description: Loosely coupled programming is a powerful paradigm for rapidly creating higher-level applications from scientific programs on petascale systems, typically using scripting languages. This paradigm is a form of many-task computing (MTC) which focuses on the passing of data between programs as ordinary files rather than messages. While it has the significant benefits of decoupling producer and consumer and allowing existing application programs to be executed in parallel with no recoding, its typical implementation using shared file systems places a high performance burden on the overall system and on the user who will analyze and consume the downstream data. Previous efforts have achieved great speedups with loosely coupled programs, but have done so with careful manual tuning of all shared file system access. In this work, we evaluate a prototype collective IO model for file-based MTC. The model enables efficient and easy distribution of input data files to computing nodes and gathering of output results from them. It eliminates the need for such manual tuning and makes the programming of large-scale clusters using a loosely coupled model easier. Our approach, inspired by in-memory approaches to collective operations for parallel programming, builds on fast local file systems to provide high-speed local file caches for parallel scripts, uses a broadcast approach to handle distribution of common input data, and uses efficient scatter/gather and caching techniques for input and output. We describe the design of the prototype model, its implementation on the Blue Gene/P supercomputer, and present preliminary measurements of its performance on synthetic benchmarks and on a large-scale molecular dynamics application.

description: An artwork is made based on a personal hypothesis resting on the existing knowledge of the artist. This knowledge, whether from a case study within a theme the artist is researching or from his or her general understanding/reception of the world where he/she is working, will inevitably cause the artwork to be of a personal and subjective matter, regardless of the proposition or matter discussed in the work itself. With this in mind, the idea of an auto analysis of one’s work seems somewhat unproductive as one enters the analysis or critique of one’s work with the same knowledge or moral as the work was initially based. With this in mind my intention with this text was to create a paper that would be an opportunity to demonstrate something about my work and its context, rather than demonstrating my knowledge. By leaving the raw material of my sources as untouched as possible I hoped with this approach to present a process that would embody the sensation of my work, rather than the singular reading the rewriting and customization of the sources that a more formal paper would dictate. The footnotes, more informal in their structure than a conventional text, gave me the opportunity to more freely propose the plausible and temporal truths I am searching while escaping the traditional role of the author. The fragmented form of the paper also better reflected the conceptual aspects of my own practice, where the gaps of knowledge and unconnected dots inevitably are exposed just as openly as they are in this text.

Dialogue Through Design: Visual Communication Across The Cultural Divide

Publisher: name: Emily Carr University of Art and Design

Subjects: Communication--Design--Intercultural--Sustainability

description: This thesis describes how a designer pursued dialogue and collaboration in the design process when a shared verbal language or assumed technologies were not present. From June 2008 to February 2009, a two-phase project explored the role of communication design in a rural community in Africa. It considered how principles of governance could be applied to create a more transparent dialogue during the design process and investigated the impact of a designer's presence and absence in this context. During the project, a field bag was designed to act as a writing surface for ten women in Rwanda to use while participating in creative activities during the rituals of daily life. The activities were developed to help a designer have a visual conversation when working with individuals who do not share the same language, in order to discover the needs, assets, beliefs and desires of an individual or group before offering a design solution. By introducing a design methodology into a development context, adaptive tools were created to increase the opportunity for appropriate and effective outcomes. By focusing greater attention on the unspoken needs of the underserved, the often overlooked potential of their ideas can be revealed and accessed for future innovations. From here, design positions itself as a discipline that embraces ambiguity in the midst of complexity when seeking to address significant problems in a sustainable fashion.

description: The equation of state calculated by Saumon and collaborators has been adopted in most core-accretion simulations of giant-planet formation performed to date. Since some minor errors have been found in their original paper, we present revised simulations of giant-planet formation that considers a corrected equation of state. We employ the same code as Fortier and collaborators in repeating our previous simulations of the formation of Jupiter. Although the general conclusions of Fortier and collaborators remain valid, we obtain significantly lower core masses and shorter formation times in all cases considered. The minor errors in the previously published equation of state have been shown to affect directly the adiabatic gradient and the specific heat, causing an overestimation of both the core masses and formation times.

Holey Roket: Eco-centric Vernacular Design

Subjects: Cooking--Ecology--Design--Industrial Design--Sustainability

description: Holey Roket is a cooking stove type designed to improve existing cooking systems. Recognizing that more than fifty communities in Africa, South America and Asia use briquettes as a primary cooking fuel, this design project seeks to help improve local cooking solutions. Designed to use the biomass briquettes similar to those available in rural communities around the world, Holey Roket was developed in collaboration with Legacy Foundation, an Oregon-based NGO advocating alternative fuel technology. Designed for biomass briquettes, Holey Roket aims to dramatically reduce fuel consumption and harmful emissions. Borrowing from existing stove technologies and working in collaboration with local entrepreneurs, this design typology and social network has evolved as the fabrication of briquettes improves and knowledge about this alternative fuel is shared. Holey Roket is based on the understanding that, together with stove design and briquette fabrication, information sharing is necessary to help create better cooking systems. Holey Roket designs are currently being tested in four international contexts: DR Congo, Chad, Uganda, and Cambodia. Existing briquette manufacturing enterprises in each place represent different sets of socio-cultural relations and demand an adaptable consultant-design methodology capable of working with different materials, briquette recipes, gastronomic cultures, and social structures. Holey Roket represents a methodology designed to connect with local entrepreneurial networks and involves communicating information about stove technology and the adaptation of a Holey Roket typology across different contexts. This project is informed by the eco-centric concept of “ecosophy” developed in writings of Arne Naess and Felix Guattari. Ecosophy recognizes the philosophical milieu as a field of intrinsic social, economic, and cultural relations where one needs to find ways of partaking in non-anthropocentric collaboration. Extending ecosophy to a design context, Holey Roket looks at ‘vernacular’ building processes that unfold according to traditional, site-specific designs. Holey Roket engages with the virtual environment as a form of direct action. Accumulated information from various environments contributes to the single product-type data-base, and brings diverse local knowledge to a common table. Adaptations of Holey Roket show how experimentation gradually becomes tradition, and in the process, resilient, ever-more efficient cooking stove concepts are adapted to an increasing number of environments.

description: Let $\CC$ be a Hom-finite triangulated 2-Calabi-Yau category with a cluster-tilting object $T$. Under a constructibility condition we prove the existence of a set $\mathcal G^T(\CC)$ of generic values of the cluster character associated to $T$. If $\CC$ has a cluster structure in the sense of Buan-Iyama-Reiten-Scott, $\mathcal G^T(\CC)$ contains the set of cluster monomials of the corresponding cluster algebra. Moreover, these sets coincide if $\mathcal C$ has finitely many indecomposable objects. When $\CC$ is the cluster category of an acyclic quiver and $T$ is the canonical cluster-tilting object, this set coincides with the set of generic variables previously introduced by the author in the context of acyclic cluster algebras. In particular, it allows to construct $\Z$-linear bases in acyclic cluster algebras.

WATERMARKS: Resonant Absences in Painting and Memory

Subjects: Autobiography--Memory--Storytelling

description: This paper is about memory and about narrative, both of which are concerned with what is missing. It explores the ways that the events in our individual lives, our collective lives, become history and narrative. The paper considers writer Thomas King’s work on narrative, and Walter Benjamin’s work on memory as theatre. Many of the stories included here are personal. They might have been heard at kitchen tables, or on the phone from family and friends. Some stories are ones which I can’t recall not knowing. The paper poses questions such as how these things become important to our present. Whether and why it is important to remember, and what constitutes authenticity in memory. The narrative structure of the paper reflects these concerns, by highlighting spaces and absences. To an extent the structure manifested itself organically, as a result of attempts to provide an honest articulation of the questions and ideas which have impacted on my material practice. This has proven to be a delicate task, as it attempts to speak to a material practice that is ongoing, constantly changing. There are overlaps in the form and content of each but there is also a space in between. My modus operandi resists full disclosure. I have this image of myself, like I am in the backyard, in the dirt, excavating some things burying others. From a certain vantage point all you see is the upturned soil following me, dirt under my nails.

description: By calculating the change of entropy, we prove that the first law of black hole thermodynamics leads to the tunneling probability of massive particles through the horizon, including the tunneling probability of massive charged particles from the Reissner-Nordström black hole and the Kerr-Newman black hole. Novelly, we find the trajectories of massive particles are close to that of massless particles near the horizon, although the trajectories of massive charged particles may be affected by electromagnetic forces. We show that Hawking radiation as massive particles tunneling does not lead to violation of the weak cosmic-censorship conjecture.

Subjects: Autobiography--Documentary films--Disability studies--Sociology of disability

description: This paper examines the development of my thesis documentary film, First Steps, which portrays my experiences with a progressive disability, and situates my work in relation to different theoretical approaches to the representation of disability in film. The normative western construction of disability derives from legal, scientific, and medical models that tend to focus on repairing the handicap or curing the underlying physiological illness. This model of representing disability figures prominently in mainstream American film, and I discuss a number of the prevailing cinematic stereotypes about disability to expose how film helps to shape social perceptions about disability. I will consider these dominant discourses alongside alternative humanistic and socio-political discussions found in critical disability studies to consider how both discourses produce expressive possibilities, but also have their own limitations. Working through these different theoretical approaches in relation to the history of American film, I will explain how my own documentary negotiates both models of disability in an effort to find a balance between them and produce an authentic narrative of how I have experienced the onset of multiple sclerosis.

description: Quantum Hall states that result from interaction induced lifting of the eight-fold degeneracy of the zeroth Landau level in bilayer graphene are considered. We show that at even filling factors electric charge is injected into the system in the form of charge $2e$ skyrmions. This is a rare example of binding of charges in a system with purely repulsive interactions. We calculate the skyrmion energy and size as a function of the Zeeman interaction, and discuss signatures of the charge $2e$ skyrmions in the scanning tunneling microscopy experiments.

Multimedia Ritual Performance: Dialogues Between Cinema and Korean Shamanism

Subjects: Experimental films--Performance art--Multimedia (Art)--Digital storytelling

description: “Mu-dang's Cinematic Shrine” is a multimedia installation that is the result of a convergence of two different methodologies and explorations: cinema and Muism - Korean shamanism. This convergence makes apparent the recent divergence of forms and themes in my art practice since beginning my MAA Program. My thesis essay investigates three main concepts: 1. how medium and message are integrated to evoke a sense of numinosity and the liminality associated with the life-death continuum; 2. what my role is, as an artist, in creating a transformative space and language; and 3. how the space and form of my cinematic installation enhances audience interactivity, vis-à-vis the conventional cinematic apparatus. For this inquiry, I juxtapose the role of an artist to that of a Korean shaman, a mu-dang. My role as a media artist mimics a mu-dang’s spiritual role and ability: the channeling and creation of perceptual transformation and the facilitating of alternative storytelling. This idea and practice is informed by the experimental and sociopolitical cinema of Trinh T. Minh-ha and the experimental multi-media installation, performance, and theories of Theresa Hak Kyung Cha. Their theoretical investigations and writing on time, space, memory, identity, and language have influenced and inspired my own critical thinking and media production. This thesis essay intertwines their practice and theory with my own art practice in a ritualistic multi-media exploration.

description: As a designer, I have been identified as problem-solver, and rarely as prob­lem-identifier. Designers have the opportunity to make a significant differ­ence in society, and help in the development of conscious citizens from a wide range of cultures and languages. Intercultural interaction has increased within this globalized community, and it has become part of our lives. As a foreign communication designer, I have identified the importance of intercultural understanding, so we don’t alienate each other, and help develop shared experiences and collaborative projects when the same language, time and/or space may not be shared. This research study promotes the exploration of the process of a designer becoming a researcher and a thinker who collaborates within a multicultur­al community. It is an extended exploration of my previous experience col­laborating for Mátika Magazine within an international group of designers, visual artists and writers. Therefore, it explores the different possibilities that hybrid design brings to a stream of creative disciplines, and how this diversity can be used as a tool to expand the relationship between space, culture and creativity. Within this paper, I describe the process and outcomes of developing the project Inlak’esh Alaken. This project took form with an event hosted at the same time in three different cities: Vancouver, Guadalajara and Los Angeles. By pushing further the possibilities of online network services, a live video of each event was streamed online and projected in each place. Within this project, I practice the research of different technologies to create urban art as an exploration of new ways to communicate between different cultures. Therefore, every participant in each city shared the same performance with the use of Graffiti Wall and Laser Tag. With the use of these tools of non-verbal communication, the participants were asked to interact with the others and communicate at the same time in different places. Within this research and the process of my work, I aim to push the bound­aries of traditional communication design, and share a body of knowledge that might help other communication designers in the process of becoming researchers and agents of social change. I share the process of becom­ing a visual journalist, and how we as designers can develop a method of documentation that accounts for the moods and concerns of our society, bridging different environments and translating the outcomes into seduc­tive graphics of information.

description: We investigate bi-Hamiltonian structures and mKdV hierarchies of solitonic equations generated by (semi) Riemannian metrics and curve flows of non-stretching curves. There are applied methods of the geometry of nonholonomic manifolds enabled with metric-induced nonlinear connection (N-connection) structure. On spacetime manifolds, we consider a nonholonomic splitting of dimensions and define a new class of liner connections which are 'N-adapted', metric compatible and uniquely defined by the metric structure. We prove that for such a linear connection, one yields couples of generalized sine-Gordon equations when the corresponding geometric curve flows result in solitonic hierarchies described in explicit form by nonholonomic wave map equations and mKdV analogs of the Schrodinger map equation. All geometric constructions can be re-defined for the Levi-Civita connection but with "noholonomic mixing" of solitonic interactions. Finally, we speculate why certain methods and results from the geometry of nonholonmic manifolds and solitonic equations have general importance in various directions of modern mathematics, geometric mechanics, fundamental theories in physics and applications, and briefly analyze possible nonlinear wave configurations for modeling gravitational interactions by effective continuous media effects.

description: This thesis links disparate sources to build a new way of looking at abstract painting. It draws on anthropology, cognitive science, philosophy, and art history to open up a different discourse about abstraction. Alfred Gell’s anthropological theory of art is used as a model for investigating the various social exchanges that take place in the entire spectrum of interactions that abstract painting involves. These social transactions include both traditional linguistic ones, as well as non-linguistic exchanges. Cognitive science is looked at to investigate the experience of sensation at a more granular level than that of language. Philosophy, particularly of Gilles Deleuze, is discussed in order to tie sensation with the opening of a fissure to connect to new ways of thinking and debating. Art History is investigated to situate my own practice with other painters, both historical and contemporary. This openness of sources in my writing is reflective of the openness of the types of resources that I use in my painting practice, where I mix ornamentation, topology, and gesture. In both the written thesis and my art practice the goal is to regard abstraction as a means to facilitate alternative knowledge production. In this sense, abstraction is investigated as a search for discursiveness through a material practice.

description: We report on high-field magnetization measurements for a number of layered vanadium phosphates that were recently recognized as spin-1/2 frustrated square lattice compounds with ferromagnetic nearest-neighbor couplings (J_1) and antiferromagnetic next-nearest-neighbor couplings (J_2). The saturation fields of the materials lie in the range from 4 to 24 T and show excellent agreement with the previous estimates of the exchange couplings deduced from low-field thermodynamic measurements. The consistency of the high-field data with the regular frustrated square lattice model provides experimental evidence for a weak impact of spatial anisotropy on the nearest-neighbor couplings in layered vanadium phosphates. The variation of the J_2/J_1 ratio within the compound family facilitates the experimental access to the evolution of the magnetization curve upon the change of the frustration magnitude. Our results support the recent theoretical prediction by Thalmeier et al. [Phys. Rev. B, 77, 104441 (2008)] and give evidence for the enhanced bending of the magnetization curves due to the increasing frustration of the underlying spin system.

description: Cuticle-degrading serine protease Ver112, which derived from a nematophagous fungus Lecanicillium psalliotae, has been exhibited to have high cuticle-degrading and nematicidal activities. We have performed molecular dynamics (MD) simulation based on the crystal structure of Ver112 to investigate its dynamic properties and large-scale concerted motions. The results indicate that the structural core of Ver112 shows a small fluctuation amplitude, whereas the substrate binding sites, and the regions close to and opposite the substrate binding sites experience significant conformational fluctuations. The large concerted motions obtained from essential dynamics (ED) analysis of MD trajectory can lead to open or close of the substrate binding sites, which are proposed to be linked to the functional properties of Ver112, such as substrate binding, orientation, catalytic, and release. The significant motion in the loop regions that is located opposite the binding sites are considered to play an important role in modulating the dynamics of the substrate binding sites. Furthermore, the bottom of free energy landscape (FEL) of Ver112 are rugged, which is mainly caused by the fluctuations of substrate binding regions and loops located opposite the binding site. In addition, the mechanism underlying the high flexibility and catalytic activity of Ver112 was also discussed. Our simulation study complements the biochemical and structural studies, and provides insight into the dynamics-function relationship of cuticle-degrading serine protease Ver112.

description: We introduce the notion of Artin motives and cohomological motives over a scheme X. Given a cohomological motive M over X, we construct its punctual weight zero part $ω^0_X(M)$ as the universal Artin motive mapping to M. We use this to define a motive E_X over X which is an invariant of the singularities of X. The first half of the paper is devoted to the study of the functors $ω^0_X$ and the computation of the motives E_X. In the second half of the paper, we develop the application to locally symmetric varieties. Specifically, let Y be a locally symmetric variety and denote by p:W-->Z the projection of its reductive Borel-Serre compactification W onto its Baily-Borel Satake compactification Z. We show that $Rp_*(\Q_W)$ is naturally isomorphic to the Betti realization of the motive E_Z, where Z is viewed as a scheme. In particular, the direct image of E_Z along the projection of Z to Spec(C) gives a motive whose Betti realization is naturally isomorphic to the cohomology of W.

description: We study a unique proto-cluster of galaxies, the supergroup SG1120-1202. We quantify the degree to which morphological transformation of cluster galaxies occurs prior to cluster assembly in order to explain the observed early-type fractions in galaxy clusters at z=0. SG1120-1202 at z~0.37 is comprised of four gravitationally bound groups that are expected to coalesce into a single cluster by z=0. Using HST ACS observations, we compare the morphological fractions of the supergroup galaxies to those found in a range of environments. We find that the morphological fractions of early-type galaxies (~60 %) and the ratio of S0 to elliptical galaxies (0.5) in SG1120-1202 are very similar to clusters at comparable redshift, consistent with pre-processing in the group environment playing the dominant role in establishing the observed early-type fraction in galaxy clusters.

description: We present an experimental and theoretical study of the conductance and stability of Mg atomic-sized contacts. Using Mechanically Controllable Break Junctions (MCBJ), we have observed that the room temperature conductance histograms exhibit a series of peaks, which suggests the existence of a shell effect. Its periodicity, however, cannot be simply explained in terms of either an atomic or electronic shell effect. We have also found that at room temperature, contacts of the diameter of a single atom are absent. A possible interpretation could be the occurrence of a metal-to-insulator transition as the contact radius is reduced, in analogy with what it is known in the context of Mg clusters. However, our first principle calculations show that while an infinite linear chain can be insulating, Mg wires with larger atomic coordinations, as in realistic atomic contacts, are alwaysmetallic. Finally, at liquid helium temperature our measurements show that the conductance histogram is dominated by a pronounced peak at the quantum of conductance. This is in good agreement with our calculations based on a tight-binding model that indicate that the conductance of a Mg one-atom contact is dominated by a single fully open conduction channel.

description: The abundant $ψ'$ events have been collected at the Beijing Electron Positron Collider-II (BEPCII) that could undoubtedly provide us with a great opportunity to study the more attractive charmonium decays. As has been noticed before, in the process of $J/ψ$ decaying to the baryonic final states, $p K^- \barΛ$, the evident $Λ^*$ and $N^*$ bands have been observed. Similarly, by using the product of $χ_{cJ}$ from $ψ'$ radiative decay, we may confirm it or find some extra new resonances. $χ_{c0}$'s data samples will be more than $χ_{c1,2}$ taking into account the larger branching ratio of $ψ'\toγχ_{c0}$. Here, we provide explicit partial wave analysis formulae for the very interesting channel $ψ'\toγχ_{c0}\to γp K^- \barΛ$.

description: The relationship between point vortex dynamics and the properties of polynomials with roots at the vortex positions is discussed. Classical polynomials, such as the Hermite polynomials, have roots that describe the equilibria of identical vortices on the line. Stationary and uniformly translating vortex configurations with vortices of the same strength but positive or negative orientation are given by the zeros of the Adler-Moser polynomials, which arise in the description of rational solutions of the Korteweg-de Vries equation. For quadupole background flow, vortex configurations are given by the zeros of polynomials expressed as wronskians of Hermite polynomials. Further new solutions are found in this case using the special polynomials arising the in the description of rational solutions of the fourth Painleve equation.

GALEX ultraviolet observations of stellar variability in the Hyades and Pleiades clusters

description: We present GALEX near ultraviolet (NUV:1750 - 2750A) and far ultraviolet (FUV: 1350 - 1750A) imaging observations of two 1.2 degree diameter fields in the Hyades and Pleiades open clusters in order to detect possible UV variability of the member stars. We have performed a detailed software search for short-term UV flux variability during these observations of the approx 400 sources detected in each of the Hyades and Pleiades fields to identify flare-like (dMe) stellar objects. This search resulted in the detection of 16 UV variable sources, of which 13 can be directly associated with probable M-type stars. The other UV sources are G-type stars and one newly discovered RR Lyrae star, USNOB1.0 1069-0046050, of period 0.624 day and distance 4.5-7.0 kpc. Light curves of photon flux versus time are shown for 7 flare events recorded on six probable dMe stars. UV energies for these flares span the range 2E27 to 5E29 erg, with a corresponding NUV variability change of 1.82 mag. Only one of these flare events (on the star Cl* Melotte 25 LH129) can definitely be associated with an origin on a member the Hyades cluster itself. Finally, many of our M-type candidates show long periods of enhanced UV activity but without the associated rapid increase in flux that is normally associated with a flare event. However, the total UV energy output during such periods of increased activity is greater than that of many short-term UV flares. These intervals of enhanced low-level UV activity concur with the idea that, even in quiescence, the UV emission from dMe stars may be related to a superposition of many small flare events possessing a wide range of energies.

Dark Matter in the Galaxy Cluster CL J1226+3332 at Z=0.89

description: We present a weak-lensing analysis of the galaxy cluster CL J1226+3332 at z=0.89 using Hubble Space Telescope Advanced Camera for Surveys images. The cluster is the hottest (>10 keV), most X-ray luminous system at z>0.6 known to date. The relaxed X-ray morphology, as well as its high temperature, is unusual at such a high redshift. Our mass reconstruction shows that on a large scale the dark matter distribution is consistent with a relaxed system with no significant substructures. However, on a small scale the cluster core is resolved into two mass clumps highly correlated with the cluster galaxy distribution. The dominant mass clump lies close to the brightest cluster galaxy whereas the other less massive clump is located ~40" (~310 kpc) to the southwest. Although this secondary mass clump does not show an excess in the X-ray surface brightness, the gas temperature of the region is much higher (12~18 keV) than those of the rest. We propose a scenario in which the less massive system has already passed through the main cluster and the X-ray gas has been stripped during this passage. The elongation of the X-ray peak toward the southwestern mass clump is also supportive of this possibility. We measure significant tangential shears out to the field boundary (~1.5 Mpc), which are well described by an Navarro-Frenk-White profile with a concentration parameter of c200=2.7+-0.3 and a scale length of rs=78"+-19" (~600 kpc) with chi^2/d.o.f=1.11. Within the spherical volume r200=1.6 Mpc, the total mass of the cluster becomes M(r0.6.

description: The Gaudin model based on the sl_2-invariant r-matrix with an extra Jordanian term depending on the spectral parameters is considered. The appropriate creation operators defining the Bethe states of the system are constructed through a recurrence relation. The commutation relations between the generating function t(λ) of the integrals of motion and the creation operators are calculated and therefore the algebraic Bethe Ansatz is fully implemented. The energy spectrum as well as the corresponding Bethe equations of the system coincide with the ones of the sl_2-invariant Gaudin model. As opposed to the sl_2-invariant case, the operator t(λ) and the Gaudin Hamiltonians are not hermitian. Finally, the inner products and norms of the Bethe states are studied.

Current-induced microwave excitation of a domain wall confined in a magnetic wire with bi-axial anisotropy

description: We studied the current-induced magnetization dynamics of a domain wall confined in a magnetic wire with bi-axial anisotropy. We showed that above the threshold current density, breathing-mode excitation, where the thickness of the domain wall oscillates, is induced by spin-transfer torque. We found that the breathing-mode can be applied as a source of microwave oscillation because the resistance of the domain wall is a function of the domain wall thickness. In a current sweep simulation, the frequency of the breathing-mode exhibits hysteresis because of the confinement.

description: We consider the optimal positioning of an even number of crew members in a coxless racing boat in order to avoid the presence of a sideways wiggle as the boat is propelled forwards through the water. We show that the traditional (alternate port and starboard) rig of racing boats always possesses an oscillating non-zero transverse moment and associated wiggling motion. We show that the problem of finding the zero-moment rigs is related to a special case of the Subset Sum problem. We find the one (known) zero-moment rig for a racing Four and show there are four possible such rigs for a racing Eight, of which only two (the so called 'Italian' and 'German' rigs) appear to be already known. We also give the 29 zero-moment solutions for racing Twelves but refrain from explicitly listing the 263 Sixteens and 2724 Twenties which have zero transverse moments. We show that only balanced boats with crew numbers that are divisible by four can have the zero-moment property. We also discuss some aspects of unbalanced boats, in which the number of port and starboard oars are unequal.

description: We present an algorithm running in time O(n ln n) which decides if a wreath-closed permutation class Av(B) given by its finite basis B contains a finite number of simple permutations. The method we use is based on an article of Brignall, Ruskuc and Vatter which presents a decision procedure (of high complexity) for solving this question, without the assumption that Av(B) is wreath-closed. Using combinatorial, algorithmic and language theoretic arguments together with one of our previous results on pin-permutations, we are able to transform the problem into a co-finiteness problem in a complete deterministic automaton.
