Relative Motion Analysis using Rotating Axes01:25

Relative Motion Analysis using Rotating Axes

492
Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame.
However, to express the relative position of point B relative to point A, an additional frame of reference, denoted as x'y', is necessary. This additional frame not only translates but also rotates relative to the fixed frame, making it...

Transformers with Off-Nominal Turns Ratios

183
In scenarios involving parallel transformers with disparate ratings, developing per-unit models requires accommodating off-nominal turns ratios. This situation arises when the selected base voltages are not proportional to the transformer’s voltage ratings. Consider a transformer where the rated voltages are related by the term a. If the chosen voltage bases satisfy a relationship involving term b, term c is defined as the ratio of these bases. This ratio is then substituted into the...

Transformers in Distribution System

132
Transformers in distribution systems can be broadly categorized into distribution substation transformers and other distribution transformers. They are crucial for stepping down high transmission voltages to levels suitable for distribution and end-user applications.
Distribution substation transformers come in various ratings and typically use mineral oil for insulation and cooling. To prevent moisture and air from entering the oil, some transformers use an inert gas like nitrogen to fill the...

Transformation

38
Microbial communities are dynamic environments where cell lysis releases free DNA into the surroundings. Other cells can take up this extracellular DNA through a process known as transformation.When a cell incorporates this foreign DNA into its genome, resulting in genetic modification, the process is known as transformation. Cells capable of this process are termed competent. Competence can be natural, as observed in certain bacteria and archaea, or artificially induced in the...

Vision01:24

Vision

53.7K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Transformers

1.1K
A device that transforms voltages from one value to another using induction is called a transformer. A transformer consists of two separate coils, or windings, wrapped around the same soft iron core. However, they are electrically insulated from each other.
The iron core has a substantial relative permeability. Therefore, the magnetic field lines generated due to the current in one winding are almost entirely confined within the core, such that the same magnetic flux permeates each turn of both...

    Area of Science:

    • Computer Vision
    • Artificial Intelligence
    • Machine Learning

    Background:

    • Supervised learning methods for video summarization rely on human-created summaries.
    • Existing methods often overlook inter-frame correlations and intra-frame attention for frame importance.
    • Efficient video browsing requires compact and perceptually relevant video summaries.

    Purpose of the Study:

    • To propose a novel transformer-based method for video summarization.
    • To address limitations in current methods by incorporating both inter-frame and intra-frame attention.
    • To improve the quality and relevance of generated video summaries.

    Main Methods:

    • Developed the spatiotemporal vision transformer (STVT), a novel transformer-based architecture.
    • STVT utilizes an embedded sequence module, a temporal inter-frame attention (TIA) encoder, and a spatial intra-frame attention (SIA) encoder.
    • Employed a multi-frame loss for end-to-end network training.

    Main Results:

    • The proposed STVT method effectively learns temporal inter-frame correlations using multi-head self-attention.
    • Spatial intra-frame attention is captured by the SIA encoder for improved frame representation.
    • STVT significantly outperforms state-of-the-art methods on the SumMe and TVSum datasets.

    Conclusions:

    • Simultaneously considering inter-frame and intra-frame information leads to superior video summarization performance.
    • The STVT model offers a promising advancement in generating human-perceptive and content-rich video summaries.
    • The source code for STVT is publicly available for further research and development.
