    Description:

    This multilayered spreadsheet is used to assist aspiring homeowners design their home from a pre-set list of options for floorplans, finishes, fixtures, and basic services. It also rapidly calculates an estimated total cost for the structure as well as a corresponding monthly payment amount. This allows the design process to be performed iteratively, giving families autonomy in the design of their own home, the chance to consider a variety of options and combinations, and the immediate knowle…

    Description:

    This tool calculates the design loads on a reinforced concrete special moment frame with a concrete slab roof, determines force and moment demands through an approximate portal frame analysis, assesses load combinations, evaluates the capacity of members compared to the demands, and approximates the cost of needed construction materials. It was produced by MSCE student Christianos Burlotos in order to parametrically assess frames to determine the best-fit frame for single-family homes in Leog…

    Description:

    Synthesis problems for linkages in kinematics often yield large structured parameterized polynomial systems which generically have far fewer solutions than traditional upper bounds would suggest. This paper describes statistical models for estimating the generic number of solutions of such parameterized polynomial systems. The new approach extends previous work on success ratios of parameter homotopies to using monodromy loops as well as the addition of a trace test that provides a stopping…

    Description:

    Polynomials which arise via elimination can be difficult to compute explicitly. By using a pseudo-witness set, we develop an algorithm to explicitly compute the restriction of a polynomial to a given line. The resulting polynomial can then be used to evaluate the original polynomial and directional derivatives along the line at any point on the given line. Several examples are used to demonstrate this new algorithm including examples of computing the critical points of the discriminant locu…

    This dataset contains the raw and sanitized data about Curate privacy settings, collected April 2nd, 2020 from the CurateND anotation test server, along with the R code used to convert the raw data to the sanitized data. The data is being used as part of INF 7491, a graduate-level data analysis course held Winter Semester 2020 at Wayne State University.

    The raw data consists of a RDF entries for every attribute in every CurateND pid, stored as RDF triples. The processed data is stored a an …

    Description:

    Alt’s problem, formulated in 1923, is to count the number of four-bar linkages whose coupler curve interpolates nine general points in the plane. This problem can be phrased as counting the number of solutions to a system of polynomial equations which was first solved numerically using homotopy continuation by Wampler, Morgan, and Sommese in 1992. Since there is still not a proof that all solutions were obtained, we consider upper bounds for Alt’s problem by counting the number of sol…
