Cone beam reconstruction refers to a technique used in imaging, particularly in medical fields like dentistry, radiology, and orthopedics. It involves acquiring three-dimensional (3D) images of an object or a region of interest, typically the human anatomy, using a cone-shaped beam of X-rays. This method has become increasingly popular due to its ability to provide high-resolution images in a relatively short time, while utilizing lower doses of radiation compared to traditional computed tomography (CT) scans.
The X-ray transform is a mathematical operation used in various fields, particularly in imaging and tomography, to reconstruct images from projection data. The concept is analogous to how X-ray machines work in medical imaging, where X-rays penetrate through the body and produce projections of the internal structures onto a detector.

Svetozar Kurepa was a notable Croatian mathematician, recognized for his contributions to functional analysis, set theory, and topology. He was born on October 7, 1926, in the former Kingdom of Yugoslavia and passed away on May 19, 2019. Kurepa's work is particularly important in the areas of infinite-dimensional spaces and the foundations of mathematics.
Dušanka Đokić is a notable figure, but no specific widely recognized entity or individual by that name is readily known based on commonly available information as of my last knowledge update in October 2021. There may be specific context, such as cultural or local relevance, that would help clarify who she is.
Ratko Janev is a Serbian physicist known for his work in atomic and plasma physics, including contributions to the understanding of atomic processes in fusion plasmas. He has published extensively in these fields and is recognized for his research on the interaction of charged particles with matter, which is relevant to both plasma physics and fusion energy research.
The Airy zeta function is a mathematical function that is related to the solutions of the Airy differential equation. The Airy functions, denoted as \( \text{Ai}(x) \) and \( \text{Bi}(x) \), are special functions that arise in various physical problems, particularly in quantum mechanics and wave phenomena, where they describe the behavior of a particle in a linear potential.
The Hardy–Littlewood zeta-function conjectures refer to a set of conjectures proposed by mathematicians G.H. Hardy and J.E. Littlewood regarding the distribution of prime numbers and, more broadly, the properties of number-theoretic functions.
The Langlands Program is a vast and influential set of conjectures and theories in the fields of number theory and representation theory, proposed by the mathematician Robert Langlands in the late 1960s. It seeks to establish deep connections between different areas of mathematics, notably between: 1. **Number Theory**: The study of integers and their properties. 2. **Representation Theory**: The study of how algebraic structures, like groups, can be represented through linear transformations of vector spaces.
The Local Langlands Conjecture is a significant and deep area of research in number theory and representation theory, particularly concerning the connections between Galois groups and representations of reductive algebraic groups over p-adic fields.
The Motivic L-function is a concept from modern algebraic geometry and number theory, particularly within the framework of motives. Motivic L-functions provide a unifying approach to understanding various types of L-functions, which appear in number theory, algebraic geometry, and representation theory.
Unicode equivalence refers to the concept that different sequences of Unicode code points may represent the same abstract character or string of characters. This is particularly important in text processing, searching, and comparisons, as it ensures that semantically similar text is treated as equivalent even if their underlying representations differ. In Unicode, there are generally two types of equivalence to consider: 1. **Normalization Forms**: Unicode defines several normalization forms that convert text into a standard representation.
A deterministic automaton, specifically a deterministic finite automaton (DFA), is a theoretical model of computation used in computer science to recognize patterns and define regular languages. Here are the key characteristics of a DFA: 1. **Finite States**: A DFA consists of a finite number of states, including one start state and one or more accept (or final) states.
The term "Chronographer" typically refers to a device or instrument used for measuring time intervals, closely related to a chronograph. A chronograph is a specific type of watch or clock that combines the functions of a stopwatch with a standard timekeeping function. It features one or more sub-dials to record specific time intervals and may have pushers to start, stop, and reset the measurement.
"The Self-Sufficient-ish Bible" is a guidebook typically aimed at those interested in self-sufficiency, sustainability, and living a more eco-friendly lifestyle. Authored by authors or experts in the field of self-sufficiency, the book offers practical advice and tips on various topics such as gardening, food preservation, foraging, composting, and DIY projects.
"TechWriter" can refer to several different concepts, primarily in the realm of technology and documentation. Here are a few possible interpretations: 1. **Technical Writer**: This is the most common interpretation. A technical writer is a professional who creates documents that communicate complex information about products, processes, or services to specific audiences. They often draft user manuals, guides, FAQs, and online help documentation for software and hardware.
In music, a "part" refers to a specific line or portion of a piece that is designated for a particular instrument or voice within a larger ensemble or composition. Each part typically corresponds to the music that a musician plays or sings, and it is often written as a separate score or line within a full orchestral or choral score. For example: - In an orchestra, there are different parts for violins, cellos, trumpets, etc.
A security pattern is a general reusable solution to a recurring security problem within a given context. These patterns provide established strategies, methods, or templates to address various security challenges in software design and architecture. By using security patterns, developers and architects can create systems that are more resilient to attacks and vulnerabilities. Security patterns can be categorized into various types, including: 1. **Authentication Patterns**: These address how users prove their identity. Examples include password-based authentication, multi-factor authentication, and biometric authentication.

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.
