[Software Engineering] 90323119 DL : 0: This thesis aimed to eliminate tracking error of traveling a circular profile on the CNC machine tools. Friction is one of the most significant source of nonlinear disturbance for the motion control which caused by the relative motion of different contact surface at the low velocity. The nonlinear component of friction such as static friction (stiction) and the Coulomb friction should be overcome so that the tracking error will be eliminated. When the X-Y tables are tracking a circular profile, quadrant glitches appear at ninety degrees intervals, i.e. the motion of one axis has a zero velocity crossing and reverses direction.-This thesis is aimed to eliminate tracking error of traveling a circular profile on the CNC machine tools.

[Mathimatics-Numerical algorithms] Cpp-openlb DL : 0: 这个算例采用格子Boltzmann方法模拟不稳定绕柱流的情况。在固体边界出采用反弹格式进行处理。-this example examines an unsteady flow past a cylinder placed in a channel. The cylinder is offset somewhat from the center of the flow to make the steady-state symmetrical flow unstable. At the inlet, a Poiseuille profile is imposed on the velocity, where as the outlet implements an outflow condition: grad_x p = 0. At Reynolds numbers around 100, an unstable periodic pattern is created, the Karman vortex street.

[Algorithm] wind_model DL : 0: The evolution the speed of wind according to time is modelized by a function analytical or generated by a statistical law starting the data of measurement for a given site. In a context of theoretical modeling, the profile of wind must satisfy two criteria: 1) The duration of the profile must be limited to reduce the time of simulation 2) The profile of the wind must be representative of the characteristics of the deposit (intensity, variability, statistical distribution…). In this study, we represented the evolution the speed of the wind, by a scalar function which evolves/moves in time, modelized in deterministic form by a sum of several harmonics. Profile of the wind simulated with a mean velocity of 8.2m/s.-The evolution the speed of wind according to time is modelized by a function analytical or generated by a statistical law starting the data of measurement for a given site.
