INCREASING THE EFFICIENCY OF ELECTROCHEMICAL PROTECTION

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

An Electrochemical Measurement for Evaluating the Cathodic Disbondment of Buried Pipeline Coatings under Cathodic Protection

Steel pipelines are susceptible to corrosion by the action of corrosive substance in the environment and one of the most common failure modes in buried pipeline coatingis cathodic disbondment. Consequently, Electrochemical Impedance Spectroscopy (EIS) was used to assess the effect of three important parameters, the thickness of coating, the artificial defect ...

The Effect of efficiency of cooperative learning method on increasing blind students' perception of mathematical conceptions

Blind students have limitations that their teachers have to apply efficient educational methods for them. Since mathematics concepts are abstract for blind students and they cannot understand these concepts deeply, this research has tried that used and introduced cooperative learning method for this reason. Blind students have high listening capacity then cooperative learning method can pro...

Evaluating the Efficiency of Shortcut Span Protection

This paper presents a comparison of various recovery methods in terms of capacity efficiency with the underlying aim of reducing control plane load. In particular, a method where recovery requests are bundled towards the destination (Shortcut Span Protection) is evaluated can compared against traditional recovery methods. The optimization model is presented and our simulation results show that ...
