A tree topology, or star-bus topology, is a hybrid network topology in which star networks are interconnected via bus networks. [ 1 ] [ 2 ] Tree networks are hierarchical, and each node can have an arbitrary number of child nodes.
Graphic organizers have a history extending to the early 1960s. David Paul Ausubel was an American psychologist who coined the phrase "advance organizers" to refer to tools which bridge "the gap between what learners already know and what they have to learn at any given moment in their educational careers."
A concept map or conceptual diagram is a diagram that depicts suggested relationships between concepts. [1] Concept maps may be used by instructional designers, engineers, technical writers, and others to organize and structure knowledge.
They can be considered "are a type of non-linear graphic organizer that can help to systematize the generation of ideas based upon a central topic. Using this type of diagram... can more easily brainstorm a theme, associate about an idea, or explore a new subject". [2] Also, the term cluster diagrams is sometimes used as synonym of mind maps". [3]
As discussed above, the algorithm starts by computing sub-tree frequencies in the network and then expands sub-trees edge by edge. One way to implement this idea is called the expansion tree T k for each k. Figure shows the expansion tree for size-4 sub-graphs. T k organizes the running process and provides query graphs in a hierarchical manner.
A sample network diagram Readily identifiable icons are used to depict common network appliances, e.g. routers, and the style of lines between them indicates the type of connection. Clouds are used to represent networks external to the one pictured for the purposes of depicting connections between internal and external devices, without ...
A graphic organizer can be used as a teaching tool in two ways: From graphic organizer to text – A completed sequence organizer is used to create a piece of writing based on the information it contains. From text to graphic organizer – A sequence organizer is used to simplify, in note form, events in a sequential order.
An example of complex scale-free network. A network is called scale-free [7] [15] if its degree distribution, i.e., the probability that a node selected uniformly at random has a certain number of links (degree), follows a mathematical function called a power law. The power law implies that the degree distribution of these networks has no ...
