Distinguishing analyte from noise components in mass spectra of complex samples: where to cut the noise?
Yury Tsybin, Anton Kozhinov, Luca Fornelli, Konstantin Zhurov
Fourier transform mass spectrometry (FTMS) enables comprehensive analysis of complex molecular mixtures. Given the broad intensity ranges of components in the mass spectra, it is imperative to accurately determine a noise threshold level above which peak a ...
Amer Chemical Soc2014Beyond KernelBoost
Pascal Fua, Vincent Lepetit, Roberto Rigamonti
In this Technical Report we propose a set of improvements with respect to the KernelBoost classifier presented in [Becker et al., MICCAI 2013]. We start with a scheme inspired by Auto-Context, but that is suitable in situations where the lack of large trai ...
2014Passive phase noise cancellation element
Luis Guillermo Villanueva Torrijo
A passive electro-mechanical device that reduces phase noise in oscillators, thereby improving their frequency precision. The noise reduction device can consist of a pair of coupled nonlinear resonators that are driven parametrically-by modulating their na ...
2014Hybrid MOS-PN photodiode with positive feedback for pulse-modulation imaging
Maher Kayal, Adil Koukab, Denis Sallin
A new type of CMOS compatible photodetector, exhibiting intrinsic light-to-time conversion, is proposed. Its main objective is to start the time-to-digital conversion directly at its output, thereby avoiding the cumbersome analog processing. The operation ...
Optical Society of America2014Noise facilitation in associative memories of exponential capacity
Mohammad Amin Shokrollahi, Amin Karbasi, Amir Hesam Salavati
Recent advances in associative memory design through structured pattern sets and graph-based inference al- gorithms have allowed reliable learning and recall of an exponential number of patterns. Although these designs correct external errors in recall, th ...
Mit Press2014Active vibration control using self-sensing actuators: an experimental comparison of piezoelectric and electromagnetic technologies
The paper addresses the practical implementation of active vibration control using self-sensing actuators, intending to equip smart structures. The control objective is to reduce the structural vibration of a simply-supported plate subject to time-harmonic ...
ASME2014Backpropagation Imaging in Nonlinear Harmonic Holography in the Presence of Measurement and Medium Noises
In this paper, the detection of a small reflector in a randomly heterogeneous medium using secondharmonic generation is investigated. The medium is illuminated by a time-harmonic plane wave at frequency ω. It is assumed that the reflector has a nonzero sec ...
2014Driver electronics for efficient low noise stepper motor operation
Stepper motors are a very convenient and economical solution for accurate positioning applications where long lifetime and low wear are required. Their particularly simple open-loop operation reduces the number of control components to a minimum. However, ...
2014A Novel Technique for Online Partial Discharge Pattern Recognition in Large Electrical Motors
In this paper, a fully automated system for source detection of the partial discharges (PD) as an online diagnosis test in rotating machineries is proposed. This technique uses a modified version of the Expectation Maximization-based (EM) clustering techni ...
Ieee2014RELICA: A method for estimating the reliability of independent components
Silvestro Micera, Fiorenzo Artoni
Independent Component Analysis (ICA) is a widely applied data-driven method for parsing brain and non-brain EEG source signals, mixed by volume conduction to the scalp electrodes, into a set of maximally temporally and often functionally independent compon ...
