Development of the correction procedure for High Volume Instrument elongation measurement. [PDF]

open access: yesTextile Research Journal, 2020
Cotton spinning mills need high-quality fibers to maintain their manufacturing efficiency. Machinery throughput is increasing and it could translate into more processes with higher breaking stress. Consequently, more fibers are susceptible to breaking or

Limits of measuring short fiber content by high volume instrument [PDF]

open access: yes, 2004
Many attempts are currently ongoing to measure or estimate the short fiber content in raw cotton by High Volume Instrument (HVI). Up to now, a fiber is considered "short" if its length is lower than 12,7 mm, even if it is not proven that this is the most

A cavity-enhanced ultraviolet absorption instrument for high-precision, fast-time-response ozone measurements [PDF]

open access: yesAtmospheric Measurement Techniques, 2020
The NASA Rapid Ozone Experiment (ROZE) is a broadband cavity-enhanced UV (ultraviolet) absorption instrument for the detection of in situ ozone (O3). ROZE uses an incoherent LED (light-emitting diode) light source coupled to a high-finesse optical cavity

Assessing Multi-Temporal Snow-Volume Trends in High Mountain Asia From 1987 to 2016 Using High-Resolution Passive Microwave Data

open access: yesFrontiers in Earth Science, 2020
High Mountain Asia (HMA) is dependent upon both the amount and timing of snow and glacier meltwater. Previous model studies and coarse resolution (0.25° × 0.25°, ∼25 km × 25 km) passive microwave assessments of trends in the volume and timing of snowfall,
