AIRCRAFT PROGNOSTIC HEALTH MONITORING PULSE HMS PORTABLE

A novel adjustable transducer array for an ultrasonic scanning using low-cost portable data acquisition units has been developed at Northwestern University. However, these techniques usually require high-cost instrumentation and training.

Application of more advanced imaging or scanning techniques significantly improves the accuracy and resolution of ultrasonic measurements. Conventional techniques for crack or corrosion characterization are based on either echo-amplitude measurements or time-of-flight evaluation. Several technically difficult situations (bodies and evidence encased in cement and metal) are presented as a challenge to audience.Īs a part of an aircraft inspection, characterization of fatigue cracks and corrosion spots is a vital task to ensure airworthiness of airplane structures. Forensic science best practice requires the use of non-destructive testing whenever reasonably possible. Specialized field investigative services may be provided in the areas of clandestine drug laboratories and major crimes (firearms, biology, trace, arson/explosives). Common analytical divisions within criminalistics laboratories include blood alcohol testing, toxicology, narcotics, questioned documents, biology, firearms, latent fingerprints, physical and trace evidence sections. Laboratories associated with governmental public agencies are typically involved in criminal cases as opposed to civil cases, and those types of cases that fall within the jurisdiction of the particular agency. Criminalistics, one of the many sub-divisions of forensic science, is an applied science in which items of evidence are analyzed to provide investigative information and scientific evidence to be used in courts of law.
