  • Combinatorial Design University of Southern California Non-Parametric Computational Design Strategies
    Jose Sanchez Combinatorial design University of Southern California Non-parametric computational design strategies 1 ABSTRACT This paper outlines a framework and conceptualization of combinatorial design. Combinatorial 1 Design – Year 3 – Pattern of one design is a term coined to describe non-parametric design strategies that focus on the permutation, unit in two scales. Developed by combinatorial design within a game combination and patterning of discrete units. These design strategies differ substantially from para- engine. metric design strategies as they do not operate under continuous numerical evaluations, intervals or ratios but rather finite discrete sets. The conceptualization of this term and the differences with other design strategies are portrayed by the work done in the last 3 years of research at University of Southern California under the Polyomino agenda. The work, conducted together with students, has studied the use of discrete sets and combinatorial strategies within virtual reality environments to allow for an enhanced decision making process, one in which human intuition is coupled to algo- rithmic intelligence. The work of the research unit has been sponsored and tested by the company Stratays for ongoing research on crowd-sourced design. 44 INTRODUCTION—OUTSIDE THE PARAMETRIC UMBRELLA To start, it is important that we understand that the use of the terms parametric and combinatorial that will be used in this paper will come from an architectural and design background, as the association of these terms in mathematics and statistics might have a different connotation. There are certainly lessons and a direct relation between the term ‘combinatorial’ as used in this paper and the field of combinatorics and permutations in mathematics.

    The Book Review Column1 by William Gasarch Department of Computer Science University of Maryland at College Park College Park, MD, 20742 email: [email protected] In this column we review the following books. 1. Combinatorial Designs: Constructions and Analysis by Douglas R. Stinson. Review by Gregory Taylor. A combinatorial design is a set of sets of (say) {1, . , n} that have various properties, such as that no two of them have a large intersection. For what parameters do such designs exist? This is an interesting question that touches on many branches of math for both origin and application. 2. Combinatorics of Permutations by Mikl´osB´ona. Review by Gregory Taylor. Usually permutations are viewed as a tool in combinatorics. In this book they are considered as objects worthy of study in and of themselves. 3. Enumerative Combinatorics by Charalambos A. Charalambides. Review by Sergey Ki- taev, 2008. Enumerative combinatorics is a branch of combinatorics concerned with counting objects satisfying certain criteria. This is a far reaching and deep question. 4. Geometric Algebra for Computer Science by L. Dorst, D. Fontijne, and S. Mann. Review by B. Fasy and D. Millman. How can we view Geometry in terms that a computer can understand and deal with? This book helps answer that question. 5. Privacy on the Line: The Politics of Wiretapping and Encryption by Whitfield Diffie and Susan Landau. Review by Richard Jankowski. What is the status of your privacy given current technology and law?

  • Modules Over Semisymmetric Quasigroups
    Modules over semisymmetric quasigroups Alex W. Nowak Abstract. The class of semisymmetric quasigroups is determined by the iden- tity (yx)y = x. We prove that the universal multiplication group of a semisym- metric quasigroup Q is free over its underlying set and then specify the point- stabilizers of an action of this free group on Q. A theorem of Smith indicates that Beck modules over semisymmetric quasigroups are equivalent to modules over a quotient of the integral group algebra of this stabilizer. Implementing our description of the quotient ring, we provide some examples of semisym- metric quasigroup extensions. Along the way, we provide an exposition of the quasigroup module theory in more general settings. 1. Introduction A quasigroup (Q, ·, /, \) is a set Q equipped with three binary operations: · denoting multiplication, / right division, and \ left division; these operations satisfy the identities (IL) y\(y · x)= x; (IR) x = (x · y)/y; (SL) y · (y\x)= x; (SR) x = (x/y) · y. Whenever possible, we convey multiplication of quasigroup elements by concatena- tion. As a class of algebras defined by identities, quasigroups constitute a variety (in the universal-algebraic sense), denoted by Q. Moreover, we have a category of quasigroups (also denoted Q), the morphisms of which are quasigroup homomor- phisms respecting the three operations. arXiv:1908.06364v1 [math.RA] 18 Aug 2019 If (G, ·) is a group, then defining x/y := x · y−1 and x\y := x−1 · y furnishes a quasigroup (G, ·, /, \). That is, all groups are quasigroups, and because of this fact, constructions in the representation theory of quasigroups often take their cue from familiar counterparts in group theory.

Matthias Beck Associate Professor of Mathematics Felix Breuer Federico Ardila Associate Professor of Mathematics ON THE POLYHEDRAL GEOMETRY OF t{DESIGNS Steven Collazos San Francisco State University 2013 Lisonek (2007) proved that the number of isomorphism types of t−(v; k; λ) designs, for fixed t, v, and k, is quasi{polynomial in λ. We attempt to describe a region in connection with this result. Specifically, we attempt to find a region F of Rd with d the following property: For every x 2 R , we have that jF \ Gxj = 1, where Gx denotes the G{orbit of x under the action of G. As an application, we argue that our construction could help lead to a new combinatorial reciprocity theorem for the quasi{polynomial counting isomorphism types of t − (v; k; λ) designs.

    Essay‐Contest 2017/18 Leon Ritterbach, International School Kufstein, 9. Schulstufe, Fremdsprachenerwerb: 5 Jahre Scott Duncan Tremaine Astrophysics is a very interesting field of science. You explore the whole universe, from tiny Asteroids to huge black holes. Every time you solve one of the mind breaking riddles that the universe has to offer, it raises new questions. You can find out how the universe works and how forces like gravity form the universe we know and act on us. Scott Duncan Tremaine is one of the people who were lucky enough to be able to study astrophysics. Today, he is 68 years old and one of the world’s leading astrophysicists. He is a fellow of the Royal Society and a member of the National Academy of Sciences. He made predictions about planetary rings, has written an outstanding book “Galactic Dynamics” and named the Kuiper belt. Scott Tremaine’s research is focused on the dynamics of a wide range of astrophysical systems, including planetary rings, comets, planetary systems, galaxies, and clusters of galaxies (structures that consists of anywhere from hundreds to thousands of galaxies). He is known for his contributions to the theory of Solar Systems, Galactic Dynamics and his prediction of small moons keeping the belts of planets in place. Tremaine is so popular that there is even an asteroid named after him, 3806 Tremaine.

The 1889 oil painting suggests how the night sky might look if all of the mass in the universe were luminous. Observations of galaxy dynamics and modern theories of galaxy formation imply that the visible components of galaxies, composed mostly of stars, lie at the centers of vast halos of dark matter that may be 30 or more times larger than the visible galaxy. In most models of galaxy formation, the halos are comparable in size to the distance between galaxies. The halos form as a result of the gravitational instability of small density fluctuations in the early universe; the star-forming gas collects at the minima of the halo potential wells. Infall of outlying material into existing halos and mergers of small halos with larger ones continue at the present time. If the halos were visible to the naked eye, there would be well over 1000 nearby galaxies with halo diameters larger than the full Moon.

    Polyharmonic homogenization, rough polyharmonic splines and sparse super-localization. Houman Owhadi,∗ Lei Zhang,y Leonid Berlyand z June 13, 2013 Abstract We introduce a new variational method for the numerical homogenization of di- vergence form elliptic, parabolic and hyperbolic equations with arbitrary rough (L1) coefficients. Our method does not rely on concepts of ergodicity or scale-separation but on compactness properties of the solution space and a new variational approach to homogenization. The approximation space is generated by an interpolation basis (over scattered points forming a mesh of resolution H) minimizing the L2 norm of the source terms; its (pre-)computation involves minimizing O(H−d) quadratic (cell) problems on (super-)localized sub-domains of size O(H ln(1=H)). The result- ing localized linear systems remain sparse and banded. The resulting interpolation basis functions are biharmonic for d ≤ 3, and polyharmonic for d ≥ 4, for the op- erator − div(a∇·) and can be seen as a generalization of polyharmonic splines to differential operators with arbitrary rough coefficients. The accuracy of the method (O(H) in energy norm and independent from aspect ratios of the mesh formed by the scattered points) is established via the introduction of a new class of higher- order Poincar´einequalities. The method bypasses (pre-)computations on the full domain and naturally generalizes to time dependent problems, it also provides a natural solution to the inverse problem of recovering the solution of a divergence form elliptic equation from a finite number of point measurements.
