Sequences

451
Sequences are fundamental mathematical objects consisting of ordered lists of numbers that follow a specific rule or pattern. Sequences are critical in various mathematical concepts, including calculus, series, and number theory. They can model real-world phenomena such as population growth, financial investments, and physical processes like the diminishing height of a bouncing ball.Each number in a sequence is referred to as a term. Typically, the terms are denoted as a1, a2, a3,…, where...

Sequence Networks of Rotating Machines

A Y-connected synchronous generator, grounded through a neutral impedance, is designed to produce balanced internal phase voltages with only positive-sequence components. The generator's sequence networks include a source voltage that is exclusively in the positive-sequence network. The sequence components of line-to-ground voltages at the generator terminals illustrate this configuration.
Zero-sequence current induces a voltage drop across the generator's neutral impedance and other...

Maxam-Gilbert Sequencing

13.8K
In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.

Geometric Sequences01:30

Geometric Sequences

377
In systems where values diminish by a constant proportion at each stage, the resulting sequence follows a geometric structure. Each new value in the sequence is obtained by applying a fixed multiplier to the preceding term. This regular, proportional decline type is often used to represent processes involving gradual loss, such as energy dissipation or reduction in amplitude over time.When analyzing the total effect of such a process across unlimited iterations, the series of values is referred...

Arithmetic Sequences01:30

Arithmetic Sequences

320
An arithmetic sequence is a structured arrangement of numbers where each term is derived by adding a constant value, known as the common difference, to the previous term. This consistent pattern allows for the efficient computation of any term within the sequence as well as the cumulative sum of multiple terms. The formula for finding the nth term of an arithmetic sequence is:Here, aₙ represents the nth term of the sequence, a is the first term, d is the common difference, and n is the...

Basic Discrete Time Signals

861
The unit step sequence is defined as 1 for zero and positive values of the integer n. This sequence can be graphically displayed using a set of eight sample points, showing a step function starting from n=0 and remaining constant thereafter.
The unit impulse or sample sequence is mathematically expressed as zero for all n values except at n=0, where it is one. The unit impulse sequence, denoted by δ(n), is the first difference of the unit step sequence, while the unit step sequence u(n) is...

Area of Science:

  • * Dynamical Systems and Complex Systems Science
  • * Fractal Geometry and Symbolic Dynamics

Background:

  • * The study investigates symbolic sequences derived from arc-fractal systems, a novel class of fractals.
  • * These sequences, though simple in construction, exhibit non-trivial mathematical properties.

Purpose of the Study:

  • * To analyze the periodicity, complexity, and randomness of symbolic sequences from arc-fractals.

  • * Epsilon-machine (ϵ-machine) approach to quantify complexity and randomness.
  • * Analysis of fractal dimension, symmetry, and arc orientations.

Main Results:

  • * Symbolic sequences are demonstrated to be non-periodic despite simple generation rules.
  • * The ϵ-machine analysis confirms significant complexity and randomness, positioning them as neither periodic nor random.
  • * Complexity measures are comparable to the logistic map at the edge of chaos.

Conclusions:

  • * Arc-fractal symbolic sequences exhibit complex behavior, challenging initial assumptions based on simple rules.
  • * The findings link symbolic dynamics complexity to fractal geometry, offering a deeper understanding of these systems.
