Reputation-Based Data Carrying for Web3 Networks

Web3 networks are emerging to replace centrally-governed networking infrastructure. The integrity of the shared public infrastructure of Web3 networks is guaranteed through data sharing between nodes. However, due to the unstructured and highly partitioned nature of Web3 networks, data sharing between nodes in different partitions is a...

Developing water and sanitation services in refugee settings from emergency to sustainability - The case of Zaatari Camp in Jordan

Three years after Zaatari camp was established in the Hashemite Kingdom of Jordan, to host Syrian refugees, its population has grown to 82,000 persons. Zaatari is one of the largest refugee camps in the world, in one of the most water scarce areas on earth. Since its establishment, drinking water has been delivered by trucks to communal...

Participation and Data Quality in Open Data use: Open Data Infrastructures Evaluated

Infrastructures may improve the use of Open Government Data (OGD) by providing insight in how individuals can participate in data reuse and in the quality of open data. Yet, most OGD infrastructures do not support such activities. The objective of this paper is to evaluate the importance and usability of participation mechanisms and data quality...

European high speed railway, understanding design contradictions for long-term urban architecture strategy

Analysing outsourcing policies in an asset management context: A six-stage model

Asset managers of civil infrastructure are increasingly outsourcing their maintenance. Whereas maintenance is a cyclic process, decisions to outsource decisions are often project-based, and confusing the discussion on the degree of outsourcing. This paper presents a six-stage model that facilitates the top-down discussion for analysing the...

Infrastructure Management: Dynamic control of assets

The infrastructure in the Netherlands is crucial for economic development on a national scale. Dramatic increases of transport and mobility accelerate ageing of infrastructure. The GNP of the Netherlands is strongly related to transport and to the two main ports (Port of Rotterdam and Amsterdam Airport Schiphol). The Netherlands is used to a...

Benchmark analysis of railway networks and undertakings

Benchmark analysis of railway networks and companies has been stimulated by the European policy of deregulation of transport markets, the opening of national railway networks and markets to new entrants and separation of infrastructure and train operation. Recent international railway benchmarking studies which are mostly based on statistical...

3D Spatial Information Infrastructure for the Port of Rotterdam

The maintenance of the complex infrastructure and facilities of Port of Rotterdam is based on large amounts of heterogeneous information. Almost all activities of the Port require spatial information about features above- and under- ground. Current information systems are department and data oriented and cannot reflect the new process- & project...

Architectural contextualism and emerging hybrid morphologies

Infrastructure networks have always been the primary feature of urbanism. As any aspects of urban environments, the understanding of infrastructure networks and their practices have witnessed changes due to the shifts first to modernist ideal and then to the globalized world view. In oppose to the former fragmented nature of infrastructure...

Google maps for crowdsourced emergency routing

Gathering infrastructure data in emergency situations is challenging. The affected by a disaster areas are often large and the needed observations numerous. Spaceborne remote sensing techniques cover large areas but they are of limited use as their field of view may be blocked by clouds, smoke, buildings, highways, etc. Remote sensing products...

Simulation-based design for infrastructure system simulation

Simulation models are often used to analyze the behavior and performance of infrastructure systems. The use of simulation models in multi-actor design processes is restricted to the analysis phase after conceptual designs have been completed. To use simulation models throughout the design process, simulation environments need to be adapted to...

Modelling cooperative agents in infrastructure networks

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...

Infrastructure asset management: The valuation of complex objects

For two years now, Rijkswaterstaat, an agency of the Dutch Ministry of Transport, Public Works and Water Management, is required to have a financial administration, which is based on accrual accounting principles. This involves the use of a balance sheet and the equivalent of a profit and loss statement. These documents will the basis for...

Balancing Infrastructure and Innovation in Geoinformation-infrastructure projects

Spatial information is increasingly exchanged between organizations within a National Geo Information Infrastructure (NGII). While a lot has been written on implementation strategies, yet little is known what really goes on in concrete projects. In this paper an ethnography is presented based on a narrative approach of a Dutch project, in which...

Charging Stations for Urban Settings the design of a product platform for electric vehicle infrastructure in Dutch cities

This paper reflects the essential role of supportive infrastructure in the mass implementation of electric drive vehicle technology. A focus is placed on the development of comprehensive systems that provide efficient and diverse recharging solutions for vehicle drivers. Mass adoption of electric mobility will reflect advances in the vehicles...

Toposcopy: A modelling tool for CITYGML

The new 3D standard CityGML has been attracting a lot of attention in the last few years. Many characteristics of the XML-based format make it suitable for storage and exchange of virtual 3D city models. It provides possibilities to store semantic and geometric information and has the potential to incorporate topological models. A large number...

Building a NGII: Balancing between infrastructure and innovation

A multitude of studies has been published on how National Geo Information Infrastructures (NGII), also known as Spatial Data Infrastructures (SDI), should be designed, set up and monitored. Scientific research on day-to-day experiences, on what is really happening in NGIIprojects is hard to find. We propose a narrative approach to elicit...

Constructing metropolitan landscapes of actuality and potentiality

The Flat City space syntax model (Read, 2005), has been developed to extend the functionality of the space syntax method into the ‘periphery’ (the metropolitan) of the contemporary metropolitan city, and to provide a method for describing and evaluating the form of contemporary urban landscapes. The Flat City model proposes that the environment...
