The Double Slide Controller is a new electronic music instrument that departs from the slide trombone as a model for its design. Going much beyond a mere simulation of its acoustic counterpart it introduces truly innovative features: two powerful and versatile sets of gesture driven interfaces actuated by the hands of the performer, as well as featuring two independent slides, one for each hand...

The Electric Slide Organistrum (Figure 1) is an acoustic stringed instrument played through a video capture system. The vibration of the instrument string is generated electromagnetically and the pitch variation is achieved by movements carried out by the player in front of a video camera. This instrument results from integrating an ancient technique for the production of sounds as it is the vi...

A machine is described which can perform the Gram stain. Comparison of slides stained by machine versus hand revealed no difference in reproducibility or accuracy. In addition to providing clean, dry, uniformly stained slides, the machine saves 24 sec per slide when compared with a hand staining technique.

Recently a powerful cryptanalytic tool—the slide attack— was introduced [3]. Slide attacks are very successful in breaking iterative ciphers with a high degree of self-similarity and even more surprisingly are independent of the number of rounds of a cipher. In this paper we extend the applicability of slide attacks to a larger class of ciphers. We find very efficient knownand chosen-text attac...

Before automatic exposure control was fitted to diagnostic X-ray sets, radiographers were faced with the problem of choosing the parameters that would give the best radiographic image. For a new X-ray set whose performance was unknown, this was no easy matter, and often required considerable trial and error because of the number of variables involved. To reduce the amount of work, special slide...
