We use nonlinear model predictive control to procure a joint of mobility and transmission minimize total network communication energy use. The optimization problem is solved numerically in self-triggered framework, where the next update time depends on predicted state trajectory accuracy numerical solution. Solution must be accounted for any circumstance systems are run open-loop long stretches...

BACKGROUND Seligman's theory of causal attribution predicts that patients with a pessimistic explanatory style will have less favorable health outcomes. We investigated this hypothesis using self-reported hip pain and hip function 2- years after total hip arthroplasty (THA). METHODS Most THA patients had completed the Minnesota Multiphasic Personality Inventory (MMPI) during their usual clini...
