  2. Time delay and integration - Wikipedia

    en.wikipedia.org/wiki/Time_Delay_and_Integration

    Time delay and integration. A time delay and integration or time delay integration (TDI) charge-coupled device (CCD) is an image sensor for capturing images of moving objects at low light levels. While using similar underlying CCD technology, in operation it contrasts with staring arrays and line scanned arrays. It works by synchronized ...

  3. Volkswagen Tiguan - Wikipedia

    en.wikipedia.org/wiki/Volkswagen_Tiguan

    The Volkswagen Tiguan ( German pronunciation: [ˈfɔlksˌvaːgŋ̍ ˈtiːɡu̯aːn]) is a series of cars produced by German manufacturer Volkswagen since 2007, sitting between the smaller T-Roc and the larger Touareg in the company's crossover SUV range. The first generation was based on the PQ46 platform, while the second generation, released ...

  4. Spaces of test functions and distributions - Wikipedia

    en.wikipedia.org/wiki/Spaces_of_test_functions...

    In mathematical analysis, the spaces of test functions and distributions are topological vector spaces (TVSs) that are used in the definition and application of distributions. Test functions are usually infinitely differentiable complex -valued (or sometimes real -valued) functions on a non-empty open subset that have compact support.

  5. Multiple-document interface - Wikipedia

    en.wikipedia.org/wiki/Multiple-document_interface

    Multiple-document interface. A multiple-document interface ( MDI) is a graphical user interface in which multiple windows reside under a single parent window. Such systems often allow child windows to embed other windows inside them as well, creating complex nested hierarchies. This contrasts with single-document interfaces ( SDI) where all ...

  6. Tissue Doppler echocardiography - Wikipedia

    en.wikipedia.org/wiki/Tissue_Doppler...

    The terms tissue Doppler imaging (TDI) and tissue velocity imaging (TVI) are usually synonymous with TDE because echocardiography is the main use of tissue Doppler. Like Doppler flow, tissue Doppler can be acquired both by spectral analysis ( spectral density estimation ) as pulsed Doppler [1] and by the autocorrelation technique as colour ...

  7. Transport Driver Interface - Wikipedia

    en.wikipedia.org/wiki/Transport_Driver_Interface

    The Transport Driver Interface or TDI is the protocol understood by the upper edge of the Transport layer of the Microsoft Windows kernel network stack. Transport Providers are implementations of network protocols such as TCP/IP, NetBIOS, and AppleTalk . When user-mode binaries are created by compiling and linking, an entity called a TDI client ...

  8. Boundary (topology) - Wikipedia

    en.wikipedia.org/wiki/Boundary_(topology)

    Boundary (topology) A set (in light blue) and its boundary (in dark blue). In topology and mathematics in general, the boundary of a subset S of a topological space X is the set of points in the closure of S not belonging to the interior of S. An element of the boundary of S is called a boundary point of S. The term boundary operation refers to ...

  9. TDI (engine) - Wikipedia

    en.wikipedia.org/wiki/TDI_(engine)

    TDI is the combination of two existing diesel engine technologies: Direct injection — where a fuel injector sprays the diesel fuel directly into the main combustion chambers. This causes a more complete combustion process than using a pre-combustion chamber (known as indirect injection ), which therefore increases the torque output and ...
