Automation of Repetative Tasks in the Agricultural Sector

Labour in the agricultural sector is in short supply, while a large portion of the work is still being done manually. To speed up the work and guarantee the food supply of the future, Lely has started a project on agricultural automation. The aim of the project is to create a robot that can perform multiple repetitive tasks simultaneously, to...

Geological Research using Electronic Markers: Design of a signal processing system for chipless RFID

In this thesis, the implementation of a passive, chipless, frequency coded RFID detection system for bedload transport studies is proposed. The proposed tag will be deployed in the semi-arid Río Colorado, Bolivia with the aim to develop quantitative sediment transport models that relate transport to grain size. Different algorithms are explored...

Electronic markers for geological research: Tag Design

In this thesis, the implementation of a passive, chipless, frequency coded Radio-Frequency Identification (RFID) tag for bedload transport studies is proposed. The proposed tag will be deployed in the semi-arid Río Colorado river, Bolivia with the aim to develop quantitative sediment transport models that relate transport to grain size. The...

Radius Bending: User Element Testing and Investigation on Effect of Stacking Sequence on Out-of-plane Failure

A new doubly-curved shell element (ThickS4 element) is presented and tested for flat and singly curved configurations. The benchmark tests show good correlation for the ThickS4 element with the Abaqus S4 shell element and with 3D FEM for flat and highly curved configurations (R/t ≥ 4). For radius over thickness ratios smaller than 4 the element...

Automated launch, landing and storage of a kite power system

The Kite Power Group of the Wind Energy Department of Delft University of Technology has developed a pumping kite system to harvest high altitude wind energy (HAWP). HAWP technology is one of many renewable energy solutions that are emerging in a time at which Earth’s non-renewable energy resources are becoming scarce. The kite power system...
