Wiegmans, B. (author), Mouter, N. (author), Vanelslander, Thierry (author), Verweij, Stefan (author)The cost-benefit analysis (CBA) is a widely used approach for the appraisal of transport projects, but criticisms on it have led to the development of alternatives such as the BENEFIT approach. This book chapter analyzes three cases of infrastructure investments in port areas in Belgium and the Netherlands, by application of the BENEFIT approach...book chapter 2022

Oudejans, Erik (author)The Delft real-time GNSS single-frequency precise point positioning (RT-SF-PPP) algorithm is extended to include velocity and receiver clock drift as unknown states to be estimated from Global Navigation Satellite Systems (GNSS) measurements. Carrier-phase ambiguities are assumed constant over time. Two different variance models are used, one...master thesis 2021

Ma, H. (author), Psychas, D.V. (author), Xing, Xuhuang (author), Zhao, Qile (author), Verhagen, S. (author), Liu, Xianglin (author)The tropospheric delay is one of many error sources that affect the Global Navigation Satellite System (GNSS) positioning solutions. The widely used troposphere models assume a homogeneous atmosphere so that only the zenith delay needs to be determined and is mapped through an elevation-dependent mapping function. This procedure is to reduce...journal article 2021

Ma, H. (author), Verhagen, S. (author)Precise point positioning (PPP) is one of the well-known applications of Global Navigation Satellite System (GNSS) and provides precise positioning solutions using accurate satellite orbit and clock products. The tropospheric delay due to the neutral atmosphere for microwave signals is one of the main sources of measurement error in PPP. As...journal article 2020

Ma, H. (author), Zhao, Qile (author), Verhagen, S. (author), Psychas, D.V. (author), Liu, Xianglin (author)The benefits of an increased number of global navigation satellite systems (GNSS) in space have been confirmed for the robustness and convergence time of standard precise point positioning (PPP) solutions, as well as improved accuracy when (most of) the ambiguities are fixed. Yet, it is still worthwhile to investigate fast and high-precision...journal article 2020

Švent, Nejc (author)The planning, implementation and operation of large infrastructure projects brings together a range of stakeholders with variously aligned interests and risk perceptions. In project-financed infrastructure, lenders are a specific stakeholder whose risk analyses need to understand a project’s technical substance as a basis for appraising the...master thesis 2019

Zhan, C. (author)Currently, more and more people live in cities, and this leads to an enormous increase in global GHG emissions. Cities are blamed for the cause of environmental problems. Therefore, countries over the world aim to approach these problems by launching sustainable city programs. On April 22, 2016, China signed the Paris Agreement at the United...doctoral thesis 2018

Kuitert, L. (author), Volker, L. (author), Hermans, M.H. (author)In today’s construction industry we witness an increase in public private collaboration in the delivery of public goods. By transferring operational responsibility to private contractors, public construction clients have fewer possibilities to directly influence and steer the outcomes of these processes while remaining socio-political...conference paper 2018

Gbadegesin, J.T. (author)Recent critique against the past urban housing provision strategies in Nigeria was that the low-income groups are marginalised. It then led to the adoption of public private partnership (PPP) initiative with a view to pursuing the broad goal of housing-for-all in Nigeria. Most recent studies have however criticised the effectiveness of the...journal article 2017

Treffers, N. (author)Many different Global Navigation Satellite Systems (GNSS) are currently in orbit or are being deployed. Research on positioning techniques using these satellites is ongoing. The Curtin GNSS Research Centre has developed a software tool for further testing of these techniques. This thesis represents the testing done on the Curtin PPP-RTK User...master thesis 2016

De Bakker, P.F. (author)Precise Point Positioning (PPP) is a Global Navigation Satellite System (GNSS) processing method with the objective of providing high positioning accuracy without the need for a nearby base station or dense network of reference stations operated by the user. To reach this objective, PPP uses the very precise carrier phase measurements in...doctoral thesis 2016

Gbadegesin, J.T. (author), van der Heijden, H.M.H. (author), Boelhouwer, P.J. (author), Oladokun, S.O. (author)The argument in the recent time was that the past strategies of the government in housing provision were obviously in favour of high income groups as the low-medium groups are victims of housing inadequacy in cities. The corollary to the situation resulted to the call for the adoption of public private partnership (PPP) initiative in order to...conference paper 2016

Van den Assem, S.C.E. (author)Due to the difficulties around the F component, it recently appears that more attention has been paid to exploring the alternatives of bank financing. New forms of integrated contracts are gradually being developed that are funded by public resources, but are directed at producing comparable incentives as produced by the F component. In addition...master thesis 2014

Van der Post, F.H.L. (author)This thesis focuses on Public Private Partnerships (PPPs) for infrastructural projects, in which PPPs entail Design Build Finance Maintain (and Operate), or DBFM(O) contracts. The main differences of such contracts with more traditional contracts is the establishment of a project-specific Special Purpose Company (SPC), the need for external...master thesis 2011

Hansen, R. (author), Prins, M. (author), Straub, A. (author)In most literature integrated contracting and procurement is assumed to result in more innovative solutions as a result of the intended process integration. This paper explores Design Build Finance Maintain Operate (DBFMO) cases in the Netherlands on resulting innovations focusing on maintenance and energy-use. It is assumed that in DBFMO...conference paper 2011

Lannes, A. (author), Teunissen, P.J.G. (author)The first objective of this paper is to show that some basic concepts used in global navigation satellite systems (GNSS) are similar to those introduced in Fourier synthesis for handling some phase calibration problems. In experimental astronomy, the latter are at the heart of what is called ‘phase closure imaging.’ In both cases, the analysis...journal article 2010

Meulenbeld, T. (author)This research examines the efforts of the Public Private Comparator (PPC) at the decentralized level in the Netherlands. The PPC is a financial-economic assessment tool that can be used before a tender to determine whether there is a surplus value for a specific project (real estate or infrastructure) in the form of a Public Private Partnership...master thesis 2010
