description: Gaia-DR2 has provided an unprecedented number of white dwarf candidates of our Galaxy. In particular, it is estimated that Gaia-DR2 has observed nearly 400,000 of these objects and close to 18,000 up to 100 pc from the Sun. This large quantity of data requires a thorough analysis in order to uncover their main Galactic population properties, in particular the thin and thick disk and halo components. Taking advantage of recent developments in artificial intelligence techniques, we make use of a detailed Random Forest algorithm to analyse an 8-dimensional space (equatorial coordinates, parallax, proper motion components and photometric magnitudes) of accurate data provided by Gaia-DR2 within 100 pc from the Sun. With the aid of a thorough and robust population synthesis code we simulated the different components of the Galactic white dwarf population to optimize the information extracted from the algorithm for disentangling the different population components. The algorithm is first tested in a known simulated sample achieving an accuracy of 85.3%. Our methodology is thoroughly compared to standard methods based on kinematic criteria demonstrating that our algorithm substantially improves previous approaches. Once trained, the algorithm is then applied to the Gaia-DR2 100 pc white dwarf sample, identifying 12,227 thin disk, 1,410 thick disk and 95 halo white dwarf candidates, which represent a proportion of 74:25:1, respectively. Hence, the numerical spatial densities are $(3.6\pm0.4)\times10^{-3}\,{\rm pc^{-3}}$, $(1.2\pm0.4)\times10^{-3}\,{\rm pc^{-3}}$ and $(4.8\pm0.4)\times10^{-5}\,{\rm pc^{-3}}$ for the thin disk, thick disk and halo components, respectively. The populations thus obtained represent the most complete and volume-limited samples to date of the different components of the Galactic white dwarf population.

Winds of change: an archaeology of contact in the Groote Eylandt archipelego, Northern Australia
Creators: name: Clarke, Anne Fiona
Publisher: name: The Australian National University
Year: 1994

description: This thesis presents an archaeological study of contact where an island Aboriginal society in northern Australia experienced first contact with non­ Aboriginal cultural groups in the recent past. The island society is that of the Anindilyakwa-speaking clans of the Groote Eylandt archipelago in the Northern Territory of Australia. The research is based on eleven months of fieldwork conducted on Groote Eylandt over three periods in 1990, 1991 and 1992 and reports on the results of test-excavations carried out at 18 different archaeological sites. I put forward the thesis that changes in resource use and residence patterns can be identified in the archaeological record during the period of Macassan contact, and that there is a trajectory of change leading into the last seventy years of Mission settlement. I present a three part model of resource use and residence patterns encompassing the pre-contact period, Macassan contact and the period of Mission settlement. I further suggest that the changes identified in the archaeological record are indicative of a re-structuring of the cultural landscape as result of contact, first with Macassans and later with missionaries. The analyses of archaeological, ethnographic and archival information presented in this thesis suggest that the influence of Macassan contact on Aboriginal culture was more far reaching than has previously been considered. In this thesis the relationship between Aboriginal society of Groote Eylandt and outsiders is analysed as a process of interaction and mediation. The concept of mediation provides for an active and negotiated relationship between Macassans and Aboriginal people, and Europeans and Aboriginal people. The concept of mediation is also used to describe and analyse the way in which the direction of this project was the outcome of negotiations between myself and the Aboriginal community. The process of mediation thus establishes a conceptual link between contact in the past, and contact between myself and the Aboriginal community in the present. There are several inter-connected components to this thesis. The primary aim of the research is to identify and explain changes and continuities in resource use and residence patterns across a time span of 25OO years, a period which encompasses contact with Macassans and colonisation by Missionaries. A secondary concern of the thesis is a reflexive exploration of the social and personal context in which the research took place. Although this is not the main focus of this thesis, it is, however, inextricably interwoven into the fabric of the archaeology because the act of doing fieldwork within an Aboriginal cultural landscape fundamentally transformed both the research and myself, the researcher. There is a subsidiary outcome of the thesis. The fieldwork has provided the first descriptions of the late Holocene archaeology of Groote Eylandt.

Post-Lapita Fiji: cultural transformation in the mid-sequence
Creators: name: Clark, Geoffrey R.
Publisher: name: The Australian National University
Year: 1999

description: This dissertation examines the little known cultural changes that occurred In Fiji during the 1500 years between the end of Lapita and the late prehistoric era - a period of time termed here the 'mid-sequence’. During this interval the relatively homogeneous proto Polynesian Lapita culture of Fiji developed a complex pattern of human variation which differentiated It from West Polynesia and linked Fiji with the greater cultural diversity found in Melanesia. This thesis charts, through in-depth analysis of ceramics gathered primarily from two field excavations (Navatu 17A and Ugaga Island) and one museum collection (Karobo VL H3/1),the Importance of Internal processes as drivers for Fiji's cultural development. While external contacts clearly did take place, the ceramic evidence Indicates it did not dominate mid- sequence events In Fiji. It suggests that social contact between communities within the archipelago was likely to have reached its low point earlier than previously thought-between 2300 and 1900 BP, or about 400 years after the demise of Lapita. It further finds that after a relatively short period of social Isolation, the mid-sequence was a time, largely, of dynamic regional networks - indicating that a cohesive archipelago-focused community was developing. Such regional networks were likely to have formed the basis of the complex and formal social structures of the late prehistoric period In Fiji, and of the Inter-archipelago networks that linked Fiji with Its Pacific neighbours. Finally, it suggests that the differentiation of Fiji from other archipelagoes began soon after the end of Lapita, and that the type of mid-sequence interaction in Fiji was closer to that reconstructed for the post-Lapita period of Tonga and Samoa than the kind of localised interaction found in Vanuatu and New Caledonia.

Matrix approach to synchronizing automata
Creators: name: Trahtman, A. N.
Publisher: name: arXiv
Year: 2019
Subjects: subject: Formal Languages and Automata Theory (cs.FL)
subject: FOS: Computer and information sciences

description: A word $w$ of letters on edges of underlying graph $Γ$ of deterministic finite automaton (DFA) is called synchronizing if $w$ sends all states of the automaton to a unique state. J. Černy discovered in 1964 a sequence of $n$-state complete DFA possessing a minimal synchronizing word of length $(n-1)^2$. The hypothesis, well known today as Černy conjecture, claims that $(n-1)^2$ is a precise upper bound on the length of such a word over alphabet $Σ$ of letters on edges of $Γ$ for every complete $n$-state DFA. The hypothesis was formulated distinctly in 1966 by Starke. A special classes of matrices induced by words in the alphabet of labels on edges of the underlying graph of DFA are used for the study of synchronizing automata.

Politics, tradition and structural Change: Fijian fertility in the twentieth century
Creators: name: Chung, Margaret
Publisher: name: The Australian National University
Year: 1991

description: The model of demographic transition maintains the currency of ideas of social evolution in demographic theory, with tradition and modernity considered to be inversely related. Together with local values regarding tradition, this construction of explanation portrays Fijian women as traditional people clinging for socio-economic and political reasons to a culturally-patterned pronatalism. Yet, in Fiji, there is little knowledge of how social changes encountered by people of any ethnic community are related to fertility behaviour. This thesis engages a range of scales and a time depth of three generations to examine links between social, economic and political changes in Fiji over the twentieth century and fertility changes in the indigenous Fijian population. It traces the development of wider opportunities for women and their access to resources over the twentieth century, examines the nature of gender relations and kinship, and considers the impact of these changes upon the lives of women and their fertility behaviour. A central theme concerns the role of the state in demographic change. The argument is that the demographic behaviour of people is powerfully influenced by institutional incentives or constraints which encourage or inhibit certain actions, often without intention. Just as there may be explicit policies to influence demographic behaviour, so there are 'hidden' policies set in motion by existing state activities and, more broadly, the general style of local development. Structures of opportunity often originate in state policies and operate indirectly on fertility behaviour through their impact on individual life-courses. As the opportunity structure becomes more diverse, so too does the fertility behaviour of a community. The variance in life experiences that increases through this century demonstrates the selective effects of social institutions upon individual lives. Here, history is recounted on two levels: that of the Fiji state, with particular reference to the pattern of governance and the formation of neotraditiona1 society; and that of the lives of ordinary people. Behind these histories lies a consideration of the mental constructs of social science which pattern our interpretation of events. Internationally, understanding of the politico-economic nature of community reproduction and the politicized nature of demographic processes has been promoted by more detailed histories of local communities. Integral to such research has been the identification of new information sources and the formulation of methods to exploit these. To reconstruct the history of this community and of individuals in it, I drew upon and amalgamated two rich but unreliable sources of information: the memories of community members and a genealogical register of communal land-owners, the Vola ni Kawa Bula.

description: Laser capabilities to eliminate contaminants and deterioration products from the surface of material without altering the material surface makes this technology an ultimate cleaning solution for archaeological material conservation. Among the other main parameters that work for controlled laser cleaning, pulse repetition rate plays an important role [1][2]; keeping pulse energy below the plasma formation threshold, sub-nanosecond high-repetition rate could act to power up the efficiency of archaeological material cleaning by n-IR laser. Though some parameters are governed by fluence as well as by the technically fixed data of built-in laser equipment for laser cleaning intervention, the ablation threshold of the materials could be deduced after irradiation with a series of laser pulses [3]. Hence, materials thermal properties introduce structural defects even if the absorbed laser energy is below the damage threshold. This paper proposes new possibilities of using pulse mode n-IR Laser with sub-nanosecond high-repetition-rate which could offer more potentials for minimal interventions of Archaeological material conservation. The work includes significant Pleistocene bones and Neogene flints from Sierra de Atapuerca case study to assess the proposed laser parameters; results will be clearly outlined to demonstrate the usefulness of the high- repetition-rate lasers with low pulse energy in application and open to progress more effective, operative and safer laser cleaning profiles.

description: The body centered tetragonal structure of Sr_2RuO_4 gives rise to umklapp scattering enhanced inter-plane pair correlations in the d_{yz} and d_{zx} orbitals. Based on symmetry arguments, Hund's rule coupling, and a bosonized description of the in-plane electron correlations the superconducting order parameter is found to be a orbital-singlet spin-triplet with two spatial components. The spatial anisotropy is 7%. The different components of the order parameter give rise to two-dimensional gapless fluctuations. The phase transition is of third order. The temperature dependence of the pair density, specific heat, NQR, Knight shift, and susceptibility are in agreement with experimental results.

The temporal overfitting problem with applications in wind power curve modeling

description: This paper is concerned with a nonparametric regression problem in which the input variables and the errors are autocorrelated in time. The motivation for the research stems from modeling wind power curves. Using existing model selection methods, like cross validation, results in model overfitting in presence of temporal autocorrelation. This phenomenon is referred to as temporal overfitting, which causes loss of performance while predicting responses for a time domain different from the training time domain. We propose a Gaussian process (GP)-based method to tackle the temporal overfitting problem. Our model is partitioned into two parts—a time-invariant component and a time-varying component, each of which is modeled through a GP. We modify the inference method to a thinning-based strategy, an idea borrowed from Markov chain Monte Carlo sampling, to overcome temporal overfitting and estimate the time-invariant component. We extensively compare our proposed method with both existing power curve models and available ideas for handling temporal overfitting on real wind turbine datasets. Our approach yields significant improvement when predicting response for a time period different from the training time period. Supplementary material and computer code for this article is available online.

description: This research is concerned with conversation—the most complex and vital way language can be used to connect with community. Language, as an empowering element of human, social and cultural agency, is used to organise thinking and to express thought. Language and communication are often considered as mutually inclusive but this is only half the story. Language has two representations: the linguistic, where units of meaning can be generated and shaped according to social conventions; and the non-linguistic, where bodily movements are used to augment or to be an alternative to linguistically formed language. Guided by dynamic systems theory this research answers the primary research question: ‘What strategies do adult communication assistants use when they interact with someone who has Down syndrome, Rett syndrome or cerebral palsy. These genotypes have been specifically chosen because of their association with particular augmentative methods of communication. Therefore, when examining the conversational strategies used by their communication assistants it is envisaged that a diverse range of language methods and tools will be evidenced, such as speech approximations, key word signing, eye gaze, pointing, and speech-generating devices. In addition, six secondary research questions are answered to provide a clearer understanding of the nature of communication assistants and conversation in the augmentative and alternative communication (AAC) context.

description: We investigate the performance of two machine learning algorithms in the context of anti-spam filtering. The increasing volume of unsolicited bulk e-mail (spam) has generated a need for reliable anti-spam filters. Filters of this type have so far been based mostly on keyword patterns that are constructed by hand and perform poorly. The Naive Bayesian classifier has recently been suggested as an effective method to construct automatically anti-spam filters with superior performance. We investigate thoroughly the performance of the Naive Bayesian filter on a publicly available corpus, contributing towards standard benchmarks. At the same time, we compare the performance of the Naive Bayesian filter to an alternative memory-based learning approach, after introducing suitable cost-sensitive evaluation measures. Both methods achieve very accurate spam filtering, outperforming clearly the keyword-based filter of a widely used e-mail reader.

description: Sensing the world around us is fundamental to modern life. Since the advent of micro-scale, batch-fabricated sensors, we now interact with sensors in an array of consumer electronics, such as smart phones, watches and other wearables, and we rely on sensors for control and monitoring of complex systems, such as cars, jet engines, fossil fuel and renewable power generation as well as industrial processes. Sensors enable the internet-of-things; they are defining what we can measure within our data driven society. As the number of sensors produced increases, we seek to further innovate and scale sensor technologies with the key economic drivers being improved sensor performance and functionality, better system integration and characterization, reduced sensor size and power consumption, improved manufacturability and reduced cost.
      This thesis presents a brief history and overview of state-of-the-art microelectromechanical systems (MEMS) strain, pressure and acceleration sensors followed by new advancements in dynamic pressure measurements and the characterization of dynamic pressure transducers. Accurate dynamic pressure measurement is vital to proper system design and operation, such as active control and system health monitoring of gas turbines. This work presents several dynamic pressure characterization techniques in gases and liquids. Applying these characterization methodologies, the frequency response of pressure transducers and pressure measurement systems are experimentally determined. These tools along with several analytical modeling techniques are further employed in the development of static pressure compensation for differential pressure transducers, low-pass filtering to prevent aliasing and real-time, analog active frequency response correction for aerodynamically-driven resonances in pressure transducers.
      In addition to these advancements, this work explores nano-scale strain, pressure and acceleration sensors employing 2D materials. The 2D materials used within these innovative transducers include graphene and molybdenum disulfide (MoS2). Detailed electrical and mechanical characterization of both materials are presented with unique test methodologies. This work provides the design, modeling and fabrication processes for these 2D material-based sensors. Application specific packaging and test methodologies are included. This thesis further compares commercially available MEMS sensors and 2D material-based sensors.

description: Road accidents are an important issue of our modern societies, responsible for millions of deaths and injuries every year in the world. In Quebec only, in 2018, road accidents are responsible for 359 deaths and 33 thousands of injuries. In this paper, we show how one can leverage open datasets of a city like Montreal, Canada, to create high-resolution accident prediction models, using big data analytics. Compared to other studies in road accident prediction, we have a much higher prediction resolution, i.e., our models predict the occurrence of an accident within an hour, on road segments defined by intersections. Such models could be used in the context of road accident prevention, but also to identify key factors that can lead to a road accident, and consequently, help elaborate new policies. We tested various machine learning methods to deal with the severe class imbalance inherent to accident prediction problems. In particular, we implemented the Balanced Random Forest algorithm, a variant of the Random Forest machine learning algorithm in Apache Spark. Interestingly, we found that in our case, Balanced Random Forest does not perform significantly better than Random Forest. Experimental results show that 85% of road vehicle collisions are detected by our model with a false positive rate of 13%. The examples identified as positive are likely to correspond to high-risk situations. In addition, we identify the most important predictors of vehicle collisions for the area of Montreal: the count of accidents on the same road segment during previous years, the temperature, the day of the year, the hour and the visibility.

description: In this paper we explore the effect of the generalized uncertainty principle and modified dispersion relation to compute Hawking radiation from a rotating acoustic black hole in the tunneling formalism by using the Wentzel-Kramers-Brillouin (WKB) approximation applied to the Hamilton-Jacobi method. The starting point is to consider the planar acoustic black hole metric found in a Lorentz-violating Abelian Higgs model. In our analyzes we investigate quantum corrections for the Hawking temperature and entropy. A logarithmic correction and an extra term that depends on a conserved charge were obtained. We also have found that the changing in the Hawking temperature ${\cal T}_H$ for a dispersive medium due to a Lorentz-violating background accounts for supersonic velocities in the general form $(v_g-v_p)/v_p = Δ{\cal T}_H/{\cal T}_H\sim10^{-5}$ in Bose-Einstein-Condensate (BEC) systems.

description: A Dielectric Barrier Discharge (DBD) plasma jet in a four electrodes configuration was investigated in order to improve the discharge parameters, such as, plasma power and rotational and vibrational temperatures of molecular species in the plasma plume. The improvement attempts were made by introducing an auxiliary floating electrode in a form of a metallic pin inside the DBD device. That piece was placed near the bottom of the main device, centered in relation to the four powered electrodes, which were covered with a dielectric material. By using metallic pins with different lengths, it was observed that there were considerable variations of the plasma parameters as a function of the pin length. Two carrier gases were tested: argon and helium. With helium as the working gas, it was found that there is an optimal pin length that maximizes the plasma power and its vibrational temperature. In addition, it was verified that for the pin of optimum length the relative intensity of light emissions from OH and NO species achieved higher values than in other conditions studied.

On a conjecture of Bennewitz, and the behaviour of the Titchmarsh-Weyl matrix near a pole

description: For any real limit-$n$ $2n$th-order selfadjoint linear differential expression on $[0,\infty)$, Titchmarsh- Weyl matrices $M(λ)$ can be defined. Two matrices of particu lar interest are the matrices $M_D(λ)$ and $M_N(λ)$ assoc iated respectively with Dirichlet and Neumann boundary conditions at $x=0$. These satisfy $M_D(λ) = -M_{N}(λ)^{-1}$. It is known that when these matrices have poles (which can only lie on the real axis) the existence of valid HELP inequalities depends on their behaviour in the neighbourhood of these poles. We prove a conjecture of Bennewitz and use it, together with a new algorithm for computing the Laurent expansion of a Titchmarsh-Weyl matrix in the neighbourhood of a pole, to investigate the existence of HELP inequalities for a number of differential equations which have so far proved awkward to analyse

description: The next generation wireless communication systems require ubiquitous high-throughput mobile connectivity under a range of challenging network settings (urban versus rural, high device density, mobility, etc). To improve the performance of the system, the physical layer design is of great importance. The previous research on improving the physical layer properties includes: a) highly directional transmissions that can enhance the throughput and spatial reuse; b) enhanced MIMO that can eliminate
contention, enabling linear increase of capacity with number of antennas; c) mmWave technologies which operate on GHz bandwidth to over substantially higher throughput; d) better cooperative spectrum sharing with cognitive radios; e) better multiple access method which can mitigate multiuser interference and allow more multi-users.
      This dissertation addresses several techniques in the physical layer design of the next generation wireless communication systems. In chapter two, an orthogonal frequency division with code division multiple access (OFDM-CDMA) systems is proposed and a polyphase code is used to improve multiple access performance and make the OFDM signal satisfy the peak to average ratio (PAPR) constraint. Chapter three studies the I/Q imbalance for direct down converter. For wideband transmitter and receiver that use direct conversion for I/Q sampling, the I/Q imbalance becomes a critical issue. With higher I/Q imbalance, there will be higher degradation in quadrature amplitude modulation, which degrades the throughput tremendously. Chapter four investigate a problem of spectrum sharing for cognitive wideband communication. An energy-efficient sub-Nyquist sampling algorithm is developed for optimal sampling and spectrum sensing. In chapter ve, we study the channel estimation of millimeter wave full-dimensional MIMO communication. The problem is formulated as an atomic-norm minimization problem and algorithms are derived for the channel estimation in different situations.
      In this thesis, mathematical optimization is applied as the main approach to analyze and solve the problems in the physical layer of wireless communication so that the high-throughput is achieved. The algorithms are derived along with the theoretical analysis, which are validated with numerical results.
