In disaster relief operations, lives can depend on timely location and safe removal of trapped and often injured people within damaged infrastructure (collapsed buildings, etc.). Further, these operations must be carried out without further collapsing structures within the environment. An emerging class of rope-like continuous backbone “continuum” robots provides new capabilities to address these critical operational problems. Continuum robots, also known as “robot trunks and tentacles”, can bend continuously along their structure, and are highly compliant. These features allow continuum robots to gently penetrate into congested spaces, navigating within complex and a priori unknown obstacle fields. This allows them to safely deploy sensors into collapsed structures, such as within debris in collapsed buildings, to assess conditions and potentially identify survivors. The further ability of these robots to use their bodies to perform whole arm grasping, wrapping safely around environmental objects, offers the possibility of using them as “active ropes” to gently pull victims out of such environments, while avoiding generation of large forces which might further collapse already damaged structures. We have developed a nine degree of freedom pneumatically actuated continuum robot, and deployed it to inspect within rubble piles and to gently grasp and retrieve human surrogates (dummies). Broader application of these kinds of “robot ropes” include remote inspection operations in Space and nuclear environments, as well as a variety of minimally invasive medical procedures.
在救灾行动中,能否及时找到并安全移走被困在受损基础设施(倒塌的建筑物等)内并经常受伤的人,可能会危及生命。此外,这些行动必须在不进一步破坏环境结构的情况下进行。一种新型的绳状连续骨干“连续体”机器人为解决这些关键的操作问题提供了新的能力。连续体机器人,也被称为“机器人躯干和触手”,可以沿其结构连续弯曲,具有很高的柔顺性。这些特性使连续体机器人能够缓慢地渗透到拥挤的空间中,在复杂和先验未知的障碍场中导航。这使他们能够安全地将传感器部署到倒塌的建筑物中,例如倒塌建筑物的碎片中,以评估情况并可能识别幸存者。这些机器人的进一步能力是使用它们的身体来执行整个手臂抓取,安全地包裹在环境物体周围,提供了使用它们作为“主动绳索”来轻轻地将受害者拉出这种环境的可能性,同时避免产生可能进一步坍塌已经损坏的结构的巨大力量。我们已经开发了一个九自由度气动连续机器人,并部署它检查碎石堆和轻轻地抓住和收回人类代理人(假人)。这类"机器人绳索"的更广泛应用包括空间和核环境中的远程检查操作,以及各种微创医疗程序。

We report on UAV(unmanned aerial vehicle)-based imaging missions over rice and corn fields in Isabela province in the Philippines. Spectral reflectance sensors were deployed for ground truthing, while aerial imagery were produced from RGB and NIR-retrofitted cameras. The ground truth sensors function as calibration points for extending the measurements over the whole imaged field. UAV-based missions deliver the high resolution and spatial scope required of imagery targeting mixed cropping regimes and multiple-farmer plots that have differing starting dates. The ledger-based monitoring systems currently employed by local government units to monitor and manage regional agriculture can be improved by such UAV imagery.

This paper presents a study of mobile device literacy in Senegal within the context of the AppliCafé project. Research in this area has been mostly conducted in Anglophone countries. We designed a kiosk structure that we call AppliCafé (derived from the term cyber café) that can move between locations and is equipped with mobile technology, including training videos and a mobile application. This project aims at teaching people on how to use their smartphones efficiently. We used a qualitative approach based on surveys and interviews to gather data from users on their mobile phone usage and their opinions on the structure, mobile app and videos. We also interviewed local developers and entrepreneurs to get their perspective on mobile app adoption, usage, and the issues they meet in promoting their apps and scaling their businesses. We outline interesting mobile device usage patterns including the use of web sites rather than mobile apps to save data. We demonstrate the importance of a physical learning environment for users to improve their mobile device literacy skills and for developers to engage with users to produce better quality and fitted apps.
本文介绍了在塞内加尔的移动设备读写能力的研究在应用程序技术项目的背景下。这方面的研究大多是在英语国家进行的。我们设计了一个亭子结构,我们称之为“应用咖啡馆”(源自“网络咖啡馆”一词),它可以在不同地点之间移动,并配备了移动技术,包括培训视频和移动应用程序。这个项目旨在教人们如何有效地使用智能手机。我们采用基于调查和访谈的定性方法收集用户的手机使用情况以及他们对结构,移动应用和视频的意见。我们还采访了当地的开发者和企业家,了解他们对手机应用的采用和使用情况的看法,以及他们在推广应用和扩展业务时遇到的问题。我们概述了有趣的移动设备使用模式,包括使用网站而不是移动应用程序来保存数据。我们展示了物理学习环境对用户提高移动设备读写能力的重要性,以及开发人员与用户互动以生产更高质量和适合的应用程序的重要性。

Over 95% of the population in Uganda relies on solid fuels for their cooking and heating needs [1]. These are burned in a variety of cooking appliances, ranging from three stone fires to improved cookstoves (ICS). Appropriate Energy Saving Technologies (AEST Ltd.) is a social business that manufactures and distributes Makaa fuel briquettes and charcoal cookstoves in Soroti, Uganda. This work summarizes collaboration with AEST to design for improved performance, usability, and manufacturability of their Makaa cookstove product. Two prototypes were selected and laboratory performance tested. The prototypes included engineered insulation materials which were compared to the current Makaa stove with mineral insulation. Techno-economic analyses were also performed in order to estimate and compare the production cost for each stove model. Combining the performance results with the cost analyses indicates that the most cost-effective design is a combination of the metal grate and vermiculite models. This design maximized performance and usability while also minimizing the time and cost of production. Recommendations were made for further product development, and an open-access cost-analysis tool was made available online to carry out similar techno-economic analysis.
乌干达95%以上的人口依靠固体燃料来做饭和取暖。它们在各种烹饪器具中燃烧,从三石火到改进的炉灶(ICS)。适当节能技术(AEST有限公司)是一家社会企业,生产和分销Makaa燃料压块和木炭炉灶,位于乌干达索罗蒂。本工作总结了与AEST的协作,以设计改进其Makaa炉灶产品的性能、可用性和可制造性。选择了两个原型并进行了实验室性能测试。原型包括工程绝缘材料,与目前的Makaa炉进行了矿物绝缘比较。还进行了技术经济分析,以估计和比较每种炉子模型的生产成本。结合性能结果和成本分析表明,最具成本效益的设计是金属格栅和蛭石模型的组合。这种设计最大限度地提高了性能和可用性,同时也最大限度地减少了生产时间和成本。提出了进一步开发产品的建议,并在网上提供了一个开放获取的成本分析工具,以进行类似的技术经济分析。

Timely and robust diagnosis of plant diseases and nutrient deficiencies play a major role in management of crop yield. Automation is a low cost alternative to human experts and can help to detect early onset of crop diseases which aids faster decision making and in giving recommendations to farmers to curb yield loss. We have developed a smart-phone based participatory sensing application for agriculture which is used by farmers to scout their fields for events of interest, especially those related to crop health. Recently, deep convolutional neural networks (CNN) have emerged as a prominent technique in computer vision related challenges and such deep-learning based models could prove as an important tool to do just-in-time assessment of crop health. With a view to building state-of-the-art diagnostic capabilities on the phone, we present analysis of CNN models in terms of accuracy, memory, and inference time. Effects of change in hyperparameters have been evaluated in terms of accuracy. The trained model gives 99.7% classification accuracy with satisfactory inference time and model size which assures the application of CNN architectures for real-time crop state diagnosis on a large scale with limited hardware capabilities.
及时有力地诊断植物病害和营养缺乏在作物产量管理中起着重要作用。自动化是人类专家的低成本替代品,可以帮助发现作物疾病的早期发作,这有助于更快地做出决策,并向农民提供建议,以遏制产量损失。我们开发了一种基于智能手机的农业参与式传感应用程序,农民可以用它来侦察他们的田地,寻找感兴趣的事件,特别是那些与作物健康有关的事件。最近,深度卷积神经网络(CNN)已经成为计算机视觉相关挑战中的一项突出技术,这种基于深度学习的模型可以被证明是实时评估作物健康的重要工具。为了在手机上建立最先进的诊断功能,我们在准确性,记忆和推理时间方面对CNN模型进行了分析。超参数变化的影响已经根据准确性进行了评估。训练后的模型具有99.7%的分类准确率和令人满意的推理时间和模型大小,这保证了CNN架构在硬件能力有限的情况下大规模实时作物状态诊断的应用。

Agriculture is the backbone of African economies, especially in rural areas where over 70% of people rely on subsistence farming for their livelihood. In Rwanda and Uganda, where Africa Development Promise (ADP) works, 90% of economically active women work in the agricultural sector. Overall women work more and longer hours compared to men because of additional household responsibilities such as preparing food, collecting fuelwood and water. This time deficit leaves no time for education or productive endeavors. The paper argues that access to new technologies that save time, especially tedious and laborious work, can have a significant positive impact on women's efficiency, productivity and income-generating potential. It shares ADP's shift from a single-entry economic development approach to a holistic approach that incorporates access to solar energy to support women's economic endeavors. The paper is shared with organizations addressing similar challenges, but more importantly to seek feedback from development practitioners.
农业是非洲经济的支柱,特别是在农村地区,70%以上的人口依靠自给农业为生。在非洲发展承诺(ADP)开展工作的卢旺达和乌干达,90%从事经济活动的妇女在农业部门工作。总的来说,由于妇女要承担额外的家庭责任,如准备食物、收集柴火和水,因此妇女的工作时间比男子更长。由于时间不足,没有时间进行教育或生产活动。该报告认为,获得节省时间的新技术,特别是繁琐和费力的工作,可以对妇女的效率、生产力和创收潜力产生重大的积极影响。它与ADP一样,从单一的经济发展方式转变为综合利用太阳能的方式,以支持妇女的经济努力。该论文与处理类似挑战的组织共享,但更重要的是寻求来自开发实践者的反馈。

Pseudo fatigue test of passive energy-returning prosthetic foot 被动回能假足假疲劳试验

Improving in the quality of life by expanding functionality and durability while continually reducing the fabrication costs and maintaining the possibility of local fabrication, these are the four key design requirements for lower-limb prosthetics with humanitarian applications. Currently, however, there are few foot prostheses that meet these requirements. The solutions available world-wide include passive-static solid-ankle cushion-heel (SACH), passive-dynamic, and active prostheses. Perhaps the best solution available is the injection-molded one-size-fits-all Niagara foot but it is both unstable for heavier patients and not suitable to interface with patient footware, thereby limiting its acceptance in footware conscious cultures. This research focuses on demonstrating the functionality and durability of the Tec-LIMBS fiber reinforced polymer (FRP) prosthetic foot designed with the aforementioned four-fold objective. We hypothesize that a low-cost FRP passive-dynamic prosthetic foot can be manufactured locally while still meeting durability, energy-return requirements and being socially aesthetic. The prosthesis is validated first, for energy-return via static tests as compared to two other commercial products, and second, for durability through a 500,000 gait-cycle fatigue test based on the ISO 22675 standard. Both tests are conducted employing a universal testing machine. The work reported herein is a continuation of prior prototyping that compared the prostheses via roll-over shape. The designed prosthesis has a comparatively higher energy-return characteristic for both keel and heel — above the two common competitors — and has successfully passed the fatigue test without deformation. The reported testing further demonstrates that the prosthesis design is ready for in-field patient testing and manufacture.
通过扩展功能和耐用性来提高生活质量,同时不断降低制造成本并保持本地制造的可能性,这是具有人道主义应用的下肢假肢的四个关键设计要求。然而,目前满足这些要求的足假体很少。世界范围内可用的解决方案包括被动-静态固体踝关节缓冲跟(SACH),被动-动态和主动假肢。也许最好的解决方案是注射成型的一刀切的尼亚加拉足,但它既不适合较重的患者,也不适合与患者的鞋类接触,因此限制了它在鞋类意识文化中的接受度。这项研究的重点是展示Tec-LIMBS纤维增强聚合物(FRP)假肢脚的功能和耐久性,该假肢脚具有上述四重目标。我们假设一种低成本的FRP被动动态假肢足可以在当地制造,同时仍然满足耐久性、能量回报要求和社会审美。首先,与其他两种商业产品相比,该假肢通过静态测试验证了能量返回,其次,通过基于ISO 22675标准的500000次步态循环疲劳测试验证了耐久性。两项试验均采用通用试验机进行。本文报道的工作是先前原型的延续,通过翻转形状比较假体。所设计的假体龙骨和足跟都具有较高的能量回传特性,超过了两种常见的竞争对手,并成功地通过了无变形的疲劳试验。报告的测试进一步表明,该假体设计已经准备好进行现场患者测试和制造。

Towards energy conservation in campus using Wireless Sensor Network 利用无线传感器网络实现校园节能
Pub Date : 2017-10-01 DOI: 10.1109/GHTC.2017.8239336

Educational institutions, should set a role model, in the reduction of the carbon foot print, to protect mother earth. In this paper we focus on designing a Wireless Sensor Network (WSN) based system, which can efficiently conserve the energy of class rooms and labs. We have identified temperature, light, pressure sensors to be utilized for this application. Infra Red receiver and transmitter is used to detect an event whether a person is leaving the room or not. Server room is checked for humidity, temperature, smoke by an integrated sensor, which sends the sensed data to the cloud. So all the sensors send the data periodically to the cloud, which processes the collected data and send the triggered response to the necessary output device and message the facility manager to take administrative actions. The status of each room in each floor is ultimately received at the central monitoring station at the ground floor of the building. The proposed system is designed in such a manner, it can be replicated cost-efficiently in multiple buildings within a campus by using low cost sensors and with the existing communication devices. Therefore this Green Campus System (GCS) design based on wireless sensor networks help in meeting the target of sustainable cities by reducing the overall energy consumption and improving the efficiency in the energy resource management.
教育机构,应该树立榜样,在减少碳足迹,保护地球母亲。本文重点设计了一种基于无线传感器网络(WSN)的系统,可以有效地节约教室和实验室的能源。我们已经确定了用于此应用的温度,光,压力传感器。红外线接收器和发射器用于检测一个事件,无论一个人是否离开房间。服务器室通过集成传感器检测湿度、温度和烟雾,并将检测到的数据发送到云端。因此,所有传感器定期将数据发送到云,云处理收集到的数据,并将触发的响应发送到必要的输出设备,并向设施管理人员发送消息,以采取管理操作。每层每个房间的状态最终由位于建筑物底层的中央监测站接收。所提出的系统是这样设计的,通过使用低成本的传感器和现有的通信设备,它可以经济高效地在校园内的多个建筑物中复制。因此,基于无线传感器网络的绿色校园系统(GCS)设计通过降低整体能耗和提高能源管理效率,有助于实现城市可持续发展的目标。

In this paper we focus on designing a Wireless Sensor Network (WSN) based system, which can efficiently conserve the energy of class rooms and labs. We have identified temperature, light, pressure sensors to be utilized for this application. Infra Red receiver and transmitter is used to detect an event whether a person is leaving the room or not. Server room is checked for humidity, temperature, smoke by an integrated sensor, which sends the sensed data to the cloud. So all the sensors send the data periodically to the cloud, which processes the collected data and send the triggered response to the necessary output device and message the facility manager to take administrative actions. The status of each room in each floor is ultimately received at the central monitoring station at the ground floor of the building.

Response time of the emergency services is vital in drastically improving the chances of survival and of meaningful recovery for the affected individuals in emergency situations. Often precious time is often lost for emergency services due to traffic, especially at traffic intersections. What we propose is a dynamic solution to the aforementioned problem using an intelligent network of smart traffic lights which all turn green in anticipation of an approaching emergency vehicle, thus providing unhindered passage to it. Further, so to facilitate the implementation of the aforementioned logic in non-smart traffic networks, a wireless embedded system based hardware solution is proposed to convert existing autonomous traffic light systems into a networked one.
紧急服务的反应时间对于大幅度提高紧急情况下受影响个人的生存和有意义康复的机会至关重要。由于交通堵塞,特别是在十字路口,急救服务往往会浪费宝贵的时间。我们提出的是一种动态解决上述问题的方法,使用智能交通灯的智能网络,当紧急车辆驶近时,这些智能交通灯都会变绿,从而为紧急车辆提供畅通无阻的通道。此外,为了便于上述逻辑在非智能交通网络中的实现,提出了一种基于无线嵌入式系统的硬件解决方案,将现有的自主交通信号灯系统转换为网络化交通信号灯系统。

Four 5.8 GHz band transceivers at the University of Colorado at Boulder (UCB) were first operated as a wide area local area network (WLAN) in April of 2017. The purpose of this WLAN is to serve as a testbed for installations to be made in the developing world as a part of the IEEE Smart Village program. The configuration of the components is discussed in detail. The testbed is self-powered by solar micro-grids that are present at each node. Evidently, the micro-grids are designed for fail-safe 24/7 operation. Test data is presented on the operation of the network when used to provide information on demand from a central server to any of the remote stations. The network provides continuous data on the operation of the micro-grids including their innovative energy storage systems (ESSs) that are based on lithium ferro-phosphate battery technology. This test data resembles that of a smart system monitoring multiple islanded micro-grids. Plans for expanding the testbed to include a mobile station as well as longer distance arms are also presented. A primary purpose of the testbed is to determine the suitability of components, power levels and protocols for application of wireless LANs (WLANS) in remote areas. Discussion of what the testbed test results say about component applicability conclude the paper.
2017年4月,科罗拉多大学博尔德分校(UCB)的四个5.8 GHz频段收发器首次作为广域局域网(WLAN)运行。该WLAN的目的是作为一个测试平台,作为IEEE智能村计划的一部分,在发展中国家进行安装。详细讨论了组件的配置。试验台由每个节点上的太阳能微电网自行供电。显然,微电网是为24/7无故障运行而设计的。当用于从中央服务器向任何远程站点提供所需的信息时,测试数据是关于网络运行的。该网络提供了关于微电网运行的连续数据,包括基于磷酸铁锂电池技术的创新储能系统(ess)。该测试数据类似于监测多个孤岛微电网的智能系统。还提出了扩大试验台的计划,包括一个移动站以及更远距离的武器。该试验台的主要目的是确定在偏远地区应用无线局域网(wlan)的组件、功率水平和协议的适用性。最后讨论了试验台测试结果对构件适用性的影响。
