RTCM SC-104 refers to a set of standards developed by the Radio Technical Commission for Maritime Services (RTCM) for Differential Global Navigation Satellite System (GNSS) applications. Specifically, RTCM SC-104 is focused on the format and protocols used for transmitting differential correction data to enhance the accuracy of GNSS positioning.
English Qaballa (often spelled "Kabbalah") refers to a modern interpretation and adaptation of the ancient Jewish mystical tradition known as Kabbalah, which explores the nature of the divine and the universe through various symbolic and esoteric teachings. While traditional Kabbalah is rooted in Jewish texts like the Torah and the Zohar, English Qaballa often incorporates elements from various esoteric traditions, including Western occultism, Hermeticism, and other mystical philosophies.
Onomancy is a form of divination that involves interpreting the meanings of names. The practice stems from the belief that a person's name can reveal insights about their character, fate, or destiny. Different cultures and traditions may have varying methods of interpreting names, often looking into the meanings of the individual components of a name or its numerical value (as in numerology).
Tetraphobia is an irrational fear of the number four. This fear is particularly prominent in some East Asian cultures, where the number four is often associated with bad luck or death. This superstition is partly due to the fact that the word for "four" has a similar pronunciation to the word for "death" in languages such as Chinese and Japanese.
In the context of set theory and logic, an **admissible ordinal** refers to a certain kind of ordinal that is used to define and study the properties of *admissible sets* and *admissible theories* in the framework of *admissible infinitary logic*.
As of my last knowledge update in October 2023, the largest known prime number is \(2^{82,589,933} - 1\). This prime number was discovered on December 7, 2018, as part of the Great Internet Mersenne Prime Search (GIMPS) project. It has 24,862,048 digits. Please verify this information with a current source, as new prime numbers could have been discovered since then.
Belphegor's prime is a palindromic number that is notable for its interesting structure. It is represented as follows: \[ 1000000000000066600000000000001 \] This number is noteworthy for several reasons: 1. **Palindromic Nature**: It reads the same forwards and backwards.
Mills' constant is a mathematical constant used in number theory, particularly in the context of prime numbers. It is defined as the smallest real number \( A \) such that the expression \( \lfloor A^{3^n} \rfloor \) yields a prime number for all positive integers \( n \). The value of Mills' constant is approximately: \[ A \approx 1.
A prime k-tuple is a specific arrangement of k distinct prime numbers that possess certain properties or characteristics. In the context of number theory, the term often refers to tuples of prime numbers that exhibit specific arithmetic patterns or share particular gaps. One of the most famous examples of prime k-tuples is the concept of "twin primes," which are pairs of prime numbers that differ by 2 (e.g., (3, 5) and (11, 13)).
A Zero-order hold (ZOH) is a method used in digital signal processing to convert a discrete-time signal into a continuous-time signal. The basic idea is to hold each sample value constant for a specified period until the next sample value is available. This means that the output of the ZOH circuit remains at the same amplitude level during each sample period, resulting in a piecewise constant waveform.
Firearm actions refer to the mechanism that handles the cycling of ammunition in a firearm. The action of a firearm is responsible for loading, firing, and ejecting cartridges. There are several types of firearm actions, each with its own characteristics and operational principles. Here are the main types: 1. **Bolt Action**: Commonly found in rifles, a bolt action requires the shooter to manually operate a bolt to chamber a new round after firing. This design is known for accuracy and simplicity.
Termination algorithms, often discussed in the context of computer science and mathematics, refer to methods or techniques used to determine whether a given computation, process, or algorithm will eventually halt or terminate rather than continue indefinitely. The concept is particularly important in various fields, including: 1. **Theoretical Computer Science**: Ensuring that algorithms will terminate is crucial, especially for recursive functions and programs.
Cristian's algorithm is a method used in computer networks for synchronizing the clocks of different systems over a network. Developed by the computer scientist Flavio Cristian in the 1980s, it is particularly useful in distributed systems where maintaining a consistent time across multiple devices is critical. The basic idea of Cristian's algorithm involves a client and a time server. The process generally follows these steps: 1. **Request**: The client sends a time request to the time server.
Weak coloring is a concept from graph theory related to the assignment of colors to the vertices of a graph. Unlike standard vertex coloring, where adjacent vertices must be assigned different colors, weak coloring relaxes this constraint. In a weak coloring of a graph, two vertices can share the same color as long as there is no edge directly connecting them. This means that any two vertices that are not adjacent can be colored the same.
P2PTV stands for Peer-to-Peer Television. It is a technology that allows users to stream television content over the internet directly from one another rather than through traditional broadcasting methods or centralized servers. In a P2PTV network, users share their bandwidth and resources, effectively distributing the load and reducing the need for centralized content delivery networks.
The Rocha–Thatte cycle detection algorithm is a method used in the context of graph theory, particularly for detecting cycles in directed graphs. It is often referenced in applications involving logic programming, database theory, and knowledge representation. The algorithm provides a way to efficiently determine whether there are cycles in a directed graph, which is essential for many computational problems where cycles can affect processing or lead to infinite loops.
Julijana Gjorgjieva is a prominent figure, often recognized for her contributions in a specific field, but without additional context, it's challenging to provide precise information about her. As of my last update in October 2023, there may have been developments or changes related to her career or activities.
Models of neural computation refer to theoretical frameworks and mathematical representations used to understand how neural systems, particularly in the brain, process information. These models encompass various approaches and techniques that aim to explain the mechanisms of information representation, transmission, processing, and learning in biological and artificial neural networks. Here are some key aspects of models of neural computation: 1. **Neuroscientific Models**: These models draw from experimental data to simulate and describe the functioning of biological neurons and neural circuits.
The Softmax function is a mathematical function that converts a vector of real numbers into a probability distribution. It is commonly used in machine learning and statistics, particularly in the context of multiclass classification problems. The Softmax function is often applied to the output layer of a neural network when the task is to classify inputs into one of several distinct classes.

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.
