Duty ratio calculation for digitally feed forward controlled parallel connected buck-boost PFC Universiteit Gent
Power supply modules can be connected in parallel to build up a complex power system. Connecting many converters is more beneficial as compared to a single larger power unit because of components stress, modular implementation, flexible power requirements, and design variations. All of the above benefits can be achieved as long as the load current is distributed between the converters in a controllable manner. Digital feedforward control method ...
An identification algorithm for parallel Wiener-Hammerstein systems Vrije Universiteit Brussel
Block-oriented nonlinear models such as Wiener and Hammerstein models have the advantage that they are quite simple to understand and easy to use. Hammerstein and Wiener models can be extended to models containing extra blocks in a series connection such as Wiener-Hammerstein models. To further increase the modeling power of block-oriented models a parallel connection of Wiener-Hammerstein branches is considered. This paper presents a ...
Lagrangian submanifolds in complex projective space with parallel second fundamental form KU Leuven
From the Riemannian geometric point of view, one of the most fundamental problems in the study of Lagrangian submanifolds is the classification of Lagrangian submanifolds with parallel second fundamental form. In 1980's, H. Naitoh completely classified the Lagrangian submanifolds with parallel second fundamental form and without Euclidean factor in complex projective space, by using the theory of Lie groups and symmetric spaces. He showed that ...
Higher order parallel surfaces in the Heisenberg group KU Leuven
We give a classification of k-parallel surfaces in the three-dimensional Heisenberg group. In particular, we prove that every k-parallel surface in the Heisenberg group is a vertical cylinder over a polynomial spiral of degree at most k−1.

Parallel Assembly of Carbon Nanotubes for NEMS Applications (Parallelle assemblage van koolstof nanobuizen voor NEMS applicaties) KU Leuven
The main theme of this Ph.D. thesis is about the use of single-walled carbonnanotubes (SWCNTs) as mechanical components for (nano) -electromechanical system(NEMS) applications. The objective of this work is to develop an industry-relevanttechnique to fabricate devices comprising of horizontally aligned individual SWCNTssuspended over the substrate (to ensure their mechanical functionality) at multiple andspecific on-chip sites in parallel, ...
Data-parallel intra decoding for block-based image and video coding on massively parallel architectures Universiteit Gent
Scalability of the parallel MLFMA Universiteit Gent
This paper investigates the scalability of the parallel multilevel fast multipole algorithm (MLFMA). The scalability of a parallel algorithm is its ability to handle a larger problem on a proportionally larger parallel environment without loss of efficiency. It is demonstrated that this is closely related to the distribution of the workload among the different nodes: conventional spatial and hybrid partitioning techniques do not lead to a ...
