However, economic and technical design requirements often enforce low frequency structural vibration characteristics in work-pieces, especially in an area distanced from the tool holder.
[GP1] "We could not enforce [the frequency of cholesterol measurement].
The interesting feature is in the simplicity of the control which can enforce two natural frequencies (and two corresponding natural modes), to a single-mass, or single-degree-of-freedom (SDOF), system.
Then, a novel slice-sparse representation model of the joint narrowband array covariance data is proposed in the frequency domain to enforce joint sparsity in the concatenated covariance matrix of all frequencies.
The original action balance equation is modified to facilitate absorbing boundary conditions along the frequency direction; this modification enforces periodicity at the frequency boundaries so that the fast convergence of Fourier-collocation holds.
The payment rule is virtually impossible to enforce, however, and judging from interviews, is violated with some frequency.
To improve operations in the control centers and reduce the frequency of blackouts, Congress gave the Federal Energy Regulatory Commission the authority to enforce detailed new rules.
ISTANBUL — Azerbaijan has begun to enforce a law that bans foreign companies from broadcasting on national frequencies, effectively closing its airwaves to Radio Free Europe/Radio Liberty, Voice of America and the BBC.
The improbability of this reversal is enforced by the increased frequency of the codons: stop codons appear only once per gene, whereas glutamine is present many times per gene on average.
For the v2 array design, which includes bacterial probes, an additional minimum sequence complexity constraint was enforced, requiring a trimer frequency entropy of at least 4.5 (calculation described below).
