Agent-Based Model in Biology
Agent-based models have many applications in biology, primarily due to the characteristics of the modeling method. Agent-based modeling is a rule-based, computational modeling methodology that focuses on rules and interactions among the individual components or the agents of the system. The goal of this modeling method is to generate populations of the system components of interest and simulate their interactions in a virtual world. Agent-based models start with rules for behavior and seek to reconstruct, through computational instantiation of those behavioral rules, the observed patterns of behavior.

Agrippa (A Book of the Dead)
Agrippa (A Book of the Dead) is a work of art created by science fiction novelist William Gibson, artist Dennis Ashbaugh and publisher Kevin Begos Jr. in 1992. The work consists of a 300-line semi-autobiographical electronic poem by Gibson, embedded in an artist's book by Ashbaugh. Gibson's text focused on the ethereal, human-owed nature of memories retained over the passage of time (the title referred to a Kodak photo album from which the text's memories are taken). Its principal notoriety arose from the fact that the poem, stored on a 3.5" floppy disk, was programmed to encrypt itself after a single use; similarly, the pages of the artist's book were treated with photosensitive chemicals, effecting the gradual fading of the words and images from the book's first exposure to light.

Albert Odyssey (Super Famicom Game)
Albert Odyssey (アルバートオデッセイ, Arubaato Odessei) is a tactical role-playing video game developed and published by Sunsoft and released for the Super Nintendo Entertainment System in Japan in March 1993. The game features strategy-based combat in addition to traditional role-playing game elements in two-dimensional environments. It is the first game in the Albert Odyssey series, and was followed by two sequels, Albert Odyssey 2: Jashin no Taidou in 1994, and Albert Odyssey in 1996. On June 12, 1996, Albert Odyssey was made available as a full game download on the Satellaview add-on as BS Albert Odyssey (BSアルバートオデッセイ, BS Arubaato Odessei), and the original Albert Odyssey was re-released for Satellaview in March 1998. Players assume the role of Albert, the young heroic swordsman who lives in a fantasy world filled with monsters and mythical creatures. While much of the world remains in relative peace following a great war many years before, a military faction led by the dark magician Globus has emerged to conquer the newly pacified nations and expand their empire. With the help of Albert's friends as well as hired mercenaries, the player must travel the world and eventually confront Golbus and his forces to prevent another large-scale conflict.

All-points Bulletin
An all-points bulletin (APB) is an electronic information broadcast sent from one sender to a group of recipients, to rapidly communicate an important message. The technology used to send this broadcast has varied throughout time, and includes Teletype, Radio, Computerised Bulletin Board Systems (CBBS), and Internet. The earliest known record of the all-points bulletin is when used by American police, which dates the term to 1947. Although, used in the field of policing at the time, the APB has had usage in fields such as politics, technology and science research. However, since the 21st Century, due to advances in technology, all-points bulletins have become significantly less common and are now only primarily used by police departments in countries such as America, Canada, Australia and the United Kingdom.

Alternating Direction Implicit Method
In numerical linear algebra, the Alternating Direction Implicit (ADI) method is an iterative method used to solve Sylvester matrix equations. It is a popular method for solving the large matrix equations that arise in systems theory and control, and can be formulated to construct solutions in a memory-efficient, factored form. It is also used to numerically solve parabolic and elliptic partial differential equations, and is a classic method used for modeling heat conduction and solving the diffusion equation in two or more dimensions. It is an example of an operator splitting method.

Altitude (Triangle)
In geometry, an altitude of a triangle is a line segment through a vertex and perpendicular to (i.e., forming a right angle with) a line containing the base (the side opposite the vertex). This line containing the opposite side is called the extended base of the altitude. The intersection of the extended base and the altitude is called the foot of the altitude. The length of the altitude, often simply called "the altitude", is the distance between the extended base and the vertex. The process of drawing the altitude from the vertex to the foot is known as dropping the altitude at that vertex. It is a special case of orthogonal projection. Altitudes can be used in the computation of the area of a triangle: one half of the product of an altitude's length and its base's length equals the triangle's area. Thus, the longest altitude is perpendicular to the shortest side of the triangle. The altitudes are also related to the sides of the triangle through the trigonometric functions. In an isosceles triangle (a triangle with two congruent sides), the altitude having the incongruent side as its base will have the midpoint of that side as its foot. Also the altitude having the incongruent side as its base will be the angle bisector of the vertex angle. It is common to mark the altitude with the letter h (as in height), often subscripted with the name of the side the altitude is drawn to. In a right triangle, the altitude drawn to the hypotenuse c divides the hypotenuse into two segments of lengths p and q. If we denote the length of the altitude by hc, we then have the relation For acute and right triangles the feet of the altitudes all fall on the triangle's sides (not extended). In an obtuse triangle (one with an obtuse angle), the foot of the altitude to the obtuse-angled vertex falls in the interior of the opposite side, but the feet of the altitudes to the acute-angled vertices fall on the opposite extended side, exterior to the triangle. This is illustrated in the adjacent diagram: in this obtuse triangle, an altitude dropped perpendicularly from the top vertex, which has an acute angle, intersects the extended horizontal side outside the triangle.

Alundra 2: A New Legend Begins
Alundra 2: A New Legend Begins (アランドラ2 魔進化の謎, Arandora 2 Ma Shinka no Nazo, Alundra 2: The Mystery of Magic Evolution) is an action role-playing game developed by Matrix Software for the Sony PlayStation. It was published by SCEI in Japan and Activision worldwide. Unlike its predecessor, Alundra, Alundra 2 features a 3D look which opens up a new world of puzzles. Also, despite its title, Alundra 2 is a standalone sequel, and has no ties with the original. It has a whole new story with a different set of characters, including the main character, Flint. Compared to the darker storyline of Alundra, Alundra 2 has a more light-hearted storyline.

AmigaOS
AmigaOS is a family of proprietary native operating systems of the Amiga and AmigaOne personal computers. It was developed first by Commodore International and introduced with the launch of the first Amiga, the Amiga 1000, in 1985. Early versions of AmigaOS required the Motorola 68000 series of 16-bit and 32-bit microprocessors. Later versions were developed by Haage & Partner (AmigaOS 3.5 and 3.9) and then Hyperion Entertainment (AmigaOS 4.0-4.1). A PowerPC microprocessor is required for the most recent release, AmigaOS 4. AmigaOS is a single-user operating system based on a preemptive multitasking kernel, called Exec. It includes an abstraction of the Amiga's hardware, a disk operating system called AmigaDOS, a windowing system API called Intuition, and a desktop environment and file manager called Workbench. The Amiga intellectual property is fragmented between Amiga Inc., Cloanto, and Hyperion Entertainment. The copyrights for works created up to 1993 are owned by Cloanto. In 2001, Amiga Inc. contracted AmigaOS 4 development to Hyperion Entertainment and, in 2009 they granted Hyperion an exclusive, perpetual, worldwide license to AmigaOS 3.1 in order to develop and market AmigaOS 4 and subsequent versions. On December 29, 2015, the AmigaOS 3.1 source code leaked to the web; this was confirmed by the licensee, Hyperion Entertainment.
