Pinho, Cátia; Oliveira, Ana; Oliveira, Daniela; Dinis, João; Marques, Alda. 2014. "LungSounds@UA Interface and Multimedia Database", International Journal of E-Health and Medical Communications 5, 1: 81 - 95. Abstract: The development of graphical user interfaces (GUIs) has been an emergent demand in the area of healthcare technologies.
Specifically for respiratory healthcare there is a lack of tools to produce a complete multimedia database, where respiratory
sounds and other clinical data are available in a single repository. This is essential for complete patients’ assessment and
management in research/clinical settings. Therefore, this study aimed to develop a usable interface to collect and organise
respiratory-related data in a single multimedia database. A GUI, named LungSounds@UA, composed by a multilayer of windows,
was developed. The usability of the user-centred interface was assessed in a pilot study and in an evaluation session. The
users testified the utility of the application and its great potential for research/clinical settings. However, some drawbacks
were identified, such as a certain difficulty to intuitively navigate in the great amount of the available information, which
will inform future developments. |

Objectives:The development of effective graphical user interfaces (GUIs) has been in an emergent
demand in healthcare technologies, for assessing, managing and storing patients’ clinical data. Nevertheless, specifically
for respiratory care there is a lack of tools to produce a multimedia database, where
the main respiratory clinical data can be available in a single repository. Therefore, this study reports on
the development of a usable application to collect, organise and store respiratory-related data in a single
multimedia database.
Methods:A GUI, named RIBS@UA, organised in a multilayer of windows was developed in MATLAB and
evaluated. The evaluation consisted of usability inspection (by two respiratory health professionals and
two system designers during the development of the prototype) and usability testing (by seven
physiotherapists).
Results:The users reported on the utility of the new application and its potential to be used in clinical/
research settings. It was also stated that RIBS@UA facilitates diagnosis/assessment and contributes to
the implementation of standardised interventions and treatment procedures. Nevertheless, some
drawbacks were identified and suggestions were given to improve the content of specific features in
the physiotherapy sessions window.
Conclusions:RIBS@UA interface is an innovative application to collect, store and organise the main
respiratory-related data, in a single multimedia database. Nevertheless, further improvements are still
recommended before thefinal implementation of RIBS@UA.

This paper reports the recording and analysis of an aerodynamic database of 51 words produced by four patients with Unilateral
Vocal Fold Paralysis. The vowel-fricative-vowel (VFV) boundaries were manually annotated and the mean absolute oral airflow
amplitude (OA), fundamental frequency (f0) and first formant intensity (IF1) were extracted from a 20 ms window in the steady
state of each phone. A case study approach to analysis of phonatory behaviour for the subjects is presented.
Significant differences were found between the absolute OA and IF1 for different phones. Large between subject variations
in absolute measures for OA and f0 were found. Relative values calculated from the difference in these parameters between
the fricative and the surrounding vowels phones show consistencyacross gendergroups and may be useful for characterising this
patient cohort in clinical practice for subjects of the same gender.

Oliveira, Ana; Pinho, Cátia; Monteiro, Sandra; Marcos, Ana; Marques, Alda. 2013. "Usability testing of a respiratory interface using computer screen and facial expressions videos", Computers in Biology and Medicine 43, 1: 2205 - 2213. ABSTRACT
Computer screen videos (CSV) and users’ facial expressions videos (FEV) are recommended to evaluate systems performance. However,
software combining both methods is often non-accessible in clinical research fields. The Observer-XT software is commonly
used for clinical research to assess human behaviours. Thus, this study reports on the combination of CSV and FEV, to evaluate
a graphical user interface (GUI).
Eight physiotherapists entered clinical information in the GUI while CSV and FEV were collected. The frequency and duration
of a list of behaviours found in FEV were analysed using the Observer-XT-10.5. Simultaneously, the frequency and duration
of usability problems of CSV were manually registered. CSV and FEV timelines were also matched to verify combinations.
The analysis of FEV revealed that the category most frequently observed in users behaviour was the eye contact with the screen
(ECS, 32±9) whilst verbal communication achieved the highest duration (14.8±6.9minutes). Regarding the CSV, 64 problems, related
with the interface (73%) and the user (27%), were found. In total, 135 usability problems were identified by combining both
methods. The majority were reported through verbal communication (45.8%) and ECS (40.8%). “False alarms” and “misses” did
not cause quantifiable reactions and the facial expressions problems were mainly related with the lack of familiarity (55.4%)
felt by users when interacting with the interface.
These findings encourage the use of Observer-XT-10.5 to conduct small usability sessions, as it identifies emergent groups
of problems by combining methods. However, to validate final versions of systems further validation should be conducted using
specialized software.

Pinho, Cátia M; Jesus, Luis M; Barney, Anna. 2012. "Weak voicing in fricative production", Journal of Phonetics 40, 5: 625 - 638. Abstract
Understanding of the production mechanisms of voiced fricatives lags significantly behind that of other phonemic categories
of speech. This paper presents a new voicing classification criterion to distinguish the voicing in fricatives from that of
their contextual vowels in VCV tokens: weak vs strong voicing. The criterion is based on the oral airflow, distinguishing
it from previous criteria based jointly on the acoustic and EGG signals. Aerodynamic and EGG recordings of four normal adult
speakers (two females and two males), producing a speech corpus of 9 isolated words with the European Portuguese (EP) voiced
fricatives /v, z, ¿/ in word-initial, -medial and -final position, and the same 9 words embedded in 42 different real EP carrier
sentences, were analysed. Fricatives were characterised in terms of oral airflow, fundamental frequency, first formant intensity
level and glottal open quotient in absolute terms and relative to the values found in their surrounding vowels. The voicing
during fricative production presented properties distinct from the voicing of the contextual vowels, leading to the development
of a classification criterion based on the relative amplitude of the oscillations in the oral airflow signal. This contributes
to distinguish voicing in fricatives from the modal voicing of the vowels.

"Optical Transforms and CGH for SDM Systems", Trabalho apresentado em 18th International Conference on Transparent Optical Networks (ICTON 2016), In Proceedings - ICTON 2016, Trento. Abstract: Spatial division multiplexing (SDM) systems are essential to overcome the increasing demand for higher bandwidth
data services. Nevertheless, SDM employment is challenging and complex impairments need to be addressed (e.g., crosstalk and
nonlinearities). The use of spatial light modulator (SLM) in core/mode division multiplexing is foreseen to improve channel
compensation, by using it as a diffractive device to reconstruct images from computer generated holograms (CGHs). The transparency
and passive nature of the application of optical transforms (e.g., Haar transforms (HT) fully in the optical domain) for compression/decompression
of data, may allow energy saving and processing capacity relief, by reducing redundant or negligible data.
In this study, the concept of combining HT and CGH to improve the processing/storing of high bandwidth demanding data associated
with SDM systems is presented. Exploring the implementation of parallel processing of 2D data through integrated optics, for
all-optical wavelet transforms and compression, and the use of CGH for spatial light modulation. |

Dinis, João; Oliveira, Ana; Pinho, Catia; Campos, Guilherme; Rodrigues, João; Marques, Alda. 2013. "Automatic wheeze and respiratory phase detectors to evaluate respiratory physiotherapy in LRTI: a preliminary study", Trabalho apresentado em Healthinf - 6th International Conference on Health Informatics, In Biomedical Engineering Systems and Technologies 6th International Joint Conference, BIOSTEC 2013, Barcelona. Abstract: Respiratory physiotherapy is a gold standard intervention for chronic respiratory conditions. However, its application
in acute respiratory diseases (e.g., LRTI) is not well established. The objective and reliable measurement of adventitious
lung sounds (ALS), such as wheezes, has the potential to contribute to respiratory physiotherapy evidence base. This paper
reports on the implementation of reliable and published automatic wheeze and respiratory phase detectors to assess wheezing
parameters pre/post respiratory physiotherapy treatment in patients with LRTI. Twenty patients with LRTI were randomly allocated
to control group, which received standard medication treatment, or experimental group, which received standard medication
plus respiratory physiotherapy treatment. Respiratory sounds were recorded in seven chest locations. Wheeze parameters, namely
occupation rate, main frequency, duration and type were obtained per respiratory phase. Wheeze occupation rate was statistically
significantly reduced in both groups following treatment (p<0.001). There was a greater reduction in wheeze occupation rate
in the experimental group reaching statistical significance for the inspiratory phase (p=0.019). This promising result indicates
the potential value of respiratory physiotherapy in LRTI. It also highlights the potential to use acoustic methods to establish
respiratory physiotherapy efficacy. |

Oliveira, Ana; Oliveira, Daniela; Pinho, Catia; Dinis, João; Neves, Joana; Marques, Alda. 2013. "Are adventitious lung sounds responsive to one session of respiratory physiotherapy?", Trabalho apresentado em European Respiratory Society Annual Congress 2013, In European Respiratory Journal - Annual Congress - Barcelona, Barcelona. Abstract:
Physiotherapists often use adventitious lung sounds(ALS), i.e., wheeze(Wh) and crackle(Cr), to monitor respiratory techniques
in acute obstructive(AO) and restrictive(AR) respiratory patients. ALS are responsive to bronchodilators however, evidence
regarding its usefulness in respiratory physiotherapy(RP) is scarce.
This study aimed to assess the responsiveness of ALS to one session of RP applied AO and AR patients.
RP included breathing retraining and airway clearance techniques. Sound recordings were acquired with a digital stethoscope
pre/post intervention, following the CORSA short-term acquisition guidelines. Computerised analysis was used to characterise
Wh(occupation rate and duration) and Cr parameters(number and two cycle duration-2CD) per breathing cycle(BC). Comparisons
were explored with Paired-Samples t-Tests(PASW 18.0).
Thirty outpatients(n=14 ¿, 55.2±17.8y), diagnosed with AO(exacerbation of COPD, acute bronquitis & asthma;n=18) and AR diseases(pneumonia;
n=12) were recruited.A significant decrease for Wh number (t=2.601 p=0.017) and occupation rate (t=2.533, p=0.020) per BC,
in all locations, was found for AR patients. In all chest locations, the number of Cr per BC, presented a significant increase
(t=-3.476, p=0.001) for AO and decrease (t=2.692, p=0.009) for AR patients. No significant differences were found for the
2CD.
Both Wh and Cr changed significantly in response to RP. Wh and Cr decrease in AR diseases may be indicative of more airways
opened after treatment. Cr increase in AO diseases, suggest movement of secretions to more central airways, allowing more
air to pass and leading airways to suddenly open. Further research is recommended.

Oliveira, Ana; Francesco, Sílvia D; Martins, Paula; Pinho, Catia; Marques, Alda. 2013. "Correlation between volumetric CT scans and lung function in lower respiratory tract infection", Trabalho apresentado em European Respiratory Society Annual Congress 2013, In European Respiratory Journal - Annual Congress - Barcelona, Barcelona. Abstract:
Computed tomography(CT) is currently the gold standard to monitor lower respiratory tract infection(LRTI), however CT is expensive
and involves considerable doses of radiation which prevents monitoring LRTI patients’ with the required frequency. As spirometry
is a simple procedure that measures inhaled and exhaled volume of air as a function of time, it may have potential to overcome
some of these difficulties. This study aimed to explore the correlation between spirometry and volumetric CT parameters in
LRTI.
Volumetric CT was performed in thirty-four outpatients with LRTI using a 64 MultiDetector CT. Tracheobronchial tree and lung
parenchyma were segmented applying Region Growing technique and Morphological Operations to obtain tracheobronchial and bronchial
(left and right) trees and lung parenchyma volumes(LPV). Forced expiratory volume in the first second percentage predicted
(FEV1pp), forced percentage predicted(FVCpp) and FEV1/FVC ratio were also collected. Correlations between volumetric values
and spirometry parameters were explored with Pearson/Spearman’s Correlation(SPSS 18.0) when appropriated.
Participants’ (52.9% females) mean age was 52.68±18.89 yrs. Tracheobronchial tree volume correlated significantly with FEV1pp(r=0.357,
p=0.038) and FVCpp(r=0.369, p=0.032). Left and right bronchial tree volumes also correlated significantly with FEV1pp(r=0.514,
p=0.02 and rs=0.507, p=0.02, respectively) and FVCpp (r=0.503, p=0.002 and rs=0.436, p=0.010, respectively). Regarding the
FEV1/FVC ratio, a negative and significant correlation with LPV was found (rs=-0.385, p=0.025).
These findings suggest that spirometry should not be performed alone to monitor LRTI as correlations found were mainly moderate.
Further research is needed to verify these results and explore other measures. |

Marques, Alda; Oliveira, Ana; Jácome, Cristina; Dinis, João; Pinho, Catia. 2013. "Agreement between real-time auscultation and computerised respiratory analyses", Trabalho apresentado em European Cystic Fibrosis Conference, In European Cystic Fibrosis Conference, Lisboa. Abstract:
Objectives: Inter-rater subjectivity has been reported when detecting adventitious lung sounds(ALS) with standard auscultation,
questioning its routine use as an outcome measure. Computerised respiratory analyses might overcome this limitation, however
the agreement between this approach and standard auscultation has been based in audio-recorded rather than real-time auscultation.
This study aimed to analyse the agreement between computerised respiratory analyses and health professionals’ real-time ALS(crackles
and wheezes) detection.
Methods: Seven outpatients with cystic fibrosis(aged 30±12yrs; 3 male) were treated with airway clearance techniques. Respiratory
sound recordings were collected before and after treatment, with a digital stethoscope following the CORSA guidelines(7 chest
locations). Simultaneously, the physiotherapist registered the number and position of each ALS in the breathing cycle (BC).
Validated algorithms were used for ALS and BC automatic detection. The agreement was examined using Kappa statistics.
Conclusion: Before treatment, the agreement in the number and position of crackles and wheezes in the BC was poor to fair(-.20<
Kappa< .30) for almost all locations(moderate for wheezes position at posterior locations, Kappa=.60). After treatment, agreement
in the number and position in the BC was poor to moderate for crackles(-.29< Kappa< .58) and wheezes(-.23< Kappa< .58). The
lack of agreement between the two methods enhances the need to develop real-time computerised respiratory analyses that can
be used as an outcome measure in the clinical setting. This would contribute for the respiratory physiotherapy evidence base
practice among cystic fibrosis.

Marques, Alda; Oliveira, Ana; Oliveira, Daniela; Pinho, Cátia. 2013. "Effects of Respiratory Physical Therapy in Patients with Lower Respiratory Tract Infection", Trabalho apresentado em American Thoracic Society International Conference, 2013, In A55. PULMONARY REHABILITATION: NON-CHRONIC OBSTRUCTIVE PULMONARY DISEASE AND ORGANIZATION OF CARE, Philadelphia. Abstract:
Methods: Patients with LRTI were recruited following hospital admission at the emergency department and treated with antibiotherapy
plus RPT(2). The RPT protocol was carried out 3 times per week for 3 weeks and included breathing retraining, airway clearance
techniques, thoracic mobility and flexibility exercises and aerobic training. Data were collected before and after the RPT
and included: the 6 minute walk test (6MWT) as the primary outcome measure to assess functional capacity(3), dyspnea and peripheral
oxygen saturation (SpO2) (at rest and after exertion) and lung function (forced expiratory volume in the first second percentage
predicted – FEV1pp, forced vital capacity percentage predicted - FVCpp and the ratio FEV1/FVC). Comparisons were explored
with Paired-Samples t Tests using the PASW® Statistics 18.0 software (SPSS Inc, Chicago, IL, USA). The significance level
was set at p<0.05.
Results: Nineteen patients (58.0% males, mean age 51.5±4.6 years old), diagnosed with pneumonia (63.2%), acute exacerbation
of a chronic obstructive pulmonary disease (18.2%), acute asthma (9.1%) and acute bronquitis (5.3%), enrolled in this study.
The six minute walk distance (6MWD) increased significantly after RPT (p=0.003) and in 47% of the patients, improvements were
above the minimal clinically important difference (4). Furthermore, after RPT significant improvements in FEV1pp (p=0.011)
and FVCpp (p=0.001), dyspnea at rest (p=0.001) and after exertion (p=0.020) and in SpO2 at rest (p=0.001), were observed.
Conclusion: Significant improvements in the perception of breathless, lung function and functional capacity of the LRTI patients
were found after RPT. These findings suggest that the implementation of RPT may be relevant to improve the health status and
functionality of these patients. Studies with larger samples and involving a control group are needed to confirm these findings. |

"Automatic Wheeze Detection and Lung Function Evaluation: a preliminary study", Trabalho apresentado em Healthinf - 6th International Conference on Health Informatics, In Biomedical Engineering Systems and Technologies 6th International Joint Conference, BIOSTEC 2013, Barcelona. Abstract: The automatic detection of wheeze offers the potential for diagnosing and monitoring respiratory diseases, e.g.,
lower respiratory tract infection (LRTI). By determining the relationship between wheeze detection and other lung function
data, it is possible to develop a more sensitive tool for detecting respiratory conditions. This pilot study aimed to: i)
explore the robustness of a time frequency wheeze detector (TF-WD) and ii) describe the correlation between wheezing and spirometry
parameters. Lung sounds and spirometry param-eters were acquired from six outpatients with LRTI (five with right lung infection).
Number, fundamental frequency and duration of wheezes were obtained through a TF-WD algorithm. The performance of the TF-WD
algorithm was evaluated by comparing its findings in 40 files with those annotated by two experts. Re-sults suggest that the
TF-WD algorithm is an ef¿cient and robust method for computerised wheeze detection in LRTI (SE=72.5%; SP=99.2%). Furthermore,
significant correlations were found between the percentage predicted of forced expiratory volume in 1 second and forced vital
capacity (FEV1pp and FVCpp) and wheeze duration at lateral (rs=-0.9, p=0.03) and posterior (rs=-0.9, p=0.01) right regions
respectively. These results support the use of pulmonary auscultation and spirometry to detect areas of obstruction in LRTI. |

Background: Computerised lung-sound analysis can be used to identify and quantify wheezes which are associated with pulmonary
diseases. However, this type of analysis requires further validation before it can be implemented routinely in the clinical
practice across different respiratory pathologies.
Objective : This pilot study aimed to validate a time-frequency wheeze detector (TF-WD) in the cystic fibrosis disease.
Methods: Recordings were made in a clinical setting from a stable cystic fibrosis adult outpatient with a digital stethoscope
following the CORSA guidelines. Several TF-WD algorithms were tested and the best performance was obtained with the Taplidou
et al. (2007) algorithm, which was validated in four sound files. The number, duration and type of wheezes were blindly analysed
independently by three experienced respiratory physiotherapists. Their evaluation was then compared with the automatic method.
The statistics accuracy of the wheezes detection was quantified through sensitivity, specificity and performance measures
using MatlabR2007b. True positives/negatives and false positives/negatives were counted by comparing each point of the sound
file.
Results: Inter-rater agreement between the physiotherapists was 96.9%. The sensitivity, specificity and performance of the
automated method were 77.2%, 98.4% and 87.1%, respectively.
Conclusion: The automated method tested shows sufficient reliability to continue the study and implement a future clinical
validation with a larger sample. Wheezes detection through computerised analysis can provide an objective measure to assess
and monitor cystic fibrosis patients, however further research is needed to validate the most robust algorithm.

"Performance of crackle detectors in cystic fibrosis and pneumonia: a pilot study", Trabalho apresentado em International Lung Sounds Association Conference, In 2011 International Lung Sounds Association Conference, Manchester. Abstract:
Study purpose: Computer aided lung-sound analysis (CALSA) [1] characterising adventitious lung sounds (ALS) can be an objective
and reliable method of identifying crackles [2], which are important indicators of lung disease severity. However, it is still
unclear which automatic detection algorithm offers the best performance; further validation is required to regularly apply
this method in clinical practice across different populations and respiratory pathologies. The main objective of this pilot
study was to test the behaviour of different crackle-detection algorithms in cystic fibrosis and pneumonia.
Methods: Four crackle-detection algorithms were implemented based on methods described in the literature: (A) Hadjileontiadis
and Rekanos [3]; (B) idem using Sevcik’s fractal dimension algorithm [4]; (C) Vannuccini et al. [5] and (D) Lu and Bahoura
[6]. Digital respiratory sound recordings were obtained following the CORSA guidelines [7] from four adult outpatients in
a clinical setting. Ten of these recordings (five of cystic fibrosis and five of pneumonia) were analysed using the implemented
algorithms. The recordings were independently annotated for crackles by three experienced respiratory clinicians. A reference
annotation (gold standard) was obtained through agreement by majority. The accuracy of the algorithms was assessed against
this gold standard. The chosen performance index was the harmonic mean (F-measure [8]) of sensitivity and precision. The criterion
applied to identify true positives (TP) was the coincidence of crackle maximum magnitude peak [9]. The assessment of performance
was completed by measuring the average computation time of each algorithm.
Conclusions: This study involved more demanding performance tests than usually reported in the literature, since the gold
standard was obtained through multi-annotator agreement to reduce annotation bias. (...). |

School: Modelling and Assessment of the Human Voice), In 9th International AQL Conference: Advances in Quantitative Laryngology, Voice and Speech Research, Erlangen. Introduction: Electroglottography (EGG) is a common method for providing noninvasive measurements of glottal activity. The
object of this study was to characterise EGG based parameters, specifically the open quotient (OQ), during fricative production,
and during the phones preceding and following the fricative in a carrier phrase. With the OQ measures we aim to quantitatively
establish if the relatively weak voicing during the fricative production may be differentiated from the stronger voicing of
the contextual vowel. Our long term goal is to understand the mechanisms by which voicing is initiated and maintained as a
guide to improving strategies for initiating and maintaining voicing in patients with laryngeal impairment such as unilateral
vocal fold paralysis (UVFP) (Pinho, Jesus, & Barney, 2009).
Methods: Data were collected from two adult female (JG and HV) and two adult male (LJ and RS) speakers of EP. None had reported
speech, language or hearing disorders, and all had normal vocal qualities. They were assessed by an experienced Speech and
Language Therapist using a standardised evaluation protocol (Jesus, et al., 2009). Speakers were recorded producing 51 utterances,
including 9 isolated words containing the EP voiced fricatives /v, z, Z/, in initial, medial and final word position, and
the same 9 words embedded in 51 different carrier sentences, that presented a variety of consonantal (taps, laterals, stops
and nasals) and vocalic (close, open front and back vowels) contexts in real EP sentences (only vowel-fricative-vowel sequences
were analysed). To analyse the EGG signal we built Matlab scripts based on the open source software “MOQ interface” (Henrich,
Alessandro, Doval, & Castellengo, 2004; Henrich, Gendrot, Michaud, & Tuan, 2005). We used the method “DEGG DECOM”, reported
as the one that presented the best results compared to OQ measurements derived from the inverse-filtered glottal flow (Henrich,
et al., 2004). (...). |

Biophysiology (ICALB), In International Conference on Voice Physiology and Biomechanics (ICVPB) - International Conference on Advances in Laryngeal
Biophysiology (ICALB), Madison, Wisconsin. Abstract:
The objective of this study was to characterise aerodynamic parameters of voiced stop consonants including slope of the stop
release, voice onset time (VOT), stop and release duration, and steady state characteristics of phones preceding and following
the stop. Aerodynamic and electroglottographic (EGG) recordings of four normal adult speakers (two females and two males),
producing a corpus of 9 isolated words with the European Portuguese (EP) voiced stops /b, d, g/ in initial, medial and final
word position, and the same 9 words embedded in 39 different real EP carrier sentences, were analysed.
The slope of the stop release was calculated from linear regression, using all flow signal points from the start to the end
of the release.
The slopes of the stops releases show no significantly different values for the three different places of articulation, but
there was a difference of approximately 10%, for all stops, between male and female speakers (Male: 78.9%(mean)8.5%(std);
Female: 69.0%(mean)11.5%(std)). An interpretation of these findings is that, as proposed by Higgins et al. (1998), glottal
area and resistance affect peak oral air flow.
Bilabial stops showed higher VOT values (-58.5ms to -64.6ms) than dental and velar stops (-49.0ms to -57.6ms). Female speakers’
VOT was higher than male speakers’ (Male = -49.5ms(mean)36.1ms(std); Female = -58.0ms(mean)28.8ms(std)). This difference was
also observed for stop durations (Male = 79.1ms(mean)28.6ms(std); Female = 92.8ms(mean)26.29ms(std)) and release durations
(Male = 28.6ms(mean)11.4ms(std); Female: 35.3ms(mean)14.8ms(std)). Dental stops’ duration (81.9ms(mean)28.3ms(std)) and release
duration (29.5ms(mean)12.3ms(std)) were lower than bilabial and velar stops’ duration (/b/: 88.2ms(mean)27.7ms(std); /g/:
87.8ms(mean)28.6ms(std)) and release duration (/b/: 34.3ms(mean)15.1ms(std); /g/: 35.5ms(mean)14.2ms(std)).
Analysis windows were defined in the three different production stages: stop closure (...). |

Abstract
The characteristics of steady state fricative production, and those of the phone preceding and following the fricative, were
investigated. Aerodynamic and electroglottographic (EGG) recordings of four normal adult speakers (two females and two males),
producing a speech corpus of 9 isolated words with the European Portuguese (EP) voiced fricatives /v, z, Z/ in initial, medial
and final word position, and the same 9 words embedded in 42 different real EP carrier sentences, were analysed. Multimodal
data allowed the characterisation of fricatives in terms of their voicing mechanisms, based on the amplitude of oral flow,
F1 excitation and fundamental frequency (F0). |

Abstract:
In this text we present a Bayesian system of auditory localisation in distance, azimuth and elevation using binaural cues
only; we focus mainly on implementation details and the calibration procedure, and present experimental results. This binaural
system is also integrated in a spatial representation framework for multimodal perception of 3D structure and motion — the
Bayesian Volumetric Map (BVM). This solution will enable the implementation of an active perception system with great potential
in applications as diverse as social robots or even robotic navigation. |

Abstract:
In this text we will present a novel solution for active perception built upon a probabilistic framework for multimodal perception
of 3D structure and motion — the Bayesian Volumetric Map (BVM). This solution applies the notion of entropy to promote gaze
control for active exploration of areas of high uncertainty on the BVM so as to dynamically build a spatial map of the environment
storing the largest amount of information possible. Moreover, entropy-based exploration is shown to be an efficient behavioural
strategy for active multimodal perception.

In this text we will briefly present motivations, theory and results for a Bayesian approach that models stereovision as a
probabilistic process in a log-spherical egocentric frame. This spatial configuration is in general agreement with what is
believed regarding how the brain represents space for fast active perception purposes. Consequently, it provides several advantages
over its Euclidean counterparts.

ABSTRACT: This work aims at testing some available deconvolution algorithms for constructing a 3-D view from a Z-stack of
wide field optical micrographs. Specifically, we test different algorithms for providing use-ful contrast in z-direction in
the demanding situation that the size of the object in the z-direction and that of the features (x-y plane) are of the order
of probe wavelength. Here, the concept of Point Spread Function, based on geometrical optics, is at the limit of its validity.
We have analyzed a Z-stack of images of erythro-cytes with basophilic stippling associated with pyrimidine 5'-nucleotidase
deficiency. The relative z-positions of dotted features can provide useful information to pathologist in understanding the
causes of the disease. Our tests on four algorithms show that despite the limiting conditions mentioned above we can obtain
an im-provement in the vertical discrimination and general contrast of the figure. . |

"Application of Spectral Imaging and Image Processing in the Study of a Pathology in Human Erythrocytes", Trabalho apresentado em Advanced Spectroscopies on Biomedical and Nanostructured Systems, In Advanced Spectroscopies on Biomedical and Nanostructured Systems, Cluj-Napoca. Abstract:
Microscopic observation of a peripheral blood smear is an essential part of the investigation of any blood disorder. Basophilic
stippling and other cytoplasmic inclusions are morphological anomalies of red blood cells associated with different hematological
diseases. Commonly used optical microscopic technology has a low resolution and does not allow for precise quantitative evaluation
of these changes. In this communication a spectral imaging technique developed by our group is described, which significantly
increases contrast. The high resolution digital images obtained with a TE cooled CCD camera are subsequently processed to
calculate parameters (por todos os parametros) like fractional area and average separation between dots. Samples from four
patients with blood disorders in witch the morphological anomalies previously described are import diagnostic findings were
studied: pirimidine 5'-nucleotidase (P5’N) deficiency, hemoglobinopathies Hb Sabine and Hb Génova, and ß thalassemia intermedia.
We show histograms of parameters obtained from a statistically significant number of red blood cells. Our work shows that
the techniques we have developed can be used to obtain quantitative data related with these pathological indicators of blood
disease. These measurements will be correlated with clinical findings and commonly used hematological and biochemical parameters
in order to evaluate their ability to further characterize these disorders and improve diagnosis and follow-up capabilities.
The versatility of our set-up allows for easy adaptation of this technology to the study of other blood disorders and to general
cytology research. |

"Scanning Raman Microscope for Biological Samples: Study of Human Erythrocytes and Other Cells", Trabalho apresentado em Advanced Spectroscopies on Biomedical and Nanostructured Systems, In Advanced Spectroscopies on Biomedical and Nanostructured Systems, Cluj-Napoca. Abstract:
Raman spectroscopy is a non-invasive technique to study the chemical structure of the specimen and thus is an attractive technique
to study the biological samples. In order to study the spatial variations in the chemical nature of the specimen of submillimeter
size, a synergetic combination of the microscope and spectrometer is necessary. In this communication we describe the system
that we have designed and built around a microscope that allows us to do laser scanning of the excitation spot. The Raman
spectra of micron size spots are collected in a sensitive linear array detector at the output port of a spectrometer. We describe
the details of the system, its performance characteristics as measured by latex and polystyrene microspheres for different
excitation wavelengths and provide a measure of the spatial resolution. Finally, we show the results obtained with a near
infrared excitation wavelength, 785nm on several biological samples. We have used the set-up to study in detail the Raman
Spectra map of single normal human red blood cell and compare it with that of a cell with pathology. |
