Sensors, 2022 In this article, we propose to determine the dynamic model of a squirrel-cage induction motor from a reduced amount of information. An adaptive observer is also built from this model in order to obtain a speed estimation and to perform rotor fault ...

An Improved PLL-Based Speed Estimation Method for Induction Motors through Harmonic Separation
Energies, 2022 The real-time speed estimation of induction motors (IMs) is important for the motors’ state monitoring and control. The utilization of rotor slot harmonics (RSHs) due to the inherent cogging effect is regarded as a promising way to realize the speed ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Pulmonary dysfunction and sleep abnormalities are common in children with sickle cell disease (SCD) and are associated with worse clinical outcomes. Whether spirometry abnormalities are associated with polysomnography (PSG) findings remains unclear.

Nonadaptive estimation of the rotor speed in an adaptive full order observer of induction machine [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2020 The article proposes a new method of reproducing the angular speed of the rotor of a cage induction machine designed for speed observers based on the adaptive method. In the proposed solution, the value of the angular speed of the rotor is not determined

KSCE Journal of Civil Engineering, 2014 In 2010 Highway Capacity Manual, one preferably determines free-flow speed by deriving it from a speed study involving the existing facility or on a comparable facility if the facility is in the planning stage. Many have used a ‘rule of thumb’ by adding 10 km/h (5 mi/h) above the posted limit to obtain free-flow speed without justification.

Prevalence and Trajectory of Household Material Hardship Among Children With Advanced Cancer
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background/Objectives Families of children with advanced cancer living in poverty experience inferior outcomes including poor parent mental health and worse child quality of life. Household material hardship (HMH: food, housing, transportation, and/or utility insecurity) is a modifiable poverty exposure—and potential intervention target—that ...
