ADAM : aide au duel aerien moderne : theorie des jeux differentiels et programmation symbolique appliquees au probleme de l'Amraam

Le developpement de nouveaux missiles a moyenne distance du type Mica/Araam accroit le nombre de phases d'un duel aerien et introduit de nouvelles strategies de tir et d'evasion plus complexes. Nous presentons d'abord les duels a moyenne distance avant de les etudier sous la forme de sous-jeux differentiels. Puis nous expliquons comment developper un systeme d'aide a la decision grace a des simulations realisees avec des systemes experts utilisant les barrieres de sous-jeux differentiels

Solvability sets in pursuit problem with two pursuers and one evader

The paper deals with a differential game with two pursuers and one evader. Dynamics of each object is described by a stationary linear system of a general type with a scalar control. The payoff is the minimum of two one-dimensional misses between the first pursuer and the evader and between the second pursuer and the evader. The misses are calculated at the instants fixed in advance. A method is described for constructing the level sets of the value function (i.e., the solvability ones for the game under consideration). For the case of "strong" pursuers, the optimal strategies are described. Results of simulations are given. The zero-sum game investigated can be useful for the research of the final stage of a space pursuit, where two pursuing objects and one evader are involved. © IFAC

Health, community and development : towards a social psychology of participation

Population ageing is one of the major contemporary issues facing societies across the world. Originally framed as a major social and economic challenge, demographic ageing is now beginning to be seen as offering huge potential to individuals as well as to their communities. It is this positive potential that we explore in this issue by utilising two key disciplinary approaches—social gerontology and social/community psychology. In this introduction, we argue that focus on only one or the other of these perspectives is limiting. Instead, a more critical approach is needed that incorporates the strengths of both disciplines in order to build a more complete and stronger understanding of ageing and community. Thus, a focus on social gerontology highlights ageing issues and explores the diversity of older people and their interactions with community. By incorporating a social/community psychology approach, there is potential to complement this body of work through a deeper level of analysis around community, as well as individual and relational dimensions. The result is a special issue that brings together these two perspectives to address some of the shortcomings of approaching ageing through solely one disciplinary lens

Older adults experiences of rehabilitation in acute health care

Rehabilitation is a key component of nursing and allied healthcare professionals’ roles in most health and social care settings. This paper reports on stage 2 of an action research project to ascertain older adult's experience of rehabilitation. Twenty postdischarge interviews were conducted and the interview transcripts were analysed using thematic content analysis. All older adults discharged from an acute older acute rehabilitation ward to their own homes in the community were eligible to participate. The only exclusion criterion was older adults who were thought to be unable to give consent to participate by the nurse in charge and the researcher. Whilst 92 older adults were eligible to participate in this research study, only 20 were interviewed. The findings from this study suggest that older adults valued communication with health professionals but were aware of their time constraints that hindered communication. This study suggests that both nurses and allied health professionals are not actively providing rehabilitative services to promote health and well-being, which contradicts the focus of active ageing. Furthermore, there was evidence of unmet needs on discharge, and older adults unable to recall the professions that were involved in their interventions and the rationale for therapy input. It is suggested that further research is needed to explore the effectiveness of allied health rehabilitation in the acute setting. This study highlights the need for further research into older adults’ perceptions of the rehabilitation process in the acute setting
