Preserving Postmodern Architecture and the Legacy of Charles W. Moore
Creators: Ryan, Kaitlin E.

Subjects: subject: Architecture
subject: FOS: Civil engineering

description: Charles Moore is central to understanding the continuum extant between Modern and Postmodern architecture. This is not simply because he practiced architecture from the mid-1950s through 1993, spanning the time period between these two styles; it is also because his architecture, writing and teaching bridged the practical and theoretical tenets of both movements. Moore maintains a unique position among his contemporaries in that he was both a modernist and postmodernist in many ways. Deeply influenced by modernists William Wurster and Louis Kahn, Moore also drew upon Roger Bailey's appreciation for history and the Beaux Arts curriculum as well as Jean Labatut's phenomenological emphasis on human experience of historical places. The design-build mentality that Moore adopted from Roger Bailey and William Wurster along with the purity of form derived from Louis Kahn's teaching, reflect the inherently modern qualities of his designs. His explorations with interior and exterior space, color, light and creating a "sense of place" represent the postmodern innovations that Moore brought to the field. He was an inclusivist, which signifies a departure from his predecessors and an approach that greatly shaped his lasting influence. This research seeks to answer how Moore's role in the context of the late twentieth century is central to understanding the significance that his work, writing and pedagogical influence had on contemporaries and students alike. And furthermore, can that understanding inform the way in which his work can be approached in the preservation context? To that end, this thesis presents Moore's biographical background and contextual history along with a discussion of three commissions that were central to his body of work: Kresge College (1973) at the University of California, Santa Cruz; the Piazza d'Italia (1978) in New Orleans, Louisiana; and the Moore/Andersson Compound (1984) in Austin, Texas. The temporal and ephemeral qualities inherent in much of Moore's work were characteristic of the time period and paralleled in the work of other architects practicing at the time, most notably Robert Venturi. These qualities pose unique challenges to preservation from a theoretical and practical perspective. This research presents a lens through which those challenges and opportunities can be understood and further explored. Moore's influence is evident in the work of many of his students, a great number of whom are successful in their own right, including Billie Tsien, Brian Mackay-Lyons, and Turner Brooks. His lasting impact is also apparent in the ongoing success of his former firms: Centerbrook Architects in Centerbrook, Connecticut; Moore Ruble Yudell in Santa Monica, California; and Andersson/Wise Architects in Austin, Texas. These firms continue to thrive twenty years after Moore's death, reiterating the continued influence that Charles Moore has had on architectural practice and teaching.

description: We study the growth of aligned domains in nematic liquid crystals. Results are obtained solving the Beris-Edwards equations of motion using the lattice Boltzmann approach. Spatial anisotropy in the domain growth is shown to be a consequence of the flow induced by the changing order parameter field (backflow). The generalization of the results to the growth of a cylindrical domain, which involves the dynamics of a defect ring, is discussed.

description: In the last two decades, theories explaining the same experiments as well as special relativity does, were developed by using different synchronization procedures. All of them are ether-like theories. Most authors believe these theories to be equivalent to special relativity, but no general proof was ever brought. By means of a Gedankenexperiment on light aberration, we produce strong evidence that this is the case for experiments made in inertial systems.

description: We present a numerical study of the time evolution of perturbations of rotating black holes. The solutions are obtained by integrating the Teukolsky equation written as a first-order in time, coupled system of equations, in a form that explicitly captures its hyperbolic structure. We address the numerical difficulties of solving the equation in its original form. We follow the propagation of generic initial data through the burst, quasinormal ringing and power-law tail phases. In particular, we calculate the effects due to the rotation of the black hole on the scattering of incident gravitational wave pulses. These results may help explain how the angular momentum of the black hole affects the gravitational waves that are generated during the final stages of black hole coalescence.

Mural painting and decoration--Conservation and restoration

description: The contemporary community mural movement has played a critical role in allowing residents of cities to reflect upon particular historic, cultural or political climates publicly, and can be traced back to the 1967 mural Wall of Respect, painted along a Southside Chicago building to advocate for the grassroots civil rights movement.  As noted by Chilean poet Pablo Neruda, "murals are the people's blackboards", through which they are able to beautify, educate, celebrate, protest and motivate their communities to action. However, despite the powerful role the murals have played in communities, many are deteriorating or face demolition for a variety of reasons, from a deteriorating wall on which they are painted, lack of basic maintenance, shifting demographics within the community that render the mural irrelevant, and evolving aesthetic tastes. With the loss of community murals, neighborhoods are at risk of losing not only their public art, but also the often-contentious history that caused their creation. This thesis aims to address the preservation of community murals in Harlem and East Harlem in New York City. Through a study of the changing demographics of the study area and the role that community murals have played, documentation of the existing community murals, and the role that they have played in giving minority communities a public voice, this thesis will take a critical approach to the policy void that exists in New York City and how non-profit public art programs have advocated and can advocate for our city's murals continued existence.
Towards closure of the Fire Road Ard site in New Brunswick

Year: 2014

description: The approximately 120 ha backfilled Fire Road coal mine cut, located near Fredericton New Brunswick, has been a source of acid rock drainage since the mid 1980’s. Lime neutralization treatment of drainage has been continuously ongoing. The cut, with depths to approximately 20 m, is located in sandstones containing iron sulphides, principally pyrite, in the range of 1 to 2 wt%. Site water chemistry has been intensively monitored over the years using a series of groundwater wells within and bordering the disturbed areas. This has provided a considerable inventory of water chemistry data which has enabled interpretation of the characteristics of acid generation at the site; the effectiveness of “in situ” neutralization in reducing the ultimate acidity of the drainage, and trends in acidity over the years. During the past number of years a definite trend of decreasing acidity has been observed leading to the conclusion that the site should exhibit “zero lime demand” within the next 10 years. At present, plans are being developed for final closure of the site.
Preserving North Carolina's Last Textile Landscape: The Case for Henry River Mill Village
Creators: Carroll, Kelly Autumn
Publisher: name: Columbia University
Year: 2012
Subjects: subject: Architecture
subject: FOS: Civil engineering

description: This paper investigates the history and architecture of the functionally obsolete and abandoned Henry River Mill Village and offers a preservation strategy for the site. This thesis contributes to the historical narrative of the textile industry and the landscapes that emerged from this industry in the state of North Carolina between 1880 and 1915. Based on research via primary and secondary sources, a site visit, interviews with historians, planners, non-profits and local and state leaders over a year-long period, it became apparent that traditional preservation strategies for Henry River were not appropriate and/or viable options. The preservation strategy offered is for the site to function as a cultural resource set in a public park, with the extant and ruinous architecture stabilized and interpreted, with the exception of the company store which should be rehabilitated and renovated. The site will function as a connector to the region and state's greenway and blueway corridors. To conclude, preservation in this form, as a "ghost town," represents the state's textile heritage in the purest form because its ruinous state does not conceal the post-industrial condition of the departed textile industry. Refurbished historic sites are not realistic representations of the condition of the recent past. Henry River Mill Village could serve as the first and only representation of an intact, post-industrial textile landscape in North Carolina.

description: Although there exists a large sample of known exoplanets, little spectroscopic data exists that can be used to study their global atmospheric properties. This deficiency can be addressed by performing phase-resolved spectroscopy -- continuous spectroscopic observations of a planet's entire orbit about its host star -- of transiting exoplanets. Planets with characteristics suitable for atmospheric characterization have orbits of several days, thus phase curve observations are highly resource intensive, especially for shared use facilities. In this work, we show that an infrared spectrograph operating from a high altitude balloon platform can perform phase-resolved spectroscopy of hot Jupiter-type exoplanets with performance comparable to a space-based telescope. Using the EXoplanet Climate Infrared TElescope (EXCITE) experiment as an example, we quantify the impact of the most important systematic effects that we expect to encounter from a balloon platform. We show an instrument like EXCITE will have the stability and sensitivity to significantly advance our understanding of exoplanet atmospheres. Such an instrument will both complement and serve as a critical bridge between current and future space-based near infrared spectroscopic instruments.

description: We show that the reality conditions to be imposed on Ashtekar variables to recover real gravity can be implemented as second class constraints a la Dirac. Thus, counting gravitational degrees of freedom follows accordingly. Some constraints of the real theory turn out to be non-polynomial, regardless of the form, polynomial or non-polynomial, taken for the reality conditions. We comment upon the compatibility of our approach with the recently proposed Wick transform point of view, as well as on some alternatives for dealing with such second class constraints.

description: We investigate the interplay between the high- and low-energy phenomenology of $C\!P$-violating interactions of the Higgs boson with gauge bosons. For this purpose we use an effective field theory approach and consider all dimension-6 operators arising in so-called universal theories. We compute their loop-induced contributions to electric dipole moments and the $C\!P$ asymmetry in $B\to X_sγ$, and compare the resulting current and prospective constraints to the projected sensitivity of the LHC. Low-energy measurements are shown to generally have a far stronger constraining power, which results in highly correlated allowed regions in coupling space, a distinctive pattern that could be probed at the high-luminosity LHC.

Year: 1997
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The ``warp drive'' metric recently presented by Alcubierre has the problem that an observer at the center of the warp bubble is causally separated from the outer edge of the bubble wall. Hence such an observer can neither create a warp bubble on demand nor control one once it has been created. In addition, such a bubble requires negative energy densities. One might hope that elimination of the first problem might ameliorate the second as well. We analyze and generalize a metric, originally proposed by Krasnikov for two spacetime dimensions, which does not suffer from the first difficulty. As a consequence, the Krasnikov metric has the interesting property that although the time for a one-way trip to a distant star cannot be shortened, the time for a round trip, as measured by clocks on Earth, can be made arbitrarily short. In our four dimensional extension of this metric, a ``tube'' is constructed along the path of an outbound spaceship, which connects the Earth and the star. Inside the tube spacetime is flat, but the light cones are opened out so as to allow superluminal travel in one direction. We show that, although a single Krasnikov tube does not involve closed timelike curves, a time machine can be constructed with a system of two non-overlapping tubes. Furthermore, it is demonstrated that Krasnikov tubes, like warp bubbles and traversable wormholes, also involve unphysically thin layers of negative energy density, as well as large total negative energies, and therefore probably cannot be realized in practice.

description: We offer an example of an network model with a power law degree distribution, P(k) ~ k^{-alpha}, for nodes but which nevertheless has a well-defined geography and a nonzero threshold percolation probability for alpha>2, the range of real-world contact networks. This is different from the p_c=0 for alpha<3 results for well-mixed scale-free networks. In our lattice-based scale-free network, individuals link to nearby neighbors on a lattice. Even considerable additional small-world links do not change our conclusion of nonzero thresholds. When applied to disease propagation, these results suggest that random immunization may be more successful in controlling human epidemics than previously suggested if there is geographical clustering.

Due to the specific form of the profile it is possible to extend the group of normal-form-preserving diffeomorphisms to include non-smooth transformations. This extension entails a richer structure of the symmetry algebra generated by the (non-smooth) Killing vectors.

description: Since coming to power in 2010, the Conservative Party in the UK has been pursuing increasingly harsh policies tackling undocumented migration that have come to be collectively known as the ‘hostile environment.’ These policies seek to make life difficult for anyone living in the UK without regular status, by requiring documentation checks when accessing services such as healthcare, housing, employment, and so forth. The stated goal of the policies is both to encourage undocumented migrants present in the UK to leave, and to deter potential migrants from entering in the first place. By examining the manner in which such policies were designed and implemented, and critiquing the degree to which they were executed in a well-planned and methodical way, this thesis seeks to question the extent to which migrants themselves were the target audience of the hostile environment. It instead suggests that the hostile environment is an example of ‘symbolic policy’, with the primary aim being to appeal to domestic voters.

description: This work presents a large-scale, longitudinal measurement study on the adoption of application updates, enabling continuous reporting of potentially vulnerable software populations worldwide. Studying the factors impacting software currentness, we investigate and discuss the impact of the platform and its updating strategies on software currentness, device lock-in effects, as well as user behavior. Utilizing HTTP User-Agent strings from end-hosts, we introduce techniques to extract application and operating system information from myriad structures, infer version release dates of applications, and measure population adoption, at a global scale. To deal with loosely structured User-Agent data, we develop a semi-supervised method that can reliably extract application and version information for some 87% of requests served by a major CDN every day. Using this methodology, we track release and adoption dynamics of some 35,000 applications. Analyzing over three years of CDN logs, we show that vendors' update strategies and platforms have a significant effect on the adoption of application updates. Our results show that, on some platforms, up to 25% of requests originate from hosts running application versions that are out-of-date by more than 100 days, and 16% more than 300 days. We find pronounced differences across geographical regions, and overall, less developed regions are more likely to have out-of-date software versions. Though, for every country, we find that at least 10% of requests reaching the CDN run software that is out-of-date by more than three months.

description: We investigate the computational requirements for all-sky, all-frequency searches for gravitational waves from spinning neutron stars, using archived data from interferometric gravitational wave detectors such as LIGO. These sources are expected to be weak, so the optimal strategy involves coherent accumulaton of signal-to-noise using Fourier transforms of long stretches of data (months to years). Earth-motion-induced Doppler shifts, and intrinsic pulsar spindown, will reduce the narrow-band signal-to-noise by spreading power across many frequency bins; therefore, it is necessary to correct for these effects before performing the Fourier transform. The corrections can be implemented by a parametrized model, in which one does a search over a discrete set of parameter values. We define a metric on this parameter space, which can be used to determine the optimal spacing between points in a search; the metric is used to compute the number of independent parameter-space points Np that must be searched, as a function of observation time T. The number Np(T) depends on the maximum gravitational wave frequency and the minimum spindown age tau=f/(df/dt) that the search can detect. The signal-to-noise ratio required, in order to have 99% confidence of a detection, also depends on Np(T). We find that for an all-sky, all-frequency search lasting T=10^7 s, this detection threshhold is at a level of 4 to 5 times h(3/yr), where h(3/yr) is the corresponding 99% confidence threshhold if one knows in advance the pulsar position and spin period.

description: Modern operating systems are often the target of attacks that exploit vulnerabilities to escalate their privilege level. Recently introduced hardening features prevent attackers from using traditional kernel exploitation methodologies and force them to employ techniques that were originally designed for user space exploitation —such as code reuse— to execute arbitrary code with elevated privileges. In this dissertation, we present novel protection mechanisms that render such methodologies ineffective and improve the security of today’s operating systems. Specifically, we present solutions that prevent the leakage and corruption of kernel code pointers without employing entities that execute on super-privileged mode (e.g., hypervisors). The leakage of code pointers is an essential step for the construction of reliable code reuse exploits and their corruption is typically necessary for mounting the attack. More concretely, we present the design and implementation of two systems: kR^X and kSplitStack. kR^X is a system that diversifies the code layout to thwart attackers from constructing code reuse exploits statically. It also prevents the leakage of return addresses through XOR- based encryption or by hiding them among decoys (fake pointers to instructions that trap the kernel when executed). Finally, it couples the above with a self-protection mechanism that prevents attackers from leaking the diversified code layout, either by instrumenting every memory read instruction with range checks on x86-64 systems or by imposing limits through the segmentation unit on x86 systems. Evaluation results show that it imposes small runtime overhead on real-world applications when measured on legacy x86-64 systems (~3.63%) and significantly lower on x86 systems (~1.32%) and newer x86-64 CPUs that provide hardware assistance (~2.32%). kSplitStack, on the other hand, provides stronger protection against leaks of return addresses and guarantees both their secrecy and their integrity by augmenting the isolation mechanism of kR^X on x86-64 systems. This is achieved through a split stack scheme: functions use an unprotected stack for their local variables but switch to a protected one when pushing or poping return addresses. Moreover, kSplitStack protects the secrecy and integrity of control data (e.g., the value of the instruction pointer) in interrupt contexts by redirecting them to protected stacks, thus thwarting attackers from leaking or corrupting code pointers by inducing interrupts or other hardware events. Finally, the evaluation of kSplitStack shows that it imposes a small runtime overhead, comparable to the one of kR^X, both on legacy x86-64 systems (~3.66%) and on newer CPUs with hardware assistance (~2.50%).

description: In the present work we examine the statics and dynamics of multiple parallel dark soliton stripes in a two-dimensional Bose-Einstein condensate. Our principal goal is to study the effect of the interaction between the stripes on the transverse instability of the individual stripes. We use a recently developed adiabatic invariant formulation to derive a quasi-analytical prediction for the stripe equilibrium position and for the Bogoliubov-de Gennes spectrum of excitations of stationary stripes. The cases of two-, three- and four-stripe states are studied in detail. We subsequently test our predictions against numerical simulations of the full two-dimensional Gross-Pitaevskii equation. We find that the number of unstable eigenmodes increases as the number of stripes increases due to (unstable) relative motions between the stripes. Their corresponding growth rates do not significantly change, although for large chemical potentials, the larger the stripe number, the larger the maximal instability growth rate. The instability induced dynamics of multiple stripe states and their decay into vortices are also investigated.

description: Since valid inferences from true premises to true conclusions are compatible with logically false premises or logically true conclusions, it is obviously necessary to exclude the latter from the former inferences. Is it possible to explain inferences to be valid if they do not involve this “paradox of formal implication”? For clarifying this question the concept of logical connectives (I) is revised, (II) is revealed by truth value relations, and (III) inferences are considered to be valid in terms of reflexive truth value relations.

description: First, we consider a fundamental pricing model for a single type of reusable resource in which a fixed number of units are used to serve stochastically arriving customers. Customers choose to purchase the resource based on their willingness-to-pay and the current price. If purchased, occupy one unit of the reusable resources for a random amount of time. The firm seeks to maximize a weighted combination of profit, market share, and service level. We establish a series of theoretical results that characterize the strong universal performance of static pricing in such an environment. Second, we describe a comprehensive approach to pricing analytics for reusable resources in the context of rotable spare parts with an industrial partner. We discuss the process of instilling a new pricing culture and developing a scalable new pricing methodology at a major aircraft manufacturer. We develop a novel pricing analytics approach for all rotable spare parts. The new approach tackles the challenges of limited data availability, minimal demand information, and complex inventory dynamics. We also present a successful large-scale implementation of our approach which led to significant profit gains. Third, we extend the pricing model for reusable resources to the setting of multiple customer classes. We describe two types of heuristics for this class of problem with accompanying numerical experiments. In addition, we provide a universal performance guarantee for a special case. We also discuss the role of substitution effects between different classes of customers.

description: Femtosecond laser excitation of a Co/Pt bilayer results in the efficient emission of picosecond THz pulses. Two known mechanisms for generating THz emission are spin-polarized currents through a Co/Pt interface, resulting in helicity-independent electric currents in the Pt layer due to the inverse spin-Hall effect and helicity-dependent electric currents at the Co/Pt interface due to the inverse spin-orbit torque effect. Here we explore how roughness, crystal structure and intermixing at the Co/Pt interface affect the efficiency of the THz emission. In particular, we varied the roughness of the interface, in the range of 0.1-0.4 nm, by tuning the deposition pressure conditions during the fabrication of the Co/Pt bilayers. To control the intermixing at the Co/Pt interface a 1-2 nm thick CoxPt1-x alloy spacer layer was introduced with various compositions of Co and Pt. Finally, the crystal structure of Co was varied from face centered cubic to hexagonal close packed. Our study shows that the roughness of the interface is of crucial importance for the efficiency of helicity-dependent THz emission induced by femtosecond laser pulses. However, it is puzzling that intermixing while strongly enhancing the helicity-independent THz emission had no effect on the helicity-dependent THz emission which is suppressed and similar to the smooth interfaces.

description: Many network operations, ranging from attack investigation and mitigation to traffic management, require answering network-wide flow queries in seconds. Although flow records are collected at each router, using available traffic capture utilities, querying the resulting datasets from hundreds of routers across sites and over time, remains a significant challenge due to the sheer traffic volume and distributed nature of flow records. In this paper, we investigate how to improve the response time for a priori unknown network-wide queries. We present Flowyager, a system that is built on top of existing traffic capture utilities. Flowyager generates and analyzes tree data structures, that we call Flowtrees, which are succinct summaries of the raw flow data available by capture utilities. Flowtrees are self-adjusted data structures that drastically reduce space and transfer requirements, by 75% to 95%, compared to raw flow records. Flowyager manages the storage and transfers of Flowtrees, supports Flowtree operators, and provides a structured query language for answering flow queries across sites and time periods. By deploying a Flowyager prototype at both a large Internet Exchange Point and a Tier-1 Internet Service Provider, we showcase its capabilities for networks with hundreds of router interfaces. Our results show that the query response time can be reduced by an order of magnitude when compared with alternative data analytics platforms. Thus, Flowyager enables interactive network-wide queries and offers unprecedented drill-down capabilities to, e.g., identify DDoS culprits, pinpoint the involved sites, and determine the length of the attack.
Conservative dynamics of binary systems to fourth Post-Newtonian order in the EFT approach II: Renormalized Lagrangian

description: We complete the derivation of the conservative dynamics of binary systems to fourth Post-Newtonian (4PN) order in the effective field theory (EFT) approach. We present a self-contained (ambiguity-free) computation of the renormalized Lagrangian, entirely within the confines of the PN expansion. While we confirm the final results reported in the literature, we clarify several issues regarding intermediate infrared (IR) and ultraviolet (UV) divergences, as well as the renormalization procedure. First, we properly identify the IR and UV singularities using (only) dimensional regularization and the method of regions, which are the pillars of the EFT formalism. This requires a careful study of scaleless integrals in the potential region, as well as conservative contributions from radiation modes due to tail effects. As expected by consistency, the UV divergences in the near region (due to the point-particle limit) can be absorbed into two counter-terms in the worldline effective theory. The counter-terms can then be removed by field redefinitions, such that the renormalization scheme-dependence has no physical effect to 4PN order. The remaining IR poles, which are spurious in nature, are unambiguously removed by implementing the zero-bin subtraction in the EFT approach. The procedure transforms the IR singularities into UV counter-parts. As anticipated, the left-over UV poles explicitly cancel out against UV divergences in conservative terms from radiation-reaction, uniquely determining the gravitational potential. Similar artificial IR/UV poles, which are intimately linked to the split into regions, are manifest at lower orders. Starting at 4PN, both local- and nonlocal-in-time contributions from the radiation region enter in the conservative dynamics. Neither additional regulators nor ambiguity-parameters are introduced at any stage of the computations.
