Correlations Of Some Tensile Properties For Various Grades Of Low Density Polyethylene
(
Qatar University
, 1994 , Article)
The tensile properties of nine different grades of low density polyethylene were measured, and the relationships resulting from the combination of different pairs of properties were analyzed. It was found that some properties ...
Nonlinear Adaptive Control Of A Permanent Magnet Stepper Motor
(
Qatar University
, 1994 , Article)
This paper considers adaptive position control of a permanent magnet (PM) stepper motor using exact linearization via static state-feedback. Physical outputs are chosen in such a way that the resulting closed-loop system ...
Flash Point For Binary Mixtures
(
Qatar University
, 1994 , Article)
Three flammable binary systems were studied for flash point as a function of liquid mixture composition: 1) decane/dodecane, 2) 0-xylene/cyclohexanol, and 3) 2-propanol/water. The vapor composition was estimated at each ...
