To increase the production rate, transmission distance and testing intensity and to decrease the ground detected difficulty of continuous wave mud signals, the valve orifice must be optimized to satisfy the requirements for the continuous sinusoidal pressure output.
Modeling approaches can provide new insights into the dynamics of plant topology, but they are often hampered by experimental difficulties in data collection on complex trees with numerous internodes, especially in tropical tree species that present the additional difficulty of continuous growth with no marked cessation.
That highlights the difficulty of continuous alignment of two different systems.
A similar problem faces causal set theory in the form of the 'inverse problem', which roughly amounts to the difficulty of getting continuous manifolds (with their corresponding symmetries) from a fundamentally discrete theory (see Wallden, 2010, for a good recent review of causal sets, including a discussion of this problem, on which progress has also been made).
Assembly algorithms devised specifically for the sequencing of less diverse haploid and diploid genomes by short reads tend to fare poorly on data derived from variant populations such as viruses, both because of the difficulty of separating continuous variation from error, and because of other process-related challenges [ 2].
Apparently, such "sparse" SMG parameters can hardly represent the continuous muscle behaviors, and it is highly desirable to overcome the technical difficulty of automatically extracting continuous SMG patterns prior to the comparisons between SMG and EMG/MMG.
Given the difficulty of ASLR in continuous, spontaneous tasks [15], recognition-based annotation tools have still low performance - or rather preliminary for the case of the face [13, 25].
PEO was used as a cospinning component in the chitosan solution due to the difficulty of forming the continuous fibers without structural imperfections from neat chitosan in the electrospinning.
The difficulty of providing a continuous supply of potassium iodate and the poor iodation technologies in many small-scale salt producers could be factors in the shortage of I-salt in households and the iodine variability observed in this survey [ 14, 27].
Although prosthetics and other brain-powered devices have been around for some time, José del R. Millán of the Ecole Polytechnique Fédérale de Lausanne in Switzerland said that one difficulty is the amount of continuous concentration required to use them.
In 1958, Major General Yitzhak Rabin addressed the issue; he felt that the Egyptian stop at Isdud was the result of technical difficulties, following fifteen days of continuous movement, including battles along the way.
