Communication01:03

Communication

8.8K
Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.

Communication

11.2K
Sharing information, concepts, and emotions to foster mutual understanding is communication. The sender, recipient, and transaction must be considered in this manner. The sender is the person who shares the message, the recipient is the person who receives and understands the message, and the transaction is the method used to deliver the message and the variables that affect the communication's context and surroundings. The nurse-client connection is built on therapeutic communication.

Sound Intensity00:58

Sound Intensity

4.8K
The loudness of a sound source is related to how energetically the source is vibrating, consequently making the molecules of the propagation medium vibrate. To measure the loudness of a source, the physical quantity of interest is the intensity. This is defined as the energy emitted per unit of time per unit of area perpendicular to the sound wave's propagation direction. Since the total energy is greater if the source vibrates for a longer duration and over a larger area, dividing the...

Neuronal Communication01:28

Neuronal Communication

3.5K
Neurons, the fundamental units of the brain and nervous system, communicate through complex electrochemical signals that underpin all cognitive and bodily functions. This communication is primarily facilitated by a process involving the generation and propagation of an action potential along the axon of the neuron. When the internal electrical charge of a neuron surpasses a certain threshold, an action potential is triggered. This rapid change in voltage travels swiftly along the axon to the...

Therapeutic Communication01:30

Therapeutic Communication

8.5K
Communication is a lifelong learning process. Through therapeutic communication, nurses can collect relevant assessment data, provide education and counseling, and interact during nursing interventions. Sending and receiving messages occur through verbal and nonverbal communication techniques and can happen separately or simultaneously.
Verbal communication depends on language or a prescribed way of using words so that people can share information effectively. The critical aspects of verbal...

Sound Intensity Level00:53

Sound Intensity Level

4.9K
Humans perceive sound by hearing. The human ear helps sound waves reach the brain, which then interprets the waves and creates the perception of hearing. The loudness of the environment in which a person is located determines whether they can distinguish between different sound sources.
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and...

    Area of Science:

    • Optical Engineering
    • Atmospheric Optics
    • Signal Processing

    Background:

    • Turbulent atmosphere causes optical wavefront distortions, leading to signal fading in fiber optics.
    • Adaptive optics (AO) can correct these aberrations using phase conjugation but requires difficult real-time wavefront measurements.
    • Conventional AO is challenging for optical communication scenarios due to measurement complexities.

    Purpose of the Study:

    • To present a novel phase-retrieval technique as an alternative to conventional adaptive optics for mitigating signal fading.
    • To indirectly determine phase wavefronts from focal-plane intensity measurements.
    • To enhance signal coupling efficiency in optical fibers affected by atmospheric turbulence.

    Main Methods:

    • A novel phase-retrieval technique is proposed, avoiding direct wavefront measurement.
    • The method iteratively optimizes speckle patterns in the focal plane.
    • Phases of individual speckles are updated to maximize received optical power.

    Main Results:

    • The technique successfully compensates for distorted phasefronts.
    • It significantly increases the coupled signal power.
    • The number of iterations required is substantially reduced, enabling use with commercial deformable mirrors.

    Conclusions:

    • The proposed phase-retrieval method offers an effective alternative to traditional adaptive optics for optical communication systems.
    • It demonstrates practical feasibility by achieving efficient phase compensation with reduced computational demands.
    • This approach enhances signal integrity and coupling efficiency in turbulent atmospheric conditions.
