This method is inefficient when data are only required for the first hundred feet above the ground. Free-flying balloons and the attached payload drift away from the launching location and are often not recovered. Tethered balloons require large amounts of helium and become unstable with increased winds, and inflating balloons takes an extended period of time and requires a skilled team. The scope of this project is to eliminate the impracticalities of balloon-based measurement systems by creating a recoverable, versatile, user-friendly unmanned aerial vehicle (UAV). The project requires development of a flight-control system, a data-collection system, and a communications and user interface. The development of the flight-control system involved researching autonomous flight controllers, followed by the construction, prototyping, and tuning of a hexacopter. Creating the data collection system required researching environmental sensors and determining the effects of the copter motion on sensor performance. The designed communications interface incorporated realtime data flow and local storage on the copter. The final product will be an autonomously flying hexacopter which can collect accurate weather-related data within the lowest 1000 feet of the atmosphere.","PeriodicalId":441073,"journal":{"name":"2014 Systems and Information Engineering Design Symposium (SIEDS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125390773","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}

Executive Order 13514, Federal Leadership in Environmental, Energy and Economic Performance, sets sustainability goals for federal agencies to reduce dependency on fossil fuels and decrease greenhouse gas emissions. The Federal Aviation Administration has over 4,300 registered vehicles in its motor fleet, and must reduce its emissions by 12.3% by 2020. This system provides an analysis of the life cycle costs and emissions reduction of the motor vehicle fleet at the William J. Hughes Technical Center. The analysis includes alternatives of low speed electric vehicles, neighborhood electric vehicles, and compressed natural gas vehicles. Three models are used to do analysis: (1) the demand model is a discrete-event simulation, used to determine the inventory needed to meet demand. Examples of demand events are mail delivery, and material shipping. The demand model's input is a vehicle inventory, and its outputs are metrics measuring the inventory's ability to meet demand. (2) A life cycle cost model composed of a deterministic and stochastic portions. The deterministic portion calculates preventive maintenance, overhead, and acquisition costs. The stochastic piece is a Monte Carlo simulation that projects energy consumption costs, corrective maintenance costs, and CO2 emissions through 2020. (3) A utility analysis to compare alternatives. Preliminary results indicate that the status quo inventory will not meet the requirements for GHG emission reduction. However, by reducing inventory and introducing electric vehicles, the requirements can be met while staying within current operating budgets. Based on the preliminary results, it is recommended that the FAA gradually introduce electric vehicles on an annual basis into their inventory to meet their sustainment goals by 2020.","PeriodicalId":441073,"journal":{"name":"2014 Systems and Information Engineering Design Symposium (SIEDS)","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122053005","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}

Without the use of a high magnification lens, the photographer must approach the wildlife, potentially creating an unsafe situation. Additionally, close proximity to wildlife can compromise an authentic, natural photograph. The goal of this project is to enable photographers to obtain close-up, high-quality photographs of wildlife while maintaining the safety of the photographer and the equipment as well as eliminating the need for expensive high powered lenses. The final prototype is a remote controlled robotic vehicle intended to move a digital single-lens reflex (DSLR) camera closer to an intended subject using a standard 50 mm lens. The robot is designed to navigate dry terrain typical of the Shenandoah area, including dirt, grass, loose gravel, and pavement, and traverse slopes of ±15°. An additional camera relays video feedback to a wireless device, allowing the user to drive the vehicle and position the DSLR camera from up to fifty feet away. A custom made elevation system on the robot enables the user to raise the camera to a height of 2.5 feet off of the ground. The robot has a runtime of over two hours and is rechargeable. The ultimate purpose of this robot is to provide close-up photographs at a lower cost than that of high magnification lenses. Viewing wildlife from short distances using a remote-controlled robot will also increase photographer safety and minimize adverse effects of human intrusion into animals' territory.","PeriodicalId":441073,"journal":{"name":"2014 Systems and Information Engineering Design Symposium (SIEDS)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124269653","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}

As important as it is to design new prosthetic heart valves, just as important is the need for appropriate performance metrics to evaluate prosthetic heart valves. This paper is focused on addressing this concern by proposing a novel metric of prosthetic heart valve performance and showing evidence that supports this claim. More specifically, existing flow performance metrics for prosthetic heart valves currently used by the Food and Drug Administration are based on basic flow characteristics which do not take into account the flow novelties exhibited by varying prosthetic heart valve designs. A more sophisticated flow performance metric, based on characterizing vortex ring formation in the heart and past prosthetic heart valves, is investigated herein to gain insight into the usefulness of the Vortex Ring Formation Number. Vortex Ring Formation Number is derived from understanding vortex ring formation, which is an important mechanism for fluid transport during ventricular filling. To the best of our knowledge, this is the first study to investigate Vortex Ring Formation Number across a variety of cardiac operating conditions. Our in-vitro results show that vortex ring formation can differentiate the performance of prosthetic heart valve designs. The implications are: improving prosthetic heart valve performance metrics, enabling surgeons to guide patients in selecting the most appropriate prosthetic heart valve to implant, and aiding engineers/scientists who continuously seek to improve prosthetic heart valve designs.","PeriodicalId":441073,"journal":{"name":"2014 Systems and Information Engineering Design Symposium (SIEDS)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123054288","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 suggests a rising concern about the influence of these sites on adolescent drinking behavior. Parents, health organizations, and school administrators need a deeper understanding of online promotional patterns in order to combat risky behaviors through intervention and education. To address these problems, we developed a system that automatically identifies alcohol promotions in online Twitter content. The identification of promotions was modeled using supervised machine learning algorithms. Predictor variables were derived from the content of tweets, the Twitter meta-data, and the network structure. We evaluated this system using held-out testing data in a cross-validated experimental design. We found that random forest models were best at predicting promotional tweets. Yet, logistic regression main effects models were useful in determining the significance of each variable, both Twitter specific and textual. For Twitter specific variables, number of hashtags and number of mentions significantly increased the likelihood of a tweet being a promotion. Using the TF-IDF method for textual predictors, we found that words that describe a type of alcohol, such as “beer” or “wine,” increased the likelihood of a tweet being a promotion. Our analysis provides information about the current state of online alcohol promotion, salient characteristics of promotions and promoters, and the influence of promotions on other users of social networking sites.","PeriodicalId":441073,"journal":{"name":"2014 Systems and Information Engineering Design Symposium (SIEDS)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124383103","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}

Unmanned aerial vehicles (UAVs) have become an increasingly useful tool due to their surveillance and reconnaissance capabilities. However, the use of many of these vehicles is limited to outdoor environments because of their size and reliance on Global Positioning Satellites (GPS). Knowledge of indoor environments is important so that the risk of entering an unsafe or unknown building can be minimized. This paper describes the development of a spatially aware, autonomous quadcopter that uses an Android control system and functions indoors. The system consists of a laser rangefinder for sensory input, a IOIO microcontroller for data communication across platforms, an autopilot system (APM) for flight control, and an Android phone for mission control. The Android Control and Sensor System (ACSS) is currently being developed by the Department of Defense (DOD), MITRE, and academic partners, and will be integrated into the solution. To be considered autonomous, the quadcopter must be able to make a map from the data provided by the laser rangefinder, determine its own location and position in that map, and then execute a set of navigational commands from the Android control system. The success of this project is measured by the system's ability to travel autonomously while simultaneously creating a map and being aware of its location.","PeriodicalId":441073,"journal":{"name":"2014 Systems and Information Engineering Design Symposium (SIEDS)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114802599","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}

Matatus are part of the paratransit (i.e. not fully public transit, and often utilizes smaller vehicles that are privately owned) system in Nairobi, providing service to millions of people. Despite their prominence, there is a lack of data both in terms of the number of Matatus as well as route frequency. For example, though some sources cite 15,000 Matatus in operation, there is significant variation in the estimates of the number of Matatu minibuses. The purpose of this project is to develop a low cost tracking system built with open source technology that can relay real-time location information to a database accessible by the Nairobi city planners. From this database, city planners will be able to analyze frequency and intensity of routes, and use this information to inform comprehensive plans. This paper covers the preliminary design and results for the four subsystems of the tracking system: power supply, microcontroller-sensor assembly, housing, and data processing. The open source Arduino based microcontroller assembly collects GPS data and saves it to an SD card. The data will then be sent via GSM technology to reach the cloud database. From there, the data can be exported and analyzed by the city planners using custom dashboards. The microcontroller will be powered by a battery array that is recharged by photovoltaic panels. The system will be designed so that additional sensor collection capabilities (e.g. air quality sensors) can be added to the device in the future.","PeriodicalId":441073,"journal":{"name":"2014 Systems and Information Engineering Design Symposium (SIEDS)","volume":"408 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116691112","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}

Following major storms in which the river flow rate exceeds 300,000 cubic feet per second (cfs), nutrients and sediment stored in the Lower Susquehanna Reservoir are deposited into the Chesapeake Bay. These excess nutrients facilitate algae blooms that hinder the growth of sub-aquatic vegetation (SAV) and harm the Bay's aquatic species. The Conowingo Dam, on the Lower Susquehanna River, is estimated to be at 85% of its sediment capacity. To reduce the sediment backlog, three dam sediment management alternatives have been identified: (i) No Mitigation, (ii) removal of sediment by Hydraulic Dredging and (iii) removal of sediment by Hydraulic Dredging and increasing the bottom shear velocity to avoid sediment build-up. A utility analysis conducted using a fluid mechanics, ecological impact and business model indicates annual removal of sediment at 5,000,000 cubic yards to produce slag product, with the instantiation of a flow diverter to increase bottom shear stress to be the best alternative.","PeriodicalId":441073,"journal":{"name":"2014 Systems and Information Engineering Design Symposium (SIEDS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123175782","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}

These two conflicting pressures come to a head with the University Admissions Department, which must meet target enrollment rates within their budget. The admissions department at George Mason University must currently hire outside application readers in order for admissions counselors to complete all fundamental admissions tasks by their deadlines. The hours worked by outside readers accounts for approximately 8% of hours worked by the freshman admissions staff during the reading season. One way of reducing labor costs is by reducing or reorganizing the staff to be comprised of fewer high salary employees. Lower wage employees are less skilled and are limited to performing specific tasks. The goal of this paper is to design the process and analyze the feasibility of reorganizing the admissions staff. To lower system costs and make the process feasible, reorganization must occur without decreasing enrollment rates or increasing the time students wait for service. The design alternatives tested were: (1) the current process, (2) Decreasing the number of counselors and increasing the number of outside readers, (3) Removing outside readers, adding fellows, and specializing tasks between fellows and counselors. and (4) Keeping outside readers and specializing tasks between fellows and counselors. The utility of each alternative from first to last are: 0, 0.290, 2, and 0.376.
