This paper presents a simple but eecient way to nd a good initial trust region radius in trust region methods for nonlinear optimization. The method consists of monitoring the agreement between the model and the objective function along the steepest descent direction, computed at the starting point. Further improvements for the starting point are also derived from the information gleaned during...

Pervasive healthcare systems have the potential to revolutionize next generation medical applications and significantly improve the quality of healthcare services. In recent years, significant progress has been made in the development of a number of sensing and monitoring healthcare devices for clinical applications ranging from managing chronic diseases and acute diabetes to epilepsy and other...
