This project involves the design and construction of a Climate Adaptable Solar Energy (CASE) System that aims to address the performance reduction due to changing environmental conditions. The CASE System is a biomimetic design, inspired by lichen, and applies biological concepts of protection and energy conversion to achieve adaptability. Symbiotic organisms of fungus and algae within lichen organisms exhibit environmental adaptability through close integration, thus living as a single organism. DSSCs were implemented as the driving mechanisms for harnessing energy for the system from the sun, just as algae performs in lichen. Dye-sensitized solar cells (DSSCs), which currently convert up to 15 percent of solar energy into electrical energy, are cheaper to manufacture than traditional photovoltaic systems, offer greater mechanical durability, and are a rising competitor for the current solar energy system market. Since the DSSCs were commercially unavailable, the DSSCs were assembled from core components contained in a kit. Additional pieces of the CASE System were designed and manufactured to perform functions similar to a fungus in a lichen organism, by providing protection and temperature control to the DSSCs.","PeriodicalId":441073,"journal":{"name":"2014 Systems and Information Engineering Design Symposium (SIEDS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114321608","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}

Problems such as communication failures, damaged infrastructure, violence, looting, and corrupt officials are examples of obstacles that aid organizations face. The inability to plan relief operations during disaster situations leads to greater human suffering and wasted resources. Our team used the Global Database of Events, Location, and Tone (GDELT), a machine-coded database of international events, for all of the models described in this paper. We produced a range of predictive models for the occurrence of violence in Sudan, including time series, general logistic regression, and random forest models using both R and Apache Mahout. We also undertook a validation of the data within GDELT to confirm the event, actor, and location fields according to specific, pre-determined criteria. Our team found that, on average, 81.2 percent of the event codes in the database accurately reflected the nature of the articles. The best regression models had a mean square error (MSE) of 316.6 and the area under the receiver operating characteristic curve (AUC) was 0.868. The final random forest models had a MSE of 339.6 and AUC of 0.861. Using Mahout did not provide any significant advantages over R in the creation of these models.","PeriodicalId":441073,"journal":{"name":"2014 Systems and Information Engineering Design Symposium (SIEDS)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128145501","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}

The major contributor to LOC accidents is pilot spatial disorientation (SD), which accounts for roughly 32% of all LOC accidents. A pilot experiences SD during flight when he/she fails to sense correctly the motion, and/or attitude of the aircraft. In essence, the pilot's expectation of the aircraft's state deviates from reality. This deviation results from a number of underlying mechanisms of SD, such as distraction, failure to monitor flight instruments, and vestibular illusions. Previous researchers have developed computational models to understand those mechanisms. However, the models are limited in scope, as they do not model pilot expertise and have a small span of flight regimes to test with. This research proposes a new pilot model to predict the best-possible-pilot-expectation of the aircraft state given vestibular and visual cues. The proposed pilot model is in the form of a model-based observer (MBO), which provides the infrastructure needed to establish an expert pilot model. Experts are known to form an internal model of the operated system due to training/experience, which allows the expert to generate internal expectations of the system states. Pilot's internal expectations are enhanced by the presence of information fed through the pilot's sensory systems. The proposed pilot model integrates a continuous vestibular sensory model and a discrete visual-sampling sensory model to take account for the influence of the pilot's sensory system on his/her expectation of the aircraft state. The computational model serves to investigate the underlying mechanisms of SD during flight and provide a quantitative analysis tool to support flight deck and countermeasure designs.","PeriodicalId":441073,"journal":{"name":"2014 Systems and Information Engineering Design Symposium (SIEDS)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132520429","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 considers the opposite to the interdiction problem, selecting facilities to maximize coverage after the worst-case interdiction. Solutions to this problem would inform facility placement when intentional disruption is feared, or when guaranteeing minimum coverages in the presence of random facility outages. Several approaches to the problem are considered, primarily derivatives of approaches to the structurally similar maximum coverage problem. An integer linear program formulation proves infeasible for problems of even modest size, despite exclusion of many non-binding constraints, but heuristic approaches (again adaptations of maximum coverage heuristics) show promise in both efficiency and solutions quality.","PeriodicalId":441073,"journal":{"name":"2014 Systems and Information Engineering Design Symposium (SIEDS)","volume":"8 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":"114954495","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}

The study of close packing will provide effective methods for geometric placement for self-organizing systems in order to minimize the area used for a given number of units, as well as the logistical task of populating a circuit board with a large number of cylindrical components. The focus of this research is to establish a framework for analyzing concentric close packing geometry for large systems.

When water vapor combines with soot and other particulate matter, condensation trails (contrails) can form and persist in Ice Supersatured Regions (ISSR). Analysis of 45 days of varying atmospheric configurations showed that the location of ISSR can vary between Flight Level (FL) 267 to Flight Level 414, and are most prevalent in the summer months. This paper describes the design of a decision support system to assist in the flight planning of short, medium, and transcontinental routes to avoid the ISSR. The decision support system includes two independent input variables and five output dependent variables. Based on the length of the flight, and the amount of ISSR avoidance, the system can present a tradeoff analysis between (i) the miles of contrails formed, (ii) the amount of fuel consumed, (iii) the time spent in air, (iv) the distance traveled, and (v) the amount of CO2 produced. Results for a normal day's flight schedule for 45 days of ISSR configurations shows that the airline flight routes provide both warming and cooling radiative heating effects that are sensitive to the meteorological conditions and time of day (i.e. solar azimuth). Over the course of long flights, ISSR avoidance caused the aircraft to fly about two percent further; while contrail avoidance on short flights caused up to five percent or more increase in distance. Based on the analysis using the system, it is recommended that all flights over stage length of 1,000 nm be required to avoid ISSR because the radiative forcing due to contrails is tends to be greater than the radiative forcing caused by excess CO2 emissions to avoid contrail regions.","PeriodicalId":441073,"journal":{"name":"2014 Systems and Information Engineering Design Symposium (SIEDS)","volume":"23 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":"114720187","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}

Conventional cell culturing is a manual process in which cells are grown in a controlled environment and eventually harvested for testing purposes. The large amount of human labor necessary in this process creates opportunity for human error that limits cell culture quality. Taking steps towards automation involved the design and implementation of three subsystems: one for environmental management; another for fluid handling; and a third for controls and communication. Following development of the subsystems, a series of tests were performed to validate functionality and provide a basis for complete integration of all systems. Complete automation of the process will solve several challenges encountered during traditional cell culturing including tight control of the growth environment, eliminating contamination, maintaining many cultures simultaneously, and maintaining consistency and quality.","PeriodicalId":441073,"journal":{"name":"2014 Systems and Information Engineering Design Symposium (SIEDS)","volume":"56 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":"124226124","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 overcome this issue, NASA's Advanced Exploration Systems Radiation Works Storm Shelter Team (RadWorks) has been testing different radiation protective habitats to shield against the onset of solar particle event radiation. These habitats have the capability of protecting occupants by utilizing logistics such as food, water, brine, human waste, trash, and non-consumables to build short-term shelters. Protection comes from building a barrier with the logistics that dampens the impact of the radiation on astronauts. The goal of this research is to develop a discrete event simulation, modeling a solar particle event and the building of a protective shelter. Two different locations, the main hallway and the crew quarters, within a larger habitat that is similar to the layout of the International Space Station (ISS) are modeled and compared. The outputs from this model will yield three results: 1) provide the team with information on the amount of protection the crew members receive based on the two structures, 2) provide the amount of time for setting up the habitat during specific points in a mission given an event occurs, 3) and determine the total areas covered on the shelter by the different logistics.","PeriodicalId":441073,"journal":{"name":"2014 Systems and Information Engineering Design Symposium (SIEDS)","volume":"38 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":"129576419","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}
