Improvements to the design process of the energy distribution system: A comparison between operational use of the energy distribution system of a naval ship and its expected use during the design phase

Smith, M.G. (author)

After a ship is delivered from a shipyard to a customer, its operational use is not yet structurally compared to its expected use. This lack of structural comparison results in limited verification and self-evaluation of the design process. The objective of this research is therefore to develop a method to analyze operational data and apply this...

Iterative linear focal-plane wavefront correction

Smith, C.S. (author), Marinica, R.M. (author), Den Dekker, A.J. (author), Verhaegen, M.H.G. (author), Korkiakoski, V. (author), Keller, C.U. (author), Doelman, N. (author)

We propose an efficient approximation to the nonlinear phase diversity (PD) method for wavefront reconstruction and correction from intensity measurements with potential of being used in real-time applications. The new iterative linear phase diversity (ILPD) method assumes that the residual phase aberration is small and makes use of a first...

Real-time wavefront reconstruction from intensity measurements

Smith, C. (author), Marinica, R. (author), Verhaegen, M. (author)

We propose an efficient approximation to the nonlinear phase diversity method for wavefront reconstruction from intensity measurements. The new method, iterative linear phase diversity (ILPD), assumes that the residual phase aberration is small and makes use of a first order Taylor expansion of the point spread function (PSF) performed for an...

Iterative learning control of a membrane deformable mirror for optimal wavefront correction

Haber, A. (author), Polo, A. (author), Smith, C.S. (author), Pereira, S.F. (author), Ubach, P. (author), Verhaegen, M. (author)

We present an iterative learning control (ILC) algorithm for controlling the shape of a membrane deformable mirror (DM). We furthermore give a physical interpretation of the design parameters of the ILC algorithm. On the basis of this insight, we derive a simple tuning procedure for the ILC algorithm that, in practice, guarantees stable and fast...

Online swing leg trajectory optimization for a force controllable humanoid robot

Smith, J.P. (author)

Humanoid robots are well suited to function in a world designed for humans. To function autonomously, it is important that the robot be robust against disturbances. Quick and accurate positioning of the swing foot allows the robot to recover from large disturbances. This thesis presents a novel controller that provides accurate foot positioning...

(author), Woida, R. (author), Tanner, R. (author)

The optical microscope onboard the Phoenix spacecraft has returned color images (4 ?m pixel?1) of soils that were delivered to and held on various substrates. A preliminary taxonomy of Phoenix soil particles, based on color, size, and shape, identifies the following particle types [generic names in brackets]: (1) reddish fines, mostly unresolved...
