In the course of pursuing research on dinosaur growth rates (Myhrvold, 2013), I attempted to repli-cate the findings of Erickson et al. for Psittacosaurus lujiatunensis (Erickson et al., 2009a). In their study, they use femoral length measurements and age estimates for 80 specimens of P. lujiatunensis to estimate body mass and age, fit a growth curve, and construct a life table. These results w...

The electro-optic (EO) crystals used in the generation of tera-hertz radiation [Shan et al, 2000; Wen & Lindenberg, 2009; Shen et al., 2008] can be applied to non-invasive measurements of the electron bunch in the accelerator. The bunch length and arrival time of the electron bunch with respect to the laser can be measured with this technique. The electric field generated by the electron bunch ...

Spaceborne interferometric synthetic aperture radar (InSAR) operating at L-band and lower frequencies is susceptible to inhomogeneous ionosphere with spatial structures on scales comparable to targeted remote sensing features, i.e., from hundreds of kilometers to meters. The concerned ionospheric variations include medium-to-small scale electron density or total electron content (TEC) structure...

 Using the concept of system signature introduced by Samaniego (1985), Kochar et al. (1999) compared the lifetimes of the systems in which the lifetimes of the components are independent and identically distributed (i.i.d.) random variables. Their results are extended to the systems with exchangeable components by Navarro et al. (2005). This paper gives some alternative proofs to obtain th...

When using the K-nearest neighbours (KNN) method, one often ignores the uncertainty in the choice of K. To account for such uncertainty, Bayesian KNN (BKNN) has been proposed and studied (Holmes and Adams 2002 Cucala et al. 2009). We present some evidence to show that the pseudo-likelihood approach for BKNN, even after being corrected by Cucala et al. (2009), still significantly underest...

The purpose of this study is finding the sensitivity of central bank independence measurements on its impact on inflation in Iran. To this aim different measurements of the central bank independence were calculated using the indices of Grilli et al. (1991), Cukierman et al. (1992), Mathew (2006) and Dumiter (2009) for the period 1961-2012 . Although results of correlation between CBI index and ...
