Our goals were to increase children's exposure to STEAM topics, spread awareness of STEM fields, and build confidence and interest in STEM fields with underrepresented students in a fourth and fifth grade afterschool program so that these students could see themselves in STEM roles in the future. Our program involved kinesthetic movement, collaboration, and project-based learning. The program encouraged self-expression through the lens of play, creativity, and movement. Students engaged in coding through technology-enabled activities. This kind of educational enrichment begins by scaffolding interdisciplinary collaborations and promoting a culture where engineering, science, and art are equally considered. The overall framework of our program addressed many UN Sustainable Development Goals including quality education, gender equality, and reduced inequalities, ultimately contributing to the development of sustainable cities and communities. This project was conducted by university students working in a research group with a faculty member at the University of Washington. Our outreach program succeeded in reaching underrepresented students, with female students and all students without previous STEM experience showing the most substantial gains in confidence and interest over the course of the program.","PeriodicalId":314837,"journal":{"name":"2020 IEEE Global Humanitarian Technology Conference (GHTC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122160141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a real-time camera-based indoor navigation application for the blind and visually impaired in known environments. Contrary to other systems for similar purposes, our system executes all computation locally on mobile devices and does not need any infrastructure-based sensor and signal support. The use of the system is divided into two stages: an offline stage, in which a sighted person helps with landmark identification and route planning, and an online stage, in which a visually impaired person can navigate with voice prompts from the app. Predefined landmark images and navigation information are stored in a database in the offline stage. Navigation information consists of the landmark position, the turning angle, the turning direction, and the distance to the next landmark. In the online stage, navigation information is retrieved from the current landmark image by successfully matching video frames in real time. A similarity score is calculated by ORB using Hamming distances. Voice feedback is provided for users with a text-to-speech function. Our system minimizes the error caused by users’ manipulation and improves stability and accuracy by updating similarity scores continuously.","PeriodicalId":314837,"journal":{"name":"2020 IEEE Global Humanitarian Technology Conference (GHTC)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126624183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our system will be mounted to a vehicle and record the depth of objects in the camera’s view while the vehicle is in motion. The GPS coordinates of objects are computed based on estimated depth, vehicle coordinates, and orientation, available from included sensors. We tested our prototype on objects at various distances from the system and achieved feasible accuracy with acceptable error in the estimated depth. In the future, we hope to deploy the system in parts of sub-Saharan Africa, to detect and geolocate irrigated agricultural plots during the dry season. Then we plan to use that collected data to inform and train machine learning models that use remote sensing and satellite imagery.","PeriodicalId":314837,"journal":{"name":"2020 IEEE Global Humanitarian Technology Conference (GHTC)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123748127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While much work has been done to understand the many factors driving successful interventions, little research has been done to quantify and then model the adoption of these technologies. Current optimization models to maximize impact rely on the effective prediction of adoption, yet this piece remains the least understood component. The purpose of this paper is to outline the various ways in which being able to model the adoption of household clean energy technologies would be beneficial for designers, implementation organizations, and policymakers to aid in their design and decision-making processes. We provide a brief review of the literature and current challenges to adoption, examples of current methods and modeling tools that can be used to optimize sustainable impacts, and how these tools could be improved through adoption modeling. We discuss the benefits of being able to model adoption for various stakeholders in the clean energy sector along with proposing some methodologies that can be used to accomplish this goal.","PeriodicalId":314837,"journal":{"name":"2020 IEEE Global Humanitarian Technology Conference (GHTC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128152095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the United Arab Emirates (UAE), undergraduate students are diverse not only in their nationalities but also in the high school curriculum they have followed. This paper describes a pilot study conducted at Rochester Institute of Technology (RIT), Dubai on identifying the influence different high school curricula have on student performance in universities. Academic and non-cognitive measures of 213 undergraduate student records were studied. Performance patterns of students based on their high school curricula were studied. Indian curriculum students were found to fare better in university than other students. American curriculum in UAE was found to be a modified version of UAE’s national curriculum, MOE. College readiness of these students was found to be the lowest in the population studied. American curriculum students displayed a prominent gap between the self-perception of their abilities and the reality of their performance, Grade Point Average. Scaling this study with more records will enable results and insights to be applicable to a wider population. Educators and accreditation authorities can use these insights to provide customized support to improve the college readiness and future success of students.","PeriodicalId":314837,"journal":{"name":"2020 IEEE Global Humanitarian Technology Conference (GHTC)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121138146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we demonstrate a series of techniques for assessing the damage and the recovery process from the humanitarian crisis in Sana’a, Yemen. In particular, we make use of the Visible Infrared Imaging Radiometer (VIIRS) Day/Night Band (DNB), which produces nightly data on illumination levels globally at 750m resolution. While nearly all work that has previously been performed using the VIIRS DNB dataset uses monthly or annual composite data, we develop novel methods that leverage the nightly availability of this data source, particularly for mapping the scale and extents of illumination changes, accurately identifying the day when bombing occurred and illumination conditions changed, characterizing electricity outage patterns, and tracing the recovery of nighttime lighting both spatially and temporally. For each of these methods, we compare with publicly-available datasets to verify the accuracy of our observations. In total, these data, available only 1 day after an event, and the resulting analyses can be especially valuable for disaster response as well as targeting and tracking investments in recovery.","PeriodicalId":314837,"journal":{"name":"2020 IEEE Global Humanitarian Technology Conference (GHTC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128699845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnetic resonance imaging (MRI) would be the preferred diagnostic method for infant hydrocephaleus.

A low-cost MRI technology is under development by reducing the strength of the magnetic field and the use of alternative technologies to create the magnetic field. This paper describes the embodiment design process to match this new MRI technology under development with the specific characteristics of the healthcare system in Uganda.A context exploration was performed to identify factors that may affect the design and implementation of the low-field MRI in Ugandan hospitals and Ugandan healthcare environment. The key-insights from the technology- and context-exploration were translated into requirements which were the starting point for the design process.

To this end, spectrum measurements were conducted at different locations in the country to establish a measure of utilization or occupancy of the UHF TV spectrum, specifically in the 600 MHz band. Our results show significant white space in the UHF TV band in rural areas, which opens the possibility for the reallocation or re-purposing of this spectrum for mobile networks to provide Internet connectivity in said regions. The 3rd Generation Partnership Project (3GPP), in particular, supports operation of the 4G wireless communications standard, Long Term Evolution or LTE, in the 600 MHz band through Band 71 (617-698 MHz), which is currently not adopted in the Philippines. With policy reform in mind, we have developed an LTE base station prototype, LokaLTE, that supports the case for opening Band 71 specifically for use by CCNs to offer connectivity in rural areas. To our knowledge, LokaLTE is the first LTE base station implementation using OpenCellular and srsLTE operating at Band 71. The low utilization of the 600 MHz band in rural areas and the accessibility of cost-effective infrastructure through LokaLTE are therefore intended to provide the national regulatory and planning agencies in the Philippines with evidence that underpins a policy of regionally selective allocation of Band 71 for use by CCNs to offer LTE service in underserved and unserved regions, thus helping to bridge the long standing digital divide in the country.","PeriodicalId":314837,"journal":{"name":"2020 IEEE Global Humanitarian Technology Conference (GHTC)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122807773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
