(engineering)
A technique or device designed to bring itself into a desired state by means of its own action.

bootstrap

(operating system, compiler)
To load and initialise the operating system on a computer. Normally abbreviated to "boot". From the curious expression "to pull oneself up by one's bootstraps", one of the legendary feats of Baron von Munchhausen. The bootstrap loader is the program that runs on the computer before any (normal) program can run. Derived terms include reboot, cold boot, warm boot, soft boot and hard boot.

The term also applies to the use of a compiler to compile itself. The usual process is to write an interpreter for a language, L, in some other existing language. The compiler is then written in L and the interpreter is used to run it. This produces an executable for compiling programs in L from the source of the compiler in L. This technique is often used to verify the correctness of a compiler. It was first used in the LISP community.

Bootstrap financing has been a widespread solution (Ebben and Johnson, 2006; Winborg and Landstrom, 2001) that has allowed small firms to access a broader range of financing alternatives.
Further, Dyson and Shale (2010), state that the true efficient frontier lies within the confidence limits that are produced by bootstrap procedures.
Uma das discussoes sobre a utilizacao do metodo bootstrap refere-se ao tamanho da amostra padrao (populacao inicial), na qual uma conclusao que depende severamente de somente algumas observacoes poderia ser usualmente considerada com mais tentativas (replicas bootstrap) que uma que tem suporte em maior numero de observacoes (Davison e Hinkley, 1997).
For example, even though bootstrap modeling is primarily focused on the liability (reserve) risk portion of required capital, it can also provide valuable insights into the pricing risk portion of required capital (since it simulates historical triangles in addition to the possible future outcomes).
We repeat this procedure 50 times, each time drawing from the full month data set, generating 50 bootstrap resamples of the 750 observations.
Van Auken observed a "serious gap in the literature" (in apparent concurrence with the authors of this paper) and stated that "research on the use of bootstrap financing is limited" (Van Auken, 2005, p.
The bootstrap technique has proved to be a very useful tool in many fields and can be particularly interesting to assess the variability of the claim-reserving predictions and to construct upper limits at an adequate confidence level.
