Vissim

Vissim may refer to:

  • VisSim, a visual block diagram language for model based simulation and embedded development. It is developed by Visual Solutions in Massachusetts.
  • PTV VISSIM, a microscopic simulation program for multi-modal traffic flow modeling. It is developed by PTV AG in Germany.
  • PTV VISSIM

    PTV Vissim is a microscopic multi-modal traffic flow simulation software package developed by PTV Planung Transport Verkehr AG in Karlsruhe, Germany. The name is derived from "Verkehr In Städten - SIMulationsmodell" (German for "Traffic in cities - simulation model"). PTV Vissim was first developed in 1992 and is today a global market leader.

    PTV Vissim is part of the PTV Vision Traffic Suite which also includes PTV Visum (traffic analysis and forecasting) and PTV Vistro (signal optimisation and traffic impact).

    Microscopic simulation

    "Microscopic simulation", sometimes called microsimulation, means that each entity (car, train, person) of reality that is to be simulated is simulated individually, i.e. it is represented by a corresponding entity in the simulation, thereby considering all relevant properties. The same holds for the interactions between the entities. The opposite would be a "macroscopic simulation", in which the description of reality is shifted from individuals to "averaged" variables like flow and density. The corresponding product from the same manufacturer is called VISUM.

    VisSim

    VisSim is a visual block diagram language for simulation of dynamical systems and model based design of embedded systems. It is developed by Visual Solutions of Westford, Massachusetts. It uses a graphical data flow paradigm to implement dynamic systems based on differential equations. Version 8 adds interactive UML OMG 2 compliant state chart graphs that are placed in VisSim diagrams. This allows easy modeling of state based systems like startup sequencing of process plants or serial protocol decoding.

    Applications

    VisSim is widely used in control system design and digital signal processing for multidomain simulation and design. It includes blocks for arithmetic, Boolean, and transcendental functions, as well as digital filters, transfer functions, numerical integration and interactive plotting. The most commonly modeled systems are aeronautical, biological/medical, digital power, electric motor, electrical, hydraulic, mechanical, process, thermal/HVAC and econometric.

    Academic use

    Accredited educational institutions are allowed to site license VisSim v3.0 at no cost. The latest versions of VisSim and add-ons are also available to students and academic institutions at greatly reduced pricing.

    In The Wind

    by: Foesum

    [Featuring Bo Roc]
    Yeah this is Bo Roc from the Dove Shack
    G Funk representing baby
    And I'm chillin with my homeboys Foesum and the Twinz
    (And I'm in the wind)
    This is how we gonna set it off for all my folks
    T Dubb
    I see my games recognized who despise get a glimpse
    I'm tryin to seperate myself from these playa hatin simps
    rollin down the backstreets with my peeps it's on again
    LBC and cuz I'm off in the wind
    establish myself to keep my chips on stacks
    so face the facts as I bring it to you just like that
    don't play me so locc, listen to the Dubb and chill
    just loungin wit the homies so I'm keepin it real
    now, what about those days when I was strugglin for my pay
    when times got rough and some of the homeys went astray
    but never the less I keep the facts and regards
    stayin true to myself as I'm pullin your card
    now break me off cuz I'm settin it off to get my props
    still rollin with the fo and shakin those that jock
    So peep game as I'm comin through, ooh
    cuz what goes around comes around I thought you knew
    (Chorus) Bo-Roc
    Oh I'm in the wind
    I set it off now look around
    cuz what goes around, comes around and round
    it's calling to be falling but I'm balling
    cuz it's all in my game, in my game
    M&M-
    Verse deuce
    Lemme get loose
    With your attention as I hit you from a whole nother direction
    Perfection, is how it started and I'm finished
    cuz even though you hit the top (top)
    someday you'll drop (drop), and then diminish (gone)
    it's just a struggle living day to day
    I count my ends sippin gin in the wind as I fade away
    but some be actin like they made in the shade
    cuz they paid but really and truly should've stayed
    real with yo mind in the right frame
    it's cool to floss like the boss but maintain the same game
    what you be thinkin it's no tellin
    but I stay funkish on my ends
    roll with my friends and continue bellin
    it's just the way I see things as a G and,
    Your lost in the zone
    cuz you flossin on your own
    I ain't the type to break another homey down
    But what goes around comes around
    you shoulda listened to the sound
    (Chorus)
    DJ Glaze-
    Yo, I'm bellin in the names and lemme run it to ya
    and spit a little game to the homeys on how it's comin to ya
    so step aside lemme slide through
    while I get to peepin thangs I'm comin from my view
    cuz anytime you caught up in the struggle you see it all,
    lose some of your homeys around the way and others don't even call
    (damn)
    But I ain't trippin it ain't like that
    if you show me love I show you homey love right back
    cuz I ain't never been the type that'll ever forget about ya
    get to spreadin rumors that other some people said about ya
    cuz in the past we had fun with homeys kickin it deep
    but now I'm dippin with them G's from the F to the O to the E
    and as for the females you know how they trip
    anytime they see you makin chips they quick to get on ya tip
    but I ain't goin out, you shoulda stayed down
    and watch who you clown
    cuz what goes around comes around
