description: There is a growing trend toward quality-based specifications in highway construction. A large number of quality control/quality assurance (QC/QA) specifications shift the responsibility of day-to-day testing from the state DOH to the contractor. This requirement for contractor-performed quality control testing has been partly due to the fact that state agencies are operating with a smaller pool of employees compared to previous years. Another driving force has been the application of performance-based specifications and realization that the contractor and the producer need some degree of flexibility in order to be more efficient and innovative. This report presents the background information behind the development of the new QC/QA Concrete specifications in Kentucky. Findings of this study have already been implemented in the form of a Special Note for QC/QA Concrete, which is expected to be fully implemented by the year 2002. The QC/QA Special Note encourages the Contractor to produce a consistent quality product by giving incentives. Conversely, it penalizes the Contractor for poor quality, and/or inconsistent quality. The Special Note has been written with quality and innovation in mind. That is why it allows the Contractor and the Producer to follow the ACI-318 procedures for concrete mix design as well as the Kentucky Transportation Cabinet recipe mixes.

description: We study oscillons in D+1 space-time dimensions using a spherically symmetric ansatz. From Gaussian initial conditions, these evolve by emitting radiation, approaching ``quasi-breathers'', near-periodic solutions to the equations of motion. Using a truncated mode expansion, we numerically determine these quasi-breather solutions in 25 and the possibility of stable solutions for D<2.

title: Efficient and Effective Methodologies for Exploring and Prediction Movement Patterns in Large Networks

Publisher: name: University of Liverpool Repository
Year: 2018

description: In the era of Big Data the prevalence of networks of all kinds has grown dramatically, and analysing (mining) such networks to support decision-making processes has become an extremely important subject for research, typically with a view to some social and/or economic gain. This thesis describes research work within the theme of Movement Pattern Mining (MPM) as applied to large network data. MPM is a type of frequent pattern mining that provides observation into how information is exchanged between objects in large networks. In the context of the work described in this thesis, the focus is on how the concept of Movement Patterns (MPs) can be extracted from large networks efficiently and effectively, and how such movement patterns can best be utilised so as to predict future movement. The work describes how, by utilising big data facilities like Share/Distribute Memory Systems and Hadoop/MapReduce, novel data mining based techniques can be used, not only to extract MPs from large networks, but also how they can be utilised for prediction purposes. To this end, the works in this thesis are divided into two parts. The first part is concerned with an investigation of an efficient mechanism for MPM. The second part is concerned with the utilisation of the extracted MPs in the context of prediction. For evaluation purposes, two large network datasets were used: The Great Britain Cattle Tracking System database and the Jiayuan Social Network. The evaluation indicates that an efficient and effective mechanism for identifying and extracting MPs form large networks, and subsequently using then MPs for prediction purposes, has been established.

description: Galaxy mergers are central to our understanding of galaxy formation, especially within the context of hierarchical models. Besides having a large impact on the star formation history, mergers are also able to influence gas motions at the centre of galaxies and trigger an Active Galactic Nucleus (AGN). In this paper, we present a case study of the Seyfert galaxy NGC 2992, which together with NGC 2993 forms the early-stage merger system Arp 245. Using Gemini Multi-Object Spectrograph (GMOS) integral field unit (IFU) data from the inner 1.1 kpc of the galaxy we were able to spatially resolve the stellar populations, the ionisation mechanism and kinematics of ionised gas. From full spectral synthesis, we found that the stellar population is primarily composed by old metal-rich stars (t $\geq$ 1.4 Gyr, $Z \geq 2.0$\zsun), with a contribution of at most 30 per cent of the light from a young and metal-poor population (t $\leq$ 100 Myr, $Z \leq 1.0$\zsun). We detect \halpha and \hbeta emission from the Broad Line Region (BLR) with a Full Width at Half Maximum (FWHM) of $\sim$ 2000\kms. The Narrow Line Region (NLR) kinematics presents two main components: one from gas orbiting the galaxy disk and a blueshifted (velocity $\approx$ -200\kms) outflow, possibly correlated with the radio emission, with mass outflow rate of $\sim$ 2 M$_{\odot}$ yr$^{-1}$ and a kinematic power of $\sim$ 2 $\times 10^{40}$ erg s$^{-1}$ (\Eout/\Lbol $\approx$ 0.2 per cent). We also show even though the main ionisation mechanism is the AGN radiation, ionisation by young stars and shocks may also contribute to the emission line ratios presented in the innermost region of the galaxy.

description: Development of a comprehensive geotechnical database for risk management of highway rock slope problems is described. Computer software selected to program the client/server application in windows’ environment, components and structure of the geotechnical database, and some of the primary factors considered in constructing the database are discussed. In the establishment of a large database that will be used widely, it is extremely important to select development software that will allow simultaneous use of the database by numerous users. Major integrated components of the database include rock slope, landslide, and soil and rock engineering data. This report mainly focuses on the rock slope component. The rock slope database program provides procedures for gathering field data and rating the hazardous conditions of rock slopes. Secondary components of the database include statistical analyzers and engineering applications for performing “on-line” analysis of data, developing correlations between different soil parameters, and performing engineering analysis and designs. Procedures for entering historical soil and rock engineering data have been developed and programmed. Methods for “capturing” geotechnical data in a “real-time” mode, which will allow the storage of geotechnical data as it is generated, are currently being programmed. Issues concerning database security, engineering units, and storing and displaying maps, graphics, and photographs are discussed. The database contains procedures for dynamically overlaying the locations of landslides, rock slopes, and borings onto embedded roadway and digitized geological maps. Latitudes and longitudes of rock slopes and landslides were determined using Global Positioning System equipment (sub-meter accuracy). Strategies and illustrations of graphical user interfaces for data entry and retrieval are discussed. About 2086, potentially hazardous, rock slopes were rated numerically using the Rock Fall Hazard Rating system developed by the Oregon Department of Transportation and sponsored by the Federal Highway Administration (FHWA). A priority list of hazardous rock slopes can be generated rapidly.
title: Evolutionary and Swarm Algorithm Optimized Density- Based Clustering and Classification for Data Analytics
Creators: name: Guan, C
Publisher: name: University of Liverpool Repository
Year: 2018

description: Clustering is one of the most widely used pattern recognition technologies for data analytics. Density-based clustering is a category of clustering methods which can find arbitrary shaped clusters. A well-known density-based clustering algorithm is Density- Based Spatial Clustering of Applications with Noise (DBSCAN). DBSCAN has three drawbacks: firstly, the parameters for DBSCAN are hard to set; secondly, the number of clusters cannot be controlled by the users; and thirdly, DBSCAN cannot directly be used as a classifier. With addressing the drawbacks of DBSCAN, a novel framework, Evolutionary and Swarm Algorithm optimised Density-based Clustering and Classification (ESA-DCC), is proposed. Evolutionary and Swarm Algorithm (ESA), has been applied in various different research fields regarding optimisation problems, including data analytics. Numerous categories of ESAs have been proposed, such as, Genetic Algorithms (GAs), Particle Swarm Optimization (PSO), Differential Evaluation (DE) and Artificial Bee Colony (ABC). In this thesis, ESA is used to search the best parameters of density-based clustering and classification in the ESA-DCC framework to address the first drawback of DBSCAN. As method to offset the second drawback, four types of fitness functions are defined to enable users to set the number of clusters as input. A supervised fitness function is defined to use the ESA-DCC as a classifier to address the third drawback. Four ESA- DCC methods, GA-DCC, PSO-DCC, DE-DCC and ABC-DCC, are developed. The performance of the ESA-DCC methods is compared with K-means and DBSCAN using ten datasets. The experimental results indicate that the proposed ESA-DCC methods can find the optimised parameters in both supervised and unsupervised contexts. The proposed methods are applied in a product recommender system and image segmentation cases.

description: Let $K$ be a global or local field, $E/K$ a Galois extension, and Br$(E)$ the Brauer group of $E$. This paper shows that if $K$ is a local field, $v$ is its natural discrete valuation, $v'$ is the valuation of $E$ extending $v$, and $q$ is the characteristic of the residue field $\widehat E$ of $(E, v')$, then Br$(E) = \{0\}$ if and only if the following conditions hold: $\widehat E$ contains as a subfield the maximal $p$-extension of $\widehat K$, for each prime $p \neq q$; $\widehat E$ is an algebraically closed field in case the value group $v'(E)$ is $q$-indivisible. When $K$ is a global field, it characterizes the fields $E$ with Br$(E) = \{0\}$, which lie in the class of tame abelian extensions of $K$. We also give a criterion that, in the latter case, for any integer $n \ge 2$, there exists an $n$-variate $E$-form of degree $n$, which violates the Hasse principle.

Still Creek interpretation facility
Creators: name: Boothroyd, Gregory Stephen
Publisher: name: University of British Columbia
Year: 2009

description: This thesis explores the notion of site as a generative basis for architecture. Site is conceived not only as a plot of land where a building is located, but also as something that is the result of agency: the architectural intervention. Site is thus constructed with architecture; it is as much a consequence as a thing. Still Creek was chosen as a provocative site in which to explore this idea. Once Vancouver's largest salmon-bearing stream. Still Creek now exists in a barren, degraded state — the result of a century of urbanization. In its fragmented course from its headwaters to Burnaby Lake, Still Creek flows above and below ground through a diversity of site conditions, ranging from a primeval ravine to a polluted industrial area. Recently, sensibilities about the stream have changed. There are presently a variety of groups interested in Still Creek, not only as a public amenity, but also as an urban ecosystem. In response, it was proposed that (1) an urban trail be located along the discontinuous course of the stream, and (2) a facility be located along the stream that addresses some of the needs of these interested groups. The Still Creek Interpretive Facility marks both the beginning of the stream and the start of the urban trail. Located at the edge of the Renfrew Ravine where the stream first emerges from a subterranean culvert, the building makes apparent the many forces present on the site. An initial gesture of excavation reveals the culvert and demarcates a constructed and a natural edge. The constructed edge of the excavation is heightened with a veil of translucent solar panels that diffuse sunlight and help power the building. A wood screen along the natural edge of the excavation acts as a foil to the alder forest, allowing the building to maintain a quiet presence in the ravine as well as creating shimmering views of colour and light. The stream fills the lowest part of the excavation, mitigating high runoff flows and making a reflective pool for light, precipitation, and sound. The excavation and screen walls form a vessel into which mute volumes are inserted, creating a variety of indoor and outdoor spaces, some relating more to site, others relating more to programme. Exterior building circulation winds through the whole assembly — an extension of the urban trail — forming a rich experiential descent from street...through building...to stream beyond...

description: The Five-hundred-meter Aperture Spherical radio Telescope (FAST), the largest single dish radio telescope in the world, has implemented an innovative technology for its huge reflector, which changes the shape of the primary reflector from spherical to that of a paraboloid of 300 m aperture. Here we explore how the current FAST sensitivity can potentially be further improved by increasing the illuminated area (i.e., the aperture of the paraboloid embedded in the spherical surface). Alternatively, the maximum zenith angle can be increased to give greater sky coverage by decreasing the illuminated aperture.Different parabolic apertures within the FAST capability are analyzed in terms of how far the spherical surface would have to move to approximate a paraboloid. The sensitivity of FAST can be improved by approximately 10 % if the aperture of the paraboloid is increased from 300 m to 315 m. The parabolic aperture lies within the main spherical surface and does not extend beyond its edge. The maximum zenith angle can be increased to approximately 35 degrees from 26.4 degrees, if we decrease the aperture of the paraboloid to 220 m. This would still give a sensitivity similar to the Arecibo 305 m radio telescope. Radial deviations between paraboloids of different apertures and the spherical surfaces of differing radii are also investigated. Maximum zenith angles corresponding to different apertures of the paraboloid are further derived. A spherical surface with a different radius can provide a reference baseline for shape-changing applied through active reflector technology to FAST-like telescopes.

description: We give a general framework for the treatment of perturbations of types and structures in continuous logic, allowing to specify which parts of the logic may be perturbed. We prove that separable, elementarily equivalent structures which are approximately $\aleph_0$-saturated up to arbitrarily small perturbations are isomorphic up to arbitrarily small perturbations (where the notion of perturbation is part of the data). As a corollary, we obtain a Ryll-Nardzewski style characterisation of complete theories all of whose separable models are isomorphic up to arbitrarily small perturbations.
'Radicalising' the public sphere : from Habermas to Adorno

description: Jurgen Habermas's theory of communicative action continues to animate discussions on the nature of democracy in contemporary societies. Indeed there has been rarely a work of serious scholarship about the evolution of modern society that is not informed by the writings of this German philosopher. Yet there is a growing realisation that the evolution of contemporary societies has been accompanied by fundamental changes that have exerted strains on the relevance of Habermas's political philosophy. This fact has been popularly highlighted by that body of mainly French thought that comes under the rubric of poststructuralism. As a consequent there has been suggestion that the tradition of critical theory that Habermas is irrelevant. The dissertation agrees with the first argument: that the changes in contemporary societies have rendered Habermas's model of discursive democracy problematic. However, the conclusion of critical theory being in its twilight does not follow from this. The problem that is embedded within Habermas's oeuvre is well noted within the Frankfurt School. In fact, one of its original members anticipated the problems currently encountered by a communicative theory of society and puts forward a programme of critique that would ensure the continued relevance of Habermas and the critical tradition that he belongs to. The dissertation argues that a turn to Adorno's negative dialectics would address some of the debilitating features of Habermas's theory. Specifically, the incorporation of the insights of Adornos' dialectics into the theory of communicative action and by extension to the Habermasian public sphere would go a long way in realising the goals inherent in Habermas's political philosophy. This is to say that the current exercise stems from the conviction that an Adornian critique of communicative ethics, by way of a negative dialectics, offers improvements to Habermas's model of discursive democracy.
Growth of green wood based on a phase field model

description: Tree engineering is a young discipline utilizing trees as structural elements, where the determination of limit loads in tree trunks is of great importance. Simple numerical models underestimate the load-bearing capacity of green wood in contrast to experimental bending tests. A well-known reason for this is the residual stress state of the living tree lowering compressive stress towards the trunks surface. This results in an overall stress state, which increases the load capacity, since the tensile strength of wood is commonly higher than its compressive strength. By determining the residual growth stress, a more accurate evaluation of the load-bearing capacity of a living tree is possible. The residual stress state is a non-linear and time dependent function in thickness direction of the trunk. In order to simulate growth and growth stress, a phase field model is employed. The morphology of a tree is the result of innumerable and often temporary environmental stimuli, which also change and interact with the genetically predisposed growth tropisms. Therefore, we use image processing to capture the individual tree morphology of an existing tree, which is based within the phase field model as predefined growth direction. This is the basis for primary growth in the model. Additionally the model simulates the secondary growth, which corresponds to the thickness of the trunk. Except in tropical areas, this growth is associated with growth rings, which we assign as an attribute to the modelled material. While in the branch structure several tropisms (e.g. gravitropism) are responsible for the off-centre accumulation of woody material, in the stem region we only follow the stress-induced growth. This mechanism can respond to either the principal tensile stress or the principal compressive stress in our model, as this difference is observed in hardwoods and softwoods. Since the wood matrix represents an anisotropic material with a distinct fiber direction, we approach it in our model by a transversely isotropic constitutive law, whose principal direction coincides with the growth direction.

description: We experimentally determine isotropic and anisotropic g-factor corrections in lateral GaAs single-electron quantum dots. We extract the Zeeman splitting by measuring the tunnel rates into the individual spin states of an empty quantum dot for an in-plane magnetic field with various strengths and directions. We quantify the Zeeman energy and find a linear dependence on the magnetic field strength which allows us to extract the g-factor. The measured g-factor is understood in terms of spin-orbit interaction induced isotropic and anisotropic corrections to the GaAs bulk g-factor. Because this implies a dependence of the spin splitting on the magnetic field direction, these findings are of significance for spin qubits in GaAs quantum dots.

description: Highway improvements such as bypass construction typically are motivated by a desire to improve the flow and safety of travel. But, given the importance of travel, transportation improvement projects often can affect the local economy and quality of life. This study assesses these potential impacts. The study was conducted by the University of Kentucky Center for Business and Economic Research, as part of a subcontract with the Kentucky Transportation Center. The study is one component of a larger Kentucky Transportation Center study entitled Planning Decisions Related to Bypass Construction, Life-Cycle Costs of Access Control, and Safety Impacts of Rural Road Construction, which is being conducted for the Kentucky Transportation Cabinet.

description: Using archival Chandra data we studied the X-ray emission properties of PSR B2224+65 and its environment. Albeit limited by photon statistics the spectral analysis suggests that the bulk of the emission from PSR B2224+65 is non-thermal. Fitting a power-law to the observed energy spectrum yields a photon index of $Γ=1.58^{+0.43}_{-0.33}$. The possible origin of the non-thermal pulsar emission is discussed in the context of the outer-gap model. We did not find any evidence for a compact nebula around PSR B2224+65 though the Chandra data reveal the existence of an extended feature which appears to be associated with PSR B2224+65. It extends from the pulsar position about 2 arcmin to the north-west. Its orientation deviates by $\sim118^{\circ}$ from the pulsar's proper motion direction. Investigating its energy spectrum shows that the emission of this extended feature is much harder than that of the pulsar itself and is non-thermal in nature.

description: Changeable message signs (CMS) are used to communicate accurate, timely, and pertinent information to travelers on Kentucky’s roadways. This information helps travelers avoid hazards or delays and respond properly to changing roadway conditions. In an ideal environment, the Kentucky Transportation Cabinet (KYTC) would be able to allocate CMS to various areas of the state based upon changing needs. The location of each sign would be monitored, and the message could be controlled and checked remotely.  Currently these capabilities do not exist. KYTC has four different types of portable CMS in use throughout the state. Each type has different internal and external interfaces, and each requires different replacement parts. Also, there is no policy or guidelines in place for the use of these signs. The decision on how and when the CMS are used is made at the district level on a case-by-case basis.  This research effort includes an evaluation of Kentucky’s current inventory and usage of CMS, identification of key issues associated with the signs, and identification of state and regional policies on the management and use of CMS. Recommended guidelines for the management and use of CMS are included in this report.
title: Electronic Characterisation of Earth-Abundant Sulphides for Solar Photovoltaics
Creators: name: Whittles, TJ
Publisher: name: University of Liverpool Repository
Year: 2017

description: This thesis explores the electronic characterisation of materials for use as absorber layers within photovoltaic solar cells: an attractive solution to the energy crisis. Primarily, XPS was used to characterise CuSbS₂, Cu₃BiS₃, SnS, and Cu₂ZnSnS₄. All of these materials can be classified as earth-abundant: an important factor when considering materials that are both readily available and environmentally friendly. To varying degrees, all of these materials are established as potential absorber layers, with reports of successful, albeit low-efficiency devices. Also, the literature is often scant with regards to more fundamental characterisation of these materials, specifically in terms of how the underlying electronic structure affects properties that are pertinent to solar cells. Where XPS is utilised, it often lacks rigour, and is obfuscated by the complexities of the spectra. Work is then presented with two aims. First, to use a combination of high-quality XPS measurements and density of states calculations, in order to give insight into the electronic structure of the materials. Second, to present the full potential of XPS, as applied to solar absorbers, and how this technique complements others that are used for characterisation. Without exception, each material demonstrated natural band positions that make them unsuitable for use with established solar cell technologies. That is, a low IP (4.71–5.28 eV), resulting in a large CBO (0.5–0.85 eV) with CdS, for example. This offers some explanation to the poor efficiencies. These properties were found to be a consequence of the bonding nature of the valence and conduction bands, differing to the conventional absorber materials because of the influence of lone-pair electrons or other second-cation states. The power of XPS was demonstrated for application to absorber materials. The presence, effects, and formation pathways of contamination of the materials were elucidated using XPS, showing how the presence of such can act adversely to the performance of cells, especially with regards to oxidation, and also how these factors have been overlooked in the past. When coupled with other, complementary techniques, it has the ability to aid in the phase identification of a grown material, and also to help determine the presence of unwanted phases, which cause detriment to the device. For these applications, the methods, fitting procedures and analysis considerations detailed in this thesis should be followed. Research interest in these materials should be maintained based on the findings, with new approaches to cell design being aided by the characterisation methods developed here.

description: Ion conducting materials are critical components of batteries, fuel cells, and devices such as memristive switches. Analytical tools are therefore sought that allow the behavior of ions in solids to be monitored and analyzed with high spatial resolution and in real time. In principle, inelastic tunneling spectroscopy offers these capabilities. However, as its spectral resolution is limited by thermal softening of the Fermi-Dirac distribution, tunneling spectroscopy is usually constrained to cryogenic temperatures. This constraint would seem to render tunneling spectroscopy useless for studying ions in motion. We report here the first inelastic tunneling spectroscopy studies above room temperature. For these measurements, we have developed high-temperature-stable tunnel junctions that incorporate within the tunnel barrier ultrathin layers for efficient proton conduction. By analyzing the vibrational modes of O-H bonds in BaZrO3-based heterostructures, we demonstrate the detection of protons with a spectral resolution of 20 meV at 400 K (FWHM). Overturning the hitherto existing prediction for the spectral resolution limit of 186 meV (5.4 kBT at 400 K), this resolution enables high-temperature tunneling spectroscopy of ion conductors. With these advances, inelastic tunneling spectroscopy constitutes a novel, valuable analytical tool for solid-state ionics.

description: The objective of this research evaluation was to evaluate the reference markers which were installed on sections of interstates and freeways in the Cincinnati-Northern Kentucky area, the Lexington-Fayette Urban County area, the Louisville-southern Indiana area, and the Indianapolis area. The evaluation was conducted to determine if the use of reference markers at spacings of 0.1 or 0.2-mile intervals could improve the effectiveness of the emergency response and incident management processes. Also evaluated were color of the markers and the placement location within the right-of-way. Both "white on blue" and "white on green" markers were installed various projects, with some installed on the median barrier wall and some on grass medians or shoulders. Included were condition surveys of the marker installations and opinion surveys of those involved in the incident or emergency management process.  Nearly unanimous endorsement of the reference markers was received from interviews and surveys of highway agency personnel and participants in the emergency management process.  Recommendations were made for spacing of the markers at 0.2-mile intervals, with exceptions in curved sections to allow for placement of the markers at 0.1-mile intervals. Based on what appears to slightly increased conspicuity of the "white on blue" marker as compared to the "white on green" marker, it was recommended that a standardized reference marker be developed and incorporated in the Manual on Uniform Traffic Control Devices with white letters on blue background. Because of reduced exposure to mowing operations and errant vehicles, it was recommended that reference markers be placed on median barrier walls where practical. Recommendations were also made for a standard sign size and message content consistent with the reference markers evaluated in the three states.

description: Generalizing a previous work concerning cosmological linear tensor perturbations, we show that the lagrangians and hamiltonians of cosmological linear scalar and vector perturbations can be put in simple form through the implementation of canonical transformations and redefinitions of the lapse function, without ever using the background classical equations of motion. In particular, if the matter content of the Universe is a perfect fluid, the hamiltonian of scalar perturbations can be reduced, as usual, to a hamiltonian of a scalar field with variable mass depending on background functions, independently of the fact that these functions satisfy the background Einstein's classical equations. These simple lagrangians and hamiltonians can then be used in situations where the background metric is also quantized, hence providing a substantial simplification over the direct approach originally developed by Halliwell and Hawking.

description: Since the discovery of hypervelocity stars in 2005, it has been widely believed that only the disruption of a binary system by a supermassive black hole at the Galactic center (GC), that is, the so-called Hills mechanism, is capable of accelerating stars to beyond the Galactic escape velocity. In the meantime, however, driven by the Gaia space mission, there is mounting evidence that many of the most extreme high-velocity early-type stars at high Galactic latitudes do originate in the Galactic disk and not in the GC. Moreover, the ejection velocities of these extreme disk-runaway stars exceed the predicted limits of the classical scenarios for the production of runaway stars. Based on proper motions from the Gaia early data release 3 and on recent and new spectrophotometric distances, we studied the kinematics of 30 such extreme disk-runaway stars, allowing us to deduce their spatial origins in and their ejection velocities from the Galactic disk with unprecedented precision. Only three stars in the sample have past trajectories that are consistent with an origin in the GC, most notably S5-HVS1, which is the most extreme object in the sample by far. All other program stars are shown to be disk runaways with ejection velocities that sharply contrast at least with classical ejection scenarios. They include HVS5 and HVS6, which are both gravitationally unbound to the Milky Way. While most stars originate from within a galactocentric radius of 15kpc, which corresponds to the observed extent of the spiral arms, a group of five stars stems from radii of about 21-29kpc. This indicates a possible link to outer Galactic rings and a potential origin from infalling satellite galaxies.

description: Highway crashes cause a major impact to the transportation network by critically limiting the operational efficiency of the roadway. Traveler delay is the problem most often associated with highway crashes, but by far the most serious problem is the resulting secondary crashes that occur. Another related issue is the danger posed to response personnel serving the public at the scene. The magnitude of these problems is severe. A coordinated plan for managing the scene is needed to reduce the impact of highway crashes and improve the safety for everyone.  A Checklist and interagency workshop has been developed to address ways to secure and coordinate the resources necessary to restore the roadway’s operation in a safe and timely manner. This Checklist and workshop serve as a reminder to responding agencies of the activities that need to be performed and who needs to perform them. A highway crash scenario activity is part of the workshop and helps all the agencies involved at a crash scene to gain a better understanding of each other’s roles.  After the first workshop, 30 participants evaluated the Checklist and workshop. Ninety percent agreed that the workshop was helpful to them personally, and nearly 97% said they would encourage others to attend the workshop. Nearly 80% said they would use the Checklist on scene. Comments reflected that the interagency training was beneficial to them because it promoted communication and better understanding of everyone’s role at a crash scene.
A retailing trend for the 90s: megastores and their planning implications for British Columbian communities
Creators: name: Baker, Sarah Renee
Publisher: name: University of British Columbia
Year: 2009

description: Megastores are the latest phenomenon in the retail industry's evolution. This new form of retailing can be categorized by three main retail types: category killers, superstores and membership clubs. The arrival of megastores into British Columbia brings with it a variety of issues including economic, environmental, employment, aesthetic, social and planning. North American examples described in current literature detail these issues but do not directly address the role of the planner vis a vis megastores. Given that megastores are changing the retail geography and community development patterns of British Columbia, planners must have a comprehensive knowledge of their quantitative and qualitative impacts. To assist in an understanding of these impacts, two British Columbian megastore host communities are considered - Prince George and Courtenay. These case studies are assessed according to impacts delineated from the North American examples to determine the applicability of other research findings. Findings from this thesis show that megastores will become an important issue for British Columbia's planners and decision-makers in the years to come. The short history of megastores in the evolution of retailing make it difficult to evaluate their impacts. While some of the impacts found in the literature hold true for the British Columbian case studies, others do not. This divergence be attributable to the focus of available literature or the difference in exposure time to the megastore phenomenon. Further observation, research and analysis will be required to provide municipality specific data on which elected officials can base decisions.

description: In this work, we propose different variants of the self-attention based network for emotion prediction from movies, which we call AttendAffectNet. We take both audio and video into account and incorporate the relation among multiple modalities by applying self-attention mechanism in a novel manner into the extracted features for emotion prediction. We compare it to the typically temporal integration of the self-attention based model, which in our case, allows to capture the relation of temporal representations of the movie while considering the sequential dependencies of emotion responses. We demonstrate the effectiveness of our proposed architectures on the extended COGNIMUSE dataset [1], [2] and the MediaEval 2016 Emotional Impact of Movies Task [3], which consist of movies with emotion annotations. Our results show that applying the self-attention mechanism on the different audio-visual features, rather than in the time domain, is more effective for emotion prediction. Our approach is also proven to outperform many state-ofthe-art models for emotion prediction. The code to reproduce our results with the models' implementation is available at: https://github.com/ivyha010/AttendAffectNet.

description: Metallic cantilever in high vacuum atomic force microscope has been used as anode for field emission experiments from densely packed vertically aligned multi-walled carbon nanotubes. The high spatial resolution provided by the scanning probe technique allowed precise setting of the tip-sample distance in the submicron region. The dimension of the probe (curvature radius below 50nm) allowed to measure current contribution from sample areas smaller than 1um^2. The study of long-term stability evidenced that on these small areas the field emission current remains stable (within 10% fluctuations) several hours (at least up to 72 hours) at current intensities between 10-5A and 10-8A. Improvement of the current stability has been observed after performing long-time Joule heating conditioning to completely remove possible adsorbates on the nanotubes.

description: In the summer of 2000, it was decided by the Kentucky Transportation Cabinet that a portion of eastbound and westbound I-275 needed repair due to fatigue. The design was 10 inches PCC or 13 inches of asphaltic concrete for Section B, and 9 inches PCC or 12 inches of asphaltic concrete for Section A. Alternate bids were accepted from asphalt and concrete contractors with a required warranty of 10 years or 10,000,000 ESAL’s, which ever came first.  The Kentucky Transportation Center will be monitoring the performance of the pavement for the duration of the warranty and will be submitting an annual report showing any distress.  This report details the construction process and shows just a few of the minor problems that were encountered after the completion of construction.

description: Hierarchical Task Networks (HTN) are one of the most expressive representations for automated planning problems. On the other hand, in recent years, the performance of SAT solvers has been drastically improved. To take advantage of these advances, we investigate how to encode HTN problems as SAT problems. In this paper, we propose two new encodings: GCT (Grammar-Constrained Tasks) and SMS (Stack Machine Simulation), which, contrary to previous encodings, address recursive task relationships in HTN problems. We evaluate both encodings on benchmark domains from the International Planning Competition (IPC), setting a new baseline in SAT planning on modern HTN domains.

description: Food is an essential part of civilization, with a scope that ranges from the biological to the economic and cultural levels. Here we study the statistics of ingredients and recipes taken from Brazilian, British, French, and Medieval cookbooks. We find universal distributions with scale invariant behavior. We propose a copy-mutate process to model culinary evolution that fits very well our empirical data. We find a cultural founder effect produced by the nonequilibrium dynamics of the model. Both the invariant and idiosyncratic aspects of culture are accounted by our model, which may have applications in other kinds of evolutionary processes.
