Transmission Expansion Planning of Transnational Offshore Grids: A Techno-Economic and Legal Approach Case Study of the North Sea Offshore Grid

The new energy policy of the European Union (EU) with the core objectives of competitiveness, reliability and sustainability, has driven Europe into a transition towards a low carbon & sustainable electricity supply systems. Under the new policy, the European energy systems are pursing two major objectives. First is to shift the focus from...

Estimation of volcanic ash emissions using trajectory-based 4D-Var data assimilation

Volcanic ash forecasting is a crucial tool in hazard assessment and operational volcano monitoring. Emission parameters such as plume height, total emission mass, and vertical distribution of the emission plume rate are essential and important in the implementation of volcanic ash models. Therefore, estimation of emission parameters using...

A 24GHz Radar Receiver in CMOS

This thesis investigates the system design and circuit implementation of a 24GHz-band short-range radar receiver in CMOS technology. The propagation and penetration properties of EM wave offer the possibility of non-contact based remote sensing and through-the-wall imaging of distance stationary or moving objects. The feasibility of realizing...

High-Level Power Estimation and Optimization of DRAMs

Embedded systems have become an integral part of our life in the last few years in multifarious ways, be it in mobile phones, portable audio players, smart watches or even cars. Most embedded systems fall under the category of consumer electronics, such as televisions, mobile devices, and wearable electronics. With several players competing in...

Automatic Hardware Generation for Reconfigurable Architectures

Reconfigurable Architectures (RA) have been gaining popularity rapidly in the last decade for two reasons. First, processor clock frequencies reached threshold values past which power dissipation becomes a very difficult problem to solve. As a consequence, alternatives were sought to keep improving the system performance. Second, because Field...

Optimal Usage of Multiple Energy Carriers in Residential Systems: Unit Scheduling and Power Control

The world’s increasing energy demand and growing environmental concerns have motivated scientists to develop new technologies and methods to make better use of the remaining resources of our planet. The main objective of this dissertation is to develop a scheduling and control tool at the district level for small-scale systems with multiple...

Manifold mapping optimization with of without true gradients

This paper deals with the Space Mapping optimization algorithms in general and with the Manifold Mapping technique in particular. The idea of such algorithms is to optimize a model with a minimum number of each objective function evaluations using a less accurate but faster model. In this optimization procedure, fine and coarse models interact...

Robustness of networks

Our society depends more strongly than ever on large networks such as transportation networks, the Internet and power grids. Engineers are confronted with fundamental questions such as “how to evaluate the robustness of networks for a given service?”, “how to design a robust network?”, because networks always affect the functioning of a service....

Conception de réseau iBGP

BGP is used today by all Autonomous Systems (AS) in the Internet. Inside each AS, iBGP sessions distribute the external routes among the routers. In large ASs, relying on a fullmesh of iBGP sessions between routers is not scalable, so route-reflection is commonly used. The scalability of route-reflection compared to an iBGP full-mesh comes at...
