Controlling a robot astronaut to move in the same way as human realize wide range of motion space station is an important requirement for astronauts that are meant assist or replace astronauts. However, nonlinear and strongly coupled multibody dynamic system with multiple degrees freedom, whose characteristics complex. Therefore, implementing wide-ranging control tremendous challenge robotic technology. This article presents stable method stations based on dynamics. Focusing astronauts'...
To obtain sustainable economical oil production and recovery of investment, some fields adopted the strategy multilayer commingling at an early stage. This leads to interlayer interference losing part recoverable reserves. In this paper, dynamic behaviors arbitrary in heavy reservoirs are analyzed. Based on non-Darcy flow equation, Buckly–Leverett material balance a mathematical model is obtained. Oil water relative permeability, saturation, bottom hole pressure microelement iteration method...
The effect of deep HF etching on the surface quality and figure fused silica optics has been investigated systematically. Fused samples (100 mm in diameter x 10 thick) were manufactured using conventional grinding polishing process. These processed are etched with different removal depth. Initially, is characterized terms roughness defects. Many digs not more than 1μm emerged which originates from micron cracks crack pits. worsened frosted sample. While submillimeter subsurface damage...
Legged locomotion over various terrains is challenging and requires precise perception of the robot its surroundings from both proprioception vision. However, learning directly high-dimensional visual input often data-inefficient intricate. To address this issue, traditional methods attempt to learn a teacher policy with access privileged information first then student imitate teacher's behavior input. Despite some progress, imitation framework prevents achieving optimal performance due gap...
Abstract Multi-scale natural fractures bring challenges in geological modeling and flow simulation of carbonate reservoirs. History matching is extremely difficult due to significant heterogeneities uncertainties, especially for those wells identified as "dominated by fractures". A novel, systematic approach applied model explicitly, perform efficiently eventually match the production history accurately. First, a discrete using unstructured triangular grids were built fully resolve geometry...
Ship roll motion is often the critical factor for offshore operations due to its lack of damping mechanism. This paper demonstrates a dynamic simulation scheme an active reduction system using free-flooding tanks controlled by vacuum pumps. The two in are installed on each sides catamaran. tank hatches opened sea and air chambers both connected duct. Vacuum pumps valve with stabilization controller provides desired filling level tank. ship model single degree freedom roll. hydrodynamic...
The robot astronaut is a multi-body dynamics system with multi-degrees of freedom, nonlinearity and strong coupling. Its motion control operation target are in micro-gravity environment, which the natural floating state. On space station, influenced by internal force, contact inertial force joint friction. At this point, collision between station due to movement will greatly influence safety may cause serious damage. In paper, we propose strategy based on compliant dual feed forward torque...
Transient pressure analysis is a crucial tool to forecast the production performance during exploration and process in gas reservoirs. Usually, regular shaped outer boundary assumed previous studies for well-testing analysis, which just simplification of practical cases cannot reflect actual boundaries In this paper, mathematical model established analyze transient behaviors horizontal well an arbitrarily reservoir. Dimensionless treatment, Laplace transformation, element method are applied...
With the rapid development of automobile industry, impact engine noise on social environment and human body can’t be ignored any longer. Noise pollution has become an important source environmental pollution. This paper analyses harm classification noise, putting forward reduction measures in view increasingly serious The technology plays role industry.
