description: Multipartite entanglement has been shown to be of particular relevance for a better understanding and exploitation of the dynamics and flow of entanglement in multiparty systems. This calls for analysis aimed at identifying the appropriate processes that guarantee the emergence of multipartite entanglement in a wide range of scenarios. Here we carry on such analysis considering a system of two initially entangled qubits, one of which is let to interact with a third qubit according to an arbitrary unitary evolution. We establish necessary and sufficient conditions on the corresponding Kraus operators, to discern whether the evolved state pertains to either one of the classes of 3-qubit pure states that exhibit some kind of entanglement, namely biseparable, W-, and GHZ- genuine entangled classes. Our results provide a classification of the Kraus operators according to their capacity of producing 3-qubit entanglement, and pave the way for extending the analysis to larger systems and determining the particular interactions that must be implemented in order to create, enhance and distribute entanglement in a specific manner.

description: A procedure was proposed to estimate dermal exposures based on a physiologically-based pharmacokinetic (PBPK) model developed in rats. The study examined vapor concentrations ranging from 500 to 10,000 ppm for dibromomethane and 2,500 to 40,000 ppm for bromochloromethane. These concentrations were reconstructed based on chemical blood levels measured in four hours, with errors varying from 0.0% to 52.0%. The PBPK approach adequately predicted the blood concentrations and helped simulate contaminant transport through the stratum corneum and distribution in the body compartments. The proposed technique made it possible to estimate the skin absorption time (SAT) obtained from acute inhalation toxicity data. An inverse relationship exists between the SAT and exposure concentration. The method can be helpful in toxicology and risk assessment of hazardous volatile organic compounds.

description: Introduced in 1993, the IBM translation models were the first generation Statistical Machine Translation systems. For the IBM Models, only IBM Model 1 is a convex optimization problem, meaning that we can initialize all its probabilistic parameters to uniform values and subsequently converge to a good solution via Expectation Maximization (EM). In this thesis we discuss a mechanism to generate an infinite supply of nontrivial convex relaxations for IBM Model 2 and detail an Exponentiated Subgradient algorithm to solve them. We also detail some interesting relaxations that admit and easy EM algorithm that does not require the tuning of a learning rate. Based on the geometric mean of two variables, this last set of convex models can be seamlessly integrated into the open-source GIZA++ word-alignment library. Finally, we also show other applications of the method, including a more powerful strictly convex IBM Model 1, and a convex HMM surrogate that improves on the performance of the previous convex IBM Model 2 variants.

description: We use an ab-initio approach to design and study a novel two-dimensional material - a planar array of carbon nanotubes separated by an optimal distance defined by the van der Waals interaction. We show that the energy spectrum for an array of quasi-metallic nanotubes is described by a strongly anisotropic hyperbolic dispersion and formulate a model low-energy Hamiltonian for its semi-analytical treatment. Periodic-potential-induced lifting of the valley degeneracy for an array of zigzag narrow-gap nanotubes leads to the band gap collapse. In contrast, the band gap is opened in an array of gapless armchair tubes. These unusual spectra, marked by pronounced van Hove singularities in the low-energy density of states, open the opportunity for interesting physical effects and prospective optoelectronic applications.

description: A crucial step in processing speech audio data for information extraction, topic detection, or browsing/playback is to segment the input into sentence and topic units. Speech segmentation is challenging, since the cues typically present for segmenting text (headers, paragraphs, punctuation) are absent in spoken language. We investigate the use of prosody (information gleaned from the timing and melody of speech) for these tasks. Using decision tree and hidden Markov modeling techniques, we combine prosodic cues with word-based approaches, and evaluate performance on two speech corpora, Broadcast News and Switchboard. Results show that the prosodic model alone performs on par with, or better than, word-based statistical language models -- for both true and automatically recognized words in news speech. The prosodic model achieves comparable performance with significantly less training data, and requires no hand-labeling of prosodic events. Across tasks and corpora, we obtain a significant improvement over word-only models using a probabilistic combination of prosodic and lexical information. Inspection reveals that the prosodic models capture language-independent boundary indicators described in the literature. Finally, cue usage is task and corpus dependent. For example, pause and pitch features are highly informative for segmenting news speech, whereas pause, duration and word-based cues dominate for natural conversation.

description: Phrase structure trees have a hierarchical structure. In many subjects, most notably in Taxonomy such tree structures have been studied using ultrametrics. Here syntactical hierarchical phrase trees are subject to a similar analysis, which is much siompler as the branching structure is more readily discernible and switched. The occurence of hierarchical structure elsewhere in linguistics is mentioned. The phrase tree can be represented by a matrix and the elements of the matrix can be represented by triangles. The height at which branching occurs is not prescribed in previous syntatic models, but it is by using the ultrametric matrix. The ambiguity of which branching height to choose is resolved by postulating that branching occurs at the lowest height available. An ultrametric produces a measure of the complexity of sentences: presumably the complexity of sentence increases as a language is aquired so that this can be tested. A All ultrametric triangles are equilateral or isocles, here it is shown that X structur implies that there are no equilateral triangles. Restricting attention to simple syntax a minium ultrametric distance between lexical categories is calculatex. This ultrametric distance is shown to be different than the matrix obtasined from feaures. It is shown that the definition of c-commabnd can be replaced by an equivalent ultrametric definition. The new definition invokes a minimum distance between nodes and this is more aesthetically satisfing than previouv varieties of definitions. From the new definition of c-command follows a new definition of government.

description: Contaminants in water bodies cause potential health risks for humans and great environmental threats. Therefore, the development and exploration of low-cost, promising adsorbents to remove contaminants from water resources as a sustainable option is one focus of the scientific community. Here, we conducted a critical review regarding the application of pristine and modified/treated biosorbents derived from leaves for the removal of various contaminants. These include potentially toxic cationic and oxyanionic metal ions, radioactive metal ions, rare earth elements, organic cationic and anionic dyes, phosphate, ammonium, and fluoride from water media. Similar to lignocellulose-based biosorbents, leaf-based biosorbents exhibit a low specific surface area and total pore volume but have abundant surface functional groups, high concentrations of light metals, and a high net surface charge density. The maximum adsorption capacity of biosorbents strongly depends on the operation conditions, experiment types, and adsorbate nature. The absorption mechanism of contaminants onto biosorbents is complex; therefore, typical experiments used to identify the primary mechanism of the adsorption of contaminants onto biosorbents were thoroughly discussed. It was concluded that byproduct leaves are renewable, biodegradable, and promising biosorbents which have the potential to be used as a low-cost green alternative to commercial activated carbon for effective removal of various contaminants from the water environment in the real-scale plants.

description: We present accurate QCD predictions for the transverse momentum pT spectrum of electroweak gauge bosons at the LHC for 13 TeV collisions, based on a consistent combination of a NNLO calculation at large pT and N3LL resummation in the small pT limit. The inclusion of higher order corrections leads to substantial changes in the shape of the differential distributions, and the residual perturbative uncertainties are reduced to the few percent level across the whole transverse momentum spectrum. We examine the ratio of pT distributions in charged- and neutral-current Drell-Yan production, and study different prescriptions for the estimate of perturbative uncertainties that rely on different degrees of correlation between these processes. We observe an excellent stability of the ratios with respect to the perturbative order, indicating a strong correlation between the corresponding QCD corrections.

Children with autism spectrum disorders

description: I tested the effects of the absence and presence of Naming on rate of learning when teacher modeling was part of an instructional procedure. A time-lagged multiple probe design across matched pairs of participants was implemented. Eight elementary aged children with autism, ranging in age from 4 to 7 years old, were selected because they lacked Naming at the onset of the study. The dependent variable was the number of instructional trials, or learn units, required to master 6 mathematics curricular objectives: 3 prior to the emergence of Naming, and 3 following the acquisition of Naming. Each instructional session consisted of a teacher model, in which I demonstrated how to solve 2problems while the participant observed, followed by 20 learn units. Learn unit procedures following the teacher-model included positive reinforcement for correct responses and corrective feedback for incorrect responses. The independent variable in the study was the induction of Naming using multiple exemplar instruction (MEI) across listener and speaker responses. Following the emergence of Naming, 3 novel mathematics objectives were taught and rate of learning was measured. The participants' rate of learning under teacher modeling conditions was compared prior to the emergence of Naming, and following the acquisition of Naming. The results of the study showed accelerated learning for all 8 participants under teacher modeling conditions following the acquisition of the Naming capability.

description: The Loschmidt echo measures the sensitivity to perturbations of quantum evolutions. We study its short time decay in classically chaotic systems. Using perturbation theory and throwing out all correlation imposed by the initial state and the perturbation, we show that the characteristic time of this regime is well described by the inverse of the width of the local density of states. This result is illustrated and discussed in a numerical study in a 2-dimensional chaotic billiard system perturbed by various contour deformations and using different types of initial conditions. Moreover, the influence to the short time decay of sub-Planck structures developed by time evolution is also investigated.

description: The Abstract Syntax Description Language (ASDL) is a language for specifying the tree data structures often found in compiler intermediate representations. The ASDL generator reads an ASDL specification and generates code to construct, read, and write instances of the trees specified. Using ASDL permits a compiler to be decomposed into semi-independent components that communicate by reading and writing trees. Each component can be written in a different language, because the ASDL generator can emit code in several languages, and the files written by ASDL-generated code are machine- and language-independent. ASDL is part of the National Compiler Infrastructure project, which seeks to reduce dramatically the overhead of computer systems research by making it much easier to build high-quality compilers. This paper describes dividing lcc, a widely used retargetable C compiler, into two components that communicate via trees defined in ASDL. As the first use of ASDL in a `real' compiler, this experience reveals much about the effort required to retrofit an existing compiler to use ASDL, the overheads involved, and the strengths and weaknesses of ASDL itself and, secondarily, of lcc.

description: We introduce the simplest model to describe parametric interactions in a quadratically nonlinear optical medium with the fundamental harmonic containing two components with (slightly) different carrier frequencies [which is a direct analog of wavelength-division multiplexed (WDM) models, well known in media with cubic nonlinearity]. The model takes a closed form with three different second-harmonic components, and it is formulated in the spatial domain. We demonstrate that the model supports both polychromatic solitons (PCSs), with all the components present in them, and two types of mutually orthogonal simple solitons, both types being stable in a broad parametric region. An essential peculiarity of PCS is that its power is much smaller than that of a simple (usual) soliton (taken at the same values of control parameters), which may be an advantage for experimental generation of PCSs. Collisions between the orthogonal simple solitons are simulated in detail, leading to the conclusion that the collisions are strongly inelastic, converting the simple solitons into polychromatic ones, and generating one or two additional PCSs. A collision velocity at which the inelastic effects are strongest is identified, and it is demonstrated that the collision may be used as a basis to design a simple all-optical XOR logic gate.

A collection of programs, called xfilter, is presented that is capable to find the optimal filter material, the optimal filter thickness, and the optimal scattering angle, for all possible combinations of trace elements, target materials, and tube voltages. The concepts of the calculations are introduced in a general manner and demonstrated with a specific example, the detection of gold K_alpha1 XRF within human tissue. Comparing the calculation results and an EDXRF measurement shows excellent agreement.

description: A stochastic approach to the (generic) mean-field limit in Bose-Einstein Condensation is described and the convergence of the ground state energy as well as of its components are established. For the one-particle process on the path space a total variation convergence result is proved. A strong form of Kac's chaos on path-space for the $k$-particles probability measures are derived from the previous energy convergence by purely probabilistic techniques notably using a simple chain-rule of the relative entropy. The Fisher's information chaos of the fixed-time marginal probability density under the generic mean-field scaling limit and the related entropy chaos result are also deduced.

description: Sustainability has gained growing importance in today’s urban development. In a highly urbanized context, to meet growing population needs, development or equity goals, additional social, economic or environmental benefits are created through urban regeneration projects within a city. This paper explores the concept of urban regeneration and sustainable regeneration, and its assessment methods. A sustainability assessment framework integrating three pillars ⎯ social, environmental and economic aspects will be developed, and the assessment will be performed using the case of Battery Park City, an often-appraised waterfront urban regeneration project in New York City. The processes and results of the development are examined to provide insights on the critical factors and approach to deliver sustainable urban regeneration. In addition, this paper also seeks to contribute to sustainability assessment approaches. As sustainability assessments often focus on one aspect of the three pillars, the developed framework integrating all three pillars could be referenced for scholars that seeks to assess comprehensively. The paper finds that Battery Park City has meaningfully achieved sustainability in terms of deriving social, economic and environmental benefits. Nevertheless, the assessment finds that the Battery Park City could have incorporated sustainability initiative in an earlier stage. It is revealed that tradeoffs between the three aspects and stakeholders are key characters in the result and development processes.

We provide an unqualified downward collapse result completely within the polynomial hierarchy. In particular, we prove that, for k > 2, if $\psigkone = \psigktwo$ then $\sigmak = \pik = \ph$. We extend this to obtain a more general downward collapse result.

description: In this work, we study the rotating magnetic field driven domain wall (DW) motion in antiferromagnetic nanowires, using the micromagnetic simulations of the classical Heisenberg spin model. We show that in low frequency region, the rotating field alone could efficiently drive the DW motion even in the absence of Dzyaloshinskii-Moriya interaction (DMI). In this case, the DW rotates synchronously with the magnetic field, and a stable precession torque is available and drives the DW motion with a steady velocity. In large frequency region, the DW only oscillates around its equilibrium position and cannot propagate. The dependences of the velocity and critical frequency differentiating the two motion modes on several parameters are investigated in details, and the direction of the DW motion can be controlled by modulating the initial phase of the field. Interestingly, a unidirectional DW motion is predicted attributing to the bulk DMI, and the nonzero velocity for high frequency is well explained. Thus, this work does provide useful information for further antiferromagnetic spintronics applications.

description: In this work, with Ni (110) as a model catalyst surface and CO2 as an adsorbate, a performance study of Density Functional Theory methods (functionals) is performed. CO being a possible intermediate in CO2 conversion reactions, binding energies of both, CO2 and CO, are calculated on the Ni surface and are compared with experimental data. OptPBE-vdW functional correctly predicts CO2 binding energy on Ni (−62 kJ/mol), whereas CO binding energy is correctly predicted by the rPBE-vdW functional (−138 kJ/mol). The difference in computed adsorption energies by different functionals is attributed to the calculation of gas phase CO2. Three alternate reaction systems based on a different number of C=O double bonds present in the gas phase molecule are considered to replace CO2. The error in computed adsorption energy is directly proportional to the number of C=O double bonds present in the gas phase molecule. Additionally, both functionals predict similar carbon–oxygen activation barrier (40 kJ/mol) and equivalent C1s shifts for probe species (−2.6 eV for CCH3 and +1.5 eV CO3−), with respect to adsorbed CO2. Thus, by including a correction factor of 28 kJ/mol for the computed CO2 gas phase energy, we suggest using rPBE-vdW functional to investigate CO2 conversion reactions on different metals.
A Framework for Analyzing Stochastic Optimization Algorithms Under Dependence

description: In this dissertation, a theoretical framework based on concentration inequalities for empirical processes is developed to better design iterative optimization algorithms and analyze their convergence properties in the presence of complex dependence between directions and step-sizes. Based on this framework, we proposed a stochastic away-step Frank-Wolfe algorithm and a stochastic pairwise-step Frank-Wolfe algorithm for solving strongly convex problems with polytope constraints and proved that both of those algorithms converge linearly to the optimal solution in expectation and almost surely. Numerical results showed that the proposed algorithms are faster and more stable than most of their competitors. This framework can be applied for designing and analyzing stochastic algorithms with adaptive step-sizes that are based on local curvature for self-concordant optimization problems. Notably, we proposed and analyzed a stochastic BFGS algorithm without line-search, and proved that it converges linearly globally and super-linearly locally using the framework mentioned above. This is the first work that analyzes a fully stochastic BFGS algorithm, which also avoids time consuming or even impossible line-search steps. A third class of problems that the empirical processes framework can be applied to is to study the optimization of compositions of stochastic functions. A multi-level Monte Carlo based unbiased gradient generation method is introduced into stochastic optimization algorithms for minimizing function compositions. Based on this, standard stochastic optimization algorithms can be applied to these problems directly.

description: During this PhD, new organic and organometallic triphenylmethylium dyes were synthesized. Due to their multipolar structure, these compounds have been anticipated to possess strong nonlinear optical (NLO) properties which could be of interest in many fields. These characteristics, and more precisely their two-photon absorption (TPA) properties, make them attractive for the design of high technology materials (microfabrication, imaging, optical devices, etc). However, their multiphoton absorption properties and other related nonlinear optical (NLO) effects have not been thoroughly investigated to date, in spite of their promising potential. In this respect, a family of organic derivatives has been synthesized to confirm their potential as two-photon absorbers, which was established thanks to Z-scan measurements. Organometallic compounds bearing electron-releasing groups such as «Fe(η5-C5Me5)(κ2-dppe)C≡C−» , « Ru(Cl)(κ2-dppe) 2C≡C− » or ethynylferrocene were then synthesized and fully characterized. These organometallic dyes should possess larger TPA cross-sections (and also larger third-order NLO properties) in the NIR range than their organic counterparts. Furthermore, these redox-active metal centers permit access to electro-switchable molecules. In this respect, along with the data already gathered on these derivatives, the study of their cubic NLO properties in their different redox states will now contribute to a better understanding of the underlying electronic phenomena and the role played by the organic and organometallic moieties in such architectures.

Transverse instability and its long-term development for solitary waves of the (2+1)-Boussinesq equation

description: The stability properties of line solitary wave solutions of the (2+1)-dimensional Boussinesq equation with respect to transverse perturbations and their consequences are considered. A geometric condition arising from a multi-symplectic formulation of this equation gives an explicit relation between the parameters for transverse instability when the transverse wavenumber is small. The Evans function is then computed explicitly, giving the eigenvalues for transverse instability for all transverse wavenumbers. To determine the nonlinear and long time implications of transverse instability, numerical simulations are performed using pseudospectral discretization. The numerics confirm the analytic results, and in all cases studied, transverse instability leads to collapse.

The boundedness of the Riesz transform on a metric cone

description: In this thesis we study the boundedness, on L-p spaces, of the Riesz transform associated to a Schroedinger operator with an inverse square potential on a metric cone of dimension greater or equal to 3. The definition of the Riesz transform involves the Laplacian on the cone. However, the cone is not a manifold at the cone tip, so we initially define the Laplacian away from the cone tip, and then consider its self-adjoint extensions. The Friedrichs extension is adopted as the definition of the Laplacian. Using functional calculus, we can express the Riesz transform in terms of the resolvent kernel of the Schroedinger operator. Therefore we construct and at the same time collect information about this resolvent kernel, and then use the information to study the boundedness of the Riesz transform. The two most interesting parts in the construction of the resolvent kernel are the behaviours of the kernel as both the left and right variables approach the cone tip, and as both the left and right variables approach infinity. To study them, a process called the blow-up is performed on the domain of the kernel. We use the b-calculus to study the kernel near the cone tip, while the scattering calculus is used near infinity. The main result of this thesis provides a necessary and sufficient condition on p for the boundedness of the Riesz transform on the space of L-p functions on the metric cone. When the potential function is positive, we have shown that the lower threshold is 1, and the upper threshold is strictly greater than the dimension d; when the potential function is negative, we have shown that the lower threshold is strictly greater than 1, and the upper threshold is strictly between 2 and d. Our results for p less or equal to 2 are contained in the work of J. Assaad, but we use different methods in this thesis. Our boundedness results for p greater or equal to d over 2 for positive inverse square potentials, and for p greater than 2 for negative inverse square potentials, are new.
title: An Examination of Customer Accounting in an Australian Context

Subjects: subject: Customer accounting

description: This thesis reports on a study that examined customer accounting (CA) in Australian companies. The broad aims of the thesis are to develop an understanding of the organisational role played by CA practice and the role accounting plays in providing information about a firm's customer base. Three empirical phases have been undertaken in the study. The first phase involved exploratory interviews with accountants and marketers from a number of Australian firms. The second phase comprised an in-depth case study that involved the development of a segmental customer profitability analysis in a major Australian telecommunications company. The third empirical phase involved the administration of a survey questionnaire to chief accountants and marketing managers from a number of large Australian companies. A number of significant findings are reported and include: (1) A level of CA practice has been observed that is reasonably in line with what was anticipated based on the minimal previous academic interest in this area. (2) There appears to be a potential for further CA development in Australian companies. (3) The interview findings identified 'short-term tactical decisions' and 'focus attention on maximising customer value' as the two most important organisational roles CA may play. (4) CA systems were found to provide important information for marketing resource allocation decisions, customer retention decisions, customer service management decisions and customer pricing decisions. (5) The main barriers to CA implementation identified during the segmental CPA case study and exploratory interviews concerned information technology and data acquisition problems. This finding was supported by the results of the survey questionnaire phase of the study where in addition to these two barriers, 'other competing organisational priorities' was rated highly as an impediment to CA system development. (6) Some support was found for the proposed relationships between CA and the contingent factors of company size, customisation, and organisational structure. (7) Limited support was found for the proposed positive association between CA systems and competition intensity and marketing orientation. (8) No support was found for the proposed relationships between perceived environmental uncertainty, organisational strategy, organisational performance and CA systems. (9) Customisation was the only contingent factor found to have a significant impact upon the potential of CA to aid management.
