Camera resectioning, often referred to as camera pose estimation or camera calibration, is a computer vision technique used to determine the orientation and position of a camera in relation to a scene. It involves estimating the parameters that describe the camera's intrinsic (internal characteristics of the camera, such as focal length and lens distortion) and extrinsic (position and orientation in space) properties.

Cameroonian mathematicians are individuals from Cameroon or of Cameroonian descent who engage in the field of mathematics either as researchers, educators, or practitioners. The country has a growing community of mathematicians who contribute to various areas of mathematical research and education, including pure and applied mathematics, statistics, and mathematical modeling. The development of mathematics in Cameroon has been supported by universities, research institutions, and organizations that promote STEM (science, technology, engineering, and mathematics) education.

A cam follower is a type of mechanical device used in conjunction with a cam to convert rotary motion into linear motion. It consists of a follower that tracks the contour of a cam profile, which is usually designed to provide specific motion characteristics. Cam followers are commonly found in various applications, including engines, manufacturing machinery, and automation systems. **Key Features of Cam Followers:** 1. **Components:** A cam follower typically has a spherical or cylindrical roller that makes contact with the cam surface.

Canadian anti-nuclear weapons activists are individuals and groups in Canada who advocate against the proliferation and use of nuclear weapons. Their efforts are motivated by concerns over the potential catastrophic consequences of nuclear warfare, environmental impacts, and ethical considerations regarding the possession and potential use of such weapons. These activists typically engage in a variety of activities, which can include: 1. **Public Education and Awareness**: They work to raise awareness about the dangers of nuclear weapons through campaigns, educational events, and community outreach.

George Boole (1815–1864) was an English mathematician, logician, and philosopher, best known for his work in the fields of algebra and logic. He is regarded as one of the founders of symbolic logic and made significant contributions to mathematics, particularly in the area of what is now called Boolean algebra. Boolean algebra is a branch of algebra that deals with binary values (true and false, often represented as 1 and 0).

"Canadian physical chemists" refers to scientists in Canada who specialize in physical chemistry, a branch of chemistry that deals with the study of how matter behaves on a molecular and atomic level, incorporating concepts from physics to explain chemical phenomena. Physical chemists often explore the principles behind chemical reactions, the properties of molecules, and the thermodynamics of chemical systems, among other topics. In Canada, physical chemists can be found in various academic institutions, research organizations, and industries.

Flood Modeller is a software application designed for flood risk management and hydrological modelling. It is primarily used by engineers, hydrologists, and environmental scientists to simulate flood events, analyze flood risk, and assess the effectiveness of flood management strategies. The software provides tools for: 1. **Hydrodynamic Modelling**: It allows users to create detailed models of river and floodplain systems to simulate water flow and inundation patterns during flood events.

George B. Pegram was an American physicist known for his contributions to the fields of nuclear and particle physics. He served as a professor and researcher in several prestigious institutions, including Columbia University. In addition to his research work, he was noted for his leadership roles in various scientific organizations and played a significant part in the development of the field of nuclear science. If you meant something else by "George B.

Protein–ligand docking is a computational technique used to predict the preferred orientation and binding affinity of a small molecule (the ligand) when it interacts with a protein (typically a receptor or enzyme). This method is essential in fields such as drug discovery, where understanding how a potential therapeutic compound interacts with a biological target is crucial for developing effective medications. ### Key Concepts in Protein–Ligand Docking: 1. **Protein Structure**: The three-dimensional structure of the protein is essential for docking.

Cannelure refers to a groove or groove-like feature, often seen on the surface of bullets or casings in firearms and ammunition. These grooves are typically applied to the bullet to serve specific purposes, such as: 1. **Crimping**: The cannelure allows for a crimping process to hold the bullet securely in place within the cartridge case. This helps prevent movement of the bullet under recoil or during handling and ensures consistent performance.

In physics, motion refers to the change in position of an object over time. It is a fundamental concept that can be described in terms of parameters such as displacement, distance, velocity, acceleration, and time. Here are some key aspects of motion: 1. **Displacement**: This is a vector quantity that refers to the change in position of an object. It has both magnitude and direction.

Cantor's theorem is a fundamental result in set theory proposed by the mathematician Georg Cantor. It states that for any set \( S \), the set of all subsets of \( S \), known as the power set of \( S \) (denoted as \( \mathcal{P}(S) \)), has a strictly greater cardinality (size) than the set \( S \) itself.

Capping inversion is a phenomenon that can occur in various contexts, such as in finance or project management, but it is most commonly associated with the concept of capitalization in investment and financial contexts. However, without more specific context, it’s challenging to provide a precise definition. 1. **Finance and Investment Context**: In finance, "capping" often refers to limiting the maximum potential of an investment or the growth of financial returns.

George David Birkhoff (1884–1944) was an American mathematician known for his significant contributions to various areas of mathematics, particularly in dynamical systems, topology, and the field of mathematical aesthetics. He is perhaps best known for Birkhoff's theorem in the context of general relativity and for his work in ergodic theory.

Cardinality is a mathematical concept that refers to the number of elements in a set or the size of a set. It is used to describe the quantity of items in both finite and infinite sets. 1. **Finite Sets**: For finite sets, cardinality is simply the count of distinct elements.

Carl Charlier was a Swedish astronomer, best known for his contributions to celestial mechanics and astrophysics in the early 20th century. He is particularly recognized for developing statistical methods for analyzing astronomical data. One of his notable works involved the analysis of stellar distribution in the Milky Way and contributions to the study of star clusters and nebulae.
