there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...

Introduction: Obesity and hypertension are community health problems. The objective of this study was to diagnose obesity and hypertension in Isfahani students by artificial neural network. Method: The present study was a diagnostic and predictive one that used the information of 460 students aged 7-18 years old in Isfahan to design a neural network with 11 input variables (age, sex, weight, he...
Introduction: Genetics counseling has an important role in preventing genetics abnormalities. These abnormalities have economical, social, psychological and emotional stresses on families and on community. Therefore, it is necessary to have careful programs to increase the knowledge of people about the importance of genetics counseling. In this study, the necessary cases of pre-marriage c...

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...
spherical equivalent (se) has not been linked to increased cardiovascular morbidity. methods: 132 hungarian twins (age 43.3±16.9 years) underwent refraction measurements (huvitz mrk-3100 premium autorefractokeratometer) and oscillometry (tensiomed arteriograph). results: heritability analysis indicated major role for genetic components in the presence of right and left se (82.7%, 95%ci, 62.9 to...
introduction: pathophysiology of cancer is based on genetic instabilities. this can explain recent important role of genetic studies in such diseases. defects can be large (on molecular scale) at the level of chromosomal or small in nucleotide level, which eventually causes to irreversible change in the cell. conventional technical methods in cancer genetics are generally based on molecular or ...
background: essential hypertension tends to a familial mode. its pattern of inheritance is heterogeneous, but the frequencies of different mode of inheritance vary in different populations. determining of the mode of inheritance in each family is the basic information that is needed for the risk estimation in those family members. determination of pattern of inheritance in families with at leas...
Generative models have shown breakthroughs in a wide spectrum of domains due to recent advancements machine learning algorithms and increased computational power. Despite these impressive achievements, the ability generative create realistic synthetic data is still under-exploited genetics absent from population genetics. Yet known limitation field reduced access many genetic databases concerns...
