Combining Outputs From The North American Regional Climate Change Assessment Program By Using A Bayesian Hierarchical Model, Emily L. Kang, Noel Cressie, Stephan R. Sain
Combining Outputs From The North American Regional Climate Change Assessment Program By Using A Bayesian Hierarchical Model, Emily L. Kang, Noel Cressie, Stephan R. Sain

We investigate the 20-year-average boreal winter temperatures generated by an ensemble of six regional climate models (RCMs) in phase I of the North American Regional Climate Change Assessment Program. We use the long-run average (20-year integration) to smooth out variability and to capture the climate properties from the RCM outputs. We find that, although the RCMs capture the large-scale climate variation from coast to coast and from south to north similarly, their outputs can differ substantially in some regions. We propose a Bayesian hierarchical model to synthesize information from the ensemble of RCMs, and we construct a consensus climate signal …
Population Dynamics And Utilitarian Criteria In The Lucas - Uzawa Model, Simone Marsiglio, Davide La Torre
Population Dynamics And Utilitarian Criteria In The Lucas - Uzawa Model, Simone Marsiglio, Davide La Torre
Faculty of Business - Papers (Archive)
This paper introduces population growth in the Uzawa-Lucas model, analyzing the implications of the choice of the welfare criterion on the model's outcome. Traditional growth theory assumes population growth to be exponential, but this is not a realistic assumption (see Brida and Accinelli, 2007). We model exogenous population change by a generic function of population size. We show that a unique non-trivial equilibrium exists and the economy converges towards it along a saddle path, independently of population dynamics. What is affected by the type of population dynamics is the dimension of the stable manifold, which can be one or two, …

SCIAMACHY onboard ENVISAT (launched in 2002) enables the retrieval of global long-term columnaveraged dry air mole fractions of the two most important anthropogenic greenhouse gases carbon dioxide and methane (denoted XCO2 and XCH4). In order to assess the quality of the greenhouse gas data obtained with the recently introduced v2 of the scientific retrieval algorithm WFM-DOAS, we present validations with ground-based Fourier Transform Spectrometer (FTS) measurements and comparisons with model results at eight Total Carbon Column Observing Network (TCCON) sites providing realistic error estimates of the satellite data. Such validation is a prerequisite to assess the suitability …

Reducing Olanzapine-Induced Weight Gain Side-Effect By Using Betahistine: A Study In The Rat Model, Chao Deng, Jiamei Lian, Nagesh Brahmavar Pai, Xu-Feng Huang
Graduate School of Medicine - Papers (Archive)
Olanzapine is effective at treating multiple domains of schizophrenia symptoms. However, it induces serious metabolic side effects. Antipsychotic drug’s antagonistic affinity to histamine H1 receptors has been identified as a main contributor for weight gain/obesity side effects. This study therefore investigated whether a combined treatment of betahistine (a H1 receptor agonist and H3 receptor antagonist) could reduce the body weight/obesity induced by olanzapine. Female Sprague Dawley rats were treated orally with olanzapine (1 mg/kg, t.i.d.) and/or betahistine (2.67 mg/kg, t.i.d.), or vehicle for two weeks. Rats treated with olanzapine exhibited significant body weight gain and increased food intake. Co-treatment of …

Faculty of Engineering and Information Sciences - Papers: Part A
This study investigated the reduction of Pb(II)) by bioaccumulation and biosorption in an artificial biosorbent. The biosorbent was prepared by mixing grounded manure and fine-grain sand at a ratio of 1:1 (w/w) with the media packed into a laboratory scale column (diameter of 4.7 cm). The sweet soy sauce (food grade) solution with pH ranged of 5.0-5.5 and the concentration of 15 g COD L-1 was fed at a rate of 500 mL d-1 to the column surface for a period of 101 d. The active biofilm was then acclimatised for another 79 d, by adding 0.2 mg L-1 of …
A Novel Data Envelopment Analysis Model For Solving Supplier Selection Problems With Undesirable Outputs And Lack Of Inputs, Mahdi Mahdiloo, Reza Farzipoor Saen, Madjid Tavana
A Novel Data Envelopment Analysis Model For Solving Supplier Selection Problems With Undesirable Outputs And Lack Of Inputs, Mahdi Mahdiloo, Reza Farzipoor Saen, Madjid Tavana
Sydney Business School - Papers
Supplier evaluation and selection problems are inherently multi-criteria decision problems. Numerous analytical techniques ranging from simple weighted scoring to complex mathematical programming approaches have been proposed to solve these problems. Data Envelopment Analysis (DEA) has been used to evaluate suppliers' performance when there are multiple inputs and outputs in the supplier selection problem. The DEA determines the relative efficiencies of multiple suppliers. These relative efficiencies are then used to provide benchmarking data for reducing the number of suppliers. The DEA models used for supplier selection require numerical data for all the inputs and outputs for all the suppliers. However, this …

Improved Base-Calling And Quality Scores For 454 Sequencing Based On A Hurdle Poisson Model, Kristof De Beuf, Joachim De Schrijver, Olivier Thas, Wim Van Criekinge, Rafael A. Irizarry, Lieven Clement
Faculty of Engineering and Information Sciences - Papers: Part A
Background: 454 pyrosequencing is a commonly used massively parallel DNA sequencing technology with a wide variety of application fields such as epigenetics, metagenomics and transcriptomics. A well-known problem of this platform is its sensitivity to base-calling insertion and deletion errors, particularly in the presence of long homopolymers. In addition, the base-call quality scores are not informative with respect to whether an insertion or a deletion error is more likely. Surprisingly, not much effort has been devoted to the development of improved base-calling methods and more intuitive quality scores for this platform.

Accurate modelling of the radio channel is often the most difficult aspect of a Vehicular Ad Hoc Network (VANET) simulation due to the large variability present in vehicular terrain. CORNER is a propagation model that calculates path-loss in an urban terrain with a large concentration of buildings, based on the position of the transmitter and receiver on a street map. This paper proposes additions to the CORNER propagation model to take selective multi-path fading into account and investigates the performance of the GPSR routing protocol under the CORNER propagation model in a realistic city environment.

Parameter Estimation Of A Regime-Switching Model Using An Inverse Stieltjes Moment Approach, X Xi, Marianito R. Rodrigo, Rogemar S. Mamon
Faculty of Engineering and Information Sciences - Papers: Part A
We address the problem of recovering the time-dependent parameters of the Black-Scholes option pricing model when the underlying stock price dynamics are modelled by a finite-state, continuous-time Markov chain. The coupled system of Dupire-type partial differential equations is derived and formulated as an inverse Stieltjes moment problem. We provide numerical illustration on how to apply our method to simulated financial data. The accuracy of the model parameter estimation is examined and sensitivity analyses are included to study the behaviour of the estimated results when model parameters are varied.
A Note On Demographic Shocks In A Multi-Sector Growth Model, Simone Marsiglio, Davide La Torre
A Note On Demographic Shocks In A Multi-Sector Growth Model, Simone Marsiglio, Davide La Torre
Faculty of Business - Papers (Archive)
We introduce demographic shocks in a multi-sector endogenous growth model, a-la Uzawa-Lucas. We show that an analytical solution of the stochastic problem can be found, under the restriction that the capital share equals both the inverse of the intertemporal elasticity of substitution and the degree of altruism. We show that uncertainty lowers the optimal levels of consumption and the physical capital stock, while they do not affect the share of human capital employed in production.

Supplier selection is the strategy adopted by the manufacturer, to evaluate and select suppliers, which can fulfil the requirements of the manufacturer. To this end, data envelopment analysis (DEA), as a multiple criteria decision-making tool, has been applied for several times. However, conventional DEA models cannot simultaneously consider dual-role and non-discretionary factors. The objective of this paper is to propose a DEA model for ranking suppliers in the presence of both dual-role factors and non-discretionary inputs. A numerical example demonstrates the application of the proposed model. 2012 Inderscience Enterprises Ltd.

We retrieved column-averaged dry air mole fractions of atmospheric carbon dioxide (XCO 2) from backscattered short-wave infrared (SWIR) sunlight measured by the Japanese Greenhouse gases Observing SATellite (GOSAT). Over two years of XCO 2 retrieved from GOSAT is compared with XCO 2 inferred from collocated SWIR measurements by seven ground-based Total Carbon Column Observing Network (TCCON) stations. The average difference between GOSAT and TCCON XCO 2 for individual TCCON sites ranges from -0.87 ppm to 0.77 ppm with a mean value of 0.1 ppm and standard deviation of 0.56 ppm. We find an average bias between all GOSAT and TCCON …

Faculty of Engineering - Papers (Archive)
Supplier evaluation has become a significant topic over the past decades, as companies have started to become more outsourced oriented. However, previous research on this topic has not paid adequate attention to the limitations associated with availability of accurate and reliable data relating to the performance of potential suppliers. In an attempt to address this issue, this paper proposes a novel supplier evaluation model that can handle imprecise quantitative and qualitative data. Additionally, Decision Maker’s opinions regarding both qualitative and quantitative criteria are incorporated into this model so that a more comprehensive and realistic assessment of supplier performance can be …

Introduction To The Sydney Soil Model, Martin D. Liu, John P. Carter, David W. Airey
Faculty of Engineering - Papers (Archive)
In this paper a new constitutive model recently suggested by the authors, referred to as the Sydney Soil model, is introduced. The Sydney Soil Model is formulated within the framework of Critical State Soil Mechanics and is suitable for describing the behaviour of structured soils including both clays and sands. In the proposed model, the mechanical behaviour of soil is divided into two parts, that at a reference state and that attributed to the influence of soil structure. The reference state behaviour is formulated according to the soil properties at the critical state of deformation, based on the concept of …

Grain size, shape and orientation play an important role on the deformability of micro workpiece as the geometrical dimensions approach to a characteristic scale in micro-forming process. This paper addresses the three-dimensional (3D) finite element (FE) model with weighed centroidal voronoi diagram (WCVD). Steady-state grains are generated when the voronoi generating points approach the grain centroid utilising a simplex integration algorithm. As a result of the centroidal process, the topological features of grains advance the uniform and steady state gradually, which may cause a decrease of interfacial energy. The grain size distribution is compared between the 3D domain and random …

In this paper, finite element model is used to carry out thermal analysis of bead-on-plate welding. The model followed the proposed five step strategies which were then built into a model to obtain temperature history at the positions of thermocouples. Temperature field was also evaluated by comparing predicted weld bead with the actual weld bead. Using these proposed strategies, well matched temperature histories and temperature field have been obtained.

Business process (BP) can be supported by a large number of resources with evolving contents. In order to receive the support from these resources, the BP must satisfy the authorization policies of these resources. On the other hand, a BP also has its own authorization policies that users must satisfy in order to interact with the BP. Meanwhile, execution policies need to be applied to manage the sequence of tasks invocations in a BP. Therefore, without proper coordination among these policies, BP may not be able to perform correctly, e.g., imperative support from a specific resource could be missing or …

Faculty of Engineering - Papers (Archive)
A hysteretic stress-strain model is developed for unconfined concrete with the intention of providing efficient modelling for the structural behaviour of concrete in seismic regions. The proposed model is based on the findings of previous experimental and analytical studies. The model for concrete subjected to monotonic and cyclic loading comprises four components in compression and tension - an envelope curve (for monotonic and cyclic loading), an unloading curve, a reloading curve and a transition curve. Formulations for partial unloading and partial reloading curves are also presented. The reliability of the proposed constitutive model is investigated for a reinforced concrete member …

Discontinuities have a great influence on the reduction of rock mass shear strength depending on the geometry, roughness and the nature of infill sediments. These discontinuities are generally filled with different types of sediments. When the infill sediments are saturated, they make a considerable impact on the overall strength of the rock mass. Most infilled discontinuities in the field are overconsolidated due to various factors such as climatic and weathering conditions, as well as hydrothermal alteration. The increase in the thickness of joint infill subdues the otherwise prominent role of joint roughness. This paper presents some of the existing mathematical …

Adoption Of Mobile Commerce: A Confidence Model, Mohamed Khalifa, Sammi K. N Cheng, Kathy Ning Shen
University of Wollongong in Dubai - Papers
This study was driven by three underlying motivations. One of them is the gap between high penetration rate of mobile phone and relatively low adoption rate of m-commerce. The second is to reconcile the inconsistent findings in prior IT adoption research regarding the consistency of the relationship between attitude and intention. Finally, we hope to provide the theoretical underpinning for various interventions to promote m-commerce adoption. In this study, we extended the theory of planned behavior (TPB) by integrating confidence as a moderator for the relationship between attitude and intention. Furthermore, trial, communication and observation are identified as the sources …

The mathematic model of CVC-Plus work roll curve is built. The ratio of the initial shifting value to the target crown is determined, and the mathematical model considering the relationship between the coefficients A2, A3, A4, A5 and is established. According to the theoretical analysis, the distance between the maximum or minimum point of the high order equivalent crown for work roll with CVC-plus roll curve and the rolling central point is the times of the roll barrel length. In general, the initial shifting value of the CVC-plus roll curve is not equal to the initial shifting value of the …

Faculty of Engineering and Information Sciences - Papers: Part A
Disaster Management (DM) is a multidisciplinary endeavour and a very difficult knowledge domain to model. It is a diffused area of knowledge that is continuously evolving and informally represented. Metamodel is the output artefact of metamodelling, a software engineering approach, which makes statements about what can be expressed in the valid models of the knowledge domain. It is an appropriate high level knowledge structure to facilitate it being communicated among DM stakeholders. A Disaster Management Metamodel (DMM) is developed. To satisfy the expressiveness and the correctness of a DMM, in this paper we present a metamodel evaluation technique by using …

Stochastic Shocks In A Two-Sector Solow Model, Simone Marsiglio
Faculty of Business - Papers (Archive)
We study a stochastic, discrete-time, two-sector growth model à la Solow (1956) characterised by perpetual growth. Assuming that exogenous i.i.d. shocks hit the physical production sector, we show that the capital dynamics can be converted, through an appropriate log-transformation, into an iterated function system converging to an invariant distribution supported on a Cantor set.
