Design of an Underwater Video and GPS Mapping System for the Exploration of Streambed Aquatic Populations

This design project was initiated due to the need for an underwater video mapping system optimized for exploration along the streambed or riverbed and under rocks. Such a system would be used for population mapping of fish and other aquatic species. The system also needed to incorporate global positioning system data with the visual data. The current prototype successfully fulfills the requirements for underwater practicality and visual and GPS data collection. It incorporates a compact waterproof camera with Sony lens, two Fenix high-intensity waterproof flashlights for illumination, a handheld DVR for recording video, and a Garmin 60CSx GPS unit. The two data streams are collected constantly and merged such that GPS data at a frequency of one hertz synchronizes seamlessly with the video stream. Initial testing has shown success with the current prototype; video quality is sufficient for identification of species and GPS data shows the location at which the video was taken with sufficient precision. Testing has been done on the Hiwassee River concerning Hellbender salamanders and numerous fish and crawfish species have been identified using the system on the Little Tennessee River. Using GPS and video, aquatic species numbers, locations, and habitat can be determined and mapped in ArcGIS

Integration of Spatial and Continuous Water Parameter Measurement with Existing Aquatic Habitat and Streambank Mapping Systems

Traditional water quality measurement techniques have evolved from ex-situ testing to multi-parameter in-situ testing of spatially discrete or temporally continuous samples. The next advancement of these techniques seeks to achieve spatially continuous sampling. By incorporating multi-parameter measurement into an existing spatially continuous river surveying platform with GPS location, a water quality map can be generated for any body of water. This project integrated a YSI 6920 Compact Sonde into the techniques of the streambank mapping platform previously developed at the University of Tennessee, Knoxville. For proof of concept, a section of the Tennessee River, specifically the confluence of the Holston River and French Broad River, was mapped via cross sections across the mixing zone. The intention was to assess water quality parameters at a point where differences in the two influents would be apparent. The expectation, and reality, is that the distinction between influents would become less distinct further from the confluence. A GIS plot of various parameters will be presented and demonstrates the gradient change across multiple river cross-sections, while supporting the anticipated pattern of the mixing zone; differing water quality between the Holston and French Broad Rivers will also be compared. Resultant data and the feasibility of collection support the continued use of multi-parameter water quality units with spatially continuous data systems

California's Arts and Cultural Ecology

Californians create, organize, and nurture one of the world's richest arts and cultural ecologies. Across diverse landscapes, they preserve traditions and unveil cutting-edge new artwork. As artists, cultural leaders, community-builders, and arts lovers, they build organizations that nurse creativity from conception through production, presentation, and participation.California's arts and cultural ecology encompasses complex ties among people, organizations, and places. An ecological approach underscores the prominence and contributions of these arts ecology components and how they can be strengthened, especially in times of economic austerity.California's arts and cultural nonprofits play an initiating and pivotal role in this ecology. They are important shapers of the state's internationally renowned cultural industries. They preserve, commission, and present a cornucopia of music, performance, heritage, and visual arts to people in all of the state's regions, across age groups and ethnicities at all levels of income and wealth.Our study documents the budget size, disciplinary focus, and intrinsic and economic impacts of nearly 11,000 California arts and cultural nonprofits, mapping them onto cities and regions. We use new data from the California Cultural Data Project, The National Center for Charitable Statistics, the American Community Survey, the Survey of Public Participation in the Arts, and Impact Analysis for Planning. To explore causal connections, we correlate elements of this mosaic with community characteristics. We detail how people work for the sector, volunteer, and make financial contributions. We show the overall impact of people and organizations on California's economy in terms of jobs, income, output, and state and local tax revenue. With interview data, we offer qualitative insights into governance, interorganizational relationships, and special challenges for small nonprofits. California's nonprofit arts and cultural organizationsCalifornia hosts more nonprofit arts and cultural organizations than do most of the world's nations. Their ranks include multipurpose cultural centers, science and visual arts museums, symphony orchestras and folk ensembles, artist service organizations, ethnic arts groups, literary societies, dance companies, professional associations, and many more. Some have no formal budgets, do little fundraising, and operate chiefly on energetic contributions of volunteers. Others manage sizable budgets with extensive staff, run large productions and venues, and rely less on volunteers.California's nearly 11,000 arts and cultural nonprofits operate across the state's regions. Smaller organizations vastly outnumber large ones, with 85% of organizational budgets falling under $250,000 and 48$25,000. Yet California's nonprofits have a much larger footprint than formal budgets convey, because at all budget sizes, they engage the services of substantial numbers of volunteers and receive in-kind contributions of time and materials uncommon in public and for-profit sectors.Reflecting California's ethnic diversity and its immigrant character, 22% of California's arts and cultural nonprofits focus on ethnic, folk arts, and multidisciplinary work. Another fifth focus on humanities, legacy, and other museums. Visual arts organizations, including art museums, comprise 5% of California nonprofits, but 10% of those with budgets over $10 million

Arts, Culture and Californians Charting Arts Participation and Organizations in a Vast, Diverse State

Arts and culture play a significant role in the daily lives of Californians. The state is noteworthy for the avid participation of its people, the diversity and abundance of its arts organizations and the varied regional characteristics of its arts sector. California's regions reflect distinctive populations, participation rates, numbers and types of arts and culture organizations, and levels of arts funding.These points are drawn from a new report, California's Arts and Cultural Ecology, created by Markusen Economic Research for The James Irvine Foundation. The report is based on data gathered from multiple sources describing the California arts and culture sector and public involvement, and includes a detailed technical appendix. Access the full research at www.irvine.org/ArtsEcology.Presented here in highlight form, this information is intended to guide the approaches of arts and culture leaders, funders and policymakers. It invites further investigation by interested researchers, and offers Californians deeper understanding of how they and their communities fit into the state's arts and culture ecology. Plus, it encourages the growing practice of integrating arts into initiatives in education, housing, health care and other areas of community well-being.The research featured here affirms, and extends well beyond, the economic benefits of arts and culture. It sheds new light on the role of this sector in the lives of Californians, illustrating its significance to people and communities throughout the nation's most-populated and diverse state.A note on participation. As new data sets and measures become available, future studies can more fully describe participation by including emerging ways people experience arts and culture, for example, through digital technology and via online communities. They may also further distinguish forms of deep engagement; for example, making art and practicing cultural traditions, versus attending events or exhibits

Impacts of Covid-19 mode shift on road traffic

This article is driven by the following question: as the communities reopen after the COVID-19 pandemic, will changing transportation mode share lead to worse traffic than before? This question could be critical especially if many people rush to single occupancy vehicles. To this end, we estimate how congestion will increases as the number of cars increase on the road, and identify the most sensitive cites to drop in transit usage. Travel time and mode share data from the American Community Survey of the US Census Bureau, for metro areas across the US. A BPR model is used to relate average travel times to the estimated number of commuters traveling by car. We then evaluate increased vehicle volumes on the road if different portions of transit and car pool users switch to single-occupancy vehicles, and report the resulting travel time from the BPR model. The scenarios predict that cities with large transit ridership are at risk for extreme traffic unless transit systems can resume safe, high throughput operations quickly.Comment: 14 pages, 11 figure

Brucella Abortus Infection in Man

From a survey of the complete table of results one finds that the largest proportion of cases occur in the byre workers, 50% of them showing agglutination with Br. abortus, and it is interesting to note that one of the other patients whose serum showed agglutination in a fairly high dilution 1:150 was employed in the byre up till January of this year when he was transferred to another part of the institution. No female cases were recorded in the series of results. None of the female patients worked in the byre, but milk from the farm played a large part in their diet. This fact seems to substantiate the view that direct contact with infected cattle is a more likely source of infection than the drinking of cow's milk. It has to be noted that half the cases occur in patients under 30 years of age, supporting the statement that in young patients the blood is more likely to contain agglutinins. Seven cases gave a titre of 1:50, i.e. 20 or 26 units, and from the negative history of any prolonged pyrexia it would seem to indicate that such a titre has little significance in the diagnosis of undulant fever due to Br. abortus. The diagnostic agglutination-titre has already been mentioned, but as yet there is no definitely accepted titre

Vehicle Multi-Pass Rut Volume and Mobility Power Study

This paper presents the relationship between applied power by a wheeled vehicle to soil and the rutting effects. Specifically, a strong positive relationship was found between cumulative applied power and total rut volume across multiple passes by the vehicle over the same tracks. Field-testing was conducted using a high-mobility multi-purpose wheeled vehicle (HMMWV) and two distinct soil types. Sensors on the vehicle measured torque and angular velocity of each of the four wheels, from which applied power was calculated. A rut profile meter was used to document the shape of the rut after set numbers of passes and this profile was used to calculate rut volume. These results are useful for determining vehicle mobility power requirements based on soil rutting during multi-pass operation
