Overview of coded light projection techniques for automatic 3D profiling

Obtaining automatic 3D profile of objects is one of the most important issues in computer vision. With this information, a large number of applications become feasible: from visual inspection of industrial parts to 3D reconstruction of the environment for mobile robots. In order to achieve 3D data, range finders can be used. Coded structured light approach is one of the most widely used techniques to retrieve 3D information of an unknown surface. An overview of the existing techniques as well as a new classification of patterns for structured light sensors is presented. This kind of systems belong to the group of active triangulation method, which are based on projecting a light pattern and imaging the illuminated scene from one or more points of view. Since the patterns are coded, correspondences between points of the image(s) and points of the projected pattern can be easily found. Once correspondences are found, a classical triangulation strategy between camera(s) and projector device leads to the reconstruction of the surface. Advantages and constraints of the different patterns are discussed

Relationship between siblings and psychological adjustment in adolescents:

This study evaluated the effect of parent-child relationship quality (acceptance and differential treatment) over dimensions of the quality of sibling relationships (warmth and conflict) and psychological adjustment in 69 adolescent sibling dyads. The effects of parent-child relationships were evaluated both at the individual and dyadic levels. In older siblings, the father-child relationship had a significant effect on both their perception of warmth in the sibling relationship and psychological adjustment. In younger siblings, there was a significant dyadic effect of the older sibling’s perceived acceptance by mother on their perception of warmth in the sibling relationship. Results are analyzed based on the literature and questions for future research are proposed.

Religion, Marketing and Market: An Adjustment in the Language of Faith

O presente trabalho se propõe fazer uma análise de categorias sociais que a primeira vista não tem proximidade, na verdade, podem, inclusive, parecer antagônicas. Trata-se das relações entre Religião, Marketing e Mercado. O trabalho se apóia num referencial teórico mais próximo das ciências sociais, todavia, considera a Religião, em sua expressão institucional –a igreja– como um empreendimento social, uma empresa dos tempos modernos. Procura demonstrar que, para aderir ao mundo moderno, plasmado pela idéia de competição e consumo da sociedade capitalista, a religião reorganizou sua linguagem para atender as exigências desses tempos, já considerados Pós-modernos. A análise é feita a partir do caso brasileiro que, como muitos paises da América Latina, acomodam no seu tecido social, as mais recentes expressões da religião cristã, em especial, os grupos evangélicos que pululam as periferias das grandes cidades desse  continente americano.

Seasonal adjustment and cointegration

El documento examina el efecto de filtros de ajuste en el tamaño y poder de prueba de cointegración que usan los residuales como pruebas ADF y PP, mediante procedimientos MonteCarlo y una aplicación empírica. Nuestros resultados indican que el uso de filtros distorsiona el tamaño y reduce el poder de estas pruebas.

An automatic correction tool for relational database schemas

A Web-based tool developed to automatically correct relational database schemas is presented. This tool has been integrated into a more general e-learning platform and is used to reinforce teaching and learning on database courses. This platform assigns to each student a set of database problems selected from a common repository. The student has to design a relational database schema and enter it into the system through a user friendly interface specifically designed for it. The correction tool corrects the design and shows detected errors. The student has the chance to correct them and send a new solution. These steps can be repeated as many times as required until a correct solution is obtained. Currently, this system is being used in different introductory database courses at the University of Girona with very promising results

Automatic generation of active coordinates for quantum dynamics calculations: application to the dynamics of benzene photochemistry

A new practical method to generate a subspace of active coordinates for quantum dynamics calculations is presented. These reduced coordinates are obtained as the normal modes of an analytical quadratic representation of the energy difference between excited and ground states within the complete active space self-consistent field method. At the Franck-Condon point, the largest negative eigenvalues of this Hessian correspond to the photoactive modes: those that reduce the energy difference and lead to the conical intersection; eigenvalues close to 0 correspond to bath modes, while modes with large positive eigenvalues are photoinactive vibrations, which increase the energy difference. The efficacy of quantum dynamics run in the subspace of the photoactive modes is illustrated with the photochemistry of benzene, where theoretical simulations are designed to assist optimal control experiments

Automatic diagnosis of voltage disturbances in power distribution networks

This thesis proposes a framework for identifying the root-cause of a voltage disturbance, as well as, its source location (upstream/downstream) from the monitoring place. The framework works with three-phase voltage and current waveforms collected in radial distribution networks without distributed generation. Real-world and synthetic waveforms are used to test it. The framework involves features that are conceived based on electrical principles, and assuming some hypothesis on the analyzed phenomena. Features considered are based on waveforms and timestamp information. Multivariate analysis of variance and rule induction algorithms are applied to assess the amount of meaningful information explained by each feature, according to the root-cause of the disturbance and its source location. The obtained classification rates show that the proposed framework could be used for automatic diagnosis of voltage disturbances collected in radial distribution networks. Furthermore, the diagnostic results can be subsequently used for supporting power network operation, maintenance and planning.

Automatic mass segmentation in mammographic images

Aquesta tesi està emmarcada dins la detecció precoç de masses, un dels símptomes més clars del càncer de mama, en imatges mamogràfiques. Primerament, s'ha fet un anàlisi extensiu dels diferents mètodes de la literatura, concloent que aquests mètodes són dependents de diferent paràmetres: el tamany i la forma de la massa i la densitat de la mama. Així, l'objectiu de la tesi és analitzar, dissenyar i implementar un mètode de detecció robust i independent d'aquests tres paràmetres. Per a tal fi, s'ha construït un patró deformable de la massa a partir de l'anàlisi de masses reals i, a continuació, aquest model és buscat en les imatges seguint un esquema probabilístic, obtenint una sèrie de regions sospitoses. Fent servir l'anàlisi 2DPCA, s'ha construït un algorisme capaç de discernir aquestes regions són realment una massa o no. La densitat de la mama és un paràmetre que s'introdueix de forma natural dins l'algorisme.

Hearing-aid volume control adjustment by deaf children

This paper examines hearing aid volume control adjustments by deaf children. Specifically the study looks at how accurately deaf children set the volume controls of their hearing aids, if deaf children are able to comprehend the effects of talker-microphone distance on stimulus intensity, and do deaf children use their hearing aids to monitor their own voices.
