Fast Automatic Restoration (FAR) typically refers to a system or process designed to quickly restore data, systems, or applications to a normative state following an incident such as a failure, outage, or data corruption. The goal of FAR is to minimize downtime and ensure business continuity by providing a rapid recovery mechanism. Key elements of Fast Automatic Restoration may include: 1. **Automated Backups**: Regularly scheduled backups that can be automatically restored when needed.
Dynamic recrystallization (DRX) is a process that occurs in materials, particularly in metals, during deformation processes such as hot working or high-temperature straining. It involves the formation of new, strain-free grains within a deformed microstructure while the material is being subjected to mechanical stress. This process is essential for understanding the mechanical behavior of materials, especially under conditions where they reach temperatures that facilitate recrystallization.
Prepainted metal, often referred to as pre-coated metal or prefinished metal, is a type of metal substrate, usually steel or aluminum, that has been coated with a layer of paint or other protective finish before it is formed into final products. This process generally involves two main steps: 1. **Surface Preparation**: The metal is thoroughly cleaned and treated to ensure good adhesion and to prevent corrosion. This may include processes such as washing, phosphating, and applying a primer.
Continuous Cooling Transformation (CCT) refers to a metallurgical process that describes the changes in the microstructure of a material, usually steel, as it cools at a continuous, rather than an instantaneous or isothermal, rate. This process is significant in understanding how cooling rates affect the phase transformation and mechanical properties of steel.
Metal casting is a manufacturing process in which liquid metal is poured into a mold to create a specific shape or form upon solidification. This technique is one of the oldest known methods of shaping metal and is widely used in various industries, including automotive, aerospace, and construction, due to its ability to produce complex shapes with high precision.
In slang, "stringer" typically refers to a freelance journalist or writer who contributes articles or news stories to various media outlets on a temporary or irregular basis. These individuals often work independently rather than being employed full-time by a single publication. The term can also imply a certain level of expertise or niche focus, as stringers are usually expected to find and report on stories that may not be covered by larger media organizations.
Silver overlay is a decorative technique often used in jewelry, tableware, and other decorative items. The process typically involves applying a thin layer of silver over a base material, which can be made of metals such as brass or copper. This method provides the appearance of solid silver while being more cost-effective and lightweight. There are a few key points about silver overlay: 1. **Appearance**: The silver layer gives the item a shiny, attractive finish that closely resembles that of solid silver.
Peening is a mechanical process used to improve the properties of materials, primarily metals, through the application of a mechanical impact, which induces compressive stresses on the material's surface. This process enhances the material's fatigue resistance, increases hardness, and can help prevent cracking.
Slotted angle refers to a type of structural steel section commonly used in construction and manufacturing. It is characterized by its L-shaped profile with a series of slots or holes along its length. These slots allow for easy fastening and adjustment of components, making slotted angles versatile and useful in a variety of applications. Key features and uses of slotted angles include: 1. **Material Composition**: Typically made from mild steel or galvanized steel, slotted angles are strong and durable.
Metamaterials are artificially structured materials engineered to have properties not typically found in nature. They are composed of sub-wavelength structures, meaning these structures are smaller than the wavelength of the electromagnetic radiation they are designed to manipulate. This unique configuration allows metamaterials to affect waves in unconventional ways, leading to a range of novel properties and applications.
The "Metamaterials Handbook" typically refers to a comprehensive guide or reference work that covers the concepts, design, applications, and advancements in the field of metamaterials. Metamaterials are materials engineered to have properties not found in naturally occurring materials, typically by arranging structures at a scale smaller than the wavelength of the phenomena they are designed to manipulate, such as electromagnetic waves.
A chromatosome is a structural unit of chromatin, which is the material that makes up chromosomes in eukaryotic cells. It consists of a segment of DNA wrapped around a core of histone proteins, specifically containing a core histone octamer made up of two copies each of histone proteins H2A, H2B, H3, and H4, along with an additional molecule of the histone H1.
Wind run refers to the total distance that the wind travels over a specific period of time, typically measured in miles or kilometers. It's a valuable metric in meteorology and climatology, as it helps to quantify wind patterns and their potential impacts. Wind run is calculated by integrating the wind speed over time; for example, if a constant wind speed of 10 miles per hour is maintained for one hour, the wind run would be 10 miles.
An alcohol thermometer is a type of thermometric device that measures temperature using alcohol as the thermometric fluid. The alcohol, usually dyed for visibility, expands and rises in a glass tube when heated and contracts when cooled. The scale on the side of the tube allows users to read the temperature based on the level of the liquid within the tube.
Grasshopper is a type of robotic weather station designed to gather meteorological data. It typically consists of an array of sensors and instruments that measure various atmospheric conditions, such as temperature, humidity, wind speed and direction, precipitation, and atmospheric pressure. The unique aspect of Grasshopper systems often includes their mobility, as they can be designed to move to different locations to collect data in diverse environments.
A nephelometer is an analytical instrument used to measure the concentration of suspended particles in a fluid by determining the amount of light scattered by those particles. The basic principle behind a nephelometer involves passing a beam of light—typically from a laser or other light source—through a sample. When the light interacts with suspended particles in the sample, it scatters at various angles. The amount of light scattered at a specific angle (usually 90 degrees) is measured by a detector.

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.
