Health-State Estimation and Prognostics in Machining Processes [PDF]
Failure mechanisms of electromechanical systems usually involve several degraded health-states. Tracking and forecasting the evolution of health-states and impending failures, in the form of remaining-useful-life (RUL), is a critical challenge and regarded as the Achilles' heel of condition-based-maintenance (CBM).

Estimating Health State Utility Values for Comorbidities [PDF]
A comorbidity is defined as the presence of at least one additional health condition co-occurring with a primary health condition. Decision analytic models in healthcare depict the typical clinical pathway of patients in general clinical practice and frequently include health states defined to represent comorbidities such as sequelae or adverse events.

Online State-of-Health Estimation for NMC Lithium-Ion Batteries Using an Observer Structure
State-of-health (SoH) estimation is one of the key tasks of a battery management system, (BMS) as battery aging results in capacity- and power fade that must be accounted for by the BMS to ensure safe operation over the battery’s lifetime. In this study,

Battery state-of-health estimation for mobile devices [PDF]
Insufficient support of electric current sensing on commodity mobile devices leads to inaccurate estimation of their battery's state-of-health (SoH), which, in turn, shuts them off unexpectedly and accelerates their battery fading. In this paper, we design V-BASH, a new battery SoH estimation method based only on their voltages and is compatible to ...

The Use of Mapping to Estimate Health State Utility Values [PDF]
Mapping functions are estimated using regression analyses and are frequently used to predict health state utility values (HSUVs) in decision analytic models. Mapping functions are used when evidence on the required preference-based measure (PBM) is not available, or where modelled values are required for a decision analytic model, for example to ...

State of Health Estimation of Li-ion Batteries Based on GWO-LSSVM
The algorithms currently applied to state of health(SOH) estimation require numerous data samples for training and the estimation effect is not good. To address this issue, this study proposed a least-squares support vector machine(LSSVM) algorithm based
