Para produzir este trabalho, foi realizada pesquisa de campo na cidade de Condado, além de outras pequenas cidades da região. O objetivo era identificar elementos e princípios da brincadeira do Cavalo Marinho que pudessem contribuir para o trabalho do ator do Teatro de Rua. Para isso, foi realizada uma observação aprofundada sobre a figura do Mateus do Cavalo Marinho, que se tornou a referência central desta pesquisa. Como um estudo de caso de recriação de aspectos do Cavalo Marinho em cena teatral, é descrito o processo de montagem do espetáculo "Gaiola de Moscas", do Grupo Peleja, baseado no conto do escritor moçambicano Mia Couto. Em busca de uma reflexão sobre as proximidades, diferenças e contágios entre brincadeira e teatro, este trabalho aborda as características de cada uma dessas modalidades artísticas. Com base nesta discussão, é formulado o conceito de Ator Brincante, que representa tanto o brincante de Cavalo Marinho, como o ator do Teatro de Rua, numa qualidade que combina estabilidade e instabilidade ao vivenciar um estado cênico com um repertório codificado e ao mesmo tempo disponível, aberto ao inesperado. / Abstract: This thesis investigates the Street Theatre and the Cavalo Marinho ("Sea Horse"), a popular play from the "Zona da Mata" in the northern hinterland of the State of Pernambuco, Brazil. To conduct this study, field work was carried out in Condado city and other nearby small towns and villages. The main goal was to identify elements and distinctive features of the play-acting that can contribute to the Street Theatre actor's work. To this intent, the character of Mateus ("Matthew") was chosen as the central reference for this study and was observed and analysed in depth. As a case study of recreating aspects of the Cavalo Marinho in a theatre play, I describe the development of "Gaiola de Moscas" ("The Fly Cage"), a play based on a short story by Mia Couto, a writer from Moçambique, and created by the Peleja group. To contemplate the similarities, differences and exchanges between popular play and theatre, this study analyses the features of these two artistic modes. Based on this discourse, I elaborate the concept of "Ator Brincante" ("playing actor") which represents simultaneously the Cavalo Marinho player and the Street Theatre actor, combining stability and instability in a scenic condition where a codified repertoire is also constantly open to the unexpected. / Mestrado / Mestre em Artes

Efficient and accurate sensing of various parameters is needed for numerous applications. In this regard, different categories of sensors play a significant role and different applications require diverse sensing mechanisms owing to the operating conditions and field constraints. Among the several sensor methodologies available, optical fiber sensors have found significant attention, because of their advantages such as negligible foot print, small mass, immunity to Electromagnetic Interference, etc. In the category of optical fiber sensors, Fiber Bragg Grating (FBG) sensors have found importance in many fields such as health monitoring of civil structures, environmental monitoring involving gas & humidity sensing, monitoring parameters like pressure, tilt, displacement, etc. In the recent times, FBGs have found applications in biomedical, biomechanical and biosensing fields. A FBG is a periodic change of the refractive index of the core of a single mode optical fiber along its longitudinal axis. The periodic modulation in the index of refraction is obtained by exposing a photosensitive germanium-doped silica fiber to an intense UV laser beam. FBGs, in the basic form, can sense strain and temperature. However, in recent years, several newer sensing applications of FBGs have been demonstrated. Some of the main features of the FBG sensor which qualify them for diverse sensing applications are high sensitivity, large operational bandwidth, multiplexing & multi modal sensing capability, etc. In this thesis work, FBG sensor based devices have been developed for newer applications in bio-medical fields for the measurement of force, flow and temperature. Particularly, novel transduction methodologies have been proposed, in order to convert the measurand parameter into a secondary parameter that can be sensed by the FBG sensor. The evaluation of the force required for a spinal needle to penetrate various tissue layers from skin to the epidural space is vital. In this work, a novel technique for dynamic monitoring of force experienced by a spinal needle during lumbar puncture using Fiber Bragg Grating (FBG) sensor has been developed. The Fiber Bragg Grating Force Device (FBGFD) developed, measures the force on the spinal needle due to varied resistance offered by different tissue layers during its traversal. The effect of gauge of the spinal needle used for the lumbar puncture procedure affects the force required for its insertion into the tissue. The FBGFD developed, has been further utilized for a comparative study of the force required for lumbar puncture of various tissue layers with spinal needle of different gauges. The results obtained may serve as a guideline for selection of suitable gauge spinal needle during lumbar puncture minimizing post puncture side effects on patients. The pulmonary function test carried out using a spirometer, provides vital information about the functional status of the respiratory system of the subject. A Fiber Bragg Grating Spirometer (FBGS) has been developed which has the ability to convert the rate of air flow into a shift in wavelength that can be acquired by the FBG sensor. The FBGS can dynamically acquire the complete breathing sequence comprising of the inhalation phase, pause phase and exhalation phase in terms of the air flow rate along with the time duration of each phase. Methods are adopted to analyse and determine important pulmonary parameters using FBGS and compare these parameters with those obtained with a commercially available hospital grade pneumotachograph spirometer. Thermal imaging is one of the emerging non-invasive neuro-imaging techniques which can potentially indicate the boundaries of a brain tumor. The variation in tissue surface temperature is indicative of a tumor existence. In this work a FBG temperature sensor (FBGTS) has been developed for thermography of a simulated tissue using Agar material. The temperature of the embedded heater which mimics a brain tumor along with the surface temperature of the tissue model, is acquired using FBGTSs simultaneously. Further, the surface temperatures are studied for varying heater temperatures as well as varying positions of the heater in the simulated tissue model. To conclude, FBG based devices have been developed in this work, for applications in biomedical domain, with appropriate transduction methodologies for sensing different parameters such as force, flow and temperature.
