Evaluation Of The Efficacy Of The Continuation Electroconvulsive Therapy In Treatment-Resistant Schizophrenia
(Univ Sao Paulo, Inst Psiquiatria, 2014)Background: Electroconvulsive therapy (ECT) has been reported being a safe and effective treatment in schizophrenia. However, there are a limited number of studies assessing continuation ECT utilization in patients with ... -
Forecasting Nonlinear Time Series With A Hybrid Methodology
(Pergamon-Elsevier Science Ltd, 2009)In recent years, artificial neural networks (ANNs) have been used for forecasting in time series in the literature. Although it is possible to model both linear and nonlinear structures in time series by using ANNs, they ... -
Forecasting Turkey Balance Of Trade With Box-Jenkins Models
(Bilgesel Yayincilik San & Tic Ltd, 2009)Foreign trade deficits are among the chronical problems of Turkey. Though export values have followed an increasing trend with the outward oriented development strategy adopted since 1980s, greater increase of import than ... -
Harm Perceptions Of Waterpipe Tobacco Smoking Among University Students In Five Eastern Mediterranean Region Countries: A Cross-Sectional Study
(2018)INTRODUCTION Waterpipe tobacco smoking (WTS) continues to be very common in the Eastern Mediterranean Region (EMR), partially because of cultural acceptance but also because of misconceptions of its harm. This paper aimed ... -
Hartley-Ross Type Unbiased Estimators Using The Stratified Random Sampling
(Hacettepe Univ, Fac Sci, 2017)This study mentions Hartley-Ross type unbiased ratio estimators of the finite population mean in the stratified random sampling using the auxiliary variable. We propose the unbiased estimators using the estimators in Kadilar ... -
Homogeneous Imputation Under Two Phase Probability Proportional To Size Sampling
(2019)In this paper, we consider the problem of missing complete at random (MCAR) values in two phase probability proportional to size (pps) sampling for the estimation of population mean. A class of estimators is considered by ... -
Hybrid Adaptive Evolutionary Algorithm Based On Decomposition
(Elsevier Science Bv, 2017)The performance of search operators varies across the different stages of the search/optimization process of evolutionary algorithms (EAs). In general, a single search operator may not do well in all these stages when ... -
Hybrid Constrained Evolutionary Algorithm For Numerical Optimization Problems
(2019)Constrained optimization are naturally arises in many real-life applications, and is therefore gaining a constantly growing attention of the researchers. Evolutionary algorithms are not directly applied on constrained ... -
Hybrid Non-Dominated Sorting Genetic Algorithm With Adaptive Operators Selection
(Elsevier Science Bv, 2017)Multiobjective optimization entails minimizing or maximizing multiple objective functions subject to a set of constraints. Many real world applications can be formulated as multi-objective optimization problems (MOPs), ... -
Improvement In Estimating The Population Mean In Simple Random Sampling
(Pergamon-Elsevier Science Ltd, 2006)This paper proposes some estimators for the population mean using the ratio estimators presented in [C. Kadilar, H. Cingi, Ratio estimators in simple random sampling, Applied Mathematics and Computation 151 (2004) 893-902] ... -
Improving Weighted Information Criterion By Using Optimization
(Elsevier Science Bv, 2010)Although artificial neural networks (ANN) have been widely used in forecasting time series, the determination of the best model is still a problem that has been studied a lot. Various approaches available in the literature ... -
Influenza Vaccination Prevalence Among The Elderly And Individuals With Chronic Disease, And Factors Affecting Vaccination Uptake
(2019)Objective: Our aim is to evaluate influenza vaccination rates among the elderly and individuals with underlying chronic disease, and factors that affect vaccination uptake. Methods: The study comprised individuals aged ... -
Is There a Relationship Between Vitamin D Status and Hypocalcemia-After Total Thyroidectomy?
(Editura Acad Romane, 2016)Context. Vitamin D plays a crucial role in calcium metabolism through parathormone-dependent process. Deficiency of this important nutrient may be associated with hypocalcemia after thyroidectomy. Objective. To evaluate ... -
Joint Prior Distributions for Variance Parameters in Bayesian Analysis of Normal Hierarchical Models
(Elsevier Inc, 2015)In random effect models, error variance (stage 1 variance) and scalar random effect variance components (stage 2 variances) are a priori modeled independently. Considering the intrinsic link between the stages 1 and 2 ...
