Photoelastic determination of geometry factors for spur gear teeth
(1965)
Geometry factors for spur gear teeth were determined using photoelastic models of 20° full depth involute spur gear teeth. Seven models w ere made representing gears having 20, 25, 30, 40, 60, 80, and 125 teeth respectively, ...
An analysis of distributed lag in feedback control systems with general impedance termination
(1965)
Analytical methods of analysis for linear feedback control systems are extended to include distributed lag in its most generalized form (terminating impedance having both resistive and reactive components). Methods are ...
Investigations of the mechanisms of cross pollination in wheat and combining ability as indicated by forage production in hybrids of male sterile stocks and commercial varieties
(1965)
Average seed set in lateral florets of male sterile plants with T. timopheevi, Ae. caudata and Ae. ovata cytoplasms, cross pollinated by 45 wheat strains, ranged from 11.1 to 61.2, 4.3 to 57.5 and 1.6 to 35.9%, respectively. ...
Economic dispatch solution of an electric power network with optimum selection of generator bus voltages and transformer turns ratios
(1964)
A prime objective in a large electrical power network is that of scheduling the generation at various generating plants to supply the existing network loads and transmission losses while minimizing the total cost of ...
Effects of sublethal dosages of certain insecticides on eggs, larvae and adults of two species of Heliothis (Lepidoptera: Noctuidae)
(1965)
Topical treatments with endrin and Guthion compounds were applied to eggs, larvae and adults of the bollworm, Heliothis zea, and the tobacco budworm, Heliothis virescens. Endrin was much more effective on larvae of both ...
A study of the power angle concept of polyphase induction machines
(1965)
With the aid of field maps and the basic fundamental equations related to polyphase induction motors, a torque angle is defined on a vector diagram. The electromechanical torque developed by the rotor, the stator or input ...
