    • Cam (Med) A curved wedge, movable about an axis, used for forcing or clamping two pieces together.
    • Cam (Med) A projecting part of a wheel or other moving piece so shaped as to give alternate or variable motion to another piece against which it acts.
    • Cam A ridge or mound of earth.
    • Cam (Med) A turning or sliding piece which, by the shape of its periphery or face, or a groove in its surface, imparts variable or intermittent motion to, or receives such motion from, a rod, lever, or block brought into sliding or rolling contact with it.
    • a Cam Crooked. "Corbe shoulder."

Century Dictionary and Cyclopedia
    • n cam A comb.
    • n cam A ridge, hedge, or long earthen mound.
    • n cam In machinery, a device for converting a regular rotary motion into an irregular, fast and slow, intermittent rotary or reciprocating motion. It properly includes the cam-wheel, plain or geared, the cam-shaft, the heart-wheel, the wiper, the wiper-wheel, and the eccentric. The simplest form is that of a heart-shaped, lobe-shaped, or otherwise eccentric wheel, which imparts motion to another wheel either by means of gearing or by rolling contact. Instead of following the irregular face of the cam-wheel, the friction-wheel may travel in a curved race or guiding path on the side of a cam-disk, as in the cam-wheel of a harvester. In another form of cam the face of the wheel is cut into gears or into projecting teeth that may engage another gear, or an arm or a pinion upon a shaft, to give a quickly changing rising and falling motion. Such cams are also called wiper-wheels, and are used to operate stamps and tilt-hammers. The heart-wheel accomplishes the same object, but In a less abrupt manner, while eccentric cams of various shapes may impart a slow thrust and quick return, as in many machine-tools. The wiper, a cam-shaped arm, is very generally used to operate the valves of beam-engines. The cam in some of its forms appears in a great variety of machines, wherever an irregular speed or motion or a rapid reciprocating motion is required, as in the harvester, printing-press, sewing-machine, etc. A cam-shaft is a shaft having tumblers or wipers. The heart-wheel is a heart-shaped cam. (See eccentric.) Cams for determining motion for cutting and tracing, as in certain machines, are called shaper-plates.
    • cam Crooked; bent or bending.

Chambers's Twentieth Century Dictionary
    • n Cam kam (mech.) a device for changing a regular rotary motion into a reciprocating motion, various forms of which are the cam-wheel and shaft, the heart-wheel, the wiper-wheel, and the eccentric.

In science:

As mentioned in Section 1, we plan to develop tests that are optimal at correctly specified densities, in the sense of Le Cam’s asymptotic theory of statistical experiments.
Optimal rank-based tests for homogeneity of scatter
This establishes the premise of Le Cam’s Third Lemma (Le Cam (1960); H´ajek and ˇSid´ak (1967)), the conclusion of which is that the limit law under Q of the random variable Tν is N (r, 1).
Covariate Balance in Simple, Stratified and Clustered Comparative Studies
We follow the mentioned above Pitman-Le Cam’s approach.
Hypotheses Testing: Poisson Versus Self-exciting
We introduce the asymptotic optimality of tests with the help of the following definition Le Cam (1956).
Hypotheses Testing: Poisson Versus Self-exciting
The asymptotic optimality of the test follows as well from the general theory (see, e.g., Le Cam (1956) or Roussas (1972)), because if we replace H1 by any simple alternative H∗ : u = u∗ , then the test ¯φT (cid:0)X T (cid:1) = χ{L(u∗ /√T ,X T )>bε} is the most powerful.
Hypotheses Testing: Poisson Versus Self-exciting
Since R ez d Q(z ) = 1, we can apply Le Cam’s notion of contiguity (Le Cam and Yang 2000, chapter 3) to conclude that E(m,n,pn ,qn )ψn (X) < 1.
Optimal Calibration for Multiple Testing against Local Inhomogeneity in Higher Dimension
By Le Cam’s first lemma [van der Vaart (1996), page 88], we conclude that the sequences of probability measures {Pψ 0+h/√n,ζ } and {P0 } are contiguous, for every ζ ∈ Ξ.
On asymptotically optimal tests under loss of identifiability in semiparametric models
This classical fact goes back to Le Cam (1970).
On combinatorial testing problems
Note that, under some regularity constraints, one can formally deduce some results for the 1-variable density and nonparametric regression models from results on the asymptotic equivalence (in Le Cam sense) of these models to the 1-variable Gaussian white noise model (see, e.g., , ).
