    Description: "What can we learn about the development of public interaction in e-democracy from a drama delivered by mobile headphones to an audience standing around a shopping center in a Stockholm suburb? In democratic societies there is widespread acknowledgment of the need to incorporate citizens’ input in decision-making processes in more or less structured ways. But participatory decision making is balancing on the borders of inclusion, structure, precision and accuracy. To simply enable more participation will not yield enhanced democracy, and there is a clear need for more elaborated elicitation and decision analytical tools. This rigorous and thought-provoking volume draws on a stimulating variety of international case studies, from flood risk management in the Red River Delta of Vietnam, to the consideration of alternatives to gold mining in Roșia Montană in Transylvania, to the application of multi-criteria decision analysis in evaluating the impact of e-learning opportunities at Uganda's Makerere University. Editors Love Ekenberg (senior research scholar, International Institute for Applied Systems Analysis [IIASA], Laxenburg, professor of Computer and Systems Sciences, Stockholm University), Karin Hansson (artist and research fellow, Department of Computer and Systems Sciences, Stockholm University), Mats Danielson (vice president and professor of Computer and Systems Sciences, Stockholm University, affiliate researcher, IIASA) and Göran Cars (professor of Societal Planning and Environment, Royal Institute of Technology, Stockholm) draw innovative collaborations between mathematics, social science, and the arts. They develop new problem formulations and solutions, with the aim of carrying decisions from agenda setting and problem awareness through to feasible courses of action by setting objectives, alternative generation, consequence assessments, and trade-off clarifications. As a result, this book is important new reading for decision makers in government, public administration and urban planning, as well as students and researchers in the fields of participatory democracy, urban planning, social policy, communication design, participatory art, decision theory, risk analysis and computer and systems sciences.

    Description: The correct resolution of the carrier-phase integer ambiguity is a key aspect for centimetre-level precise positioning with Global Navigation Satellite Systems (GNSS). This integer ambiguity resolution (IAR) process enables the adoption of phase observations as ultra-precise pseudo-range measurements, thus leveraging their millimetre-level precision. An effective and rigorous approach to IAR problems has been given by the Least-squares AMBiguity Decorrelation Adjustment (LAMBDA) method, described in Teunissen (1995). In addition to integer estimation and validation, implemented in the open source LAMBDA software, an evaluation of IAR success rate for different estimators has been made possible by the release of a Ps-LAMBDA toolbox.In this work, we describe the LAMBDA 4.0 toolbox, which has recently been developed by the GNSS research group at TU Delft. This toolbox merges the LAMBDA 3.0 (2012) and Ps-LAMBDA 1.0 (2013) functionalities into a single framework, where new different estimators are implemented, e.g. Vectorial Integer Bootstrapping (VIB), Integer Aperture Bootstrapping (IAB) and Best Integer Equivariant (BIE) solutions. Moreover, different algorithm modifications are introduced for enhanced performances, e.g. in the integer search process, so targeting high dimensional ambiguity resolution (HDAR) problems, which are foreseen to become more and more important in the future years. This high dimensionality challenge is expected in view of the possible deployment of new satellite mega-constellations in Low Earth Orbit (LEO), with hundreds of satellites being tracked by user receivers. This new LAMBDA 4.0 toolbox will officially be released to the public later this year.
