Experimental rockets are spacecraft designed to test new technologies and concepts related to rocketry and spaceflight. Unlike operational rockets that are used for commercial launches or government missions, experimental rockets often focus on research and development. They serve various purposes, including: 1. **Technology Demonstration**: Testing new propulsion systems, materials, and design concepts aimed at improving rocket performance, safety, or reliability.

Ezra Pound (1885–1972) was an American poet, critic, and one of the most influential figures in modernist literature. He is best known for his role in the development of modern poetry and for his contributions to various literary forms, including imagism and Vorticism. Pound's works often emphasized clarity, precision, and the use of concrete imagery, breaking away from traditional poetic conventions.

A paroemion is a rhetorical device characterized by the repetition of a word or words in close proximity, often used to create emphasis or to enhance the rhythmic quality of a phrase or text. It typically highlights a particular idea or theme by repeating specific terms, making the message more memorable. This technique can be found in various forms of literature, including poetry, speeches, and prose, thereby reinforcing key concepts or emotions within the work.

Faces was a British rock band that emerged in the late 1960s, evolving from the earlier group Small Faces. Formed in 1969, the band consisted of members Rod Stewart (vocals), Ron Wood (guitar), Ian McLagan (keyboards), and Kenney Jones (drums), with the original bassist, Ronnie Lane, remaining in the group. Faces are known for their energetic live performances and a sound that blends rock, blues, and folk elements.

Collective classification refers to a set of techniques in machine learning and data mining that focus on the prediction of labels for multiple interrelated instances simultaneously, rather than individually. This approach is particularly useful in domains where instances have dependencies or relationships with each other, such as social networks, citation networks, and biological networks. In traditional classification, each instance is treated independently, and the classification model predicts the label for each instance based solely on its features.

Collision response refers to the methods and processes involved in determining how objects interact after a collision occurs in a physical simulation, such as in computer graphics, video games, or physics engines. When two or more objects collide, their velocities, positions, and sometimes even their shapes can change based on the nature of the collision. The primary goals of collision response are to accurately simulate the physical effects of collisions and to ensure that objects behave in a realistic manner according to the laws of physics.

Combinational logic refers to a type of digital logic circuit whose output is a pure function of the present state of its inputs. In other words, the output at any given time depends only on the combination of inputs at that same time, without any memory of past inputs. This is in contrast to sequential logic, where the output depends on both the current inputs and the state of the system (which may be influenced by past inputs).

Combination weapons refer to firearms that integrate multiple functionalities into a single weapon platform. These can include various combinations of firearms and other tools or features, such as: 1. **Firearm and Tools**: A weapon that combines a firearm with other tools, like a knife, flashlight, or even a taser. For instance, a firearm that has a built-in flashlight or laser sight.

The Commercial Advertisement Loudness Mitigation (CALM) Act is a United States law that was enacted to address the issue of excessively loud television commercials. Signed into law in December 2010, the act requires that television commercials have the same average volume as the programs they accompany. The CALM Act mandates the use of specific technical standards set by the Federal Communications Commission (FCC), which ensure that the volume of commercials is consistent with the volume of the shows.

The term "commercial code" in the context of communications generally refers to a set of guidelines, standards, or protocols that govern the conduct of businesses in their communications with stakeholders, including customers, suppliers, and regulatory bodies. These codes can encompass various areas such as advertising, customer service, privacy, and digital communication.

Commercial fusion refers to the development and implementation of nuclear fusion technology for practical, large-scale energy generation and other industrial applications. Unlike traditional nuclear fission, which splits heavy atomic nuclei to release energy, nuclear fusion involves the merging of light atomic nuclei, typically isotopes of hydrogen like deuterium and tritium, to form heavier nuclei, releasing vast amounts of energy in the process.

Common Algebraic Specification Language (CASL) is a formal specification language designed for the specification of algebraic data types and their associated operations. It is aimed at providing a framework for the precise definition of software systems and their behaviors using mathematical concepts. ### Key Features of CASL: 1. **Algebraic Data Types**: CASL allows the definition of data types using constructors, enabling the specification of complex data structures in a clear and concise manner.

Azriel Rosenfeld is known as a pioneering figure in the field of computer science, particularly in image processing and computer vision. He has made significant contributions to the development of algorithms and methodologies for image analysis. Rosenfeld co-authored several influential publications and books in the areas of image processing and pattern recognition. Rosenfeld is particularly recognized for his work on the mathematical and algorithmic foundations that underlie various techniques in image processing, including edge detection, segmentation, and morphological operations.

The Communications & Information Services Corps (CIS Corps) is a branch within military organizations, specifically in the context of the Canadian Armed Forces. This corps is typically responsible for managing and providing communication and information technology (IT) services. Key functions may include: 1. **Communication Systems**: The CIS Corps operates and maintains various communication systems, including radio, satellite, and internet communications, ensuring that units can communicate effectively.

SPHARM-PDM stands for "Spherical Harmonic Parameterization and Shape Descriptor Model." It is a computational technique often used in the fields of medical imaging and computer graphics for analyzing and representing three-dimensional shapes, particularly biological structures. The approach uses spherical harmonics, a mathematical tool employed to represent functions on the sphere, to provide a compact and efficient way to describe the geometry of complex shapes.

The Community of Inquiry (CoI) framework is a conceptual model developed to guide the design and assessment of online and blended educational experiences. It emphasizes the importance of three interdependent elements that contribute to effective learning in a community setting: social presence, cognitive presence, and teaching presence. 1. **Social Presence**: This element refers to the ability of participants to project themselves socially and emotionally in the online environment, allowing for a sense of belonging and interpersonal connection.

Companding is a signal processing technique that combines compression and expansion of signal amplitudes to optimize the dynamic range of audio or communication signals. The term "companding" is derived from "compressing" and "expanding." ### How Companding Works: 1. **Compression**: During the transmission or recording of a signal (like audio), the dynamic range is reduced. This means that quieter sounds are amplified, and louder sounds are attenuated.

Composite reflectivity is a measure used in meteorology, particularly in radar meteorology, to represent the maximum reflectivity values observed in a volume of the atmosphere at different altitudes. It is derived from weather radar data and provides an overview of precipitation intensity within a vertical column of the atmosphere.

Companion diagnostics are medical devices or tests that provide information essential for the safe and effective use of a corresponding therapeutic product, often a drug. These diagnostics help identify patients who are most likely to benefit from a specific treatment or who may be at increased risk for serious side effects due to their unique biological characteristics.

A **quadratically closed field** is a type of field in which every non-constant polynomial of degree two has a root.
