    Abstract

    A novel conformal mapping based Fractional Order (FO) methodology is
    developed in this paper for tuning existing classical (Integer Order)
    Proportional Integral Derivative (PID) controllers especially for sluggish and
    oscillatory second order systems. The conventional pole placement tuning via
    Linear Quadratic Regulator (LQR) method is extended for open loop oscillatory
    systems as well.

    Abstract

    Phase shaping using fractional order (FO) phase shapers has been proposed by
    many contemporary researchers as a means of producing systems with iso-damped
    closed loop response due to a stepped variation in input. Such systems, with
    the closed loop damping remaining invariant to gain changes can be used to
    produce dead-beat step response with only rise time varying with gain.

    Abstract

    Web application (WA) expands its usages to provide more and more services and
    it has become one of the most essential communication channels between service
    providers and the users. To augment the users experience many web applications
    are using client side scripting languages such as JavaScript but this growing
    of JavaScript is increasing serious security vulnerabilities in web application
    too, such as cross site scripting (XSS). In this paper, I survey all the
    techniques those have been used to detect XSS and arrange a number of analyses
    to evaluate performances of those methodologies.
