Confidence is a well-known psychological quality that is relevant for performing at one’s best. Previous literature examined sources from which athletes derive their confidence, what behaviors coaches perceive to be the most effective at building c

On a worldwide basis there exist large stocks of by-products from the production of ferrous and non-ferrous metals. For example, in Scandinavia there is a site which currently has 60 000 tons of stainless steel trapped in slag waste. Even at current

It is impractical to achieve the desired combination of power and bandwidth from conventional electromechanical acoustic sources. However, these characteristics can be achieved by the use of pulsed power technology to generate high-power ultrasound (

With growing economic and environmental pressures, oil companies seek ways to increase the oil recovery from every well. Re-entry drilling of horizontal sidetracks from existing wells and multilateral drilling for new wells are techniques which help

A simulation suite, cueMAP, has been developed to facilitate the design of inspection processes and sparse 2D array configurations. At the core of cueMAP is a Total Focusing Method (TFM) imaging algorithm that enables computer assisted design of ultr

High power ultrasound can be used as a catalysis to enhance the efficiency of chemical reactions. The generation of cavitation accelerates the reaction. The ultrasonic system in sonochemistry is typically based on single-frequency transducers, with s

The geometry of composite piezoelectric ultrasonic transducers is typically regular and periodic with one dominant length scale. In many applications there is motivation to design transducers that operate over a wide bandwidth so that, for example, s

We present a method for plating FBG strain sensors with a strongly-bonded, hermetic nickel layer, without exposure of the fiber to corrosive environments. A 1 mu m thick, highly adhesive chrome layer is deposited onto bare fibers via evaporation. Add

It is possible to produce a high-performance, flexible 1-3 connectivity piezoelectric ceramic composite with conventional methods but the process is difficult and time-consuming. Extensive finite element modeling was used to design a piezocomposite s

Acoustic Barkhausen emission (ABE) and electromagnetic Barkhausen emission (EBE) have been measured during the magnetization of nickel. Of particular interest is the effect on the Barkhausen emission envelope as the microstructure of the material is
