Abstract
Depression and loneliness among the elderly are one of the biggest problems affecting the world population. This leads to elderly isolation which is a major risk factor for suicide. Moreover, if isolation is coupled with physical illness and incapacitation, such a risk increases exponentially. To fight back this problem, roboticists have been proposing solutions to autonomously monitor, support and even promote physical activities among the elderly. Nevertheless, those appear as very high-cost and complex solutions that require an advanced technical expertise. Recent off-the-shelf solutions, such as the well-known NAO robot, emerged as possible alternatives. An extension to the NAO robot, denoted as RIA, is being developed at the Engineering Institute of Coimbra (ISEC). The RIA is not only built for a social interaction with the elderly but also as an autonomous tool to promote professional care through the analysis of health and environmental parameters. Therefore, the RIA robot is an adapted NAO low-cost platform equipped with several sensors that can measure different parameters like body temperature, blood pressure and heart rate. By validating this valuable platform, the foundations were laid for a whole new paradigm in elderly care. © 2013 IEEE.

Abstract
This paper is about the development of 3D simulators for supplementary instruction in professional training with complex learning tasks and material, human and economic constraints. We present a theoretical framework describing and explaining how a simulator can support the fundamental interaction dynamics in learning settings (interaction with reality, with others and with the learner himself. We describe the development of an actual 3D simulator (for installing the engine in an F-16 fighter aircraft) and present its next phases. We discuss how our theoretical framework fits and explains the development phases of a 3D simulator to meet the intended learning outcomes and how it can help in the development of simulators with similar purposes.

Abstract
Species distribution models (SDMs) studies suggest that, without control measures, the distribution of many alien invasive plant species (AIS) will increase under climate and land-use changes. Due to limited resources and large areas colonised by invaders, management and monitoring resources must be prioritised. Choices depend on the conservation value of the invaded areas and can be guided by SDM predictions. Here, we use a hierarchical SDM framework, complemented by connectivity analysis of AIS distributions, to evaluate current and future conflicts between AIS and high conservation value areas. We illustrate the framework with three Australian wattle (Acacia) species and patterns of conservation value in Northern Portugal. Results show that protected areas will likely suffer higher pressure from all three Acacia species under future climatic conditions. Due to this higher predicted conflict in protected areas, management might be prioritised for Acacia dealbata and Acacia melanoxylon. Connectivity of AIS suitable areas inside protected areas is currently lower than across the full study area, but this would change under future environmental conditions. Coupled SDM and connectivity analysis can support resource prioritisation for anticipation and monitoring of AIS impacts. However, further tests of this framework over a wide range of regions and organisms are still required before wide application.

Abstract
In this paper, some considerations about the stateof- the-art and the current trends in the design and mechanisms of robotic hands are reported and discussed. Several robotic hands with multiple degrees-of-freedom have been developed over the last two decades, mainly through the use of traditional means of action (e.g., electric actuators). This paper surveys the related work accomplished by the scientific community so far, focusing on the problems engendered by these often conflicting requirements, and the work that has been done in this area. Although there are many robotic hands projects, only a few have been addressing alternative technologies such as the use of Shape Memory Alloy.

Abstract
The present study aims: i) to translate and adapt the TOPS2 to the Brazilian context (semantic equivalence/conceptual and content validity) ii) to examine its psychometric properties (fidelity and factorial validity), and iii) to examine the effects of context, gender, type of sport, competitive level and age in the use of psychological skills. The sample consisted of 540 subjects (423 male and 117 female). The fidelity of the factors varied between 0.50 and 0.82. The results indicated the AFC a reduced version (39 items) of TOPS2, accepting covariances between residual errors of some items of the instrument, as the best structural representations of the data analyzed. Multivariate analysis revealed that the effects of context, gender, type of sport, competitive level and age were significant in the use of psychological skills. These results suggest that the TOPS2 presents psychometric properties for use in Brazilian athletes, although further studies are recommended.
