What is Propeller theory?

In theoretical physics, there are many theories with supersymmetry which also have internal gauge symmetries. Supersymmetric gauge theory generalizes this notion.

Mixture theory is used to model multiphase systems using the principles of continuum mechanics generalised to several interpenetrable continua. The basic assumption is that, at any instant of time, all...

Punctuated equilibrium in social theory is a conceptual framework for understanding the process of change in complex social systems. The approach studies the evolution of policy change, including the evolution...

In mathematics, specifically in homotopy theory and category theory, coherency is the standard that equalities or diagrams must satisfy when they hold "up to homotopy" or "up to isomorphism". The...

The IEEE International Symposium on Information Theory is the flagship meeting of the IEEE Information Theory Society. Every year and during the course of a week, researchers in the field...

The Iran Workshop on Communication and Information Theory is an international academic workshop that is held annually in one of the Iranian University campuses. The purpose of this workshop...

Unlike a standard one-piece boat or aircraft propeller, a modular propeller is made up of using a number of replaceable parts, typically: Modular propellers may be fitted to aircraft as...

In category theory, a branch of mathematics, a pullback is the limit of a diagram consisting of two morphisms f : X → Z and g : Y → Z with a common codomain. The pullback is...

In ring theory, a branch of abstract algebra, an idempotent element or simply idempotent of a ring is an element a such that a = a. That is, the element...

In mathematical logic, and more specifically in model theory, an infinite structure which is totally ordered by < is called an o-minimal structure if and only if every definable subset...
