System Performance Evaluation of Hybrid Beamforming with Shaped Beam Patterns for mm-Wave 5G Base Stations

Hybrid beamforming (HBF) architecture provides promising trade-offs between the system performance and computational/hardware complexity in practical implementations of millimeter wave (mm-Wave) massive multiple-input multiple-output (mMIMO) 5th generation (5G) mobile networks compared to its fully digital beamforming (DBF) counterpart. In this...

Smartphone-Based 3D Modelling of Mangroves Geometry: Parameter Measurement and Accuracy Research

The wave attenuation of vegetation plays an increasingly important role in flood control in coastal areas. Past studies have found that the interaction of waves with vegetation mainly depends on hydraulic conditions and vegetation characteristics. Therefore, it is necessary to build vegetation models and quantify vegetation characteristics...

Nonlinear Wave Loads on Offshore Wind Support Structure

Though booming, offshore wind development is constrained by its high cost. One potential way to meet this challenge is to reduce the uncertainty in wave modeling and hydrodynamic loads calculation model for offshore wind support structure design. The thesis covers two aspects for calculating loads acting on a offshore wind support structure: an...

Hydrodynamic loads on buildings caused by overtopping waves

There is a chance that storm surges occurring in coastal areas cause overtopping over wide crested dikes. The overtopping water results in a hydrodynamic load on the structures built on top of the crest. This is for example the case at the Belgian coast where houses and hotels are constructed on top of the dike crest. In this study, physical...
