this thesis is a study on insurance fraud in iran automobile insurance industry and explores the usage of expert linkage between un-supervised clustering and analytical hierarchy process(ahp), and renders the findings from applying these algorithms for automobile insurance claim fraud detection. the expert linkage determination objective function plan provides us with a way to determine whi...
due to extraordinary large amount of information and daily sharp increasing claimant for ui benefits and because of serious constraint of financial barriers, the importance of handling fraud detection in order to discover, control and predict fraudulent claims is inevitable. we use the most appropriate data mining methodology, methods, techniques and tools to extract knowledge or insights from ...
We consider a generalization of the classical quadratic assignment problem, where coordinates of locations are uncertain and only upper and lower bounds are known for each coordinate. We develop a mixed integer linear programming model as a robust counterpart of the proposed uncertain model. A key challenge is that, since the uncertain model involves nonlinear objective function of the ...
in this review, we discuss the use of a variety of 3-d models (particularly 3-d skin, lung, breast and endothelial) in radiobiological research and highlight the differences in responses compared to 2-d culturing conditions (monolayers). we review the characteristics of existing 3-d models and aim to point out the substantial advantages 3-d cultures provide for modern radiobiology. in particula...
The thermodynamical property of a small cluster including M Hubbard dimers, each of which is described by the two-site Hubbard model, has been discussed within the nonex-tensive statistics (NES). The temperature dependence of the energy, entropy, specific heat and susceptibility has been calculated for M = 1, 2, 3 and ∞ (corresponding to q = 1) with the use of the relation between the entropic ...
In this study, the effect of four-spin exchanges between the nearest and next nearest neighbor spins of honeycomb lattice on the phase diagram of S=3/2 antiferomagnetic Heisenberg model is considered with two-spin exchanges between the nearest and next nearest neighbor spins. Firstly, the method is investigated with classical phase diagram. In classical phase diagram, in addition to Neel order,...
background: the best management for an ovarian mass is provided by appropriate prediction of malignancy. the aim of our study is to construct and validate a new malignancy probability score based on four simple sonographic findings and age. methods: in a cross sectional study; histopathological files of 3303 ovarian mass patients and tertiary hospitals, have reviewed within 6 years (2000-2006)....
empirical studies show that there is stronger dependency between large losses than large profit in financial market, which undermine the performance of using symmetric distribution for modeling these asymmetric. that is why the assuming normal joint distribution of returns is not suitable because of considering the linier dependence, and can be lead to inappropriate estimate of var. copula theo...
the present study aim is to offer a systematic method of assessing the credit risk of banks and also to identify key indicators using decision making trial and evaluation laboratory (dematel) technique as well as using logit regression in order to predict the credit risk of listed banks. the population of the study consists of the legal clients of the bank (ansar bank, bank saderat iran, bank m...
background & objectives:airq software proved to be a valid and reliable tool to estimate the potential short term effects of air pollution. in this study the airq2.2.3 model was used to evaluate adverse health effects caused by nitrogen dioxide(no2) exposure in ahvaz during 2009. materials & methods:the airq,developed by the world health organization (who) to predict health endpoints a...
