Nondestructive Evaluation an Integral Part of Engineering

Nondestructive Evaluation Courses for Undergraduate Engineering and Engineering Technology Students

Two nondestructive evaluation (NDE) laboratory-based courses were developed for Engineering and Engineering Technology (ET) students of Drexel University. The ultrasound NDE laboratory allows for participation in laboratory activities in two modes: the traditional face-to-face classroom mode for students on Drexel’s campus, and a real-time, Internet-based mode for those at remote locations. Dur...

Nondestructive Evaluation of Coatings

Bulk and Rayleigh (or surface wave) velocities of ultrasonic waves in chromium coatings on steel were measured and an experimental correlation was found between the surface velocity and the hardness. Since qualitative coating evaluation is commonly made using hardnesses as a guideline, the possibility is herewith presented of using the so und velocities of surface ultrasonic waves for this purp...

Sadness as an integral part of depression

Sadness is considered by numerous authors to be a core symptom of depression. Currently, many arguments exist for its particular importance in depressed patients. Sadness makes up part of the various definitions of the depressive syndrome, even if its presence is not required for diagnosis. Furthermore, it is closely linked to the other depressive symptoms, and has prognostic value, in particul...

Rijksuniversiteit Groningen VARIABILITY ENGINEERING AS AN INTEGRAL PART OF THE SOFTWARE PRODUCT FAMILY DEVELOPMENT PROCESS

A lthough it is practically impossible to overstate the importance of software in everyday life, achieving the full potential of software still proves difficult at best. Software engineering differs from established engineering disciplines such as electronics engineering or mechanical engineering due to the flexibility inherent to the software concept. In most engineering disciplines, the decom...
