Gloucester Marine Station: Future Development Feasibility Study, Jack F. Ahern, Ben Eli Webb

Landscape Architecture & Regional Planning Studio and Student Research and Creative Activity

The study commenced in July 2009 with historical research about the site and its context, site analysis, including the existing conditions and development regulations. This analysis included: topography, soils, vegetation, structures, utilities, easements, property deed, and city, state, and federal regulations. From this analysis an assessment of future development potentials was made based on the existing data/documents from UMass files, public records, Mass GIS data, site visits, and interviews with Gloucester, Commonwealth of Massachusetts, and other officials and stakeholders. From the assessment we identified potential future uses, building locations, and feasible alternative layouts of the site. These alternatives were summarily …

The Office For Harmonization In The Internal Market: Creating A 21st Century Public Agency, Jane Fountain, Raquel Galindo-Dorado, Jeffrey Rothschild

National Center for Digital Government

(first paragraph) President Wubbo de Boer and his department directors, his top management team, prepared for critical meetings of the Administrative Board and the Budget Committee in the winter of 2010. The European Union’s trademark and design registration agency in Alicante, Spain, grandly named the Office of Harmonization for the Internal Market (Trade Mark and Design) (OHIM), had exceeded all expectations for the establishment of the Community trade mark (CTM) and the Registered Community design (RCD). The new agency also could be proud of impressive achievements in productivity and transparency since it began registering trademarks in 1996. Through productivity gains, …

Western Woburn Greenway Study, Jennifer H. Masters, Bryan C. Aldeghi, Eric C. Kells, Maureen C. Pollock, Rebekah Lynne Decourcey, Carol Waag, Youjin Kwon, Kathryn E. Ostermier, Patrick T. Mcgeough, Ryan Patrick Ball

Landscape Architecture & Regional Planning Studio and Student Research and Creative Activity

In spring 2010, the Department of Landscape Architecture and Regional Planning at the University of Massachusetts Amherst was asked to complete a landscape planning study, the “Western Woburn Greenway Study” for the City of Woburn, MA. The study was undertaken by a team of graduate students, supervised by Professor Jack Ahern. The goals of that study are as follows.

The City of Woburn currently has two large parcel groups of undeveloped land, Whispering Hill (the north focus area) and Winning/Shannon Farms (the south focus area) that are, or may become, available for acquisition (see “Scope of Project” below). The first …

Effects Of Long-Range Nonlinear Interactions In Double-Well Potentials, C Wang, Pg Kevrekidis

Mathematics and Statistics Department Faculty Publication Series

We consider the interplay of linear double-well-potential (DWP) structures and nonlinear longrange interactions of different types, motivated by applications to nonlinear optics and matter waves. We find that, while the basic spontaneous-symmetry-breaking (SSB) bifurcation structure in the DWP persists in the presence of the long-range interactions, the critical points at which the SSB emerges are sensitive to the range of the nonlocal interaction. We quantify the dynamics by developing a few-mode approximation corresponding to the DWP structure, and analyze the resulting system of ordinary differential equations and its bifurcations in detail. We compare results of this analysis with those produced …

Nonlinear Waves In Disordered Diatomic Granular Chains, Laurent Ponson, Nicholas Boechler, Yi M. Lai, Mason A. Porter, Pg Kevrekidis

Mathematics and Statistics Department Faculty Publication Series

We investigate the propagation and scattering of highly nonlinear waves in disordered granular chains composed of diatomic (two-mass) units of spheres that interact via Hertzian contact. Using ideas from statistical mechanics, we consider each diatomic unit to be a “spin,” so that a granular chain can be viewed as a spin chain composed of units that are each oriented in one of two possible ways. Experiments and numerical simulations both reveal the existence of two different mechanisms of wave propagation: in low-disorder chains, we observe the propagation of a solitary pulse with exponentially decaying amplitude. Beyond a critical level of …

A Note On The Non-Commutative Laplace–Varadhan Integral Lemma, W De Roeck, C Maes, K Netocny, L Rey-Bellet

Mathematics and Statistics Department Faculty Publication Series

We continue the study of the free energy of quantum lattice spin systems where to the local Hamiltonian H an arbitrary mean field term is added, a polynomial function of the arithmetic mean of some local observables X and Y that do not necessarily commute. By slightly extending a recent paper by Hiai, Mosonyi, Ohno and Petz [10], we prove in general that the free energy is given by a variational principle over the range of the operators X and Y. As in [10], the result is a non-commutative extension of the Laplace–Varadhan asymptotic formula.

Matter-Wave Dark Solitons: Stochastic Versus Analytical Results, Sp Cockburn, He Nistazakis, Tp Horikis, Pg Kevrekidis, Np Proukakis, Dj Frantzeskakis

Mathematics and Statistics Department Faculty Publication Series

The dynamics of dark matter-wave solitons in elongated atomic condensates are discussed at finite temperatures. Simulations with the stochastic Gross-Pitaevskii equation reveal a noticeable, experimentally observable spread in individual soliton trajectories, attributed to inherent fluctuations in both phase and density of the underlying medium. Averaging over a number of such trajectories (as done in experiments) washes out such background fluctuations, revealing a well-defined temperature-dependent temporal growth in the oscillation amplitude. The average soliton dynamics is well captured by the simpler dissipative Gross-Pitaevskii equation, both numerically and via an analytically derived equation for the soliton center based on perturbation theory for …

Existence And Stability Of Multisite Breathers In Honeycomb And Hexagonal Lattices, V Koukouloyannis, Pg Kevrekidis, Kjh Law, I Kourakis, Dj Frantzeskakis

Mathematics and Statistics Department Faculty Publication Series

We study the existence and stability of multisite discrete breathers in two prototypical non-square Klein–Gordon lattices, namely a honeycomb and a hexagonal one. In the honeycomb case we consider six-site configurations and find that for soft potential and positive coupling the out-of-phase breather configuration and the charge-two vortex breather are linearly stable, while the in-phase and charge-one vortex states are unstable. In the hexagonal lattice, we first consider three-site configurations. In the case of soft potential and positive coupling, the in-phase configuration is unstable and the charge-one vortex is linearly stable. The out-of-phase configuration here is found to always be …

Constructing Weyl Group Multiple Dirichlet Series, G Chinta, Pe Gunnells

Let be a reduced root system of rank . A Weyl group multiple Dirichlet series for is a Dirichlet series in complex variables , initially converging for sufficiently large, that has meromorphic continuation to and satisfies functional equations under the transformations of corresponding to the Weyl group of . A heuristic definition of such a series was given by Brubaker, Bump, Chinta, Friedberg, and Hoffstein, and they have been investigated in certain special cases by others.

In this paper we generalize results by Chinta and Gunnells to construct Weyl group multiple Dirichlet series by a uniform method and show in …
