Implementations often have to use schemes such as phase-locked loops and self-calibration to reach the required timing accuracy.

Implementations of generics in languages such as Java and C # are formally based on the notion of parametricity, due to John C. Reynolds.

Implementations can be found via a number of web portals, such as EMBL FASTA and NCBI BLAST.

Software Implementations involve several professionals that are relatively new to the knowledge based economy such as Business Analysts, Technical Analysts, Solutions Architect, and Project Managers.

Implementations of connection-oriented protocols, such as the widely-used TCP protocol, generally watch for packet errors, losses, or delays ( see Quality of Service ) in order to adjust the transmit speed.

Implementations working with legacy data should be aware of such alternative representations for the numero sign when converting data.

Implementations of the API are available on many Unix-like POSIX-conformant operating systems such as FreeBSD, NetBSD, OpenBSD, GNU / Linux, Mac OS X and Solaris.

Implementations of algorithms such as AES and triple DES that are believed to be mathematically strong may be trivially breakable using power analysis attacks.

Implementations of the MTD ( f ) algorithm have been shown to be more efficient ( search fewer nodes ) in practice than other search algorithms ( e. g. Negascout ) in games such as chess, checkers, and Othello.

Implementations come from private companies or open source groups.

Implementations of the OMG specifications come from private companies or open source groups.

Implementations exist as proprietary software, provided as Message Queuing as a Service, as open source software, or be hardware-based.

Implementations of programming languages that offer interactive evaluation of source code ( using an interpreter or an incremental compiler ) present identifiers at runtime, sometimes even as first-class objects that can be freely manipulated and evaluated.

Implementations of Sallen – Key filters often use an operational amplifier configured as a voltage follower ; however, emitter or source followers are other common choices for the buffer amplifier.

Implementations of real time CORBA are widely used in control systems in ships and aircraft.

Implementations of the original 32-bit SPARC architecture were initially designed and used in Sun's Sun-4 workstation and server systems, replacing their earlier Sun-3 systems based on the Motorola 68000 family of processors.

He has written many journal and conference papers and two books: A Retargetable C Compiler: Design and Implementation ( ISBN 0-8053-1670-1, with Chris Fraser ), which describes lcc, a widely used compiler for Standard C, and C Interfaces and Implementations: Techniques for Creating Reusable Software ( ISBN 0-201-49841-3 ).

Implementations of SVG that uses the OpenVG API will be hardware accelerated on devices which have hardware acceleration of OpenVG.

Implementations of this sort of parallel / pipelined instruction system did not appear on modern commodity processors until the late 1990s, and vector instructions ( now known as SIMD ) until a few years later.

Implementations vary on how the interception of the packets is done — for example, some use virtual devices, others take a slice out of the firewall, etc.

Implementations may rely on external devices or be purely embedded, self-functioning devices.
