Code from: Fast and robust curve skeletonization for real-world elongated objects

    This record contains C++ code as well as a Docker release for performing curve skeletonization of objects, which have a voxel representation. Curve skeletonization is used to convert a three-dimensional digital object or shape to locally one-dimensional parts; in other words, to reduce the shape information to a more easily processed form. Our algorithm does so for objects whose surface may be noisy, which is a common occurrence when working with data acquired under real-world conditions. This record also includes a test dataset for verifying that the code is running correctly and as examples of how to convert from different file types.

    Legume (Fabaceae) Fruits and Seeds Version 2

      This is an identification key to genera for seeds and fruits of the legume family. The coverage is world wide, and for each genus there are descriptions of the seeds and fruits, distribution data, and images. The interactive software system INTKEY is used for accessing the data and images. The key can be used for identifying to genus unknown legume samples or for querying the data and images for legume genera, and is designed for seed analysts, technicians, port inspectors, weed scientists, ecologists, botanists, and researchers who need to identify isolated legume fruits and seeds.

      Product system model for distributed renewable syngas production

        This product system model represents the generation of two co-products from forest or wood product mill operation residues using the Tucker Renewable Natural Gas (RNG) Thermochemical conversion process. The two co-products are a synthesis gas (syngas) and biochar (a form of charcoal made from woody biomass via pyrolysis, used as a soil amendment, and under investigation as an approach to carbon sequestration to produce negative carbon dioxide emissions). Data for this process were collected in St. Regis, Montana and Locust, NC, where the Tucker RNG conversion process has been tested and demonstrated.

        Unit process data for bio-jet fuel production from poplar biomass via bioconversion at a biorefinery

          A partial Life Cycle Assessment (LCA) is conducted to investigate the life cycle impacts of a biorefinery designed to convert poplar tree chips into jet fuel via fermentation and subsequent hydrogenation. The goal of producing jet fuel from Populus (poplar) trees (bio-jet) is to create an alternative to petroleum based jet fuel (petro-jet). Currently no jet fuel producing biorefineries are in commercial operation and the results of this LCA will be used to assess a potential environmental impact that could result from scaling up the proposed system. Work is part of the Advanced Hardwood Biofuels Northwest project.

          Agricultural Model Intercomparison and Improvement Project (AgMIP) Tools

            Agricultural Model Intercomparison and Improvement Project (AgMIP) datasets are stored in the harmonized AgMIP Crop Experiment (ACE) format. Translation tools available for download at [http://tools.agmip.org/](http://tools.agmip.org/) allow re-formatting of the data to model-specific formats for various crop simulation models.

            Agricultural Conservation Planning Framework (ACPF) Toolbox

              The Agricultural Conservation Planning Framework (ACPF) Toolbox software includes tools to process the LiDAR-based digital elevation models for hydrologic analysis, which then allows a series of prioritization, riparian classification, and conservation-practice placement tools to be used. These toolsets identify agricultural fields most prone to deliver runoff directly to streams, map and classify riparian zones to inform whole-watershed riparian corridor management, and estimate the extent of tile drainage in the watershed. The software maps out suites of locations appropriate to install each of several types of conservation practices. These practice-placement opportunities are mapped for practices including controlled drainage, grassed waterways, water and sediment control basins, and nutrient removal wetlands. Rather than making any recommendations, ACPF provides an inventory of watershed assessment data and conservation placement opportunities across a watershed, in order to inform local watershed planning.
