Several leading lighting companies for example NXP and Philips work in a project to explore the next generation intelligent lighting system. One innovation of the project is using a distributed architecture to replace current centralized system to increase robustness and extensibility. As a core component of wireless lighting control system,...

Near-field source localization is an important aspect in many diverse areas such as acoustics, seismology, to list a few. The planar wave assumption frequently used in far-field source localization is no longer valid when the sources are in the near field. Near-field sources can be localized by solving a joint direction-of-arrival and range...

Energy-harvesting cognitive radio network has emerged as a solution to increase energy and spectrum efficiency. In this thesis, we propose short-term offline optimal power allocation algorithms for multi-user energy-harvesting cognitive radio networks considering interference between secondary users. Assuming finite and rechargeable batteries...

Multiple-input multiple-output (MIMO) radars achieve improved performance by the simultaneous transmission and reception of waveforms from different locations. Orthogonality of the transmitted waveforms is a requirement for allowing waveform separation at the receiver. In addition, signals with a large BT- product (e.g. coded signals) could be...

Gourov, V.N. (author)
Network monitoring is becoming more and more important as more Internet Service Providers and Enterprise networks deploy real-time services, like voice and video. Network operators need to have an up-to-date view of the network and to measure network performance with metrics like link usage, packet loss and delay, in order to assure the quality...

Kastelein, M.R. (author)
In earlier research projects, the depiction of airspace in which a loss of separation is predicted to occur has been explored as a means to increase conflict awareness. The computation of the conflict space is based on the current state of traffic and ownship. If the traffic maneuvers, the location and extent of the conflict space will change...

In the present ATC system conflicts between aircraft are detected and resolved in a stated-based approach. To meet traffic demand predictions, the global air traffic management (ATM) system needs revolutionary changes. Several visions on future ATM operations exist (e.g. NextGen, SESAR). A common function between the different visions is 4D...

Because of several - sometimes extreme - complications caused by cracks and weak spots in a metal industry roll, it is of great importance to detect these defects in time. Measurements on rolls with artificial- and natural defects have been performed. An imaging operator is introduced, which uses the measurement data to depict the correct...

Stoev, V.V. (author)
The intertwine of the optical and acoustic domains by the photoacoustic effect has given rise to the novel technique of photoacoustic imaging. As a relatively new field it faces many challenges from different character on the way to clinical applications. One of these challenges, which deteriorates image quality and sharpness, is noise. The...

Agbana, T.E. (author)
Wavelength measurement and control of lasers is of paramount importance and has found vast application in areas such as linear and nonlinear spectroscopy, multichannel wavelength division multiplexing, laser meteorology and applications which involve testing of laser and LED light sources to ensure spectral purity and power distribution. While...

Broadcasting by flooding is one of the most fundamental services for both wired and wireless networks. This also includes several sensor network applications that use broadcasting to spread information from one sensor node to the other sensor nodes in the entire sensor network. These wireless sensor networks have certain characteristics such as...

This work has been performed as a MSc. graduation project at Delft University of Technology on the topic `Loop-to-loop pulsed electromagnetic field signal transfer in layered configurations - application to inter-chip wireless communication'. The goal of this project was the derivation of an analytic expression for the space-time Green's...

Intelligent Transportation Systems (ITS) is becoming an important paradigm, because of its ability to enhance safety and to mitigate congestion on road traffic scenarios. Realizing the fact that data collection scheme from in-situ test beds for large number of vehicles is always expensive and time consuming, before being employed in large scale,...

Lu, H. (author)
In this thesis, major attention is paid to cooperative diversity as an alternative way to achieve spatial diversity when the multiple antenna structure is not an option. By adopting the cooperative relay nodes to forward information, we can mitigate the fading effects, increase the capacity, lower the bit-error rate, increase the achievable...

Information and Communication Technology (ICT) is changing the way we live and has become an essential part of our life. With the advent of Internet of Things (IoT), and Wireless Sensor Networks (WSN) in particular, the number of devices that are networked is increasing exponentially over the years. With the increase in number of ICT devices...

Wireless Body Area Network (WBAN) is used for communication among sensor nodes operating on, in or around the human body in order to monitor vital body parameters and movements. A typical sensor node in WBAN should ensure accurate sensing of the signal from the body, carry out low-level processing of the sensor signal, and wirelessly transmit...

We demonstrate that coherence vortices, singularities of the correlation function, generally occur in partially coherent electromagnetic beams. In successive cross sections of Gaussian Schell-model beams, their locus is found to be a closed string. These coherence singularities have implications for both interference experiments and correlation...
