NMR frequency pulling in magnetic systems

Czechoslovak Journal of Physics, 1996
Frequency pulling, the collective effect of the nuclear spin polarization on the hyperfine interaction, has been observed in various ordered magnets by comparing the NMR frequencies of doped, dilute radioactive nuclei and the host nuclei. In both the antiferromagnetic insulator54Mn-55MnCl2.4H2O and ferromagnetic cobalt metal60Co−59Co the effect is only

TOGI Pull-In and Connection Systems

Offshore Technology Conference, 1991
ABSTRACT A unique and prototype pull-in and connection system were developed for the TOGI project. The offshore pull-in of the 20" pipeline and service lines and cable were performed without any problems. The mechanical and electrical connections became more problematic than envisaged.

Six-Port Based Load-Pull System

2013
Chapter 4 provides a detailed treatment of six-port based setups for passive and active load/source-pull measurements, as well as a description of six-port based harmonic load/source-pull measurements. The load-pull measurements for on-wafer devices require special attention; therefore, an alternative approach for impedance and power flow calibration ...

Unified View of Pull Production Systems

2016
The operation and control characteristics of some control policies from basic to hybrid ones are described in this chapter. Basic control policies include Kanban, CONWIP, and Base-stock. The simplest is the CONWIP, which has only a single control parameter for the entire production line, whereas Kanban and Base-stock controls require one control ...

Conceptual Basis of Push-and Pull-Systems

2003
In numerous technical and scientific publications, cencerning areas of manufacturing and logistics, the terms "push" and "pull" are commonly used to characterise particular concepts of system configuration and coordination. But these publications frequently do not present push- and pull-concepts in a clear way, because they do not explicitly ...
