Flight dynamics system software development environment (FDS/SDE) tutorial

A sample development scenario using the Flight Dynamics System Software Development Environment (FDS/SDE) is presented. The SDE uses a menu-driven, fill-in-the-blanks format that provides online help at all steps, thus eliminating lengthy training and allowing immediate use of this new software development tool

Imagine your perfect park: how would it be? A qualitative study on the preferences, barriers and facilitators of green spaces' use by adolescents in a southern European urban context

Os espaços verdes são elementos essenciais das cidades. Estes espaços contribuem significativamente para a saúde e bem-estar dos adolescentes no meio urbano, constituindo modos de intervenção custo-efetiva para a redução das iniquidades em saúde e a transformação de cidades resilientes às alterações climáticas. No que concerne o planeamento e design dos espaços verdes urbanos, as necessidades e interesses dos adolescentes tendem a ser negligenciados. Foi objetivo deste estudo identificar facilitadores, barreiras e promotores de uso de espaços verdes urbanos pelos adolescentes da Área Metropolitana do Porto. Foi realizado um estudo qualitativo com recolha de dados através de grupos focais. Os participantes foram selecionados da coorte Geração XXI (G21) e foram estratificados de acordo com estatuto socioeconómico. Os dados foram analisados tematicamente, usando-se uma abordagem dedutivo-indutiva. A proximidade e multifuncionalidade dos espaços verdes urbanos foram os facilitadores de uso mais citados pelos adolescentes; enquanto que elevada pressão de visitantes, falta de vegetação e falta de manutenção foram identificados como importantes barreiras. Os adolescentes destacaram a necessidade de aumentar em número e tamanho os espaços verdes na Área Metropolitana do Porto, potenciando simultaneamente a sua multifuncionalidade através da provisão de equipamentos.Green spaces are an essential element in cities. They can significantly contribute to adolescents' health and wellbeing in the urban setting, being at the same time a cost-effective intervention to reduce health inequities and contributing to climate-resilient cities. Adolescents needs and desires regarding the planning and design of urban green spaces tend to be neglected. We aimed to identify facilitators, barriers and promoters of use of urban green spaces by adolescents in the Porto Metropolitan Area. A focus group design was used. Participants were selected from the Generation XXI cohort (G21) and were stratified according to their socioeconomic status. Data were analyzed thematically using a deductive-inductive approach. Proximity and multifunctionality of urban green spaces were the most cited facilitators of use, by adolescents; whilst high visitors' pressure, lack of vegetation and lack of maintenance were identified as important barriers. Adolescents enhance the need to increase the number and size of urban green spaces in the Porto Metropolitan Aera, while potentiating their multifunctionality by means of equipment provision

The One-Box Challenge: Providing a Federated Search That Benefits the Research Process

The one-box federated search of databases brings as many challenges as promises to database searching, especially in terms of adapting these systems to user needs and the effects this new mode of searching will have on users' research behaviors. This issue of “The Balance Point” presents several librarians with strong interests in reference and instruction, who tell the story of adapting a federated search system for their libraries and reflect upon how federated searching can change the way students do research and on the implications federated searching has on information literacy skills and the quality of results found

Virtual reality and program comprehension: application using spreadsheet visualisation

Program comprehension is an important function undertaken in the process of software maintenance. Compared to other research subjects, program comprehension has received little attention even though it is one of the biggest influences on a programmer's output. Research into aiding program comprehension has led to software visualisations, but these are mainly two-dimensional views and overload the viewer with information. With the advent of more powerful computers, virtual reality can be used to create three dimensional visualisations, in which the viewer is able to navigate freely. Spreadsheets were studied in this work on visualisation because programming languages are extremely complex and a model employing spreadsheets was developed. Spreadsheets offer many similarities to programming languages, for example, cell referencing and formulas in spreadsheets are similar to procedure calls, variable referencing and data manipulation in conventional programming languages. Common mistakes made in spreadsheets have been shown to be very difficult to locate, mainly because the spreadsheet user has a reduced ability to make hypotheses about the computational domain of a spreadsheet. Therefore, in order to address this shortcoming a visualisation model was developed to allow a spreadsheet user to be able to view both the problem domain (the what) and the computational domain (the how) simultaneously. A spreadsheet, a spreadsheet description language and a virtual reality system were the objects in the model, and a generator and translator were the links between those objects. Implementing the model indicated that spreadsheets could be visualised in virtual reality, and this technique was shown to improve the process of spreadsheet comprehension
