Network Function of a Circuit01:25

Network Function of a Circuit

236
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.

Propagation of Action Potentials01:25

Propagation of Action Potentials

4.7K
The propagation of an action potential refers to the process by which a nerve impulse, or "action potential," travels along a neuron.
Neurons (nerve cells) have a resting membrane potential, with a slightly negative charge inside compared to outside. This is maintained by ion channels, such as sodium (Na+) and potassium (K+) channels, which control the flow of ions. When a stimulus, like a touch or a signal from another neuron, triggers the neuron, sodium channels open, allowing sodium...

Line Protection with Impedance Relays

56
Coordinating time-delay overcurrent relays in complex radial systems and directional overcurrent relays in multi-source transmission loops can be challenging. Impedance relays address these issues by responding to the voltage-to-current ratio, specifically measuring the apparent impedance of a line. These relays become more sensitive during faults as current increases and voltage decreases, thereby reducing the apparent impedance.
Under normal conditions, low load currents keep the measured...

Ampere-Maxwell's Law: Problem-Solving

466
A parallel-plate capacitor with capacitance C, whose plates have area A and separation distance d, is connected to a resistor R and a battery of voltage V. The current starts to flow at t = 0. What is the displacement current between the capacitor plates at time t? From the properties of the capacitor, what is the corresponding real current?
To solve the problem, we can use the equations from the analysis of an RC circuit and Maxwell's version of Ampère's law.
For the first part of...

Maximum Power Transfer01:16

Maximum Power Transfer

180
Numerous practical applications within engineering disciplines, such as telecommunications, necessitate optimizing power delivery to a connected load. This pursuit, however, entails inherent internal losses, which can either equal or exceed the power supplied to the load. The Thevenin equivalent circuit is helpful in finding the maximum power a linear circuit can deliver to a load. It is assumed in this context that the load resistance can be adjusted.
By substituting the entire circuit with...

Area of Science:

  • Cybersecurity
  • Wireless Communication Networks
  • Internet of Things (IoT) Security

Background:

  • LoRaWAN (Long Range Wide Area Network) systems are susceptible to jamming attacks that disrupt end-node to gateway communication.
  • Existing research highlights the need to understand jamming attack feasibility and effectiveness against LoRaWAN.

Purpose of the Study:

  • To investigate the feasibility of implementing reactive jamming attacks on LoRaWAN using commercially available software-defined radio (SDR) equipment.
  • To evaluate the effectiveness of SDR-based reactive jammers in disrupting LoRaWAN communications by exploiting packet detection.

Main Methods:

  • Two experimental setups were designed: one using separate SDRs for reception and transmission, and another using a single SDR for both functions.
  • The experiments involved detecting LoRaWAN packet transmissions and initiating targeted interference to assess attack efficiency, reaction times, and packet loss.

Main Results:

  • Both experimental setups successfully jammed LoRaWAN packets across various spreading factors and payload sizes.
  • The reactive jamming approach demonstrated significant disruption capabilities, compromising message integrity.

Conclusions:

  • The study confirms the practical feasibility of sophisticated jamming attacks against LoRaWAN using accessible SDR technology.
  • There is an urgent requirement for developing and implementing robust security enhancements to protect LoRaWAN reliability against such threats.
