A non-renewable resource is a natural resource that cannot be reconstituted or regenerated at a sustainable rate relative to its consumption. These resources exist in finite quantities and can be depleted over time. The most common examples of non-renewable resources include: 1. **Fossil Fuels**: This category includes coal, oil, and natural gas, which are formed from the decomposed remains of ancient plants and animals over millions of years.
A rotation map is a function that describes the process of rotating points or vectors in a mathematical space, typically in two or three dimensions. In 2D space, for example, a rotation map takes a point represented by coordinates \((x, y)\) and rotates it by a certain angle \(\theta\) around the origin.
The Turán graph, denoted as \( T(n, r) \), is a specific type of graph used in extremal graph theory, which studies the conditions under which graphs contain certain subgraphs. The Turán graph is designed to be the largest \( K_{r+1} \)-free graph (a graph that does not contain a complete subgraph of \( r+1 \) vertices) with \( n \) vertices.
In graph theory, the **strength** of a graph typically refers to a specific concept related to the robustness or resilience of a network. However, the term can also have different meanings based on context. Here are a couple of interpretations: 1. **Graph Strength in Terms of Connectivity**: In some contexts, the strength of a graph can refer to its connectivity, specifically the minimum number of edges that need to be removed to disconnect the graph. This is often related to the concept of edge connectivity.
Amazon Neptune is a fully managed graph database service provided by Amazon Web Services (AWS). It is designed to support graph-based applications and can handle both property graph and RDF (Resource Description Framework) data models.
Blazegraph is a high-performance graph database that is designed to handle large-scale graph data and complex queries. It supports the RDF (Resource Description Framework) and SPARQL (SPARQL Protocol and RDF Query Language) standards, making it suitable for applications that involve semantic web technologies and linked data. Blazegraph is often used for applications such as knowledge graphs, social networks, and recommendation systems.
The Newick format is a way to represent tree structures, particularly phylogenetic trees, in a textual form. It uses a nested, parentheses-based notation that allows the representation of hierarchical relationships among various entities, such as species or genes, in a succinct manner. Each node in the tree can represent a taxon (e.g., a species) or a clade (a group of taxa), and the branches indicate evolutionary relationships.
"Shallow minor" is not a standard term widely recognized in music theory or other disciplines. However, the phrase could be interpreted in a few ways depending on the context in which it's used: 1. **Musical Context**: If we're discussing music, it might refer to a minor key (like A minor, B minor, etc.) that feels less intense or lacks depth, possibly due to its simplicity in composition or harmony.
The term "carving width" can refer to different contexts depending on the field, but it is most commonly associated with skiing and snowboarding. In this context, carving width typically refers to the width of a ski or snowboard that allows for effective carving turns. A wider carving width can offer greater stability and better edge control when making turns on hard-packed or icy conditions.
Clique-width is a graph parameter that provides a measure of the complexity of a graph in terms of its structure related to cliques (complete subgraphs). It plays a significant role in graph theory, particularly in the context of algorithm design and graph algorithms. A graph has clique-width \(k\) if it can be constructed using a specific process that involves the following operations: 1. **Creation of a new vertex (a single vertex graph)**.
In graph theory, the **metric dimension** of a graph is a concept that relates to the ability to uniquely identify the vertices of the graph based on their distances to a specific set of vertices known as "experimenters" or "measuring points.
The **clique-sum** is a graph operation used primarily in graph theory, particularly in the study of graph properties and constructions. This operation allows you to combine two graphs in a way that preserves some of their characteristics while introducing new structure. Here’s how the clique-sum operates: 1. **Graphs Involved**: You start with two graphs, say \(G_1\) and \(G_2\).
A medial graph is a concept used in the field of computational geometry, particularly in the areas of shape analysis and mesh processing. It represents the intrinsic structure of a geometric shape or surface. In essence, the medial graph captures the topological and geometrical characteristics of the shape's skeleton or centerlines. It is achieved through various methods, which typically involve identifying points that are equidistant from the boundary of the shape.
Graceful labeling is a concept in graph theory related to labeling the vertices of a graph in a specific way that satisfies certain criteria. A graph is said to be gracefully labeled if it can be assigned labels (usually integers) to its vertices such that the following conditions are met: 1. The labels assigned to the vertices are distinct integers, typically taken from the set {0, 1, 2, ...
The term "induced path" typically arises in various contexts, such as in mathematics, particularly in graph theory. In graph theory, an **induced path** refers to a specific kind of subgraph of a graph.
In the context of graph theory, a **minimum cut** refers to a specific type of partitioning of a graph that separates the vertices into two distinct subsets while minimizing the total weight of the edges that cross between these two subsets. ### Key Concepts: - **Graph**: A collection of vertices (nodes) connected by edges (links). - **Cut**: A cut in a graph is a way of dividing the graph's vertices into two disjoint subsets.
A configuration graph is a type of graph used to represent the states and transitions of a system, particularly in the context of distributed systems, robotics, or combinatorial problems. In general, configuration graphs help visualize how different configurations (or states) of a system can transition from one to another based on certain rules or actions.
A disjunctive graph is a concept often encountered in the fields of graph theory and computer science, particularly in relation to representation and analysis of logical expressions, automata, and certain types of optimization problems. However, the term "disjunctive graph" is not universally defined, and its meaning can vary based on the context.
The Ingredient-Flavor Network is a concept that explores the relationships between various food ingredients and their associated flavors. It is often represented as a network where ingredients serve as nodes and their flavor characteristics or pairings are represented as edges connecting these nodes. This network can help chefs, food scientists, and food enthusiasts to understand which ingredients complement each other based on shared flavor compounds or culinary traditions.
A Smith graph is a specific type of graph in graph theory. It is a 5-regular graph on 14 vertices, meaning that each vertex has exactly 5 edges connecting it to other vertices. The Smith graph has a unique property: it is both vertex-transitive and edge-transitive, which means that the structure looks the same from any vertex and from any edge. Certain characteristics of the Smith graph include: - It has 14 vertices and 35 edges.

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.
