Abstract Ultrasonic testing (UT) is increasingly combined with machine learning (ML) techniques for intelligently identifying damage. Extracting significant features from UT data is essential for efficient defect charact...

Abstract Full matrix focusing method of ultrasonic phased array has been proved with advantages of good signal-to-noise ratio and imaging resolution in the field of Ultrasonic NDT. However, it is still suffering from the...

Abstract A high-precision evaluation of ultrasonic detection sensitivity for a micro-crack can be restricted by a corroded rough surface when the surface microtopography is of the same order of magnitude as the crack dep...

As an aircraft component is subjected to tensile/torsional/bending forces and heat cycles during operation, non-destructive inspection programs have been mandated by aviation regulatory authorities and component manufact...

Increasing population and consumption patterns affect the volume, type, and characteristics of waste which vary and increase periodically. This increment must be accompanied by the management of waste transportation so t...

Food safety is a crucial issue in Indonesia, especially regarding the use of hazardous preservatives such as formaldehyde in street food. Manual monitoring of formaldehyde use is often ineffective, so an automated system...

An Automatic Guided Vehicle (AGV) is an automated vehicle used to support the delivery of food and beverages in restaurant service systems, where manual methods still carry risks of delays and spillage. This study design...

While Heavy Goods Vehicles (HGVs) are essential to the global economy, their massive size creates dangerous visibility gaps, or "blind spots," that place both drivers and other road users at risk. Traditional mirrors oft...

Despite manufacturers’ goal of molding single component products from plastics, the structures of some of the products are far too complex to be molded as a single piece. Therefore, assembly of subcomponents into the f...

Abstract Cracks, especially small cracks are difficult to be detected in oil and gas transportation pipelines buried underground or covered with layers of material by using the traditional ultrasonic inspection technique...

The slow evaporation method was used to produce sodium bromide-doped L-alanine (SBLA) single crystals at room temperature. Advanced techniques including dielectric, cyclic voltammetry (CV), Vickers microhardness, impedan...
