The purpose of this paper is to investigate the highly complex interaction between turbulent flow and deep-sea marina structure using a commercial CFD code (FLUENT 6.2) with Large Eddy Simulation (LES) approach. A series of three-dimensional LES of wake flows past overlapping cylinder of finite height are carried out with a range of Reynolds...

This paper reports the results from a turbulent numerical modelling study on the free overfall in a rectangular channel. A wide range of model parameters (i.e. discrete square bar bed roughness, channel slope, and incoming upstream Froude number) is investigated. The water surface profiles, velocity fields and end-depth are simulated and...

Systems Engineering (SE) and Multidisciplinary Design Optimization (MDO) are usually regarded as two different aspects of spacecraft design. This paper investigates the problem of merging these two fields for the improvement of the spacecraft system design. The SE and MDO processes are described with emphases on their principles, models and...

Challenges and opportunities of wireless sensor networks (WSNs) in space applications are presented. The investigation of internet protocols, ad hoc routing and commercial-off-the-shelf (COTS) wireless communication protocols for efficient and reliable network design is addressed. In order to facilitate the analysis, several application...

The problem of new attributes and the induced uncertainties has been extensively discussed in this paper. The methodology of uncertainty multidisciplinary design optimization has also been extended to spacecraft conceptual design in the presence of new attributes. The application of this methodology on fractionated spacecraft indicates that the...

In this paper, we exploit the advantages of tensor representations and propose a Supervised Multilinear Learning Model for regression. The model is based on the Canonical (CAN-DECOMP)/Parallel Factors (PARAFAC) decomposition of tensors of multiple modes and allows the simultaneous projection of an input tensor to more than one discriminative...

Precise formation flying (PFF) missions require formation acquisition and maintenance through interactions among spacecraft by inter-satellite communication and relative navigation. That requires the network architecture to satisfy dedicated system constraints of time-criticality for updating navigation measurements and flexibility for...

With the increasing urban population, and the urban exploitation and utilization, especially in the subsurface and the air, various spaces above and below each other are built and belonging to different owners or users. Although the traditional 2D cadastre still plays a dominant role in land administration, urban resource and space management,...

In this paper the design and development of a prototype 3D Cadastral system will be presented. The key aspects of this system are that the model is based on Land Administration Domain Model (LADM) and that the spatial profile is based on a full 3D topological structure. The prototype development starts with profiling the LADM (selecting relevant...

A rapid urban growth in China urges to extend land use to land space use in three dimensions due to limited land resource in cities. 3D cadastre is emerging as an effective means to support such a demands for using urban land in a way of three dimensions. Shenzhen, located in the south-eastern coastal region of China, as one of the most...
