Latent heat is energy gained or lost when a substance changes state, measured in joules. Molecules move differently in gas, liquid, and solid states, and excess energy is released as latent heat. This energy is felt in sweat evaporating and can cause thunderstorms and hurricanes. Latent heat is the name given to the energy that […]
Latent fingerprints are left accidentally by sweat on the hands and feet, and can be exposed using fingerprint powder or fumes. Analysis of fingerprints can provide evidence about the offender or crime. The Integrated Automatic Fingerprint Identification System (IAFIS) is a national database used by police investigators to obtain more information about fingerprints found at […]
Latent variables are undefined elements in statistical analysis and computer science. They can be hidden or hypothetical and are often excluded from constructs. Latent variable models compare observed variables to latent ones to understand underlying conditions. They are important in research but can be complicated to model. A latent variable is a variable that cannot […]
Latent defects are hidden defects that cannot be discovered during routine inspections. Liability law can be affected by these defects, and in some cases, the seller may be liable. If there is no clause in the contract, the buyer may have to take legal action. Latent construction defects are particularly costly, and insurance companies offer […]
To become a latent print examiner, apply for an open position with a local government agency that requires a certain amount of college-level forensic training and prior experience examining fingerprints. Some jurisdictions require a degree in science or criminal justice. Classroom training, work experience, and certification may also be required. Volunteering can help gain experience. […]
Latent learning is the ability to learn without reward, where an organism learns from observation and can express that ability later. An experiment with mice showed that reinforcement isn’t always necessary for learning. This theory contrasts with stimulus-response association theory influenced by Pavlov’s classical conditioning. Latent learning is a theory in psychology that describes learning […]
A latent impression examiner uses chemical and physical techniques to identify and analyze digital impressions found at a crime scene. They compare these impressions with those of a suspect to confirm or eliminate suspicion. Certification through the International Association of Identification is generally required for this job. A latent impression examiner is a crime scene […]
