Abstract:

Resonant ultrasound spectroscopy (RUS) is a technique that uses a combination of experimentally measured resonant frequencies and physics-based computation of these frequencies to determine the entire set of single crystal elastic constants of a material. Computation of the resonances is most often accomplished using the Rayleigh–Ritz energy minimization method but this requires knowledge of mass density and analytical representation of the shape of the material. As a result, the sample will be manufactured into a canonical geometry such as cylinder or a rectangular parallelepiped such that its displacement field can be represented by a set of basis function. In this approach, deviation from a perfect canonical geometry can have a significant impact on the estimate elastic constants during the inversion. To overcome this limitation, this project describes a finite element method combined with x-ray computed tomography to model a sample with complex shape for computation of resonance frequencies and in the inversion of the elastic constants.

Abstract:

The theoretical description and experimental verification of resonant phenomena in electromagnetic fields generated in the near zone of all-dielectric rectangular thin sub wavelength frames, subjected to an incident microwave, is considered. The geometry of considered problems is presented by means of arrangements of these frames in three orthogonal planes, normal respectively to electric component, magnetic component and wave vector of the incident wave. Such trio paves the way to design of 3D all-dielectric multiresonant microwave unit cell. Displacement currents, generated by linearly polarized electromagnetic waves in the system, lead to the formation of magnetic and electric dipoles, each of which possess own resonant frequency. Resonant inversion of magnetic inductance and electric displacement is observed. The sliding incidence of plane wave on the frame is shown to provide the sharp and deep resonance in the components of generated field. The phase shift equal to π between the magnetic components of incident and generated wave indicates the formation of negative magnetic response. There observes the angular anisotropy of arising dipoles, manifested in values of resonance frequencies and in the dependence of depths of resonant spectral dips upon the orientation of dipoles, with respect to the direction of propagation of incident wave.

Abstract:

Within the Luttinger Hamiltonian, electric-field-induced resonant spin polarization of a two-dimensional hole gas in a perpendicular magnetic field was studied. The spin polarization arising from splitting between the light and the heavy hole bands shows a resonant peak at a certain magnetic field. Especially, the competition between the Luttinger term and the structural inversion asymmetry leads to a rich resonant peaks structure, and the required magnetic field for the resonance may be effectively reduced by enlarging the effective width of the quantum well. Furthermore, the Zeeman splitting tends to move the resonant spin polarization to a relative high magnetic field and destroy these rich resonant spin phenomena. Finally, both the height and the weight of the resonant peak increase as the temperature decreases. It is believed that such resonant spin phenomena may be verified in the sample of a two-dimensional hole gas, and it may provide an efficient way to control spin polarization by an external electric field.

Abstract:

Numerical modeling results and field data indicate that some contrasting subsurface objects (such as tunnels, caves, pipes, filled pits, and fluid-filled fractures) are capable of generating durable resonant oscillations after trapping seismic energy. These oscillations consist of surface types of circumferential waves that repeatedly propagate around the object. The resonant emission of such trapped energy occurs primarily in the form of shear body waves that can be detected by remotely placed receivers. Resonant emission reveals itself in the form of sharp resonant peaks for the late parts of the records, when all strong direct and primary reflected waves are gone. These peaks were observed in field data for a buried barrel filled with water, in 2D finite-difference modeling results, and in the exact canonical solution for a fluid-filled sphere. A computed animation for the diffraction of a plane wave upon a low-velocity elastic sphere confirms the generation of resonances by durable surface waves. Resonant emission has characteristic quasi-hyperbolic traveltime patterns on shot gathers. The inversion of these patterns can be performed in the frequency domain after muting the strong direct and primary scattered waves. Subsurface objects can be detected and imaged at a single resonance frequency without an accurate knowledge of source trigger time. The imaging of subsurface objects requires information about the shear velocity distribution in an embedding medium, which can be done interactively during inversion.

Les séismes de grande magnitude (MW > 7) et les tsunamis associés induisent des perturbations qui peuvent être détectées dans l’atmosphère et l’ionosphère à partir des mesures TEC (contenu total en électron).

Thus, I study the coupling between the solid Earth, the ocean, the atmosphere. I demonstrate that only the resonance at 1.5 mHz between the tsunami modes and the atmospheric gravity modes can be detected through ionosphere and highlight the fact that the efficiency of the coupling ocean/atmosphere is sensitive to ocean depth and local time. These developments enables the complete modelling of the ionospheric signature of 3 tsunami with an amplitude of 2, 3 and 60cm in deep ocean: the 2012 Haida Gwaii and the 2006 Kuril tsunami in far field and the 2011 Tohoku tsunami in closer field respectively. Finally, we demonstrated that the peak-to- peak amplitude of the height of the inverted tsunami reconstructs with less than 20% error the amplitude measured by a DART buoy in these three cases

Abstract:

Magnetic resonance-based electric properties tomography (MREPT) is a recent quantitative imaging technique that could provide useful additional information to the results of magnetic resonance imaging (MRI) examinations. Precisely, MREPT is a collective name that gathers all the techniques that elaborate the radiofrequency (RF) magnetic field B1 generated and measured by a MRI scanner in order to map the electric properties inside a human body. The range of uses of MREPT in clinical oncology, patient-specific treatment planning and MRI safety motivates the increasing scientific interest in its development. The main advantage of MREPT with respect to other techniques for electric properties imaging is the knowledge of the input field inside the examined body, which guarantees the possibility of achieving high-resolution. On the other hand, MREPT techniques rely on just the incomplete information that MRI scanners can measure of the RF magnetic field, typically limited to the transmit sensitivity B1+. In this thesis, the state of art is described in detail by analysing the whole bibliography of MREPT, started few years ago but already rich of contents. With reference to the advantages and drawbacks of each technique proposed for MREPT, the particular implementation based on the contrast source inversion method is selected as the most promising approach for MRI safety applications and is denoted by the symbol csiEPT. Motivated by this observation, a substantial part of the thesis is devoted to a thoroughly study of csiEPT. Precisely, a generalised framework based on a functional point of view is proposed for its implementation. In this way, it is possible to adapt csiEPT to various physical situations. In particular, an original formulation, specifically developed to take into account the effects of the conductive shield always employed in RF coils, shows how an accurate modelling of the measurement system leads to more precise estimations of the electric properties. In addition, a preliminary study for the uncertainty assessment of csiEPT, an imperative requirement in order to make the method reliable for in vivo applications, is performed. The uncertainty propagation through csiEPT is studied using the Monte Carlo method as prescribed by the Supplement 1 to GUM (Guide to the expression of Uncertainty in Measurement). The robustness of the method when measurements are performed by multi-channel TEM coils for parallel transmission confirms the eligibility of csiEPT for MRI safety applications.

Abstract:

Magnetic Resonance Elastography (MRE) is an emerging medical imaging modality that allows quantification of the mechanical properties of biological tissues in vivo. MRE typically involves time-harmonic tissue excitation followed by the displacement measurements within the tissue obtained by phase-contrast Magnetic Resonance Imaging (MRI) techniques. MRE is believed to have great potential in the detection of wide variety of pathologies, diseases and cancer formations, especially tumors. This thesis concentrates on a thorough assessment and full rheological evaluation of the Rayleigh damping (RD) material model applied to MRE. The feasibility of the RD model to accurately reconstruct viscoelastic and damping properties was assessed. The goal is to obtain accurate quantitative estimates of the mechanical properties for the in vivo healthy brain via the subzone optimization based nonlinear image reconstruction algorithm. The RD model allows reconstruction of not only stiffness distribution of the tissue, but also energy attenuation mechanisms proportionally related to both elastic and inertial effects. The latter allows calculation of the concomitant damping properties of the material. The initial hypothesis behind this research is that accurate reconstruction of the Rayleigh damping parameters may bring additional diagnostic potential with regards to differentiation of various tissue types and more accurate characterisation of certain pathological diseases based on different energy absorbing mechanisms. Therefore, the RD model offers reconstruction of three additional material properties that might be of clinical diagnostic merit and can enhance characterisation of cancer tumors within the brain. A pneumatic-based actuator was specifically developed for in vivo human brain MRE experiments. Performance of the actuator was investigated and the results showed that the actuator produces average displacement in the range of 300 µmicrons and is well suited for generation of shear waves if applied to the human head. Unique features of the the actuator are patient comfort and safety, MRI compatibility, flexible design and good displacement characteristics. In this research, a 3D finite element (FE) subzone-based non-linear reconstruction algorithm using the RD material model has been applied and rigorously assessed to investigate the performance of elastographic based reconstruction to accurately recover mechanical properties and a concomitant damping behaviour of the material. A number of experiments were performed on a variety of homogenous and heterogeneous tissue-simulating damping phantoms comprising a set of materials that mimic range of mechanical properties expected in the brain. The result showed consistent effect of a poor reconstruction accuracy of the RD parameters which suggested the nonidentifiable nature of the RD model. A structural model identifiability analysis further supported the nonidentifiabilty of the RD parameters at a single frequency. Therefore, two approaches were developed to overcome the fundamental identifiability issue. The first one involved application of multiple frequencies over a broad range. The second one was based on parametrisation techniques, where one of the damping parameters was globally defined throughout the reconstruction domain allowing reconstruction of the two remaining parameters. Based on the findings of this research, multi-frequency (MF) elastography was performed on the tissue-simulating phantoms to investigate improvement of the elastographic reconstruction accuracy. Dispersion characteristics of the materials as well as RD changes across different frequencies in various materials were also studied. Simultaneous multi-frequency inversion was undertaken where two models were evaluated: a zero-order model and a power-law model. Furthermore, parametric-based RD reconstruction was carried out to evaluate enhancement of accurate identification of the reconstructed parameters. The results showed that parametric-based RD reconstruction, compared to MF-based RD results, allowed better material characterisation on the reconstructed shear modulus image. Also, significant improvement in material differentiation on the remaining damping parameter image was also observed if the fixed damping parameter was adjusted appropriately. In application to in vivo brain imaging, six repetitive MRE examinations of the in vivo healthy brain demonstrated promising ability of the RD MRE to resolve local variations in mechanical properties of different brain tissue types. Preliminary results to date show that reconstructed real shear modulus and overall damping levels correlate well with the brain anatomical features. Quantified shear stiffness estimates for white and gray matter were found to be 3 kPa and 2.1 kPa, respectively. Due to the non-identifiability of the model at a single frequency, reconstructed RD based parameters limit any physical meaning. Therefore, MF-based and parametric-based cerebral RD elastography was also performed.

Abstract:

BACKGROUND: The abnormal signal intensity in cardiac T₂-weighted images is associated with various pathologies including myocardial edema. However, the assessment of pathologies based on signal intensity is affected by the acquisition parameters and the sensitivities of the receiver coils. T₂ mapping has been proposed to overcome limitations of T₂-weighted imaging, but most methods are limited in spatial and/or temporal resolution. Here we present and evaluate a double inversion recovery radial fast spin-echo (DIR-RADFSE) technique that yields data with high spatiotemporal resolution for cardiac T₂ mapping. METHODS: DIR-RADFSE data were collected at 1.5 T on phantoms and subjects with echo train length (ETL) = 16, receiver bandwidth (BW) = +/-32 kHz, TR = 1RR, matrix size = 256 x 256. Since only 16 views per echo time (TE) are collected, two algorithms designed to reconstruct highly undersampled radial data were used to generate images for 16 time points: the Echo-Sharing (ES) and the CUrve Reconstruction via pca-based Linearization with Indirect Echo compensation (CURLIE) algorithm. T₂ maps were generated via least-squares fitting or the Slice-resolved Extended Phase Graph (SEPG) model fitting. The CURLIE-SEPG algorithm accounts for the effect of indirect echoes. The algorithms were compared based on reproducibility, using Bland-Altman analysis on data from 7 healthy volunteers, and T₂ accuracy (against a single-echo spin-echo technique) using phantoms. RESULTS: Both reconstruction algorithms generated in vivo images with high spatiotemporal resolution and showed good reproducibility. Mean T₂ difference between repeated measures and the coefficient of repeatability were 0.58 ms and 2.97 for ES and 0.09 ms and 4.85 for CURLIE-SEPG. In vivo T₂ estimates from ES were higher than those from CURLIE-SEPG. In phantoms, CURLIE-SEPG yielded more accurate T₂s compared to reference values (error was 7.5-13.9% for ES and 0.6-2.1% for CURLIE-SEPG), consistent with the fact that CURLIE-SEPG compensates for the effects of indirect echoes. The potential of T₂ mapping with CURLIE-SEPG is demonstrated in two subjects with known heart disease. Elevated T₂ values were observed in areas of suspected pathology. CONCLUSIONS: DIR-RADFSE yielded TE images with high spatiotemporal resolution. Two algorithms for generating T₂ maps from highly undersampled data were evaluated in terms of accuracy and reproducibility. Results showed that CURLIE-SEPG yields T₂ estimates that are reproducible and more accurate than ES.

For this, various techniques for controlling power has been studied in order to meet the robustness characteristics, accuracy and speed of response. In addition, another important characteristic, which has been adopted for accurately determining the choice of the current driver is the possibility of eliminating disturbances in specific frequency, such as those caused by harmonicas of the fundamental signal. This paper presents the study, analysis and resonant controller design. Since this controller is equivalent to adding two PI controllers synchronously, a positive sequence and negative sequence other, implemented in the stationary frame of reference, we will investigate the possible resonance structures of controlling synchronous equivalent to PI controllers, and vector classic and the advantages and disadvantages of each. The analyses of resonant controllers are held in the continuous domain and then the drivers are implemented in discrete domain, taking into account the computational delay. It is also performed the analysis and design of strategies for controlling resonant with and without a delay compensator. Finally, experimental tests will be performed to confirm the analyzes in this paper.<br>Com o avanço da eletrônica de potência e a vasta gama de aplicações que envolvem os inversores monofásicos de tensão, os controladores de corrente têm ganhado grande destaque, pois controlam o fluxo de energia fornecida à rede elétrica ou a uma carga e compensam alguns problemas de qualidade de energia. Para isso, diversas técnicas de controladores de corrente têm sido estudadas com o intuito de atender as características de robustez, precisão e rapidez na resposta. Além disso, outra característica importante, e que tem sido rigorosamente adotada para determinar a escolha dos controladores de corrente, é a possibilidade de eliminar distúrbios em frequências específicas, como por exemplo, aqueles causados por harmônicas do sinal fundamental. Esta dissertação apresenta o estudo, análise e projeto do controlador ressonante. Uma vez que este controlador é equivalente à adição de dois controladores PI síncronos, um de sequência positiva e outro de sequência negativa, implementados no referencial estacionário, serão investigados as possíveis estruturas dos controladores ressonantes equivalentes aos controladores PI síncronos, clássico e vetorial, bem como as vantagens e desvantagens de cada um. As análises dos controladores ressonantes são realizadas no dominio contínuo e, posteriormente, os controladores são implementados no dominio discreto, levando em consideração o atraso computacional. Também é realizada a análise e projeto das estratégias de controladores ressonantes com e sem um compensador de atraso. Por fim, serão realizados ensaios experimentais para confirmar as análises realizadas no decorrer deste trabalho.

Abstract:

Baseado em uma seqüência já conhecida de Multislice Spin Echo convencional, implementamos uma seqüência do tipo Modified Driven Equilibrium Fourier Transform (MDEFT) adiabática multislice em um sistema de 2T e um de microimagens (9.4T). Essa metodologia utiliza, como pulso de inversão, um pulso de RF com modulação em amplitude e freqüência, conhecido por pulso adiabático. Dessa forma, os tempos de inversão são iguais para todos os planos selecionados, resultando num contraste por T1 uniformemente distribuído ao longo dos mesmos. O uso de um único e longo pulso adiabático de inversão tem, ainda, a vantagem de utilizar uma potência de pico menor para operar da mesma forma que um grupo de m pulsos convencionais. Utilizamos pulsos cujas modulações correspondentes de fase e freqüência foram calculadas com base nas condições de Offset Independent Adiabaticity (OIA) e a real eficiência dos mesmos foi avaliada através de simulações e experimentalmente. Para realização dos testes da metodologia desenvolvemos e caracterizamos dois phantoms, cujas imagens demonstram a aplicabilidade da metodologia nos dois sistemas utilizados.<br>Based on the conventional Multislice Spin Echo pulse sequence, we implemented an adiabatic multislice Modified Driven Equilibrium Fourier Transform (MDEFT) pulse sequence on a 2T and a 9.4T microimaging system. This methodology uses, as inversion pulse, an amplitude and frequency modulated RF pulse, known as adiabatic pulse. In that way, the inversion times are the same for all slices, resulting in an evenly distributed T1 contrast. A single and long adiabatic inversion pulse has in addition the advantage of using a reduced peak power to perform in the same way as the group of m conventional pulses. We used pulses whose corresponding phase and frequency modulations were based on Offset Independent Adiabaticity and their real efficiency were evaluated both through simulations and experimentally. To test the methodology, we developed and characterized two phantoms, whose images demonstrate the applicability of the methodology in the two mentioned systems.

Abstract:

Chapter 3 addresses the Old Testament figure of Job. It considers the resonance of his biblical narrative amid a climate of religious persecution in Europe. Job’s narrative was typically understood to mark bodily suffering as a test of faith and, for many readers, affirmed that their suffering, like Job’s, was divinely authorized for a finite period of time. A wave of theological and literary writings affirm the remarkable impact of the Joban trajectory of suffering in early modern culture. Shakespeare’s King Lear is no exception. Yet, instead of upholding the Joban paradigm of eventual restoration—a feature of the anonymous source play, King Leir—Shakespeare’s play is notable for its deliberate disruption of the typological process of promise and fulfilment. In fact, this play offers a shocking inversion of established exegetical traditions of suffering more generally.

Abstract:

In designing the terahertz quantum cascade lasers, electron injection manner indeed plays a significant role to achieve the population inversion. The resonant tunneling process is commonly employed for this injection process but waste more than 50% fraction of populations out of the active region owing to resonance alignment, and the injection efficiency is obviously degraded due to thermal incoherence. An alternative approach is to consider the phonon-assisted injection process that basically contributes to most of the populations to the upper lasing level. However, this manner is still not realized in experiments if a short-period design only containing two quantum wells is used. In this work, it is found in this design that the population inversion is indeed well improved; however, the optical gain is inherently low even at a low temperature. Those two opposite trends are ascribed to a strong parasitic absorption overlapping the gain. The magnitude of this overlap is closely related to the lasing frequency, where frequencies below 3 THz suffer from fewer effects.

Abstract:

Graves’ disease is the most common autoimmune disorder of the thyroid gland, and ophthalmopathy is one of the most common complications of the disease. The major morbidities of ophthalmopathy are sight-threatening dysthyroid optic neuropathy (DON), proptosis, strabismus, and diplopia. The main imaging modalities for the evaluation of Grave’s ophthalmopathy are the orbit computed tomography scan (CT scan) and orbit magnetic resonance imaging (MRI), which, along with clinical and laboratory findings, help predict, monitor, and follow up after proper medical or surgical management. The benefits of the orbit CT scan are cost-effectiveness, ready-to-access, fast imaging, and simultaneous imaging evaluation of both soft tissue and bony orbits. The orbital apex crowding is the main indication of orbit CT scan and, consequently, decompression surgery in moderate-to-severe inactive ophthalmopathy in our tertiary referral hospital. The MRI can demonstrate the extraocular muscle edema on T2-weighted, short tau inversion recovery (STIR), and/or turbo inversion recovery magnitude (TIRM) images in active cases, which is useful for medical treatment. The objective of this chapter is to introduce the technique, indications, and clinically useful orbit CT scan findings in Graves’ ophthalmopathy before and after decompression surgery, which will be discussed in detail based on our experience and relevant medical literature.

Abstract:

Women municipal councillors in Dehradun, India, represent themselves as social workers, in affectionate relationships with their constituents. Yet often they are positioned as servants, required to undertake petty work on behalf of an ungrateful citizenry. This chapter argues that collective forms of affect make possible, if not probable this positioning. Affective practices of supplication during election campaigns resonate in the relationships between constituents and elected representatives, making durable what is most often considered only a temporary inversion of social hierarchies on election day. A moral atmosphere of clientelism makes political actors susceptible to engendering suspicion and disdain in others, further emboldening an assertive citizenry to make demands that far exceed their entitlements. These collective conditions shape the possibilities for self of women municipal councillors; becoming a ‘servant’ reveals the limits of their self-authorship.

Abstract:

The laser dynamics arising from quasi-resonant interaction between a single mode field and a medium with a homogeneously broadened gain line is described by the equations coupling five variables, namely, the complex field amplitude E, the complex medium polarization P and the real population inversion D. At resonance, E and P are real and the equations reduce to where k, γ1 and γ11 are the relaxation rates of field, polarization and population, respectively, and D0 is the population imposed by the pump.
