This paper deals with an analysis of performances of the HL (Hyperloop) transport system considered as an advanced transport alternative to the existing APT (Air Passenger Transport) and HSR (High Speed Rail) systems. The considered performances are operational, financial, social and environmental. The operational performance include capacity...

To advance ATM research as a science, ATM research results should be made more comparable. A possible way to do this is to share tools and data. This paper presents a project that investigates the feasibility of a fully open-source and open-data approach to air traffic simulation. Here, the first of the two main challenges is to achieve a high...

Softening at drinking water treatment plants is often realised by fluidised bed pellet reactors. Generally, sand is used as seeding material and pellets are produced as a by-product. To improve to sustainability, research has been carried out to replace the seeding material by re-using grained and sieved calcite pellets as seeding material. An...

Concrete structures are commonly cracked when in service. To overcome issues arising from cracking, self-healing concrete is being developed. Together with the development of the material, techniques to verify and quantify self-healing are being developed. A number of destructive techniques have been used in the past. It would be beneficial to...

In practice, drinking water technologists use simplified calculation methods for aquatic chemistry calculations. Recently, the database stimela.dat is developed especially for aquatic chemistry for drinking water treatment processes. The database is used in PHREEQC, the standard in geohydrology for calculating chemical equilibria in groundwater....

This paper presents the application of the open source non-hydrostatic wave-flow model SWASH to propagation of irregular waves in a barred surf zone, and the model results are discussed by comparing against an extensive laboratory data set. This study focus not only on wave transformation in the surf zone, but also on the numerical prediction of...

Research in support of indoor mapping and modelling (IMM) has been active for over thirty years. This research has come in the form of As-Built surveys, Data structuring, Visualisation techniques, Navigation models and so forth. Much of this research is founded on advancements in photogrammetry, computer vision and image analysis, computer...

A long-lasting barrier protection at damaged sites of coated system can be achieved by means of an active response of the primer. This may be attained through the release of reactive liquids from dispersed containers, the increase of the local mobility of the polymeric network, or the expansion of (dispersed elements in) the primer [1]. Such...

The work described in this paper aims at developing the interrelation and overall effects of interaction between a folded plate roof structure and a system of branching column supports. In the context of architectural performance it is of interest to discuss the effects of the material on environmental conditions. The current study is...

In February 2008, FIG submitted the Land Administration Domain Model (LADM) to the International Organization for Standardization (ISO). After three meetings with the LADM/ISO19152 Project Team (in Copenhagen, Denmark, May 2008; in Delft, The Netherlands, September 2008; and in Tsukuba, Japan, December 2008) we are now preparing a Committee...

The aim of this paper is to develop a method for describing urban patter by means of simple mathematical calculations applicable for urban design. Two approaches were used and combined with one another. The first approach was Stephen Marshall’s method for calculating T-junctions and X-junctions seen in relationship with a cul-de-sac and network...

The aim of this paper is twofold. Firstly, it discusses how to analyse entire regions with the help of space syntax. Secondly, it demonstrates how a main route network through and between urban areas can be calculated in Depthmap. For this purpose one can combine angular choice with metrical distance and add various radiuses on top of each other...

Modelling is of substantial use in policy analysis. Since policy analysis tries to facilitate decision making of complex multi-actor problems under uncertain circumstances, it needs to rationalize and simplify reality. This is the major challenge of doing policy analysis and especially modelling. The model as an abstract representation of the...

Worldwide, aquatic vegetation is important for the physical and ecological condition of coastal areas. Unfortunately, this vegetation (e.g. seagrasses) is also under pressure due to human activities. Protection and restoration are cumbersome, particularly because the complex relations between vegetation and its environment are not yet well...
