Physical controls and a priori estimation of raising land surface elevation across the southwestern Bangladesh delta using tidal river management

The Ganges–Brahmaputra–Meghna delta in Bangladesh is one of the largest and most densely popu lated deltas in the world and is threatened by relative sea level rise (RSLR). Renewed sediment deposition through tidal river management (TRM), a controlled flooding with dike breach, inside the lowest parts of the delta polders (so called beels) can...

Core Temperature Estimation for a Cylindrical Cell Battery Module

Lithium ion (Li-ion) batteries in electric vehicle (EV) applications must operate within a narrow temperature range to ensure safety, performance and longevity. Hence, advanced thermal management strategies should have access to internal cell temperatures in a battery pack. In real world application, surface temperatures can be measured, but it...

Nanometer level freeform surface measurements with the NANOMEFOS non-contact measurement machine

Applying aspherical and freeform optics in high-end optical systems can improve system performance while decreasing the system mass, size and number of required components. The NANOMEFOS measurement machine is capable of universal non-contact and fast measurement of aspherical and freeform optics up to Ø500 mm, with an uncertainty of 30 nm (2σ)....

Soft-sensing for multilateral wells with downhole pressure and temperature measurements

Real-time monitoring of downhole oil, gas and water flows in wells can significantly improve the production performance of these wells when this flow rate information is used to manipulate inflow control valves. An example of this is the allocation of a gas or water cone to its entrance point in a multilateral well, allowing to close down the...

Quantitative roughness measurements with iTIRM

A new method, iTIRM, is used for quantitative surface roughness measurements of ground and polished surfaces and it is shown to be a useful tool for measuring total surface quality instead of individual roughness parameters.

Quantitative surface characterization using a Nomarski microscope

The use of a Nomarski microscope for the characterization of surface features will be presented. Since a Nomarski microscope measures slope values, the shape of a surface can be followed quantitatively. Besides, a Nomarski microscope can be used to analyze surface roughness in terms of rms value and a distinction between different types of...
