Year: 2025

description: As life expectancy continues to rise in modern society, the prevalence of age-related diseases hasalso increased. Alzheimer’s disease (AD), a common form of dementia that primarily affects older adults, isone such condition. AD is a progressive and irreversible brain disorder that gradually impairs memory,thinking, reasoning, and other cognitive abilities. The likelihood of developing Alzheimer's risessignificantly after the age of 65, with the disease's severity worsening over time. Early warning signs of ADinclude poor judgment, emotional changes, difficulty completing familiar tasks, misplacing items, troublesolving problems, and challenges with learning new things. Key risk factors for AD include smoking,hypertension, diabetes, obesity, and advancing age. In recent years, the number of AD patients hasincreased dramatically, particularly in developed countries with longer life expectancies.Machine learning and agent systems have made tremendous strides in various fields, includingweather forecasting, robotics, search engines, natural language processing, speech recognition, medicaldiagnosis, and handwriting recognition. Machine learning, a fundamental component of ArtificialIntelligence (AI), is an evolving technology that enables computers to "learn" by developing classifiers.This technology aims to address problems related to inference and prediction using available data, which isessential for decision-making by humans or intelligent systems like agent systems. An agent system refersto a computer system placed in an environment that can perform flexible, autonomous actions to achieve itsdesign goals. One key feature of agent systems is their ability to demonstrate intelligence throughinteraction. Intelligent agents possess reactive, proactive, and social characteristics. A multi-agent systemconsists of multiple agents that collaborate or compete to accomplish shared objectives.Several researchers have proposed different methods for predicting the stages of Alzheimer'sDisease (AD) using machine learning applied to various diagnostic techniques. While these studies havemade significant progress, some have focused solely on brain imaging scans for diagnosis, while othersrely on specialized devices that require patients to visit healthcare centers for evaluation.

description: The DFT-$\frac{1}{2}$ method is a band gap correction with GW precision at a DFT computational cost. The method was also extended to correct the gap between defect levels, allowing for the calculation of optical transitions. However, this method fails when the atomic character of the occupied and unoccupied defect levels are similar as we illustrate by two examples, the tetrahedral hydrogen interstitial and the negatively charged vacancy in diamond. We solve this problem by decoupling the effect of the occupied and unoccupied defect levels and call this the decoupled DFT-$\frac{1}{2}$ method for defects.

Nanoparticle manipulation and forced spreading within microscale acoustofluidic droplet systems

Publisher: name: Monash University

Subjects: Uncategorized

description: Lab-on-a-chip and micro-total-analysis systems are vital analytical tools used in both the biotechnology and nanotechnology industries. One of the most important aspects of this type of system is the ability to reliably control and manipulate the system itself or the sub-components located within the system such as cells. Audible frequency acoustofluidic actuation can provide a number of potential benefits for microfluidic procedures and is thusly investigated within this thesis. This thesis concentrates on two fundamental facets of manipulation of a microscale droplet system. The first aspect involves a previously undiscovered mechanism allowing manipulation of particles sized down to the nanoscale. The oscillatory motion of the fluid causes a time averaged linear relationship between particle and fluid flow. The intricate interplay between the hydrodynamic focussing and steady streaming effects must be controlled to optimise particle handling. The reduction in particle size has been achieved by minimising the strength of the acoustic streaming function and optimising the multiple-pass hydrodynamic focusing that acts on the particles. The magnitude of the scale reduction presented is quite significant, as particles as small as 190nm in diameter have been manipulated. The other aspect elucidates the harmonic fluidic motion’s ability to modify the wettability of a microscale droplet. The research conducted for this thesis has found that the forced spreading mechanism can be linked to the change in contact angle over an oscillation cycle. Over an oscillation period the temporal contact angle will spend more time in the advancing or receding segment depending on the direction of spreading. Consequently, this single oscillation period effect can result in droplet spreading over hundreds or thousands of oscillation cycles. The connection between the amplitude and the degree of spreading is via the oscillation mode. The behaviour of spreading changes when the droplet reaches larger accelerations. Distinct regions are defined each having different degrees of spreading. Moreover, the work conducted for this thesis has found that a droplet experiencing extremely large oscillations can spread so much that the drop can exceed its hysteretic limits. This mechanism can compel multiple droplets to evenly spread over a desired area and, subsequently, aid imaging of those drops. This thesis aims to highlight the prospective advantages that audible frequency actuation has over ultrasonic methods. These benefits include simpler instrumentation, higher transmission of particles, negligible temperature variation and synchronised manipulation of multiple samples.

description: We aim at constructing solutions to the minimizing problem for the variant of Rudin-Osher-Fatemi denoising model with rectilinear anisotropy and to the gradient flow of its underlying anisotropic total variation functional. We consider a naturally defined class of functions piecewise constant on rectangles (PCR). This class forms a strictly dense subset of the space of functions of bounded variation with an anisotropic norm. The main result shows that if the given noisy image is a PCR function, then solutions to both considered problems also have this property. For PCR data the problem of finding the solution is reduced to a finite algorithm. We discuss some implications of this result, for instance we use it to prove that continuity is preserved by both considered problems.

Incorporating detailed chemistry in reactive-flow simulations by exploiting system stiffness and processor architecture
Creators: name: Niemeyer, Kyle E.
Publisher: name: Zenodo
Year: 2018

description: Talk given in the Boulder Fluid and Thermal Sciences Seminar Series, University of Colorado, Boulder. Combustion simulations with finite-rate chemistry rely on accurate and efficient methods for solving stiff ordinary differential equations (ODEs). In a typical reacting-flow solver, the ODEs involving chemical kinetics at each spatial location are decoupled by operator splitting, allowing each to be solved concurrently. Efficient ODE solvers must take into account both numerical efficiency as well as the available thread and instruction-level parallelism of the underlying computational hardware being used to perform the simulations, especially on many-core coprocessors. This talk will summarize work on complementary efforts to reduce the computational expense of chemical kinetics on modern processing architectures. First, I will discuss the performance and behavior of exponential and implicit Runge-Kutta integrators implemented for graphics processing units (GPUs). Second, I will compare the performance of explicit Runge-Kutta and implicit Rosenbrock solvers implemented using both single instruction, multiple thread and single instruction, multiple data paradigms executed on multicore CPUs, Many Integrated Core, and GPU processors. Third, I will discuss efforts to intelligently select appropriate integrators based on local stiffness. I will then make overall conclusions based on a synthesis of the results, and identify remaining open questions and directions for future research. Lastly, I will discuss other ongoing research in my group.

description: We explore the use of graph networks to deal with irregular-geometry detectors in the context of particle reconstruction. Thanks to their representation-learning capabilities, graph networks can exploit the full detector granularity, while natively managing the event sparsity and arbitrarily complex detector geometries. We introduce two distance-weighted graph network architectures, dubbed GarNet and GravNet layers, and apply them to a typical particle reconstruction task. The performance of the new architectures is evaluated on a data set of simulated particle interactions on a toy model of a highly granular calorimeter, loosely inspired by the endcap calorimeter to be installed in the CMS detector for the High-Luminosity LHC phase. We study the clustering of energy depositions, which is the basis for calorimetric particle reconstruction, and provide a quantitative comparison to alternative approaches. The proposed algorithms provide an interesting alternative to existing methods, offering equally performing or less resource-demanding solutions with less underlying assumptions on the detector geometry and, consequently, the possibility to generalize to other detectors.

It reduces dynamically to general relativity plus a geometric Proca field. In this work, we study imprints of the geometric Proca field in the gravitational waves . Our results show that the geometric Proca leaves significant signatures in the gravitational wave signal, and gravitational wave energy density is large enough to be detectable by the next upgrade of the existing GW detectors. Our results, if confirmed observationally, will be an indication that the gravity could well non-Riemannian in nature.

Bacterial behaviour in an aerobic treatment lagoon at cooler temperatures: investigation into a decline in treatment efficiency during winter at Amcor Cartonboard Petrie Mill
Creators: name: Baigrie, Benjamin
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: A strong inverse correlation between temperature and organic load is present in the Petrie Mill main aerobic treatment lagoon which treats paper machine effluent. Lower temperatures experienced in winter months correspond to an increase in COD results at the pond outlet. This research and investigation was aimed at improving effluent treatment during cooler temperatures, by determining the extent of the impact of temperature in the treatment of effluent, as well as the influence of other factors such as oxygen or nutrient demand. Investigations and laboratory trials concluded that temperature did not directly impact the ability of the bacteria to consume the organic load. Ingestion of organics into the lagoon bacteria population occurred at the same rate across the temperature range tested. However, the dynamics of load reduction differed in a warmer versus a cooler environment. During lower temperatures, the catabolic requirements of bacteria are reduced, and the synthesis component of bacterial metabolism becomes an essential aspect of achieving the desired load reduction. The organic load was able to be effectively reduced at low temperatures, provided conditions were adequate for bacterial synthesis to occur. Temperature did not appear to affect bacterial synthesis. The impact extent of lower temperature appeared to be a reduced ability of excreted enzymes in biodegrading complex organic material. The major factors influencing organic load removal at lower temperatures were found to be those inhibiting bacterial synthesis, which were dissolved oxygen and nutrient availability. In the absence of adequate oxygen or nutrient supply, synthesis occurred at a lower rate or did not occur at all, leading to the poor treatment of effluent load at the low temperature. The investigation also included that the lagoon sludge bed had an impact on treatment during winter. Nutrients are absorbed by the sludge bed in cooler temperatures, contributing to possible nutrient deficiencies in winter. This would lead to reduced treatment efficiencies. Load variation also impacted on treatment performance, again due to higher organic loads without a corresponding increase in nutrient or oxygen availability for satisfactory bacterial synthesis. Toxicity had an inhibitory effect on bacteria functions. A number of immediate changes and have been made as a result of this investigation. Changes were based primarily on improving dissolved oxygen and nutrient availability, including redistribution of aerators and increasing nutrient dose rates. As a result the COD load at the lagoon outlet was reduced by approximately 20% and the system appears to be in a stable and robust condition entering the current winter period. It is anticipated that the implementation of recommendations for future improvement will further improve performance and robustness of the treatment system.

Atomisation and capillary wave generation in ultrasonically-actuated microfluidics
Creators: name: Blamey, Jeremy Kim
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: Ultrasonic surface acoustic wave (SAW) actuation is a promising technique for generating fluid flow in microfluidic devices, with many potential applications in fluid and particle manipulation. One particular application is ultrasonic atomisation, which has already been proposed as an effective means of generating fine particle mists for pulmonary drug delivery. The mechanism behind ultrasonic SAW-induced atomisation is the generation of large capillary waves on the fluid surface which, when at sufficient amplitude, can break off, forming small droplets. Capillary waves appear across a huge range of frequency and length scales in ultrasonic microfluidic systems. The physics behind the generation of these waves is not well understood. For the unstable waves that produce atomised droplets, the process of breaking and droplet ejection has been previously described, and some research has been done in determining the size of droplets ejected. However, the rate of atomisation, and its dependence on excitation level and frequency, is not known. In this thesis we experimentally measure the capillary wave vibrations induced by ultrasonic SAW actuation of a sessile drop, and the rate of atomisation from the drop. Our vibration measurements agree very precisely with the predictions of capillary wave turbulence theory, which predicts a broadband “cascade” power-law relation in the spectrum of vibration. Ours is the first description of wave turbulent behaviour in microfluidic systems; we demonstrate the power-law behaviour over three decades of frequency. We also identify an oscillation at the fundamental resonance frequency of the drop near 200 Hz, which we demonstrate to be directly induced by the excitation at 20 MHz. This fundamental resonance drives the wave turbulent cascade. The atomisation rate is directly connected to this resonance. We show that atomisation does not take place when the excitation level is below a particular threshold; beyond this threshold, atomisation rate steadily increases with excitation amplitude. The threshold behaviour of the resonance is the opposite: steadily increasing with excitation level up to the threshold, then remaining constant above the threshold.

Holographic correlation velocimetry: measuring 3D fluid flows
Creators: name: Higgins, Simon
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: Described in this thesis is an innovative method for measuring three dimensional (3D) velocity of a fluid at high speed, by combining a correlation-based approach with inline holography. While this method utilises tracer particles contained within the flow, the method does not require the reconstruction of individual particle fields. This is an advantage as less data is needed to acquired the same information as traditional methods. The method is also simpler to implement in an experimental setup. The Thesis outlines the theory behind the method, which has been termed Holographic Correlation Velocimetry (HCV), and subsequently demonstrates the application to both synthetic and laboratory data. This system is based on in-line holography and as such is very efficient with regard to the use of light, as it does not rely on side scattering as most other particle based approaches do. This efficiency could be utilised to create a very high quality system at a modest cost. Additionally, this efficiency significantly reduces the required exposure time, allowing measurement of high-speed flows, which is essential in dynamic systems such as industrial particle production. Other industry were this method include Natural Gas and Coal energy production, Biological cell culturing in Bioreactors or other systems and Blood flow with associated hemodynamics.

description: We present a novel approach to derive constraints on neutrino masses from cosmological data, while taking into account our ignorance of the neutrino mass ordering. We derive constraints from a combination of current and future cosmological datasets on the total neutrino mass $M_ν$ and on the mass fractions carried by each of the mass eigenstates, after marginalizing over the (unknown) neutrino mass ordering, either normal (NH) or inverted (IH). The bounds take therefore into account the uncertainty related to our ignorance of the mass hierarchy. This novel approach is carried out in the framework of Bayesian analysis of a typical hierarchical problem. In this context, the choice of the neutrino mass ordering is modeled via the discrete hyperparameter $h_{type}$. The preference for either the NH or the IH scenarios is then encoded in the posterior distribution of $h_{type}$ itself. Current CMB measurements assign equal odds to the two hierarchies, and are thus unable to distinguish between them. However, after the addition of BAO measurements, a weak preference for NH appears, with odds of 4:3 from Planck temperature and large-scale polarization in combination with BAO (3:2 if small-scale polarization is also included). Forecasts suggest that the combination of upcoming CMB (COrE) and BAO surveys (DESI) may determine the neutrino mass hierarchy at a high statistical significance if the mass is very close to the minimal value allowed by oscillations, as for NH and $M_ν=0.06$ eV there is a 9:1 preference of NH vs IH. On the contrary, if $M_ν$ is of the order of 0.1 eV or larger, even future cosmological observations will be inconclusive. The unbiased limit on $M_ν$ we obtain with this innovative statistical strategy is crucial for ongoing and planned neutrinoless double beta decay searches.

description: Solving humanity's social-environmental challenges calls for collective action by relevant actors. Hence, involving these actors in the policy process has been deemed both necessary and promising. But how and to what extent can participatory policy interventions (PIs) foster collective action for sustainable environmental and natural resource management? Lab and lab-in-the-field experiments on co-operation in the context of collective action challenges (i.e. social dilemmas) and case study research on participatory processes both offer insights into this question but have hitherto mainly remained unconnected. This article reviews insights from these two streams of literature in tandem, synthesising and analysing them using the institutional analysis and development (IAD) framework in combination with the network of action situations (NAS) framework and the social-ecological systems (SES) framework. We thus perform an integrative and interpretative narrative review to draw a richer and more nuanced picture of PIs: their potential impacts, their (institutional and behavioural) mechanisms and challenges, and caveats and recommendations for their design and implementation. Our review shows that PIs can indeed foster collective action by (a) helping the relevant actors craft suitable and legitimate institutional arrangements and (b) addressing and/or influencing actors' attributes of relevance to collective action, namely their individual and shared understandings, beliefs and preferences. To fulfil this potential, the organisers and sponsors of PIs must address and link to the broader context through soundly designed and implemented processes. Complementary follow-up, enforcement and conflict resolution mechanisms are necessary to nurture, reassure and sustain understandings, beliefs and preferences that undergird trust-building and collective action. The conceptual framework developed for the review can help researchers and practitioners further assess these insights, disentangle PIs' mechanisms and impacts, and integrate the research and practice of participatory governance and collective action.

description: Recently, the worldwide market value of glycerin has proliferated owing to its major role as an active ingredient in food, cosmetic and personal care product. The rapid growth of biodiesel industries in the past decade has emerged as a reliable source of glycerin in significant amount. Glycerin is produced as a by-product from transesterification process in the biodiesel production, accounting up to 12 % of the total biodiesel production capacity. In general, the crude glycerin effluent oftentimes encompasses glycerin in a concentration range of 3 – 60 wt%. A series of separation and purification processes are normally practiced to purify the crude glycerin into 99 wt% purified glycerin. These include evaporation, vacuum distillation and product refinement processes such as ion exchange and bleaching. The capital and operating cost of these processes are high and usually involve the use of chemicals. In this regard, the potential of utilizing membrane technology in purifying crude glycerin solution is interminable. Membrane technology is a chemical-free process. At the same time, it possesses advantageous characteristics such as environmental friendly and operation simplicity. To date, there is limited study reported on the application of membrane technology in glycerin purification process. The main aim of this project was to investigate the feasibility of membrane technology in glycerin purification. In the present study, crude glycerin purification processes were carried out through ultrafiltration for removal of palm oil and fatty acids, further removal of palm oil using nanofiltration, water extraction using reverse osmosis and dehydration of glycerin using pervaporation. The first stage of this study demonstrated that ultrafiltration was capable of removing palm oil and oleic acid from glycerin solution with the highest rejection of 87.00 and 98.59 %, respectively. Next, data fitting of Hermia’s model showed that cake layer formation was the most consistent fouling mechanism during ultrafiltration process. Besides, multistage Hermia’s model offered a more comprehensive description of the overall fouling mechanism, which indicated the transition period of fouling from standard blocking to cake layer formation. Following ultrafiltration, the optimization of operating parameters using central composite rotatable design in a nanofiltration process revealed that 40 oC, 60 bar and 1 L/min contributed to the best performance of nanofiltration, with 97.55 % of glycerin permeation and 265.64 kg/m2.h of permeate flux recorded. Palm oil rejection of above 99 % was evident at the optimum condition in a steady state nanofiltration. In reverse osmosis, TFC-HR membrane yielded the highest glycerin rejection of 99.81 % along with the permeate flux of 11.86 kg/m2.h using crossflow configuration. Finally, HybSi pervaporation membrane was successfully dehydrating glycerin solution up to 99 wt% with the permeate flux and permeance water content of 13.63 kg/m2.h and 98 wt%, respectively.
