Single-hit resolution measurement with MEG II drift chamber prototypes [PDF]

, 2016
Drift chambers operated with helium-based gas mixtures represent a common solution for tracking charged particles keeping the material budget in the sensitive volume to a minimum.

Speed Control of Induction Machine Based on Matrix Converter with Unbalanced Input Voltage [PDF]

Journal of Intelligent Procedures in Electrical Technology, 2011
Matrix Converter (MC) is a direct energy conversion device with high input power factor. As a device without dc link elements, its output characteristic and reliability can be degraded by ac line side disturbances.

The maximum mass of planetary embryos formed in core-accretion models [PDF]

, 2017
We compute the maximum mass a growing planetary embryo can reach depending on the size of accreted planetesimals or pebbles, to infer the possibility of growing the cores of giant planets, and giant planets themselves.

Using Deep Neural Networks to compute the mass of forming planets

, 2019
Computing the mass of planetary envelopes and the critical mass beyond which planets accrete gas in a runaway fashion is important when studying planet formation, in particular for planets up to the Neptune mass range.

Mitigation of microbunching instability in x-ray free electron laser linacs [PDF]

, 2020
The microbunching instability seeded by small initial density modulation and driven by collective effects can cause significant electron beam quality degradation in next generation x-ray free electron lasers.

Scalar Control for Six Phase Matrix Converter Fed Double Star Induction Motor

Advances in Electrical and Computer Engineering, 2010
Two different control strategies applied to a direct AC-AC six phase matrix converter are investigated in the present paper. The first strategy is derived from the Venturini method and the second approach is practically an extension of the scalar ...

Gas and Dust in the Cloverleaf Quasar at Redshift 2.5

, 2003
We observed the upper fine structure line of neutral carbon, CI(2-1), the CO(3-2) line and the 1.2mm continuum emission from H1413+117 (Cloverleaf quasar, z=2.5) using the IRAM interferometer. Together with the detection of the lower fine structure line (
