Subjective Expected Relative Similarity (SERS)
Subjective expected relative similarity (SERS) is a normative and descriptive theory that predicts and explains cooperation levels in a family of games termed Similarity Sensitive Games (SSG), among them the well-known Prisoner's Dilemma game (PD). SERS was originally developed in order to (i) provide a new rational solution to the PD game and (ii) to predict human behavior in single-step PD games. It was further developed to account for: (i) repeated PD games, (ii) evolutionary perspectives and, as mentioned above, (iii) the SSG subgroup of 2x2 games. SERS predicts that individuals cooperate whenever their subjectively perceived similarity with their opponent exceeds a situational index derived from the game’s payoffs, termed the similarity threshold of the game. SERS proposes a solution to the rational paradox associated with the single step PD and provides accurate behavioral predictions. The theory was developed by Prof. Ilan Fischer at the University of Haifa.

Term (Logic)
In mathematical logic, a term denotes a mathematical object while a formula denotes a mathematical fact. In particular, terms appear as components of a formula. This is analogous to natural language, where a noun phrase refers to an object and a whole sentence refers to a fact. A first-order term is recursively constructed from constant symbols, variables and function symbols. An expression formed by applying a predicate symbol to an appropriate number of terms is called an atomic formula, which evaluates to true or false in bivalent logics, given an interpretation. For example, [math]\displaystyle{ (x+1)*(x+1) }[/math] is a term built from the constant 1, the variable x, and the binary function symbols [math]\displaystyle{ + }[/math] and [math]\displaystyle{ * }[/math]; it is part of the atomic formula [math]\displaystyle{ (x+1)*(x+1) \ge 0 }[/math] which evaluates to true for each real-numbered value of x. Besides in logic, terms play important roles in universal algebra, and rewriting systems.

Heuristic (Computer Science)
In mathematical optimization and computer science, heuristic (from Greek εὑρίσκω "I find, discover") is a technique designed for solving a problem more quickly when classic methods are too slow, or for finding an approximate solution when classic methods fail to find any exact solution. This is achieved by trading optimality, completeness, accuracy, or precision for speed. In a way, it can be considered a shortcut. A heuristic function, also simply called a heuristic, is a function that ranks alternatives in search algorithms at each branching step based on available information to decide which branch to follow. For example, it may approximate the exact solution.

Spectral Estimation of Multidimensional Signals
Power spectral estimation forms the basis for distinguishing and tracking signals in the presence of noise and extracting information from available data. One dimensional signals are expressed in terms of a single domain while multidimensional signals are represented in wave vector and frequency spectrum. Therefore, spectral estimation in the case of multidimensional signals gets a bit tricky.

Microsoft Double Space BIOS Parameter Block
DriveSpace (initially known as DoubleSpace) is a disk compression utility supplied with MS-DOS starting from version 6.0 in 1993 and ending in 2000 with the release of Windows Me. The purpose of DriveSpace is to increase the amount of data the user could store on disks by transparently compressing and decompressing data on-the-fly. It is primarily intended for use with hard drives, but use for floppy disks is also supported. This feature was removed in Windows XP and later.

Sustainable Adoption of E-Learning from the TAM Perspective
All TAM constructs significantly impact the BI of e-learning use. Additionally, the results showed that mentality acceptance substantially moderates the relationship between system trust and interaction, on the one hand, and PU and PEOU on the other. These findings suggest that educational institutions should focus on factors influencing teachers’ and students’ attitudes toward adopting and using e-learning services. Lack of internet connection, ICT skills, and technology capabilities are the main issues, and the main TAM constructs of all factors.

Cyber–Physical Systems Forensics
Cyber–Physical Systems (CPS) connect the physical world (systems, environments, and humans) with the cyber world (software, data, etc.) to intelligently enhance the operational environment they serve. CPS are distributed software and hardware components embedded in the physical world and possibly attached to humans. CPS are vulnerable to security risks, which requires incorporating appropriate forensics measures in the design and operations of these systems.

FO (Complexity)
In descriptive complexity, a branch of computational complexity, FO is a complexity class of structures that can be recognized by formulas of first-order logic, and also equals the complexity class AC0. Descriptive complexity uses the formalism of logic, but does not use several key notions associated with logic such as proof theory or axiomatization. Restricting predicates to be from a set X yields a smaller class FO[X]. For instance, FO[Similarly, extensions of first-order logic formed by the addition of operators give rise to other well-known complexity classes. This allows the complexity of some problems to be established without reference to algorithms.

Visi On
VisiCorp Visi On was a short-lived but influential graphical user interface-based operating environment program for IBM compatible personal computers running MS-DOS. Although Visi On was never popular, as it had steep minimum system requirements for its day, it was a major influence on the later development of Microsoft Windows.

Probabilistic Soft Logic
Probabilistic Soft Logic (PSL) is a statistical relational learning (SRL) framework for modeling probabilistic and relational domains. It is applicable to a variety of machine learning problems, such as collective classification, entity resolution, link prediction, and ontology alignment. PSL combines two tools: first-order logic, with its ability to succinctly represent complex phenomena, and probabilistic graphical models, which capture the uncertainty and incompleteness inherent in real-world knowledge. More specifically, PSL uses "soft" logic as its logical component and Markov random fields as its statistical model. PSL provides sophisticated inference techniques for finding the most likely answer (i.e. the maximum a posteriori (MAP) state). The "softening" of the logical formulas makes inference a polynomial time operation rather than an NP-hard operation.

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.

ThinkServer
The ThinkServer product line began with the TS100 from Lenovo. The server was developed under agreement with IBM, by which Lenovo would produce single-socket and dual-socket servers based on IBM's xSeries technology. An additional feature of the server design was a support package aimed at small businesses. The focus of this support package was to provide small businesses with software tools to ease the process of server management and reduce dependence on IT support. The tools developed for this support package included: Lenovo's ThinkServer naming conventions reflect whether the server is a tower server or a rack server. First letter "T" is used to indicate tower servers, while "R" is used for rack servers, and "S" is storage rack server. Similarly, secondary letter "S" indicates single socket, while "D" indicates dual-socket. The ThinkServer family has been discontinued in 2019, and the new family of Intel servers is named ThinkSystem.

MediaMax CD-3
MediaMax CD-3 is a software package created by SunnComm which was sold as a form of copy protection for compact discs. It was used by the record label RCA Records/BMG, and targets both Microsoft Windows and Mac OS X. Elected officials and computer security experts regard the software as a form of malware since its purpose is to intercept and inhibit normal computer operation without the user's authorization. MediaMax received media attention in late 2005 in fallout from the Sony XCP copy protection scandal. MediaMax is a second-generation system meant to address the problems of earlier copy-preventing schemes, where many types of playback devices had difficulty reading discs in normal use. MediaMax was first used on Anthony Hamilton's Comin' From Where I'm From in the United States ; the first US No. 1 CD to use it was Velvet Revolver's Contraband. (The European release of the Velvet Revolver album used Macrovision CDS-200 and the Japan ese is without copy protection.)
