Stability of structures01:14

Stability of structures

212
In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...

Woodward–Hoffmann Selection Rules and Microscopic Reversibility

3.2K
Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...

BIBO stability of continuous and discrete -time systems

473
System stability is a fundamental concept in signal processing, often assessed using convolution. For a system to be considered bounded-input bounded-output (BIBO) stable, any bounded input signal must produce a bounded output signal. A bounded input signal is one where the modulus does not exceed a certain constant at any point in time.
To determine the BIBO stability, the convolution integral is utilized when a bounded continuous-time input is applied to a Linear Time-Invariant (LTI) system....

Propagation of Uncertainty from Random Error00:59

Propagation of Uncertainty from Random Error

752
An experiment often consists of more than a single step. In this case, measurements at each step give rise to uncertainty. Because the measurements occur in successive steps, the uncertainty in one step necessarily contributes to that in the subsequent step. As we perform statistical analysis on these types of experiments, we must learn to account for the propagation of uncertainty from one step to the next. The propagation of uncertainty depends on the type of arithmetic operation performed on...

Sequence Networks of Rotating Machines

129
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...

Random Error01:04

Random Error

1.2K
Random or indeterminate errors originate from various uncontrollable variables, such as variations in environmental conditions, instrument imperfections, or the inherent variability of the phenomena being measured. Usually, these errors cannot be predicted, estimated, or characterized because their direction and magnitude often vary in magnitude and direction even during consecutive measurements. As a result, they are difficult to eliminate. However, the aggregate effect of these errors can be...

Area of Science:

  • Complex Systems Science
  • Network Theory
  • Dynamical Systems

Background:

  • Most complex system models assume homogeneity, where all elements share identical properties.
  • Natural systems often exhibit heterogeneity, with some elements possessing distinct characteristics.
  • Criticality in homogeneous systems is typically confined to a narrow parameter range near phase transitions.

Purpose of the Study:

  • To investigate the impact of heterogeneity on criticality and antifragility in complex systems.
  • To determine if heterogeneity can broaden the parameter space for these phenomena.
  • To explore the relationship between homogeneity and heterogeneity in system dynamics.

Main Methods:

  • Utilized random Boolean networks as a general model for discrete dynamical systems.
  • Introduced heterogeneity in temporal, structural, and functional aspects of the networks.
  • Analyzed the parameter space to identify regions of criticality and antifragility.

Main Results:

  • Heterogeneity additively broadens the parameter region where criticality is observed.
  • Increased heterogeneity also expands the parameter regions associated with antifragility.
  • Maximum antifragility, however, was found in specific homogeneous network parameter settings.

Conclusions:

  • Heterogeneity plays a significant role in expanding the operational range of criticality and antifragility in complex systems.
  • The ideal balance between homogeneity and heterogeneity is not fixed but is nuanced, context-specific, and potentially dynamic.
  • Findings suggest that natural systems' heterogeneity is crucial for their resilience and adaptability.
