Distance measures are part and parcel of many computer vision algorithms. The underlying assumption in all existing distance measures is that feature elements are independent and identically distributed. However , in real-world settings, data generally originate from heterogeneous sources even if they do possess a common data-generating mechanism. Since(More)
Web Application are used for providing information and function on World Wide web for various e-commerce organization, medical-care, business and Government sectors which further requires security and vulnerabilities. This paper describes the type of SQL Injection Attacks and discusses the technique, to avoid them. The type of SQL Injection Attack,(More)
In recent years, orthogonal frequency division multiplexing (OFDM) is considered as one of the key technologies for high data wireless communication systems. One of the main disadvantages of an OFDM system is its high peak to average power ratio (PAPR), which causes distortion in signal at the nonlinear high power amplifier (HPA) of OFDM transmitter [1-10].(More)
Clustering is an unsupervised learning technique in which data or objects are grouped into sets based on some similarity measure. Most of the clustering algorithms assume that the main memory is infinite and can accommodate the set of patterns. In reality many applications give rise to a large set of patterns which does not fit in the main memory. When the(More)
Orthogonal frequency division multiplexing (OFDM) is a key modulation technique to provide a high performance physical layer in modern wireless systems. Orthogonal frequency multiple accesses (OFDMA) is one of the best ways to resource allocations in OFDM systems. Resource allocation schemes are required to be optimized to improve performance of OFDMA based(More)
