Abstract In this paper, a sliding mode (SM)-based online fault compensation control scheme is investigated for modular reconfigurable robots (MRRs) with actuator failures via adaptive dynamic programming. It consists of SM-based iterative controller, an robust term and compensator. For fault-free MRR systems, the SM surface-based Hamilton–Jacobi–Bellman equation solved by policy iteration algor...

Non linear antiferromagnetic resonance was observed by parallel pumping (PP) with continuous waves in (NHsCH~)~ CuC14. This system is unique in its low threshold for PP and its strong anisotropy. The absorbed microwave power displays self spiking. As a function of power the irregularity of periods between the spikes changes. Reproducible transitions from nearly regular to irregular spiking are ...

The dual power flow wind energy conversion system (DPF-WECS) is a novel system which is based on the electrical variable transmission (EVT) machine. The proposed sensorless control for the DPF-WECS is based on the model reference adaptive system (MRAS) observer by combining the sliding mode (SM) theory. The SM-MRAS observer is on account of the calculations without the requirement of the propor...

In the absence of natural avor conservation, multi-Higgs doublet models generally contain new sources of CP violation and anomalous charged Higgs Yukawa couplings. We present a chargedHiggs CP violation study of one such two-Higgs doublet model (2HDM) which treats the top quark di erently from the other quarks. The phenomenological implications for the K K system and for B decays di er signi ca...

Estimation precision and bandwidth of sliding mode (SM) observers are analyzed in the frequency domain for different settings of the observer design parameters. It was shown previously that the SM observer could be analyzed as a relay feedback-feedforward system. It is feedback with respect to the measured variable of the system being observed, and feedforward with respect to the control applie...

We demonstrate efficient multimode (MM) to single-mode (SM) conversion in a 19-port photonic lantern with a 50 μm core MM delivery fiber. The photonic lantern can be used within the field of astrophotonics for coupling MM starlight to an ensemble of SM fibers in order to perform fiber-Bragg-grating-based spectral filtering. An MM delivery fiber spliced to the photonic lantern offers the advanta...

The effects of rare earth elements (La, Sm) on the high-temperature (250 °C) microstructure and mechanical properties Al-Si-Cu alloys were analyzed. experimental results show that with addition La Sm, α-Al was significantly refined, eutectic Si changed from acicular to rod-like granular. XRD SEM analysis shows phases in alloy mainly AlSiRe AlRe. Fracture morphology observations fracture mode ch...

In the few studies that have been conducted, researchers have typically found that deaf adolescents have more mental health difficulties than their hearing peers and that, within the deaf groups, those who use spoken language have better mental health functioning than those who use sign language. This study investigated the hypotheses that mental health functioning in adolescence is related to ...

Sec1/Munc18 (SM) family proteins are essential for every vesicle fusion pathway. The best-characterized SM protein is the synaptic factor Munc18-1, but it remains unclear whether its functions represent conserved mechanisms of SM proteins or specialized activities in neurotransmitter release. To address this question, we dissected Munc18c, a functionally distinct SM protein involved in nonsynap...

In the framework of R-parity violating (Rp / ) supersymmetry, we try to find a consistent explanation for both recently measured CP asymmetry in B0 → φKS decay and the large branching ratio of B → ηK decay, which are inconsistent with the Standard Model (SM) prediction. We also investigate other charmless hadronic B → PP and B → V P decay modes whose experimental data favor the SM: for instance...
