Increasing the complexity of lipoprotein characterization for cardiovascular risk in type 2 diabetes

European Journal of Clinical Investigation, Volume 54, Issue 8, August 2024.
Abstract The burden of cardiovascular disease is particularly high among individuals with diabetes, even when LDL cholesterol is normal or within the therapeutic target. Despite this, cholesterol accumulates in their arteries, in part, due to persistent atherogenic dyslipidaemia characterized by elevated triglycerides, remnant cholesterol, smaller LDL ...

A new air gap flux‐based technique to detect loss of field in synchronous generators

IET Electric Power Applications, Volume 18, Issue 5, Page 543-555, May 2024.
A new technique is proposed for loss of field (LOF) detection in synchronous generators (SGs). The proposed scheme employs the variations of SG angular velocity and load angle to reach this goal, while the mentioned parameters are estimated through air gap flux estimation.
