Rapid changes in fluid saturation, characteristic of immiscible displacement, are difficult to measure accurately using gamma rays due to practical restrictions on source strength.
Mr. Doss estimated that 100,000 had been displaced in the past few days, although estimates of new displacements were difficult amid people who had moved two and three times.
Early stage design of precision flexure systems that utilize strain-based displacement sensing is difficult due to the strong coupling between the mechanical and sensing subsystems.
This filtering and unwrapping effect gives a spatially-continuous displacement, which is difficult to obtain from a field survey only.
Due to insecurity and the challenges of responding to conflict, controlling and understanding HAT spread because of displacement is extremely difficult.
This may result from the fact that more of the small circular chromosomes are probably present in the starting sample, are more likely than large chromosomes to survive extraction and purification processes intact, and strand displacement is more difficult in regions with increased GC content.
However, designing the specific device dimensions to obtain a specific device force-displacement capacity and response is difficult and no set design approach exists.
This is expected in that in case of large displacement between neighboring frames, it is difficult to estimate accurately the optical flow.
Providing adequate energy access is difficult in a displacement context, where political challenges, a shortage of energy specialists in the field, and limited private sector investment are a few of the many factors that prevent substantial improvements from reaching refugees.
However, this theory demands C1 continuity of transverse displacement at the element edges, which is difficult to satisfy arbitrarily in any existing finite element.
