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.

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.

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.

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.

Telemedicine systems are becoming prevalent in today's healthcare scenarios, especially in India where a large portion of the population resides in remote and rural regions where availability of specialty healthcare is scant. Many such telemedicine system implementations can be found in the existing literature. Since critical data are being transmitted over these networks, the reliability of these systems is highly important. This paper discusses about the quality of service (QoS) requirements for achieving reliability for such systems. The paper discusses the importance and acceptance of such rescue vehicles which are equipped with the telemedicine facilities. This involves the role of paramedic assistance, multiple access technologies along with acquisition and remission of vital parameters such as electrocardiogram (ECG), blood pressure (BP), pulse rate (PR) etc. to a specialist doctor at the remote hospital. A comprehensive survey has been done among the various stakeholders of the proposed system. The paper focuses on the need for the QoS mechanisms in the proposed telemedicine system for the rural rescue and health care emergencies.

Development, adoption and use of humanitarian technologies are influenced by a country's innovation ecosystem. In the Information and Communication Technologies (ICT) domain, tech or innovation hubs are critical to promoting entrepreneurship and fostering startups. In analyses of these hubs, success is often measured by the number of high growth startups created. However, while useful in the context of Silicon Valley, we argue that for developing countries such measures are misguided and lack nuance. We provide an alternative set of eight categories of success measures, developed through a case study of ICT entrepreneurship in Rwanda. The eight success categories reflect alternative definitions of success, capturing the value hubs create beyond launching high-growth startups and were gathered from groups of stakeholders including entrepreneurs, mentors, tech hub staff, and government officials. Understanding differences between these groups' views will enable better service delivery by tech hubs and more realistic expectations of their role in promoting innovation. Exploring these different dimensions of success and value also provides insights into how innovation ecosystems and tech hubs in developing countries can be better supported. This research is relevant to development professionals, researchers, and government officials with an interest in promoting innovation and entrepreneurship.

Coastal communities constitute ∼40% of the total U.S. population, and roughly 50% of the national GDP is attributed to socio-economic activities in these regions. Port system operations and related industries constitute a majority of the industrial activities occurring in the region. This paper presents preliminary results from our work on the development of “FREIDA in Ports”: an interactive information resource and modeling framework for port communities, that may be used to enhance resilience to extreme weather events and enable sustainable development. Because of the complex nature of port activities and its interconnections with the social, political, economic and environmental aspects of the coastal communities, it is often very difficult to map out a comprehensive humanitarian adaptation plan for sustainable port and industrial operations in the region. The framework of information resources includes a broad range of agents and related data/modeling resources that could play a key role in building port communities resilient to natural disasters and environmental impacts of industrial operations in the region. A subsequent section explores possible policy recommendations, disaster management and pollution mitigation techniques that could be designed based on data organized via the information framework. The illustrative scenario analysis discusses the impacts of catastrophic weather events on the U.S. energy sector using U.S. EPA's MARKAL model. Resulting impacts on energy generation mix, air emissions, and energy prices are presented in detail, in addition to a detailed outline of the modeling technique, and a summary of the overall results.

Worldwide, more than one billion people lack access to electricity. Village electrification using microgrids has the potential to provide rural households with reliable electricity that not only delivers light but also creates opportunities to use electricity for productive uses that enable economic development. Using a stochastic simulation model, we demonstrate that costs can be reduced by designing for less than 100% reliability, but the cost tradeoff is significantly impacted by the capital investment in distribution systems. Models also illustrate how active encouragement of productive use can transition microgrids from demonstration projects to ‘bankable’ investments. Modeling indicates that load growth of 9% annually for 8 years — an achievable goal with proper information and access to capital — lowers the cost of electricity supply by greater than 25%. Growth models also illustrate that higher total growth should be coupled with diversification of both generation and loads. Our results have several important policy implications. First, rural electrification can be cost effectively achieved if integrated with rural development, and conversely, electrification without sufficient attention to development is unlikely to produce economically sustainable systems. Second, regulators should consider standards requiring that private providers of electricity have effective processes for both cost minimization & encouragement of local development.

Lithium-ion batteries are currently the most widely used form of energy storage in electric vehicles. They have a high vitality thickness with a potential for higher limits, they don't need prolonged priming when they're new. However, they're subject to aging rapidly even when they aren't being used. Being able to predict the life expectancy of these batteries can prove to be beneficial in order to see the limitations of using them in vehicles. However, continuous use of these batteries eventually leads to a shorter and shorter battery life. The goal of this work is to implement ANN (Artificial Neural Network) Prediction Model to connect between various characteristics of this battery type. ANN-Predictive model is implemented, trained, and tested based on empirical samples, improved Thevenin model, and MATLAB codes. This neural model can anticipate values in — between learning values, likewise make introduction between expectations to learn and adapt information at different qualities. Arithmetical nonlinear capacities which, interfaces amongst information sources and yields for neural systems with its related Simulink model are concluded. This is done keeping in mind the end goal to help any scientist without the need of preparing the neural system each time. This model' sources of information are: the Time and SOC (State-of-Charging). Its yields are: Average Degradation Function (ADF), Degradation Density Function (DDF), Cycle Life L(x), Depth of Discharge (DoD) and Capacity rate. It contains two layers, one covered up with log-sig capacity and 10 neurons; and second layer has pure-line work with 5 neurons. The electric vehicle technology and its associated storage devices can help the humanitarian to go beyond cutting edge technology and help small villages. One day, the electric vehicles will be the next cell phone where everyone will have one. Final presentation includes characteristics, regression, comparisons and Lithium-ion battery ANN curves.

Malawi Children's Village (MCV) operates a secondary school of approximately 560 students in Mangochi, Malawi, and its strategic goal is to add computer studies into its curriculum. The first step to achieving this goal is for MCV to establish and sustain a teachers-only computer lab. This case study examines the process by which a team of volunteers identified this as the first step, the team's recommendations for sustaining the lab long-term, and the socio-economic context in and infrastructure constraints around which MCV will build and operate its lab.
