Modeling of the vibrations caused by ball bearing defects
(2003)
In this study a shaft-ball bearing system is modeled in order to investigate the vibrations of ball bearings with running surfaces defects. Shaft and bearing was modeled as mass-spring system and balls were assumed have ...
Primary repair of a sternal cleft in an infant with autogenous tissues
(2003)
A cleft sternum is a rare congenital anomaly often diagnosed as asymptomatic at birth. Clinical outcome may be unfavorable when an associated anomaly, particularly an intracardiac anomaly coexists with the defect. Primary ...
Determination of rolling element bearing defects through vibration analysis
(2003)
Determination of rolling element bearing defects through the available vibration analysis method is studied in this paper. Rolling element bearing defect vibrations, vibration measurement and their analysis is briefly ...
A full adaptive observer for DC servo motors
(2003)
An adaptive observer estimating all parameters and load torque is proposed for DC servo motors. The observer uses no direct feedback but the adaptation schemes use current and speed measurements. Both the observer and ...
High-pressure phase transition in some alkali halides using interatomic potential model
(2003)
We have predicted the phase transition pressure in some alkali halides NaCl and KCl using an interatomic potential approach based on a rigid ion model. We have obtained phase transition pressures 28.69 and 2.4 GPa, ...
An adaptive observer for Lorenz chaotic system
(2003)
An adaptive observer design technique proposed for nonlinear systems have been successfully applied to the Lorenz system, which produces chaotic oscillations. This observer does not use any feedback directly. The feedback ...
Seminal vesicle cysts causing hemospermia in adult polycystic kidney disease (APKD)
(2003)
Introduction: A 42 year- old man with adult policystic renal disease admitted to Urology out-patient with men hemospermia without any other symptoms. Result: After detailed evaluation including transrectal ultrasonography ...
