description: f(R) gravity is one of the simplest viable modifications to General Relativity: it passes local astrophysical tests, predicts both the early-time cosmic inflation and the late-time cosmic acceleration, and also describes dark matter. In this paper, we probe cosmic magnification on large scales in f(R) gravity, using the well-known Hu-Sawicki model as an example. Our results indicate that at redshifts z < 3, values of the model exponent n > 1 lead to inconsistent behaviour in the evolution of scalar perturbations. Moreover, when relativistic effects are taken into account in the large scale analysis, our results show that as z increases, large-scale changes in the cosmic magnification angular power spectrum owing to integral values of n tend to share a similar pattern, while those of decimal values tend to share another. This feature could be searched for in the experimental data, as a potential "smoking gun" for the given class of gravity models. Furthermore, we found that at z = 1 and lower, relativistic effects lead to a suppression of the cosmic magnification on large scales in f(R) gravity, relative to the concordance model; whereas, at z > 1, relativistic effects lead to a relative boost of the cosmic magnification. In general, relativistic effects enhance the potential of the cosmic magnification as a cosmological probe.

Reactive infiltration: identifying the role of chemical reactions, capillarity, viscosity and gravity

description: A wealth of experimental data indicate that while capillarity controlled infiltration gives an infiltration length that varies with the square root of time, reactive infiltration is characterised by a linear relationship between the two magnitudes. In addition the infiltration rate in the latter is at least two orders of magnitude greater than in the former. This work is addressed to investigate imbibition of a non-wetting, albeit reactive, liquid into a capillary, within the framework of a simple model that includes capillarity effects, viscosity and gravity. The capillary radius is allowed to vary, due to reaction, with both position and time, according to either an interface or a diffusion law. The model allows for capillary closure when reaction kinetics dominates imbibition. At short times, and depending on whether infiltration is capillarity or gravity controlled, the infiltrated length varies either as the square root or linearly with time. This suggest the following track for reactive infiltration: i) In most cases, the contact angle is initially larger than $90^\circ$, ii) after some time, reaction gradually replaces the interface liquid/preform by the liquid/reaction product interface and, concomitantly, the contact angle gets closer to $90^\circ$, iii) beyond that time, gravity triggers infiltration (actually the contact angle does not need to be smaller than $90^\circ$ for the initiation of infiltration due to the metallostatic pressure exerted by the liquid metal on top of the porous preform), iv) thereafter infiltration is controlled by viscosity and gravity, provided that, due to reaction, the contact angle remains close to that at which infiltration was initiated.

Theoretical approaches to urban environmental planning

Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This thesis documents and examines seven histories of environmental and planning thought over the last century, drawing on Yiftachel's (1989) classification of planning theories. It provides evidence that environmental and planning theory over time is moving: away from the understanding of nature as an object; away from the notion of a unitary public interest in planning theory; toward an increasing recognition of uncertainty in environmental decisionmaking; away from instrumental rationality in planning decisionmaking; away from hard determinism in urban design and planning control theory; away from direct pollution controls in environmental policy theory.-- This thesis argues that these changes can be understood in the context of broader philosophical shifts around the issues of being, knowing and acting, involving a reevaluation of the relationships between: subject and object; value and fact; cause and effect.-- It suggests that the changes indicate a shift away from philosophical rationalism in policy theory over time. The thesis concludes that neither the extremes of rationalism or relativism provide a sound theoretical foundation for environmental planning. It suggests that future theoretical development is likely to come from the interaction of theoretical approaches influenced by non-Western cultures, and innovations produced by local cultures adapting existing theories to meet their specific needs.

Gamma-ray Blazars Within the First 2 Billion Years
Creators: name: Large Area Telescope Collaboration
Publisher: name: arXiv
Year: 2017
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: The detection of high-redshift ($z>$3) blazars enables the study of the evolution of the most luminous relativistic jets over cosmic time. More importantly, high-redshift blazars tend to host massive black holes and can be used to constrain the space density of heavy black holes in the early Universe. Here, we report the first detection with the \fermi-Large Area Telescope of five \gm-ray emitting blazars beyond $z=3.1$, more distant than any blazars previously detected in $γ$-rays. Among these five objects, NVSS J151002+570243 is now the most distant known \gm-ray emitting blazar at $z=4.31$. These objects have steeply falling \gm-ray spectral energy distributions (SEDs) and, those that have been observed in X-rays, a very hard X-ray spectrum, both typical of powerful blazars. Their Compton dominance (ratio of the inverse Compton to synchrotron peak luminosities) is also very large ($>20$). All of these properties place these objects among the most extreme members of the blazar population. Their optical spectra and the modeling of their optical-UV SEDs confirm that these objects harbor massive black holes ($M_{\rm BH} \sim 10^{8-10} {\rm M}_{\odot}$). We find that, at $z\approx4$, the space density of $>10^{9} {\rm M}_{\odot}$ black holes hosted in radio-loud and radio-quiet active galactic nuclei are similar, implying that radio-loudness may play a key role in rapid black hole growth in the early Universe.

Slow thermalization and subdiffusion in $U(1)$ conserving Floquet random circuits

description: Random quantum circuits are paradigmatic models of minimally structured and analytically tractable chaotic dynamics. We study a family of Floquet unitary circuits with Haar random $U(1)$ charge conserving dynamics; the minimal such model has nearest-neighbor gates acting on spin 1/2 qubits, and a single layer of even/odd gates repeated periodically in time. We find that this minimal model is not robustly thermalizing at numerically accessible system sizes, and displays slow subdiffusive dynamics for long times. We map out the thermalization dynamics in a broader parameter space of charge conserving circuits, and understand the origin of the slow dynamics in terms of proximate localized and integrable regimes in parameter space. In contrast, we find that small extensions to the minimal model are sufficient to achieve robust thermalization; these include (i) increasing the interaction range to three-site gates (ii) increasing the local Hilbert space dimension by appending an additional unconstrained qubit to the conserved charge on each site, or (iii) using a larger Floquet period comprised of two independent layers of gates. Our results should inform future numerical studies of charge conserving circuits which are relevant for a wide range of topical theoretical questions.

description: The \emph{Diophantine exponent} of an action of a group on a homogeneous space, as defined by Ghosh, Gorodnik, and Nevo, quantifies the complexity of approximating the points of the homogeneous space by the points on an orbit of the group. We show that the Diophantine exponent of the $\mathrm{SL}_n(\mathbb{Z}[1/p])$-action on the generalized upper half-space $\mathrm{SL}_n(\mathbb{R})/\mathrm{SO}_n(\mathbb{R})$, lies in $[1,1+O(1/n)]$, substantially improving upon Ghosh--Gorodnik--Nevo's method which gives the above range to be $[1,n-1]$. We also show that the exponent is \emph{optimal}, i.e.\ equals one, under the assumption of \emph{Sarnak's density hypothesis}. The result, in particular, shows that the optimality of Diophantine exponents can be obtained even when the \emph{temperedness} of the underlying representations, the crucial assumption in Ghosh--Gorodnik--Nevo's work, is not satisfied. The proof uses the spectral decomposition of the homogeneous space and bounds on the local $L^2$-norms of the Eisenstein series.

description: We derive an effective equation and action for the propagation of gravitational waves (GW), encoding the effects of interaction and self-interaction in a time, frequency and polarization dependent effective speed. In terms of an appropriately defined effective metric, the effective action takes the form a massless Klein-Gordon action.
 This effective approach predicts that for theories with matter coupled to the Einstein frame metric the ratio between gravitational and electromagnetic (EM) luminosity distance depends on the effective speed, while for Jordan frame matter coupling it depends on the effective Planck mass. We discuss how the frequency and polarization dependence of the GW-EM distance ratio provides a new test of general relativity and its modifications, and more in general of the interaction of GWs with other fields.

First person narratives and third-wave feminism: raising consciousness or the mother of a guilt trip?

Subjects: Other education not elsewhere classified

description: More than half a century after Betty Friedan’s The Feminine Mystique and forty years after Anne Summers’ Damned Whores and God’s Police raised alarms about the levels of prescription drug use among women in America and Australia, respectively, two high profile Australian journalists and feminists, Lisa Pryor and Mia Freedman, wrote personal columns about juggling work and family, and dealing with mental health issues through consuming anti-depressant and anti-anxiety medication. While second-wave feminists used the personal story form in the practice of consciousness raising, how do these contemporary writers – women who I argue are representative of third-wave feminism – use the personal story form? I argue that the personal story form in these contemporary examples has some parallels with the consciousness raising practice associated with second-wave feminism: it opens up a space for creating empathy and identification, and allows writers and readers to discursively create contradictory and ambiguous maternal subjects. At the same time, I suggest the use of the first person in the mainstream media also exposes feminists to particularly harsh and personal criticisms that appear specifically reserved for women and mothers. I also consider the way the personal voice in these contemporary stories both reinforces post-feminist and neoliberal constructions of women as empowered and responsible for juggling all spheres of life, and tasked with constantly adapting and improving themselves, while – seemingly paradoxically and somewhat contradictorily – simultaneously challenging idealised notions of motherhood through (limited) representations of aberrant mothering.

description: In this Letter we report high-resolution synchrotron X-ray powder diffraction and transmission electron microscope analysis of Mn-substituted LaFeAsO samples, demonstrating that a static incommensurate modulated structure develops across the low-temperature orthorhombic phase, whose modulation wave-vector depends on the Mn content. The incommensurate structural distortion is likely originating from a charge-density-wave instability, a periodic modulation of the density of conduction electrons associated with a modulation of the atomic positions. Our results add a new component in the physics of Fe-based superconductors, indicating that the density wave ordering is charge-driven.

description: Massentierhaltung und Soziale Arbeit? Zwei Bereiche, die auf den ersten Blick keine sichtbaren Zusammenhänge aufweisen. In dieser Forschungsarbeit werden mögliche Anknüpfungspunkte und Verbindungen identifiziert. Es wird aufgezeigt, dass die Massentierhaltung ökologische und soziale Auswirkungen hat, welche die Leitprinzipien der Sozialen Arbeit in besonderer Weise tangieren. Die Soziokulturelle Animation bietet mit ihren Arbeitsprinzipien oder dem Handlungsmodell Potenzial, sich mit dieser Thematik auseinanderzusetzen.

Die vorliegende Bachelorarbeit untersucht die Frage: Wie geht die Soziokulturelle Animation mit der Thematik Massentierhaltung und ihren Auswirkungen um und wo sehen Professionelle Handlungsbedarf? Drei Gruppendiskussionen mit Professionellen aus den Zürcher Gemeinschaftszentren, einer der grössten Anbieterinnen soziokultureller Leistungen in der Stadt Zürich, wurden durchgeführt. Es zeigte sich, dass es an Bewusstsein, Konzepten und Rahmenbedingungen fehlt, um die Herausforderungen der Massentierhaltung angemessen anzugehen. Gleichzeitig wird der Soziokulturellen Animation eine zentrale Rolle im Umgang mit dieser Thematik zugeschrieben. Sie sensibilisiert, fördert die Auseinandersetzung und stösst Veränderungen an. Auf Basis der Erkenntnisse wurden konkrete Handlungsempfehlungen für die Soziokulturelle Animation abgeleitet. Dazu gehört unter anderem der Einbezug der Thematik in die Aus- und Weiterbildung der Professionellen, eine klare Positionierung der Institution sowie die Erweiterung von Angeboten.

Back to epicycles - relativistic Coulomb systems in velocity space
Creators: name: Ben-Ya'acov, Uri
Publisher: name: arXiv
Year: 2017
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: The study of relativistic Coulomb systems in velocity space is prompted by the fact that the study of Newtonian Kepler/Coulomb systems in velocity space, although less familiar than the analytic solutions in ordinary space, provides a much simpler (also more elegant) method. The simplicity and elegance of the velocity-space method derives from the linearity of the velocity equation, which is the unique feature of $1/r$ interactions for Newtonian and relativistic systems alike. The various types of possible trajectories are presented, their properties deduced from the orbits in velocity space, accompanied with illustrations. In particular, it is found that the orbits traversed in the relativistic velocity space (which is hyperbolic ($H^3$) rather than Euclidean) are epicyclic -- circles whose centres also rotate -- thus the title.

description: Tumor segmentation in histopathology images is often complicated by its composition of different histological subtypes and class imbalance. Oversampling subtypes with low prevalence features is not a satisfactory solution since it eventually leads to overfitting. We propose to create synthetic images with semantically-conditioned deep generative networks and to combine subtype-balanced synthetic images with the original dataset to achieve better segmentation performance. We show the suitability of Generative Adversarial Networks (GANs) and especially diffusion models to create realistic images based on subtype-conditioning for the use case of HER2-stained histopathology. Additionally, we show the capability of diffusion models to conditionally inpaint HER2 tumor areas with modified subtypes. Combining the original dataset with the same amount of diffusion-generated images increased the tumor Dice score from 0.833 to 0.854 and almost halved the variance between the HER2 subtype recalls. These results create the basis for more reliable automatic HER2 analysis with lower performance variance between individual HER2 subtypes.

description: We provide an algorithm and a publicly available code to numerically evolve multicomponent Schrödinger-Poisson (SP) systems with a SO($n$) symmetry, including attractive or repulsive self-interactions in addition to gravity. Focusing on the case where the SP system represents the non-relativistic limit of a massive vector field, non-gravitational self-interactions (in particular spin-spin interactions) introduce complexities related to mass and spin conservation which are not present in purely gravitational systems. We address them with an analytical solution for the `kick' step in the algorithm, where we are able to decouple the multicomponent system completely. Equipped with this analytical solution, the full field evolution is second order accurate, preserves spin and mass to machine precision, and is reversible. Our algorithm allows for an expanding universe relevant for cosmology, and the inclusion of external potentials relevant for laboratory settings.

Adventure, schema, supplement: Jacques Derrida and the philosophy of history

description: This thesis studies 'history' in Derrida's Of Grammatology, uncovering a new and productive level of history that impacts historical disciplines (historiography). This is a complex task for two reasons; first on account of the proliferating connotations of 'history'; second, because contemporary historiography and philosophy have largely talked past each other. Historians sometimes create confusion, by ignoring a crucial delineation of levels which deconstruction highlights; alternately, history has frequently been abandoned by philosophers as uninteresting. The first part reconstructs the conceptual network surrounding 'history' in Of Grammatology. Following phenomenological emphasis, Derrida does not address the constituted historical disciplines, but the very historicity that every historical task must presuppose. Derrida seeks to liberate history from concepts that would freeze its very happening. In his reading of Rousseau in particular, Derrida illustrates the metaphysical enchaining of 'history', yet loosening it in that very redescription. I show how this issues in a productive if complex 'diagram', which is implicitly related to multiple concerns of contemporary historiography, as well as occupying a central role within Derrida's own work. In the second part, then, I reconsider some recent historiographical debates from the perspective of this 'diagram'. This perspective forces historiography to confront its own historicity as much as that of its objects - something historians in recent years have been keen to try and do. The 'diagram' is explicated with questions of narrative, meaning, and gender. Through this dialogue, Derrida's emphasis on history is recovered, and historiography is reinvigorated by a renewed philosophical acuity. In the course of this explication and dialogue, Derrida's work appears far different from many of the received representations of a thinker concerned with signs and texts. Derrida is revealed as a thinker of concrete historical situations. His philosophy appears very classical, while at the same time always seeking out dialogue between philosophy and other disciplines.

description: This paper introduces a new spreadsheet tool for adoption by high school or college level physics teachers who use common assessments in a pre-instruction/post-instruction mode to diagnose student learning and teaching effectiveness. The spreadsheet creates a simple matrix that identifies the percentage of students who select each possible pre-/post-test answer combination on each question of the diagnostic exam. Leveraging analysis of the quality of the incorrect answer choices, one can order the answer choices from worst to best (i.e., correct), resulting in "transition matrices" that can provide deeper insight into student learning and the success or failure of the pedagogical approach than traditional analyses that employ dichotomous scoring.

description: Scattering scanning near-field optical microscopy (s-SNOM) is a promising technique for overcoming Abbe diffraction limit and substantially enhancing the spatial resolution in spectroscopic imaging. The s-SNOM works by exposing an atomic force microscope (AFM) tip to an optical electromagnetic (EM) field, while the tip is so close to a dielectric sample that the incident beam lies within the near-field regime and displays nonlinear behaviour. We replace the incident EM field by photons generated by a single photon emitter, and propose a quantum model for the suggested system by employing electric-dipole approximation, image theory, and perturbation theory. Quantum state of scattered photons from the AFM tip is extracted from the proposed model, which contains information about electrical permittivity of the dielectric material beneath the tip. The permittivity of the sample can be extracted through spectroscopic setups. Our proposed scheme has potential applications for high-resolution quantum sensing and metrology, especially for quantum imaging and quantum spectroscopy.

Functional graphs of polynomials and their twist over finite fields

description: Recently, functional graphs, i.e., graphs generated from a polynomial function over Finite Fields Fp, have received renewed interest, due to their applications in Computer Science. In this thesis, we study new functional graphs of degree two generated by a polynomial and its twist. We perform a computational analyses of these functional graphs by developing new algorithms, and optimizing their implementation performances (including multi-threading). Our results show that (i) most graphs are strongly connected or have only two components (including one giant component and one small component of two or three vertices); (ii) every connected component of the graph have many Hamiltonian cycles (growing exponentially with the finite field); (iii) these Hamiltonian cycles can be used to construct balancing binary sequences. Also the Hamiltonian property makes these graphs distinct to well-known random mappings where the expected cycle length is about √p.These experimental results were used to guide several theoretical analysis and then compared with the relevant mathematical proofs.

description: The diagnosis of primary bone tumors is challenging, as the initial complaints are often non-specific. Early detection of bone cancer is crucial for a favorable prognosis. Incidentally, lesions may be found on radiographs obtained for other reasons. However, these early indications are often missed. In this work, we propose an automatic algorithm to detect bone lesions in conventional radiographs to facilitate early diagnosis. Detecting lesions in such radiographs is challenging: first, the prevalence of bone cancer is very low; any method must show high precision to avoid a prohibitive number of false alarms. Second, radiographs taken in health maintenance organizations (HMOs) or emergency departments (EDs) suffer from inherent diversity due to different X-ray machines, technicians and imaging protocols. This diversity poses a major challenge to any automatic analysis method. We propose to train an off-the-shelf object detection algorithm to detect lesions in radiographs. The novelty of our approach stems from a dedicated preprocessing stage that directly addresses the diversity of the data. The preprocessing consists of self-supervised region-of-interest detection using vision transformer (ViT), and a foreground-based histogram equalization for contrast enhancement to relevant regions only. We evaluate our method via a retrospective study that analyzes bone tumors on radiographs acquired from January 2003 to December 2018 under diverse acquisition protocols. Our method obtains 82.43% sensitivity at 1.5% false-positive rate and surpasses existing preprocessing methods. For lesion detection, our method achieves 82.5% accuracy and an IoU of 0.69. The proposed preprocessing method enables to effectively cope with the inherent diversity of radiographs acquired in HMOs and EDs.

description: Hydrodynamic discontinuities in an external potential and incompressible flow are investigated. Using the reaction front as an example in a 2D stream, an overdetermined system of equations is obtained that describes its motion in terms of the surface itself. Assuming that the harmonic flux approaching discontinuity is additional smooth, these equations can be used to determine the motion of this discontinuity without taking into account the influence of the flow behind the front, as well as the entire external flow. It is well known that for vanishingly low viscosity, the integral relation on the boundary (Dirichlet, Neumann problems) connects the tangential and normal components of the velocity. Knowing one of them along the boundary of the discontinuity, one can determine the entire external flow. However, assuming the external flow is smooth, this will also be the case for all derivatives of velocity with respect to coordinates and time. Then a paradox arises, knowing the position of the discontinuity and the velocity data at a point on its surface, it is possible to determine the motion of this discontinuity without taking into account the influence of the flow behind the front, as well as the entire external flow. There is no physical explanation for this mechanism. It is possible that a boundary layer is formed in front of the front, where viscosity plays a significant role and Euler equations are violated. It is argued that the classical idea of the motion of hydrodynamic discontinuities in the smooth, potential and incompressible flow in the external region should be supplemented in this case.

description: Novel adsorbents consisting of ZnFe2O4/Zn5(OH)6(CO3)2 (hydrozincite) nanocomposite materials were studied for efficient As(V) removal from water. Nanocomposites were synthesized by the co-precipitation of Zn and Fe salts in alkaline conditions. Depending on the Zn/Fe molar ratio, a variety of materials was produced with different ZnFe2O4/Zn5(OH)6(CO3)2 contents. The adsorbent’s efficiency for As(V) removal was enhanced proportionally to the percentage of Zn5(OH)6(CO3)2 content. The nanocomposite with 74 ± 7 wt% of Zn5(OH)6(CO3)2 provided a capacity of 18.4 μg As(V)/mg for residual concentration of 10 μg/L (pH 7) which is over twice that of an iron oxy-hydroxide prepared under similar conditions.

description: The observation and imaging of hundreds or thousands of radio sources with the technique of very long baseline interferometry (VLBI) is a computationally intensive task. However, these surveys allow us to conduct statistical investigations of large source samples, and also to discover new phenomena or types of objects. The field of view of these high-resolution VLBI imaging observations is typically a few arcseconds at cm wavelengths. For practical reasons, often a much smaller fraction of the field, the central region is imaged only. With an automated process we imaged the ~1.5-arcsec radius fields around more than 1000 radio sources, and found a variety of extended radio structures. Some of them are yet unknown in the literature.

description: Microservice resilience, the ability of microservices to recover from failures and continue providing reliable and responsive services, is crucial for cloud vendors. However, the current practice relies on manually configured rules specific to a certain microservice system, resulting in labor-intensity and flexibility issues, given the large scale and high dynamics of microservices. A more labor-efficient and versatile solution is desired. Our insight is that resilient deployment can effectively prevent the dissemination of degradation from system performance metrics to user-aware metrics, and the latter directly affects service quality. In other words, failures in a non-resilient deployment can impact both types of metrics, leading to user dissatisfaction. With this in mind, we propose MicroRes, the first versatile resilience profiling framework for microservices via degradation dissemination indexing. MicroRes first injects failures into microservices and collects available monitoring metrics. Then, it ranks the metrics according to their contributions to the overall service degradation. It produces a resilience index by how much the degradation is disseminated from system performance metrics to user-aware metrics. Higher degradation dissemination indicates lower resilience. We evaluate MicroRes on two open-source and one industrial microservice system. The experiments show MicroRes' efficient and effective resilience profiling of microservices. We also showcase MicroRes' practical usage in production.

description: Several active areas of research in novel energy storage technologies, including three-dimensional solid state batteries and passivation coatings for reactive battery electrode components, require conformal solid state electrolytes. We describe an atomic layer deposition (ALD) process for a member of the lithium phosphorus oxynitride (LiPON) family, which is employed as a thin film lithium-conducting solid electrolyte. The reaction between lithium tert-butoxide (LiO$^t$Bu) and diethyl phosphoramidate (DEPA) produces conformal, ionically conductive thin films with a stoichiometry close to Li$_2$PO$_2$N between 250 and 300$^\circ$C. The P/N ratio of the films is always 1, indicative of a particular polymorph of LiPON which closely resembles a polyphosphazene. Films grown at 300$^\circ$C have an ionic conductivity of $6.51\:(\pm0.36)\times10^{-7}$ S/cm at 35$^\circ$C, and are functionally electrochemically stable in the window from 0 to 5.3V vs. Li/Li$^+$. We demonstrate the viability of the ALD-grown electrolyte by integrating it into full solid state batteries, including thin film devices using LiCoO$_2$ as the cathode and Si as the anode operating at up to 1 mA/cm$^2$. The high quality of the ALD growth process allows pinhole-free deposition even on rough crystalline surfaces, and we demonstrate the fabrication and operation of thin film batteries with the thinnest (<100nm) solid state electrolytes yet reported. Finally, we show an additional application of the moderate-temperature ALD process by demonstrating a flexible solid state battery fabricated on a polymer substrate.

The Huli language of Papua New Guinea

Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: This thesis describes the language of the Huli speech community of the Southern Highlands of Papua New Guinea. The first chapter situates the speech community in its historical setting, and refers to previous, mainly non-linguistic, studies. The second chapter situates the commuity in its geographical and 'traditional' setting, recording putative migrations and dialectal variations. The third chapter describes segmental phonology at a level of detail not previously given in accounts of the language, while the fourth chapter presents a tentative exploration of prosodic features. The fifth chapter describes verbs, the sixth adverbials, and the seventh nominals: in each instance there is an emphasis on morphology and morphophonemic processes hitherto unrecorded for Huli. The eighth chapter describes word complexes, and the ninth group complexes, using a systemic-functional approach that establishes a descriptive framework that indicates useful insights into the pragmatics of the language. Chapter ten selects and explores, in varying degrees, semantic features that are typologically interesting, while chapter eleven re-focusses the thesis on sociolinguistic issues. The twelveth chapter presents a dozen texts, which it interprets and comments on in the light of linguistic and sociological descriptions presented previously. The appendices that follow give the data bases for some of the descriptions given in the thesis body. The body of the thesis is concerned with describing the language as it is being created and used by living, real, people. Hence, the language forms at each level are described and interpreted in relation to their functions in creating meaning. This has necessitated presenting in some detail phonological and morphological data that need to be described if the language is to be seen as the growing, changing expression of the living society that uses and creates it.

description: We present a new type of feedback linearization that is tailored for mechanical control systems. We call it a mechanical feedback linearization. Its basic feature is preservation of the mechanical structure of the system. For mechanical systems with a scalar control, we formulate necessary and sufficient conditions that are verifiable using differentiations and algebraic operations only. We illustrate our results with several examples.
