Efficiency Measurement of Clinical Units Using Integrated Independent Component Analysis-DEA Model under Fuzzy Conditions

Background and Objectives: Evaluating the performance of clinical units is critical for effective management of health settings. Certain assessment of clinical variables for performance analysis is not always possible, calling for use of uncertainty theory. This study aimed to develop and evaluate an integrated independent component analysis-fuzzy-data envelopment analysis approach to accurate ...

Calculation of airkerma conversion factor to personal dose equivalent at various depths using the Monte Carlo Code GATE

Several studies have been done with the aim of improving the quality of the radiation protection measurement in radiology and nuclear medicine. Among  different subjects which are capable to be considered in this area, the measurement of the operational quantities of protection against the radiation ,such as, personal dose equivalent ,HP(d), at different depths (d=0.07mm, 3mm, 10mm) is an impor...

Eciency Measurement of Multiple Components units in Data Envelopment Analysis Using Common Set of Weights

Optimal Placement of Phasor Measurement Units in Khorasan Network Using a Hybrid Intelligent Technique

In this paper, an efficient and comprehensive hybrid intelligent technique for the optimal placement of phasor measurement units (PMUs) is proposed to minimize the number of PMU installation subjected to full network observability. Three main purposes of PMUs output synchronous measurements are monitoring, control, and protection of power system. We have combined Binary Imperialistic Competitio...

Presenting a New Method Based on Branch Placement for Optimal Placement of Phasor Measurement Units

In this paper, a new method based on branch placement for the optimal positioning of Phasor Measurement Units (PMUs) in power systems is proposed. In this method, the PMUs are in type of single-channel and are installed at the beginning of the branches. Therefore, they are able to measure the bus voltages. Also, the installation of the PMUs on the branches increases the security of observabilit...
