Gradian 1970-01-01
Gradian refers to a unit of angular measurement, used primarily in certain fields, including mathematics and engineering. It is also known as a "gon" or "grade." One gradian is defined as \(\frac{1}{400}\) of a full circle, which means that there are 400 gradians in a complete circle, compared to 360 degrees or \(2\pi\) radians.
Redenomination 1970-01-01
Redenomination is the process of adjusting the face value of a currency by changing the nominal value of banknotes and coins without altering their real value. This is often done by removing zeros from the currency, essentially converting the existing currency into a new unit of account. For example, in a redenomination, a currency that previously had a value of 1,000 units might be redenominated to a new unit of 1, effectively removing three zeros from the currency.
Square mil 1970-01-01
A square mil is a unit of area measurement that is equal to one millionth of a square inch. It is often used in fields such as engineering and electronics to specify very small areas, especially in relation to the cross-sectional area of conductors or other components. To be more precise, 1 square mil is defined as the area of a square with sides of one mil (0.001 inches) in length. In mathematical terms: 1 square mil = \( (0.

Defunct computer companies of the United States 1970-01-01
Defunct computer companies of the United States refer to businesses that were once involved in the development, manufacturing, or selling of computer hardware, software, or services but have since ceased operations. The reasons for their closure can vary, including financial difficulties, mergers and acquisitions, changes in technology, or shifts in market demand. Here are some notable defunct computer companies in the U.S.
Defunct networking companies 1970-01-01
Defunct networking companies are organizations that were once active in providing networking products, services, or technologies but have ceased operations. This could be due to a variety of reasons, including bankruptcy, poor management, market changes, competitive pressures, or technological obsolescence.
Grevelingendam 1970-01-01
Grevelingendam is an artificial dam in the Netherlands, specifically located in the province of Zeeland. It forms part of the Delta Works, a major series of construction projects designed to protect the Dutch coastline from flooding. The dam was built to close off the Grevelingen Lake from the North Sea, helping to manage water levels and serve as a barrier against storm surges.
Walter Feit 1970-01-01
Walter Feit is a notable mathematician recognized for his contributions to the field of group theory, particularly in relation to the theory of finite groups. He is well-known for the Feit-Thompson theorem, which proves that every finite group of odd order is solvable. This result was significant in the understanding of the structure of finite groups and has influenced much of modern algebra. Feit's work has garnered considerable respect within the mathematical community.
Émile Léonard Mathieu 1970-01-01
Émile Léonard Mathieu (1835–1890) was a French mathematician known for his contributions to various areas of mathematics, particularly in the field of differential equations and algebraic geometry. He is well-known for developing the theory of Mathieu functions, which are special functions that arise in problems of mathematical physics, particularly in the study of elliptic functions and various types of differential equations. Mathieu functions are often used in applications involving periodic potentials, such as in quantum mechanics and wave phenomena.
Michael Wheeler (philosopher) 1970-01-01
Michael Wheeler is a contemporary philosopher known for his work in philosophy of mind, cognitive science, and the philosophy of language. He has contributed to discussions on topics such as embodied cognition, externalism, and the nature of meaning and understanding. Wheeler often draws on insights from both philosophy and cognitive science to explore how our cognitive processes are influenced by our interactions with the world and the environments we inhabit.
Move-to-front transform 1970-01-01
The Move-to-Front (MTF) transform is a simple but effective data structure and algorithmic technique used primarily in various applications of data compression and information retrieval. The main idea behind the MTF transform is to reorder elements in a list based on their recent usage, which can improve efficiency in contexts where certain elements are accessed more frequently than others. ### How it Works: 1. **Initialization**: Start with an initial list of elements.
Μ-law algorithm 1970-01-01
The Μ-law algorithm, also known as Mu-law companding, is a method used primarily in telecommunications to optimize the dynamic range of audio signals for transmission. It compresses the amplitude of audio signals to reduce the bit rate required for digital transmission while still maintaining audio quality. This technique is especially common in North America and Japan for PCM (Pulse Code Modulation) systems. The Μ-law algorithm applies a compression curve to the amplitude levels of audio signals before digitization.
File comparison 1970-01-01
File comparison is the process of analyzing two or more files to identify differences and similarities between them. This can be done for various types of files, including text documents, code files, binary files, images, and more. The goal of file comparison is to determine how files differ in terms of content, structure, and any other relevant attributes.
Decimal prefixes 1970-01-01
Decimal prefixes are prefixes used in the metric system (and some other measurement systems) to denote multiples or fractions of units based on powers of ten. They simplify the naming of very large or very small quantities by allowing for a concise representation. Each decimal prefix corresponds to a specific power of ten.
Decimal time 1970-01-01
Decimal time is a timekeeping system that divides the day into decimal units rather than the traditional hours, minutes, and seconds. In a decimal time system, the day is typically divided into 10 decimal hours, each of which is further subdivided into 100 decimal minutes. Each decimal minute would then be divided into 100 decimal seconds. ### Key Features of Decimal Time: 1. **Decimal Hours**: A full day is divided into 10 decimal hours.
Two pence (British decimal coin) 1970-01-01
The two pence (2p) coin is a denomination of coin in the British decimal currency system. It was introduced on February 15, 1971, as part of the decimalization of the British currency, which transformed the previous system of pounds, shillings, and pence into a simpler system based solely on pounds and pence.

Compartmentalisation dam 1970-01-01
A compartmentalization dam is a type of dam designed to create isolated sections or compartments within a body of water, such as a lake or reservoir. The primary purpose of such a dam is to improve water management and control by partitioning the water into smaller, manageable areas. This can help in various ways, including: 1. **Flood Control**: By creating compartments, water levels can be more easily regulated, which can be beneficial in flood prevention and management.
Haringvlietdam 1970-01-01
The Haringvlietdam is a significant dam located in the Netherlands, part of the Zuiderzee Works, a major hydrological engineering project that aimed to manage the water levels and protect the inland areas from flooding. The dam stretches across the Haringvliet estuary, connecting the islands of Goeree-Overflakkee and Voorne-Putten to the mainland.
