Background Many dental problems such as tooth decay starts from childhood. In this regard, attitudes and beliefs of mothers about oral-dental health are important. The aim of this study was to determine the factors affecting oral-dental health in children of the mothers who referred to the Qom health centers by using of the Health Belief Model. Materials and Methods This is cross-sectional desc...

Abstract An extraordinary, if circumscribed, positive shift has occurred since the mid‐twentieth century in perceived status of Hugh Everett III's 1956 theory universal wave function quantum mechanics, now widely called Many‐Worlds Interpretation (MWI). Everett's starkly new interpretation denied existence a separate classical realm, contending that experimental data can be seen as presenting s...

One of the bottlenecks of current recognition (and graph matching) systems is their assumption of one-to-one feature (node) correspondence. This assumption breaks down in the generic object recognition task where, for example, a collection of features at one scale (in one image) may correspond to a single feature at a coarser scale (in the second image). Generic object recognition therefore req...

We propose a measure of the degree of ambiguity associated with a belief function and a nonparametric method to estimate it. The degree of ambiguity associated with a belief function is measured by the Kullback-Leibler diameter of the set of probability measures compatible with it. It is shown that an estimator based on the empirical version of the unambiguous measure generating the belief func...

Partially observable Markov decision process (POMDP) is a commonly adopted mathematical framework for solving planning problems in stochastic environments. However, computing the optimal policy of POMDP for large-scale problems is known to be intractable, where the high dimensionality of the underlying belief state space is one of the major causes. Our research focuses on studying two different...
