Categorical based feature modeling on a zero inflated performance measure

ASML produces TwinScan NXT machines that are used for the production of microchips. The machines ensure that an accurate pattern of DUV-light passes a lens and that it is projected as accurate as possible on the wafer. To ensure that the focal point of the converged DUV-light falls exactly onto the wafer, the leveling functionality is of great...

Improving the sustainability approach of integrated infrastructural projects

Based on the research to the opportunities in the civil engineering sector, there can be concluded that the amount and the types of the opportunities differs per project category. The most striking aspect in the elaboration of the different opportunities is that the most influential opportunities are (partly) driven by impacts on external...

Simulation of a Detect and Sense System

Under current regulations, Unmanned Aerial Vehicles (UAVs) are prohibited from operating in non- segregated airspace. The absence of a pilot is considered to be a potential hazard because the pilot is responsible for the separation with other aircraft. In unmanned aviation the pilot, or operator, can never detect possible separation conflicts...

Salinity in Lake Maracaibo

Lake Maracaibo, Venezuela is an outstanding example of today's conflict of interests between protection of natural resources and economic development because of the extensive use of the area. The exchange and interaction between the fresh water of the Lake and the saline water from the Gulf of Venezuela is an important mechanism in the...
