With the Object-Reference (ORef) approach, the traditional object-oriented model is extended with references to act as a canonical model. Our ORef model facilitates the storage of localised behaviour and provides a precise de nition for updating objects across distributed information systems. Both these characteristics are realised using an Object Pool connectivity mechanism that connects local...

Smeared link fermionic actions can be straightforwardly simulated with partial-global updating. The efficiency of this simulation is greatly increased if the fermionic matrix is written as a product of several near-identical terms. Such a break-up can be achieved using polynomial approximations for the fermionic matrix. In this paper we will focus on methods of determining the optimum polynomials.

When a mobile robot uses vision for self-localization and obstacle avoidance, the results of image processing become available after a variable computational delay. If the robot keeps moving during image processing, results become available after the robot has left the position where the image was taken. This is the problem of control in presence of intermittent delayed feedback. This paper pro...

identification of damping parameter is usually more complicated and unreliable comparing to mass or stiffness identification in structural dynamics. there are many factors such as intermolecular friction, coulomb friction and viscous damping affecting the damping mechanisms in a structure. therefore it is difficult, and in some cases impossible, to describe the details of damping mechanisms by ...

This paper presents our efforts in the updating of the Storm Water (SW) Database using Global Positioning System (GPS), direct survey and measurements of the Storm Water structures (or called Manhole) in GIS database management. The main task assignments include (1) Designing a data structure, which becomes an effective geodatabase structure to represent the storm water structures and the corre...
