power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
In this paper, we propose a quasi-analytical device model of nanowire FET (NWFET) for both ballistic and drift-diffusion current transport, which can be used in any conventional circuit simulator like SPICE. The closed form expressions for I-V and C-V characteristics are obtained by analytically solving device equations with appropriate approximations. The developed model was further verified w...
introduction: direct observation of procedural skills (dops) is a way of evaluating procedural skills through observation in the workplace. the purpose of this study was to assess the role of dops in teaching and assessment of postgraduate students and to know the effect of repeated dops on improvement of the skills and confidence of the students. methods: this prospective study was conducted i...
Evaluation of pollutant transportation in soil is important from different environmental aspects such as soil and groundwater contamination. The purpose of this study is to measure 2, 4-D concentrations in a silty loam soil under two different treatments (normal and deficit irrigation) in a corn field and simulate the results using the PRZM-3 and LEACHP models. Total concentrations of 2, 4-D in...
