1. Improving skin picking diagnosis among Brazilians: validation of the Skin Picking Impact Scale and development of a photographic instrument
Abstract Background Skin picking disorder is a prevalent disorder frequently comorbid with depression and anxiety, which is underdiagnosed mainly by dermatologists. Assessment of skin picking disorder is based on instruments influenced by the awareness about skin picking disorder and comorbid symptoms. To date, there is no validated instrument for Brazilian

2. Metodología ad hoc para la observación de superficies de desgaste y fractura
ABSTRACT In the present work, a methodology of microscopic analysis and measurement of wear surfaces is presented, based on images made using digital processing techniques such as stitching and stac-king. The images are obtained from an ad-hoc and low-cost microscopic observation system, consisting of sample positioning and focus-elevation modules with micro

3. New numerical method for the photoelastic technique
The objective of this research is to find new equations for a novel phase-shifting method in digital photoelasticity. Some innovations are proposed. In terms of phase-shifting, only the analyzer is rotated, and the other equations are deduced by applying a new numerical technique instead of the usual algebraic techniques. This approach can be used to calcula

4. Contribution to the study of a non-invasive probe for measuring the water thickness in a core-annular flow / Contribuição ao estudo de um medidor não-invasivo da espessura da camada de agua em um escoamento anular oleo-agua
This work is a contribution to the study of a non-intrusive probe for measurement of the thickness of the water layer of a core-annular flow. A capacitive probe was built and its static performance was evaluated from tests executed in a specially designed bench-scale apparatus. In addition, evaluation of the dynamic performance was made possible from fluid-f

5. Fotogrametria e Antropometria direta da região mamária. / Photogrammetric and direct anthropometry of the breast region
The standard photography documentation has been used as a tool of morphology assessment, becoming a source of objective information when compared with the visual site. The importance of the measurements in the front part of the breast area is due to scientific and juridical aspects, being another auxiliary method of evaluation before and after surgery. The m

6. Protocolo de fotogrametria computadorizada na quantificacao angular da escoliose
The scoliosis is a three-dimensional deformation of the spine. It is a serious disease that can compromise vital organs like heart and lungs, in addition to influence the aesthetic and quality of life. His progression is generally associated with growth peak, getting in that case, the name of the adolescent idiopathic scoliosis (AIS). Thus, the pubertal peri

7. Monitoramento por dgps e análise dos processos erosivos da linha de costa na praia de Pirangi do Norte - Parnamirim / RN
Through out the course of a steady increase in search and recovery of space in the coastal zone, there is also an expanding concern about the erosion processes of this area. The main problem in coastal areas is that urbanization occurs in a disorderly fashion and unsustainable, further aggravating the problems of coastal dynamics. The study area of this work

8. Avaliação dos efeitos da hipertermoterapia por ultrasom associada a agentes antiangiogênicos no tratamento do tumor experimental de walker / EVALUATION OF THE HIPERTHERMOTHERAPY EFFECTS BY ULTRASOUND ASSOCIATED TO ANTIAGIOGENIC AGENTS IN THE TREATMENT OF WALKER EXPERIMENTAL TUMOR
The traditional methods of cancer treatment, like the chemotherapy and radiotherapy, even though they are effective in many types of tumours, they find frequently resistant neoplasic cells population, beyond presenting a low security margin to the patients. The hyperthermia use associated to the chemotherapy and radiotherapy are plenty mentioned as profitabl

9. Medida da qualidade de imagens de câmeras digitais usando entropia informacional. / Quality measurement of digital camera image using informational entropy.
This is an experimental work which uses the concept of informational entropy for digital image analysis. The researched literature shows that the informational entropy concept is used for image analysis, but the photographic equipment available in the market is not discussed. The aim of this work is to offer ,for photographers mainly, an experimental functio

10. Film thickness and wave velocity measurement using reflected laser intensity
The objective of this work is to develop a film thickness and velocity measurement technique using laser intensity measurement in liquid film flow. This technique was developed for annular flow studies, but it has been scarcely used due to the equipment's complexity, as compared with other techniques. The laser technique uses the reflection of the laser beam

11. Efficacy of physical therapy on cervical muscle activity and on body posture in mouth breathing children, eletromyographic evaluation and computerized photographic analysis / Eficacia da intervenção fisioterapeutica nos musculos cervicais e na postura corporal de crianças respiradoras bucais : avaliação eletromiografica e analise fotografica computadorizada
The Mouth Breathing Syndrome (MBS) has as main causes the craniofacial malformations, nasal or pharyngeal obstruction and, deleterious habits. The mouth breathing produces compensatory postural adaptation, especially on the head posture. Therefore, an interdisciplinary approach for the MBS has been recommended, not only considering the dentition, facial skel

12. Experimental validation of a 3-D vision-based measurement system applied to robot calibration
One of the problems that slows the development of off-line programming is the low static and dynamic positioning accuracy of robots. Robot calibration improves the positioning accuracy and can also be used as a diagnostic tool in robot production and maintenance. A large number of robot measurement systems are now available commercially. Yet, there is a dear
