Attributional calculus 1970-01-01
Attributional calculus, often referred to in the context of reasoning and inference systems, is a formal framework used to model and manipulate complex relationships between events, entities, or concepts. Although not a widely recognized term in standard mathematical literature, the concept can generally relate to reasoning about causation and the attribution of causes and effects within a logical framework.
Dependence logic 1970-01-01
Dependence logic is a type of logic that extends classical first-order logic by incorporating the concept of dependence between variables. It was introduced by the logician Johan van Benthem in the early 2000s. The key idea is to formalize the notion of dependency between variables, allowing for the expression of statements about how the value of one variable affects or is determined by the values of others.
Discourse representation theory 1970-01-01
Discourse Representation Theory (DRT) is a framework in semantics and computational linguistics that seeks to represent the meaning of sentences in a way that accounts for context and the relationships between entities mentioned in discourse. Developed primarily by Hans Kamp in the 1980s, DRT focuses on how information is structured in language, particularly in relation to an unfolding narrative or conversation.
Dynamic semantics 1970-01-01
Dynamic semantics is a theoretical approach to understanding the meaning of linguistic expressions that focuses on how context and discourse evolve over time during communication. Unlike static semantics, which views meaning as fixed and derived from the lexical and grammatical properties of expressions alone, dynamic semantics considers how the meaning of sentences can change based on the discourse context and how they interact with previous statements.
Epsilon calculus 1970-01-01
Epsilon calculus, also known as epsilon substitution or epsilon calculus of constructions, is a formal system and a framework within mathematical logic and particularly in the foundation of mathematics. It extends first-order logic by incorporating a special operator, usually denoted by the Greek letter epsilon (ε), which is used to express the idea of "the witness" or "the choice" in logical statements. The central idea in epsilon calculus is to allow assertions involving existence to be represented in a more constructive way.
Formal ethics 1970-01-01
Formal ethics, often referred to as deontological ethics, is a branch of ethical theory that emphasizes the importance of rules, duties, and obligations in determining what is moral. It is characterized by the idea that certain actions are inherently right or wrong, regardless of their consequences. This approach to ethics is concerned with the principles that govern moral behavior and often involves the formulation of universal laws or rules that apply to all individuals.
General set theory 1970-01-01
General set theory is a branch of mathematical logic that studies sets, which are fundamental objects used to define and understand collections of objects and their relationships. It serves as the foundation for much of modern mathematics, providing the language and framework for discussing and manipulating collections of objects. ### Key Concepts in General Set Theory: 1. **Sets and Elements**: A set is a well-defined collection of distinct objects, called elements or members.
Kripke–Platek set theory 1970-01-01
Kripke–Platek set theory (KP) is a foundational system of set theory that was introduced by Saul Kripke and Richard Platek in the context of investigating the foundations of mathematics, particularly in relation to computability and constructive mathematics. KP is primarily notable for its focus on the notion of set comprehension while placing restrictions on the kinds of sets that can be formed.
Many-sorted logic 1970-01-01
Many-sorted logic is a type of logic that extends classical first-order logic by allowing variables to take values from multiple distinct types or sorts. In a many-sorted logic system, the domain of discourse is divided into different sorts, each representing a different type of object. This contrasts with standard first-order logic, where there is typically a single domain of discourse.
S (set theory) 1970-01-01
In set theory, "S" is often used as a symbol to represent a set, although it doesn't have a specific meaning on its own. The context in which "S" is used typically defines what set it refers to. For example, "S" might represent the set of all natural numbers, the set of all real numbers, or any other collection of objects defined by certain properties or criteria.
Semiset 1970-01-01
The term "semiset" can refer to different concepts depending on the context. However, it is not a widely established term in common usage. Here are a couple of interpretations that could apply: 1. **Mathematics/Set Theory**: In the context of set theory, a "semiset" could be thought of as a collection of elements that could have certain properties of a set but does not fulfill all the criteria to be considered a standard set.
MKS system of units 1970-01-01
The MKS system of units is a system of measurement that uses three fundamental physical quantities: meter (m), kilogram (kg), and second (s). It is a part of the International System of Units (SI), which is the modern standard for measuring physical quantities. The MKS system serves as a basis for deriving other units used in various fields of science and engineering.
N-body units 1970-01-01
N-body units refer to a system of natural units used in astrophysics and computational astrophysics, specifically in simulations of gravitational systems involving multiple bodies, or N bodies. In these simulations, it is often useful to express quantities in a way that simplifies calculations and highlights essential physical relationships. The N-body units are typically derived from choosing characteristic scales for length, mass, and time based on the system being studied.
Norwegian units of measurement 1970-01-01
Plan for Establishing Uniformity in the Coinage, Weights, and Measures of the United States 1970-01-01
The Plan for Establishing Uniformity in the Coinage, Weights, and Measures of the United States refers to a series of proposals and actions aimed at standardizing the systems of currency, mass, and volume in the United States. This initiative was particularly influenced by the need for consistency across various states and the desire to simplify trade and commerce.
Pyeong 1970-01-01
"Pyeong" (평) is a traditional Korean unit of area measurement commonly used in South Korea. One pyeong is approximately equal to 3.3 square meters or about 35.6 square feet. It is frequently used to describe the size of living spaces, such as apartments or rooms. For example, when discussing real estate, the size of a property may be listed in pyeong. The term can also come up in discussions about land use and construction.
Romanian units of measurement 1970-01-01
Romania, like most countries, uses the International System of Units (SI), which is based on the metric system. Here are some common units of measurement used in Romania: 1. **Length**: - Meter (m) - Centimeter (cm) - Millimeter (mm) - Kilometer (km) 2. **Mass**: - Kilogram (kg) - Gram (g) - Milligram (mg) 3.
Swedish units of measurement 1970-01-01
Sweden primarily uses the metric system for measurements, which is standard in most countries around the world except for a few like the United States. Here are some of the common units of measurement used in Sweden: 1. **Length**: - Meter (m) - Centimeter (cm) - Millimeter (mm) - Kilometer (km) 2.
System of units of measurement 1970-01-01
A system of units of measurement is a standardized set of units used to quantify physical quantities, such as length, mass, time, temperature, and more. These systems provide a framework for measuring and expressing various physical properties and phenomena, ensuring consistency and clarity in communication across different fields, such as science, engineering, and everyday life.
Metalog distribution 1970-01-01
The Metalog distribution is a flexible family of probability distributions that can be used to model various types of data. It was introduced by T. H. D. U. Chen et al. in a 2012 paper as a way to provide a more versatile alternative to traditional distributions like the normal, lognormal, or gamma distributions.
