My goal is to catch the moment in my paintings, whether it is an event from my busy everyday life or a slow formal arrangement of objects, that studies composition, light, color and movement. The drastic change in my life, traveling from Bangladesh to the United States, inspired me to render important small, quiet, little moments of my daily life by painting them. The intimacy of this connection is very important to me.

La Philosophie Poétique D'Édouard Glissant, Un Monisme Vitaliste, David Llorca

LSU Doctoral Dissertations

Édouard Glissant (1928-2011) is a world famous poet and novelist from French Island Martinique who, following the footsteps of Aimé Césaire, tried to heal the traumatic disruption and resolve the identity crisis of Creole people after the abominations of slavery and colonization by poetic sublimation and engaged thoughts. How is Glissant a philosopher? How does he articu-late poetry and philosophy together? What does he understand by “Relation”, why is it central in his thought and how does the articulation of all his concepts around it make a philosophical en-semble? How original and cohesive is this ensemble? Also, as we know …

Spectral Properties Of Photonic Crystals: Bloch Waves And Band Gaps, Robert Paul Viator Jr

LSU Doctoral Dissertations

The author of this dissertation studies the spectral properties of high-contrast photonic crystals, i.e. periodic electromagnetic waveguides made of two materials (a connected phase and included phase) whose electromagnetic material properties are in large contrast. A spectral analysis of 2nd-order divergence-form partial differential operators (with a coupling constant k) is provided. A result of this analysis is a uniformly convergent power series representation of Bloch-wave eigenvalues in terms of the coupling constant k in the high-contrast limit k -> infinity. An explicit radius of convergence for this power series is obtained, and can be written explicitly in terms of the …

Extensive Sensitivity Analysis And Parallel Stochastic Global Optimization Using Radial Basis Functions Of Integrated Biorefineries Under Operational Level Uncertainties, Santiago David Salas Ortiz

LSU Master's Theses

This work presents a decision-making framework for global optimization of detailed renewable energy processes considering technological uncertainty. The critical uncertain sources are identified with an efficient computational method for global sensitivity analysis, and are obtained in two different ways, simultaneously and independently per product pathway respect to the objective function. For global optimization, the parallel stochastic response surface method developed by Regis & Shoemaker (2009) is employed. This algorithm is based on the multi-start local metric stochastic response surface method explored by the same authors (2007a). The aforementioned algorithm uses as response surface model a radial basis function (RBF) for …

Lifetime And Efficiency Improvement Of Organic Luminescent Solar Concentrators For Photovoltaic Applications, Yamna El Mouedden

Theses: Doctorates and Masters

In order to achieve the goal of zero net-energy consumption in residential and commercial buildings, substantial research has been devoted to developing methods for energy harvesting from window glass that is capable of passing visible light through the windows of buildings while converting the unwanted invisible solar radiation into electricity. Research has focussed on two particular aspects, namely (i) the integration of thin-film technology for solar radiation transmission control and (ii) light guiding structures for solar radiation routing towards the edges of the glass window.

Recently, photovoltaic (PV) solar cells have been investigated and promoted as products for converting solar …

Recoverable Resources Calculation Using Non-Linear Methods: A Comparative Study, Matthew Cobb

Theses: Doctorates and Masters

The prediction of recoverable resources at an operating manganese mine is currently undertaken using univariate ordinary kriging of the target variable manganese, and 5 deleterious variables. Input data densities at the time of this calculation are considerably lower than at the time of final selection (grade control), and the potential for unnacceptable conditional bias to be introduced through the use of linear geostatistical methods when determining grade estimates over a small support has led to assessment of the potential benefit of employing the local change of support methods Localised Uniform Conditioning (LUC) and Conditional Simulation (CS). Allowances for the operating …

Influence Of Neural Network Training Parameters On Short-Term Wind Forecasting, Adel Brka, Yasir M. Al-Abdeli, Ganesh Kothapalli

Research outputs 2014 to 2021

This paper investigates factors which can affect the accuracy of short-term wind speed prediction when done over long periods spanning different seasons. Two types of neural networks (NNs) are used to forecast power generated via specific horizontal axis wind turbines. Meteorological data used are for a specific Western Australian location. Results reveal that seasonal variations affect the prediction accuracy of the wind resource, but the magnitude of this influence strongly depends on the details of the NN deployed. Factors investigated include the span of the time series needed to initially train the networks, the temporal resolution of these data, the …

Proactive Biometric-Enabled Forensic Imprinting, Abdulrahman Alruban, Nathan L. Clarke, Fudong Li, Steven M. Furnell

Research outputs 2014 to 2021

Threats to enterprises have become widespread in the last decade. A major source of such threats originates from insiders who have legitimate access to the organization's internal systems and databases. Therefore, preventing or responding to such incidents has become a challenging task. Digital forensics has grown into a de-facto standard in the examination of electronic evidence; however, a key barrier is often being able to associate an individual to the stolen data. Stolen credentials and the Trojan defense are two commonly cited arguments used. This paper proposes a model that can more inextricably links the use of information (e.g. images, …

Incorporating Field Studies Into Species Distribution And Climate Change Modelling: A Case Study Of The Koomal Trichosurus Vulpecula Hypoleucus (Phalangeridae), Shaun Molloy, Robert Davis, Eddie Van Etten

Research outputs 2014 to 2021

Species distribution models (SDMs) are an effective way of predicting the potential distribution of species and their response to environmental change. Most SDMs apply presence data to a relatively generic set of predictive variables such as climate. However, this weakens the modelling process by overlooking the responses to more cryptic predictive variables. In this paper we demonstrate a means by which data gathered from an intensive animal trapping study can be used to enhance SDMs by combining field data with bioclimatic modelling techniques to determine the future potential distribution for the koomal (Trichosurus vulpecula hypoleucus). The koomal is a geographically …

Controlled Access To Cloud Resources For Mitigating Economic Denial Of Sustainability (Edos) Attacks, Zubair A. Baig, Sadiq M. Sait, Farid Binbeshr

Research outputs 2014 to 2021

Cloud computing is a paradigm that provides scalable IT resources as a service over the Internet. Vulnerabilities in the cloud infrastructure have been readily exploited by the adversary class. Therefore, providing the desired level of assurance to all stakeholders through safeguarding data (sensitive or otherwise) which is stored in the cloud, is of utmost importance. In addition, protecting the cloud from adversarial attacks of diverse types and intents, cannot be understated. Economic Denial of Sustainability (EDoS) attack is considered as one of the concerns that has stalled many organizations from migrating their operations and/or data to the cloud. This is …

Sea Surface Temperature Variability In The Central-Western Mediterranean Sea During The Last 2700 Years: A Multi-Proxy And Multi-Record Approach, Merce Cisneros, Isabel Cacho, Jaime Frigola, Miquel Canals, Pere Masque, Belen Martrat, Marta Casado, Joan Grimalt, Leopoldo Pena, Giulia Margaritelli, Fabrizio Lirer

Research outputs 2014 to 2021

This study presents the reconstructed evolution of sea surface conditions in the central-western Mediterranean Sea during the late Holocene (2700 years) from a set of multi-proxy records as measured on five short sediment cores from two sites north of Minorca (cores MINMC06 and HER-MC-MR3). Sea surface temperatures (SSTs) from alkenones and Globigerina bulloides Mg / Ca ratios are combined with δ¹⁸O measurements in order to reconstruct changes in the regional evaporation–precipitation (E–P) balance. We also revisit the G. bulloides Mg / Ca–SST calibration and re-adjusted it based on a set of core-top measurements from the western Mediterranean Sea. …

Individual And Population-Level Responses To Ocean Acidification, Ben P. Harvey, Niall J. Mckeown, Samuel P. Rastrick, Camilla Bertolini, Andy Foggo, Helen Graham, Jason M. Hall-Spencer, Marco Milazzo, Paul W. Shaw, Daniel P. Small, Philippa J. Moore

Research outputs 2014 to 2021

Ocean acidification is predicted to have detrimental effects on many marine organisms and ecological processes. Despite growing evidence for direct impacts on specific species, few studies have simultaneously considered the effects of ocean acidification on individuals (e.g. consequences for energy budgets and resource partitioning) and population level demographic processes. Here we show that ocean acidification increases energetic demands on gastropods resulting in altered energy allocation, i.e. reduced shell size but increased body mass. When scaled up to the population level, long-term exposure to ocean acidification altered population demography, with evidence of a reduction in the proportion of females in the …

Phase Transformation And Deformation Behavior Of Niti-Nb Eutectic Joined Niti Wires, Liqiang Wang, Cong Wang, Laichang Zhang, Liangyu Chen, Weijie Lu, Di Zhang

Research outputs 2014 to 2021

NiTi wires were brazed together via eutectic reaction between NiTi and Nb powder deposited at the wire contact region. Phase transformation and deformation behavior of the NiTi-Nb eutectic microstructure were investigated using transmission electron microscopy (TEM) and cyclic loading-unloading tests. Results show that R phase and B19′ martensite transformation are induced by plastic deformation. R phase transformation, which significantly contributes to superelasticity, preferentially occurs at the interfaces between NiTi and eutectic region. Round-shaped Nb-rich phase with rod-like and lamellar-type eutectics are observed in eutectic regions. These phases appear to affect the deformation behavior of the brazed NiTi-Nb region via five …

A Multi-Point 2d Interface: Audio-Rate Signals For Controlling Complex Multi-Parametric Sound Synthesis, Stuart James

Research outputs 2014 to 2021

This paper documents a method of controlling complex sound synthesis processes such as granular synthesis, additive synthesis, timbre morphology, swarm-based spatialisation, spectral spatialisation, and timbre spatialisation via a multi-parametric 2D interface. This paper evaluates the use of audio-rate control signals for sound synthesis, and discussing approaches to de-interleaving, synchronization, and mapping. The paper also outlines a number of ways of extending the expressivity of such a control interface by coupling this with another 2D multi-parametric nodes interface and audio-rate 2D table lookup. The paper proceeds to review methods of navigating multi-parameter sets via interpolation and transformation. Some case studies are …

Responses Of Marine Organisms To Climate Change Across Oceans, Elvira S. Poloczanska, Michael T. Burrows, Christipher J. Brown, Jorge G. Molinos, Benjamin S. Halpern, Ove Hoegh-Guldberg, Carrie V. Kappel, Philippa J. Moore, Anthony Richardson, David S. Schoeman, William J. Sydeman

Research outputs 2014 to 2021

Climate change is driving changes in the physical and chemical properties of the ocean that have consequences for marine ecosystems. Here, we review evidence for the responses of marine life to recent climate change across ocean regions, from tropical seas to polar oceans. We consider observed changes in calcification rates, demography, abundance, distribution, and phenology of marine species. We draw on a database of observed climate change impacts on marine species, supplemented with evidence in the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. We discuss factors that limit or facilitate species' responses, such as fishing pressure, the …

Enhancing Student Learning By Narrowing The Gap Between Feedback Giving And Feedback Receiving, Eileen Goold

Conference Papers

Feedback is one of the most powerful influences on learning and achievement. However the mere provision of feedback to students does not necessarily lead to improved learning. Feedback is ineffective if it does not close the gap between learning goals and students’ performance. Often students do not have clear goals and they do not know what learning activities will improve their learning performance. Consequently the opportunity to learn from the feedback is lost. Learning is a social process and while young people have increasingly strong social needs they struggle with academic language. This study investigates the influence of lecturers’ feedback …

The interaction of the GM and the substrate was analysed using a range of surface analysis techniques including XPS, AFMIR and EDX. An example of a complex substrate, the zinc phosphate conversion coating, was analysed …

Compositional Changes For Reduction Of Polymerisation-Induced Shrinkage In Holo, Dervil Cody, Mohesh Moothanchery, Emilia Mihaylova, Vincent Toal, Svetlana Mintova, Izabela Naydenova

Doctoral

Polymerisation-induced shrinkage is one of the main reasons why many photopolymer materials are not used for certain applications including holographic optical elements and holographic data storage. Here, two compositional changes for the reduction of shrinkage in an acrylamide-based photopolymer are reported. A holographic interferometric technique was used to study changes in the dynamics of the shrinkage processes occurring in the modified photopolymer during holographic recording in real time. Firstly, the effect of the replacement of the acrylamide monomer in the photopolymer composition with a larger monomer molecule, diacetone acrylamide, on polymerisation-induced shrinkage has been studied. A reduction in relative shrinkage …

Frankenfolk: Distinctiveness And Attractiveness Of Voice And Motion, Jan Ondřej, Cathy Ennis, Niamh Merriman, Carol O'Sullivan

Articles

It is common practice in movies and games to use different actors for the voice and body/face motion of a virtual character. What effect does the combination of these different modalities have on the perception of the viewer? In this article, we conduct a series of experiments to evaluate the distinctiveness and attractiveness of human motions (face and body) and voices. We also create combination characters called FrankenFolks, where we mix and match the voice, body motion, face motion, and avatar of different actors and ask which modality is most dominant when determining distinctiveness and attractiveness or whether the effects …
