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.

Bibliometrics is a statistical analysis method used to measure and evaluate various aspects of written publications, particularly academic and scholarly literature. It involves quantitative analysis of publications such as books, journal articles, conference papers, and more, to assess patterns, trends, and impacts of research outputs. Key aspects of bibliometrics include: 1. **Citation Analysis**: Examining how often publications are cited in other works to assess their influence and relevance within a field.

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.

Bi-hemispherical reflectance is a measure of how much light is reflected by a surface when illuminated from all directions over a hemisphere and then measured from another hemisphere. It is typically expressed as a ratio or percentage of the incident light that is reflected. In more detail: - **Bi-hemispherical** refers to the two hemispheres involved in the measurement: the hemisphere from which light is incident and the hemisphere from which the reflected light is measured.

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 \(10^9\).

The binary entropy function quantifies the uncertainty associated with a binary random variable, which can take on two possible outcomes (commonly denoted as 0 and 1). It is an important concept in information theory, providing a measure of the amount of information or the level of disorder in a binary system.

Binary Reed-Solomon encoding is a type of error-correcting code that is used to detect and correct errors in data storage and transmission. Reed-Solomon codes are based on algebraic constructs over finite fields, and the binary variant specifically deals with binary data (0s and 1s). ### Key Features of Binary Reed-Solomon Encoding: 1. **Error Correction**: Reed-Solomon codes can correct multiple bit errors in a block of data.

It is involved in providing services related to geographic information systems (GIS), satellite imagery analysis, and environmental monitoring. Geocarto International typically offers products and services that help organizations and governments make informed decisions based on spatial data. The company may focus on various applications, including land-use planning, natural resource management, disaster response, and environmental assessments.

The geocentric model is an astronomical theory that places the Earth at the center of the universe, with all other celestial bodies—such as the Sun, Moon, planets, and stars—orbiting around it. This model was widely accepted in ancient civilizations and was famously promoted by the Greek philosopher Claudius Ptolemy in the 2nd century AD in his work, the Almagest.

Press to Meco is a British alternative rock band known for their fusion of rock, progressive, and post-hardcore elements. Formed in 2013 in London, the band consists of members that include guitarist and vocalist Seb Barlow, bassist and vocalist Matt Fielder, and drummer and vocalist Luke Sanzone. They are recognized for their intricate guitar work, dynamic rhythms, and tight vocal harmonies that combine to create a distinctive sound.

Production equipment control refers to the processes and systems used to monitor, manage, and optimize the performance of equipment and machinery used in manufacturing and production environments. It encompasses various approaches to ensure that equipment operates efficiently, effectively, and reliably while maximizing productivity and minimizing downtime. Key aspects of production equipment control include: 1. **Monitoring and Data Collection**: Utilizing sensors and data acquisition systems to gather real-time information on equipment performance, such as speed, temperature, vibration, and operational status.

The 111th meridian west is a line of longitude that is 111 degrees west of the Prime Meridian, which runs through Greenwich, England. This meridian runs from the North Pole to the South Pole and passes through several regions in North America.

The Bishop–Gromov inequality is a fundamental result in Riemannian geometry that provides a comparison between the volume of geodesic balls in a Riemannian manifold and the volume of balls in a model space of constant curvature, specifically spherical or Euclidean spaces. The inequality is particularly useful in the context of manifolds with bounded sectional curvature.

Bismuth-209 is an isotope of the element bismuth, which has the chemical symbol Bi and an atomic number of 83. Bismuth-209 is notable because it is the most stable isotope of bismuth, with a half-life of about 1.9 × 10^19 years, making it extremely long-lived compared to other isotopes of bismuth.

Engine power refers to the rate at which an engine can perform work or generate energy. In the context of internal combustion engines, power is typically measured in horsepower (hp) or kilowatts (kW). It is an important indicator of an engine's performance and efficiency. The power output of an engine is influenced by factors such as: 1. **Engine Design**: The configuration, size, and technology used in the engine affect its power output.

Engine valves are critical mechanical components in internal combustion engines, responsible for regulating the flow of air and fuel into the combustion chamber and the exhaust gases out of it. There are typically two main types of engine valves: 1. **Intake Valves**: These valves open to allow the air-fuel mixture to enter the combustion chamber during the intake stroke of the engine cycle. They close during the compression and power strokes to ensure that the mixture is contained within the chamber for combustion.

Differential inclusion is a concept in mathematics, particularly in the area of differential equations and dynamical systems. It generalizes the notion of a differential equation by allowing the right-hand side to be a set-valued map rather than a single-valued function.

A **computational hardness assumption** is a principle or conjecture in cryptography and computer science that posits certain mathematical problems are inherently difficult to solve in a reasonable amount of time, even with the best known algorithms and the most powerful computers available. These assumptions are foundational for the security of various cryptographic systems and protocols.
