Meulblok, Vera (author)The efficiency of a logistic service provider's network can be improved by implementing a receiver-led consolidation policy. This policy means that shipments destined to the same location are consolidated in one truck. The literature states that by doing this the costs, CO2 emissions and number of vehicle movements can be reduced. However,...master thesis 2020

Neto, A. (author), Fiorellini Bernardis, A. (author), Emer, Diego (author), Freni, Angelo (author), Llombart, Nuria (author)The observable field is defined as the portion of the incident field that can contribute to the power received by an antenna. Recently, the observable field was estimated for a plane wave incidence. Here, the procedure is extended to a general incident field expressed as a superposition of homogeneous plane waves. The observable field concept...journal article 2020

Beenen, Kathelijne (author)Accurate weather forecasting plays an important role in predicting precipitation events. With the warming climate the precipitable water vapour in the atmospheric is increasing. Since weather parameters as precipitable water vapor have a high spatial variability, interpolation of water vapor data over an area of hundreds of kilometer does not...student report 2020

Krietemeyer, A. (author), van der Marel, H. (author), van de Giesen, N.C. (author), ten Veldhuis, Marie-claire (author)The recent release of consumer-grade dual-frequency receivers sparked scientific interest into use of these cost-efficient devices for high precision positioning and tropospheric delay estimations. Previous analyses with low-cost single-frequency receivers showed promising results for the estimation of Zenith Tropospheric Delays (ZTDs)....journal article 2020

Wahlström, Johan (author), Kok, M. (author), Porto Buarque de Gusmão, Pedro (author), Abrudan, Traian E. (author), Trigoni, Niki (author), Markham, Andrew (author)Magneto-inductive navigation is an inexpensive and easily deployable solution to many of today’s navigation problems. By utilizing very low frequency magnetic fields, magneto-inductive technology circumvents the problems with attenuation and multipath that often plague competing modalities. Using triaxial transmitter and receiver coils, it is...journal article 2020

Odolinski, Robert (author), Teunissen, P.J.G. (author)The key to precise global navigation satellite system (GNSS) positioning is carrier phase integer ambiguity resolution with a high success rate. On the other hand when the success rate is too low, the user will normally prefer the float solution. The alternative can be to use the best integer equivariant (BIE) estimator, since it is optimal in...journal article 2020

van Dongen, Kirsten (author)Heavy rainfall, combined with expanding (unplanned) urban settlements in flood prone areas, expose Dar es Salaam (Tanzania) to the risks of flooding. The urbanisation is so rapid in many areas that it is not beneficial to carry out expensive surveys which are quickly out of date. The work carried out by community-mapping project Dar Ramani Huria...master thesis 2019
