Constrained Nonlinear Predictive Control of Gasoline Low-Temperature Combustion — Combustion of a gasoline fuel with a high amount of recirculated exhaust gas is increasingly gaining interest. Such in part load conditions, a low combustion peak temperature can be achieved, which yields lowest emissions but suffers from instabilities of the process and a highly nonlinear behavior. These properti...

SLJMMARY A rectangular intake having variable geometry compression surfaces and designed for supersonic operation has been tested at a Mach number of 0.9 and a Reynolds number based on intake entry height of approximately 106. Tests have been made on the intake in isolation and on the side of a fuselage. Maximum mass flow is less than estimates based on geometric throat size. The deficit corres...

The subject matter of the article is process subsonic air intake shaping for gas-turbine engines at airplane preliminarily design stage. goal to develop a mathematical model non-circular on base V. I. Polikovskii method high-bypass ratio turbofan. tasks be solved are: consider possibility shape external outline engine nacelle; take into account internal duct (in first approximation, cross-secti...

Background: End-stage renal disease (ESRD) and replacement therapy options are associated with malnutrition, which occurs in 30-50% of patients. Suboptimal nutritional status physical inactivity common peritoneal dialysis patients also consequences the restrictive diet, appetite loss, poor fitness. Materials methods: This single-center observational study aimed to analyze dietary intake, body c...

In recent years, installation of plates in canal beds have been considered for sedimentation control and bed load reduction at canal intake. These planes, called submerged vanes, are different in dimensions. They are installed at intakes in-group with reasonable distance from each other. Presence of these vanes at intakes initiate transverse shear stress on river bed and causes sediment transpo...

purpose: to evaluate visual outcomes and intraocular pressure (iop) after single-site phacotrabeculectomy with mitomycin c in patients with senile cataract and primary open angle glaucoma (poag), pseudoexfoliative glaucoma (pxg), or chronic angle closure glaucoma (cacg). methods: in this retrospective study, patients older than 50 years who had significant cataracts (bcva £ 20/60) and uncontrol...

The intake port of a CA4DD diesel engine was investigated by computational fluid dynamics (CFD) numerical simulation to enhance the swirl and improve flow characteristics in engine. uniform design method applied study influence guide vanes with different parameters on process at various valve lifts. Nine vane models were established compared base model using CATIA™ 3D CAD software. Numerical si...
