Exempel på hur man kan använda PERTURB i en mening

• Protoplanets are thought to form out of kilometer-sized planetesimals that gravitationally perturb each other's orbits and collide, gradually coalescing into the dominant planets.
• The fact that the Council of Europe had adopted this tune as the "Anthem of Europe" in January 1972 apparently did not perturb the Rhodesian government; John Sutherland and Stephen Fender comment that Rhodesia's choice proved deeply embarrassing for the UK's Labour government, whose leaders now had to respect a melody associated with Rhodesia when attending official European functions.
• It would encrypt a constant (zero), using the first 8 characters of the user's password as the key, by performing 25 iterations of a modified DES encryption algorithm (in which a 12-bit number read from the real-time computer clock is used to perturb the calculations).
• In other words, the fluctuation of the particle at rest has the same origin as the dissipative frictional force one must do work against, if one tries to perturb the system in a particular direction.
• internal validation or cross-validation (actually, while extracting data, cross validation is a measure of model robustness, the more a model is robust (higher q2) the less data extraction perturb the original model);.
• If the input impedance of the voltmeter is sufficiently large, the SVM probe should not perturb the operation of the operational sample.
• This was studied by Clint McCrory in his 1972 Brandeis thesis following a suggestion of Dennis Sullivan that one make "a general study of the Zeeman spectral sequence to see how singularities in a space perturb Poincaré duality".
• Gliese 65 can penetrate a conjectured Oort cloud about Epsilon Eridani, which may gravitationally perturb some long-period comets.
• During the approach, Earth will perturb Apophis from an Aten-class orbit with a semi-major axis of 0.
• Gliese 710 has the potential to perturb the Oort cloud in the outer Solar System, exerting enough force to send showers of comets into the inner Solar System for millions of years, triggering visibility of about ten naked-eye comets per year, and possibly causing an impact event.
• A number of minor annoyances also perturb him throughout the day: a fly lands on his cereal at breakfast, which he inadvertently eats; an insurance salesman named Ray comes to the door, to which Furrows responds by feigning interest and, shortly after promising to take out a number of policies, slams the door in Ray's face with the words "I'd rather be dead"; an automated survey about carpet cleaning calls him repeatedly; his boss' wife comes by to pick up a book he was writing, and he (eventually) tells her off.
• Tyrocidine appears to perturb the lipid bilayer of a microbe's inner membrane by permeating the lipid phase of the membrane.
• At the highest eccentricities, similar to the extreme values observed today or even slightly greater, Mars will perturb Hungaria asteroids and force them into ever more eccentric and unstable orbits when their ascending node is close in longitude to Mars's aphelion.
• The underlying cause of aneuploidy remains highly debated; however, entosis is shown to perturb cytokinesis (cytoplasmic division) and trigger the formation of aneuploid cells.
• Anything that perturb the interaction of KBP and Kif15 can block the cells at mitosis, and hence it can be therapeutically used to control Kif15 upregulated cancer cells.
• The enantioselectivity of CLAs derives from their ability to perturb the free energy barrier along with the reaction coordinate pathway that leads to either the R- or S- enantiomer.
• Gal's idea is to not precompute equally spaced values, but rather to perturb the points x so that both x and f(x) are very nearly exactly representable in the chosen numeric format.
• Reaction wheels provide a much steadier spacecraft from which to make observations, but they add mass to the spacecraft, they have a limited mechanical lifetime, and they require frequent momentum desaturation maneuvers, which can perturb navigation solutions because of accelerations imparted by the use of thrusters.
• The perturbing force caused by the oblateness of the Earth will in general perturb not only the orbital plane but also the eccentricity vector of the orbit.
• 005 solar masses, at which point the binary system is generally unable to perturb the disc strongly enough for gas to be further accreted onto the circumprimary and circumsecondary discs.
