Two Dimensional Window Design
Windowing is a process where an index limited sequence has its maximum energy concentrated in a finite frequency interval. This can be extended to an N-dimension where the N-D window has the limited support and maximum concentration of energy in a separable or non-separable N-D passband. The design of an N-dimensional window particularly a 2-D window finds applications in various fields such as spectral estimation of multidimensional signals, design of circularly symmetric and quadrantally symmetric non-recursive 2D filters, design of optimal convolution functions, image enhancement so as to reduce the effects of data-dependent processing artifacts, optical apodization and antenna array design.

Twister
Twister is an experimental peer-to-peer microblogging program. It is decentralized, meaning that no one is able to shut it down as there is no single point to attack. The system uses end-to-end encryption to safeguard communications. It is based on both BitTorrent and Bitcoin-like protocols and has been likened to a distributed version of Twitter.

Tuxedo
Tuxedo (Transactions for Unix, Extended for Distributed Operations) is a middleware platform used to manage distributed transaction processing in distributed computing environments. Tuxedo is a transaction processing system or transaction-oriented middleware, or enterprise application server for a variety of systems and programming languages. Developed by AT&T in the 1980s, it became a software product of Oracle Corporation in 2008 when they acquired BEA Systems. Tuxedo is now part of the Oracle Fusion Middleware.

TUTOR (Programming Language)
TUTOR (also known as PLATO Author Language) is a programming language developed for use on the PLATO system at the University of Illinois at Urbana-Champaign around 1965. TUTOR was initially designed by Paul Tenczar for use in computer assisted instruction (CAI) and computer managed instruction (CMI) (in computer programs called "lessons") and has many features for that purpose. For example, TUTOR has powerful answer-parsing and answer-judging commands, graphics, and features to simplify handling student records and statistics by instructors. TUTOR's flexibility, in combination with PLATO's computational power (running on what was considered a supercomputer in 1972), also made it suitable for the creation of many non-educational lessons—that is, games—including flight simulators, war games, dungeon style multiplayer role-playing games, card games, word games, and medical lesson games such as Bugs and Drugs (BND).

Turn (Geometry)
A turn is a unit of plane angle measurement equal to 2π radians, 360 degrees or 400 gradians. A turn is also referred to as a cycle (abbreviated cyc), revolution (abbreviated rev), complete rotation (abbreviated rot) or full circle. Subdivisions of a turn include half turns, quarter turns, centiturns, milliturns, points, etc.

Turing Reduction
In computability theory, a Turing reduction from a problem A to a problem B, is a reduction which solves A, assuming the solution to B is already known (Rogers 1967, Soare 1987). It can be understood as an algorithm that could be used to solve A if it had available to it a subroutine for solving B. More formally, a Turing reduction is a function computable by an oracle machine with an oracle for B. Turing reductions can be applied to both decision problems and function problems. If a Turing reduction of A to B exists then every algorithm for B can be used to produce an algorithm for A, by inserting the algorithm for B at each place where the oracle machine computing A queries the oracle for B. However, because the oracle machine may query the oracle a large number of times, the resulting algorithm may require more time asymptotically than either the algorithm for B or the oracle machine computing A, and may require as much space as both together. The first formal definition of relative computability, then called relative reducibility, was given by Alan Turing in 1939 in terms of oracle machines. Later in 1943 and 1952 Stephen Kleene defined an equivalent concept in terms of recursive functions. In 1944 Emil Post used the term "Turing reducibility" to refer to the concept. A polynomial-time Turing reduction is known as a Cook reduction, after Stephen Cook.

TurboGears
TurboGears is a Python web application framework consisting of several WSGI components such as WebOb, SQLAlchemy, Genshi and Repoze. TurboGears is designed around the model–view–controller (MVC) architecture, much like Struts or Ruby on Rails, designed to make rapid web application development in Python easier and more maintainable. Since version 2.3 the framework has also been providing a "minimal mode" which enables it to act as a microframework for usage in environments where the whole stack is not required nor wanted.

Turbo
Turbo (formerly Spoon and Xenocode) is a set of software products and services developed by the Code Systems Corporation for application virtualization, portable application creation, and digital distribution. Code Systems Corporation is an American corporation headquartered in Seattle, Washington (state) , and is best known for its Turbo products that include Browser Sandbox, Turbo Studio, TurboServer, and Turbo. Kenji Obata founded Code Systems Corporation in 2006 and introduced Turbo’s precursor, Xenocode. Xenocode was an early application virtualization engine for the Windows platform. Obata serves as the CEO of the corporation, which had become commonly known as Spoon since a rebranding in 2010. Turbo’s tools package conventional software applications for Microsoft Windows in a portable application format that can be delivered via a single executable or streamed over the web. Files and settings automatically synchronize across devices via Turbo’s patented virtualization technology which allows access to local files and printers from web-based applications.

Tudor Rose
The Tudor rose (sometimes called the Union rose) is the traditional floral heraldic emblem of England and takes its name and origins from the House of Tudor, which united the House of Lancaster and the House of York. The Tudor rose consists of five white inner petals, representing the House of York, and five red outer petals to represent the House of Lancaster.

TScript
TScript is an object-oriented embeddable scripting language for C++ that supports hierarchical transient typed variables (TVariable). Its main design criterion is to create a scripting language that can interface with C++, transforming data and returning the result. This enables C++ applications to change their functionality after installation.
