The re-examination of the colloid filtration theory revealed that it is crucial to consider the effect of surrounding solid grains on the flow field in order to gain more realistic results. The application of the colloid filtration theory on the air bubble showed that more collo…
A model describing the dynamics of a floating body by solving the NS-equations in a moving grid framework with free surface is presented. The model has several interesting features, like the peculiar way of describing: a) the grid movements; b) the slip boundary conditions in pr…
Electrical resistance tomography is a technique able to identify solid/liquid distribution in packed beds by identification of the bed conductivity and its subsequent modelling as a function of electrical properties of each phase. It can be performed via an array of equispaced e…
The applicability of the present model of an ideal two-probe impedance measurement, treated as a current injection/extraction problem, is demonstrated for a fairly good conductor, in this case a nickel-base superalloy. However, the scope of this model may be extended to good sem…
It is concluded that the presented simulation environment Matlab/SimuLink/Comsol is capable of solving a large range of integrated HAM problems. Furthermore, it seems promising in accurately solving modelling problems that are caused by the presence of different time scales and/…
An application of the digital extended Kalman filter has been presented for the problem of estimating the absolute orientation of SemiQuad, a 2D dynamically stable walking robot. There are some differences between simulations and experiments, but the results still prove the abil…
In this chapter, the method to generate a trajectory of a running motion with minimum energy consumption is proposed. It is useful to know the lower bound of the consumption energy when we design the bipedal robot and select actuators. The exact and general formulation of optima…
The CPG based approach for combining rhythmic movements in two-legged robotic systems does work and produces less calculating costs than inverse kinematics (Tevatia, 2000), it results in smoother movements than using simple look up tables, and is easier to realize than neural ne…
This paper proposed a new method for humanoid robot gait generation based on several objective functions. The proposed method is based on multiobjective evolutionary algorithm. In our work, we considered two competing objective functions: MCE and MTC. Based on simulation and exp…
