Compact convergence is a concept in the field of functional analysis and topology that describes a type of convergence of a sequence of functions. More precisely, it is a form of convergence that refers to the behavior of functions defined on compact spaces. Let \(X\) be a compact topological space, and let \( \{ f_n \} \) be a sequence of continuous functions from \(X\) to \(\mathbb{R}\) (or \(\mathbb{C}\)).
A compact tension specimen, often referred to as a "CT specimen," is a standardized test specimen used in fracture mechanics to assess the crack propagation behavior of materials, particularly to determine their toughness. The compact tension test is designed to create a controlled stress state around a pre-existing crack, allowing for the evaluation of the material's resistance to crack growth under different loading conditions.
A compartmentalization dam is a type of dam designed to create isolated sections or compartments within a body of water, such as a lake or reservoir. The primary purpose of such a dam is to improve water management and control by partitioning the water into smaller, manageable areas. This can help in various ways, including: 1. **Flood Control**: By creating compartments, water levels can be more easily regulated, which can be beneficial in flood prevention and management.
The Quadratic Bottleneck Assignment Problem (QBAP) is an optimization problem that seeks to assign a set of agents to a set of tasks in such a way that the maximum cost associated with any assignment is minimized. It can be considered a generalization of the classic assignment problem, which focuses on minimizing the total cost of assignments without regard to the maximum individual costs. ### Problem Definition - **Agents**: A set of \( n \) agents (or workers).
The Markstein number is a dimensionless quantity used in the study of combustion, particularly in the analysis of flame stability and propagation. It is defined as the ratio of the perturbation velocity of a combustion front to the rate of change of the flame's position. The Markstein number provides insight into the stability of a flame; specifically, it helps in assessing how changes in flame speed can affect the behavior of the flame in a given environment.
The term "composite cross population" typically refers to a breeding strategy used in animal or plant genetics, particularly in agricultural contexts. It involves crossing multiple populations or breeds to create a new population that combines desirable traits from each of the original populations. Here’s a more detailed breakdown: 1. **Composite**: This indicates that the resulting population is made up of individuals from various parent populations. The goal is to introduce genetic diversity and robustness within the new population.
During World War II, the German Army employed a variety of cryptographic systems to secure their communications. One of the most notable systems was the use of the Enigma machine. Here are some key points about German Army cryptographic systems during this period: 1. **Enigma Machine**: - The Enigma was an electro-mechanical rotor cipher machine used by the German military. It was designed to create a polyalphabetic substitution cipher.
"German plasma physicists" refers to scientists and researchers in Germany who specialize in the study of plasma physics. Plasma physics is the branch of physics that deals with the properties and behavior of plasma, which is a state of matter consisting of charged particles, including ions and electrons. This area of study has various applications, including in fusion energy research, astrophysics, space physics, and industrial processes.
"Computing and society" refers to the interdisciplinary study and analysis of the interactions between computing technologies and societal structures, values, and practices. This field explores how advancements in computing (such as software development, data analytics, artificial intelligence, and cybersecurity) influence various aspects of life, including social relationships, economy, culture, ethics, and governance.
Lipschitz maps (or Lipschitz continuous functions) are a class of functions that satisfy a specific type of continuity condition, known as the Lipschitz condition.
Conceptual Dependency Theory is a model developed in the 1970s by Roger Schank as part of his work in artificial intelligence and natural language processing. The theory aims to represent the meaning of sentences in a structured and consistent way by focusing on the underlying concepts rather than the specific words used.
Conditional proof is a method used in logic and mathematics to establish the validity of an implication (a conditional statement of the form "If P, then Q"). The technique involves assuming the antecedent (the part before the "then") of the conditional statement and then deriving the consequent (the part after the "then") from that assumption.
The Conference on Implementation and Application of Automata (CIAA) is an academic conference that focuses on the theory, implementation, and applications of automata and formal languages. Automata are mathematical models of computation that are used to design and analyze algorithms and systems in computer science.
Conflict-free coloring is a concept in combinatorial geometry and graph theory that relates to assigning colors to elements (often points in a geometric space or vertices in a graph) in such a way that certain criteria regarding "conflicts" are satisfied. The principal idea is to ensure that in any given region or subset, at least one point or vertex retains a unique color that is not shared by any other point or vertex within that specific subset.
Summability methods are mathematical techniques used to assign values to certain divergent series or to improve the convergence of convergent series. These methods are crucial in various areas of mathematics, including analysis, number theory, and numerical mathematics. The idea behind summability is to provide a way to assign a meaningful value or limit to series that do not converge in the traditional sense. Several types of summability methods exist, each with its own specific approach and areas of application.
A conjecture is an educated guess or a proposition that is believed to be true based on preliminary evidence or reasoning, but has yet to be proven or substantiated. In mathematics, for example, a conjecture is a statement that appears to be true because of observed patterns or numerical evidence, but it requires a formal proof to be accepted as a theorem. Conjectures play a crucial role in the development of mathematical theories, as they often lead to further research and exploration.

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
