Core loss (after-tax)* and core loss per share*, which exclude a USD13 million pre-tax unfavorable market-related mortgage servicing rights ("MSR") fair value adjustment, net of derivative losses related to MSRs, were USD19 million and USD0.
For the quarter ended September 30, 2016, core loss (after-tax) and core loss per share, excluding an USD13m pre-tax unfavourable market-related mortgage servicing rights (MSR) fair value adjustment, net of derivative losses related to MSRs, were USD19m and USD0.
Authors of [3]-[8] investigated analyses on iron losses and/or the equivalent core loss resistance for fixed rotor speed operation conditions.
Additionally, the P&C industry saw a higher level of favorable development of prior years' core loss reserve, with the combined ratio benefitting by 3.
The insurance industry saw a higher level of favorable development of prior years' core loss reserve (meaning, those not related to asbestos and environmental losses), with the combined ratio benifitting from 3.
To determine the equivalent circuit model of core loss and the magnetization phenomena a non-load test was perform at the low voltage side of each transformer circuit was performed.
Core losses are due to the main flux and leakage fluxes of the motor if the input voltage is to be constant, the core loss can also be constant.
With equivalent circuit methods, the performance of an induction motor at any load point is determined from its equivalent circuit coupled with six circuit parameters: stator winding, rotor winding, and core loss resistances as well as stator leakage, rotor leakage, and magnetizing reactances (Hughes 2006; Wildi 2002).
According to this derivation, in typical steel laminations, hysteresis loss at 60 Hz make up approximately 67% of the total core loss while the rest of the losses comprise of eddy current and other types of losses.
The aim of this study is to validate thyroid TMAs with whole sections as the gold standard using immunohistochemistry, to test our hypothesis that larger is better, and to study the effect of core size and grid density on core loss.
