Network Function of a Circuit01:25

Network Function of a Circuit

339
Frequency response analysis in electrical circuits provides vital insights into a circuit's behavior as the frequency of the input signal changes. The transfer function, a mathematical tool, is instrumental in understanding this behavior. It defines the relationship between phasor output and input and comes in four types: voltage gain, current gain, transfer impedance, and transfer admittance. The critical components of the transfer function are the poles and zeros.

Aggregates Classification01:29

Aggregates Classification

357
Aggregate classification is generally based on its size, petrographic characteristics, weight, and source. Size classification ranges from coarse to fine aggregates, defined by the size of the particles. Coarse aggregates are particles that do not pass through ASTM sieve No. 4, and aggregates that pass through the sieve are fine aggregates.
Petrographic classification groups aggregates based on common mineralogical characteristics. Some of the common mineral groups found in aggregates are...

Pilot and Numeric Relaying01:21

Pilot and Numeric Relaying

120
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

Types of Aggregate Grading01:15

Types of Aggregate Grading

668
Aggregate grading is crucial in economically obtaining a concrete mix with adequate strength, reasonable workability, and minimal segregation. There are four types of aggregate gradation: well-graded, uniformly (or one-sized) graded, gap-graded, and open-graded.
Well-graded aggregates include a complete range of necessary size fractions that fit together to create a dense matrix with minimal voids, represented by a smooth, continuous gradation curve. This type of grading ensures good...

Maximum Size of Aggregate01:12

Maximum Size of Aggregate

181
The maximum size of aggregate is defined as the aperture of the sieve retaining 15 percent or more of the particles present in the aggregate sample. The aggregate's maximum size impacts the concrete's water requirement, workability, and strength. Larger aggregates reduce the surface area needing cement paste coverage, which can lower water needs, thereby allowing a decrease in the water-to-cement ratio when the desired workability and richness of the mix are to be maintained, which can...

Area of Science:

  • Network Engineering
  • Distributed Systems
  • Cloud Computing

Background:

  • Air-ground integrated networks face challenges with service function chaining (SFC) deployment, leading to network load imbalance.

Main Methods:

  • Developed a model for VNF aggregation based on task similarity, classifying tasks and selecting VNFs within classes under resource constraints.
  • Implemented load balancing by adjusting the similarity threshold.
  • Utilized a network resource-aware SFC mapping scheme for optimal physical node selection.

Main Results:

  • The proposed scheme demonstrated superior performance in load balancing compared to existing VNF aggregation methods.
  • Simulation results confirmed the scheme's effectiveness and resource-consumption efficiency.
  • Achieved better network security and reliability through improved load distribution.

Conclusions:

  • The task-similarity-based VNF aggregation scheme effectively addresses load imbalance in air-ground integrated networks.
  • The approach enhances SFC deployment by considering resource consumption and load balancing prior to mapping.
  • This method offers a resource-efficient and effective solution for VNF aggregation.
