Characterization of a 9-Decade Femtoampere ASIC Front-End for Radiation Monitoring
Maher Kayal, Evgenia Voulgari, François Krummenacher, Daniel Perrin
An ultra-low current sensing digitizer circuit was designed for radiation monitoring for personnel and environmental safety at CERN. The Ultralow Picoammeter 2 (Utopia 2) ASIC includes some key functionalities like on-chip active leakage current compensati ...
2018Peptide Bond Ultraviolet Absorption Enables Vibrational Cold-Ion Spectroscopy of Nonaromatic Peptides
Vladimir Kopysov, Aleksandr Pereverzev
Peptide-bond VUV absorption is inherent to all proteins and peptides. Although widely exploited in top-down proteomics for photodissociation, this absorption has never been spectroscopically characterized in the gas phase. We have measured VUV/UV photofrag ...
2018Experimental and theoretical investigation of the operating principles of the Figure-9 laser, Advanced Photonics 2018 (BGPP, IPR, NP, NOMA, Sensors, Networks, SPPCom, SOF)
Camille Sophie Brès, Ivan Cardea, Svyatoslav Kharitonov
We present a theoretical vectorial model, validated by experimental measurements, describing the dependence of the Figure-9 laser output power, operating in continuous wave, on the coupling ratio of the directional coupler. ...
Optical Society of America2018Closed-loop Controlled Brillouin Optical Time-Domain Analysis
Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Zhisheng Yang
A closed-loop controlled BOTDA distributed optical fibre sensor is proposed for tracking fast temperature-strain evolution. The measurement time is reduced by two orders of magnitude with respect to classical BOTDA sensing, while keeping the same accuracy ...
IEEE2017Amplified Optomechanical Transduction of Virtual Radiation Pressure
Here we describe how, utilizing a time-dependent optomechanical interaction, a mechanical probe can provide an amplified measurement of the virtual photons dressing the quantum ground state of an ultrastrongly coupled light-matter system. We calculate the ...
Amer Physical Soc2017Data-Interpretation methodologies for Non-Linear Earthquake Response Predictions of Damaged Structures
Ian Smith, Pierino Lestuzzi, Yves Sylvain Gilles Reuland
Seismic exposure of buildings presents difficult engineering challenges. The principles of seismic design involve structures that sustain damage and still protect inhabitants. Precise and accurate knowledge of the residual capacity of damaged structures is ...
2017A Practical Engineering Approach to Interpreting Measurement Data in Uncertain Contexts
Ian Smith, Sai Ganesh Sarvotham Pai
Measurement data interpretation has the potential to improve asset management through quantification of reserve capacity and execution of well-engineered interventions. Many recent proposals for data interpretation that include uncertainty are not appropri ...
ASCE2017Data Reconciliation for Reaction Systems Using Extents and Shape Constraints
Dominique Bonvin, Julien Léo Billeter, Sriniketh Srinivasan
Concentrations measured during the course of reactions are typically corrupted by random noise. Data reconciliation techniques improve the accuracy of measurements by using redundancies in the material and energy balances expressed as relationships between ...
Elsevier2017A Versatile Noise Performance Metric for Electrical Impedance Tomography Algorithms
Jean-Philippe Thiran, Fabian Braun, Martin Proença
Electrical impedance tomography (EIT) is an emerging technology for real-time monitoring of patients under mechanical ventilation. EIT has the potential to offer continuous medical monitoring while being noninvasive, radiation free, and low cost. Due to th ...
