Sampling, feasibility, and priors in Bayesian estimation

Creator:: Chorin, Alexandre J., Lu, Fei, Miller, Robert N., Morzfeld, Matthias, and Tu, Xuemin
Abstract:: Importance sampling algorithms are discussed in detail, with an emphasis on implicit sampling, and applied to data assimilation via particle filters. Implicit sampling makes it possible to use the data to find high-probability samples at relatively low cost, making the assimilation more efficient. A new analysis of the feasibility of...

Eliminating flutter for clamped von Karman plates immersed in subsonic flows

Creator:: Lasiecka, Irena and Webster, Justin
Abstract:: We address the long-time behavior of a non-rotational von Karman plate in an inviscid potential flow. The model arises in aeroelasticity and models the interaction between a thin, nonlinear panel and a flow of gas in which it is immersed [6, 21, 23]. Recent results in [16, 18] show that...

Flow-plate interactions: Well-posedness and long-time behavior

Creator:: Chueshov, Igor, Lasiecka, Irena, and Webster, Justin
Abstract:: We consider flow-structure interactions modeled by a modified wave equation coupled at an interface with equations of nonlinear elasticity. Both subsonic and supersonic flow velocities are treated with Neumann type flow conditions, and a novel treatment of the so called Kutta-Joukowsky flow conditions are given in the subsonic case. The...

Commensurable continued fractions

Creator:: Arnoux, Pierre and Schmidt, Thomas A.
Abstract:: We compare two families of continued fractions algorithms, the symmetrized Rosen algorithm and the Veech algorithm. Each of these algorithms expands real numbers in terms of certain algebraic integers. We give explicit models of the natural extension of the maps associated with these algorithms; prove that these natural extensions are...

The fundamental solution of linearized nonstationary navier-stokes equations of motion around a rotating and translating body.

Creator:: Farwig, Reinhard, Guenther, Ronald B., Thomann, Enrique A., and Necasova, Sarka
Abstract:: We derive the fundamental solution of the linearized problem of the motion of a viscous uid around a rotating body when the axis of rotation of the body is not parallel to the velocity of the uid at infinity.

Infinitely Many Lattice Surfaces with Special Pseudo-Anosov Maps

Creator:: Calta, Kariane and Schmidt, Thomas A.
Abstract:: We give explicit pseudo-Anosov homeomorphisms with vanishing Sah–Arnoux–Fathi invariant. Any translation surface whose Veech group is commensurable to any of a large class of triangle groups is shown to have an affine pseudo-Anosov homeomorphism of this type. We also apply a reduction to finite triangle groups and thereby show the...

The Elusive Pursuit of Interdisciplinarity at the Human–Environment Interface

Creator:: Roy, Eric D., Morzillo, Anita T., Seijo, Francisco, Reddy, Sheila M. W., Rhemtulla, Jeanine M., Milder, Jeffrey C., Kuemerle, Tobias, and Martin, Sherry L.
Abstract:: Environmental challenges are complex and require expertise from multiple disciplines. Consequently, there is growing interest in interdisciplinary environmental research that integrates natural and social science, an often arduous undertaking. We surveyed researchers interested and experienced in research at the human–environment interface to assess perspectives on interdisciplinary research. Integrative interdisciplinary research...

Quantity is Nothing without Quality: Automated QA/QC for Streaming Environmental Sensor Data

Creator:: Campbell, John L., Rustad, Lindsey E., Porter, John H., Taylor, Jeffrey R., Dereszynski, Ethan W., Shanley, James B., Gries, Corinna, Henshaw, Donald L., Martin, Mary E., Sheldon, wade M., and Boose, Emery R.
Abstract:: Sensor networks are revolutionizing environmental monitoring by producing massive quantities of data that are being made publically available in near real time. These data streams pose a challenge for ecologists because traditional approaches to quality assurance and quality control are no longer practical when confronted with the size of these...

Responsible Aquaculture in 2050: Valuing Local Conditions and Human Innovations Will Be Key to Success

Creator:: Diana, James S., Egna, Hillary S., Chopin, Thierry, Peterson, Mark S., Cao, Ling, Pomeroy, Robert, Verdegem, Marc, Slack, William T., Bondad-Reantaso, Melba G., and Cabello, Felipe
Abstract:: As aquaculture production expands, we must avoid mistakes made during increasing intensification of agriculture. Understanding environmental impacts and measures to mitigate them is important for designing responsible aquaculture production systems. There are four realistic goals that can make future aquaculture operations more sustainable and productive: (I) improvement of management practices...

Abstract:: To maximize the utility of research to decisionmaking, especially given limited financial resources, scientists must set priorities for their efforts. We present a list of the top 40 high-priority, multidisciplinary research questions directed toward informing some of the most important current and future decisions about management of species, communities, and...
