Effects of weak anchoring on C1 and C2 chevron structures [PDF]
, 2005 We present a theoretical study of the effect of weak anchoring on the transition between C1 and C2 chevron structures in smectic C liquid crystals. We employ a continuum theory which allows for variable cone, azimuthal and layer tilt angles.

Modelling of tilt rotor mission performance to assess environmental impact [PDF]
, 2012 New technologies and new rotorcraft operations are being developed in order to meet new environmental requirements such as noise reduction and less pollutant emissions. In this project a parametric study was developed over a tilt rotor model in order to

Segregation mechanism of arsenic dopants at grain boundaries in silicon
Science and Technology of Advanced Materials: Methods, 2021 Three-dimensional distribution of arsenic (As) dopants at Σ3{111}, Σ9{221}, Σ9{114}, and Σ9{111}/{115} grain boundaries (GBs) in silicon (Si) is examined by correlative analytical methods using atom probe tomography (APT) combined with low-temperature ...

Re-examining sunspot tilt angle to include anti-Hale statistics [PDF]
, 2014 Sunspot groups and bipolar magnetic regions (BMRs) serve as an observational diagnostic of the solar cycle. We use Debrecen Photohelographic Data (DPD) from 1974-2014 that determined sunspot tilt angles from daily white light observations, and data ...
