CUBIC is congestion control algorithm designed keeping in mind the issues with networks having high bandwidth delay product. It is current congestion control algorithm being used in Linux kernels. The algorithm modifies the linear increase function of TCP to a cubic function. It also has a better response time and maintains the fairness against concurrent TCP flows. It exhibits a TCP friendly nature over a much vast range of values for Round Trip Time, Bandwidth and Error Rate. But, it also has a problem of aggressive increase and slow convergence of flows causing prolonged unfairness for short lived flows. We have tried to understand these implications of the CUBIC TCP algorithm and explore reasons and suggest solutions for them. The solutions suggested are not purely mathematical but, they lay a foundation for a full fledged algorithm gives hints towards what improvements should be implemented to better the performance of CUBIC. For studying and analysis we have implemented CUBIC in Linux and simulated it in ns-2.

Vision for Interactivity: By Priyanka Sharma To build a Watermarking Model Using MATLAB. There is an increasing need of software so a battle begins between in order to provide copyright protection for intellectual property that's in digital format. For instance, the widely used DCT coefficients used in the JPEG and MPEG-2 standards. In fact when working on the DCT coefficients domain one may take advantage of the relative independence between the maximum allowable perturbations at every coefficients.

Management is creative problem solving. This creative problem solving is accomplished through four functions of management: planning, organizing, leading and controlling. The intended result is the use of an organization's resources in a way that accomplishes its mission and objectives. A manager must organize these functions in order to reach company goals and maintain a competitive advantage. Putting these plans into action requires forming groups as underlings must be directed to complete the plan, and the plan's development must be directed by control. In order for these practices to succeed in an operational manner, an understanding must be reached concerning the basics in which these practices are in relationship to the business structure. Planning is the ongoing process of developing the business' mission and objectives and determining how they will be accomplished. Planning includes both the broadest view of the organization, e.g., its mission, and the narrowest, e.g., a tactic for accomplishing a specific goal.
