The result is a set of non-linear equations that define the configuration parameters of the system for a set of values for the input parameters. Freudenstein introduced a method to use these equations for the design of a planar four-bar linkage to achieve a specified relation between the input parameters and the configuration of the linkage.
A straight-line mechanism is a mechanism that converts any type of rotary or angular motion to perfect or near-perfect straight-line motion, or vice versa. Straight-line motion is linear motion of definite length or "stroke", every forward stroke being followed by a return stroke, giving reciprocating motion. The first such mechanism, patented ...
For example, complete-linkage tends to produce more spherical clusters than single-linkage. The linkage criterion determines the distance between sets of observations as a function of the pairwise distances between observations. Some commonly used linkage criteria between two sets of observations A and B and a distance d are:
In linear algebra, a linear function is a map f between two vector spaces such that. Here a denotes a constant belonging to some field K of scalars (for example, the real numbers) and x and y are elements of a vector space, which might be K itself. In other terms the linear function preserves vector addition and scalar multiplication .
Linked list. A linked list is a sequence of nodes that contain two fields: data (an integer value here as an example) and a link to the next node. The last node is linked to a terminator used to signify the end of the list. In computer science, a linked list is a linear collection of data elements whose order is not given by their physical ...
A slider-crank linkage is a four-link mechanism with three revolute joints and one prisimatic (sliding) joint. [1] The rotation of the crank drives the linear movement of the slider, or the expansion of gases against a sliding piston in a cylinder can drive the rotation of the crank. There are two types of slider-cranks: in-line and offset.
Ether. The general structure of an ether in organic chemistry. R and R' represent most organyl substituent (e.g., alkyl or aryl ). In organic chemistry, ethers are a class of compounds that contain an ether group —an oxygen atom connected to two organyl groups (e.g., alkyl or aryl ). They have the general formula R−O−R′, where R and R ...
Polysaccharide. 3D structure of cellulose, a beta-glucan polysaccharide. Amylose is a linear polymer of glucose mainly linked with α (1→4) bonds. It can be made of several thousands of glucose units. It is one of the two components of starch, the other being amylopectin. Polysaccharides ( / ˌpɒliˈsækəraɪd / ), or polycarbohydrates, are ...
