Our objects of study are infinite sequences and how they can be transformed into each other. As transformational devices, we focus here on Turing Machines, sequential finite state transducers and Mealy Machines. For each of these choices, the resulting transducibility relation ≥ is a preorder on the set of infinite sequences.

Fundamenta Informaticae, 2015
We discuss simple functional transductions defined by invertible Mealy automata under iteration and in particular the question when the orbit relation defined by iteration is rational. We identify a class of these automata that has relatively complicated orbits, yet some of them are still orbit rational and discuss a number of decision problems ...

European Journal of Radiology, 1998
Sonography is facing a new technological revolution. Recent advances in ultrasound technology are increasing spatial, contrast and vascular resolution. Transducers play an important role in achieving these improvements; their technology is widely reviewed in this paper. Physics and technology relate to image quality and its clinical potentials.

20th Annual Symposium on Foundations of Computer Science (sfcs 1979), 1979
In this paper we study bijective a-transducers. We derive necessary and sufficient conditions on pairs of regular sets (R,S) such that a bijective a-transducer, mapping R cnto S exists. The results obtained allow the systematic construction of an a-transducer, mapping a set R onto a set S bijectively for surprisingly "different" regular sets R and S.

Review of Scientific Instruments, 1948
A description is given of a transducer which utilizes, for the transformation of sonic to electrical energy, the electrokinetic potential developed by the movement of a fluid through a porous solid. The construction and calibration of the transducer are discussed, and results of measurements of the pressure fluctuations in oil pipe lines are presented.

An Electromechanical Transducer
Transactions of the American Institute of Electrical Engineers, 1951As the telemetering art progresses under the impetus of both aircraft and industrial needs, the requirement for accurate transducing becomes more and more important. This article describes a null-balance type of transducer which is inherently capable of achieving an accuracy comparable to that of present-day transmission links.

Transducers III—Other Transducers
1996Crystals have always had a fascination for people. Are not diamonds a girl’s best friend? Their perfect shapes, their colours and the way they can be grown from a clear solution have long had a fascination. They have been (and are) involved in magic and sorcery and ‘new age’ religion. But they also have considerable scientific importance.
