Relative state estimation and observability for formation flying satellites in the presence of sensor noise

This paper presents an investigation into the relative state estimation and observability for two formation flying satellites using two different relative navigation sensor sets. The first set consists out of a transmitter antenna on one satellite and a single receiver antenna on the other satellite to measure the inter-satellite range using a...

Strategies for Orchestrating and Managing Supply Chains in Public Service Networks

Joining-up is high on the e-government agenda as this is expected to improve service delivery to citizens and businesses. It requires public and private organizations to cooperate with each other within networks that are formed around public services that cross the boundaries of organizations. Cross-organizational processes in such a network are...

A framework for the study of grid inter-operation mechanisms

The study of the history of computing infrastructures reveals an integration trend. For example, the explosive growth of the Internet in the 1990s was the result of an integration process started in the 1960s with the emerging networks of computers. By using the Internet, millions of users were capable of accessing information anytime and...

All for one: Factors for alignment of inter-dependent business processes at KLM and Schiphol

As airline and hub competition becomes fiercer, airline-airport co-operation becomes a necessary option for both main carrier airlines and hub airports to face this competition together. The inter-dependency between airlines and airports in producing air-transport services is tight, i.e. their destinies are inter-twined. Their existence as...

A Novel Receiver Architecture for Single-Carrier Transmission over Time-Varying Channels

In this paper, we present a single-carrier transceiver for rapidly time-varying channels, where the equalization step is implemented in the frequency domain. When the channel abides with both fast fading and severe inter-block interference, our equalizer relies on a band approximation of the frequencydomain channel matrix to maintain low...

Adaptive corporate environments: Creating real-time interactive spatial systems for corporate offices incorporating computation techniques

Implementing inter-organisational service systems: An approach for emerging networks in volatile contexts

Public organizations in the developing world are undergoing a gradual but irreversible change, due to innovations in information and communications technologies. The emergence of business networks, among such organizations, indicates an increasing interdependence and a search for solutions to regain waning strategic relevance and competitive...

Space and crime in Dutch built environments: Macro and micro scale spatial conditions for residential burglaries and thefts from cars

At this moment, more knowledge is available on the physical characteristics of the built environment and their relationship to criminal opportunity rather than the spatial characteristics of potential targets and the public and private space between them. To improve this situation, a research project was started in the Dutch cities Gouda and...

Kinematics and Directionality of Waves in the Surf Zone

Realistic modelling of the internal kinematics of wind waves breaking on a beach is of great practical importance, e.g. for the modelling of coastal processes and for the design of coastal structures. A fundarnental aspect in this modelling concerns. the relation between the surface elevation and the internal kinematics. In this respect it...
