Installation Penalty of Aero-Engines on Narrow Body Aircraft

Decades of improvements of engine efficiency on internal engine components through better materials, design methods and novel fabrication techniques have resulted in fuel consumption reductions. Another major factor for improving engine fuel consumption has been the increase of bypass ratio. However, this has a significant impact on engine...

Design in principle of crane vessel for flexible fully assembled wind turbine installation

Wind turbine industry is growing and future predictions are promising. However, a shortage of installation vessels could influence this growth in offshore wind industry. Commonly, wind turbines are installed in components using a jack-up vessel. Occasionally, wind turbines are installed fully assembled. Lifting above the wind turbine is not...

Experimental identification of the dynamic behaviour of pile-soil system installed by means of three different pile-driving techniques

A novel pile-driving technique, named Gentle Driving of Piles (GDP), that combines axial low-frequency and torsional high-frequency vibrations has been developed and tested recently. During the experimental campaign, several piles were installed onshore, making use of the GDP shaker. Besides those, a number of additional piles were installed...

On the practical use of the Material Point Method for offshore geotechnical applications

The Material Point Method (MPM) has been developed as a special finite element-based method for large deformation analysis, material flow and contact problems. When it comes to applications in soil, MPM can provide solutions where conventional FEM faces its limitations. Examples of geotechnical applications include landslides, silo filling and...

Tangible air: An Interactive Installation for Visualising Audience Engagement

This article presents an end-to-end system for capturing physiological sensor data and visualising it on a real-time graphic dashboard and as part of an art installation. More specifically, it describes an event where the level of engagement of the audience was measured by means of Galvanic Skin Response (GSR) sensors and of the presenter...

ARCS Architectural Chameleon Skin: A swarm-based architectural installation

Traditionally, interactivity in architecture has been suppressed by its materiality. Building structures that can transform and change themselves have been the dream of many architects for centuries. With the continuous advancements in technology and the paradigm shift from mechanics to electronics, this dream is becoming reality. Today, it is...

Geotechnical Monitoring of a Trial Pit Excavation toward the Boom Clay in Antwerp (Belgium)

In order to relieve the busy traffic arteries of Antwerp (Belgium), the closing of the ring around Antwerp was put to study by BAM (Beheersmaatschappij Antwerpen Mobiel). The design of this construction requires detailed insight in the behaviour of the overconsolidated Boom clay layer during and after dewatering and removal of the covering soil...
