ITT Exelis has built and operates the Surveillance Broadcast Services (SBS) system to provide the Federal Aviation Administration (FAA) with Automatic Dependent Surveillance - Broadcast (ADS-B) target data in the U.S. National Airspace System (NAS). The system requirements for significant coverage at low altitudes demands a dense laydown of radio stations such that at moderate and high altitudes there is an abundance of overlapping coverage from multiple radio stations. While such redundancy is generally a good attribute, the future expected growth in ADS-B equipage will place a large burden on the SBS network and servers because of that redundancy. In order to proactively mitigate that traffic growth, the SBS is designed with a number of traffic management features to control the amount of redundant reports from multiple radio stations. This paper summarizes a study that projects the impact of the growth in ADS-B equipped traffic on the SBS system, and evaluates the effectiveness and adequacy of existing and new candidate network traffic management features under consideration in the SBS.
ITT Exelis公司建立并运营监视广播服务(SBS)系统,为美国联邦航空管理局(FAA)提供美国国家空域系统(NAS)中的自动相关监视广播(ADS-B)目标数据。为了在低空地区实现广泛覆盖,系统要求密集地布置无线电台,以便在中等和高海拔地区有大量来自多个无线电台的重叠覆盖。虽然这种冗余通常是一个好的属性,但是ADS-B设备的未来预期增长将给SBS网络和服务器带来很大的负担,因为这种冗余。为了主动缓解流量增长,SBS设计了许多流量管理功能,以控制来自多个无线电台的冗余报告的数量。本文总结了一项研究,该研究预测了配备ADS-B的流量增长对SBS系统的影响,并评估了SBS中考虑的现有和新的候选网络流量管理功能的有效性和充分性。

This article shows how the problem of autonomous navigation of a small boat was formulated and solved. The boat is a catamaran equipped with two water wheels driven by DC motors. A look-up table controller is used to turn on and off the DC motors. Firstly it is shown how the Kalman filter algorithm was applied to estimate in real-time the boat position and heading, using the measurements from a low-cost IMU (Inertial Measurement Unit), a standard GPS receiver and a digital compass. Then a mathematical model of the boat and simulation results for the sensor integration problem and for the boat controller, are discussed. Finally, the article shows how the proposed solution for the autonomous navigation problem was implemented and tested using an embedded computer and the sensors (IMU, GPS receptor and digital compass) aboard the boat.

Planet scale growth in deployment of mobile and interconnected devices interacting in a participatory sensing, collection and dissemination of information, have motivated interest in the Internet of Things. Therefore, the problem of information overload and big data becomes inherent. In this paper we intend to propose a methodology aiming at a lower processing overhead towards an energy efficient method for networking of information in larger systems. We consider a content-centric networking paradigm that is aimed at enhancing the dissemination of information and eliminating many problems of host based communication. The proposed method is based on a network coding approach which leverages the spectral characteristics of network topology. We argue that topology of interacting nodes within a cluster can influence the performance of network coding from a computational complexity perspective and therefore the overall energy consumption in a system. We propose an algorithm that takes an opportunistic strategy to utilize the social structure and spectral characteristics of the network topology based on our design of a multicast coding network that reduces the number of encoding nodes.
在参与式感知、信息收集和传播中,移动和互联设备的部署在全球范围内不断增长,激发了人们对物联网的兴趣。因此,信息超载和大数据问题成为必然。在本文中,我们打算提出一种方法,旨在降低处理开销,以实现大型系统中信息联网的节能方法。我们考虑了一个以内容为中心的网络范例,它旨在增强信息的传播并消除基于主机的通信的许多问题。该方法基于一种利用网络拓扑的频谱特性的网络编码方法。我们认为,从计算复杂性的角度来看,集群内相互作用节点的拓扑结构会影响网络编码的性能,从而影响系统中的总体能耗。基于我们设计的减少编码节点数量的组播编码网络,我们提出了一种利用网络拓扑的社会结构和频谱特征的机会策略的算法。

Improving system reliability in optical networks by failure localization using evolutionary optimization 基于进化优化的光网络故障定位方法提高系统可靠性

This paper proposes a novel approach for cost-effective link failure localization in optical networks in order to improve the reliability of telecommunication systems. In such failure localization problems the optical network is usually represented by a graph, where the task is to form connected edge sets, so-called monitoring trails (m-trails), in a way that the failure of a link causes the failure of such a combination of m-trails, which unambiguously identifies the failed link. Every m-trail consumes a given amount of resources (like bandwidth, detectors, amplifiers, etc.). Thus, operators of optical network may prefer a set of paths, whose paths can be established in an easy and cost-effective way, while minimizing the interference with the route of the existing demands, i.e. may maximize the revenue. In this paper, unlike most existing techniques dealing with failure localization in this context, the presently proposed method considers a predefined set of paths in the graph as m-trails. This way the task can also be formulated as a special Set Covering Problem (SCP), whose general form is a frequently used formulation in a certain type of operations research problems (e.g. resource assignment). Since for the SCP task evolutionary algorithms, like Ant Colony Optimization (ACO), has been successfully applied in the operations research field, in this work the failure localization task is solved by using ACO on the SCP formulation of the described covering problem, which is a rather unique combination of approaches of different fields (telecommunication, operations research and evolutionary computation) placing our investigation in the multi-field scope of complex systems.
为了提高通信系统的可靠性,本文提出了一种经济有效的光网络链路故障定位方法。在这种故障定位问题中,光网络通常用一个图来表示,其中的任务是形成连接的边缘集,即所谓的监测轨迹(m-trails),以一种链路故障导致m-trails组合失效的方式,这种组合可以明确地识别故障链路。每条m-trail都消耗一定数量的资源(如带宽、检测器、放大器等)。因此,光网络运营商可能会选择一组路径,这些路径可以以一种简单、经济的方式建立,同时对现有需求的路由干扰最小,即可以实现收益最大化。在本文中,与大多数现有的处理这种情况下故障定位的技术不同,目前提出的方法将图中的一组预定义路径作为m-trails。这样,任务也可以表述为一个特殊的集合覆盖问题(SCP),其一般形式是某一类运筹学问题(如资源分配)中经常使用的表述。由于蚁群优化(Ant Colony Optimization, ACO)等SCP任务进化算法已成功应用于运筹学领域,本研究采用蚁群优化算法对所描述的覆盖问题的SCP表述进行故障定位任务求解,这是一种不同领域(电信、运筹学和进化计算)方法的独特结合,将我们的研究置于复杂系统的多领域范围内。

In the Biomedical Engineering field exist many issues with electronic medical devices repairing process especially when the problem is intermittent. In other words, the device works fine for some periods of time and it fails in other ones, which becomes challenge for biomedical departments to diagnose and fix the problems. When the device issues a constant and verifiable problem, technicians can rapidly proceed with the repairing of the unit, replacing bad components and performs the required tests before return the unit repaired to the customers. But, the most relevant issue, which is matter of this paper, is the event when a unit comes for repair with an intermittent problem issue stated. This is the case when, after a testing period of time, the failure is not verified in the biomedical workshop or in the lab, and then the biomedical device is returned to the customer (hospital, healthcare provider or medical center) with a diagnostic note stating “no problem found” (NPF). Once the returned unit is in the healthcare provider, it is available and ready for use; a doctor or practitioner request the unit for a medical procedure, and is when the intermittent problem show up again producing the obvious customer disgust. Then, the customer re-sends the unit to the repair center one more time for servicing, incurring a wasting of resources such as, labor time, shipping and handling costs, etc. and what is worst, bad customer satisfaction record. One of the solutions is be to have the biomedical device running continually for hours or maybe days and, at the same time one of the biomedical technician must be present until the issue be verified and confirm the problem; this is a no adequate solution, because mainly, it is so difficult to have a person at front of a device to monitor it by a long period of time. The other way is to do the same thing but in determined period of time, which could cause that the intermittent problem occurs exactly when the monitoring is missed and get a false NPF diagnostic again. Along this paper, we will describe our proposal with a valid solution to this problem, based on our experience in the biomedical engineering field and with the use of error codes which are internally generated for every biomedical device when they detect some type of failure. Our solution is developed to be used in a mobile device (Android technology) with the choice to be installed in other mobile technologies such as, iPhone, PDM, etc. Our solution to this problem is to provide a freely available database of medical devices, their error codes, what they mean, and how to fix the problems if there is one. This database will be populated with the data provided by the users, and will be approved by the administrator or moderator of the site to prevent malicious information. We believe that the benefits of having a global information source will be motivation for users of the site to take the time to add their knowledge when the site lacks it.
在生物医学工程领域,电子医疗器械的修复过程中存在着许多问题,特别是间歇性修复问题。换句话说,该设备在某些时间段工作正常,而在其他时间段则出现故障,这成为生物医学部门诊断和解决问题的挑战。当设备出现持续且可验证的问题时,技术人员可以迅速进行设备的维修,更换损坏的部件并执行所需的测试,然后将维修后的设备退还给客户。但是,最相关的问题,也是本文的主题,是当一个单元来维修时出现间歇性问题的事件。这种情况是,经过一段时间的测试后,在生物医学车间或实验室中没有验证故障,然后将生物医学设备退还给客户(医院、医疗保健提供商或医疗中心),并附上“未发现问题”(NPF)的诊断说明。一旦送回的设备送到医疗保健提供者处,它就可以使用了;医生或从业人员要求该单位进行医疗程序,当间歇性问题再次出现时,会产生明显的客户厌恶。然后,客户再次将设备送到维修中心进行维修,造成了人力时间、运输和处理成本等资源的浪费,最糟糕的是,造成了糟糕的客户满意度记录。解决方案之一是使生物医学设备连续运行数小时或数天,同时必须有一名生物医学技术人员在场,直到问题得到核实和确认;这是一个不充分的解决方案,因为主要是很难让一个人在设备前长时间地监控它。另一种方法是在确定的时间段内执行相同的操作,这可能导致间歇问题恰好在错过监视时发生,并再次得到错误的NPF诊断。在本文中,我们将根据我们在生物医学工程领域的经验,并使用每个生物医学设备在检测到某种类型的故障时内部生成的错误代码,描述我们的建议,并提供有效的解决方案。我们的解决方案是为移动设备(Android技术)开发的,可以选择安装在其他移动技术中,如iPhone, PDM等。我们对这个问题的解决方案是提供一个免费的医疗设备数据库,包括它们的错误代码、它们的含义以及如何解决问题(如果有的话)。该数据库将由用户提供的数据填充,并将由站点的管理员或版主批准,以防止恶意信息。我们相信,拥有全球信息源的好处将激励网站用户在网站缺乏知识时花时间增加他们的知识。

To increase flexibility in intralogistics, decentralized controlled material handling systems have been developed. We investigate the suitability of one of these systems, the FlexConveyor, for sorting of goods. The FlexConveyor is a material handling system built out of multiple, identical modules, each equipped with a controller. By communicating with each other, the modules are able to cooperate and to transport goods from any source to its specific destination. For sorting of goods, densely connected layouts promise high throughput while requiring little space. To compare different layouts, to identify bottlenecks and to draw conclusion about algorithm optimizations, we do a layout analysis partially based on methods coming from the network analysis of national transportation networks. The results of this layout analysis are compared to experimental results of a discrete event simulation model.

Joint route planning for UAV and sensor network for data retrieval 面向数据检索的无人机与传感器网络联合航路规划

Large scale data gathering from remote sensor networks is a key issue in many remote deployments. Manual data collection is difficult and sending ground robots to collect information can be complex due to uneven terrain. Alternately, unmanned aerial vehicle (UAV) can be used to collect data from sensor networks. The UAV will fly over the sensors gathering the data. However, to minimize the flight time of the UAV and maximize the network lifetime, a joint route optimization for UAV and sensor network must be carried out. Additionally, the UAV has kinematic constraints and communication range limitations. Determining solution with these constraints is difficult and computationally intensive. In this paper, we propose a heuristic solution by decoupling the problem into four sub-problems. The first is to determine clusters of sensors with communication range limitations. The second is to efficiently connect the clusters.

在许多远程部署中,从遥感网络中大规模采集数据是一个关键问题。人工采集数据困难,由于地形不平坦,派遣地面机器人采集信息可能会很复杂。另外,无人驾驶飞行器(UAV)可以用于从传感器网络收集数据。无人机将飞越传感器收集数据。然而,为了最小化无人机的飞行时间和最大化网络寿命,必须对无人机和传感器网络进行联合航路优化。此外,无人机具有运动学约束和通信距离限制。确定具有这些约束的解是困难的,并且计算量很大。在本文中,我们提出了一种启发式解决方案,将问题解耦为四个子问题。首先是确定具有通信范围限制的传感器集群。二是高效连接集群。三是设计集群内部的路径,使信息收集最大化;四是为无人机设计路径规划器,进行数据收集。我们通过一个例子来展示所提出的解决方案。

Manual data collection is difficult and sending ground robots to collect information can be complex due to uneven terrain. Alternately, unmanned aerial vehicle (UAV) can be used to collect data from sensor networks. The UAV will fly over the sensors gathering the data. However, to minimize the flight time of the UAV and maximize the network lifetime, a joint route optimization for UAV and sensor network must be carried out. Additionally, the UAV has kinematic constraints and communication range limitations. Determining solution with these constraints is difficult and computationally intensive. In this paper, we propose a heuristic solution by decoupling the problem into four sub-problems. The first is to determine clusters of sensors with communication range limitations. The second is to efficiently connect the clusters.

This paper discusses contemporary military operations concepts, based on a systems approach. These concepts include the U.S. effects-based operations (EBO), NATO's effects-based approach to operations (EBAO) and comprehensive approach (CA) and Israel's systemic operational design (SOD). The paper describes the concepts, reviews the critique of these concepts and discusses the critique from the systems perspective. A systems engineering framework is used as a structure for discussion. The paper is an exploratory type of research which aims to provide fresh insights regarding the challenges and failings of the concepts under discussion. Hence, the contribution of the paper is contextual in nature. The findings of the paper suggest that the expectations for the systems approach to help solve the needs of the military community have perhaps been too ambitious. The chosen systems method, systems analysis and systems techniques for these concepts are probably too limited to be able to support the creation of a holistic understanding of the operational environment.
本文基于系统方法讨论了当代军事行动概念。这些概念包括美国基于效果的作战(EBO)、北约基于效果的作战方法(EBAO)和综合方法(CA)以及以色列的系统作战设计(SOD)。本文描述了这些概念,回顾了对这些概念的批判,并从系统的角度对这些批判进行了讨论。系统工程框架被用作讨论的结构。本文是一种探索性研究,旨在为讨论中的概念的挑战和失败提供新的见解。因此,论文的贡献是上下文的性质。论文的研究结果表明,对帮助解决军事社区需求的系统方法的期望可能过于雄心勃勃。为这些概念所选择的系统方法、系统分析和系统技术可能太过有限,无法支持创建对操作环境的整体理解。

To remain competitive, industrial plant manufacturers need to increase their engineering performance. This requires an assessment of engineering performance first. Since engineering is connected in multiple ways to other disciplines, stages in the value-add chain and phases of the plant life cycle such an assessment proved to be difficult. This contribution presents a pragmatic model to systematize subjective interpretations of engineering performance in order to support plant manufacturers to achieve a holistic and comprehensive picture of engineering performance. It further aims to increase the awareness of plant manufacturers for weaknesses of current performance assessment approaches. The contribution is based on a literature review and qualitative indepth expert interviews, which results have been validated and prioritized in a web-based quantitative survey. Current economic considerations turned out to be not suitable to assess engineering performance, since they have been developed for physical goods or have a strong focus on costs. Based on best-practice sharing, case studies and expert interviews a model was developed which supports plant manufacturers to structure performance and to illustrate challenges and weaknesses of current assessments. The presented model breaks engineering performance down into three dimensions. The subjective interpretations of performance were considered by two perspectives.
为了保持竞争力,工业设备制造商需要提高他们的工程性能。这需要首先对工程性能进行评估。由于工程以多种方式与其他学科、增值链的各个阶段和工厂生命周期的各个阶段相关联,因此这种评估被证明是困难的。这一贡献提出了一个实用的模型,系统化工程性能的主观解释,以支持工厂制造商实现工程性能的整体和全面的画面。它还旨在提高工厂制造商对目前业绩评估方法的弱点的认识。贡献是基于文献综述和定性深度专家访谈,其结果已在基于网络的定量调查中得到验证和优先排序。目前的经济考虑被证明不适合评估工程性能,因为它们是为实物产品开发的,或者是对成本的强烈关注。在最佳实践分享、案例研究和专家访谈的基础上,开发了一个模型,该模型支持植物制造商构建绩效并说明当前评估的挑战和弱点。该模型将工程性能分解为三个维度。表现的主观解释从两个角度来考虑。
