The movement of a body, or link, is studied using geometry so the link is considered to be rigid. [1] The connections between links are modeled as providing ideal movement, pure rotation or sliding for example, and are called joints. A linkage modeled as a network of rigid links and ideal joints is called a kinematic chain.
In this convention, coordinate frames are attached to the joints between two links such that one transformation is associated with the joint [Z ], and the second is associated with the link [X ]. The coordinate transformations along a serial robot consisting of n links form the kinematics equations of the robot: [] = [] [] [] [] …
Gene mapping or genome mapping describes the methods used to identify the location of a gene on a chromosome and the distances between genes. [2] [3] Gene mapping can also describe the distances between different sites within a gene. The essence of all genome mapping is to place a collection of molecular markers onto their respective positions ...
Genetic linkage is the tendency of DNA sequences that are close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction.Two genetic markers that are physically near to each other are unlikely to be separated onto different chromatids during chromosomal crossover, and are therefore said to be more linked than markers that are far apart.
Considering first link P 1-A: all points on this link, including point A, rotate around point P 1. Since P 1 is the only point not moving in the given plane it may be called the instant center of rotation for this link. Point A, at distance P 1-A from P 1, moves in a circular motion in a direction perpendicular to the link P 1-A, as indicated ...
Relative dating by biostratigraphy is the preferred method in paleontology and is, in some respects, more accurate. [1] The Law of Superposition, which states that older layers will be deeper in a site than more recent layers, was the summary outcome of 'relative dating' as observed in geology from the 17th century to the early 20th century.
In network theory, link prediction is the problem of predicting the existence of a link between two entities in a network. Examples of link prediction include predicting friendship links among users in a social network, predicting co-authorship links in a citation network, and predicting interactions between genes and proteins in a biological network.
A protocol-relative URL (PRURL) is the method for linking to a website that offers both HTTP and HTTPS, while HTTPS links should be used for HTTPS-only websites and HTTP links should be used for sites that don't support HTTPS at all. [1] For example, the Internet Archive supports both protocols and thus a PRURL could be used when linking to the ...
