Analogical Models
Analogical models are a method of representing a phenomenon of the world, often called the "target system" by another, more understandable or analysable system. They are also called dynamical analogies. Two open systems have analog representations (see illustration) if they are black box isomorphic systems.

Anki
Anki (/ˈɒŋkiː/; Japanese: [aŋki]) is a free and open-source flashcard program using spaced repetition, a technique from cognitive science for fast and long-lasting memorization. "Anki" (暗記) is the Japanese word for "memorization". The SM-2 algorithm, created for SuperMemo in the late 1980s, forms the basis of the spaced repetition methods employed in the program. Anki's implementation of the algorithm has been modified to allow priorities on cards and to show flashcards in order of their urgency. The cards are presented using HTML and may include text, images, sounds, videos, and LaTeX equations. The decks of cards, along with the user's statistics, are stored in the open SQLite format.

Apache Wave
Apache Wave was a software framework for real-time collaborative editing online. Google originally developed it as Google Wave. It was announced at the Google I/O conference on May 27, 2009. Wave is a web-based computing platform and communications protocol designed to merge key features of communications media such as email, instant messaging, wikis, and social networking. Communications using the system can be synchronous or asynchronous. Software extensions provide contextual spelling and grammar checking, automated language translation and other features. Initially released only to developers, a preview release of Google Wave was extended to 100,000 users in September 2009, each allowed to invite additional users. Google accepted most requests submitted starting November 29, 2009, soon after the September extended release of the technical preview. On May 19, 2010, it was released to the general public. On August 4, 2010, Google announced the suspension of stand-alone Wave development and the intent of maintaining the web site at least for the remainder of the year, and on November 22, 2011, announced that existing Waves would become read-only in January 2012 and all Waves would be deleted in April 2012. Development was handed over to the Apache Software Foundation which started to develop a server-based product called Wave in a Box. It was retired in January 2018.

Aperiodic Frequency
Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. Frequency is measured in units of hertz (Hz) which is equal to one occurrence of a repeating event per second. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency. For example: if a newborn baby's heart beats at a frequency of 120 times a minute (2 hertz), its period, T, — the time interval between beats—is half a second (60 seconds divided by 120 beats). Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light.

Apple Network Server
The Apple Network Server (ANS) was a line of PowerPC-based server computers designed, manufactured and sold by Apple Computer, Inc. from February 1996 to April 1997. It was codenamed "Shiner" and originally consisted of two models, the Network Server 500/132 ("Shiner LE", i.e., "low-end") and the Network Server 700/150 ("Shiner HE", i.e., "high-end"), which got a companion model, the Network Server 700/200 (also "Shiner HE") with a faster CPU in November 1996. The machines were not a part of the Apple Macintosh line of computers; they were designed to run IBM's AIX operating system and their ROM specifically prevented booting the classic Mac OS. This makes them the last non-Macintosh desktop computers made by Apple to date. The 500/132, 700/150, and 97 sold in the U.S. market for $11,000, $15,000 and $19,000, respectively. Apple Network Servers are not to be confused with the Apple Workgroup Servers and the Macintosh Servers, which were Macintosh workstations that shipped with server software and used Mac OS; the sole exception, the Workgroup Server 95—a Quadra 950 with an added SCSI controller that shipped with A/UX—was also capable of running Mac OS. Apple did not have comparable server hardware in their product lineup again until the introduction of the Xserve in 2002. The product's short lifespan is attributed to significant financial troubles at Apple in early 1997. CEO Gil Amelio cancelled both Network Server and OpenDoc in the same meeting as it was determined that they were low priorities.
