Ligtvoet, B.R. (author), Verbree, E. (author), Gorte, B.G.H. (author)There has been a steady increase in applications that rely on crowdsensing to gather data for analysis purposes. Crowdsensing enables the use of dynamic sensors to collect data on static objects of interest. However, using dynamic sensors in this way causes a problem. The focus of the collected data is on the position of the sensor, not on the...conference paper 2018

Werker, C. (author), Ubacht, J. (author), Ligtvoet, A. (author)Entrepreneurs are often envisioned as small private start-up firms operating against all odds. Here, we investigate how in the context of the Triple Helix various entrepreneurs form communities and drive institutional and technological change. To theoretically shape a socialized view of entrepreneurship, we use the Triple Helix approach. Our...journal article 2017

(author)The distribution of people in buildings, the occupancy of lecture-, work- and study places and the accessibility of facilities are essential information at university campuses who have to cope with limited and even shrinking budgets and huge, rising real estate costs. Only little insight is gained in both occupancy and movement patterns with...conference paper 2016

(author), Slager, K. (author), Vermoolen, M.S. (author), Hasan, S. (author), Hoang, V. T M (author), van Halsema, G (author)Sectoral planning on water, agriculture and urban development has not been able to prevent increased flood risks and environmental degradation in many deltas. Governments conceive strategic delta planning as a promising planning approach and develop strategic delta plans. Such plans are linked to actions and means for implementation in the...journal article 2016

Ligtvoet, A. (author), Cuppen, E.H.W.J. (author), Di Ruggero, O. (author), Hemmes, Kas (author), Pesch, U. (author), Quist, J.N. (author), Mehos, D.C. (author)This paper reports on the refinement of constructive conflict methodology (CCM) combining Q methodology and stakeholder dialogue workshops for gas futures for the Netherlands. Since the end of the 1950s, natural gas exploration and exploitation has been a major focus of the Dutch energy policy. Discussions about the future of energy in the...journal article 2016

Ligtvoet, A. (author), van de Kaa, G. (author), Fens, T.W. (author), van den Hoven, M.J. (author), van Beers, Cees (author), Herder, P.M. (author)The interconnected nature of the different components of smart grids is a prime example of complexity in technological systems. Developing such systems is highly dependent on the wishes and needs of end-users and other stakeholders. We argue that stakeholder values should be taken into consideration during the design and standardisation of...conference paper 2014

van de Kaa, G. (author), Ligtvoet, A. (author), Fens, T.W. (author), Herder, P.M. (author)Smart home energy systems are technically possible to realize but are not yet applied on a large scale partly due to the fact that no common standards exist that enable interconnection of components that make up these smart energy systems. Multiple standards have been developed which are competing in standards battles. In this paper we conduct a...conference paper 2014

Chappin, E.J.L. (author), Ligtvoet, A. (author)Sustainability policy in the early 2000s is based on and therefore influenced by scientific literature on ‘transition’. The importance of this link has inspired the authors to explore the structure of cooperating authors and citation networks in the field. In order to understand ‘transition’ literature, we compare it with an alternative term for...journal article 2013

Ligtvoet, A. (author)To ensure dependable, affordable, and sustainable use of energy, stakeholders in energy production, distribution, and consumption are increasingly seeking for cooperation. They aim to jointly tackle large energy projects in an environmental context that is changing at an increasing rate, towards increasing complexity. Cooperation is seen as a...doctoral thesis 2013

Volker, L. (author), Ligtvoet, A. (author), van den Boomen, M. (author), Wessels, Peter (author), van der Lei, T.E. (author), Herder, P.M. (author)In times of restructuring governmental policies and resources, the<br/>need for strategic asset management is growing. Maturity models offer<br/>organisations a structure to assist them in improving their asset management<br/>performance. We present the results of a repeated maturity measurement based<br/>on the infrastructure management...journal article 2013

Chappin, E.J.L. (author), Ligtvoet, A. (author)The terms ‘transition’ and ‘transition management’ encompass the change towards a more sustainable society and embody questions of how this goal should be achieved. Researchers under the banner of ‘transition’ are concentrated in the Netherlands. To find out to what extent ‘transition’ is a Dutch preoccupation, we perform a literature search to...conference paper 2012

Van der Lei, T.E. (author), Ligtvoet, A. (author)For public and semi public organizations the use of risk assessment matrices is becoming a standard approach for asset management decisions. The risk matrix allows companies to assess the chance and effects of different risks with respect to proposed investment decisions. When the values in the risk matrix reflect the company values, the risk...conference paper 2012

Ligtvoet, A. (author), Chappin, E.J.L. (author)In our energy-restricted world, planners and engineers have to cope with problems of CO2 emissions and oil- and gas-shortages. Many planning activities not captured under the heading of “futures studies” share common goals like dealing with an uncertain, complex future. We focus on two novel approaches: agent-based modelling and serious games....journal article 2012

Ligtvoet, A. (author)Although constructing a district heating network could be portrayed as a simple cost/benefit calculation, we suggest that other factors play an important role that cannot be ignored. In this contribution, we suggest that theories concerning cooperation (in industrial networks) roughly apply to micro (e.g. attitudes toward risk and trust), meso ...conference paper 2012

(author)Asset management aims at improving the overall performance of assetintensive industries by making and executing systematic and highest value decisions about the use and care of assets. To assist organizations to improve their asset management performance, maturity models can be used. In this paper we describe two applications of the...conference paper 2012

Ligtvoet, A. (author), Chappin, E.J.L. (author), Stikkelman, R.M. (author)This paper describes the translation of concepts of cooperation into an agent-based model of an industrial network. It first addresses the concept of cooperation and how this could be captured as heuristical rules within agents. Then it describes tests using these heuristics in an abstract model of an industrial network. The discussion addresses...conference paper 2010

Ligtvoet, A. (author)Future price developments and availability of energy resources are uncertain. Therefore, developers of energy infrastructures will have to consider different scenarios in their planning. Moreover, the implementation of large infrastructures requires the cooperation of several actors, which adds to the uncertainty. In this paper we describe the...conference paper 2010

(author)Charge Coupled Devices (CCDs) optically coupled to scintillation crystals can be used to construct high resolution gamma cameras. Previously, several groups have reported intrinsic detector spatial resolutions below 100 microns. When the CCD images can be read out fast enough, the energy and interaction position of individual gamma quanta can be...journal article 2009
