Background : Noise-induced hearing loss is among the most common cause of occupational-related hearing loss. Nowadays, noise-induced hearing loss is a disastrous event of industrial world that may influence all races, ethnics and age groups. Methods : This cross sectional study was performed on 100 workers exposed to noisy environment (greater 85db) in Azmayesh factory. Having excluded all con...
We prove linear convergence of gradient descent to a global minimum for the training deep residual networks with constant layer width and smooth activation function. further show that trained weights, as function index, admits scaling limit which is H\"older continuous depth network tends infinity. The proofs are based on non-asymptotic estimates loss norms weights along path. illustrate releva...
of the Ventumask and EasyVent, Ventukit, and EveCoulisse are very similar, respectively, whereas the Boussignac is the least expensive. However, based on the results of our study, the Boussignac device appears to perform more as a reservoir mask than as a CPAP device because of the low variable end-expiratory pressure, low airflow outputs, and high unadjustable FIO2. We concur with Drs Salturk ...
Abstract Introduction: The goal of the present research was to study the effect of transcranial magnetic stimulation of the brain over selective attention and continuous function of children suffering from specific learning disability disorder. Materials and Methods: The method of the present research was semi-experimental that was conducted by pre-test, post-test along with the control group. ...
Sparsity plays an important role in many fields of engineering. The cardinality penalty function, often used as a measure of sparsity, is neither continuous nor differentiable and therefore smooth optimization algorithms cannot be applied directly. In this paper we present a continuous yet non-differentiable sparsity function which constitutes a tight lower bound on the cardinality function. Th...
Optimum design of structures is achieved while the design variables are continuous and discrete. To reduce the computational work involved in the optimization process, all the functions that are expensive to evaluate, are approximated. To approximate these functions, a semi quadratic function is employed. Only the diagonal terms of the Hessian matrix are used and these elements are estimated fr...
For structural reliability assessment or risk analysis of aging offshore steel structures, it is essential to have a probabilistic model, which contains specific statistical parameters, and predicts long term corrosion loss as a function of time. The aim of this study is to propose such model for offshore jacket platforms in the Persian Gulf. Field measurements for material loss due to uniform ...
Female Sprague–Dawley rats were ovariectomized at 13 months of age. Four groups received different regimens of estrogen or estrogen plus progesterone replacement beginning either immediately, 3 months, or 10 months after ovariectomy and were compared with non-hormone-treated controls. Eight to twelve months after ovariectomy, animals were trained on a delayed matching-to-position (DMP) spatial ...
the improved estimator of the variance in the general linear model is presented under an asymmetric linex loss function.
