Using AspectJ to build a software product line for mobile devices
Creators: name: Young, Trevor J.
Publisher: name: University of British Columbia
Year: 2009

description: Software development for mobile devices has become very popular in the last few years. There are hundreds of programmable micro devices on the market, each having different properties in terms of memory capacity, screen size, networking protocols, audio/video support, peripheral extensions and software platforms. Despite the technical differences of these devices, people use them in a similar fashion for communicating, organizing and interacting with their personal data. For a mobile software developer, it would save a great deal of time and effort to program an application in a way that allows it to run on all of these devices without modification. However, the variability of hardware in these mobile phones, PDA's or music players has led the vendors to provide additional levels of software support for different devices. For example, with the Java programming language, vendors and standards bodies have introduced optional, device specific libraries (APIs) that only run on certain hardware devices. A software developer can thus not rely on standard programming practices to build an application that can run on multiple platforms and still offer features that take advantage of unique functionality that is only embedded in specific devices. We call this the device API fragmentation problem. One potential way to ease the development of a common application for a variety of devices is using Aspect-Oriented Programming (AOP) techniques to build a software product line. The basic idea is to modularize features into aspects and to use the weaving technology in aspect-oriented programming to bind features into different instances of the product line. In this thesis, we evaluate an approach for building a software product line for mobile devices using J2ME and AspectJ. We present different implementations of a prototype application to compare the AspectJ product line approach with standard object-oriented techniques that are currently used to build families of mobile Java software in industry. The results indicate that AspectJ provides a good solution to the device API fragmentation problem by maintaining modularity of features.

description: This paper applies the insights of the carbon leakage literature to study the emissions consequences of biofuel policies. We develop a simple analytic framework to decompose the intended emissions impacts of biofuel policy from four sources of carbon leakage: domestic fuel markets, domestic land markets, world land markets and world crude oil markets. A numerical simulation model illustrates the magnitude of each source of leakage for combinations of two current US biofuel policies: the Volumetric Ethanol Excise Tax Credit (VEETC) and the Renewable Fuel Standard (RFS). In the presence of both land and fuel market leakage, current US biofuel policies are unlikely to reduce greenhouse gases. Four of the five policy scenarios we consider lead to increases in greenhouse gas emissions. That is, total leakage was greater than 100%. The single scenario that generates emissions savings, the removal of the VEETC in conjunction with a binding RFS, only does so because negative leakage in the domestic fuel market offset the remaining positive sources of leakage.

description: We construct a new infinite family of N=1 quiver gauge theories which can be Higgsed to the Y^{p,q} quiver gauge theories. The dual geometries are toric Calabi-Yau cones for which we give the toric data. We also discuss the action of Seiberg duality on these quivers, and explore the different Seiberg dual theories. We describe the relationship of these theories to five dimensional gauge theories on (p,q) 5-branes. Using the toric data, we specify some of the properties of the corresponding dual Sasaki-Einstein manifolds. These theories generically have algebraic R-charges which are not quadratic irrational numbers. The metrics for these manifolds still remain unknown.

description: Minimum lot size zoning requirements are a frequent policy tool used to restrict the density and location of residential development. Zoning regulations are typically instituted and adopted locally, often with limited input from surrounding jurisdictions. Autonomous local land use regulations that constrain some, but not all development within a region create discrete differences in the returns to development across otherwise similar locations and are hypothesized to lead to a lower density, more scattered land development pattern. We examine the rural down-zoning policy in Baltimore County, Maryland in 1976 and its potential effect on creating urban growth spillovers in the adjacent counties. Using propensity score matching methods combined with a difference-in-difference econometric strategy, we find that this down-zoning policy resulted in significant spillover impacts to surrounding counties in areas observationally similar to those down-zoned in Baltimore County. To our knowledge, this is first analysis of regional spillover impacts resulting from zoning across county boundaries that relies on spatially disaggregated parcel-level data.

description: Multiple scattering of acoustic waves offers a noninvasive method for density estimation of a dense shoal of fish where traditional techniques such as echo-counting or echo-integration fail. Through acoustic experiments with a multi-beam sonar system in open sea cages, multiple scattering of sound in a fish shoal, and in particular the coherent backscattering effect, can be observed and interpreted quantitatively. Furthermore, a volumetric scan of the fish shoal allows isolation of a few individual fish from which target strength estimations are possible. The combination of those two methods allows for fish density estimation in the challenging case of dense shoals.

description: For functions defined on C^n or (R_+)^n we construct a dequantization transform, which is closely related to the Maslov dequantization. The subdifferential at the origin of a dequantized polynomial coincides with its Newton polytope. For the semiring of polynomials with nonnegative coefficients, the dequantization transform is a homomorphism of this semiring to the idempotent semiring of convex polytopes with the well-known Minkowski operations. Using the dequantization transform we generalize these results to a wide class of functions and convex sets.

Towards Inferring Queries from Simple and Partial Provenance Examples

Year: 2020
Subjects: subject: Databases (cs.DB)
subject: FOS: Computer and information sciences

description: The field of query-by-example aims at inferring queries from output examples given by non-expert users, by finding the underlying logic that binds the examples. However, for a very small set of examples, it is difficult to correctly infer such logic. To bridge this gap, previous work suggested attaching explanations to each output example, modeled as provenance, allowing users to explain the reason behind their choice of example. In this paper, we explore the problem of inferring queries from a few output examples and intuitive explanations. We propose a two step framework: (1) convert the explanations into (partial) provenance and (2) infer a query that generates the output examples using a novel algorithm that employs a graph based approach. This framework is suitable for non-experts as it does not require the specification of the provenance in its entirety or an understanding of its structure. We show promising initial experimental results of our approach.

description: We describe a systematic way of constructing effective divisors on the moduli space of stable curves of genus g having exceptionally small slope. We prove that any divisor on \bar{M}_g consisting of curves failing a certain Green-Lazarsfeld syzygy type condition, provides a counterexample to the Harris-Morrison Slope Conjecture. These divisors generalize our original isolated counterexample to the Slope Conjecture which was the divisor on M_{10} of curves lying on K3 surfaces. We also introduce a new stratification of M_g, somewhat similar to the classical stratification given by gonality, but where the analogue of hyperelliptic curves are sections of K3 surfaces. Finally, we prove that various moduli spaces M_{g,n} with g<23 are of general type.

description: This study investigates the effect of the economy structure on the U.S. - China bilateral trade deficit as alternative to the influence of the exchange rate fluctuation. The revealed comparative advantage indices are proposed as the measure of the relative structural differences between two countries due to factor endowments and technology. A Bayesian Stochastic Search Variable Selection method is applied to the U.S. - China annual trade data for 57 commodity groups at the SITC 2-digit industry aggregation level to obtain empirical variable inclusion probabilities. Based on the data, we found no conclusive evidence against the hypothesis of the short-run effect of either of the explanatory factors, while the long-run influence is revealed to be insignificant in most of the cases.

description: Com o aumento de preços e consumo do petróleo, tem-se procurado na biomassa alternativa energética renovável para sua substituição. Dentre as culturas capazes de atender à produção de insumo destinado à obtenção de energia renovável encontra-se a mamona. Objetivou-se, neste trabalho, conhecer o índice de variação estacional do preço da mamona, pois é essencial para a previsão de seu preço em determinada época do ano. Utilizou-se o preço da mamona recebido pelos produtores paranaenses e adotou-se a metodologia da média geométrica móvel centralizada de 12 meses, obtendo-se um padrão comportamental (sazonal). A análise mostrou que os preços tendem a ser maiores nos meses de janeiro a maio e, no período seguinte, a tendência é de queda de preços, coincidindo com o início da comercialização. Conclui-se que para os produtores as melhores épocas para a negociação da produção ocorrem durante os meses janeiro a maio e dezembro. Já os intermediários, devem realizar suas compras de junho a novembro de cada ano. -----------------------------------------------With the increase petroleum price and consumption, one have looked for renewable energetic alternative for its substitution. Among the crops capable of accommodating the input production designated to obtaining renewable energy castor bean is found. In this work, we aimed at recognizing the seasonal variation index of the price of castor bean, for it is essential for the prediction of its price in a determined period of the year. The price received by the producers from Paraná State was utilized and the methodology of the centralized mobile geometric average was applied. The analysis showed that the prices tend to be higher within the months from January through May and in the following period there is a tendency for decrease in prices coinciding with the beginning of commercialization period. One concludes that for the producers the best periods for the negotiation of the production occur within the months from January through May and December. The intermediators, however, must realize their purchases from June through November of each year.

description: We present results of two observing campaigns conducted by the OGLE-III survey in the 2003 observing season aiming at the detection of new objects with planetary transiting companions. Six fields of 35'x35' each located in the Galactic disk were monitored with high frequency for several weeks in February - July 2003. Additional observations of three of these fields were also collected in the 2004 season. Altogether about 800 and 1500 epochs were collected for the fields of both campaigns, respectively. The search for low depth transits was conducted on about 230000 stars with photometry better than 15 mmag. It was focused on detection of planetary companions, thus clear non-planetary cases were not included in the final list of selected objects. Altogether we discovered 40 stars with shallow (<0.05 mag) flat-bottomed transits. In each case several individual transits were observed allowing determination of photometric elements. Additionally, the lower limits on radii of the primary and companion were calculated. From the photometric point of view the new OGLE sample contains many very good candidates for extrasolar transiting planets. However, only the future spectroscopic follow-up observations of the OGLE sample - determination of the amplitude of radial velocity and exclusion of blending possibilities - may allow to confirm their planetary status. In general, the transiting objects may be extrasolar planets, brown dwarfs, M-type dwarfs or fake transits caused by blending. All photometric data of objects with transiting companions discovered during the 2003 campaigns are available to the astronomical community from the OGLE Internet archive.

description: (abridged) A detailed comparison is performed of the LFs compiled at infrared, radio and optical wavelengths and converted into XLFs using available relations with the XLF directly estimated in the 0.5--2 keV energy band from X-ray surveys (Norman et al). We find that the XLF from the local sample of IRAS galaxies (Takeuchi et al) provides a good representation of all available data samples; pure luminosity evolution of the form (1+z)^η, with η< ~3, is favoured over pure density. The local X-ray luminosity density is also well defined. We discuss different estimates of the galaxies LogN-LogS, selected from the Chandra Deep Fields with different selection criteria: these have similar slopes, but normalisations scattered within a factor ~2, of the same order of the Poissonian error on the counts. We compare the observed LogN-LogS with the counts predicted by integrating our reference z=0 XLF. By using number counts alone, it is not possible to discriminate between density and luminosity evolution; however, the evolution of galaxies must be stopped in both cases at z~1-2. The contribution of galaxies to the X-ray background is found to be in the range 6%--12%. Making use of cosmic star formation models, we find that the X-ray LogN-LogS might be not compatible with very large star formation rates at z ~ 3 as suggested by sub-mm observations in Blain et al. 1999. As to the content of current and, possibly, future X-ray surveys, we determine the fraction of galaxies around the current flux limit: (30+-12 %). At fainter fluxes the fraction of galaxies will probably rise, and overcome the counts from AGN at fluxes < ~10^{-17} erg/s/cm^2.

description: The inherent intermittency of renewable sources like wind and solar has resulted in a bundling of renewable generators with storage resources (batteries) for increased reliability. In this paper, we consider the problem of energy sharing between two such bundles, each associated with their own demand profiles. The demand profiles might, for example, correspond to commitments made by the bundle to the grid. With each bundle seeking to minimize its loss of load rate, we explore the possibility that one bundle can supply energy to the other from its battery at times of deficit, in return for a reciprocal supply from the other when it faces a deficit itself. We show that there always exist \emph{mutually beneficial} energy sharing arrangements between the two bundles. Moreover, we show that Pareto-optimal arrangements involve at least one bundle transferring energy to the other at the maximum feasible rate at times of deficit. We illustrate the potential gains from such dynamic energy sharing via an extensive case study.

Multi-image matching using invariant features
Creators: name: Brown, Matthew Alun
Publisher: name: University of British Columbia
Year: 2009

description: This thesis concerns the problems of automatic image stitching and 3D modelling from multiple views. These are basic problems of computer vision, with applications in robotics, architecture, industrial inspection, surveillance, computer graphics and film. Recent work has brought increasing automation to these tasks, but despite a large amount of progress, state-of-the-art algorithms still require some form of user input or assumptions about the image sequence. For example, the best image stitchers currently require an ordered set of input images, or user input to identify the matching images, before automatic registration can proceed. In this work we show how such tasks can be performed automatically and without any user input at all. We formulate the multi-image matching problem as one of finding all matching images, subject to the constraint that they are consistent views from a perspective camera. We use invariant features as a mechanism for finding correspondences, and indexing techniques to efficiently find matches between multiple views. We then find all sets of geometrically consistent feature matches, using a probabilistic model for verification. This allows us to identify each object or scene in the dataset using only the structure already present in the data. The major contributions of this thesis are the development of a system that can automatically recognise and stitch 2D panoramas in unordered image datasets, and a new class of invariant features for this purpose.

description: The NA62 experiment is a fixed-target experiment at CERN SPS. The main goal of the experiment is to measure the branching ratio of the ultra-rare kaon decay $K^{+}\toπ^{+}ν\barν$. The NA62 detector allows also to study other rare kaon decays and to search for very weakly coupled particles of MeV-GeV mass-scale. The new ANTI-0 hodoscope is proposed and designed to veto events with charged halo particles entering the decay volume. It is now being assembled at CERN. The detector design, the performance simulation and the results of measurements with cosmic rays and test beams for the individual elements are presented. The commissioning and the first run of data-taking is scheduled for after the end of LS2 long shutdown (April 2021).

description: This research presents a culmination of work into uncovering the underlying fluid dynamic behaviors of supercritical CO2 as it relates to high pressure turbine design using a combined fundamental and practical numerical and experimental analysis. The fundamental analysis of the thermo-fluid dynamic properties of supercritical CO2 boundary layers and separation is analyzed against the air counterparts for non-dimensional quantities of interest – pressure ratio, Mach number, Reynolds number – and combinations of these quantities. The coupling of density derivatives with pressure and temperature are investigated within the operating conditions of the first stage turbine of a supercritical CO2 oxyfuel power cycle. Armed with the information garnered from this analysis, a 3D optimization is run using computational fluid dynamics to investigated nearly 3000 unique blade shapes, focusing on increasing the isothermal corrected efficiency and decreasing the heat load to the blade. Three different families of blade shapes are identified from the analysis and their aerodynamic qualities discussed. A single advanced blade design is chosen for in depth analysis and experimental testing against the baseline blade from which the optimization was started. Mechanical design for the experimental campaign in the Big Rig for Aerothermal Stationary Turbine Analysis (BRASTA) is presented for a novel sector-based off-axis design and the results of the aerothermal measurements discussed. In tandem with blade design and analysis, the Tip Gap Experimental Research Article for Large Scale Injection Layouts (Tiger Lily), a canonical model for the large-scale investigation of tip flows in high Reynolds number flows, is developed and the mechanical and aerodynamic design discussed. Aerothermal analysis for different tip coolant injection configurations is performed using Improved Delayed Detached Eddy Simulation (IDDES) computational fluid dynamics analysis to resolve turbulent structures resulting from coolant injection and over tip flow interaction. Experimental investigation of Tiger Lily is presented, validating the structures and features seen in the numerical analysis. The conclusion of these investigations results in the increased understanding of the underlying fluid dynamic behaviors of supercritical CO2 in high pressure turbines.

description: The problem of objectivity, i.e. how to explain on quantum grounds the objective character of the macroscopic world, is one of the aspects of the celebrated quantum-to-classical transition. Initiated by W. H. Zurek and collaborators, this problem gained some attention recently with several approaches being developed. The aim of this work is to compare three of them: quantum Darwinism, Spectrum Broadcast Structures, and strong quantum Darwinism. The paper is concentrated on foundations, providing a synthetic analysis of how the three approaches realize the idea of objectivity and how they are related to each other. As a byproduct of this analysis, a proof of a generalized Spectrum Broadcast Structure theorem is presented. Recent quantum Darwinism experiments are also briefly discussed.

description: Starting from deformed quantum Heisenberg Lie algebras some realizations are given in terms of the usual creation and annihilation operators of the standard harmonic oscillator. Then the associated algebra eigenstates are computed and give rise to new classes of deformed coherent and squeezed states. They are parametrized by deformed algebra parameters and suitable redefinitions of them as paragrassmann numbers. Some properties of these deformed states also are analyzed.
