The hBN is kept fixed to mimic a bulk substrate.
A tin (Sn) wire (0.25 mm diameter, Goodfellow Ltd). is inserted in the capillary such that one end is kept fixed at 1 mm from the powered electrode.
This paper examines a control structure with two degrees of freedom, where the feedback is kept fixed while the prefilter contains adaptive features.
When solving evolution equations the optimal parameter may change with time resulting in a significant loss of accuracy if the parameter is kept fixed.
The node is kept fixed, and the apparent motions of the Sun and the Moon (top portion of the figure) are shown relative to the node.
When either the microwave frequency or the stationary field strength is varied and the other is kept fixed, the measurement of radiation absorbed as a function of the changing variable gives an electron paramagnetic resonance spectrum.
It was shown that the thermal resistance of the whole heat exchanger can be reduced by increasing the fin radius and decreasing the fin thickness, while the fin volume is kept fixed.
However, in current agent systems, the distributed blackboard architecture is kept fixed after its initial setting, which may influence the system performance when network topology or agent cooperation relations are changed during operation.
For the particular case of self-affine potential landscapes we show that a localization-delocalization transition reported recently only occurs, if the variance of the potential fluctuations is kept fixed for all system sizes.
We exploit this idea to study the influence of the degree of detalization of polymer chains on their structural properties as well as on the diffusive properties of the fullerene nanoparticle, whose detalization is kept fixed.
For these systems our simulations show that the prediction of the solvation (or disjoining) pressure when the chemical potential is kept fixed is different from that obtained when the total density is fixed.
