Transport Number01:31

Transport Number

45
The transport number is the fraction of the total current carried by an ion in an electrolyte solution. It is defined as the ratio of the current carried by a specific ion to the total current flowing through the solution. The transport number, t, is central to understanding ionic mobility, which describes how fast an ion moves under the influence of an electric field. This link connects the physical behavior of ions in solution to the chemical processes that occur during electrochemical...

Persuasion Strategies01:52

Persuasion Strategies

43.8K
Researchers have tested many persuasion strategies, including the foot-in-the door and the door-in-the-face techniques, in a variety of contexts. Ultimately, the principles are effective in selling products and changing people’s attitude, ideas, and behaviors (Cialdini & Goldstein, 2004).

Load-frequency control01:28

Load-frequency control

714
Load-frequency control (LFC) is vital for maintaining power system stability, ensuring that frequency and power flows remain within acceptable limits during load changes. Turbine-governor control eliminates rotor accelerations and decelerations following load changes. However, a steady-state frequency error persists when the change in the turbine-governor reference setting is zero. In an interconnected power system, each area agrees to export or import a scheduled amount of power through...

Introduction to Functions01:29

Introduction to Functions

382
Functions are essential mathematical tools used to describe consistent relationships between varying quantities. A function connects each input to a single, corresponding output based on a defined rule. These relationships appear in both everyday contexts and natural phenomena, providing a framework for understanding change and prediction.One common real-life example is a parking garage fee system, where the total cost depends on the amount of time a vehicle remains inside. In this case, the...

Probability Histograms01:17

Probability Histograms

13.4K
A probability histogram is a visual representation of a probability distribution. Similar a typical histogram, the probability histogram consists of contiguous (adjoining) boxes. It has both a horizontal axis and a vertical axis. The horizontal axis is labeled with what the data represents. The vertical axis is labeled with probability. Each rectangular bar in the histogram is 1 unit wide, which suggests that the area under each bar equals the probability, P(x), where x is 1, 2, 3, and so on.

Social Traps01:41

Social Traps

27.0K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Area of Science:

  • Airport Operations Management
  • Transportation Engineering
  • Operations Research

Background:

  • Aircraft surface congestion during peak hours leads to significant delays and increased operational costs.
  • Current aircraft pushback management strategies often fail to adequately address congestion pricing and operational quality.
  • Optimizing aircraft pushback is crucial for efficient airport throughput and minimizing external costs.

Purpose of the Study:

  • To develop an aircraft pushback slot allocation model incorporating congestion pricing and surface operation quality.
  • To propose a quantitative method for assessing the external cost of surface congestion.
  • To minimize the total surface cost associated with aircraft pushback operations.

Main Methods:

  • Introduction of the "external cost of surface congestion" concept and its quantitative analysis.
  • Development of an aircraft pushback slot allocation model aimed at minimizing total surface cost.
  • Design of an improved discrete differential evolution algorithm for optimization.
  • Simulation and comparative analysis of the proposed strategy against other methods at Xinzheng International Airport.

Main Results:

  • The proposed congestion pricing strategy significantly reduces aircraft delays and optimizes delay distribution.
  • The model effectively manages aircraft pushback during rush hour, outperforming alternative strategies.
  • The implemented approach does not lead to substantial increases in overall surface costs.
  • The developed algorithm demonstrates effectiveness in optimizing slot allocation.

Conclusions:

  • The proposed aircraft pushback slot allocation model and algorithm are effective for managing peak-hour airport operations.
  • Congestion pricing offers a viable solution for reducing delays and improving surface efficiency.
  • The model provides a practical tool for airport authorities to enhance operational management and reduce external costs.
