Broken Bar Fault Detection in IM Operating Under No-Load Condition
Advances in Electrical and Computer Engineering, 2016 This paper presents a novel method for broken rotor bar detection in a squirrel-cage induction motor (IM). The proposed method applies a single-phase AC voltage as a test signal on motor terminals, resulting in a stator backward-rotating magnetic field.

Measurement of Coastal Currents
Coastal Engineering 1968, 1968 Getting a drift buoy into and over the surf zone in rough weather has always been a problem. A cheap, cold propellant rocket launcher using either compressed air from aqua-lung bottles or liquid carbon dioxide is admirably suited for hurling drift bottles to ranges of over 1,000 feet.

Cholesterol measurement and current guidelines [PDF]
Vnitřní lékařství, 2022 The concentration of total cholesterol has so far been part of the SCORE tables for estimating the risk of cardiovascular events; in the new SCORE2 tables, it has already been replaced by non-HDL-cholesterol. Total cholesterol continues to serve as a guide for the presence of dyslipoproteinemia and is necessary for the calculation of LDL-cholesterol ...
