O protótipo refere-se à construção de um modelo que está em processo de teste para ser comercializado. Atualmente a forma mais difundida é a construção efetiva das peças, no entanto existe no mercado softwares que realizam essa atividade virtualmente. Assim, esse estudo tem por objetivo verificar a similaridade visual entre os protótipos virtuais e os produzidos no processo tradicional, tendo em vista caimento, forma e volume, para validação de novos projetos na indústria do vestuário. Para tanto, foi desenvolvida uma pesquisa exploratória, e como forma de abordagem do problema foram realizados quatro experimentos que compreendem a construção de protótipos pela técnica virtual e a manual. / This research discusses the practice of prototyping in the apparel industry. The prototype relates to the construction of a model which is in testing process to be marketed. Currently the most widespread form is the actual construction of the pieces, However there is software on the market that perform this activity virtually. Thus, this study aims to verify the visual similarity between the virtual prototypes and those produced in the traditional process, in order to trim, shape and volume for validation of new projects in the clothing industry. To this end, an exploratory research was conducted, and as a way of addressing the problem were conducted four experiments which include the construction of prototypes for virtual and technical manual.

Subject of this work is a development of an integrated software environment for mechanical design and check of shell and tube heat exchangers. Processes of mechanical design and checks well as software which perform these processes are broken down to basic methods and parts. Mechanical design is usually performed according to some standards. In this work, ČSN EN 13445 is used. This standard describes mostly design check calculations which can be easily algorithmized. On the contrary, design calculations are described to some extent in few simple cases and mechanical design of shell and tube heat exchanger has not been fully algorithmized yet. Subject of this work is design of software, which will be capable of automatically performing mechanical design from datasheet as an input. Based on breakdown of design and check processes, requirements for key software features are derived. Important part of presented work is design and implementation of key modules – data model of shell and tube heat exchanger, module for mechanical design check according to ČSN EN 13445. These modules form basis of the software which will be developed further in future work.

The city of Natal has about 120 gas stations, of which only has an environmental license for operation. Discontinuities in the offices were notified by the Public Ministry of Rio Grande do Norte to carry out the environmental adaptations, among which is the investigation of environmental liabilities. The preliminary and confirmatory stages of this investigation consisted in the evaluation of soil gas surveys with two confirmatory chemical analysis of BTEX, PAH and TPH. To get a good evaluation and interpretation of results obtained in the field, it became necessary three-dimensional representation of them. We used a CAD software to graph the equipment installed in a retail service station fuel in Natal, as well as the plumes of contamination by volatile organic compounds. The tool was concluded that contamination is not located in the current system of underground storage of fuel development, but reflects the historical past in which tanks were removed not tight gasoline and diesel / Dentre as atividades econ?micas potencialmente poluidoras que comprometem a qualidade das ?guas subterr?neas est?o os Postos Revendedores de Combust?veis. A cidade do Natal possui cerca de 120 postos de combust?veis, dos quais, apenas um possui licen?a ambiental de opera??o. Os postos em desconformidade foram notificados pelo Minist?rio P?blico do Rio Grande do Norte para realizarem as adequa??es ambientais, dentre as quais est? a investiga??o de passivo ambiental. As fases preliminar e confirmat?ria desta investiga??o consistiram na avalia??o de gases do solo com duas sondagens confirmat?rias para an?lises qu?micas de BTEX, HPA e TPH. Para obter-se uma boa avalia??o e interpreta??o dos resultados obtidos no campo, se fez necess?rio a representa??o tridimensional dos mesmos. Utilizou-se um software CAD para representar graficamente os equipamentos instalados em um posto revendedor de combust?vel em Natal/RN, assim como as plumas de contamina??o por compostos org?nicos vol?teis. A partir desta ferramenta foi poss?vel concluir que a contamina??o n?o est? localizada no atual Sistema de Armazenamento Subterr?neo de Combust?vel do empreendimento, mas reflete o hist?rico passado em que foram removidos tanques n?o estanques de gasolina e diesel
