Transition zones in railway tracks are locations with considerable changes in the vertical stiffness of the rail support. Typically they are located near engineering structures, such as bridges, culverts, tunnels and level crossings. In such locations, the differential settlement always exists and continually grows without proper maintenance....

The works [Volodymyr et al. Playing atari with deep reinforcement learning. arXiv preprint arXiv:1312.5602, 2013.] and [Volodymyr et al. Human-level control through deep reinforcement learning. Nature, 518(7540):529–533, 2015.] have demonstrated the power of combining deep neural networks with Watkins Q learning. They introduce deep Q networks ...

In the dynamic domain of motorsport, the most agile is naturally the victor. A race car can only be as efficient as the systems that control it and here lies the importance of automotive embedded systems which offer precise and quick control over the mechanics of the race car. The Gearbox Control Unit (GCU) for the Paddle-shift System is one...

In order to cope with various supplies and loads in an autonomous microgrid, a system of sensors and a control unit was developed. The goals of this system are to cope efficiently in the event of an energy supply shortage, and to prevent such events as much as possible. To achieve these goals, the aim was to manage energy in the system as...

In the wake of several dramatic incidents where cargo ships were lost at sea due to corrosion related structural failure, spilling large amounts of oil, the regulations regarding corrosion preventions have been tightened. Specifically regulations regarding painting and painted surfaces in a ship’s sea water ballast tanks are stricter than ever...

A concurrent multi-scale computational strategy for rail surface crack initiation analysis is introduced in current paper. It attempts to take advantage of the efficiency of macroscopic models and the accuracy of the mesoscopic models. The solving procedure is, through the coupling of individual approaches, beginning from the largest scale to...

Accidents, malfunctioning matrix signs, oil on the road and a bridge that is not able to close are examples of traffic events that happen every day on the Dutch roads. In the Netherlands we are able to measure traffic speeds and calculate travel times on highways and most important secondary roads using a network of connected traffic measuring...

This paper presents a proof of concept study into a computational strategy for reusing structural stadium elements. The strategy goal is overcoming the reuse design strain through implementation of a genetic algorithm. This algorithm is calibrated to search for a structural frame configuration, while using a reusable element set, meeting floor...

The Non-Centralized Model Predictive Control (NC-MPC) framework refers in this paper to any distributed, hierarchical, or decentralized model predictive controller (or a combination of them) the structure of which can change over time and the control actions of which are not obtained based on a centralized computation. Within this framework, we...

At this point in time, 3D-printing techniques in general, but especially applied for the building industry, still are in a phase of early experiments. One of the experimental attempts is to print a full-scale, three-story high, house in Amsterdam, using an up scaled version of a FDM-printer that is able to print blocks of 1.8 x 1.8 x 3.0 meters...

Currently, in the conceptual envelope design of sports facilities, multiple engineering performance feedbacks (e.g. daylight, energy and structural performance) are expected to assist architectural design decision-making. In general, it is known as Building Performance Optimization in the conceptual architectural design phase. Essentially, it...

The thesis looked into sequences of niche strategies within the automotive industry. Using an exploratory multiple-case study research design, three technologies were investigated: dual-clutch transmission (DCT), anti-lock brakes (ABS), and polymer exchange membrane fuel cell vehicle (PEMFCV). The concepts of 'niche strategy' and 'sequence of...

Within technological R&D companies, the decisions made within their Strategic Technology Planning (STP) process are of great importance due to their financial, legal and competitive repercussions. For this reason their R&D managers want to be as widely informed as possible about the risks and benefits of developing a certain technology. As the...

Focusing on large span structures for sport buildings, the paper tackles the role of parametric modelling and performance simulations, to enhance the integration between architectural and engineering design. The general approach contrasts post-engineering processes. In post-engineering, technical performances are considered in late stages of...

A solar updraft tower is a type of power plant which uses solar irradiation to generate electricity. It consists of three elements: a solar air collector, wind turbines and a chimney. The proposed concepts for this chimney schematise it as a 1-km-tall reinforced concrete shell, which are vulnerable to resonance induced by storm actions. This...

The adoption of computation in the building industry has led to the development of a range of tools intended for design. Although commonly used for detailed analysis (FEA) and documentation (CAD/BIM), few tools address the needs of the early design stages for flexibility and quick, insightful feedback and documenting the justification of design...

A composite textile reinforced concrete (TRC) material is developed to overcome the difficulties of constructing double-curved freeform structures. This is possible by shear-deformation of the woven reinforcement. It affects the direction of reinforcement and thickness, resulting in variable orthotropic properties over the surface. The research...

Big wind farms with big wind turbines are more cost effective and produce greener electricity compared to smaller ones. This is one of the reasons for the growth of wind turbine size during the last 3 decades. However, as wind turbines become bigger, their blades become longer, thicker and heavier. This results in larger unsteady loads on blades...

The production of architectural elements with complex geometry is challenging for concrete manufacturers. Computer-numerically-controlled (CNC) milled foam moulds have been applied frequently in the last decades, resulting in good aesthetical performance. However, still the costs are high and a large volume of waste is produced. This paper...

We demonstrate thermo-mechanical relaxation oscillations in a strongly driven quartz crystal. Dynamic bifurcation leads to two stable oscillation states with a distinct electrical impedance. Slow Joule-heating, which shifts the susceptibility of the crystal, provides a feedback that leads to thermally induced oscillations in which the amplitude...
