In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Parallel Processing

The brain processes sensory information rapidly due to parallel processing, which involves sending data across multiple neural pathways at the same time. This method allows the brain to manage various sensory qualities, such as shapes, colors, movements, and locations, all concurrently. For instance, when observing a forest landscape, the brain simultaneously processes the movement of leaves, the shapes of trees, the depth between them, and the various shades of green. This enables a quick and...

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

Processes of Self-Presentation

Effective self-presentation is a central component of social interaction and identity construction. It relies on the dynamic processes of defining the situation and engaging in self-disclosure. These mechanisms help individuals navigate social context expectations and manage how others perceive them, fostering mutual understanding and relationship development.Defining the SituationSocial situations are shaped by collectively understood frames—a set of widely understood rules or...

Isothermal Processes01:21

Isothermal Processes

5.0K
A thermodynamic process that occurs at constant temperature is called an isothermal process. Heat slowly flows into the system or out of the system to maintain thermal equilibrium. Processes involving phase changes like water evaporation into steam or freezing water into ice at a constant temperature are examples of Isothermal Processes.
An ideal gas can also undergo isothermal expansion or compression.
For example, consider 1 mole of an ideal gas inside an isolated cylinder at initial volume V...

Area of Science:

  • Biomedical Engineering
  • Signal Processing
  • Pediatrics

Background:

  • Recent decades have seen significant advancements in video and sound acquisition and processing technologies.
  • These technologies have found numerous applications within the biomedical field, particularly in pediatrics.

Purpose of the Study:

  • To review the state-of-the-art in video and audio processing advancements in pediatrics.
  • To evaluate the potential application of these technologies for monitoring in the neonatal intensive care unit (NICU).

Main Methods:

  • A comprehensive review of over 150 papers on video and audio processing was conducted.
  • Clinical applications were categorized by patient cohort (newborns, infants, toddlers, preterm newborns).
  • Processing methods, including data acquisition, feature extraction, and characterization, were analyzed.

Main Results:

  • Video processing, automated since the 2000s, primarily characterizes infant motion, respiration, heart rate, and facial features.
  • Audio processing focuses on cry analysis, evolving from induced-pain cries to spontaneous cries using frequency-based features.
  • Non-cry audio signals are also discussed.

Conclusions:

  • Despite improvements in automated processing, the NICU environment presents challenges for fully automated analysis of extended recordings.
  • Potential solutions to overcome these limitations are proposed.
