This paper reports the experimental investigation of the durability of screen printed conductor-based strain gauges on four fabrics of different stiffness by examining the change in the electrical resistances during and after bending. Emphasis is placed on improving the durability of the gauges for both positive and negative bending e-textile applications. The electrical resistance of the print...

The National Institute of Standards and Technology (NIST) has redefined its gas pressure scale, up to 17 MPa, based on two primary standard piston gauges. The primary standard piston gauges are 35.8 mm in diameter and operate from 20 kPa to 1 MPa. Ten secondary standard piston gauges, two each of five series of the Ruska 2465 type, with successively smaller diameters form the scale extending up...

snow cover area is one of the most important criteria to calculate snow melt runoff. this can have an effect on the biology of the plant and the environment of a region. using the catchment basin physical characteristic to calculate snow cover area is a conventional method, though its accuracy is not good enough. most of the useful methods in calculating snow cover area are based on satellite i...

Abstract. Collection efficiency transfer functions that compensate for wind-induced collection loss are presented and evaluated unshielded precipitation gauges. Three novel with wind speed fall velocity dependence developed, including a function from computational fluid dynamics modelling (CFD), an experimental threshold (HE1), linear (HE2). These alongside universal (KUniversal) climate-specif...

Motivated by Schnabl’s gauge choice, we explore open string perturbation theory in gauges where a linear combination of antighost oscillators annihilates the string field. We find that in these linear b-gauges different gauge conditions are needed at different ghost numbers. We derive the full propagator and prove the formal properties which guarantee that the Feynman diagrams reproduce the cor...

Snow cover plays an important role in biotic and abiotic environmental processes, as well human activities, on both regional global scales. Due to the difficulty of situ data collection vast inaccessible areas, use optical satellite imagery represents a useful support for snow mapping. At present, several operational algorithms products are available. Even though most them offer up-to-daily tim...
