uncontrolled means, e.g. dropped by a helicopter, and to collectively form a network in an ad-hoc manner. In order to achieve high energy efficiency and increase the network scalability, sensor nodes can be organized into clusters. Data collected from sensors are sent to the cluster head first, and then forwarded to the base station. Network lifetime can be defined as the time elapsed until the first node (or the last node) in the network depletes its energy (dies). A number

SEGMENTATION OF BRAIN MR IMAGES FOR TUMOR AREA AND SIZE DETECTION BY USING OF CLUSTERING ALGORITHM Shinu Sadeyone1 Assistant professor (Sathyabama University, Chennai) S.Freeda2 Assistant professor (A.C.T engineering college, Chngalpattu) 1shinusedayone@gmail.com. 2freeda27@gmail.com. Abstract- There are different types of tumors are available. Astrocytoma is the most common type of tumor (30% of all brain tumor) and is usually a malignant one. Astrocytoma can be subdivided into four grades

of two algorithms K-means and Apriori, their explanation using flow chart and pseudo code, and comparison for time and space complexity of the two for the dataset of an “Online Retail Shop”. General Terms Data Mining, Algorithms et. al. Keywords Clusters, data sets, item, centroid, distance, converge, frequent item sets, candidates. 1. INTRODUCTION Data Mining in Cloud Computing applications is data retrieving from huge collection of data sets. The process of converting a huge set of data

1.0 Introduction In today’s competitive environment, maintaining customer relationships is a key to business success because customers are considered as important strategic resources of a business. However, all business markets contain many subgroups of customers that behave differently, that have different ambitions, and have different purchasing behaviours. Hence each subgroup must be treated differently in order to build strong customer relationships. To compete with rival businesses, it is vital

A convenience sample is made up of people who are easy to reach. The main types of probability sampling methods are simple random sampling, stratified sampling, cluster sampling, multistage sampling, and systematic random sampling. The key benefit of probability sampling methods is that they guarantee that the sample chosen is representative of the population. This ensures Simple random sampling. Simple random sampling

For cluster-based WSNs (CWSNs), secure data transmission, where like dynamically and periodically the clusters are shaped. The analysis problems associated with WSNs security and knowledge aggregation with reference to the protection and security analysis against various attacks, we show the quality of being usable of the SET-IBS and SET-IBOOS protocols. For a fuzzy approach and SET-IBS formula employing a combination in our planned system, for WSNs a replacement routing technique to extend network

1. What is the purpose of the research? Discuss the type of research being conducted, e.g. applied, quantitative, etc. and explain. The purpose of the research study, “IQ and Delinquency: The Differential Detection Hypothesis Revisited,” is to revisit a previous study, the National Longitudinal Study of Adolescent Health (Add Health), which analyzed the degree to which verbal intelligence affects police arrest and whether disadvantaged neighborhoods affect verbal intelligence on arrest. The type

methods. This paper proposes the k-mean partitioning method of clustering and also provide a comparison of k-mean clustering and Single link HAC . Performance of these clustering techniques are compared according to the execution time based on no of clusters and no of data items being entered. Keyword:Indexing,Data mining,clustering k-Means Clustering, Single Link HAC I. INTRODUCTION Keeping in mind the end goal to encourage quick and precise data recovery, Search engine indexing gathers, parses, and

make the cluster. 5.5.2 Clustering This phase take the input of documents to make the cluster. To make the cluster I have applied an agglomerative approach which is a hierarchal approach. It take 2 document and make one cluster and produce the hierarchy. With this hierarchy approach a hierarchy of cluster like mega cluster ,super clusters are generated by itself which help in the searching in efficient way. Now it can create the index at each level. As it is taking the common words in clusters then

Abstract— With the growth of GPS technology, the location based services in various technologies and devices supporting the location prediction and location based services has opened the area of research. The study and developing the efficiency of location based services has become a thrust area of research. Prediction of moving objects which can help to provide a better quality of service. The efficiency of the trajectory data depends on the efficiency and effective processing of the data. This
