due to their advantages, omni-directional mobile robots have found many applications especially in robotic soccer competitions. however, omni directional navigation system, omni-vision system and kicking mechanism in such mobile robots have not ever been combined. this situation brings the idea of a robot with no head direction into existence, a comprehensive omni directional mobile robot. such...

In this study, a denoising method of smoothing spline is proposed to reconstruct parent β grain titanium alloys as supplement the past literatures. The mean orientation sample with bimodal microstructure can be well reconstructed similar size and negligible misorientation (<1°) compared traditional reconstruction result. second test case deals globularized α grains after multi-axial hot compres...
Bubbles stabilised by colloidal particles can find applications in advanced materials, catalysis and drug delivery. For applications in controlled release, it is desirable to remove the particles from the interface in a programmable fashion. We have previously shown that ultrasound waves excite volumetric oscillations of particle-coated bubbles, resulting in precisely timed particle expulsion d...
In this study, in order to understand the nanostructure of FeCrNi steels laser powder bed fusion (LPBF) process, directional solidification was simulated using large-scale molecular dynamics simulation (LSMDS). For purpose an atomic box with a dimension 70×40×60(nm3) including random dispersion Fe, Cr and Ni created. Then, two different fixed temperatures were considered for left right side dur...
Based on fundamental equations of the elasticity theory, a unified higher-order shear deformation theory is developed for bending and free vibration analysis functionally graded (FG) microplates with porosities. The modified strain gradient employed to capture size effects. Bi-directional series hybrid shape functions are used solve problems. Several important effects including thickness-to-mat...
In design and analysis, standard references assume the pedestrian flow as unidirectional. In reality however, pedestrian flow is usually bi-directional. The main question pursued in this paper is that whether the main characteristics of pedestrian flow the same under uni- and bi-directional conditions. In order to achieve this goal, effect of bi-directional stream is inv...
The dogleg severity is one of the most important parameters in directional drilling. Improvement of these indicators actually means choosing the best conditions for the directional drilling in order to reach the target point. Selection of high levels of the dogleg severity actually means minimizing well trajectory, but on the other hand, increases fatigue in drill string, increases torque and d...
