Moving path following for unmanned aerial vehicles with applications to single and multiple target tracking problems

This paper introduces the moving path following (MPF) problem, in which a vehicle is required to converge to and follow a desired geometric moving path, without a specific temporal specification, thus generalizing the classical path following that only applies to stationary paths. Possible tasks that can be formulated as an MPF problem include tracking terrain/air vehicles and gas clouds monitoring, where the velocity of the target vehicle or cloud specifies the motion of the desired path. We derive an error space for MPF for the general case of time-varying paths in a two-dimensional space and subsequently an application is described for the problem of tracking single and multiple targets on the ground using an unmanned aerial vehicle (UAV) flying at constant altitude. To this end, a Lyapunov-based MPF control law and a path-generation algorithm are proposed together with convergence and performance metric results. Real-world flight tests results that took place in Ota Air Base, Portugal, with the ANTEX-X02 UAV demonstrate the effectiveness of the proposed method.info:eu-repo/semantics/acceptedVersio

A convoy protection strategy using the moving path following method

This paper considers the problem of convoy protection missions using a fixed-wing Unmanned Aerial Vehicle (UAV) in scenarios where the radius of the circular region of interest around the convoy is smaller than the UAV minimum turning radius. Using the Moving Path Following (MPF) method, we propose a guidance algorithmic strategy where a UAV moving at constant ground speed is required to converge to and follow a desired geometric moving path that is attached to the convoy center. Conditions under which the proposed strategy solves the convoy problem are derived. A performance metric that is proposed together with numerical simulation results demonstrate the effectiveness of the proposed approach.info:eu-repo/semantics/acceptedVersio

Assistive technologies as rights enablers

The Convention on the Rights of the Child and the Convention on the Rights of Persons with Disability establish the rights for all children. For some children, enjoying those rights depends on or is facilitated by assistive technology, that is, products adapted or designed for improving the functioning of disabled people and all services inherent to the selection, acquisition, and use of assistive products. This chapter reviews the definition of assistive technology and briefly describes assistive products categories to show the breadth of assistive products available. It then discusses children rights and how they can be mediated or moderated by assistive technologies. Some of the challenges and ethical issues of assistive technology provision for children are also examined.info:eu-repo/semantics/publishedVersio

Citizen Science and Biological Invasions: A Review

Biological invasions are among the most challenging ecological and conservation riddles of our times. Fortunately, citizen science projects became a valuable tool to detect non-indigenous species (NIS), document their spread, prevent dispersion, and eradicate localized populations. We evaluated the most undisputed definitions of citizen science and proposed that a combination of two of them is a better reflection of what citizen science has become. Thus, citizen science is any environmental and/or biological data collection and analysis, including data quality control, undertaken by members of the general public, as individuals or as organized groups of citizens, with the guidance and/or assistance of scientists toward solving environmental and/or community questions. With this review, we also assessed how citizen science has been advancing biological invasions research and its focus, by analyzing 126 peer-reviewed articles that used citizen science methods or data concerning NIS. Most of the articles studied terrestrial species (68%) and terrestrial plants were the most studied group (22.7%). Surprisingly, most first detection reports were of non-indigenous marine fish probably due to the constraints in accessing aquatic ecosystems which delays the detection of new NIS. Citizen science projects running over broad geographical areas are very cost-effective for the early detection of NIS, regardless of the studied environment. We also discuss the applicability and need to adapt the methods and approaches toward the studied ecosystem and species, but also the profile of the participating citizens, their motivations, level of engagement, or social status. We recommend authors to better acknowledge the work done by contributing citizens, and the putative limitations of data generated by citizen science projects. The outreach planning of citizen science projects is also evaluated, including the use of dedicated web platforms vs. pre-existent and disseminated web platforms, while discussing how such outreach actions can be maximized. Lastly, we present a framework that contextualizes the contributions of citizen science, scientific research, and regional and national stakeholders toward the integrated management of biological invasions.FCT: SFRH/BD/140556/2018/ UIDB/04326/2020info:eu-repo/semantics/publishedVersio

Guidelines for supporting children with disabilities' play: methodologies, tools, and contexts

All children want to play. This is also true for children with disabilities. Facilitating their engagement in play, whatever children’s capacities, is a central premise of people who view play as fundamental for their development and well-being. Play for the sake of play, just for recreational pleasure and enjoyment, without any secondary goal. In this book you’ll find guidelines to support children with disabilities’ play. They can be a useful tool for ensuring that children with disabilities can fully enjoy their right to play, for improving the quality of children’s play, enhancing their play satisfaction and participation, and reducing play deprivation. Written in a lay-person language, providing ready-to-use information, this book is for parents, teachers, rehabilitation professionals, toy manufacturers, policy makers and in general for all of those interested in the topic of play for children with disabilities. This publication results from the research and work of a transdisciplinary team, all participants in the COST Action “LUDI - Play for Children with Disabilities”.info:eu-repo/semantics/publishedVersio

Towards the development of the psychosocial impact of assistive devices scale for continence (C-PIADS)

BACKGROUND: Current outcome measures for continence management devices do not adequately address psychosocial impact. The PIADS is an assessment tool that has been shown to reliably predict the adoption and use of assistive technology devices, but it is not widely used for continence devices. OBJECTIVE: To explore whether the PIADS requires modification to address the particular needs of continence device users and to inform any subsequent item development. METHODS: The study used interpretive methods in which qualitative information from semi-structured interviews was combined with the findings from cognitive interviews for questionnaire pre-testing. A total of 40 participants in UK and Canada were interviewed. RESULTS: Few participants had difficulty in understanding or relating to the majority of PIADS items. Several items were not considered relevant to continence and some areas for potential new items were uncovered. Embarrassment and concealment of urinary incontinence from others were common topics. CONCLUSIONS: The PIADS appears to fundamentally address many, but not all, of the important psychosocial concerns of adults who have continence difficulties. A version for continence, the C-PIADS, will require modification of the PIADS and is likely to contain some new items
