Digital media as support for Technical Vocational Education and Training (TVET) learning processes have been increasingly tested in recent times. In Germany, for example, the Ministry for Education and Research and others have been supporting projects that develop and evaluate innovative didactical and technological models focussing on “Virtual Learning”, “Learning with Web2.0” or “Mobile Learn...

In this paper we will focus on a dual model of engagement in order to globally establish digital fabrication and making in education. We believe that digital fabrication and making in education will not spread and grow roots within the broad educational system without changes in policy on national and international level. We strive to expand the understanding of establishing digital fabrication...

Image watermarking has become an important tool for intellectual property protection and authentication. In this paper a watermarking technique is suggested that incorporates two watermarks in a host image for improved protection and robustness. A watermark, in form of a PN sequence (will be called the secondary watermark), is embedded in the wavelet domain of a primary watermark before being e...

Access to the spatial derivatives of an optical wave field can be used to enhance edge detection, focusing, and holographic imaging. It was recently shown that, by using digital holographic techniques, the Laplacian of an object field can be extracted. Here it is demonstrated that equivalent results can be found using two holograms captured at either two distances or with two appropriately rela...

Object: The gold standard for evaluating bone mineral density is dual energy x-ray absorptiometry (DEXA).  Prior studies have shown poor reliability using analog wrist X-rays in diagnosing osteoporosis. Our goal was to investigate if there was improved diagnostic value to visual assessment of digital hand X-rays in osteoporosis screening. We hypothesized that similar to analog counterparts, dig...

Superconductive single-flux-quantum (SFQ) circuit technology attracts attention as a next generation technology of integrated circuits because of its ultra-fast computation speed and low power consumption. In SFQ digital circuits, unlike CMOS digital circuits, a pulse is used as a carrier of information and the representation of the logic values is different from that in CMOS digital circuits. ...
