Flexible gas infrastructures

The Flexible Port

Ports are beset with many uncertainties about their futures. They are confronted with new demands in terms of functions and scales, new external constraints, and changed expectations. The inability to adequately meet these demands can mean costly adaptations for a port, or loss of cargo and competitive position. A plausible reason is that the...

Engineering Flexible and Agile Services: A Reference Architecture for Administrative Processes

To provide up-to-date services towards citizens and businesses, administrative organizations need to make sure their business services and processes and supporting applications are flexible and agile enough to deal with changing situations and ensure legal compliance all the time. The research presented in this dissertation provides a reference...

Evolution of housing

‘Perfection means something is complete and stands still and what stands still doesn’t change or evolve and is automatically dead. Everything in the universe changes, evolution implies that the creation is not complete hence the possibility of evolving’ (Osho, 1985). Our society and economy are constantly changing. Hence the demands and wishes...

Role of Flexibility in Sustainable Port Development

Sustainability has become a high profile objective in all aspects of our lives, including the development of our infrastructures. Flexibility can enhance sustainability endeavors, yet its contribution is not clear to most. In this paper we investigate the role of flexibility in sustainable port development in order to promote its incorporation...

Flexibility in port infrastructure

The present volatile environment continues to place new functional requirements on port infrastructure. As a result, the useful life of port infrastructure has reduced in recent years. Flexibility in infrastructure makes it possible to adapt them for new or changed use. The use of flexible and sustainable solutions infrastructures needs to be...

Flexibility in Port Planning and Design

Recently, flexibility has received much attention from port researchers, designers, and managers. This is because the stability of the competitive environment of the past has been replaced by increasing uncertainty. The current economic crisis and the recent trends in ports and shipping sectors are causing port planners to rethink their approach...

Conflicting flexibility

New buildings are designed for first users. For a sustainable approach there are many advantages in designing in flexibility and adjustability in order to enable and facilitate the other sequential users. For the first investor this flexibility is translated into improved exit values due to increased potential. The second investor is acquiring a...

Effect of chain flexibility in the network structure on the viscoelasticity of epoxy thermosets

In this paper a detailed study in investigating the effect of the chain flexibility in epoxy-amine crosslinked network is done. In order to introduce flexibility into the crosslinked network a homologous series of four aliphatic diamine curing agents varying only in the chain length and having a constant functionality (f?=?4) is taken and cured...

Which standards’ characteristics increase system flexibility? Comparing ICT and Batch Processing Infrastructures

Most large Information and Communication Technology (ICT) systems develop in a piece-meal fashion. Their complexity and evolution is difficult to manage. They lack flexibility. This contrasts sharply with system design in the batch-wise processing industry, where flexibility has always had a high priority. In this industry, the S88 standard...

Force-directed design of a voluntary closing hand prosthesis

This paper presents the design of a body-powered voluntary closing prosthetic hand. It is argued that the movement of the fingers before establishing a grip is much less relevant for good control of the object held than the distribution of forces once the object has been contacted. Based on this notion, the configurations of forces on the...

Equivalent flexibility modelling: A novel approach towards recursive simulation of flexible spacecraft-manipulator dynamics

For the simulation of rigid spacecraft manipulator dynamics there exists efficient recursive software. Extension of this software for the simulation of flexible spacecraft-manipulator dynamics would have important advantages. In this paper the method of Equivalent Flexibility Modelling (EFM) is outlined. Each flexible body is re-modelled as a...

A reference model for the dynamics of a flexible, spacecraft-based manipulator

The objective of the study is to develop the equations of motion of a single link, flexible manipulator, attached to an orbiting spacecraft. A payload may be attached to the end-effector of the manipulator. Starting point is d'Alembert's principle, with displacements described by hybrid coordinates. The equations of motion for the two-body...
