AbstractMuck thickness measurements are necessary for guiding muck dredging projects within the Indian River Lagoon (IRL), a coastal estuary that covers one third of Florida's east coast. Marine Resources Council, Florida Institute of Technology, and Brevard County Natural Resources Management successfully engaged Brevard County citizens in the Muck Finders program, a muck research initiative that was designed to help quantify and prioritize muck management actions in the IRL. This program utilizes citizen science as a cost-effective means to expedite the collection of scientifically valid data. Volunteer citizen scientists are given the education, training, and equipment needed to collect scientifically valid data to verify the presence and depth of muck at various locations within the IRL. In 2017, citizen scientists of this program contributed over 300 volunteer hours, collecting muck thickness data at over 750 individual sites. A statistical comparison of muck thickness measurements to duplicate measurements collected by volunteer citizen scientists has confirmed method reliability. Muck thickness maps created from this scientifically valid data aid regulatory agencies to identifying areas where muck dredging will have the most impact.

AbstractBenthic filter feeding organisms have the potential to improve local water quality by filtering microalgae and particulate matter out of the water column. A pilot project was conducted to test the concept of creating a Living Dock by growing these filter feeders at a dock in the Indian River Lagoon. Two different methods (mats and bags) were tested for their ability to recruit benthic organisms, as well as the efficacy of these methods for use as a long-term citizen science project. Eighteen oyster mats were wrapped around dock pilings, and 18 oyster bags were suspended between pilings of the same dock. After 1 year of immersion, healthy populations of barnacles, sponges, algae, bryozoans, mussels, and tunicates were found growing on both the bags and the mats. During that same time period, live oysters were also found growing on both mats and bags, with a maximum of 73 live oysters in one bag. Although the total percent cover of organisms settling on the shells did not differ between the mats or the bags, there was significantly greater organismal diversity in the bag treatment compared to the mat treatment. Bags were a more effective recruiter of benthic organisms, but longevity was an issue, with bags becoming heavily fouled and often breaking loose from the dock over time. It was noted that the mats with the higher shell densities saw greater recruitment and had greater diversity. Although the bags proved to be a better alternative than mats for the recruitment and growth of benthic organisms, they are not sustainable for use as a citizen science project. Future efforts should consider constructing mats with high-density shell counts, as the mats have more durability and are better suited for citizen scientists.

How do you successfully engage volunteers in citizen science projects? In recent years, citizen science has grown considerably in popularity, resulting in rapid increases in the number of citizen science and crowdsourcing projects and providing cost-effective means for scientists to gather more data over broader spatial ranges to tackle research questions in a wide variety of scientific, conservation, and environmental fields Bonney et al. 2016, Aceves-Bueno et al. 2017. While the proliferation of such projects has produced a growing abundance of citizen scientist-generated data and published research informed by citizen science methods Follett and Strezov 2015, this also means that volunteers have a greater number of projects competing for their time. When faced with an increasingly-crowded landscape, how can you generate interest in a citizen science or crowdsourcing project and maintain contributions over the project’s lifetime? The Biodiversity Heritage Library (BHL) supports a variety of citizen science and crowdsourcing projects, from transcribing field notes to tagging scientific illustrations with taxonomic names on Flickr and enhancing data for 19th century periodicals through its Zooniverse-based Science Gossip project. Through a variety of outreach strategies including collaborative social media campaigns, partnerships with citizen science communities, and interactive incentives, BHL has successfully engaged volunteers with diverse projects to enrich the library’s data and increase discoverability of its collections. This presentation will discuss outreach strategies for citizen science projects that BHL has undertaken to further support research initiatives with our content. In addition, the presentation will share lessons-learned and offer suggestions that attendees can apply to their own citizen science engagement efforts.

Abstract Over the last few decades, finite element analysis has become an integral part of the overall tire design process. Engineers need to perform a number of different simulations to evaluate new designs and study the effect of proposed design changes. However, tires pose formidable simulation challenges due to the presence of highly nonlinear rubber compounds, embedded reinforcements, complex tread geometries, rolling contact, and large deformations. Accurate simulation requires careful consideration of these factors, resulting in the extensive turnaround time, often times prolonging the design cycle. Therefore, it is extremely critical to explore means to reduce the turnaround time while producing reliable results. Compute clusters have recently become a cost effective means to perform high performance computing (HPC). Distributed memory parallel solvers designed to take advantage of compute clusters have become increasingly popular. In this paper, we examine the use of HPC for various tire simulations and demonstrate how it can significantly reduce simulation turnaround time. Abaqus/Standard is used for routine tire simulations like footprint and steady state rolling. Abaqus/Explicit is used for transient rolling and hydroplaning simulations. The run times and scaling data corresponding to models of various sizes and complexity are presented.

The UK Construction Industry through its Government Construction Strategy has recently been mandated to implement Level 2 Building Information Modelling (BIM) on public sector projects. This move, along with other initiatives is key to driving a requirement for 25% cost reduction (establishing the most cost-effective means) on. Other key deliverables within the strategy include reduction in overall project time, early contractor involvement, improved sustainability and enhanced product quality. Collaboration and integrated project delivery is central to the level 2 implementation strategy yet the key protocols or standards relative to cost within BIM processes is not well defined. As offsite construction becomes more prolific within the UK construction sector, this construction approach coupled with BIM, particularly 5D automated quantification process, and early contractor involvement provides significant opportunities for the sector to meet government targets. Early contractor involvement is supported by both the industry and the successive Governments as a credible means to avoid and manage project risks, encourage innovation and value add, making cost and project time predictable, and improving outcomes. The contractor is seen as an expert in construction and could be counter intuitive to exclude such valuable expertise from the pre-construction phase especially with the BIM intent of äóÖbuild it twiceäó», once virtually and once physically. In particular when offsite construction is used, the contractoräó»s construction expertise should be leveraged for the virtual build in BIM-designed projects to ensure a fully streamlined process. Building in a layer of automated costing through 5D BIM will bring about a more robust method of quantification and can help to deliver the 25% reduction in overall cost of a project. Using a literature review and a case study, this paper will look into the benefits of Early Contractor Involvement (ECI) and the impact of 5D BIM on the offsite construction process.

Increases in the world’s population and population density promote the spread of emerging pathogens. Vaccines are the most cost-effective means of preventing this spread. Traditional methods used to identify and produce new vaccines are not adequate, in most instances, to ensure global protection. New technologies are urgently needed to expedite large scale vaccine development. mRNA-based vaccines promise to meet this need. mRNA-based vaccines exhibit a number of potential advantages relative to conventional vaccines, namely they (1) involve neither infectious elements nor a risk of stable integration into the host cell genome; (2) generate humoral and cell-mediated immunity; (3) are well-tolerated by healthy individuals; and (4) are less expensive and produced more rapidly by processes that are readily standardized and scaled-up, improving responsiveness to large emerging outbreaks. Multiple mRNA vaccine platforms have demonstrated efficacy in preventing infectious diseases and treating several types of cancers in humans as well as animal models. This review describes the factors that contribute to maximizing the production of effective mRNA vaccine transcripts and delivery systems, and the clinical applications are discussed in detail.

We present a new method for correcting the amplitudes of arrivals in an acoustic finite-difference simulation for elastic effects. In this method, we selectively compute an estimate of the error incurred when the acoustic wave equation is used to approximate the behavior of the elastic wave equation. This error estimate is used to generate an effective source field in a second acoustic simulation. The result of this second simulation is then applied as a correction to the original acoustic simulation. The overall cost is approximately twice that of an acoustic simulation but substantially less than the cost of an elastic simulation. Because both simulations are acoustic, no S-waves are generated, so dispersed converted waves are avoided. We tested the characteristics of the method on a simple synthetic model designed to simulate propagation through a strong acoustic impedance contrast representative of sedimentary geology. It corrected amplitudes to high accuracy for reflected arrivals over a wide range of incidence angles. We also evaluated results from simulations on more complex models that demonstrated that the method was applicable in realistic sedimentary models containing a wide range of seismic contrasts. However, its accuracy was reduced for wide-angle reflections from very high impedance contrasts such as a shallow top-salt interface. We examined the influence of modeling at coarse grid resolutions, in which converted S-waves in the equivalent elastic simulation are dispersed. These results provide some validation for the accuracy of the method when applied using finite-difference grids designed for acoustic modeling. The method appears to offer a cost-effective means of modeling elastic amplitudes for P-wave arrivals in a useful range of velocity models. It has several potential applications in imaging and inversion.
