conclusions results suggest that these methods cannot be interchanged, and vvi showed significantly lower lv peak twist, peak twisting rate and peak untwisting rate. however, when lv twist and lv twisting rates were normalized to lv length, values were comparable for both imaging techniques. results twist degree was significantly lower in the vvi group than in the tdi group (p = 0.008, r = 0.56...

This paper deals with the modelling and control of differential steering for vehicular motions help Sliding Mode Control (SMC) a Super-Twisting Algorithm (STA). A single-track mechanical model dynamics is proposed validated by simulations. strategy based on STA yaw to improve travel comfort stability motion. The desired trajectory given equivalent corrective parts are calculated controller. Sim...

Bu makalede, 9 seviyeli Paket E-Hücreli eviriciler için üstün burulma algoritması tabanlı bir kayan kipli kontrol yöntemi sunulmuştur. Şebekeden bağımsız eviricilerin kontrolünde temel amaç, yük gerilimini regüle etmektedir. amaca ulaşmak öncelikle kontrolör tasarlanmıştır. Kayan yönteminin çıkışı değişken anahtarlama frekansına neden olan çatırtı sorunları içermektedir. Çatırtı etkisini azaltm...

Aiming at the unknown uncertainty of an active power filter system in practical operation, combining advantages self-feedback structure, interval type-2 fuzzy neural network, and super-twisting sliding mode, adaptive mode control method network with recursive structure (IT2FNN-SFR STSMC) is proposed this paper. IT2FNN has uncertain membership function, which can enhance nonlinear ability robust...

We introduce the concept of pseudotwistor (with particular cases called twistor and braided twistor) for an algebra (A,μ, u) in a monoidal category, as a morphism T : A⊗ A → A ⊗ A satisfying a list of axioms ensuring that (A,μ ◦ T, u) is also an algebra in the category. This concept provides a unifying framework for various deformed (or twisted) algebras from the literature, such as twisted ten...

The scenery of the nucleus The nucleoplasm is no less dense, even though it contains neither membrane nor rigid filament. However, it contains one remarkable type of filament, the DNA, which, for a mammalian cell with a small nucleus, can account for close to 10% (100 mg m1-1) of the nuclear mass (including water). This is a very high concentration much higher than that generally used for exper...
