The decision of selecting the right product from market is getting tedious these days from customers point of view, as firms offering product at low cost do not provide the assurance that the product will work as desired by the consumer whereas companies providing good quality products sell their product at relatively high prices. As a customer, a person looks around for a product which is low in...
This paper presents a new approach to a fuel-optimal impulsive control problem of the guided projectile by using an improved particle swarm optimization technique. The problem is interpreted by using optimal control theory resulting in the formulation of minimum-fuel impulse control problem. The formulation entails nonlinear, 3-dimensional projectile flight dynamics, boundary conditions and discontinuous...
The selection of Chinese rural land requisition path plays a crucial role on whether social benefits occurred by land requisition could be maximized. In this paper the dynamic optimization problem of land requisition is aimed at by the government. A dynamic analysis method is utilized through Optimal Control Theory. The dynamic optimization model is established with no budget-constraining then its...
Superconducting nanoelectrical circuits are promising candidates for the physical implementation of the basic building block of a quantum computer, the qubit. We investigate how optimal control theory can be applied to optimize the dynamics of Josephson qubits. For the example of the charge qubit, several numerical methods are employed to search for external control fields which, by current technology,...
Peer-assisted Video-on-Demand (VoD) systems have not only received substantial recent research attention, but also been implemented and deployed with success in large-scale real- world streaming systems, such as PPLive. Peer-assisted Video- on-Demand systems are designed to take full advantage of peer upload bandwidth contributions with a cache on each peer. Since the size of such a cache on each...
Network Utility Maximization (NUM) techniques, which cast resource sharing problems as one of distributed utility maximization, have been investigated for a variety of optimization problems in wireless and wired networks. Our recent work has extended the NUM framework to consider the case of resource sharing by multiple competing missions in a military-centric wireless sensor network (WSN) environment...
Hybrid vehicles use two energy sources for their propelling. Usually an internal combustion engine (ICE) is used with one or more electric machine(s) (EM). The problem is then to split the driver power demand between the ICE and the EM in order to minimize a criterion, usually the fuel consumption. A global optimization algorithm based on optimal control theory is recalled. The obtained results are...
