As water moves downstream, it carries sediments that become sorted and rounded. The purpose of this research project is to determine the water content of soil, overall composition of sediments (gravel, sand, etc.), and grain size changes (if it does change) along a river profile, using a creek that runs through the Indiana University-Purdue University Fort Wayne (IPFW) campus. In the 2014 Fall semester, grain size distribution analysis was performed on 14 soil samples collected along the length of the creek. Fourteen soil samples were also collected from same sites in the 2015 Spring and Fall semesters resulting in three sets of data. Collected data indicates water content and grain size distribution vary along the creek profile. Water content for the Fall 2014 samples has a range of ~20 -28%. This is closely mimicked with the Fall 2015 samples with a range 20-25%. However the Spring 2015 data begins ~28% and falls to ~24% over the course of the creek profile. This could be due to a higher influx of water during the spring season keeping the sediments waterlogged. Certain soil samples contained significantly lower water content than others, that, when examined more closely, revealed different soil profiles containing less silt-clays and higher sand-gravel. The soil composition data ranges from coarse to fine grained sands, silts, and clays with less gravel present in the recent samples. This could be due to heavy flooding experienced in this area as well as recent construction on campus. Knowing the cause(s) of finning sediments downstream in the creek may help in managing the stream and probably other rivers in northern Indiana. This is an ongoing research and new data will be presented.http://opus.ipfw.edu/stu_symp2016/1037/thumbnail.jp

The purpose of this project is to design a “Shared Space” that can be used as a multi-functional space for learning and collaborative activities. The users of this shared space include interior design students from the Latin University of Costa Rica and local interior design professionals. This “Shared Space” project is located in Santa Maria de Dota, Costa Rica, which is known for its coffee plantation and is a beautiful place to sit back to enjoy the wonderful natural surroundings. Unfortunately, deforestation has become a forefront issue in recent years in Santa Maria de Dota area that causes farmers to develop new ideas for coffee plantations in order to have more sun exposure for coffee plants. Local people in Santa Maria de Dota also have initiated a strategy of reducing water and energy consumption by using organic materials. This project is inspired by the concept of sustainability in the coffee industry and strategies of addressing the issue of deforestation. In this “Shared Space” facility, specific spaces for different activities are provided, such as a learning studio space for students, a place to meet and greet clients, spaces for collaboration with communities, offices for interior designers, and a place to showcase their design work. “Shared Space” fosters communication and collaboration between students, professionals, educators and communities. By integrating multiple functions, technologies, and interactions between team members, educators, and clients, a shared space can be used for collaboration among different levels of students in the service-learning model. Also these spaces can provide a more private space to support individual research. The design goal was to alleviate the issue of deforestation while providing a place for education and collaboration with the community. In order to be sustainable, it is important to incorporate recyclable materials and products in the design. Bamboos are used as the primary building material. Replacing timber is another approach to reduce deforestation. In addition, the design incorporates local products such as reusing defective coffee beans as wall partitions and reusing burlap bags left over from the coffee in attempt to keep the cost low for the Santa Maria de Dota economy. Another strategy to tackle deforestation in the design is to grow trees within “Shared Space” as decoration and replant them out in the community once they have outgrown the facility. The design approach has both purpose and impact of fostering education and community collaboration while promoting of designing a sustainable environment.http://opus.ipfw.edu/stu_symp2016/1011/thumbnail.jp

The current standard of wound assessment is heavily dependent on manual measurements and visual inspection. This approach has areas that need to be improved to provide a better quality service to patients and to enhance the accuracy of the assessment. Some of existing steps can be digitally automated and the image data can be properly stored for later computation and analysis. These steps will reduce inconvenience for the patient and increase accuracy for wound care. This project is a creation of a prototype system that allows a team of medical practitioners to remotely record data of a patient’s wounds and then assess the healing process of the patient’s wounds with the assistance of computers and domain experts at a medical office. The system is developed as a web application, connected with a back-end sub-system including a database. By using a front-end graphical user interface, such as through the Internet or on a mobile phone, a local medical practitioner can capture the images of wounds at a patient’s location and request an evaluation by physicians who are located at their medical office. The physician remotely assesses the transmitted images and is able to give feedback or a diagnosis in real time. This assessment procedure provides a convenience to patients who are experiencing lack of mobility. This also enables the patients to receive high quality services from medical professionals at other facilities. In addition, the developed system improves the quality of service by utilizing a computer-assisted measuring process on the digitized images. This developed system will also allow color/shape tracking of the image in order to automatically measure the wound’s dimensions. Lastly, the data can be digitally archived and has the ability to be used for historical comparison to keep track of the wound’s healing progress with annotations attached to the image. The Senior Capstone team’s role in this project is the initialization of the WoundView system and the aforementioned tasks. Our sponsor institution is Parkview’s Mirro Center for Research and Innovation. This project has future potential to contribute greatly to the under-developed branch of telemedicine due its ability to be improved and expanded on. One such example includes deriving the wound depth and volume from the images. Another could include image morphing the progress of the healing wound through 3D modeling.http://opus.ipfw.edu/stu_symp2016/1004/thumbnail.jp

Significant reductions in the cost of solar photovoltaic modules have been coupled with the emergence of innovative financial tools and resulted in dramatic increases in the development of distributed renewable energy generation systems. The deep penetration of solar energy throughout our nationu27s electric sector is dependent on successfully integrating distributed generation, storage, and demand management systems. Achieving this challenge will require improvements to component technologies coupled with paradigm shifts in how energy systems and controls are conceived, developed, tested, and deployed in the marketplace. An integrative approach to meet this challenge is presented including the formation of a collaboration platform for academic and industry partners that is coordinated around a physical smart grid test bed embedded in a large unregulated electric grid. The value adding processes of this ecosystem for research, education, and market deployment are described based on two years of operation. Specific strategies for the advancement of smart grid solutions leading to the deep penetration of renewable energy are also presented including topics of distributed generation, energy efficiency, advanced metering and controls, and cyber security. Implications of these strategies on research, education, and workforce development are also described

What began as a professor’s classroom illustration to encourage students to take climate change seriously sparked a student movement that transformed Eastern University into a leader in environmental stewardship and social responsibility. How did this happen at an evangelical university in a conservative coal state that, at the time, was producing 1% of the world’s climate change gases? Using the method of autoethnography, the author provides an explanation that involves political opportunity structures (recent legal changes now allowed consumers to purchase clean energy from the electrical grid), the influence of ideas (the professor had published a theory about the transformative influence of environmental education—students challenged her to operationalize the theories), intentional strategizing (by students who implemented best practices from other universities), student government (who conducted meetings across campus before holding a senate vote) and political struggle between university administrators and students that was only resolved after the student body president obtained media coverage by The Philadelphia Inquirer. What really lit a fire under the student body, however, went beyond theory frames, politics, legal changes, social movement strategies, student government or individual charisma. Some might call it serendipity. By 2003, 37% of Eastern University’s electricity came from wind energy. Within two years, Eastern University had 100% of the electricity for the main campus generated by wind energy. In 2004, they added a 56 kilowatt solar system to the roof of the Eagle Learning Center. On February 2, 2012, Eastern University made a seven-year commitment to 100% clean energy for the main campus. This is the story of the transformative and enduring influence of environmental education at Eastern University and the sociomaterial learning that influenced collective identity formation and student activism

As part of a senior capstone course, one of the graduating students developed a tutorial to enhance online learning. After surveying current students and collaboration with the health sciences librarian and faculty, two priorities for improvement emerged. These were identified as ways to help students work in groups and use discussion forums more effectively. This presentation will include sharing what was learned through the literature, a tutorial that was developed for students and how the effectiveness of the teaching strategy is being evaluated.

Worm propagation models are important for understanding worm dynamics and designing effective and efficient detection and defence systems. The existing models, however, ignore the heterogeneity in vulnerable hosts and assume that the worm-scanning rate is the same for all infected hosts. In this work, we analytically and empirically study the impact of heterogeneity of vulnerable hosts on worm propagation. Specifically, we first apply the Jensenu27s inequality to show that the heterogeneity in vulnerable hosts indeed hinders the speed of worm propagation. Next, we propose a novel model to predict and characterise worm dynamics among heterogeneous vulnerable hosts. Finally, applying the real trace from Center for Applied Internet Data Analysis (CAIDA) to simulate the propagation of a Witty worm in the Internet, we verify our analytical results and demonstrate that our proposed model can accurately predict the spread of worms among heterogeneous vulnerable hosts

Recent efforts to engage more explicitly with the interpretation of emotions in archaeology have sought new approaches and terminology to encourage archaeologists to take emotions seriously. This is part of a growing awareness of the importance of senses—what we see, smell, hear, and feel—in the constitution and reconstitution of past social and cultural lives. Yet research on emotion in archaeology remains limited, despite the fact that such states underpin many studies of socio-cultural transformation. The Archaeology of Anxiety draws together papers that examine the local complexities of anxiety as well as the variable stimuli—class or factional struggle, warfare, community construction and maintenance, personal turmoil, and responsibilities to (and relationships with) the dead—that may generate emotional responses of fear, anxiousness, worry, and concern. The goal of this timely volume is to present fresh research that addresses the material dimension of rites and performances related to the mitigation and negotiation of anxiety as well as the role of material culture and landscapes in constituting and even creating periods or episodes of anxiety

Property management is an important aspect in sustaining the Earth’s ecosystems. Anthropogenic changes to the planet have made conservation important in maintaining species abundance and diversity as well as limit damages to sensitive ecosystems. Invasive species have become a standard, consistent problem in managed ecosystems. Such species often invade into disturbed areas, which commonly are a result of restoration or other management activities. In dredging open water bodies at Eagle Marsh Nature Preserve (Allen County, IN), artificial mounds were constructed with the soil removed. This movement of soil created a disturbance which facilitated for the recruitment and colonization of invasive species. The purpose of this study was to quantify the effectiveness of transferring a native seed bank in a mesic prairie to the artificial mounds as a method of controlling invasive species. The native seed bank in the mesic prairie would be lost due to additional management. This study was conducted with greenhouse and field experimentation. Soil samples containing the seed bank were moved to a greenhouse to quantify plant emergence following different intact and mixed soil treatments. All emerging plant species were identified and counted. All treatment methods contained a high diversity of native species and a low diversity of invasive species with the exception of the seed bank soil mixed with soil from the mounds. The mound mixed soil contained a higher diversity of invasive species than other treatments. A plant survey of the mounds was conducted in July 2014. In October 2014, 960 m2 of soil was transferred from the donor site to the mounds. A post-move survey conducted in July 2015 indicated the native species diversity increased while the diversity of invasive species decreased. Soil transfer as a management strategy was appropriate in this situation where a large native seed bank in a donor region existed. By moving soil from one location to another, we were able to promote native plant establishment and reduce invasive species emergence. While soil transfer is effective, other management strategies may not have the same results. Callery pear (Pyrus calleryana) is an invasive tree introduced to North America as an ornamental from southwest Asia. It easily invades disturbed areas, causing a disruption to mid- to late-successional species establishment. The purpose of this study was to assess Callery pear demographics in a managed prairie and quantify the effects of a prescribed fire management strategy on Callery pear density and recruitment. This study was conducted at Arrowhead Prairie (Allen County, IN), managed by Little River Wetlands Project (LRWP). Before 2009, Arrowhead Prairie was primarily used for agriculture. Following LRWP acquisition, the property has undergone active management including native plant seeding and prescribed fire. The prairie was divided into a north and south section using a historic ditch, with the south section burned in April 2014 and the north section burned in May 2015. Bare seeds, fruit, first-year seedlings, and second-year seedlings were also burned in a separate controlled experiment. Fire in both years top killed Callery pear individuals, with 100% of surveyed trees producing epicormic shoots and 83% producing more than one epicormic sprout. First-year seedlings exposed to the fire had a 3% resprout rate while all seconds-year seedlings resprouted. In contrast, 13% of individuals at Arrowhead Prairie had epicormic shoots without fire. Trees were significantly shorter post-burn than prior to the burn; however, root collar diameter was not different, suggesting that resources were used in primary growth. While fire did reduce stem height, it did increase the number of stems occurring within the burned section due to epicormic sprouting. Root stored reserves provided necessary energy to produce numerous sprouts by the majority of pear trees, although no trees produced flowers during the duration of the study. Plant age likely plays an important role in response to fire, with seeds and fruits succumbing. However, older seedlings may survive with increased epicormic shoot production. Multiple techniques combined with relevant studies allows for land managers to make appropriate decisions in terms of management. Although many of these techniques are not universal, a wide range of researched techniques provides multiple avenues of approach when managing a parcel of land

Mobile processors continue to increase in performance while becoming more power efficient, providing consumers with improved gaming, multi-media, and browsing, along with longer lasting device usage. To keep up with consumer multimedia demand, mobile processor manufacturers have begun to integrate Graphical Processing Units (GPU) on mobile processors, providing users with the high performance graphics required for mobile gaming applications. The addition of integrated GPUs to the mobile processors also offers new opportunities for introducing to the mobile platform computationally intensive algorithms that were formerly impractical when running on the mobile CPU processor alone. GPU manufacturers such as NVIDIA are scaling down their GPU architecture from desktop systems to those developed for use on mobile processors, such as the Tegra K1, featuring a single GPU processing core. This research effort investigates the performance of the computationally intensive Continuous Space Language Model (CSLM) algorithm on the NVIDIA Tegra K1 mobile processor and compares its performance on this platform to that of the desktop GPU platform reported by Thompson et al. [1]. The performance on the embedded GPU platform will also be compared to that of a conventional embedded CPU. However, first, the execution time of the algorithm will be observed while executing on a laptop CPU platform to provide a reference point for the performance of the Tegra K1 CPU processor(s). Next, the algorithm will be configured to execute solely on the Tegra K1 CPU processor(s), and the execution time will be observed. Finally, the execution time of the algorithm will be observed after porting only the computationally intensive portions of the algorithm to the Tegra K1 GPU while other portions remain on the embedded CPU

The Panel, Building on Foundations: Creating Multiple Methodological Spaces in Media Studies won the Top Panel Award. Panelists will discuss how to build on foundations of traditional media research and use multiple methodological approaches in conjunction with one another. By engaging with multiple methods together—including rhetorical criticism with ethnographic field methods, critical rhetoric and performance with documentary, qualitative and quantitative methods of analysis, and critical/cultural analysis with autoethnography—panelists offer ways to take media studies into the future and offer insights that could not be accessed without using multiple methods together. In addition to Dr. Herbig, the panel included: Potentials of Rhetorical and Ethnographic Methods for Examining Production, Representation, and AudienceJennifer C.
