A constant cross-section wind tunnel usually experiences a negative pressure gradient (ie, favorable gradient, FPG), resulting in certain degree of discrepancy between the simulated and idealized atmospheric boundary layer (ABL) flows. To investigate its impact, three large-eddy simulation (LES) cases were conducted this study: one simply reproduced tunnel, removed FPG by adjusting ceiling heig...

The theory of tunnel current-voltage (I-V ) characteristics of metal-semiconductor junctions based on the self-consistent solution of Poisson equation allows to get the Schottky-barrier height and the charged impurity concentration directly from the tunneling data. This approach was applied to the analysis of the low temperature experiments on tunneling under pressure up to 3GPa in a piston-cyl...

The only documentation on the building downwash algorithm in AERMOD (American Meteorological Society/U.S. Environmental Protection Agency Regulatory Model), referred to as PRIME (Plume Rise Model Enhancements), is found in the 2000 A&WMA journal article by Schulman, Strimaitis and Scire. Recent field and wind tunnel studies have shown that AERMOD can overpredict concentrations by factors of 2 t...

A new tunnel tube crossing the river Elbe has been built in Hamburg until the end of 2002. Therefore, a new height control system was required. A computer examines the signals from light barriers and overhead sensors to detect vehicles, which try to drive into a tube with insufficient height. If necessary, it raises an alarm that blocks the road. This paper describes the application of two safe...

An improved process for graphene transfer was used to demonstrate high performance graphene enabled vertical organic field effect transistors (G-VFETs). The process reduces disorder and eliminates the polymeric residue that typically plagues transferred films. The method also allows for purposely creating pores in the graphene of a controlled areal density. Transconductance observed in G-VFETs ...

Deep rock engineering is in a high pre-stressed state before excavation. In this research, method to calculate the release of strain energy caused by excavation proposed. The normal stress after leads reduction specimens. influence height and width on inconsistent under vertical loading. When hole 1 mm, large, increase slow release. very small, an increasingly faster energy. This exponentially ...

BACKGROUND/AIM With the evolving boundaries of sports science and greater understanding of the driving factors in the human performance physiology, one of the limiting factors has now become the technology. The growing scientific interest on the practical application of hypoxic training for intermittent activities such as team and racket sports legitimises the development of innovative technolo...

Noonan syndrome (NS) is a common, predominantly inherited condition characterized by distinctive facial features, short stature, chest deformity, heart disease, and often other disease manifestations. Approximately 61% of NS cases can be explained by changes in the genetic make-up, the reason behind the remaining 39% is mostly unknown. Thus, NS frequently remains a clinical diagnosis. Because o...
