In this paper, an H∞ control strategy is implemented in a prototype alkaline electrolyzer to maintain equalized the liquid levels in the separations chambers while following a pressure reference. The aim is to minimize...

Abstract This study investigated the effects of pressure-mediated protein changes on the ice nucleation temperature of pork loins. To variate chemical state of meat proteins, pork loin was pressurized at varying pressure...

Pressure coefficients due to wind in open canopy structures with parapets, such as those commonly used in gas stations, are presented. Two independent methodologies were used to obtain pressure coefficients: wind tunnel ...

Abstract Currently, a 2-port microwave transmission line with a glass window is usually used to transmit microwave energy to a pressure vessel while sealing the high-pressure gas. In this situation, the damage of the bri...

The technology of borehole pressure relief is an effective way to reduce the elastic energy accumulation in the surrounding rock of roadways, which can reduce the risk of regional rock bursts. Therefore, the studies on t...

This study proposes a deep-hole directional blasting technology based on polymer energy charge packages for roof cutting and pressure relief as a solution to difficult roadway support and poor stability of coal pillars d...

Abstract Current research on pilot-operated relief valve stability is primarily conducted from the perspective of system dynamics or stability criteria, and most of the existing conclusions focus on the spool shape, damp...

Abstract An overview is given of investigations on a 70° slender delta wing applying pressure-sensitive paint (PSP) and particle image velocimetry (PIV) in parallel. Experiments are conducted within the range of Reynold...

High-voltage cable systems are critical components of power transmission networks, where partial discharge (PD) can cause insulation degradation and severe operational failures. Accurate detection and reliable identifica...

Multiple studies had been conducted to improve the geological understanding and enrichment patterns of the Wufeng-Longmaxi Formation in the southeastern Sichuan Basin’s complex tectonic belt. However, the influence of ...

Abstract In this paper, the unsteady flow around a high-speed train is numerically simulated by detached eddy simulation method (DES), and the far-field noise is predicted using the Ffowcs Williams-Hawkings (FW-H) acoust...

Base pressure plays a vital role in aerospace-related applications and its control is essential in reduction of drag and improving fuel consumption. Low pressure at the base of Rockets, Missiles, bombs and shells are a v...

Zirconium alloys in nuclear power plants operate in high-pressure water at temperatures between 250 and 350 °C. Hydrogen (or deuterium) ingress due to waterside corrosion and if the solubility is exceeded H precipitates...

Abstract Currently, the measurement methods for pneumatic system leakage include bubbling, ultrasonic, and pressure detection methods. These methods are sensitive to high-precision sensors, long detection times, and stab...

Complex interactions between seawater and freshwater govern intrusion and stabilization in coastal aquifers. Previous studies have primarily relied on interface-based analyses, limiting full-field spatial quantification ...

Environmental and health concerns about lead-based materials have increased the need for high-density, lead-free alternatives for fishing weights, hunting bullets, ammunition, and body armor applications. Brass/40 wt.%...

The kinetics of ammonia oxidation with oxygen over a Rh(110) surface were studied in the pressure range 10-5 –10-4 mbar. Nitrogen was found to be the preferred product at low partial pressures ratios po2 : pNH3 , while...

Abstract Modern broadband access networks increasingly carry heterogeneous, delay-sensitive traffic generated by cloud-assisted applications, real-time communication services, and short-form multimedia exchanges. These w...

Abstract While the ultra‐low velocity zones (ULVZs) may hold key information about deep Earth dynamics, their elusive state and origin remain enigmatic. Recent high‐pressure experiments suggest that ULVZs may origina...

Abstract In current research on deflector jet servo valves, the receiver pressure estimated using traditional two-dimensional simulation and theoretical calculation is always lower than the experimental data; therefore, ...

Abstract Rice-based cropping systems remain dominant in Bangladesh’s agricultural landscape, yet their long-term sustainability and profitability are increasingly constrained by high input requirements, ecological pres...

The relative-rate technique has been used to obtain the rate coefficients for the reactions of the saturated aldehydes (SA): Octanal (OCT) CH3(CH2)6C(O)H and Nonanal (NON) CH3(CH2)7C(O)H with OH radicals and Cl atoms at ...

Abstract Attachment security priming has shown promise in reducing anxiety in controlled experiments, yet its application and effectiveness in real-world educational settings remain underexplored. This study investigated...

Fine-scale heterogeneity in soil nutrient availability can enhance plant growth, yet its effect across soil depth remains inadequately understood. Communities with increased species diversity showed varying growth strate...
