This paper present work on modern control approaches in titling railway vehicles. The design of the Linear Quadratic Gaussian with integral action controller provides the required tilt compensation, while the addition of the fuzzy mechanism to the controller improves the system performance both for the deterministic and stochastic track. Moreover, the use of multiobjective GA as a tuning method...

Abstract—In this work a dynamic model of a new quadrotor aerial vehicle that is equipped with a tilt-wing mechanism is presented. The vehicle has the capabilities of vertical take-off/landing (VTOL) like a helicopter and flying horizontal like an airplane. Dynamic model of the vehicle is derived both for vertical and horizontal flight modes using Newton-Euler formulation. An LQR controller for ...

OBJECTIVE To investigate the haemodynamic effects of varying the angle of head up tilt. METHODS 20 healthy subjects (12 female, eight male; mean (SD) age 33.6 (8.4) years) underwent head up tilt for five minutes to each of four angles of tilt in random order, with a five minute rest period at the horizontal between each angle. Forearm blood flow was measured using intermittent occlusion mercu...

One of the major methodological challenges in single particle electron microscopy is obtaining initial reconstructions which represent the structural heterogeneity of the dataset. Random Conical Tilt and Orthogonal Tilt Reconstruction techniques in combination with 3D alignment and classification can be used to obtain initial low-resolution reconstructions which represent the full range of stru...

The mechanosensitive channel of large conductance (MscL) serves as a model system for mechanosensitive ion channels gated by the bilayer mechanism. Here we report our measurements of the distance changes of multiple residues of MscL using smFRET. These measurements were then used to develop a molecular dynamics model for the open structure of the protein. We find that its open pore size is 2.8 ...

The vestibular system is known to have an important role in controlling blood pressure upon posture transition (vestibulo-cardiovascular reflex, VCR). However, under a different gravitational environment, the sensitivity of the vestibular system may be altered. Thus, the VCR may become less sensitive after spaceflight because of orthostatic intolerance potentially induced by long-term exposure ...

The prevalence of allergic-related diseases, food intolerance, and chemical sensitivities in both the pediatric and adult population has increased dramatically over the last two decades, with escalating rates of associated morbidity. Conditions of acquired allergy, food intolerance and chemical hypersensitivity are frequently the direct sequelae of a toxicant induced loss of tolerance (TILT) in...

Ever since the introduction of products such as the Nintendo Wii or the Nokia N95, motion-based interaction has become en vogue in research and industry alike. The employment of this new form of interaction is the subject of extensive research, especially for mobile use. Tilt or gesture interaction allow for quick and intuitive manipulation since the device is already at hand. So far there is n...

Condensation surface modification was an important research direction to realize droprise condensation and erhance heat transfer. In order explore the process mechanism of droplets on hydrophobic surface, natural Donghu lotus leaves with tilt angle 30°,60° 90° were studied. The results show that had a significant effect behavior surface. Increasing would short detachment time condensate droplet...
