Stream Function01:20

Stream Function

1.9K
In two-dimensional incompressible fluid flow, the continuity equation is essential for ensuring mass conservation, meaning that any change in fluid entering or exiting a region is balanced by a corresponding change elsewhere. For incompressible flow, where density remains constant, this requirement simplifies to the condition that the divergence of the velocity field must be zero. Mathematically, this is expressed as,

Signal and System01:26

Signal and System

1.5K
A signal x(t) is a set of data or a time function representing a variable of interest. Signals typically convey information about a phenomenon, such as atmospheric temperature, humidity, human voice, television images, a dog's bark, or birdsongs. More generally, a signal can be a function of more than one independent variable. For instance, images depend on horizontal and vertical positions and can be regarded as two-dimensional signals. However, this text will focus on one-dimensional...

Rapidly Varying Flow01:24

Rapidly Varying Flow

325
Rapidly varying flow (RVF) in open channels is characterized by abrupt changes in flow depth over a short distance, with the rate of depth change relative to distance often approaching unity. These flows are inherently complex due to their transient and multi-dimensional nature, making exact analysis difficult. However, approximate solutions using simplified models provide valuable insights into their behavior.Key Features of Rapidly Varying FlowRVF is commonly observed in scenarios involving...

Reducing Line Loss01:18

Reducing Line Loss

292
In a three-phase circuit, line loss is an indicator of energy dissipated as heat due to the resistance of transmission lines. To address this, incorporating transformers into the system—a step-up transformer at the source and a step-down transformer at the load—is a strategic solution. Two three-phase transformers are introduced to improve this.
With a step-up transformer at the source, the voltage is increased, thereby reducing the current in the transmission lines since power loss in...

Uniform Depth Channel Flow01:27

Uniform Depth Channel Flow

441
Uniform depth channel flow keeps fluid depth consistent along channels such as irrigation canals. In natural channels, such as rivers, approximate uniform flow is often assumed. This condition occurs when the channel’s bottom slope matches the energy slope, balancing potential energy lost from gravity with head loss due to shear stress. This balance prevents depth changes along the channel length, resulting in a steady, uniform flow.Uniform flow in open channels with a constant cross-section...

Linear time-invariant Systems01:23

Linear time-invariant Systems

773
A system is linear if it displays the characteristics of homogeneity and additivity, together termed the superposition property. This principle is fundamental in all linear systems. Linear time-invariant (LTI) systems include systems with linear elements and constant parameters.
The input-output behavior of an LTI system can be fully defined by its response to an impulsive excitation at its input. Once this impulse response is known, the system's reaction to any other input can be...

  • Information Technology
  • Computer Science

Background:

  • The expanding Internet of Things (IoT) security camera market faces significant personal information leakage risks due to security vulnerabilities.

  • A new permutation-based video encryption algorithm is proposed, utilizing a crypto-secure pseudo-random number generator to update the permutation list for each video frame.
  • The algorithm incorporates color channel separation to prevent situation deduction and employs pre-compression encryption to mitigate data loss from packet loss.

Main Results:

  • The proposed algorithm demonstrates robustness against known-plaintext attacks by dynamically updating permutation lists.
  • Color channel separation effectively prevents attackers from inferring situational information.
  • Pre-compression encryption enhances resilience against packet loss, ensuring data integrity.

Conclusions:

  • The developed algorithm offers enhanced security and privacy for video streams in IoT security cameras.
  • It overcomes key limitations of previous permutation-based encryption methods, providing a more secure solution for low-power devices.
