A $it{weighted~slant~Toep}$-$it{Hank}$ operator $L_{phi}^{beta}$ with symbol $phiin L^{infty}(beta)$ is an operator on $L^2(beta)$ whose representing matrix consists of all even (odd) columns from a weighted slant Hankel (slant weighted Toeplitz) matrix, $beta={beta_n}_{nin mathbb{Z}}$ be a sequence of positive numbers with $beta_0=1$. A matrix characterization for an operator to be $it{weighte...

We propose to strengthen user-selected passwords against statistical-guessing attacks by allowing users of Internetscale systems to choose any password they want—so long as it’s not already too popular with other users. We create an oracle to identify undesirably popular passwords using an existing data structure known as a count-min sketch, which we populate with existing users’ passwords and ...

As we, all know that in every field it is very important to have quality of services. In the field of Real-time, applications like ATM and Wi-Fi are few examples. Some metrics for quality of services are Cost, Flexibility, Reliability and Efficiency. In this paper, we deal with quality of services in relation to admission control of the packets. In admission control, it should concentrate on sc...

The max-min fairness is one of the most widely used fairness concepts for resource sharing in communication networks. This paper describes some results related to it.

Skewness plays a very important role in task scheduling. It measures the degree of asymmetry in a data set. Moreover, the data set may be positively skewed or negatively skewed. The quartile coefficient of skewness lies in between -1 to 1. If the quartile coefficient is in between -1 to 0, then the data set is negatively skewed. Otherwise, it is positively skewed. Min-Min and Max-Min heuristic ...

Let be a locally compact non?abelian group and be a compact subgroup of also let be a ?invariant measure on the homogeneous space . In this article, we extend the linear operator as a bounded surjective linear operator for all ?spaces with . As an application of this extension, we show that each frame for determines a frame for and each frame for arises from a frame in via...
