Drivers continuously adapt to the different needs and constraints in the driving scene. Literature has provided evidence for two adaptation strategies in response to an increased risk (decreasing the road width or increasing the driving speed) while lane keeping: decreasing driving speed and increasing endpoint arm stiffness. However, so far...

Within this research parcel behaviour over a bidirectional sorter is optimized to increase efficiency. Currently, influence of parcel properties on the sortation behaviour is unknown and equipment settings are set by experience rather than objective information. To gain insight in the behaviour first, a simulation model has been developed and...

Bulk handling grabs wear due to interaction with bulk material. In this research the geometrical shape of the grab is adjusted to reduce this wear. A DEM simulation using an iron ore pellet material model, created by S. Lommen, is used to assess different concepts. The material model is validated for forces, but not for wear. Wear measurements...

The upper reservoir intervals of the Lower Jurassic Åre Formation in the Heidrun Field (Offshore mid-Norway) are very heterolithic and have the lowest oil recovery factor of the field despite significant amounts of remaining reserves. One of these reservoir zones is the formation Åre 6.2, which is mainly composed of tide-dominated heterolithic...

In today's world, the Internet is the backbone of our society. The relatively unknown Border Gateway Protocol (BGP), and with its vulnerabilities, gives malicious parties an opportunity for abuse. By improving the currently known AS relation data set and by simulating BGP traffic this abuse is better spotted. Kastelein's topology generating...

Pipeline networks are extensively used in the oil and gas industry to transport fluids under multiphase flow conditions from the wells to the production platforms or plants. Over time, the flow rate of the production fluid decreases as the reservoir pressure decreases. When the flow rate decreases to below a certain value, unstable flow with...

Compositional flow simulation is the best practise to model the complex enhanced oil recovery process. This involves solving highly coupled and non linear flow, transport equations.<br/>Interaction of components within different phases and the fluid interaction with rock properties makes it difficult to accurately predict the natural flow...

Range verification based on prompt gamma detection is an important step to improve dose control for proton therapy. To deduce the proton range from the detected prompt gamma emission, a prediction of the measured profile is required. This study introduces the Boltzmann solver as a faster alternative to the Monte Carlo simulations to produce dose...

As the margins for improvements in the current freight transport system become limited, researchers address more and more the importance of collaboration between the actors which is crucial for the implementation of new, more efficient transport concepts as synchromodality. In addition, rail is concerned as a sustainable mode of transport that...

Intermodal Inland Waterways Transportation (IIWT) has been the first alternative to reduce the dependency on road transportation in the Netherlands. However, with the growth of freight shipping demand, several problems have been faced by IIWT: small size barge’s congestion and insufficiency of inland terminal handling’s capacity. The idea to...

Geothermal energy is a relatively sustainable energy source of which the essence is to extract heat from hot subsurface rocks. Circulating fluids serve as the transport agent of heat. The contact area between the fluids and the rocks is where the relevant heat transfer occurs, i.e., where the water is heated up. In some geothermal reservoirs,...

Ride comfort is one of the aspects of vehicles that manufacturers are constantly trying to improve, and seat vibration is an important contributing factor to ride comfort. The present study developed a seat vibration simulator for investigating the human perception of seat vibration and its application on ride comfort evaluation. <br/><br/>The...

Decrease in oil prices have negatively affected the investment towards offshore oil and gas explorations. This has in turn compelled offshore structure fabricators to find cost effective ways of fabricating oil platforms and jackets, to stay competitive in the industry. In this research paper, three alternative configurations to the conventional...

Laminar-turbulent transition (LTT) is the process through which smooth laminar flow transits into chaotic turbulent flow. Investigation of the paths taken to transit into turbulence is a front-runner among other methods followed to characterise turbulent flows. This is of particular importance in aerospace and energy industries for the design of...

Current unmanned aerial vehicles (UAVs) are limited in operating altitude and endurance by the maximum attainable performance of small gas turbine engines. While improvements in the cycle thermal efficiency can be obtained through the introduction of heat exchangers, the consequent increase in engine weight partially offsets the benefits gained...

MapReduce ecosystems are (still) widely popular for big data processing in data centers. To address the diverse non-functional requirements arising from many and increasingly more sophisticated users, the community has developed many scheduling policies for MapReduce workloads. Although some individual policies can dynamically optimize for...

Research in the motorcycle industry is lagging behind research in the automotive industry. Especially with respect to safety, more research is needed, since motorcycles are overrepresented in the number of road casualties and injuries. Important tools in vehicle research are vehicle simulators. The use of motorcycle simulators enables...

Even though negative effects on the use of crude oil have surfaced over the past years, our energy matrix still largely relies on this energy source. The production of oil, therefore, plays an important role in our society. Unfortunately, the process of oil production is highly uncertain. There are uncertainties associated on the production...

We present a novel nonlinear formulation for modeling reactive-compositional flow and transport in presence of complex phase behavior due to combination of thermodynamic and chemical equilibrium in multi-phase systems. We apply this formulation to model precipitation/dissolution of minerals in reactive flow in subsurface reservoirs. The proposed...
