The military has invested in the development of low light level and night imaging technologies to gain tactical advantages on the battlefield. Moreover, certain military activities such as night aviation maneuvers demand the most sophisticated night imaging devices. Unfortunately, as the frequency of use of night imaging devices increases, so has the number of accidents (Boyd, 1991). Many of these accidents have been attributed to the novel usage as well as the intrinsic limitations of night imaging devices. The present research examined the effects of target size, luminance contrast, and illumination level on visual target detection and recognition while using AN/AVS-6 night vision goggles. Vehicle silhouette targets were rear-projected on random screen positions under various levels of illumination, contrast, and size. The observer's task was to detect and recognize each target while viewing through night vision goggles. The results indicate that visual detection and recognition performance degrade with decreasing levels of illumination, contrast, and target size. The findings of this work can be used to optimize the usage of AN/AVS-6 devices. / Master of Science

Every architecure is being with life-force such as a plant who lives on the photosynthesis that need carbon dioxide + water + light energy, and provide oxygen in day time. On the contrary, Plants need oxygen and release carbon dioxide while they can not carry out the photosunthesis in night time. But both chemical reactions occurring on the same plant in different time in a day. People normally spend one-third of their for working in an office or studying in school, and their home is empty during the day time. People use the rest of their time on a dinner in restaurant outside, other activities or events; back to home to rest and nobody occupies commercial area in night time. Why can we not do all of life's events in the same building or place whenever we wish? / Master of Architecture

Como distintas pedagogias entram em funcionamento nos espaços-tempos noturnos da metrópole? Para responder tal questão, o objetivo principal desta tese consistiu em dar visibilidade às pedagogias que se configuram e operam na noite da cidade de Porto Alegre, RS, Brasil. Para tanto, a pesquisa tratou de investigar como determinados lugares públicos noturnos proporcionam condições que ensejam experiências de aprendizagem implicadas com o que denomino pedagogias da noite. Posicionada no campo dos Estudos Culturais em Educação e partindo de pressupostos teóricos acerca das transformações culturais destacadas por S. Hall, T. Eagleton, Z. Bauman e R. Williams, a pesquisa se insere nas discussões levantadas por autores como H. Giroux, S. Steinberg, E. Ellsworth, M. V. Costa. V. C. Camozzato e P. D. Andrade em torno da pluralização do conceito de pedagogia e de seus espaços de atuação. O primeiro movimento da pesquisa procurou mapear representações da noite no campo das Artes, bem como nas produções das Ciências Humanas e Sociais em que o tema tem sido objeto de estudo. Tal levantamento evidenciou diferentes olhares, tanto para a formação de imaginários noturnos quanto para a diversidade de experiências vividas na noite, sugerindo distintos modos de condução em seus espaços-tempos. O segundo movimento consistiu nas saídas de campo em que o pesquisador-flâneur traçou rotas noturnas na região central de Porto Alegre. Os lugares noturnos selecionados foram três viadutos, duas ruas de um bairro boêmio e um grande parque da cidade. A pesquisa fez uso de uma metodologia de investigação híbrida, utilizando procedimentos inspirados na “etnografia pós-moderna” praticada por S. Gottshalk, na técnica da “observação casual” descrita por Lorite García e na “metodologia polifônica” adotada por M. Canevacci. O corpus de análise foi composto a partir das observações e registros das práticas sociais noturnas e dos relatos de sujeitos abordados nos lugares investigados. Viver na solidão, apegar-se aos pertences pessoais e protegê-los, assim como a desconfiança, resultam de aprendizagens daqueles que habitam nos viadutos à noite. Nas ruas boêmias, a adoção de formas estéticas, os encontros e a busca de relacionamentos afetivos são comportamentos aprendidos nas pedagogias da noite. Aprender a conhecer as intenções do outro pelo uso de “táticas” e “habilidades” realçaram-se como experiências no convívio laboral noturno. Comum a todos os lugares e relatos, evidenciaram-se experiências em que o medo e a insegurança promovem aprendizagens para a proteção na vida urbana noturna. Autores como R. Sennett, M. Canevacci, M. Maffesoli, Yi Fu-Tuan, M. Certeau, J. Larrosa e D. W. Winnicott embasaram as discussões analíticas. A relação do “eu” com o outro e com o lugar foi identificada como linha mestra das experiências de aprendizagem desenvolvidas por meio das condições exteriores e de como são interiorizadas pelos sujeitos. Intrínsecos aos modos de viver e aprender, esses movimentos de “exteriorização” e “interiorização” permitiram visualizar como as pedagogias se configuram e operam na noite. Funcionando como movimentos de articulação, as pedagogias da noite ensejam experiências em que os sujeitos aprendem tanto a conduzir quanto a conduzir-se e serem conduzidos nas situações e condições que determinados lugares noturnos da metrópole proporcionam. / How different pedagogies work in the metropolis nocturnal time space? In order to answer this question, the main objective of this thesis consists of give visibility to the pedagogies that are configured and operate in the night of Porto Alegre city, RS, Brazil. Therefore, the research sought to investigate how certain nocturnal public places provide conditions that entice learning experiences implied with what I call pedagogies of the night. Inscribed in the field of Cultural Studies in Education and based on theoretical assumptions about the cultural transformations highlighted by S. Hall, T. Eagleton, Z. Bauman and R. Williams, the research is inserted in the discussions raised by authors such as H. Giroux, S Steinberg, E. Ellsworth, MV Costa. V. C. Camozzato and P. D. Andrade around the pluralization of pedagogy concept and its spaces of acting. The first research movement pursued to map the representations of the night in the Arts field, as well as in the productions of Social and Human Sciences in which the subject has been object of study. This collection evidenced the different views, both for the nocturnal imaginaries formation and for the diversity of experiences lived at night, suggesting different modes of conduction in their time-spaces. The second movement consisted of field outing in which the researcher-flâneur traced nocturnal routes in the central region of Porto Alegre. The selected night spots were three viaducts, two streets of a bohemian neighborhood and a large city park. The research used a hybrid research methodology, utilizing procedures inspired by the "postmodern ethnography" practiced by S. Gottschalk, by the "casual observation" technique described by Lorite García and by "polyphonic methodology" adopted by M. Canevacci (2005). The corpus of analysis was composed from the observations and records of the nocturnal social practices and the subject’s reports approached in the investigated places. Living in solitude, clinging to personal belongings and protecting them, as well as the distrust, result as learnings of those who inhabit viaducts at night. In the bohemian streets, the adoption of aesthetic forms, the encounters and the search for affective relationships are behaviors learned in the pedagogies of the night. Learning to know each other's intentions through the use of "tactics" and "abilities" have been emphasized as experiences in the life at night. Common to all places and reports, there have been experiences in which fear and insecurity promote learning for protection in the urban night life. Authors like R. Sennett, M. Canevacci, M. Maffesoli, Yi Fu-Tuan, M. Certeau, J. Larrosa and D. W. Winnicott supported the analytical discussions. The relation of the "self" to the other and with the place was identified as the main line of learning experiences developed through external conditions and how they are internalized by the subjects. Intrinsic to the ways of living and learning, these movements of "exteriorization" and "interiorization" allowed to visualize how the pedagogies are configured and operate at night. Functioning as articulation movements, the pedagogies of the night provide experiences in which the subjects learn to drive and conduct themselves as well as to be conducted in the situations and conditions that certain metropolis nocturnal places provide.

The requirement to operate vehicles in low light and/or night environments whilst wearing night vision goggle (NVG) systems has become increasingly common during military operations. There is very limited research investigating injury risks associated with these systems during ground vehicle collisions. This study examined the injury risks associated with wearing the Australian Defence Force - Enhanced Combat Helmet (ECH) and NVG system, in frontal vehicle collisions. This project consisted of two components: (1) crash tests using a sled and (2) numerical simulations of impacts. Four dynamic sled tests were conducted using a 50th percentile, male, Hybrid III dummy positioned on a rigid seat. Frontal impact tests were performed at a 40 km/h change in velocity (*v) and 20 g deceleration. The test configurations were as follows: (a) Base; (no helmet or additional equipment); (b) ECH; and, (c) ECH and NVG. Condition (c) was carried out twice, to determine repeatability. The sled test protocols were reconstructed precisely with the numerical simulation package MADYMO and the simulations were shown to correlate well with the experimental results. Using this validated model, four parametric studies were undertaken to assess the influence of counterweights, seat cushion, seatbelt pre-tensioner, and the vehicle's *v and acceleration on injury risks. The study found that neck loads were within acceptable limits, with the exception of the neck extension moment, which was exceeded for all NVG conditions. Based on the parametric studies, no major improvements were observed in the neck extension moments with the use of counterweights or a seat cushion. In contrast the use of a seatbelt pre-tensioner was observed to decrease greatly this neck injury risk in certain scenarios. The study also identified that a *v of 15 km/h and peak acceleration of up to 14 g were required to keep the neck extension moment below the prescribed injury criteria. However, the high neck extension moment values may have been partially attributable to the stiff Hybrid III neck. This study identified a possible injury mechanism for soldiers using the ECH and NVG system during specific impact scenarios. The method applied in this project was designed to be repeatable.
