Reproducing Sound Fields Using MIMO Acoustic Channel Inversion

Martin Vetterli, Mihailo Kolundzija, Christof Faller

Sound fields are essentially band-limited phenomena, both temporally and spatially. This implies that a spatially sampled sound field respecting the Nyquist criterion is effectively equivalent to its continuous original. We describe Sound Field Reconstruct ...

Cloud condensation nuclei activity of isoprene secondary organic aerosol

Athanasios Nenes, Spyros Pandis

This work explores the cloud condensation nuclei (CCN) activity of isoprene secondary organic aerosol (SOA), likely a significant source of global organic particulate matter and CCN, produced from the oxidation with OH from HONO/HOOH photolysis in a temper ...

Compressor Tree Synthesis on Commercial High-Performance FPGAs

Paolo Ienne, Philip Brisk, Hadi Parandeh Afshar

Compressor trees are a class of circuits that generalizes multioperand addition and the partial product reduction trees of parallel multipliers using carry-save arithmetic. Compressor trees naturally occur in many DSP applications, such as FIR filters, and ...

Optimal filtering of an incremental second-order MASH11 sigma-delta modulator

Maher Kayal, Sylvain Maréchal, François Krummenacher

This paper describes an optimal filter design procedure for a cascaded sigma-delta modulator, starting with a block schematic of a second-order topology and deriving step by step the optimal decoder. The presented filter enhances the resolution of the MASH ...

Direct-Ambient Decomposition and Upmix of Surround Signals

Christof Faller, Andreas Walther

Various direct-ambient signal decompositions, applicable to two-channel stereophonic signals, have been proposed previously. Strategies to enhance these decompositions for multi-channel surround audio signals are not obvious. A method is proposed, which es ...

Distributed processing of continuous sliding-window k-NN queries for data stream filtering

Karl Aberer, Ivana Podnar, Kresimir Pripuzic

A sliding-window k-NN query (k-NN/w query) continuously monitors incoming data stream objects within a sliding window to identify k closest objects to a query. It enables effective filtering of data objects streaming in at high rates from potentially distr ...

Video-rate fluorescence lifetime imaging camera with CMOS single-photon avalanche diode arrays and high-speed imaging algorithm

Edoardo Charbon, David Li

A high-speed and hardware-only algorithm using a center of mass method has been proposed for singledetector fluorescence lifetime sensing applications. This algorithm is now implemented on a field programmable gate array to provide fast lifetime estimates ...

Drop-coated metal-oxide gas sensor on polyimide foil with reduced power consumption for wireless applications

Nico de Rooij, Danick Briand, Jérôme Courbat

Highly miniaturized low-power drop-coated metal-oxide gas sensors on polyimide foil are presented. Drop-coating of SnO2-based material was successfully achieved on transducers as small as 15 μm on polyimide, a substrate compatible with the printed electron ...

An Energetic Based Method Leading to Merged Control Loops for the Stability of Input Filters

Philippe Barrade

In most of applications, power converters are controlled to allow their output current/voltage to follow the required reference values. For DC/DC and DC/AC converters, the control must take into account their input voltage, which must be rejected. In such ...

A low-voltage complementary metal-oxide semiconductor adapter circuit suitable for input rail-to-rail operation

Mirjana Banjevic

In this article, a low-voltage complementary metal-oxide semiconductor (CMOS) input signal adapter (ISA) suitable for input rail-to-rail operation of various types of analogue basic building blocks is presented. The adapter acts as a pre-stage with infinit ...
