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 ...
Fabrication of p-Type Nano-porous Silicon Prepared by Electrochemical Etching Technique in HF-Ethanol and HF-Ethanol-H2O Solutions
Nano-porous silicon were simply prepared from p-type single crystalline silicon wafer by electrochemical etching technique via exerting constant current density in two different HF-Ethanol and HF-Ethanol-H2O solutions. The mesoporous silicon layers were characterized by field emission scanning electron microscopy and scanning electron microscopy. The results demonstrate that the width of nano-p...

Electrochemical Reduction of Formic Acid on a Copper-Tin-Lead Cathode
The electrochemical reduction of formic acid in acidic solution (2 mol L HCl) on a Cu(88)Sn(6)Pb(6) cathode was studied. The main products of the reduction were methanol and ethanol having %Current Efficiencies (CEs) of 30.3 and 37.6% respectively at -0.8 V vs Ag/AgCl. Small amounts of methane and ethane were also detected. The rate of the reduction increased exponentially with the negative pot...
متن کاملChemical Composition of Nanoporous Layer Formed by Electrochemical Etching of p-Type GaAs
We have performed a detailed characterization study of electrochemically etched p-type GaAs in a hydrofluoric acid-based electrolyte. The samples were investigated and characterized through cathodoluminescence (CL), X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), and X-ray photoelectron spectroscopy (XPS). It was found that after electrochemical etching, the porous layer sh...
