The secondary purpose was to determine the extent that gender issues and the transition age （50-65） are specifically addressed. Of 3,256 titles identified, 111 articles meet the inclusion criteria. Information was often indirect but addressed varying health domains that significantly influence transitional stages toward retirement and illustrating the burden of chronic comorbid health problems, unequal gender positions with differences in labour force participation, retirement pensions, and changing social dynamics. Few studies directly addressed the complex interaction of chronic health outcomes, psychological well-being, social and financial health as a significant paradigm in determining a successful transition into retirement. Needed are prospective longitudinal studies that measure predictors and outcomes of retirement transitioning along with qualitative studies that define the decision-making process. Given the substantial differential impact in respect to retirement risk factors and opportunities, there must be consideration in design and analysis for future high quality research.展开更多

The traditional leader/wingman formation control problem is considered, with focused attention on dealing with the input disturbance and parametric variations, both of which are intrinsic properties of the system that result in undesired control performance. A proportional-derivative control scheme based on nonlinear dynamic inversion is implemented as the baseline controller, and an L_1 adaptive controller is augmented to the baseline controller to attenuate the effects of input disturbance and parametric variations. Simulation results illustrate the effectiveness of the proposed control scheme.展开更多
