estimating claims reserves using ibnr reserves

شرکت های بیمه در قبال بیمه گذاران متعهد می شوند که به ازای دریافت حق بیمه، خسارت وارده به بیمه گذاران را جبران نمایند. بنابراین بیمه گر همیشه مبالغی را بر عهده دارد که متعلق به بیمه گذاران است و مربوط به تعهدات آینده می باشد. این مبالغ را ذخایر فنی یا technical reserves گویند. بیمه گر موظف است در پایان سال مالی، هنگام بستن حساب ها، ذخایر فنی را محاسبه و نگهداری کند. پس از وقوع خسارت، بیمه گذار ...

estimating the deformation modulus of jointed rock mass under multilateral loading condition using analytical methods

rndetermination of rock mass deformation modulus is very important in different projects, especially in civil and mining engineering works. in-situ measurements such as dilatometer, plate load and flat jack methods may be applied to determine the deformation modulus. however, these methods are very expensive and time- consuming. analytical methods are very useful approaches which can also be us...

Bearing diagnostics using image processing methods

In complex machines, the failure signs of an early bearing damage are weak compared to other sources of excitations (e.g. gears, shafts, rotors, etc.). The task of emphasizing the failure signs is complicated by the fact that changes in operating conditions influence vibrations sources and change the frequency and amplitude characteristics of the signal, making it non-stationary. As a result, a...

Finite Mixture Model Diagnostics Using Resampling Methods

This paper illustrates the implementation of resampling methods in flexmix as well as the application of resampling methods for model diagnostics of fitted finite mixture models. Convenience functions to perform these methods are available in package flexmix. The use of the methods is illustrated with an artificial example and the seizure data set.
