Sediment of different size are transported in rivers under the action of flow. The first and still most popular sediment continuity model able to deal with mixed sediment is the so-called active layer model proposed by Hirano (1971, 1972). In this paper, we consider the one-dimensional hydromorphodynamic model given by the Saint-Venant equations...

A planar magnet for magnetic density separation, comprising an array of pole pieces succeeding in longitudinal direction of a mounting plane, each pole piece having a body extending transversely along the mounting plane with a substantially constant cross section that includes a top segment that is curved to distribute the magnetic field...

Amsterdam Central Station is the second busiest station in The Netherlands. Several bottlenecks in the 125 years old monumental station exist due to present train and pedestrian volumes. Further traffic growth is expected. To understand and quantify the options for redesign, a thorough understanding of the interaction between the core traffic...

Over the last years all train stations in The Netherlands have been equipped with automatic fare collection gates and/or validators. All public transport passengers use a smart card to pay their fare. In this paper we present a monitor for the performance of the pedestrian function of train stations which is based on data from the automatic fare...

In force based models of pedestrian traffic, the relaxation time, ?, is related to the time it takes a pedestrian to adapt its motion to its preferences. An example of this is linear acceleration, but ? is also connected to how the agent adjusts to spatial variations in its preferred velocity, and affects evasive maneuvers. These many roles of ?...

How to evaluate crowd safety in crowded areas is a tough, but important, problem. According to accident-causing theory, uncontrolled release of hazardous energy among overcrowded pedestrians is the basic cause of crowd disaster. Therefore, crowd energy is modeled in this paper, which takes both pedestrian kinetic energy, pedestrian potential...

Research into the influence of groups on pedestrian flow dynamics has been limited. Previous research found that group size influences the walking velocity of pedestrians within the group and as such the capacity the pedestrian infrastructure. This paper's aim is to provide quantitative insights into the influence of group size and composition...

Nonresonant circularly polarized electromagnetic radiation can exert torques on magnetizations by the inverse Faraday effect (IFE). Here, we discuss the enhancement of IFE by spin-orbit interactions. We illustrate the principle by studying a simple generic model system, i.e., the quasi-one-dimensional ring in the presence of linear/cubic Rashba...

Whether pedestrian movements do or do not follow similar patterns as vehicular traffic while experiencing congestion is not entirely understood. Using data gathered during bottleneck experiments under laboratory conditions, the phenomenon of anticipation before entering congestion is studied. This paper provides proof that the movement behavior...

There are few studies investigating crowd dynamics in panic situations. They used measures such as exit flow rate to explore the exit performance in evacuation scenarios. However, there is limited research exploring the relationship of exit flow rate and density behind the exit for panic scenarios. This study presents a macro level analysis to...

Most scientific attention in port studies centres on deep-sea ports, in particular container ports. In our paper, in contrast, we focus our attention on the determining characteristics of inland port performance in a European context, which is up to now an overlooked part in the scientific literature on port development. Based on a large-scale...

In physical model tests there is often a need of preventing stones from moving. This can be achieved by gluing the stones. Applying PBA (Polyurethane Bonded Agregate, e.g. Elastocoast) guarantees no moving stones, a normal permeability and a transportable model.

Haiti was struck by a heavy earthquake in 2010 and international aid poured into the country. News reports in 2011 were not very positive about the results of post-disaster reconstruction: “The relief efforts are only putting Haiti on lifesupport instead of evolving into the next stage of development”. One of the non-governmental organisations ...

Since more than 97% of the water in the world is seawater, desalination technologies have the potential to solve the fresh water crisis. The most used desalination technology nowadays is seawater reverse osmosis (SWRO), where a membrane is used as a physical barrier to separate the salts from the water, using high hydraulic pressure as the...
