Initial results on magnetic flux leakage (MFL) diagnosis device
(Universiti Malaysia Perlis, 2010-06-09)
Magnetic flux leakage (MFL) is
among the famous and expensive technique in large
scale oil and gas pipe diagnosis system. This
technique apply strong magnetic fields to detect any
strange in the inner surface of the ...

(Universiti Malaysia Perlis, 2010-06-09)
In this study, spray pyrolysis method has been employed for the deposition of some transparent oxide thin films like ZnO, CdO and SnO2 onto glass substrate under atmospheric pressure using zinc acetate, cadmium acetate and ...
Analysis of particle size and XRD in ZnO-based varistor
(Universiti Malaysia Perlis, 2010-06-09)
ZnO varistors doped with Bi2O3, Sb2O3, CoO, MnO2 and Cr2O3 were prepared separately by
two mixing processes: conventional and masterbatching mixed-oxide process method.
After the mixing process, the ZnO-based varistor ...
