This article aims to incorporate the reliability model of power electronic converters into system analysis. The converter has widely been explored in device- and converter-levels according physics failure However, optimal decision-making for design, planning, operation, maintenance require system-level modeling electronic-based systems. Therefore, this proposes a procedure evaluate systems from...

We conducted two studies to explore the psychometric properties of the Positivity Scale (P Scale) among Chinese adults and early adolescents, using a sample of 552 adults (Study 1) and a sample of 888 early adolescents (i.e., middle school students) (Study 2). First, item analyses and factor analyses were conducted to investigate the one-factor structure of the P Scale. Second, internal consist...

a reliability analysis of suspension bridges against buffeting failure due to gustiness of wind velocity is carried out using the concept of pra (probabilistic risk analysis) procedure. for this purpose, the bending stresses at the critical nodes of the bridge deck are obtained for buffeting forces using a spectral analysis technique and a finite element approach. for the purpose of reliability...

With the development of restructured power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benef...

Average levels of interrater and intrarater reliability for job analysis data were investigated using meta-analysis. Forty-six studies and 299 estimates of reliability were cumulated. Data were categorized by specificity (generalized work activity or task data), source (incumbents, analysts, or technical experts), and descriptive scale (frequency, importance, difficulty, time-spent, and the Pos...
