Geometric Dilution of Precision (GDOP) is a coefficient for constellations of Global Positioning System (GPS) satellites. These satellites are organized geometrically. Traditionally, GPS GDOP computation is based on the inversion matrix with complicated measurement equations. A new strategy for calculation of GPS GDOP is construction of time series problem; it employs machine learning and artif...

Background: Continuing Medical Education (CME) of general practitioners (GPs) regarding most of the diseases, especially psychiatric disorders, is implementing worldwide to maintain and develop their knowledge, skills, and professional performance. We investigated the effects of CME on GPs knowledge in the field of psychiatric disorders in Dezful University of medical sciences (DUMS) as a Newly...

background & purpose: the purpose of this research was to evaluate the quantity and quality of continuing medical education programs from the viewpoint of general medical practitioners in ilam province. methods: the research method was descriptive survey and the statistic sample was a group of 61 general medical practitioners who have been working in ilam during 2010-2011 and were chosen by sim...

Deterioration models are important and essential part of any Pavement Management System (PMS). These models are used to predict future pavement situation based on existence condition, parameters causing deterioration and implications of various maintenance and rehabilitation policies on pavement. The majority of these models are based on roughness which is one of the most important indices in p...

One of the instruments for determination of position used in several applications is the Global Positioning System (GPS). With a cheap GPS receiver, we can easily find the approximate position of an object. Accuracy estimation depends on some parameters such as dilution of precision, atmospheric error, receiver noise, and multipath. In this study, position accuracy with GPS receiver is classifi...
