This paper presented a rigorous mathematical model based on orbital parameters for correction of the geo-rectified images such as Ikonos Geo, where the geometry of image at the time of imaging is lost and minimum information regarding the satellite movement in its orbit is available. Based on this model, the geo-rectified image is converted back to its geometry at the time of imaging at first. ...

tunnelling through cities underlain by soft soil, commonly associated with soil movement around the tunnels and subsequent surface settlement. the predication of ground movement during the tunnelling and optimum support pressure could be based on analytical, empirical or the numerical methods. the commonly used earth pressure balance (epb) tunneling machines, uses the excavated soil in a pressu...

This paper presents a semi-distributed approach, for load balancing in large parallel and distributed systems, which is different from the conventional centralized and fully distributed approaches. The proposed strategy uses a tw<rlevel hierarchical control by partitioning the interconnection structure of a distributed or multiprocessor system into independent symmetric regions (spheres) center...

We survey the results of SPP 1253 project ”Numerical Analysis of State-Constrained Optimal Control Problems for PDEs ”. In the first part, we consider Lavrentiev-type regularization of both distributed and boundary control. In the second part, we present a priori error estimates for elliptic control problems with finite dimensional control space and state-constraints both in finitely many point...

voltage control is one of the imperative issues in the smart distribution control system. while traditional distribution network is equipped with communication and monitoring equipment, the online voltage control can be perfectly achieved. with using these smart grid technologies, the distribution voltage control schemes should carry out intelligently and cover the undesirable effect of high pe...

recently, data collection from seabed by means of underwater wireless sensor networks (uwsn) has attracted considerable attention. autonomous underwater vehicles (auvs) are increasingly used as uwsns in underwater missions. events and environmental parameters in underwater regions have a stochastic nature. the target area must be covered by sensors to observe and report events. a ‘topology cont...

This paper describes a control framework that enables distributed battery energy storage systems (BESS) connected to distribution networks (DNs) track voltage setpoints requested by the transmission system operator (TSO) at specific interconnection points in an optimal and coordinated manner. The design is based on optimisation problem whose objective minimise real-time voltage-tracking mismatc...
