A **Knapsack auction** is a variation of auction mechanisms that introduces elements from the well-known "knapsack problem" from combinatorial optimization. In a classic knapsack problem, the goal is to select a subset of items, each with a given weight and value, such that the total weight is within a specified limit (the capacity of the knapsack) and the total value is maximized.
In topology, the complement of a knot refers to the space that remains when the knot is removed from the three-dimensional space.
Knowledge Interchange Format (KIF) is a formal language used for the representation and interchange of knowledge among disparate computer systems. It was designed to facilitate the sharing of information and the integration of knowledge-based systems. KIF can represent complex structures and relationships, making it useful for various artificial intelligence applications, including knowledge representation, reasoning, and the semantic web.
Knowledge services refer to a range of activities and techniques aimed at managing, optimizing, and leveraging knowledge within an organization. These services encompass the processes through which knowledge is created, captured, shared, and utilized to improve decision-making, enhance innovation, and drive organizational effectiveness. Knowledge services typically include: 1. **Knowledge Management (KM)**: The practice of collecting, organizing, sharing, and analyzing an organization’s knowledge assets to enhance learning and performance.
The Kolakoski sequence is an infinite sequence of integers that is defined recursively. It is notable because it is self-generating and consists only of the integers 1 and 2. The sequence begins with 1 and is constructed by reading the lengths of groups of 1s and 2s as specified by the terms of the sequence itself. The construction process goes as follows: 1. Start with the initial term: \( 1 \).
The Kolmogorov–Zurbenko (KZ) filter, named after mathematicians Andrey Kolmogorov and Vladimir Zurbenko, is a statistical method used for smoothing time series data. It is particularly useful for the analysis of time series that may contain noise or outliers, and it is a powerful tool in many fields, including meteorology, environmental science, and economics.
A hyperbolic link in mathematics, particularly in the study of topology and knot theory, refers to a certain type of link (a collection of knots that may be intertwined) that has a hyperbolic structure. This means that the complement of the link in three-dimensional space can be equipped with a Riemannian metric of constant negative curvature.
Hyperbolic space is a type of non-Euclidean geometry that generalizes the concepts of traditional Euclidean geometry to a space with a constant negative curvature. In hyperbolic geometry, the parallel postulate of Euclidean geometry—specifically, that through a point not on a given line, there is exactly one line parallel to the given line—does not hold. Instead, through a point not on a given line, there are infinitely many lines that do not intersect the given line.
A hypercomplex manifold is a specific type of manifold that is equipped with a structure allowing it to have a rich geometric and algebraic framework. More precisely, a hypercomplex manifold is a differentiable manifold \( M \) endowed with an almost complex structure associated with three complex structures \( I, J, K \) that satisfy certain quaternionic relations.
Hypercube internetwork topology is a network structure that is used to interconnect multiple nodes (computers or processors) in a specific geometric arrangement. It is based on the mathematical concept of a hypercube, which generalizes the idea of a cube to more than three dimensions. ### Key Characteristics of Hypercube Topology: 1. **Dimensional Structure**: - A hypercube in n dimensions, also called an n-cube, has \(2^n\) nodes.
A **hyperfinite field** typically refers to a concept in the realm of mathematical logic and model theory, particularly in the study of non-standard analysis and structures. It is often related to the idea of constructing fields that have properties akin to finite fields but with an infinite nature.
The hypergeometric identity refers to various identities involving hypergeometric series, which are a class of power series defined by the generalized hypergeometric function.
As of my last knowledge update in October 2023, the term "Hyperphoton" does not refer to a widely recognized concept in physics, technology, or any other established field. It may be a conceptual or speculative term used in a particular context or a creative work, or it might be a recent development or term that has emerged since my last update.
Hypsicles is a figure from ancient Greek mathematics, particularly recognized for his contributions to geometry and number theory. He lived around the 2nd century BCE and is best known for his work on the properties of polygons and numbers. One of his notable contributions is in the study of the relationships between numbers and shapes, including his work on the relationships between regular polygons and their areas.
Iain M. Johnstone is a prominent statistician renowned for his contributions to the fields of statistics and machine learning, particularly in the areas of high-dimensional data analysis, non-parametric statistics, and statistical decision theory. He has published extensively in various academic journals and is known for his work on topics like model selection, estimation methods, and theoretical underpinnings of statistical techniques.
Ian G. Macdonald is an American physician and researcher known for his work in the field of cardiology, particularly regarding heart disease and cardiovascular health. He has contributed to various studies and advancements in the understanding of heart conditions and treatments. If you're referring to a specific Ian G.
Ibn al-Adami, often referred to in literary contexts, is a fictional or legendary figure frequently mentioned in allegorical narratives and literature. The name might not directly correspond to a widely recognized historical or contemporary figure, but it can be reminiscent of characters from various cultural stories. In certain contexts, it can also refer to "Ibn al-Adami" as a term related to "the son of Adam," drawing upon Biblical or Qur'anic references.
Idealization in the philosophy of science refers to the process of simplifying complex phenomena by making assumptions or creating theoretical models that exclude certain variables or factors. This allows scientists to focus on essential features of the phenomenon under study while ignoring less relevant details. Idealizations are often employed to make theories more comprehensible, computationally manageable, or to derive predictions that can be tested against empirical data.

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.
