medication error (me) is the most common preventable cause of adverse drug events which negatively affects patient safety. inadequate, low-quality studies plus wide estimation variations in me from developing countries including iran, decreases the reliability of me evaluations. to clarify sources, underreporting reasons and preventive measures of mes, we reviewed iran current available literat...

in this paper, an iterative method is proposed for solving the matrix inverse problem $ax=b$ for hermitian-generalized hamiltonian matrices with a submatrix constraint. by this iterative method, for any initial matrix $a_0$, a solution $a^*$ can be obtained in finite iteration steps in the absence of roundoff errors, and the solution with least norm can be obtained by choosing a special kind of...

Many attitude estimation methods are based on an optimization problem posed in 1965 by Grace Wahba. All these methods will yield the same optimal estimate, except for inevitable computer roundoff errors. This note shows that Shuster’s Quaternion Estimator (QUEST) and Mortari’s Estimator of the Optimal Quaternion (ESOQ) are essentially identical even in the presence of computer roundoff errors. ...

In recent years, digitization of cultural heritage objects, for the purpose creating virtual museums, is becoming increasingly popular. Moreover, institutions use modern methods to create three-dimensional (3D) models objects historical significance form digital libraries and archives. This research aims suggest a method protecting these 3D from abuse while making them available on Internet. Th...

Generalized structured component analysis (GSCA) is a component-based approach to structural equation modeling (SEM), where latent variables are approximated by weighted composites of indicators. It has no formal mechanism to incorporate errors in indicators, which in turn renders components prone to the errors as well. We propose to extend GSCA to account for errors in indicators explicitly. T...

BACKGROUND Relatively little is known about prescribing errors in general practice, or the factors associated with error. AIM To determine the prevalence and nature of prescribing and monitoring errors in general practices in England. DESIGN AND SETTING Retrospective case-note review of unique medication items prescribed over a 12-month period to a 2% random sample of patients. Fifteen gene...
