The center of mass (COM) is a point in a system of particles or a continuous mass distribution where the total mass of the system can be considered to be concentrated for the purpose of analyzing motion. It is the balance point of the mass distribution, meaning that if a system were to be suspended at this point, it would remain in equilibrium.
The Certificate Management Protocol (CMP) is a protocol used for managing digital X.509 certificates, which are commonly used for securing communications in various security protocols, including Secure Sockets Layer (SSL)/Transport Layer Security (TLS) and Internet Protocol Security (IPsec). CMP is defined in several specifications by the Internet Engineering Task Force (IETF), notably RFC 4210.

A chassis dynamometer is a type of testing equipment used to measure the power output and performance of a vehicle's engine and drivetrain while the vehicle is in a stationary position. Unlike an engine dynamometer, which tests only the engine, a chassis dynamometer assesses the entire vehicle, including the tires, transmission, and other components that influence performance. ### Key Features of a Chassis Dynamometer: 1. **Setup**: The vehicle is driven onto rollers that simulate road conditions.
A biclique attack is a type of cryptographic attack used primarily against ciphers and hash functions that exploit the structure of their underlying mathematical functions. This attack utilizes the concept of a biclique—a subset of a bipartite graph—where the nodes within the two sets can have connections (or edges) between them. The attack takes advantage of this structure to reduce the complexity of finding keys or collisions in modern cryptographic algorithms.
Chemical milling, also known as chemical etching or photochemical machining, is a manufacturing process used to remove material from the surface of a workpiece using chemical reactions. This technique is often employed in the production of metal parts, components, and complex geometries that would be difficult or costly to achieve using traditional machining methods.
Chemiluminescence is the production of light as a result of a chemical reaction. Unlike fluorescence or phosphorescence, where light is emitted after absorbing energy (usually from light), chemiluminescence generates light directly from the reaction itself. This phenomenon can occur in various biological and chemical processes. A common example of chemiluminescence is the light produced by fireflies.
Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
