Localization is a crucial skill in mobile robotics because the robot needs to make reasonable navigation decisions to complete its mission. Many approaches exist to implement localization, but artificial intelligence can be an interesting alternative to traditional localization techniques based on model …

An energy harvesting device for obtaining instantaneous energy from drops without needing of moving the drops along the device, in a reduced scale and combinable with other types of harvesting devices, the energy harvesting device comprising one or more triboelectric generators comprising a bottom electrode, …

The transmission of constant-envelope orthogonal frequency division multiplexing (CE-OFDM) signals, based on electrical phase modulation, was shown to improve the tolerance to noise and the nonlinearity introduced by light-emitting diodes (LEDs) in visible light communication (VLC) systems. This allows …

The performance of a visible light communication (VLC) system based on power domain non-orthogonal multiple access (PD-NOMA) is experimentally evaluated in this paper. The simplicity of the adopted non-orthogonal scheme is provided by the fixed power allocation method at the transmitter and the single …

Purpose The aim of this study is to provide insights into how the purchasing function can increase the maturity of smart maintenance management (SMM) in construction clients by (1) assessing current SMM maturity and (2) developing an adapted service triad for purchasing's meaningful involvement in SMM. …

A resource optimization methodology is proposed for application in long range wide area networks (LoRaWANs). Using variable neighborhood search (VNS) and a minimum-cost spanning tree algorithm, it reduces the implementation and the maintenance costs of such low power networks. Performance evaluations …

Research suggests that construction clients, as building owner-occupier, are struggling to implement smart maintenance. This thesis assumes that this is due to a failure to fully understand the institutional complexities of smart maintenance. Hence, the aim of this thesis was to improve our understanding …

Conflict lies at the core of urban sustainability transitions and the indispensable structural changes that accompany them. In this chapter we examine the RESILIO project, a multi-actor collaboration in Amsterdam aiming to transition towards a 'climate proof' city through smart water retention systems …
