Subjects: Art market; Sotheby's; Contemporary Chinese Art; Auctions

description: On 31 October 2004, Sotheby’s conducted an auction in Hong Kong under a new category entitled ‘Contemporary Chinese Art’. This was not the first time that either of the multinational auction houses had included contemporary Chinese art in their auction offerings; however, in the decade leading up to this auction, contemporary Chinese art was primarily included in the broader sale category titled Modern and Contemporary Chinese Paintings. By late 2004, Henry Howard-Sneyd, Sotheby’s Managing Director, China, Southeast Asia and Australasia, was cognisant of a significant shift in international market interest in Chinese art of a style comparable to contemporary international art. In fact, Christie’s had offered a substantial number of artworks in this style at an auction in London in October 1998 titled Asian Avant Garde. However, Christie’s auction, which included Japanese, Korean and Chinese contemporary art, was poorly attended and a financial failure. Consequently, Christie’s abandoned this auction category. So what had occurred over the intervening six years that gave Sotheby’s encouragement to inaugurate this auction category?

This article is structured around a unique methodology whereby examination of the contents of the auction catalogue including artists, artworks, provenance, date of production and medium provides a framework for analysis of this emergent auction category. The contextual analysis of Sotheby’s inaugural auction in October 2004 illuminates the networked activities of a small group of dealers, critics and curators acting as cultural mediators to create a global market for the artwork of a select group of Chinese artists. The activities of this network are underpinned through the symbolic value imbued by international museum exhibitions of contemporary Chinese art presented as provenance and exhibition history. According to the 2007 TEFAF report, global art auction sales for contemporary Chinese art grew nearly two hundredfold between 2003 and 2007. This article thereby aims to contribute to an understanding of how the global auction market for contemporary Chinese art was inaugurated and developed.

Light and illusion
Creators: name: Lincoln, Lucy
Publisher: name: RMIT University
Year: 2024

description: This project is an investigation of visual illusions created through the interaction of light on different surfaces and structures. Illusion implies deception - an optical illusion, in a sense is misunderstood information that creates a 'false' visual reality. This project incorporates macro and non-macro photography to generate illusion through scale and shape. Through deliberate acts of deception the images play on the human desire for mystery. It is through the 'eye of the imagination' that the images reveal themselves. The photographic images are of dioramas created on the top of a light box, using everyday substances and materials such as glass, felt, coloured transparencies, detergents and liquids of varying consistencies. This project reveals the extraordinary in the ordinary. The outcome of this project is a photographic body of work, the product of my experimentation and research, in which the ambiguous content of the composition, compels the viewer to their own interpretation. Translating some of the resulting images into a three-dimensional light based installation of an illusory nature invites people to take on a participatory role, furthering their experience with the artwork. This project makes us aware of our role within the experiential process, ma king us appreciate and question its very nature.
East Asian Art in the Gurlitt Collection: Tracing the Relationship of Objects and Actors
Creators: name: Neumann, Nathalie
Publisher: name: Journal for Art Market Studies
Year: 2018

description: For the so-called Gurlitt Collection, which was seized in the spring of 2012 at the home of Cornelius, son of the art dealer Hildebrand Gurlitt , research has been concluded after five years of intense work, an extensive exhibition catalog and four comprehensive publications on the collection and biography of Gurlitt. The research project , which expires at the end of 2018 and has the mission to determine the prior ownership of the works of art, underlies the Minister of Culture, and research results to all works from the holdings of Gurlitt are continuously published on the homepage www.lostart.de hosted by the DZK (Deutsches Zentrum Kulturgutverluste).
According to his taste and strategies, the stock of the art historian and dealer Gurlitt holds today several hundreds of prints of so-called "de-generated art", as well as paintings, drawings and prints from the 16th to 19th centuries, from the hand of German, French as well as Dutch and Flemish artists. It might be less known that he also had a small number of East Asian arts among them, most of which come from Japan. The article reports on a selection of these art objects to present methods, resources, and some results.

Hysteresis current regulation of voltage source inverters with constant switching frequency
Creators: name: Davoodnezhad, Reza
Publisher: name: RMIT University
Year: 2024

description: The thesis presents an integrated approach for constant frequency closed-loop hysteresis current control of a VSI. The proposed approach uses the fact that the switching frequency of a fixed-band hysteresis-controlled inverter varies according to the average load voltage. A novel technique is used to measure this average voltage by capturing transition times of the phase leg switching events, to avoid the frequency roll-off effects of using a low pass filter. The average voltage is then used to vary the hysteresis band in order to keep the VSI switching frequency constant. Next, a refinement is applied to the variable band to synchronise the zero-crossing of the current error to a fixed reference clock. The zero-crossing time is calculated by linearly interpolating between the captured switching transition times, to avoid the need for direct measurement of the zero-crossing event. This achieves a more robust and accurate synchronization process compared to current state-of-the-art time-based and deadbeat hysteresis controllers. For a three-phase VSI, the common mode current is subtracted from the phase leg current error that is calculated from three-phase leg gate signals. Further enhancements are then presented to extend the linear modulation range by 15%, to maintain excellent switching stability during excursions into overmodulation and to replace the third phase regulator with a fixed frequency directly modulated phase leg. The overall result is a two-level hysteresis current control approach with a harmonic performance that is similar to open-loop CSVM.

The average voltage calculation of the phase leg switched voltage then allows the integrated control concept to be applied to three-level three-phase multilevel topologies. Firstly, it allows the development of a three-level variable hysteresis band with band refinement similar to a two-level inverter. Secondly, it facilitates the development of a logic decoder based on the identification of the average voltage zero-crossings, so that only one hysteresis comparator is required per phase leg. A finite state machine is then developed to utilize the redundant switching states of the VSI similar to open-loop phase-shifted PWM. The control concept is then extended to suit a three-phase system by compensating for the common mode interacting current in a similar way as was done for two-level inverters. Further developments are then presented to synchronize the three-phase current errors to a fixed reference clock. The overall result is a three-level hysteresis current control approach that achieves a performance similar to open-loop phase disposition (PD) pulse width modulated three-phase multilevel inverter.

Australia's changing workplace: a generational perspective
Creators: name: Sayers, Roslyn
Publisher: name: RMIT University
Year: 2024

description: This research investigates generational differences in Australian workers. In particular it focuses on changing trends and influences in the workplace and how different generations view and deal with these changes. The study focuses on Baby Boomers (born 1945-1963), Generation X (born 1964-1977) and Generation Y (born 1978 - 1994) across four industry sectors: Corporate, Education, Government and Not for Profit.

The Australian workforce currently consists of four generations - all having distinct characteristics, working styles, needs and expectations. These differences pose challenges and opportunities to workforce management. The first step in managing the generations and their differences is to identify where the differences lie and to understand how best to cope with and exploit these differences. This research, in taking a generational cohort perspective towards analysing the modern workplace, seeks to explore how the different generations view the trends and influences that impact their work; and their attitudes towards technology, communication, work/life balance, organisational loyalty, attraction, engagement and retention.

The study uses a multi-phase qualitative approach and includes in-depth interviews with a range of Australian industry experts; discussion groups held with Gen Ys, Gen Xers and Baby Boomer employees, in four organisations across four industry sectors; and in-depth interviews with senior executives in the same four organisations.

This research will have significance to all organisations especially those that employ workers from across the generations and who are managing a multigenerational workforce. The findings will have practical application to organisational policy development in areas such as, work/life balance, attraction, engagement and retention of employees, reward and recognition systems, technology in the workplace and training and development.

The study adds to the body of knowledge in workforce management, and in particular to the emerging body of knowledge on generational cohort analysis of the workplace in the Australian context. The study found significant generational differences that when harnessed and managed effectively, can contribute to the output and performance of the organisation as a whole.
Towards creating sustaining futures: a philosophy of (engineering) practice for the 21st century
Creators: name: Goricanec, Jennifer
Publisher: name: RMIT University
Year: 2024

description: This thesis proposes a re-conceptualisation of engineering practice that moves towards responding to the nature of our 21st Century (21C) predicament – the dynamic, turbulent, labyrinthine flux which has developed through the inhabitation of modern humanity in our open living world.

It describes a philosophy and practices to achieve this. Key concepts are the context within which practice takes place and an integrated approach at the system level. Together these principles promote processes and practices that can design life situations which are more desirable and feasible, not only for humanity but to strengthen our natural environment. This is active adaptive planning; it changes practitioners’ relationship with the world by providing spaces where the agenda is not “driven” by the “push” of the past but elicits the “pull” of future intentions. Using these approaches people are engaged collectively in processes that re-connect with context taking into account the relevant uncertainties across what are often articulated as “different” systems (e.g. social, environmental, technical) and between past, present, future. Further, it works the loops – performing ontological politics that is linking and knotting what emerges from these processes with all the potential stakeholders, mobilising resources, peers, allies and the public.

The thesis identifies links between Socio-Technical Systems, Actor-Network Theory and process philosophy. This extends Actor-Network Theory which has already removed those intellectual constructs that disarticulated reality, focusing attention on practise, movement, the making and remaking of reality, or net-work-ing with the complex heterogeneous nature of agency. It envisages practitioners having an epistemology and ontology that is formed through being “out-and-about” in the world, making “translations”.

Through embedding these ideas in the way engineers learn and in the processes that they use, engineering becomes a “putting through”, manoeuvring, dissolving boundaries, always being in action, moving towards sustaining with others, while recognising purpose, congruence and transforming as emergent properties. Through purposive imag(in)ing of different ways of sustainable doing and being integration can occur, reframing across methodology, epistemology, ontology and philosophy.
Sonic blocks : towards an exploratory and expressive tangible interaction
Creators: name: Feltham, Frank
Publisher: name: RMIT University
Year: 2024

description: Tangible User Interaction (TUI) has gathered much momentum over recent years as a way of physically representing and controlling digital information. Tangible User Interfaces privilege the control and action we, as humans, have with our highly developed motor and spatial skills. This physical mode of interaction with computation contrasts significantly with the visual mode of interaction we have with the Graphical User Interface (GUI) of the personal computer. The context for this research inquiry is the design of a TUI, the Sonic Blocks, to encourage exploratory and expressive soundtrack making activities. This thesis gives an account of the design, development and deployment of the Sonic Blocks, with a small group of children in a primary school, to gain an understanding of their unique capabilities to enable a physical and embodied interaction for exploratory and expressive purposes.

Biodegradation of 2, 4, 6-Trinitrotoulene (TNT), Pentaerythritol Tetranitrate (PETN) & Pentolite by environmental microbes
Creators: name: Georgie, Elizabeth
Publisher: name: RMIT University
Year: 2024

description: The nitroaromatic compound 2, 4, 6-trinitrotoluene (TNT) and the nitrate esters glycerol trinitrate (GTN) and pentaerythritol tetranitrate (PETN) are high explosives that have been produced on a massive scale for use in industrial and military applications. Through many years of production and use of these explosives, large quantities of toxic wastes have been generated, which has resulted in extensive contamination of soil and groundwater. These organic nitrate contaminants are highly recalcitrant and not normally found in the environment, thus classifying these compounds as xenobiotics. During this study, 36 bacterial species were isolated from contaminated soil and water that were able to utilize either TNT or PETN as a sole source of nitrogen. These were identified as Arthrobacter sp. (Pa-3, Pb-5, ST12, ST13, ST14, ST17, ST23, ST26), Pseudomonas sp. (ST1, ST2, ST15, ST18, ST19,ST22), Enterobacter sp. (ST3, ST5, ST6, ST8 , ST11), Klebsiella sp. (ST4, ST10, ST16, ST20, ST21, ST28, ST29), Microbacterium sp. (ST7, Pa-4, Pb-6,ST9, ST24, ST25 ST27,ST30), and Achromobacter xylosoxidans (TNT1, TNT2). Six representative isolates were selected from the 36 isolates for further analysis of growth and enzyme activity. The isolates were found to catalyse the NAD(P)H- dependent reductive cleavage/breakdown of GTN and PETN in a manner that was similar to a class of previously described oxidoreuctase flavoproteins. These include Old Yellow Enzyme (OYE), PETN reductase, GTN reductase, xenobiotic reductases A and B and N-ethyl maleimide reductas. This is the first report of nitroaromatic degradation by Achromobacter xylosoxidans as per the author’s knowledge.

The aim of this study was to isolate bacteria able to degrade TNT and PETN and to characterize these bacteria and the enzymes produced by them. Thirty-six bacteria were isolated from contaminated soil and water that were able to utilize either TNT or PETN as a sole source of nitrogen. Identification was based on 16S rRNA gene sequences and biochemical testing.

Studies investigating co-metabolism of the explosives in the presence of Tween-80 was performed. Triton X-100 was also evaluated as co-metabolic substrate. It was demonstrated that the addition of Tween- 80 as a co-substrate assisted in the co-metabolism of explosives and did improve the growth and therefore the degradation of the explosive. However, Triton X-100 did not result in co-metabolism of the explosives since an improvement in growth was not observed.

The information acquired in this study can assist in the further characterization, optimization and production of explosive-degrading enzymes.

Values that you hold: encountering change in an adult community education program in Victoria
Creators: name: Curlewis, Margaret
Publisher: name: RMIT University
Year: 2024

description: This thesis research reports on the Adult Community Education (ACE) sector in the Australian State of Victoria. Although it concentrates on Moreland Adult Education Assoc. (MAE) as a case study, it places MAE in the wider context of ACE in the local area of the Northern Metropolitan region of Melbourne. Although periodically referred to as the 'fourth educational sector' and funded by the same government departments as mainstream post-secondary sectors, ACE has always had a low profile and quasi-educational status due to the extreme variety of its venues, courses and locations, making it difficult to define and market as an entity. This study uses a range of qualitative methodologies suited to historical, educational research to provide a framework based around the initial guiding questions: 'Is ACE becoming TAFE?' and 'Who uses ACE and Why?' MAE was used as a case study because it was created by its local community in 1982 after which it expanded and developed from one-to-one pairs of volunteer tutors and literacy students to being a nationally Registered Training Organisation delivering accredited courses up to Diploma level. This expansion placed great strain on the infrastructure and personnel of the organisation, particularly during the main period of this research (1994 to 2004). Beginning with a review of the ACE sector, the thesis then describes the northern region of the Melbourne suburbs by using the data gained from a survey questionnaire. Further narrowing the research focus, the thesis analyses the development of the organisation over the ten year study period. The second half of the thesis emphasises the people of MAE through 18 interviews by analysing their opinions, life-experiences and perceptions of change to create a sense of their connectedness to the local community and MAE. The primary aims of this thesis are to document an example of the development of an ACE centre and how it managed change during a ten year period. It records a sense of how and why people engaged in the sector and some of their lived-experiences and their responses to changes. Data analysis results in three sets of findings and propositions in the categories of sectoral, organisational and personal. These key findings involve a range of externally applied pressures being brought to bear on both ACE and MAE. This is counteracted by individual resistance to change, creating a tension which threatens MAE's long-term sustainability.

description: The objective of this study is to estimate the cost-effectiveness of KTE-X19 versus standard of care (SoC) in the treatment of patients with relapsed/refractory (R/R) mantle cell lymphoma (MCL) post-Bruton tyrosine kinase inhibitor (BTKi) treatment from a UK healthcare perspective. A three-state partitioned survival model (pre-progression, post-progression and death) with a cycle length of one month was used to extrapolate progression-free and overall survival over a lifetime horizon. Population inputs along with KTE-X19 (brexucabtagene autoleucel) efficacy and safety data were derived from the single-arm trial ZUMA-2 (NCT02601313). The composition of SoC was informed by a literature-based meta-analysis, SoC efficacy data were obtained from the SCHOLAR-2 real-world study. Survival was modelled using standard parametric curves for SoC and a mixture-cure methodology for KTE-X19. It was assumed that patients whose disease had not progressed after five years experienced long-term remission. Costs, resource use and utility, and adverse event disutility inputs were obtained from published literature and publicly available data sources. An annual discount rate of 3.5% was applied to costs and health outcomes. Modelled outcomes for KTE-X19 and SoC included expected life years (LY), quality-adjusted life years (QALY) and total costs. Deterministic and probabilistic sensitivity analyses and scenario analyses were performed. Estimated median survival was 5.96 years for KTE-X19 and 1.38 for SoC. Discounted LYs, QALYs and lifetime costs were 8.27, 5.99 and £385,765 for KTE-X19 versus 1.98, 1.48 and £79,742 for SoC, respectively. The KTE-X19 versus SoC cost per QALY was £67,713 and the cost per LY was £48,645. Influential scenario analyses use alternative KTE-X19 survival curves and discount rates, and shorter time horizons. Considering the survival and quality of life benefits compared to SoC, KTE-X19 for R/R MCL appears as a cost-effective treatment in the real-world UK setting.

Unified model of the Hall effect from insulator to overdoped compounds in cuprate superconductors

description: Measurements of the Hall coefficient in La$_{2-x}$Sr$_x$CuO$_4$, ranging from the undoped ($x = p = 0$) Mott insulator to overdoped compounds, exhibit a temperature dependence that offers insights into their electronic structure. We interpret these results using a model based on the theory of phase-separation (PS) dynamics, which begins at half-filled ($n = 1$) and at a temperature $T_{\rm PS}(p)$, near the pseudogap temperature $T^*(p)$. The $n = 1$ holes have low mobility and provide the modulations of the charge density waves (CDW). As doping increases from $p = 0$, these modulations guide the additional p holes to occupy alternating CDW domains. This charge inhomogeneity may facilitate the formation of localized superconducting amplitudes below the critical onset temperature $T_{\rm c}^{\rm max}(p)$. Using thermal activation expressions, along with quantum tunnelling between the charge domains, we successfully reproduce all Hall coefficient measurements $R_{\rm H}(p,T)$ and highlight the relevant energies of cuprates. The calculations confirm three significant electronic features: the phase-separating role of the pseudogap temperature, the superconducting state achieved through phase coherence,
 and the two types of charge carriers whose energies and mobilities become comparable at $p \approx 0.19$, where
 $T^*(p) \approx T_{\rm c}^{\rm max}(p)$. This results in a crossover from $n = p$ to $n = 1 + p$. These findings, along with the
 $R_{\rm H}(p,T)$ calculations from insulating to overdoped compounds, underscore the critical role of the electronic
 phase separation in the properties of cuprates.

Issues in investment risk : a supply-side and demand-side analysis of the Australian managed fund industry
Creators: name: Hallahan, Terry
Publisher: name: RMIT University
Year: 2024

description: The investment management industry has proven to be a fertile ground for theoretical and empirical research over the past forty years, particularly in relation to the nature and quantification of risk. However, the dominance of the U.S. industry has meant that much of the academic research has focused on the U.S. market. This thesis investigates aspects of investment risk using alternative data to that used in much of the prior published research.

This thesis contains an extensive analysis of aspects of risk related to both the demand side and the supply side of the managed funds market in Australia. Among the demand side characteristics, attitudes towards risk and their impact on asset allocation decisions will be an important determinant of investors' financial well-being, particularly in retirement. Accordingly, the first part of the thesis examines the financial risk tolerance of investors, exploring the relationship between subjective financial risk tolerance and a range of demographic characteristics that are widely used as a basis for heuristically derived estimates of investors' attitudes towards financial risk.

The second part of the thesis contains an analysis of the supply side of the industry, focusing on risk-shifting behavior by investment fund managers. Since the time when performance and risk-shifting behavior of fund managers was first put under the spotlight 40 years ago, it is possible to identify an evolving strand in the research where performance assessment is examined within the framework of the principal-agent literature. One focus that has emerged in this literature is the adaption of the tournament model to the analysis of investment manager behavior, wherein it is hypothesized that fund managers who were interim losers were likely to increase fund volatility in the latter part of the assessment period to a greater extent than interim winners.

description: The objective of this study is to estimate the cost-effectiveness of KTE-X19 versus standard of care (SoC) in the treatment of patients with relapsed/refractory (R/R) mantle cell lymphoma (MCL) post Bruton tyrosine kinase inhibitor (BTKi) treatment from a UK healthcare perspective. Materials & Methods: A three-state partitioned survival model (pre-progression, post-progression and death) with a cycle length of one month was used to extrapolate progression-free and overall survival over a lifetime horizon. Population inputs along with KTE-X19 (brexucabtagene autoleucel) efficacy and safety data were derived from the single-arm trial ZUMA-2 (NCT02601313). The composition of SoC was informed by a literature-based meta-analysis, SoC efficacy data was obtained from the SCHOLAR-2 real-world study. Survival was modelled using standard parametric curves for SoC and a mixture-cure methodology for KTE-X19. It was assumed that patients whose disease had not progressed after five years experienced long-term remission. Costs, resource use and utility, and adverse event disutility inputs were obtained from published literature and publicly available data sources. An annual discount rate of 3.5% was applied to costs and health outcomes. Modelled outcomes for KTE-X19 and SoC included expected life years (LY), quality-adjusted life years (QALY) and total costs. Deterministic and probabilistic sensitivity analyses, and scenario analyses were performed. Estimated median survival was 5.96 years for KTE-X19 and 1.38 for SoC. Discounted LYs, QALYs and lifetime costs were 8.27, 5.99 and £385,765 for KTE-X19 versus 1.98, 1.48 and £79,742 for SoC, respectively. The KTE-X19 versus SoC cost per QALY was £67,713 and the cost per LY was £48,645. Influential scenario analyses uses alternative KTE-X19 survival curves and discount rates, and shorter time horizons. Considering the survival and quality of life benefits compared to SoC, KTE-X19 for R/R MCL appears as a cost-effective treatment in the real-world UK setting.
Single and dual queueing schemes with prioritised traffic scheduling and finite waiting room

description: Analysis of new schemes aimed at improving congestion in communications systems is vital for todays service providers. Many techniques are used to evaluate such schemes be it precisely via mathematics or approximately using simulation.

This thesis introduces a new scheme, the multi priority dual queue (MPDQ). The MPDQ is the combination of two concepts, the dual queue introduced by [Hayes et. al., 1999] and prioritised traffic. The MPDQ is a system with finite waiting room with two queues where traffic upon arrival if finding the first queue full wait in the second queue if there is room. When a space becomes vacant in the first queue, a customer at the front of the second queue enters the back of the first, which is the queue that has the service centre at the front of it. The traffic can be of two or more classes. The analysis of such a system is complex, both analytically using queueing theory and approximately using simulation analysis. Both approaches are taken in this thesis. To begin, the new algorithmic approach used for the MPDQ is applied for the single buffer model. The steady state and waiting time distributions are obtained and later compared to the MPDQ.

Next the performance characteristics are obtained by solving the steady state and waiting time distributions of a two class MPDQ. Preemptive and non-preemptive service disciplines are investigated. Maple is also used to solve the algorithm.

To broaden the application of the MPDQ scheme, computer simulations using Arena are undertaken to extend the application of the scheme (and existing finite queueing models) to situations with more than two priorities, something that is extremely difficult to solve analytically. Using simulation, comparisons are undertaken for the single and dual queue schemes for more than two priorities with a variety of queueing disciplines used including First In First Out (FIFO), Last In First Out (LIFO), High Class First (HCF), and Low Class First (LCF). Network scenarios are also modelled to determine the performance of the MPDQ in this environment.

description: We evaluated the cost-effectiveness of nivolumab in combination with ipilimumab (NIVO + IPI) versus platinum-doublet chemotherapy (PDC) for the first-line treatment of stage IV or recurrent non-small cell lung cancer (NSCLC) from a third-party payer perspective in the United States (US). A partitioned survival model was developed using efficacy, safety, and utility inputs derived from Part 1 of the phase 3 CheckMate 227 trial (NCT02477826) with 37.7-month minimum follow-up for overall survival (OS). OS and progression-free (PF) survival were extrapolated over a 20-year time-horizon using parametric spline-based models selected based on goodness of fit and validated with data from external sources. Duration of treatment Kaplan–Meier curves were used for treatment cost calculations. US-specific costs (2021 dollars) for drug acquisition, administration, and monitoring; disease management (PF and progressed disease health states); end-of-life care; adverse events; and subsequent treatments were derived from publicly available sources. Time-to-death utilities were applied in the base case, whereas treatment-specific progression-based utilities were tested in a scenario analysis. Main outcomes included incremental cost per life-year gained (LYG) and quality-adjusted life-year (QALY). Model uncertainty was assessed through deterministic and probabilistic sensitivity analyses. NIVO + IPI resulted in 1.53 additional life-years, 1.33 additional QALYs, and $142 088 in additional costs compared with PDC. The incremental cost per LYG was $92 651, whereas incremental cost per QALY gained was $106 553. The application of treatment-specific progression-based utilities yielded an incremental cost per QALY gained of $117 076. Probabilistic sensitivity analysis revealed a 98% probability that NIVO + IPI was cost-effective versus PDC at a willingness-to-pay threshold of $150 000 per QALY. NIVO + IPI was estimated to be cost-effective as a first-line treatment for stage IV or recurrent NSCLC in the US, with increased survival and higher cost compared with PDC.

description: We present the first full-wavelength numerical simulations of the electric field generated by cosmic ray impacts into the Moon. Billions of cosmic rays fall onto the Moon every year. Ultra-high energy cosmic ray impacts produce secondary particle cascades within the regolith and subsequent coherent, widebandwidth, linearly-polarized radio pulses by the Askaryan Effect. Observations of the cosmic ray particle shower radio emissions can reveal subsurface structure on the Moon and enable the broad and deep prospecting necessary to confirm or refute the existence of polar ice deposits. Our simulations show that the radio emissions and reflections could reveal ice layers as thin as 10 cm and buried under regolith as deep as 9 m. The Askaryan Effect presents a novel and untapped opportunity for characterizing buried lunar ice at unprecedented depths and spatial scales.
Talk Half Listen To Half: An Energy-Efficient Neighbor Discovery Protocol in Wireless Sensor Networks

description: Due to the combination of constrained power, low duty cycle, and high mobility, neighbor discovery is one of the most challenging problems in wireless sensor networks. Existing discovery designs can be divided into two types: pairwise-based and group-based. The former schemes suffer from high discovery delay, while the latter ones accelerate the discovery process but increase transmission package size or incur too much energy overhead, far from practical. Guided by the Talk More Listen Less (TMLL) principle (published in 2016), in which beacons are not necessarily placed in the wakeup slots, we propose two different versions of a group-based protocol we called Talk Half Listen Half (THLH). For the first time, a group-based protocol uses the Channel Occupancy Rate (COR), one of the fundamental novel components of the TMLL model, for performance improvements, in the same way, Duty Cycle (DC) was used in previous group-based protocols. Both versions of the protocol use low transmission overhead in comparison with previous group-based discoveries. After analyzing pros and cons of each approach, we arrived at the conclusion that both behave the best for networks where the average number of new neighbors per slot (β) is low, a metric that sets the bases for performance comparisons of any current/future work with variable COR usage. We also derived a formula that links this new metric with the worst case avg. COR usage of our proposed protocols. Finally, simulation results show that our protocol can improve the average discovery latency and worst case latency close to 50% given low β values.

Damage analysis of composite pressure vessels using acoustic emission monitoring
Creators: name: Chou, Heng-Yi
Publisher: name: RMIT University

description: Composite pressure vessels (CPVs) fabricated using a metal or plastic liner under a composite structural skin are commonly used for natural gas storage on road vehicles. The composite skin, which is usually made of high strength carbon (or glass) fibre-epoxy composite, is the primary structural component of the vessel. In the past decade, accidents due to catastrophic rupture and explosive failure of CPVs have occurred, which is attributed to a lack of knowledge about the damage tolerance and useful life of these vessels. In part, this is because there is no reliable structural health monitoring (SHM) technique for evaluating the structural integrity of the vessels. The PhD project investigates the feasibility of AE for the SHM of CPVs used on road vehicles.  The PhD project also investigated the suitability of AE to detect damage caused by operational (in-service) factors of CPVs. This includes structural instability analysis, loading scenario analysis, and humidity and temperature effect analysis.  The PhD project numerically analysed the fibre breakage mechanism in unidirectional carbon-epoxy laminates with the consideration of stochastic fibre strength and fibre volume fraction properties, using a finite element approach.  The last part of the PhD project assesses the overall feasibility of AE monitoring for CPVs.  Experimental characterisation of damage in two types of CPVs was performed using acoustic emission.
