Estudo para Utilização de Componentes de Suspensão de Motocicleta em Veículo Minimalista Urbano
No full textTCC (graduação) - Universidade Federal de Santa Catarina. Centro de Engenharias da Mobilidade. Campus Joinville. Engenharia Automotiva.A utilização de componentes de suspensão de motocicleta de baixo custo e grande volume de vendas mostra-se uma alternativa na construção de veículos minimalistas urbanos. Com o recente crescimento destes centros e constantes engarrafamentos nas cidades mais populosas, veículos menores, mais ágeis e econômicos se tornam cada vez mais competitivos e úteis frente aos automóveis, especialmente em trajetos diários curtos. As motocicletas, comumente utilizadas para este fim, possuem o aspecto negativo da vulnerabilidade dos ocupantes, por isso o veículo utilizado como base para o estudo possui a dinâmica de uma motocicleta (com duas rodas dispostas longitudinalmente ao veículo e inclinando-se em curvas), máximo de dois ocupantes, um à frente do outro, tornando-o mais esguio, e estrutura de carroceria fechada, o que aumenta a proteção e segurança em caso de colisões. É analisada a possibilidade de emprego do conjunto mola e amortecedor quanto ao conforto dos ocupantes pelas frequências naturais de vibração do sistema, pela massa máxima do veículo, e compressão e extensão dos componentes quando submetidos a esforços estáticos (do peso total do par veículo e piloto), e esforços dinâmicos por simulação em Matlab, pelo modelo de ½ veículo, da transposição do mesmo em ondulação transversal na via, resultando em valores máximos e mínimos de deslocamento, velocidade e aceleração da massa suspensa. Conclui-se que uma alternativa viável de aplicação, econômica e estruturalmente, é utilizar quatro conjuntos mola e amortecedor no veículo estudado, ao invés de componentes únicos ou de modelos mais caros de motocicleta.The use of motorcycle suspension components of low cost and high sales volume is shown an alternative construction of minimal urban vehicles. With the recent growth of these centers and constant traffic jams in the most populous cities, smaller vehicles, more agile and economical become increasingly competitive and useful compared to the car, especially for short daily journeys. Motorcycle, commonly used for this purpose, have the negative aspect of the vulnerability of the occupants, so the vehicle used as a basis for studying the dynamic features of a motorcycle (two wheels arranged longitudinally to the vehicle and leaning into curves), maximum of two occupants, one in front of the other, making it slimmer, and closed body structure, which increases the safety and security in case of collisions. Is analyzed the possibility of using the spring and damper set as comfort of the occupants by the natural frequencies of vibration of the system, the maximum mass of the vehicle, and compression and extension of components when submitted to static forces (the total weight of the vehicle and pilot pair), and dynamic efforts by simulation with Matlab, by the model of ½ vehicle, the transposition of the same by a speed bump transverse to the road, resulting in maximum and minimum values of displacement, velocity and acceleration of the sprung mass. It is concluded that a viable application, economical and structurally alternative is to use four sets of spring and damping in the vehicle studied, instead of single components or more expensive models of motorcycle
Construção de um ambiente de programação visual orientada por comportamentos
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-graduação em Ciência da ComputaçãoNa linguagem de programação de computadores deve-se obedecer a uma sintaxe textual durante o processo de programação e, em muitos casos, uma lógica imperativa, criando, desta forma, uma certa barreira para a construção de programas, principalmente por pessoas não especializadas, devido às dificuldades encontradas em aprender uma linguagem bem como as dificuldades em utilizá-la. O presente trabalho explora uma opção para amenizar os problemas enfrentados no processo de aprendizagem de programação buscando uma definição de um ambiente de programação visual baseado na noção de "comportamentos". Uma linguagem baseada em comportamentos é declarativa, o que a diferencia da maioria das linguagens visuais encontradas na literatura, que são do tipo imperativas, as quais possuem uma seqüência de instruções. Com isso, aqui foi abordado o tipo de linguagem de programação visual declarativa, onde se encontra uma relação entre os dados ou uma lista de declarações. Com as linguagens de programação visuais, não se elimina totalmente o texto, porém, por ser gráfica, este tipo de linguagem acaba proporcionando um maior conforto aos programadores em programar, tornando-se uma alternativa atrativa de programação. A definição proposta disponibiliza aos programadores um conjunto de comportamentos que podem ser atribuídos aos objetos para que estes exerçam suas funções no ambiente. Este ambiente tem sua construção feita sobre o Mundo dos Atores, uma ferramenta indicada para ser utilizada em disciplinas introdutórias de programação
Mammal collections of the Western Hemisphere: A survey and directory of collections
No full textAs a periodic assessment of the mammal collection resource, the Systematic Collections Committee (SCC) of the American Society of Mammalogists undertakes decadal surveys of the collections held in the Western Hemisphere. The SCC surveyed 429 collections and compiled a directory of 395 active collections containing 5,275,155 catalogued specimens. Over the past decade, 43 collections have been lost or transferred and 38 new or unsurveyed collections were added. Growth in number of total specimens, expansion of genomic resource collections, and substantial gains in digitization and web accessibility were documented, as well as slight shifts in proportional representation of taxonomic groups owing to increasingly balanced geographic representation of collections relative to previous surveys. While we find the overall health of Western Hemisphere collections to be adequate in some areas, gaps in spatial and temporal coverage and clear threats to long-term growth and vitality of these resources have also been identified. Major expansion of the collective mammal collection resource along with a recommitment to appropriate levels of funding will be required to meet the challenges ahead for mammalogists and other users, and to ensure samples are broad and varied enough that unanticipated future needs can be powerfully addressed. © 2018 The Author(s)

Terrestrial Parasite Tracker indexed biotic interactions and review summary.
The Terrestrial Parasite Tracker (TPT) project began in 2019 and is funded by the National Science foundation to mobilize data from vector and ectoparasite collections to data aggregators (e.g., iDigBio, GBIF) to help build a comprehensive picture of arthropod host-association evolution, distributions, and the ecological interactions of disease vectors which will assist scientists, educators, land managers, and policy makers. Arthropod parasites often are important to human and wildlife health and safety as vectors of pathogens, and it is critical to digitize these specimens so that they, and their biotic interaction data, will be available to help understand and predict the spread of human and wildlife disease.
This data publication contains versioned TPT associated datasets and related data products that were tracked, reviewed and indexed by Global Biotic Interactions (GloBI) and associated tools. GloBI provides open access to finding species interaction data (e.g., predator-prey, pollinator-plant, pathogen-host, parasite-host) by combining existing open datasets using open source software.
