Acoustic power distribution techniques for wireless sensor networks
Creators: name: Pandiyan, Akshayaa
Publisher: name: Imperial College London
Year: 2022

description: Recent advancements in wireless power transfer technologies can solve several residual problems concerning the maintenance of wireless sensor networks. Among these, air-based acoustic systems are still less exploited, with considerable potential for powering sensor nodes. This thesis aims to understand the significant parameters for acoustic power transfer in air, comprehend the losses, and quantify the limitations in terms of distance, alignment, frequency, and power transfer efficiency. This research outlines the basic concepts and equations overlooking sound wave propagation, system losses, and safety regulations to understand the prospects and limitations of acoustic power transfer. First, a theoretical model was established to define the diffraction and attenuation losses in the system. Different off-the-shelf transducers were experimentally investigated, showing that the FUS-40E transducer is most appropriate for this work. Subsequently, different load-matching techniques are analysed to identify the optimum method to deliver power. The analytical results were experimentally validated, and complex impedance matching increased the bandwidth from 1.5 𝑘𝐻𝑧 to 4 𝑘𝐻𝑧 and the power transfer efficiency from 0.02% to 0.43%. Subsequently, a detailed 3D profiling of the acoustic system in the far-field region was provided, analysing the receiver sensitivity to disturbances in separation distance, receiver orientation and alignment. The measured effects of misalignment between the transducers are provided as a design graph, correlating the output power as a function of separation distance, offset, loading methods and operating frequency. Finally, a two-stage wireless power network is designed, where energy packets are inductively delivered to a cluster of nodes by a recharge vehicle and later acoustically distributed to devices within the cluster. A novel dynamic recharge scheduling algorithm that combines weighted genetic clustering with nearest neighbour search is developed to jointly minimise vehicle travel distance and power transfer losses. The efficacy and performance of the algorithm are evaluated in simulation using experimentally derived traces that presented 90% throughput for large, dense networks.

description: The goal of this research is to obtain initial estimates of the prevalence of each of four types of motor speech disorders in children with idiopathic Speech Delay (SD) and to use findings to estimate the population-based prevalence of each disorder. Analyses were completed on audio-recorded conversational speech samples from 415 children recruited for research in idiopathic SD in six USA cities during the past three decades. The speech and motor speech status of each participant was cross-classified using standardized measures in the finalized version of the Speech Disorders Classification System described in the Supplement. Population-based prevalence estimates for the four motor speech disorders were calculated from epidemiological studies of SD conducted in Australia, England, and the USA. A total of 82.2% of the 415 participants with SD met criteria for No Motor Speech Disorder at assessment, 12% met criteria for Speech Motor Delay, 3.4% met criteria for Childhood Dysarthria, 2.4% met criteria for Childhood Apraxia of Speech, and 0% met criteria for concurrent Childhood Dysarthria and Childhood Apraxia of Speech. The estimated population-based prevalence of each of the first three motor speech disorders at 4 to 8 years of age were Speech Motor Delay: 4 children per 1,000; Childhood Dysarthria: 1 child per 1,000; and Childhood Apraxia of Speech: 1 child per 1,000. The latter finding cross-validates a prior prevalence estimate for Childhood Apraxia of Speech of 1–2 children per 1,000. Findings are interpreted to indicate a substantial prevalence of motor speech disorders in children with idiopathic SD.

Descriptive Analysis of Patient Sexual Identity and Trust in the Doctor-Patient Relationship
Creators: name: Couch, Claire
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Previous research has identified a strong link between patients’ social characteristics and health care disparities, and attributed it largely to distrust within the doctor-patient relationship.  However, this research has focused almost exclusively on patients’ race and gender, while ignoring other aspects of their identity that may also influence the clinical encounter, such as sexual identity.  Even less research has focused on whether sexual identity could affect trust in the doctor-patient relationship and, specifically, whether sexual minorities feel less trust in their physicians than individuals who identify as heterosexual.  To fill this gap, I assessed the influence of patients’ sexual identity on trust in their physicians by using data on a sample of 676 participants in the HIV Cost and Services Utilization Study (HCSUS) and bivariate descriptive statistics.  I found no significant relationship between patients’ sexual identity and their level of trust but low levels of trust among the sample overall.  These results suggest that patient sexual identity may not be a key determinant of patient trust, but this relationship should be re-assessed using inferential statistics on data from a larger, nationally representative dataset.

description: Graphene has attracted significant interest both for exploring fundamental science and for a wide range of technological applications. Chemical vapor deposition (CVD) is currently the only working approach to grow graphene at wafer scale, which is required for industrial applications. Unfortunately, CVD graphene is intrinsically polycrystalline, with pristine graphene grains stitched together by disordered grain boundaries, which can be either a blessing or a curse. On the one hand, grain boundaries are expected to degrade the electrical and mechanical properties of polycrystalline graphene, rendering the material undesirable for many applications. On the other hand, they exhibit an increased chemical reactivity, suggesting their potential application to sensing or as templates for synthesis of one-dimensional materials. Therefore, it is important to gain a deeper understanding of the structure and properties of graphene grain boundaries. Here, we review experimental progress on identification and electrical and chemical characterization of graphene grain boundaries. We use numerical simulations and transport measurements to demonstrate that electrical properties and chemical modification of graphene grain boundaries are strongly correlated. This not only provides guidelines for the improvement of graphene devices, but also opens a new research area of engineering graphene grain boundaries for highly sensitive electrobiochemical devices.

An Evaluation of Listener Comprehension Indecision and Cognitive Effort When Unresolvable Ambiguity Leads to Miscommunication

description: Miscommunication is pervasive in conversational interactions, having short- and long-range impacts on interpersonal communication. The evaluation of the social and cognitive underpinnings of miscommunication have received relatively less attention. Here we report two experiments investigating how a listener’s cognitive effort and decision-making processes were affected by a speaker’s use of ambiguity that led to a miscommunication. Both Experiments 1 and 2 found that an environmental cue that made a miscommunication more or less salient impacted listener language processing effort. Moreover, findings from Experiment 2 indicated that listeners may develop different processing heuristics dependent upon the speaker’s use of ambiguity that led to miscommunication, exerting a significant impact on cognition and decision-making. For instance, we found that perspective taking effort and decision-making complexity metrics predict language processing effort, indicating that instances of miscommunication produced cognitive consequences of indecision, thinking, and cognitive pull. Together, these results indicate that listeners behave both reciprocally and adaptively when miscommunications occur, but the way they respond is largely dependent upon the type of ambiguity and how often it is produced by the speaker.

description: We derive two versions of Clausius inequality for open discrete systems, one formulated for the non-equilibrium system itself using contact quantities, the other one using equilibrium quantities belongs to the system's environment. Consequently, Bhalekar's conjecture that there is no Clausius inequality for open systems is disproved.

Exploring Interpolation Techniques in Enumerative Geometry

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: In this paper we examine the invariant subsets A of a vector space V , when we
act by a group, G. Gathering some of the information about A in the equivariant
cohomology ring H*G(V) is an important area of study in enumerative geometry.
The descriptions we seek to find for an invariant subspace satisfies certain universal
properties. A notable example of this is given a vector bundle with fiber V and
structure group G over a compact manifold M looking at some cohomological data
for A-points of a section can be done in the equivariant cohomology ring instead of
the cohomology ring of M. The fundamental cohomology class and Segre-Schwartz-
MacPherson class are two such objects that are the same in both cohomology rings.
Since these classes are universal in the above sense, we expect that it is very
difficult to determine the fundamental class and the Chern-Schwartz-MacPherson
class. However, it is possible in certain situations.
In this paper we find the fundamental class and the CSM/SSM classes in the
equivariant cohomology rings for two separate groups actions. Before we make our
way through calculations, we give some intuitive definition of what these classes are.
The basis for the computations we do is from interpolation characterizations of the
CSM class and the fundamental classes, which are stated in a way applicable to our
situation. We then work through the computation one of these for two seperate group
actions.
The culmination of the first section is the statement and the proof of a well-known
result called the Porteous identity. The second section ends with some conjectures
based on the lower-dimensional results.

description: Als ergänzende Komponente eines Prüfstandes für PTCA-Katheter (Herzkranzgefäßmodell, [1], [2]) wurde unter Verwendung eines Zweiachs-Lasermeßkopfes ODAC 15XY der Fa. Zumbach eine Durchmesserprüfvorrichtung für Katheterballons entwickelt. Mit ihr läßt sich ein wesentliches Kathetermerkmal, der einem definierten Innendruck zugeordnete Durchmesser des Ballons, untersuchen. Der Ballondurchmesser kann zur Beurteilung der Balloncompliance (dV/dp) herangezogen werden, weil die in die Volumenänderung weiterhin eingehende Längenänderung des Ballons für seine Anwendung im Koronargefäß nur eine untergeordnete Bedeutung besitzt. Eine Variation des verwendeten Inflationsdruckes innerhalb des zulässigen Bereichs ermöglicht es dem Anwender das Dilatationsergebnis an die Situation während der Intervention anzupassen. Zu diesem Zweck werden durch die Hersteller Tabellen mitgeliefert, die eine Zuordnung Ballondruck/Außendurchmesser vornehmen. Diese Darstellung trifft jedoch nur einen Teil des tatsächlichen Ballonverhaltens. Die verwendeten Kunststoffe ( PE, PET, oder PA) weisen während der Dilatation ein Kriechverhalten auf. Es führt dazu, daß bei konstantem Innendruck innerhalb der üblichen Dilatationszeit von 30s bis 60s der Ballondurchmesser langsam zunimmt. Ziel dieses Beitrages sind die Vorstellung des angewandten Untersuchungsverfahrens und der Nachweis einer Zeitabhängigkeit der erreichten Ballondurchmesser. Der Stichprobenumfang der bisher getesten Katheter läßt zur Zeit noch keine verallgemeinernden Schlüsse auf Unterschiede zwischen PTCA-Kathetertypen zu.

description: We compute the spectral statistics of the sum H of two independent complex Wishart matrices, each of which is correlated with a different covariance matrix. Random matrix theory enjoys many applications including sums and products of random matrices. Typically ensembles with correlations among the matrix elements are much more difficult to solve. Using a combination of supersymmetry, superbosonisation and bi-orthogonal functions we are able to determine all spectral k-point density correlation functions of H for arbitrary matrix size N. In the half-degenerate case, when one of the covariance matrices is proportional to the identity, the recent results by Kumar for the joint eigenvalue distribution of H serve as our starting point. In this case the ensemble has a bi-orthogonal structure and we explicitly determine its kernel, providing its exact solution for finite N. The kernel follows from computing the expectation value of a single characteristic polynomial. In the general non-degenerate case the generating function for the k-point resolvent is determined from a supersymmetric evaluation of the expectation value of k ratios of characteristic polynomials. Numerical simulations illustrate our findings for the spectral density at finite N and we also give indications how to do the asymptotic large-N analysis.

description: We study mathematical and computational models for computing the deformation of fiber-reinforced cross-plied laminates due to external forces. This requires an understanding of both micro-structural effects and different sources of uncertainty in the problem. We first show that the uncertainties in the problem are of both statistical (aleatoric) and systematic (epistemic) types and that current multiscale stochastic models, such as stationary random fields, which are based on precise probability theory, are not capable of correctly characterizing uncertainty in fiber composites. Next, we motivate the applicability of models based on imprecise uncertainty theory and present a novel fuzzy-stochastic model, which can more accurately describe uncertainties in fiber composites. The new model is constructed by combining stochastic fields and fuzzy variables through a simple calibration-validation approach. Finally, we construct a global-local multiscale algorithm for efficiently computing output quantities of interest. The method aims at approximating required quantities, such as displacements and stresses, in regions of relatively small size, e.g. hot spots or zones. The algorithm uses the concept of representative volume elements and computes a global solution to construct a local approximation that captures the microscale features of the solution. The results are based on and backed by real experimental data.

Fast magnetic field amplification in the early Universe: growth of collisionless plasma instabilities in turbulent media

description: In this work we report a numerical study of the cosmic magnetic field amplification due to collisionless plasma instabilities. The collisionless magnetohydrodynamic equations derived account for the pressure anisotropy that leads, in specific conditions, to the firehose and mirror instabilities. We study the time evolution of seed fields in turbulence under the influence of such instabilities. An approximate analytical time evolution of magnetic field is provided. The numerical simulations and the analytical predictions are compared. We found that i) amplification of magnetic field was efficient in firehose unstable turbulent regimes, but not in the mirror unstable models, ii) the growth rate of the magnetic energy density is much faster than the turbulent dynamo, iii) the efficient amplification occurs at small scales. The analytical prediction for the correlation between the growth timescales with pressure anisotropy ratio is confirmed by the numerical simulations. These results reinforce the idea that pressure anisotropies - driven naturally in a turbulent collisionless medium, e.g. the intergalactic medium -, could efficiently amplify the magnetic field in the early Universe (post-recombination era), previous to the collapse of the first large-scale gravitational structures. This mechanism, though fast for the small scale fields ($\sim$kpc scales), is however unable to provide relatively strong magnetic fields at large scales. Other mechanisms that were not accounted here (e.g., collisional turbulence once instabilities are quenched, velocity shear, or gravitationally induced inflows of gas into galaxies and clusters) could operate afterwards to build up large scale coherent field structures in the long time evolution.

Characterising & classifying the local population of ultracool dwarfs with Gaia DR2 and EDR3
Creators: name: Laithwaite, Richard C.
Publisher: name: Imperial College London
Year: 2022

description: Ultracool dwarfs (UCDs) are the lowest mass products of star formation and span the end of the stellar main sequence from very-low mass, hydrogen-burning M stars to the coolest brown dwarfs. In this thesis we characterise and classify the ultracool dwarf population in the solar neighbourhood using the accuracy and precision of data from the Gaia space observatory. Combining astrometric (in particular parallax) and photometric data from Gaia DR2 and EDR3 with photometry from UKIDSS, SDSS and 2MASS, we prepare some of the largest and most accurate, near-100% complete volume-limited populations of nearby, field late-M, L and T dwarfs. From these samples we derive key population characteristics such as colour-absolute magnitude relationships, the stellar luminosity function, the binary fraction and the binary mass ratio. Our statistical-based approach differs from much of the UCD literature to date which seeks to prepare meta-catalogues from disparate surveys and individual spectroscopic observations with distance determined by indirect methods. Our approach offers improvements in scale, completeness, and distance accuracy. In particular we use Gaia to update the colour-magnitude relations and derive the stellar luminosity functions in MJ and MG of the UCDs. We calculate the binary fraction of the late-M and early-L dwarfs as a function of spectral type by carefully modelling the over-luminous unresolved binary population and show that late-M dwarf binaries reside almost exclusively in equal-mass pairs or twins. Given the complex spectral features of UCDs, consistent and accurate classification is challenging. We investigate the current traditional methods of classification and evaluate a range of alternative techniques including supervised and unsupervised machine learning. In a separate study we use Gaia data to prepare a large, cylindrical sample of FGK main sequence dwarf stars to calculate the structure of the vertical density distribution close to the galactic plane, in fine detail, as a function of colour. Using our derived colour-dependent thin disk scale height we directly determine the star formation history of the solar neighbourhood by modelling the evolution of stellar populations using state-of-the-art PARSEC isochrones.

description: This thesis examines a collection of artifacts taken from a site in Sicily Island, Louisiana
that is thought to have been the location of the historic 1731 battle between French settlers and
the Natchez Indians. The battle is thought of by many to have been the beginning of the end for
the Natchez nation and represents an important moment in the history of the Lower Mississippi
Valley. By combining cartographic, historic, and archaeological evidence, the site at Sicily
Island is shown to be the likeliest candidate for the location of the battle.
The discussion of this battle has often revolved around ambiguities within the maps of the
French campaign against the Natchez. This thesis seeks to explain these ambiguities and uses
these maps to support the idea that the Sicily Island site is the location of the battle. In addition to
this, ten burials found at the site are described in detail, with drawings of how the burials were
arranged and pictures of the artifacts found at each burial. The artifacts associated with these
burials are consistent with what one would expect as the site of the 1731 battle and are very
similar to other 18th century Natchez sites, such as the Fatherland site (Neitzel 1965).

Rhythmic Stimulation and Auditory Masking as Fluency Inducing Techniques in Patients with Post-Stroke Aphasia
Creators: name: Burris, Hannah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Nonfluent aphasia often includes difficulties in fluent speech production, and apraxia of speech (AOS) is a motor programming disorder that commonly co-occurs with aphasia. Rhythmic stimulation, auditory masking, and delayed, frequency-shifted feedback (altered auditory feedback [AAF]) have been shown to effectively increase fluency in people who stutter (another fluency disorder in adults), as well as in some speakers with aphasia. This study investigated the effect of metronomic stimulation on fluency, defined as decreased disfluent time and increased syllable rate, as compared to baseline, auditory masking, and AAF conditions in speakers with aphasia and AOS. Five speakers produced 20 sentences in seven conditions, including masking, AAF, and metronomic stimulation conditions, as well as four control conditions. Results indicated that one of the five speakers responded with a significant decrease in disfluent time with metronomic stimulation (Z= -3.26, p = .003), as determined by the Wilcoxon Rank-Sum test. No speaker significantly improved in fluency during the masking condition, and all speakers declined in fluency during the AAF condition. The one positive responder had a less fluent form of aphasia than most other participants, and also had apraxia of speech. These results suggest that metronomic stimulation may increase fluency in speakers with nonfluent aphasia and apraxia of speech.

description: We prove that every simply connected orthogonal polygon of $n$ vertices can be partitioned into $\left\lfloor\frac{3 n +4}{16}\right\rfloor$ (simply connected) orthogonal polygons of at most 8 vertices. It yields a new and shorter proof of the theorem of A. Aggarwal that $\left\lfloor\frac{3 n +4}{16}\right\rfloor$ mobile guards are sufficient to control the interior of an $n$-vertex orthogonal polygon. Moreover, we strengthen this result by requiring combinatorial guards (visibility is only required at the endpoints of patrols) and prohibiting intersecting patrols. This yields positive answers to two questions of O'Rourke. Our result is also a further example of the "metatheorem" that (orthogonal) art gallery theorems are based on partition theorems.

description: PTCA-Ballonkatheter werden zur Aufweitung von Verengungen der Herzkranzgefäße genutzt. Sie finden in verschiedenen Bauarten Anwendung. Zwischen diesen Kathetertypen und den Kathetern einer Bauart aber verschiedener Hersteller bestehen deutliche Differenzen in der Ausprägung anwendungsrelevanter Kathetermerkmale. In einem neuen Prüfstand für PTCA-Katheter werden der anatomische Aufbau (Lage, Durchmesser, Verzweigungen der Gefäße) und die Reibverhältnisse den physiologischen Verhältnissen nachgebildet. Möglich sind Messungen von Aktionskräften am Antrieb kombiniert mit Reaktionskraftmessungen in Modellgefäßen. Innerhalb dieses Beitrages werden Untersuchungen vorgestellt, die neben Abstützkräften des Katheters im Führungskatheter auch auf die Gefäßwand übertragene Kräfte bei Passage eines gekrümmten Gefäßabschnittes erfassen.

description: The goal of this research was to assess the support for motor speech disorders as explanatory constructs to guide research and treatment of reduced intelligibility in persons with Down syndrome (DS). Participants were the 45 adolescents with DS in the prior paper who were classified into five mutually-exclusive motor speech classifications using the Speech Disorders Classification System. An ordinal index classified participants’ percentage of intelligible words in conversation as High (≥ 85%), Moderate (80% – 84.9%), or Low (< 80%). Statistical analyses tested for significant differences in intelligibility status associated with demographic, intelligence, and language variables, and intelligibility status associated with motor speech classifications and speech, prosody, and voice variables. For the 10 participants who met criteria for concurrent Childhood Dysarthria and Childhood Apraxia of Speech at assessment, 80% had reduced (Moderate or Low) intelligibility and 20% had High intelligibility (significant effect size: 0.644). Proportionally more of the 32 participants who met criteria for either dysarthria or apraxia had reduced intelligibility (significant effect size: 0.318). Low intelligibility was significantly associated with across-the-board reductions in phonemic and phonetic accuracy and with inappropriate prosody and voice. Findings are interpreted as support for motor speech disorders in adolescents with DS as explanatory constructs for their reduced intelligibility. Pending cross-validation of findings in diverse samples of persons with DS, studies are needed to assess the efficacy of motor speech classification status to guide selection of treatment methods and intelligibility targets.

description: Although there is substantial rationale for a motor component in the speech of persons with Down syndrome (DS), there presently are no published estimates of the prevalence of subtypes of motor speech disorders in DS. The goal of this research is to provide initial estimates of the prevalence of types of speech disorders and motor speech disorders in adolescents with DS. Conversational speech samples from a convenience sample of 45 adolescents with DS, ages 10 to 20 years old, were analysed using perceptual and acoustic methods and measures in the Speech Disorders Classification System (SDCS). The SDCS cross-classified participants into five mutually exclusive speech classifications and five mutually exclusive motor speech classifications. For participants meeting criteria for Childhood Dysarthria or for Childhood Dysarthria concurrent with Childhood Apraxia of Speech, the SDCS provided information on participants’ percentile status on five subtypes of dysarthria. A total of 97.8% of participants met SDCS criteria for Speech Disorders and 97.8% met criteria for Motor Speech Disorders, including Childhood Dysarthria (37.8%), Speech Motor Delay (26.7%), Childhood Dysarthria and Childhood Apraxia of Speech (22.2%), and Childhood Apraxia of Speech (11.1%). Ataxia was the most prevalent dysarthria subtype. Nearly all participants with DS in the present sample had some type of speech and motor speech disorder, with implications for theory, assessment, prediction, and treatment. Specific to treatment, the present findings are interpreted as support for motor speech disorders as a primary explanatory construct to guide the selection and sequencing of treatment targets for persons with DS.

description: We study a lattice point counting problem for a class of families of domains in a Euclidean space. This class consists of anisotropically expanding bounded domains, which remain unchanged along some fixed linear subspace and expand in directions, orthogonal to this subspace. We find the leading term in the asymptotics of the number of lattice points in such family of domains and prove remainder estimates in this asymptotics under various conditions on the lattice and the family of domains. As a consequence, we prove an asymptotic formula for the eigenvalue distribution function of the Laplace operator on a flat torus in adiabatic limit determined by a linear foliation with a nontrivial remainder estimate.

description: Eine weitverbreitete Methode zur Behandlung nicht operabler Tumore ist die Hyperthermie. Eine Möglichkeit während dieser Behandlung die Temperatur zu kontrollieren, bietet die Kernspintomographie. Ihre Vorteile sind die gute Ortsauflösung, der gute Weichteilkontrast, die beliebige Wahl des Schnittbildverlaufs und ihr geringes Risiko für Nebenwirkungen. Innerhalb dieses Beitrags wird die Entwicklung einer quantitativen ort- und zeitaufgelösten Temperaturmessung im MR an einem gewebenahen Phantom vorgestellt.

description: The aim of this work was to 1) identify the impact occupational exposure to wildfires has on health outcomes of personnel including physical, mental, and social well-being, 2) examine the characteristics and effectiveness of mitigation strategies or policies to reduce negative health impacts, and 3) develop a program of research to address and understand the health impacts of occupational exposure to wildfires based on gaps in the literature and stakeholder priorities. This scoping review of the literature was combined with a modified Delphi process to explore the relevance and appropriateness of mitigation strategies for the British Columbia, Canada wildfire context, and define priorities for health research within British Columbia.
