GarageBand includes a large selection of realistic, sampled instruments and software modeled synthesizers.

Early attempts to add the ability to real airplanes were not very successful ; the software was based on experiments conducted in flight simulators where jet engines are usually modeled as " perfect " devices with exactly the same thrust on each engine, a linear relationship between throttle setting and thrust, and instantaneous response to input.

Generally the bond and angle terms are modeled as harmonic potentials centered around equilibrium bond-length values derived from experiment or theoretical calculations of electronic structure performed with software which does ab-initio type calculations such as Gaussian.

* Responsibility-Driven Design, a software development methodology in which the system is modeled as a collection of objects that collaborate to fulfill the responsibilities.

Waves also offers a collection of modeled guitar amplifiers, speaker cabinets, and stomp effects called GTR, which includes software emulations of popular amps and cabs by Marshall, Fender, Mesa / Boogie, Vox, and others.

Images in this category were modeled, rendered, or otherwise generated using the Blender 3D modelling software.

Despite the fact that UML in this way can be used to model an integrated software system it has been argued that the reality of business can be modeled with a software modeling language.

More recently the Plan has been modeled on computers using CAD software.

So they decided to designed a TRS-80 and CP / M software compatible computer system, which ( following the lead of Apple Computer ) they decided to name after a " typical Dutch flower ".

Soon after, BBS software was being written for all of the major home computer systems of the late 1970s era-the Apple II, Atari, Commodore and TRS-80 being some of the most popular.

NetAlert, the software made available free of charge by the Australian government, was allegedly cracked by a 16 year old student, Tom Wood, less than a week after its release in August 2007.

This was a way to allow PDP-8 software to be run even after the official end-of-life announcement for the Digital PDP-8 product line.

This included the use of ROM for library software that could be run much faster than the same code in the normal core memory, due to the latter ’ s need to be written immediately after being read.

Dhrystone remains in use 20 years after it was designed by Weicker, a longer life than most software.

Once a decision was made to use a particular vendor's software to enter a design, the customer was ever after constrained to use no other software.

In January 2005, more than two years after the software was originally planned for completion, the FBI officially abandoned the project.

Uses of the word in the decades after the 1960s are more concentrated in computer culture, such as a 1984 appearance in InfoWorld: " There isn't any software!

However, because an IDE is a complicated piece of software by its very nature, this higher productivity only occurs after a lengthy learning process.

An early visual programming system, Max, was modelled after analog synthesizer design and has been used to develop real-time music performance software since the 1980s.

On 5 December 2005, the Federal Court of Australia ceased downloads of Kazaa in Australia after Sharman Networks failed to modify their software by the December 5 deadline.

It was named after the amateur radio callsign of Phil Karn, who first wrote the software for a CP / M system and then ported it to DOS on the IBM PC.

Jones & Associates ), brought on board ten young programmers to write the software after winning a contract to develop a word processor for the Connecticut Mutual Life Insurance company.

They must also be restored after that software is finished.

This was primarily due to the increased usage of Microsoft's Internet Explorer web browser software, and partly because the Netscape Corporation ( later purchased by AOL ) did not sustain Netscape Navigator's technical innovation after the late 1990s.

* Persistence: Like any database, it must have the ability to insure the data's survival between sessions, after shutdown and subsequent restart of the server software / hardware.

In software development, this approach is often known as the waterfall model, i. e., one series of tasks after another in linear sequence.

Recamming is also used with speedruns in order to make the experience more movie-like, with arbitrary control of camera angles, editing, and sound that can be applied with editing software after the runs are first recorded.

However, after that the shareware model began to degrade as the term was used by commercial startups offering ( sometimes substandard ) commercial software and labeling non-functional or limited demo versions ( termed crippleware ) as shareware.
