Monitoring Groundwater Properties within a Wetland on the IPFW Campus
No full textYEATER, Rossand ISIORHO, K. Solomon A., Geosciences, Indiana University - Purdue University Fort Wayne (IPFW), 2101 E. Coliseum Blvd, Fort Wayne, IN 46805-1499, [email protected] Groundwater testing and monitoring is a crucial part of environmental management for urban and rural settings. This study examines the water chemistry in a well field located at Indiana University-Purdue University Fort Wayne (IPFW) campus in order to determine the contaminant and thus the water quality in the campus. The well field at the IPFW campus is located by a creek that drains into the St. Joseph River. Nitrate, nitrite pH, temperature, conductivity, total dissolved solids, dissolved oxygen and head elevation were measured over a 56 day testing period (late September – mid November) in 15 of the 20 installed wells. Soil samples were also collected from a burrow pit at the location to determine the hydraulic conductivity of the soil.
The hydraulic conductivity (k value) was obtained using Hazen method and aided the determination of beds. The nitrate and nitrite levels ranged from 0.0 – 20.9 and 0.0 – 0.029 mg/L, respectively. A few readings were above EPA regulated contaminant levels for drinking water (10 and 1.0 mg/L for nitrate and nitrite respectively. Trends of nitrate and nitrite often show an inverse relationship, suggesting that nitrate is being reduced to nitrite via iron content and/or organic activity. There is a positive correlation between the head elevation and dissolved oxygen (DO) with the seasonal decrease in temperature. Grid wells that have elevations varying less that one inch are assumed to penetrate the same layer and head differences of these wells were used to determine the flow direction, which is northwest. This is in agreement with previous studies under the assumption that the creek is an influent stream and receives runoff and drainage from the IPFW campus. New data will be presented as it is an ongoing research project.

Waldere: Fragments of a Lost and Forgotten Epic
No full textMy research focuses on the Waldere fragments, and their place within the broader scope of Old English literature. The Waldere fragments are an under-studied and under-represented piece of literature within the corpus of medieval English texts, despite their significance as one of the only pieces of secular poetry alongside the more well-known Beowulf. My research project analyzes and contextualizes the content of the fragments within the corpus of Old English secular poetry, and Old English literature as a whole. Through careful examination of digital facsimiles of the fragments provided on the website of the National Library of Denmark and Copenhagen University Library, I examined the content of the piece and analyzed its position within the larger body of work outside of Old English concerned with the legend of Walter of Aquitaine, the central figure of the fragments. These fragments, which were incorporated into the binding of an Elizabethan prayer book sometime in the 16th century, are further indication of the warrior culture of the Anglo-Saxons, as well as proof of the popularity of legends like that of Walter. I also argue that the fragments’ fate, that of being used as binding for a religious tome, also displays the shift that occurred within the culture of the British Isles between the creation of the manuscript sometime around the year 1000 C.E. and its destruction for alternate use sometime in the 16th century. The shift from a culture connected deeply to its roots in warrior culture, while simultaneously devoutly Christian, to one of less violent piety, is apparent through the fate of such artifacts like Waldere. The study of manuscripts such as this is one of the few ways in which we can learn more about the multi-faceted culture of the earliest speakers of English.http://opus.ipfw.edu/stu_symp2016/1008/thumbnail.jp

Modeling the Silicon Brain:Introducing a Paradigm to Simulate the Human NervousSystem Utilizing Microcontrollers and Microcomputers
No full textUntil very recently, the world of robotics has been an exclusive and imposing field due, in part, to both the high cost of purchasing specialized robots and the steep learning curve, thus excluding the field from the immense pool of resources and ingenuity that exists in the open source and DIY communities. In this poster we present a way to overcome these obstacles and make the world of robotics research and development more of an inclusive environment for non-academic individuals using the ArPi Method for Robotic Construction. This method aims to utilize inexpensive microcontrollers and processors, wired together to mimic the neuroanatomy of a human, to construct highly skilled, artificially intelligent robots capable of performing tasks with the same degree of ability as more costly commercial products. This focus on easily accessible components, already well-used in the open-source community, creates a gentle transition for those already in the community to become acquainted with the method, and the focus on ease of use creates a gentler learning curve for non-academics to begin creating quickly. We demonstrate the abilities of this method by creating a simple wall-following agent capable of maneuvering through a maze using two components already common in the open-source community: the Arduino Microcontroller and Raspberry Pi Microcomputer. We wired these together in such a manner that information streaming from an iCreate 2 robot base about relative wall distance from the agent is piped through one Arduino and aggregated, processed and reasoned over by a series of two interconnected Raspberry Pi’s, the second of which sends information about the decided action sequence to a second Arduino, who creates and sends instructions about movement to the iCreate 2 robotic platform to carry out.http://opus.ipfw.edu/stu_symp2016/1060/thumbnail.jp
Reconnecting the Lines
No full textThe purpose of this project is to design a “Vertical Studio” that can be used as a multi-functional space for learning and collaborative activities. The users of this vertical studio include interior design students from California State University and local interior design professionals as well as community people. This “Vertical Studio” project is located in downtown Sacramento, California, judged as one of the top ten worst metropolitan areas for air pollution by the U.S. Environment Protection Agency. One of the main causes for this is emissions from mobile sources. This design project – reconnecting the lines strives to enlighten the Sacramento community on how to preserve the environment and restore their city by providing students and community people with a shared learning environment. This “Vertical Studio” serves as a place where students and community can collaborate for the education on the importance of environmental sustainability and air quality both inside and outside built environment. This “Vertical Studio” project fosters an interactive learning process that allows everyone to be involved and to make downtown Sacramento a wholesome place to thrive and revitalize. In this “Vertical Studio” facility, specific spaces for different activities are provided, such as an inviting lobby, a room to greet the community that meets American Disability Act (ADA) standards, informal and formal meeting areas for students, design professionals and community people, and an appealing studio space where students and professionals can work collaboratively. The studio space is designed with multi-purpose functionality in mind. Many of the rooms or areas can be rearranged and adapted to accommodate other activities. This design promotes the use of sustainable design principles and the considerations of indoor and outdoor air quality in built environment. By utilizing a vertical studio model with a focus on service learning, the goal of applying sustainable design principles in design process can be achieved through collaborations with the community. On the other hand, service learning helps connecting academics with communities. This in turn helps the students to apply problem solving skills in actual settings while offering a service to help resolve the community environmental issues.http://opus.ipfw.edu/stu_symp2016/1030/thumbnail.jp
Long-Term Spectrum Monitoring with Big Data Analysis and Machine Learning for Cloud-Based Radio Access Networks
No full textSpectrum monitoring is important for efficient spectrum sharing and resource management in cloud-based radio access networks (C-RAN). In this paper we show how data obtained from long-termspectrum monitoring together with machine learning (ML) operating on big data (BD) can be used in a C-RAN scenario for spectrum management purposes. We propose an approach for spectrumoccupancy forecasting which can be used to reduce the delay in making dynamic spectrum allocation decisions and improve the cognitive and management functionalities of cloud-based architectures such as C-RAN. The spectrum occupancy and usage activity in a predefined frequency band is based on the statistical processing of a large amount of collected data and the introduction of a frequency–time resources indicator as a measure of spectrum usage. Furthermore, we apply ML algorithms to predict spectrum usage and compare the predicted with actual measured data. Taking into consideration that the accuracy of the prediction depends on the volume of collected data and the time of prediction on the BD and ML approach, we propose the development of a cloud-based generic processing architecture to solve the “accuracy versus latency” trade-off problem. The proposed architecture is appropriate for deployment in cognitive C-RAN
Hierarchical Archimedian Copula Models for the Analysis of Binary Familial Data
No full textFamilial binary data are the dichotomous responses along with covariates collected from family members. The dependence among the members is very important in modeling this type of data. In this presentation, hierarchical Archimedian copula models are proposed to model the data with the dependence taken into consideration, and various hierarchy strategies are also compared using a real life example
The Healing Colors of Andrea del Sarto’s Gambassi Altarpiece
No full textAndrea del Sarto, a Florentine painter of considerable talent, produced his Gambassi Altarpiece (1527-1528) as a response to a particularly vicious outbreak of plague. This paper describes the innovative nature of that response. I argue that Andrea’s colore—that is, his glittering treatment of light, color, and atmosphere—engages with sophisticated discussions of Renaissance art theory, with longstanding medical beliefs regarding the spread of contagion, as well as with ancient traditions of theological inquiry concerning spiritual renewal and healing. It my contention that, when considered within the context of sixteenth-century devotional practices, Andrea’s painting—his colore, in particular—offers spectators special reassurances that, in turn, resonate with the way Europeanists are coming to discuss the idea of “resilience” today. In this sense, my paper not only speaks to pressing and current concerns among scholars in the Early Modern field. It also has exciting implications for the study of Europe’s artistic and religious histories, broadly conceived
