Vibrations are among main causes of fatigue and damages leading to destruction of rotating blades. Consequently, motions of blades have to be carefully studied, and in particular, periodic components. Blade Tip-Timing (BTT) methods achieve non-intrusive measurements which is a great advantage with respect to classical methods. They can be modelled by a Periodic Nonuniform Sampling of order L eq...

A new autopilot design for bank-to-turn (BTT) missiles is presented. In the design of autopilot, a ridge Gaussian neural network with local learning capability and fewer tuning parameters than Gaussian neural networks is proposed to model the controlled nonlinear systems. We prove that the proposed ridge Gaussian neural network, which can be a universal approximator, equals the expansions of ro...

BACKGROUND : With the development of visceral obesity, against background insulin resistance (IR), lipo- and glucose toxicity in tissues progresses, which disrupts metabolic balance body, is main factor type 2 diabetes mellitus (DM2). To date, a growing number publications highlighting role circadian rhythms control gluconeogenesis lipogenesis. In context DM2, process rhythm mismatch (desynchro...

PurposeIn the new heart transplant (HT) allocation system patients, (pts) with durable left ventricular assist device (LVAD) have worse outcomes. Donor hearts are allocated to recipients according pre-specified criteria (urgency, blood type, size, HLA profile, etc). If an organ is not accepted by selected center it will be offered next center. Unsuitable organs may rejected multiple centers. We...

m C c m r f t i t p ogers et al. (1) describe in this issue of the Journal the argest report of functional capacity and quality of life to ate in patients implanted with a continuous flow left entricular assist device (LVAD). Patients were implanted or 2 indications: bridge to transplant (BTT) (n 281) and estination therapy (DT) (n 374). The authors conclude hat both mortality reduction, improv...

Use of the tritopic bridging ligand 1,3,5-benzenetristetrazolate (BTT3-) enables formation of [Mn(DMF)6]3[(Mn4Cl)3(BTT)8(H2O)12]2.42DMF.11H2O.20CH3OH, featuring a porous metal-organic framework with a previously unknown cubic topology. Crystals of the compound remain intact upon desolvation and show a total H2 uptake of 6.9 wt % at 77 K and 90 bar, which at 60 g H2/L provides a storage density ...

The backstepping design method has been used to design the control system of the Bank-to-turn (BTT) missile, which depends on the designer’s personal experience and a large number of complicated iterative calculation, and needs to consume a lot of time throughout the design process. To solve this problem, a missile control system surrogate model is established by using Kriging meta-model. After...
