Visser, P.N.A.M. (author), Sneeuw, N. (author), Gerlach, C. (author)A fast iterative method for gravity field determination from low Earth satellite orbit coordinates has been developed and implemented successfully. The method is based on energy conservation and avoids problems related to orbit dynamics and initial state. In addition, the particular geometry of a repeat orbit is exploited by using a very...journal article 2003

Blaas, J. (author), Botha, C.P. (author), Post, F.H. (author)Parallel coordinate plots (PCPs) are commonly used in information visualization to provide insight into multi-variate data. These plots help to spot correlations between variables. PCPs have been successfully applied to unstructured datasets up to a few millions of points. In this paper, we present techniques to enhance the usability of PCPs for...journal article 2008

Klievink, B. (author), Janssen, M. (author)Joining up remains a high priority on the e-government agenda and requires extensive transformation. Stage models are predictable patterns which exist in the growth of organizations and unfold as discrete time periods that result in discontinuity and can help e-government development towards joined-up government. Although stage models may be...journal article 2009

(author)Bacteria and archaea import molybdenum and tungsten from the environment in the form of the oxyanions molybdate (MoO4 2?) and tungstate (WO4 2?). These substrates are captured by an external, high-affinity binding protein, and delivered to ATP binding cassette transporters, which move them across the cell membrane. We have recently reported a...journal article 2009

Ter Mors, A.W. (author), Yadati, C. (author), Witteveen, C. (author), Zhang, Y. (author)We consider a multi-agent planning problem as a set of activities that has to be planned by several autonomous agents. In general, due to the possible dependencies between the agents’ activities or interactions during execution of those activities, allowing agents to plan individually may lead to a very inefficient or even infeasible solution to...journal article 2009

Janssen, M. (author), Lee, J. (author), Bharosa, N. (author), Cresswell, A. (author)Multi-agency disaster management requires collaboration among geographically distributed public and private organizations to enable a rapid and effective response to an unexpected event. Many disaster management systems often lack the capability to cope with the complexity and uncertainty. In this introduction to the special issues on advances...journal article 2009

Bharosa, N. (author), Lee, J. (author), Janssen, M. (author)Although various scholars have researched issues regarding disaster management, few have studied the sharing and coordinating of information during disasters. Not much empirical data is available in this field and there is sparse insight into the factors that may impede or facilitate information sharing and coordination among stakeholders. In...journal article 2009

Frijlink, M. (author), Wapenaar, C.P.A. (author)One-way wave equations conveniently describe wave propagation in media with discontinuous and/or rapid variations in one direction, but with smooth and slow variations in the complementary transverse directions. In the past, reciprocity theorems have been developed in terms of one-way wave fields. The boundaries of the integration volumes and...journal article 2010

Bayerl, P.S. (author), Lauche, K. (author)For highly interdependent yet location-specific tasks, distributed teams need to closely coordinate activities and processes. This field study in the upstream oil and gas industry focused on challenges in the coordination of highly interdependent tasks if teams work remotely on an ongoing basis. Based on 78 semi-structured interviews and...journal article 2010

Corman, F. (author), D'Ariano, A. (author), Pacciarelli, D. (author), Pranzo, M. (author)Railway dispatchers are in charge of rescheduling trains during operations in order to limit propagation of disturbances occurring in real-time. To help the dispatchers in such task, an advanced decision support system, ROMA (Railway traffic Optimization by Means of Alternative graphs), has been recently implemented to optimize railway traffic...journal article 2010

Khodabandeh, A. (author), Amiri-Simkooei, A.R. (author), Sharifi, M.A. (author)The efficacy of robust M-estimators is a well-known issue when dealing with observational blunders. When the number of observations is considerably large—long time series for instance—one can take advantage of the asymptotic normality of the M-estimation and compute reasonable estimates for the unknown parameters of interest. A few leading M...journal article 2011
