In model theory, a branch of mathematical logic, an **existentially closed model** is a particular type of model that satisfies certain properties with respect to existential statements in a given theory.
Experimental techniques refer to the various methodologies and procedures used in scientific research and experimentation to gather data, test hypotheses, and validate theories. These techniques are essential for conducting rigorous and reproducible experiments across a variety of fields, including biology, chemistry, physics, psychology, and engineering. Here are some key aspects of experimental techniques: 1. **Experimental Design**: This involves planning an experiment to ensure that it effectively addresses the research question.
Exposure Action Values (EAVs) are specific levels of exposure to a particular hazardous agent, such as chemicals in the workplace, that require action to protect workers’ health and safety. They are part of a broader framework for managing occupational health risks and are often established by regulatory bodies or organizations specializing in occupational safety. In many countries, the concept of EAVs is used in conjunction with Exposure Limit Values (ELVs), which are the maximum allowable concentrations of harmful substances in the workplace air.
An Extended Finite State Machine (EFSM) is a computational model that extends the capabilities of a traditional finite state machine (FSM). While a traditional FSM consists of a finite number of states and transitions between those states based on input symbols, an EFSM incorporates additional features that provide greater expressive power.
External combustion engines (ECEs) are a type of heat engine in which the combustion of fuel occurs externally to the engine itself. Unlike internal combustion engines, where fuel is burned within the engine cylinder, external combustion engines generate heat through a separate combustion process that heats a working fluid (such as water or air) that then drives the engine's mechanical motion.
Fable II Pub Games is a collection of mini-games that was released in conjunction with the action role-playing game Fable II, developed by Lionhead Studios and published by Microsoft Game Studios. Launched in 2008, Fable II Pub Games allows players to engage in various gambling-style games that take place within the Fable universe.
Fail-safes in nanotechnology refer to mechanisms or strategies designed to prevent or mitigate potential risks associated with the use of nanomaterials or nanodevices. Due to the unique properties of nanomaterials, such as their small size, high reactivity, and the difficulty in predicting their behavior in biological and environmental systems, fail-safes are crucial for ensuring safety and preventing unintended consequences.
"Fallout: An American Nuclear Tragedy" refers to a book by author and historian Michael M. O'Rourke, published in 2021. The narrative explores the themes of nuclear warfare, its impacts on society, and the broader implications of nuclear policy in the U.S. context. The book delves into historical events, public policy, and cultural responses to the threat of nuclear weapons, examining how these factors have shaped American identity and consciousness.
False brinelling is a type of wear damage that occurs in rolling element bearings, typically caused by vibration or oscillation while the bearing is stationary or not rotating. This condition is characterized by the formation of indentations or pits on the raceways and rolling elements of the bearing. False brinelling can happen when a bearing is subjected to cyclical forces or vibrations, which can lead to localized micro-movements at the contact points between the rolling elements and the raceways.
False precision refers to the misleading impression of accuracy that occurs when a measurement or statement is presented with more detail or specificity than is warranted by the actual data. This can happen in various contexts, such as statistics, scientific measurements, or everyday reporting. For example, if a measurement is reported as 12.34567 meters, it may imply a high degree of precision.
Fangataufa is a small coral atoll located in the South Pacific Ocean, part of French Polynesia. It is situated in the Tuamoto Archipelago, which consists of a large number of islands and atolls. Fangataufa is known primarily for its historic significance, particularly as a site of nuclear testing conducted by France in the 1960s. The atoll was used as a testing ground for both atmospheric and underground nuclear tests, which had significant environmental and geopolitical implications.

The award is presented by the National Weather Association (NWA) and is intended to celebrate achievements that enhance public awareness and safety related to severe weather phenomena.
A Fermat number is a specific type of integer that can be expressed in the form: \[ F_n = 2^{2^n} + 1 \] where \( n \) is a non-negative integer. Fermat numbers were named after Pierre de Fermat, a French mathematician, who studied these numbers in the 17th century.

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!
We have two killer features:
  1. 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-calculus
    Articles 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.
