Abstract: A system for solving equations of a given scientific code for a large dataset represented as a mesh includes first computing circuitry, second computing circuitry, and communication circuitry. The first computing circuitry includes software to arrange the mesh in a sequential order, and a memory to store the mesh data and the results obtained in the execution of the scientific code. The second computing circuitry includes software to execute the scientific code for one vertex of the mesh, and a cache memory to store all the neighboring vertices to the one vertex. The communication circuitry is between the first and second computing circuitry so that the first computing circuitry fed the second computing circuitry with the vertices of the mesh following the sequential order, and the scientific code is executed for all the vertices of the mesh and its results are returned to the first computing circuitry.

Abstract: The invention refers to systems and methods to optimize the memory and communications that suits the memory organization of many scientific codes, such as Computer Fluid Dynamics codes, that operate on meshes, such the mesh of an object that moves through a fluid medium. The methods adjust the order in which the data are used inside the algorithm, by means of traversing and ordering the mesh. This ordered mesh is streamed into the lower memory levels and allows for minimal data transfer requirements. The method also reduces the memory needs dramatically and improves the execution time of the scientific code. The systems and methods are particularly useful in the aeronautic industry for designing new aircrafts.

Abstract: A floating buoyant toy is made of one or more mylar, metallicized (coated) film, or elastomeric bladders, or closed envelopes, or balloons encompassing a fixed volume of matter that is lighter than the ambient surrounding matter, a like number of spindle and collar combinations or equivalent rotating structures for rotatably engaging each base or aperture of each balloon, each spindle and collar or each equivalent rotating structure being connected to the bottom of a balloon, each collar being adapted to spin around a spindle, and each spindle being connected at each end to a perimetric enclosure and forming a part thereof, the perimetric enclosure forming a circular ring having an inside diameter sufficient to allow each balloon to pass unencumberedly and repeatedly through the ring, one balloon at a time, as the ring is twirled between two aspects, for example, the right and left hands.
