The growth in container volumes over the last decades means an increase in container handling at terminals around the world. Notwithstanding the economic benefits, container handling causes additional pressure on the surrounding infrastructure and the environment. This is happening precisely at a time when environmental issues, in particular CO2...

Copper foil was anodized in 1 M KOH at potentials ranging from −400 to −100 mV vs. Ag|AgCl electrode. Cyclic voltammetry showed a distinct peak with a maximum at around −150 mV. For anodizing at −100 and −200 mV, nanowires with diameters of ca. 19 and 24 nm respectively were found to be grown. Moreover, photoluminescence and X-ray diffraction...

Project-based organizations collect lessons learned in order to improve the performance of projects. They aim to repeat successes by using positive lessons learned, and to avoid repeating negative experiences by using negative lessons learned. Cooke-Davies (2002) claimed that the ability to learn from past projects for future projects is a key...

The vision of intelligent vehicles traveling in road networks has prompted numerous concepts to control future traffic flow, one of which is the in-vehicle actuation of traffic control commands. The key of this concept is using intelligent vehicles as actuators for traffic control systems. Under this concept, we design and test a control...

Needle insertion procedures are commonly performed in current clinical practice for diagnostic and therapeutic purposes. Although prevailing technology allows accurate localization of lesions, they cannot yet be precisely targeted. Needle steering is a promising technique to overcome this challenge. In this paper, we describe the development...

Safety is frequently addressed as an emergent property of complex and dynamic systems. This contribution advocates the validity and importance of incorporating intrinsic technological hazards and systemic interrelations from a multi-actor perspective in the early phases of design and development. This perspective creates inherent properties in...

Advances in additive manufacturing (AM) allow economical production of components with unprecedented geometric complexity. This offers exciting opportunities for innovative designs, and particularly topology optimization has been identified as a key technique to fully exploit the capabilities of AM. However, also AM involves manufacturing...

Gyroscopic actuation is appealing for wearable applications due to its ability to impart free moments on a body without exoskeletal structures on the joints.We recently proposed an unobtrusive balancing aid consisting of multiple parallelmounted control moment gyroscopes (CMGs) contained within a backpack-like orthopedic corset. Using...

In this work, we have incorporated heaters in a MEMS device, which allow the in situ local heating of its contacting surfaces. This design offers a promising solution for MEMS devices with contacting components by preventing capillary-induced adhesion. The force of adhesion was assessed by optically measuring in-plane snap-off displacements. We...

In this study a novel structure for time-delay MIMO systems controller design is introduced. In this method decoupled Smith predictor (SP) controller is designed using Internal Model Control structure (IMC). In order to approximate decoupled system, step response model approximation is employed and simulated on MIMO multiple time-delay system....

Optimization of a single slotted flap with dropped hinge is performed with the objective of increasing the payload of a propeller driven 4-seater general aviation aircraft. Within the optimization loop, two-dimensional aerodynamic characteristics are evaluated using the MSES code, while three-dimensional aerodynamic characteristics and weight...

In this paper we address a preliminary assessment of the performance effects of swirl recovery vanes (SRVs) in a installed and uninstalled tractor propeller arrangement. A numerical analysis was performed on a propeller and a propeller-wing configuration after the SRVs were optimized first in a separate process. The SRVs are essentially...

Designing transient thermal mechanical systems is a challenging task. Material can have many different functions: it can provide heat capacity, heat conduction, mechanical stiffness or even function as an actuator. Topology optimization can provide the engineer with valuable insight on such a problem. One of the most popular topology...

This article presents an evolutionary topology optimization method for mean compliance minimization of structures under design-dependent viscous fluid flow loads. The structural domain is governed by the elasticity equation and the fluid by the incompressible Stokes flow equations. When the modelling of a system consists in the interaction of...

This paper presents a proposal to employ the design computing methodology proposed as StructuralComponents (Rolvink et al [6] and van de Weerd et al [7]) as a method to perform a digital verification process to fulfil the requirements related to structural design and engineering as part of a building design. In current design and engineering...

Future air traffic concepts foresee that in unmanaged airspace, to reduce workload of air traffic controllers and the resulting constraints on capacity, the separation task will be delegated to the flight deck. Technology-driven pilot self-separation support systems have been developed that present explicit automated solutions to deal with...

The advent of automation in the cockpit has greatly affected the nature of the tasks on the flight deck, as well as requirements on the flight crew. Although the introduction of automation in aircraft undeniably improved performance and safety, it also increased complexity in the cockpit. In addition to knowledge of basic flight information,...

Decision making in the tender phase of large infrastructural projects is a complex task for contractors as they have to make design decisions with long term effects and based on complex client requirements. Further complexity is added by the constrained environment of a tender and the uncertainty of winning the tender. As the context and the...
