Abstract:
In a previous study, the vertical glottal duct length was examined for its influence on intraglottal pressures and other aerodynamic parameters in the uniform glottis [J Voice 32, 8–22 (2018)]. This study extends that work for convergent glottal angles, the shape of the glottis during the glottal opening phase of vocal fold vibration. The computational fluid dynamics code ANSYS Fluent 6.3 was used to obtain the pressure distributions and other aerodynamic parameters for laminar, incompressible, two-dimensional flow in a static vocal fold model. Four typical vertical glottal duct lengths (0.108, 0.308, 0.608, 0.908 cm) were selected for three minimal diameters (0.01, 0.04, 0.16 cm), three transglottal pressures (500, 1000, 1500 Pa), and three convergent glottal angles (−5°, −10°, −20°). The results suggest that a longer vertical glottal duct length increases the intraglottal pressures, decreases the glottal entrance loss coefficient, increases the transglottal pressure coefficient, causes a lower gradient of both the intraglottal flow velocity and the wall shear stress along the glottal wall—especially for low flows and small glottal minimal diameters—and has little effect on the exit pressure coefficient and volume flow. The vertical glottal duct length in the convergent glottis has important effects on phonation and should be well specified when building computational and physical models of the vocal folds.

Abstract:
Voice pathology is the result of improper vocal use. Poor vocal exercise and repeated laryngeal infection may lead to worse voice quality and vocal stresses. This work uses glottal signal parameters obtained from speakers of distinct ages to identify voice disorders. The parameters obtained from the glottal signal, Mel Frequency Cepstrum Coefficients (MFCCs) and combination of glottal and MFFCs are used for pathological voice classification. Support Vector Machine (SVM) and K-Nearest Neighbours (KNN) algorithms are used. Results show that best classification results are achieved using combinations of MFFCs and with glottal parameters including MOQ, which is a novel outcome and most important involvement of this study, with an average efficiency improvement of 3%.

Abstract:
Glottal area waveform (GAW) is the plot of relative glottal area versus time through 1 representative glottal cycle. It is derived from the quantitative analysis of the videostroboscopic image. A GAW analysis was performed on 24 patients before and after microlaryngeal phonosurgery. Patients with vocal fold polyps, polypoid degeneration, cysts, sulcus vocalis, and Reinke's edema were included. From each GAW, 5 parameters were determined and compared: maximum normalized glottal area, maximum opening rate, maximum closing rate, percent open time at 50% glottal opening, and glottal gap size. Statistically significant differences in postoperative states included an increased maximum glottal area, an increased maximum opening rate, and an increased maximum closing rate. Glottal opening and closing rate are objective measures of vocal fold pliability that have clinical relevance. The GAW may be used to quantitate vocal fold vibratory capability.

Abstract:
Purpose The aim of the present study was to qualitatively and quantitatively characterize vocal fold vibrations in sulcus vocalis by high-speed digital imaging (HSDI) and to clarify the correlations between HSDI-derived parameters and traditional vocal parameters. Method HSDI was performed in 20 vocally healthy subjects (8 men and 12 women) and 41 patients with sulcus vocalis (33 men and 8 women). Then HSDI data were evaluated by assessing the visual–perceptual rating, digital kymography, and glottal area waveform. Results Patients with sulcus vocalis frequently had spindle-shaped glottal gaps and a decreased mucosal wave. Compared with the control group, the sulcus vocalis group showed higher open quotient as well as a shorter duration of the visible mucosal wave, a smaller speed index, and a smaller glottal area difference index ([maximal glottal area – minimal glottal area]/maximal glottal area). These parameters deteriorated in order of the control group and Type I, II, and III sulcus vocalis. There were no gender-related differences. Strong correlations were noted between the open quotient and the type of sulcus vocalis. Conclusions HSDI was an effective method for documenting the characteristics of vocal fold vibrations in patients with sulcus vocalis and estimating the severity of dysphonia.

Abstract:
The detection and description of pathological voice are the most important applications of voice profiling. Currently, techniques like laryngostroboscopy or surgical microlarynoscopy are popularly used for the diagnosis of voice pathologies but are invasive in nature. Disorders of vocal folds impact the quality of voice, and therefore, the accuracy of voice profiling is reduced. This paper presents a better solution to differentiate normal and pathological voices based on the glottal, physical, and acoustic and equivalent electrical parameters. These parameters have been correlated using mathematical equations and models. Results reveal that the glottal flow is strongly influenced by physical parameters like stiffness and viscosity of vocal folds in case of pathological voice. However, their direct measurement requires complex invasive medical procedures or costly and complex electronic hardware arrangements in case of non-invasive methods. Glottal parameters, on the other hand, facilitate much simpler estimation of vocal folds disorders. In this work, the authors have presented two non-invasive approaches for better accuracy and least complexity for differentiating normal and pathological voices: 1) by using correlation of glottal and physical parameters, 2)by using acoustic and equivalent electrical parameters.

Abstract:
The discrimination of voice signals has numerous applications in diagnosing of pathologies related to voice. This paper discussed about the glottal signal that is bound to recognize two sorts of voice issue: Laryngitis and Laryngeal dystonia (LD). The parameters of the glottal signal fill in as contribution to classifiers that characterizes into three unique gatherings of speakers: speakers with Laryngitis; with laryngeal dystonia (LD); lastly speakers with healthy voices. The database is made out of voice accounts containing tests of three gatherings. The classifiers SVM provided 60%, KNN provided 70% and Ensemble provided 80% classification accuracy in the case of Laryngitis. Voice signals of patients affected with Laryngeal dystonia were also collected and tested with same classifiers and the Accuracy of 90%, 80% and 50% were obtained with SVM, KNN and Ensemble respectively.

Abstract:
Cette étude s'intéresse au problème de l'inversion d'un modèle de production de la voix étant donné un enregistrement audio de parole pour obtenir une représentation de le source sonore qui est générée au niveau de la glotte, la source glottique, ainsi qu'un représentation des résonances et anti-résonances créées par les cavités du conduit vocal. Cette séparation des éléments composants la voix donne la possibilité de manipuler indépendamment les caractéristiques de la source et le timbre des résonances. Nous supposons que la source glottique est un signal à phase mixte et que la réponse impulsionnelle du filtre du conduit vocal est un signal à minimum de phase. Puis, considérant ces propriétés, différentes méthodes sont proposées pour estimer les paramètres d'un modèle glottique qui minimisent la phase carrée moyenne du résiduel convolutif d'un spectre de parole observé et de son modèle. Une dernière méthode est décrite où un unique paramètre de forme est solution d'une forme quasi fermée du spectre observé. Ces méthodes sont évaluées et comparées avec des méthodes de l'état de l'art en utilisant des signaux synthétiques et electro-glotto-graphiques. Nous proposons également une procédure d'analyse/synthèse qui estime le filtre du conduit vocal en utilisant un spectre observé et sa source estimée. Des tests de préférences ont été menés et leurs résultats sont présentés dans cette étude pour comparer la procédure décrite et d'autres méthodes existantes.

Abstract:
Photoacoustic imaging for biomedical application has attracted much research in recent years. To date, most of the work has focused on pulsed photoacoustics. Recent developments have seen the implementation of a radar pulse compression methodology into continuous wave photoacoustic modality, however very little theory has been developed in support of this approach. In this thesis, the one-dimensional theory of radar photoacousticsfor pulse compressedlinear frequency modulated continuous sinusoidal laserphotoacoustics is developed.The effect of the chirp parameters on the corresponding photoacoustic signal is investigated, and guidelines for choosing the chirp parametersfor absorber profilometric detectionare given based on the developed theory and simulations. Simulated results are also compared to available experimental results and show a good agreement.

Abstract:
With the rise in prevalence of cardiovascular (CV) disease, risk stratification is becoming increasingly important. Accurate characterization of the CV system is required, for which central aortic blood pressure (BP) parameters form an integral part. However, invasive measurement of central aortic BP parameters (aP) is difficult. Therefore, non-invasive methods to estimate aP from the radial pressure pulse (rPulse) have been proposed. To analyze accuracy of estimated aP (aPhat) and applicability in risk stratification and diagnosis, this study presents: (1) a novel representation of the rPulse with minimal loss of information, (2) a framework for strict definition and statistical analysis of aPhat, and (3) a dynamic analysis of effects of mean BP (MP) and heart rate (HR) in the rPulse shape. Methods: (1) 2671 rPulse s measured by applanation tonometry were represented using the first eight principal components (PC) scores after standard PC transformation. rPulse shapes were compared in three subpopulations. (2) The concept of "estimation option" (EO) for aP estimation was presented. A framework for strict definition of aPhat and the comparison of EOs was proposed, and 7 different EOs compared. (3) A sequence of rPulse s was analyzed during soft exhalation maneuver (SEM) %, a mild Valsalva type maneuver, in eight healthy subjects. Radial BP and respiration pressure were continuously measured. The effects of MP and HR in the rPulse parameters were analyzed by standard linear regression for each subject. Results: (1) PC representation of the rPulse improves accuracy of the estimation of aPhat compared with the simple use of rPulse parameters. Subpopulations have distinctive rPulse shapes. (2) No single EO was better for the estimation of all aPhat. Inclusion of MP improves estimation accuracy. Despite further improvement when rPulse is included, the general transfer function EO is a biased estimator. (3) The dynamic analysis of the rPulse provides information of the effects of MP and HR in the rPulse not available in static analysis. The effects were specific for each individual and different from the results obtained from a general population. Conclusions: For accurate CV risk stratification, future studies should include a dynamic measurement of calibrated radial pressure pulse during SEM maneuver. Risk analysis and diagnosis should be based on representations of the rPulse with minimum loss of information. aPhat should be used for better understanding of the underlying physiological principles.

Abstract:
High Duty Cycle echolocating bats use high frequency echolocation pulses that have limited range but are clutter resistant i.e. can detect targets in dense clutter (the number of echoes produced other than those from the target of interest). A specialised echolocation pulse design (consisting of a constant frequency and frequency modulated components) facilitates foraging for prey in habitats characterised by dense vegetation or clutter. The constant frequency component, along with an acoustic fovea and Doppler Shift Compensation, allows them to distinguish small moving targets from stationary background objects. The frequency modulated components are thought to be used for depth resolution (i.e. ranging acuity). In contrast to their clutter specialist status, these species are found in a variety of biomes including open desert. A negative correlation between level of environmental clutter and frequency has been established for some species. The Foraging Habitat Hypothesis (FHH) proposes that the evolution of echolocation frequency is linked with changes in habitat clutter. In High Duty Cycle bats, the FHH predicts areas of low clutter should select lower frequency pulses because they are less susceptible to atmospheric attenuation making them more suited to long distance prey detection. Previous research has therefore focused on the methods by which bats vary the frequency of their pulses to achieve optimal propagation distances. However, the source levels of these signal emissions are also under control of the bat and must play a major role in signal propagation and therefore in detection of prey. My study tested the FHH by combining both an observational and experimental approach to determine how habitat clutter influences echolocation pulse divergence in High Duty Cycle bats. My focal species was Rhinolophus capensis, which has previously been shown to use different pulse frequencies apparently associated with differences in habitat structure. I focused on two populations, R. capensis in the fynbos (pulse frequency: 84 kHz) and R. capensis in the desert (pulse frequency: 74 kHz). Bats were recorded using a multiple microphone array in their natural habitat and in a flight room experiment where they were exposed to both a cluttered (simulating the fynbos biome) and open (simulating the desert biome) flight room. The experiment determined whether observed differences were a result of possible selection (as proposed by the FHH) or behavioural flexibility. A congeneric species, iii R. damarensis, was used as a control and additional test of the FHH because it inhabits the same desert biome as R. capensis but echolocates at a higher frequency (equivalent to the frequency used by R. capensis in the fynbos). In accordance with this hypothesis, I also tested if there were differences in the frequency modulated components of R. capensis pulses between biomes and whether these differences were due to possible selection for optimal ranging acuity in response to the degree of clutter in each biome. My results suggest the use of lower frequency echolocation pulses in R. capensis in the desert could have evolved for increased detection distance (as proposed by the FHH) but that lower frequencies may not be a prerequisite for successful foraging in open biomes. In R. capensis the greatest differences in prey detection between biomes was a product of both frequency and source level. However, higher source levels used by R. capensis in the desert had a greater contribution to observed differences in detection distances both within (emergence versus foraging area, cluttered versus open flight room) and between biomes (desert versus fynbos) than frequency. In addition, on average R. damarensis did not compensate for higher frequencies with higher source levels resulting in lower average detection distances than R. capensis in the desert. However, a few measurements of source levels for R. damarensis were the highest recorded and resulted in the largest prey detection distances recorded in my study. These findings support recent findings that suggest that SLs are energetically costly. In both biomes, bats used lower source levels when exposed to a cluttered versus open flight room. In the desert biome, bats actively lowered their source levels (compared to the source levels they use in the field) when exposed to a level of clutter that they do not experience naturally (cluttered flight room treatment). Unlike source levels, frequency (of the constant frequency component) was conserved during the flight room treatments. Frequency differences between R. capensis in the different biomes can therefore be attributed to possible selection rather than behavioural flexibility. The conservation of frequency prompted bats to vary their source levels to achieve appropriate detection distances when exposed to different environmental stimuli. Source level flexibility may therefore be the key to the capability of specialist clutter foragers to successfully hunt and survive in harsh open environments. To the same extent that source levels facilitate foraging in open environments, the frequency modulated components of High Duty Cycle bat pulses may facilitate the orientation and foraging of these bats in cluttered biomes. In accordance with the FHH, a strong correlation was found between the frequency (i.e. number of occurrences)/bandwidth of these components and the level of environmental clutter both within iv (between the two treatments of the experiment) and between biomes. The findings in my study highlight the importance of environmental pressures, such as clutter, in shaping the echolocation pulse parameters of bats.

Abstract:
Muitas pesquisas tem sido feitas em processamento digital de sinais (PDS) na tentativa de se avaliar o sinal de fala para diagnosticar doenças da laringe. Medidas acústicas têm sido propostas de forma a avaliar indiretamente o trato glotal por meio do sinal de voz coletado através de microfone convencional. Para isso, o modelo paramétrico Liljencrants-Fant (LF) foi desenvolvido para representar o sinal glotal em condições normais e patológicas. Tais parâmetros apresentam vantagens sobre medidas acústicas por possuírem características fisiológicas reais das pregas vocais. Assim, podendo ser empregados para identificação de doenças da laringe. Além da estimação dos parâmetros LF, no domínio do tempo (parâmetros T), a forma de onda da derivativa glotal também pôde ser quantificada através dos parâmetros identificados na literatura por parâmetros R (Rd, Ra, Rk e Rg), parâmetros quocientes Q (SQ, OQ, CQ, AQ e NAQ), parâmetros B1 e B2 que são as extensões de bandas do pulso derivativo LF, e o parâmetro ece, que relaciona os parâmetros β e Ta. Os parâmetros B1 e B2 e ece apesar de serem propostos na literatura, não são encontrados resultados diferentes a essas duas medidas. Os resultados mostraram que os parâmetros B não foram confiáveis na discriminação entre as vozes, por outro lado, o parâmetro ece mostrou-se ser opção na discriminação entre as vozes normais, nódulo e Reinke. O objetivo deste trabalho é direcionar a atenção sobre o sinal glotal, estimando-o automaticamente mediante técnicas de PDS aplicadas ao sinal de fala, visando extrair parâmetros que identifiquem as condições normais e patológicas da laringe. Por fim foram propostos os parâmetros TRp e TRs, visando dissociar os efeitos de primeira ordem dos de ordem superior na fase de retorno do pulso glotal com a finalidade de estimar a real não-linearidade do sub-sistema glotal, retratando as condições normais e patológicas da laringe. Por fim foram propostos os parâmetros TRp e TRs, visando dissociar os efeitos de primeira ordem dos de ordem superior na fase de retorno do pulso glotal com a finalidade de estimar a real não-linearidade do sub-sistema glotal, retratando as condições fisiológicas do movimento das pregas vocais. Com um nível de confiança de 95%, o parâmetro de primeira ordem (TRp) é efetivo na discriminação do Edema de Reinke, porém mostrou-se ineficaz na detecção do nódulo. Em relação ao parâmetro de ordem superior, conclui-se que o TRs é um excelente detetor de vozes patológicas (nódulo e Edema de Reinke), porém não é capaz de discriminar as patologias.
Many researches has been conducted in digital signal processing (DSP) atempting to evaluate the physiological conditions of larynx. Acoustical parameters have been proposed to evaluate the glotal tract from voice signal. One technique proposed is the Liljencrants-Fant model (LF) developed to represent normal and pathologic conditions of the larynx. Those parameters compare favourably as far as real physiologic characteristic of vocal folds is concerned. So, a primary use of the model is the larynx pathologic identification. Beyond LF parameters estimation, (T parameters in the time domain), the waveform of glotal pulse derivative also can be quantified through, R parameters (Rd, Ra, Rk and Rg), quocient parameters (SQ, OQ, CQ, AQ and NAQ), B parameters (B1 and B2) that are band extension of the LF glotal pulse derivative and the ece parameter that in fact, is a relationship between β and Ta. Although proposed in the literature, no results are found, related to B and ece parameters. Our founds show that B parameters do not present good results in voice discrimination, however, ece parameter seems to be good option to discriminate normal voice, nodulo and Reinke edema. The main purpose of this work is to estimate the glotal signal from the voice signal using DSP techniques in order to obtain parameters that identifies the physiological larynx condition. In order to estimate the shape of return phase of glotal pulse, twoparameters have been proposed in this work. The first one evaluates the pulse (TRp, in other words, the first order component of the return phase. The second is responsible to evaluate superior orders components of the return phase (TRs), i.e, the non-linear component of the glotal pulse. With 95% of confidence level, TRp is effective in Reinke edema discrimination however it is inefficient for nodule e dection. By the other hand, the TRs parameter works well to detect pathologic voice however is unable to discriminated them.

Abstract:
Parametric uncertainty in blood flow simulations of cardiovascular systems has received little attention, although methods for blood flow simulation has been subject of many studies. This work presents the implementation and assessment of a method for one dimensional flow and pressure wave simulations in arterial networks with statistically distributed model parameters. The pressure and flow waves in the arterial system are characterized by means of cross-sectionally averaged 1D governing equations for mass and momentum, discretized with a MacCormack scheme (explicit and second order in time and space). The stochastic model considered is a combination of a generalized polynomial chaos with a stochastic collocation method and joined with the one dimensional model. The implementation is validated with the simulation of a single arterial bifurcation, which has been published by others previously, with a somewhat different approach. The assessment is completed with a sensitivity analysis of the wave dynamics, in particular reflected waves, in the systemic arterial tree in the context of ageing. The numerical simulations showed that the impact of model uncertainty in different compartments of the arterial tree on systolic and diastolic pressure peaks can be determined with the elaborated method. In particular, the uncertainty in material parameters of the aortic arch showed a strong influence on the pressure wave forms.

Abstract:
Persistence and patience are the keys to successful DBS programming. Several studies show that one of the most common causes of unsuccessful DBS therapy is an inadequately programmed IPG. Note that with the rapid increase in the types and manufacturers of DBS systems now and anticipated, it is difficult to make precise statements about stimulation parameters. The responsibility for choice of stimulation parameters, electrode configurations, and pulse trains lies solely with the programmer. Specific examples of stimulation parameters, electrode configurations, and pulse trains provided in this text are for informational and educational purposes only. Covered in this chapter are issues of battery life, the optimal time to program DBS, monopolar surveys, and programming to prevent adverse effects.

Abstract:
Symptoms of post-traumatic stress disorder (PTSD) often fail to resolve with psychotherapy, pharmacotherapy, or integrative medicine treatments. Given these limitations, there is a continued push to discover treatment methods utilizing novel mechanisms of action. Transcranial magnetic stimulation (TMS) offers a non-invasive and safe method of brain stimulation that modulates neuronal activity in a focal area to achieve excitation or inhibition, and may have utility for patients suffering from PTSD, although, to date, evidence of efficacy is limited. The TMS treatment can be varied to suit the needs of the patient by altering the selection of the specific treatment parameters, such as pulse frequency or stimulation intensity. The weight of evidence to date supports treatment of either the right dorsolateral prefrontal cortex or the medical prefrontal cortex. Coupling treatment with script based exposure therapies may also assist with potentiation of the extinction response. Ultimately, stimulation parameters may be related to secondary downstream effects, and thus current targets may indirectly reverse the underlying neuronal pathophysiology. Given that PTSD is a complex illness with a poorly understood pathophysiology, it often exists with other psychiatric comorbidities or TBI. As such, TMS could be an effective part of a comprehensive treatment program.

Abstract:
Imaging tools in preventive cardiology can be divided into imaging modalities to assess pre-clinical and clinical atherosclerosis and functional assessments of vascular function or vascular inflammation. To calculate the likelihood of pre-clinical atherosclerosis intima-media thickness as well as coronary calcium scoring are most frequently used. However, beyond these two there are other parameters derived by ultrasound and multi-detector computed tomography as well as magnetic resonance imaging and nuclear/molecular imaging which are discussed in the chapter. Functional tests include flow-mediated dilatation, pulse wave analysis, and the ankle-brachial index. In clinical research other invasive measurements such as intravascular ultrasound/virtual histology/elastography, optical coherence tomography as well as thermography are being used. However, their value in clinical prevention still needs to be established.
