Presentation Objective: Excel in the subspecialty of Forensic Engineering.
Presentation Outcome: Learn how to perform forensic investigations, issue reports and provide expert testimony during depositions and trials.
Background: Professional Engineers more and more provide a service to lawyers, judges and juries within their field of technical competence. These professionals make up the growing number of technical experts on which our court system relies, when technical facts become too complex to be analyzed and understood by legal professionals and the general public which provides the members of the jury. In order to excel in this subspecialty of forensic engineering, one must have a basic understanding of the litigation process, how to perform forensic investigations, issue reports and provide expert testimony during depositions and trials.

A presentation from the webinar Advancements in Phased Array Scan Planning.
Scan planning is an integral, yet somewhat neglected step in the everyday Phased Array (PA) inspection process. Success in proper scan planning leads to reliable results, higher productivity, and ensures repeatability but can often be difficult due to the varying nature of the PA technique and its application.
In this presentation, learn advanced scan planning concepts, implementation of different PA inspections, and achieve a better overall understanding of the benefits and limitations of Phased Array.

Description of wind turbine blades
How ultrasonic phased array inspection works
The detection capabilities of ultrasonic phased array technology
The productivity of ultrasonic phased array technology
Conclusions
Phased Array Ultrasonic Testing (PAUT) is an advanced method of ultrasonic testing that has applications in medical imaging and industrial nondestructive testing. Common applications are to non-invasively examine the heart or to find flaws in manufactured materials such as welds.
An Introduction to Acoustic Pulse Reflectometry Inspection System (APRIS)Talcyon Pte Ltd
The patented Acoustic Pulse Reflectometry Inspection System (APRIS) is an advanced yet easy to use tool that overcomes the limitations of many conventional inspection techniques.
It provides reliable inspections of even the most challenging tube sizes and configurations thus increasing inspection cycle efficiency and operational cost savings.
APRIS is largely used in inspections of heat exchangers (eg: Boilers, Fin Fans, Condenser, Heaters, Economizers, Super Heaters, other heat exchangers, etc.).
Related industries include but not limited to oil and gas, chemical, power generation, marine, HVAC, petrochemical, food & beverage and paper & pulp.
A rhombic antenna is a broadband directional wire antenna co-invented by Edmond Bruce and Harald Friis, in 1931, mostly commonly used in the high frequency (HF) or shortwave band.

This is a sample research instrument used in a study titled Writing Proficiency of Junior Bachelor of Secondary Education (BSEd) and Bachelor of Elementary Education (BEEd) in Catanduanes State University S.Y. 2012-2013.
The ultrasonic generator converts the supplied alternating voltage of 50 Hz or 60 Hz to a frequency that corresponds to the operating frequency of the transducer.
The transducer then converts the released electric energy into mechanical acoustic oscillations causing the surrounding fluid to oscillate.
Each oscillation leads to an over-pressure phase or low-pressure phase in the fluid, depending on whether the transducer expands or contracts.
During the low-pressure phase, due to the fluid's limited tensile strength, small cavities form in the fluid; these so-called cavitation bubbles implode during the over-pressure phase.
When the cavitation bubbles implode at the surface to be cleaned, dirt particles are removIt is important at this stage to draw attention to the very important and significant difference between 6dBµV and 6dB. 6dBµV is another way of expressing a voltage measurement 0f 2µV. 6dB however is merely expressing a ratio – stating that one number is 6dB higher than another indicates that the first number has double amplitude of the second. So if the decibel is dimensionless, i.e it does not have a specific reference attached to it, then that decibel reading is not telling anything. To say this is double is quite meaningless without a reference – it must be double compared with something else.
It is very important to keep in mind that decibels should not be multiplied or divided. They are dB and should only be added or subtracted. To say for example that 36dBµV is twice as big as 18dBµV is in correct. The difference between these two values is 18dBµV which correspond to a ratio of 7.9. So the voltage amplitude of a signal of 36dBµV is not 2 times higher than the voltage amplitude of a signal of 18dBµV, its in fact, 7.9 times higher!
Lets apply this to the bearing:
In January, bearing “A” was measured with an ultrasound detector and the value was 10dBµV
In April, that same bearing measured 62dBµV.
62dBµV - 10dBµV = 52dBµV (factor of 400)
Therefore, from January to April, the ultrasonic signal from bearing “A” increased by a factor of 400 – probably the has already failed.

It is very important to keep in mind that decibels should not be multiplied or divided. They are logarithmic values and should only be added or subtracted. To say for example that 36dBµV is twice as big as 18dBµV is in correct.

Ultrasonic phased array testing is a powerful NDT technology and one whose use is growing rapidly in particular for the inspection of welds in small and large diameter pipelines.
This presentation comes from our webinar, Diverse Uses of Advanced Ultrasonic Inspection Technologies for Pipeline. It provides a brief introduction of ultrasound phased array testing and outlines the various benefits of encoded automatic testing (AUT) versus radiography (RFT) in terms of cost, user friendliness, and detectability.
