Self-Evaluation: Self-Enhancement and Self-Verification03:00

Self-Evaluation: Self-Enhancement and Self-Verification

5.8K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Range00:59

Range

14.1K
The range is one of the measures of variation. It can be defined as the difference between a dataset's highest and lowest values. For example, in the study of seven 16-ounce soda cans, the filled volume of soda was measured, thus producing the following amount (in ounces) of soda:
15.9; 16.1; 15.2; 14.8; 15.8; 15.9; 16.0; 15.5
Measurements of the amount of soda in a 16-ounce can vary since different subjects record these measurements or since the exact amount - 16 ounces of liquid, was not...

Uniform Depth Channel Flow01:27

Uniform Depth Channel Flow

573
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...

¹H NMR: Long-Range Coupling

2.7K
The coupling interactions of nuclei across four or more bonds are usually weak, with J values less than 1 Hz. While these are usually not observed in spectra, the presence of multiple bonds along the coupling pathway can result in observable long-range coupling.
In alkenes, spin information is communicated via σ–π overlap, as seen in allylic (four-bond) and homoallylic (five-bond) couplings. These coupling interactions are stronger when the σ bond is parallel to the alkene...

Variation: Normal Distribution, Range, and Standard Deviation

27.6K
In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

2.0K
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

    Area of Science:

    • Optics
    • 3D Imaging Technology
    • Holography

    Background:

    • Conventional holographic stereogram (HS) reconstructs 3D images using Fourier transforms, but suffers from low resolution.
    • This method is analogous to depth-priority integral imaging (II), limiting image quality.
    • Existing holographic techniques often face trade-offs between resolution and depth range.

    Purpose of the Study:

    • To propose and demonstrate a novel 'resolution priority' holographic stereogram (HS).
    • To enhance the resolution of reconstructed 3D images compared to conventional methods.
    • To improve the limited depth range of the proposed resolution priority HS.

    Main Methods:

    • Introduced a resolution priority HS concept based on resolution priority integral imaging (II).
    • Incorporated a quadratic phase term into the conventional Fourier transform for improved resolution.
    • Applied a multi-plane technique to simultaneously present multiple central depth planes, expanding the depth range.

    Main Results:

    • The proposed resolution priority HS significantly improves the resolution of reconstructed 3D images.
    • The addition of a quadratic phase term enhances image clarity.
    • The multi-plane technique effectively expands the achievable depth range.

    Conclusions:

    • Resolution priority HS offers superior 3D image resolution over conventional HS.
    • The multi-plane technique successfully addresses the depth range limitation.
    • Both simulation and optical experiments validate the effectiveness of the proposed high-resolution, enhanced-depth holographic stereogram.
