Motion

This article is about orientation in the conceptual construction and exploration of the world. Orientations that fail to include a satisfactory definition of self as a vital component in ideas of explanation, compulsively leaning towards excessive analytical description(partism)) and resulting in increased numbers of empirically found exceptions to theoretical ideas, also fail to include adequate notions of motion and change. In the science of cognition a three part picture usually results, rather than a two component one in which the extraneous component functions as a compensation from the initial vagueness in ideas. Though this can seem to be a reasonable approach, to proceed from vagueness, to conjecture, empirical test/comparison, a false order in all components of a final theory will continuously result, and ultimately, in one to one correspondence, equate with a separate topic and not with the original. A compulsive and strict adherence to common sense, though not seeming to supply adequate explanation and strained for lingual description/expression, is the only possible route to adequate explanation. In cognition, the perennial stumbling is always at the division between the ethereal and the tangible. It is such an inhibitory obstacle, that in the construction of ideas, language falters to result in the continual construction of new words to “describe” rather than to connect. Though I believe “describe” is also the real ultimate goal, a real connection is never established

Cognition and Causation as Universal Phenomenom

A comment on the universality of all things

Symmetry and The Creative Cognition

An unconquered conceptual divide related to cognitive perception exists between the physical and biological sciences. The life processes of self assembly and replication are unaccounted for in quantum theory or in the ordinary laws of physics. Lying at the very base element of this confusion is a theoretical wall outlined by statistical generalization on one border, and exact historical evolution on the other. Can inert, randomly oriented, statistically described agents (atoms/molecules), direct the reproduction of like things. If the answer to this proposition is negative, then are space and matter not as assumed (i.e. – as uniformly interpretable statistical entities), but things with a life like evolving history from a unique beginning. For example: if life processes are conceptually tree like, can (must) the processes from which they are created be defined this way also? If one reflects on this question he can liken it to a similar question: can a tree exist with one branch only (i.e. can a tree exist as a simple line verses a line with an origin and history) a conflict emerges that reveals a subtler conflict in the pursuit of an objective interpretation. A simple line always is less complex than the other and does not exist in the life processes or even in the ordinary life of an individual: it's history, in terms of life time, is infinitely\ud smaller the closer it resembles a simple undefined line. In defining matter statistically, we are objectively claiming that it has no time dependant history, and yet is the objective source of evolution, which by definition has a subjective history. We are left with the alternative to find a new order for the definition of physical processes. In this paper, I wish to show that with very little rearrangement of current notions, a model of space can be created that details the replication, from an origin, and propagation in a tree like manner with a declining potential, of both the evolutionary processes of living things, and space, and matter

Aeroacoustics of subsonic turbulent shear flows

Sound generation in turbulent shear flows is examined. The emphasis is on simultaneous calculation of the turbulent flow along with the resulting sound generation rather than the alternative acoustic analogy approach. The first part of the paper is concerned with solid surface interaction. The second part concentrates on the sound generated by turbulence interacting with itself

A {\em local graph partitioning algorithm} finds a set of vertices with small conductance (i.e. a sparse cut) by adaptively exploring part of a large graph $G$, starting from a specified vertex. For the algorithm to be local, its complexity must be bounded in terms of the size of the set that it outputs, with at most a weak dependence on the number $n$ of vertices in $G$. Previous local partitioning algorithms find sparse cuts using random walks and personalized PageRank. In this paper, we introduce a randomized local partitioning algorithm that finds a sparse cut by simulating the {\em volume-biased evolving set process}, which is a Markov chain on sets of vertices. We prove that for any set of vertices $A$ that has conductance at most $\phi$, for at least half of the starting vertices in $A$ our algorithm will output (with probability at least half), a set of conductance $O(\phi^{1/2} \log^{1/2} n)$. We prove that for a given run of the algorithm, the expected ratio between its computational complexity and the volume of the set that it outputs is $O(\phi^{-1/2} polylog(n))$. In comparison, the best previous local partitioning algorithm, due to Andersen, Chung, and Lang, has the same approximation guarantee, but a larger ratio of $O(\phi^{-1} polylog(n))$ between the complexity and output volume. Using our local partitioning algorithm as a subroutine, we construct a fast algorithm for finding balanced cuts. Given a fixed value of $\phi$, the resulting algorithm has complexity $O((m+n\phi^{-1/2}) polylog(n))$ and returns a cut with conductance $O(\phi^{1/2} \log^{1/2} n)$ and volume at least $v_{\phi}/2$, where $v_{\phi}$ is the largest volume of any set with conductance at most $\phi$.Comment: 20 pages, no figure

Large N_c

The 1/N_c expansion of QCD with N_c=3 has been successful in explaining a wide variety of QCD phenomenology. Here I focus on the contracted spin-flavor symmetry of baryons in the large-N_c limit and deviations from spin-flavor symmetry due to corrections suppressed by powers of 1/N_c. Baryon masses provide an important example of the 1/N_c expansion, and successful predictions of masses of heavy-quark baryons continue to be tested by experiment. The ground state charmed baryon masses have all been measured, and five of the eight ground state bottom baryon masses have been found. Results of the 1/N_c expansion can aid in the discovery of the remaining bottom baryons. The brand new measurement of the \Omega_b^- mass by the CDF collaboration conflicts with the original D0 discovery value and is in excellent agreement with the prediction of the 1/N_c expansion.Comment: 4 pages, Invited talk at CIPANP 2009, May 26-31, 2009, to be published in the proceeding

Aircraft engine hot section technology: An overview of the HOST Project

NASA sponsored the Turbine Engine Hot Section (HOST) project to address the need for improved durability in advanced aircraft engine combustors and turbines. Analytical and experimental activities aimed at more accurate prediction of the aerothermal environment, the thermomechanical loads, the material behavior and structural responses to loads, and life predictions for cyclic high temperature operation were conducted from 1980 to 1987. The project involved representatives from six engineering disciplines who are spread across three work disciplines - industry, academia, and NASA. The HOST project not only initiated and sponsored 70 major activities, but also was the keystone in joining the multiple disciplines and work sectors to focus on critical research needs. A broad overview of the project is given along with initial indications of the project's impact
