldwide model of power generation. In this sense, European Union is promoting a deep transition collected in the 20-20-20 targets and the 2050 Energy Roadmap. These adjectives must be achieved by developing the use of clean, carbon-free energies, as it is the case of the renewableenergies and in particular of the ocean energy. The main problem with these kinds of energies is to reach a commercially mature stage so they can compete with conventional power sources. Therefore, it is crucial to reduce generation costs and increase the efficiency of the existing devices. With this regard, the work presents the modelling and experimental validation of the capture chamber of an Oscillating Water Column (OWC)-based powerplant. Although the study of the turbine and the generator may be considered a quite well-known matter, the control-oriented modelling of the capture chamber still deserves a further study to improve the power generation. In this work, a model obtained analytically of the OWC chamber is developed and numerically implemented. The model proposed is also validated and affords excellent results.
气候变化正在挑战目前世界范围内的发电模式。从这个意义上说,欧盟正在推动20-20-20目标和2050年能源路线图中收集的深度转型。这些形容词必须通过开发使用清洁、无碳的能源来实现,就像可再生能源,特别是海洋能源一样。这类能源的主要问题是达到商业成熟阶段,以便与传统能源竞争。因此,降低发电成本和提高现有设备的效率至关重要。在这方面,本文介绍了基于振荡水柱(OWC)动力装置的捕获室的建模和实验验证。虽然对水轮机和发电机的研究可能被认为是一个相当知名的事情,但捕获室面向控制的建模仍然值得进一步研究,以提高发电能力。本文建立了OWC燃烧室的解析模型,并进行了数值实现。所提出的模型也得到了验证,并取得了很好的结果。

Autism is a neurodevelopmental disorder that limits social, behavioral and communication skills of a child. Since early intervention can improve child's condition, early screening and diagnosis are necessary. Different tools were developed for screening, diagnosing and monitoring intervention. However, no tools have integrated all these steps and in developing countries, these discrete tools are not used due to lack of resources and expertise. Autism Express is an integrated cloud based framework that can perform screening, track diagnosis outcome, provide online parent counseling and monitor intervention progress automatically for 0–17 years old children. It includes a smart device based mobile application for autism screening. Then based on the outcome, the Virtual and Actual assessment processes confirm autism. For positive cases, it automatically activates parent counseling, connects resources and tracks intervention status for effective management. It is expected that the proposed system will bring positive changes in autism diagnosis, intervention and management processes especially in a resource limited setting and also raise awareness about it.
自闭症是一种神经发育障碍,它限制了儿童的社交、行为和沟通技能。由于早期干预可以改善儿童的状况,因此早期筛查和诊断是必要的。开发了用于筛查、诊断和监测干预的不同工具。然而,没有一种工具能够整合所有这些步骤,在发展中国家,由于缺乏资源和专业知识,这些分散的工具没有被使用。自闭症快车是一个基于云的集成框架,可以为0-17岁的儿童自动进行筛查、跟踪诊断结果、提供在线家长咨询和监测干预进展。它包括一个基于智能设备的自闭症筛查移动应用程序。然后根据结果,虚拟和实际评估过程确认自闭症。对于积极的案例,它会自动启动家长咨询,连接资源,跟踪干预状态,进行有效管理。预计所提出的系统将在自闭症诊断、干预和管理过程中带来积极的变化,特别是在资源有限的环境中,并提高对它的认识。

This research presents a redundant flight recovery system during a motor failure in an octocopter platform. This proposed recovery system exploits the property that the octocopter can be derived by combining two quadrotor systems. During motor failure, the octocopter switches to a stable quadrotor flight configuration while immediately landing the octocopter to prevent further damage to installed sensor and equipment and the octocopter platform. The redundant system utilizes PID and fuzzy logic controllers to stabilize altitude and attitude respectively.

Air pollution affects body organs and human systems in addition to the environment. Smart air pollution monitoring consists of wireless sensor nodes, server and a database to store the monitored data. Huge amounts of data are generated by gas sensors in air pollution monitoring system. Traditional methods are too complex to process and analyze the voluminous data. The heterogeneous data are converted into meaningful information by using data mining approaches for decision making. The K-Means algorithm is one of the frequently used clustering method in data mining for clustering massive data sets. In this paper, enhanced K-Means clustering algorithm is proposed to analyze the air pollution data. The correlation coefficient is calculated from the real time monitored pollutant datasets. The Air Quality Index (AQI) value is calculated from the correlation co-efficient to determine the air pollution level in a particular place. The proposed enhanced K-Means clustering algorithm is compared with Possibilistic Fuzzy C-Means (PFCM) clustering algorithm in terms of accuracy and execution time. Experimental results show that the proposed enhanced K-Means clustering algorithm gives AQI value in higher accuracy with less execution time for when compared to existing techniques.
空气污染除了影响环境外,还会影响身体器官和人体系统。智能空气污染监测由无线传感器节点、服务器和存储监测数据的数据库组成。空气污染监测系统中的气体传感器产生了大量的数据。传统方法过于复杂,无法处理和分析海量数据。利用数据挖掘方法将异构数据转化为有意义的信息,为决策提供依据。k -均值算法是数据挖掘中常用的聚类方法之一,用于对海量数据集进行聚类。本文提出了一种改进的K-Means聚类算法来分析大气污染数据。相关系数由实时监测的污染物数据集计算得出。空气质量指数(AQI)是由相关系数计算得出的,用以确定某一地区的空气污染程度。将改进的K-Means聚类算法与可能性模糊C-Means聚类算法在准确率和执行时间上进行了比较。实验结果表明,与现有算法相比,改进的K-Means聚类算法在提高AQI值精度的同时减少了执行时间。

Recently, high quality data transmission system has been widely researched. To achieve the better BER performance, several detection schemes in Multiple-Input Multiple-Output (MIMO) system have been studied. In the MIMO system, Maximum-Likelihood Detection (MLD) yields the optimal BER performance. However, it requires enormous computational complexity. Regarding the problem of actual implementation, Maximum-Likelihood (ML) Detection with QR Decomposition and M-algorithm (QRM-MLD) has been proposed for reducing the system complexity. On the other hand, this detection shows a little worse BER performance than MLD. Since QRM-MLD is used with a fewer symbol replica candidates than MLD, the error in the former detection stage causes an increase of the error in the latter stage. In this paper, we propose an optimal permutation of the channel matrix using QR Decomposition. The proposed scheme arranges channel matrix optimally, thereby absolute values of the diagonal components in upper triangular matrix are arranged ascending order. From the simulation results, the proposed scheme can improve the BER performance compared with the conventional method.
近年来,高质量的数据传输系统得到了广泛的研究。为了获得更好的误码率性能,研究了多输入多输出(MIMO)系统中的几种检测方案。在MIMO系统中,最大似然检测(MLD)可以获得最佳的误码率性能。然而,它需要巨大的计算复杂度。针对实际实现问题,提出了基于QR分解和m算法的最大似然(ML)检测(QRM-MLD)来降低系统复杂度。另一方面,该检测的误码率性能略低于MLD。由于QRM-MLD使用的符号副本候选数比MLD少,因此前一阶段的错误会导致后一阶段的错误增加。本文提出了一种基于QR分解的信道矩阵最优排列方法。该方案对信道矩阵进行最优排列,从而使上三角矩阵对角分量的绝对值按升序排列。仿真结果表明,与传统方法相比,该方案可以提高误码率。

This paper proposes a novel transformation for the design of two-dimensional (2D) finite impulse response (FIR) wideband filters with perfect circular symmetry. The proposed transformation is based on the kth order McClellan transformation and is found to be successful in generating precise circular contours even for wideband filters. The proposed method outperforms the state of the art transformations in terms of contour approximation accuracy. Design examples illustrate the effectiveness of the proposed transformation.

Image annotation aims to automatically predict a set of relevant keywords for an image that describe its semantics. Nearest Neighbor (NN) based methods have been successfully applied to address image annotation problems. In this paper,a novel method is introduced to improve the performance of annotating images. Firstly, we present a relevance feedback algorithm based on Multi-view non-negative matrix factorization (MultiNMF) to improve the retrieval performance during the process of querying the nearest neighbors. Secondly, a semantic co-occurrence (SC) based strategy is derived to effectively adjust the order of the annotated keywords. Experiment results on Corel5K dataset demonstrate that the proposed method outperforms those previous similar methods.
图像标注旨在自动预测一组描述图像语义的相关关键字。基于最近邻(NN)的方法已经成功地应用于解决图像标注问题。本文提出了一种提高图像标注性能的新方法。首先,提出了一种基于多视图非负矩阵分解(multiview non-negative matrix factorization, MultiNMF)的关联反馈算法,以提高最近邻居查询过程中的检索性能。其次,提出一种基于语义共现(SC)的标注策略,有效调整标注关键词的顺序;在Corel5K数据集上的实验结果表明,该方法优于以往的同类方法。

Balikbayan boxes sent by OFW's abroad are delivered by freight forwarders to their rightful recipients. But before arriving at the recipient's residence these packages pass through a series of transfers and transactions (foreign forwarder, shipping company, Bureau of Customs, local forwarder, etc.). In every transaction and transfer, the balikbayan box is vulnerable to different circumstances. The security of the items inside is at stake. I-Box (Innovated Balikbayan box Operation Express) is an innovation to the common delivery system that tracks and monitors the condition of the balikbayan box for secured delivery thus solving the flaws of the normal delivery system. A point to point implementation of this design enhances the monitoring and tracking of the boxes. The realized design uses RFID (Radio Frequency Identification) tags to monitor and track the exact location of the box that is unique to every box making the identification of the box non-reproducible.
海外海外工人寄往国外的“Balikbayan”箱子由货运代理送到合法的收件人手中。但在到达收件人住所之前,这些包裹要经过一系列的转移和交易(国外货代、船运公司、海关、当地货代等)。在每一笔交易和转移中,balikbayan盒子都容易受到不同情况的影响。里面物品的安全受到威胁。I-Box (innovative Balikbayan box Operation Express)是对普通快递系统的一种创新,通过跟踪和监控Balikbayan box的状态,实现安全配送,从而解决了普通快递系统的缺陷。本设计的点对点实现增强了对箱体的监控和跟踪。实现的设计使用RFID(无线射频识别)标签来监控和跟踪每个盒子的确切位置,这是唯一的,使盒子的识别不可复制。
