There are six " groups " into which dives are classified: Forward, Back, Inward, Reverse, Twist, and Armstand.

Among his contributions to computer science are the shortest path algorithm, also known as Dijkstra's algorithm ; Reverse Polish Notation and related Shunting yard algorithm ; the THE multiprogramming system, an important early example of structuring a system as a set of layers ; Banker's algorithm ; and the semaphore construct for coordinating multiple processors and programs.

Reverse faults, particularly those along convergent plate boundaries are associated with the most powerful earthquakes, including almost all of those of magnitude 8 or more.

As is the case with Reverse Polish notation, although R1C1-style formulas are more efficient than A1-style formulae ( for instance, relative and absolute references can be mixed in the same expression, as " R1C " to mean " row 1, this column "), most spreadsheet users prefer the A1 addressing style introduced by VisiCalc.

Reverse transcribing viruses replicate their genomes by reverse transcribing DNA copies from their RNA ; these DNA copies are then transcribed to new RNA.

Reverse flow viscometers have the reservoir above the markings and direct flow are those with the reservoir below the markings.

The activity of retrodiction ( or postdiction ) involves moving backwards in time, step-by-step, in as many stages as are considered necessary, from the present into the speculated past, in order to establish the ultimate cause of a specific event ( e. g., Reverse engineering and Forensics ).

Sirens are sometimes used as part of an integrated warning system that links sirens with other warning media such as the radio and TV Emergency Alert System, NOAA Weather Radio, telephone alerting systems, Reverse 911, Cable Override and wireless alerting systems in the United States and the Emergency Public Warning System in the Canadian province of Alberta.

Telomeres are extended by telomerases, part of a protein subgroup of specialized reverse transcriptase enzymes known as TERT ( TElomerase Reverse Transcriptases ) that are involved in synthesis of telomeres in humans and many other, but not all, organisms.

Reverse electron transitions for all these types of excited molecules are also possible to return to their ground states, which can be designated as σ *→ σ, π *→ π, or π *→ n.

* Reverse auction is a type of auction in which the roles of the buyer and the seller are reversed, with the primary objective to drive purchase prices downward.

Except for Reverse proxy, the types of proxies described in this article are more specialized sub-types of the general forward proxy concept.

Reverse proxies are installed in the neighborhood of one or more web servers.

Reverse appliqué is a sewing technique where a ground fabric is cut, and another piece of fabric is placed under the ground fabric, and the raw edges of the ground fabric are tucked under and the newly folded edge is sewn down to the lower fabric.

Reverse appliqué techniques are often used in combination with traditional appliqué techniques, to give a variety of visual effects.

* Reverse appliqué: several layers of material are stitched together, parts of the upper layers are cut away, and the edges are stitched down.

* A Reverse starburst is an arrayed pattern of grooves or recesses that are engraved or molded into the inner faces of the yo-yo.

However these researches are not philosophies of mathematics but rather the study of restricted forms of reasoning similar to Reverse Mathematics.

The ranks in each color are 0 through 9, " Skip ", " Draw Two " and " Reverse ".

The term Polish notation is sometimes taken ( as the opposite of infix notation ) to also include Polish postfix notation, or Reverse Polish notation, in which the operator is placed after the operands.

Reverse transcriptase is used also to create cDNA libraries from mRNA.

Reverse transcriptase has also been employed in insulin production.

Reverse logistics is also referred to as " Aftermarket Customer Services ".

The Kinked design also fares well in parks as it has the turning and spin benefits of the " Reverse " camber design.

Reverse engineering has also revealed the secrets of some synthesizer components, such as those from ARP Instruments, Inc.

Reverse discrimination may also be used to highlight the discrimination inherent in affirmative action programs.

Reverse transcriptase is essential for the reproduction of retroviruses such as HIV and was also discovered independently, and at about the same time, by Mizutani and Temin.

Reverse sexual imprinting is also seen in instances where two people who live in close domestic proximity during the first few years in the life of either one become desensitized to later close sexual attraction.

* postfix notation, also called Reverse Polish notation

Reverse biasing the emitter-base junctions of transistors also is quite effective as long as the A. C. amplitude remains small.

Reverse transcription PCR is not to be confused with real-time polymerase chain reaction ( Q-PCR / qRT-PCR ), which is also sometimes abbreviated as RT-PCR.

Reverse domain name hijacking ( also known as reverse cybersquatting ), occurs where a trademark owner attempts to secure a domain name by making false cybersquatting claims against a domain name ’ s rightful owner.

It can also be used to secure access to internal web servers ( Reverse proxy ).

The services of 1800 Reverse are also available in Australia.

The RPL programming language ( RPL meaning ROM-based procedural language following Hewlett-Packard or, alternatively, Reverse Polish LISP ) is a handheld calculator system and application programming language used on Hewlett-Packard's engineering graphing RPN calculators of the HP-28, HP-48, HP-49 and HP-50 series, but it is also usable on non-RPN calculators, such as the HP-39 series.

Reverse perspective, also called inverse perspective, inverted perspective or Byzantine perspective, is a convention of perspective drawing where the further the objects are, the larger they are drawn.

In the final battle, plays while the player combats Sephiroth's first form, " Bizarro Sephiroth " ( also known as " Reverse Sephiroth ").

" Reverse Sephiroth " was also released as a normal figure in volume 2.

Reverse is also a pair of gears: one gear on the countershaft and one on the output shaft.

A video for " In Reverse " was also released.

Reverse psychology can also prey on a person's ego, as when it is used, it can make the target feel incompetent ; effectively persuading the person to perform the desired action.
