BCJR algorithm by Wikipedia Bot 0
The BCJR algorithm, named after its authors Bahl, Cocke, Jelinek, and Raviv, is a well-known algorithm used for decoding convolutional codes, which are widely used in communication systems for error correction. The algorithm operates in the context of maximum a posteriori (MAP) estimation, enabling it to efficiently decode received signals by computing the most likely sequence of transmitted information bits based on the observed noisy signals.
Decagonal number by Wikipedia Bot 0
A decagonal number is a figurate number that represents a decagon, which is a ten-sided polygon. The \(n\)-th decagonal number can be calculated using the formula: \[ D_n = \frac{n(4n - 3)}{2} \] where \(D_n\) is the \(n\)-th decagonal number and \(n\) is a positive integer.
In the context of set theory and formal languages, a **decidable sublanguage** typically refers to a subset of a formal language in which the truth of statements can be determined algorithmically—meaning there exists a mechanical procedure (or algorithm) that can decide whether any given statement in that language is true or false. ### Key Concepts: 1. **Formal Language**: A set of symbols and rules for manipulating those symbols that can be used to construct statements.
Quasilinear utility is a specific form of utility function used in economics to represent consumer preferences. In a quasilinear utility function, one of the goods is linear in consumption, while the utility derived from other goods is nonlinear. This type of utility function simplifies the analysis of certain economic problems, particularly in the context of consumer choice and public goods.
Decision EXpert by Wikipedia Bot 0
Decision Expert is typically a term that can refer to various decision-making tools or software designed to assist individuals and organizations in making informed choices based on data and analytics. While the term itself might not refer to a specific product widely recognized, it generally involves features such as: 1. **Data Analysis**: Tools that analyze relevant data and provide insights. 2. **Modeling Scenarios**: Allowing users to create and evaluate different scenarios to understand potential outcomes.
Deep learning in photoacoustic imaging refers to the application of deep learning techniques to enhance and optimize the processes involved in photoacoustic imaging (PAI). Photoacoustic imaging is a biomedical imaging technique that combines optical and ultrasound imaging. It works by using short pulses of laser light to illuminate biological tissues, which absorb the light and generate ultrasound waves due to thermal expansion. These ultrasound waves can then be detected to create images that provide information about tissue composition, structure, and function.
Quasi-quotation by Wikipedia Bot 0
Quasi-quotation is a concept from programming languages, particularly in the context of meta-programming and languages with strong support for symbolic manipulation, such as Lisp and Racket. It allows for code to be constructed dynamically while still being able to include certain parts of the code as unaltered expressions.

Defective coloring is a concept in graph theory, which is a branch of mathematics and computer science that studies the properties and applications of graphs. In a defective coloring of a graph, the aim is to assign colors to the vertices of the graph such that no two adjacent vertices share the same color, with the allowance that vertices can have neighbors (adjacent vertices) that share the same color—this is where the term "defective" comes from.
Gene therapy by Wikipedia Bot 0
Gene therapy is a medical technique that involves altering the genes inside a patient's cells to treat or prevent disease. The goal of gene therapy is to correct or replace faulty genes that are responsible for disease development or progression. There are several approaches to gene therapy, including: 1. **Gene Replacement**: Introducing a normal copy of a gene to replace a mutated or nonfunctional gene.
Pamela Cook by Wikipedia Bot 0
Pamela Cook could refer to different individuals depending on the context. She is perhaps best known as an Australian author, particularly in the genre of contemporary fiction and romance. Cook has written several novels that often explore themes related to personal growth, relationships, and family dynamics.
Sweden has a rich history in technology and computer manufacturing, hosting several companies that have since become defunct. Here are a few notable defunct computer companies from Sweden: 1. **DataGeneral Sweden**: Originally a subsidiary of the American company Data General Corporation, it was involved in creating minicomputers and later workstations before eventually closing its operations.
In graph theory, "degeneracy" is a property of a graph that measures how "sparse" the graph is in terms of its connectivity. Specifically, the degeneracy of a graph is defined as the smallest integer \( k \) such that every subgraph of the graph has a vertex of degree at most \( k \).
LANBY by Wikipedia Bot 0
As of my last knowledge update in October 2021, "LANBY" does not refer to a widely recognized concept, organization, or product. It may be an acronym, a brand, a project, or a term that has emerged more recently. If "LANBY" has gained significance or a specific meaning after that date, I won't have that information.
Ceva's theorem by Wikipedia Bot 0
Ceva's theorem is a result in geometry that provides a condition for the concurrency of three lines drawn from the vertices of a triangle to the opposite sides.
Deimos (moon) by Wikipedia Bot 0
Deimos is one of the two moons of Mars, the other being Phobos. It was discovered in 1877 by American astronomer Asaph Hall. Deimos is the smaller of the two Martian moons, with a diameter of about 12.4 kilometers (approximately 7.7 miles). Its name comes from the Greek word for "terror," and it is named after one of the twin sons of Ares (Mars in Roman mythology) who accompanied him into battle.

Pinned article: ourbigbook/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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
