Bit Manipulation Instruction Set
Bit manipulation instructions sets (BMI sets) are extensions to the x86 instruction set architecture for microprocessors from Intel and AMD. The purpose of these instruction sets is to improve the speed of bit manipulation. All the instructions in these sets are non-SIMD and operate only on general-purpose registers. There are two sets published by Intel: BMI (here referred to as BMI1) and BMI2; they were both introduced with the Haswell microarchitecture. Another two sets were published by AMD: ABM (Advanced Bit Manipulation, which is also a subset of SSE4a implemented by Intel as part of SSE4.2 and BMI1), and TBM (Trailing Bit Manipulation, an extension introduced with Piledriver-based processors as an extension to BMI1, but dropped again in Zen-based processors).

Nurses' Health Study
The Nurses' Health Study is a series of prospective studies that examine epidemiology and the long-term effects of nutrition, hormones, environment, and nurses' work-life on health and disease development. The studies have been among the largest investigations into risk factors for major chronic diseases ever conducted. The Nurses' Health Studies have led to many insights on health and well-being, including cancer prevention, cardiovascular disease, and type 2 diabetes. They have included clinicians, epidemiologists, and statisticians at the Channing Laboratory (of Brigham and Women's Hospital), Harvard Medical School, Harvard School of Public Health, and several Harvard-affiliated hospitals, including Brigham and Women's Hospital, Dana–Farber Cancer Institute, Children's Hospital Boston, and Beth Israel Deaconess Medical Center.

Ceph
Ceph (pronounced /ˈsɛf/) is an open-source software-defined storage platform that implements object storage on a single distributed computer cluster and provides 3-in-1 interfaces for object-, block- and file-level storage. Ceph aims primarily for completely distributed operation without a single point of failure, scalability to the exabyte level, and to be freely available. Since version 12, Ceph does not rely on other filesystems and can directly manage HDDs and SSDs with its own storage backend BlueStore and can completely self reliantly expose a POSIX filesystem. Ceph replicates data and makes it fault-tolerant, using commodity hardware and Ethernet IP and requiring no specific hardware support. The Ceph’s system offers disaster recovery and data redundancy through techniques such as replication, erasure coding, snapshots and storage cloning. As a result of its design, the system is both self-healing and self-managing, aiming to minimize administration time and other costs. In this way, administrators have a single, consolidated system that avoids silos and collects the storage within a common management framework. Ceph consolidates several storage use cases and improves resource utilization. It also lets an organization deploy servers where needed.

Domain Hack
A domain hack is a domain name that suggests a word, phrase, or name when concatenating two or more adjacent levels of that domain. For example, "bir.ds" and "examp.le", using the fictitious country-code domains .ds and .le, suggest the words birds and example respectively. In this context, the word hack denotes a clever trick (as in programming), not an exploit or break-in (as in security). Domain hacks offer the ability to produce short domain names. This makes them potentially valuable as redirectors, pastebins, base domains from which to delegate subdomains and URL shortening services.

Extreme Learning Machine
In the learning paradigms of artificial neural networks, classical algorithms such as back-propagation aim to approach the theories of biological learning through an iterative adjustment of all the hyper-parameters of the hidden layers for each sequence of data. Therefore, without looking at relearning, in actual problems, the tuning process could take days or months under the use of the available ordinary computers for generalization of the neural network over all of the selected samples. But, the fact that a microprocessor is faster than a brain by about twelve million times, denies that these algorithms are capable of responding to the thought of the human brain which takes less seconds to classify or restore new images or sensations. In 2004, ELM gave birth to new learning rules for artificial neural networks. ELM learning rules remove barriers between human biological thought and artificial neural networks by addressing the fact that: "the parameters of the hidden layer do not need to be adjusted, and the only element responsible for the "universal approximation and generalization are the output weights ". Consequently, ELM has been studied through several applications and extends to a multitude of paradigms such as the ensemble, the hybrid and the deep learning and achieved an excellent reputation. Therefore, The aim of this review will be introducing basic theories of ELM.

Gâteaux Derivative
In mathematics, the Gâteaux differential or Gâteaux derivative is a generalization of the concept of directional derivative in differential calculus. Named after René Gâteaux, a French mathematician who died young in World War I, it is defined for functions between locally convex topological vector spaces such as Banach spaces. Like the Fréchet derivative on a Banach space, the Gâteaux differential is often used to formalize the functional derivative commonly used in the calculus of variations and physics. Unlike other forms of derivatives, the Gâteaux differential of a function may be nonlinear. However, often the definition of the Gâteaux differential also requires that it be a continuous linear transformation. Some authors, such as (Tikhomirov 2001), draw a further distinction between the Gâteaux differential (which may be nonlinear) and the Gâteaux derivative (which they take to be linear). In most applications, continuous linearity follows from some more primitive condition which is natural to the particular setting, such as imposing complex differentiability in the context of infinite dimensional holomorphy or continuous differentiability in nonlinear analysis.

Forensic Geology
Forensic geology is the study of evidence relating to minerals, oil, petroleum, and other materials found in the Earth, used to answer questions raised by the legal system. In 1975, Ray Murray and fellow Rutgers University professor John Tedrow published Forensic Geology. The main use of forensic geology as it is applied today is regarding trace evidence. By examining the soil and sediment particules to be able to link a suspect to a particular crime or a particular scene. Other uses in this field of science can include theft, fraud, locating a gravesite etc. It requires the aid of many other disciplines of science such as medicine, biology, geography, engineering and many others. More recently, in 2008, Alastair Ruffell and Jennifer McKinley, both of Queen's University Belfast, published Geoforensics a book that focuses more on the use of geomorphology and geophysics for searches. In 2010, forensic soil scientist Lorna Dawson of the James Hutton Institute co-edited and contributed chapters to the textbook Criminal and Environmental Soil Forensics. In 2012, Elisa Bergslien, at SUNY Buffalo State, published a general textbook on the topic, An Introduction to Forensic Geoscience.

Differential Geometry of Curves
Differential geometry of curves is the branch of geometry that deals with smooth curves in the plane and in the Euclidean space by methods of differential and integral calculus. Starting in antiquity, many specific curves have been thoroughly investigated using the synthetic approach. Differential geometry takes another path: curves are represented in a parametrized form, and their geometric properties and various quantities associated with them, such as the curvature and the arc length, are expressed via derivatives and integrals using vector calculus. One of the most important tools used to analyze a curve is the Frenet frame, a moving frame that provides a coordinate system at each point of the curve that is "best adapted" to the curve near that point. The theory of curves is much simpler and narrower in scope than the theory of surfaces and its higher-dimensional generalizations, because a regular curve in a Euclidean space has no intrinsic geometry. Any regular curve may be parametrized by the arc length (the natural parametrization) and from the point of view of a theoretical point particle on the curve that does not know anything about the ambient space, all curves would appear the same. Different space curves are only distinguished by the way in which they bend and twist. Quantitatively, this is measured by the differential-geometric invariants called the curvature and the torsion of a curve. The fundamental theorem of curves asserts that the knowledge of these invariants completely determines the curve.

ICANN
The Internet Corporation for Assigned Names and Numbers (ICANN /ˈaɪkæn/ EYE-kan) is an American multistakeholder group and nonprofit organization responsible for coordinating the maintenance and procedures of several databases related to the namespaces and numerical spaces of the Internet, ensuring the network's stable and secure operation. ICANN performs the actual technical maintenance work of the Central Internet Address pools and DNS root zone registries pursuant to the Internet Assigned Numbers Authority (IANA) function contract. The contract regarding the IANA stewardship functions between ICANN and the National Telecommunications and Information Administration (NTIA) of the United States Department of Commerce ended on October 1, 2016, formally transitioning the functions to the global multistakeholder community. Much of its work has concerned the Internet's global Domain Name System (DNS), including policy development for internationalization of the DNS system, introduction of new generic top-level domains (TLDs), and the operation of root name servers. The numbering facilities ICANN manages include the Internet Protocol address spaces for IPv4 and IPv6, and assignment of address blocks to regional Internet registries. ICANN also maintains registries of Internet Protocol identifiers. ICANN's primary principles of operation have been described as helping preserve the operational stability of the Internet; to promote competition; to achieve broad representation of the global Internet community; and to develop policies appropriate to its mission through bottom-up, consensus-based processes. ICANN's creation was announced publicly on September 17, 1998, and it formally came into being on September 30, 1998, incorporated in the U.S. state of California. Originally headquartered in Marina del Rey in the same building as the University of Southern California's Information Sciences Institute (ISI), its offices are now in the Playa Vista neighborhood of Los Angeles in Facebook's old office.

ArchiCAD
ARCHICAD is an architectural BIM CAD software for Macintosh and Windows developed by the Hungarian company Graphisoft. ARCHICAD offers computer aided solutions for handling all common aspects of aesthetics and engineering during the whole design process of the built environment — buildings, interiors, urban areas, etc. Development of ARCHICAD started in 1982 for the Apple Lisa, the predecessor of the original Apple Macintosh. Following its launch in 1987, with Graphisoft's "Virtual Building" concept, ARCHICAD became regarded by some as the first implementation of BIM. ARCHICAD has been recognized as the first CAD product on a personal computer able to create both 2D and 3D geometry, as well as the first commercial BIM product for personal computers and considered "revolutionary" for the ability to store large amounts of information within the 3D model. Today, it has over 120,000 users.

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.

Fault-tolerant Computer System
Fault-tolerant computer systems are systems designed around the concepts of fault tolerance. In essence, they must be able to continue working to a level of satisfaction in the presence of errors or breakdowns. Fault tolerance is not just a property of individual machines; it may also characterise the rules by which they interact. For example, the Transmission Control Protocol (TCP) is designed to allow reliable two-way communication in a packet-switched network, even in the presence of communications links which are imperfect or overloaded. It does this by requiring the endpoints of the communication to expect packet loss, duplication, reordering and corruption, so that these conditions do not damage data integrity, and only reduce throughput by a proportional amount. Recovery from errors in fault-tolerant systems can be characterised as either 'roll-forward' or 'roll-back'. When the system detects that it has made an error, roll-forward recovery takes the system state at that time and corrects it, to be able to move forward. Roll-back recovery reverts the system state back to some earlier, correct version, for example using checkpointing, and moves forward from there. Roll-back recovery requires that the operations between the checkpoint and the detected erroneous state can be made idempotent. Some systems make use of both roll-forward and roll-back recovery for different errors or different parts of one error.

Graeco-Latin Square
In combinatorics, a Graeco-Latin square or Euler square or pair of orthogonal Latin squares of order n over two sets S and T, each consisting of n symbols, is an n×n arrangement of cells, each cell containing an ordered pair (s,t), where s is in S and t is in T, such that every row and every column contains each element of S and each element of T exactly once, and that no two cells contain the same ordered pair. The arrangement of the s-coordinates by themselves (which may be thought of as Latin characters) and of the t-coordinates (the Greek characters) each forms a Latin square. A Graeco-Latin square can therefore be decomposed into two "orthogonal" Latin squares. Orthogonality here means that every pair (s, t) from the Cartesian product S×T occurs exactly once.

Fractional Poisson Process
In probability theory, a fractional Poisson process is a stochastic process to model the long-memory dynamics of a stream of counts. The time interval between each pair of consecutive counts follows the non-exponential power-law distribution with parameter [math]\displaystyle{ \nu }[/math], which has physical dimension [math]\displaystyle{ [\nu ]=\sec ^{-\mu } }[/math], where [math]\displaystyle{ 0\lt \mu \leq 1 }[/math]. In other words, fractional Poisson process is non-Markov counting stochastic process that exhibits non-exponential distribution of interarrival times. The fractional Poisson process is a continuous-time process that can be thought of as natural generalization of the well-known Poisson process. Fractional Poisson probability distribution is a new member of discrete probability distributions. The fractional Poisson process, Fractional compound Poisson process and fractional Poisson probability distribution function have been invented, developed and encouraged for applications by Nick Laskin (2003) who coined the terms fractional Poisson process, Fractional compound Poisson process and fractional Poisson probability distribution function.
