For some disturbances and model uncertainties of the multi-tank level system, we develop an adaptive nonlinear control law based on the neural network to achieve high performance control. A nonlinear model including the model uncertainties and disturbances is firstly built through carefully analyzing the multi-tank level system. Based on the model, the level controller is designed, in which the...

Speedmeters are known to be quantum non-demolition devices and, by potentially providing sensitivity beyond the standard quantum limit, become interesting for third generation gravitational wave detectors. Here we introduce a new configuration, the sloshing-Sagnac interferometer, and compare it to the more established ring-Sagnac interferometer. The sloshing-Sagnac interferometer is designed to...

An articulated covered wagon design was developed. The feature is that the body-bearing elements are made of circular pipes. This technical solution it possible to reduce tare weight while ensuring strength conditions. Mathematical simulation dynamic loading developed carried out under main operating In calculations observed quantities, an application symmetry with regard longitudinal axis used...

There is a large body of research devoted to hunting lions in the Sahara Desert [2]. In none of these, however, is any concern given to feeding the lion once it is captured. In this note, we propose feeding Stan Wagon to the lion. Place an orange in the middle of the Sahara Desert. Cut it up into a finite number of pieces and rearrange the pieces to form the Sun. The gravity of the Sun will the...

Multiphase impeller stirred tank reactors enhance mixing of reacting species used in a variety of chemical industries. These reactors have been studied based on Computational Fluid Dynamics (CFD) that can be used in the analysis, design and scale up of these reactors. Most of the researches done in this area are limited to single phase reactors, and a few remaining two phase flow investigat...

This paper presents an original interactive analysis method consisting of mathematical calculation based on theoretical mechanics and mechanics of materials, and dynamics simulation for quantifying outrigger reaction forces of a kind of hydraulic mobile crane, aiming to avoid the eventualities during normal operation as far as possible, for example, tipping-over. First, a three dimensional dyna...
