Ph.D. Dissertation
Title: Bayesian Inference on the Reliability of the
Stress–Strength Model
Supervisor: Prof. Masoud Ganji
Advisor: Dr. Behdad Mostafaei
Description: This dissertation focuses on the point and
interval estimation of stress–strength reliability
P(X>Y) using a Bayesian approach. The proposed methods were applied to several real-world problems in medicine and engineering.
M.Sc. Thesis
Title: A Method of Signal Detection for Random Fields Using
Reproducing Kernel Hilbert Space (RKHS)
Supervisor: Prof. Khalil Shafiei
Advisor: Dr. Alireza Taheriyoun
Description: This thesis considers the problem of signal
detection for scale–space random fields and constructs a test statistic for
testing the null hypothesis of no signal versus the presence of a signal using
Reproducing Kernel Hilbert Space (RKHS) methods. The covariance function of
this random field was obtained and the corresponding RKHS constructed. Finally,
the generalized likelihood ratio was derived, and it was shown that the global
maximum of the image is a sufficient statistic for this test.
