For over a decade Darknet has been gaining tremendous popularity proportional to the growing concerns fostered by lack of anonymity and privacy on the World Wide Web. In the recent years, illegitimate use of the Darknet has resulted into investigation in the research community that is analogous to a domino effect further adding to popularity of...

A Chinese Digital Radio (CDR), labelled as GY/T 268-2013 [1], has been made and become effective in 2013 by SGAPPRFT (State General Administration of Press, Publication, Radio, Film and Television), which is an In-Band On-Channel (IBOC) digital audio broadcasting hybrided with analog FM signal in one FM channel. This report investigates the...

With the increase in data-intensive research in recent years, the Ethernet circuit, which is a high speed point-to-point connection, can be used for transmitting large amounts of data between sites. Customers use the trunk port to connect to the operator network. It allows multiple Ethernet circuits to share the same trunk port by using the...

Virtual Sectorization (ViS) is proposed as a solution to cope with the exponential growth of data traffic in mobile networks. Through the use of an Active Antenna System (AAS), two vertically separated beams (serving two distinct cells) are created within the original coverage area of a macro-cell. One of these cells, referred to as virtual cell...

With its three beams in different directions, the Transportable Atmospheric RAdar system (TARA) can provide a wind field estimation. These estimations are inaccurate when the Doppler velocities in one or more of the three beams are aliased. Amongst different approaches to solve aliasing are a continuity check up to four dimensions, staggering...

In the recent development of wireless communication several applications, such as spectrum sensing for cognitive radio are only interested in the power spectrum. These applications do not require the reconstruction of the original analog signal. According to the Whittaker-Kotelnikov-Shannon-Nyquist theorem, the sampling rate must be at least...

The goal of this project is to use a hybrid genetic algorithm to restore power to a power grid after a blackout by minimising the lost load and number of switches within a reasonable amount of time for power operators. The algorithm was tested on single-fault and multi-fault blackout systems. Based on the simulation results, the performance of...

Chinese digital audio broadcasting in FM band (commonly referred to as CDR) is a newly released digital audio broadcasting standard (GY/T 268-2013) which operates in the FM-band (87MHz to 108MHz) in China. This report introduces for the first time in English of this standard based on an official version written in Chinese, including multiplexing...

An equiangular sampling scheme and accessory measurement set-up for determining the directivity gain pattern of a commercially available smartphone is presented. Determining this directivity gain pattern based on these measuremenents was not possible, because next to the impulse response of the microphone also the impulse response of the...

Deze thesis gaat over het ontwerpen van antennes voor een draadloos audiosysteem. De zender van het audiosysteem beschikt over een IFA (inverted-F antenne) en de ontvanger over twee MIFA’s (meandered inverted-F antenne). Door de antennes te meten zijn waarden voor het compensatienetwerk ontworpen die het bereik van het audiosysteem moeten...

The goal of Non-Intrusive Appliance Load Monitoring (NIALM), or energy disaggregation, is to deduce which devices are active and how much energy they consume from observation of the time evolution of the total voltage or current in the electrical network. In this thesis, energy disaggregation is performed from the time series of power meter...

With rapid development of digital devices with wireless services, communication networks play a significant role in our daily lives. The explosive data demand makes it urgent to extend the capacity of the existing networks. Cognitive Radio (CR), which can sense and use the frequency band dynamically, can provide an efficient radio frequency...

In this thesis, the design of planar connected array of slots loaded with artificial dielectric layers (ADLs) is proposed to achieve wideband and wide-scan capabilities. ADLs are used due to the potential advantage of low surface-wave loss and high radiation efficiency. Whereas, the connected array of slots avoid the implementation of baluns...

During the period 2007-2011, the Microwave Sensing, Signals and Systems (MS3) division of TU Delft developed PARSAX, a high resolution FMCW research radar. Since it moves relatively slow, and it cannot utilize techniques such as monopulse or conical scanning, it is unable to track aircraft by itself. An external source of information is needed,...

Spoorwandelaars zijn een groot maatschappelijk probleem, zo zijn er elk jaar 200 zelfdodingen [1]. Door spoorwandelaars lopen treinreizigers elke dag veel vertraging op en daarnaast zorgen spoorwandelaars voor veel directe en indirecte kostenposten. Een goede oplossing is er op dit moment niet. Een radar-systeem lijkt een mogelijke oplossing....
