Texto completoIntroduction: Oral cancer is a severe condition with high mortality rate, in particular if diagnosed late. Brazil is one of the countries in the world with high prevalence and mortality from oral cancer and it is the fifth most common cancer there. An aid in early detection of oral cancer as an adjunct to health promotion is desirable.Purpose:The aim of this study was to evaluate the diagnostic accuracy of conventional oral examination and the use of multi spectral light (Identafi®) as an approach for early detection of potentially malignant or malignant lesions in the oral mucosa in a Brazilian population.Material and method:Screening of high-risk population in Goiania, Goias, Brazil, for oral potentially malignant lesions (PML) or malignant lesions (ML) as a selection phase. Patients collected from the screening were examined with multi spectral light (Identafi®) to evaluate diagnostic accuracy. Three observers independently assessed all lesions with Identafi® and the final decision if a lesion was present was taken in consensus. Inter observer agreement was calculated as overall agreement and as kappa value (κ). Biopsies were used as diagnostic reference standard.Results:Identafi® generated, from twelve biopsies, three true positive, five false positive, two true negative and zero false negative. Sensitivity was calculated to 0.29 and specificity was not possible to calculate since there were no false negative results.Inter observer agreement for the use of Identafi® was calculated as overall agreement and as kappa value (κ). The overall agreement for the three pairs of observers varied between 78-86% and κ-values between 0.46 and 0.60.Conclusion:The conclusion of this study is that Identafi® does not have any benefits over conventional oral examination in diagnostic accuracy for potentially malignant or malignant lesions in the oral mucosa. It might, however, be an aid for a dentists or oral surgeons that are unsure whether to take a biopsy or not. It can also aid the surgeon when taking a biopsy to take the most suspicious part of the lesion. There are not enough published evidence that Identafi® can discriminate between normal mucosa and PML or ML, and this study confirms previous results. The use of Identafi® as an aid in screening and examination for PML or ML needs further investigation.

Texto completoThis thesis consists of two relatively independent parts, the first part focuses on methods of temperature measurement using Multi-Spectral (passive optical pyrometry) methods, and the second on the Thermal Characterization by integral transforms at high temperature of orthotropic materials. In each of these two parts, methods / models developed were treated from a theoretical point of view, numerical and experimental. In the multi-spectral part, a method of temperature measurement to take into account a spectral variation of the overall measurement chain (including the emissivity) was introduced. Moreover, a method of determining the optimal wavelengths in the sense of minimizing the standard deviation of temperature, has been developed. Finally, it has also been shown that the optimal wavelengths for mono-spectral and bi-spectral measurements could be determined with similar laws to Wien's displacement law. In the Thermal Characterization part, different methods and models have been developed. The proposed methods perform the estimation of longitudinal and transverse diffusivities on all harmonics simultaneously. Furthermore, they allow overcoming the thermal coupling due to the presence of a sample holder, and / or making pseudo-local measurements of diffusivities. Finally, the concepts of correlation between parameters and duration of harmonics exploitability were also discussed.This thesis consists of two relatively independent parts, the first part focuses on methods of temperature measurement using Multi-Spectral (passive optical pyrometry) methods, and the second on the Thermal Characterization by integral transforms at high temperature of orthotropic materials.

Texto completoLes instal·lacions dil·luminació solen ser estàtiques i basades en indicadors visuals clàssics com la temperatura de color, la representació dels colors o els nivells d'il·luminació. Tanmateix, avui sabem que la llum també té una funció que no és propiament visual i que els arquitectes i dissenyadors haurien de començar a tenir en compte: la llum pot influir en el nostre estat d'ànim, modular la nostra atenció, regular la producció de melatonina o modificar els ritmes circadiaris. Tenir en compte totes les propietats espectrals de la llum és el primer pas per dissenyar entorns més sans i respectuosos amb la nostra biologia. Així, el disseny i desenvolupament de noves fonts de llum LED multicanal assequibles serà la tecnologia que permetrà un autentic canvi de paradigma espectral i començar a utilitzar la llum per a múltiples aplicacions. Aquest treball té com a objectiu facilitar aquesta transició proporcionant fonts de llum LED amb capacitat per generar qualsevol tipus de forma espectral. En una primera part, hem desenvolupat un sistema d'il·luminació multicanal orientat a un mercat d'investigació i recerca, i hem explorat nous dissenys i solucions per a un dispositiu més industrial amb l'objectiu de penetrar al mercat d'il·luminació general. Els dos esforços s'han materialitzat en dos dispositius òpticament i espectralment diferents: el sistema de llum SPECTRA TUNE LAB (amb un espectròmetre a l'interior i 10 canals LED diferents) i el sistema de llum VEGA 07 (amb un colorímetre i 7 canals LED diferents). En segon lloc, per poder crear qualsevol tipus de forma espectral, hem estudiat diferents algorismes heurístics implementats directament al micro-controlador de la lluminària o en un programari extern. L'algorisme desenvolupat de simulated annealing ha resultat ser el més ràpid amb una fidelitat espectral excel·lent. En tercer lloc, hem desenvolupat dos tipus de controladors òptics de llaç tancat amb dos sensors de llum diferents per evitar canvis de color i canvis espectrals degut a increments de la temperatura o degradació dels LEDs. Ambdós sensors, l'espectròmetre per l'SPECTRA TUNE LAB i el colorímetre pel VEGA 07, s'utilitzen per assegurar que la llum emesa romangui precisa i estable en tot moment, per a qualsevol espectre que vulguem generar. Finalment, demostrem com aquests dispositius es poden utilitzar per a diferents aplicacions oferint grans avantatges en comparació amb sistemes tradicionals. El nostre sistema d'il·luminació s'ha instal·lat a la unitat de cures intensives dhospitals (a l'Hospital Vall d'Hebron i a l'Hospital Clínic, a Barcelona), en entorns d'oficina (a ARUP, a Londres) o en sales de control 24 hores (a la sala de control de la refineria de Repsol, a Tarragona), entre d'altres

Texto completoThe aim of this study is to measure microscale temperature by optical way in the UV-visible range by photons counting using a cooled PMT. From the existing techniques advantages and disadvantages, this first part allows to understand the choices of this study. The second part shows and underlines the interest in working in short wavelengths (diffraction limit, measurement accuracy), in using the multi-spectral method to get rid of unknown parameters (e.g. emissivity) by choosing judicious working wavelengths, as well as the statistic laws to measure the photonic flux knowing its random emission. The third chapter presents the optical bench (optical microscope, photonic flux measurement facility…). A particularly attention is given to the design of the heated elements, which allow to calibrate the facility. The fourth part exposes the temperature results obtained through statistic laws. They validate the well-running of the facility, the microscopic area focusing, and the interest to model correctly the filters. Finally, measurement accuracy improvements (diffraction grating, multi-channel analyzer) and lower temperature measurement techniques (LIF, time-correlated method) are presented in the fifth part
