Multilayer thin film thickness measurement method: to measure thickness of liquid thin film within a layer stack

The research objective of this research is to develop a measurement method that can measure thin film thicknesses through a multilayer that consists of both surrounding thick layers and in between thin films. An optical non-contact measurement method is researched and developed to non-destructively measure the thickness of a liquid thin film,...

Future Energy Carriers in Office Buildings: Techno-economic assessment of integrated energy and mobility systems

In the energy transition the expansion of the amount of renewable energy resources requires new methods for the design of energy systems. To deal with intermittent energy production, different energy technologies and solutions are in development. Hydrogen is a main candidate for this goal. Using Fuel Cell or Battery Electric Vehicles as flexible...

On the Influence of Fines on the Sedimentation Velocity in Hopper Dredgers

Clay particles, known for their adhesive properties, are commonly encountered in underwater soils. When producing large quantities of sand by means of dredging, fines are a byproduct and cause important viscosity changing effects altering the sand settling behavior. Much is already known in this field but knowledge lacks in the area where sand...

A Continuous Calibration Method For the Transfer Stabilization of Successive Detection Logarithmic Amplifiers

To ensure efficient and reliable operation of power amplifiers it is very important to precisely measure and control the power of the signal they transmit. A device most often used to do precise power measurements of RF systems is the so-called RF power detector. As this detector is used as measurement device the precise measurement ability of...
