Journal of Fluids Engineering, 1940
Abstract The field of system governing lies between the problems of pulsating loads and electrical stability on the one hand and frequency or time control on the other. It is concerned with the short period swings or hunting action for which poor governors are usually responsible.

Field failures of electronic systems
Annual Proceedings on Reliability and Maintainability Symposium, 2002Results of a research project recently concluded at the Danish Engineering Academy are presented. The scope of the research was to investigate the field-failure pattern of electronic systems of some complexity. The project included a close survey of 10000 to 15000 electronic systems in use in Denmark.

Field-resolved infrared spectroscopy of biological systems
Nature, 2020The proper functioning of living systems and physiological phenotypes depends on molecular composition. Yet simultaneous quantitative detection of a wide variety of molecules remains a challenge1-8. Here we show how broadband optical coherence opens up opportunities for fingerprinting complex molecular ensembles in their natural environment ...

Phase diagrams of random-field Ising systems
Journal of Physics A: Mathematical and General, 1994We show that the random-field Ising model may be tuned to obtain two distinct scenarios of phase diagram topology. Explicit evidence for this is presented in a numerically exact analysis in three dimensions and on a Bethe lattice, which allows us to investigate the effects of temperature, coordination number, and asymmetry in the field distribution.

QUANTUM FIELD THEORY OF A DISSIPATIVE SYSTEM
Modern Physics Letters A, 1995Quantum dissipative scalar and fermionic fields are studied here from classical stochastic fields. These classical stochastic fields are the outcome of the relativistic generalization of Nelson's stochastic mechanics based on a new microlocal geometry.

Evolution of ring-field systems in microlithography
SPIE Proceedings, 1998"No sooner than we achieve a goal, we move the goalposts to create a new, more difficult one"1 Offner’s ring-field all-reflecting triplet was the first successful projection system used in microlithography. It evolved over several generations, increasing NA and field size, reducing the feature sizes printed from 3 down to 1 micron.

Magnetic field induced orientation of photosynthetic systems
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1972Abstract 1. 1. The fluorescence of aqueous suspensions of Chlorella, Scenedesmus, Euglena and spinach chloroplasts is preferentially polarized in a plane perpendicular to an external magnetic field of 10 kG or more. The ratio of the fluorescence intensity viewed perpendicular to the field to the intensity viewed parallel to the field varies from ...
