EDUCAÇÃO CORPORAL, ESCOTISMO E MILITARISMO (1908-1941)

São analisadas as influências militares no escotismo no período de 1908 a 1941, tendo como base a educação corporal proposta pelo movimento. Além de revisão bibliográfica mapeando estudiosos contemporâneos da história do escotismo, utiliza-se como base empírica livros, teses, artigos de periódicos especializados e de jornais publicados no período.Verificou-se que a ênfase na educação corporal por parte do escotismo se sustentou em um processo de aceitação e recusa da tradição militar em voga no início do século XX, impossibilitando tanto a mera vinculação, como o mero afastamento do escotismo em relação ao exército.

Optical Design of Zoom Hyper Spectral System

Hyper spectral imaging technology is widely applied in military scout and target recognition with imaging and spectral integration. To acquire different size image and field of view, a kind of zoom hyper spectral optical system is designed in this paper. The working spectrum is from 400nm to 1000nm. The detector size is 6.4mm×4.8mm. F# is from 3.5 to 5.6, and the focal length is from 28mm to 80mm. With consideration of the reasonable MTF requirement of back relay system and the visibility threshold of human eyes, which is the final receiver, the design requirements are analyzed. The initial structure is acquired by zoom method. After optimization, the image quality of every focal length and every spectrum meets the analyzed requirements. At last, to ensure the stable image during zoom process, the cam curve is calculated with image stable theory of dynamic optics.

Positioning and Utilizing Sensors on a 3-D Terrain Part I—Theory and Modeling

Positioning multiple sensors for acquisition of a given environment is one of the fundamental research areas in various fields, such as military scouting, computer vision, and robotics. In this paper, we propose a new model for the problem of sensor deployment. Deploying and configuring a set of given sensors on a synthetically generated 3-D terrain have multiple objectives on conflicting attributes: maximizing the visibility of the given terrain, maximizing the stealth of the sensors, and minimizing the cost of the sensors used. Since they are utility-independent, these complementary and conflicting objectives are modeled by a multiplicative total utility function, based on multiattribute utility theory. The total utility function proposed in this paper can also be adapted for various military scouting missions with different characteristics.

Precise matching of 3-D target models to multisensor data

This paper presents a three-dimensional (3-D) model-based ATR algorithm that operates simultaneously on imagery from three heterogeneous, approximately boresight aligned sensors. An iterative search matches models to range and optical imagery by repeatedly predicting detectable features, measuring support for these features in the imagery, and adjusting the transformations relating the target to the sensors in order to improve the match. The result is a locally optimal and globally consistent set of 3-D transformations that precisely relate the best matching target features to combined range, IR, and color images. Results show the multisensor algorithm recovers 3-D target pose more accurately than does a traditional single-sensor algorithm. Errors in registration between images are also corrected during matching. The intended application is imaging from semiautonomous military scout vehicles.

Zoonotic Infections in Military Scout and Tracker Dogs in Vietnam

Significant levels of antibodies indicative of a variety of zoonotic infections were demonstrated in sera collected from 64 U.S. military scout and tracker dogs after service in the Republic of Vietnam (RVN). Scrub typhus antibodies were found in 45% of the specimens, melioidosis in 19%, group B arbovirus in 49%, and leptospirosis in 62%. Only 38% of the seropositive reactions for leptospirosis could be related to overseas infections. Tests were conducted on paired sera obtained from 32 of the dogs before service in RVN. Significant increases in titer were demonstrated with scrub typhus, melioidosis, leptospirosis, plague, group B arbovirus, and Rickettsia canada antigens. After 2 to 6 months of service in RVN, 8 of 19 dogs developed antibody titers to at least one of four zoonotic diseases. Only 3 of 45 dogs with 7 or more months of service failed to develop antibodies to one or more of the agents. The serological findings pose questions on the potential epidemiological importance and veterinary significance of scrub typhus, group B arbovirus, leptospirosis, and melioidosis infections in dogs.
