Dynamic characteristics of a digital transducer
Proceedings of IEEE International Symposium on Circuits and Systems - ISCAS '94, 2002Sigma delta (/spl Sigma/-/spl Delta/) modulation is a technique that is widely used in a variety of signal processing and conditioning applications. This discrete data, closed loop, nonlinear device employs oversampling techniques to achieve a suitable signal to noise ratio.

Sextortion of Minors: Characteristics and Dynamics
Journal of Adolescent Health, 2018Sextortion (threats to expose sexual images to coerce victims to provide additional pictures, sex, or other favors) has been identified as an emerging online threat to youth, but research is scarce. We describe sextortion incidents from a large sample of victims (n = 1,385) and examine whether incidents occurring to minors (n = 572) are more or less ...

Keystroke dynamics: Characteristics and opportunities
2010 Eighth International Conference on Privacy, Security and Trust, 2010Significant research into the feasibility of keystroke dynamics as a potential biometric authentication method has taken place since the advent of computers. The studies have progressed from examining typing patterns on desktop keyboards using statistical pattern classifiers to mobile keyboards using neural networks as a pattern classifier. The studies

DYNAMICAL CHARACTERISTICS OF DISCRETIZED CHAOTIC PERMUTATIONS
International Journal of Bifurcation and Chaos, 2002Chaos theory has been applied to various fields where appropriate random sequences are required. The randomness of chaotic sequences is characteristic of continuous-state systems. Accordingly, the discrepancy between the characteristics of spatially discretized chaotic dynamics and those of original analog dynamics must be bridged to justify ...

Dynamic Pumping Characteristics of the Hemopump®
The International Journal of Artificial Organs, 1994While pumping blood with the Hemopump® in sheep, the ability of predicting the instantaneous pump flow from the pressure difference over the pump system and pump parameters was investigated. For rotational speed n between 300 and 475 revolutions per second (rps), maximum pump flow QO(n) at zero pressure difference, internal pump resistance R(n), and ...

Dynamic characteristics of centrifuges.
Aviation, space, and environmental medicine, 1995In specifications of high performance human centrifuges, different definitions of the term "G-load onset rate" occur. This paper compares four of these definitions and discusses the motivation and its advantages and disadvantages from the technical point of view.

Characteristics of Dynamic Problems
1996Abstract There are a variety of problems where the behaviour of soils in dynamic loading is of concern, but because of diversity in the areas and complexity in the conditions under which dynamic loads are applied, it is not easy to establish a hierarchy in the discipline and to put all problems in a proper perspective.
