Distribution Reliability and Automation01:25

Distribution Reliability and Automation

134
Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

Mechanistic Models: Compartment Models in Algorithms for Numerical Problem Solving

81
Mechanistic models play a crucial role in algorithms for numerical problem-solving, particularly in nonlinear mixed effects modeling (NMEM). These models aim to minimize specific objective functions by evaluating various parameter estimates, leading to the development of systematic algorithms. In some cases, linearization techniques approximate the model using linear equations.
In individual population analyses, different algorithms are employed, such as Cauchy's method, which uses a...

Simplified Synchronous Machine Model

285
The Synchronous Machine Model is a fundamental tool in analyzing and ensuring the transient stability of power systems. This model simplifies the representation of a synchronous machine under balanced three-phase positive-sequence conditions, assuming constant excitation and ignoring losses and saturation. The model is pivotal for understanding the behavior of synchronous generators connected to a power grid, particularly during transient events.
In this model, each generator is connected to a...

Multimachine Stability01:25

Multimachine Stability

197
Multimachine stability analysis is crucial for understanding the dynamics and stability of power systems with multiple synchronous machines. The objective is to solve the swing equations for a network of M machines connected to an N-bus power system.
In analyzing the system, the nodal equations represent the relationship between bus voltages, machine voltages, and machine currents. The nodal equation is given by:

Stereotype Content Model02:16

Stereotype Content Model

14.8K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Summary
This summary is machine-generated.

Automatic digital (AD) analysis of intraoral scans is more reproducible and faster than manual digital (MD) analysis. However, significant measurement differences exist, meaning AD and MD methods should not be interchanged.

Area of Science:

  • Dental diagnostics
  • Digital dentistry
  • Orthodontic analysis

Background:

  • Intraoral scanners are increasingly used in orthodontics.
  • Digital models offer potential advantages over traditional methods.
  • Evaluating the efficiency and accuracy of digital analysis is crucial.

Purpose of the Study:

  • To compare the reliability, reproducibility, and time efficiency of automatic digital (AD) versus manual digital (MD) analysis of intraoral scan models.
  • To assess differences in key orthodontic measurements between the two methods.

Main Methods:

  • Two examiners analyzed 26 intraoral scanner records using both MD and AD methods.
  • Bland-Altman plots assessed tooth size reproducibility.
  • Wilcoxon signed-rank test compared model analysis parameters and time.

Main Results:

  • Automatic digital analysis showed smaller measurement deviations (0.08 mm vs. 0.15 mm).
  • AD analysis was significantly faster (0.56 min vs. 8.62 min).
  • Significant differences in 12-tooth and arch perimeter measurements were found between AD and MD methods (P < 0.001).

Conclusions:

  • Automatic digital analysis offers superior reproducibility and time efficiency.
  • Clinically significant differences in measurements necessitate distinct application of AD and MD methods.
  • AD and MD analyses are not interchangeable for orthodontic modeling.
