in this paper, we have proposed a new iterative method for finding the solution of ordinary differential equations of the first order. in this method we have extended the idea of variational iteration method by changing the general lagrange multiplier which is defined in the context of the variational iteration method.this causes the convergent rate of the method increased compared with the var...

UNLABELLED Among other lifestyle problems, sleeping problems have been related to alcohol use. AIM The aim of this study was to evaluate complaints about sleep in trauma patients in an emergency department and its relation to alcohol use disorders (AUD). METHOD In an emergency department, trauma patients (1014 females, 1680 males) were screened using a computerized questionnaire addressing ...

We propose and study a block-iterative projections method for solving linear equations and/or inequalities. The method allows diagonal component-wise relaxation in conjunction with orthogonal projections onto the individual hyperplanes of the system, and is thus called diagonally-relaxed orthogonal projections (DROP). Diagonal relaxation has proven useful in accelerating the initial convergence...

In this paper, seventh-order iterative methods for the solution ofnonlinear equations are presented. The new iterative methods are developed byusing weight function method and using an approximation for the last derivative,which reduces the required number of functional evaluations per step. Severalexamples are given to illustrate the eciency and the performance of the newiterative methods.

The fundamental idea behind all multigrid methods is to compute using diierent scales in order to obliterate error components of diierent scales. Error components can be thought of as waves. A long wave, which has low frequency, on one grid is a short wave, or high frequency, on a coarse enough related grid. A number of iterative methods (e.g., relaxation and alternating direction implicit meth...

OBJECTIVE To evaluate the association between the risk of ectopic pregnancy (EP) and the use of common contraceptives during the previous and current conception/menstrual cycle. METHODS A multi-center case-control study was conducted in Shanghai. Women diagnosed with EP were recruited as the case group (n = 2,411). Women with intrauterine pregnancy (IUP) (n = 2,416) and non-pregnant women (n ...

BACKGROUND There is no adequate health service or counseling specifically suitable for adolescents in Ethiopia. Adolescents' satisfaction on the health service provided is important to increase utilization and quality of care. The objective of this study was to assess health service utilization, reported satisfaction and predictors of satisfaction among adolescents of 15-19 years in Dejen Distr...

BACKGROUND Alcohol and other drugs use is a problem among adolescents leading to numerous physical, social, and educational damages. OBJECTIVE For determining the prevalence of alcohol and other substance use as well as the factors associated with the experience of alcohol use in adolescents. PATIENTS AND METHODS This is a population-based and cross-sectional study, which was conducted in A...

Electricity price predictions have become a major discussion on competitive market under deregulated power system. But, the exclusive characteristics of electricity price such as non-linearity, non-stationary and time-varying volatility structure present several challenges for this task. In this paper, a new forecast strategy based on the iterative neural network is proposed for Day-ahead price...
