This report makes an overview of 2D, 2,5D and 3D approaches for indoor space subdivision for the purpose of indoor navigation. The report starts with a conceptual framework for indoor space utilisation. We introduce and elaborate on the concepts of indoor space (navigable and non-navigable), agent, activity, resource and modifier. Using these...

Because of heavy deposition and water shortage, the Yellow River faces the risk of flooding and no-flow since the middle of 1980s. The problem could be solved only by integrated water management. However, Dutch has a long history fighting the flood and gets a lot of experiences in water management, especially river ecosystem recovered after 1993...

The paper presents a design formula for Tetrapod armour on a 1:1.5 slope exposed to head-on random wave attack The formula predicts the relative number of broken Tetrapods as function of: the mass of the Tetrapods, the concrete tensile strength and the wave height in front of the structure. Thus, the formula addresses the observed problem of...

The RMBFM-Project (Rubble Mound Breakwater Failure Modes) is sponsored by the Directorate General XII of the Commission of the European Communities under the Contract MAS-CT92- 0042, with the objective of contributing to the development of rational methods for the design of rubble mound breakwaters. 11 institutes from the European Union...

The rational design diagram for Dolos armour should incorporate both the hydraulic stability and the structural integrity. The previous tests performed by Aalborg University made available such design diagram for the trunk of Dolos breakwater without superstructures (Burcharth et al 1992). To extend the design diagram to cover Dolos breakwaters...

Using a multiple-scale perturbation method we derive a set of governing equations describing the transformation of long wave and short wave components in a wave group. These equations are derived from Boussinesq equations with the assumption that the length scale of wave group modulation is in the same order of magnitude as that of the bottom...
