A lot of information is available in the medical databases about the patients, doctors and diseases. Extraction of useful knowledge and providing scientific decision making for the diagnosis and treatment of the diseases from these databases increasingly become necessary. The medical databases need the use of data mining algorithms to find the hidden facts. Knowledge discovery and data mining methods have been applied to discover hidden patterns and relations in complex datasets using intelli...
CLUSTERING In data mining, Clustering is considered as an important technique to differentiate various groups of datasets, classes or clusters within a set of objects. The data objects those are similar to each other are grouped together to be placed in the same cluster, while the objects different to one another are placed in different groups or clusters. Faber has defined clustering as "the method to divide a given set of data points into distinct and non-overlapping groups or clusters, in ...
The complexity of the graph matching approaches make it very difficult to take into account all types of dependencies between the vertices and edges in the model and data graphs. That is why in most existing frameworks defined for this problem only unary and binary relations between vertices are taken into account. The advantage of such simplifications is that the complexity of graph matching is reduced when tackling the original problem , and this allows the use of techniques that require ev...
Abstract: Multimedia applications present new challenges to the current networking technology. One of them is Quality of Service (QoS) requirement. Due to the increasing dynamics of traffic introduced by multimedia applications, dynamic and flexible QoS (Quality of Service) control is needed to ensure both QoS satisfaction and resource efficiency. Because integrated service networks are designed to support a wide range of traffic classes, which have different service requirements, developing ...
This chapter includes a detailed introduction regarding my thesis work. My thesis work is basically on stream cipher that is geffe generator. Stream ciphers are an important class of keystream generation algorithms. They usually encrypt individual characters (binary digits) of a plain text message one time at a time, using an encryption transformation which varies with time. Feedback shift registers particularly linear feedback shift registers are the basic components of many key stream gener...
Multimedia databases represent a powerful solution to those entities that require their data be stored in its original multimedia format. This type of database has the same concepts as the normal well-known information-storing database. Miscellaneous queries can be done on these multimedia data formats, thus the entire concept and use of a database system is successfully fulfilled. Multimedia have various forms such as documents, images, video and audio clips. [Elmasri and Navathe, 2007] Data...
In vehicular network message validation is one of the key factor of ITS, as valid message improves the route planning, road safety and traffic management. The proposed scheme called ABC is about the scrutiny of the message whether the message received is valid or not. Invalid message in real time urban environment can cause mess at a large number that may lead to a serious/fatal results. So in this paper we propose a scheme that focuses on the validity of the message by testing the trust leve...
Time-division multiplexing (TDM) is a way of combining multiple data streams in a single signal by separating the signal into many segments, each having a very short duration. Each of the individual data stream is reassembled and quite the same at the receiving end based on the timing.[2] A multiplexer or a demultiplexer is required by a two-way communications circuit at each end of the long-distance, high-bandwidth cable. Multiplexer is a circuit that combines signals at the transmitting end...
Web search engines are keys to the immense treasure of information. Dependency on the search engines is increasing drastically for both personal and professional use. It has become essential for the users to understand the differences between the search engines in order to attain a higher satisfaction. There is a great assortment of search engines which offer various options to the web user. Thus, it is significant to evaluate and compare search engines in the quest of a single search engine ...
The objective of this report is to determine type of modulation or type of Communication system can be associated with the experiments individually. Determining the output variations with the change in circuit parameters. VisSim/Comm software is an application in which the model communication system block diagrams are formed with the components available in the VisSim/Com tool kit. It is also termed as the block diagram language for the simulation of the dynamic systems and embedded systems a...
