Convex modeling of pumps in order to optimize their energy use

This study presents convex modeling of drainage pumps so that real-time control systems can be implemented to minimize their energy use. A convex model is built based on pump curves and then used in mixed-integer optimization to allow pumps to be turned on or off. It is implemented as an extension to the open source software package RTC-Tools...

Error Control Coding Schemes for Ultra-wideband Impulse Radio Systems

Ultra-wideband (UWB) is a promising technology that offers a potential solution for the data rate, cost, power consumption and physical size requirements of the next generation wireless devices. UWB may also play an important role in the realization of future heterogeneous networking. This technology has recently gained significant interest from...

Morphodynamic modelling of estuarine channel-shoal systems

In this research, the initial formation and long-term evolution of channel-shoal patterns in schematised basins is simulated using a model based on the software package Delft3D. The resulting channel-shoal patterns are validated with field observations, among which the Western Scheldt estuary. This has proven that a complex model is able to...

Sutrench model: Two-dimensional vertical mathematical model for sedimentation in dredged channels and trenches by currents and waves

The construction of a tunnel or a pipeline or a new harbour generally requires the dredging of a channel or trench in a river or estuary. Depending on the geometry of the channel, various morphological problems may arise such as sedimentation and erosion of the channel bed, local erosion near the head of the tunnel elements placed in the channel...
