Self-Anti-Disturbance Control of a Hydraulic System Subjected to Variable Static Loads

open access: yesApplied Sciences, 2022
A hydraulic system’s lubricating oil is subject to serialized variable static loads with performance. An improved self-turbulent flow algorithm, based on the real-time acquisition and monitoring of lubricating oil static pressure in a hydraulic system to

THE PRELIMINARY ANALYSIS OF DISTRIBUTION OF THE VELOCITY FIELD AND AIR PRESSURE FLOWING THROUGHT THE MINING HEADINGS WITH DIFFERENT GEOMETRY OF CROSS‐SECTION [PDF]

open access: yesManagement Systems in Production Engineering, 2013
The basic meaning for the security of persons working in underground mining heading heir ventilation of headings. Providing the fresh air into the active mining heading is a fundamental task of ventilation service in the mine.

Cavitation Risk through the Bottom Outlet of the Dam Using Numerical Solution of Ansys Model

open access: yesعلوم آب و خاک, 2022
The objective of the present research was to investigate the flow properties through the bottom outlet of the Nesa dam based on numerical and experimental studies. 22 piezometers were employed to measure the static pressure through the experimental model.

Relationship between hyperacute blood pressure and outcome after ischemic stroke: data from the VISTA Collaboration [PDF]

open access: yes, 2009
Background and Purpose—High blood pressure (BP) is associated independently with poor outcome after acute ischemic stroke, although in most analyses “baseline” BP was measured 24 hours or more postictus, and not during the hyperacute period.

Sensorless Air Flow Control in an HVAC System through Deep Learning

open access: yesApplied Sciences, 2019
Sensor-based intelligence is essential in future smart buildings, but the benefits of increasing the number of sensors come at a cost. First, purchasing the sensors themselves can incur non-negligible costs.

Static pressure seal of earmolds

open access: yesThe Journal of Rehabilitation Research and Development, 1990
Four experiments were carried out to investigate the effect on the static pressure seal of earmolds made from currently used impression and earmold materials; the occasional practice of making more than one earmold from an impression; the earmoldmaker buildup of impressions; and the multistage buildup of impressions by the impression taker.

Static pressure measurements of enclosure fires

open access: yesJournal of Research of the National Bureau of Standards, 1977
Some enclosure-fire static pressure measurements are presented for both full and scale model rooms and are compared with the present hydraulics-orifice flow model for fire induced flows into and out of enclosures. Results indicate that the vertical pressure differential (enclosure to ambient) follows the expected hydrostatic distribution quite well and

Effectiveness of a Novel Low‐Density Lipoprotein Apheresis Device Rheocarna in Patients Undergoing Hemodialysis With Chronic Limb‐Threatening Ischemia: A Single‐Center Retrospective Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic limb‐threatening ischemia (CLTI) is a severe form of lower‐extremity artery disease characterized by distal lesions and microcirculatory impairment, limiting revascularization efficacy. Rheocarna is a direct hemoperfusion low‐density lipoprotein (LDL) adsorption device with potential rheological and anti‐inflammatory ...
