Stages of Sleep01:22

Stages of Sleep

1.5K
Sleep progresses through distinct stages, each characterized by specific brain wave patterns and physiological responses ranging from wakefulness to stages of non-rapid eye movement, known as non-REM, to rapid eye movement, referred to as REM. Understanding these stages helps in recognizing how sleep supports various bodily and cognitive functions.
Before sleep begins, in wakefulness, the brain exhibits primarily beta waves, which are high in frequency and low in amplitude, indicating alertness...

Power Distribution in Three-phase and Single Phase Circuits

662
Power distribution within electrical circuits is a foundational aspect of residential and industrial energy systems. While single-phase power is common in residential settings, three-phase power is the standard for industrial environments with heavy machinery. Each system is different and has advantages, and it's crucial to understand the underlying principles of power distribution and material efficiency.
Single-Phase Power Distribution:
Single-phase circuits are typical in household settings;...

Instantaneous Velocity - II01:10

Instantaneous Velocity - II

13.5K
Instantaneous velocity is the quantity that measures how fast an object is moving along its path. In other words, the instantaneous velocity of an object is the limit of the average velocity as the elapsed time approaches zero, or the derivative of displacement with respect to time. Like average velocity, the instantaneous velocity is a vector with the dimensions of length per unit time. Instantaneous velocity can have both positive and negative values. The instantaneous velocity can be...

Instantaneous Acceleration01:16

Instantaneous Acceleration

23.4K
Acceleration is in the direction of the change in velocity, but it is not always in the direction of motion. When an object slows down, its acceleration is opposite to the direction of its motion. Although commonly referred to as deceleration, this causes confusion in our analysis as deceleration is not a vector, and does not point to a specific direction with respect to a coordinate system. Therefore, the term deceleration is not used. For example, when a subway train slows down, it...

Instantaneous Power01:22

Instantaneous Power

938
Instantaneous power is important in electrical circuits, mainly when dealing with sinusoidal input. Instantaneous power, denoted as p(t), results from the multiplication of the instantaneous voltage (v(t)) across an element and the instantaneous current (i(t)) flowing through it. This relationship adheres to the passive sign convention and represents a fundamental principle in electrical engineering.

Instantaneous Velocity - I01:15

Instantaneous Velocity - I

29.7K
The average velocity during a time interval cannot tell us how fast or in what direction a particle is moving at any given time during the interval. To calculate this, it is important to know the instantaneous velocity, which is the velocity at a specific instant of time or at a specific point along the path. Instantaneous velocity is the quantity that measures how fast an object is moving along its path. In other words, the instantaneous velocity vx of an object is the limit of the average...

    Area of Science:

    • Neuroscience
    • Biomedical Engineering
    • Signal Processing

    Background:

    • Automatic sleep stage scoring using electroencephalogram (EEG) has been extensively researched but lacks clinical standardization.
    • Existing methods often fall short of satisfactory performance for routine clinical application.

    Purpose of the Study:

    • To develop a novel, robust EEG-based feature set for improved automatic sleep stage scoring.
    • To evaluate the efficacy of these features in a distributed decision-tree classifier for clinical sleep disorder studies.

    Main Methods:

    • Proposed novel EEG features: Shannon entropy of the instantaneous analytical form envelope and EEG frequencies.
    • Constructed a distributed decision-tree classifier using binary K-nearest neighbor classifiers.
    • Optimized decision-tree structure via brute-force search over feature combinations.

    Main Results:

    • Achieved high overall accuracies of 88.97% and 83.17% on two distinct sleep EEG datasets (healthy young adults and adults with sleep disorders).
    • Demonstrated superior performance compared to state-of-the-art classifiers on single-channel EEG data.

    Conclusions:

    • The proposed method offers a simple yet high-performing approach for automatic sleep stage scoring.
    • This technique shows significant potential for application in clinical sleep disorder research and diagnosis.
