We formulated and implemented a procedure to generate aliasing-free excitation source signals. It uses a new antialiasing filter in the continuous time domain followed by an IIR digital filter for response equalization. We introduced a cosineseries-based general design procedure for the new antialiasing function. We applied this new procedure to implement the antialiased Fujisaki–Ljungqvist mod...

Layered manufacturing inherently suffers from staircase defects along surfaces that are gently slopped with respect to the build direction. Reducing the slice thickness improves the situation but never resolves it completely as flat layers remain a poor approximation of the true surface in these regions. In addition, reducing the slice thickness largely increases the print time. In this work we...

High-quality motion blur is an increasingly important and pervasive effect in interactive graphics that, even in the context of offline rendering, is often approximated using a post process. Recent motion blur post-process filters (e.g., [MHBO12,Sou13]) efficiently generate plausible results suitable for modern interactive rendering pipelines. However, these approaches may produce distracting a...

this thesis aims at putting together two of the vestest areas of study there is in humanities: bioethics and literature. the two novels in question, oryx and crake and the year of the flood, are considered as some of the most succssful examples of spculative fiction. in these novels the biological and environmental issues raised as looked at from a bioethics point of view.

We propose the use of high-degree resampling filters for improved temporal antialiasing, or as the result is often called, motion blur. Without temporal antialiasing, strange effects can occur within an animation, for example, wheels can appear to spin backwards at a certain speed. In a typical effort to overcome this, the camera shutter is left open over some period of time during the frame, l...

In narrowband active noise control systems, the dimension of the quiet zone around each error sensor is proportional to the wavelength of the noise being cancelled. In broadband active noise control systems, several error sensors per anti-noise source are used (two as a rule of thumb) in order to achieve larger cancellation regions, but the fact still remains that the size of the quiet zone wil...

Selecting rank-1 lattices with respect to maximized mutual minimum distance has been shown to be very useful for image representation and synthesis in computer graphics. While algorithms using rank-1 lattices are very simple and e cient, the selection of their generator vectors often has to resort to exhaustive computer searches, which is prohibitively slow. For the two-dimensional setting, we ...
