Reliability evaluation of a large-scale composite power system faces to numerous events/outage and consequently imposes an extensive burden of calculations. In order to simplify the problem, determination of an equivalent system for large-scale power system is inevitable. This paper proposes a framework as reduction technique to separate a composite power system to three areas: external area, o...
Using a tight-binding model and a tranfer-matrix technique, we numerically investigate the effects of the coupling strength, and the length of the molecule on the electronic transmission through a CNT/(single) molecule/CNT system. With trans-polyacetylene (trans-PA) as the molecule sandwiched between two semi-infinite carbon nanotube(CNT), we rely on Landauer formalism as the basis for studyi...
The present research discusses four ‘physical’ models of system and calculates the reliability function during system’s aging and maturity on the basis of the system structure.
INTRODUCTION Insufficient skills in drug dose calculations increase the risk for medication errors. Even experienced nurses may struggle with such calculations. Learning flexibility and cost considerations make e-learning interesting as an alternative to classroom teaching. This study compared the learning outcome and risk of error after a course in drug dose calculations for nurses with the tw...
Background: High-energy linear accelerator (linac) is a valuable tool and the most commonly device for external beam radiation treatments in cancer patients. In the linac head, high-energy photons with energies above the threshold of interaction produce photoneutrons. These photoneutrons deliver the extra dose to the patients in the planning treatment and increase the risk of secondary cancer.O...
In this paper, some of the electronic and structural properties of UY2(Y=Ga,Ge) compounds are investigated. The calculations was conducted using the pseudopotential method based on the density functional theory with PWscf code.. The exchange function is a correlation between GGA.PBE and LDA. The increase in pressure also leads to positive changes in the enthalpy of the system, which indicates t...
The initial establishment of a Wireless system is very expensive and time consuming process. Due to this it is require to develop a mathematical model before establishment of such type of systems. The Calculation of path loss, link budgets etc are in the part of wireless system designing. Radio propagation is profoundly site specific and varies considerably depending on topography, frequency of...
BACKGROUND Identifying people at risk of developing diabetic foot complications is a vital step in prevention programs in primary healthcare settings. Diabetic foot risk stratification systems predict foot ulceration. The aim of this study was to explore the views and experiences of potential end users during development and formative evaluations of an electronic diabetic foot risk stratificati...
