title: Encircling Singularities of a Serial Robot

description: The folder Animations of Anthropomorphic Arm with Spherical Wrist contains animation of this wrist-separable robot encountering coincident overhead and wrist singularities.

Counter to intuition, a displacement path where the arm motion is minimal at singularity encounter switches solution branches associated with the arm singularity, whereas an encounter where the arm swings through 180-deg remains on the same solution branch. The same holds for wrist motion and whether the wrist solution switches branches. In the animation files in two formats named RobotZeroSelfMotions, the wrist and arm appear nearly stationary during the singularity encounter, but that both the arm and the wrist have switched branches is apparent from both the arm and wrist rotation being reset at the repeat of the animation cycle. In RobotTwoSelfMotions, both the wrist and arm undergo large motions at singularity encounter, but that both wrist and arm remain on the same solution branch is demonstrated by the lack of a reset in either wrist or arm placement when an animation cycle repeats.

This minimal-motion singularity encounter shown in RobotZeroSelfMotions computes the animation path automatically using the singularity encirclement procedure. Other animations show combinations of remaining on or switching between either or both of the wrist and arm solution branches. These singularity encounters use the encirclement procedure to reach the self-motion path of the wrist. Following the wrist self-motion path reaches the self-motion path of the arm. Where to switch between or exit either of these self-motion paths was determined manually from plots of finite-displacement departures from these paths. Automatically generating singularity encounters that enter and exit self-motion paths is considered for future work.

Because the encirclement path results in small angle displacements of the robot, the portions of the animations on the encirclement path appear to casual viewing as hesitations in the robot motion. Careful scrutiny reveals these small motions, distinguishing the half-turn to transit the singularity encounter without following self-motion paths from the quarter-turn to reach the wrist self-motion.

The folder Serial robot models contains solid models representing four serial robot architectures. The open-source Open SCAD software available at openscad.org allows viewing these robot models from different viewpoints. 

The file numerics.zip contains the QR matrix decomposition Java software used to conduct the encirclement procedure. This modification of the QR solver from the public-domain JAMA linear algebra package for Java https://math.nist.gov/javanumerics/jama/ has these enhancements.

title: West Africa Dataset of Impervious Surface Change (WADISC) from 2001 – 2020

description: Rapid urbanization in most African countries is increasing impervious surfaces, including building roofs, glass, concrete, asphalt, and paved roads. However, regionally consistent urban data are lacking to support large-scale research and assessment of impervious surface expansion and its impacts on urban heat islands, hydrology and flood risk, infectious disease risk, cropland and biodiversity loss, habitat fragmentation, and carbon sequestration. The West Africa Dataset of Impervious Surface Change (WADISC) uses all available Landsat data to map urban change in Ghana, Togo, Benin, and Nigeria. The approach combines machine learning algorithm with LandTrendr time series analysis to generate annual maps of urban impervious surface cover from 2001 - 2020. The overall mean absolute error was less than 6% cover and the root mean squared error was less than 10% cover, giving us confidence that the predictions can effectively distinguish areas with high versus low impervious cover. We further classified the impervious cover into developed (pixel value is greater than 20%) and undeveloped (pixel value is less than or equal to 20%) with 93% overall accuracy and approximately similar producer (79%) and user (80%) accuracies in developed areas. WADISC is available in two forms: 1) continuous impervious cover with values ranging from 0% – 100% and 2) Developed area classification with pixel values of 1 and 0, representing the presence and absence of developed area. These data can support consistent city, national and regional assessments and research on urbanization and its impacts.WADISC_Impervious.zip contains GeoTIFF files with continuous impervious cover data from 2001-2020.WADISC_Developed.zip contains GeoTIFF files with classified developed area data from 2001-2020.

description: UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.
