In this paper we present an algorithm for determining k-nearest neighbor tuples for a given tuple in a set of geographically distributed databases. These databases form a vertical partitioning of some implicit global database. The computation is performed by exchanging minimum number of higher level summaries so that even if they are captured by an intruder to actual data tuples can ever be rev...

This paper presents an improved graph based k-nn algorithm for text classification. Most of the organization are facing problem of large amount of unorganized data. Most of the existing text classification techniques are based on vector space model which ignores the structural information of the document which is the word order or the co-occurrences of the terms or words. In this paper we have ...

The ability of databases to organize and share data often raises privacy concerns. Data warehousing combined with data mining, bringing data from multiple sources under a single authority, increases the risk of privacy violations. Privacy preserving data mining provides a means of addressing this issue, particularly if data mining is done in a way that doesn’t disclose information beyond the re...

Social networks play a major role in today’s society, they have shaped the unfolding of social relationships. To analyze networks dynamics, link prediction i.e., predicting potential new links between actors, is concerned with inspecting networks topology evolution over time. A key issue to be addressed is the imperfection of real world social network data which are usually missing, noisy, or p...

With internet expanding in every aspect of businesses infrastructure, it becomes more and more important to make these businesses infrastructures safe and secure to the numerous attacks perpetrated on them conspicuously when it comes to denial of service (DoS) attack. IP is an internet protocol each and every system having a unique address to use this address to communicate to the internet. The...

Theorem 2.1. For all n ≥ 1, n log n− n < log(n!) < n log n, so log(n!) ∼ n log n. Proof. The inequality log(n!) < n log n is a consequence of the trivial inequality n! < nn. Here are three methods of showing n log n− n < log(n!). Method 1: A Riemann sum approximation for ∫ n 1 log x dx using right endpoints is log 2+ · · ·+ log n = log(n!), which overestimates, so log(n!) > ∫ n 1 log x dx = n l...
