A consignee is the person or entity to whom goods are delivered or shipped. In the context of shipping and logistics, the consignee is typically the buyer or recipient of the goods. The role of the consignee can vary depending on the arrangement between the parties involved in the transaction. Key points about a consignee include: 1. **Recipient Role**: The consignee receives the goods from the consignor (the sender or seller) and is responsible for taking possession of them.
The IBM 3790 is an early model of a data entry and document processing system that was part of IBM's line of information technology products. Introduced in the 1970s, the IBM 3790 was primarily used for capturing and processing data from printed documents, utilizing a combination of optical character recognition (OCR) and keyboard input. The system was designed to automate data entry tasks, enhancing efficiency and accuracy in processing large volumes of information.
The Wiener-Khinchin theorem, also known as the Wiener-Khinchin theorem for the autocorrelation function, is a fundamental result in the field of signal processing and stochastic processes. It establishes a relationship between the autocorrelation function of a stationary random process and its power spectral density.
Frequency response refers to the output of a system or device (such as an electrical circuit, speaker, or filter) as a function of frequency, quantifying how that system responds to different frequencies of an input signal. It is typically represented as a graph showing the amplitude (gain or loss) and phase shift of the output signal relative to the input signal across a range of frequencies.
As of my last knowledge update in October 2023, "Alexander Eichenwald" does not appear to refer to a widely recognized public figure, concept, or term.
In linear algebra, a normal eigenvalue refers specifically to an eigenvalue of a normal matrix. A matrix \( A \) is defined as normal if it commutes with its conjugate transpose, that is: \[ A A^* = A^* A \] where \( A^* \) is the conjugate transpose of \( A \). Normal matrices include various types of matrices, such as Hermitian matrices, unitary matrices, and orthogonal matrices.
Martin Ryle was a renowned British radio astronomer, best known for his pioneering contributions to the field of astrophysics and for developing techniques that advanced radio telescope technology. He was awarded the Nobel Prize in Physics in 1974, along with Antony Hewish, for their work in the field of radio astronomy, particularly for their contributions to the development of a new type of telescope that allowed for the study of celestial objects.
A ballad stanza is a type of stanza commonly used in ballads, which are narrative poems that tell a story. The traditional form of a ballad stanza typically consists of four lines (quatrains) with a specific rhyme scheme and meter. The common characteristics of a ballad stanza include: 1. **Rhyme Scheme**: The typical rhyme scheme is **ABAB** or **ABCB**, where the second and fourth lines rhyme with each other.
TF-IDF stands for Term Frequency-Inverse Document Frequency. It's a statistical measure used primarily in information retrieval and text mining to evaluate the importance of a word in a document relative to a collection of documents, or corpus. The idea behind TF-IDF is to highlight words that are more significant in a particular document while downplaying words that appear frequently across many documents, which might not be as meaningful or informative.
The Arrhenius equation is a formula used in chemistry to express the temperature dependence of reaction rates. It quantifies how the rate of a chemical reaction increases with an increase in temperature and is commonly represented in the following form: \[ k = A e^{-\frac{E_a}{RT}} \] Where: - \( k \) is the rate constant of the reaction.
Solar transit refers to the passage of the Sun across a particular point in the sky, or more specifically, its movement along the ecliptic plane as observed from Earth. This can manifest in different contexts: 1. **Astronomical Context**: In astronomy, solar transit can refer to the transit of the Sun across the local meridian, which is the highest point the Sun reaches in the sky at a given location (solar noon).
Heliotropism is the phenomenon where plants or flowers orient themselves towards sunlight. This movement is often observed in sunflowers and other plants that display growth or movement in response to the direction of sunlight throughout the day. There are two main types of heliotropism: 1. **Positive Heliotropism**: This occurs when plants bend or grow towards the sun, maximizing their exposure to sunlight, which is essential for photosynthesis.
Tree representation by Ciro Santilli 40 Updated 2025-07-16
This section is about ways in which you can represent a tree.
Trees are a specific type of graph, so any graph representation also provides a way to represent a tree.
Therefore this section will focus only on methods specific to tress, and which cannot be used for graphs in general.
Otto Octavius, also known as Doctor Octopus or Doc Ock, is a fictional supervillain appearing in comic books published by Marvel Comics, primarily as an adversary of Spider-Man. The character was created by writer Stan Lee and artist Steve Ditko, making his first appearance in "The Amazing Spider-Man" #3 in 1963.
MINOS+ is a software tool developed for multi-objective optimization problems. Specifically, it is an extension of the original MINOS solver, which stands for "Modified Interior-Point Method for Nonlinear Programming." MINOS+ is designed to handle problems that can involve multiple conflicting objectives, allowing users to find a set of optimal solutions known as the Pareto front.
Recycling antimatter is not a widely established concept or technology, as antimatter is a rare and expensive substance currently produced only in small quantities in particle accelerators and laboratories. Antimatter consists of particles that have the same mass as regular matter but opposite charge and quantum spin properties. For example, the antimatter counterpart of an electron is called a positron, which has a positive charge.
"Comet Man" is a superhero character from American comic books, primarily published by the now-defunct publisher Atlas Comics in the 1970s. Created by writer Roy Thomas and artist Frank Brunner, Comet Man first appeared in "Comet Man #1" in 1976. The character, whose real name is John Ray, gains superhuman abilities after exposure to a comet's radiation. These powers often include flight, energy manipulation, and enhanced strength.

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.

  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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
