Empirical Physics‐Based Normal Behavior Modeling of Drive Train Temperatures With High‐Resolution Wind Turbine Operating Data

Wind Energy, EarlyView.
ABSTRACT The installed wind energy capacity increases every year. However, operation and maintenance costs still make up a considerable portion of the levelized costs of electricity. This costs can be greatly reduced by the application of suitable early fault detection methods. The supervisory control and data acquisition system of wind turbines is one

When Do Citizens Support Corrupt Politicians? The Trade‐Offs Between Corruption and Competence

Public Administration Review, EarlyView.
ABSTRACT The intriguing paradox of wide public disdain for corruption alongside popular corrupt politicians exists globally. By speaking to public ethics theory and rational choice theory, this study examines the trade‐off in which citizens tolerate corrupt officials in exchange for their competence to deliver public benefits.

Effect of Grease Lubrication on the Nonrepetitive Runout (NRRO) in Ball Bearing

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2008
Nonrepetitive runout (NRRO) is mainly caused by the diameter differences of balls contained in a bearing and the form errors of the raceway and balls. This paper deals with the effect of grease lubrication on NRRO.
