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...

Self-Help Support Groups

360
Self-help support groups are voluntary, community-based organizations that provide a platform for individuals with shared concerns to exchange support, insights, and practical strategies for coping with life challenges. Typically led by group members or paraprofessionals, these groups form a cornerstone of mental health care, especially in reaching populations that are underserved by traditional healthcare systems.

Random and Systematic Errors01:20

Random and Systematic Errors

15.2K
Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...

Local Anesthetics: Chemistry and Structure-Activity Relationship

6.7K
Local anesthetics (LAs) are drugs that induce a temporary loss of sensation in a limited body area, preventing pain. Cocaine was the first local anesthetic discovered in the late 19th century. Cocaine is a benzoic acid ester obtained from the leaves of coca shrubs and was often used for its psychotropic effects. Cocaine was first isolated in 1860 by Albert Niemann. Sigmund Freud studied the physiological actions of cocaine. Carl Koller later introduced it into clinical practice in 1884 as a...

Systematic Sampling Method01:17

Systematic Sampling Method

13.4K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
Systematic sampling is one of the simplest methods...

Area of Science:

  • Gerontology and Health Informatics
  • Ubiquitous Computing and Artificial Intelligence

Background:

  • The global rise in older adults presents significant social, economic, and healthcare challenges due to increased chronic diseases and disabilities.
  • Ambient Assisted Living (AAL) aims to enable older adults to live independently longer, utilizing technologies like Human Activity Recognition (HAR) and Indoor Localization (IL).

Purpose of the Study:

  • To systematically review Human Activity Recognition (HAR) and Indoor Localization (IL) approaches, analyzing their methods, accuracy, and relevance to the Ambient Assisted Living (AAL) domain.
  • To explore the synergistic potential between HAR and IL for advancing AAL solutions.

Main Methods:

  • A systematic literature review was conducted, analyzing 27 papers sourced from six major scientific databases (ACM, IEEE Xplore, PubMed, Science Direct, Springer).
  • Papers were categorized based on their primary focus: HAR, IL, or the integration of both.

Main Results:

  • Analysis covered the types of methods and technologies used for HAR, IL, and data fusion, alongside reported accuracy metrics.
  • The review identified distinct approaches within HAR, IL, and integrated HAR-IL studies, detailing their specific technological implementations and performance.

Conclusions:

  • The relationship and mutual support between Human Activity Recognition (HAR) and Indoor Localization (IL) remain significantly understudied.
  • There is a substantial, yet largely untapped, potential for integrating HAR and IL to create more effective Ambient Assisted Living (AAL) solutions.
