Therefore, early diagnosis and treatment are crucial for patient survival. Currently, Charlottesville ambulances that service the University of Virginia hospital are equipped with proprietary systems that send electrocardiogram (ECG) images while the ambulance is en route to the hospital. From an ECG, a doctor can diagnose a STEMI prior to patient arrival and prepare for surgery, thereby reducing the time delay. However, these ambulance systems are costly and provide no feedback regarding the success of an ECG transmission. This paper describes the development of an inexpensive iPhone application that transmits ECG images over the AT&T data network to the hospital prior to a patient's arrival. The application is designed to dovetail with the existing STEMI-care protocol used by Charlottesville-area Emergency Medical Technicians (EMTs), and it provides a novel red/green light indicator predicting successful receipt of the image within two minutes. The goal of the application is to improve process efficiency and information flow allowing the patient to receive early, appropriate care and the best chance for a successful recovery. Test results, including usability tests, show that the application fulfills all key requirements. A prototype of the application will be evaluated by Charlottesville area Emergency Medical Technicians prior to implementation in emergency response protocols and long term deployment elsewhere.","PeriodicalId":249301,"journal":{"name":"2012 IEEE Systems and Information Engineering Design Symposium","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132875282","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}

NextGen will fundamentally change NAS operations by implementing advanced technologies to monitor and operate aircraft. NextGen poses substantial systems integration challenges due to numerous technical, organizational, political, and social perspectives and their complex interdependencies. Specifically, this paper addresses the challenges associated with integrating Unmanned Aircraft Systems (UAS) into the NAS, utilizing systems-of-systems methodology to identify and assess the integration risks. The team started by studying simple systems-of-systems to explore how modeling such systems can be applied to more complex systems, such as NextGen. Due to NextGen's evolving nature, the team adopted a dynamic methodological roadmap to guide risk assessment. The roadmap, an iterative methodological approach, involves developing (i) a comprehensive Hierarchical Holographic Model to identify the UAS shared state variables that contribute most to potential risk resulting from UAS integration into the NAS, (ii) a list of risk scenarios that are critical for UAS integration into the NAS, (iii) a process for risk modeling, planning, assessment, management, and communication utilizing multi-objective decision tree analysis, and (iv) recommendations for applying lessons learned from analyzing UAS integration to other components of NextGen. Whereas the results of this study are focused on UAS integration into the NAS, the methodological roadmap and modeling techniques adopted in this study are general enough to be applied to other systems-of-systems supported by MITRE Corporation. The results of this study are expected to help MITRE and the FAA navigate other NAS integration challenges and benefit from the political, social and ethical implications of UAS integration.","PeriodicalId":249301,"journal":{"name":"2012 IEEE Systems and Information Engineering Design Symposium","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127281395","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}

To improve spectrum utilization and increase potential revenues, the creation of a secondary market is essential. Opportunistic trading in a secondary market raises the possibility of interference (i.e. a situation in which a given spectrum band is over utilized thus reducing its quality of service). Thus, an auction mechanism for the redistribution of spectrum rights in a secondary market must satisfactorily address the possibility of interference. This work focused on the experimental evaluation of various auction mechanisms for spectrum allocation, primarily the Truthful Multichannel Auction (TMCA) developed by Barrera, Garcia, and Hong. Designs were evaluated based on revenue generation, allocative efficiency and incentive compatibility (including the possibility of collusion). The simulation software suite, Netlogo, was used in modeling versions of the mechanism. The auction scheme utilizes a conflict graph to model interference between auction bidders in which adjacent nodes cannot be allocated the same channel. This interference graph is used to create supply curves for each participating bidder based on conflicting bids. To test performance the results from human experimental auctions were compared with the optimal simulated results. These results show the validity of the Truthful Multichannel Auction's incentive structure and dictate recommendations for further modifications.","PeriodicalId":249301,"journal":{"name":"2012 IEEE Systems and Information Engineering Design Symposium","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124364003","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}
