Resumen
Video compression relies heavily on exploiting the temporal redundancy between video frames, which is usually achieved by estimating and using the motion information. The motion information is represented as optical flows in most of the existing deep video compression networks. Indeed, these networks often adopt pre-trained optical flow estimation networks for motion estimation. The optical flows, however, may be less suitable for video compression due to the following two factors. First, the optical flow estimation networks were trained to perform inter-frame prediction as accurately as possi

Resumen
We studied the effect of mild external leg compression on both skin and muscle microvascular flow, and muscle oxygenation in the leg of healthy subjects during simulated venous hypertension. Skin and muscle microvascular blood flows were measured using photoplethysmography (PPG), and muscle oxygenation was measured using near-infrared spectroscopy (NIRS). Both PPG and NIRS probes were placed over the anterior compartment of the right leg in 8 healthy subjects. Measurements were taken under three experimental conditions: external leg compression (40 mmHg); simulated venous hypertension (65 mmHg

Resumen
In this study, to analyze the effect of wet compression technology on the aero-thermodynamic performance of a centrifugal compressor, a numerical analysis study was conducted on the design point and off-design point. Wet compression technology sprays water droplets at the inlet of the compressor. During the compression process, water droplets evaporate, reducing the heat of compression and reducing the compression work, which improves the efficiency of the compressor. In wet compression technology, detailed research is needed for the application to compressors because the droplet behavior affe

Resumen
A study is made here of the application of a differential stress model (DSM) of turbulence to flows in two model reciprocating engines. For the first time this study includes compressive effects. An assessment between DSM and k-ɛ results is made comparing with laser Doppler anemometry experimental data of the mean flow and turbulence intensity levels during intake and compression strokes. A well-established two-dimensional finite-volume computer code is employed. Two discretization schemes are used, namely the HYBRID scheme and the QUICK scheme. The latter is found to be essential if different

A model of dynamics of the vapor bubbles that emerge on solid surfaces of porous structures and the steam generating wall (bottom layer) is presented in this work. The model was filmed and photographed by a high-speed camera SKS-1М. The discharge of high heat flows (up to 2·106 W/m2) was maintained by the joint action of capillary and mass forces with the help of intensifiers. An analytical model was developed based on the theory of thermoelasticity. The limit state of the porous coating with poor thermal conductivity and the metal bottom layer was determined.

The use of compression flows (CPF) for the formation of metal and silicide nanostructures for data storage devices, thermoelectric materials and solar cells is presented. The action of CPF with injected metallic powder results in the formation of coatings composed of spherical clusters with complex structure: each submicron cluster (0,1-0,2 μm radius) is formed from a number of nanosized ones (10-25 nm radius). The action of CPF on binary “metal-silicon” systems provides formation of branched silicon dendrites (tip radius ~ 200 nm, primary spacing ~ 1,2 μm); interdendritic space is filled w

Results were com¬pared to experimental data and the results of simulations performed with standard turbulence models.

Transmission and storage operations frequently move natural gas using reciprocating compressors that may generate flow pulsations. Most measurement systems cannot accurately measure the flow rate of a pulsating gas stream, and the resulting errors can cause inaccurate gas volumes and accounting imbalances. Recent advances in ultrasonic meters may provide the ability to function without measurement error in pulsating gas streams. Tests were performed to examine the relationship between ultrasonic meter transducer sampling rates, the frequency and amplitude of pulsations from reciprocating compr

Resumen
Measurement of the throughput of a natural gas compressor can be undertaken using a constant flow tracer dilution technique. In this technique, a constant flow of tracer is introduced into the piping upstream of the compressor while samples of diluted tracer are measured downstream of the compressor. The samples are analyzed using a specially configured analyzer. Knowledge of the injection rate and injection concentration coupled with the downstream measurement of tracer concentration allows the throughput through the compressor to be calculated. Under this contract, three systems were fabrica

Resumen
Evaluates the impact of heat transfer on reciprocating compressor performance, especially with respect to flow capacity. This paper gives results of the experimental measurements done to determine the contribution of regenerative heat transfer to suction gas heating and its comparison with earlier empirical models. It forms part of ongoing research on estimating the effects of heat transfer on compressor performance with a view to modeling such effects for improved prediction of compressor performance.

Resumen
The objectives of this research are to develop methods for performing ultrasonic flow meter (USM) diagnostic evaluation automatically and a software tool with all necessary attachments. USM-based diagnostics have been established and thirteen categories of knowledge rules of existing cases have been learned and integrated. A search engine for relevant standards, specifications, and other documents of the measurement system has been developed, which enables the free search of text content. Further, with the assistance of modern reasoning techniques, the authorized user only needs to configure a

Resumen
At natural gas pipeline compressor stations, methane emissions from compressor and engine crankcases are often vented directly into the atmosphere. There may be advantages to capturing these emissions and using them to offset fuel usage and / or decrease the overall carbon footprint of such a typical compressor station. This study evaluates the feasibility of directing such captured emissions into the intake of the compressor engine and subsequently combusting the methane emissions into carbon dioxide and water. Although seemingly an obvious or trivial solution, there are in fact several chall
