Cellular Automaton
A cellular automaton (pl. cellular automata, abbrev. CA) is a discrete model of computation studied in automata theory. Cellular automata are also called cellular spaces, tessellation automata, homogeneous structures, cellular structures, tessellation structures, and iterative arrays. Cellular automata have found application in various areas, including physics, theoretical biology and microstructure modeling. A cellular automaton consists of a regular grid of ''cells'', each in one of a finite number of '' states'', such as ''on'' and ''off'' (in contrast to a coupled map lattice). The grid can be in any finite number of dimensions. For each cell, a set of cells called its ''neighborhood'' is defined relative to the specified cell. An initial state (time ''t'' = 0) is selected by assigning a state for each cell. A new ''generation'' is created (advancing ''t'' by 1), according to some fixed ''rule'' (generally, a mathematical function) that determines the new state of e ...

Cell Biology
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. Cell biology is the study of structural and functional units of cells. Cell biology encompasses both prokaryotic and eukaryotic cells and has many subtopics which may include the study of cell metabolism, cell communication, cell cycle, biochemistry, and cell composition. The study of cells is performed using several microscopy techniques, cell culture, and cell fractionation. These have allowed for and are currently being used for discoveries and research pertaining to how cells function, ultimately giving insight into understanding larger organisms. Knowing the components of cells and how cells work is fundamental to all biological sciences while also being essential for research in biomedical fields such as ...

Cellular (film)
''Cellular'' is a 2004 American action thriller film directed by David R. Ellis. The film stars Kim Basinger, Chris Evans, Jason Statham, William H. Macy with Noah Emmerich, Richard Burgi, Valerie Cruz and Jessica Biel. The screenplay was written by Chris Morgan, based on a story by Larry Cohen. The film was released on September 10, 2004. It received mixed reviews from critics and grossed $57 million. Plot Science teacher Jessica Martin lives with her husband Craig and their son Ricky. One morning, after Jessica takes Ricky to the bus stop, intruders break into her house, slay her housekeeper, kidnap and confine her in an attic, and smash the landline. Jessica manages to use the wires of the broken phone to contact a random number. Ryan is hanging out at Santa Monica Pier with his friend Chad when he comes across his ex, Chloe, who dumped him. Hoping to get back with her, he offers to help with the fundraiser being held there; he gets Chad to hand out the fliers until he retu ...

Cellular Frequencies
Cellular frequencies are the sets of frequency ranges within the ultra high frequency band that have been assigned for cellular-compatible mobile devices, such as mobile phones, to connect to cellular networks.Guowang Miao, Jens Zander, Ki Won Sung, and Ben Slimane, Fundamentals of Mobile Data Networks, Cambridge University Press, , 2016. Most mobile networks worldwide use portions of the radio frequency spectrum, allocated to the mobile service, for the transmission and reception of their signals. The particular bands may also be shared with other radiocommunication services, e.g. broadcasting service, and fixed service operation. Overview Radio frequencies used for cellular networks differ in ITU Regions (Americas, Europe, Africa and Asia). The first commercial standard for mobile connection in the United States was AMPS, which was in the 800 MHz frequency band. In Nordic countries of Europe, the first widespread automatic mobile network was based on the NMT-450 standa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cellular Manufacturing
Cellular manufacturing is a process of manufacturing which is a subsection of just-in-time manufacturing and lean manufacturing encompassing group technology. The goal of cellular manufacturing is to move as quickly as possible, make a wide variety of similar products, while making as little waste as possible. Cellular manufacturing involves the use of multiple "cells" in an assembly line fashion. Each of these cells is composed of one or multiple different machines which accomplish a certain task. The product moves from one cell to the next, each station completing part of the manufacturing process. Often the cells are arranged in a "U-shape" design because this allows for the overseer to move less and have the ability to more readily watch over the entire process. One of the biggest advantages of cellular manufacturing is the amount of flexibility that it has. Since most of the machines are automatic, simple changes can be made very rapidly. This allows for a variety of scaling f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cellular Network
A cellular network or mobile network is a communication network where the link to and from end nodes is wireless. The network is distributed over land areas called "cells", each served by at least one fixed-location transceiver (typically three cell sites or base transceiver stations). These base stations provide the cell with the network coverage which can be used for transmission of voice, data, and other types of content. A cell typically uses a different set of frequencies from neighboring cells, to avoid interference and provide guaranteed service quality within each cell. When joined together, these cells provide radio coverage over a wide geographic area. This enables numerous portable transceivers (e.g., mobile phones, tablets and laptops equipped with mobile broadband modems, pagers, etc.) to communicate with each other and with fixed transceivers and telephones anywhere in the network, via base stations, even if some of the transceivers are moving through more than ...

Cellular Organizational Structures
A non-biological entity with a cellular organizational structure (also known as a cellular organization, cellular system, nodal organization, nodal structure, et cetera) is set up in such a way that it mimics how natural systems within biology work, with individual 'cells' or 'nodes' working somewhat independently to establish goals and tasks, administer those things, and troubleshoot difficulties." These cells exist in a broader network in which they frequently communicate with each other, exchanging information, in a more or less even organizational playing field. Numerous examples have existed both in economic terms as well as for groups working towards other pursuits. This structure, as applied in areas such as business management, exists in direct contrast to traditional hierarchical leadership that is seen in institutions such as United States federal government agencies, where one type of supervisor gives specific orders to another supervisor and so on down the line.

Clandestine Cell Organizations
A clandestine cell system is a method for organizing a group of people (such as resistance fighters, sleeper agents, mobsters, or terrorists) such that such people can more effectively resist penetration by an opposing organization (such as law enforcement or military units). In a cell structure, each of the small groups of people in the cell know the identities of the people only in their own cell. Thus any cell member who is apprehended and interrogated (or who is a mole) will not likely know the identities of the higher-ranking individuals in the organization. The structure of a clandestine cell system can range from a strict hierarchy to an extremely distributed organization, depending on the group's ideology, its operational area, the communications technologies available, and the nature of the mission. Criminal organizations, undercover operations, and unconventional warfare units led by special forces may also use this sort of organizational structure. Covert oper ...
