A life-critical system or safety-critical system is a system whose failure or malfunction may result in: death or serious injury to people, or loss or severe damage to equipment or environmental harm. Life-critical system

Topological vector space The addition operation is continuous at 0 if and only if for every neighborhood U of 0 there exists another neighborhood V of 0 such that the Minkowski sum V + V is contained in U . In mathematics , a topological vector space (also called a linear topological space ) is one of the basic structures investigated in functional analysis .
In functional analysis and related areas of mathematics , a sequence space is a vector space whose elements are infinite sequences of real or complex numbers . Equivalently, it is a function space whose elements are functions from the natural numbers to the field K of real or complex numbers. Sequence space
In mathematics , informally speaking, a sequence is an ordered list of objects (or events). Like a set , it contains members (also called elements , or terms ). The number of ordered elements (possibly infinite) is called the length of the sequence. Sequence
Autonomic nervous system The autonomic nervous system ( ANS or visceral nervous system or involuntary nervous system ) is the part of the peripheral nervous system that acts as a control system , functioning largely below the level of consciousness , and controls visceral functions. [ 1 ] The ANS effects heart rate , digestion , respiratory rate , salivation , perspiration , pupillary dilation , micturition (urination), and sexual arousal . Most autonomous functions are involuntary but a number of ANS actions can work alongside some degree of conscious control . Everyday examples include breathing, swallowing, and sexual arousal, and in some cases functions such as heart rate .

## Network topology

Network topology is the arrangement of the various elements ( links , nodes , etc.) of a computer [ 1 ] [ 2 ] or biological network . [ 3 ] Essentially, it is the topological [ 4 ] structure of a network, and may be depicted physically or logically. Physical topology refers to the placement of the network's various components, including device location and cable installation, while logical topology shows how data flows within a network, regardless of its physical design. Distances between nodes, physical interconnections, transmission rates, and/or signal types may differ between two networks, yet their topologies may be identical. A good example is a local area network (LAN): Any given node in the LAN has one or more physical links to other devices in the network; graphically mapping these links results in a geometric shape that can be used to describe the physical topology of the network.
A tag cloud with terms related to Web 2.0 A tag cloud ( word cloud , or weighted list in visual design) is a visual representation for text data, typically used to depict keyword metadata (tags) on websites, or to visualize free form text. Tags are usually single words, and the importance of each tag is shown with font size or color. [ 1 ] This format is useful for quickly perceiving the most prominent terms and for locating a term alphabetically to determine its relative prominence. When used as website navigation aids, the terms are hyperlinked to items associated with the tag. [ edit ] History In the language of visual design, a tag cloud (or word cloud) is one kind of "weighted list", as commonly used on geographic maps to represent the relative size of cities in terms of relative typeface size. Tag cloud
In linear algebra , an orthogonal matrix is a square matrix with real entries whose columns and rows are orthogonal unit vectors (i.e., orthonormal vectors). Equivalently, a matrix Q is orthogonal if its transpose is equal to its inverse : which entails where I is the identity matrix . An orthogonal matrix Q is necessarily invertible (with inverse Q −1 = Q T ), unitary ( Q −1 = Q * ), and normal ( Q * Q = QQ * ). Orthogonal matrix
Illustration of electrophoresis Illustration of electrophoresis retardation Electrophoresis is the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field . [ 1 ] [ 2 ] [ 3 ] [ 4 ] [ 5 ] [ 6 ] This electrokinetic phenomenon was observed for the first time in 1807 by Ferdinand Frederic Reuss ( Moscow State University ), [ 7 ] who noticed that the application of a constant electric field caused clay particles dispersed in water to migrate. Electrophoresis
Glossary A glossary , also known as an vocabulary , or clavis , is an alphabetical list of terms in a particular domain of knowledge with the definitions for those terms. Traditionally, a glossary appears at the end of a book and includes terms within that book that are either newly introduced, uncommon, or specialized. A bilingual glossary is a list of terms in one language defined in a second language or glossed by synonyms (or at least near-synonyms) in another language.
Shuttle The original meaning of the word shuttle is the device used in weaving to carry the weft. By reference to the continual to-and-fro motion associated with that, the term was then applied in transportation and then in other spheres. Thus the word may now also refer to:
Hub Hub , or Hubs may refer to: [ edit ] Wheels Bicycle hub , the central part of a bicycle wheel Locking hubs , accessory on four-wheel drive vehicles Wheel hub assembly , an automotive part [ edit ] Buildings
