Phased array ultrasonic testing on large forgings for defect characterization

Finkl-Steel Sorel specialises in delivering high quality forged steel to a wide array of Canadian and international customers. In order to ensure the quality of their product, each forging is individually inspected for flaws and internal irregularities using standard pulse-echo technique. A reliable inspection technique is paramount to reduce the number of rejected forgings. Forged […]

Use of Recycled concrete Aggregate to Produce Concrete Masonry Blocks

Concrete—the most common construction material in the world—represents the main component of construction and demolition waste. The excessive extraction of virgin aggregate from Canadian lands and water bodies destroys the habitats of many species and affects the natural flow of streams in lakes and rivers. One solution to address the growing solid waste challenge and […]

Optimal Selection of Data Augmentation Transformations

To achieve useful results in training deep neural network, one typically needs huge number of labelled images. In most practical cases, it is often time consuming, expensive and sometimes even near impossible to get the required numbers of labelled images. Data augmentation consists in a set of image processing techniques that can be applied to […]
