Autonomous Underwater Vehicles (AUV's) provide an important means for collecting detailed scientific information from the ocean depths. The hull resistance of an AUV is an important factor in determining the power requirements and range of the vehicle. This paper describes a design method using Computational Fluid Dynamics (CFD) for determining the hull(More)
Cache access latency and efficient usage of on-chip capacity are critical factors that affect the performance of the chip multiprocessor (CMP) architecture. In this paper, we propose a SPS2 cache architecture and cache coherence protocol for snooping-based CMP, in which each processor has both private and shared L2 cache to balance latency and capacity. Our(More)
Human head models for the forward computation of EEG using FEM require a large set of elements to represent the head geometry accurately. Anatomically, the electrical property of each element is different, even though they may represent the same type of tissue (white matter, grey matter, etc.). Since it is impossible to obtain the electrical properties of(More)
This paper presents a path planner for rendezvous of multiple autonomous underwater vehicles (AUVs) in turbulent, cluttered, and uncertain environments. The proposed strategy combines an Optimized Mass-center rendezvous point selection scheme with an evolutionary path planner to find trajectories for multiple AUVs with minimal time usage over all(More)
This paper presents a new algorithm for modelling the behaviour of dynamic video. The PDP (Projected Difference Pattern) is designed to perform simple spatiotemporal processing with a strong focus on efficiency of real-time implementation. In its simplest implementation, the algorithm is shown to be suitable for generating dynamic background models, motion(More)
