Understanding Risk Extrapolation (REx) and when it finds Invariant Relationships

Generalizing models for new unknown datasets is a common problem in machine learning. Algorithms that perform well for test instances with the same distribution as their training dataset often perform severely on new datasets with a different distribution. This problem is caused by distributional shifts between the training of the model and...

Evaluating trading and sharing control for constraint motion tasks in a domestic environment using a remote controlled semi-autonomous robot

Automation in a domestic environment is not flawless and human interference will be necessary, for implementing robots in this environment. <br/>When remotely controlling semi-autonomous robots, proposed concepts can be divided into two main concepts: To trade control back and forth between the human and the operator and to share control...

Anticipating scope creep in the design phase of infrastructure projects: A case study on scope creep and its effects

Infrastructure projects in the construction industry are complex. This complexity leads to unavoidable changes in scope. When scope changes are not formalized and managed correctly, it is a risk contributing to project failure. A scope change that is not formalized is scope creep. This research looks at the causes and effects of scope creep in...

Optimal traffic flow at the IJ, Amsterdam: Investigation of the influence of the Java bridge and the Stenen Hoofd bridge on the traffic flow at the IJ in 2025 from the perspective of the recreational fleet

The city of Amsterdam increases with approximately 10,000 inhabitants per year and Amsterdam-North is strongly under development attracting housing, employment and (re)creational activities. This is expected to induce a growth of 65% in pedestrians and cyclists, referred to as slow traffic. crossing the river IJ in 2025. The city ferry system,...

DWIP - Durban Water Improvement Project

The water quality at the beachfront of Durban, KwaZulu-Natal, is currently insufficient to meet the Blue Flag standard, leading to health issues for the beach users. Since Durban can be recognised by its busy port and attractive beachfront, it is a major centre for tourism. This means that research on the source of this poor water quality and...

The current deflecting wall in a tidal harbour with density influences

Siltation is a serious problem for harbours situated on tidal rivers and estuaries. Maintenance dredging is necessary on a regular basis to guarantee safe navigation and is often a large cost factor. A means to prevent sediment from entering a harbour is the Current Deflecting Wall (CDW), which passively alters the water exchange at the harbour...
