modeling loss data by phase-type distribution
بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
Point Defects in B2 Intermetallic Compounds
We are applying perturbed angular correlations (PAC) to study point defects near 111In probes in ordered B2 alloys. Systems studied include NiAl, CoAl, FeAl, CoGa and PdIn Ten different point defect configurations have been observed in annealed, quenched or mechanically-milled samples. The present status of this work is summarized. Systematics of hyperfine interactions of vacancy defects are th...
متن کاملIntermetallic REPtZn Compounds with TiNiSi-type Structure
The equiatomic rare earth compounds REPtZn (RE = Y, Pr, Nd, Gd–Tm) were synthesized from the elements in sealed tantalum tubes by high-frequency melting at 1500 K followed by annealing at 1120 K and quenching. The samples were characterized by powder X-ray diffraction. The structures of four crystals were refined from single-crystal diffractometer data: TiNiSi type, Pnma, a = 707.1(1), b = 430....
متن کاملX-ray absorption spectra and electronic structure of Haucke-phase-type intermetallic compounds
— The K X-ray absorption discontinuity of cobalt in the compounds of the RCo5 family (R = rare earth or yttrium) has been measured with a bent crystal spectrograph. It is observed that the main discontinuity shifts to the low energy side, with respect to that in pure cobalt indicating a flow of charge from R to Co. The plot between the observed shifts and the number of covalently bonded electro...

Z. Naturforsch. 55 b, 155-161 (2000); received November 10, 1999 Intermetallic Cerium Compounds, Crystal Structure New intermetallic cerium compounds Ce2 7iMg (T = Ni, Cu, Pd), CqiTjCd (T Pd, Pt, Au), and CtiTzPb (T = Pt, Au) were prepared by reaction of the elements in sealed tantalum tubes in a high-frequency furnace. Most C e :^ ^ (X = Mg, Cd, Pb) compounds are stable after annealing at abou...
