The ethnographically informed participatory design of a PDA application to support communication
Creators: name: Davies, Rhian
Publisher: name: University of British Columbia
Year: 2009

description: Computer technology has been used successfully to assist people with severe physical deficits meet their communication needs. However, this success has not been met for people with cognitive deficits, such as aphasia. Aphasia is a language deficit resulting from trauma to the language centres of the brain. Aphasia can impact reading, writing, speaking, and/or the comprehension of spoken language. PDAs have a form factor and feature set that would appear to make them ideal communication devices. The first goal of this research was to address the communication needs of people with aphasia through exploring how a PDA could be used as a communication tool. The second goal was to adapt participatory design methodologies to better accommodate the needs of participants with aphasia. This research was conducted in three phases. In phase one, a researcher and participant with aphasia spent over 70 hours together, during which they: (1) gained a shared understanding of the communication strategies used by the participant, and (2) developed an understanding both of how a PDA could be incorporated into those strategies, and of the usability problems limiting the use of the PDA as a communication device. Through the field study, a shared context developed, and the researcher gained communication skills necessary to communicate successfully with the participant. In phase 2, an application to support the participant's communication strategies was designed using an ethnographically informed participatory design methodology, which leveraged the communication skills and shared context that had developed through the field study. In phase 3, the prototype application was evaluated in an experimental study, and in an informal field study based on the participant's use of the prototype in his daily life. This research was successful in adapting a PDA to better support the communication strategies of someone with aphasia. The evaluation of the prototype suggests many directions where future work would further increase the usability and usefulness of such an application. In addition, the field study highlighted other potential areas where computer technology could support the communication strategies of people with aphasia.

description: A bio-economic linear program based on data from 20 commercial extensive sheep farms was used to predict the effects on aspects of farm management of response to CAP reform in Great Britain. The objective function of the LP was to maximise gross margin while meeting ewe energy requirements from farm grown or purchased feeds on a monthly basis throughout the farming year. Three farms were constrained by availability of home-grown grass and thus contracted under a subsidy free scenario. Just one farm justified expansion using extra labour purchased at £5/hour. The other farms remained at current flock sizes using existing unpaid labour. However, all farms adjusted their grazing regime according to the balance of land types available. These adjustments varied from month to month, reflecting the complex and dynamic pattern of interactions between resource demand and supply throughout the farming year. The implied shifts in land use have implications for the environment and for animal welfare.

description: We report an experimental study of quantum transport for atoms confined in a periodic potential and compare between thermal and BEC initial conditions. We observe ballistic transport for all values of well depth and initial conditions, and the measured expansion velocity for thermal atoms is in excellent agreement with a single-particle model. For weak wells, the expansion of the BEC is also in excellent agreement with single-particle theory, using an effective temperature. We observe a crossover to a new regime for the BEC case as the well depth is increased, indicating the importance of interactions on quantum transport.

description: Most approaches to multi-talker overlapped speech separation and recognition assume that the number of simultaneously active speakers is given, but in realistic situations, it is typically unknown. To cope with this, we extend an iterative speech extraction system with mechanisms to count the number of sources and combine it with a single-talker speech recognizer to form the first end-to-end multi-talker automatic speech recognition system for an unknown number of active speakers. Our experiments show very promising performance in counting accuracy, source separation and speech recognition on simulated clean mixtures from WSJ0-2mix and WSJ0-3mix. Among others, we set a new state-of-the-art word error rate on the WSJ0-2mix database. Furthermore, our system generalizes well to a larger number of speakers than it ever saw during training, as shown in experiments with the WSJ0-4mix database.

description: We report here the properties of single crystals of La$_2$Ni$_2$In. Electrical resistivity and specific heat measurements concur with the results of Density Functional Theory (DFT) calculations, finding that La$_{2}$Ni$_{2}$In is a weakly correlated metal, where the Ni magnetism is almost completely quenched, leaving only a weak Stoner enhancement of the density of states. Superconductivity is observed at temperatures below 0.9$\,$K. A detailed analysis of the field and temperature dependencies of the resistivity, magnetic susceptibility, and specific heat at the lowest temperatures reveals that La$_2$Ni$_2$In is a dirty type-II superconductor with likely s-wave gap symmetry. Nanoclusters of ferromagnetic inclusions significantly affect the subgap states resulting in a non-exponential temperature dependence of the specific heat $C(T)$ at $T\ll T_\text{c}$.

description: We observed dynamically driven phase transitions in isentropically compressed bismuth. By changing the stress loading conditions we explored two distinct cases: one in which the experimental signature of the phase transformation corresponds to phase-boundary crossings initiated at both sample interfaces, and another in which the experimental trace is due to a single advancing transformation front in the bulk of the material. We introduce a coupled kinetics - hydrodynamics model that for this second case enables us, under suitable simplifying assumptions, to directly extract characteristic transition times from the experimental measurements.

The associated non-self-adjoint spectral problem is shown to be amenable to analysis using the isospectral deformations induced from the n-peakon solution, and the inverse problem is solved by a method generalizing the continued fraction solution of the peakon sector of the CH equation.

description: A triphenylene mesogen which possesses six dodecyloxyazobenzene units at the periphery linked by propylene-ether chain (2-C12-3) was synthesised and its mesomorphic phase transition behaviour was investigated. It was found that 2-C12-3 exhibits six mesophases including one monotropic phase. The calamitic-discotic bi-mesomorphic phase transition was also observed. As cooling the compound at the temperature of iso phase, SmA phase comes up and further cooling gives Colob phase. In comparison to the corresponding ester-linked derivative (1-C12-3), which shows only two mesophases (SmA and Colr), the linkage part connecting triphenylene unit and the peripheral alkoxyazobenzenes significantly affect the molecular ordering in mesophase, though the bi-mesomorphic property is maintained in the case of dedecyloxy chains.

description: We report a measurement of the E-mode polarization power spectrum of the cosmic microwave background (CMB) using 150 GHz data taken from July 2014 to December 2016 with the POLARBEAR experiment. We reach an effective polarization map noise level of $32\,μ\mathrm{K}$-$\mathrm{arcmin}$ across an observation area of 670 square degrees. We measure the EE power spectrum over the angular multipole range $500 \leq \ell <3000$, tracing the third to seventh acoustic peaks with high sensitivity. The statistical uncertainty on E-mode bandpowers is $\sim 2.3 μ{\rm K}^2$ at $\ell \sim 1000$ with a systematic uncertainty of 0.5$μ{\rm K}^2$. The data are consistent with the standard $Λ$CDM cosmological model with a probability-to-exceed of 0.38. We combine recent CMB E-mode measurements and make inferences about cosmological parameters in $Λ$CDM as well as in extensions to $Λ$CDM. Adding the ground-based CMB polarization measurements to the Planck dataset reduces the uncertainty on the Hubble constant by a factor of 1.2 to $H_0 = 67.20 \pm 0.57 {\rm km\,s^{-1} \,Mpc^{-1}}$. When allowing the number of relativistic species ($N_{eff}$) to vary, we find $N_{eff} = 2.94 \pm 0.16$, which is in good agreement with the standard value of 3.046. Instead allowing the primordial helium abundance ($Y_{He}$) to vary, the data favor $Y_{He} = 0.248 \pm 0.012$. This is very close to the expectation of 0.2467 from Big Bang Nucleosynthesis. When varying both $Y_{He}$ and $N_{eff}$, we find $N_{eff} = 2.70 \pm 0.26$ and $Y_{He} = 0.262 \pm 0.015$.

description: In valuing the demand for recreation, the literature has grown from using revealed preference methods to applying stated preference methods, namely contingent valuation and choice modelling. Recent attempts have merged revealed and stated preference data to exploit the strengths of both sources of data. We use contingent behaviour and choice experiments data to show that, with choice experiments exercises, when respondents are asked to choose which improvement programme they prefer for a site with recreational opportunities, failing to consider the information explaining the number of visits that respondents intend to take to a recreational site under each hypothetical programme leads to biased coefficients estimates in the models for the choice experiments data.

description: We study transfers of ions and debris from bioceramics implanted in bone sites. A contamination of surrounding tissues may play a major role in aseptic loosening of the implant. For these reasons, bioceramics require studies of biocompatibility and biofunctionality . So, in addition to in vitro studies of bioceramics, it is essential to implant them in vivo to know body reactions. We measured the concentration of mineral elements at different time intervals after implantation over a whole cross-section. We found a discontinuity of the mineral elements (Ca, P, Sr, Zn, Fe) at the interface between the implant and the receiver. The osseous attack is not global but, on the contrary, centripetal. Moreover, the fit of the concentration time course indicates that the kinetics of ossification is different for each atomic element and characterizes a distinct biological phenomenon

description: This paper analyzes the evolution of Swiss farm productivity during the implementation of environmental policy reforms. We employ a production model formulation with technology parameters defined as the functions of subsidies, as well as individual farm characteristics. Our estimates for two groups of farms – milk-producing and crop farms – show that introducing environmental regulations induced serious changes in the production technology and productivity of inputs, especially of land, labor and fertilizer. The overall effect of the subsidies on the production output has been found negative. At the same time, we find that farms do not use their resources optimally, which indicates some deficiencies in structural adjustments, primarily in the land and labor markets.

description: We study the zero-temperature quantum phase diagram for a two-component Bose-Einstein condensate in an optical cavity. The two atomic spin states are Raman coupled by two transverse orthogonally-polarized, blue detuned plane-wave lasers inducing a repulsive cavity potential. For weak pump the lasers favor a state with homogeneous density and predefined uniform spin direction. When one pump laser is polarized parallel to the cavity mode polarization, the photons coherently scattered into the resonator induce a polarization gradient along the cavity axis, which mediates long-range density-density, spin-density, and spin-spin interactions. We show that the coupled atom-cavity system implements central aspects of the $t$-$J$-$V$-$W$ model with a rich phase diagram. At the mean-field limit we identify at least four qualitatively distinct density- and spin-ordered phases including ferro- and anti-ferromagnetic order along the cavity axis, which can be controlled via the pump strength and detuning. A real time observation of amplitude and phase of the emitted fields bears strong signatures of the realized phase and allows for real-time determination of phase transition lines. Together with measurements of the population imbalance most properties of the phase diagram can be reconstructed.

description: Using centimeter wave and decimeter wave solar radio spectral observations of the flares of November 18, 2003 and September 12, 2004, we have discussed two type II like bursts at the meter waves. The radio bursts show that the ordinary frequency drift from high to low frequencies slows down and stops, and a frequency drift from low to high frequencies appears. An analysis of all data on the corresponding flares provides evidence of formation of quasi standing fast mode shocks (termination shocks, TS). TS are able to generate energetic electrons, responsible for the appearance of new sources of hard X ray radiation and generation of fast radio bursts (spikes), fibers and zebra structures. The sources of the radio emission bands with the unusual frequency drift are situated above the top of the post flare loops (lower TS) or are connected with the erupting prominence or coronal mass ejection (CME, upper TS). Estimations of the critical Mach numbers for the ordinary plasma parameters in the solar flares give the values 1.3 easily realized in the flare events. The conditions necessary for generation of unusual radio bursts are likely to occur in the helmet shaped magnetic structures in the solar corona.

description: We introduce a new method based on the first-order-reversal-curve (FORC) diagram to extract the intrinsic (microscopic) switching-field distribution (SFD) of perpendicular recording media (PRM). To demonstrate the viability of the method, we micromagnetically simulated FORCs for PRM with known SFD and compare the extracted SFD with the SFD obtained by means of two different methods that are based on recoil loops, too, which however rely on mean-field approximations and assumptions on the shape of the SFD. The FORC method turns out to be the most accurate algorithm over a broad range of dipolar interaction strengths, where the other methods overestimate the width of the SFD.

description: This paper modelled the participation decision of Irish farmers in an agri-environmental scheme. It also uses the sub sample of farmers in the National Farm Survey actively participating in the scheme in 2007 to model the various biodiversity options undertaken as a function of farmer demographic characteristics, farm characteristic and habitat variables. The results of the analysis demonstrate that younger, married farmers with larger farms are more likely to participate in REPS and that the voluntary aspect of REPS can mean that not all habitat types are equally likely to be covered by the scheme. Farmers with internationally important habitats on their farm, like intact peatlands or semi-natural grasslands are more likely to participate in REPS. However, there is evidence to suggest that these farmers are choosing to participate in REPS because they view their land as having low economic value rather than having high ecological value. Farmers with water or wetland and forest are less likely to participate in REPS, which indicates that some important ecosystems may not be included in the scheme. The 1 biodiversity options undertaken by the farmers are found to facilitate the management of the system of farming on the holing rather than the type of habitats on the land.
Voronoi ball models for computational shape applications
Creators: name: Tam, Roger C.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis evaluates the suitability of Voronoi ball models (VBMs) as a multipurpose shape representation for applications in computer graphics, scientific visualization, and computer vision. The effectiveness of VBMs is judged with respect to six key properties, namely stability, flexibility, accuracy, complexity, efficiency, and intuitiveness. These properties have a significant impact on the range of applicability of a computational shape model. The ability of VBMs to support a number of core shape-driven operations, in particular shape extraction, simplification, matching, interpolation, manipulation, and surface reconstruction, is examined by determining the strength of the key properties in the representation. The general approach is to use VBMs in a number of representative applications, each requiring several of the shape operations being considered. These applications include image matching and interpolation, shape model extraction from image data, two and three-dimensional shape simplification, and polygonal surface reconstruction. The performance of VBMs in these applications is indicative of the extent to which each key property is present. The results of the experiments are very positive. They indicate that a VBM-based shape similarity measure can be effectively applied to quantify 2D shape differences and solve the 2D/3D shape correspondence problem. The findings also show that the VBM and the medial axis can be used together to take advantage of their complementary properties; the VBM gives the medial axis greater stability, while the axis adds connectivity and topological information to the VBM representation. The preservation of the topology of 3D shapes during processing is a particularly strong contribution of the thesis. In addition, the medial axis is shown to enhance the capabilities of the VBM for performing shape simplification and partitioning an object into parts. The experimental results also reveal that VBMs can be effectively used to extract shape information from images and reconstruct polygonal surfaces from point sample data. The primary conclusion made in this thesis is that VBMs are demonstrably capable of supporting a wide variety of shape operations. Additional research is warranted to further exploit the potential of the representation.

description: Superlattices built from two antiferromagnetic (AFM) charge/orbital order compounds, $Pr_{0.5}Ca_{0.5}MnO_3$ and $La_{0.5}Ca_{0.5}MnO_3$, have been studied as the thickness of $La_{0.5}Ca_{0.5}MnO_3$ ($LCMO$) varied. High structural quality thin films were obtained on $LaAlO_3$ substrates using the pulsed laser deposition technique. An antiferromagnetic-to-ferromagnetic transition, in addition to an enhancement of the coercivity, are observed as the $LCMO$ layer thickness increases. The small shift in the origin of the field-cooled hysteresis loop along the field axis indicates the presence of ferromagnetic and antiferromagnetic phases in the superlattices. We attribute these features to the AFM spin fluctuations at the $Pr_{0.5}Ca_{0.5}MnO_3/La_{0.5}Ca_{0.5}MnO_3$ interfaces resulting from the strain effects.

description: In recent years, health risks have received increasing attention among consumers and created interest in analysing the relationship between food scares, food consumption and market prices. One of the most relevant and recent food scares is the avian influenza that has had important effects not only on human and animal health, but also on the economy. We assess effects of avian influenza on price transmission along the Egyptian poultry marketing chain. Although Egypt has been one of the most affected countries by avian influenza, this article is the first attempt to understand this food scare’s impacts on Egyptian poultry markets. In doing so, a multivariate smooth transition vector error correction model (STVECM) is applied to monthly poultry price data. In order to reflect consumer awareness of the crisis, an avian influenza food scare information index is developed and used within the model as a transition variable. Our results suggest that price adjustments to deviations from the market equilibrium parity depend on the magnitude of the avian influenza crisis. Results also suggest that food safety information indices, that have been widely used to assess the economic impacts of food scare crises in developed countries, also contribute to understanding the economic effects of food scare crises in developing countries.

description: The global financial crisis has hit hard international trade that dropped below levels not seen since the Great Depression with disastrous consequences for the developing world. This paper estimates an extended gravity model of trade on a sample of 83 developing countries over the period 1990-2007 to shed light on how banking crises and global economic downturns affect bilateral exports flows from developing countries. In addition to traditional variables, we include a trade finance variable and foreign aid among the regressors. Differences between developing regions are taken into account. Our results show that (i) trade finance has a positive and significant impact on bilateral export flows in all developing regions except Latin America; (ii) foreign aid matters in all regions; (iii) global economic downturns exert a negative and significant impact on export flows in all developing countries, and especially in Latin American and Sub-Saharan African economies; (iv) banking crises appear to have no significant impact in most regions.

description: The U.S. Renewable Fuel Standard program (RFS), which involves mandates for various biofuels, is complex and has been often misinterpreted or oversimplified in previous studies. In this paper we analyze the implications of the RFS for the U.S. domestic and international ethanol markets. We demonstrate the vital role of the advanced biofuel mandate within the RFS. Impacts of changes in tariffs on imported fuel ethanol and subsidies for U.S. domestic ethanol production are examined. One of our important findings is that the RFS could result in serious misallocation of resources in both a national and international context. There is a possibility that the United States could be required to import sugarcane-based ethanol to meet the advanced biofuel mandate, simultaneously exporting corn-based ethanol, while satisfying the national overall mandate. Since the provision of subsidies for domestic ethanol production can stimulate exports of corn-based ethanol, they are equivalent to export subsidies in this situation. The removal of tariffs can reduce the burden imposed on consumers in the United States from the operation of the RFS. Our analysis shows that it is extremely important to understand the potential impact of the RFS on agricultural and energy markets.

description: We analyze the performance of feedforward vs. recurrent neural network (RNN) architectures and associated training methods for learned frame prediction. To this effect, we trained a residual fully convolutional neural network (FCNN), a convolutional RNN (CRNN), and a convolutional long short-term memory (CLSTM) network for next frame prediction using the mean square loss. We performed both stateless and stateful training for recurrent networks. Experimental results show that the residual FCNN architecture performs the best in terms of peak signal to noise ratio (PSNR) at the expense of higher training and test (inference) computational complexity. The CRNN can be trained stably and very efficiently using the stateful truncated backpropagation through time procedure, and it requires an order of magnitude less inference runtime to achieve near real-time frame prediction with an acceptable performance.

Parallel computation of high dimensional robust correlation and covariance matrices

description: Currently, data mining applications use classical methods to calculate covariance and correlation matrices. These methods have the drawback that they can be adversely affected by data set outliers. Thus, robust methods for calculating covariance and correlation matrices are useful for these applications. However, robust methods require more time to calculate. To counter this, we propose two parallel robust methods of calculating correlation and covariance matrices. The first algorithm is a parallel version of Quadrant Correlation (QC), and the second is a parallel version of the Maronna method. Parallel QC uses a parallel matrix library and can handle single-dimensional outliers in its data. The parallel Maronna method divides the independent correlation calculations between the processors and is capable of detecting one and two dimensional outliers in data. We evaluate these algorithms using a dataset from a "real-life" application. It is a genetic data set that comes from cardiovascular research, and it contains 6068 variables. Our evaluation also includes performance results from datasets with varying dimensions, performance of several algorithm components, a communications analysis, and improvements for the Maronna method. ' From our results we conclude that our parallel algorithms make the robust calculation of correlation and covariance matrices useful in applications that deal with large dimensional data, such as data mining. Our initial hypothesis was that Maronna would perform better in parallel than QC, to the point that Maronna would be faster. In actuality, we found that Maronna does work better in parallel than a parallel QC in that it scales to more processors. However, our experiments do not show the parallel Maronna takes less time. Our conclusion is QC and Maronna are two viable options for computing robust correlation and covariance matrices. QC is less robust, fast, but does not scale as well to many processors while Maronna takes longer, is more robust, and scales to many processors.

description: A spatial equilibrium model based on a non-linear mathematical programming algorithm was developed to determine the optimal number, location, and size of cellulose ethanol plants for North Dakota. The objective function of the model is to minimize processing cost of biomass for ethanol and the transportation cost of shipping biomass to processing plants and ethanol to blending facilities. A heuristic approach, combined with a spatial equilibrium model, was used to determine the optimal number, location and size of biomass processing plants.

description: This report evaluates the U.S. and world sugar markets for 2009-2019 using the Global Sugar Policy Simulation Model. This analysis is based on assumptions about general economic conditions, agricultural policies, population growth, weather conditions, and technological changes. Both the U.S. and world sugar economies are predicted to remain stable over the next ten years in spite of the 2007-08 increase in world oil prices. That increase in oil price caused an increase in the conversion of sugar into ethanol in Brazil, while other exporting countries increased their production of sugar in response to higher sugar prices. Sugar prices remained strong in 2009 as the world’s economies recover slowly from the recession. World demand for sugar is expected to grow at a similar rate to world supply, resulting in Caribbean sugar prices remaining near the 16.0-19.0 cents/lb range throughout the forecast period. The U.S. wholesale price of sugar is projected to increase from 33.72 cents/lb in 2009 to 36.19 cents/lb in 2019, if Brazil continues to convert sugar into ethanol. It is projected that Mexico would be able to export 483 thousand metric tons of sugar to the United States by 2019. World trade volumes of sugar are expected to increase throughout the forecast period.

description: Fast Fourier transform based estimators are formulated for measuring momentum power spectra, including the auto power spectra of the momentum, the momentum divergence, and the cross spectrum of density fluctuation and momentum divergence. Algorithms using the third order Bettle-Lemarié scaling function to assign discrete objects to regular grids for fast Fourier transform are proposed to clean alias effects. Numerical experiments prove that the implementation can achieve sub-percent precision till close to the Nyquist frequency. Impact of removing bulk flow on estimation of momentum power spectra are derived theoretically and verified numerically, subtracting bulk flow has little effects at large scales but might induce meaningful differences in nonlinear regime, and probably it is not necessary to subtract bulk flow for samples which peculiar velocities are exact or sufficiently accurate. Momentum power spectra of dark matter samples from N-body simulation are measured and discussed. As expected, prediction of the one loop Eulerian perturbation theory agrees with simulation only slightly better than the linear theory at z=0, but can be applied to higher redshift with improved accuracy. Measurements of simulation data and the one loop Eulerian theory both reveal that the momentum field contains strong rotational part, and there is a large stochastic component in the divergence of momentum which is not correlated with the density field. The three kinds of momentum power spectra have their own characteristics.

description: We use a recently improved version of the chiral nucleon-nucleon potential at next-to-next-to-leading order to calculate the $^1S_0$ pairing gap in isospin-symmetric nuclear matter. The pairing potential consists of the long-range one- and two-pion exchange terms and two short-distance NN-contact couplings. We find that the inclusion of the two-pion exchange at next-to-next-to-leading order reduces substantially the cut-off dependence of the $^1S_0$ pairing gap determined by solving a regularised BCS equation. Our results are close to those obtained with the universal low-momentum nucleon-nucleon potential $V_{\rm low-k}$ or the phenomenological Gogny D1S force.
