What is Boost: Definition and 137 Discussions

Boost is a set of libraries for the C++ programming language that provides support for tasks and structures such as linear algebra, pseudorandom number generation, multithreading, image processing, regular expressions, and unit testing. It contains 164 individual libraries (as of version 1.76).Most of the Boost libraries are licensed under the Boost Software License, designed to allow Boost to be used with both free and proprietary software projects. Many of Boost's founders are on the C++ standards committee, and several Boost libraries have been accepted for incorporation into the C++ Technical Report 1, the C++11 standard (e.g. smart pointers, thread, regex, random, ratio, tuple) and the C++17 standard (e.g. filesystem, any, optional, variant, string_view).

    Building a Simple 9V Boost Converter for a Spark Plug

    hi, i am pretty new with electronics, and i can't find any simple boost converter circuts on the enternet. i would like to make the circut THE MOST SIMPLE i can, with the fewest possible parts. for a power source, i have 9v-1w. for the output power, i would like to send a thin spark from 1...

    Powering motor with boost converter?

    Hi. I have a blower motor I am trying to run at 20v from a 12vdc system. At 12v it draws 12A, but I need it to get to a higher RPM. I'm not sure what the surge current is (turning on). Anyway, I was talking to someone else and they didn't think increasing the voltage with a BC would increase the...

    Lorentz boost and equivalence with 3d hyperbolic rotations

    I was thinking that if i have for example a boost in the direction of x, then the boost should be equivalent to an hyperbolic rotation of the y and z axes in the other direction. I don't know if it's true or not. Then I want to know if somebody knows this result or why is false? I was...

    Lorentz Boost Help: Why Use Hyperbolic Functions?

    I was reading a section on lorentz boosts and i need some help understanding what they did: the book starts off by defining the line element dS where: (dS)^2 = -(CΔt)^2 + dx^2 + dy^2 + dz^2 then they say: "consider the analogs of rotations in the (ct) plane. These transformations leave...

    Application of Noethers to Lorentz force Lagrangian with boost

    I've been slowly self studying Lagrangian topics, and have gotten to Noether's theorem. I've tried application of a Lorentz boost to all the terms in the Lorentz force Lagrangian (which is invariant with respect to boost since it has only four vector dot products). Then using Noether's...

    Time a fourth dimension? is a boost a rotation?

    is a boost a rotation of a four vector? if the boost rotates an object more into the time dimension, ywo things happen: it's velocity increases. it's length contract in the direction of its motion. does this make sense? thanks!
