11. IACS can trace its origins back to the International Load Line Convention of 1930 and its recommendations. 12. The third category, space-vector-based modulation, generates PWM load line currents that equal load line currents, on average. 13. The " cutoff point " is the point where the load line intersects with the collector voltage axis. 14. In 1906, laws were passed requiring foreign ships visiting British ports to be marked with a load line . 15. The intersections of the load line with the transistor characteristic curve represent the different values of " I" 16. Concerns regarding " Fitzgerald " s keel-welding problem surfaced during the time the USCG started increasing her load line . 17. Upon completion the ship is allowed to be operated for another year, and is issued a Load Line Certificate. 18. The " summer timber load line " is arrived at from the appropriate tables in the load line rules. 19. The " summer timber load line " is arrived at from the appropriate tables in the load line rules. 20. Any ship that returned to port with its " load line " below the water would be heavily fined.
