Today, there is a general consensus that, in the near future, wide area networks (WAN)(such as, a nationwides backbone network) will be based on Wavelength Division Multiplexed (WDM) optical networks. One of the main advantages of a WDM WAN over other optical technologies, such as, Time Division Multiplexed (TDM) optical networks, is that it allows us to exploit the enormous bandwidth of an optical fiber (up to 50 terabits bits per second) with requiring electronic devices, which operate at extremely high speeds.

ABSTRACT
Colored Trees (CTs) is an efficient approach to route packets along link-or node-disjoint paths in packet-switched networks. her two trees, namely red and blue, are constructed rooted at a drain such that the path from any node to the drain are link-or node-disjoint. For applications where both the trees are used simultaneously, it is critical to maintain the trees after page link or node failures. this seminar discuss an algorithm, referred to as SimCT, that efficiently constructs and maintains colored trees under failures using only ....etc

ABSTRACT
For languages without word boundary delimiters, dictionaries are
needed for segmenting running texts. This figure makes
segmentation accuracy depend significantly on the quality of the
dictionary used for analysis. If the dictionary is not sufficiently
good, it will lead to a great number of unknown or unrecognized
words. These unrecognized words certainly reduce segmentation
accuracy. To solve such problem, we propose a method based on
decision tree models. Without use of a dictionary, specific
information, called syn ....etc

DISTRIBUTED ALGORITHMS FOR CONSTRUCTING APPROXIMATE MINIMUM SPANNING TREES IN WIRELESS SENSOR NETWORKS --PARALLEL AND DISTRIBUTED SYSTEMS

While there are distributed algorithms for the minimum spanning tree (MST) problem, these algorithms require relatively large number of messages and time, and are fairly involved, making them impractical for resource-constrained networks such as wireless sensor networks. In such networks, a sensor has very limited power, and any algorithm needs to be simple, local, and energy efficient. Motivated by these ....etc

Decision Trees

DECISION TREE

An internal node is a test on an attribute.
A branch represents an outcome of the test, e.g., Color=red.
A leaf node represents a class label or class label distribution.
At each node, one attribute is chosen to split training examples into distinct classes as much as possible
A new case is classified by following a matching path to a leaf node.
