State Primary Standard GET 200–2012 of the units of measurement of volumes of digital information transmitted via Internet and by telephone is described. A method of generation of reference files is ...set forth. A technique of estimating the integrity of reference files is proposed.
Volcanic lakes are unique ecosystems with complex relationships between atmospheric variables and crater lake dynamics. In two adjacent tropical, high mountain lakes, spectral analysis of coupled in ...situ meteorological and hydrodynamic measurements revealed strong diurnal fluctuations in water temperature due to wind-forced internal gravity waves and free seiche oscillations. Although the amplitudes of these internal motions were small, they contribute to the transfer of momentum and mixing, with large potential impacts on lake productivity. During daytime heating, in both lakes, a thermocline formed in the near-surface layer (2−3 m depth) but eroded at night. The heat penetration into each lake within the crater differed significantly, even though they were ∼ 500 m apart, driven by differences in water transparency and algal growth. Analyses of coupling between local meteorology and lake hydrodynamics revealed complex forcing of small-scale patterns which are important to incorporate into future studies to understand how ecosystem productivity is modulated.
A microfluidic device designated for measurement of fluidic flows with different viscosity, necessary within trapping/realising of cells/particles system has been developed. We use a new concept as ...Microfluidic Pulse Width Modulation (MPWM) for controlling transport of a single cell/particle. The image processing helped the nano-hydraulic volumes/flow rates measurement, through tracking inovative methods with the purpose to build a flow sensor. The device open an unique opportunitie for single cell study with applications in biomedical devices, tools for biochemistry or analytical systems.
The volume of a tank from the formulations in the State Primary Special Standard of the unit of the volume and mass flow rate of water GET 119–2010 is measured by means of 3D laser scanning. A ...comparative analysis of reference data and measurement results is presented. The error caused by software processing of the results of scanning is estimated.
