The fundamentals of the "Ring" could easily be restored within the context of Denić's remarkable sets; it wouldn't be hard to indicate, say, how the oil rig relates to Wotan's power.
It's hard to indicate a smile in an e-mail or an instant message unless you are willing to go the emoticon route, and then all is lost either way.
"It's hard to indicate what I mean, but, for example, if a girl in school likes a certain book, the boys can't like it for fear of being called gay or whatever, so that book becomes a girl's book," he said.
A Quiet Walk It is hard to find markers indicating that you've left Monaco and crossed into France.
Since this is hard to achieve, filters that indicate in this direction are useful.
Experimental: As Fig. 2 indicates, it is hard to distinguish between the two approaches using only measurements of sway angle and angular velocity.
If no label hypothesis is provided (as was the case for tissue embryological attribution, the uncovering of which was unsupervised), it is hard to imagine an unsupervised strategy that indicates the right tuning for unfolding the classes hidden in a nonlinear dataset.
For the impact of the added air cavity, the results indicate that it is hard to distinguish between with and without the cavity.
The above discussion indicates that it is hard to obtain the values of parameters b, k, r, β, and K when there exists a bifurcation at endemic equilibrium E ∗ ( S ∗, I ∗, Y ∗ ) for model (1.2).
The differences of down-hole pressures among cases with different perforation parameters are too small to be detected in the field, which indicates that it is hard to tell from the pressure record alone whether or not all the fractures are equally growing.
