Dark Energy Survey Year 1 Results: A Precise H-0 Estimate from DES Y1, BAO, and D/H Data

Juan Andrei Villarroel Fernandez, Eduardo Sanchez, Craig Matthew Smith, Aaron James Rossini, Augusto Martins Lima, Jonathan Andrew Blazek

We combine Dark Energy Survey Year 1 clustering and weak lensing data with baryon acoustic oscillations and Big Bang nucleosynthesis experiments to constrain the Hubble constant. Assuming a flat Lambda CDM model with minimal neutrino mass (Sigma m(v), = 0. ...

DES Y1 Results: validating cosmological parameter estimation using simulated Dark Energy Surveys

Eduardo Sanchez, Mingkui Wang, Craig Matthew Smith, Augusto Martins Lima, Jonathan Andrew Blazek

We use mock galaxy survey simulations designed to resemble the Dark Energy Survey Year 1 (DES Y1) data to validate and inform cosmological parameter estimation. When similar analysis tools are applied to both simulations and real survey data, they provide ...

On the Design of a Fault Tolerant Ripple-Carry Adder with Controllable-Polarity Transistors

Eduardo Sanchez, Giovanni De Micheli, Hassan Ghasemzadeh Mohammadi, Jian Zhang, Pierre-Emmanuel Julien Marc Gaillardon

This paper first explores the effects of faults on circuits implemented with controllable-polarity transistors. We propose a new fault model that suits the characteristics of these devices, and report the results of a SPICE-based analysis of the effects of ...
