Shamir's Secret Sharing is a cryptographic algorithm conceived by Adi Shamir in 1979. It is designed to securely distribute a secret among a group of participants, in such a way that only a certain threshold of them can reconstruct the secret. The main idea behind the scheme is to split the secret into pieces, or "shares," using polynomial interpolation.
"Réseau plate" is a term used in the context of geography and cartography, particularly referring to a flat network or grid system used for mapping and spatial analysis. However, it can also refer to technical specifications in fields like engineering or computer science regarding flat networking architectures.
The Bidirectional Reflectance Distribution Function (BRDF) is a fundamental concept in optics and remote sensing that describes how light is reflected at an opaque surface. It characterizes the way in which light is scattered from a surface when illuminated by a light source. Mathematically, the BRDF is defined as the ratio of reflected radiance in a specific direction to the incident irradiance from a specific direction.
Hyperspectral imaging is a technology that captures and processes information from across the electromagnetic spectrum. Unlike traditional imaging, which uses just a few bands of light (such as red, green, and blue), hyperspectral imaging collects data in many narrow bands, often hundreds or even thousands of them, across the visible, near-infrared, and sometimes even into the thermal infrared ranges.
In set theory, a **stationary set** is a concept related to the properties of infinite sets, particularly in the context of uncountable cardinals and the study of subsets of the following types: 1. **Stationary Set:** A subset \( S \) of a regular uncountable cardinal \( \kappa \) is called a stationary set if it intersects every closed and bounded subset of \( \kappa \).
Timation is a term that refers to a project developed by the U.S. government in the early 1980s aimed at creating a satellite-based navigation system. The name "Timation" is derived from "Time" and "Navigation," highlighting the system's focus on using precise timing for navigation purposes. The project was part of the broader efforts that eventually led to the development of the Global Positioning System (GPS).
Meltwater Pulse 1B refers to a significant rise in global sea levels that occurred approximately 14,600 to 12,700 years ago during the late Pleistocene epoch. It is part of a broader phenomenon known as the Meltwater Pulses, which are characterized by rapid increases in sea levels caused by the melting of ice sheets and glaciers at the end of the last Ice Age.
Chebyshev's bias refers to the observed phenomenon in number theory regarding the distribution of prime numbers in arithmetic progressions. Specifically, it describes the tendency for the number of primes in certain congruence classes to outnumber those in others, particularly when considering primes of the form \(a \mod q\), where \(a\) and \(q\) are coprime integers.
Past sea level refers to the historical fluctuations in sea level that have occurred over geological time scales and more recent history. These fluctuations are influenced by a variety of factors, including climate change, glacial and interglacial periods, tectonic activity, the volume of water in oceans and seas, and land subsidence or uplift.
Sea level rise refers to the increase in the average level of the world's oceans due to various factors, primarily driven by climate change. This phenomenon can have significant impacts on coastal environments, communities, and ecosystems. The main contributors to sea level rise include: 1. **Thermal Expansion**: As ocean water warms, it expands, contributing to rising sea levels. 2. **Melting Glaciers and Ice Sheets**: The melting of glaciers and polar ice sheets (e.g.
Triskaidekaphobia is the fear or phobia of the number 13. This irrational fear can manifest in various ways, such as avoiding situations involving the number 13, feeling anxious when it appears, or even believing that it brings bad luck. The superstition surrounding the number 13 has cultural and historical roots, with many people associating it with misfortune, particularly in Western cultures.
The "Book of the Zodiac" can refer to various texts or works related to astrology, astronomy, or mystical interpretations of the zodiac signs. These texts often explore the characteristics, traits, and symbolism associated with the twelve signs of the zodiac, which are based on the positions of celestial bodies at the time of a person's birth. The book might contain content ranging from astrological charts, horoscopes, and personality analyses to mythological stories and spiritual insights connected to each zodiac sign.
An "order type" refers to the specific instructions given by a trader to a financial intermediary, such as a brokerage or an exchange, to execute a trade in a financial market. Different order types determine how and when a transaction is executed. Here are some common types of orders: 1. **Market Order**: This order is executed immediately at the best available current price. It ensures that the trade is executed quickly, but the exact price at which the order will be filled may vary.
The Tempotron is a computational model of a neuron that simulates the learning mechanism for spiking neural networks. It was proposed to describe how biological neurons can learn to respond to specific patterns of input over time. In a Tempotron model, the neuron integrates incoming spikes (electrical impulses) from other neurons over time and can fire (generate its own spike) once a certain threshold is reached.
In mathematics, a prime signature typically refers to a specific way of representing numbers or elements related to prime numbers, but the term can also refer to concepts in different mathematical contexts. However, it is most commonly associated with number theory or algebra. One common use of the term "signature" in mathematics relates to the decomposition of integers: 1. **Integer Factorization**: In number theory, the prime signature of an integer can describe its prime factorization.
A Ruth–Aaron pair is a pair of consecutive integers, \( n \) and \( n+1 \), for which the sums of the prime factors of both integers are equal when counted with multiplicity. For instance, let's consider the numbers 714 and 715: - The prime factorization of 714 is \( 2 \times 3 \times 7 \times 17 \).
Unity Amplitude is a part of Unity Technologies' offerings, particularly focused on providing tools for analytics and user engagement in gaming and applications. It is designed to help developers track player behaviors, analyze user interactions, and optimize the overall user experience. Unity Amplitude enables game developers to gather insights from gameplay data, allowing for data-driven decision-making and enhancing game performance.
V-by-One US is a high-speed digital interface technology primarily designed for transmitting video and audio data. Developed by the company VESA (Video Electronics Standards Association), it is intended as a replacement for traditional interfaces like LVDS (Low-Voltage Differential Signaling) and supports high-resolution video displays.
The Chandra–Toueg consensus algorithm is a distributed consensus algorithm proposed by Tamer Chandra and Sam Toueg in their 1996 paper. It addresses the problem of achieving consensus among a group of distributed processes in the presence of failures, particularly in asynchronous distributed systems where processes can fail by crashing and asynchrony can lead to message delays.
The Hirschberg–Sinclair algorithm is a method used in the field of computer science, particularly in the area of combinatorial optimization and graph theory. It is primarily known for solving the problem of finding the longest common subsequence (LCS) between two sequences. This problem has applications in various fields such as bioinformatics, text comparison, and data deduplication. The algorithm is a space-efficient version of the dynamic programming approach to solving the LCS problem.

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.
