This paper proposes a modified glideslope guidance method that optimizes hybrid multiobjective of bearing-only navigation error and fuel consumption. The traditional fixes uniform maneuver intervals the initial approach velocity as predetermined value, making this inflexible. In paper, were used optimization variables, cost function was designed. tradeoff between two objectives analyzed with si...

A good agreement is obtained between experiment and hybrid calculation. Due to structural modelling inaccuracies, the full numerical prediction shows some deviations. However, it appears that a simple BEM model is capable of predicting the general acoustic behaviour of a complex vibrating structure. A sound reduction, specifically in the high frequency range, is obtained with a viscoelastic bea...

We report the development of a catalytic method for the enantioselective addition of indoles to pyrone-derived electrophiles. Arylpyrrolidino-derived thioureas catalyze the addition with high stereoselectivity in the presence of catalytic quantities of an achiral Brønsted acid. The indole-pyrone adducts feature a quaternary stereocenter and represent an unusual class of indolines bearing struct...

A novel hybrid nanoporous material (LNH-1) bearing a tris(propyliminomethyl)-phloroglucinol fluorescent moiety in the framework has been designed and administration of an LNH-1 based drug delivery system containing doxorubicin to cancer cells showed inhibition of proliferation, suggesting its future potential theranostics application in cancer.

The final finishing process of advanced ceramic balls used in hybrid precision bearings constitutes two thirds of the total manufacturing cost, hence the effective and economic finishing methods and processes are critical to their widespread application. A novel eccentric lapping machine is designed and manufactured, Hot Isostatically Pressed (HIPed) silicon nitride ball blanks (diameter 13.25 ...

An investigation is carried out on the systematic analysis of the dynamic behavior of the hybrid squeeze-film damper HSFD mounted a rotor-bearing system with strongly nonlinear oil-film force and nonlinear rub-impact force in the present study. The dynamic orbits of the system are observed using bifurcation diagrams plotted using the dimensionless rotating speed ratio as control parameters. The...

The demand for silent bearing applications has resulted in the development of an effective damping layer between the outer ring of a rolling bearing and the surrounding structure. By means of numerical modeling using both FEM and BEM techniques an induction motor for household appliances is analyzed. A hybrid modeling approach combining measured structural velocities with a BEM formulation is u...

New hybrid POM based on Lindqvist-type polyoxometalates [M6O19](8-) (M = Nb, Ta) and organometallic fragment {Cp*Rh}(2+) have been isolated and characterized. X-ray quality crystals of K4[(Cp*Rh)2Nb6O19]·20H2O () and Cs4[(Cp*Rh)2Ta6O19]·18H2O () were obtained from solutions with {Cp*Rh} : [M6O19](8-) stoichiometry 2 : 1. The solution behavior of the hybrid polyoxoanions was studied with ESI-MS ...

A strategy to target functionalized quantum dot-liposome (f-QD-L) hybrid vesicles in the solid tumor tissue of tumor-bearing mice is explored. Functionalized polyethylene glycol (PEG)-lipid coated QD (f-QD) were encapsulated into the aqueous core of 100 nm cationic (DOPC:Chol: DOTAP); sterically stabilized, fluid-phase (DOPC:Chol:DSPE-PEG2000); and sterically stabilized, gel-phase (DSPC:Chol:DS...
