Method of Acoustic Calculation of Traffic Noise Barriers [PDF]

open access: yesMATEC Web of Conferences, 2020
Installation of noise barriers is an efficient and relatively cheap way of protecting residential areas from traffic noise. This paper proposes a comprehensive method of calculation of noise barriers.

Direct barrier evaluation method for SiC devices with junction barrier Schottky structures demonstrated with quasi-continuous spacing variation

open access: yesAIP Advances, 2022
Junction barrier Schottky (JBS) structures are extensively used in silicon carbide devices; however, the complex surface composition makes the direct barrier evaluation difficult.

The renaissance of barrier methods [PDF]

open access: yesJournal of Family Planning and Reproductive Health Care, 2012
In 1987, the threat of litigation led to the withdrawal of intrauterine devices (IUDs)from the American market where depot medroxyprogesterone acetate (DMPA)had already been banned. There were fears of repercussions that would have led to the limiting of contraceptive choice in Britain.

Na+/K+-ATPase α1 identified as an abundant protein in the blood-labyrinth barrier that plays an essential role in the barrier integrity. [PDF]

open access: yesPLoS ONE, 2011
BACKGROUND:The endothelial-blood/tissue barrier is critical for maintaining tissue homeostasis. The ear harbors a unique endothelial-blood/tissue barrier which we term "blood-labyrinth-barrier".

A boundary element method for the calculation of noise barrier insertion loss in the presence of atmospheric turbulence [PDF]

open access: yes, 2004
Atmospheric turbulence is an important factor that limits the amount of attenuation a barrier can provide in the outdoor environment. It is therefore important to develop a reliable method to predict its effect on barrier performance.

A Framework for Worst-Case and Stochastic Safety Verification Using Barrier Certificates [PDF]

open access: yes, 2007
This paper presents a methodology for safety verification of continuous and hybrid systems in the worst-case and stochastic settings. In the worst-case setting, a function of state termed barrier certificate is used to certify that all trajectories of ...

Fusion at deep subbarrier energies: potential inversion revisited [PDF]

open access: yes, 2008
For a single potential barrier, the barrier penetrability can be inverted based on the WKB approximation to yield the barrier thickness. We apply this method to heavy-ion fusion reactions at energies well below the Coulomb barrier and directly determine ...
