Effective Radiated Power (ERP) is a measure used in telecommunications, particularly in radio broadcasting, to quantify the power emitted by an antenna in a specified direction. It takes into account the power supplied to the antenna and the antenna's gain relative to a standard reference antenna, typically an isotropic radiator (which radiates equally in all directions).
"An Illustrated Book of Bad Arguments" is a book by Alyssa Nassner that uses illustrations and simple explanations to highlight common logical fallacies and errors in reasoning. The book's aim is to educate readers about these fallacies in a visually engaging way, helping them to recognize flawed arguments in everyday discussions, debates, and media. Each logical fallacy is presented with a brief description and an accompanying illustration, making the concepts easier to understand and remember.
The Atiyah–Segal completion theorem is an important result in algebraic topology and representation theory, specifically in the context of stable homotopy theory and the study of equivariant stable homotopy types. In general, the theorem pertains to the completion of a space (or a category) in relation to certain types of groups (like finite groups), and it often deals with cohomology theories.
The Atomic Energy Research Establishment (AERE) is typically associated with the United Kingdom and was originally established in the early 1950s. It is part of the UK Atomic Energy Authority (UKAEA) and serves as a center for nuclear research and development. AERE was primarily focused on areas such as nuclear physics, reactor design, and materials research related to atomic energy.
Automated theorem proving (ATP) is a branch of artificial intelligence and mathematical logic concerned with the development of algorithms and software that can automatically prove mathematical theorems. The goal of ATP systems is to determine the validity of logical statements and derive conclusions based entirely on formal logical reasoning, without human intervention.
The general equation of heat transfer can be described through different modes of heat transfer: conduction, convection, and radiation. Each mode has its own governing equations, but the principle behind them is the conservation of energy.
Back scattering alignment generally refers to techniques used in various fields such as optics, telecommunications, and radar. However, it can often be seen in contexts like wireless communication and network design. In the context of wireless communications, back scattering alignment could relate to methods for ensuring that signals reflected or scattered back toward a source maintain coherence and alignment for optimal reception. This may involve manipulating the physical medium or the properties of the transmitting and receiving equipment to maximize the efficiency of the signal.
Dropleton is a term sometimes used to describe a state of matter that exhibits properties similar to a liquid droplet, particularly in the context of condensed matter physics. It often refers to a type of quasiparticle that can form under certain conditions, such as in exciton fluids or other phenomena related to electronic systems.
Dynamic Mode Decomposition (DMD) is a data-driven technique used in the analysis of dynamical systems, particularly for identifying patterns and extracting coherent structures from time-series data. It was introduced as a method for analyzing fluid flows and has since found applications in various fields such as engineering, biology, finance, and more. ### Key Concepts: 1. **Data Representation**: DMD decomposes a set of snapshots of a dynamical system into modes that represent the underlying dynamics.
"Edisonade" is a term used to describe a subgenre of speculative fiction, particularly science fiction, that emerged in the late 19th and early 20th centuries. The term is derived from the name of Thomas Edison, the famous inventor and businessman, as well as other contemporary inventors and scientific figures. Edisonades typically feature young protagonists, often boys or young men, who are inventors or amateur scientists.
An electron gun is a device that generates and emits a stream of electrons, typically in a vacuum environment. It consists of several key components that work together to produce and control a focused electron beam. Electron guns are commonly used in various applications, including: 1. **Cathode Ray Tubes (CRTs)**: In traditional television sets and computer monitors, electron guns are used to direct beams of electrons onto a phosphorescent screen, creating images.
An electron spectrometer is an analytical instrument used to measure the energies and distributions of electrons ejected from a material when it is bombarded with a source of energy, such as X-rays or ultraviolet light. It is widely used in fields such as material science, surface science, and solid-state physics to study the electronic structure and properties of materials.
Elizabeth Rogers' "Virginal Book," also known as "The Parthenia or The Virginal Book," is a collection of music for the virginal, a keyboard instrument popular during the Renaissance and early Baroque periods. Compiled by Elizabeth Rogers in the early 17th century, the book features a variety of pieces, including dances, variations, and other compositions suitable for performance on the virginal.
Betweenness centrality is a measure used in graph theory and network analysis to quantify the importance of a node (or vertex) within a network based on its position in relation to other nodes. It specifically assesses how often a node acts as a bridge along the shortest paths between two other nodes. ### Definition For a given node \( v \), betweenness centrality is calculated as follows: 1. **Identify all pairs of nodes** in the network.
A Process Control Network (PCN) is a specialized type of network designed to manage and control industrial processes and systems. It is typically used in manufacturing, energy, water treatment, and other sectors where automation and real-time process control are critical. Here are some key characteristics and components of a PCN: ### Key Features: 1. **Real-Time Communication**: PCNs facilitate low-latency communication between devices and systems to ensure timely data exchange for monitoring and control of processes.
A billion is a numerical value that represents one thousand million, or \(1,000,000,000\). It is commonly used in various fields such as finance, economics, and statistics to quantify large amounts. In the short scale, which is used in the United States and most English-speaking countries, one billion is defined as \(10^9\).
A **Boolean matrix** is a matrix in which each entry is either a 0 or a 1, representing binary values. In a Boolean matrix: - The value **0** typically represents "false" or "no," while the value **1** represents "true" or "yes." Boolean matrices are often used in various fields, including computer science, mathematics, and operations research.
Quantitative analysis of behavior refers to the use of numerical and statistical methods to measure and analyze behavioral patterns. This approach is commonly utilized in fields like psychology, education, marketing, and behavioral sciences to quantify behaviors, test hypotheses, and identify trends or relationships. Key aspects of quantitative analysis of behavior include: 1. **Measurement**: Collecting data through various means such as surveys, experiments, or observational studies. This data can include counts (e.g., frequency of a behavior), ratings (e.
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!
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.
