Reducing pilot workload through a standardized landing procedure will help maximize safety during landing. The Federal Aviation Administration (FAA) provides many commercial aircraft with standardized procedures for landing, but the same level of support does not exist for light sport and experimental aircraft. In order to calculate a landing approach that can be customized to multiple light sport and experimental aircraft, a model has been developed to test various speed and power combinations with the given runway parameters to determine the best approach(es) for that given aircraft and runway. The simulation model is used to minimize the workload required by ensuring that only the engine power (revolution per minute-RPM) or the approach airspeed (miles per hour) variable remains constant throughout the landing sequence. Since the pilot needs to adjust the speed and power settings in order to follow the landing procedure, keeping one of these parameters constant will minimize pilot workload.","PeriodicalId":426864,"journal":{"name":"2016 IEEE Systems and Information Engineering Design Symposium (SIEDS)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114235799","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}

Currently, consulting firms strive to use data to support client's business decisions with evidence. To be effective at this, consultants must consider the applicability of both internal and external data libraries to their clients' requirements. Frequently, evaluating the applicability of data sets is a manual process, which can be costly to the firm and the client. This paper describes a technical approach to automate this process. Specifically, it details the structure of a software application, named UVa Open Miner, capable of assessing the applicability of data sources to client projects. This UVa Open Miner aims to maximize the scale and diversity of candidate data sets, increase the relevance of data found, and maintain manageable computational complexity. UVa Open Miner consists of two segments: mapping and matching. The mapping component text mines web pages to identify an ontology of keywords describing the business requirement. This enables users to handle diverse business requirements from various industry verticals. The matching component scores data sets based on a relevance factor obtained from the ontology map. To validate the application, subject matter experts provided business requirements for a problem in their domain, and validated the application's results. Professionals in environment science, political science and policy-making fields found the application to be useful. Therefore, the application, along with the framework used, can be refactored into a reusable solution for consulting firms to use for their clients.","PeriodicalId":426864,"journal":{"name":"2016 IEEE Systems and Information Engineering Design Symposium (SIEDS)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128780338","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}

Techniques such as topic models are shown to be useful in automatically extracting the topical or semantic content from unstructured data. Such a system should consume a large amount of text and extract meaningful patterns usually within a specified amount of time. Graphics Processing Unit is increasingly being used for computationally intensive tasks because of the inexpensive, high-performance raw processing power it has to offer. In this paper, we implement, test, and compare various topic modeling algorithms in a Graphics Processing Unit to achieve faster computing time compared to traditional implementations in a Central Processing Unit. The goal is to execute parallel Graphics Processing Unit versions of algorithms, such as Latent Dirichlet Allocation and Latent Semantic Analysis, and quantitatively assess the performance of each algorithm in comparison with serial or multi-core versions of the same topic modeling algorithms. The study aims to provide a comprehensive understanding of the effectiveness of a spectrum of Topic Model algorithms, the merits of such models in the Graphics Processing Unit, and the magnitude of efficiency improvement that can be achieved. Experimental results show that Topic Modeling algorithms can achieve 10x to 40x speedup in the GPU framework.","PeriodicalId":426864,"journal":{"name":"2016 IEEE Systems and Information Engineering Design Symposium (SIEDS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131033382","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 technology can be used in Heating, Ventilation and Air Conditioning (HVAC) systems to lower fan operating speeds, reducing energy consumption. The client has expressed a need for a more effective means of control for the operation of their two air handling units which regulate airflow throughout their office building located on a brewing facility campus. Currently, the supply fans for both air handlers (AHUs) operate at full capacity, regardless of occupancy of the building. The implementation of Variable Frequency Drives (VFDs) on these supply fans was explored due to the client's need for lower operating cost for the HVAC system serving the building studied by automating the Air Handler control. Using industry simulation and estimating software, a VFD schedule was developed to determine the capacity for operational cost savings for these two rooftop units, based on occupancy of the building. During weekends and non-business hours during the week, the power to the supply fans was modeled at lower percentages of the full operational capacity. The results of this analysis show that the implementation of VFDs on these two air handling units can reduce operational HVAC costs by 18%.","PeriodicalId":426864,"journal":{"name":"2016 IEEE Systems and Information Engineering Design Symposium (SIEDS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131827300","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}

Tearing it causes loss of mobility and need for surgery. There is a 13% chance for a National Collegiate Athletic Association athlete to tear their anterior cruciate ligament each year. The recovery process can take up to 9 months, about a quarter of a collegiate athlete's career and 44% of those who complete rehabilitation return to athletic participation. Seventy percent (70%) of anterior cruciate ligament injuries occur from non-contact mechanisms. These decompose into 5 types of failure mechanisms. An analysis was performed on flexion/extension (37%) failure mechanisms. Examinations of the equations of motion of the knee shows the ground reaction and muscle force have the highest contributing weight when compared to the four (4) main contributing factors. The proposed solution includes a biofeedback sleeve that stores inputs and converts it to a tibial shear force approximator. From there, the sleeve warns the athlete if they are approaching a dangerous tibial shear force level. The proposed plan for preventing anterior cruciate ligament will produce $593,400,000, with $483,341 startup costs.

Most of these studies are based on macroeconomic models that quantify the direct and indirect economic losses from a disruption. Direct economic losses occur due to damaged facilities or when consumers change their purchasing behavior because of the disruption. Indirect economic losses occur when directly impacted businesses consequently reduce their orders to their suppliers. Indirect economic losses are often larger than direct economic losses. This paper compiles the results from these economic models in order to compare the costs of different disruptions and help decision makers prioritize among disruptions. We compare the direct and indirect economic losses from a variety of disruptions, including earthquakes, hurricanes, terrorist attacks, pandemic diseases, and port closures. Some studies model hypothetical scenarios, but other studies quantify the economic losses from historical events such as the September 11 attacks and the 2011 Japanese tsunami. This paper provides a useful benchmark to understand the consequences from disruptions and highlight areas that public officials could address in planning for future disruptions.","PeriodicalId":426864,"journal":{"name":"2016 IEEE Systems and Information Engineering Design Symposium (SIEDS)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124626916","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}

With the rapid technological advancements of sensors, Wireless Sensor Networks (WSNs) has become the main technology for IoT. We investigated the security of WSNs in an environmental monitoring system with the goal to improve the overall security. We implemented a Secure Temperature Monitoring System (STMS), which served as our investigational environment. Our results revealed a security flaw found in the bootstrap loader (BSL) password used to protect firmware found in the MSP430 MCU. We demonstrated how the BSL password could be brute forced in a matter of days. Furthermore, to our knowledge we illustrated the first sample of how an attacker can reverse engineer firmware and obtain WSN cryptographic keys. Our sample provides a step-by-step procedure on how to reverse engineer MSP430 firmware. We contributed a solution to improve the BSL password and better protect firmware found in the MSP430 chips. The Secure-BSL software we contributed allows the randomization of the BSL password. Our solution guarantees brute force times in a matter of decades. The impractical brute force time assures the security of firmware and prevents future reverse engineering tactics. In addition, our Secure-BSL software supports two-factor authentication, therefore adding another layer of security. The two-factor authentication feature allows developers to specify a user-defined passphrase to further protect the MSP430 MCU. Our research serves as proof that any security implemented in a WSN environment is broken if an attacker has access to firmware found in sensor devices.","PeriodicalId":426864,"journal":{"name":"2016 IEEE Systems and Information Engineering Design Symposium (SIEDS)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126957736","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}

Alternative methods of commuting to work, such as biking, are becoming more popular in the Charlottesville area. To meet this growth, the Charlottesville Parks and Recreation department is developing several commuter paths. There are currently no lighting systems in place for the newly developed paths. While keeping the paths lit for specific hours seems reasonable, doing so not only uses excess energy, but prior research has also shown that lighting park areas when people are not present encourages criminal activity. A smart lighting system is better equipped to deal with irregular use and provide safety to its users. The objectives driving this project are enhancing the safety of commuter paths in parks while maintaining cost and energy effectiveness. The new lighting system will accomplish these objectives by lighting sections of the path after dark, only when that section is in use. The system uses PIR sensors on each light pole to detect path users and transmit information to an Arduino microcontroller mounted on that pole, which turns on specific lights using a relay. When the PIR sensor detects a user, the light at that pole and the lights in front and behind turn on. For the basic wired design of the system, all information is conducted using 22 AWG wires, while the preferred wireless design uses Xbee modules to transmit information between Arduinos. The final deliverable is a functional wireless prototype installed as a demonstration project in a Charlottesville Park.","PeriodicalId":426864,"journal":{"name":"2016 IEEE Systems and Information Engineering Design Symposium (SIEDS)","volume":"583 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123042520","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}
