Elastic Collisions: Case Study01:15

Elastic Collisions: Case Study

21.0K
Elastic collision of a system demands conservation of both momentum and kinetic energy. To solve problems involving one-dimensional elastic collisions between two objects, the equations for conservation of momentum and conservation of internal kinetic energy can be used. For the two objects, the sum of momentum before the collision equals the total momentum after the collision. An elastic collision conserves internal kinetic energy, and so the sum of kinetic energies before the collision equals...

Propagation of Uncertainty from Systematic Error01:10

Propagation of Uncertainty from Systematic Error

1.6K
The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this...

Elastic Collisions: Introduction

15.4K
An elastic collision is one that conserves both internal kinetic energy and momentum. Internal kinetic energy is the sum of the kinetic energies of the objects in a system. Truly elastic collisions can only be achieved with subatomic particles, such as electrons striking nuclei. Macroscopic collisions can be very nearly, but not quite, elastic, as some kinetic energy is always converted into other forms of energy such as heat transfer due to friction and sound. An example of a nearly...

Propagation of Uncertainty from Random Error

2.1K
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...

Actor-Observer Effect01:23

Actor-Observer Effect

484
The actor-observer effect, a cognitive bias closely linked to the fundamental attribution error, refers to the tendency for individuals to attribute their behavior to external, situational factors while explaining others’ behavior in terms of internal, dispositional traits. This asymmetry in attribution significantly influences social perception and judgment.Cognitive Mechanisms Behind the EffectTwo primary psychological mechanisms contribute to the actor-observer effect: differences in...

Collisions in Multiple Dimensions: Problem Solving

5.6K
In multiple dimensions, the conservation of momentum applies in each direction independently. Hence, to solve collisions in multiple dimensions, we should write down the momentum conservation in each direction separately. To help understand collisions in multiple dimensions, consider an example.
A small car of mass 1,200 kg traveling east at 60 km/h collides at an intersection with a truck of mass 3,000 kg traveling due north at 40 km/h. The two vehicles are locked together. What is the...

    Area of Science:

    • Control Systems Engineering
    • Networked Systems
    • Cybersecurity

    Background:

    • Multiagent systems (MAS) face challenges like sensor loss and cyber-attacks, hindering consensus.
    • Event-triggering mechanisms reduce communication load but require careful design in MAS.

    Purpose of the Study:

    • To investigate observer-based event-triggering consensus control for discrete-time MAS.
    • To address challenges posed by lossy sensors and probabilistic cyber-attacks.
    • To develop a controller design independent of the number of agents.

    Main Methods:

    • A novel distributed observer estimates relative states for feedback control.
    • An event-triggered mechanism with a state-independent threshold minimizes data transmission.
    • Analysis utilizes eigenvalues/eigenvectors of the Laplacian matrix.
    • Controller gains are derived from matrix inequalities.

    Main Results:

    • A sufficient condition for achieving consensus in the closed-loop MAS is derived.
    • The controller gain is independent of the number of agents.
    • An algorithm optimizes the consensus bound.
    • Simulations validate the proposed control scheme.

    Conclusions:

    • The proposed observer-based event-triggering control effectively achieves consensus in discrete-time MAS.
    • The method robustly handles sensor loss and cyber-attacks.
    • The design offers efficient communication and scalability.
