Satellite Communications

This study is motivated by the need to give the reader a broad view of the developments, key concepts, and technologies related to information society evolution, with a focus on the wireless communications and geoinformation technologies and their role in the environment. Giving perspective, it aims at assisting people active in the industry, the public sector, and Earth science fields as well, by providing a base for their continued work and thinking

Biorefarmeries: Milking ethanol from algae for the mobility of tomorrow

The idea of this project is to fully exploit microalgae to the best of its potential, possibly proposing a sort of fourth generation fuel based on a continuous milking of macro- and microorganisms (as cows in a milk farm), which produce fuel by photosynthetic reactions. This project proposes a new transportation concept supported by a new socio-economic approach, in which biofuel production is based on biorefarmeries delivering fourth generation fuels which also have decarbonization capabilities, potential negative CO2 emissions plus positive impacts on mobility, the automotive Industry, health and environment and the econom

Social work with airports passengers

Social work at the airport is in to offer to passengers social services. The main methodological position is that people are under stress, which characterized by a particular set of characteristics in appearance and behavior. In such circumstances passenger attracts in his actions some attention. Only person whom he trusts can help him with the documents or psychologically

Science-based restoration monitoring of coastal habitats, Volume Two: Tools for monitoring coastal habitats

Healthy coastal habitats are not only important ecologically; they also support healthy coastal communities and improve the quality of people’s lives. Despite their many benefits and values, coastal habitats have been systematically modified, degraded, and destroyed throughout the United States and its protectorates beginning with European colonization in the 1600’s (Dahl 1990). As a result, many coastal habitats around the United States are in desperate need of restoration. The monitoring of restoration projects, the focus of this document, is necessary to ensure that restoration efforts are successful, to further the science, and to increase the efficiency of future restoration efforts

Beyond problem identification: valuing methods in a ‘system usability practice’

Historically, usability evaluation methods (UEMs) have been evaluated on their capability for problem identification. However, the relevance of this approach has been questioned for applied usability work. To investigate alternative explanations of what is important for method use a grounded theory of usability practitioners was developed (9 interviews from the website domain and 13 in the safety-critical domain). The analysis proceeded in bottom-up and top-down stages. The bottom-up stages produced insight from the data in an exploratory and inductive manner. This highlighted the importance of contextual factors and the need for system descriptions: UEM adoption and adaptation cannot be fully understood devoid of context. The top-down stages used Distributed Cognition and Resilience Engineering conceptual frameworks as leverage for exploring the data in a deductive manner. These were chosen for their functional descriptions of systems. To illustrate the importance of context we describe three models: 1) where previous research has highlighted the downstream utility of UEMs we expand the metaphor to consider the landscape through which the stream flows, where the landscape represents the project’s context; 2) where information propagation and transformation in a project is influenced by social, information flow, artefact, physical and evolutionary factors; and 3) where the functional couplings between parts of the system of usability practice can be monitored and managed to positively resonate with each other, thereby improving the performance of the system overall. The concept of ‘Positive Resonance’ is introduced to describe how practitioners adapt to the context to maximise their impact under constrained resources. The functional couplings are described in a functional resonance model of HCI practice. This model is validated by interviewees and other practitioners outside of the study. This research shows that problem identification is limited for valuing UEMs. Instead, functional couplings of UEMs should be considered to improve system performance, which influence UEM adoption and adaptation in practice
