Backcasting: looking back from a desirable future. Since the 1990s sustainable futures have been explored in backcasting experiments, numerous stakeholders have been involved and first steps have been planned in line with the envisioned sustainable futures. But what is the impact of these so-called backcasting experiments ten years later?

The research presented in this thesis introduces TrAcEs and FoRcEs as control-software design methods to model autonomous traffic agents using shared infrastructures. This method is supported by a workbench that provides software components which facilitate rapid development of safe, exible, agile, and scalable, traffic control systems in a modern programming language.

Terwijl alom maakbaarheid van de samenleving als een achterhaald denkbeeld wordt beschouwd lijkt maakbaarheid van 'nieuw leven' dichterbij te komen. Vragen aangaande 'mensverbetering' worden in dit verband al gesteld. In dit boek wordt dit proces verhelderd en wordt een mogelijkheid aangereikt voor fundamentele kritiek op het aan de ontwikkelingen ten grondslag liggende 'gesloten' wetenschappelijke denken.

In this thesis we have developed a new dynamic O-D matrix estimator that is founded on a behavioural basis. This estimator is able to produce a statistically sound timedependent OD trip table estimate given flow observations and an apriori trip table, such that the estimated dynamic OD flows are consistent with dynamic assignment predictions of network flows based on the estimated dynamic OD table.

Modern physics lacks a unitary theory that applies to all four fundamental interactions. This monograph is a proposal for a single, complete, and coherent scheme of mathematically formulated elementary laws of nature.

The purpose of this book is to provide insight into those elements of acoustics and aeronautics that are connected directly with the problem of aviation noise. It is intended as a textbook for a university course on aviation acoustics at an undergraduate level. The simplicity of presentation also lends itself to the book’s use as an instrument of self-study for the practicing of engineer.

The scientific advances made in the last two centuries have drastically improved the quality and structure of human existence. Exploring the history of that technological progress, and the numerous and complex elements that propelled its development, the Encyclopedia of Technological Progress attempts to comprehensively classify the theories and hypotheses proposed in modern human history on the effects, meaning, and control of these advances.

For the development of autonomously working systems, low-cost and small-size sensors are required to provide the system with information from the environment. Therefore these sensors are often integrated on-chip. This thesis describes different through-wafer interconnect methods, intended to be applicable to most sensors and actuator devices.

Innovatie is een onzeker en vaak langdurig proces. Een goed idee in het heden betekent niet automatisch een goed idee in de toekomst, wanneer markt, technologie en maatschappij zijn veranderd. Daarom dienen futurologen meer dan één visie van de toekomst te hebben.
