Adaptive Non-linear Congestion Controller for Differentiated-Services Framework (Java)
IEEE/ACM Transactions on Networking, Vol. 13, No. 1, February 2005

Abstract:
The growing demand of computer usage requires efficient ways of managing network traffic in order to avoid or at least limit the level of congestion in cases where increases in bandwidth are not desirable or possible. In this paper we developed and analyzed a generic Integrated Dynamic Congestion Control (IDCC) scheme for controlling traffic using information on the stat ....etc

Abstract


A robust/adaptive stochastic observer is presented for stochastic nonlinear dynamics having excessive uncertainties. It was shown through a new theorem that the proposed nonlinear robust sliding mode observer has very accurate state estimate error characteristic. The observer uses the sliding mode technique for the robustness and a deterministic adaptive law to guarantees a globally asymptotically convergence observation error. Finally, an example is given to illustrat ....etc

The primary objective of a design engineer is to ensure a safe, efficient design of equipment to carry out a process. This needs a good understanding of the various processes occurring in the system. The operation of the equipment under varying operating conditions must be analyzed since any process is prone to disturbances. This needs a model which captures all interactions. Such a model can be used for nonlinear analysis and to subsequently develop control strategies and optimize plant operation. The steady state and dynamic behavior is predi ....etc

ABSTRACT

VEHICLE HANDLING, STABILITY,AND BIFURCATION ANALYSIS FOR NONLINEAR VEHICLE MODELS

Vehicle handling, stability, and bifurcation of equilibrium conditions were studied
using a state vector approach. The research provided a framework for an
improved method of vehicle handling assessment that included non-linear regions
of performance and transient behavior. Vehicle models under pure lateral slip,
constant velocity, and constant front steer were developed. Four-wheel, two-axle
vehicle models were evolved from si ....etc
