Syllabic Pitch Tuning for Neutral-to-Emotional Voice Conversion

Milos Cernak, Lakshmi Babu Saheer

Prosody plays an important role in both identification and synthesis of emotionalized speech. Prosodic features like pitch are usually estimated and altered at a segmental level based on short windows of speech (where the signal is expected to be quasi-sta ...

An optimally concentrated Gabor transform for localized time-frequency components

Benjamin Ricaud

Gabor analysis is one of the most common instances of time-frequency signal analysis. Choosing a suitable window for the Gabor transform of a signal is often a challenge for practical applications, in particular in audio signal processing. Many time-freque ...

Recursive Compressed Sensing

Martin Vetterli, Nikolaos Freris, Orhan Öçal

We introduce a recursive algorithm for performing compressed sensing on streaming data. The approach consists of a) recursive encoding, where we sample the input stream via overlapping windowing and make use of the previous measurement in obtaining the nex ...

Experimental demonstration of ray-optical refraction with confocal lenslet arrays

Toralf Scharf

We observe imaging through windows comprising pairs of confocal lenslet arrays that have different focal lengths but that are otherwise identical. Image space is stretched in the longitudinal direction only. Such windows are examples of METATOYs, optical c ...

Optoelectronically mismatched oligophenylethynyl-naphthalenediimide SHJ architectures

Natalie Renuka Banerji, Stefan Matile, Eric Vauthey

The objective of this study was to evaluate the possibility of photoinduced stack/rod electron transfer in surface “zipper” architectures composed of stacks of blue (B) naphthalenediimides (NDIs) along strings of oligophenylethynyl (OPE) rods. The synthesi ...

Performance of Anidolic Daylighting Systems in tropical climates – Parametric studies for identification of main influencing factors

Jean-Louis Scartezzini, Friedrich Linhart, Stephen Wittkopf

Making daylight more available in buildings is highly desirable, not only for reasons of energy-efficiency, but also for improvement of occupants’ health and well-being. Core-daylighting, that is daylight provision in areas situated at considerable distanc ...

Testing Closed-Source Binary Device Drivers with DDT

George Candea, Vitaly Chipounov, Volodymyr Kuznetsov

DDT is a system for testing closed-source binary device drivers against undesired behaviors, like race conditions, memory errors, resource leaks, etc. One can metaphorically think of it as a pesticide against device driver bugs. DDT combines virtualization ...
