Redundancy (linguistics)
In linguistics, a redundancy is information that is expressed more than once. Examples of redundancies include multiple agreement features in morphology, multiple features distinguishing phonemes in phonology, or the use of multiple words to express a single idea in rhetoric. For instance, while the previous sentence is grammatically correct and uses words appropriately, its rhetorical structure contains unnecessary repetitions and could be revised as, "Linguistic redundancy is regarded as having more than one: agreement feature in morphology; phoneme distinguishing feature in phonology; or word to express a single idea in rhetoric." as a clear, concise, and redundancy-free way to express the original concept. Grammar Redundancy may occur at any level of grammar. Because of agreement – a requirement in many languages that the form of different words in a phrase or clause correspond with one another – the same semantic information may be expressed several times. In the Sp ...

Data Redundancy
In computer main memory, auxiliary storage and computer buses, data redundancy is the existence of data that is additional to the actual data and permits correction of errors in stored or transmitted data. The additional data can simply be a complete copy of the actual data (a type of repetition code), or only select pieces of data that allow detection of errors and reconstruction of lost or damaged data up to a certain level. For example, by including computed check bits, ECC memory is capable of detecting and correcting single-bit errors within each memory word, while RAID 1 combines two hard disk drives (HDDs) into a logical storage unit that allows stored data to survive a complete failure of one drive. Data redundancy can also be used as a measure against silent data corruption; for example, file systems such as Btrfs and ZFS use data and metadata checksumming in combination with copies of stored data to detect silent data corruption and repair its effects.

Logic Redundancy
Logic is the study of correct reasoning. It includes both formal and informal logic. Formal logic is the study of deductively valid inferences or logical truths. It examines how conclusions follow from premises based on the structure of arguments alone, independent of their topic and content. Informal logic is associated with informal fallacies, critical thinking, and argumentation theory. Informal logic examines arguments expressed in natural language whereas formal logic uses formal language. When used as a countable noun, the term "a logic" refers to a specific logical formal system that articulates a proof system. Logic plays a central role in many fields, such as philosophy, mathematics, computer science, and linguistics. Logic studies arguments, which consist of a set of premises that leads to a conclusion. An example is the argument from the premises "it's Sunday" and "if it's Sunday then I don't have to work" leading to the conclusion "I don't have to work." Premi ...

Redundancy (engineering)
In engineering and systems theory, redundancy is the intentional duplication of critical components or functions of a system with the goal of increasing reliability of the system, usually in the form of a backup or fail-safe, or to improve actual system performance, such as in the case of GNSS receivers, or multi-threaded computer processing. In many safety-critical systems, such as fly-by-wire and hydraulic systems in aircraft, some parts of the control system may be triplicated, which is formally termed triple modular redundancy (TMR). An error in one component may then be out-voted by the other two. In a triply redundant system, the system has three sub components, all three of which must fail before the system fails. Since each one rarely fails, and the sub components are designed to preclude common failure modes (which can then be modelled as independent failure), the probability of all three failing is calculated to be extraordinarily small; it is often outweighed ...

Total Quality Management
Total quality management (TQM) is an organization-wide effort to "install and make a permanent climate where employees continuously improve their ability to provide on-demand products and services that customers will find of particular value." ''Total'' emphasizes that departments in addition to production (for example sales and marketing, accounting and finance, engineering and design) are obligated to improve their operations; ''management'' emphasizes that executives are obligated to actively manage quality through funding, training, staffing, and goal setting. While there is no widely agreed-upon approach, TQM efforts typically draw heavily on the previously developed tools and techniques of quality control. TQM received widespread attention during the late 1980s and early 1990s before being overshadowed by ISO 9000, Lean manufacturing, and Six Sigma. History In the late 1970s and early 1980s, the developed countries of North America and Western Europe suffered economic ...

User Interface
In the industrial design field of human–computer interaction, a user interface (UI) is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, while the machine simultaneously feeds back information that aids the operators' decision-making process. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls and Unit operation, process controls. The design considerations applicable when creating user interfaces are related to, or involve such disciplines as, ergonomics and psychology. Generally, the goal of user interface design is to produce a user interface that makes it easy, efficient, and enjoyable (user-friendly) to operate a machine in the way which produces the desired result (i.e. maximum usability). This generally means that the operator needs to provide mi ...

Codon Redundancy
Degeneracy or redundancy of codons is the redundancy of the genetic code, exhibited as the multiplicity of three-base pair codon combinations that specify an amino acid. The degeneracy of the genetic code is what accounts for the existence of synonymous mutations. Background Degeneracy of the genetic code was identified by Lagerkvist. For instance, codons GAA and GAG both specify glutamic acid and exhibit redundancy; but, neither specifies any other amino acid and thus are not ambiguous or demonstrate no ambiguity. The codons encoding one amino acid may differ in any of their three positions; however, more often than not, this difference is in the second or third position. For instance, the amino acid glutamic acid is specified by GAA and GAG codons (difference in the third position); the amino acid leucine is specified by UUA, UUG, CUU, CUC, CUA, CUG codons (difference in the first or third position); and the amino acid serine is specified by UCA, UCG, UCC, UCU, AGU, AGC (differe ...

Cytokine Redundancy
Cytokine redundancy is a term in immunology referring to the phenomenon in which, and the ability of, multiple cytokines to exert similar actions. This phenomenon is largely due to multiple cytokines utilizing common receptor subunits and common intracellular cell signalling molecules/ pathways. For instance, a pair of redundant cytokines are interleukin 4 and interleukin 13. Cytokine redundancy is associated with the term ''cytokine pleiotropy Pleiotropy () is a condition in which a single gene or genetic variant influences multiple phenotypic traits. A gene that has such multiple effects is referred to as a ''pleiotropic gene''. Mutations in pleiotropic genes can impact several trait ...'', which refers to the ability of cytokines to exert multiple actions. References Immunology {{immunology-stub ...

Gene Redundancy
Gene redundancy is the existence of multiple genes in the genome of an organism that perform the same function. Gene redundancy can result from gene duplication. Such duplication events are responsible for many sets of paralogous genes. When an individual gene in such a set is disrupted by mutation or targeted knockout, there can be little effect on phenotype as a result of gene redundancy, whereas the effect is large for the knockout of a gene with only one copy. Gene knockout is a method utilized in some studies aiming to characterize the maintenance and fitness effects functional overlap. Classical models of maintenance propose that duplicated genes may be conserved to various extents in genomes due to their ability to compensate for deleterious loss of function mutations.Nowak MA, Boerlijst MC, Cooke J, Smith JM. 1997. nowak_smith_1997_evolution_of_genetic_redundancy_Nature97. 275:1–5. sftp://[email protected]/home/cerca/Desktop/data/laptop_files/info/biologia/filogeny_evolut ...

Redundant (song)
"Redundant" is a song by American rock band Green Day. It was released as the third single from their fifth album, ''Nimrod'', in April 1998 and serves as the album's fourth track. Although the song failed to match the chart positions of its predecessors, it did reach number two in Australia when it was reissued as a double A-side with "Good Riddance (Time of Your Life)", becoming the band's highest-charting solo single there. Background Before the ''Nimrod'' sessions, Billie Joe Armstrong's marriage had been deteriorating, with the singer arguing with his wife Adrienne Armstrong constantly. Influenced by this conflict, Armstrong reflected on the relationship from two standpoints; the first being his passion for his wife, the second being the repetitious pattern that the relationship had fallen into. The phrase "I love you" had lost its effectiveness and seemed to be said merely out of routine. It is one of few Green Day songs in which vocalist/guitarist Billie Joe Armstrong uses ...

Redundant (play)
''Redundant'' by Leo Butler premiered at the Royal Court Theatre in 2001 starring Lyndsey Marshal and directed by Dominic Cooke. Set in seventeen-year-old Lucy's Sheffield council flat, the play follows a year in the promiscuous teenager's life as she makes one disastrous choice after another. It is a dark, often humorous, examination of social poverty. In the introduction in his collected volume of plays, Butler writes of his central character, "Though she is a victim of poverty - in particular, poverty of imagination and of opportunity - Lucy is never a victim in her own home. She never gives up, and both her dreams, however delusional, and her tough, oppositional spirit remain unspoiled even by the end of the play." It contained the first ever reference in theatre to Osama bin Laden where a character said that the whole country needed to be bombed by him to teach us all what suffering was. The play premiered at Royal Court on 12 September 2001 (the day after the attacks on t ...
