Joint application design is a term originally used to describe a software development process pioneered and deployed during the mid-1970s by the New York Telephone Company 's Systems Development Center under the direction of Dan Gielan. Following a series of implementations of this methodology, Gielan lectured extensiv... | https://en.wikipedia.org/wiki/Joint_application_design |
In anatomy , a joint capsule or articular capsule is an envelope surrounding a synovial joint . [ 1 ] Each joint capsule has two parts: an outer fibrous layer or membrane, and an inner synovial layer or membrane.
Each capsule consists of two layers or membranes:
On the inside of the capsule, articular cartilage cover... | https://en.wikipedia.org/wiki/Joint_capsule |
Joint constraints are rotational constraints on the joints of an artificial system. [ 1 ] They are used in an inverse kinematics chain, in fields including 3D animation or robotics . [ 2 ] Joint constraints can be implemented in a number of ways, but the most common method is to limit rotation about the X, Y and Z axis... | https://en.wikipedia.org/wiki/Joint_constraints |
In universal algebra and model theory , a class of structures K is said to have the joint embedding property if for all structures A and B in K , there is a structure C in K such that both A and B have embeddings into C .
It is one of the three properties used to define the age of a structure.

In audio engineering , joint encoding is the joining of several channels of similar information during encoding in order to obtain higher quality, a smaller file size, or both.
The term joint stereo has become prominent as the Internet has allowed for the transfer of relatively low bit rate , acceptable-quality audio ... | https://en.wikipedia.org/wiki/Joint_encoding |
In information theory , joint entropy is a measure of the uncertainty associated with a set of variables . [ 1 ]
The joint Shannon entropy (in bits ) of two discrete random variables X {\displaystyle X} and Y {\displaystyle Y} with images X {\displaystyle {\mathcal {X}}} and Y {\displaystyle {\mathcal {Y}}} is defined... | https://en.wikipedia.org/wiki/Joint_entropy |
In the United States Armed Forces , the joint precision approach and landing system ( JPALS ) is an all-weather system for precision guidance of landing aircraft.

The joint quantum entropy generalizes the classical joint entropy to the context of quantum information theory . Intuitively, given two quantum states ρ {\displaystyle \rho } and σ {\displaystyle \sigma } , represented as density operators that are subparts of a quantum system, the joint quantum entropy is a measure o... | https://en.wikipedia.org/wiki/Joint_quantum_entropy |
In information theory , joint source–channel coding is the encoding of a redundant information source for transmission over a noisy channel , and the corresponding decoding , using a single code instead of the more conventional steps of source coding followed by channel coding .

A joist is a horizontal structural member used in framing to span an open space, often between beams that subsequently transfer loads to vertical members. When incorporated into a floor framing system, joists serve to provide stiffness to the subfloor sheathing, allowing it to function as a horizontal diaphragm .
